Odoo Development Tutorial: A Comprehensive Guide321

Introduction

Odoo is an open-source enterprise resource planning (ERP) and customer relationship management (CRM) software. It is designed to be modular and extensible, allowing businesses to tailor it to their specific needs. Odoo is used by over 4 million companies worldwide, and its popularity is growing rapidly. This tutorial will provide you with the basic knowledge and skills you need to develop Odoo applications.

Prerequisites

Before you can begin developing Odoo applications, you will need to install Odoo and create a database. You can download Odoo from the official website (/). Once you have installed Odoo, you can create a database by following the instructions in the Odoo documentation (/documentation/14.0/getting_started/). You may also find it helpful to have some general knowledge of Python.

Creating a New Module

The first step in developing an Odoo application is to create a new module. A module is a collection of Python code and XML files that define the functionality of your application. To create a new module, open the Odoo command line interface (CLI) and type the following command:```
odoo create-module my_module
```

This will create a new directory for your module in the Odoo modules directory. The directory will contain a number of files, including a `` file and a `my_module` directory.

The `` file is a Python file that defines the metadata for your module. It specifies the name of your module, the author, the version, and the dependencies. The `my_module` directory contains the Python code and XML files for your module.

Defining a Model

A model is a Python class that defines the data structure of an Odoo object. To create a new model, create a new Python file in the `my_module` directory. The file should have the same name as your model class. For example, if you want to create a model for a product, you would create a file called ``. The following code defines a simple model for a product:```
from odoo import models, fields
class Product():
_name = ''
name = ('Name', required=True)
price = ('Price', required=True)
```

The `_name` attribute specifies the name of the model. The `name` and `price` attributes specify the fields of the model. The `name` field is a character field that stores the name of the product. The `price` field is a float field that stores the price of the product.

Creating a Form View

A form view is an XML file that defines the layout of a form for an Odoo object. To create a new form view, create a new XML file in the `my_module/views` directory. The file should have the same name as your model class, but with a `.xml` extension. For example, if you want to create a form view for the `product` model, you would create a file called ``. The following code defines a simple form view for the `product` model:```








```

The `id` attribute specifies the unique identifier of the form view. The `model` attribute specifies the name of the model for which the form view is defined. The `field` elements specify the fields of the model that are displayed in the form view.

Creating a Tree View

A tree view is an XML file that defines the layout of a tree view for an Odoo object. To create a new tree view, create a new XML file in the `my_module/views` directory. The file should have the same name as your model class, but with a `` extension. For example, if you want to create a tree view for the `product` model, you would create a file called ``. The following code defines a simple tree view for the `product` model:```








```

The `id` attribute specifies the unique identifier of the tree view. The `model` attribute specifies the name of the model for which the tree view is defined. The `field` elements specify the fields of the model that are displayed in the tree view.

Installing Your Module

Once you have created your module, you can install it in Odoo by following the instructions in the Odoo documentation (/documentation/14.0/howtos/). You can also use the Odoo CLI to install your module by typing the following command:```
odoo install my_module
```

This will install your module in the Odoo database. You can now access your module by going to the Apps menu in Odoo.

Conclusion

This tutorial has provided you with the basic knowledge and skills you need to develop Odoo applications. For more information, please refer to the Odoo documentation (/documentation/).
