Field name with "-"

Rails
1

Hello.

I’m tryes to write webGUI for application’s database. This application
uses pre-defined field names, for i.e. “session-timers” and I can’t
change its.

In the users.rb writes:

def index
@sipusers=User.all
end

In the index.html.erb:

<% @users.each do |user| %>
<%=h user[“session-timers”]%>
<%end%>

It’s work fine but servers output:

Exception occurred during reader method compilation.
Maybe session-timers is not a valid Ruby identifier?

  1. How can I remove this errors? Maybe ActiveRecord can create alias for
    any name?

  2. How can I use helpers (.text_field. .label and etc) for inserting
    data from web page?

Thanks for answers.
