Forms within other object views

I'm sure I'm overlooking something really obvious, but I'm trying to figure out how to do a form for an object associated with the current view object.

Specifically, I have an itinerary that has events. When I'm looking at an itinerary I should be able to add new events. My relationship between the two is:

class Itinerary < ActiveRecord::Base   has_many :event end

class Event < ActiveRecord::Base   has_one :itinerary end

In the itineraries_controller, I have a show method defined like this:

  def show     @itinerary = Itinerary.find(params[:id])

    @new_event = Event.new   end

However, it is clearly puking on the Event.new, and I'm looking for a good place to learn about how to work through all of these associations. If this isn't the place, I'd love a link to where this is taught.

Thanks in advance.

So I've updated my show method to look like:

  def show     @itinerary = Itinerary.find(params[:id])     @new_event = @itinerary.events.build   end

but still no luck.

Thanks again.

Got it.

I had a has_one relationship where I needed a belongs_to relationship.

Thanks interwebs :slight_smile:
