I am working on student registration module. I want to to auto generate registration code and save it into database where as computed method having some issue.
1.. can't save Computed result in database.
2.. when i use store attribute with field and depends api then there is not increment in variable.
here is my code below.
reg_code = fields.Char(compute='code', string='Code', readonly=True)
#api.multi
def get_code(self):
count = 0
reg = "Reg #"
for record in self:
count += 1
record.reg_code = reg + " " + str(count)
if record.reg_code:
count += 1
record.reg_code = reg+" "+str(count)
else:
count += 1
record.reg_code = reg+" "+str(count)
You can use sequence in Odoo.
find sequence in
Enable Active developer mode
Settings --> Sequence
Then add this code in your module:
change field as
reg_code = fields.Char(string='Code',required=True, copy=False, readonly=True, index=True, default= lambda self: self.env['ir.sequence'].next_by_code('student.registration'))
Create another xml file like if you want to create sequence by code.
shipping_sequence.xml
and add this code
<?xml version="1.0" encoding="utf-8"?>
<odoo>
<data noupdate="1">
<!-- Sequences for student.registration -->
<record id="seq_student_registration" model="ir.sequence">
<field name="name">Student Registration</field>
<field name="code">student.registration</field>
<field name="prefix">Code-</field>
<field name="padding">1</field>
<field name="company_id" eval="False"/>
</record>
</data>
</odoo>

I need to create a button which will define a ticket the value of the state variable to cloturé.
And when a ticket is cloturé, it will on read only.
How can i do it ?
The ticket's model is helpdesk.ticket
view.xml :
<?xml version='1.0' encoding='UTF-8'?>
<odoo>
<record id="helpdesk_ticket_view_form_inherit_header_modifie" model="ir.ui.view">
<field name="name">helpdesk.ticket.modifie.header</field>
<field name="model">helpdesk.ticket</field>
<field name="inherit_id" ref="helpdesk_fsm.helpdesk_ticket_view_form" />
<field name="arch" type="xml">
<xpath expr="//button[#name='action_generate_fsm_task']" position="attributes" >
<attribute name="string">Planifier tache</attribute>
</xpath>
</field>
</record>
</odoo>
ticket.py :
# -*- coding: utf-8 -*-
from odoo import models, fields, api
class ticket_inherit(models.Model):
_inherit = "helpdesk.ticket"
state = fields.Selection(['test','annulé','cloturé'],'selection')
#What i want to do
def cloture_le_ticket(self):
state = 'cloturé'
You can just use write().
state = fields.Selection(string="State", selection=[
('test', 'Test),
('annulé', 'Annulé'),
('cloturé', 'Cloturé')
])
def cloture_le_ticket(self):
self.write({
'state': 'cloturé'
})
To force the ticket to be read-only:
def write(self, vals):
for record in self:
if record.state == 'cloturé':
raise exceptions.UserError("Sorry but the ticket is read only")
return super(HelpdeskTicket, self).write(vals)
So I'm making this localization kind of module for Lebanon and am currently doing the location bit.
The intended functionality is to have the choices of governate, district and region restrict the choices the user can make by filtering out the irrelevant options.
Here are the models:
# -*- coding: utf-8 -*-
from odoo import models, fields, api
# Base model
class LebaneseLocation(models.Model):
_inherit = "res.partner"
governate_id = fields.Many2one("lebanon.governate", "Governate")
district_id = fields.Many2one("lebanon.district", "District")
region_id = fields.Many2one("lebanon.region", "Region")
# Child models with the necessary relations
class Governate(models.Model):
_name = "lebanon.governate"
name = fields.Char()
child_districts = fields.One2many("lebanon.district", "parent_governate",
"Child Districts")
class District(models.Model):
_name = "lebanon.district"
name = fields.Char()
parent_governate = fields.Many2one("lebanon.governate", "Parent Governate")
child_regions = fields.One2many("lebanon.region", "parent_district",
"Child Regions")
class Region(models.Model):
_name = "lebanon.region"
name = fields.Char()
parent_district = fields.Many2one("lebanon.district", "Parent District")
and the view file:
<?xml version="1.0"?>
<odoo>
<record id="view_res_partner_extended_location" model="ir.ui.view">
<field name="name">Contacts Custom</field>
<field name="model">res.partner</field>
<field name="inherit_id" ref="base.view_partner_form"/>
<field name="arch" type="xml">
<field name="category_id" position="after">
<field name="governate_id" domain="[('child_districts','=?','district_id'),('child_districts.child_regions','=?','region_id')]"/>
<field name="district_id"/>
<field name="region_id"/>
</field>
</field>
</record>
</odoo>
And all the data was inputed via two data files, one makes the records without relations and the other updates the same records with relations.
I was testing things out with the Governate domain and it just kept returning nothing.
Is there some way to check what exactly these parameters i'm evaluating are returning? That would help a lot with debugging.
Edit: Here's a screenshot from Studio's menu for the domain, in case that's at all relevant for debugging (I avoid Studio like a plague usually)
Domain Image
I solved my issue by forgoing the XML approach and setting the domains using the onchange api call:
#api.onchange('governate_id', 'district_id', 'region_id')
def update_domains(self):
governate = self.governate_id.name
district = self.district_id.name
region = self.region_id.name
result = {}
result['domain']={
'governate_id':[('child_districts.name','=?', governate),
('child_districts.child_regions.name', '=?', region)],
'district_id':[('parent_governate.name', '=?', governate),
('child_regions.name', '=?', region)],
'region_id':[('parent_district.name', '=?', district),
('parent_district.parent_governate.name', '=?', governate)]
}
return result
Hi guys Help me with this.
the check field doesnt increment.it stays blank
from odoo import api, fields, models, _
class check_print(models.Model):
_inherit = 'account.payment'
check = fields.Char("Check Number",readonly=True)
#api.model
def create(self,vals):
if vals.get('payment_method_code') == ('check_printing'):
vals['check'] = self.env['ir.sequence'].next_by_code('seq.ch.code')
res = super(check_print, self).create(vals)
return res
<?xml version="1.0" encoding="utf-8"?>
<odoo>
<data noupdate="1">
<record id="seq_check_id" model="ir.sequence">
<field name="name">check</field>
<field name="code">seq.ch.code</field>
<field name="prefix">CH</field>
<field name="padding">10</field>
<field name="company_id" eval="False"/>
</record>
</data>
</odoo>
the check field is empty everytime i save the record
Seems that this line is not being evaluated to True:
if vals.get('payment_method_code') == ('check_printing'):
Also check your indentation of this lines that need to be outside the if block
res = super(check_print, self).create(vals)
return res
I have a model(modelA) with one2many field related to another model(modelB) and one of the fields in modelB is a category field, which is a many2one field. The requirement is to have a one2many field displayed for each category. So if there are 2 categories named 'category1' and 'category2', the form view of modelA should have 2 one2many fields, one which displays records of having category1 and another for category2(which could possibly done using domain).
For eg modelA and modelB has the following structure.
class classA(models.Model):
_name = 'modelA'
modelA_one2manyfield = fields.One2many('modelB', 'modelB_many2onefield')
class classB(models.Model):
_name = 'modelB'
name = fields.Char()
category = fields.Many2one('modelC')
modelB_many2onefield = fields.Many2one('modelA')
How would i go about implementing a form view for modelA so that for each category(which can be added by the user, hence there can be of any number of categories) there is a seperate one2many field.
What you are asking take a lot of time to give a very good answer one of the way that i think you need to try is override the fields_view_get because this is the method that retreive the view and here you can change the arch field to add a costum field take a look at this tutorial :
Tutorial for dynamic view
but i think you will have a problem, because even when you put the domain on the one2many field in XML, odoo will not filter
the record when the loading happen on the view :
<!-- here all record are shown but the expected behavior is the one2many should be empty -->
<field name="one2many_field_name" readonly="1" nolabel="1" domain="[('id', '=', False)]">
but when i add this field to the python declaration
# here no record will be shown on the view and that's what was expected
one2many_field_name = fields.One2many(..., domain=[('id', '=', False)])
so the question adding one2many field to arch via fields_view_get is easy but the problem is filtring data !!
It's technically not possible. Because you can't have 2 times the same field in the same view.
But you can create a specific widget to showing what you want. How you can see in the timesheet view (My Current timesheet menu).
This is a little tutorial to created a widget.

i found out that you can create field using ORM method even compute field. i think creating a widget is better but good to know that wen can create costum fields .
Hope this helps you
Note i didn't create a menu for person record but you can see the view by clicking on the owner_id in the car form if the new one2many field not shown just refresh the page.
Need to store default value on qty in M.sqr and square meter like quantity on hand showing default entered value.
when i click on update button of quantity on Hand from product inventory page
then it should show me a previous entered value.
class stock_change_product_qty(osv.osv):
_inherit = 'stock.change.product.qty'
_columns = {
'new_quantity' : fields.float('Qty in Boxes'),
'squ_meter': fields.related('product_id','squ_meter', type='float', relation='product.product', string='Square Meter'),
'qty_char': fields.float('Qty in M.sqr', compute='_compute_qty_char'),
}
#api.depends('new_quantity', 'squ_meter')
def _compute_qty_char(self):
for record in self:
record.qty_char = record.new_quantity * record.squ_meter
view.xml
<field name="name">update_product_quantity inherit</field>
<field name="model">stock.change.product.qty</field>
<field name="inherit_id" ref="stock.view_change_product_quantity"/>
<field name="arch" type="xml">
<xpath expr="//field[#name='new_quantity']" position="attributes">
<attribute name="string">Qty in Boxes</attribute>
</xpath>
<xpath expr="//field[#name='new_quantity']" position="replace">
<field name="new_quantity"/>
<field name="squ_meter"/>
<field name="qty_char"/>
</xpath>
</field>
</record>
A solution is to use a function as default value for your field:
odoo V8
from openerp import api, fields, models
class stock_change_product_qty(models.Model):
_inherit = 'stock.change.product.qty'
new_quantity = fields.Float(string='Qty in Boxes', default=1.0),
squ_meter = fields.Float(related='product_id.squ_meter', string='Square Meter', default=1.0),
qty_char = fields.Float('Qty in M.sqr', compute='_compute_qty_char'),
}
#api.one
#api.depends('new_quantity', 'squ_meter')
def _compute_qty_char(self):
for record in self:
record.qty_char = record.new_quantity * record.squ_meter
odoo V7
def _your_function(self, cr, uid, context=None):
your code here
...
...
...
return field_value
_defaults = {
'your_field' : _your_function,
}
#api.onchange
This decorator will trigger the call to the decorated function if any of the fields specified in the decorator is changed in the form:
#api.onchange('fieldx')
def do_stuff(self):
if self.fieldx == x:
self.fieldy = 'toto'
In previous sample self corresponds to the record currently edited on the form. When in on_change context all work is done in the cache. So you can alter RecordSet inside your function without being worried about altering database. That’s the main difference with #api.depends
At function return, differences between the cache and the RecordSet will be returned to the form.
