Create function field that returns a value based on the user's group and then use attrs attributes on fields to control.

Reference :https://answers.launchpad.net/openobject-server/+question/178779

Hi, you can use this as example...

'name': fields.char('Name', size=128, read=['base.group_userA'], write=['base.group_userB'] )

Read will allow the user group to view and Write will allow the user group to edit the field..

*EDITED*

One solution is to combine a function field with the attrs tag:

.py:

def _get_uid_is_manager(self, cr, uid, ids, field_name, arg, context=None):
        res = {};
        manager_group_id = self.pool.get('ir.model.data').get_object(cr, uid, 'base', 'group_hr_manager').id
        manager_ids = self.pool.get('res.user').search('groups_id', '=', manager_group_id);
        for obj in self.browse(cr, uid, ids, context=context):
            res[obj.id] = uid in manager_ids;
        return res;

'uid_is_manager': fields_function(_get_uid_is_manager, type='boolean', method=True, string='Current User is Manager?'

.xml:

<field name="name" attrs="{'readonly': [('uid_is_manager' ,'=', True)]}"/>
<field name="date" attrs="{'readonly': [('uid_is_manager' ,'=', True)]}"/>

Regards.

Use fields_get to achieve this:

Eg. 

@api.model
def fields_view_get(self, view_id='OdooModule.test_form_view', view_type='form', toolbar=False, submenu=False):
res = super(Test, self).fields_view_get(view_id=view_id, view_type=view_type, toolbar=toolbar,
submenu = submenu)
doc = etree.XML(res['arch'])
if not self.env.user.has_group('group_admin') or self.env.user.has_group('group_ad_doctor'):
for node in doc.xpath("//field[@name='laboratory']"):
node.set('modifiers', '{"readonly": true}')
for node in doc.xpath("//field[@name='test_type_id']"):
node.set('modifiers', '{"readonly": true}')

for node in doc.xpath("//field[@name='patient_id']"):
node.set('modifiers', '{"readonly": true}')


res['arch'] = etree.tostring(doc)
return res
