I have a custom model which have a many2one field about account and one2many field of sale orders.
In the tree view and form view, I just want the manager to see the account and sales information, base users would only consult the stardard info.
But even limiting the views with groups, the system ask for sale_order read permission
Is the read permission on the model mandatory ? Does it mean that a base user will have read permission on the account model ?
