Question

所以这是我的HTML。子类别将根据使用js选择的类别由选项填充。 home.html的：

<form method="GET" action="{% url 'searchapp:search' city category %}"
      class="form-inline row input-group" id="search">
    <select class="form-control " id="place" style="" name="city" title="City" required>
        <option>Choose a City...</option>
        <!--<option value="noida">Noida</option>-->
        <option value="delhi">Delhi/NCR</option>
        <option value="delhi" disabled>Coming Soon...</option>
    </select>

    {% csrf_token %}

    <select class="form-control " id="category" style="" onchange="subcat()"
            title="Category" name="category" required>
        <option value="none">Choose a category</option>
        <option value="aprl">Apparels & Clothing</option>
        <-- more options -->
    </select>

    <select class="form-control " id="ms" style="" name="subcateg" title="Sub-Category"
            required>
        <option value="none">Choose a category first.</option>
        <-- more options -->
    </select>
    <span class="input-group-btn " id="inputbutton">
        <button type="submit" class="btn btn-primary" id="butn">Find Vendors!</button>
    </span>
</form>

这是搜索表单操作的网址。
searchapp / urls.py

app_name = 'searchapp'

urlpatterns = [

    url(r'^(?P<city>[a-z]+)/(?P<category>[a-z]+)$', views.search, name='search'),
    # url(r'^$', views.search, name='search'),
]

homeapp / urls.py

app_name = 'home'

urlpatterns = [
    url(r'^$', views.index, name='index'),
]

现在这里是我要显示所选城市和类别的视图

searchapp / views.py

def search(request, city, category):
    # return render(request, 'homeapp/index.html')
    return HttpResponse('<h3>search detail for :'+str(city)+str(category)+'</h3>')

homeapp / views.py:

# Create your views here.
def index(request):
    return render(request, 'homeapp/index.html')

当我运行本地服务器并转到我的主页时，应显示该表单，但我得到此错误

Error

错误是：

请告诉我如何解决它？
