RememberParams

Rails gem that makes actions remember GET params like keywords and page.

Say you have that index action where you can search, filter and paginate through records. Once you click on one of the records you lose track of the exact location (e.g. search keywords, filter settings or page).

RememberParams will bring users back to that exact location when they return to the index page by remembering the search keywords, filter settings and page.

To make a controller action remember its params simply add the remember_params line on top like this:

class BooksController < ApplicationController
  remember_params :keywords, :page # defaults are on: index and duration: 1.hour
  remember_params :client_id, on: :client_list, duration: 1.minute
end

Browsing the action without any params will automatically try to restore params and redirect to the same route but with previously set params.

If for example you have the keywords params remembered and follow a link with only a page param, the remembered keywords param and the newly set page param will be mixed.

Reset all remembered params like this:

link_to 'Books', books_path(reset_params: true)

You can also mix reset_params and setting new params.

link_to 'Books', books_path(reset_params: true, page: 2)

Add this line to your application's Gemfile:

gem 'remember_params'

And then execute:

$ bundle

Or install it yourself as:

$ gem install remember_params
