Hi, I use the following code in a view to show a list of states inside a
form but I get not result, I mean I get no errors nor the expected HTML
code that should be something like <select><option ...
@states = State.find(:all, :order => "name")
collection_select(:firm, :state_id, @states, :id, :name)
Can anyone please tell me why?

Are you wrapping the collection_select code in <%= %> tags?

Hi William, I''m a PHP developer and I''m testing RoR so I thought <% ... %> was right when writing more than one line of code! I just added "=" after "<%" and it worked. Thanks a lot! These are those little errors that can make you waste a lot of time!

No problem. <% %> should be around code that you do not want the output added to the rendered page (adding a dash at the end like -%> will suppress the newline) and <%= %> goes around code that will generate output to be included in the rendered page. Hope this helps you. Nik Nik wrote:> Hi William, > I''m a PHP developer and I''m testing RoR so I thought <% ... %> was right > when writing more than one line of code!
