How to call django template in order to use it through Jquery?
Create a Django view which renders just the HTML for the form using your preferred template. Then use $.ajax() with dataType: "html" to get the code for the form for use in your overlay.
I've installed the django-newsletter application, and customized the subscribing form. But, right now, I'd like to print it through a Jquery Overlay, instead of a flatpage containing that form. 
Problem is I don't know how to include this flatpages elements into every page where the link calling the overlay will be present; and I don't know which approach would be the most performant.
Please light my way :)
Thank you!
