将视图与模板视图django合并

Question

I want that the landing page of my homepage is a form with an input and the user puts in stuff. So I followed a couple of tutorials and now I have this:

views.py:

def create2(request): 
  if request.method =='POST':
    form = LocationForm(request.POST)
    if form.is_valid():   
      form.save()
      return HttpResponseRedirect('')
  else:
    form = LocationForm()

  args = {}
  args.update(csrf(request))
  args['form'] = form
  return render_to_response('location/index.html', args)

and in my urls.py:

url(r'^$', 'core.views.create2'),

which works perfectly fine, if I go to 127.0.0.1:8000 I get to index.html and when put in something in the input it gets saved in the database. However, the old part of my homepage looks like this

class LandingView(TemplateView):
    model = Location
    template_name="location/index.html"
    def search
    ...

and the urls.py: url(r'^$', core.views.LandingView.as_view(), name='index') ,

which has a function search I So my question is, is there a way how I can merge the def create2 into my LandingView . I tried several things, but I am always ending up having the index.html without the input field. I also tried

def create2 
...
def search
...

but didn't work.

Does anyone know how to merge that together?

EDIT Thank you the working solution looks like this now

class Create(CreateView):
  model = coremodels.Location
  template_name = 'location/test.html'
  fields = ['title']
  def form_valid(self, form):
     form.save()
     return HttpResponseRedirect('')

    return super(Create, self).form_valid(form)

Depending on the results you are looking for, there are multiple ways to solve this:

1. Use CreateView and UpdateView

Django already provides some classes that render a form for your model, submit it using POST , and re-render the form with errors if form validation was not successful.

Check the generic editing views documentation.

2. Override get_context_data

In LandingView , override TemplateView 's get_context_data method, so that your context includes the form you are creating in create2 .

3. Use FormView

If you still want to use your own defined form instead of the model form that CreateView and UpdateView generate for you, you can use FormView , which is pretty much the same as TemplateView except it also handles your form submission/errors automatically.

In any case, you can keep your search function inside the class-based view and call it from get_context_data to include its results in the template's context.
