Evaluating variables in Rails views -- help!

Hey,

This is because you are comparing a string to an integer - params[:id]
will be a string whereas p.id will be an integer.

The quick way around this is: if params[:id] == p.id.to_s

... but i'd recommend abstracting this to a helper. Something like
this:

in application helper:

def class_if_current(css_class, model)
   if params[:id] == model.id.to_s
     "class=\"#{css_class}\" "
   end
end

then in your view:

<li <%= class_if_current("current", p) %>>

Hope that helps,

Steve

Hi Matthew,

This is code in a view.

Which is why I replied as I did. It was my understanding that we did not have access to the params hash in view code. Just ran a test in my sandbox and found out I was mistaken. Sorry to have wasted your time.
