Django Crispy Forms Rendering Issue '辞書更新シーケンス要素＃0をシーケンスに変換できません'

Question

これを理解するために苦労しています。私は、このエラーコードが現れるいくつかの問題を見てきましたが、すべてがテンプレートのレンダリングのコンテキストに渡されないデータと関係しているようです。私は自分のデータがテンプレートに通っているのを知っています。クリスピーなフォームは私を捨てているシーンの背後に何かをしている必要がありますか？奇妙なことは、これは文字通り20分前に働いたことです。私はこれに影響を与えただろう、私が何を変えることができたのか分かりません。ここで

が私の見解です：

class ContactListView(View): 

    template = 'support_tracker/contact_list.html' 

    def get(self,request,*args,**kwargs): 
     staff_id = kwargs.pop('staff_id',False) 

     if staff_id: 
      staff = Staff.objects.get(pk=staff_id) 
     else: 
      staff = request.user.staff 
     contact_list = staff.contacts.all() 

     search_term = request.GET.get('search_term',False) 
     sort_by = request.GET.get('sort_by',False) 
     filter_by = request.GET.get('filter_by',False) 

     ##applying search term to determine contact_list 
      ... 
     ## 

     ##sorting of contact_list 
      .... 
     ## 

     ##filtering of contact_list 
      .... 
     ## 

     search_form = SearchForm() 
     sort_form = ContactListSortForm() 
     filter_form = FilterByStageForm() 

     ##pagination to determine contacts 
      ... 
     ## 

     context = { 
     'staff':staff, 
     'contacts':contacts, 
     'search_form':search_form, 
     'sort_form':sort_form, 
     'filter_form':filter_form, 
     'filter_by':filter_by, 
     'search_term':search_term, 
     'sort_by':sort_by, 
     } 

     print context 

     return render(request,self.template,context) 

マイフォーム：

##forms.py 
class SearchForm(forms.Form): 
    search_term = forms.CharField(max_length=30,label='') 

    def __init__(self,*args,**kwargs): 
     super(SearchForm,self).__init__(*args,**kwargs) 
     self.helper = FormHelper() 
     self.helper.form_class = 'form-inline' 
     self.helper.form_method = 'GET' 
     self.helper.field_template = 'bootstrap3/layout/inline_field.html' 
     self.helper.layout = Layout(
      InlineField('search_term',placeholder='Search'), 
      Submit('','Go',css_class='btn btn-primary'), 
      ) 

class FilterByStageForm(forms.Form): 
     filter_by = forms.ChoiceField(choices=get_stage_option_list(),required=False) 

    def __init__(self,*args,**kwargs): 
     super(FilterByStageForm,self).__init__(*args,**kwargs) 
     self.helper = FormHelper() 
     self.helper.form_class = 'form-inline' 
     self.helper.form_method = 'GET' 
     self.helper.field_template = 'bootstrap3/layout/inline_field.html' 
     self.helper.layout = Layout(
      InlineField('filter_by',placeholder='Filter By'), 
      Submit('','Filter',css_class='btn btn-primary'), 
      ) 

class ContactListSortForm(forms.Form): 
    sort_by = forms.ChoiceField(choices=(##options),required=False) 

    def __init__(self,*args,**kwargs): 
     super(ContactListSortForm,self).__init__(*args,**kwargs) 
     self.helper = FormHelper() 
     self.helper.form_class = 'form-inline' 
     self.helper.form_method = 'GET' 
     self.helper.field_template = 'bootstrap3/layout/inline_field.html' 
     self.helper.layout = Layout(
      InlineField('sort_by',placeholder='Sort By'), 
      Submit('','Sort',css_class='btn btn-primary'), 
      ) 

マイテンプレート：

{% extends 'co_tools/base.html' %} 
{% load crispy_forms_tags %} 

{% block content %} 
<div class='container'> 
    <div class='col-md-3 well'> 
     <h3><u>Search:</u></h3> 


     ## This is the part that trips it up. If I take the forms out, the rest of the page loads fine 
     {% crispy search_form %} 
     {% crispy sort_form %} 
     {% crispy filter_form %} 


     <a href='/support/new_contact/' class='btn btn-primary'>New Contact</a> 
    </div> 

    ...body... 

</div> 
{% endblock content %}

私はこれを引き起こしているのか分かりません。どんな助けでも大歓迎です。

Answer 1

問題を解決しました。私はこの特定のビットが問題を引き起こしていた理由を知りません。

私urls.pyで

、私は次の4つのURLの表現を追加しました... django.conf.urls輸入されたURLから

、第1は、もともと インポートビュー

urlpatterns = [ 
    ... 
    #meeting urls 
    url(r'^record_meeting/(?P<meeting_id>[0-9]+)/',views.EditMeetingView.as_view(),{'record':True}), 
    url(r'^record_meeting/$',views.EditMeetingView.as_view(),{'record':True}), 
    url(r'^edit_meeting/(?P<meeting_id>[0-9]+)/',views.EditMeetingView.as_view(),{'record':False}), 
    url(r'^add_meeting/$',views.EditMeetingView.as_view()), 
] 

が含まれます明らかに、試行錯誤に基づいて、この問題の原因となっていたurl(r'^add_meeting/$',views.EditMeetingView.as_view(),{'record':False})。追加の引数を削除した後、問題は解決しませんでした。なぜこれが最初の問題だったのか誰もが知っていますか？私はまだ理解していない。
