回形针宝石不上传图像

Question

在整个申请过程中，我在多个地方都有回形针。我正在尝试使用我的一种表格上传到附件（两张图片），但它没有提供任何有用的信息来说明为什么它没有成功上传。我正在使用回形针 4.2.2。

回形针日志如下：

我只看到了 BEGIN/ROLLBACK 尝试。

我的控制器代码：

@listing_information_form = ListingInformationForm.create(listing_information_form_params)
if @listing_information_form.save && @listing_information_form.cancel_loan == nil
  redirect_to business_embedded_signing_path(@user)
elsif @listing_information_form.save && @listing_information_form.cancel_loan == true
  redirect_to business_root_path
else
  flash[:warning] = 'Unsuccessful'
  redirect_to :back
end

private

def listing_information_form_params
  params.require(:listing_information_form).permit(:business_id, :terms_acceptance, :logo_url, :picture_url, :business_profile, :loan_id, :loan_name, :logo, :loan_image, :cancel_loan)
end 

我的模特：

has_attached_file :logo,
    :styles => { :original => "90x90" },
    :storage => :s3, 
    :url => ":s3_domain_url",
    :path => "account/:class/:railsid/:filename"
has_attached_file :loan_image,
    :styles => { :original => "310x202>" },
    :storage => :s3, 
    :url => ":s3_domain_url",
    :path => "account/class/:railsid/:filename"

谁能提供有关 Paperclip 提供的跟踪的一些信息？我正在将这些文件上传到 s3，并且在我的整个应用程序中的其他表单上没有任何问题。

来自问题的cmets...

如果您在重定向之前puts @listing_information_form.errors.to_yaml 会发生什么？

@Questifer 的回答：

to_yaml 向我展示了我应该看到的荒谬错误。它与cancel_loan 字段有关。非常感谢你帮我调试这个 - 你为我节省了很多时间和挫败感。

很高兴我能帮上忙！有时只是用puts 啄东西会很有效。

奖励：我的另一个建议是将save 的值缓存在这样的局部变量中，这样您就不会意外运行save 两次：

@listing_information_form = ListingInformationForm.create(listing_information_form_params)
success = @listing_information_form.save

if success && @listing_information_form.cancel_loan == nil
  redirect_to business_embedded_signing_path(@user)
elsif success && @listing_information_form.cancel_loan == true
  redirect_to business_root_path
else
  flash[:warning] = 'Unsuccessful'
  redirect_to :back
end
