input: Write a function to create a translation field for storing a string in multiple languages in a Django model. Use the TransCharField or TransTextField subclass of TransField depending on the widget needed. Use the TransDbValue class to store the translations in a dictionary format and implement the get_in_language and set_in_language methods to access the translations. Use the TransFormField class for form validation in admin and when using ModelForm.
  assert create_translation_field(TransCharField) == "TransCharField(max_length=100)"
  assert create_translation_field(TransTextField) == "TransTextField()"
  assert create_translation_field(None) == ""
  assert create_translation_field("InvalidField") == ""
output: def create_translation_field(field_type):
      if field_type == TransCharField:
          return "TransCharField(max_length=100)"
      elif field_type == TransTextField:
          return "TransTextField()"
      else:
          return ""
