我们有：
在模型.py
class Language(models.IntegerChoices):
en = 1
ru = 2
class Translation(models.Model):
language_id = models.PositiveIntegerField(choices=Language.choices)
mnemonic = models.CharField(max_length=255)
translation = models.CharField(max_length=255)
- 在 serializers.py 中
66 def get_translations(self, obj):
67 language: int = self.initial_data.get('language') or settings.SERVER['current_language_id']
68 common_public = Translation.objects.filter(language_id=language).exclude(mnemonic__startswith='dictionary')
当我通过 mypy 检查它时：
resources/serializers.py:67：错误：赋值中的类型不兼容（表达式的类型为“Union [Any, object]”，变量的类型为“int”）
- 如果在 serializers.py
66 def get_translations(self, obj):
67 language: Union[Any, object] = self.initial_data.get('language') or settings.SERVER['current_language_id']
68 common_public = Translation.objects.filter(language_id=language).exclude(mnemonic__startswith='dictionary')
通过 mypy 检查它：
资源/serializers.py:68：错误：查找'language_id'的类型不兼容：（得到“Union [Any，object]”，预期“Union [str，int]”）
3)
66 def get_translations(self, obj):
67 language: Union[str, int] = self.initial_data.get('language') or settings.SERVER['current_language_id']
68 common_public = Translation.objects.filter(language_id=language).exclude(mnemonic__startswith='dictionary')
核实：
resources/serializers.py:67：错误：赋值中的类型不兼容（表达式的类型为“Union[Any, object]”，变量的类型为“Union[str, int]”）
怎么了？
