Django access same attribute on different model dynamically

I have different models which has following format.

class Company(models.Model):
    pass

class ModelA(models.Model):
    company = models.ForeignKey(Company, models.CASCADE)

class ModelB(models.Model):
    company = models.ForeignKey(Company, models.CASCADE)

class ModelC(models.Model):
     modelb = models.ForeginKey(ModelC)

I want to write generic display field by the use of mixin in django admin for ModelA, ModelC as:

class FieldMixin:
  @display(description='field')
  def my_field(self, obj):
      # normal solution would be this
      if object is ModelA and object.company.is_active:
         return 'active'
      if object is ModelC and object.modelb.company.is_active
         return 'active'
      
      # i wanted something like this instead of above. It will be easier if object has immediate attribute but object can have same field in nested object as well.
      object._meta.get_fields('company').is_active
