Params2session

• To simplify common patterns, related to saving session variables.
• To store variables in "per-controller scope". For example, in UsersController, calling session_save(:mode) will save params[:mode] to session['users.mode']

Add this line to your application's Gemfile:

gem 'params2session'

Then execute:

bundle

This gem can be used in two or more steps:

• Save variable from params to session
• (optional) Set default value
• Get variable from session

In controller:

session_save :mode
do_some_stuff if session_param(:mode)

Or:

session_save :mode
session_default :mode, 'all'
do_some_stuff if session_equal?(:mode, 'none')

Or:

session_save :mode
session_update(:mode, 'all') if session_param(':mode') == 'none'
do_some_stuff if session_equal(:mode, 'some')

session_param and session_equal? helpers are also available in views.

session_equial?(param_name, value) can be used in views to set class on buttons or button groups depending on saved param state, or to render different partial based on saved param.
