ConnectionStrings EFコアのDbContext

Question

私は間違っていることを知らず、データベースプロジェクトをセットアップするのに非常に苦労し、connectionstring dbcontextに関連したエラーを続けます。

私はちょうど

問題は私のデータが間違った場所にあると思われると、私はそれを修正するかどうかはわからないところで私の他のdbcontextあるlocaldbに接続している1 applicationdbcontextを持っています。このコードは、私のモデルフォルダ、私はこのコードを持っているstartup.csで

public DbSet<Customer> Customers { get; set; } 
public DbSet<Job> Jobs { get; set; } 
public DbSet<Order> Orders { get; set; } 
public DbSet<Staff> Staff { get; set; } 
public DbSet<RequestType> RequestType { get; set; } 
public DbSet<CustomerJob> CustomerJobs { get; set; } 

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) 
{ 
    optionsBuilder.UseSqlServer("Server=(localdb)\\mssqllocaldb;Database=Customers;Trusted_Connection=True;"); 
} 

... services.AddDbContext（=> options.UseSqlServer（Configuration.GetConnectionString（ "DefaultConnectionを"）のオプション））です。 services.AddDbContext（options => options.UseSqlServer（Configuration.GetConnectionString（ "ProdConnection"）））;まだ私はこのコードを持っている私のAppSettings configに

..

"ConnectionStrings": { 
    "DefaultConnection": "Server=(localdb)\\mssqllocaldb;Database=BRSCRM;Trusted_Connection=True;MultipleActiveResultSets=true", 
    "ProdConnection": "Server=(localdb\\mssqllocaldb;Database=Customers;Trusted_Connection=True;MultipleActiveResults=true" 
}, 

私は設定が供給されていること、エラーが使用されていない取得私のプロジェクト、実際に制御のDI反転、その袋を実行します猫とその火の上に！

お客様のOnConfiguringメソッドでoptionsBuilder.UseSqlServer("...行を削除する必要があります。

次に、このようにDbContextクラスにコンストラクタを追加します。

public YourDbContext(DbContextOptions<YourDbContext> options) : base(options) 
{ 
} 

追加DbContextクラス..

public class CustomerContext : DbContext 
{ 
    public DbSet<Customer> Customers { get; set; } 
    public DbSet<Job> Jobs { get; set; } 
    public DbSet<Order> Orders { get; set; } 
    public DbSet<Staff> Staff { get; set; } 
    public DbSet<RequestType> RequestType { get; set; } 
    public DbSet<CustomerJob> CustomerJobs { get; set; } 
    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) 
    { 
     optionsBuilder.UseSqlServer("Server=(localdb)\\mssqllocaldb;Database=Customers;Trusted_Connection=True;"); 
    } 
    protected override void OnModelCreating(ModelBuilder modelBuilder) 
    { 
     //modelBuilder.Entity<CustomerJob>() 
     // .HasKey(c => new { c.JobId, c.CustomerId }); 
     //code to require a staff member be assigned.. 

     // modelBuilder.Entity<Staff>().Property(s => s.Name).IsRequired(); 
     // modelBuilder.Entity<Customer>().Property(c => c.AssignedStaff).IsRequired(); 
    } 


} 


public class CustomerJob 
{ 
    public int CustomerJobId { get; set; } 
    public int CustomerId { get; set; } 
    public DateTime RequestDate { get; set; } 
    public int JobId { get; set; } 
    public Job Job { get; set; } 
} 

public class Job 
{ 
    public int JobId { get; set; } 
    public int CustomerId { get; set; } 

    public string BusinessName { get; set; } 
    public string Name { get; set; } 
    public string JobDescription { get; set; } 
    public string ServiceType { get; set; } 
    public string GoogleLink { get; set; } 
    public string PoisLink { get; set; } 
    public bool EquisRendered { get; set; } 
    public bool NadirsRemoved { get; set; } 
    public string FolderLink { get; set; } 
    public string ReviewPosted { get; set; } 
    public string Ingestion { get; set; } 
    public string Moderated { get; set; } 
    public bool Delivered { get; set; } 
    public string CustomerReview { get; set; } 
    public string PublishedLink { get; set; } 
    public DateTime RequestDate { get; set; } 
    public DateTime LastModifiedDate { get; set; } 
    public DateTime ScheduleShootDate { get; set; } 
    public DateTime CompletionDate { get; set; } 
    public List<CustomerJob> CustomerJobs { get; set; } 
    public Staff AssignedStaff { get; set; } 
} 

public class Staff 
{ 
    public int StaffId { get; set; } 
    public string Name { get; set; } 
    public string Phone { get; set; } 
    public string EMail { get; set; } 
} 

public class Order 
{ 
    public int OrderID { get; set; } 
    public int CustomerID { get; set; } 
    public int Order_Detail_Id { get; set; } 
    public List<Job> Job { get; set; } 
} 

public class RequestType 
{ 
    public int ID { get; set; } 
    public string Description { get; set; } 
} 

}

Startup.csクラス..とにかく

public class Startup 
{ 
    public Startup(IConfiguration configuration) 
    { 
     Configuration = configuration; 
    } 

    public IConfiguration Configuration { get; } 

    // This method gets called by the runtime. Use this method to add services to the container. 
    public void ConfigureServices(IServiceCollection services) 
    { 
     services.AddDbContext<ApplicationDbContext>(options => 
      options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"))); 
     services.AddDbContext<CustomerContext>(); 

     services.AddIdentity<ApplicationUser, IdentityRole>() 
      .AddEntityFrameworkStores<ApplicationDbContext>() 
      .AddDefaultTokenProviders(); 

     // Add application services. 
     services.AddTransient<IEmailSender, EmailSender>(); 
     // Add Oauth Options 
     /* Third Party Login Authenticaton Options Google */ 
     services.AddAuthentication().AddGoogle(googleOptions => 
     { 
      googleOptions.ClientId = Configuration["Authentication:Google:ClientId"]; 
      googleOptions.ClientSecret = Configuration["Authentication:Google:ClientSecret"]; 
     }); 
     /* End Google Options */ 
     /* Begin Facebook Options */ 
     services.AddAuthentication().AddFacebook(facebookOptions => 
     { 
      facebookOptions.AppId = Configuration["Authentication:Facebook:AppId"]; 
      facebookOptions.AppSecret = Configuration["Authentication:Facebook:AppSecret"]; 
     }); 

     /* End Facebook Options */ 

     /* Begin Microsoft Options */ 
     services.AddAuthentication().AddMicrosoftAccount(microsoftOptions => 
     { 
      microsoftOptions.ClientId = Configuration["Authentication:Microsoft:ApplicationId"]; 
      microsoftOptions.ClientSecret = Configuration["Authentication:Microsoft:Password"]; 
     }); 

     /* End Microsoft Options */ 

     /* Twitter Options */ 
     services.AddAuthentication().AddTwitter(twitterOptions => 
     { 
      twitterOptions.ConsumerKey = Configuration["Authentication:Twitter:ConsumerKey"]; 
      twitterOptions.ConsumerSecret = Configuration["Authentication:Twitter:ConsumerSecret"]; 
     }); 
     /* End Twitter Options */ 
     /* Begin Identity Options Configuration */ 
     services.AddMvc(); 
     services.AddAuthorization(options => 
     { 
      options.AddPolicy("RequireAdminRole", policy => policy.RequireRole("Admin")); 
     }); 
    } 

その今働いて、私のミスは私が定義されていたことでした2つの別々の場所で接続し、私は例外を投げたと思います。
