Question

我正在编写一个演示来练习＆＃34; carrierwave＆＃34;的宝石，它在开发ENV 中运行良好，但在部署到时失败了Heroku的

当我： heroku运行rails s 时，出现此错误：

/app/app/models/article.rb:9:in`' ;:未初始化的常量Article :: PictureUploader（NameError）

我的代码：应用程序/模型/ article.rb

  class Article < ActiveRecord::Base
    belongs_to :user
    has_many :comments, dependent: :destroy
    has_many :likes
    validates :title, presence: true, length: {maximum: 50}
    validates :content, length: {minimum: 10}
    self.per_page = 10
    attr_accessor :floor_number
    mount_uploader :picture, PictureUploader
    validate :picture_size

上传/ picture_uploader.rb

  class PictureUploader < CarrierWave::Uploader::Base

    include CarrierWave::MiniMagick

    process resize_to_limit: [600, 600]

    storage :qiniu

    def store_dir
      "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
    end

   def extension_white_list
     %w{jpg gif png jpeg}
   end
 end

分贝/ schema.rb

ActiveRecord::Schema.define(version: 20150529021048) do

  create_table "articles", force: :cascade do |t|
    t.string   "title"

    t.string   "label"
    t.integer  "user_id"
    t.datetime "created_at", null: false

  end

  add_index "articles", ["user_id"], name: "index_articles_on_user_id"

    t.integer  "article_id"

  add_index "messages", ["user_id"], name: "index_messages_on_user_id"

  create_table "users", force: :cascade do |t|
    t.string   "email",                  default: "", null: false
    t.string   "encrypted_password",     default: "", null: false
    t.string   "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"

  end

  add_index "users", ["email"], name: "index_users_on_email", unique: true
  add_index "users", ["reset_password_token"], name:  "index_users_on_reset_password_token", unique: true

end

Answer 1

您是否已将app/uploaders/提交给heroku master？

我有同样的错误，忘记将这些上传者文件添加到远程存储库
