Django. Edit model form in popup in admin
If you want to open a popup, simply create a link to your 'add' view with the following attribute on that link onclick='return showAddAnotherPopup(this);'
Is there any ready apps for django admin, that allows to edit model in popup? 
I want next functionallity:

View edit form for model in popup.
On model save - update row in list of models. 

Motivation: reduce page reloads. 
Also, if there any solutions oriented on massive manual data updates for django? I've taken a look at django grappelli - it improves view of data, but edit data is still not usable. 
P.S.: If such kind of app is not available - I'll start open source project.
