sqlite-net-擴展名-InsertWithChildrenAsync

Question

我正在嘗試使用“ sqlite-net-extensions”創建表。 但是問題總是返回錯誤。

返回的錯誤是“只讀”。

我創建了兩個模型來創建表。

型號->登錄

[PrimaryKey, AutoIncrement, Column("login_id")]
    [Indexed(Name = "LoginId", Order = 2, Unique = true)]
    public int Id { get; set; }

    [NotNull, Column("login_user")]
    [Indexed(Name = "LoginId", Order = 1, Unique = true)]
    public string UserName { get; set; }

    [NotNull, Column("login_password")] public string Password { get; set; }

    [OneToOne("login_id", "Login")]
    public User User { get; set; }

型號->用戶

[PrimaryKey, AutoIncrement, Column("user_id")]
    public int Id { get; set; }

    [NotNull, Column("user_name")]
    [Indexed(Name = "UserId", Order = 3, Unique = true)]
    public string Name { get; set; }

    [NotNull, Column("user_email")]
    [Indexed(Name = "UserId", Order = 2, Unique = true)]
    public string Email { get; set; }

    [ForeignKey(typeof(Login)), NotNull, Column("login_id")]
    [Indexed(Name = "UserId", Order = 1, Unique = true)]
    public int LoginId { get; set; }

    [OneToOne("login_id", "User", CascadeOperations = CascadeOperation.All, ReadOnly = false)]
    public Login Login { get; set; }

插入方式

public async Task InsertWithChildren(object o)
    {
        var connection = _sqliteWrapper.OpenDatabase();
        await connection.InsertWithChildrenAsync(o, recursive: true);
    }

Answer 1

繼續下一步

1.-創建一個SQLite連接。

2.-創建表格

3.-插入數據庫

 var connection = new SQLiteAsyncConnection(YourDBPath);
 connection.CreateTableAsync<Login>().Wait();
 connection.CreateTableAsync<User>().Wait();
 connection.InsertWithChildrenAsync(YourItem);
