1. the built-in Admin of Django is a component provided for adding, deleting, modifying, and querying data tables in the model. The usage methods include:

1 dependent APP: 2 django. contrib. auth 3 django. contrib. contenttypes 4 django. contrib. messages 5 django. contrib. sessions 6 7 Template context_processors: 8 django. contrib. auth. context_processors.auth 9 django. contrib. messages. context_processors.messages10 11 middleware: 12 django. contrib. auth. middleware. authenticationMiddleware 13 django. contrib. messages. middleware. messageMiddleware

Django Admin internal dependency 2. Configure routes

1 urlpatterns = [2         url(r'^admin/', admin.site.urls),3     ]

You can create some route ing relationships for the current route:

/Admin/
/Admin/login/
/Admin/logout/
/Admin/password_change/
/Admin/password_change/done/

/Admin/app name/model name/
/Admin/app name/model name/add/
/Admin/app name/model name/ID value/history/
/Admin/app name/model name/ID value/change/
/Admin/app name/model name/ID value/delete/

3. Customize Admin

In admin. py, you only need to register a class in Mode to add the delete, modify, and query function in Admin. For example:

1 admin.site.register(models.UserInfo)

However, this method is relatively simple. To perform more custom operations, you need to use ModelAdmin, such:

Method 1: 2 class UserAdmin (admin. modelAdmin): 3 list_display = ('user', 'pwd',) 4 5 admin. site. register (models. userInfo, UserAdmin) # The first parameter can be list 6 7 8 Mode 2: 9 @ admin. register (models. userInfo) # The first parameter can be list 10 class UserAdmin (admin. modelAdmin): 11 list_display = ('user', 'pwd ',)

ModelAdmin provides a large number of customizable functions, such:

1. list_display: Custom columns displayed during the list.

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. You can click to jump to the Custom column during the list.

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

3. list_filter: the quick filter on the right side of the List is customized.

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 display filtering options 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. When you click query, filter 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

1 # pagination, number of entries per page 2 list_per_page = 1003 4 # pagination, show all (real data <only when this value is set) 5 list_max_show_all = 2006 7 # page plug-in 8 paginator = Paginator

6. list_editable: columns that can be edited during the list.

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

7. search_fields: Fuzzy search function in list

1 save_as_continue = True2 3 # If save_as = True and save_as_continue = True, click the "Sava as new" button to continue editing. 4 # If save_as = True and save_as_continue = False, click the "Sava as new" button and return to the list. 5 6 New in Django 1.10.
