[django]手动数据库备份

来源:互联网 作者:佚名 时间:2017-09-08 09:51
基本原理是按钮点击后,系统查询出数据表中信息,然后在网页中导出相关表格! 若有自动数据库备份的兄弟,指点一下! 模板代码: a href ="{% url 'work_backup' %}" class ="btn btn-primary btn-sm" type ="button" 数据备份 / a url代码: keywork_patterns = [

基本原理是按钮点击后,系统查询出数据表中信息,然后在网页中导出相关表格!

若有自动数据库备份的兄弟,指点一下!

模板代码:

<a href="{% url 'work_backup' %}" class="btn btn-primary btn-sm" type="button">数据备份</a>

url代码:

keywork_patterns = [
    url(r'^backup/$', 'keywork.views.work_backup', name='work_backup'),
]
urlpatterns = [
    url(r'^$', 'login.views.login_view', name='login_view'),
    # url(r'^blog/', include('blog.urls')),
    url(r'^keywork/', include(keywork_patterns)),
    url(r'^admin/', include(admin.site.urls)),
]

view代码:

def work_backup(request):
    response = HttpResponse(content_type='application/vnd.ms-excel') 
    response['Content-Disposition'] = 'attachment; filename=beifen'+time.strftime('%Y%m%d',time.localtime(time.time()))+'.xls' 
    workbook = xlwt.Workbook(encoding='utf-8') #创建工作簿
    sheet = workbook.add_sheet("sheet1") #创建工作页
    row0 = [u'用户标识',u'设备状态',u'用户号码',u'用户姓名',u'账户编码',
            u'产品ID',u'支局名称',u'支局ID',u'区域名称',u'区域ID',
            u'网格名称',u'销售人员名称',u'销售点名称',u'号码竣工时间',u'号码拆机时间',
            u'用户类型',u'产品其他标识',u'服务提供ID',u'服务提供名称',u'CRM竣工时间',
            u'CRM受理员工',u'CRM受理工号',u'受理点',u'销售贫名称',u'统计时间'
            ]
    for i in range(0,len(row0)):
        sheet.write(0,i,row0[i])
    data = DevData.objects.values()
    num = 1
    for d in data:
        sheet.write(num,0,d['serv_id'])
        sheet.write(num,1,d['serv_state_name'])
        sheet.write(num,2,d['acc_nbr'])

        sheet.write(num,18,d['service_offer_name'])

        sheet.write(num,20,d['staff_name'])
        sheet.write(num,21,d['staff_code'])
        sheet.write(num,22,d['org_name'])
        sheet.write(num,23,d['prod_offer_name'])
        sheet.write(num,24,d['day_id'])
        num = num + 1
    workbook.save(response)    
    return response
