I'm trying to display a delete button only if the current user is the "host" but the button is hidden even if the user id for the host matches the user id for the guest
<%= link_to "X" , "/songs?name=#{s.name}&party_profile_id=#{s.party_profile_id}&commit=X", :remote => true, :class => "btn btn-inverse btn-small refreshbutton", :style => "display:none" unless @current_user.id == @party_profile.host %>
Am I using the wrong syntax? Is there a better way to conditionally display items?
You could switch to only render it, rather than toggling the css class (unless your application would need to toggle it client side for some reason).
<% if @current_user.id == @party_profile.host %>
<%= link_to "X" , "/songs?name=#{s.name}&party_profile_id=#{s.party_profile_id}&commit=X", :remote => true %>
<% end %>
Your condition would apply to the link itself, not the style attribute.
Do this instead:
<%= link_to "X" , "/songs?name=#{s.name}&party_profile_id=#{s.party_profile_id}&commit=X", :remote => true, :class => "btn btn-inverse btn-small refreshbutton", :style => "#{'display:none;' unless @current_user.id == @party_profile.host}" %>
shouldn't it be
if @current_user.id == @party_profile.host ?
Edit:
you don't need to set the style to display none. The if statement will handle whether it is rendered in the view.
@party_profile.hostan integer, because@current_user.idalmost certainly is, and I wonder if they can ever be the same thing.
