html 中表单为何总是无法向 django 的 url 传入数据

这是一个 get 表单

<h4>站内搜索</h4> <form action="/search/" method="get"> <div class="input-group"> <input class="form-control" type="text" name="q" placeholder="仅支持搜索文章题目" value="{{ request.GET.q }}"> <span class="input-group-btn"> <input class="btn btn-default" type="submit"> <span class="glyphicon glyphicon-search"></span> </span> </div> </form> 

django 的 url

url(r'^search/$', views.test_search), 

views

def test_search(request): q = request.GET.get("q") if q: category_post = article.objects.filter(title__icOntains=q).distinct() paginator = Paginator(category_post, 2) page = request.GET.get('page') try: category_post = paginator.page(page) except PageNotAnInteger: category_post = paginator.page(1) except EmptyPage: category_post = paginator.paginator(paginator.num_pages) if len(category_post) == 0: return render(request, 'category.html', {"category_post": category_post, 'error': True}) else: return render(request, 'category.html', {"category_post": category_post, 'error': False}) 

但是每次输入表单都给我返回一个空白页面 请问下这是怎么回事
