越努力,越幸运!永远不要高估自己!

低调做人,高调做事!

明天开stark项目!!

 

admin 参考连接: http://www.cnblogs.com/yuanchenqi/articles/8323452.html

admin里面的一些配置

admin.py

from django.contrib import admin


from .models import *

# 带*的是必回的,其他了解,重点的注意 list_filter
class BookConfig(admin.ModelAdmin):
    list_display=["id","user","room","date","time_id"] # 不能放多对多字段   *
    list_display_links=["user"] # *
    list_filter=["user","room","date"]  #   *
    list_editable=["room"]  # 不能和list_display_links 重复

    #date_hierarchy = "date"
    #fields=["user","room"]
    #exclude=["user","room"]

    ordering=["date","time_id"]     # 排序

    # 定制Action行为具体方法    *
    def func(self, request, queryset):

        print(self, request, queryset)
        queryset.update(date="2012-12-12")

    func.short_description = "批量初始化操作"
    actions = [func, ]

class UserConfig(admin.ModelAdmin):
    list_display = ["username","tel"]
    list_filter = ["gf","username"]
    search_fields=["username","tel"]


admin.site.register(Book,BookConfig)

#print(admin.site._registry)

admin.site.register(UserInfo,UserConfig)
admin.site.register(Room)
admin.site.register(GF)

仿照admin的url注册:

就是一级分发到二级分发,然后返回一个([], None, None)

贴上源码

urls.py

from django.conf.urls import url
from django.contrib import admin
from app01 import views
from django.shortcuts import  HttpResponse

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")



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))
    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
         app_label=model._meta.app_label
         temp.append(url(r"%s/%s/"%(app_label,model_name),(get_urls2(),None,None)))


    return temp





urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^index/', views.index),
    url(r'^login/', views.login),
    url(r'^book/', views.book),


    url(r"^yuan/",(get_urls(),None,None))


]

复习面向对象知识

admin

使用

知识点1：

    url()的使用

    情况1：url(r'^book/', views.book),  # book(request)

    情况2 分发：
    url(r"^yuan/", ([
                        url(r'^test01/', ([
                                              url(r'^test04/', test04),
                                              url(r'^test05/', test05),
                                          ], None, None)),
                        url(r'^test02/', test02),
                        url(r'^test03/', test03),
                    ], None, None)
        )

知识点2：

    单例模式
        生成单例模式的方式：
        （1）使用 __new__
        （2）使用模块
             class A()
                pass
             a=A()

admin源码:

1 注册 admin.py

    admin.site.register(Book,BookConfig)

    源码：

        class AdminSite():
             def __init__(self, name='admin'):
                 self._registry = {}

             def register(self,model,admin_class):
                 if not admin_class:
                      admin_class = ModelAdmin

                 self._registry[model] = admin_class(model, self)



        site=AdminSite()



2 设计url

    如何通过model类变量获取该模型的字符串名称和该模型所在app的字符串名称：
    print("===>", model._meta.model_name)
    print("===>", model._meta.app_label)
