Fix “Model Not Found” Error in Odoo 12 – Simple Steps

If you are encountering the “Model not found” issue in Odoo 12, it means that Odoo is unable to locate or load a specific model that you’re trying to use. This can happen due to several reasons, and here are the possible steps to troubleshoot and resolve the issue:

1. Check if the Model is Defined

Ensure that the model is correctly defined in the models.py file of your Odoo module. The basic structure for defining a model in Odoo looks like this:

from odoo import models, fields

class MyModel(models.Model):
    _name = 'my.model'  # Ensure the model name is correct
    _description = 'Description of my model'

    name = fields.Char(string="Name")

Ensure the _name field is set properly and the module has been loaded.

2. Ensure the Module is Installed

If the module containing the model is not installed or not properly loaded, Odoo won’t be able to find the model. To fix this:

• Go to Apps in Odoo.
• Search for your custom module.
• Install or update the module if necessary.

3. Check Model Name in Code

The model’s name used in the code should match exactly what is defined in your model. For instance, if you’re using the model in XML files or other Python code, ensure the correct name is used:

<record id="action_my_model" model="ir.actions.act_window">
    <field name="res_model">my.model</field>  <!-- Make sure this matches the model name in models.py -->
</record>

4. Module Not Loaded Properly

Sometimes the module might not have loaded properly, especially if it was manually added. Try the following steps:

• Restart the Odoo service: Odoo loads models when it starts, so restarting Odoo can sometimes fix this issue:

  sudo service odoo restart

• Update your module: Run the following command in your terminal to update the module:

  ./odoo-bin -u your_module_name

5. Check for Model Inheritance

If your model extends another model (via inheritance), make sure the parent model exists and is loaded before your custom model. For example:

class InheritedModel(models.Model):
    _inherit = 'base.model'

Ensure that the parent model (base.model) is available.

6. Database Issues

Sometimes a database might not be synced properly with the models defined in code. To resolve this:

• Update the module from the UI: Go to Apps in Odoo, search for your module, and click on the Update button.
• Run a database upgrade:

  ./odoo-bin -d your_db_name -u your_module_name

7. Check for Dependencies

Ensure all dependencies for the module (both in terms of Python packages and other Odoo modules) are installed. If a dependency is missing, the model might not load properly.

• Check the __manifest__.py file to see if all required modules are listed in the depends section.

  'depends': ['base', 'mail', 'other_module'],

8. Check Odoo Logs

The Odoo server logs often provide useful details when models fail to load. Check the logs to see if there are any errors related to your model:

tail -f /var/log/odoo/odoo.log

Look for errors related to your module or model name.
