Any background context you want to provide?
Make sure you drop your database tables, then run migrations and seeds again, both for test and development environments

Hi @oyewoas. Nice work so far. But I'd like to suggest, can we take advantage of the model relationships to fetch more details? For example, here, can we also get the user details and also the request details related to the comment?

Please check using include in Sequelize queries.

[oyewoas]

why do you think we need extra details apart from the comment @darasimiolaifa

[darasimiolaifa]

Say for instance, currently, what you're going to send to the frontend is the userId of the person who made the comment. But the frontend needs more than that. It needs the firstName, and lastname of the person, because that is what will be displayed. So, rather than send the userId, and then discover later that you still need to make another round trip to the database to fetch the user details, you can do it in one full query sweep by using include.

[darasimiolaifa]

You forgot to 'un-comment' these lines before pushing. Merge conflicts lurking.

Very good job @oyewoas

• if i update, I should be able to get a response of the update, i only got a message.
• I tried to do some security checks and I realized that anybody could get all comments/single comment, update or delete. It would be better it if its only the user that created the comment to be able to update/delete/get
