Dynamic attributes

Dynamic attributes (attrs)

The format consists in key as the name of the attribute and the value is a tuple of three elements with the condition:

<field name="field_name" attrs="{'invisible': [('other_field', '=', False)]}" />

It is possible to use value from the form in the condition

<field name="field_name" attrs="{'invisible': [('other_field', '=', field3)]}" />

Note

They are converted in json_attrs format in the backend automatically.

JSON Dynamic attributes (json_attrs)

Caution

This only works with webclient.

It uses the conschek library to evaluate the conditions.

Ant the format consists of a JSON with the following structure:

{
    "condition": "AND",
    "rules": [
        {
            "field": "other_field",
            "operator": "=",
            "value": false
        }
    ]
}

Inside the xml will be like this:

<field name="field_name" json_attrs="{'invisible': {'condition': 'AND', 'rules': [{'field': 'other_field', 'operator': '=', 'value': false}]}}" />

It is possible to use value from the form in the condition

{
    "condition": "AND",
    "rules": [
        {
            "field": "other_field",
            "operator": "=",
            "value": "$field3"
        }
    ]
}

And is possible to nest conditions

{
  "condition": "AND",
  "rules": [
    {
      "condition": "OR",
      "rules": [
        {
          "field": "age",
          "operator": "<",
          "value": 18
        },
        {
          "field": "age",
          "operator": ">",
          "value": 65
        }
      ]
    },
    {
      "field": "citizenship",
      "operator": "=",
      "value": true
    }
  ]
}
