How to Create and Manage a Gantt Chart View in Odoo 15 in Steps

Create and Manage a Gantt Chart View in Odoo 15 requires a combination of models and views. Let’s go through the steps in detail.

Step 1: Define the Model for the Gantt View

First, you need to define a model that will represent the data that you want to display in the Gantt chart. Below is a simple example of a model representing tasks or project tips that can be displayed in a Gantt chart.

In this model:

• name: The name of the task or project.
• date_start: The start date of the task.
• date_deadline: The deadline or end date of the task.
• partner_id: The associated partner (client or vendor).
• tag_ids: Tags related to the task (e.g., priority, category).

You can extend this model based on your business needs by adding additional fields such as resource allocation, progress percentage, or dependencies.

Step 2: Define the Gantt View in XML

Once the model is defined, you will need to create an XML file to define how this model should be presented in a Gantt view. You will use the <gantt> tag in the XML to display the data in a Gantt chart format. Here’s an example of the XML configuration for the Gantt view:

In this XML definition:

• date_start: The field representing the task start date.
• date_stop: The field representing the task end date (deadline).
• default_group_by: This is used to group the tasks by a specific field (in this case, partner_id).

This view will display tasks in a Gantt chart format with bars representing the task durations, grouped by the assigned partner.

Step 3: Add Gantt View to the Action

To make the Gantt view accessible within Odoo, you need to modify the action to include the Gantt view. This is done by adding the gantt view mode to the view_mode attribute in the corresponding action. Here’s an example:

In this action definition:

• view_mode: Specifies the views available for this model (e.g., tree, form, calendar, graph, kanban, and gantt).
• view_id: This links to the tree view for this model, which serves as the default view.

By including gantt in the view_mode, users can now switch to the Gantt chart view directly from the interface.

Step 4: Testing the Gantt Chart View

After setting up the model and the XML views, you need to test the functionality. Once the code is implemented, you can access the view by navigating to the relevant menu and selecting the Gantt chart option. Here’s an example of how the Gantt chart view might appear:

• Tasks are displayed as horizontal bars.
• The length of each bar represents the duration of the task.
• Bars are grouped by the partner or any other field specified in default_group_by.
• You can filter tasks by day, week, or year.
• Different colors may represent different resources or statuses, depending on the configuration.

Advanced Features in the Gantt View

Once you are comfortable with the basic Gantt chart functionality, you can explore more advanced features to enhance your chart:

• Resource Allocation: Add resource fields to show how tasks are allocated to specific resources.
• Progress Bars: Show task completion percentage directly on the Gantt chart to track progress visually.
• Dependencies: You can define dependencies between tasks (e.g., one task must finish before another can start).
• Coloring Tasks: Use colors to indicate the status of tasks, priorities, or types of tasks.
• Custom Scales: Modify the scale to display data in different time units (e.g., days, weeks, months).
