blocks|key|2894019|text|在研究了一下meta_search之后，我找到了一个相当令人满意的解决方案。语法有点笨拙，但它可以解决这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2894020|index+do
++...
++column+"Sections"+do+%7Csite%7C
++link_to+"Sections+(#{site.sections.count})",+:controller+=>+"sections",+:action+=>+"index",+'q[site_id_eq]'+=>+"#{site.id}".html_safe
++end
end|code-block|syntax|javascript|2894021|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

I worked out a reasonably satisfactory solution after poking around in meta_search for a bit. Syntax is a bit clunky, but it does the trick.

<pre><code>index do
 ...
 column "Sections" do |site|
 link_to "Sections (#{site.sections.count})", :controller =&gt; "sections", :action =&gt; "index", 'q[site_id_eq]' =&gt; "#{site.id}".html_safe
 end
end
</code></pre>

blocks|key|2894047|text|正如jgshurts所指出的，诀窍在于识别q[site_id_eq]查询参数。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2894048|但是，如果你不喜欢笨重的语法，你也可以只使用path+helper：|2894049|link_to+"Sections+(#{site.sections.count})",+admin_sections_path('q[site_id_eq]'+=>+site.id)|code-block|syntax|javascript|2894050|UrlHelper#link_to+documentation显示了更多这样的示例。|2894051|entityMap|0|LINK|mutability|MUTABLE|url|http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to^0|L|D|0|0|0|0|V|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Z|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|10|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|11|8|@]|D|@$9|12|A|13|1|14]]|E|$]]|$1|O|3|-4|5|6|7|15|8|@]|D|@]|E|$]]]|P|$Q|$5|R|S|T|E|$U|V]]]]

As jgshurts pointed out, the trick is identifying that <code>q[site_id_eq]</code> query parameter.

However, if you don't like the clunky syntax, you can also just use a path helper:

<pre><code>link_to "Sections (#{site.sections.count})", admin_sections_path('q[site_id_eq]' =&gt; site.id)
</code></pre>

The <a href="http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to" rel="nofollow">UrlHelper#link_to documentation</a> shows additional examples of this.

blocks|key|3107853|text|我使用以下语法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3107854|link_to+"Section",+admin_sections_path(q:+{+site_id_eq:+site.id+})|code-block|syntax|javascript|3107855|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

I use this syntax:

<pre><code>link_to "Section", admin_sections_path(q: { site_id_eq: site.id })
</code></pre>

 <code>#auto_link(resource, content = display_name(resource)) ⇒ Object</code>
 
 Automatically links objects to their resource controllers. If the
 resource has not been registered, a string representation of the
 object is returned.
 
 The default content in the link is returned from
 <code>ActiveAdmin::ViewHelpers::DisplayHelper#display_name</code>
 
 You can pass in the content to display
 
 eg: <code>auto_link(@post, "My Link")</code>

In an ActiveAdmin page, I would like to include a link to a list of related resources. For example, given that a
<ul>
<li>Site <code>has_many</code> Sections and,</li>
<li>Section <code>belongs_to</code> a Site (in my ActiveRecord models),</li>
</ul>
I would like my Site's show page to include a link to Sections within the site, which would go to the Section index page, with the Site filter preset.
<h3>Note that</h3>
<ul>
<li>I do not want to use ActiveAdmin's <code>belongs_to</code> function;</li>
<li>I don't want nested resources for a number of reasons (depth of nesting &gt; 2, as well as usability concerns).</li>
</ul>
What I want is to generate a URL similar to the one ActiveAdmin generates if I first go to the Sections index page and then filter by Site.
The query parameter list generated by ActiveAdmin's filtering feature is pretty crazy; is there a helper method I could use to achieve this goal?
Thanks!

ActiveAdmin - generate link to index, with filter preset?

在ActiveAdmin页面中，我想包含一个指向相关资源列表的链接。例如，假设一个Site has_many Sections和，Sections belongs_to a Site (在我的ActiveRecord模型中)，我想我的网站的显示页面包括一个链接到网站内的部分，这将转到部分索引页，与网站过滤器预设。请注意...
