    <p>There are two ways I can GET a REST resource by ID:</p> <pre><code>GET /users/1 GET /users/1,2 </code></pre> <p>The first returns a single object like <code>{id:1,name:"John"}</code> while the second returns an array like <code>[{id:1,name:"John"},{id:2,name:"Jill"}]</code>.</p> <p>Please, no arguments about whether or not this is legit REST; just accept that a service has this and I need to work with it.</p> <p>angular's $resource actually intelligently handles it from the <em>request</em> side:</p> <pre><code>User.get({users:['1','2']}) </code></pre> <p>transforms into</p> <pre><code>GET /users/1,2 </code></pre> <p>But it doesn't handle the response well. It expects a single object. If I change the definition to <code>isArray:true</code>, then it fails on a single request <code>GET /users/1</code></p> <p>How do I get it to intelligently handle both? </p> <p>EDIT: I did some weird hacking to get it to work, but would prefer a native method:</p> <pre><code> factory('Resource',['$resource','_',function ($resource,_) { return function(url,params,methods){ var defaults = { getSingle: {method: 'get', isArray:false}, getMultiple: {method: 'get', isArray:true} }, resource = $resource(url,params,angular.extend(defaults,methods)), urlParams = {}; _.each(url.split(/\W/), function(param){ if (param &amp;&amp; (new RegExp("(^|[^\\\\]):" + param + "\\W").test(url))) { urlParams[param] = true; } }); // do not override if they did if (!(methods||{}).get) { resource.get = function (params,success,error) { // look for multiples var isMultiple = false; _.each(params,function (val,key) { if (key &amp;&amp; urlParams[key] &amp;&amp; angular.isArray(val)) { isMultiple = true; return(false); } }); return this[isMultiple?"getMultiple":"getSingle"](params,success,error); }; } return(resource); }; }]). </code></pre>

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.
