小的前兩天才入門Django 看著Django Girls的網站成功把example架了起來最近參考 http://drumcoder.co.uk/blog/2010/jun/13/monthly-calendar-django/ 這份範例想要把行事曆加入頁面中但是在調整Models的時候似乎出現了問題在 manage.py makemigrations的時候似乎因為int 沒有initial value 所以他請我輸入當時看他說明寫 datetime 也就照著打下去結果在更新的時候會出現 int() argument must be a string or a number, not 'datetime.datetime' 於是上網查詢了一下我修改了 0003 的migrate的資訊把 datetime改為 default=0; (也是唯一一個有看到datetime的migration file) Server可以正常run 但執行首頁會出現一樣的問題又google了一下把整個migration都清除 1. Erase every /migrations folder inside your apps 2. Go to the database and drop the **table name** table (or delete its rows) 整個清除之後重新執行 python manage.py migrate 可以看到兩張table有重新產生可是執行首頁依然出現 int() argument must be a string or a number, not 'datetime.datetime' 目前確定專案目錄下資料夾 migrations 已經不存在想請問是不是還有哪些地方有所遺漏以下附上部分錯誤訊息與 model程式碼 Request Method: GET Request URL: http://127.0.0.1:8000/ Django Version: 1.7.10 Exception Type: TypeError Exception Value: int() argument must be a string or a number, not 'datetime.datetime' Exception Location: /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/models/fields/__init__.py in get_prep_value, line 1601 Python Executable: /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python Python Version: 2.7.10 Python Path: ['/Users/kumashi/Desktop/share/django/mysite', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages', '/Library/Python/2.7/site-packages'] Server time: Thu, 1 Oct 2015 11:06:05 +0000 -------------------------------------------------------------------- #models.py class ContestEvent(models.Model): year = models.IntegerField(default=0) month = models.IntegerField(default=0) event_name = models.TextField(default="A") event_member = models.TextField(default="A") date_of_event = models.IntegerField(default=0) <=這欄位是被我誤填的 datetime為預設值的,現在修正為這樣感謝各位指點迷津 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 60.251.1.226 ※ 文章網址: https://www.ptt.cc/bbs/Python/M.1443698178.A.752.html ※ 編輯: panasonic89 (60.251.1.226), 10/01/2015 19:17:34
