lazy-loading

AngularJS and Webpack Integration

会有一股神秘感。 提交于 2019-12-03 06:37:56
I am looking for some help with using webpack for a large AngularJS application. We are using folder structure based on feature (each feature/page has a module and they have controllers, directives). I have successfully configured webpack to get it working with Grunt, which produces one single bundle. I want to create chunks as its going to be a large app, we would like to load modules (page/feature) artifacts asynchronously. I am going through some of the webpack example to use 'code splitting' using require([deps],fn ) syntax. However I couldn't get the chunks lazy-loaded. First of all, I

Why it's not a good idea to pass entities as Models in MVC?

问题 We're developing a pretty large application with MVC 2 RC2 and we've received some feedback on the way we're using the Entity Framework's Lazy Loading. We're just getting the entities in the controller and sending them as models to the Views, that is causing that the view code asks the Database for the navigation properties we are using in it. We have read about this and it appears is not a good design, but we were wondering why? Can you help us understand this design problem? Thanks! 回答1:

Lazy loaded list view in GTK#

梦想与她 提交于 2019-12-03 05:05:57
I'm looking to display a large dataset via a list view in GTK# and performance is an issue here. I'm currently using a TreeView backed with a ListStore, but adding all my data to the ListStore takes forever. Is there a list view widget of some sort in GTK that supports lazy loading of data? In Winforms, you can use the VirtualMode property of DataGridView to handle this, but I don't see anything of the sort for GTK. James Hurford There, as far as I am aware, no widget to do what you want in Gtk, however, you can do something similar, in the end result, to the VirtualMode property, in the

How to asynchronously load a google map in AngularJS?

南笙酒味 提交于 2019-12-03 04:44:25
Now that I have found a way to initialize Google Maps with the help of Andy Joslin in this SO initialize-google-map-in-angularjs , I am looking for a way to asynchronous load a Google Map Object. I found an example of how to do this in the phonecat project. Notice how the JS files are loaded in this example: index-async.html In my Jade Scripts partial that is loaded into my program I tried: script(src='js/lib/angular/angular.js') script(src='js/lib/script/script.min.js') script $script([ 'js/lib/angular/angular-resource.min.js', 'js/lib/jquery/jquery-1.7.2.min.js', 'http://maps.googleapis.com

UITableView Lazy Image Load, images appear after table STOPS scrolling

混江龙づ霸主 提交于 2019-12-03 03:20:20
I implemented lazy image load for my UITableView using NSUrlConnection. This is all working very nicely. When I open my table, I automatically get the images when I wait for a second (on 3G). However, when I scroll, the table loads the new cell's, starts the NSURLConnections, but when the image is finished loading (in code), they do not get put into the view until the table actually stops scrolling.. The Youtube application is able to load the images into the table WHILE scrolling, I'd like to do this as well, any hints / pointers? StijnSpijker I just found my answer thanks to the 'Related'

Lazy evaluation in Ruby

亡梦爱人 提交于 2019-12-03 02:02:20
问题 I have a situation for Ruby, where an object is possibly necessary to be created, but it is not sure. And as the creation of the object might be costly I am not too eager creating it. I think this is a clear case for lazy loading. How can I define an object which is not created only when someone sends a message to it? The object would be created in a block. Is there a way for simple lazy loading/initialisation in Ruby? Are these things supported by some gems, which provide different solutions

EF Code First Lazy loading Not Working

眉间皱痕 提交于 2019-12-03 01:18:42
I am using code first with EF6 but cannot seem to get lazy loading to work. Eager loading is working fine. I have the following classes: public class Merchant : User { ... public virtual ICollection<MerchantLocation> MerchantLocations { get; set; } } public class MerchantLocation : BaseEntity { ... public int MerchantId { get; set; } public virtual Merchant Merchant { get; set; } } public class User : BaseEntity { ... } public class BaseEntity { ... public int Id { get; set; } } I test my lazy loading of the locations via the following code (which fails): public void Test_Lazy_Loading() {

Angular 5 with Angular cli non-lazy loading modules in the router

試著忘記壹切 提交于 2019-12-03 00:35:21
Building an angular5 app. The app requires a few alternate layouts. My approach is to handle the high level routing in the main app module routing file. The said file will map routes to modules. The modules will be lazy loaded for the non-essential speed driven pages and not lazy loaded for the speed critical pages: app-layout-router.module.ts file: import {NgModule} from '@angular/core'; import {PreloadAllModules, RouterModule, Routes} from '@angular/router'; import {PublicLayoutModule} from '@modules/layouts/public/public-layout.module'; import {AuthenticatedLayoutModule} from '@modules
