eager evaluation

基本解釋

Eager evaluation can also help with the n+1 Selects Problem.
即時(shí)抓取還有助于解決 n+1 選擇問題。
But sometimes an association is always needed, in which case working with eager evaluation can make sense.
但是，有時(shí)候總是需要訪問某個(gè)關(guān)聯(lián)，在這種情況下使用即時(shí)抓取是有意義的。
But there's no way at query time to override an association to use the default eager evaluation techniques (second but immediate query).
但是，無法在查詢時(shí)覆蓋關(guān)聯(lián)來使用默認(rèn)的即時(shí)抓取技術(shù)（第二個(gè)查詢立即執(zhí)行）。
