小编Den*_*and的帖子

有谁知道如何更改以下命令的输出目录:

dotnet ef  migrations add Initial --context EsportshubApi.Models.ApplicationDbContext

??

我试图添加选项:

--content-root-path 'Migrations/Identity' 

但那没有做任何事情.还有一个--data-dir选项以及其他与目录相关的选项,但它们都不是迁移的输出.

我的问题是我有2个DbContexts所以我希望他们的迁移分开.

我在linux上使用dotnet core 1.1,当我想从我的常规dbContext中分离identityContext时,我遇到问题,每当我在startup.cs中运行以下行时 - > configure:

//... some other services
using (var serviceScope = app.ApplicationServices.GetRequiredService<IServiceScopeFactory>().CreateScope())
{
    serviceScope.ServiceProvider.GetService<ApplicationDbContext>().Database.Migrate();
    //running other database.migrations here + seeding data. But it is the line above that causes problems

因此,该行抛出异常:实体类型'IdentityUserLogin'需要定义主键

我根本不明白这一点,为什么我的工作是给IdentityUserLogin一个主键？它是一个第三方类,我甚至没有触及它.我有以下简单的设置:

namespace EsportshubApi.Models
{
    public class ApplicationDbContext :  IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
        {
        }

        public ApplicationDbContext()
        {

        }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);


        }
    }
}

和applicationUser:

namespace EsportshubApi.Models.Entities
{

    public class ApplicationUser : IdentityUser
    {
        public ApplicationUser() { }

        public …

我正在使用linux上的dotnet核心,我正在尝试使用连接字符串配置我的DbContext到mysql Server.

我的DbContext看起来像这样:

using Microsoft.EntityFrameworkCore;
using Models.Entities;

namespace Models {
    public class SomeContext : DbContext
    {
        //alot of dbSets...
        public DbSet<SomeEntity> SomeDbSet { get; set; }

        public EsportshubContext(DbContextOptions<SomeContext> options) : base(options) {

        }

        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) 
        {
            optionsBuilder.UseMysql //Cannot find this method
        }


        protected override void OnModelCreating(ModelBuilder modelBuilder) 
        {
            //using modelBuilder to map some relationships
        }
    }
}

我的依赖关系看起来像这样:

"dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.0",
      "type": "platform"
    },
    "Microsoft.AspNetCore.Diagnostics": "1.0.0",
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.1",
    "Microsoft.Extensions.Logging.Console": "1.0.0",
    "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0", …

我的dotnet核心应用程序中有以下依赖项:

 "dependencies": {
        "xunit": "2.2.0-beta2-build3300",
        "dotnet-test-xunit": "2.2.0-preview2-build1029",
        "Moq": "4.0.10827"
    },

无论我下载什么版本的Moq,它只是不受支持,它说:

Package Moq 4.0.10827 is not compatible with netcoreapp1.0 (.NETCoreApp,Version=v1.0). Package Moq 4.0.10827 supports:
      - net35 (.NETFramework,Version=v3.5)
      - net40 (.NETFramework,Version=v4.0)
      - sl4 (Silverlight,Version=v4.0)
    One or more packages are incompatible with .NETCoreApp,Version=v1.0.

但是我在这篇博文上看到:.NET Core上的Moq它是可能的,我在工作室代码中有nuget插件,所以它自动填充包,我写的时候找不到任何包moq.netcore可能我要求更多的查找方法如果这样的插件实际存在,不仅仅是一个答案,因为现在我无法看到nuget如果dotnet Core支持包,那么你们如何检查它是否有支持？你是否只在Nuget.org上寻找包裹？

谢谢

编辑:解决方案project.json:

{
    "version": "1.0.0-*",
    "testRunner": "xunit",
    "dependencies": {
        "xunit": "2.2.0-beta2-build3300",
        "dotnet-test-xunit": "2.2.0-preview2-build1029",
        "moq": "4.6.38-alpha"
    },
    "frameworks": {
        "netcoreapp1.0": {
            "dependencies": {
                "Microsoft.NETCore.App": {
                    "type": "platform", …

因此，正如标题所述，我想知道是否有可能用dotnet cli做相当于“ npm run”的动作？例如，此片段来自我的project.json：

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.1.0",
      "type": "platform"
    },
    "Microsoft.AspNetCore.Diagnostics": "1.1.0",
    "Microsoft.AspNetCore.Server.IISIntegration": "1.1.0",
    "Microsoft.AspNetCore.Server.Kestrel": "1.1.0",
    "Microsoft.Extensions.Logging.Console": "1.1.0",
    "Microsoft.Extensions.Configuration": "1.1.0",
    "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.1.0",
    "Microsoft.Extensions.Configuration.FileExtensions": "1.1.0",
    "Microsoft.Extensions.Configuration.Json": "1.1.0",
    "Microsoft.Extensions.Configuration.CommandLine": "1.1.0",
    "Microsoft.AspNetCore.Mvc":"1.1.0",
    "Microsoft.EntityFrameworkCore": "1.1.0",
    //"MySql.Data.Core": "7.0.4-ir-191",
    //"MySql.Data.EntityFrameworkCore": "7.0.4-ir-191",
    "SapientGuardian.EntityFrameworkCore.MySql": "7.1.14",
    "Microsoft.AspNetCore.Identity.EntityFrameworkCore": "1.0.0",
    "moq":  "4.6.38-alpha",
    "Microsoft.EntityFrameworkCore.Design": "1.1.0",
    "Microsoft.EntityFrameworkCore.SqlServer": "1.1.0",
    "Microsoft.EntityFrameworkCore.Relational": "1.1.0"

  },
  "scripts": {
        "migrate-identity": "dotnet ef database update --context 'ApplicationDbContext'"
},

迁移身份是我添加的自我身份，可以执行此脚本吗？

否则我想我只会在我的项目中有一个scripts文件夹，没什么大不了的，但仍然:)

我希望本地开发一些web组件,即使互操作性不是很好.所以我在我的ubuntu操作系统上的chrome:// flags标签下启用了google-chrome-stable版本50.0.2661.102的实验性网络平台功能...但我仍然只有不推荐使用(根据developer.mozilla文档的链接)方法:

document.registerElement( {...})

在Firefox中也一样.我知道如果我安装了聚合物,那么polyfill会修复它,但据我所知,聚合物api与W3C标准不是100%相同.有没有人设法使用最新标准在浏览器中本地试用Web组件？特别是这部分标准我想试试:

2.1.1 Creating an autonomous custom element

This section is non-normative.

For the purposes of illustrating how to create an autonomous custom element, let's define a custom element that encapsulates rendering a small icon for a country flag. Our goal is to be able to use it like so:

<flag-icon country="nl"></flag-icon>
To do this, we first declare a class for the custom element, extending HTMLElement:

class FlagIcon extends HTMLElement {
  constructor() {
    super();
    this._countryCode …

我只是在学习F#,所以我正在尝试一些事情(我知道可以使用XUnit或其他东西)

我有以下断言方法,并且想法是它应该采用预期的异常和它期望抛出此异常的函数,然后执行函数并在with测试内部如果抛出的异常与预期的异常相同.

let assertException (testName : string) (expected : 'a when 'a :> Exception) functionToBeTested =
    try
        functionToBeTested
        (false)
    with
    | :? Exception as someException when someException :? expected ->
            printTestResultInMiddle (sprintf "Test: %s PASSED: Raised expected exception %A" testName expected) true 
            (true)
    | _ ->
        printTestResultInMiddle (sprintf "Test: %s FAILED: expected exception %A" testName expected) false
        (false)

它给了我在Unexpected symbol '(' in pattern matching. Expected '->' or other token. 尝试调用print方法的行中的错误.我不应该把它try ... with当作一个对待

match ... with

??

还有一个问题,我可以轻松地做到这一点吗？
