Question

我有一个控制器“Allan”和一个控制器“Marian” 他们都是平等的，在我创造“marian”之前，“allan”工作得很好。但现在，当我尝试创建一个新的Alla时，我明白了：

没有路线匹配{：action =＆gt;“show”，：controller =＆gt;“allans”} 尝试运行rake路线以获取有关可用路线的更多信息。

问题在于“玛丽安”完美运作。

有什么问题？

    @allans = Allan.where(day: @date)
    @total_allans   = Allan.count
    @current_allans = @allans.size
    respond_to do |format|

Answer 1

我真的不知道问题是什么，但我复制了Marias的代码并将名称“marias”更改为“allan”，并且它有效。所以也许是在没有注意的情况下我改变了。

没有路线匹配{：action =＆gt;“show”，：controller =＆gt;“allans”}
