I am trying to figure out how to use the “select” helper in changing a  
scaffold produced “new.html.erb” file. Specifically how do I change:

Year In School: \<%= f.text\_field :year %\>

so that this shows up as a “drop down box”.

I’ve tried different variations of

\<%= f.select :year %\>

but that never works.  
Any help?

Nope, that doesn’t work. To clarify, the year part is supposed to be a  
pull down select menu of “Senior, Junior, Sophomore, Freshman”

\<%= select :obj,:year ,%w{Senior Junior Sophomore Freshman} %\>
