djongo EmbeddedField with Django Admin

One line description of the issue

I'm trying use EmbeddedField. Perhaps an I do a mistake?

Python script

from djongo import models


class Language(models.Model):
    CODE_LANG_CHOICES = (
        ('en', 'English'),
        ('pt', 'Portuguese'),
    )

    DIRECTION_CHOICES = (
        ('ltr', 'Left-to-right'),
        ('rtl', 'Right-to-left'),
    )

    code = models.CharField(max_length=2, choices=CODE_LANG_CHOICES, default='en')
    direction = models.CharField(max_length=3, choices=DIRECTION_CHOICES, default='ltr')

    def __str__(self):
        return f'{self.code}'

    class Meta:
        abstract = True


class Campaign(models.Model):
    name = models.TextField()
    language = models.EmbeddedField(model_container=Language)

@drandredev put in your requirements.txt the version of 1.3.1 of Djongo.

Same problem here too. I get Abstract models cannot be instantiated. on the admin site.

Downgrading djongo to 1.3.1 does not help me as my project is on Django 3.1.12, and djongo 1.3.1 requires Django version<2, Please suggest some fix.

I still have this issue and am running djongo 1.3.6.

@brunowego This is occurring for me except with lists using djongo 1.3.6. My version of django (3.1.2) won't allow for me to downgrade djongo. Is anyone on this, yet?
