Django Formset errore di convalida gestione-forma

Question

Ho una forma e un formset sul mio modello. Il problema è che il formset lancia un errore di validazione sostenendo che il modulo di gestione è "mancante o è stato manomesso".

Qui è la mia vista

@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))

Answer 1

Per evitare questo errore solo avvolgere la formset POST di delimitazione in un blocco try/except in questo modo.

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') 

La richiesta POST dal blogform manca l'input nascosto 'ManagementForm' che è necessario per il vostro delblogformset e, quindi, viene generata l'errore di convalida. Noi avvolgiamo in un blocco try/except, perché sappiamo che se ValidationError è stata sollevata rispetto al post è stato pensato per il vostro blogform e non delblogformset.

Per ulteriori informazioni vedi Documentazione Django: http://docs.djangoproject.com/en/dev/topics/forms/formsets/#understanding-the-managementform

Answer 2

ho capito questo dopo l'esecuzione nello stesso errore. Nelle situazioni in cui si utilizza un modulo e un formset nella stessa vista e modello, il modulo deve essere elaborato prima del formset per evitare di generare un errore di convalida del formset.

di importanza Inoltre, if request.method == 'POST': deve essere usato solo sul formset. Così il precedente viene visualizzato come di seguito nella visualizzazione:

@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))
