越努力,越幸運!永遠不要高估自己!

低調做人,高調做事!

明天開stark專案!!

admin 參考連線: http://www.cnblogs.com/yuanchenqi/articles/8323452.html

admin裡面的一些配置

admin.py

from django.contrib import admin


from .models import *

# 帶*的是必回的,其他了解,重點的注意 list_filter
class BookConfig(admin.ModelAdmin):
    list_display
 
=["id","user","room","date","time_id"] # 不能放多對多欄位   *
    list_display_links=["user"] # *
    list_filter=["user","room","date"]  #   *
    list_editable=["room"]  # 不能和list_display_links 重複

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

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

    # 定製Action行為具體方法    *
    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註冊:

就是一級分發到二級分發,然後返回一個([], None, None)

貼上原始碼

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) # 所有的註冊模型表

         # < 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))

複習面向物件知識

admin

使用

知識點1：

    url()的使用

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

    情況2 分發：
    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)
        )

知識點2：

    單例模式
        生成單例模式的方式：
        （1）使用 __new__
        （2）使用模組
             class A()
                pass
             a=A()

admin原始碼:

1 註冊 admin.py

    admin.site.register(Book,BookConfig)

    原始碼：

        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 設計url

    如何通過model類變數獲取該模型的字串名稱和該模型所在app的字串名稱：
    print("===>", model._meta.model_name)
    print("===>", model._meta.app_label)

def add(request):

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