Single Table Inheritance in rails6

Question

I have a problem related to Single Table Inheritance, and I have never used it, can you guys help me?

Deck model

name: string
has_many Content
Content has 2 types: Content::ForTerm / Content::ForPhrase
Content::ForTerm has many Term
Content::ForPhrase has many Phrase

term model :

id, word, meaning, reading

phrase model :

id, sentence

Answer 1

Create a model class with class name as Content and two other child class as Term and Phrase which must be inherited from class Content

syntax would be

# app/models/Content.rb
class Content < ApplicationRecord    
  #your code    
end

# app/models/term.rb
class Term < Content    
  #your code    
end

# app/models/phrase.rb
class Phrase < Content    
  #your code    
end
