      This function performs CRUD (Create, Read, Update, Delete) operations on a
      model instance using a Django-like ORM. The function takes in the model
      instance, the action (as a string) which can be 'create', 'read', 'update',
      or 'delete', and an optional name parameter for 'create', 'update', and 'delete'.
