Hi, i had question in django rest framework

Hello I am a backend developer who is developing python django.
I sent you an e-mail because I had a question.
Currently, my company provides web services using pure django.
As the company grew bigger and bigger,
the direction of development was decided through api communication by separating the front and backend from one django project,
and we are trying to proceed with api communication using the django rest framework.
At this time, do I have to pay the usage fee when I want to develop it using the django rest framework for commercial purposes in the project currently being serviced by the company?
Or if you can use it without paying the usage fee, do you have to disclose the source or any restrictions under the license?

You are probably doing something wrong. Try to do things correctly
instead and see if that doesn't solve your problems.

Kind regards,

Error:

column "connection_type_id" of relation "connection_details_test" does not exist ( There is no column connection_type_id, why its looking for this column, should I change my model?)

in that case you don't need to put it as a field in form, it will be added automatically in the form.
