Hi,

Scenario:  
User input the values at form and click on the “Preview” button. We will use the value to generate the custom URL and calling third party website.

1. May I know how to open URL from Button?

I had tried to create the “ir.action.url” and using decorator “@ModelView.Button\_action(action)”. Tryton can open the URL from “ir.action.url” but it return fixed value of URL “ir.action.url”.

1. Beside question [1] or can dynamic value “URL” using button\_action?

Best regards

You could use a char field filled with the URL and display using the `url` widget.

But I think be good to allow dynamic action: [Allow ModelView.button\_action returns action values (#8766) · Issues · Tryton / Tryton · GitLab](https://bugs.tryton.org/issue8766)
