Django: SyntaxError 'unexpected EOF' while saving a Form

Question

I have a settings page which has two forms for handling the settings for two different Models. The Profile model form works. The Chef model form doesn't. The form fails gracefully, and isn't throwing a Django error page - so in using pdb, I found the form is not valid, and is throwing a Syntax Error.

I'm confused as to which field this error is coming form. Any help would be greatly appreciated. Thanks!

Error:

*** SyntaxError: SyntaxError('unexpected EOF while parsing', ('<string>', 0, 0, ''))

HTML

  {% if form.is_multipart %}
  <form enctype="multipart/form-data" method="post" action=".">{% csrf_token %}

Chef Form

class ChefForm(forms.ModelForm):
  class Meta:
    model = Chef
    fields = ('category','meal','price','language','address','neighborhood','city','state', 'country', 'menu')

  category = forms.ChoiceField(
        label=_("Food style"),
        choices=([('Afghan','Afghan'),('African','African'),('American','American'),]),
                                  required=True)

  meal = forms.ModelMultipleChoiceField(
        label=_("What is your best meal?"),
        queryset=Meal.objects.all(),

                                  required=True)

  price = forms.IntegerField(
        label=_("Price per person"),
        widget=forms.TextInput(),

  def __init__(self, *args, **kwargs):
      super(ChefForm, self).__init__(*args, **kwargs)
      self.fields['price'].widget.attrs = {
        'placeholder':'10'}
      self.fields['menu'].widget.attrs = {
        'placeholder':'Tacos!'}

View:

@login_required
def edit_chef(request, chef_id, template_name="chef/newchef.html"):

  chef = get_object_or_404(Chef, id=chef_id)
  if request.user != chef.cook:
    return HttpResponseForbidden()
  if request.method == 'POST':
    import pdb; pdb.set_trace()
    chefform = ChefForm(request.POST, instance=chef)
    if chefform.is_valid():
      chefform.save()
      return HttpResponseRedirect('/users/%d/' % request.user.id)
  else:
      return HttpResponseRedirect('/users/%d/' % request.user.id)
  data = { "chef":chef,
    "chefform":chefform } 
  return render_to_response(template_name,
                            data,
                            context_instance=RequestContext(request))

Answer 1

SyntaxError::SyntaxError comes from the Python parser itself. I don't think this has anything to do with your form data.

I'd try running pylint, pyflakes or pep8 compliance on this code and see what it says.

I'm suspecting an error parsing one of your Python files, possibly some part of one of the files that's shown above, but not exactly what you have there. For example, a stray ( or [ or { character somewhere might cause this kind of problem, since the Form code isn't executed until called.

The odd indentation on your "required=True" parts of the ChefForm declaration support this guess. Your editor is indenting incorrectly because of some issue, likely above the entire declaration of "class ChefForm" that we can't see here.

Answer 2

EDIT: sorry I'm mistaken with my last reply. I was thinking of something else.

replace the %s with %d on this line:

return HttpResponseRedirect('/users/%s' % request.user.id)
