Migrating MySQL and Mongo on the same project crush

[khlilturki97]

I followed this tutorial and everything worked fine. I managed to work with relations on MySQL db.

In my use case, i had to add another datasource based on Mongo and i had a bug while migrating

Unable to migrate models not associated with this data source

i had to translate it from french, the original text is

Impossible de migrer les modèles non associés à cette source de données

i digged a little in RepositoryMixin class, and found out that the problem came from migrateSchema method

i overrided the method (copy past x) ) and changed

for (const b of dsBindings) {
  const ds = await this.get(b.key);
  if (operation in ds && typeof ds[operation] === 'function') {
    debug('Migrating dataSource %s', b.key);
    await ds[operation](options.models);
  }
  else {
    debug('Skipping migration of dataSource %s', b.key);
  }
}

to

for (const b of dsBindings) {
      const ds = await this.get(b.key);
      // console.log(ds);
      // @ts-ignore
      if (operation in ds && typeof ds[operation] === 'function') {
        console.log('Migrating dataSource %s', b.key);
        // @ts-ignore
        if (!options?.models || options?.models.length === 0) {
          // @ts-ignore
          await ds[operation](options.models);
        } else {
          const models = [];
          for (const model of options?.models) {
            // @ts-ignore
            if (Object.keys(ds.definitions).includes(model)) {
              models.push(model);
            }
          }
          // @ts-ignore
          await ds[operation](models);
        }
      } else {
        // debug('Skipping migration of dataSource %s', b.key);
      }
    }

i hope this bug will be fixed soon
