How to introspect django model fields?

Question

I am trying to obtain class information on a field inside a model, when I only know name of the field and name of the model (both plain strings). How is it possible?

Answer 1

The answer from Anurag Uniyal to use get_field_by_name is now (5 years later) outdated as get_field_by_name is deprecated. Django will give you the following hint:

RemovedInDjango110Warning: 'get_field_by_name is an unofficial API that has been deprecated. You may be able to replace it with 'get_field()'

API docs for get_field are here.
