Understanding the Odoo Data Model
Before we dive into the process of creating a new product on Odoo using Python, let's take a moment to understand the underlying data model. Odoo follows a modular structure, where different modules are responsible for specific functionalities.
In the context of product management, Odoo provides the product module, which handles all aspects related to products, including their attributes, variants, pricing, and inventory management. To interact with the product module programmatically, we'll utilize the Odoo Python API, which allows us to access and manipulate data within the system.
Products and Product Templates
In Odoo, products are organized under the concept of “Product Templates.” A product template serves as a blueprint for creating individual product variants. It contains common attributes shared among the variants, such as the product name, description, pricing, and image. Each product template can have one or more product variants associated with it.
Product Attributes and Variants
Product attributes define the characteristics of a product. They can include attributes like size, color, material, or any other distinguishing feature that differentiates one product variant from another. These attributes can be used to create product variants with different combinations.
For example, let's say we have a T-shirt product template. The T-shirt can have attributes like size (small, medium, large), color (red, blue, green), and material (cotton, polyester). By combining these attributes, we can generate various product variants, such as a small red cotton T-shirt or a large blue polyester T-shirt.
Pricing and Inventory Management
Odoo also provides robust features for managing product pricing and inventory. Each product variant can have its own pricing rules, including list price, cost price, sale price, and discounts. Additionally, Odoo offers inventory management capabilities to track stock levels, set reordering rules, and manage warehouse locations.
Now that we have a basic understanding of the Odoo data model and how products are structured, let's move on to the next section where we'll start exploring the process of creating a new product programmatically using Python.
Setting up the Odoo Development Environment
Before we jump into coding, we need to set up our development environment to ensure a smooth workflow. Follow the steps below to get started:
Step 1: Install Odoo
To begin, we need to install Odoo on our local machine. Visit the official Odoo website (https://www.odoo.com) and navigate to the Downloads page. Choose the appropriate version for your operating system and follow the installation instructions provided. Odoo is compatible with Windows, macOS, and Linux.
Step 2: Create a New Odoo Module
To organize our custom code and modifications, we'll create a new Odoo module. Modules are self-contained units that encapsulate specific functionalities in Odoo. Open your terminal or command prompt and navigate to the Odoo addons directory.
cd <path_to_odoo_addons_directory>Code language: Bash (bash)Inside the addons directory, create a new directory for your module. Give it a meaningful name related to the purpose of the module. For example, if we're creating a module for managing a new product, we can name it product_customizations.
mkdir product_customizationsNavigate into the newly created module directory.
cd product_customizationsStep 3: Create the Module Manifest File
Every Odoo module requires a manifest file that describes its properties and dependencies. Create a new file called __manifest__.py inside the module directory using a text editor.
touch __manifest__.pyCode language: CSS (css)Open the __manifest__.py file and add the following content:
{ 'name': 'Product Customizations', 'version': '1.0', 'summary': 'Customizations for managing new products', 'author': 'Your Name', 'category': 'Custom Development', 'depends': ['product'], 'data': [ # Add your XML or CSV data files here (if any) ], 'installable': True, 'auto_install': False, 'application': False,}Code language: JSON / JSON with Comments (json)In the manifest file, provide the necessary information about your module, such as its name, version, summary, author, category, and dependencies. The depends key specifies that our module depends on the product module, as we'll be extending its functionality.
Step 4: Start Coding
Now that our module is set up, we can start writing the code to create a new product. Open your favorite Python editor or integrated development environment (IDE) and navigate to the module directory.
cd <path_to_odoo_addons_directory>/product_customizationsCode language: HTML, XML (xml)Create a new Python file called models.py inside the module directory.
touch models.pyCode language: CSS (css)Open the models.py file and begin coding the logic to create a new product using the Odoo Python API. We'll import the necessary Odoo classes and define a new class that inherits from the models.Model class.
from odoo import models, fields, apiclass ProductCustomization(models.Model): _inherit = 'product.template' # Add your custom fields and methods hereCode language: Python (python)Step 5: Test and Apply Changes
Save the models.py file and restart the Odoo server to apply the changes. Open your web browser and access the Odoo instance. Go to the Apps menu and click on the “Update Apps List” button. Search for your module name, “Product Customizations,” and install it.
Once the module is installed, you can navigate to the product management area in Odoo and observe the changes you made. Now you have the foundation to create new products
Adding Fields and Functionality to the New Product
In this section, we will enhance our custom module by adding additional fields and functionality to the new product. Follow the steps below to extend the product model and make it more feature-rich:
Step 1: Add Custom Fields
To provide more flexibility and customization options for our new product, we can add custom fields to capture specific information. Open the models.py file in your module directory.
from odoo import models, fields, apiclass ProductCustomization(models.Model): _inherit = 'product.template' # Add custom fields custom_field = fields.Char(string='Custom Field')Code language: Python (python)In the above code snippet, we added a new field called custom_field of type Char to hold custom information related to the product. You can choose the appropriate field type based on your requirements.
Step 2: Modify Existing Fields
In addition to adding custom fields, we can also modify existing fields to better suit our needs. Let's say we want to change the display format of the list_price field to show the currency symbol.
from odoo import models, fields, apiclass ProductCustomization(models.Model): _inherit = 'product.template' # Modify existing fields list_price = fields.Monetary(currency_field='company_currency_id', string='Sale Price') @api.depends('list_price') def _compute_sale_price(self): for product in self: product.sale_price = product.list_price sale_price = fields.Monetary(currency_field='company_currency_id', compute='_compute_sale_price', string='Sale Price', store=True)Code language: Python (python)In the code above, we changed the display label of the list_price field to “Sale Price” and added a computed field sale_price to store the same value as the list_price field.
Step 3: Implement Custom Functionality
To add more functionality to our new product, we can define custom methods within the ProductCustomization class. Let's create a method to calculate the discounted price based on a given percentage.
from odoo import models, fields, apiclass ProductCustomization(models.Model): _inherit = 'product.template' # Add custom fields and methods custom_field = fields.Char(string='Custom Field') @api.depends('list_price', 'discount') def _compute_discounted_price(self): for product in self: product.discounted_price = product.list_price * (1 - product.discount / 100) discount = fields.Float(string='Discount (%)', default=0.0) discounted_price = fields.Monetary(currency_field='company_currency_id', compute='_compute_discounted_price', string='Discounted Price', store=True) def apply_discount(self): for product in self: product.list_price = product.list_price * (1 - product.discount / 100)Code language: Python (python)In the code above, we added a new field discount to capture the discount percentage, and a computed field discounted_price to calculate the discounted price based on the list_price and discount fields. We also created a method apply_discount() to apply the discount to the product's list price.
Step 4: Update the Module Manifest
Remember to update the __manifest__.py file to include the new fields and methods:
{ 'name': 'Product Customizations', 'version': '1.0', 'summary': 'Customizations for managing new products', 'author': 'Your Name', 'category': 'Custom Development', 'depends': ['product'], 'Code language: JSON / JSON with Comments (json)Testing and Deploying the Custom Product Module
Once we have implemented the necessary changes and added new functionality to our custom product module, it's time to test it and deploy it to a live Odoo instance. Follow the steps below to test and deploy your custom module:
Step 1: Testing Locally
Before deploying the module to a production environment, it's crucial to thoroughly test it locally to ensure everything works as expected. To test the module, follow these steps:
- Start the Odoo server and launch the Odoo instance.

- Search for your module name, “Product Customizations,” and install it.
- Create a new product and verify that the custom fields and functionality are working correctly.
- Perform comprehensive testing by creating multiple products, applying discounts, and validating the results.
Step 2: Packaging the Module
Once you're confident that your module is working correctly, it's time to package it for deployment. To create a module package, follow these steps:
- In the root directory of your custom module, create a new directory named
product_customizations. - Copy all the module files into the
product_customizationsdirectory. - Zip the
product_customizationsdirectory, ensuring that all module files are included. - The resulting zip file is the module package ready for deployment.
Step 3: Deploying to a Live Odoo Instance
To deploy your custom module to a live Odoo instance, follow these steps:
- Log in to your Odoo instance as an administrator.
- Navigate to the Apps menu and click on the “Update Apps List” button.
