Question

I am facing this ugly duplication in order to display different confirmation message in my view.

<% if current_user.password.nil? and current_user.services.count == 1 %>
  <%= link_to "Disconnect #{service.provider.capitalize}", service, :confirm => 'Remove this service will delete your account, are you sure?', :method => :delete %>
<% else %>
  <%= link_to "Disconnect #{service.provider.capitalize}", service, :confirm => 'Are you sure you want to remove this authentication option?', :method => :delete %>
<% end %>

I would be pleased to know if there is a way to avoid this?

Thank you!

EDIT:

ActionView::Template::Error (/Users/benoit/rails_projects/website/app/views/services/index.html.erb:15: syntax error, unexpected ',', expecting ')'
...e this authentication option?', :method => :delete, :class =...
...                               ^):
    12:         <% for service in @services %>
    13:           <div class="service">
    14:             <%= image_tag "logo_#{service.provider}.png", :class => "left" %>
    15: <%= link_to "Disconnect #{service.provider.capitalize}", service, :confirm => current_user.password.nil? and current_user.services.count == 1 ? 'Remove this service will delete your account, are you sure?' : 'Are you sure you want to remove this authentication option?', :method => :delete, :class => "remove" %>
    16: 
    17:             <div class="clear"></div>
    18:           </div>

Just perform a :

<%= link_to "Disconnect #{service.provider.capitalize}", service, :confirm => current_user.password.nil? and current_user.services.count == 1 ? 'Remove this service will delete your account, are you sure?' : 'Are you sure you want to remove this authentication option?', :method => :delete, :class => "remove" %>

Or if you this to be more understandable :

<% confirm_message = current_user.password.nil? and current_user.services.count == 1 ? 'Remove this service will delete your account, are you sure?' : 'Are you sure you want to remove this authentication option?' %>

<%= link_to "Disconnect #{service.provider.capitalize}", service, :confirm => confirm_message, :method => :delete, :class => "remove" %>

I am using Ruby ternary operator, check it : http://invisibleblocks.wordpress.com/2007/06/11/rubys-other-ternary-operator/
