Restrict field access
=====================
This module was written to help developers restricting access to fields in a
secure and flexible manner on record level.
If you're not a developer, this module is not for you as you need to write code
in order to actually use it.
Usage
=====
To use this module, you need to inherit this mixin for the model whose fields
you want to restrict, and implement at least the following methods to do
something useful:
.. code:: python
class ResPartner(models.Model):
# inherit from the mixin
_inherit = ['restrict.field.access.mixin', 'res.partner']
_name = 'res.partner'
@api.multi
def _restrict_field_access_get_field_whitelist(self, action='read'):
# return a whitelist (or a blacklist) of fields, depending on the
# action passed
whitelist = [
'name', 'parent_id', 'is_company', 'firstname', 'lastname',
'infix', 'initials',
] + super(ResPartner, self)\
._restrict_field_access_get_field_whitelist(action=action)
if action == 'read':
whitelist.extend(['section_id', 'user_id'])
return whitelist
@api.multi
def _restrict_field_access_is_field_accessible(self, field_name,
action='read'):
# in case the whitelist is not enough, you can also decide for
# specific records if an action can be carried out on it or not
result = super(ResPartner, self)\
._restrict_field_access_is_field_accessible(
field_name, action=action)
if result or not self:
return result
return all(this.section_id in self.env.user.section_ids or
this.user_id == self.env.user
for this in self)
@api.multi
@api.onchange('section_id', 'user_id')
@api.depends('section_id', 'user_id')
def _compute_restrict_field_access(self):
# if your decision depends on other fields, you probably need to
# override this function in order to attach the correct onchange/
# depends decorators
return super(ResPartner, self)._compute_restrict_field_access()
@api.model
def _restrict_field_access_inject_restrict_field_access_domain(
self, domain):
# you also might want to decide with a domain expression which
# records are visible in the first place
domain[:] = expression.AND([
domain,
[
'|',
('section_id', 'in', self.env.user.section_ids.ids),
('user_id', '=', self.env.user.id),
],
])
The example code here will allow only reading a few fields for partners of
which the current user is neither the sales person nor in this partner's sales
team.
Read the comments of the mixin, that's part of the documentation. Also have a
look at the tests, that's another example on how to use this code.
