    <pre><code>function store($http) { this.products = []; this.url = 'php/db.php'; this.fields = ['product_id', 'product_name', 'product_description', 'product_price']; this.products = this.getProducts($http); } store.prototype.getProducts = function ($http) { return $http.post(this.url, { "action": 'products', "fields": this.fields }) .success(function (data, status) { return data; }) .error(function (data, status) { return []; }); } </code></pre> <p>When you return <code>$http.post</code> you're returning the <code>promise</code> it creates, so <code>this.products</code> would contain the <code>$http</code> promise. When the call returns from the server the promise is resolved by the <code>success</code> or <code>error</code> functions returning data in those functions sets the variable <code>this.products</code> to what is returned.</p> <p>In this case <code>this.products = []</code> is getting replaced right away by the promise from <code>$http.</code> If you try to access that data in your application before the resolve happens you'll get back the promise it contains which could cause problems if you try and use it in other functions as if it contained the array you need. You can use <code>$q.when</code> to "wait" on the promise to resolve and then assign the returned data, so if you try to use <code>this.products</code> elsewhere before then it will still contain an empty array and thus code like <code>this.products.length</code> will still work instead of throwing an error. So you could do the following:</p> <pre><code>function store($http,$q) { this.products = []; this.url = 'php/db.php'; this.fields = ['product_id', 'product_name', 'product_description', 'product_price']; $q.when(this.getProducts($http)).then(function(data){ this.products = data; }); } </code></pre> <p>If you do decide to go this route, just take note that you'll need to inject <code>$q</code> into your service and then pass it on through your <code>new</code> operator during class creation. This would resolve any race situation you may have in your controller.</p> <p>Of course you could also use the <code>resolve</code> provided for the <code>.when</code> method of the <code>$routeProvider</code> to resolve and controller dependencies prior to the controller taking "control"</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
