Error: Uncaught (in promise): Error: FOREIGN KEY constraint failed

Issue type:

[x] question [ ] bug report [ ] feature request [ ] documentation issue

Database system/driver:

[ ] cordova [ ] mongodb [ ] mssql [ ] mysql / mariadb [ ] oracle [ ] postgres [ ] sqlite [x] sqljs [ ] websql

TypeORM version:

[ ] latest [ ] @next [x] 0.1.11 (or put your version here)

Steps to reproduce or a small repository showing the problem:

Inside an ionic application I create the connection and populate it with data. My models contains relations from Product going down to other models, this mean in Product model I set up relation with cascade insert/updates so I only need to hydrate products and save instead saving all models separately.

Connection setup:

if (isBrowser(this.platform)) {
    dbOptions = {
        type: 'sqljs',
        autoSave: true,
        location: 'products',
    } as SqljsConnectionOptions;
}

return createConnection(Object.assign(dbOptions, {
    entities: this.getModelsToLoad(),
    synchronize: true,
    logging: true,
}));

After I populate database everything works fine, and then after I reload page, i can see queries ran in console, because synchronize: true, i assume. Last query is:

executing query:  CREATE TABLE "temporary_product" ("identifier" integer NOT NULL PRIMARY KEY AUTOINCREMENT, "id" varchar NOT NULL, ....)
executing query:  INSERT INTO "temporary_product"("identifier", "id", ....) SELECT "identifier", "id", ... FROM "product"
executing query:  DROP TABLE "product"
executing query:  ROLLBACK

than I receive the error.

Could you guys help me on how to overcome this. My expected outcome would be that I can use same data after a page reload, since that’s happens a lot when developing in browser an ionic app. Foreign keys enabled are not allowing me to re-initialize database again from existent data.

Thanks in advance, David

@samisamsam https://github.com/samisamsam What database are you using? Are the queries similar to the original issue? If not please open a new issue and tag me.
