Database system/driver:

[ ] cordova [ ] mongodb [ ] mssql [ ] mysql / mariadb [ ] oracle [ ] postgres [x] sqlite [ ] sqljs [ ] react-native [ ] expo

Steps to reproduce or a small repository showing the problem:

First, this is my entity.

User.ts

import { Entity, Generated, Column, OneToMany, CreateDateColumn, UpdateDateColumn } from 'typeorm'
import Mutation from './Mutation'

@Entity('user')
export class User {
  @Column({
    unique: true,
    primary: true
  })
  @Generated('uuid')
  id: string

  @Column()
  name: string

  @Column({
    nullable: true
  })
  class: string

  @Column({
    nullable: true
  })
  nik: string

  @Column({
    nullable: true
  })
  address: string

  @Column({
    default: false
  })
  isDeleted: boolean

  @Column({
    default: 0
  })
  balance: number

  @OneToMany(type => Mutation, mutation => mutation.user)
  mutations: Mutation[]

  @CreateDateColumn()
  createDate: string

  @UpdateDateColumn()
  updateDate: string
}

export default User

Mutation.ts

import { Entity, Generated, Column, ManyToOne, CreateDateColumn, UpdateDateColumn } from 'typeorm'
import User from './User'

@Entity('mutation')
export class Mutation {
  @Column({
    unique: true,
    primary: true
  })
  @Generated('uuid')
  id: string

  @Column({
    enum: ['ADD', 'SUBSTRACT']
  })
  type: string

  @Column()
  balance: number

  @ManyToOne(type => User, user => user.mutations)
  user: User

  @CreateDateColumn()
  createDate: string

  @UpdateDateColumn()
  updateDate: string
}

export default Mutation

ormconfig.js

module.exports = {
  type: 'sqlite',
  database: dbPath,
  autoSchemaSync: true,
  synchronize: true, /* I think this is cause the problem */
  autoSave: true,
  logging: true,
  entities: ['./app/database/entity/*.js']
}

So everything works fine. Insert new user, CRUD user, CRUD mutation. But after close my app, and reopen my app, everything looks error.

On the console I see

query: BEGIN TRANSACTION
query: SELECT * FROM "sqlite_master" WHERE "type" = 'table' AND "name" IN ('mutation', 'user')
query: SELECT * FROM "sqlite_master" WHERE "type" = 'index' AND "tbl_name" IN ('mutation', 'user')
query: PRAGMA table_info("user")
query: PRAGMA index_list("user")
query: PRAGMA foreign_key_list("user")
query: PRAGMA table_info("mutation")
query: PRAGMA index_list("mutation")
query: PRAGMA foreign_key_list("mutation")

query: INSERT INTO "temporary_mutation"("id", "type", "balance", "createDate", "updateDate", "userId") SELECT "id", "type", "balance", "createDate", "updateDate", "userId" FROM "mutation"
query: DROP TABLE "mutation"
query: ALTER TABLE "temporary_mutation" RENAME TO "mutation"
query: CREATE TABLE "temporary_user" ("id" varchar PRIMARY KEY NOT NULL, "name" varchar NOT NULL, "class" varchar, "nik" varchar, "address" varchar, "isDeleted" boolean NOT NULL DEFAULT (0), "balance" integer NOT NULL DEFAULT (0), "createDate" datetime NOT NULL DEFAULT (datetime('now')), "updateDate" datetime NOT NULL DEFAULT (datetime('now')))
query: INSERT INTO "temporary_user"("id", "name", "class", "nik", "address", "isDeleted", "balance", "createDate", "updateDate") SELECT "id", "name", "class", "nik", "address", "isDeleted", "balance", "createDate", "updateDate" FROM "user"
query: DROP TABLE "user"
query failed: DROP TABLE "user"
error: { Error: SQLITE_CONSTRAINT: FOREIGN KEY constraint failed errno: 19, code: 'SQLITE_CONSTRAINT' }
query: ROLLBACK
Cannot make connection

Actually I can solve the error by drop all the data in mutation table, but I don’t want to always delete all my data when I need to run the app.

After googling I found this https://github.com/typeorm/typeorm/issues/1530#issuecomment-361850741 I think that’s look legit , but I’m not sure how to fix correctly.

I’ve tried typeorm@next and @latest Any answer will be help

Disabling foreign constraints during the sync process with sqlite should fix it.

it works for me ( v 0.2.16) by setting false to sync in ConnectionOptions and use the following function to sync :

  async fixedSync(connection: Connection) {
     await connection.query('PRAGMA foreign_keys=OFF');
     await connection.synchronize();
     await connection.query('PRAGMA foreign_keys=ON');
  }
