Image upload on record that already exists

Hi

I'm doing a test to insert images in mongodb with GridFS.

I am using mongoengine.

I have this code:

def index (request):

     if request.method == 'POST':

        MovieTitle = 'Avatar'

        Movie movie = (= movieTitle movieTitle)

       

        my_painting = Movie (movieTitle = movieTitle)

        my_painting.MovieCover request.FILES = ['file']

        my_painting.save ()

     return render_to_response ('index.html', {},

                               context_instance = RequestContext (request))

So far so good, he enters the Avatar movie, and upload the image properly to GridFS from mongo.

But if I now enter another photo as you want this same movie Avatar, and do so:

def index (request):

     if request.method == 'POST':

        Movie movie = (id = '518b5ec58774a7100c7803e1 ')

       

        my_painting = Movie (id = '518b5ec58774a7100c7803e1 ')

        my_painting.MovieCover request.FILES = ['file']

       

        my_painting.save ()

     return render_to_response ('index.html', {},

                               context_instance = RequestContext (request))

He inserts a new record with that id, and that id is related to the previous film already inserted.

Does anyone know what I'm doing wrong?
