how to hook into render_field from request

[vanderzielj]

I just ran across your package today - very convenient! I had previously viewed a StackOverflow post from someone who had created a Django filter to add a Bootstrap class to erroneous input items but figured correctly that someone in the world must have had the same problem and addressed it with tested code.

I am intrigued by the idea of a context process but having only implemented one so far (for breadcrumbs) it is not obvious to me how you would determine that a render_field request was being processed based on the request item. Could someone provide a hint for me?

Thanks,

Justin
