I am getting this error after adding a binary filed I remover the filed but getting the same error
Table name 'n_hesaby_subscription_manager_subscription_manager_res_users_rel' is too long
odoo.exceptions.ValidationError: ("Table name 'n_hesaby_subscription_manager_subscription_manager_res_users_rel' is too long", None) - - -
does anyone know what it means, I can't find it
From the look of the table name it's created from a many2many field between n_hesaby_subscription_manager_subscription_manager and res.users when you don't provide a name for the relation table Odoo will generate it for you model_1_name_model_2_name_rel.
So in your many2many definition specify a shorter name
m2m_field_name = fields.Many2many(comodel_name='res.users',
relation='put_nice_table_name_here',
column1='put_nice_and_short_field_name_here_to',
column2='user_id',
string='You field label')
I'm using my phone sorry for my short answer I hope you get the idea, you can check Odoo standard modules you will find planty of examples.
Always specify the name of the relation in your many2many field is a good practice prevent unexpected behavior.

i want to set default value in many2many field for example:
that field in models.py:
# alarms
alarm_ids = fields.Many2many(
'calendar.alarm', 'calendar_alarm_calendar_event_rel',
string='Reminders', ondelete="restrict",
help="Notifications sent to all attendees to remind of the meeting.")
also it is default values created by system, and i want first variant by default:
i know that i can set it by id, but dont know how.
You can use Command to set X2many field values.
From the documentation:
Via Python, we encourage developers craft new commands via the various functions of this namespace. We also encourage developers to use the command identifier constant names when comparing the 1st element of existing commands.
Example:
from odoo import Command, models, fields
class CalendarEvent(models.Model):
_inherit = 'calendar.event'
alarm_ids = fields.Many2many(default=lambda self: [Command.link(self.env.ref('calendar.alarm_notif_1').id)])
i just watch in postgres, there is no id`s like in xml screenshots, i just take id of a record and find some documentation.
next example works:
in odoo you can get value of field by it's str name:
exm:
name = getattr(self, 'name')
what i want now is to know the type of field name is it :
fields.Char, fields.Many2one, fields.Many2many .....
so what i need is something like this
gettype(self, 'user_id')
is there a way to now what is the type of field in odoo?
You can search from ir.model.fields model.
ir_model_obj=self.env['ir.model.fields']
ir_model_field=ir_model_obj.search([('model','=',model),('name','=',field)])
field_type=ir_model_field.ttype
if field_type=='many2one':
print "do operation"
This may help you.
Odoo provides this information in the _fields attribute, I think It's better because every thing happens In the Python side no need for contacting the database, especially In my case my model have more than 30 fields :
for name, field in self._fields.iteritems():
if not isinstance(field, (fields.Many2one, fields.Many2many, fields.One2many)):
# logic go here
If you you want to verify just one fields:
if not isinstance(self._fields[field_name], (fields.Many2one, ...)): # do something
I am trying to create a new field on the sale.order.line model. This field is called x_all_route_ids, and is meant to contain all of the available stock.location.route for an Order Line.
It should look up the product_id.route_ids and product_id.routes_from_categ_ids for the Order Line, and join them together into a single set of Routes.
I am trying to set this field up through the Odoo UI, but getting error related to my "Dependencies".
I have Dependencies defined as:
product_id, product_id.route_ids, product_id.routes_from_categ_ids
I have Compute defined as:
for record in self:
record['x_all_route_ids'] = record.product_id.route_ids
To start I am just trying to get the field to show the same value as product_id.route_ids, but it's not working. When I save, I get the following error:
Error while validating constraint
Unknown field u'product_id' in dependency u'product_id'
Any idea what I'm doing wrong here?
I was able to get this working. I think the issue was just a bug in the UI that came about because I had been trying so many different things. After refreshing the page, the following worked:
Dependency = product_id
Field type = many2many
Compute method:
for record in self:
full = record.product_id.route_ids | record.product_id.route_from_categ_ids
record['x_all_route_ids'] = full.filtered('sale_selectable')
I have a field in the XML file, categ_id. I need to access the value of that field in my Python code, in product_template class. I tried vals as a paremeter but it did not work.
If you can give me an example object.field_name as it relates to the case I have described.
Nebojsa - your question is not understandable at all, but I'll try to answer it. You can get the value of categ_id in two or even three ways:
vals.get('categ_id') - this is the way to go when you are creating a new record or updating existing one with change in categ_id field - otherwise you'll get an error or NoneType defined.
template = self.pool.get('product.template).browse(cr, uid, ids) and then template.categ_id.id - to get the value when you do have an id of the record, so you can ask database of value stored or in transaction, if there were any changes.
third opition is the dirtiest one, because it is just cr.execute("SELECT categ_id FROM product_template WHERE id = %s", (ids[0],)) and then category_id = cr.fetchall() - it is not always good option to use that, as it asks for records already existing in database (not counting these in transaction)
I have been struggling with this, i have two models and showing data in Cgridview with one model, this model contains some id's whose values are in different table
So, i have added
'value'=> 'TblAreaoflaw::model()->FindByPk($data->typeoflaw)->areaoflaw'
which is giving this error
"Trying to get property of non-object"
Might be due to this reason that the some records doesn't exist in the TblAreaoflaw. Can't we check in this line through isset?
When i put static value, it work well, like
'value'=> 'TblAreaoflaw::model()->FindByPk(5)->areaoflaw',
Could anyone please help
thanks a lot
The error you get is because this expression TblAreaoflaw::model()->FindByPk($data->typeoflaw) is returning null. This means that you are effectively trying to get null->areaoflaw which won't work (this is what the error message "Trying to get property of non-object" clarifies).
My best guess is that $data->typeoflaw returns a non-existing primary key for the TblAreaoflaw model.
Make sure :
TblAreaoflaw is actually a model, I doubt its Areaoflaw
You have database specified primary key which is the id (5) you are passing
Try:
'value'=> '(TblAreaoflaw::model()->FindByPk($data->typeoflaw)->areaoflaw) ?
: "default or null value"'
Obviously substitute the null string to whatever you want. You may need to adjust the condition to use !empty() or similar, but see how it goes. (And if you do that or aren't using PHP 5.3, use the full ternary expression.)
