    <p>I think it's more that <code>accessible_by</code> is probably a scope - which is Database/SQL-driven. Sphinx has its own query interface, and so ActiveRecord scopes don't apply.</p> <p>An inefficient workaround (gets all companies first):</p> <pre><code>company_ids = Company.accessible_by(current_ability).collect &amp;:id @companies = Company.search params[:search], :include =&gt; :order, :match_mode =&gt; :extended, :page =&gt; params[:page], :with =&gt; {:sphinx_internal_id =&gt; company_ids} </code></pre> <p>A couple of things to note: sphinx_internal_id is the indexed model's primary key - Sphinx has its own unique identifier named id, hence the distinction. Also: You don't want to call <code>paginate</code> on a search collection - Sphinx always paginates, so just pass the <code>:page</code> param through to the search call.</p> <p>There'd be two better workarounds that I can think of - either have a Sphinx equivalent of <code>accessible_by</code>, with the relevant information added to your indices as attributes - or, simpler if not quite as ideal, just get the company ids returned in the first line of my above snippet <em>without</em> loading up every company as an ActiveRecord object. Both will probably mean bypassing and/or duplicating Cancan's helpers.</p> <p>Although... maybe this would do the trick, taking the latter approach:</p> <pre><code>sql = Company.accessible_by(current_ability).select(:id).to_sql company_ids = Company.connection.select_values sql @companies = Company.search params[:search], :include =&gt; :order, :match_mode =&gt; :extended, :page =&gt; params[:page], :with =&gt; {:sphinx_internal_id =&gt; company_ids} </code></pre> <p>Avoids loading unnecessary Company objects, uses the Cancan helper (provided it is/returns a scope), and works neatly with what Sphinx/Thinking Sphinx expects. I've not used Cancan though, so this is a bit of guesswork.</p>

    1. COWow, slightly more complex than I'd hoped... Let me digest your approach - really appreciate you taking the time to answer

    2. COIt's also worth noting Ryan Bates (author of Cancan) has confirmed that accessible_by is a scope, so the final solution should do the trick. Any questions, let me know :)

    3. COIs there a way to pass sql directly to thinking_sphinx? This solution is awesome, but it seems like it would have trouble scaling, if the company_ids array got large.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
