ZenStack Release v2.2.0

New Features

1. Comparing fields from different models in mutation policies #1463

Previous versions of ZenStack had an unintuitive limitation that you can't compare fields from different models in policy rules. E.g., the following snippet was not valid:

model Post {
  ...
  org Organization @relation(...)
  orgId Int
  author User @relation(...)
  authorId Int

  @@allow('update', orgId == author.orgId) // orgId and author.orgId are from different models
}

This release partly resolved the limitation by supporting such comparisons in mutation rules ("create," "update," and "delete").

Cross-model field comparison is not natively supported by Prisma, so ZenStack has to read the data out of the database and check the rules in the JS runtime. When ZenStack identifies a policy rule that involves such a comparison, the entire rule will be evaluated "post-read". Although it's usually not a big deal for mutation operations, you should be aware of the performance impact. For best performance, put expressions involving cross-model comparison into separate policy rules (so that other rules are still evaluated during database queries).

Cross-model field comparison is still not supported in "read" rules for two reasons:

1. It's very easy to result in reading an unbounded number of rows, filtering and discarding most of them.
2. It should be noted that "read" rules cover not only find but also aggregations. If we can't do a filtered aggregation on the database side, we'll have to reimplement it in the ZenStack library.

Please provide feedback in our discord if it's important for you.

2. Added support for Prisma 5.14's new createManyAndReturn API #1461

The returned results are properly filtered by access policies.

3. Relation filtering now respects field-level policies #1454

Background: ZenStack's "read" policy rules control not only what data you can retrieve but also how filters work. For example, in the following schema and query:

model Post {
  ...
  deleted Boolean
  @@allow('read', !deleted)
}

db.user.findMany({ where: { posts: { some: { published: true } } } });

Post model's read rules will be injected into the where clause, like:

db.user.findMany({
  where: {
    posts: {
      some: {
        published: true,  // user-provided filter
        deleted: false  // ZenStack injected filter
    }
  }
});

In previous versions of ZenStack, such filter injection only respected model-level policies but not field-level ones. This release fixes this missing part. For fields involved in filters, if they have field-level "read" rules, those rules will also be combined into the final filter. The consequence is, for the above example, if the published field is not readable, the findMany will result in an empty array.

The injection also respects "override" field-level rules, meaning that even if the Post model is not readable, but you have a field-level "read" rule for the published field that overrides the model-level policy, the published field can be used in the filter.

ZenStack Release v2.1.0

New Features

• Permission Checker #242

  A check API is extended to each model in the enhanced PrismaClient for checking permissions without querying the database. See more details here.

• auth() is resolved from all loaded schema files #1388

  In the previous release, to use auth() in a ZModel file, you'll need to import the schema file that contains the User model definition (or the model definition marked with @@auth). This release relaxed that requirement: auth() is now resolvable as long as the schema file containing the auth model is reachable through any import. You don't have to explicitly import it from every model now.

ZenStack Release v2.0.0 🎉

Features

Make sure you read the full upgrade guide before upgrading!

1. Polymorphic Relations

You can now model a polymorphic inheritance hierarchy using the "delegated types" pattern. Read more details here.

2. Using auth() Inside @default Attribute

You can now use the auth() function call inside @default() attribute in ZModel. It's very handy for models that should always be connected to the current user during creation. By providing such a default value, you don't need to explicitly connect to the user anymore:

model Post {
  ...
  author User @relation(...)
  authorId String @default(auth().id)
}

const db = enhance(prisma, { user: getCurrentUser() });
const post = await db.post.create({ title: 'Post1' }); // no need to connect the `author` field

Special thanks to Augustin for making this feature happen!

3. Edge Runtime Support (Preview)

The @zenstackhq/runtime package is compatible with Vercel Edge Runtime and Cloudflare Workers. See here for more details.

4. Server Adapter for NestJS

An official adapter for using ZenStack with NestJS that plays well with its dependency injection. See here for more details.

5. Formating ZModel in Prisma Style

Yes, we heard your voices, and here it comes 😄. Please update the VSCode extension and JetBrains plugin to the latest version and enjoy.

You can toggle back to the old behavior in the extension settings (VSCode only).

This release also contains many DX improvements and fixes.
