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?
