篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Python CRM项目二相关的知识，希望对你有一定的参考价值。

一.准备工作

如果没有配置基本的项目,请参考 http://www.cnblogs.com/luhuajun/p/7771196.html

当我们配置完成后首先准备我们的app

创建2个app分别对应学生,重写的Admin模板

技术分享 
1 python manager.py startapp student  #学生视图
2 python manager.py startapp king_admin #king_admin视图
View Code

配置每个app的url映射

1.主app

技术分享 
1 #将每个模块的urls.py引入
2 urlpatterns = [
3     url(r‘^admin/‘, admin.site.urls),
4     url(r‘^crm/‘,include(‘crm.urls‘)),
5     url(r‘^student/‘,include(‘student.urls‘)),
6     url(r‘^king_admin/‘,include(‘king_admin.urls‘)),
7 ]
View Code

2.crm

技术分享 
1 urlpatterns = [
2     url(r‘^$‘,views.index,name=‘sales_index‘),#销售首页
3     url(r‘customers/‘,views.customer_list,name=‘customer_list‘),#客户库
4 ]
View Code

3.student

技术分享 
1 urlpatterns = [
2     #学生首页   
3     url(r‘^$‘,views.index,name=‘stu_index‘),
4 ]
View Code

4.king_admin

技术分享 
1 urlpatterns = [
2     #表首页
3     url(r‘^$‘,views.index,name=‘table_index‘),
4 ]
View Code

配置每个url的视图

1.crm

技术分享 
1 def index(request):
2     #返回销售首页
3     return render(request,‘index.html‘,name=‘sales_index‘)
4 
5 
6 def customer_list(request):
7     #返回客户库首页
8     return render(request,‘sales/customers.html‘)
View Code

2.student

技术分享 
1 def index(request):
2     #返回学生首页
3     return render(request,‘student/index.html‘)
View Code

3.king_admin

技术分享 
1 def index(request):
2     #返回表格管理页面
3     return render(request, ‘king_admin/table_index.html‘,{‘table_list‘:king_admin.enabled_admins})
View Code

配置前端页面

模板使用:http://v3.bootcss.com/examples/dashboard/

将上面的模板下载,将css,js,文件按一下的层级结构归类

技术分享

下载的html文件进行分解,分解为base.html和index.html

base.html存放css文件和js文件

index.html继承base.html然后在此基础上进行定制

base.html

然后在template下创个各个app名称的文件夹来存放不同app的页面,目录结构如下

 然后启动项目,看看每个url是否可以正常访问

准备数据

在插入数据之前,由于本项目要是用动态菜单,所以还要创建一张菜单表和角色表进行关联

技术分享 
 1 class Menu(models.Model):
 2     ‘‘‘菜单表‘‘‘
 3     name = models.CharField(max_length=32)
 4     url_name = models.CharField(max_length=64,unique=True)
 5 
 6     def __str__(self):
 7         return self.name
 8     class Meta:
 9         verbose_name_plural = ‘菜单‘
10 
11 
12 class Role(models.Model):
13     ‘‘‘角色表‘‘‘
14     name = models.CharField(max_length=64,unique=True)
15     #新增菜单信息
16     menus = models.ManyToManyField(‘Menu‘,blank=True)
17     def __str__(self):
18         return self.name
19 
20     class Meta:
21         verbose_name_plural = ‘角色‘

同步数据库,启动项目,进入admin后台管理

View Code

在此列出这些数据表,但是我们在Django admin自带的后台管理中,不需要插入中间表,系统会自动在中间表中关联,此处只是说明表关系

二.动态菜单的展示

在配置完数据之后,首先在页面的右上角展示登录的用户名,在左侧菜单根据不同的用户展示不同的明细

技术分享

 

因为userprofile中关联了Django自带的User,所以展示用户名只需要一行代码

在index.html中找到相应的行,替换即可

技术分享 
1 <a href="#" class="dropdown-toggle" data-toggle="dropdown" aria-expanded="false">{{ request.user }}</a>
View Code

因为在userprofile中已经关联了role,而role关联了菜单所以在前端可以直接循环userprofile来获取菜单

在index.html中找到相应的行,替换即可

技术分享 
1 {% for role in request.user.userprofile.roles.all %}
2                 {% for menu in role.menus.all %}
3                     <li><a href="{% url menu.url_name %}">{{ menu.name }}</a></li>
4                 {% endfor %}
5               {% endfor %}
View Code

这样动态菜单就设置完成

三.king_admin动态绑定models

因为我们要重写Django Admin的功能,所以首先分析Admin展示的数据结构

第一级是App

第二级是models

第三级是字段

技术分享

所以数据结构是

{app_name:{model_name:model_object,model_name1:model_object1,model_name2:model_object2....},}

这样的分层结构来封装数据,并返回给前端展示

根据类自动获取关联的表名和app名称

过程

技术分享 
1 #1.进入python交互环境
2 python manage.py shell
3 
4 #2.找到app名称
5 from crm import models
6 models.UserProfile._meta.app_config
7 
8 #3.找到表名
9 models.UserProfile._meta.app_label
View Code

核心代码:

技术分享 
1 def register(model_class,admin_class=None):
2     #如果不存再app,就新建一个字典,并且绑定admin_class和mode_class
3     if model_class._meta.app_label not in enabled_admins:
4         enabled_admins[model_class._meta.app_label] = {}
5     #绑定model对象和admin类,类似于admin的register方法
6     admin_class.model = model_class
7     #将字典的格式写成{app:{‘model_name‘:model_obj}}这种格式
8     enabled_admins[model_class._meta.app_label][model_class._meta.model_name] = admin_class
View Code
