Question

If I have…

class Bunny < ActiveRecord::Base   has_many :carrots end 

…how can I check in the View if @bunny has any carrots? I want to do something like this:

<% if @bunny.carrots? %>   <strong>Yay! Carrots!</strong>   <% for carrot in @bunny.carrots %>     You got a <%=h carrot.color %> carrot!<br />   <% end %> <% end %> 

I know @bunny.carrots? doesn’t work — what would?

Answer 1

<% if @bunny.carrots.any? %>   <strong>Yay! Carrots!</strong>   <% for carrot in @bunny.carrots %>     You got a <%=h carrot.color %> carrot!<br />   <% end %> <% end %>
