Conditionally set method options?

Question

Is there a way to conditionally set options for a method?

Something like...

article_url(@article, :host => 'myblog.com' if @user.custom_domain?)

So in that case...only setting host if the user has a certain option set for their account.

Answer 1

opts = @user.custom_domain? ? {:host => 'myblog.com'} : {}
article_url @article, opts

Or a one liner:

article_url @article, @user.custom_domain? ? {:host => 'myblog.com'} : {}
