Why does this rescue syntax work?

Ok so I have this method of an application I am working with and it works in production. My question why does this work? Is this new Ruby syntax?

def edit
  load_elements(current_user) unless current_user.role?(:admin)

  respond_to do |format|
    format.json { render :json => @user }   
    format.xml  { render :xml => @user }
    format.html
  end

rescue ActiveRecord::RecordNotFound
  respond_to_not_found(:json, :xml, :html)
end
Solution

  • rescues do not need to be tied to an explicit begin when they're in a method, that's just the way the syntax is defined. For examples, see #19 here and this SO question, as well as the dupe above.
