Django: AttributeError - Object has no attribute


Question

This view is throwing the AttributeError saying :'PhotoForm' object has no attribute 'reservation'. What happens- the function passes, but doesn't actually upload the image. In debugging it, the form is not valid.

I tried printing

  • form.reservation
  • form.message
  • form.photo

But that shows this traceback ( which is the reason why the form isn't valid & not completing the function.

As I built this off other functions that are working, I'm a bit confused. Thanks for the help!

The HTML Form

<form action="/photo/new/" method="post">{% csrf_token %}
    <dl>
        <dt>{{ form.reservation.label }}</dt>
            <dd><select name="reservation"> {% for reservation in reservations %} <option value="{{reservation.id}}">{{reservation.date}} {{reservation.chef.cook.get_profile.firstname}} - {{reservation.guest.get_profile.firstname}}</option>{% endfor %}</select></dd>
        <dt>{{ form.photo.label }}</dt>
            <dd>{{ form.photo }}</dd>
        <dt> {{ form.message.label }}</dt>
            <dd>{{ form.message }}</dd>
    </dl>
<button type="submit">Submit</button>
</form>

The View

@login_required
def new_photo(request, template_name="photo/newphoto.html"):

  meals = Reservation.objects.filter(guest=request.user.id)
  form = PhotoForm(request.POST)
  form.data = { "reservations": meals }
  if request.method == 'POST':
    form.photographer = request.user
    form.data.get('reservation')
    print form.reservation
    print form.message
    print form.photo
    if form.is_valid():
      print" hellos"
      save_reservation_photo(request.FILES["photo"])
      photo = form.save(commit=False)
      photo.photographer = request.user
      photo.save()
      return HttpResponseRedirect('/photo/%d/' % photo.id )
  else:
    form = PhotoForm()

  data = {'form':form,'reservations':meals,
    'add':True
  }

  return render_to_response(template_name,
                            data,
                            context_instance=RequestContext(request))

The Form:

class PhotoForm(forms.ModelForm):
  class Meta:
    model = Photo
    fields = ('reservation','photo','message')

  def __init__(self, *args, **kwargs):
      super(PhotoForm, self).__init__(*args, **kwargs)

The Model:

class Photo(models.Model):

  photographer = models.ForeignKey(User)
  pub_date = models.DateTimeField(default=datetime.now,auto_now_add=True,db_index=True)
  reservation = models.ForeignKey(Reservation)

  message = models.CharField(default='',max_length=140)

  photo = models.ImageField(default='',upload_to="reservation_images/")

The traceback

Accepted Answer

The key was having files=request.FILES in the form.

@login_required
def new_photo(request, template_name="photo/newphoto.html"):

  form = PhotoForm( user= request.user, data=request.POST, files=request.FILES)

  if request.method == 'POST':
    form.photographer = request.user
    if form.is_valid():
      photo = form.save(commit=False)
      photo.photographer = request.user
      photo.save()
      return HttpResponseRedirect('/photo/%d/' % photo.id )

should not forms (with image or file fields) be initialized with request.FILES?

form = PhotoForm(request.POST, request.FILES)
