Error loading constant in non-alphabetical order

[fernandes]

Problem:

When you have two files like:

"app/concepts/thing/operation/enable.rb"
"app/concepts/thing/operation/update.rb"

and enable inheriting update

class Thing::Enable < Thing::Update

I got a NameError

Workaround

but if rename files to:

"app/concepts/thing/operation/aupdate.rb"
"app/concepts/thing/operation/enable.rb"

it works, I suspect its because Trailblazer::Loader loads in alphabetical order, makes sense?

trailblazer loader loads operation after all, but we are getting the error on Thing::Enable::Contract as shown on backtrace below

I'm gonna try to add a test (may I use fakefs on test?) but if you have any suggestion on how to workaround this heheh

I am not sure if it's better to simply do

require_dependency "user/operation/update"

class Enable < User::Update

instead of having to configure the loader. I think the default setup (alphabetical) covers 95% and some manual requires I don't see as a problem?

[fernandes]

I was facing some problems using require, I'm gonna test with require_dependency and if it persists I reopen, otherwise it's solved... thank you! :)

[apotonick]

require_dependency is the "Rails Way" and registers the constants for reloading, it actually works pretty well!

[fernandes]

yeah.. it seems to be working, thanks for the tip ;)
