Using an Odoo nightly repository, you will be able to install and upgrade Odoo with the help of your traditional package manager (apt or yum). For those who enjoy the Docker project, officials docker images for Odoo 14, 15 and 16 are provided on Docker Hub. They are not nightly builds per se, but we keep these images updated on a regular basis.

The basic CRUD operations can be extended to implement specific business logic. For example, the create() and write() model methods might implement guiding cost principles default values or some other automation. Other code methods can be added to enforce validation rules or automatically compute field values.

At this stage, we’ve effectively parsed out our Odoo To-do App, which means we need to dive into the ins and outs of the Odoo developer tools before hitting the gas on the actual implementation. While we will rarely use SQL to interact directly with the database engine, it’s important to note that it is possible to do so and might be necessary in particular cases. Conducting business at the pace and complexity of today’s world often comes with some amount of logistical strain across the gamut of your operations.

• Developer mode can be used for both small modifications (such as adding a custom field) and larger customizations (such as creating an application with its own menus, views and underlying data model).
• A website framework is also available to use as a public front end for external users.
• If you plan to run the PostgreSQL cluster on the same host than the Odoo one, install PostgreSQL before.
• The server API used by the official web client is the same as the one available to any other application.

Note that the General Settings menu option is only visible when there is at least one app installed. In such a case, simply install one app, like Contacts, CRM, or any other of your preference in order to activate the menu. As a best practice, always test changes on a copy database before doing them in a live system. If things go wrong, there is a chance that an upgrade of the affected app, or the base module, can resolve them, but this is not an assured solution.

Before doubling back to the to-do project, let’s quickly move through a pragmatic overview of the layers involved in Odoo architecture and the role of each component we’ll use. But first, we need to start thinking about the layers involved in our application. The model names in py file and xml are different as mentioned below.

Odoo relies on its object relational mapping (ORM) engine as the interface between the apps and the database. The ORM provides the application programming interface (API) used by the addon modules to interact with the data. For example, the Partner data entity, used for data records like customers or suppliers, is represented by a model.

The To-do Items model should include the Work Team field to select a list of people. Part of the project will be to limit the people that can be selected to be part of Work Teams, which can be executed by modifying the Partner model to add an Is Work Team? Odoo’s extensible architecture allows a large number of freelancers and organizations to develop Odoo Apps or Modules and place them in the marketplace for sale or to be downloaded for free. The main Odoo components are the framework, about 30 core applications (also called official modules), and thousands of community modules.

Implementing a simple to-do app in Odoo

The web client supports all the features needed by a business application, such as login sessions, navigation menus, data lists, and forms. Odoo is able to relieve some of this strain by providing a rapid application framework well-suited for building approachable and efficient business applications. A website framework is also available to use as a public front end for external users. Equipped with CMS features, a framework allows us to create both static and dynamic web pages. The website framework uses controller components for the code implementing the presentation-specific logic, keeping it separate from the model’s intrinsic logic.

The source code for the OpenObject framework and the core ERP modules are provided by Belgium-based Odoo S.A. Both the Odoo Enterprise Edition and the Odoo SaaS offer the Odoo Studio App, an interactive application builder. We won’t be using it here, since it is not available for the Odoo Community Edition used as reference for this series of articles. Finally, for the presentation tier, we will add the Menu option for our application, as well as the Views for the To-do Item model. The essential views for a business application are the List view (to browse the existing records), and the Form view (to zoom in to a record and see all the details).

As a teaching tool, the developer mode features act as a way to introduce how the application configuration data is organized in the Odoo framework, and how the developer mode can be leveraged for simple customizations or prototyping solutions. The Community version is libre software, licensed under the GNU LGPLv3. The Enterprise version has proprietary extra features and services. The source code for the framework and core ERP modules is curated by the Belgium-based Odoo S.A. Odoo is available for both on-premises and ready to use SaaS environment.

The client software uses remote procedure calls (RPCs) to the Odoo service, running the ORM and the business logic. ORM API calls are sent to the Odoo server for processing, to read, write, verify, or perform any other action. As previously noted, our specification for the app includes a Work Team feature, i.e., the ability to select a list of people that will be working on the task. This is where Odoo’s Partner model, technical name res.partner, comes into play for individual people, companies, and addresses. One special aspect under the presentation tier is that Odoo provides a web client out of the box.

This set of articles intends to spread basic knowledge about Odoo development in hopes of providing the Odoo community with more autonomy when it comes to building better business applications. The business logic tier will be the basic create, read, update, delete (CRUD) operations handled by the web framework, with no additional automation requirements to support. We’ll use Python code in developer modules to access the full power of the framework.

The developer mode is useful to inspect and modify current Odoo configurations. It allows us to customize Odoo apps directly from the UI, making for a convenient way to implement changes and add features. Developer mode can be used for both small modifications (such as adding a custom field) and larger customizations (such as creating an application with its own menus, views and underlying data model). The Odoo server API is open, with all server functions available through it. The server API used by the official web client is the same as the one available to any other application.
