尝试在我的主页横幅中为我的rails应用程序创建图像
我已经设置了Dropbox API并将其连接到我的rails应用程序，当我运行它时它可以工作在本地主机上。图像显示正确。但是当我运行它时它符合正确要求，但是当我打开时，我收到应用程序错误

后.rb
class Post < ActiveRecord::Base
validates :company, :contact, :email, :telephone, :website, presence: true
belongs_to :posts
:storage => :dropbox,
:dropbox_credentials => Rails.root.join("config/dropbox.yml"),
end
在此文件中获取语法错误，因此删除了逗号，但仍会收到相同的错误
您是否尝试过使用 Paperclip 的 has_attached_file 属性（如 paperclip-dropbox gem 文档中所述）：
#app/models/post.rb
Class Post < ActiveRecord::Base
has_attached_file :avatar,
:storage => :dropbox,
:dropbox_credentials => Rails.root.join("config/dropbox.yml")
end
