how can i retrieve the value of a many2one field or its ID from another model
for exemple:
class Contrat(models.Model):
_name = 'facturation.contrat'
contrat_parent_id = fields.Many2one('facturation.contrat', string='Numéro Contrat Client',
domain=[('is_prestataire', '=', False)])
class Lot(models.Model):
contrat_id = fields.Many2one('facturation.contrat', ondelete='cascade')
articlecontrat_ids = fields.Many2many('facturation.articleouvrage',string='Article Lot')
91/5000
i want that when i change contrat_parent_id i get it back to use it and filter my articles for field 'articlecontrat_ids'
here you need to use onchange event i'm assuming that facturation.articleouvrage have a m2o field named contrat_id
# in onchange event always put the name of the field that trigger the event
#api.onchange('contrat_parent_id ')
def onchange_contrat(self):
"""update the domain when we change the contrat"""
if self.contrat_parent_id :
# always check if the field is not empty
# return the domain like this but i don't know what you need exactly
return {'domain': {'articlecontrat_ids ' : [('contrat_id ', '=', self.contrat_parent_id.contract.id)]}}
else: # remove the domain
return {'domain': {'articlecontrat_ids ' : []}}
if you want to remove all records when user change the contrat_id but i think you make the user ungry
to reselect all this records.
self.articlecontrat_ids = [(5, 0, 0)]

I want to get id from url when i click the button.
This is URL, id is 69:
http://localhost:8069/web#id=69&cids=1&menu_id=385&action=507&model=inventory.menu&view_type=form
I need to get this id in many2one field.
This is my wizard py file:
from odoo import api,fields,models
class ReduceInventoryWizard(models.TransientModel):
_name = "reduce.inventory.wizard"
_description = "Reduce Inventory Wizard"
inventory_ids = fields.Many2one('inventory.menu', string="Ürün Referans No: ", default=lambda self: self.env['inventory.menu'].search([('id', '=', 69)], limit=1))
As you can see, ('id', '=', 69) this is running but just one product. I want the information of that product to come automatically when I click the button in which product.
I tried this one: ('id', '=', self.id). But is not working.
In this situation there should be active_id or better active_ids in Odoo's context.
So you just can set the default parameter to use a default method, which will either return a value or an empty recordset:
def default_my_many2one_field_id(self):
active_ids = self.env.context.get("active_ids")
if active_ids:
return self.env["another.model"].browse(active_ids[0])
return self.env["another.model"]
my_many2one_field_id = fields.Many2one(
comodel_name="another.model", string="My M2o Field",
default=default_my_many2one_field_id)
So Im creating a hotel management module . I have the option to filter rooms based on bed_type and tag. Tag contains different facilities like AC, TV etc. So an user will come and select a bed_type and the facilities he wants and in the third field it should show the rooms that have the given configuration if not available an error messages should come. SO i created a onchange function to do this , but i dint know how to include the tags in it. Im doing it on odoo v14. m
This is the model for the room
from odoo import api, fields, models, _
class HotelRoom(models.Model):
_name = 'hotel.room'
_description = 'hotel room'
_rec_name = 'room_number'
room_number = fields.Char('Room Number', required=True)
room_rent = fields.Monetary('Room Rent')
tag = fields.Many2many('hotel.tags', string='Facilities')
dormitory_count = fields.Integer('Dormitory count')
bed_type = fields.Selection([
('single', 'Single'),
('double', 'Double'),
('dormitory', 'Dormitory')
], required=True, default='other')
This is the model for the reception
class HotelAccommodation(models.Model):
_name = 'accommodation.room'
_description = 'Reception'
bed_type = fields.Selection([
('single', 'Single'),
('double', 'Double'),
('dormitory', 'Dormitory')
], required=True, string= 'Bed type')
state = fields.Selection([
('draft','Draft'),
('check-in','Check-In'),
('check-out', "Check-Out"),
('cancel','Cancel'),
], required=True, default='draft', tracking=True)
tag = fields.Many2many('hotel.tags', string='Facilities')
room_id = fields.Many2one('hotel.room', string='Room')
Using this I can filter the rooms based on the bed_type but I need to have the tags as well.I tried giving it inside the domain but its not working .
#api.onchange('bed_type')
def filter_room(self):
for rec in self:
return {'domain': {'room_id': [('bed_type', '=', rec.bed_type)]}}
You need also to add the tag field to the domain and to the onchange decorator, so the method will be called when the tag field is modified.
The method is invoked on a pseudo-record that contains the values present in the form, you do not need to loop over self.
Try the following example:
#api.onchange('bed_type', 'tag')
def filter_room(self):
return {'domain': {'room_id': [('bed_type', '=', self.bed_type), ('tag', 'in', self.tag.ids)]}}
You can use _compute fields with the store option = True

In this image, there is a product search record that will search for name and default_code. I need to make it so that it will also look at my custom Many2Many field.
This is the field in the inherited model.
product_list = fields.Many2many("product.list", string="Product List")
The custom model only has _name, _description, and name variables.
The question is how to make the search to also look at all of the possible Many2Many data of this field.
I have tried this in the inherited model:
#api.model
def name_search(self, name='', args=None, operator='ilike', limit=100):
res = super(product_template_inherit, self).name_search(name='', args=None, operator='ilike', limit=100)
ids = self.search(args + [(name, 'in', 'product_list.name')], limit=limit)
if ids:
return ids.name_get()
return res
Nothing happens to the search. It still searches using the same behavior regardless of the code above.
Summary: I need to be able to search product by product list (custom Many2Many field inherited in the product.template model)
=============================================
UPDATE
Current code from what I have been trying is now this.
#api.model
def _name_search(self, name, args=None, operator='ilike', limit=100, name_get_uid=None):
args = args or []
if operator == 'ilike' and not (name or '').strip():
domain = []
else:
domain = ['|', ('name', 'ilike', name), ('product_list.name', 'ilike', name)]
product_ids = self._search(expression.AND([domain, args]), limit=limit, access_rights_uid=name_get_uid)
return self.browse(product_ids).name_get()
However, it looks like it still searches using the same old fields. It does not change to behave as my function is written.
You can compute the search domain then return the result of the _search method.
The fleet module already uses the same logic to search vehicles using the driver name, you have just to replace the driver_id with product_list:
class ProductProduct(models.Model):
_inherit = 'product.product'
#api.model
def _name_search(self, name, args=None, operator='ilike', limit=100, name_get_uid=None):
args = args or []
if operator == 'ilike' and not (name or '').strip():
domain = []
else:
domain = ['|', ('name', operator, name), ('product_list.name', operator, name)]
return self._search(expression.AND([domain, args]), limit=limit, access_rights_uid=name_get_uid)
I am adding custom One2many field in sale.order form view just below the sale.order.line.
I am computing values on_change it is displaying values but when I am going to save the sales order it is generating error that
ValueError: Wrong value for tax.lines.order_id: sale.order(24,)
Python:
class SaleOrderInherit(models.Model):
_inherit = ['sale.order']
tax_line = fields.One2many('tax.lines', 'order_id', states={'cancel': [('readonly', True)], 'done': [('readonly', True)]}, copy=True, auto_join=True)
#on.change('partner_id')
def calculating_tax(self):
//After some code
self.env['tax.lines'].create({
'tax_id': tax['tid'],
'name': tax['name'],
'amount': tax['tax'],
'order_id': self.id
})
class TaxLines(models.Model):
_name = 'tax.lines'
tax_id = fields.Char('Tax Id')
name = fields.Char('Tax Name')
amount = fields.Char('Tax Amount')
order_id = fields.Many2one('sale.order', string='Tax Report', ondelete='cascade', index=True, copy=False)
Because I am creating one2many field before creating the order.
But is there any way to get rid of this problem.
Edit:
Error after replacing my code with Charif DZ code:
Never create records in onchange events they are immidiatly saved in database what if the user decided to cancel the order, instead of create use new with create an object but doesn't save it in database.
def calculating_tax(self):
//After some code
# to add record to your o2m use `|` oprator
# if you want to clear record before start adding new records make sure to empty your field first by an empty record set like this
# self.tax_line = self.env['tax.lines'] do this before the for loop that is used to fill-up the field not put it inside or you will get only the last record
self.tax_line |= self.env['tax.lines'].new({
'tax_id': tax['tid'],
'name': tax['name'],
'amount': tax['tax'],
# 'order_id': self.id remove the many2one because it's handled automaticly by the one2many
})
I hope this help you good luck
I would like to have my selections depend on the value of a Char field, for instance, a Char field defined as such:
my_char = fields.Char("Enter Something", readonly = False)
so I suppose the selection field should call a function, something like "_get_value"
my_selection = fields.Selection(selection = ' _get_value')
#api.model
def _get_value(self):
my_list = [('key1','value1')]
#no idea how to assign the value of my_char to value1
return my_list
Eventually, I would like to have the selections in the drop down list vary as the user input different strings in my_char.
Is this achievable in Odoo? Because if it's not, I should better start reorganizing my structure. Thanks a lot.
As far is i know, it isn't possible with field type Selection. But you can use a Many2one field for such a behaviour.
class MySelectionModel(model.Models):
_name = "my.selection.model"
name = fields.Char()
class MyModel(models.Model):
_name = "my.model"
my_char = fields.Char()
my_selection_id = fields.Many2one(
comodel_name="my.selection.model", string="My Selection")
#api.onchange("my_char")
def onchange_my_char(self):
return {'domain': {'my_selection_id': [('name', 'ilike', self.my_char)]}}
Or without a onchange method:
my_selection_id = fields.Many2one(
comodel_name="my.selection.model", string="My Selection",
domain="[('name', 'ilike', my_char)]")
To let the Many2one field look like a selection, add the widget="selection" on that field in the form view.
How the domain should look like, should be decided by you. Here it is just an example.
No need to write method here. Just declare the dictionary to a variable and call it in selection field.
VAR_LIST = [('a','ABC'),
('p','PQR'),
('x','XYZ')]
my_selection = fields.Selection(string="Field Name",VAR_LIST)
