運行:紅寶石1.9.3p0(2011-10-30修訂33570)x86_64的-darwin11.2.0]來說,Rails 3.2.0Elasticsearch,輪胎協會
我試圖讓彈性搜索通過工作TIRE寶石跨社團。
Daves-MacBook-Pro:outdoor dave$ rake environment tire:import CLASS=Gear FORCE=true
[IMPORT] Deleting index 'gears'
[IMPORT] Creating index 'gears' with mapping:
{"gear":{"properties":{}}}
[IMPORT] Starting import for the 'Gear' class
--------------------------------------------------------------------------------
101/101 | 100% rake aborted!######################################
undefined method `last_name' for nil:NilClass
Tasks: TOP => tire:import
這裏是我的模型: GEAR
class Gear < ActiveRecord::Base
attr_accessible :title, :size, :price, :image_url, :sub_category_id, :user_id
belongs_to :user
belongs_to :sub_category
validates :title, presence: true
validates :size, presence: true
validates :price, presence: true
validates :sub_category_id, presence: true
validates :user_id, presence: true
include Tire::Model::Search
include Tire::Model::Callbacks
def self.search(params)
tire.search(load: true, page: params[:page], per_page: 18) do
query { string params[:query]} if params[:query].present?
end
end
def to_indexed_json
to_json(methods: [:sub_category_name, :user_last_name, :user_first_name, :user_email])
end
def sub_category_name
sub_category.name
end
def user_first_name
user.first_name
end
def user_last_name
user.last_name
end
def user_email
user.email
end
end
用戶出於某種原因,在視圖上的輪胎進口進行耙或偶爾,當我不斷收到以下錯誤/錯誤
class User < ActiveRecord::Base
attr_accessible :first_name, :last_name, :email, :password, :password_confirmation
has_secure_password
has_many :gears
before_save :create_remember_token
email_regex = /\A[\w+\-.][email protected][a-z\d\-.]+\.[a-z]+\z/i
validates :first_name, presence: true,
length: {:maximum => 50 }
validates :last_name, presence: true,
length: {:maximum => 50 }
validates :email, presence: true,
format: {:with => email_regex},
uniqueness: {:case_sensitive => false}
validates :password, presence: true,
confirmation: true,
length: {within: 6..40}
def name
first_name + " " + last_name
end
private
def create_remember_token
self.remember_token = SecureRandom.urlsafe_base64
end
end
Sub_Category
class SubCategory < ActiveRecord::Base
attr_accessible :name
belongs_to :category
has_many :gears
end
我在想什麼?謝謝。
更新: 好吧,事實證明,我有我的數據庫中的幾個NIL值,這是錯誤的原因。希望這可以節省一些人一些時間。 – DaveG 2012-03-12 21:37:37
嗨,很好它是整理出來的 - 所以導入過程死了,當一些作者是'無'?...此外,也許你可以重複使用:https://github.com/karmi/railscasts-episodes/commit/ee1f6f39002f32ad25134c81dd6de74ff1b708fa爲索引關聯而不創建特殊方法... – karmi 2012-03-13 08:24:27
是的,導入過程不起作用,因爲我的一些關聯外鍵是零。它似乎不喜歡那樣。感謝您的建議,我會看看它。 – DaveG 2012-03-13 16:55:50
