Question

I have a model :

class Hotel < ActiveRecord::Base
   has_many :hotel_comments
end

In my controller, i get some hotels:

@hotels = Hotel.all

How can I get all comments for my hotel dictionary?

Thank you!

Guessing what you mean by “dictionary”:

Hash[Hotel.includes(:hotel_comments).map { |h| [h, h.hotel_comments] }]

If you just want all comments in a array:

Hotel.includes(:hotel_comments).map(&:hotel_comments).flatten(1)
