django  內置 Adminhtml

Django內置的Admin是對於model中對應的數據表進行增刪改查提供的組件,使用方式有:python

 1 依賴APP:
 2         django.contrib.auth
 3         django.contrib.contenttypes
 4         django.contrib.messages
 5         django.contrib.sessions
 6 
 7     模板的context_processors:
 8         django.contrib.auth.context_processors.auth
 9         django.contrib.messages.context_processors.messages
10 
11     中間件:
12         django.contrib.auth.middleware.AuthenticationMiddleware 
13         django.contrib.messages.middleware.MessageMiddleware
14 
15 Django Admin內部依賴
View Code

一. 配置路由

urlpatterns = [django

         url(r '^admin/' , admin.site.urls),
     ]
 
當前配置的路由能夠建立一些路由映射關係:
 

二. 定製Admin

在admin.py中只須要講Mode中的某個類註冊,便可在Admin中實現增刪改查的功能,如:session

1 admin.site.register(models.UserInfo)

 

 可是,這種方式比較簡單,若是想要進行更多的定製操做,須要利用ModelAdmin進行操做,如:app

方式一:
    class UserAdmin(admin.ModelAdmin):
        list_display = ('user', 'pwd',)
 
    admin.site.register(models.UserInfo, UserAdmin) # 第一個參數能夠是列表
     
 
方式二:
    @admin.register(models.UserInfo)                # 第一個參數能夠是列表
    class UserAdmin(admin.ModelAdmin):
        list_display = ('user', 'pwd',)

  

ModelAdmin中提供了大量的可定製功能,如ide

1. list_display,列表時,定製顯示的列ui

 

1 @admin.register(models.UserInfo)
2 class UserAdmin(admin.ModelAdmin):
3     list_display = ('user', 'pwd', 'xxxxx')
4  
5     def xxxxx(self, obj):
6         return "xxxxx"

2. list_display_links,列表時,定製列能夠點擊跳轉。url

1 @admin.register(models.UserInfo)
2 class UserAdmin(admin.ModelAdmin):
3     list_display = ('user', 'pwd', 'xxxxx')
4     list_display_links = ('pwd',)

3. list_filter,列表時,定製右側快速篩選spa

 1 from django.utils.translation import ugettext_lazy as _
 2  
 3 @admin.register(models.UserInfo)
 4 class UserAdmin(admin.ModelAdmin):
 5     list_display = ('user', 'pwd')
 6  
 7     class Ugg(admin.SimpleListFilter):
 8         title = _('decade born')
 9         parameter_name = 'xxxxxx'
10  
11         def lookups(self, request, model_admin):
12             """
13             顯示篩選選項
14             :param request:
15             :param model_admin:
16             :return:
17             """
18             return models.UserGroup.objects.values_list('id', 'title')
19  
20         def queryset(self, request, queryset):
21             """
22             點擊查詢時,進行篩選
23             :param request:
24             :param queryset:
25             :return:
26             """
27             v = self.value()
28             return queryset.filter(ug=v)
29  
30     list_filter = ('user',Ugg,)

4. list_select_related,列表時,連表查詢是否自動select_related插件

5. 分頁相關

1 # 分頁,每頁顯示條數
2     list_per_page = 100
3  
4 # 分頁,顯示所有(真實數據<該值時,纔會有顯示所有)
5     list_max_show_all = 200
6  
7 # 分頁插件
8     paginator = Paginator

6. list_editable,列表時,能夠編輯的列

1 @admin.register(models.UserInfo)
2 class UserAdmin(admin.ModelAdmin):
3     list_display = ('user', 'pwd','ug',)
4     list_editable = ('ug',)

7. search_fields,列表時,模糊搜索的功能

3 # 若是 save_as=True,save_as_continue = True, 點擊Sava as new 按鈕後繼續編輯。
4 # 若是 save_as=True,save_as_continue = False,點擊Sava as new 按鈕後返回列表。
5  
6 New in Django 1.10.

12. save_on_top = False,詳細頁面,在頁面上方是否也顯示保存刪除等按鈕

13. inlines,詳細頁面,若是有其餘表和當前表作FK,那麼詳細頁面能夠進行動態增長和刪除
