Hi,
I tried installing the free Hotel Management app (by Cybrosys) on Odoo18 Community Edition (with all dependencies met) on request of one of my clients. However, I got the following error, saying the following - looking for the category_id:

Occured on mycompany.com on model ir.module.module and id 12 on 2025-02-27 16:38:43 GMT

Traceback (most recent call last):

How can I correct this?

Thank you

Hi do you know which model that called this 'category_id'. Can you try to print the name of the comodel and see if you have other modules that trigger this.

I think you can trace it this way. I don't have enough clues if only based on this error log to help you.

base on your error it seems like category_id is not updating in your databse table, you should find the category_id field and fix the required changes.

like wise you can specify more on the error in details.

Hi Andry,
at the start of the error message, it says "on model ir.module.module and id 146 ir.module.module and id 146"

Is that sufficient?


My python skills are almost zero :-( but with directions, I'd probably cope

Thanks Andry,

I added it this way:
"def setup_nonrelated(self, model):

        super(One2many, self).setup_nonrelated(model)

        if self.inverse_name:

            # link self to its inverse field and vice-versa

            comodel = model.env[self.comodel_name]

            print('>>>>>>>', comodel._name) 

invf = comodel._fields[self.inverse_name]

            if isinstance(invf, (Many2one, Many2oneReference)):

                # setting one2many fields only invalidates many2one inverses;

                # integer inverses (res_model/res_id pairs) are not supported

                model.pool.field_inverses.add(self, invf)

            comodel.pool.field_inverses.add(invf, self)"

but then got a 503 error. I also added the print line on the same line starting with invf = comodel._fields...

same error. :-(


So, I installed in (in the meantime) on another fresh Odoo 18 install - same system, same everything. I could install the 3rd party Hotel Management App without issue, BUT as soon as I installed another app (CRM), I got the same error - no installation possible.

I guess that means that the Cybrosys Hotel Management App is not coded to work alongside other apps... a pity 

Thanks for your help though, appreciate it!

Hi Fritz, it's not really informative.

Do you have any technical experience with Python? you can try to print the comodel as I mentioned and you will know which model/table that caused the problem.

Andry Ang

That's fine haha, but do you have other experiences?
Like debugging the codes? if yes, you can direct yourself to

This file "/usr/lib/python3/dist-packages/odoo/fields.py", line 4585, in setup_nonrelated
and check on this line of code
invf = comodel._fields[self.inverse_name]
before this, you can add
print('>>>>>>>', comodel._name)

Andry Ang

If it's too hard for you to follow,
I would suggest you to just create new DB and install the module once.

See if the problem still existed.
