Implied_ids and users in groups in odoo 8

Question

What is the difference between these two in odoo security file.

<field name="users" eval="[(4, ref('base.user_root'))]"/>
<field name="implied_ids" eval="[(4, ref('base.group_hr_manager'))]"/>

Please anyone explain this!!

Answer 1

1. users are the group members which will get all the group privileges. The model behind is res.users. Example: Users in the group sales manager will see the sales configuration menu.

2. implied_ids are inherited group privileges. A group which inherits other groups, will get all the other groups rights in top of their own. The model behind is res.groups. Example: The group sales manager will inherit all rights from group see all leads which also implies the rights from group see own leads.
