Question

请帮我弄清楚我在做错了什么！我使用s3_direct_upload将基本映像上传到Amazon S3，然后POST以创建记录。我可以在网络选项卡（firebug）中看到它正在POST。但是，我不确定为什么这些参数没有被添加到数据库中。

这就是我要回来的：

   Started POST "/choices" for 127.0.0.1 at 2013-10-02 17:36:10 -0700
   Processing by ChoicesController#create as */*
   Parameters: {"url"=>"https://mybucket.s3.amazonaws.com/uploads%2F1380760569802-bneiuk2ghf4-22e59d1c8959be731bc71e31f0a9d7c6%2Fslide0003_image002.jpg",        
   "filepath"=>"/uploads%2F1380760569802-bneiuk2ghf4-22e59d1c8959be731bc71e31f0a9d7c6%2Fslide0003_image002.jpg", 
   "filename"=>"slide0003_image002.jpg", 
   "filesize"=>"73930", 
   "filetype"=>"image/jpeg", 
   "unique_id"=>"bneiuk2ghf4", 
   "choice"=>{
      "image"=>"https://mybucket.s3.amazonaws.com/uploads%2F1380760569802-bneiuk2ghf4-22e59d1c8959be731bc71e31f0a9d7c6%2Fslide0003_image002.jpg"
    }
   }
   (0.3ms)  BEGIN
   (0.4ms)  ROLLBACK
  Rendered choices/create.js.erb (0.1ms)
  Completed 200 OK in 16ms (Views: 6.2ms | ActiveRecord: 0.6ms)

 # app/controllers/choice.rb
  def create
   @choice = Choice.create(choice_params)
  end

 def choice_params
   params.require(:choice).permit!
 end

然后我的表单（为简洁起见省略了一些HTML）：

#app/views/new.html.erb
   <%= s3_uploader_form callback_url: choices_url, callback_param: "choice[image]", id: "s3-uploader" do %>
      <%= file_field_tag :file, multiple: true %>
   <% end %>

任何帮助都会很棒！

Answer 1

来自＆＃39; ROLLBACK＆＃34;，看起来您没有保存记录。也许，某些验证没有得到满足。变化

@choice = Choice.create(choice_params)

到

@choice = Choice.create!(choice_params)

这样您就可以获得有关您的记录未被保存的原因的信息。

Rails - Params没有被添加到模型中？
