Hello Everyone
I have a select_tag which I populate using a map, I use
options_for_select method to pass the map and “selected” value. For some
reason I can not get the option “selected” based on the value I pass to
the selected attribute. Here is the code
<%= select_tag :current_course,
options_for_select( Course.find(:all).map {|p| [p.title,p.id]},
@selected )
%>
The corresponding HTML produced is
Mathematics I Engineering Design Technical WritingWhen I printed the value of @selected variable, it is either 1,2 or 3.
But I never get any option selected.
Interestingly if instead of passing @selected, I pass 1, 2 or 3 as in
the code below
<%= select_tag :current_course,
options_for_select( Course.find(:all).map {|p| [p.title,p.id]},
2 )
%>
I DO GET 2nd option selected.
I am wondering, if I am doing anything wrong passing a variable as
“selected” attributed in options_for_select method.
Any help or suggestions would really be appreciated.
Thanks
