Question

我正在尝试在rails中运行create方法，以将项目插入数据库。我创建的代码如下：

def create
  @song = Song.create ( { :song => params[:song],
  :artist => params[:artist],
  :album => params[:album],
  :song_id => params[:song_id],
  :longitude => params[:longitude],
  :latitude => params[:latitude],
  :stream_url => params[:stream_url],
  :art_url => params[:art_url] } )

  respond_to do |format|
    if @song.save
      format.json { render :json => @song, :status => :created, :location => @song }
    else
      format.json { render :json => @song.errors, :status => :unprocessable_entity }
    end
  end
end

但是，我收到以下错误消息。我如何确保插入的内容是我想要的内容？

Answer 1

- ＆GT; Completed 201 Created

没有错误消息。记录已保存。

VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) ...values ->...

对于紧随其后的值，这些问号是占位符。这是正常行为。

每个问号按读取顺序替换为以下值。向右滚动可查看这些值。看起来一切都在那里。

这是一个安全问题。您是否在广告布局中添加了<%= csrf_meta_tags %>？

Rails数据库输入，值都是问号
