models.py

设计思路：

作业列表页

urls.py

from django.conf.urls import url,include
from student import views

urlpatterns = [
    url(r'^my_homework/$', views.homework_list,name='my_homework'),
]

models.py

from django.db import models
import datetime

class Homework(models.Model):
    """作业模板"""
    title = models.CharField(max_length=32, verbose_name='作业标题')
    desc = models.TextField(verbose_name='作业需求')
    scoring_point = models.TextField(verbose_name='得分点')
    publish_date = models.DateField(auto_now_add=True,verbose_name='发布日期')
    suggested_complete_days = models.IntegerField(verbose_name='完成天数')
    

from crm.models import Student

class HomeworkRecord(models.Model):
    """学生作业记录"""
    homework = models.ForeignKey('Homework')
    student = models.ForeignKey(Student,verbose_name='学生',null=True,blank=True)
    status_choices = ((0,'未提交'),(1,'待批改'),(2,'已批改'),(3,'迟交'))
    status = models.SmallIntegerField(verbose_name='作业状态',choices=status_choices)
    teacher_comments = models.TextField(verbose_name='导师点评',null=True,blank=True)
    score = models.SmallIntegerField(verbose_name='分数',default=0)
    upload_time = models.DateTimeField(verbose_name='提交时间',null=True,blank=True)
    

class Student(models.Model):
    """学生"""
    student = models.OneToOneField('StudentEnrollment')  # 只有走完报名流程才会成为正式学员
    user_account = models.OneToOneField('UserProfile')  # 创建用户

手动在后台中学生对象:

• 1、后台中创建学生
• 2、注册新用户userprofile；
• 3、进入后台为userprifile指定角色；
• 4、创建student指定关联的学生 和 userprofile

手动在后台中给学生对象 分配 作业
