레일 및 carrierwave 업로드 여러 이미지가 나는 제목, 내용하는 main_image로, 일부 기사를 쓸 수있는 형태가

Question

안녕하세요 실패, 그들은 모두이 같은 형태 진행 동일 모델 올 다른 모델의 다른 필드가 있습니다 progress_attachment 여러 이미지를 업로드하는 데 사용합니다. (나는 carrierwave 사용하고, exemple 등 SSR solution) 그것은 titledatecontentmain image 작동

!

하지만 여러 파일 업로드가있는 필드는 하나의 이미지를 허용합니다 ... 여러 번 받아 들여야합니다 ... 무엇이 잘못 되었나요?

= simple_form_for(@progress, html: { multipart: true}) do |f| 
    =f.input :title 
    =f.input :date 
    =f.input :content 
    =f.input :main_image 
    =f.simple_fields_for :progress_attachments do |f| 
    =f.input :image, multiple: true, name: "progress_attachments_attributes[:image][]" 
    =f.button :submit 

내 모델 :

progress.rb

class Progress < ActiveRecord::Base 
    default_scope ->{order(created_at: :DESC)} 
    mount_uploader :main_image, MainImageUploader 
    has_many :progress_attachments 
    accepts_nested_attributes_for :progress_attachments 

    validates :main_image, presence: true 
    validates :title, presence: true 
    validates :content, presence: true 
    validates :date, presence: true 
end 

progress_attachment.rb

class ProgressAttachment < ActiveRecord::Base 
    mount_uploader :image, ImageUploader 
    belongs_to :progress 
    validates :image, presence: true 
end

도움이 많이 덕분에 많이 주시면 감사하겠습니다!

Answer 1

내 다중 이미지가 작동합니다.

나는 대체 :

=f.input :image, multiple: true, name: "progress_attachments_attributes[:image][]"

=f.input_field :image, multiple: true, name: "progress_attachments_attributes[:image][]"
