Lazily convert an Enumerator or Enumerator::Lazy to a JSON array. Save as config/initializers/enumerator_to_json.rb
# Natively, Enumerators get JSONized like "#<Enumerator::Lazy:0x007f8714807080>", or they explode, either of which is a problem.
# We want them to make an array, and do it lazily so we don't have to keep the items in memory!

state.depth += 1
string = "[\n"
first_item = true
self.each do |item|

Optimistic and Pessimistic Locking in Rails

Optimistic Locking assumes that a database transaction conflict is very rare to happen. It uses a version number of the record to track the changes. It raise an error when other user tries to update the record while it is lock.

usage

Just add a lock_version column to the table you want to place the lock and Rails will automatically check this column before updating the record.

Pessimistic locking assumes that database transaction conflict is very likely to happen. It locks the record until the transaction is done. If the record is currently lock and the other user make a transaction, that second transaction will wait until the lock in first transaction is release.
