input: Write a function to create a Django model with a field for storing strings in multiple languages. Use the TransCharField or TransTextField subclasses of TransField depending on the widget needed. Implement the get_in_language and set_in_language methods to access the translations, and use the TransFormField class for form validation in admin and when using ModelForm. Ensure that the field uses the TransDbValue class to store translations in a dictionary format.
  
  
  class MultiLanguageModel(models.Model):
      name = TransCharField()
      description = TransTextField()
  
      def get_name_in_language(self, language):
          return self.name.get_in_language(language)
  
      def set_name_in_language(self, language, value):
          self.name.set_in_language(language, value)
  
      def get_description_in_language(self, language):
          return self.description.get_in_language(language)
  
      def set_description_in_language(self, language, value):
          self.description.set_in_language(language, value)
  
  
  assert isinstance(MultiLanguageModel.name, TransCharField) == True
  assert isinstance(MultiLanguageModel.description, TransTextField) == True
  assert callable(MultiLanguageModel.get_name_in_language) == True
  assert callable(MultiLanguageModel.set_name_in_language) == True
  assert callable(MultiLanguageModel.get_description_in_language) == True
  assert callable(MultiLanguageModel.set_description_in_language) == True
