Django 如何使用基于类的视图处理表单(通过 get 或 post)

我正在try 学习基于类的视图，因为详细视图或列表视图并不是那么复杂.

我有一个搜索表单，我只是想看看我是否发送了一个查询来显示结果.

这是函数代码(不是我的，来自django的书):

def search_page(request):
    form = SearchForm()
    bookmarks = []
    show_results = False
    if 'query' in request.GET:
        show_results = True
        query = request.GET['query'].strip()
        if query:
            form = SearchForm({'query': query})
            bookmarks = Bookmark.objects.filter(title__icontains=query)[:10]


    show_tags = True
    show_user = True

    if request.is_ajax():
        return render_to_response("bookmarks/bookmark_list.html", locals(), context_instance=RequestContext(request))
    else:
        return render_to_response("search/search.html", locals(), context_instance=RequestContext(request))

忽略Ajax事实(现在只是为了使问题更容易)，我如何将其转换为基于类的视图呢？

我很快就试了试这样的东西:

class SearchPageView(FormView):
    template_name = 'search/search.html'

    def get(self, request, *args, **kwargs):
        form = SearchForm()
        self.bookmarks = []
        self.show_results = False
        if 'query' in self.request.GET:
            self.show_results = True
            query = self.request.GET['query'].strip()
            if query:
                form = SearchForm({'query': query})
                self.bookmarks = Bookmark.objects.filter(title__icontains=query)[:10]
        return super(SearchPageView, self).get(request, *args, **kwargs)

    def get_context_data(self, **kwargs):
        context = super(SearchPageView, self).get_context_data(**kwargs)
        context.update({
            'show_tags': True,
            'show_user': True,
            'show_results': self.show_results,
            'bookmarks': self.bookmarks
        })
        return context

不起作用，我得到一个:"‘NoneType’Object is not Callable"(‘NoneType’对象不可调用)

很公平，我今天就是从这些东西开始的.

那么，如何创建可以管理GET(如果需要还可以管理POST)请求的基于类的视图呢？

我还有一个例子:

@render_to('registration/register.html')
def register_page(request):
    if request.method == 'POST':
        form = RegistrationForm(request.POST)
        if form.is_valid():
            user = User.objects.create_user(
                username=form.cleaned_data['username'],
                password=form.cleaned_data['password1'],
                email=form.cleaned_data['email']
            )
            return HttpResponseRedirect('/accounts/register/success/')
    else:
        form = RegistrationForm()
    return locals()

这个会不会像第一个一样被" retrofit "呢？或者他们持不同的观点？

我很困惑.我不知道第一个是ProcessFormView，第二个是FormView还是什么.

谢谢

我以EDIT:个解决方案结束:

class SearchPageView(FormView):
    template_name = 'search/search.html'

    def get(self, request, *args, **kwargs):
        self.bookmarks = []
        self.show_results = False
        form = SearchForm(self.request.GET or None)
        if form.is_valid():
            self.show_results = True
            self.bookmarks = Bookmark.objects.filter(title__icontains=form.cleaned_data['query'])[:10]

        return self.render_to_response(self.get_context_data(form=form))


    def get_context_data(self, **kwargs):
        context = super(SearchPageView, self).get_context_data(**kwargs)
        context.update({
            'show_tags': True,
            'show_user': True,
            'show_results': self.show_results,
            'bookmarks': self.bookmarks
        })
        return context

我在这里把这个问题留给有同样问题的人:)
