Use in your template to display all flash messages that may be stored. For example, given you stored:
flash # => { :error => 'Please enter your name' :info => 'Do you see the fnords?' }
Then a flashbox would display:
<div class='flash' id='flash_error'>Please enter your name</div> <div class='flash' id='flash_info'>Do you see the fnords?</div>
This is designed to be customized permanently or per usage:
flashbox("<div class='flash_%key'>%value</div>")
Where any occurrence of %key and %value will be replaced by the actual contents of each element of flash
# File lib/ramaze/helper/flash.rb, line 53 def flashbox(tag = ancestral_trait[:flashbox]) flash.map{|key, *values| values.flatten.map do |value| tag.gsub(/%key/, key.to_s).gsub(/%value/, value.to_s) end }.flatten.join("\n") end
