Making existing fields translatable is not working with Django 2.1

Django 2.1.12 django-parler 2.0

Prerequisites:

1. Create a new project and app
2. Add a new model( to follow the migration guide at https://django-parler.readthedocs.io/en/stable/advanced/migrating.html): class MyModel(models.Model): name = models.CharField(max_length=123)
3. Create and run the migration with makemigration

Making existing fields translatable(like explained in the documentation https://django-parler.readthedocs.io/en/stable/advanced/migrating.html)

1. Change the model to :

class MyModel(TranslatableModel):
    name = models.CharField(max_length=123)

    translations = TranslatedFields(
          name=models.CharField(max_length=123),
    )

1. Create the migration with makemigration -> Error that the name field already exists( see https://github.com/django-parler/django-parler/issues/154 ) -> rename the TranslatedField to translations_t and create the migration
2. Run the migration with migrate … -> AttributeError:

type object ‘MyModel’ has no attribute ‘_parler_meta’

Whatever you do, you always receive the attribute error that the model does not contain the parler_meta attribute. I need to make some fields translatable, that existed before, but unfortunately, I cannot make it work

@floa93: See https://github.com/django-parler/django-parler/issues/157#issuecomment-534440366 for a workaround.
