Django：保存表單時語法錯誤'意外的EOF'

Question

我有一個設置頁面，它有兩種形式來處理兩種不同模型的設置。簡介模型表單起作用。廚師模型表單沒有。表單失敗，並沒有拋出一個Django錯誤頁面 - 所以在使用pdb時，我發現表單無效，並且拋出了一個語法錯誤。

我很困惑這個錯誤來自哪個字段。任何幫助將不勝感激。謝謝！

錯誤：

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

廚師表

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"),

    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!'} 

查看：

@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)) 

要更多信息添加到這個錯誤，我能拉起來這個破碎的管道錯誤：

Answer 1

的SyntaxError :: SyntaxError錯誤是來自於Python語法分析器本身。我認爲這與你的表單數據沒有任何關係。

我想在這段代碼上運行pylint，pyflakes或pep8 compliance，看看它說了什麼。

我懷疑解析你的一個Python文件，可能是上面顯示的文件之一的一部分，但不完全是你在那裏。例如，一個流浪（或[或{字符某處可能會導致此類問題，因爲表單代碼不會執行直到調用。

ChefForm聲明支持的「required = True」部分上的奇數縮進這個猜測，你的編輯器因爲某些問題而錯誤地縮進了，可能高於整個「class ChefForm」的聲明，我們在這裏看不到這個

編輯：對不起，我錯了我的最後答覆。我正在想別的東西。

更換％s與％d在這條線：

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