AttributeError: This QueryDict instance is immutable django

  1. In Django, request.POST is a QueryDict instance used to access the HTTP POST parameters.
  2. If you receive an "AttributeError: This QueryDict instance is immutable" error, it means you are trying to modify the POST parameters, which is not allowed because QueryDict instances are immutable.
  3. To fix this, you should make a copy of the QueryDict and modify the copy instead of the original.
  4. You can do this by using the copy() method to create a mutable copy of the QueryDict.
  5. Then, you can make changes to the copy as needed without encountering the immutable attribute error.
