syl/utils/MyBaseModel.py增加抽象基類

from django.db import models 
class Base(models.Model): 
create_time = models.DateTimeField('創建時間', auto_now_add=True, null=True) 
update_time = models.DateTimeField('更新時間', auto_now=True, null=True) 
class Meta: 
abstract = True

from django.db import models
from utils.MyBaseModel import Base
# Create your models here.

class CourseType(Base):
    title=models.CharField('課程類別',max_length=16)
    sequence=models.IntegerField('展示順序',default=10)

    class Meta:
        db_table='tb_coursetype'

    def __str__(self):
        return self.title

class CourseTag(Base):
    title=models.CharField('課程標簽',max_length=16)
    sequence=models.IntegerField('展示順序',default=10)

    class Meta:
        db_table = 'tb_coursetag'

    def __str__(self):
        return self.title

class Course(Base):
    STATUS = (
    ('0', '即將上線'),
    ('1', '已上線'),
    ('2', '已下線'),
    )
    title = models.CharField('課程名', max_length=24)
    desc = models.CharField('課程描述', max_length=256)
    img = models.ImageField('課程logo', upload_to='course', null=True)
    course_type = models.ForeignKey(CourseType, verbose_name='課程類型',on_delete=models.SET_NULL, default=None, null=True)
    course_tag = models.ManyToManyField(CourseTag, verbose_name='課程標簽')
    status = models.CharField('課程狀態', choices=STATUS, max_length=8,default='1')
    attention = models.IntegerField('關注人數', default=0)
    learner = models.IntegerField('學習人數', default=0)

    class Meta:
        db_table = 'tb_course'

    def __str__(self):
        return self.title

2.課程章節表2張表

class Chapters(Base):
    title = models.CharField('章標題', max_length=24)
    serial_num = models.IntegerField('章序號')
    course = models.ForeignKey(Course, related_name='chapters',
    on_delete=models.SET_NULL, null=True)
    class Meta:
        db_table = 'tb_chapters'
    def __str__(self):
        return self.title

class Sections(Base):
    title = models.CharField('節標題', max_length=24)
    serial_num = models.IntegerField('節序號')
    chapters = models.ForeignKey(Chapters, related_name='sections',
    on_delete=models.SET_NULL, null=True)
    learn_time = models.IntegerField('學習小時', default=1)
    video = models.FileField("上傳視頻", upload_to="videos/%Y%m%d/", blank=True,max_length=1024)
    seq_num = models.IntegerField("序號", default=1)

    class Meta:
        db_table = 'tb_sections'

    def __str__(self):
        return self.title

3.course/admin.py注冊后臺管理

from django.contrib import admin 
from . import models 
admin.site.register(models.CourseType) 
admin.site.register(models.CourseTag) 
admin.site.register(models.Course) 
admin.site.register(models.Sections) 
admin.site.register(models.Chapters)

4.遷移表

python manage.py makemigrations 
python manage.py migrate
