How to use python condition for hiding edit button for a specifi group

Question

Hy,
I found great ressources on how to hide the edit button :
http://help.openerp.com/question/14340/how-to-remove-save-button-from-form-view/
It works perfectly.
Yet I would like to generate the false value for specific groups. Here is my different tests.

Failed : edit="[('project.group_project_manager','in',[g.id for g in user.groups_id]))]"
Failed : edit="[(12,'in',[g.id for g in user.groups_id])]"
Failed : edit="[(%(project.group_project_manager)d,'in',[g.id for g in user.groups_id]))]"
Fi

Obviously, it's not possible to get the current groups in view.
So the solution is to create a boolean in python file and then to use it in the view

You have to uncheck the role Write for those groups in Configuration -> Technical -> Security

Not in Python code, but in the xml view, by using the attributes */attrs/* and *states* and */invisible/* for form elements.

The OpenERP way of restricting the edit rights for some groups is using Access Rights.
(Settings -> Technical -> Security -> Access Control Lists)
Or as csv file: /module/security/ir.model.access.csv

Still I agree, that it would be nice if Access Rights would completely hide the buttons, which does not happen (Access Error messages are displayed when a user tries a forbidden action).
