Hello

for version 11, you can use below code.

to check if the use has a group_base try this :

if self.env.user.has_group('base.group_user') :

Hope this help you.

Best Thanks,

I think you need something like : You have created one many2one field for Groups. In which, you want to list number of groups only that assign with current login user. Right? If yes, then I can suggest one way to you

First, you need to make one function field like group_ids in your current model. Then you have to set all groups of current login user in that field. Then you can use that field in domain.

Here is the example for function field (.py file)

def _get_user_groups(self,cr,uid,ids,fields,arg,context={}):

    res = dict.fromkeys(ids,[])

    user = self.pool.get('res.users').browse(cr,uid,uid)

    for partner in self.browse(cr,uid,ids):

        user_group_ids = map(int,user.groups_id)

        res[partner.id] = user_group_ids

    return res

_columns={

                    'group_ids':fields.function(_get_user_groups,type='many2many',relation='res.groups',

                        string='Groups'),

                    }

def _get_default_user_groups(self,cr,uid,context={}):

    user = self.pool.get('res.users').browse(cr,uid,uid)

    user_group_ids = map(int,user.groups_id)

    return user_group_ids

_defaults={

                    'group_ids':_get_default_user_groups,

                }

You must use _defaults because function field value set after record is save. So, at a time to create new record, if you don't use _defaults for group_ids field, there will not any group is set in this field.

In xml file you need to add field like :

<field name="group_ids" invisible="1" />

<field name="group_id" string="Group" domain="[('id','in',group_ids[0][2])]">

here is something more recent wich work for me :

ack_workflows = name of my module

group_manager = my group name
generate_project_task() = my method name

@api.multi
def generate_task_action(self):
    # On test l'appartenance au groupe
    flag = self.env['res.users'].has_group('ack_workflows.group_manager')
    if flag:
        order.generate_project_task()
    else:
        raise UserError('Vous n\'avez pas les droits pour réaliser cette action')

very good link for the security :

import for raise UserError :

from odoo.exceptions import UserError

I hope it useful
