Ruby on rails 更新的ruby和rails给.new.update方法带来了错误

我最近更新了我的ruby版本和rails版本

ruby 1.9.3 to ruby 2.1.1
rails 3.2.6 to rails 4.0.0

然后安装以下新gems

 protected_attributes(1.0.3)
 turbolinks(2.5.3)

在运行代码时，我在创建和更新方法时遇到以下错误

获取的参数数错误（2对1）错误位于.new、.update方法。 例如

我从表格中发送以下参数

  Parameters: {"utf8"=>"✓", "authenticity_token"=>"4DosQk69bQzV9idZapxjseVPNedORytYtNYH4rUCeBk=", "gallery"=>{"title"=>"test title 10", "description"=>"this is the gallery desription", "user_id"=>"1", "images_attributes"=>{"0"=>{"title"=>"test image", "description"=>"", "image"=>#<ActionDispatch::Http::UploadedFile:0xb48788b8 @tempfile=#<Tempfile:/tmp/RackMultipart20160229-7649-3kw561>, @original_filename="564650_685411374823853_181629729_n.jpg", @content_type="image/jpeg", @headers="Content-Disposition: form-data; name=\"gallery[images_attributes][0][image]\"; filename=\"564650_685411374823853_181629729_n.jpg\"\r\nContent-Type: image/jpeg\r\n">, "user_id"=>"1"}}}, "commit"=>"Update", "locale"=>"en"}

试试这个：

def gallery_params
  params.require(:gallery).permit(:title, :user_id, :description, images_attributes: [:title, :description, :image, :user_id])
end

---

一旦尝试这样做，让我们看看问题是否存在于强参数中

def create
        @gallery = Gallery.new({"title"=>"test title 10", "description"=>"this is the gallery desription", "user_id"=>"1", "images_attributes"=>{"0"=>{"title"=>"test image", "description"=>"", "image"=>#<ActionDispatch::Http::UploadedFile:0xb48788b8 @tempfile=#<Tempfile:/tmp/RackMultipart20160229-7649-3kw561>, @original_filename="564650_685411374823853_181629729_n.jpg", @content_type="image/jpeg", @headers="Content-Disposition: form-data; name=\"gallery[images_attributes][0][image]\"; filename=\"564650_685411374823853_181629729_n.jpg\"\r\nContent-Type: image/jpeg\r\n">, "user_id"=>"1"}}})
        respond_to do |format|
         if @gallery.save
          format.html { redirect_to :back, :notice => t('notice.gallery_created') }
          format.json { render json: @gallery, status: :created, location: @gallery }
         else
          format.html { render action: "new" }
          format.json { render json: @gallery.errors, status: :unprocessable_entity }
         end
       end
    end

def创建
@gallery=gallery.new（{“title”=>“test title 10”，“description”=>“这是gallery描述”，“user\u id”=>“1”，“images\u attributes”=>{“0”=>{“title”=>“test image”，“description”=>，“image”=>，“user\u id”=>“1}}）
回应待办事项|格式|
如果@gallery.save
format.html{redirect_to:back，：notice=>t（'notice.gallery_created'）}
format.json{render json:@gallery，status:：created，location:@gallery}
其他的
format.html{呈现操作：“新建”}
format.json{render json:@gallery.errors，status:：unprocessable_entity}
结束
结束
结束

很抱歉，这没有帮助我检查gem文件中的rails版本以及您发送的参数？我给出了答案，因为在注释中写入内容太大了，可能是不兼容的gem-完整错误回溯可能会有帮助。此外，我还认为您最好至少更新到最新的4.0.x版本，而不是4.0.0（即使这样，您仍然会有未修补的安全性更改）oks将更新到最新的4.0版本，并再次检查，感谢您在第行和Gallery上方的提示。新建（：title=>“test title 10”，：description=>“这是Gallery描述”，：user_id=>“1”），仍然给出相同的结果

def gallery_params
  params.require(:gallery).permit(:title, :user_id, :description, images_attributes: [:title, :description, :image, :user_id])
end

def create
        @gallery = Gallery.new({"title"=>"test title 10", "description"=>"this is the gallery desription", "user_id"=>"1", "images_attributes"=>{"0"=>{"title"=>"test image", "description"=>"", "image"=>#<ActionDispatch::Http::UploadedFile:0xb48788b8 @tempfile=#<Tempfile:/tmp/RackMultipart20160229-7649-3kw561>, @original_filename="564650_685411374823853_181629729_n.jpg", @content_type="image/jpeg", @headers="Content-Disposition: form-data; name=\"gallery[images_attributes][0][image]\"; filename=\"564650_685411374823853_181629729_n.jpg\"\r\nContent-Type: image/jpeg\r\n">, "user_id"=>"1"}}})
        respond_to do |format|
         if @gallery.save
          format.html { redirect_to :back, :notice => t('notice.gallery_created') }
          format.json { render json: @gallery, status: :created, location: @gallery }
         else
          format.html { render action: "new" }
          format.json { render json: @gallery.errors, status: :unprocessable_entity }
         end
       end
    end
