Better cleaner way to add ID/Class to Rails link_to?

New-ish to Rails... I've created a helper to format race names & their dates. I need to pass :id => "current-race" if a condition is present (basically if event is happening now). How could I go about this?

def formatted_race_dates(race)
    link_to (race.homepage) do
      raw("<strong>#{}</strong> <em>#{race_dates_as_string(race)}</em>")

now when race.start_date < && race.end_date > I'd like to add id="current-race" to the link.

I would normally set up an if/else condition and format it two ways. But seems there must be a Ruby trick I don't know to simplify something as common adding of a id/class to one link_to in a list? Even without the condition I'm not quite sure where/how to add :id => "current-race".

So many Ruby/Rails tricks I don't know...everything helps!


The link_to method takes options for this very reason:

link_to(race.homepage, :id => 'current-race') do ...

You can even add conditions to trigger it selectively:

link_to(race.homepage, :id => (race.start_date < && race.end_date > ? 'current-race' : nil) do ...

You can even collapse this if you have a method for Race that indicates if it's current:

link_to(race.homepage, :id => race.current? ? 'current-race' : nil) do ...

This is easily implemented in your model and can be used in other places:

def current?
  self.start_date < && self.end_date >

Having it in the model makes it significantly easier to test.
