C# 使用MySQL数据库的ASP.NET标识-如何在开始时添加管理员用户?
我已经完成了关于如何使用具有ASP.NET标识的MySQL数据库的教程/示例:C# 使用MySQL数据库的ASP.NET标识-如何在开始时添加管理员用户?,c#,mysql,asp.net,asp.net-mvc,asp.net-identity,C#,Mysql,Asp.net,Asp.net Mvc,Asp.net Identity,我已经完成了关于如何使用具有ASP.NET标识的MySQL数据库的教程/示例: 现在我想添加一个功能,它可以从角色Admin开始创建Admin用户。过去我使用SimpleMembership和本地“SQL Server数据库”,这非常简单,现在我尝试通过在“MySqlInitializer”中添加用户来实现这一点。下面是我正在努力实现的代码: MySqlInitializer namespace IdentityMySQLDemo { public class MySqlIni
现在我想添加一个功能,它可以从角色Admin开始创建Admin用户。过去我使用SimpleMembership和本地“SQL Server数据库”,这非常简单,现在我尝试通过在“MySqlInitializer”中添加用户来实现这一点。下面是我正在努力实现的代码:

string.Format(
"SELECT COUNT(*) FROM information_schema.tables WHERE table_schema = '{0}' AND table_name = '__MigrationHistory'",
"17817412_kontadb"));
// if MigrationHistory table is not there (which is the case first time we run) - create it
if (migrationHistoryTableExists.FirstOrDefault() == 0)

我不知道为什么它不想在应用程序启动时创建管理员用户,我试图将此代码移动到“配置”或“MySQLConfiguration”“在迁移文件夹中。我还试图先创建所有表,然后用它添加管理员用户,但仍然不起作用。请告诉我这段代码中的愚蠢错误在哪里?看起来可能缺少
上下文。SaveChanges()
或三个
你的种子方法有问题吗?如果问题是在NuGet package manager控制台中运行update database
命令时,如果没有调用context.SaveChanges()
,则不会更新数据库
你还需要打3次电话
- 创建角色后
- 创建用户之后
- 将用户分配给角色后
var rolesForUser = userManager.GetRoles(user.Id);
if (!rolesForUser.Contains(role.Name))
{
var result = userManager.AddToRole(user.Id, role.Name);
}
我把它改成:
var rolesForUser = userManager.GetRoles(user.Id);
if (!rolesForUser.Contains(role.Name))
{
userManager.AddToRole(user.Id, role.Name);
}
因此,删除var结果=
