    hello guys
    I am facing a tough day due to FindConditions/FindManyOptions in Repository.find method.
    most of the worst, I've got this error :

    Hello. I can't seem to inject anything in an EventSubscriber. Whatever I try to inject, is undefined. What might be wrong?

    Can you specify the order of columns in a composite primary key?

    I think I am running into this bug: typeorm/typeorm#1668 which part of the code should I look at to see why the quotation is missing?
    Ey there! I have one question related with a best practice of adapting TypeORM to a microservice stack. I have several microservices developed in typescript, each one of them using typeGraphQL with different queries and mutation to different models. I'm wondering if there is a way to dynamically use TypeORM (i.e singleton pattern in an adapter common library) and define entities in a different place that the adapter is defined.
    So a new microservice added should ask for the entities it needs. I've taken a look to the custom repositories and separate entity definition, but I need some light on this.
    I've got 2 entities, Account and Item, after creating an Account, an Item needs to be created too. I'm thinking of doing this in AfterInsert, but if the Item creation fails, I want the Account to be deleted from the database, as if it were all in one transaction, anyone got any ideas?

    Aren't you describing a simple transaction?

    Can I ask for help here, or is this channel for development of TypeORM?
    Sam Grönblom
    You can try both, no guarantees either will work :)

    Hi guys. I am using Webpack in a project with TypeORM and I am having an issue with RepositoryNotFoundError. The connection is created by an internal code I should not change, so I was trying to use ormconfig.js to solve the issue. Do you have a suggestion of an approach to make that work automatically? I already separated the bundles in Webpack, each entity is transpiled to a separated js file.

    Hi all. Is there an official way to get the table prefix in a migration file?
    I have queries like "ALTER TABLE 'table_name'...", but I would like to load the table prefix from there.
    or the table name directly from the entity...

    Is it possible, using Repository, to select for update (table X), insert (table Y) ? Any example around
    hi, guys, is there a built-in mechanism to populate entity from Json like new User().fromJson(data)

    Is it possible to use @Query( type ---> using a ViewEntity????)
    I keep receiving an error GraphQL cannot determine the output type - Dunno if the ViewEntity works as Entity
    NVM --- I forgot the annotations :D my bad

    findAndCount and Count are supposed to work with MySQL? I'm receiving an error -> SELECT COUNT(DISTINCT()) FROM ....
    was this a dumb question or there are no active users to answer it? "hi, guys, is there a built-in mechanism to populate entity from Json like new User().fromJson(data)"

    Hi, any one knows why @BeforeUpdate() decorator/subscriber event dont work with mongodb? I cannot find code related to this in MongoQueryRunner, seems like its just calls methods from mongo driver without using Broadcaster or something like UpdateQueryBuilder does. I am trying to use repository methods replaceOne(), update(), when i use save() for new Entity @BeforeInsert() event is triggered, but update events are not. I know that mongodb is experimental, but is it okay or i am doing something wrong?)
    @dan-conachi as far as I know there no such method
    I'am inserting multiple related entities to a postgres db. In the logs I see multiple transaction being started even though I don't start a transaction myself.
    I assume that typeorm automatically starts transaction in certain cases so it can rollback however is this somewhere documented on what behvaiour I can expect?
    thank @warreee I found and use now on the entity static toClass(data: Object) { return plainToClass(Class, data, { excludeExtraneousValues: true }) }

    Hey, How can I add and remove specific elements from the array field in typeORM Postgres?

    Hi! I'm facing an issue with typeorm that I'm having trouble solving:

    I have a entity

    class MyEntity implements MyEntityInterface {
      @PrimaryColumn({ type: 'int' })
      public id: number;
      @Column({ type: 'varchar' })
      public message: string;

    now when I do a queryBuilder and a getMany(), I would like to have this new field in the result which is aggregated from other database tables


           // query builder for myEntity
            .addSelect(`EXISTS (
              SELECT true
              FROM other_table`, 'myAggregateField'

    how can I include the myAggregateField in the result?

    atm typeorm does some magic and cant build the MyEntity-object with the myAggregateField value in it
    I tried simply adding public myAggregateField?: boolean; to the MyEntity-class, but it didnt help

    Hi you all! What is the safer method to get the old values of my entity in my afterUpdate inside my Surbscriber class? thanks
