How to use Ransack Aliases

Question

I am trying to implement aliases with Ransack to make my URL search query shorter.

According to the docs: https://github.com/activerecord-hackery/ransack#ransack-aliases

class Post < ActiveRecord::Base
  belongs_to :author

  # Abbreviate :author_first_name_or_author_last_name to :author
  ransack_alias :author, :author_first_name_or_author_last_name
end

However when i use it in my model, i get a

undefined method `ransack_alias' for #<Class:0x007f9376f176e0> 

Answer 1

You should use the latest updates, use the master branch.

gem 'ransack', github: 'activerecord-hackery/ransack'

Answer 2

As I understand, ransack_alias appeared in the master branch of the ransack, in 1.7.0(current stable) it was not implemented.

Answer 3

method ransack_alias was appeared in v 1.8.0

Ransack 1.8.0 changelog
