'OneToOneField' Objekt hat kein Attribut 'Get' in funktionsbasierter Ansicht

Question

Ich schreibe ein zweiteiliges Formular, wo ich das Objekt im ersten Teil als OneToOneField für das Objekt im zweiten Teil übergeben wollen.

In views.py:

def object_entry(request): 
    if request.method == 'POST': 
     title_form = TitleEntry(request.POST) 
     object_form = ObjectEntry(request.POST) 
     if title_form.is_valid(): 
      title = title_form.cleaned_data['title'] 
      title_type = title_form.cleaned_data['title_type'] 
      title_lang = title_form.cleaned_data['lang'] 
      title_translation = title_form.cleaned_data['translation'] 
      title_currency = title_form.cleaned_data['currency'] 
      title_level = title_form.cleaned_data['level'] 
      title_note = title_form.cleaned_data['note'] 
      title_source = title_form.cleaned_data['source'] 
      new_title = title_form.save() 
      return new_title 

     else: 
      return render_to_response('objectinfo/objectregister_form.html', {'object_form': object_form, 'title_form': title_form}) 

     if object_form.is_valid(): 
      object_form.preferred_title = new_title 
      snapshot = object_form.cleaned_data['snapshot'] 
      work_type = object_form.cleaned_data['work_type'] 
      source = object_form.cleaned_data['source'] 
      brief_description = object_form.cleaned_data['brief_description'] 
      description_source = object_form.cleaned_data['description_source'] 
      comments = object_form.cleaned_data['comments'] 
      distinguishing_features = object_form.cleaned_data['distinguishing_features'] 
      new_object = object_form.save() 
      reorg.AccessionNumber.generate(new_object.pk) 

      return HttpResponseRedirect('/work/') 
      # return HttpResponseRedirect(reverse(description_edit, args=(new_object.pk,))) 

     else: 
      return render_to_response('objectinfo/objectregister_form.html', {'object_form': object_form, 'title_form': title_form}) 

    else: 
     title_form = TitleEntry() 
     object_form = ObjectEntry() 
     return render(request, 'objectinfo/objectregister_form.html', {'object_form': object_form, 'title_form': title_form}) 

Und in forms.py:

class ObjectEntry(ModelForm): 
    class Meta: 
     model = ObjectRegister 
     fields = ['snapshot', 'work_type', 'source', 'brief_description', 'description_source', 'comments', 'distinguishing_features', 'storage_unit', 'normal_unit'] 

class TitleEntry(ModelForm): 
    class Meta: 
     model = ObjectName 
     fields = ['title', 'title_type', 'lang', 'translation', 'currency', 'level', 'note', 'source'] 

Wenn Sie das Formular absenden er den Fehler 'ObjectName' object has no attribute 'get' zurückgibt. Traceback:

Was wäre der richtige Weg sein passieren new_title als OneToOneField von object_form.preferred_title?

Answer 1

Ihre Sicht gibt die neue Instanz zurück, wenn das Formular gültig ist. Das ist falsch, Sie sollten immer eine HTTP-Antwort zurückgeben.

Es ist eine gute Idee, nach der Verarbeitung eines gültigen Formulars umzuleiten, um doppelte Formulareinreichungen zu vermeiden.
