I have an Ingredient which has a Measurement.
class Ingredient < ActiveRecord::Base
has_one :measurement
belongs_to :recipe
accepts_nested_attributes_for :measurement
end
class Measurement < ActiveRecord::Base
belongs_to :ingredient
end
The schemas appear right:
create_table "ingredients", :force => true do |t|
t.integer "measurement_id"
t.integer "recipe_id"
t.string "quantity"
t.string "food"
t.datetime "created_at"
t.datetime "updated_at"
end
create_table "measurements", :force => true do |t|
t.string "size"
t.float "quantity"
t.string "abbreviation"
t.string "measurement"
t.string "measurement_type"
t.string "equivalent"
t.datetime "created_at"
t.datetime "updated_at"
end
But I'm still getting this error preventing me from doing an
ingredient.measurement.abbreviation, but ingredient.measurement_id
works:
ActiveRecord::StatementInvalid in Recipes#show

where line #14 raised:
