How to get array values in Ruby On Rails

I am working on Localization concept in Rails and need to get some of the localization values in HTML pages. So i generated array in controller like below format.,

#array use to store all localization values 
@alertMessages = []

#array values...
{:index=>"wakeUp", :value=>"Wake Up"}
{:index=>"tokenExpired", :value=>"Token Expired"}
{:index=>"timeZone", :value=>"Time Zone"}
{:index=>"updating", :value=>"Updating"}
{:index=>"loadMore", :value=>"Load More"} 
#....more

In HTML pages i want to get localization values like below or some other type,

<%= @alertMessages['wakeUp'] %>

so, it will display value is 'Wake Up',

But its not working.. Can any one please...

It's easier to use a hash for this (http://api.rubyonrails.org/classes/Hash.html), which is like an array with named indexes (or keys).

So do this:

@alert_messages = {
   wake_up: "Wake Up",
   token_expired: "Token Expired",
   .
   .
   .
}

you can also extend your hash this way:

@alertMessages[:loadMore] = "Load More"

Access it by using:

@alert_messages[:loadMore]

Also you should check i18n to do Internationalization, which is a more robust and flexible way: http://guides.rubyonrails.org/i18n.html

try this:

<% 
    @alertMessages.each_with_index do |alertMessage, index|
    alertMessage[:value] if index == "wakeUp"
    end 
%>

Thanks.

# Hash to store values
@alertMessages = {}

#hashvalues...
alertMessages[:wakeUp] = "Wake Up"
alertMessages[:tokenExpired] = "Token Expired"
alertMessages[:timeZone] = "Time Zone"
alertMessages[:updating] = "Updating"
alertMessages[:loadMore] = "Load More"

#....more
In HTML pages i want to get localization values like below or some other type,

<%= @alertMessages[:wakeUp] %>
so, it will display value is 'Wake Up',

And try to use always symbols because lookup will be fast

An array doesn't seem really appropriate here but if you still want to use it, proceed ths way:

array.find{|el| el[:index] == "wakeUp"}[:value]

You should abstract this though.
