Django

Question

提交后，我收到错误 400 和以下消息：

create_foo.html:

<form class="modal-form" method="post" action="{% url 'create_foo'> %}">
    {% csrf_token %}    
    {{ forms }} 
</form>

create_foo.py:

@require_POST
@login_required(login_url='/login/')
def create_foo(request):
#
#
if form.is_valid():
        return HttpResponse('Success', status=201)
return JsonResponse({'html': render_to_string('create_foo.html', {'forms': form}), 'message': 'Failed'}, status=400)

我遇到错误 400 时遇到问题我有一个带有消息错误的表单。

我无法改进表格上的数据并继续，并且出现错误：

/usr/local/lib/python2.7/dist-packages/django/template/defaulttags.py:67: UserWarning: A {% csrf_token %} was used in a template, but the context did not provide the value.  This is usually caused by not
       using RequestContext.
         "A {% csrf_token %} was used in a template, but the context "

警告是因为您在调用 render_to_string 时没有包含 request。将其更改为：

render_to_string('create_foo.html', {'forms': form}, request=request)

Django - 在模板中使用了 {% csrf_token %}

Django - {% csrf_token %} was used in a template
