How to Show a Confirmation Message on Button Click in Odoo

Adding a confirmation message on button click in Odoo is a great way to ensure users confirm their actions before proceeding with critical tasks. This feature helps prevent unintended actions such as deleting records or finalizing orders. In this guide, we'll show you how to easily add a confirmation message to buttons in Odoo form views, giving users a chance to review their actions before executing them.

Why Use a Confirmation Message in Odoo?

Using a confirmation message in Odoo offers several benefits:

  • ▹ Prevent Mistakes: Confirmation messages help prevent accidental actions such as deleting records or triggering irreversible processes.
  • ▹ Enhanced User Experience: Giving users the opportunity to confirm their choices improves the overall user experience and avoids confusion.
  • ▹ Increased Control: Developers and admins can ensure that important actions are intentional by prompting users with a confirmation message.

Step-by-Step Guide to Adding a Confirmation Message to a Button in Odoo

Follow these steps to add a confirmation message to a button in Odoo.

Step 1: Define the Button in the XML Form View

First, you need to define the button in the form view’s XML file. You can add the confirmation message by using the confirm attribute within the button element. Here’s an example:

xml

<record id="view_task_form" model="ir.ui.view">
    <field name="name">project.task.form</field>
    <field name="model">project.task</field>
    <field name="arch" type="xml">
        <form string="Task">
            <header>
                <button name="action_done" type="object" string="Mark as Done" class="btn-primary"
                        confirm="Are you sure you want to mark this task as done?"/>
            </header>
            <sheet>
                <group>
                    <field name="name"/>
                    <field name="description"/>
                </group>
            </sheet>
        </form>
    </field>
</record>

In this example, the confirm attribute is used to display a confirmation message. When the button is clicked, the message "Are you sure you want to mark this task as done?" will appear, prompting the user to confirm their action.

Step 2: Define the Python Method for the Button Action

After adding the button in the form view, you need to define the Python method that will be executed when the button is clicked. Here is an example of how to implement the method:

python

from odoo import models, fields

class Task(models.Model):
    _inherit = 'project.task'

    def action_done(self):
        self.write({'state': 'done'})

The action_done method changes the state of the task to "done" after the user confirms their action. This method can be customized to execute any business logic you need.

Step 3: Test the Confirmation Message

Once you've added the button and defined the Python method, it's important to test the confirmation message to ensure that it appears as expected and the action is correctly triggered after confirmation.

Customizing the Confirmation Message in Odoo

You can customize the confirmation message to suit different contexts in your Odoo application. For example, you can modify the text based on the action being performed or the specific record being affected. This flexibility helps you deliver a more personalized and user-friendly experience.

Advanced Use Cases for Confirmation Messages

There are several advanced use cases for confirmation messages in Odoo:

  • ▹ Deletion Confirmation: When users attempt to delete records, a confirmation message can help prevent accidental deletions.
  • ▹ Validation of Orders: For processes like order confirmation, a confirmation message ensures that users intend to finalize their actions.
  • ▹ Triggering Complex Workflows: Before triggering complex workflows, a confirmation message gives users a chance to review their actions.
