Rails在多个标记过滤器上充当taggle

问题描述

路线：
get'mainpage /：tag

我有一个模型Tasks，可以标记为gem上的taggable。 'to：'mainpage＃index'，如：：tag

现在，当你点击一个标签时，它会带你进入带有该标签的所有任务。 / p>

我想要做的就是当你在一个标签页上时，点击一个额外的标签可以进一步过滤结果，点击标签名。 / p>

例子

标签账单（主页/账单）显示：

电缆（标有：电视，信用卡。票据）

椅子（标有：信用卡，账单）

b
$ b

表（标有：家具，钞票，沙拉）

当我点击信用卡标签页，我希望它只显示那些既是一个票据标签和信用卡标签的任务。

我有点盲目的如何这样做。

感谢任何帮助或建议

解决方案

从第3.11节：

  get' mainpage / * tags到：'mainpage＃index'，如：：tag 
  

你有像 / mainpage / bills 和 / mainpage / bills / tv / furniture 的网址。 b
$ b

第一个URL会在 mainpage＃index 方法中加入 params [：tags] ==' '，而第二个会带有 params [：tags] =='bills / tv / furniture'。然后，您可以简单地在 / 上分隔 params [：tags] 。

请注意，出于seo的目的，您可能想要为URL提供一些术语，即标签在URL中总是按字母顺序排列。

I have a model, Tasks, that can be tagged with the acts as taggable on gem.

The route: get 'mainpage/:tag', to: 'mainpage#index', as: :tag

Right now, when you click on a tag, it brings you to all tasks with that tag.

What I'd like to do is make it so that once you're on a tag page, clicking an additional tag further filters the results with the clicked tag name.

Ex.

On page for tag bills (mainpage/bills) displays:

Cable (tagged with: tv, credit card. bills)

Chairs (tagged with: credit card, bills)

table (tagged with: furniture, bills, salad)

When I click on the 'credit card' tag while on the bills tag page, I'd like to have it display only those tasks which are both a bills tag AND and credit card tag.

I'm flying a bit blind as how to do this.

Thanks for any help or suggestions

解决方案

From http://guides.rubyonrails.org/routing.html section 3.11:

get 'mainpage/*tags, to: 'mainpage#index', as: :tag

Adding this route allows you to have URLs like /mainpage/bills and /mainpage/bills/tv/furniture.

The first URL would come into your mainpage#index method with params[:tags] == 'bills', while the second one would come in with params[:tags] == 'bills/tv/furniture'. You could then simply split params[:tags] on /.

Note, for seo purposes, you probably want to come up with some nomenclature for the URLs, i.e. the tags are always alphabetical in the URL or something like that.
