join twice on the same table rails?

Question

I want to join on the same table twice to get username and username_to

@array = UsersWalletsBalancesFrozen.
joins("INNER JOIN userds userdsidto ON transactions.user_id_to=userdsidto.id").
joins("INNER JOIN userds userdsid   ON transactions.user_id = userdsid.id").select("*")

This get me the last join only works i think it's overrides is there any solution to that

Answer 1

Just as a quick solution... Have you tried to put it in the same method call:

@array = UsersWalletsBalancesFrozen.joins("INNER JOIN userds AS user_to userdsidto ON transactions.user_id_to=user_to.id INNER JOIN userds userdsid AS user_from   ON transactions.user_id = user_from.id").select("transactions.*, user_to.username, user_from.username")

?

PS: select('*') will be called by default. No need to explicitly specify it.
