我使用活动管理员,我需要上传图库很多图像.我该怎么做?
我的代码:
我的代码:
class Gallery < ActiveRecord::Base belongs_to :event has_many :images attr_accessible :name,:publish,:images,:image,:images_attributes accepts_nested_attributes_for :images,allow_destroy: true validates :name,presence: true end class Image < ActiveRecord::Base belongs_to :gallery attr_accessible :url has_attached_file :url,:styles => { :medium => "300x300>",:thumb => "100x100>" } end ActiveAdmin.register Gallery do form html: { multipart: true } do |f| f.inputs do f.input :name f.input :images,as: :file,input_html: { multiple: true} end f.buttons end end
我有这个错误:
Image(#70319146544460) expected,got ActionDispatch::Http::UploadedFile(#70319105893880)
解决方法
尝试这个:
ActiveAdmin.register Gallery do form multipart: true do |f| f.inputs do f.input :name f.has_many :images do |p| p.input :url end end f.actions end end
