Field name with "-"

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? /usr/lib64/ruby/gems/1.9.1/gems/activerecord-2.3.8/lib/active_record/attribute_methods.rb:1: syntax error, unexpected '-', expecting ';' or '\n' def session-timers; missing_attribute('se...             ^ /usr/lib64/ruby/gems/1.9.1/gems/activerecord-2.3.8/lib/active_record/attribute_methods.rb:1: syntax error, unexpected keyword_end, expecting $end ...tributes['session-timers']; end ... ^ Exception occurred during reader method compilation.

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.
