Resolving the Model not found Error in Odoo 12: A Guide for Beginners

When working with Odoo, you may occasionally run into errors that can be frustrating, especially if you’re just starting out. One common issue is when you encounter the message Model not found after upgrading your module. This error typically indicates that Odoo is unable to find the model you've defined in your custom module. If you've built a custom hospital module and received this error, you are not alone. In this guide, we will walk you through the problem and provide a clear solution.

The Problem: ‘Model not found’ Error

Here’s a brief overview of the error you might encounter when trying to upgrade your module:

This message suggests that Odoo cannot find the model rumahsakit.poli, which you have likely defined in your custom module. There are a few reasons this could happen, especially if you’re new to Odoo development. The root cause often relates to how Odoo loads its modules and where your files are positioned.

Analyzing Your Code

Let’s examine the key elements of your code to better understand what to look for:

Model Definition

For the model, you might have written something like this:

View Definition

You may also have defined the view in an XML file. Make sure it looks similar to this:

The Solution: Properly Structuring Your Module

1. Verify Model and View Placement

One of the first things to check is the location of your model and view files. For Odoo to properly recognize them, both should reside in the same module, defined in your manifest file (__manifest__.py).

Ensure your model and its corresponding view are in the same directory and included in the manifest.

2. Check Import Order

Odoo loads modules in a specific order. If the view file is defined before the model is loaded, it will trigger the Model not found error.

To test whether your model is imported correctly, add a debug print statement at the top of your model file:

This print statement will help you to confirm whether the model is being loaded when the module is initialized.

3. Update the Manifest File

Ensure that your __manifest__.py file includes both the model file and the view file in the data list:

4. Testing Your Module Again

After making these adjustments, attempt to upgrade your module again:

Use the command line or Odoo UI to update the module.

Encountering the Model not found error in Odoo 12 can be daunting, especially for newcomers. However, by following the simple steps outlined above, you can resolve this issue and continue developing your custom modules with confidence. Remember to check the placement and import order of your files, and you’ll be on the right track!

Happy Coding!
