我試圖在我的搜索模板中實(shí)現(xiàn)一些基本搜索，但是當(dāng)我搜索時(shí)，它在 URL 中工作，但不會(huì)更改模板中的任何帖子。意見：class SearchListView(ListView): model = Post template_name = "public/search.html" def get_context_data(self, **kwargs): context = super(SearchListView, self).get_context_data(**kwargs) context['queryset'] = Post.objects.filter(live=True) context['category'] = Category.objects.all() return context def SearchListView(request): query = self.request.GET.get("q") if query: queryset = queryset.filter(title_icontains=query)我不確定這是否是正確的設(shè)置方式，因?yàn)槲艺谟^看的教程沒有使用基于類的視圖。HTML：<div class="container mt-5 mb-5"> <div class="banner-search-main mb-5"> <form method='GET' action=''> <p class="text-muted">Keywords:</p> <input type="text" name='q' class="homebanner-search" placeholder="Enter your keywords" value='{{ request.get.q }}'> <input type="submit" value="search"> </form> </div> <div class="detail-container"> {% for post in queryset %} <div class="col-sm card-container"> <a href="{% url 'post-detail' post.slug %}"> <div class="main-card"> <div class="main-card-img"> <img src="https://via.placeholder.com/270x150" class="card-img-top" alt="#"> </div> </div> </a> </div> {% endfor %} </div></div>例子：

帶有 get_queryset 方法的 ListView
class SearchListView(ListView):
model = Post
template_name = "public/search.html"
def get_queryset(self):
queryset = super().get_queryset().filter(live=True)
query = self.request.GET.get("q")
if query:
queryset = queryset.filter(title__icontains=query)
return queryset
def get_context_data(self, **kwargs):
context = super(SearchListView, self).get_context_data(**kwargs)
context['queryset'] = self.get_queryset()
context['category'] = Category.objects.all()
return context

首先，我建議訪問這個(gè)以查看基于類的視圖的基礎(chǔ)結(jié)構(gòu)。
class SearchListView(ListView):
model = Post
template_name = "public/search.html"
success_url ='where you want to redirect'
def get_queryset(self): # method that returns the queryset is `get_queryset`
query = self.request.GET.get("q")
if query:
queryset = self.model.objects.filter(title__icontains=query) # double underscore not single
return queryset
def get_context_data(self, **kwargs):
context = super(SearchListView, self).get_context_data(**kwargs)
context['queryset'] = self.get_queryset()
context['category'] = Category.objects.all()
return context

您的問題是您在類中創(chuàng)建了一個(gè)隨機(jī)函數(shù)，該函數(shù)不會(huì)覆蓋任何內(nèi)容。您要做的是覆蓋get_queryset()。
class SearchListView(ListView):
model = Post
template_name = "public/search.html"
def get_context_data(self, **kwargs):
context = super(SearchListView, self).get_context_data(**kwargs)
context['queryset'] = self.get_queryset()
context['category'] = Category.objects.all()
return context
def get_queryset(self):
queryset = super().get_queryset().filter(live=True)
query = self.request.GET.get("q")
if query:
queryset = queryset.filter(title__icontains=query)
return queryset
