Psych::AliasesNotEnabled: Alias parsing was not enabled. To enable it, pass aliases: true to Psych::load or Psych::safe_load. #725
Description
I have the following config/mongo.yml:
defaults: &defaults
host: 127.0.0.1:27017
options:
w: 1
pool_size: 1
slave_ok: false
ssl: false
development:
<<: *defaults
database: example_mongodb_development
test:
<<: *defaults
database: example_mongodb_test
w: 0
# set these environment variables on your prod server
production:
<<: *defaults
database: example_mongodb
username: <%= ENV['MONGO_USERNAME'] %>
password: <%= ENV['MONGO_PASSWORD'] %>I'd resolved to upgrade the app to ruby 3 and the default initializer from the mongomapper gem doesn't comply with a need for psych to pass an option called aliases with true as value, causing the error from the title.
