Rails : 多文件上传错误，数组为空

Question

我有一个大问题，我的 rails 应用程序无法正确上传照片我每次都会收到此错误。

照片右边可以看无法上传云端url

我必须这样做，因为管理员而不是从网站本身添加图片

cars_controller.rb

def index
 @cars = Car.all()
end

def show
 @car = Car.friendly.find(params[:id])
 @photos = @car.photos
 end
end

photos_uploader.rb

 include Cloudinary::CarrierWave

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

 def extension_whitelist
  %w(jpg jpeg gif png)
 end

photo.rb

mount_uploaders :photos, PhotosUploader
belongs_to :car

car.rb

extend FriendlyId
friendly_id :title, use: :slugged

mount_uploader :photo, PhotoUploader

has_many :photos

你可以看到我的错误

Cloudinary Ruby gem 当前不支持

mount_uploaders。可以在此处跟踪问题 https://github.com/cloudinary/cloudinary_gem/issues/304.

有一个示例项目 (https://github.com/taragano/Cloudinary_multiple_uploads) 说明了一个临时解决方法。模型是相册和照片，其中相册与照片有 has_many 关系，照片与相册有 belongs_to 关系。

模型 (https://github.com/taragano/Cloudinary_multiple_uploads/tree/master/app/models) 应如下所示：

class Photo < ActiveRecord::Base
    belongs_to :album
    mount_uploader :image, ImageUploader
end

class Album < ActiveRecord::Base
    has_many :photos, dependent: :destroy
end

在控制器中 (https://github.com/taragano/Cloudinary_multiple_uploads/blob/master/app/controllers/albums_controller.rb)，您需要遍历每张照片并将其存储到它所属的相册中：

def store_photos
    photos = params[:album][:photos]
    photos.each{|photo| @album.photos.create(image: photo)} if photos
end
