Apps development
App extra columns
Apps can extend existing tables with extra columns to store additional data.
Usage
In your app manifest.json, you can define extra columns for a table by adding a extra_columns
property like this:
...
"extra_columns": [
{
"kind": "user",
"columns": [
{
"name": "appx_myapp_column1",
"type": "varchar",
"size": 128,
"is_required": false,
"description": "Example of extra column in the 'user' table"
}
]
}
]
...
The extra columns should follow the Table Column schema.
Extra columns are removed from the database when the apps are deleted.
