Hi,

You can create multiple user groups for your module and use them to restrict access per field

By creating multiple fields in the view:

1. Create a 'stage' field.​

2. Create multiple 'stage' field tags in the view and restrict them accordingly. i.e In the respective View Architecture:
​field name="stage" groups="module_name.user_group_id_1,module_name.user_group_id_2" readonly=1
​​field name="stage" groups="module_name.user_group_id_3" readonly=0

In the above snippet, users belonging to user_group_id_1 and 2 will be able to view the field but cannot edit them. Users belonging to user_group_id_3 will be able to both view and edit the field.

By using a compute method:

1. Create a new boolean compute field that depends on any field with default value.

can_edit = fields.Boolean(compute='_compute_can_edit')

api.depends('any_default_field')
def _compute_can_edit(self):
	​for record in self:
	​	​if self.env.user.has_group('module_name.user_group_id_1'):
	​	​	​record.can_edit = True
	​	​else:
	​	​	​record.can_edit = False

2. In xml view:

field name="can_edit" invisible="1"
field name="stage" attrs="{'readonly':[('can_edit', '!=', True)]}"

In the above snippet only users belonging to user_group_id_1 will be able to edit the field.

Hope this helps.
