Question

我试图添加功能来编辑和删除帖子。我用Google搜索，似乎有两个选项，创建像这里的函数，How do I edit and delete data in Django?或只使用像这里的通用编辑视图：Create, Update and Delete in Django我个人想要使用通用编辑视图，但它＆＃39 ;有点难以理解，而不仅仅是创建函数。如果您可以帮助我使用通用编辑视图，我将不胜感激。

def post(request, slug):
    single_post = get_object_or_404(Post, slug=slug)
    single_post.views += 1  # increment the number of views
    single_post.save()      # and save it
    t = loader.get_template('main/post.html')
    context_dict = {
        'single_post': single_post,
    }
    c = Context(context_dict)
    return HttpResponse(t.render(c))
def add_post(request):
    context = RequestContext(request)
    if request.method == 'POST':
        form = PostForm(request.POST, request.FILES)
        if form.is_valid():  # is the form valid?
            form.save(commit=True)  # yes? save to database
            return redirect(index)
        else:
            print form.errors  # no? display errors to end user
    else:
        form = PostForm()
    return render_to_response('main/add_post.html', {'form': form}, context)




class Post(models.Model):
    category = models.ForeignKey(Category)
    created_at = models.DateTimeField(auto_now_add = True)
    title = models.CharField(max_length = 100)
    content = models.TextField()
    url = models.URLField(max_length=250, blank=True)
    ups = models.IntegerField(default=0)
    down = models.IntegerField(default=0)
    score = models.IntegerField(default=0)
    views = models.IntegerField(default=0)
    image = models.ImageField(upload_to="images",blank=True, null=True)
    slug = models.CharField(max_length=100, unique=True)


    def save(self, *args, **kwargs):
        self.slug = uuslug(self.title, instance=self, max_length=100)
        super(Post, self).save(*args, **kwargs)
    def __unicode__(self):
        return self.title       



class PostForm(forms.ModelForm):
    title = forms.CharField(max_length=128, help_text="plz enter")
    views = forms.IntegerField(widget=forms.HiddenInput(), initial=0)
    class Meta:
        model = Post
        fields = ['title', 'content', 'image', 'views', 'category']

以下是每个

的示例

在views.py

from django.contrib.auth.decorators import login_required
from django.utils.decorators import method_decorator
from django.views.generic.edit import CreateView, UpdateView, DeleteView
from django.http import HttpResponse, HttpResponseRedirect
from django.core.urlresolvers import reverse

from .models import *
from .forms import *

class PostCreateView(CreateView):
   model = Post
   form_class = PostForm
   template_name = 'form.html'

   def form_valid(self, form):
      self.object = form.save(commit=False)
      # any manual settings go here
      self.object.save()
      return HttpResponseRedirect(self.object.get_absolute_url())

   @method_decorator(login_required)
   def dispatch(self, request, *args, **kwargs):
      return super(PostCreateView, self).dispatch(request, *args, **kwargs)


class PostUpdateView(UpdateView):
   model = Post
   form_class = PostForm
   template_name = 'form.html'

   def form_valid(self, form):
      self.object = form.save(commit=False)
      # Any manual settings go here
      self.object.save()
      return HttpResponseRedirect(self.object.get_absolute_url())

   @method_decorator(login_required)
   def dispatch(self, request, *args, **kwargs):
     return super(PostUpdateView, self).dispatch(request, *args, **kwargs)


class PostDeleteView(DeleteView):
   model = Post

   def get_success_url(self):
      return reverse('post-index')  # Or whatever you need

   @method_decorator(login_required)
   def dispatch(self, request, *args, **kwargs):
      return super(PostDeleteView, self).dispatch(request, *args, **kwargs)

urls.py上的

，你需要像

这样的东西

from django.conf.urls import patterns, url
from .views import *

urlpatterns = patterns('',
   url(r'^add/$', PostCreateView.as_view(), name='post-add'),
   url(r'^(?P<pk>\d+)/edit/$', PostUpdateView.as_view(), name='post-edit'),
   url(r'^(?P<pk>\d+)/delete/$', PostDeleteView.as_view(), name='post-delete'),
)

您需要一个post_confirm_delete.html模板，例如：

<form action="" method="post">{% csrf_token %}
   <p>Are you sure you want to delete "{{ object }}"?</p>
   <input type="submit" value="Confirm" />
</form>

希望这就是你要找的东西。
