Try entering the container ./launcher enter app
then go into rails console:
rails c
create a new user:
new_user = User.create
then … and this will fail initially, try to save it (to instantiate it)
new_user.save!
follow the instructions on filling in the invalid attributes until it saves.
e.g.
new_user.username = 'frank'
will get past one validation error.
Rinse and repeat, eventually the user will save.
simply type new_user to see how far you’ve got but know you do not need to complete every field, only those with a validation issue.
Do not forget to save it, as new_user will be a temporary object until save works.
