    Hello everyone. Someone have an code example of custom logger for NestJS? I'm trying, but only logs info and query: log: [ { emit: 'stdout', level: 'query' }, { emit: 'stdout', level: 'warn' }, { emit: 'stdout', level: 'error' }, { emit: 'stdout', level: 'info' }, ],

    Somebody? I figured out that I need to throw the Prisma error inside my catche blocks to active the log, but I'm currently throwing the Nest Exceptions.

    Hello everyone, I have recently started to look into Hasura, and as much as I love the idea of having less to deal with graphql, I really appreciate the schema + migrations devX from Prisma and I would like to keep it in a setup involving Hasura (core, not hasura cloud). In the end, I would like to use Prisma as the ORM in my custom handlers, and define my database schema with this rather than the console. Per their documentation, it's possible, but I would like to have feedbacks from anyone actually using such a combination for real before moving forward with this. Has anyone some thoughts about it ? Especially, I have some questions • Is it possible to the extend that I want it to be ? • Is it okay, not to use the Hasura API in custom actions ? I feel like I am moving on to something considered a "bad practice" • In the end, was your migration to Hasura worth it ? Many thanks for your help, and happy new year !

    Hey all! The docs make reference to Dependent writes and list Nested writes as the only technique to achieve this. I have a nested create within an 
    .update()
    that needs to use the updated list of 
    subscribers
    for example in the nested write to make a calculation. Is there any way to access the updated list of 
    subscribers
    including the 
    id
    of newly created subscribers for an update that hasn't finished executing yet?

    Hi, I am wondering how to implement filtering with self reference tables. Let’s say you have User model which has Many to many self relations like below.
    Copy code
    model User {
  id         Int       @id @default(autoincrement())
  name       String?
  children   FamilyRelation[] @relation("child")
  parents    FamilyRelation[] @relation("parent")
}

model FamilyRelation {
  child    User @relation("child", fields: [childId], references: [id])
  childId  Int
  parent   User @relation("parent", fields: [parentId], references: [id])
  parentId Int

  @@id([parentId, childId])
}
    Now I want to query users who has ancestors named “John”.
    Copy code
    user
id | name   | parent_user_id | child_user_id
1  | "John" | []             | [2, 4]
2  | "A"    | [1]            | []
3  | "B"    | [4]            | []
4  | "C"    | [1]            | [4]
5  | "D"    | []             | []

→ query result should be "A", "B", "C".

    Hi, I've got a question regarding the update operation. Is there a way to get the initial value of the row as an output from .update()? Or do I have to do a findFirst() to get that and then an update?

    hi! related to this page https://www.prisma.io/docs/guides/performance-and-optimization/connection-management/configure-pg-bouncer does this also apply with statement mode instead of transaction mode? as per the pgbouncer docs:
    Copy code
    Statement Mode: Most aggressive method. This is transaction pooling with a twist: Multi-statement transactions are disallowed. This is meant to enforce "autocommit" mode on the client, mostly targeted at PL/Proxy.
    Wondering if you can use any of the two with prisma

    Hi all! Is there a way to use a graphql external API as a source of some PRISMA reolvers? I would like to merged in a central prisma server a custom DB and an external API from where I extract more data.

    Trying to deploy a large-ish Prisma & apollo-server-express application (~50 Prisma models) to Heroku, and deploying the application itself works, however when I try to run separate 
    ts-node
    processes for cron jobs or seeding the database, the app crashes apparently running out of memory:
    Copy code

    I bumped up our Heroku dyno from 512MB of RAM to a Standard 2X with 1GB for $50/month, but still crashes. To get more RAM, I'd have to go with a Performance M dyno for $250/month, which is not affordable especially given I'll need three environments (test, staging, and production). Wondering if anyone else has run into this problem?

    I'm thinking it might be the TypeScript compile step that's running out of memory when trying to run 
    ts-node
    since when deploying the server application that's working, TS gets compiled during the build step and the start command called by Heroku is just running 
    node
    not 
    ts-node
    .

    Hi, The way to add join records to a many to many is like this...
    Copy code
    await prisma.role.update({
    where: { id: 1 },
    data: {
      users: {
        create: [
            { user: { connect: { id: 1 } } },
            { user: { connect: { id: 2 } } },
            { user: { connect: { id: 3 } } },
        ]
      }
    }
  })
    How would I remove records from a many to many? I can do it like this...
    Copy code
    await prisma.role.update({
      where: { id: 1 },
      data: {
        users: {
          deleteMany: [
           { user_id: 1 },
           { user_id: 2 },
           { user_id: 3 },
         ]
        }
      }
    })
    But is there a similar way of doing it like the first example just with 
    disconnect
    ?

    Hi all - is there a way to create 4 entities in a nested write and connect them into a circular structure? e.g. A <- B is one-to-many A <- C is one-to-many B <-> C is many-to-many (with a join record)

    In one transaction, I'd like to Create one A Create one B, attached to A Create one C, attached to A Create one Join Record, connecting B and C

    Hi all, has anyone tried enabling WAL on SQLite ? From what I have experienced if two separate process try to use the same SQLite with Prisma, they go through the lock hell. WAL seems to be solving that for SQLite with journal files. However, I am struggling to find a way to enable that with Prisma

    Hi team 👋 Does anyone know if the prisma client has some method to test if the current schema is valid? I'm using ECS to host my backend and the pipeline does 
    primsa migrate deploy
    after the rollout of the pods. Before allowing users to consume the new pods of the API, ECS checks if these are healthy, in order to do that I usually define a simple endpoint at 
    /api/health_check
    that returns 200 OK. Now, ideally the new pods shouldn't be considered "healthy" until their prisma client matches the deployed DB schema, is there a way to "health test" prisma inside my health check endpoint?
