Django CRM客户关系管理系统

CRM需求分析

    随着信息化时代带来的科技创新，CRM客户关系管理系统带来的效益在已经成为很多企业提高竞争优势的一分部，CRM客户关系管理系统将企业管理和客户关系管理集成到统一的平台，其系统功能主要体现在企业与客户之间的业务和企业内部之前部门之间的业务。因此CRM客户关系管理系统不但可以记录企业自内部信息，对于客户信息存储也是可以做到的，其中还涉及市场竞争对手的情报资料，还包括了企业进行营销、销售及支持服务所需的各种数据。

功能实现

　　(1)建议统一的信息编码系统;

　　(2)设计能够良好反映事物特性的数据模型;

　　(3)划分数据库管理，在分布式数据库管理系统和网络平台基础上，涉及全局共享及局部共享数据库，以支持分布式数据处理，实现各分系统之间及其内部各功能模块之间的信息集成。

　　(4)提供强大的数据库管理系统，并在此基础上增加拿过来的完善的客户销售数据库、客户市场数据库、客户支持与服务数据库、企业综合信息数据库等。

  CRM客户关系管理系统的管理理念始终是以客户为中心的，不同的管理系统有着自己不同的数据处理方式，因此企业在构建自己的客户关系管理数据库时需要注意系统的特性和其他企业管理软件的协调。

  对于中小型企业在客户关系管理系统上的应用，可有助于企业对客户信息管理混乱状态的改善，加强了企业和客户之间的联系，因此下面是中小企业在面对客户关系管理系统时所需的需求：

 　　(1)因为是小型企业，系统将只设系统管理员，管理员拥有对企业全部系统资料的操作权限。

　　 (2)客户管理模块，基本资料的添加、修改、删除和查询功能;与客户相关的联系人资料的添加、修改、删除和查询功能。另外，当查询到需要信息的时候，系统应提供报表和打印功能，以供公司领导作出决策。

　 　(3)客户销售管理模块，有基本的添加、修改、删除和查询功能。其目标是提高客户销售数据的准确性、及时性和完整性，对客户销售进行有效管理，提供决策支持所需的数据。

     (4)服务反馈模块，有基本的添加、修改、删除和查询功能，其目标是及时记录客户反馈的信息，提供有竞争力的售后支持、修理和维护服务

好了 开始写项目吧！

    首先创建django项目：

            环境：Python3

            工具： pycharm

            用到的插件：jquery bootsharp

• 创建项目：
• 根据关系编写model 认证方式继承于django自带认证from django.contrib.auth.models import User

from django.db import models

• OK 先来登陆admin吧 

• 接下来创建几条数据吧！ 

数据创建完成了，但是我们发现了一个问题，我们创建了那么多字段为什么只而admin只显示了主键字段，这样的话查看数据就非常的不方便，因此我们就需要对admin进行定制了！

        我们继续修改crm/admin.py

class CustomerAdmin(admin.ModelAdmin):
    list_display = ('id','qq','source','consultant','content','status','date')
    list_filter = ('source','consultant','date')
    search_fields = ('qq','name')
    raw_id_fields = ('consult_course',)
    filter_horizontal = ('tags',)
    list_editable = ('status',)
class UserProfileAdmin(admin.ModelAdmin):
    list_display = ('user','name')
admin.site.register(models.Customer,CustomerAdmin)
admin.site.register(models.UserProfile,UserProfileAdmin)

     效果显而易见 

编写自己的admin 管理系统
