Odoo 14 Development Cookbook

Chapter 2: Managing Odoo Server Instances

In Chapter 1, Installing the Odoo Development Environment, we looked at how to set up an Odoo instance using only the standard core add-ons that are shipped with source. This chapter focuses on adding non-core or custom add-ons to an Odoo instance. In Odoo, you can load add-ons from multiple directories. In addition, it is recommended that you load your third-party add-ons or your own custom add-ons from separate folders to avoid conflicts with Odoo core modules. Even Odoo Enterprise Edition is a type of add-on directory, and you need to load this just like a normal add-ons directory.

In this chapter, we will cover the following recipes:

  • Configuring the add-ons path
  • Standardizing your instance directory layout
  • Installing and upgrading local add-on modules
  • Installing add-on modules from GitHub
  • Applying changes to add-ons
  • Applying and trying proposed pull requests

    About the terminology

    In this book, we will use the...

Configuring the add-ons path

With the help of the addons_path parameter, you can load your own add-on modules into Odoo. When Odoo initializes a new database, it will search for add-on modules within directories that have been provided in the addons_path configuration parameter. Odoo will search in these directories for the potential add-on module.

Directories listed in addons_path are expected to contain subdirectories, each of which is an add-on module. Following initialization of the database, you will be able to install modules that are given in these directories.

Getting ready

This recipe assumes that you have an instance ready with a configuration file generated, as described in the Storing the instance configuration in a file recipe in Chapter 1, Installing the Odoo Development Environment. Note that the source code of Odoo is available in ~/odoo-dev/odoo, and the configuration file in ~/odoo-dev/myodoo.cfg.

How to do it…

To add the ~/odoo-dev/local-addons...

Standardizing your instance directory layout

We recommend that your development and production environments all use a similar directory layout. This standardization will prove helpful when you have to perform maintenance operations, and it will also ease your day-to-day work.

This recipe creates a directory structure that groups files with similar life cycles or similar purposes in standardized subdirectories.

Note

This recipe is only useful if you want to manage similar folder structure development and production environments. If you do not want this, you can skip this recipe.

Also, it is not compulsory to observe the same folder structure as in this recipe. Feel free to alter this structure to suit your needs.

How to do it…

To create the proposed instance layout, you need to perform the following steps:

  1. Create one directory per instance:
    $ mkdir ~/odoo-dev/projectname
    $ cd ~/odoo-dev/projectname
  2. Create a Python virtualenv object in a subdirectory called env/:
    $ python3 -m venv env
  3. Create some subdirectories, as follows:
    $ mkdir src local bin filestore logs

    The functions of the subdirectories are as follows:

    • src/: This contains the clone of Odoo itself, as well as the various third-party add-on projects (we have added Odoo source code to the next step in this recipe).
    • local/: This is used to save your instance-specific add-ons.
    • bin/: This includes various helper executable shell scripts.
    • filestore/: This is used as a file store.
    • logs/ (optional): This is used to store the server log files.
  4. Clone Odoo and install the requirements (refer to Chapter 1, Installing the Odoo Development Environment, for details on this):
    $ git clone -b 14.0 --single-branch --depth 1 https://github...

How it works…

We generate a clean directory structure with clearly labeled directories and dedicated roles. We are using different directories to store the following:

  • The code maintained by other people (in src/)
  • The local-specific code
  • filestore of the instance

By having one virtualenv environment per project, we are sure that the project's dependencies will not interfere with the dependencies of other projects that may be running a different version of Odoo or will use different third-party add-on modules, which require different versions of Python dependencies. This comes at the cost of a little disk space.

In a similar way, by using separate clones of Odoo and third-party add-on modules for our different projects, we are able to let each of these evolve independently and only install updates on the instances that need them, hence reducing the risk of introducing regressions.

The bin/odoo script allows us to run the server without having...

Installing and upgrading local add-on modules

The core functionality of Odoo comes from its add-on modules. You have a wealth of add-ons available as part of Odoo itself, as well as add-on modules that you can download from the app store or that have been written by yourself.

In this recipe, we will demonstrate how to install and upgrade add-on modules through the web interface and from the command line.

The main benefits of using the command line for these operations include being able to act on more than one add-on at a time and having a clear view of the server logs as the installation or update progresses, which is very useful when in development mode or when scripting the installation of an instance.

Getting ready

Make sure that you have a running Odoo instance with its database initialized and the add-ons path properly set. In this recipe, we will install/upgrade a few add-on modules.

How to do it…

There are two possible methods to install or update add...

Installing add-on modules from GitHub

GitHub is a great source of third-party add-ons. A lot of Odoo partners use GitHub to share the add-ons they maintain internally, and the Odoo Community Association (OCA) collectively maintains several hundred add-ons on GitHub. Before you start writing your own add-on, ensure that you check that nothing already exists that you can use as is or as a starting point.

This recipe will show you how to clone the partner-contact project of the OCA from GitHub and make the add-on modules it contains available in your instance.

Getting ready

Suppose you want to add new fields to the customers (partner) form. By default, the Odoo customers model doesn't have a gender field. If you want to add a gender field, you need to create a new module. Fortunately, someone on a mailing list tells you about the partner_contact_gender add-on module, which is maintained by the OCA as part of the partner-contact project.

The paths that are used in this...

Applying changes to add-ons

Most add-ons that are available on GitHub are subject to change and do not follow the rules that Odoo enforces for its stable release. They may receive bug fixes or enhancements, including issues or feature requests that you have submitted, and these changes may introduce database schema changes or updates in the data files and views. This recipe explains how to install the updated versions.

Getting ready

Suppose you reported an issue with partner_contact_gender and received a notification that the issue was solved in the last revision of the 14.0 branch of the partner-contact project. In this case, you will want to update your instance with this latest version.

How to do it…

To apply a source modification to your add-on from GitHub, you need to perform the following steps:

  1. Stop the instance using that add-on.
  2. Make a backup if it is a production instance (refer to the Manage Odoo server databases recipe in Chapter 1, Installing...

Applying and trying proposed pull requests

In the GitHub world, a Pull Request (PR) is a request that's made by a developer so that the maintainers of a project can include some new developments. Such a PR may contain a bug fix or a new feature. These requests are reviewed and tested before being pulled into the main branch.

This recipe explains how to apply a PR to your Odoo project in order to test an improvement or a bug fix.

Getting ready

As in the previous recipe, suppose you reported an issue with partner_address_street3 and received a notification that the issue was solved in a PR, which hasn't been merged in the 14.0 branch of the project. The developer asks you to validate the fix in PR #123. You need to update a test instance with this branch.

You should not try out such branches directly on a production database, so first create a test environment with a copy of the production database (refer to Chapter 1, Installing the Odoo Development Environment...

What I liked:Scope - the technical topics covered are the ones most developers will want to know about.Detail - lots of explanatory text and examples.Examples - you can develop your own module and access a GitHub repository to check your workAuthors - Daniel, Holger and Alexandre are well known and long time Community members so you are hearing from expertsWhat I didn't:Terms - some are not explained until AFTER they are introduced and this might trip up less knowledgeable DevOps folksWhy - the why behind the best practices isn't always explained - some may find this leaves them needing to research a topic in more detail on their ownScreenshots - when covering Backend Views there could be a lot more to convey how these workMobile - basically not coveredUp to Date - multi_edit is not covered (new at v14) so readers might want to review other resources to check they are fully up to date with what is available in this version.Still highly recommend the book!

There is an obvious shortage of books on CRM systems. This is sad, because in our days the CRM market has been experiencing shocks and new players are emerging. In particular, there is a lack of books devoted to Odoo, so for example Odoo 13 was left without attention of major publishers. For this reason, the release of a new book is already an event.I have been waiting for this book for a long time and with impatience. As expected, it contains a lot of useful information. The quality of the selection of the material shows that the authors are practicing professionals and shared the solution to those issues that they themselves faced. The book is full of healthy recipes.Below I will write what thoughts I had while studying the book:Good thing there is a section on sitemaps.In section 9 - Backend views, it would be nice to add more illustrations of how the various views looks. This would help to choose the right one. For example, fig. 9.3 was a revelation for me, I did not know that this could be done.I was especially pleased with the recipe for redirecting old URLs. This must be paid attention to if you are creating a site on Odoo instead of an existing one, in order to exclude a failure in SEO.Another interesting recipe is "Generating videos / screenshots for failed test cases". Such an idea would not have occurred to me!The section on performance optimization is qute interesting. Basically, Odoo is fast enough even on weak machines. Before I used to use Nginx tools to further speed up Odoo.My wishes for the publishing house:Unfortunately, in the electronic version of the book, tables are presented as images. The problem is search doesn't work inside images and it can be difficult to find what readers needs.Another problem of the electronic version is that sometimes you come across unnecessary spaces in the command lines (for example, page 62), so you need to be careful when copying them from the book.Overall, the book is certainly useful and I will keep the book handy in my daily work.Who should I recommend this book to - someone who already knows the basics of working in Odoo. For beginners, I would advise you to wait until "Odoo 14 Development Essentials" is released. Cookbooks are not intended for beginners, they are a collection of recipes for solving practical problems. Moreover, it is intended specifically for developers. If you only use standard functionality, then much of the valuable information in this book will not be so useful to you.I look forward to the release of Odoo 14 Development Essentials.Thanks to Pack publishing for regularly publishing books about Odoo.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter.
