Using TypeORM and getting this error:
ValidationError: Using global EntityManager instance methods for context specific actions is disallowed.
If you need to work with the global instance's identity map, use `allowGlobalContext` configuration option or `fork()` instead
The code that it corresponds to is below:
import { MikroORM } from "@mikro-orm/core";
import { __prod__ } from "./constants";
import { Post } from "./entities/Post";
import mikroConfig from "./mikro-orm.config";
const main = async () => {
const orm = await MikroORM.init(mikroConfig);
const post = orm.em.create(Post, {
title: "my first post",
});
await orm.em.persistAndFlush(post);
await orm.em.nativeInsert(Post, { title: "my first post 2" });
};
main().catch((error) => {
console.error(error);
});
I am unsure where I need to use the .fork() method
I faced a similar issue today when I upgraded the mikrorm setup from v4 to v5. After doing some RnD, I found the following changes helped me solve the mentioned error.
MikroORM.init call, pass the following propertyallowGlobalContext: true
em to create database entry. Instead use the following codeconst post = orm.em.fork({}).create(Post, {
title: "my first post",
});
The above changes should help you fix the error.
I am also very new to MikroORM. so, I am not sure why this error appears. But my uneducated guess is, they are restricting access to any changes to the global EntityManager em instance.
After doing some digging I found this solution:
yarn install dotenv
create a .env file in the root of the project
In your .env file paste the following:
MIKRO_ORM_ALLOW_GLOBAL_CONTEXT = true
Problem solved!
