Hi

I am now trying to learn some rails tag and encounter one question on "select" tag.

== Controller

def post_book     @book = Book.new(:type => "CS") end

== Viewer

<%=select "book", "type", [                                   [" tale", "T"],                                   ["computer science" ,"CS"]...                                   ],                                   {....}                                   %> When I open the page xxx/yyy/post_book, it throws exception: wrong argument type String (expected Module). And the exception occured line number is the "select" tag. So could you please tell me how to solve the problem?

---- I don't recall ever setting values that way but I don't always do shortest code...

def post_book   @book = Book.new   @book.type = "CS" end

but I wonder if 'type' is a bad name for a field (reserved word?) and would probably use btype or book_type just in case

Craig, thanks for your reminder! it works now :slight_smile:
