Rails：您如何访问RESTful帮助器？ [英] Rails: how do you access RESTful helpers?

问题描述

我正在尝试阅读本 Rails路由指南，但是我陷入了困境 3.3 部分：

I'm trying to work through this guide to Rails routing, but I got stuck in section 3.3:

创建RESTful路由还将在您的应用程序中提供一堆帮助程序

Creating a RESTful route will also make available a pile of helpers within your application

然后他们列出了一些帮助程序例如 photos_url ， photos_path 等。

and then they list some helpers like photos_url, photos_path, etc.

我的问题：

在哪里可以找到可用的助手的完整列表？

Where can I find the complete list of helpers that is "made available?"

是否有一个控制台中调用助手的方法？我创建了一个应用程序，然后使用 script / console 打开了控制台。我试图像这样在控制台上调用一个助手：

Is there a way to call the helpers in the console? I created an app, then opened up the console with script/console. I tried to call one of the helpers on the console like this:

>> entries_url

但是得到了：

NameError: undefined local variable or method `entries_url' for #<Object:0x349a4>

推荐答案

您其中有几个问题，其中大多数已经被以下人员回答。

You have several questions in there, most of which have already been answered by people below.

对一个尚未完全解决的问题的答案是：是的，您可以使用脚本/控制台以查看路线。只需输入 app。[route_helper] ，它将使用路径进行响应。例如， app.users_path 将返回 / users /

The answer to one that wasn't fully addressed however, is: yes you can use the script/console to see where your routes go. Just type in app.[route_helper] and it will respond with the path. For example app.users_path will return /users/

因此，在您的示例中，输入 app.entries_url 作为完整URL-或 app.entries_path 作为其相对路径控制台。

So for your example type app.entries_url for the full URL - or app.entries_path for its relative path within the console.
