# If we're in development, also run this for the test environment.
|
|
# This is a somewhat hacky way to do this, so here's why:
|
|
# 1. We have to define this before we load the schema, or we won't
|
|
# have a timestamp_id function when we get to it in the schema.
|
|
# 2. db:setup calls db:schema:load_if_ruby, which calls
|
|
# db:schema:load, which we define above as having a prerequisite
|
|
# of this task.
|
|
# 3. db:schema:load ends up running
|
|
# ActiveRecord::Tasks::DatabaseTasks.load_schema_current, which
|
|
# calls a private method `each_current_configuration`, which
|
|
# explicitly also does the loading for the `test` environment
|
|
# if the current environment is `development`, so we end up
|
|
# needing to do the same, and we can't even use the same method
|
|
# to do it.
