Django實(shí)現(xiàn)學(xué)生管理系統(tǒng)

更新時(shí)間：2019年02月26日 10:10:58 作者：yaoliuwei1426

這篇文章主要為大家詳細(xì)介紹了Django實(shí)現(xiàn)學(xué)生管理系統(tǒng)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

Django學(xué)習(xí)筆記-學(xué)生管理系統(tǒng)（Django實(shí)現(xiàn)）筆記中僅實(shí)現(xiàn)了對(duì)數(shù)據(jù)的全部查詢。

下面實(shí)現(xiàn)新增、刪除、修改，代碼如下。

下面的代碼沒(méi)有對(duì)輸入框內(nèi)容進(jìn)行限制，如果輸入不符合規(guī)則的內(nèi)容，會(huì)出現(xiàn)錯(cuò)誤。

本篇更新完畢后Django更新暫停一段，由于工作崗位是測(cè)試工程師，后面將重點(diǎn)關(guān)注測(cè)試相關(guān)內(nèi)容。
