Question

I created a model called UserHasMessages based on some SO postings. I think this seems to be creating some challenges for me:

• How do I reference it with has_many? Should I use has_many :user_has_messageses?

• How do I do joins? I have tried User.joins(:user_has_messages) and it is sad 🙁

Question:

Should I somehow change the name to UserHasMessage, and if so, how?

If I keep as plural, how do I handle these cases?

Answer 1

You could add a new migration

rails g migration rename_user_has_messages

inside it you write:

class RenameUserHasMessages < ActiveRecord::Migration
  def self.up
    rename_table :user_has_messages, :user_messages
  end

  def self.down
    rename_table :user_messages, :user_has_messages
  end
end

(the table is always plural)

Run the migration.

Rename your file from user_has_messages.rb to user_message.rb, and rename your class from UserHasMessages to UserMessage.

Done 🙂
