Simple shared directory via config

[merqlove]

Works well in my case.
Able to configure/reconfigure after or before default environment seed.

Sprig.configure do |config|
  config.shared_directory = 'shared'
end

Yes, ideally we need something with merge functional. But currently i found this case pretty useful.

Thanks @merqlove. Can you describe how you use this? Do you have apps where you want all your seeds to be the same for all your environments?

[merqlove]

@ltk Yeah, currently i have app where i have 100% identical seed. Later it will be splitted into two or more, but for now i want DRY :)

Seems that next iteration can fail if process depends on shared model.
But single call or call for different models works fine.

Example:

include Sprig::Helpers

Sprig.configure do | config|
  config.shared_directory = 'shared'
end

sprig [IdReservation, Genre, User, User::Profile, User::ProfileAvatar, User::Purse, SupportTicket, Page, Block,
       BlockPlace, Broadcast::Trailer, Broadcast::Trailer::Video, Broadcast, Broadcast::Background, Broadcast::Poster,
       Broadcast::Subscription, Broadcast::Ticket, Chat, SocialNetwork, SocialLink, Statistic]

# ...
# Sprig.configure do | config|
#  config.shared_directory = nil
# end

# sprig[Something]
#
