Your first module - Odoo 11.0


This chapter helps you to create your first Odoo module and deploy it in your project.

This tutorial requires you created a project on, and you know your Github repository's URL.

Basic use of Git and Github is explained.

The below assumptions are made:

  • ~/src is the directory where are located the Git repositories related to your Odoo projects,
  • odoo is the Github user,
  • odoo-addons is the Github repository,
  • feature-1 is the name of a development branch,
  • master is the name of the production branch,
  • my_module is the name of the module.

Replace these by the values of your choice.

Create the development branch

Clone your Github repository on your machine:

$ mkdir ~/src
$ cd ~/src
$ git clone
$ cd ~/src/odoo-addons

Create a new branch:

$ git checkout -b feature-1 master

Create the module structure

Scaffolding the module

While not necessary, scaffolding avoids the tedium of setting the basic Odoo module structure. It nevertheless requires odoo-bin, and therefore the installation of Odoo on your machine.

If you do not want to bother installing Odoo on your machine, you can also [UNKNOWN NODE download_reference] in which you replace every occurrences of my_module to the name of your choice.

Use odoo-bin scaffold to generate the module structure in your repository:

$ ./odoo-bin scaffold my_module ~/src/odoo-addons/

This will generate the below structure:

├── controllers
│   ├──
│   └──
├── demo
│   └── demo.xml
├── models
│   ├──
│   └──
├── security
│   └── ir.model.access.csv
└── views
    ├── templates.xml
    └── views.xml

Uncomment the content of the files:

  • models/, an example of model with its fields,
  • views/views.xml, a tree and a form view, with the menus opening them,
  • demo/demo.xml, demo records for the above example model,
  • controllers/, an example of controller implementing some routes,
  • views/templates.xml, two example qweb views used by the above controller routes,
  •, the manifest of your module, including for instance its title, description and data files to load. You just need to uncomment the access control list data file:

    # 'security/ir.model.access.csv',


If you want to create your module structure manually, you can follow Build an Odoo module to understand the structure of a module and the content of each file.

Push the development branch

Stage the changes to be committed

$ git add my_module

Commit your changes

$ git commit -m "My first module"

Push your changes to your remote repository

$ git push -u origin feature-1

You need to specify -u origin feature-1 for the first push only. From that point, to push your future changes, you can simply use

$ git push

Test your module

Your branch should appear in your development branches in your project.

In the branches view of your project, you can click on your branch name in the left navigation panel to access its history.

You can see here the changes you just pushed, including the comment you set. Once the database ready, you can access it by clicking the Connect button.

If your project is configured to install your module automatically, you will directly see it amongst the database apps. Otherwise, it will be available in the apps to install.

You can then play around with your module, create new records and test your features and buttons.

Test with the production data

You need to have a production database for this step. You can create it if you do not have it yet.

Once you tested your module in a development build with the demo data and believe it is ready, you can test it with the production data using a staging branch.

You can either:

  • Make your development branch a staging branch, by drag and dropping it onto the staging section title.

  • Merge it in an existing staging branch, by drag and dropping it onto the given staging branch.

You can also use the git merge command to merge your branches.

This will create a new staging build, which will duplicate the production database and make it run using a server updated with your latest changes of your branch.

Once the database ready, you can access it using the Connect button.

Install your module

Your module will not be installed automatically, you have to install it from the apps menu. Indeed, the purpose of the staging build is to test the behavior of your changes as it would be on your production, and on your production you would not like your module to be installed automatically, but on demand.

Your module may not appear directly in your apps to install either, you need to update your apps list first:

  • activate the developer mode from the Settings,

  • in the apps menu, click the Update Apps List button,
  • in the dialog that appears, click the Update button.

Your module will then appear in the list of available apps.

Deploy in production

Once you tested your module in a staging branch with your production data, and believe it is ready for production, you can merge your branch in the production branch.

Drag and drop your staging branch on the production branch.

You can also use the git merge command to merge your branches.

This will merge the latest changes of your staging branch in the production branch, and update your production server with these latest changes.

Once the database ready, you can access it using the Connect button.

Install your module

Your module will not be installed automatically, you have to install it manually as explained in the above section about installing your module in staging databases.

Add a change

This section explains how to add a change in your module by adding a new field in a model and deploy it.

In your module, edit the file models/

$ nano ~/src/odoo-addons/my_module/models/

We encourage you to use the editor of your choice, such as Atom, Sublime Text, PyCharm, instead of nano.

Then, after the description field

description = fields.Text()

Add a datetime field

start_datetime = fields.Datetime('Start time', default=lambda self:

Then, edit the file views/views.xml

$ nano ~/src/odoo-addons/my_module/views/views.xml


<field name="value2"/>


<field name="start_datetime"/>

These changes alter the database structure by adding a column in a table, and modify a view stored in database.

In order to be applied in existing databases, such as your production database, these changes requires the module to be updated.

If you would like the update to be performed automatically by the platform when you push your changes, increase your module version in its manifest.

Edit the module manifest

$ nano ~/src/odoo-addons/my_module/


'version': '0.1',


'version': '0.2',

The platform will detect the change of version and trigger the update of the module upon the new revision deployment.

Stage your changes to be committed

$ cd ~/src/odoo-addons/
$ git add my_module

Commit your changes

$ git commit -m "[ADD] my_module: add the start_datetime field to the model my_module.my_module"

Push your changes

$ git push

The platform will then create a new build for the branch feature-1.

Once you tested your changes, you can merge your changes in the production branch, for instance by drag-and-dropping the branch on the production branch in the interface. As you increased the module version in the manifest, the platform will update the module automatically and your new field will be directly available. Otherwise you can manually update the module within the apps list.

Use an external Python library

If you would like to use an external Python library which is not installed by default, you can define a requirements.txt file listing the external libraries your modules depends on.

The platform will use this file to automatically install the Python libraries your project needs.

The feature is explained in this section by using the Unidecode library in your module.

Create a file requirements.txt in the root folder of your repository

$ nano ~/src/odoo-addons/requirements.txt



Then use the library in your module, for instance to remove any special characters in the name field of your model.

Edit the file models/

$ nano ~/src/odoo-addons/my_module/models/


from odoo import models, fields, api


from unidecode import unidecode


start_datetime = fields.Datetime('Start time', default=lambda self:


def create(self, values):
    if 'name' in values:
        values['name'] = unidecode(values['name'])
    return super(my_module, self).create(values)

def write(self, values):
    if 'name' in values:
        values['name'] = unidecode(values['name'])
    return super(my_module, self).write(values)

Adding a Python dependency requires a module version increase for the platform to install it.

Edit the module manifest

$ nano ~/src/odoo-addons/my_module/


'version': '0.2',


'version': '0.3',

Then stage, commit and push your changes

$ git add requirements.txt
$ git add my_module
$ git commit -m "[IMP] my_module: automatically remove special chars in my_module.my_module name field"
$ git push
