How to display a column of options from a table into a drop down

change the CSS whitespace property. I would recommend formatting the
text field for display with simple_format(text). Read about it here: ActionView::Helpers::TextHelper

that is some kind of plugin…could you please give link to some tutorial
on how to use that because I learned user authentication just a couple
of hours ago
I would definitely suggest that you familiarize yourself with the
basic concept of user authentication in rails before you start using a
plugin (so that you understand what the plugin does). The Agile Web
Dev. with Rails book has a user authentication section that goes over
it briefly. The restful_authentication plugin itself has excellent
README and RDoc documentation and the code is quite easy to follow as
well, so you may want to check it out. (the plugin is in
technoweenie’s plugin repository, google should find it for you
easily, and there are various resources online that can help you
integrate it, including a wiki for the original acts_as_authenticated
plugin)
It sounds like his get params are fubared. 4 is probably the id he
wants but he’s put it in the action param instead. Of course 4 could
also be the id of nil, but we’ve got whiny nils to prevent that
confusion.
Default rails routing is :controller/:action/:id which means that http://localhost:3000/post/4 gives the params { :controller =>
‘post’, :action => ‘4’, :id => nil }
You want params like { :controller => ‘post’, :action => ‘index’, :id
=> ‘4’ }
