一、表结构设计
from django.db import models # Create your models here. class UserInfo(models.Model): '''员工表''' username = models.CharField(max_length=64,verbose_name="用户名") password = models.CharField(max_length=32,verbose_name="用户密码") def __str__(self): return self.username class Meta: verbose_name_plural="员工表" class ClassList(models.Model): '''班级表''' title = models.CharField(max_length=32,verbose_name="班级名") def __str__(self): return self.title class Meta: verbose_name_plural = "班级表" class Student(models.Model): '''学生表''' name = models.CharField(max_length=32,verbose_name="学生姓名") password = models.CharField(max_length=32,verbose_name="学生密码") cls = models.ForeignKey(to="ClassList",verbose_name="所属班级") def __str__(self): return self.name class Meta: verbose_name_plural = "学生表" class Questionnaire(models.Model): '''问卷表''' title = models.CharField(max_length=32,verbose_name="问卷名") cls = models.ForeignKey(to="ClassList",verbose_name="问卷班级") create_user = models.ForeignKey(to="UserInfo",verbose_name="创建问卷的用户") def __str__(self): return self.title class Meta: verbose_name_plural = "问卷表" class Questions(models.Model): '''问卷问题表''' caption = models.CharField(max_length=32,verbose_name="问题题目") type_choices = ( (1,"打分"), (2,"单选"), (3,"评价") ) question_type = models.IntegerField(choices=type_choices,verbose_name="问题类型") questionnaire = models.ForeignKey(to="Questionnaire",verbose_name="所属问卷",default=1) def __str__(self): return self.caption class Meta: verbose_name_plural = "问卷问题表" class Answer(models.Model): '''问卷回答表''' #谁什么时候对那个问题作答了 student = models.ForeignKey(to="Student",verbose_name="所属学生") queston = models.ForeignKey(to="Questions",verbose_name="所属问题") option = models.ForeignKey(to="Option",null=True,blank=True) val = models.IntegerField(null=True,blank=True,verbose_name="数字答案") content = models.CharField(max_length=255,null=True,blank=True,verbose_name="文本答案") def __str__(self): return self.content class Meta: verbose_name_plural = "问卷回答表" class Option(models.Model): '''问卷单选题的选项表''' name = models.CharField(max_length=32,verbose_name="选项名") score = models.IntegerField(verbose_name="选项对应的分值") question = models.ForeignKey(to="Questions",verbose_name="所属问题") def __str__(self): return str(self.score) class Meta: verbose_name_plural = "问卷单选题的选项表"
