django多查询筛选器-匹配1或2个字段

我有一个这样的模型：

class Result(models.Model):
    title = models.CharField(max_length=300)
    desc = models.TextField(max_length=800)
    url = models.CharField(max_length=200)
    rank = models.BigIntegerField()
    category = models.ForeignKey('Category')
    tags = TaggableManager()
    def __str__(self):
        return self.title
    class Meta:
        verbose_name_plural = "Risultati"

class Category(models.Model):
    title = models.CharField(max_length=300)
    slug = models.SlugField(null=True)
    def __str__(self):
        return self.title
    class Meta:
        verbose_name_plural = "Categorie"

及意见:

def search_form(request):
    return render(request, 'search.html')

def result(request):
    if 'q' in request.GET and request.GET['q']:
        q = request.GET['q']
        results = Result.objects.filter(tags__name__in=[q], desc__icontains=q).order_by('-rank')
        return render(request, 'results.html', {'results': results, 'query': q})
    else:
        return render(request, 'search.html', {'error': True})

def detail(request, result_id):
    try:
        result = Result.objects.get(pk=result_id)
    except Result.DoesNotExist:
        raise Http404("Nessun risultato :(")
    return render(request, 'detail.html', {'result': result})

我需要按filter、tags或desc搜索，我尝试连接filter（）。filter（）但什么都没有发生，错误在哪里？

将表达式链接到同一个

filter（）

或单独的表达式中，执行隐式

和

。如果要执行

或

或显式

和

，则需要使用

....filter(Q(tags__name__in=[q]) | Q(desc__icontains=q))....
