Two more dumb noob questions

Rails
1

Hello all,
Sorry for flooding the list with silly questions lately, but I’m having
some difficulty with some basic concepts in Rails.

  1. What is the difference between an item prefixed with a colon and one
    without (as in :class => “test” vs class => test). I think there’s a
    major concept I’m missing out on here, as this problem nails me
    frequently.
  2. How in the world do I make an image link? I know how to do it in
    HTML, but how the heck do I nest calls to helpers? In this case I’d be
    using the <%= image_tag … %> inside of a <%link_to…%>. How do I do
    this?

Thanks,
Will

An item prefixed with a colon is a symbol. It’s sort of like a string.
“class” => “test”, :class => “test”, etc. Without a colon prefixed, it
would
be a variable.

<%= link_to image_tag(“image.jpg”), :controller => ‘main’, :action =>
‘index’ %>
just like,
<%= link_to “Text”, :controller => ‘main’, :action => ‘index’ %>

Just replace the text that you want to link to with your image_tag.

You might want to read a few basic texts on Ruby before starting out.
Why’s
guide is a good intro (and fun), or the first edition of the Pickaxe is
also
available online, and it provides a good enough “textbookish” coverage.
