Body
To create a function that returns a promise is easy: <pre><code>function test() { var defer = Q.defer(); // an example of an async call serverCall(function (request) { if (request.status === 200) { defer.resolve(request.responseText); } else { defer.reject(new Error("Status code was " + request.status)); } }); return defer.promise; } </code></pre> Now you could use it with the .then(). Here is an example of how could work your primeData function: <pre><code>function primeData(forceRefresh) { function success(data) { if (!initialized) { datacontext.lookups = data.results[0]; initialized = true; } else { datacontext.lookups = { teams: getLocal('Teams', 'id'), // other lookup values here }; } } var getLookupsPromise = getLookups(forceRefresh); // .then method returns a new promise. var successPromise = getLookupsPromise.then(success); // success is called when the getLookupsPromise promise is resolved // Now success promise will resove when succes code is resoved. // If success where assync and it returned an other promise this will resolve when the promise resolves. var modelInitializePromise = getLookupsPromise.then(function () { model.initialize(datacontext); }); var datasetOnePromise = modelInitializePromise.then(getDatasetOne); var datasetTwoPromise = modelInitializePromise.then(getDatasetTwo); var nonDependantPromise = getNonDependantDataset(); // Generate a promise that will resolve when all promises are resolved return q.all([getLookupsPromise, successPromise, modelInitializePromise, datasetOnePromise, datasetTwoPromise, nonDependantPromise]); } </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.
