Question

如果我的问题已经存在，我会事先道歉，但我还没有找到。

有一个模型：

    class Artikul_cabinets(models.Model):
         artikul_cabinets = models.CharField(verbose_name="Артикул шкафа", max_length=20)
         title_cabinets = models.CharField(verbose_name="Описание шкафа", max_length=200)
         width_cabinets = models.ManyToManyField(Width_cabinets)
         depth_cabinets = models.ManyToManyField(Depth_cabinets)
         unit_cabinets = models.ManyToManyField(Unit_cabinets)
         weight_cabinets = models.ManyToManyField(Weight_cabinets)
         type_cabinets = models.ForeignKey(Type_cabinets, default=1)
         color_cabinets = models.ForeignKey(Color_cabinets)
         glass_cabinets = models.ManyToManyField(Glass_cabinets)

    class Meta:
         verbose_name_plural = "Артикул шкафа"

    def __str__(self):
         return self.artikul_cabinets

有必要在字段上进行选择

    glass_cabinets = models.ManyToManyField(Glass_cabinets)

选择如下：

    data = Artikul_cabinets.objects.filter(Q(glass_cabinets=perf) & 
                       Q(glass_cabinets=glass)

perf和glass具有不同值的变量。然后我返回到我的空QuerySet，尽管记录中存在参数'perf'和'glass'的数据库元素。

告诉我我做错了什么。

也尝试过：

    data = Artikul_cabinets.objects.filter(Q(glass_cabinets=perf),
                       Q(glass_cabinets=glass)

并且也没有用，但是如果你把运算符'|'条件或工作正确。

所以我认为你应该做Artikul_cabinets.objects.filter(glass_cabinets=perf).filter(glass_cabinets=glass‌)

使用django对象Q查询数据库与运算符＆amp;
