再次学习Django，实现sql的页面显示及条件查询

# -*- coding: utf-8 -*-
 
from django.http import HttpResponse
from django.shortcuts import render_to_response
from django.db import connection
from django.shortcuts import render
from django.views.decorators import csrf
cursor = connection.cursor()
# 表单
def pagesprofile_form(request):
    return render_to_response('pages-profile.html')
 
# 接收请求数据
def pagesprofile(request):
    request.encoding = 'utf-8'
    if 'q' in request.GET:
        message = '你搜索的内容为: ' + request.GET['q']
        cursor.execute('select * from testdj_test')
        sql = cursor.fetchall()  # 读取所有
    else:
        message = '你提交了空表单'
    return HttpResponse(sql)

def dictfetchall(cursor):
    "将游标返回的结果保存到一个字典对象中"
    desc = cursor.description
    return [
    dict(zip([col[0] for col in desc], row))
    for row in cursor.fetchall()
    ]

def ReturnInfo(cursor):
    SqlDomain  = cursor.description
    DomainNum = len(SqlDomain)
    SqlDomainName = [None] * DomainNum
    for i in range(DomainNum):
        SqlDomainName[i] = SqlDomain [i][0]
    return SqlDomainName

# 接收POST请求数据
def search_post(request):
    global ctx_2
    cursor.execute('select * from testdj_test')
    #ctx = {}
    ctx_2 = dictfetchall(cursor)
    ctx = ReturnInfo(cursor)
    return render(request, "post.html", {'results': ctx, 'results_2': ctx_2})

html

<table class="table">
        <thead>
        <tr>
            {% for title in results%}
                <td>{{title}}</td>
            {% endfor%}
        </tr>
        </thead>
         <tbody>
          {% for item in results_2 %}
                <tr>
                {% for context in item.values %}
                <td>{{context}}</td>
                    {%endfor%}
              </tr>
         </tbody>
    {%endfor%}

Sql = "select * from %s where %s=%s" % (self.table, akey, avalue)
