The content of this page has not been updated to Strapi v5 yet.

✋ Caution

To avoid performance issues, bulk operations are not allowed on relations.

createMany()

Creates multiple entries.

Syntax: createMany(parameters) => { count: number, ids: id[] }

Parameters

• MySQL will only return an array of one id containing the last inserted id, not the entire list.
• Prior to Strapi v4.9.0, createMany() only returns the count.
