小编Tom*_*Tom的帖子

我正在实现一个web api,它将使用实体框架6获取数据.我正在使用Sql Server 2014和visual studio 2015.While调试CustomerDao类中的代码我在customerOrderContext对象中看到一个异常,虽然我可以看到记录在客户对象中.然而,在使用块执行后,我无法看到任何记录.

((System.Data.SqlClient.SqlConnection)customerOrderContext.Database.Connection).ServerVersion

CustomerDao

using (var customerOrderContext = new Entities())
                {
                    return (from customer in customerOrderContext.Customers

                            select new CustomerOrder.BusinessObjects.Customers
                            {
                                Id = customer.Id,
                                FirstName = customer.FirstName,
                                LastName = customer.LastName,
                                Address = customer.Address,
                                City = customer.City,
                                Email = customer.Email,
                                Gender = customer.Gender,
                                State = customer.State,
                                Zip = customer.Zip
                            }).ToList();
                }

配置文件中的连接字符串如下所示

<add name="Entities" connectionString="metadata=res://*/EF.CustomerOrderContext.csdl|res://*/EF.CustomerOrderContext.ssdl|res://*/EF.CustomerOrderContext.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=Tom-PC\MSSQLSERVER2014;initial catalog=Ransang;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

上下文类如下

public partial class Entities : DbContext
{
    public Entities()
        : base("name=Entities")
    {
    }

    protected override …

我开发一个角度4应用程序,并在将数据绑定到表单时遇到问题.绑定代码似乎很好,不知道问题是什么.当我调试应用程序时,我可以看到结果正确填充了下面的代码行this.editMovieForm = result; 在setFormValues()方法中.当我检查控制台窗口时,我看到以下错误

我在 angular 4 中编写了一个指令，用于捕获 onFocus 和 onBlur。我可以看到我的指令在加载表单时被初始化，但是当我单击输入控件时没有看到 obBlur 或 Onfocus 触发。不知道出了什么问题。我在输入元素上设置了 ShortNumberFormatterDirective

指示

import { Directive, HostListener, ElementRef, OnInit } from "@angular/core"; 
//import { MyCurrencyPipe } from "./my-currency.pipe"; 


 @Directive({ selector: "[shortNumberFormatter]" }) 
 export class ShortNumberFormatterDirective implements OnInit { 


   private el: HTMLInputElement; 


   constructor( 
     private elementRef: ElementRef, 
    // private currencyPipe: MyCurrencyPipe 
   ) { 
     this.el = this.elementRef.nativeElement; 
   } 


   ngOnInit() { 
     //this.el.value = this.currencyPipe.transform(this.el.value); 
   } 


   @HostListener("focus", ["$event.target.value"]) 
   onFocus(value) { 
     //this.el.value = this.currencyPipe.parse(value); // opossite of transform 
   } 


   @HostListener("blur", ["$event.target.value"]) 
   onBlur(value) { 
     //this.el.value = this.currencyPipe.transform(value); …

我试图在我的角度应用程序中实现highcharts-angular(https://github.com/highcharts/highcharts-angular)并得到以下错误

Cannot read property 'chart' of undefined
at HighchartsChartComponent.updateOrCreateChart (highcharts-chart.component.ts:35)

我想使用bellcurve模块,但我无法使用它.

我试图使用stackblitz重新创建我的问题

请参阅https://stackblitz.com/edit/angular-unf7pz

不确定是什么问题

我已经在angular 7中实现了一个动态表。我正在显示列标题并垂直记录。如果您发现列标题已在组件中进行了硬编码。我目前正在渲染大约57列，我预见的问题是服务器中引入新列或列顺序更改时。当前的UI代码看起来与索引（即幻数）紧密相关。有没有更好的方法来处理UI呈现。

我有一个 Angular 8 应用程序并测试在 environment.ts 文件中设置的超时。我目前已将超时设置为 6 分钟。我有两个环境文件，即 environment.ts 和 enviornment.prod.ts。我相信执行 ng build --prod 时会使用 environment.prod.ts 。

运行 ng build 命令后，我无法在分发文件夹中找到环境文件。有人可以告诉我在哪里可以找到它吗？它是在某些二进制文件中吗？

这就是我的环境文件的样子

// The file contents for the current environment will overwrite these during build.
// The build system defaults to the dev environment which uses `environment.ts`, but if you do
// `ng build --env=prod` then `environment.prod.ts` will be used instead.
// The list of which env maps to which file can be found in `.angular-cli.json`.
