I am developing using Rails, Docker, and MySQL.
The version is as follows.
Development environment
Ruby vresion 2.7.2
Rails version 6.0.3.4
MySQL version 5.7
We are currently creating a table for users.
Next, I'm trying to create a table (review table) that uses user as a foreign key.
docker-compose run web rails db: migrate
If i do, you will get an error.
Would you please help me?
Error message(Since the number of characters has been limited, some parts have been omitted.)
rails aborted!
StandardError: An error has occurred, all later migrations canceled:
