功能與通用檢視的最小示例

用於建立物件的功能檢視的示例。排除註釋和空行，我們需要 15 行程式碼：

# imports
from django.shortcuts import render_to_response
from django.http import HttpResponseRedirect

from .models import SampleObject
from .forms import SampleObjectForm

# view functioon
def create_object(request):
    
    # when request method is 'GET', show the template
    if request.method == GET:
        # perform actions, such as loading a model form
        form = SampleObjectForm()
        return render_to_response('template.html', locals())
    
    # if request method is 'POST', create the object and redirect
    if request.method == POST:
        form = SampleObjectForm(request.POST)

        # save object and redirect to success page if form is valid
        if form.is_valid:
            form.save()
            return HttpResponseRedirect('url_to_redirect_to')

        # load template with form and show errors
        else:
            return render_to_response('template.html', locals())

用於執行相同任務的基於類的通用檢視的示例。我們只需要 7 行程式碼即可完成相同的任務：

from django.views.generic import CreateView

from .models import SampleObject
from .forms import SampleObjectForm

class CreateObject(CreateView):
    model = SampleObject
    form_class = SampleObjectForm
    success_url = 'url_to_redirect_to'
