Carrierwave - 정의되지 않은 메소드`mount_uploaders '

Question

목표 => 여러 파일 업 로더가 작동 중입니다.

업 로더를 탑재하려고하면 다음 오류가 발생합니다. 내가 업 로더의 끝에있는 s을 제거하면

4.1.7@2.1.3 (Message)> mount_uploaders :attachments, AttachmentUploader 
NoMethodError: undefined method `mount_uploaders' for #<Class:0x007fc17b4cc658> 
from /Users/mm/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/activerecord-4.1.7/lib/active_record/dynamic_matchers.rb:26:in `method_missing' 

내가 얻을 :

4.1.7@2.1.3 (Message)> mount_uploader :attachments, AttachmentUploader 
=> :serializable_hash 

내가 클래스가 정확한지 확인해야합니다 생각이 기준으로합니다.

4.1.7@2.1.3 (Message)> AttachmentUploader 
=> AttachmentUploader < CarrierWave::Uploader::Base 

내 모델은 다음과 같습니다 :

class Message < ActiveRecord::Base 
    belongs_to :user 
    belongs_to :conversation 
    delegate :list, to: :conversation, allow_nil: true 
    mount_uploaders :attachments, AttachmentUploader 
end 

내 AttachmentUploader 클래스는 다음과 같습니다

class AttachmentUploader < CarrierWave::Uploader::Base 
    storage :file 
end 

내 messages 테이블은 데이터베이스에서 :

create_table "messages", force: true do |t| 
    t.integer "user_id" 
    t.integer "conversation_id" 
    t.datetime "created_at" 
    t.datetime "updated_at" 
    t.text  "payload" 
    t.hstore "headers",   default: {}, null: false 
    t.hstore "to",    default: [],    array: true 
    t.hstore "from",   default: {}, null: false 
    t.string "subject" 
    t.hstore "cc",    default: [],    array: true 
    t.text  "body" 
    t.text  "raw_body" 
    t.text  "raw_html" 
    t.json  "attachments" 
end 

이것은 내가 할 수있는 것입니다

어떤 도움 놀랄 것입니다! 나는 이것에 몇 시간 동안 붙어 있었다. :-)

고마워요!

Answer 1

보석에 그 방법이 존재하지 않았다는 것이 밝혀졌습니다.

나는 성공적으로 보석을 다시 설치했다. 그런 다음 수동으로 github 마스터 분기를 참조하고 다시 설치하여 작동했습니다.

Answer 2

here과 같이 수동으로 확장해야한다고 생각합니다. 해볼 수 있니?
