It's well described in Django FAQ:

Q: How do I change the attributes for a widget on a field in my model?

A: Override the formfield_for_dbfield in the ModelAdmin/StackedInline/TabularInline class

class MyOtherModelInline(admin.StackedInline):
    model = MyOtherModel
    extra = 1

    def formfield_for_dbfield(self, db_field, **kwargs):
        # This method will turn all TextFields into giant TextFields
        if isinstance(db_field, models.TextField):
            return forms.CharField(widget=forms.Textarea(attrs={'cols': 130, 'rows':30, 'class': 'docx'}))
        return super(MyOtherModelInline, self).formfield_for_dbfield(db_field, **kwargs)
