Odoo Actions And Buttons

Odoo Actions and Buttons

Goal

Add interactivity to the UI using buttons that trigger Python code or other actions.

1. Adding Buttons to Views

Buttons are usually placed in the <header> of a form view or inside the <sheet>/<list>.

Example (Header Button):

<form>
    <header>
        <button name="action_sold" type="object" string="Sold" class="oe_highlight"/>
        <button name="action_cancel" type="object" string="Cancel"/>
    </header>
    <sheet>
        <!-- Fields -->
    </sheet>
</form>

• string: Label of the button.
• class="oe_highlight": Highlights the button (primary color).

2. Button Types

Type "object"

Triggers a Python method on the model.

• XML: type="object", name="method_name"
• Python: Define a public method (no underscore prefix).

Example:

def action_sold(self):
    for record in self:
        if record.state == 'canceled':
            raise UserError("Canceled properties cannot be sold.")
        record.state = 'sold'
    return True

• Exceptions: Use odoo.exceptions.UserError to stop execution and warn the user.
• Return: Always return True (or an action dictionary) for public methods.

Type "action"

Triggers a specific Window Action (e.g., open a wizard, report, or another view).

• XML: type="action", name="%(module_name.action_xml_id)d"

Example:

<button type="action" name="%(estate.action_estate_offer)d" string="Offers"/>

3. Object Buttons inside Lists

You can add buttons to list views (or inside form sheets).

• Icon Buttons: Use icon="fa-check" (FontAwesome) instead of string for compact buttons.

Example:

<list>
    <field name="name"/>
    <button name="action_confirm" type="object" icon="fa-check" title="Confirm"/>
    <button name="action_cancel" type="object" icon="fa-times" title="Cancel"/>
</list>
