我的djangopost方法甚至被呼叫了嗎？-有解無憂

我正在嘗試在 Django 中制作交易日志應用程式，但遇到了一些障礙。當單擊提交按鈕時，感覺就像我的 post 方法可能會在晚上被呼叫。我嘗試過列印和記錄，但從未在 post() 方法中觸發。日志記錄在 get() 方法中作業正常。此外，即使我正在渲染 trading_log/add-order.html，我也會繼續被路由回我的基本索引頁面。我也嘗試過使用 HTTPResponseRedirect。兩者都無濟于事。我真的不確定我在這一點上做錯了什么。

由于我不確定需要查看哪些檔案，所以我現在將 repo 公開以嘗試獲得一些幫助。如果這不行或不允許，我可以洗掉鏈接。我還附上了下面帖子中要求的相關檔案。回購：https ://github.com/xcasper/caspers_trading_tools
