Hi all ! 

I want to customize the UI of my odoo instance for each user.

Example: if a user has the permission (access right) to res.partner, he could see the "Contact" view. So he will be only able to see what he's allowed to (by permissions).

I started creating groups with access rights, then I added a user to this group. But when I tried to log with him, I got an error 

"Sorry, you are not allowed to access this document. Only users with the following access level are currently allowed to do that:\n- Purchases/User\n\t- Purchases/Manager\n\t- Inventory/User\n\t- Accounting & Finance/Billing\n\t- Other Extra Rights/Portal\n\n(Document model: purchase.order)"

Seems like "basic" UI menu allows access to "purchase.order" model but I don't want to. I can't find where this parameter is given.

Could someone explain me the good way to handle UI with permissions please ?

Thank you :-)
