Migrações automáticas para o ASP.NET SimpleMembershipProvider
Então eu tentei usar migrações automáticas com meu novo projeto MVC 4, mas de alguma forma não está funcionando. Euseguiu esta postagem no blog passo a passo.
Eu adicionei as alterações aoUserProfile
modelo de conta (oNotaryCode
campo):
[Table("UserProfile")]
public class UserProfile
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int UserId { get; set; }
public string UserName { get; set; }
public int NotaryCode { get; set; }
}
Então eu escrevi no console do gerenciador de pacotesenable-migrations
e uma classe Configuration apareceu (herda deDbMigrationsConfiguration<Web.Models.UsersContext>
então eu preencho a classe como:
public Configuration()
{
AutomaticMigrationsEnabled = true;
}
protected override void Seed(Atomic.Vesper.Cloud.Web.Models.UsersContext context)
{
WebSecurity.InitializeDatabaseConnection(
"DefaultConnection",
"UserProfile",
"UserId",
"UserName", autoCreateTables: true);
if (!Roles.RoleExists("Atomic"))
Roles.CreateRole("Atomic");
if (!Roles.RoleExists("Protocolista"))
Roles.CreateRole("Protocolista");
if (!Roles.RoleExists("Cliente"))
Roles.CreateRole("Cliente");
string adminUser = "randolf";
if (!WebSecurity.UserExists(adminUser))
WebSecurity.CreateUserAndAccount(
adminUser,
"12345",
new { NotaryCode = -1 });
if (!Roles.GetRolesForUser(adminUser).Contains("Atomic"))
Roles.AddUsersToRoles(new[] { adminUser }, new[] { "Atomic" });
}
E então eu tentei correrupdate-database -verbose
mas isso não funciona. Quer dizer, esta é a saída:
Já existe um objeto chamado 'UserProfile' no banco de dados.

**There is already an object named 'UserProfile' in the database.**
Eu sei que o objeto existe. Quer dizer, eu tento usar migrações automáticas para, precisamente, modificar e executar sem recriar manualmente o banco de dados. Mas de alguma forma isso não está funcionando.
Eu olho a documentação do MSDN e encontrei a propriedade:
AutomaticMigrationDataLossAllowed = true;
Mas defini-lo como verdadeiro não muda nada. Eu acho que estou perdendo alguma coisa, mas de alguma forma não encontra o que. Qualquer ideia?
