Django 在预回迁相关（）中使用预回迁应用筛选器

我正在创建一个多语言项目。我使用2个模型来保存数据。对于模型1中的所有语言（如图像）和模型2中的文本都相同的字段，并将ForeignKey设置为模型1

class FidelityClubs(models.Model):
    image = models.ImageField(upload_to='admin/fidelity_clubs/')


class FidelityClubTexts(models.Model):
    title = models.CharField(max_length=255)
    content = RichTextField()
    language = models.ForeignKey('van_admin.Languages', on_delete=models.CASCADE, default='1')
    club = models.ForeignKey('van_admin.FidelityClubs', on_delete=models.CASCADE, related_name='texts')

有一种默认语言。所有内容将以默认语言（法语）提供。如果用户选择另一种语言，则我有该语言的搜索内容，如果该语言的内容不可用，则我必须以默认语言显示内容。我正在使用这个查询

fidelities = FidelityClubs.objects.all().prefetch_related(Prefetch('texts', FidelityClubTexts.objects.filter(language__code=lang_code)))

我通过API发送这些数据。这是显示这样的数据

{
            "image": "http://127.0.0.1:8000/media/admin/fidelity_clubs/logo-1.png",
            "texts": [
                {
                    "id": 9,
                    "title": "CosmetiCar en",
                    "content": "<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry&#39;s standard dummy text ever since the 1500s, CosmetiCar Informaton Lorem Ipsum is simply dummy text of the printing and typesetting industry. en</p>",
                    "language": 2,
                    "club": 13
                }
            ]
        },
        {
            "image": "http://127.0.0.1:8000/media/admin/fidelity_clubs/logo-2.png",
            "texts": []
        },

它以各种语言显示数据

            "image": "http://127.0.0.1:8000/media/admin/fidelity_clubs/logo-1.png",
            "texts": [

有人能帮忙吗？

对于您的情况，有一个更简单的解决方案，我强烈建议您使用该库。最酷的是它依赖于请求的

Accept Language

头，它将根据头中传递的语言代码返回文本，如果没有，它将返回到您设置的默认语言代码
