The rest of the tests look good, just remove the one I mentioned or change it so it's mocking the sequelize functionality

[jmcdo29]

Just a few more changes I noticed

Why is this needed? (and how can we avoid making this change)

[Tony133]

I followed the directions in the documentation: https://docs.nestjs.com/techniques/database#models ,
by adding the models in SequelizeModule.forRoot({...})

[kamilmysliwiec]

This shouldn't be required when autoLoadModels is set to true

[Tony133]

I wouldn't want to be wrong, but in sequelize version 5, registering the model in SequelizeModule.forRoot ({...}) was an alternative to extending the Model class, like this example export class Post extends Model<Post> {.... }.

Now from version 6, under the hood of sequelize something seems to have changed, so as you said autoLoadModels: true automatically loads the Modules if set to true, similar to TypeORM, now I tried to remove models:[] and it seems to work.

Maybe we should update the documents for this, what do you think?

Then I wanted to ask you but is the models:[] setting still useful to use? maybe you could remove it as a setting?

Conflicts resolved in package.json👍

Conflicts resolved in package.json👍, however I have removed in a commit models: [] in SequelizeModule.forRoot({})
