Domain is working like select query of sql having where condition. We can give 'and' & 'or' conditions in that.

Example: <record model="ir.actions.act_window" id="crm_case_category_act_leads_all"> <field name="name">Leads</field> <field name="res_model">crm.lead</field> <field name="domain">['|', ('type','=','lead'), ('type','=',False)]</field> </record>

This will give the same output as following sql query: select * from crm_lead where type = 'lead' or type = 'false';

We can apply domain on some field like : <field string="Supplier" name="partner_id" domain="[('supplier', '=', True)]"/>

This will give suppliers from res_partner object.

Hi,

Domain notation using multiple and nested '|' and '&'
