I have some crucial application setup code that I want to run once on application spinup that requires iterating through classes of a certain type and calling a gem specific initialize method on them.
According to How can I preload concerns in a rails initializer using Rails 6/Zeitwerk? I should not autoload constants in initializers.
So how can I run code once on application load after classes are loaded
I tried with no luck:
config.after_initialize do
# do stuff
end
