import Generator from './Generator.js'

export default class AssocMany extends Generator {
  async generate(name, num, key = null, attrs = {}, buildOptions = {}) {
    const models = await this.factoryGirl.createMany(
      name,
      num,
      attrs,
      buildOptions,
    )
    return key
      ? models.map(model => this.getAttribute(name, model, key))
      : models
  }
}
