你尝试'<（％）=的link_to “编辑”，edit_post_path（post.id）：类=>“BTN BTN - 默认“％>'？ –

变化:post到post在卡部分

<%= link_to "Edit", edit_post_path(post), :class => "btn btn-default" %>

Rails正在发送:post为:id像{“身份证” =>“：后”}值

而且set_params试图与params[:id]发现它是“：后”

@post = Post.find(:post)

我确实尝试过。由于某种原因，它在控制器上出现错误，当我删除set_post动作进行编辑时，出现错误并让我进入编辑窗体，但是当我向窗体添加数据时，我再次收到sam错误。希望有道理 –

你试过改变它在你的卡片部分？ –

是的，我做到了这一点，无济于事。当我渲染部分时，是否存在index.html.erb问题？ –

我已经解决了这个问题与以下变化：

index.html.erb 没有变化
