Django之内置Admin
目录
一、说明
Django内置的Admin是对于model中对应的数据表进行增删改查提供的组件，使用方式有：
1、使用方式
依赖APP：
django.contrib.auth
django.contrib.contenttypes
django.contrib.messages
django.contrib.sessions
模板的context_processors：
django.contrib.auth.context_processors.auth
django.contrib.messages.context_processors.messages
中间件：
django.contrib.auth.middleware.AuthenticationMiddleware
django.contrib.messages.middleware.MessageMiddleware
2、配置路由
urlpatterns = [ url(r'^admin/', admin.site.urls), ]
当前配置的路由可以创建一些路由映射关系：
/admin/
/admin/login/
/admin/logout/
/admin/password_change/
/admin/password_change/done/
/admin/app名称/model名称/
/admin/app名称/model名称/add/
/admin/app名称/model名称/ID值/history/
/admin/app名称/model名称/ID值/change/
/admin/app名称/model名称/ID值/delete/
二、Admin的参数及使用
1、使用
在admin.py中只需要将Model中的某个类注册，即可在Admin中实现增删改查的功能，如：
admin.site.register(models.UserInfo)
但是，这种方式比较简单，如果想要进行更多的定制操作，需要利用ModelAdmin进行操作，如：
from django.contrib import admin 方式一： class UserAdmin(admin.ModelAdmin): list_display = ('user', 'pwd',) admin.site.register(models.UserInfo, UserAdmin) # 第一个参数可以是列表 ''' admin.site.register([models.UserGroup,models.Role],admin.ModelAdmin) # admin.site.register(models.UserGroup,admin.ModelAdmin) # admin.site.register(models.Role,admin.ModelAdmin) ''' 方式二： @admin.register(models.UserInfo) # 第一个参数可以是列表 class UserAdmin(admin.ModelAdmin): list_display = ('user', 'pwd',)
2、参数说明
ModelAdmin中提供了大量的可定制功能，如
1. list_display，列表时，定制显示的列。
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): list_display = ('user', 'pwd', 'xxxxx') def xxxxx(self, obj): return "xxxxx"
2. list_display_links，列表时，定制列可以点击跳转。
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): list_display = ('user', 'pwd', 'xxxxx') list_display_links = ('pwd',)
3. list_filter，列表时，定制右侧快速筛选。
from django.utils.translation import ugettext_lazy as _ @admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): list_display = ('user', 'pwd') class Ugg(admin.SimpleListFilter): title = _('decade born') parameter_name = 'xxxxxx' def lookups(self, request, model_admin): """ 显示筛选选项 :param request: :param model_admin: :return: """ return models.UserGroup.objects.values_list('id', 'title') def queryset(self, request, queryset): """ 点击查询时，进行筛选 :param request: :param queryset: :return: """ v = self.value() return queryset.filter(ug=v) list_filter = ('user',Ugg,)
4. list_select_related，列表时，连表查询是否自动select_related
5. 分页相关
# 分页，每页显示条数 list_per_page = 100 # 分页，显示全部（真实数据<该值时，才会有显示全部） list_max_show_all = 200 # 分页插件 paginator = Paginator
6. list_editable，列表时，可以编辑的列
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): list_display = ('user', 'pwd','ug',) list_editable = ('ug',)
7. search_fields，列表时，模糊搜索的功能
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): search_fields = ('user', 'pwd')
8. date_hierarchy，列表时，对Date和DateTime类型进行搜索
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): date_hierarchy = 'ctime'
9. preserve_filters，详细页面，删除、修改，更新后跳转回列表后，是否保留原搜索条件
10. save_as = False，详细页面，按钮为“Sava as new” 或 “Sava and add another”
11. save_as_continue = True，点击保存并继续编辑
save_as_continue = True # 如果 save_as=True，save_as_continue = True， 点击Sava as new 按钮后继续编辑。 # 如果 save_as=True，save_as_continue = False，点击Sava as new 按钮后返回列表。 New in Django 1.10.
12. save_on_top = False，详细页面，在页面上方是否也显示保存删除等按钮
13. inlines，详细页面，如果有其他表和当前表做FK，那么详细页面可以进行动态增加和删除
class UserInfoInline(admin.StackedInline): # TabularInline extra = 0 model = models.UserInfo class GroupAdminMode(admin.ModelAdmin): list_display = ('id', 'title',) inlines = [UserInfoInline, ]
14. action，列表时，定制action中的操作
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): # 定制Action行为具体方法 def func(self, request, queryset): print(self, request, queryset) print(request.POST.getlist('_selected_action')) func.short_description = "中文显示自定义Actions" actions = [func, ] # Action选项都是在页面上方显示 actions_on_top = True # Action选项都是在页面下方显示 actions_on_bottom = False # 是否显示选择个数 actions_selection_counter = True
15. 定制HTML模板
add_form_template = None change_form_template = None change_list_template = None delete_confirmation_template = None delete_selected_confirmation_template = None object_history_template = None
16. raw_id_fields，详细页面，针对FK和M2M字段变成以Input框形式
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): raw_id_fields = ('FK字段', 'M2M字段',)
17. fields，详细页面时，显示字段的字段
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): fields = ('user',)
18. exclude，详细页面时，排除的字段
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): exclude = ('user',)
19. readonly_fields，详细页面时，只读字段
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): readonly_fields = ('user',)
20. fieldsets，详细页面时，使用fieldsets标签对数据进行分割显示
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): fieldsets = ( ('基本数据', { 'fields': ('user', 'pwd', 'ctime',) }), ('其他', { 'classes': ('collapse', 'wide', 'extrapretty'), # 'collapse','wide', 'extrapretty' 'fields': ('user', 'pwd'), }), )
21. 详细页面时，M2M显示时，数据移动选择（方向：上下和左右）
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): filter_vertical = ("m2m字段",) # 或filter_horizontal = ("m2m字段",)
22. ordering，列表时，数据排序规则
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): ordering = ('-id',) 或 def get_ordering(self, request): return ['-id', ]
23. view_on_site，编辑时，是否在页面上显示view on set
view_on_site = False 或 def view_on_site(self, obj): return 'https://www.baidu.com'
24. radio_fields，详细页面时，使用radio显示选项（FK默认使用select）
radio_fields = {"ug": admin.VERTICAL} # 或admin.HORIZONTAL
25. show_full_result_count = True，列表时，模糊搜索后面显示的数据个数样式
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): # show_full_result_count = True # 1 result (12 total) # show_full_result_count = False # 1 result (Show all) search_fields = ('user',)
26. formfield_overrides = {}，详细页面时，指定现实插件
from django.forms import widgets from django.utils.html import format_html class MyTextarea(widgets.Widget): def __init__(self, attrs=None): # Use slightly better defaults than HTML's 20x2 box default_attrs = {'cols': '40', 'rows': '10'} if attrs: default_attrs.update(attrs) super(MyTextarea, self).__init__(default_attrs) def render(self, name, value, attrs=None): if value is None: value = '' final_attrs = self.build_attrs(attrs, name=name) return format_html('<textarea {}>\r\n{}</textarea>',final_attrs, value) @admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): formfield_overrides = { models.models.CharField: {'widget': MyTextarea}, }
27. prepopulated_fields = {}，添加页面，当在某字段填入值后，自动会将值填充到指定字段。
PS: DjangoAdmin中使用js实现功能，页面email字段的值会在输入：user、pwd时自动填充
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): prepopulated_fields = {"email": ("user","pwd",)}
28. form = ModelForm，用于定制用户请求时候表单验证
from app01 import models from django.forms import ModelForm from django.forms import fields class MyForm(ModelForm): others = fields.CharField() class Meta: model = models = models.UserInfo fields = "__all__" @admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): form = MyForm
29. empty_value_display = "列数据为空时，显示默认值"
@admin.register(models.UserInfo) class UserAdmin(admin.ModelAdmin): empty_value_display = "列数据为空时，默认显示" list_display = ('user','pwd','up') def up(self,obj): return obj.user up.empty_value_display = "指定列数据为空时，默认显示"
三、实例
from django.db import models class UserGroup(models.Model): title = models.CharField(max_length=32) def __str__(self): return self.title class Role(models.Model): name = models.CharField(max_length=32) def __str__(self): return self.name class UserInfo(models.Model): user = models.CharField(max_length=32) email = models.EmailField() age = models.IntegerField(default=0) gender_choice = ( (0,"F"), (1,"M"), ) gender = models.IntegerField(choices=gender_choice,blank=True,null=True) ug = models.ForeignKey(UserGroup,null=True,blank=True,on_delete=models.CASCADE) m2m = models.ManyToManyField("Role") def __str__(self): return self.user
1. list_display，列表时，定制显示的列。

9. preserve_filters，详细页面，删除、修改，更新后跳转回列表后，是否保留原搜索条件
默认preserver_filters = True的。
from django.contrib import admin from app01 import models class UserInfoAdmin(admin.ModelAdmin): list_display = ("user","email","age","gender","create") # 仅显示这3项，不显示其他如m2m # list_display_links = ("user","email",) list_filter = ("user", "email","gender") # list_per_page = 3 # 每页显示数量 # list_max_show_all = 4 # 低于多少可以出现按钮显示所有 # list_editable = ("email","age","gender") # 除了list_display_links的列，因为需要点击，所以不能为input框 # search_fields = ("user","email","age","gender") # 模糊搜索 # date_hierarchy = "create" # 指向字段create preserve_filters = False # 默认是True，保留筛选条件。 admin.site.register(models.UserInfo,UserInfoAdmin)
修改前，筛选dage，修改该条目age为20
修改后，筛选条件不见了，显示全部
10. save_as = False，详细页面，按钮为“Save as new” 或 “Save and add another”。与save_as_continue一起使用

显示出了user的其他item
19. readonly_fields，详细页面时，只读字段
from django.contrib import admin from app01 import models # # class UserInfoInline(admin.StackedInline): # TabularInline # extra = 0 # model = models.UserInfo # # class GroupAdminMode(admin.ModelAdmin): # list_display = ('id', 'title',) # inlines = [UserInfoInline, ] class UserInfoAdmin(admin.ModelAdmin): list_display = ("user","email","age","gender","create") # 仅显示这3项，不显示其他如m2m # list_display_links = ("user","email",) # list_filter = ("user", "email","gender") # list_per_page = 3 # 每页显示数量 # list_max_show_all = 4 # 低于多少可以出现按钮显示所有 # list_editable = ("email","age","gender") # 除了list_display_links的列，因为需要点击，所以不能为input框 # search_fields = ("user","email","age","gender") # 模糊搜索 # date_hierarchy = "create" # 指向字段create # preserve_filters = False # 默认是True，保留筛选条件。 # save_as = True # save_as_continue = True # save_on_top = True # raw_id_fields = ("ug","m2m") # fields = ('user',"gender",) # exclude = ('user',) readonly_fields = ('user',"gender") admin.site.register(models.UserInfo,UserInfoAdmin)
把user、gender改为只读字段
20. fieldsets，详细页面时，使用fieldsets标签对数据进行分割显示

24. radio_fields，详细页面时，使用radio显示选项（FK默认使用select）
from django.contrib import admin from app01 import models # # class UserInfoInline(admin.StackedInline): # TabularInline # extra = 0 # model = models.UserInfo # # class GroupAdminMode(admin.ModelAdmin): # list_display = ('id', 'title',) # inlines = [UserInfoInline, ] class UserInfoAdmin(admin.ModelAdmin): list_display = ("user","email","age","gender","create") # 仅显示这3项，不显示其他如m2m # list_display_links = ("user","email",) # list_filter = ("user", "email","gender") # list_per_page = 3 # 每页显示数量 # list_max_show_all = 4 # 低于多少可以出现按钮显示所有 # list_editable = ("email","age","gender") # 除了list_display_links的列，因为需要点击，所以不能为input框 # search_fields = ("user","email","age","gender") # 模糊搜索 # date_hierarchy = "create" # 指向字段create # preserve_filters = False # 默认是True，保留筛选条件。 # save_as = True # save_as_continue = True # save_on_top = True # raw_id_fields = ("ug","m2m") # fields = ('user',"gender",) # exclude = ('user',) # readonly_fields = ('user',"gender") # fieldsets = ( # ('基本数据', { # 'fields': ('user', 'gender', 'email',) # }), # ('其他', { # 'classes': ('collapse', 'wide', 'extrapretty'), # 'collapse','wide', 'extrapretty' # 'fields': ('ug',"m2m"), # }), # ) # filter_vertical = ("m2m",) # 针对ManyToManyField字段 # filter_horizontal = ("m2m",) # 针对ManyToManyField字段 # ordering = ('-age',) # def get_ordering(self, request): # return ['-age', ] # 与ordering = ('-age',)的效果一致 # view_on_site = False # def view_on_site(self, obj): # return 'https://www.baidu.com' radio_fields = { "ug":admin.VERTICAL, # "ug":admin.HORIZONTAL, } admin.site.register(models.UserInfo,UserInfoAdmin)
25. show_full_result_count = True，列表时，模糊搜索后面显示的数据个数样式

26. formfield_overrides = {}，详细页面时，指定现实插件
没做出来
27. prepopulated_fields = {}，添加页面，当在某字段填入值后，自动会将值填充到指定字段。

28. form = ModelForm，用于定制用户请求时候表单验证
待补充，将另起一文章。
29. empty_value_display = "列数据为空时，显示默认值"
没做出来
30.其他
changelist_view
