我如何在 Django 中创建适用于我所有视图的搜索

Question

我的 base.html 目前有一个搜索字段。这是一个片段

<nav class="navbar navbar-inverse navbar-fixed-top" role="navigation">
      <div class="container">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>
          <a class="navbar-brand" href="{% url 'posts:list'  %}">HEHTS</a>
        </div>
        <div id="navbar" class="collapse navbar-collapse">


          <form method="GET" action=" "  class="navbar-form navbar-right">
            <div class="input-group">{% csrf_token %}
              <input type="text" name="q" id="search" placeholder="search" value="{{ request.GET.q }}" class="form-control"
              style="width: 350px">


            <!--<input type="text" name="q" placeholder="search post" value="{{ request.GET.q }}"/>-->
            <!--<input type="submit" value="Search" />-->
        <!--</form>-->

              <ul id="search-results">

              </ul>

            <span class="input-group-btn">
            <button type="submit" class="btn btn-primary"><span style="font-size:1.4em" class="glyphicon glyphicon-search"></span> </button>
            </span>
            </div>
          </form>

          <ul class="nav navbar-nav">
            <li><a href="{% url 'posts:list'  %}">Home</a></li>
            <!--<li><a href="#">Sewp</a></li>-->
            {% if user.is_authenticated %}
            <li><a href="{% url 'admin:index' %}">Admin</a></li>
            <li><a href="{% url 'posts:create' %}">Create</a></li>
            {% endif %}

          </ul>
        </div><!--/.nav-collapse -->
      </div>
</nav>

这在我的 detail.html 视图中不起作用。它只在我的 post_list.html 视图中有效这里是他们两个的视图

  def post_detail(request, slug=None):
        instance = get_object_or_404(Post, slug=slug)
        if instance.publish > timezone.now().date() or instance.draft:
            if not request.user.is_staff or not request.user.is_superuser:
                raise Http404

        queryset_list = Post.objects.active()
        query = request.GET.get("q")
        if query:
            queryset_list = queryset_list.filter(
                    Q(title__icontains=query) |
                    Q(content__icontains=query) |
                    Q(user__first_name__icontains=query) |
                    Q(user__last_name__icontains=query)
            ).distinct()


        share_string = quote_plus(instance.content)
        template = "posts/post_detail.html"
        context = {
            "instance": instance,
            "name": instance.title,
            "share_string": share_string,
            "queryset_list": queryset_list
        }
        return render(request, template, context)


    def post_list(request):
        today = timezone.now().date()
        queryset_list = Post.objects.active()
        if request.user.is_staff or request.user.is_superuser:
            queryset_list = Post.objects.all()

        query = request.GET.get("q")
        if query:
            queryset_list = queryset_list.filter(
                    Q(title__icontains=query) |
                    Q(content__icontains=query) |
                    Q(user__first_name__icontains=query) |
                    Q(user__last_name__icontains=query)
            ).distinct()
        paginator = Paginator(queryset_list, 8)
        page_request_var = 'page'
        page = request.GET.get(page_request_var)
        try:
            queryset = paginator.page(page)
        except PageNotAnInteger:
            queryset = paginator.page(1)
        except EmptyPage:
            queryset = paginator.page(paginator.num_pages)
        template = "posts/post_list.html"
        name = "user"
        context = {
            "object_list": queryset,
            "name": name,
            "page_request_var": page_request_var,
            "today": today,
        }
        return render(request, template, context)

我想要的结果是让事情保持干燥，只需编写一次代码就可以在我的 base.html 中使用它，而且无论我呈现什么视图，它都能正常工作。我该怎么做才能使我的博客应用程序可以在任何视图中工作？欢迎所有帮助或建议。

Answer 1

我认为这很容易。给搜索一个专门的视图函数和一个对应的url就可以了，比方说：

url(r'^post-search/$', views.post_search, name='post-search')

然后您将当前的搜索表单放入 base.html，并更改指向 post-search url:

的表单操作

<form method="GET" action="{% url 'post-search' %}"  class="navbar-form navbar-right">
    <!-- same content goes here -->
</form>

所以现在每次你提交这个表单，它总是会去执行视图函数post_search你做同样的过程并显示结果。
