Python django models.py使用外部字段排序

我使用的是django1.7，我有两个模型

在我的一个模型中，我希望通过外部模型上的字段指定。这两个模型由外键链接

以下是我的两个示例模型：

class ObjectiveDetails(models.Model, FillableModelWithLanguageVersion):
    user = models.ForeignKey(User)
    language_version = models.ForeignKey('LanguageVersion')
    field = models.TextField(null=False, blank=False, max_length=5000)
    objective_timestamp_added = models.DateTimeField(auto_now_add=True, auto_now=False)
    objective_timestamp_updated = models.DateTimeField(auto_now=True, auto_now_add=False)

    class Meta:
        ordering = ['language_version.language_code', 'id']

class LanguageVersion(models.Model):
    """Language version selection for a user"""
    user = models.ForeignKey(User)
    language_code = models.CharField(max_length=32)
    language_code_disabled = models.BooleanField(default=False)
    language_version_timestamp_added = models.DateTimeField(auto_now_add=True, auto_now=False)
    language_version_timestamp_updated = models.DateTimeField(auto_now=True, auto_now_add=False)  # the date the language version is updated when the user changes their subscription type.

我正试图按照LanguageVersion模型上的语言代码对ObjectiveDetails进行排序。

我试了好几次，但都做不好。我已经阅读了文档并搜索了SO和Google，但找不到正确答案，

将按语言排序的代码添加到语言版本，并从客观细节中删除.language\u代码

您添加的每个外键都将 还隐式地包含其所有默认顺序

你的模特会是这样的

class ObjectiveDetails(models.Model, FillableModelWithLanguageVersion):
    user = models.ForeignKey(User)
    language_version = models.ForeignKey('LanguageVersion')
    field = models.TextField(null=False, blank=False, max_length=5000)
    objective_timestamp_added = models.DateTimeField(auto_now_add=True, auto_now=False)
    objective_timestamp_updated = models.DateTimeField(auto_now=True, auto_now_add=False)

    class Meta:
        ordering = ['language_version', 'id']

class LanguageVersion(models.Model):
    """Language version selection for a user"""
    user = models.ForeignKey(User)
    language_code = models.CharField(max_length=32)
    language_code_disabled = models.BooleanField(default=False)
    language_version_timestamp_added = models.DateTimeField(auto_now_add=True, auto_now=False)
    language_version_timestamp_updated = models.DateTimeField(auto_now=True, auto_now_add=False)  # the date the language version is updated when the user changes their subscription type.

    class Meta:
        ordering = ['language_code']

你试过按（‘语言版本’）订购吗？？德蒙诺，谢谢，效果很好-我有点不好意思，我错过了。
