Odoo Debug Extension: A Comprehensive Guide to Debugging

A crucial step in the software development process is debugging, particularly when working with intricate programs like Odoo. With the help of the Odoo Debug extension, developers can efficiently troubleshoot and debug their applications. This post will discuss the Odoo Debug Extension, explain how to activate and utilize it, and offer some useful code samples for debugging Odoo apps.

What is the Odoo Debug Extension?

By giving developers access to debug information straight from the Odoo interface, the Odoo Debug extension is a feature integrated into the Odoo environment that aids in problem diagnosis and troubleshooting. It makes possible functions that are necessary for debugging Odoo apps, like logging, model inspection, and developer tool access.

You can quickly and effectively gain additional insight into your code using the Odoo Debug extension, which will help you identify faults early and address problems more quickly.

Key Features of the Odoo Debug Extension

Debug Mode: By activating debug mode, you can get additional information about the model, fields, views, and technical data, which is otherwise hidden.
View and Model Inspection: By exposing secret fields or characteristics, the plugin enables you to examine the views and models, assisting developers in comprehending their behavior and structure.
Logging: You can track exceptions, keep an eye on how your code is doing, and gain important insights into how your system operates at runtime by turning on logging with the Odoo Debug extension.
Performance Monitoring: It allows you to monitor database queries and actions taken by the system to ensure that there are no unnecessary performance bottlenecks.
Error Messages: The Debug extension helps capture and display detailed error messages, so you can identify the root cause of any issues quickly.
Record ID Display: In debug mode, record IDs are displayed in the URL for easier reference.

How to Enable Debug Mode in Odoo?

Enabling debug mode is simple, and there are multiple ways to do so. Below are the most common methods to activate the debug mode:

1. Manually Add the Debug Parameter to the URL:

Navigate to your Odoo instance in your browser.
In the address bar, append ?debug to the URL.
Example:

arduino

http://your-odoo-instance.com/web?debug

2. Using the Odoo Interface:

Go to the Odoo “Settings” menu.
In the top-right corner, click on your user avatar, and you’ll see an option for “Activate Developer Mode” (sometimes displayed as “Activate Debugging”).
Click on this option to enable debug mode.

3. Using the Odoo Command Line:

If you’re using Odoo in development mode, you can also start Odoo in debug mode by using the --dev flag when running the Odoo server:

Debugging with Odoo’s Built-in Tools

Once you’ve activated the debug mode, several debugging tools will become available directly within the Odoo interface. Here’s an overview of the most common tools that are provided:

1. Inspecting Models and Fields:

In debug mode, you can inspect the fields of models directly from the UI. This is useful for inspecting technical details that are not visible in normal mode.
For instance, if you are looking at a form view, you can right-click on any field and select “Inspect.” This will reveal the technical details of that field, including its model and attributes.

2. Viewing the XML of Views:

You can also view the raw XML code of the views by clicking the “View XML” option.
This is especially useful for customizing or debugging the layout of Odoo views. It lets you see if the right view is being loaded for a particular model.

3. Logging and Error Tracking:

Odoo logs can be enabled from the debug tools for deeper insights. Any errors or exceptions will be logged into the server logs, which are especially helpful during troubleshooting.

4. Database Query Monitoring:

With debug mode on, Odoo will log SQL queries. You can track the queries made by Odoo to understand performance issues or debug data inconsistencies.

Code Examples for Debugging in Odoo

Let’s look at some common scenarios where the Odoo Debug Extension can help with debugging, along with examples of how you can leverage debugging techniques in your code.

Example 1: Debugging a Model’s `create` Method

Let’s assume you want to debug the behavior of the create method in one of your models. The create method is responsible for creating new records in the database. Here’s an example of how to add logging for debugging purposes:

What’s happening here?

We’re logging the input values (vals) before creating a record and also logging the newly created record’s ID after the creation is complete.
This will help you understand exactly what data is being passed to the create method and confirm that the record creation is happening as expected.

Example 2: Debugging a Custom Action in a Controller

Let’s consider a custom controller action in Odoo where you need to debug the flow of an HTTP request. Here’s an example:

python

from odoo import http

import logging

# Set up the logger
_logger = logging.getLogger(__name__)

class MyController(http.Controller):

@http.route(‘/my_controller/debug_example’, auth=‘public’)
def debug_example(self, **kwargs):
_logger.debug(f”Received request with parameters: {kwargs}“)
# Simulate some processing
result = {‘status’: ‘success’, ‘message’: ‘Debugging example worked!’}
_logger.debug(f”Returning result: {result}“)
return http.Response(str(result))

What’s happening here?

We log the incoming parameters (kwargs) received in the request and the result being returned.
This is particularly useful when you’re dealing with complex web routes and need to debug issues related to how requests are processed.

Example 3: Debugging a Scheduled Action (Cron Job)

If you want to debug a scheduled action (a cron job) in Odoo, you can use logging within the cron job method to track its execution.

What’s happening here?

The logger helps track when the scheduled action starts, performs, and finishes.
This can be crucial in debugging cron job execution and monitoring tasks that are scheduled to run automatically.

Conclusion

An indispensable tool for developers working with Odoo apps is the Odoo Debug plugin. You may improve your Odoo apps, find faults early, and speed up your development process by turning on debug mode and using the integrated debugging tools and methodologies.

To enhance your development process, you may use the Odoo Debug extension to monitor performance, examine models and views, and incorporate appropriate logging. You can become proficient in Odoo debugging and make sure your application functions properly by following the steps and examples described in this article.
