Hey, entityManager.save does insert or update. Is there a good way to find out what the entityManager did?

@reggi I looked into the github code. Found something like:

hasRelation<T>(target: ObjectType<T>|string, relation: string|string[]): boolean {
        const entityMetadata = this.connection.getMetadata(target);
        const relations = relation instanceof Array ? relation : [relation];
        return relations.every(relation => {
            return !!entityMetadata.findRelationWithPropertyPath(relation);
        });
    }

may this help you? :o

@reggi

@Lyth0 I tried using this.connection.getMetadata, for some reason it was taking for ever to run

Lyth0

@Lyth0

give me a second. I try to run it on my code

I got the response instantly :o

getConnection().getMetadata(Entity);

Thomas Reggi

@reggi

hmmmm

weird

I'll look into this thanks @Lyth0

Hi everyone, I'm new to TypeORM, after npm run typeorm migration:run there isn't any table created in the database while I've an entity in my project. can someone help me to solve this problem.

Thomas Reggi

@reggi

@carrowheap I've never migrated manually, once you set up the entities and make a connection the tables are created automatically.

Question: I am trying to query on deep relations, can this be done? https://stackoverflow.com/questions/56993963/query-by-deep-properties-on-relations

Thomas Reggi

@reggi

Trying to do this the legitimate way using .createQueryBuilder() and it's not returning the correct data, but the raw SQL is. Any ideas what I'm missing?

hey, what is the instance scope for a subscriber? Is it a singleton or per-request?

i.e can I safely store previous value as a member variable in beforeUpdate and then compare changes in afterInsert? Or will this suffer from concurrency issues?

I'm running into a databaseColumn type for User#email is not defined and cannot be guessed error when starting my server. I've seen typeorm/typeorm#2897, but I don't understand how the babel plugin is supposed to fix the issue.

If you define a join table and have two one-to-many relationships with it, can you also have a many-to-many?

https://typeorm.io/#/many-to-many-relations/many-to-many-relations-with-custom-properties

Looking at the example there, couldnt that be taken a step further to define a many to many using the defined/extended table?

Hi everyone, does having a composite primary key with a number and a many to one column work?

I've tried with

@ManyToOne(type => Invoice, invoice => invoice.lines, {
  primary: true
})
invoice: Invoice;

@PrimaryColumn()
@Column()
orderLineNum: number;

but it overwrites the primary key with the many to one primary key and then after the migration only one column is primary

Alessandro Tagliapietra

@alex88

seems that

  @ManyToOne(type => Invoice, invoice => invoice.lines, {
    primary: true
  })
  invoice: Invoice;

  @Column({
    primary: true
  })
  orderLineNum: number;

is the way to go

Hi, i go a problem with migrations, when one or more migration are already applied on the database, typeorm can't find the changes between the code and the live version of the database. That return me the message : "No changes in database schema were found - cannot generate a migration. To create a new empty migration use "typeorm migration:create" command"

I can generate the first migration without any problem. But i can't for the next migrations

If someone already know this bug / how to fix it. That can help me a lot. Thank's

@galkowskit

@remibruyere I know this won't be much help, but we gave up on TypeORMs migrations. My advice is (it saved us a lot of headaches): disable autosync and write migrations by hand (create empty migration via typeorm CLI). :(

Hi, I'm using this old sql.js v0.5.0 and don't understand how to change the conection in order to upgrade to 1.0

I'm using the Ionic implementation.

let dbOptions: ConnectionOptions;
 dbOptions = {
          type: 'sqljs',
          location: 'browser',
          autoSave: true
 };
 Object.assign(dbOptions, {
      synchronize: true,
      autoSchemaSync: true,
      migrationsRun: true,
      entities: [    tables   ]
    });
     return createConnection(dbOptions).then(connection => {
      console.log("Data Access connected!");
      return connection;
    }).catch(error => {
      //console.log("Data Access Error : ", );
      return null;
    });

Does this work in typeorm?

@Entity()
class Foo {
  @PrimaryGeneratedColumn() id: number
  nestedProp: {
    @Column() greeting: string
  }
}

Basically setting a nested property.

Hey, I'm trying out migrations:generate on an empty DB with postgres. For some reason the generated migration is doing the following:

Create the table as expected based on a single @Entity I have defined
Drop all the columns of the previously created table
Recreate all the columns that it just deleted

This seems buggy to me.

Sam Grönblom

@sgronblo

Seems like there are a lot of issues on GH related to migrations:generate

Is this channel kind of dead or?

Hi,

Can I use migrations with synchronized database is true?

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?

Sam Grönblom

@sgronblo

Aren't you describing a simple transaction?

Jorgen V

@jvik

Can I ask for help here, or is this channel for development of TypeORM?

Sam Grönblom

@sgronblo

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.
