为Rails路线添加标题

本文介绍了为Rails路线添加标题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有如下所示的List对象：

I have List objects which are shown like this:

www.mysite/lists/123

www.mysite/lists/123

其中123是列表的ID。我想做的是在URL列表中添加标题，以便它提供更多信息（适用于google或其他工具）。所以我希望它看起来像这样：

Where 123 is the id of the list. What I would like to do is add the title of the list the url so it it more informative(for google or whatever). So I would like it to look like:

www.mysite/lists/123/title-of-list-number-123

www.mysite/lists/123/title-of-list-number-123

如何添加到这样的网址？如果您仅输入： www.mysite/lists/123没有标题，是否应该找到标题然后重定向到新路线？

How do you go about adding to a url like this? If you just enter: www.mysite/lists/123 w/o the title, should it find the title and then redirect to a new route?

推荐答案

如果您希望按ID保持查找呼叫不变，则可以执行与mplacona建议相反的操作：

If you want to keep your find-calls as they are (by id), you could do the opposite of what mplacona suggested:

def to_param "#{id}-#{title.parameterize}" end

使用此方法，您的find（params [：id]）将起作用，因为它将字符串转换为整数（仅当数字位于字符串的开头）。因此，这实际上是可行的：

With this, your find(params[:id]) will work because it'll convert the string to an integer (can only succeed if the number is in the beginning of the string). So this is will actually work:

List.find("123-my-title")

，并且将与

List.find(123)

参数化将自动将字符串转换为漂亮 URL。在此处了解更多信息： api.rubyonrails/ classes / ActiveSupport / CoreExtensions / String / Inflections.html＃M001367

The parameterize will automatically convert the string to a "pretty" url. Read more here: api.rubyonrails/classes/ActiveSupport/CoreExtensions/String/Inflections.html#M001367

如果您想要更多功能，我建议 friendly_id 。

If you want a bit more functionality, I'll suggest friendly_id aswell.
