# Read about factories at https://github.com/thoughtbot/factory_girl

# It is a feature of our app that first signed up user is admin. This property
# is set in a before create callback `setup_role` in user model.
# We want to override this behavior when we create user factories. We want
# `create(:user)` to create non-admin user by default. We are enforcing it
# with `after create` blocks in following factories.
#
# Following commands won't work:
#       `create(:user, is_admin: true)`
#       `create(:admin, is_admin: false)`
#
# For a non-admin user, use: `create(:user)`
# For an admin user, use: `create(:admin)
