今天我試圖使用ActiveModelSerializers設置緩存。我遇到了很多問題（我的連接保持超時）。所以我試圖恢復所有的更改，包括刪除我正在處理的分支。如何退出ActiveModelSerializers中的緩存？
但是，自從我嘗試設置緩存以來，我一直在使用的模型展現出奇怪的行爲。看起來它仍在加載緩存元素。嘗試訪問該模型的端點時，這會造成巨大的性能下降。

的[active_model_serializers]負荷和高速緩存是新的東西，導致我相信串行仍試圖從緩存中加載。
我的其他模型，我沒有觸及只有一個[active_model_serializers]聲明的負載，這是我預期的行爲。

正如你所看到的，那些額外的訪問數據庫會減慢我的加載時間。這些模型現在都有大約3個對象，但是當我用更多的記錄進行測試時，這成爲一個巨大的問題。
如何強制ActiveModelSerializer忽略緩存項目？
更好的選擇是弄清楚這些碎片在哪裏被緩存，所以我可以將它們清除。我試過Rails.cache.clear，但是這沒有效果。我也嘗試過，重新啓動計算機，並關閉Redis實例。
