I have 2 modules let's call them module_a and the module_b
and i want to use m2o relationships between these 2 models but for both sides and here is the sample code that shows what i am trying to do is
module_a/models/model_a.py
from odoo import models, fields, api
class module_a(models.Model):
_name = 'module_a.module_a'
_description = 'module_a.module_a'
name = fields.Char()
value = fields.Integer()
value2 = fields.Float(compute="_value_pc", store=True)
description = fields.Text()
module_b_id = fields.Many2one('module_b.module_b')
@api.depends('value')
def _value_pc(self):
for record in self:
record.value2 = float(record.value) / 100
module_a/__manifest__.py
{
'name': "module_a",
'summary': "Short (1 phrase/line) summary of the module's purpose",
'description': """
Long description of module's purpose
""",
'author': "My Company",
'website': "https://www.yourcompany.com",
'category': 'Uncategorized',
'version': '0.1',
'depends': ['base'],
'data': [
'security/ir.model.access.csv',
'views/views.xml',
],
}
this is the module_b
module_a/models/model_b.py
from odoo import models, fields, api
class module_b(models.Model):
_name = 'module_b.module_b'
_description = 'module_b.module_b'
name = fields.Char()
value = fields.Integer()
value2 = fields.Float(compute="_value_pc", store=True)
description = fields.Text()
module_a_id = fields.Many2one('module_a.module_a')
module_a_value = fields.Integer(compute='_compute_module_a_id_value')
@api.depends('value')
def _value_pc(self):
for record in self:
record.value2 = float(record.value) / 100
@api.depends('module_a_id')
def _compute_module_a_id_value(self):
for rec in self:
rec.module_a_value =rec.module_a_id.value if rec.module_a_id else False
module_b/__manifest__.py
{
'name': "module_b",
'summary': "Short (1 phrase/line) summary of the module's purpose",
'description': """

In case , I have used the related field also instead of using the compute to get value to the model_a_id_value and it is also not working , also I put the module_b as a depends in module_a , it also throw the keyerror as this and i think it cause of the circular dependencies ,
KeyError: 'module_b.module_b'
so what should i do ? is there are fix for this ?
I want to use m2o relationships with module_a and module_b for both sides ?
