铁路检查控制器中的要求类型?
原标题:Rails detecting the request type in the controller?

我有一个控制器,通过html显示用户概况,通过JSON显示用户的 h光。

class UsersController < ApplicationController

  def show
    @user = User.where(:id => params[:id]).first

    return redirect_to "/" if @user.nil?

    respond_to do |format|
      format.html { render :layout =>  application  }
      format.json { render :json => @user.to_json }
    end
  end
end

问题在于用户没有发现其通过超文本操作的转子,而是与JSON发生错误。 是否只有提出超文本要求,才有明确的办法? 什么是正确的铁路,如何处置?

问题回答

采用手稿形式核对,如果其不适用于所有格式。 或者,你会转而回去,为初等干事提供有意义的帮助。

如果不提供任何信息,说明请求失败的原因,似乎是一个问题,通过有意义地提供,而不是对所有形式进行转头处理,就更难以解决。

(你不需要具体说明申请的布局,实际上它造成了违约。)

针对评论的扩大(我想):

每个格式的区块只是:区块。 它们可能包含任意的法典,例如:

respond_to do |format|
  format.html { @user.nil? ? redirect_to "/" : render }
  format.json { render :json => @user.to_json }
end

也许不是最干净的,部分是因为我认为,首先处理它是错误的。
