Django Crispy表单呈现问题'；无法将字典更新序列元素#0转换为序列'；

努力想弄明白这一点。我看到了一些问题，其中显示了此错误代码，但所有问题似乎都与未将数据传递到要呈现的模板上下文有关。我知道我的数据正在进入模板。酥脆的表单一定是在幕后做了什么，这让我很反感？奇怪的是，这在20分钟前就起作用了。我不知道我能改变什么，会影响这一切

以下是我的看法：

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)

我的表格：

##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'),
            )

我的模板：

{% 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 %}

{%extends'co_tools/base.html%}
{%load crispy_forms_tags%}
{%block content%}
搜索：
##这是绊倒它的部分。如果我把表格拿出来，页面的其余部分就可以加载了
{%crispy search_form%}
{%crispy sort_form%}
{%crispy filter_form%}
…身体。。。
{%endblock内容%}
