end

.defer ⇒ Object

Defer safer_initialize checks queued inside the block until the block finishes, so associations preloaded by the enclosed queries are already resolved by the time the checks run (avoids N+1). Globals must not be mutated inside the block. On an exception the queue is discarded without flushing. Cannot be nested.
