Question

So I have an observer which looks like this:

class RecipeObserver < Mongoid::Observer

  def after_create(object)
    puts object.user
    puts "test"
  end

end

And so I have that working fine, but the relationship object.user is nil, like even though my Recipe class belongs_to a user, which has_many recipes as well. What am I doing wrong here?

---

Update

So here is my controller code and my model, if someone could please show me how a proper observer that creates another object works, that would be very helpful:

class RecipesController < ApplicationController
  respond_to :html
  before_filter :authenticate_user!, :only => :new

  # ... other actions

  def new
    @recipe = Recipe.new
    respond_with @recipe
  end

  def create
    @recipe = Recipe.new(params[:recipe])
    @recipe.save

    respond_with @recipe, :notice => "You've created a recipe!"
  end
end

My models (truncated for brevity):

class Recipe
  include Mongoid::Document

  # ... other methods and such

  belongs_to :user
end

class User
  include Mongoid::Document

  field :name

  # ... other methods and such

  has_many :recipes
end

So the big problem is that calling object.user in the after_create method is nil, but it doesn’t even throw an exception, just results in nothing being returned, which I find the most bizarre, I’m not sure really on how to start debugging this.

It doesn’t look like you’re actually assigning a user to the recipe anywhere. Try:

def create
  @recipe = current_user.recipes.build(params[:recipe])
  @recipe.save

  respond_with @recipe, :notice => "You've created a recipe!"
end
