# Entities

# Interfaces

# Understanding interfaces

Interfaces allow access to the system with preset values for

- Wrapper
- Stylesheet
- Template
- Language
- User context

When accessing the interface the user is redireceted to the main page with the correct parameters set. In case the user context is active, a session with a matching user profile is also created i process.

The following types of record operations are allowed

- Create new records
- Update an existing record

### <span class="mw-headline" id="bkmrk-create-operations-1">Create operations</span>

Create operations require no additional security information and can be used directly.

URL for testing the interface:

http://\[server name\]/\[application\]/webinterface?\[interfacename\]

### <span class="mw-headline" id="bkmrk-update-operations-1">Update operations</span>

When updating an existing record a security token must be passed along to the interface:

- The right data is displayed for the user
- Bind user session to this piece of data

A security token contains

- a reference to the record
- a timestamp when the token was issued
- a signature that guarantees that the server issued the token

URL for testing the interface: http://\[server name\]/\[application\]/webinterface?\[interfacename\]=\[security token\]

Security tokens can be generated in various ways

- Create a status action that generates a notification
- Administrator tool: Designer &gt; Modules &gt; Admin Services &gt; BuildSecuityToken
- Add the special "Token display" field to a solution

### <span class="mw-headline" id="bkmrk-questionnaires-and-e-1">Questionnaires and email invitations</span>

Generation of security tokens are closely tied to the use of questionnaires and status actions.

The guide [Questionnaires](https://docs.tsnocode.com/books/entities/chapter/questionnaires "Tutorial/Questionaires") covers such an example.

# Using interfaces

Interfaces are access points for external users (someone using the system without a login).

For a more detailed description, please read: [Understanding interfaces](https://docs.tsnocode.com/books/entities/page/understanding-interfaces "Integration/Interface")

### <span class="mw-headline" id="bkmrk-basic-configuration-1">Basic configuration</span>

An interface has the following configuration options

- Interface URL 
    - Unique name of the service
- How should the interface behave 
    - Look and feel: 
        - Wrapper: "Outer" page design, possibly mimicing an existing website
        - [Template](https://docs.tsnocode.com/books/templates/page/form-templates "Templates"): "Inner" page design
        - Stylesheet: Color, font, styles etc.
    - Language: Default language set on page
    - [Use questionnaire](https://docs.tsnocode.com/books/entities/chapter/questionnaires "Tutorial/Questionaires"): Use multiple pages in stead of one big page
- What is the external user allowed to do 
    - Proxy user profile
    - Allow UPDATE of existing records
    - Allow INSERT of new records

Note that using and interface is no different than being a normal user: The external user will mimic the provided system user, and this user must have the appropiate permissions.

### <span class="mw-headline" id="bkmrk-email-tokens-for-acc-1">Email tokens for access to existing records</span>

A common usage is sending email tokens to external users.

Tokens will allow a certain user to update the content of a certain record. Usually these are tied together, where the email of the user is a field in the record.

Tokens contain a timestamp, so it is possible to invalidate the token after a specified amount of time

- **Token expiry**: Maximum allowed age of the token

Please not that tis use requires some additional configuration of the Status action that sends the emails.

### <span class="mw-headline" id="bkmrk-other-interface-opti-1">Other interface options</span>

Control what happens after an update or insert operation

- **Succes message**: Displayed message (if not using questionnaire interface)
- **Failure message**: Displayed message (if not using questionnaire interface)
- **Redirect**: URL to send user to after updating/inserting their data

Extra security features

- **CAPTCHA**: User must take human test before using the interface (prevents robots from injecting data)
- **IP filter**: Specify which IP's are allowed to use the interface (prevent users from known problem countries)

# Questionnaires

# Step-by-step questionaire for anonoumous users

1. Create a new solution and test it
2. Create an interface 
    - \[solution\] &gt; Advanced &gt; Interfaces ... ADD 
        - Interface 
            - Active: X
            - Unique name: \[unique name across all interfaces\]
        - Anonoumous user 
            - Active: X
            - **Insert items: X**
            - Use questionaire style interface: X
3. Set the order of fields 
    - \[solution\] &gt; Wizards &gt; Questionaire order 
        - Enter values 
            - 0 = disabled in questionaire
            - Numbers dont need to be consecutive
        - Accept with Submit
4. Ensure that anonoumous users can access to the solution 
    - UserID = 10003 must have a group that has permissions
5. Test link using 
    - http://\[server name\]/\[application\]/webinterface?\[interfacename\]=1

# Step-by-step questionnaire for specific users

1. Create a new solution and test it 
    - Make sure that solution contains an field of the Email type
2. Create an interface 
    - \[solution\] &gt; Advanced &gt; Interfaces ... ADD 
        - Interface 
            - Active: X
            - Unique name: \[unique name across all interfaces\]
        - Anonoumous user 
            - Active: X
            - **Update items: X**
            - Use questionaire style interface: X
3. Create an status action that sends emails with tokens 
    - Required: Set the correct interface
    - Option: Set a status that is used if email sending fails
4. Set the order of fields 
    - \[solution\] &gt; Wizards &gt; Questionaire order 
        - Enter values 
            - 0 = disabled in questionaire
            - Numbers dont need to be consecutive
5. Ensure that anonoumous users can access to the solution 
    - UserID = 10003 must have a group that has permissions
6. Test solution 
    - Goto frontend
    - Create new record and set status to that of the action trigger
    - Test token 
        - Collect from you own email OR
        - Check the email queue in the designer

# Controlling the status flow

Status after **first update**:

1. Designer &gt; \[Solution\] &gt; Advanced &gt; \[Interface\]
2. Update the value "Status after update"

Status after questionaire **completion**:

1. Designer &gt; \[Solution\] &gt; Advanced &gt; Functionality - Questionaire - Messages
2. Update the value "Final status"

# Questionnaire building process

In order to create a complex questionaire you first choose between copying a solution and creating from scratch.

We strongly reccomend the copying if you are unfamiliar with designing solutions.

### <span class="mw-headline" id="bkmrk-creating-from-scratc-1">Creating from scratch</span>

Steps to create a questionaire includes

1. Create solution and add fields
2. Configure questionaire order and messages
3. Setup inetrface for external users
4. Configure email invitation
5. Build report template

For detailed information read the section **Setting up a questionaire with report** below.

### <span class="mw-headline" id="bkmrk-copying-a-solution-1">Copying a solution</span>

Steps include

1. Backup existing solution 
    - *Entity* &gt; Advanced &gt; Backup &gt; Create new backup
2. Promote backup to standard 
    - Click top backup &gt; Promote to standard
3. Create instance from standard 
    - Quickstart &gt; Repository &gt; *choose* &gt; Create this item
4. Deploy solution 
    - *New entity* &gt; Deploy live

# Setting up a questionnaire with report

### <span class="mw-headline" id="bkmrk-field-types-1">Field types</span>

Complex questionnaires contain fields for sending the questionnaire and answering questions.

Depending on how the questionnaire is distributed to the users, you will also need contact information such as name and email.

#### <span class="mw-headline" id="bkmrk-questions-and-scores-1">Questions and scores</span>

For normal questions that are answered once use the field type: **Complex question**

A complex question contains a single question and multiple answer. Each answer contains

- Value shown when selecting
- Response showed in report
- Color and icons
- Score

You can optionally calculate scores across multiple questions using the field: **Calc: Complex question (sum)**

#### <span class="mw-headline" id="bkmrk-support-for-multiple-1">Support for multiple questions</span>

Multi line questions consists of the following

- Multiline: Location editor
- Multiline: Complex question

There should only be exactly one **Multiline: Location editor**, while there can be multiple **Multiline: Complex question**.

First the users enters lines values in the location editor. Then questions are created for each **Multiline: Complex question** - one for each line entered in the location editor.

Lines can be removed by clicking the checkbox next to them in the **Multiline: Location editor**.

### <span class="mw-headline" id="bkmrk-questionnaire-1">Questionnaire</span>

Normal users will see data represented as a form, while external users will most often have displayed a step-by-step questionnaire.

Inclusion of fields and their page order is managed in the questionnaire order editor: **Entity &gt; Advanced &gt; Questionnaire: Question order**

Note that

- If a field have a sortorder of 0 (zero), it will never be displayed for external users.
- Order numbers are not dispayed to the user and do not need to be consecutive - ex. 10, 20, 30 ...

The initial and final messages of the questionnaire is edited in: **Advanced &gt; Questionnaire: Messages**

From a normal view normal users can see data in questionnaire form, by appending and extra command to the address bar in the browser: **&amp;StepNumber=0**

### <span class="mw-headline" id="bkmrk-granting-access-for--1">Granting access for external users</span>

The process consists of 2 activities

1. Add access for external users by adding a new permission
2. Add an interface for the solution: Advanced &gt; Interface: Add 
    - Enter a descriptive and unique name
    - Check "UPDATE"
    - Check "Use questionnaire style interface"

### <span class="mw-headline" id="bkmrk-sending-emails-with--1">Sending emails with links</span>

In order to send personalized message you solution will need to contain these fields

- Text: Enter the name of recipient
- Email: Email of the recipient

These fields are refered to in the message template in a status action, which is where subject and body of the email is edited.

A message is sent to the recipient, when a record in the system reaches a certain state.

### <span class="mw-headline" id="bkmrk-configuring-reports-1">Configuring reports</span>

Report are Word documents containing special tags where content from the records are merged into the document.

1. Create a new Word document
2. Write content and add special field tags 
    - Entity &gt; Advanced &gt; Template: Add &gt; Office &gt; (copy special tags)
3. Add template to the solution 
    - Entity &gt; Advanced &gt; Template: Add
    - Choose Word or PDF add
    - Uplaod the Word file

Note that certain configuration options for fontsize, margin etc. can be configured per solution: Entity &gt; Advanced &gt; Configurations

- GlyphPageWidthPercentage
- HeatmapColumnMaxCharacters
- renderExtraLinjeBeforeNotes
- renderExtraLinjeBeforePicture
- renderQuestionInTable

Often you will want at heatmap of the answered questions in first pages of the report. For this you add a field of the type: **Word heatmap index**

In case you want a dedicated button at the top of the page please add a field of the type: **Action button: Export template**

# Status

# Status Actions

The actions are fired when a certain condition is meet AND the item is in the parent status

- An item enters the status
- An item leaves the status
- Time has passed while an item was in this status

### <span class="mw-headline" id="bkmrk-timed-actions-1">Timed actions</span>

The time specified is relative to a value of the item

- Creation date
- Last change
- Last status update
- Dynamic **date field**

Time is specified in days and can assume both negative and positive values.

## <span class="mw-headline" id="bkmrk-action-types-1">Action types</span>

### <span class="mw-headline" id="bkmrk-notification-1">Notification</span>

This action sends an email for users or groups.

Various options for the target email exists, including

- Raw email: Static reference
- User: A specific user in the database
- Field value: The contents of another field 
    - Email
    - Phone (sent by SMS)
    - CPR nr (sent by eBoks)

Different types of content can be included in the emails

- Data from the record
- Document generated using data of the record
- Links to the record (internal users)
- Interface tokens (external users)

Read about special tags and formatting her [Tutorial/Status\_notifications](https://wiki.tsnocode.com/index.php?title=Tutorial/Status_notifications "Tutorial/Status notifications")

### <span class="mw-headline" id="bkmrk-task-create-1">Task create</span>

This will dynamically create new tasks for any '[Task list](https://wiki.tsnocode.com/index.php?title=FieldTask "FieldTask")' fields found in the solution.

### <span class="mw-headline" id="bkmrk-codeunit-1">Codeunit</span>

This action triggers the execution of a special codeunit: [Codeunit/Statusaction](https://docs.tsnocode.com/books/codeunit-reference/chapter/statusaction "Codeunit/Statusaction").

Except for timed actions you would implement this inside a [Codeunit/Formevents](https://docs.tsnocode.com/books/codeunit-reference/chapter/formevents "Codeunit/Formevents").

### <span class="mw-headline" id="bkmrk-export-1">Export</span>

The template is optional: If no template is found raw XML will be generated (FTP/mailto will not work).

The following types of routing are supported for template based exports

- Local file system (optionally a mapped share)
- Remote FTP server
- Sent by email

Please note that export actions are handled in seperate threads (performance), and there is no guarantee the operation succeds (tjeck the event log)

#### <span class="mw-headline" id="bkmrk-values-from-record-1">Values from record</span>

The target reference may contain field references in the {FIELD} format, that will be populated at runtime.

Other special tags include

- {SagID}
- {DataID}
- {Resume}
- {NanoTime}

Note that values in records are not filtered for illegal og troublesome characters (such as \\ or . )

#### <span class="mw-headline" id="bkmrk-usage-examples-1">Usage examples</span>

<table id="bkmrk-routing-syntax-synta"><tbody><tr><th>Routing</th><th>Syntax</th><th>Syntax example</th></tr><tr><td>File system</td><td>*local filesystem path*</td><td>c:\\exportFolder\\{GROUP}\\{TITLE}.docx</td></tr><tr><td>FTP server</td><td>*ftp location and connection string*</td><td>[ftp://username:password@acme.com/exportFolder](ftp://username:password@acme.com/exportFolder)</td></tr><tr><td>Send by mail</td><td>"mailto:"+\[email\]+":"+\[subject\]+":"+\[filename\]</td><td>[mailto:boss@acme.com:Attention:your\_2013\_report](mailto:boss@acme.com:Attention:your_2013_report)</td></tr></tbody></table>

### <span class="mw-headline" id="bkmrk-shift-status-1">Shift status</span>

A status merely changes the status to a new value.

This type of action only makes sense to use in timed actions.

### <span class="mw-headline" id="bkmrk-webhook-1">Webhook</span>

This action performs an HTTP-request with parameters from the updated item and update the item based on the result.

<table class="wikitable" id="bkmrk-datapoint-%C2%A0-type-not"><tbody><tr><th>Datapoint</th><th> </th><th>Type</th><th>Notes</th></tr><tr><td>url</td><td>Required</td><td>String</td><td>The url that is to be called. This supports input of parameters from the item.</td></tr><tr><td>method</td><td>Optional</td><td>String</td><td>The HTTP-method of the call, one of: "POST", "GET", "PUT" or "DELETE". Default: "GET".</td></tr><tr><td>type</td><td>Optional</td><td>String</td><td>The datatype of data returned, supported types: "json", "raw" or "XML". Default: "json".</td></tr><tr><td>headers</td><td>Optional</td><td>Map</td><td>A map of extra headers that should be set</td></tr><tr><td>params</td><td>Optional</td><td>Map</td><td>Path parameters that should be set and send.</td></tr><tr><td>body</td><td>Optional</td><td>String</td><td>A string that will be set and send.

If type is "raw", only the first item in this list will be updated, and it will be set to the entire response.

If type is "json", attributes with keys formatted as `[FIELDNAME]` will be updated from the given key in the returned data.

</td></tr></tbody></table>

In `params` and `body`, values formatted as `[FIELDNAME]`, will be filled with data from the record.

#### <span class="mw-headline" id="bkmrk-sample-1">Sample</span>

```
{
  "url": "http://localhost:3001/users/1",
  "method": "PUT",
  "type": "json",
  "headers": {
    "authorization": "Bearer XYZ",
    "Content-type": "application/json"
  },
  "params": {
    "param": "DATA"
  },
  "body": {
     "id": 1,
     "name": "[NAME]",
     "email": "john.doe@example.com"
  },

    "[NAME]": "name"
  }
}
```

# Status Notifications

## <span class="mw-headline" id="bkmrk-special-tags-for-not-1">Special tags for notification</span>

### <span class="mw-headline" id="bkmrk-data-in-emails-1">Data in emails</span>

Dynamic field content can be inserted using {FIELD\_SYSTEM\_NAME} syntax.

For status notification content the following tags will also be populated

- {USER}: Name of the user
- {RESUME} Name of the record
- {LINK}: Clickable link to the record (se below)
- {NOLINK}: Do not include any record links
- {RAWLINK}: Link without any HTML markup

Note that a link to record will be included at the bottom of the message, unless a LINK, RAWLINK or a NOLINK placeholder can be found.

### <span class="mw-headline" id="bkmrk-create-attachments-1">Create attachments</span>

Additionally rendered files can be attached using the following syntax

```
[REPORT:123456]
```

The number refers to the ID of the template to render.

This will render the the template, and attach the resulting file as an attachment to the email.

Default name of the file is "attachment". In case you want a custom name add this in the tag (ex. "Foobar" )

```
[REPORT:123456-Foobar]
```

Tip: It is perfectly OK to use templates with any tags in it, but in that case you might consider using the link approach below.

Files from the record can be attached using the following tag, where 123456 is the ID of the field.

```
[FILES:123456]
```

### <span class="mw-headline" id="bkmrk-dynamic-links-1">Dynamic links</span>

URLs can be entered by using {APPURL} in front of a relative reference. Example:

```
{APPURL}/login
```

### <span class="mw-headline" id="bkmrk-static-file-links-1">Static file links</span>

If you only need static files, just upload them to the media library and put a link in the mail

1. Upload to media library: Ressources &gt; Media files &gt; Add
2. After upload right-click "show" button and select "copy link"
3. Paste the link into a notification (no html encoding is needed)

Note that this will only make a link to the file (the file is not added as an attachment).

# Entity Settings

Below is the full list of settings found on any given Entity. This is the expanded view, which is available when toggling the slider in the top right. Below the image are explanations of every setting.

[![image.png](https://docs.tsnocode.com/uploads/images/gallery/2025-08/scaled-1680-/zoofkQFTdAspCuav-image.png)](https://docs.tsnocode.com/uploads/images/gallery/2025-08/zoofkQFTdAspCuav-image.png)

<span style="text-decoration: underline;">Top buttons</span>

**deploy live:** Submits all new entity and field changes, so they are rendered in the application.

**backup:** Access and create new backups

**delete:** Removes the entity entirely. Record data is not lost from this action.

**bulk update:** ???

<span style="text-decoration: underline;">General</span>

**Active:** Determines whether or not records from the entity is available in the application. It is often useful to deactivate unused entities instead of deleting them, in case you need to look at what once was.

**System name:** What the entity is called in the database and is sometimes used in configurations where a specific entity needs to be pointed out. An entity's system name never changes.

**Display name:** What the entity is called from the point of view of the user, and can be changed at any point if needed. Below is what the plural name of the entity should be for the purposes of list views.

**Description:** Has no function. Is merely a reminder in the designer of what the entity is.

**Dev notes:** A place for the developer to note things about the entity. Only used for this, is never outputtet in the frontend.

**Icon/image:** Choose an icon to display next to the entity selection in the application navigation menu. The button **Icon-selector** below helps with this. Example: [![image.png](https://docs.tsnocode.com/uploads/images/gallery/2025-08/scaled-1680-/6llh05tEZKZ58KqJ-image.png)](https://docs.tsnocode.com/uploads/images/gallery/2025-08/6llh05tEZKZ58KqJ-image.png)

**edit instructions, header and script:** Advanced menu to insert custom css and JavaScript to adjust the appearance and behaviour of the records.

<span style="text-decoration: underline;">Workflow</span>

**Initial status:** The status that all records should start in (before first save).

**Deleted status:** The status that records should enter, when the delete button is pressed. When set, the delete button will appear in the front end, and the delete method in the API will work. A status has to be marked as "Hidden data" to appear in this list.

**Recursive delete/hide (parent trigger):** Also delete records in this entity when a record in a parent entity is deleted.

**Satelite data synchronization:** Enable synchronization of records to another TS application.

<span style="text-decoration: underline;">Functionality</span>

**Check for Duplicates using unique key(s):** This feature prevents any record from being created if another records shares its combination of unique field values. Will also prevent one record from being edited to be the same as another. This only works if at least one field is required to be unique.

**Measure time spent editing / viewing each item:** Logs approximate number of seconds, that a user had a record open, and what status that record was in. Required a re-deploy of the entity.

**Allow Internationalization:** Enables the internationalization system for this entity. Without this translations will not work.

**Offline enabled:** Enable offline functionallity for this entity. Eg. allows for creation of record without an active connection to the server, if the entity has been viewed once.

**Use Revision log to build log of all changes:** Creates a log of all future changes to the records. Includes when and by whom the changes were made.

**Use Access log to register user access to each item:** Creates a log of when a user opens a record in this entity.

**Use Status log to register time in each status:** Creates a log of every time a record changed status, including: from-status, to-status, assigned at, assigned-by and waittime.
