Question

Python 2.7版

Django版本1.11

尝试使我的第一个Django应用程序保存文档，这里是 models.py

的部分

class Docs(models.Model):
    FacilityRef = models.ForeignKey(Facility)
    Date = models.DateField(default=date.today)
    Type = models.CharField(max_length=50)
    Link = models.FileField(upload_to='Docs/%Y/%m/%d')

进行迁移时出现以下错误：

Date = models.DateField（default = date.today）NameError：name＆＃39; date＆＃39; 未定义

views.py 的一部分：

    from django.http import HttpResponse
    import datetime

models.py

的一部分

    from django.db import models
    import datetime

尝试在 views.py 和 models.py 中插入以下字符串，如其中所述 here and here 它没有帮助

from django.utils import timezone
from datetime import datetime

我应该做什么样的导入才能使这个功能起作用？

<?php $style= "required"; include('./classes/DB.php'); include('./classes/Login.php'); if (Login::isLoggedIn()) { echo 'is logged in'; if (isset($_POST['changepassword'])){ $oldpassword = $_POST['oldpassword']; $newpassword = $_POST['newpassword']; $newpasswordrepeat = $_POST['newpasswordrepeat']; $userid = Login::isLoggedIn(); if (password_verify($oldpassword, DB::query('SELECT password FROM users WHERE id=:userid', array(':userid'=>$userid))[0]['password'])) { if($newpassword == $newpasswordrepeat){ if (strlen($newpassword) >= 6 && strlen($newpassword) <= 60) { DB::query('UPDATE users SET password =:newpassword WHERE id=:userid', array(':newpassword'=>password_hash($newpassword, PASSWORD_BCRYPT), ':userid'=>$userid)); echo 'password changed succesfuly'; } }else{ echo 'password don\'t match'; } }else{ echo 'incorrect old password'; } } } else { $link= $_SERVER['REQUEST_URI']; $link_array = explode ('/' ,$link); $token = end($link_array); IF(DB::query('SELECT user_id FROM password_tokens where token=:token', array (':token'=>$token))[0]['user_id']){ $user_id = DB::query('SELECT user_id FROM password_tokens where token=:token', array (':token'=>$token))[0]['user_id']; echo $user_id; $style= "style= 'display:none'"; if (isset($_POST['changepassword'])){ $newpassword = $_POST['newpassword']; $newpasswordrepeat = $_POST['newpasswordrepeat']; if($newpassword == $newpasswordrepeat){ if (strlen($newpassword) >= 6 && strlen($newpassword) <= 60) { DB::query('UPDATE users SET password =:newpassword WHERE id=:userid', array(':newpassword'=>password_hash($newpassword, PASSWORD_BCRYPT), ':userid'=>$user_id)); } }else{ echo 'password don\'t match'; } } } else { die ('token invalid'); } } ?> <h1>change your password</h1> <form action="change_password.php" method="post"> <input type="password" name="oldpassword" value="" placeholder="Current password" <?php echo $style;?>></p> <input type="password" name="newpassword" value="" placeholder="New password ..." required></p> <input type="password" name="newpasswordrepeat" value="" placeholder="repeat password ..." required></p> <input type="button" name="changepassword" value="change password"> </form>是date模块的子模块。您永远不会导入名为datetime的模块，因此当您尝试调用它时会出现NameError。它应该是

date

DateField目前没有将date.today作为默认值
