Limiting access to fields in models
In some cases, we may need more fine-grained access control, and we may also need to limit access to specific fields in a model.
It is possible for a field to be accessible only by specific security groups, using the groups attribute. We will show how to add a field with limited access to the Library Books model.
How to do it...
To add a field with access limited to specific security groups, perform the following steps:
- Edit the model file to add the field:
private_notes = fields.Text(groups='base.group_system')
- Edit the view in the XML file to add the field:
<field name="private_notes" />
That's it. Now, upgrade the addon module for the changes in the model to take place. If you sign in with a user with no system configuration access, such as demo in a database with demonstration data, the Library Books form won't display the field.
How it works...
Fields with the groups attribute are specially handled to check whether the user belongs to any of the security...
