what is best way to pass form from non editable view to a editable window then save it and send values back to previously non editor view

[sushovan majumdar]

I have a django view which has simple form with key value pair. 

I have made the fields non editable. I'm providing a edit button which will open a new window dialog and there i will load the same form in editable view and provide option to save or add new rows to form.

When user clicks on save on second window i want it to close and initial parent view to be refreshed with new values of the form.

I have never done this so I would appreciate if someone helps me understand on how to achieve this.
