Model.update() set null on values which are not given

For me this is a bug. Let’s say I have a table ‘users’ with 4 columns: ‘firstName’, ‘lastName’, ‘createdAt’, ‘updatedAt’. I do:

User.update({ firstName: 'Jane' }, { where: { id: 1 } })

The SQL query looks like this:

UPDATE "users" SET "first_name"="Jane","last_name"=NULL,"created_at"=NULL,"updated_at"=NULL WHERE "id" = '1'

Why other values are set to NULL ? I think the correct update should look like this:

UPDATE "users" SET "first_name"="Jane" WHERE "id" = '1'

I can’t imagine situation when I would like on update null-ify other values.

Workaround is to set the fields option on the update function to Object.keys(req.body), worked for me, at least.
