Odoo Development: Tree view with custom styles

Mon, 26 Sep 2022 09:13:47 +0200

The Odoo UI cannot be customized as easy as reports and websites. Using modules we can easily inject custom CSS styles.

Odoo Development: Show last updated date above list view

Wed, 08 Jun 2022 10:01:06 +0200

Odoo runs various reports in the background. Some of these report take a while to finish and therefore seeing the last updated date is important. In a few steps I will show how you can add the last updated date to a list view.

Odoo Development: Show message dialog

Tue, 01 Feb 2022 09:21:25 +0100

Some things are easily done in the Odoo framework, others are more difficult. An easy thing such as opening a dialog window with a custom message is more difficult than expected.

Odoo Development: Set attributes conditionally

Wed, 24 Nov 2021 14:06:11 +0100

Attributes such as invisible can be set on fields, widgets and buttons based on a condition. By using the attrs attribute the field and condition can be passed to the element. Here is an example: attrs="{'invisible': [('active', '=', True)]}".

But how do we achive this for tree elements where attrs is not available?

Ansible: Combine group and host vars

Mon, 25 Oct 2021 08:13:01 +0200

In Ansible the configuration parameters are usually separated into two categories: host and group vars. As their names say these are variables that are either applied to a specific host or a group of hosts. And here is already an edge case. What if we want to configure a variable for group, but then also give the possibility to modify for a specific host. Read on to see my solution.

Odoo Development: Group by related field

Wed, 29 Sep 2021 08:24:59 +0200

The Odoo ORM provides a read_group method. Calling this method and passing a domain definition, fieldnames and a groupby fieldname will return a domain recordset grouped by the fieldname. A big drawback is that you cannot pass a relation to a subfield. Importing the itertools library gives us new options to do so.

Odoo Development: Create a settings page

Tue, 14 Sep 2021 16:36:23 +0200

Odoo stores all module settings in the res.config.settings model. This model is based on the models.TransientModel class, which means that the settings data is not persisted with this model.

This is just nice to know. I will show how you can create a settings page for your Odoo module and let you know about its limitations.

Odoo Development: Enable multi edit

Tue, 14 Sep 2021 13:19:22 +0200

With Odoo 13 an new attribute was introduced to the tree view that enables editing multiple rows at once.

Odoo Development: Create a smart button with a counter

Thu, 26 Aug 2021 08:29:56 +0200

Smart buttons help navigating between linked models in Odoo. Creating a smart button requires three components: counter field, compute function, view action and a button box on the view.

Odoo Development: Prevent deletion with custom constraint

Mon, 26 Jul 2021 10:09:50 +0200

By default Odoo asks for confirmation if a record is being deleted. Making validations before deletion is up to the developer. I will show how you can add a custom constraint that prevents a record being deleted.

Odoo Development: Add archiving functionality

Mon, 26 Jul 2021 09:58:30 +0200

Odoo has a builtin archiving function for any model. Once a record is archived it will not be displayed in any views and selections, but can is easily be unarchived. This functionality ensures that relations must not be removed if linked records is obsolete.

Odoo Development: Configurable Kanban state

Wed, 14 Jul 2021 13:32:44 +0200

With the Odoo framework it is pretty easy to create a kanban view that groups and sorts an item by a state field. I’ll show how a kanban view can be added in a few steps.

Odoo Development: Add activity button

Wed, 14 Jul 2021 10:07:47 +0200

The activity button is part of the chatter. Every model form can have activities. I will show how you can enable the activity button for your model form using the mixin class.

Tue, 06 Nov 2018 12:11:01 +0200

At AdNovum we are running GoCD for automating the continuous delivery (CD) of our software products. GoCD has become the de facto standard for running CD pipelines.

In this post I will give you a short introduction into GoCD using docker. We are going to setup a GoCD environment consisting of a server, an agent and deployable material. Further we are going to configure a deployment pipeline and build an node.js application.

As promised here’s the sequel to my last tutorial: Part 1

This time we create a basic rich application with JavaFX. It will be quite simple, but still a good example to show how you can structure a complex project according to MVC.

Let’s write a Laravel application - Sortable table

Wed, 04 Feb 2015 14:33:28 +0000

I want to show how you can create a sortable table and reuse the code with any model you want to display. As we don’t want to write any function or definition twice or more, let’s extend the BaseController class with the function to get sorted items from a variable model.
