Ruby on rails Rails 4-回形针-Dropbox生产问题

我正在使用、、和Dropbox在创建产品时上载和存储图像。在本地，在开发过程中，图像文件会很好地上传到数据库中，并且是可见的，但在生产过程中，图像应该进入Dropbox，表单不会通过，我在查看Heroku日志时会遇到Dropbox身份验证错误。我已经三次检查了我的Dropbox安全密钥是否正确。我已经看过了所有相关的问题，但我找不到任何有效的方法

以下是heroku的错误：

 DropboxAuthError (User is not authenticated.):

 @product = Product.new(product_params)
 @product.user = current_user

respond_to do |format|

    format.html { render :new }
    format.json { 
      render json: @product.errors,
       status: :unprocessable_entity
   }
   end
 end
end

 private

 def set_product
  @product = Product.find(params[:id])
 end


 def product_params
  params.require(:product).permit(:description, :name, :permalink, :price, :file,  :user_id)
 end

使用此方法时，不要忘记告诉Heroku有关费加罗宝石的重要步骤

 rake figaro:heroku

他为我做了这件事。查看，我没有看到该命令，但有一节专门介绍如何部署到Heroku。我遇到了一个类似的问题，最后不得不将环境从开发更改为生产

class Listing < ActiveRecord::Base
  if Rails.env.production?
    has_attached_file :image,
    :styles => { :medium => "200x", :thumb => "100x100>" }, :default_url => "default.jpg",
    :storage => :dropbox,
    :dropbox_credentials => Rails.root.join("config/dropbox.yml"),
:path => ":style/:id_:filename"
    validates_attachment_content_type :image, :content_type => %w(image/jpeg image/jpg image/png)
  else
    has_attached_file :image,
    :styles => { :medium => "200x", :thumb => "100x100>" }, :default_url => "default.jpg"
  end
end

我不知道为什么当指定开发而不是生产时它不起作用，但至少后者起作用。

我可能会晚些回答，但它可能会帮助别人

在Dropbox的开发者控制台中，更改

'Development user'

设置是有效的。 最初创建应用程序时，

“开发用户”

将是

“仅限您”

因此，单击“启用其他用户”按钮，允许更多用户访问该应用程序
