crm项目-stark组件

###############  admin基本认识和常用的定制功能    ###############

stark组件

对admin的基本认识
1，就是一个app，嵌入到了django里面，你可以在settings中看到
2，就是一个web后台管理工具，使用它可以更加的方便
3，通常我们在生成项目时会在 urls.py 中自动设置好url访问路径
urlpatterns = [
    url(r'^admin/', admin.site.urls)
]
4，启动开发服务器，然后在浏览器中访问 http://127.0.0.1:8000/admin/
5，你通过命令 python manage.py createsuperuser 来创建超级用户
6，使用的时候先注册数据模型：admin.site.register(models.UserInfo)
7，点击进入会展示数据，默认就是把这个对象打印出来，复杂的，需要定制的，需要利用ModelAdmin进行操作
class CourseConfig(admin.ModelAdmin):
    pass
admin.site.register(Course,CourseConfig)

#######################

class UserInfoConfig(admin.ModelAdmin):
    list_display=["id","name","username","password","email","depart"]  # 定制显示的列。不能放多对多的字段
    list_display_links=["username"]  # 定制列可以点击跳转到详情页面，
    list_filter=["depart"]  # 定制右侧快速筛选。
    list_editable=["email"]  # 可以编辑的列，可以编辑就不能是list_display_links字段了，
    search_fields=["username"]  # 模糊搜索的功能

    # 定义action的函数
    def func(self,request,queryset):
        print(request,queryset)
        queryset.update(email="1212@qq.com")
    func.short_description = "批量初始化操作"

    actions=[func,]  # 定制action中的操作
    fields=["username"]  # 查看详情和新增页面，可以控制显示的字段
    ordering=["-id"]  # 数据排序规则，倒序在字段前面加符号，

admin.site.register(UserInfo,UserInfoConfig)

###############  admin的url设计的基础知识点   ###############

admin的url是怎么设计的，这是核心，
urlpatterns = [
    url(r'^admin/', admin.site.urls),  # 为什么这一句能能够生成多条url，
]

第一个知识点，url的嵌套使用

def yuan(request):
    return HttpResponse("Yuan")

def test01(request):
    return HttpResponse("test01")

def test02(request):
    return HttpResponse("test02")

def test03(request):
    return HttpResponse("test03")

def test04(request):
    return HttpResponse("test04")

def test05(request):
    return HttpResponse("test05")

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^yuan/', ([
                        url(r'^test01/', ([
                                              url(r'^test04/', test04),  # http://127.0.0.1:8000/yuan/test01/test04/
                                              url(r'^test05/', test05),
                                          ], None, None)),
                        url(r'^test02/', test02),
                        url(r'^test03/', test03),
                    ], None, None))
]

第二个知识点：单例模式，

# 单例模式

# 一个类只允许实例一个对象

# class Singleton(object):
#     _instance = None
#     def __new__(cls, *args, **kw):
#         if not cls._instance:
#             cls._instance = super(Singleton, cls).__new__(cls, *args, **kw)
#         return cls._instance
#
# class MyClass(Singleton):
#     a = 1
#
#
# one = MyClass()
# one.a=3
#
# two = MyClass()
# print(two.a)  # 这个地方就是3，因为one和two指向的同一个内存空间，one改掉了a=3，所以two取值的时候就是3
#
# # print(one==two)
# # print(id(one),id(two))

# 第二种方法
###########################
# 第一个文件
class My_Singleton(object):
    x =12
    def foo(self):
        print(self.x)
my_singleton = My_Singleton()  # 这是一个关键的一步

print("OK")

###################
# 第二个文件
from mysingleton import my_singleton
def foo():
    print(id(my_singleton))
############
# 第三个文件
from mysingleton import my_singleton,My_Singleton

# a=My_Singleton()
# b=My_Singleton()
#
# print(id(a))
# print(id(b))  # 这是拿的类对象，而不是实例对象，所以，这两个不一样，

print(id(my_singleton))
from mysingleton import my_singleton
print(id(my_singleton))
from func import *
foo()  # 这三次都是拿的实例对象，所以id的结果都是一样的，

############### admin的url设计    ###############

第一个注册：

# 注册

self._registry = {}
self._registry[model] = admin_class(model, self)
# 注册的时候，是定义了一个字典，然后以model表为键，以对应的自定义类为值，生成对应的字典，

第二个url设置

def add(request):
    return HttpResponse("add")
def delete(request,id):
    return HttpResponse("delete")
def change(request,id):
    return HttpResponse("change")
def list_view(request):
    return HttpResponse("list_view")

def get_urls2():

    temp=[]
    temp.append(url(r"^add/",add))
    temp.append(url(r"^(\d+)/delete/",delete))
    temp.append(url(r"^(\d+)/change/",change))
    temp.append(url(r"^$",list_view))
    print("temp2",temp)
    # [
    # <RegexURLPattern None ^add/>,
    # <RegexURLPattern None ^(\d+)/delete/>,
    # <RegexURLPattern None ^(\d+)/change/>,
    # <RegexURLPattern None ^$>
    # ]
    return temp

def get_urls():

    temp=[]
    print("_registry",admin.site._registry)

    for model,admin_class_obj in admin.site._registry.items():
         print("model",model) # 所有的注册模型表

         # < class 'app01.models.Book'>----->     "book"  "app01"
         # < class 'app01.models.Room'>----->     "room"  "app01"
         print("===>",model._meta.model_name)
         print("===>",model._meta.app_label)

         model_name=model._meta.model_name  # 对应的model表的名字
         app_label=model._meta.app_label  # 对应的app名字
         temp.append(url(r"%s/%s/"%(app_label,model_name),(get_urls2(),None,None)))
    print("temp",temp)
    """
    [
    <RegexURLResolver <RegexURLPattern list> (None:None) auth/group/>,
    <RegexURLResolver <RegexURLPattern list> (None:None) auth/user/>,
    <RegexURLResolver <RegexURLPattern list> (None:None) crm/userinfo/>
    ]
    """

    return temp

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^yuan/', (get_urls(), None, None))
]

##############  stark组件需要实现的功能    ###############

在完成了注册和url设计之后，stark组件需要完成什么功能

1，查询页面
1.1 表头展示，可以定制展示的列，
1.2 表内容展示，删除 编辑，复选框的功能
1.3 查询功能，可以定义查询的字段，
1.4 action功能，可以定制批量操作
1.5 筛选功能，可以定制筛选的字段，
1.6 分页功能
这是最为复杂的部分，

2，新增页面
2.1 一个重要的pop功能，

3，删除页面
这个简单

4，编辑页面，
这个简单，和新增页面很相似，只需要把要编辑的数据带到页面展示，

整个重写，使用到了
1，django
2，admin
3，前端，js，html，bootstrap，jQuery，
