5,609 PointsDatabase gives "rollback transaction" on Rails Console .create method on Rails 5.
I keep getting this when I follow along
2.3.0 :008 > TimeEntry.create(time:1.2, customer_id: 2)
(0.1ms) begin transaction
Customer Load (0.1ms) SELECT "customers".* FROM "customers" WHERE "customers"."id" = ? LIMIT ? [["id", 2], ["LIMIT", 1]]
(0.1ms) rollback transaction
=> #<TimeEntry id: nil, time: 1.2, customer_id: 2, employee_id: nil, created_at: nil, updated_at: nil>
I am using Ruby 2.3.0 and Rails 5. He said it shouldn't matter, but I realize that was talking about prior versions.

5,609 PointsThe issue actually comes because It's Rails 5, actually.
Rails, in 5.0, requires validation on belongs_to. There are two ways to fix it, adding optional: true or required: false.
This code fixed my issue with committing to the DB, but I'm going to have to do some reading to see how this changes the way I've seen associations.
If you're interested, http://blog.bigbinary.com/2016/02/15/rails-5-makes-belong-to-association-required-by-default.html has a way to revert the behavior back to the functionality we were used to in Rails 4.x.
