Hello,
Is there an easy way to implement a warning whereby the user is asked 'Are you sure you want to cancel this quotation?' before actually cancelling it?
It is very easy to hit cancel when actually just wanting to go back to list view from form view! As far as I can tell there is no easy way to undo that action.
Thanks, Lawrence
For buttons there exists the attribute confirm. When this attribute is set, then when the button is pressed a dialog box appears before the action is processed.
In the case of the Sales Quotation you can change the following line of the form view to implement a dialog box:
<button name="cancel" states="draft,sent" string="Cancel" groups="base.group_user"/>
to
<button name="cancel" states="draft,sent" string="Cancel" confirm="Are you sure you want to cancel this quotation?" groups="base.group_user"/>
Hi Andreas, thank you for this excellent answer. I am hoping to put this modification into a patch (so that I do not need to make the change each time I update the code). If you are able to help, please see http://help.openerp.com/question/27344/is-there-a-beginners-guide-to-writing-a-patch/. Thanks!
I have read into this some more and the way to ensure that changes remain even after updating is to create a new view which inherits the existing view.
