数据库迁移：
python manage.py makemigrations
python manage.py migrate
创建超级用户：
name:admin
password:admin123456
渲染编辑页面
model_forms组件：
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("未找到符合要求的问卷")# 处理没有找到问卷调查对象的情况
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页渲染：
{% for questionModelForm in questionModelForm_list %}
<p>标题：{{ questionModelForm.caption }}</p>
<p>类型：{{ questionModelForm.question_type }}</p>
{% endfor %}
优化列表的low方法，采用生成器，原理参见（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("未找到符合要求的问卷") # 处理没有找到问卷调查对象的情况
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 %} 调查问卷 {% endblock %}
{% block content %}
{% for questionModelForm in generate_questionModelForm %}
<p>标题：{{ questionModelForm.caption }}</p>
<p>类型：{{ questionModelForm.question_type }}</p>
{% endfor %}
{% endblock %}
效果是一样的：
