我可以使用一个搜索栏来搜索不同的东西吗？

Question

我正在尝试使用单个搜索栏来搜索不同的模型。是否可以一视同仁？

我的views.py文件：

class SearchResultsView(ListView):
    model = Food
    template_name = 'restaurant/food_search_results.html'
    context_object_name = 'data'

    def get_queryset(self):
        query = self.request.GET.get('search')
        if query is not None:
            return Food.objects.filter(name__icontains=query)
        else:
            return Food.objects.none()

我的 models.py 文件：

class Food(models.Model):

    name = models.CharField(max_length=100)
    image = models.ImageField(upload_to=upload_path)
    description = models.TextField(max_length=500)
    created = models.DateTimeField(auto_now_add=True)

    meal_category = models.ManyToManyField(MealCategory, related_name="meal")
    food_restaurant_category = models.ManyToManyField(FoodRestaurantCategory, related_name="food_cat")

class Restaurant(models.Model):
    name = models.CharField(max_length=100)

您可以使用上下文传递第二个模型筛选列表：

class SearchResultsView(ListView):
    model = Food
    template_name = 'restaurant/food_search_results.html'
    context_object_name = 'data'

    def get_queryset(self):
        query = self.request.GET.get('search')
        if query is not None:
            return Food.objects.filter(name__icontains=query)
        else:
            return Food.objects.none()
        
    def get_context_data(self, **kwargs):
        query = self.request.GET.get('search')
        context = super(SearchResultsView, self).get_context_data(**kwargs)
        if query is not None:
            filtered_restaurants= Restaurant.objects.filter(name__icontains=query)
        else:
            filtered_restaurants= Restaurant.objects.none()

        context.update({
            'restaurants_list': filtered_restaurants
        })
        return context

Can I use a single search bar for searching different things?
