Форма не проходит валидацию, пишет, что все поля пусты Django
В представлении у меня есть 3 формы:
forms.py
class PostForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
self.user = kwargs.pop('user', None)
super(PostForm, self).__init__(*args, **kwargs)
class Meta:
model = Post
fields = ['subtitle', 'latitude', 'longitude', 'tags', 'body']
widgets = {
'body': forms.Textarea(attrs={'class': 'log-body editable'}),
'tags': forms.TextInput(attrs={'id': 'tags-field', 'class': 'log-form-field'}),
'latitude': forms.TextInput(attrs={'id': 'latitude-field', 'class': 'log-form-field'}),
'longitude': forms.TextInput(attrs={'id': 'longitude-field', 'class': 'log-form-field'}),
'subtitle': forms.TextInput(attrs={'id': 'subtitle-field', 'class': 'log-form-field'}),
}
labels = {
'subtitle': 'Subtitle:',
'tags': 'Tags:',
'latitude': 'Latitude',
'longitude': 'Longitude',
'body': ''
}
class ImageForm(forms.ModelForm):
images = forms.ImageField(label='Images', widget=forms.ClearableFileInput(
attrs={
'multiple': True,
'class': 'file-upload',
'id': 'file-upload-button-image',
'name': 'images'}
)
)
class Meta:
model = PostImage
fields = ('images',)
class VideoForm(forms.ModelForm):
videos = forms.FileField(label='Videos', widget=forms.ClearableFileInput(
attrs={
'multiple': True,
'class': 'file-upload',
'id': 'file-upload-button-video',
'name': 'images'
}
)
)
class Meta:
model = PostVideo
fields = ('videos',)
У меня есть шаблон, который создает пост и сохраняет видео и изображения, и это отлично работает. У меня возникают трудности с обновлением 'Post'.
class PostEditView(TemplateView):
template_name = 'Logging/edit view.html'
post_form_class = PostForm
image_form_class = ImageForm
video_form_class = VideoForm
def get_context_data(self, **kwargs):
context = super(PostEditView, self).get_context_data(**kwargs)
context['post_pk'] = self.kwargs['pk']
context['post_form'] = PostForm(instance=Post.objects.get(pk=self.kwargs['pk']))
context['image_form'] = ImageForm(empty_permitted=True, use_required_attribute=False)
context['video_form'] = VideoForm(empty_permitted=True, use_required_attribute=False)
context['images'] = PostImage.objects.filter(post_id=self.kwargs['pk'])
context['videos'] = PostVideo.objects.filter(post_id=self.kwargs['pk'])
return context
def post(self, request, *args, **kwargs):
context = self.get_context_data()
post_data = request.POST or None
if post_data.get('Delete'):
if len(post_data.getlist('img-index[]')) > 0:
for i in post_data.getlist('img-index[]'):
PostImage.objects.filter(id=i).delete()
if len(post_data.getlist('vid-index[]')) > 0:
for i in post_data.getlist('vid-index[]'):
PostVideo.objects.filter(id=i).delete()
print(post_data)
post_form = PostForm(data=post_data, instance=Post.objects.get(pk=self.kwargs['pk']), prefix='post')
print(post_form.is_bound)
post_form.is_valid()
print(post_form.errors)
images = request.FILES.getlist('image-images')
videos = request.FILES.getlist('video-videos')
if post_form.is_valid():
print('valid form')
for i in images:
instance = PostImage(image=i, post=context['post_pk'])
instance.save()
for v in videos:
instance = PostVideo(video=v, post=context['post_pk'])
instance.save()
return super(PostEditView, self).render_to_response(context)
def form_save(self, form, request):
obj = form.save(commit=False)
obj.user = request.user
obj.author = request.user.first_name + ' ' + request.user.last_name
obj.event_type = 'Log Entry'
obj.save()
messages.success(self.request, "{} posted successfully".format(obj))
return obj
Когда я вызываю is_valid() на post_form, он всегда говорит false, хотя и говорит, что он связан. Мой объект post действительно содержит данные из формы в моем шаблоне, включая токен csrf, но по какой-то причине форма никогда не является действительной и говорит, что все поля пусты.
от print(post_data):
<QueryDict: {'csrfmiddlewaretoken': ['h5uxuACKsvBcO4lrPB7yKbYgr0BsASEklT3GTp6R3t8na13TadAfjbihl2VyGvdC'], 'subtitle': ['Test with photos'], 'latitude': ['48.000'], 'longitude': ['112.000'], 'tags': ['[]'], 'images': [''], 'videos': [''], 'body': ['<p>body test 2 saa</p>']}>
из print(post_form.is_bound):
True
от print(post_form.errors):
<ul class="errorlist">

Я не могу разобраться в этом. Любая помощь была бы признательна!
