我正在django 2.0.1使用django-modeltranslation 0.12.2和django-mptt 0.9.0

当我尝试注册一个扩展的翻译模型时，MPTTModel我得到了这个错误：

我的models.py：

class Category(MPTTModel):
    name = models.CharField(max_length=128)
    slug = models.SlugField(max_length=50)
    description = models.TextField(blank=True)
    image = models.ImageField(upload_to=category_image_path, blank=True)
    has_variants = models.BooleanField(default=True)
    parent = TreeForeignKey(
        'self', null=True, blank=True, related_name='children',
        on_delete=models.CASCADE)

我的translation.py：

from modeltranslation.translator import register, TranslationOptions
from .models import Category

@register(Category)
class CategoryTranslationOptions(TranslationOptions):
    fields = ('name', 'description',)

我相信这个错误是由 和 之间的冲突引起TreeManager的MultilingualManager。我尝试将Category模型的管理器更改为默认值models.Manager，并且效果很好。
