I'm not a expert but i create a tiny modules before now i'm getting this error, i have been development other models of this same module without error after two weeks, i'm asking help because I cannot find the error.

When I install the module the first time on clean database, i can create a record, but next times or if i uninstall and reinstall i cannot.

This is the error i got:

RPC_ERROR

Hi!

Could you check that you have added the necessary depends to your __manifest__.py? It is similar as you didn't add the dependency to the "product" module that contains the "product.template" model.

"depends": ["product"],
As a suggestion, the relation field name would be more clearer if it will have the suffix "_id" for Many2one fields and "_ids" for Many2many or One2many fields. As recommended in Odoo Developer Guidelines: https://www.odoo.com/documentation/14.0/developer/misc/other/guidelines.html?highlight=developer guideline#symbols-and-conventions

Please check your manifest file, file must have depends on the specified models (models used in many2one)

'depends': ['base', 'account', 'logimpex'],

I had the same error and I found a misspelling in comdel_name in the inverse_name field in the line model, I was writing the definition of the field "field_id = fields.Many2one(comdel_name='" and it should be written comodel_name, so that error was raised, when I fixed this misspelling the error go away.

I hope this may help someone,

Thanks

Javier Agustin Vescio

Hi. In my case, I was getting the same error. It was because I had one many2one with underscore for the model name. For example, I had somehting like this:

`Many2one('project_task', ...)` Wrong

The correct way is with a dot, like this:

`Many2one('project.task', ...)` Good

Hi Alfonso,

Did you find the problem because i'm facing the same and i could not find the solution!?

Vincent

jdossougoin@gmail.com

Great ! Thanks for your answer. It helps me.

Alejandro Fredes

Hi! I had the same issue and I resolved it by checking my o2m/m2o relations. I thought I wrote everything right but I made a typing error when writing the comodel's name.

I don't see all the custom models you have but I think you can check if all your m2o/o2m relations are ok.

Pavel

I had the same problem putting a Many2one with the 'account.asset' model and the problem was that it had to depend on account_asset and not on account, because account_asset was where the 'account.asset' model was.

Hussein Kadweka

I personally had the same error too and the problem is either your one2many or many2one or many2many fields.......its likely you have misspelt the relation model

The other scenario is either your module depends on another module that you haven't added it to depends
