What methods/mixins sequelize adds to the models when an association is made?

Question

While going through the sequelize docs, more specifically the documentations about associations, I see that the guide casually shows the reader methods such as setTasks()<

Answer 1

To get a listing of the added methods try:

    const model = %yourSequelizeModel%
    for (let assoc of Object.keys(model.associations)) {
      for (let accessor of Object.keys(model.associations[assoc].accessors)) {
        console.log(model.name + '.' + model.associations[assoc].accessors[accessor]+'()');
      }
    }

To adjust the association names use "as" option:

Model.hasOne(models.series_promotions, { as: 'seriesPromotions' });

which changed the association method name from:

series.getSeries_promotion()
series.setSeries_promotion()
series.createSeries_promotion()

to

series.getSeriesPromotions()
series.setSeriesPromotions()
series.createSeriesPromotions()

based on the snippet above.
