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 %}
  {% else %}
<h3>Profile Settings</h3>
  <form method="post" action=".">
  {% endif %}
    <dl>
      <dt>{{form.photo.label}}</dt>

      <dt>{{form.lastinitial.label}}</dt>
      <dd>{{form.lastinitial}}</dd>

    <button type="submit">Save</button>
</form>

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(),
                                  required=True)

  language = forms.ModelMultipleChoiceField(
        label=_("Languages spoken"),

  menu = forms.CharField(
        label=_("What's unique about your cooking & home? Pets? Have a family or roommates?"),
        widget=forms.TextInput(),
                                  required=True)  

  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))

To add more information to this bug, I was able to pull up this broken pipe error:

编辑：抱歉，我上次的回复弄错了。我在想别的东西。

在这一行用 %d 替换 %s：

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

SyntaxError::SyntaxError 来自 Python 解析器本身。我认为这与您的表单数据无关。

我会尝试在此代码上运行pylint、pyflakes或pep8 合规性，看看它说了什么。

我怀疑解析您的一个 Python 文件时出错，可能是上面显示的文件之一的一部分，但不完全是您那里的文件。例如，某个地方的杂散 ( 或 [ 或 { 字符可能会导致此类问题，因为表单代码在调用之前不会执行。

ChefForm 声明的“required=True”部分的奇怪缩进支持了这种猜测。由于某些问题，您的编辑器缩进不正确，可能高于我们在此处看不到的“class ChefForm”的整个声明。
