    <p>I am writing a Angular app that should use either a freshly loaded JSON object via the sever (on page load), or in some cases, the app will need to request the same JSON object (on page load) from the server if the obj doesn't exist.</p> <p>Using a service/factory, how would one go about checking if the JSON obj exists on the page? If it does, the app would then use that data and inject it into the controller. If it doesn't exist, the app would reach out to the server and request it.</p> <p>For example:</p> <pre><code>var data = {item1: foo, item2: foo, item3: foo} </code></pre> <p>Let's say that exists on page load. Angular would then use the <code>data</code> var as the base to build the model. But if it doesn't, it would call the server, get the same obj and use that as its base.</p> <p>Although I'm fairly new to Angular, I've read/written enough to know how to make AJAX requests and properly bind the returned data. In this case, I guess I'm trying to find out what would be a proper way to check for data and figure out if it exists in order to determine if a call should be made when the app runs.</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.
