是否有一种方法可以在过滤器前提供目标方法的名称 。
例如,我有以下代码
before_filter :login
def show
#...
end
def login
# ...
# get the name of method original called
# ...
end
http://<host>/show 调用, 后又调用登录
能给我一个 show 字符串或类似的字符串吗? 这样我就可以把指令传送到登录中, 实际发生在另一个控制器上, 以便返回到原始目标方法
您可以简单地从参数获取动作 : 参数[: action]
@apneadiving提到,您可以访问 params[:action] 获得“目标”(即“show”、“index”等)。
一个警告是,通常在_过滤器之前,您应该使用 request.params ,而不是仅仅使用 params ,因为有时仅仅使用 params 就会引起奇异的行为(我过去曾这样做过,我不记得确切的奇异行为,但并不理想)。此外,如果你更新参数,我发现我需要合并来请求。参数需要合并,而不是仅仅做诸如 params[:keys]=value 之类的事情。
