In my Item model, I have async methods such as delete, rename, etc. Whenever one of these methods is being executed, I display a spinner on the views to indicate loading. Since there are multiple async methods in the Item model, I find myself repetitively including code like this in my controller:
function delete() {
isRequesting = true;
item.delete().then(function() {
isRequesting = false;
}
}
function rename() {
isRequesting = true;
item.rename().then(function() {
isRequesting = false;
}
}
These instances of isRequesting= clutter up my code and can also be easily forgotten. On the other hand, I have a singleton called fileNavigator with many async methods, for which I use events to manage requesting status:
fileNavigator.on(FileNavigatorEvents.REQUESTING, function (event, requesting) {
isRequesting = requesting;
});
This approach eliminates the need to manually handle isRequesting when working with the async methods of fileNavigator. My question is if there is a similar pattern that could be applied to non-singleton instances of Item?
