Django 的時間格式處理範例

日期與時間永遠是專案中很重要的一部分，

今天就來介紹：

Django 的時間格式處理範例

Django 的 model 中，

Trac 1.2 裡 datepicker 每個禮拜的第一天改成星期天

Trac 1.2 裡 datepicker 每個禮拜的第一天改成星期天

在 Trac 1.0 搭配舊的 DateFieldPlugin 時，預設每週的第一天會是星期一，但這個設定可以在 trac.ini 內用 first_day 參數調整，像是這樣： [datefield] format = ymd separator = - first_day = 0 但在 Trac 1.2 在 trac.ini 裡就沒有提供設定讓人調整了… 而由於 Trac 是用 jQuery UI 的 Datepicker，在這個套件裡有提供方法讓人調整，所以解決的方向變成在 site.html 內用 JavaScript 處理，把這段程式碼塞到 JavaScript 的區段內就可以了： // Datepicker jQuery.datepicker.setDefaults({firstDay: 0}); 一整個繼續惡搞中… 然後把 wiki 上的 Trac 條目也更新上去。
