Django admin ignores dynamically generated form fields

[Random Body Parts]

I'm trying to have the django admin display a model form with dynamically generated fields. I setup my form like this:

class EulogyTextForm(f.ModelForm):
    class Meta:
        model = EulogyText
        fields = '__all__'

    def __init__(self, *args, **kwargs):
        super(EulogyTextForm, self).__init__(*args, **kwargs)

        for i in range(len(settings.MULTITEXT_LANGUAGES)):
            field_name = 'language%s' % (i, )
            self.base_fields[field_name] = f.CharField(disabled=True, initial=settings.MULTITEXT_CHOICES[i][0])
            field_name += '_text'
            self.base_fields[field_name] = f.CharField()

I have setup my admin like this:

class EulogyTextAdmin(admin.ModelAdmin):
    model = EulogyText

    exclude = []

    form = EulogyTextForm

However, Django admin will not display my added fields. I have created a TestView to display the form. In the test view, the form is correctly displayed with the added fields. Why does Django admin ignore the additional fields?
