Django pass object from view to next for processing

问题

If you have 2 views, the first uses modelform that takes inputted information from the user (date of birth, name, phonenumber, etc), and the second uses this information to create a table.

How would you pass the created object in the first view to the next view so you can use it in the second view's template

I'd appreciate any help you can share

回答1:

One approach is to put the object into a session in your first view, which you could then retrieve from the request.session in the second view.

def first_view(request):
    my_thing = {'foo' : 'bar'}
    request.session['my_thing'] = my_thing
    return render(request, 'some_template.html')

def second_view(request):
    my_thing = request.session.get('my_thing', None)
    return render(request, 'some_other_template.html', {'my_thing' : my_thing})

Use a HttpResponseRedirect to direct to the table view w/the newly created object's id. Here's an abbreviated example:

def first(request):
    if request.method == 'POST':
          form = MyModelForm(request.POST, request.FILES)
          if form.is_valid():
               my_model = form.save()

               return HttpResponseRedirect('/second/%s/' % (my_model.pk)) # should actually use reverse here.
      # normal get stuff here

def second(request, my_model_pk):
     my_model = MyModel.objects.get(pk=my_model_pk)

     # return your template w/my model in the context and render
