我有一个模型：

class Tasks(models.Model):
    name = models.CharField(max_length = 50, null = True, blank = True)
    assigned_to = models.ManyToManyField(User, null = True, blank = True)

我必须执行一个查询

tasks_for_myuser = Tasks.objects.filter(assigend_to__contains = myuser)

但这会引发错误。 django.core.exceptions.FieldError: Related Field got invalid lookup: contains

请帮忙！
