For a full record extension functionality using, you need to perform some additional actions. Below, a simplified implementation procedure can be found.

1. Create an extension model as described above.
2. Create necessary attributes and bind them to the model.
   • You can add attributes out of the created model using the appropriate related list.
3. Create a new widget using <rem> or <remform> SimpleTags (based on the widget planned location, a record form or a portal page).
4. Add newly created widget to a record form using the Form Layout functionality (or add it to the appropriate portal page using the portal pages configuring functionality).

Example of usage 1

For example, you need to extend your Task table with some attributes allowing you to handle some daily duties. To do it, follow the procedure described above:

Create an extension model for this table.

Create attributes (consider which fields could be created on this record form within this task). There should be a single attribute for every single for field.

Create a form widget as described below and save it:

<rem modelId="{data.model_id}" tableName="{data.table_name}" recordId = "{data.record_id}" />

(() => {
  window.s_widget_custom = window.s_widget_custom || {};
  const parameter = new URLSearchParams(window.location.search).get('model_id');
  s_widget.setFieldValue('model_id', parameter);
  s_widget.setFieldValue('table_name', window.s_form.getTableName());
  s_widget.setFieldValue('record_id', window.s_form.getUniqueValue());
})();

Add this widget to the record form view using the Form Layout functionality:

Navigate to a record form using the URL looking like: https://instance.example.com/record/task?model_id=XXXXXXXXXXXXXXXXX

After that, a form containing fields defined by attributes bound to the model specified is displayed.

Example of usage 2

Use RE model to display attributes of some record on the form you need. For example, you need to see information about the user who initiated a task. This information isin RE attributes for the Usertable. Here, you can add read-only RE attributes of the User table to the Task table. That is, you can display RE models of table A on the form of table B.

This configuration requires the following essences:

• RE model and attributes for the User table
• REM widget for the User table
• REM widget for the Task table

In the tabs below, you will find examples of scripts and necessary settings values.

To do this, you need to create the following records:

1. Create a widget for the User table with the following values:

<rem modelId="{data.model_id}" tableName="{data.table_name}" recordId = "{data.record_id}" />

( () => {
        window.s_widget_custom = window.s_widget_custom || {};
        const parameter = new URLSearchParams(window.location.search).get('model_id');
        s_widget.setFieldValue('model_id', parameter);
        s_widget.setFieldValue('table_name', window.s_form.getTableName());
        s_widget.setFieldValue('record_id', window.s_form.getUniqueValue());
})();

2. Create a RE model with the attributes you need for the User table.

3. Add the widget you created on step 1 to the User form.

4. Navigate to a record form using the URL looking like: instance.example.com/record/user?model_id=XXXXXXXXXXXXXXXXX

The X's here stand for the ID of the model you created on step 2.

Fill in the fields and save the record.

5. Create a widget for the Tasktable with the following values:

<div>
<rem modelId="{data.model_id}" tableName="{data.table_name}" recordId = "{data.record_id}" readOnly="true"/></rem>
</div>

( () => {
 
                s_widget.setFieldValue('table_name', 'user');
 
                s_widget.setFieldValue('model_id', '{id of the RE model created on Step 2}');
 
                s_widget.setFieldValue('record_id', '{id of the User record created on Step 4}');
 
                s_widget.setFieldValue('table_name', 'task');
 
 
})();

6. Add the widget you created on step 5 to the Task form.

7. Result. The Taskform has read-only values of RE attributes from the User record.
