RavenDB.Identity

The simple and easy Identity provider for RavenDB and ASP.NET Core. Use Raven to store your users and logins.

Instructions

Important: Upgrading from a previous version of RavenDB.Identity? See Updating From Old Version for steps to migrate to the latest RavenDB.Identity.

Add an AppUser class that derives from Raven.Identity.IdentityUser:

public class AppUser : Raven.Identity.IdentityUser
{
    /// <summary>
    /// A user's full name.
    /// </summary>
    public string FullName { get; set; }
}

In appsettings.json, configure your connection to Raven:

"RavenSettings": {
    "Urls": [
        "http://live-test.ravendb.net"
    ],
    "DatabaseName": "Raven.Identity.Sample",
    "CertFilePath": "",
    "CertPassword": ""
},

In Startup.cs, wire it all up:

public void ConfigureServices(IServiceCollection services)
{
    // Grab our RavenSettings object from appsettings.json.
    services.Configure<RavenSettings>(Configuration.GetSection("RavenSettings"));
    
    ...
    
    // Add RavenDB and identity.
    services
        .AddRavenDbDocStore() // Create an IDocumentStore singleton from the RavenSettings.
        .AddRavenDbAsyncSession() // Create a RavenDB IAsyncDocumentSession for each request. You're responsible for calling .SaveChanges after each request.
        .AddRavenDbIdentity<AppUser>(); // Use Raven to manage users and roles.
    
    ...
}

In your controller actions, call .SaveChangesAsync() when you're done making changes. Typically this is done via a RavenController base class for MVC/WebAPI projects or via an action filter. See our sample RavenSaveChangesAsyncFilter.cs.

Modifying RavenDB conventions

To modify RavenDB conventions, you can use the services.AddRavenDbDocStore(options) overload:

services.AddRavenDbDocStore(options =>
{
   options.BeforeInitializeDocStore = docStore => docStore.Conventions.IdentityPartsSeparator = "-";
})

Updating From Old Version of RavenDB.Identity

Using an old version of RavenDB.Identity and want to upgrade to the latest? You need to call the MigrateToV6 method:

// Update our existing users to the latest RavenDB.Identity v6.
// This is necessary only if you stored users with a previous version of RavenDB.Identity.
// Failure to call this method will result in existing users not being able to login.
// This method can take several minutes if you have thousands of users.
UserStore<AppUser>.MigrateToV6(docStore);

This upgrade step is necessary because we updated RavenDB.Identity to use RavenDB's cluster-safe compare/exchange to enforce user name/email uniqueness.

Previous versions of RavenDB.Identity had relied on IdentityUserByUserName IDs to enforce uniqueness, but this isn't guaranteed to work in a cluster. Calling MigrateToV6 will create compare/exchange values in Raven for each email address, and will remove the now-obsolete IdentityUserByUserNames collection.
