I'm facing a problem with a lazy loaded list of books. Initialy I load 10 books. If user is scrolling down, I load the next 10 books.
Let's say the user is now on "page" 4. Then he clicks on the 35th book to get the details of it. After returning to the list, he just sees the first 10 books and has to redo all the lazy loadings.
Is there any "caching" or storing possibiblity to avoid this? Thanks a lot for any hints!
[UPDATE] thanks for your replys!
routes
.state('app.books.list',{
...
...
resolve: {
books : function(bookFactoryBook) {
return booksFactoryBook.getList({page : 1});
}
}
})
.state('app.books.details',{
// just loads detail
})
ctrl (controller as syntax)
function bookControllerList(_books, ....) {
vm = this;
vm.books = _books;
......
// lazy loader just appends new data on vm.books
// after loading was successful
/**
* init lazy loader
*
* @desc initialize lazy-loader for books
* @return {void}
* @private
*/
function _initLazyLoader() {
if(_isLazyLoadingEnabled() === false) {
return;
}
// config lazy loader
var mapper = {
data : 'books', // vm.books
isEnabled : 'lazyLoadingEnabled',
indicatorId : 'lazyLoadingIndicatorId',
onDataLoaded : _afterLazyLoading
};
if(booksFactoryLazyLoader.setup(vm, mapper) === false) {
// failed to initialize lazy loader - disable feature
vm.lazyLoadingEnabled = false;
} else {
vm.lazyLoadingEnabled = true;
}
}
/**
* after lazy loading
*
* @desc manages data manipulation after lazy loading
* @param books - {Array} - new loaded data to manipulate
* @return {void}
* @private
*/
function _afterLazyLoading(books) {
// user logged in?
if(authFactorySession.isAuthorized() === true) {
// try to flag favorites in received books
books = _addFavoriteFlags(books);
}
// append data to vm
vm.books = vm.books.concat(books);
}
}
Could it be an issue with the controller as syntax? Or how can I extend the lifetime of my scope / vm object?
If I change the order of the states, and connect them as parent / child (app.books.list and app.books.list.detail) it doesn't change anything.
thanks for any hints
