modeltranslation and proxy models

[Andre Nitschke]

Hy,

in first sorry for my bad english,

i use the new 0.9 version of django-modeltranslation with the latest checkout from django v1.8. Since i had upgraded have problems with my categories app based on django-mptt. 

I have an base category class for mptt-handling and 2 proxy models based on it for trees and the categories

for example:

models.py

class BaseCategory(MPTTModel):

    name = models.CharField(_('name'), max_length=255)

    ...

class CategoryTree(BaseCategory):

    class Meta:

        proxy = True

class Category(BaseCategory):

    class Meta:

        proxy = True

translation.py

class BaseTransOpts(TranslationOptions):

    fields = ('name',)

translator.register(BaseCategory, BaseTransOpts)

translator.register(CategoryTree, BaseTransOpts)

translator.register(Category, BaseTransOpts)

The Problem is in DjangoAdminClasses for the proxy models the fields which should translated are not available. When i set it explizit in fields property of TranslationAdmin i get an FieldError:

Unknown field(s) (name_de) specified for CategoryTree. Check fields/fieldsets/exclude attributes of class CategoryTreeAdmin

Also when i set name in list_display property i get a NoneType Error

I have check the problem over the python-shell. When i ask the Meta-Api with get_fields() the TranslationFields are listed but when i try to get the field with get_field('name_de') - i get an FieldDoesNotExist Exception.

Also when try with print the value - i get an 'object has no attribute 'name_de' Exception.

I have create an TranslationAdminClass for the BaseCategory-Model for testing, there are no problems.

What can i do?
