I'm using ModelForms with the generic editing views (create, update, delete). One of my aims in this exercise is to get to know some frameworks (Django + Bootstrap + a plugin (e.g. PDF.js)) and use as little custom code as possible.
I can create a 'document' record through the Admin site and the upload is saved in the 'files' location I set. When I try through my site, no file is uploaded, although the other fields will be updated (evidently the form validates). (The FileField IS nullable, because I want to be able to have a pointer to a non-digital asset). The relevant code:
# models.py
class document(models.Model):
ref_file = models.FileField(upload_to='documents/', blank=True, null=True)
def get_absolute_url(self):
return reverse('knowledge_manager:doc_detail', kwargs={'pk': self.pk})
# urls.py
urlpatterns = [
url(r'^doc$', views.docIndex.as_view(), name='doc_index'),
url(r'^doc/(?P<pk>\w+)/det', views.docUpdate.as_view(), name='doc_detail'),
url(r'^doc/new/$', views.docCreate.as_view(), name='doc_create'),
url(r'^doc/(?P<pk>\w+)/update', views.docUpdate.as_view(), name='doc_update'),
url(r'^doc/(?P<pk>\w+)/del', views.docDelete.as_view(), name='doc_delete')
]
# views.py
class docIndex(generic.ListView):
model = document
template_name = 'knowledge_manager/_index.html'
context_object_name = 'document_set'
class doc_detail(generic.DetailView):
model = reference
template_name = 'knowledge_manager/doc_detail.html'
context_object_name = 'document'
form_class = doc_form
success_url = reverse_lazy('knowledge_manager:doc_index')
class docCreate(generic.CreateView):
model = document
template_name = 'knowledge_manager/doc_detail.html'
form_class = doc_form
success_url = reverse_lazy('knowledge_manager:doc_index')
class docUpdate(generic.UpdateView):
model = document
template_name = 'knowledge_manager/doc_detail.html'
context_object_name = 'document'
form_class = doc_form
success_url = reverse_lazy('knowledge_manager:doc_index')
class docDelete(generic.DeleteView):
model = document
success_url = reverse_lazy('knowledge_manager:doc_index')
# forms.py
class doc_form(ModelForm):
class Meta:
model = document
fields = '__all__'
Questions:
- what do you think is going wrong? Surely ModelForms with FileFields initialise using 'request.FILES' as well as 'instance' and 'request.POST'?
- what's a good way to get debugging messages about what is actually getting posted? Using function views I used to just pop 'print('made it to here, value X is', value_x) - is there a better way than just overloading the standard functions of ModelForms etc?
