ruby - Rails engine doesn't eagerly load app files while seeding db -

i'm trying add together install task mountable engine units.

the task loads seed, , within clears table:

# lib/tasks/units_tasks.rake namespace :units task :install units::engine.load_seed end end # db/seeds.rb units::item.delete_all ...

when phone call task command line

$ bundle exec rake units:install # => nameerror: uninitialized constant units::item

the engine required usual (and gem works fine dependencies except case above).

# lib/units.rb require 'units/engine' module units end # lib/units/engine.rb module units class engine < ::rails::engine isolate_namespace units end end

obviously loaded without files, should eagerly loaded. why?

in seed method, need

require_relative '../lib/units'

or potentially

require_relative '../lib/units/engine'

then should able namespace have been previously.

i believe has threadsafe nature of rails, more technical reason beyond me.

ruby-on-rails ruby load rails-engines seed
