Hello,
It is due to wrong relation with the model
Try with this:
requisiciones_ids = fields.Many2many(
    'purchase.requisition',
    'reporteador_requisition_rel',
    'wizard_id',
    'requisition_id',
    string='Requisiciones'
)

Hope it helps..

Codesphere Tech

What is the target model name like sale.order, purchase.order etc.?

Codesphere Tech

Can you please check dependency in manifest file and also ensure that the purchase.requisition is installed in your database?

Leonardo Javier Preciado Herrera
Author

if i write in the manifest from purchase

'depends': ['account', 'purchase_requisition'],

in the update module disappears and cant update

and in my data base yes it is the table and the model we have a lot of requisition captured

iwant in my wizard slect some requisitions and printed in an excel file that's all i need to do a compartive of prices from all purchases ordres form that reqisitions that uses selects

Codesphere Tech

So the issue I understand is that if you don't put the purchase_requisition model and trying to declare m2m field for that and upgrade the module, you faced a key error, righ?
And if you add the model in dependency then you can't able to see your custom module, right?
Please confirm these things...

Leonardo Javier Preciado Herrera

if i add the model in dependency

when i reset the service from odoo and i want to upgrade the module the upgrade option dissapear

Leonardo Javier Preciado Herrera
Author

in this wizard i have project, respartner, and i dont have added any dependency i don know only this module of purchase_requisition is giving me headache it is wiched!!!

Codesphere Tech

Have you confirmed that your custom module is successfully installed? or can you provide the screenshot of the traceback if it is possible?

Leonardo Javier Preciado Herrera

i dont understand what is a traceback?

Codesphere Tech

Copy whole error which you have faced in Odoo.

Hi,


The error "psycopg2.ProgrammingError: no existe la relación «_unknown»" when creating a many2many relationship in Odoo usually means the database table you're trying to access doesn't exist or isn't accessible. This can happen due to an incorrect model name, a missing or incorrectly created many2many relational table, database synchronization issues after module updates, or insufficient user permissions.

To fix this, first, ensure the model name in your Many2many field definition is absolutely correct and matches the _name attribute of the target model. Then, update your module to apply the changes to the database. If the issue persists, check if the relational table has been created correctly in the database. If not, try manually updating the database schema using the command line. Finally, verify that the user has the necessary access rights to both models involved in the relationship.

the target is purchase_requisition

i change

requisiciones_ids = fields.Many2many(
'purchase.requisition',
'reporteador_requisition_rel',
'wizard_id',
'requisition_id',
string='Requisiciones'
)

and pops KeyError: 'purchase.requisition'

i change for :

requisiciones_ids = fields.Many2many(
'purchase_requisition.purchase.requisition',
'reporteador_requisition_rel',
'wizard_id',
'requisition_id',
string='Requisiciones'
)

and pops same error psycopg2.ProgrammingError: no existe la relación «_unknown»
