Ошибка проверки формы управления Django Formset

Question

У меня есть форма и набор форм на моем шаблоне. Проблема заключается в том, что набор форм выдает ошибку проверки, утверждая, что форма управления «отсутствует или подделана».

Вот мой взгляд

@login_required
def home(request):

    user = UserProfile.objects.get(pk=request.session['_auth_user_id'])
    blogz = list(blog.objects.filter(deleted='0'))
    delblog = modelformset_factory(blog, exclude=('poster','date' ,'title','content')) 
    if request.user.is_staff== True:
        staff = 1
    else:
        staff = 0
    staffis = 1

    if request.method == 'POST':
        delblogformset = delblog(request.POST)
        if delblogformset.is_valid():
        delblogformset.save()
            return HttpResponseRedirect('/home')

    else:
        delblogformset = delblog(queryset=blog.objects.filter( deleted='0'))


        blogform = BlogForm(request.POST)
        if blogform.is_valid():
            blogform.save()
        return HttpResponseRedirect('/home')

    else:
        blogform = BlogForm(initial = {'poster':user.id})
    blogs= zip(blogz,delblogformset.forms)  

    paginator = Paginator(blogs, 10) # Show 25 contacts per page

    # Make sure page request is an int. If not, deliver first page.
    try:
        page = int(request.GET.get('page', '1'))
    except ValueError:
        page = 1

    # If page request (9999) is out of range, deliver last page of results.
    try:
        blogs = paginator.page(page)
    except (EmptyPage, InvalidPage):
        blogs = paginator.page(paginator.num_pages)

    return render_to_response('home.html', {'user':user, 'blogform':blogform, 'staff': staff, 'staffis': staffis, 'blog':blogs, 'delblog':delblogformset}, context_instance = RequestContext( request ))

мой шаблон

{%block content%}


<h2>Home</h2>

 {% ifequal staff staffis %}
 {% if form.errors %}
  <ul>
        {% for field in form %}
          <H3 class="title">

          </H3>
        {% endfor %}
    </ul>
  {% endif %}


   <h3>Post a Blog to the Front Page</h3>
 <form method="post" id="form2" action=""  class="infotabs accfrm">
    {{ blogform.as_p }}
   <input type="submit" value="Submit" />
 </form> 
 <br>
 <br>
{% endifequal %}


 <div class="pagination">
    <span class="step-links">
        {% if blog.has_previous %}
            <a href="?page={{ blog.previous_page_number }}">previous</a>
        {% endif %}

        <span class="current">
            Page {{ blog.number }} of {{ blog.paginator.num_pages }}.
        </span>

        {% if blog.has_next %}
            <a href="?page={{ blog.next_page_number }}">next</a>
        {% endif %}
    </span>


<form method="post"  action=""  class="usertabs accfrm">
{{delblog.management_form}}
{% for b, form in blog.object_list %}
<div class="blog">

<p>{{b.content}}</p>

 {% ifequal staff staffis %}<p>{{form.as_p}}<input type="submit" value="Delete" /></p>{% endifequal %}
</div>
{% endfor %}
 </form>




{%endblock%}

Answer 1

Чтобы избежать этой ошибки, просто оберните POST-ограничение формы набора в блок try / Кроме того, как это.

from django.core.exceptions import ValidationError # add this to your imports

if request.method == 'POST':
   try:
      delblogformset = delblog(request.POST)
   except ValidationError:
      delblogformset = None
   if delblogformset and delblogformset.is_valid():
      delblogformset.save()
          return HttpResponseRedirect('/home')

В запросе POST от вашего blogform отсутствует скрытый ввод 'ManagementForm', необходимый для вашего delblogformset, и, следовательно, выдается ошибка проверки. Мы заключаем в блок try / Кроме того, потому что мы знаем, что если ValidationError был поднят, то POST был предназначен для вашего blogform, а не delblogformset.

Для получения дополнительной информации см. Django docs: http://docs.djangoproject.com/en/dev/topics/forms/formsets/#understanding-the-managementform

Answer 2

Я понял это после столкновения с той же ошибкой. В ситуациях, когда вы используете форму и набор форм в одном представлении и шаблоне, форму следует обрабатывать перед набором форм, чтобы избежать возникновения ошибки проверки набора форм.

важности. Также, if request.method == 'POST': ДОЛЖЕН использоваться ТОЛЬКО в форме. Таким образом, выше будет выглядеть как показано ниже:

@login_required
def home(request):

    user = UserProfile.objects.get(pk=request.session['_auth_user_id'])
    blogz = list(blog.objects.filter(deleted='0'))
    delblog = modelformset_factory(blog, exclude=('poster','date' ,'title','content')) 
    if request.user.is_staff== True:
        staff = 1
    else:
        staff = 0
    staffis = 1

    blogform = BlogForm(request.POST)
    if blogform.is_valid():
        blogform.save()
        return HttpResponseRedirect('/home')

   else:
    blogform = BlogForm(initial = {'poster':user.id})

    if request.method == 'POST':
    delblogformset = delblog(request.POST)
    if delblogformset.is_valid():
        delblogformset.save()
        return HttpResponseRedirect('/home')

    else:
        delblogformset = delblog(queryset=blog.objects.filter( deleted='0'))



    blogs= zip(blogz,delblogformset.forms)  

    paginator = Paginator(blogs, 10) # Show 25 contacts per page

    # Make sure page request is an int. If not, deliver first page.
    try:
        page = int(request.GET.get('page', '1'))
    except ValueError:
        page = 1

    # If page request (9999) is out of range, deliver last page of results.
    try:
        blogs = paginator.page(page)
    except (EmptyPage, InvalidPage):
        blogs = paginator.page(paginator.num_pages)

    return render_to_response('home.html', {'user':user, 'blogform':blogform, 'staff': staff, 'staffis': staffis, 'blog':blogs, 'delblog':delblogformset}, context_instance = RequestContext( request ))
