Explaination of OpenERP domain filter with simple example:
Consider the following fields in XML view.
<field name="field1"/>
<field name="field2"/>
<field name="field3"/>
Single condition:
Simple condition in programming:
if field1 = 10
In OpenERP domain filter, it will be written as:
syntax : Each tuple in the domain has three fields -> ('field_name', 'operator', value)
field_name : a valid name of field of the object model or in the database table
operator : valid operators are =, !=, >, >=, <, <=, like, ilike, in, not in, child_of, parent_left, parent_right (openerp/osv/expression.py)
value : a valid value to compare with the values of field_name, depending on its type.
ie, domain = [('field1','=',10)] # where field1 should be a field in the model and 10 will be the value
or domain = [('field1','=',field2)] # where field1 and field2 should be the fields in the model
Condition AND
Simple condition in programming:
if field1 = 5 and field2 = 10
In OpenERP domain filter, it will be written as:
ie, domain = [('field1','=',5),('field2','=',10)]
or domain = [('field1','=',field3),('field1','=',field3)]
Note : Note that if you don't specify any condition at the beginning and condition will be applied.
Condition OR
Simple condition in programming:
if field1 = 5 or field2 = 10
In OpenERP domain filter, it will be written as:
ie, domain = ['|', ('field1','=',5),('field2','=',10)]
or domain = ['|', ('field1','=',field3),('field1','=',field3)]
Multiple Condition
Simple condition in programming:
if field1 = 5 or (field2 ! = 10 and field3 = 12)
In OpenERP domain filter, it will be written as:
domain = ['|',('field1','=',5),('&',('field2','!=',10),('field3','=','12'))]
Also this post from Vivek will be helpful to all. Cheers!!
Hi there, thank you for the explanation. Can you help me to understand this domain filter for contracts: [('employee_id.user_id', 'in', [usr.id for usr in user.user_ids])] Thank you in advance.
I can't understand that s*** sorry! Help needed!
['&', '|',
('product_id','=',product_id),
'&',
('product_tmpl_id.product_variant_ids','=',product_id),
('product_id','=',False),
('type', '=', 'normal')]
This is part of Odoo 10 mrp_production_view.xml...
Hi Muhammad, that code can be interpreted as:
(('product_id','=',product_id) or (('product_tmpl_id.product_variant_ids','=',product_id) and ('product_id','=',False))) and ('type', '=', 'normal')
keep in mind the order of parentheses.
HI, thenk you for the explanation.
Can you help me, i want to do the filtering with a simple condition but using a value of the function type field
see the codegerant_structure_id = fields.Integer('Structure id', compute='_getStructureIdForCurrentUser')
@api.one
def _getStructureIdForCurrentUser(self):
structure_id = self.env['afya.structure.sante'].search([('gerant_id', '=', self.env.uid )]).id
self.gerant_structure_id = structure_id
view ...
<record model="ir.actions.act_window" id="compte_wallet_list_action">
<field name="name">Compte_Wallet</field>
<field name="domain">[('structure_sante_id', '=', gerant_structure_id)]</field>
<field name="res_model">afya.compte.wallet</field>
<field name="view_mode">tree</field>
</record>
I'm looking for some insight about a tiny detail:
Regarding this definition
domain = ['|',('field1','=',5),('&',('field2','!=',10),('field3','=','12'))]
what's/why the difference between the lack of quotes like in 5 or 10 values and and the quoted one like in '12' ?
Thanks
The coder may declared the fields3 as string fields and other 2 fields as integer
