# NOTE: Why use Mysql2::Client / PG::Connection over ActiveRecord::Base.connection?
|
|
#
|
|
# As of Rails 5.2, db:create now runs initializers prior to creating the DB.
|
|
# That means if an initializer tries to establish an ActiveRecord::Base.connection,
|
|
# it will raise an ActiveRecord::NoDatabaseError
|
|
# (see https://github.com/rails/rails/issues/32870 for more details).
|
|
#
|
|
# The workaround is to use the bare RDBMS library
|
|
# and connect without specifying a database (MySQL),
|
|
# or connect to a standard system database instead (PostgreSQL).
