Can I make a flash like hash in rails?

Question

I'm a ruby/rails newbie and need to make a hash which can be manipulated anywhere in the rails application and can be accessed by all views just like the flash[:notice] hash. Is this possible?

This should work:

class ApplicationController < ActionController::Base
  def block
    @block ||= {}
  end
  helper_method :block
end

block[:foo] = "FOO"
block[:foo] #=> "FOO"

However, what you are trying to do is normally done with the help of content_for

Yes, you can do it. Any key/value pair can be stored in flash. for example,

     flash[:email] = 'abc@yahoo.com'
     flash[:username] = 'abc'
     flash[:xyz] = 'xyz'

These values can be accessed any where in controllers and views, just like flash[:notice] and flash[:error]
