My project is:

Base .NET Core Base directory plugin mode Multi-DbContext

Plus DbContext Code:

[DbConfigurationType(typeof(AdminDbConfiguration))]
    public class CTMSDbContext : AbpDbContext
    {
        public virtual IDbSet<Center> Centers { get; set; }

        public CTMSDbContext() : base("Default")
        {
        }

        public CTMSDbContext(string nameOrConnectionString)
            : base(nameOrConnectionString)
        {

        }

        public CTMSDbContext(DbConnection existingConnection)
            : base(existingConnection, true)
        {

        }

        public CTMSDbContext(DbConnection existingConnection, bool contextOwnsConnection)
            : base(existingConnection, contextOwnsConnection)
        {

        }
        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);

        }

    }
    public class CTMSDbConfiguration : DbConfiguration
    {
        public CTMSDbConfiguration()
        {
            SetProviderServices(
                "System.EntityFramework.SqlClient",
                System.Data.Entity.SqlServer.SqlProviderServices.Instance
            );
        }
    }

    [DependsOn(
        typeof(AbpZeroEntityFrameworkModule),
        typeof(AdminCoreModule),
        typeof(AdminEntityFrameworkModule),
        typeof(CTMSCoreModule))]
    public class CTMSDataModule : AbpModule
    {
        public override void PreInitialize()
        {
            Database.SetInitializer(new MigrateDatabaseToLatestVersion<CTMSDbContext, Configuration>());
            //Configuration.ReplaceService(typeof(IConnectionStringResolver), () =>
            //{
            //    IocManager.IocContainer.Register(
            //        Component.For<IConnectionStringResolver, IDbPerTenantConnectionStringResolver>()
            //            .ImplementedBy<DbPerTenantConnectionStringResolver>()
            //            .LifestyleTransient()
            //        );
            //});
            ////设置连接字符串名称
            //Configuration.DefaultNameOrConnectionString = "Default";
        }
        public override void Initialize()
        {
            IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());
        }
    }

    public class Configuration : DbMigrationsConfiguration<CTMSDbContext>
    {
        public Configuration()
        {
            ContextKey = "Magicodes.CTMS.CTMSDbContext";
            AutomaticMigrationsEnabled = true;
            AutomaticMigrationDataLossAllowed = true;
        }

        protected override void Seed(CTMSDbContext context)
        {

        }
    }

Problem: When I deploy it to server,the AdminDbContext(base AbpZeroDbContext<Tenant, Role, User>) access database is OK,But CTMSDbContext will can't connect to the database.Detail:

    Have you tried it? Fix a point,The CTMSDbContext works on these code on my local computer:

    public CTMSDbContext() : base(GetConnectionString())
            {
            }
            private static string GetConnectionString()
            {
                //Notice that; this logic only works on development time.
                //It is used to get connection string from appsettings.json in the Web project.
    
                var configuration = AppConfigurations.Get(
                    WebContentDirectoryFinder.CalculateContentRootFolder()
                    );
    
                return configuration.GetConnectionString(
                    AdminConsts.ConnectionStringName
                    );
            }
    

    I read the source,it should be not works on server. I tried a lot of ways, but it did not work. I think the default case is from "web.config" to get while .NET Core is appsettings.json.

    Hi,

    Can you return correct connectionString in this method to see if it works on server with correct connectionString ?

    private static string GetConnectionString()
    {
        return "CorrectConnectionStringHere....";
    }
    

    Then we can try to fix getting correct connection string problem for your second DbContext.

    Hi,

    Did it worked when you return connection string from GetConnectionString method ?

    Thanks.

    Hi,

    It is good. Can you send your both DbContext classes to <a href="mailto:info@aspnetzero.com">info@aspnetzero.com</a> ? We will take a look at it to fix your main problem.

    Thanks.
