Question

我在models.py文件中添加了新列，保存了我的代码，然后在Terminal我运行sudo python manage.py makemigrations music后跟sudo python manage.py migrate。运行sudo python manage.py migrate后，我在Terminal中收到错误消息：

这是我的index.html文件：

<!DOCTYPE html>
<html lang="en">
<head>
    <title>The Page</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

<body>


    <form class="col-md-4 col-md-offset-4" method="POST" name="formHandler">
        {% csrf_token %}
        <div class="userNameMovement">
            <label for="usr">Email:</label>
            <input class="form-control" id="email" name="email" placeholder="email" required="required">
        </div>

        <div class="passwordMovement">
            <label for="usr">Username:</label>
            <input class="form-control" id="userName" name="userName" placeholder="Username" required="required">
         <button type="submit" class="btn btn-default">Submit</button>
    </form>

    </body>
</html>

这是我的models.py文件：

from django.db import models

class Person(models.Model):
    email = models.CharField(max_length=20, default=4)
    userName = models.CharField(max_length=20, default=4)

    def __str__(self):
        return self.email + " - " + self.userName

class UI(models.Model):
    person = models.ForeignKey(Person, on_delete=models.CASCADE)

这是我的views.py文件：

from django.http import HttpResponse
from django.shortcuts import render
from .models import Person

def index(request):
    if request.method == 'POST':
        email = request.POST.get('email')
        userName = request.POST.get('userName')
        if email and userName:
            user = Person.objects.create(email=email, username=userName)
            user.save()
    return render(request, 'music/index.html')

def detail(request, user_id): # Testing out page 2
    return HttpResponse("<h2>Page # (testing this out) " + str(user_id) + "</h2>")

您发布的终端输出没有错误。它只是告诉你数据库中发生了什么。

除非有其他错误消息，否则一切都应该没问题。

为什么我的数据库不能工作？
