Trouble accessing message_dict of ValidationError

[Rosemary McCloskey]

Hi,

I'm writing a view to create a model, and am trying to capture any ValidationErrors and display them to the user. I have code that looks like this:

  # exceptions is a dict of errors already encountered

  try:

    # create model

  except ValidationError as e:

    for key, msg in e.message_dict.items():                                                            

      exceptions.update({key: str(msg[0])}) 

I'm getting the following error:

  Traceback (most recent call last):

    File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py", line 114, in get_response

      response = wrapped_callback(request, *callback_args, **callback_kwargs)

    File "/home/rmcclosk/Documents/Shipyard/shipyard/method/views.py", line 529, in method_revise

      for key, msg in e.message_dict.items():

    File "/usr/local/lib/python2.7/dist-packages/django/core/exceptions.py", line 96, in message_dict

      for field, messages in self.error_dict.items():

  AttributeError: 'ValidationError' object has no attribute 'error_dict'

This looks like a Django bug to me, but I googled around and couldn't find anything similar. The same error also happens if I just try to print(e.message_dict) instead of iterating through it, it seems like just accessing message_dict is causing the problem. Any ideas about what could be wrong?

Thanks!
