So I struggle with this with every little thing I try – passing parameters between the view, model and controller.  I never get it right the first 10 times, and just 10 minutes ago figured it out yet again, so I figure I’ll share it.

Here’s the tip – more so I can look it up next time I have a brain fade.

In the view :

create a link like this :

<a href=”<%= url_for :action => :show, :query => {:title => ‘CodeDog.net Rules’, ‘:author => ‘Jonathan’} %>”>

Then in the controller show method

def show
@title = @params['title']
@description = @params['description']
render :action => :show
end

And in our show.erb file simply display with the @variablename

<%= @title %>
<%= @author %>

Very simple. So simple in fact, I’ll forget it in a week.

Code it right
