I am trying to call a view recursively. Below is my code.
views.py
def survey_start(request):
post = models.Post.objects.all().order_by('id')
return HttpResponseRedirect(reverse('post_form_upload',args=(post[0].id,)))
def post_form_upload(request, id):
post = get_object_or_404(models.Post, id=id)
if request.method == 'GET':
content = post.content
form = CommentModelForm(content = content)
else:
form = CommentModelForm(request.POST)
if form.is_valid():
message = form.cleaned_data['message']
created_at = form.cleaned_data['created_at']
post1 = models.Comment.objects.create(post = id,
message = message,
created_at = created_at)
return HttpResponseRedirect(reverse('post_form_upload',
args= (post.next_id,)))
return render(request, 'survey_forms/post_form_upload.html',{
'form':form,
})
urls.py
urlpatterns = [
url(r'^post/form_upload.html$',views.survey_start, name='survey_start'),
url(r'^post/(?P<id>\d+)/post_form_upload.html$',views.post_form_upload, name='post_form_upload'),
]
I have two questions.
1. I keep on getting this error. It does enter the view. I printed a counter to check.
Reverse for 'post_form_upload' with arguments '()' and keyword arguments '{}' not found. 1 pattern(s) tried: ['survey_forms/post/(?P<id>\\d+)/post_form_upload.html$']

- Each post is displayed in one single page. The user must navigate from one page to other on clicking "next". So I am calling this view post_upload_form recursively. Is this the right approach?
Thanks.
