    <p>I have a service that contains a generic call to $http that all ajax calls uses. Here I have "centralized" error handling where the status codes results in redirects. </p> <p>"FieldsSync" service:</p> <pre><code>return $http({ method: 'POST', url: url, data: $.extend(defaultPostData, postData) }).error(function(data, status) { switch (status) { case 401: // "Unauthorized". Not logged in. redirect.toLoginPage(); break; case 403: // "Forbidden". Role has changed. redirect.toLogoutPage(); break; } }); </code></pre> <p>When calling one of the service functions from the controller I always return the deferred object to be able to hook up more error callbacks to be able to handle errors that should result in some kind of feedback for the user.</p> <p>Controller:</p> <pre><code>fieldsSync.createField(newField).success(function(data) { ... }).error(function(data, status) { switch (status) { // &lt;--- DO NOT WANT case 401: case 403: return; // These errors are handled (=redirects) in the generic error callback and we don't want to show do anything while it redirects. } ... // "Individual" error handling. =Displaying messages and stuff }); </code></pre> <p>But because I don't want error messages popping up before the redirect occurs I have to exit the error callback if the status codes already have been handled.</p> <p>The question is: How do i get rid of the switch cases in my controllers? Is it possible to exit the chain of error callbacks when a specific error code has been handled? Or is it possible to work around this in a less ugly way? :)</p> <p>This is a reoccurring problem for me, and my mind seems stuck.</p> <p>I have checked the docs and cant find any pretty solution for this in either $http or $q.</p>

    2. COHaving feedback just popping up for a few milliseconds and then disappears because the redirection is occurring doesn't look very nice. I don't see a point of doing something other then a redirect on 401.

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.

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