ruby-on-rails - 使用 Paperclip 时 ActiveAdmin 不上传图像

Question

我已遵循所有指南和答案，一切都正确显示，但实际上传并没有发生 :(

在我的 ActiveAdmin 中:

form :html => { :enctype => "multipart/form-data" } do |f|
  f.inputs do
    f.input :name
    f.input :image, :multipart => true
  end
end

这是我的模型:

  has_attached_file :image, :styles => { :medium => "300x300>", :thumb => "100x100>" }, :path => ":rails_root/app/assets/images/article_images/:id/:style_:basename.:extension"

我也试过没有路径，没用。

这是我的迁移:

class AddAttachmentImageToArticle < ActiveRecord::Migration
  def self.up
    add_column :articles, :image_file_name, :string
    add_column :articles, :image_content_type, :string
    add_column :articles, :image_file_size, :integer
    add_column :articles, :image_updated_at, :datetime
  end

  def self.down
    remove_column :articles, :image_file_name
    remove_column :articles, :image_content_type
    remove_column :articles, :image_file_size
    remove_column :articles, :image_updated_at
  end
end

Answer 1

问题是该死的 attr_accessible 没有 :image
