server-tools/auth_dynamic_groups

Description

This module allows defining groups whose membership is a condition expressed as python code. For every user, it is evaluated during login if she belongs to the group or not.

Usage

Check Dynamic on a group you want to be dynamic. Now fill in the condition, using user which is a browse record of the user in question that evaluates truthy if the user is supposed to be a member of the group and falsy if not.

There is a constraint on the field to check for validity if this expression. When you're satisfied, click the button Evaluate to prefill the group's members. The condition will be checked now for every user who logs in.

Example

We have a group called Amsterdam and want it to contain all users from city of Amsterdam. So we use the membership condition

user.partner_id.city == 'Amsterdam'

Now we can be sure every user living in this city is in the right group, and we can start assigning local menus to it, adjust permissions, etc. Keep in mind that view overrides can also be restricted by a group id, this gives a lot of possibilities to dynamically adapt views based on arbitrary properties reachable via the user record.
