如何使用postgres在Django中获取arrayfield数据

Question

I'm trying to fetch users list based on their language(from ArrayField). A single user can have multiple languages. When i passed single language {'Hindi'} , it fetches all the records except user with multiple languages, but if passed parameters {'Hindi','bangla','kannada'} then it gives me a specific record,how can i fetch the users list with hindi and other than hindi as well . I have tried with .all also but it didn't worked for me. Any help would be appreciated.

models.py

# DESCRIPTION: This function gets the drivers list by lang.
    @classmethod
    def get_driver_by_lang(cls, driver_lang):
        try:
            driver_details = cls.objects.filter(language = driver_lang)
            data = serializers.serialize("json", driver_details)
            data = json.loads(data)
            return data
        except :
            return False

Answer 1

这个怎么样：

driver_details = cls.objects.filter(language__contains = driver_lang)
