Learn the basics of using Python in Odoo, a powerful and customizable open-source business management software.
This tutorial is perfect for beginners looking to improve their coding skills and understanding of Odoo's functionalities.
Are you interested in learning how to develop business applications using Python? If so, then Odoo is the perfect tool for you. Odoo is an open-source enterprise resource planning (ERP) software that is built using Python. In this tutorial, we will guide you through the basics of Odoo development using Python.
Setting up your development environment
Before we dive into developing with Odoo, we need to set up our development environment. The first step is to install Odoo on your local machine. You can do this by following the installation instructions on the Odoo website. Once you have Odoo installed, you can start creating your first Odoo module.
Creating your first Odoo module
To create a new module in Odoo, you need to create a new directory in the addons folder of your Odoo installation. Inside this directory, create a new Python file with the following code:
from odoo import models, fields
class Product(models.Model):
_name = 'my_module.product'
name = fields.Char('Name')
description = fields.Text('Description')
Save this file and restart your Odoo server. Now, if you go to the Odoo dashboard, you should see a new menu item called ‘Products.’ Click on this menu item to view your newly created module.
Working with models and fields
In Odoo, models are used to define the data structure for your application. Each model represents a table in the database. In the example above, we created a new model called ‘Product’ with two fields: ‘name’ and ‘description.’ The ‘name’ field is of type Char, while the ‘description’ field is of type Text.
To add new fields to your model, simply add new fields to the class definition. For example, if you want to add a price field to the Product model, you can add the following code:
price = fields.Float('Price')
Now, restart your Odoo server, and you should see the new ‘Price’ field in the Product form.
Creating views
Views are used to create the user interface for your application. In Odoo, views are defined using XML. To create a new view for the Product model, create a new XML file in the views folder of your module directory. Here is an example of a simple form view for the Product model:
Save this file and restart your Odoo server. Now, if you go back to the Odoo dashboard and click on the ‘Products’ menu item, you should see a new ‘Create’ button that allows you to create new products with the fields ‘name,’ ‘description,’ and ‘price.’
Adding business logic
In addition to defining models and views, you can also add business logic to your Odoo module. This is done by creating new Python methods on your model classes. For example, let’s say you want to calculate the total price of a product based on the quantity and price. You can add a new method to the Product model like this:
from odoo import models, fields, api
class Product(models.Model):
_name = 'my_module.product'
name = fields.Char('Name')
description = fields.Text('Description')
price = fields.Float('Price')
@api.multi
def calculate_total_price(self, quantity):
self.total_price = self.price * quantity
total_price = fields.Float('Total Price')
Save this file and restart your Odoo server. Now, if you go back to the Product form in the Odoo dashboard, you should see a new field called ‘Total Price.’ If you enter a quantity and click on the ‘Calculate’ button, the total price will be calculated based on the quantity and price of the product.
Conclusion
In this tutorial, we covered the basics of Odoo development using Python. We learned how to create a new module, define models and fields, create views, and add business logic to our application. This is just the tip of the iceberg when it comes to Odoo development, but it should give you a good starting point to start building your own business applications with Odoo.
If you are interested in learning more about Odoo development, there are plenty of resources available online, including the official Odoo documentation and community forums. With a little bit of practice and experimentation, you will be well on your way to becoming an expert Odoo developer. Happy coding!
