I am writing the create function in postViewset, specifically I want to create an article, I can upload both photos or videos, but when testing the postman, the result is still created, however, then it Media is empty, I try print (media_image_request) and print(media_video_request) the result is []. Please help me fix this error in the function create and the partial_update.
