Simple string comparasons

Rails

Hey Everyone I’m caught up on some data output.

this is what i currently have:

Make:
<%=h vehicle.make %>
Model:
<%=h vehicle.model %>
Year:
<%=h vehicle.year %>
Mileage:
<%=h vehicle.mileage %>
<% if vehicle.vehicle_options.drive.eql? "please_select" %>
  <dt>Transmission:</dt><dd><%=h

vehicle.vehicle_options.transmission
%>
<% end %>

<% if vehicle.exterior_color.eql? "not_specified" %>
  <dt>Ext Color:</dt><dd><%=h vehicle.exterior_color %></dd>
<% end %>
<% if vehicle.vehicle_options.drive.eql? "please_select" %>
  <dt>Drivetrain:</dt><dd><%=h vehicle.vehicle_options.drive %></dd>
<% end %>
<% if vehicle.vehicle_options.engine_size.eql? "" %>
  <dt>Engine:</dt><dd><%=h vehicle.vehicle_options.engine_size %></

dd>
<% end %>

Price:
<%=h vehicle.price %>

I have some enumerated fields on creation and I don’t want to display
them in the event someone has decided not to fill them out (ie leaving
them as the default). The above does not work sadly. How can I
appropriatly check for this. I also have some boolean values as well
as possible nils(Or blank space). How can I check for these and if
theres content display it. Otherwise skip that whole field ?

I figure it should be pretty easy but everything I try fails.

Thanks, Happy Holidays !
