數據庫設計
models.py
from django.db import models
from django.db import models
class UserInfo(models.Model):
"""
員工表
"""
name = models.CharField(max_length=32)
def __str__(self):
return self.name
class ClassInfo(models.Model):
"""
班級表
"""
name = models.CharField(max_length=32)
def __str__(self):
return self.name
class Student(models.Model):
"""
學生表
"""
user = models.CharField(max_length=32)
pwd = models.CharField(max_length=32)
cls = models.ForeignKey(to=ClassInfo)
def __str__(self):
return self.user
class Questionnaire(models.Model):
"""
問卷表
"""
title = models.CharField(max_length=64)
cls = models.ForeignKey(to=ClassInfo)
creator = models.ForeignKey(to=UserInfo)
def __str__(self):
return self.title
class Question(models.Model):
"""
問題表
"""
caption = models.CharField(max_length=64)
question_type = (
(1, ‘打分‘),
(2, ‘單選‘),
(3, ‘評價‘),
)
question_type = models.IntegerField(choices=question_type)
questionnaire = models.ForeignKey(Questionnaire, default=1)
def __str__(self):
return self.caption
class Option(models.Model):
"""
單選題的選項
"""
option_name = models.CharField(verbose_name=‘選項名稱‘, max_length=32)
score = models.IntegerField(verbose_name=‘選項對應的分值‘)
question = models.ForeignKey(to=Question)
def __str__(self):
return self.option_name
class Answer(models.Model):

student = models.ForeignKey(to=Student)
question = models.ForeignKey(to=Question)
# 三選一

content = models.CharField(max_length=255, null=True, blank=True)
數據庫遷移：
python manage.py makemigrations
python manage.py migrate
創建超級用戶：
name:admin
password:admin123456
渲染編輯頁面
model_forms組件：
from .models import *
from django.forms import ModelForm
class QuestionModelForm(ModelForm):
class Meta:
model = Question
fields = ["caption", "question_type"]
views.py用列表的low方法
from django.shortcuts import render, HttpResponse
from .models import *
from .model_forms import *
def questionnaire(request, questionnaire_id):
questionnaire_obj=Questionnaire.objects.filter(id=questionnaire_id).first()
if not questionnaire_obj:
return HttpResponse("未找到符合要求的問卷")# 處理沒有找到問卷調查對象的情況
question_list = Question.objects.filter(questionnaire_id=questionnaire_id)
questionModelForm_list=[]
for question in question_list:
questionModelForm=QuestionModelForm(instance=question)
questionModelForm_list.append(questionModelForm)
return render(request, ‘survey/questionnaire.html‘, locals())
html頁渲染：
{% for questionModelForm in questionModelForm_list %}
<p>標題：{{ questionModelForm.caption }}</p>
<p>類型：{{ questionModelForm.question_type }}</p>
{% endfor %}
優化列表的low方法，采用生成器，原理參見（http://www.cnblogs.com/0bug/p/8183629.html）：
def questionnaire(request, questionnaire_id):
questionnaire_obj = Questionnaire.objects.filter(id=questionnaire_id).first()
if not questionnaire_obj:
return HttpResponse("未找到符合要求的問卷") # 處理沒有找到問卷調查對象的情況
def generate_questionModelForm():
question_list = Question.objects.filter(questionnaire_id=questionnaire_id)
for question in question_list:
questionModelForm = QuestionModelForm(instance=question)
yield questionModelForm
return render(request, ‘survey/questionnaire.html‘, {"generate_questionModelForm": generate_questionModelForm()})
html渲染
{% extends ‘base.html‘ %}
{% block title %} 調查問卷 {% endblock %}
{% block content %}
{% for questionModelForm in generate_questionModelForm %}
<p>標題：{{ questionModelForm.caption }}</p>
<p>類型：{{ questionModelForm.question_type }}</p>
{% endfor %}
{% endblock %}
