lazy-loading

问题 I can't seem to get all elements on a webpage. No matter what I have tried using selenium. I am sure I am missing something. Here's my code. The url has at least 30 elements yet whenever I scrape only 6 elements return. What am I missing? import requests import webbrowser import time from bs4 import BeautifulSoup as bs from selenium import webdriver from selenium.webdriver.chrome.options import Options from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support

问题 I have an web application that uses NHibernate as ORM. I enable lazy loading for my classes but I want to load some classes without lazy in a special situation. Now is there any utility or built in class in NHibernate that force a class to load it without lazy in a special situation? Note: I don't want to remove lazy property in my mapping file, because I use lazy loading in some of time. 回答1: Yes.

问题 While trying to do some tests on lazy loading, to check if i'm understanding it well, i got totally confused. Here's the entities i'm using on my test: @Entity public class Family { @Id private int id; @OneToMany(mappedBy="family", fetch=FetchType.LAZY) private Set<Person> members; //getters & setters public String toString(){ String s=""; for(Person p:getMembers()){ s+=p.getFirstName(); } return s; } } @Entity public class Person implements Comparable<Person>{ @Id private int id; private

问题 One of our model object in our application has many fields configured to be eagerly fetched like so: @ManyToOne(fetch = FetchType.EAGER) @JoinColumn(name = "field") public Field getField() { return this.field; } However I sometime do not need these information, which slow down my queries for nothing. I cannot change the behaviour and use FetchType.LAZY instead as I've no idea what will be the impact on the whole application (legacy...). Is there a way to simply tell hibernate to fetch nothing

问题 I am creating web app with spring-mvc [Layers: Controller -> Service -> DAO -> Entities] and I faced a problem with lazy loading which makes me buffled. In general there is the following relationship. I have an Account [Entity] which can have many Words [Entity] and many Words may be assigned to many Accounts, so this is @ManyToMany. Account Entity @Entity @Table(name = "account") @Inheritance(strategy = InheritanceType.JOINED) public class Account { ... @ManyToMany(cascade=CascadeType.ALL,

问题 Following on from this question: NHibernate: Lazy loading of IUserType Seeing as I can't lazy load a property or a one-to-one relationship, is there a way I can use an IUserType with a many-to-one? Something like this (which doesn't work): <many-to-one name="Client" column="`ClientId`" lazy="true" type="EmployeeSystem.UserTypes.ClientUserType, EmployeeSystem" /> 回答1: Looks like NHibernate does not support custom loading ( IUserType ) for associations (many-to-one, one-to-one etc). As a side

问题 I'm implementing a payment gateway into my SPA built with angularjs. The problem is that this payment gateway requires you to include a script with a id of the payment. this is my current setup.... (note the controller just runs some server-side script, it returns all information about the payment I just need to get the id) Here is my controller: (function (){ var PaymentGateController = function ($scope, $rootScope, $state, paymentFactory, $sce) { $scope.ready = false; paymentFactory

问题 I'm getting data for my application through WCF service. And on the server side the service is using EF4.1 as a data access. Service method looks kind of like this : public List<JobOffer> GetAllJobOffers() { var allJobOffers = _jobOffersRepository.GetAll().ToList(); return allJobOffers; } And the repository is done this way public override IQueryable<JobOffer>GetAll() { return _context.JobOffers.Include(c => c.Company); } I am getting this strange error : An error occurred while receiving the

问题 I'm using the following code to lazy load an image into my UIImageView: [self.imv1 setImageWithURL:[NSURL URLWithString:myURL] placeholderImage:[UIImage imageNamed:@"loading.png"] completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) { // stuff here }]; When a user touches a button, I want the lazy loading of this to STOP completely, so that no image gets loaded and the download of the image stops. After I stop the lazy loading, I plan to load a different image into the same
