Django的视图类读取数据

一 新建模型

from django.db import models
from django.contrib.auth.models import User
from slugify import slugify

class Course(models.Model):
    user = models.ForeignKey(User, related_name='courses_user')
    title = models.CharField(max_length=200)
    slug = models.SlugField(max_length=200, unique=True)
    overview = models.TextField()
    created = models.DateTimeField(auto_now_add=True)

    class Meta:
        ordering = ('-created',)

    def save(self, *args, **kargs):
        self.slug = slugify(self.title)
        super(Course, self).save(*args, **kargs)

    def __str__(self):
        return self.title

二 迁移数据库

(venv) E:\Django\mysite\mysite>python manage.py makemigrations
(venv) E:\Django\mysite\mysite>python manage.py migrate

三 编写类视图
