Django之Admin

二.定制Admin

在admin.py中只需要讲Mode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)

#admin.site.register(models.UserInfo,admin.ModelAdmin)  # 默认 admin.ModelAdmin

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：

方式一：

class UserAdimin(admin.ModelAdmin):
    
    def no_column(self,obj):

        return 'xxxxxx'
    
    list_display = ['name','email',no_column,'nickname']
    

   

admin.site.register(models.UserInfo,UserAdimin)


方式二：

@admin.register(models.UserInfo)
class UserAdimin(admin.ModelAdmin):
    
    def no_column(self,obj):

        return 'xxxxxx'
    
    list_display = ('name','email',no_column,'nickname')
    
    
    
#list_display = (,)或[ ]

1. list_display，列表时，定制显示的列。

2.list_display_links，列表时，定制列可以点击跳转。

class UserAdimin(admin.ModelAdmin):
    list_display = ('name','email',no_column)

    list_display_links = ('email',)   #逗号


    def no_column(self,obj):

        return 'xxxxxx'

admin.site.register(models.UserInfo,UserAdimin)

3. list_filter，列表时，定制右侧快速筛选。

class UserAdimin(admin.ModelAdmin):
    list_display = ('name','email',)

    list_filter = ('name','group')

 还可以：

from django.utils.translation import ugettext_lazy as _
class UserAdimin(admin.ModelAdmin):
    list_display = ('name','email',)

    class Ugg(admin.SimpleListFilter):
        title = _('萨达额')
        parameter_name = 'xxxx'

        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')
            # return models.UserGroup.filter(id__gt=10).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(group_id=v)

    list_filter = ('name',Ugg)

4. list_select_related，列表时，连表查询是否自动select_related

from django.utils.translation import ugettext_lazy as _
class UserAdimin(admin.ModelAdmin):
    list_display = ('name','email','group')

    class Ugg(admin.SimpleListFilter):
        title = _('萨达额')
        parameter_name = 'xxxx'

        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')
            # return models.UserGroup.filter(id__gt=10).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()
            if v:
                return queryset.filter(group_id=v)
            else:
                return request

    list_filter = ('group',Ugg)
    list_select_related = ('group',)

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

class UserAdimin(admin.ModelAdmin):
    list_display = ('name','email')

    list_editable = ('email',)

7. search_fields，列表时，模糊搜索的功能

class UserAdimin(admin.ModelAdmin):
    list_display = ('name','email')


    search_fields = ('name','email')

8. date_hierarchy，列表时，对Date和DateTime类型进行搜索

class UserAdimin(admin.ModelAdmin):
    list_display = ('name','email','ctime')

    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 效果不一样
    extra = 0
    model = models.UserInfo


class UserGroupAdmin(admin.ModelAdmin):
    list_display = ('title',)
    inlines = [UserInfoInline, ]

admin.site.register(models.UserGroup,UserGroupAdmin)

14. action，列表时，定制action中的操作

class UserAdimin(admin.ModelAdmin):
    list_display = ('name','email','ctime')


    def func(self, request, queryset):
        # print(self, request, queryset)
        print(request.POST.getlist('_selected_action'))
        print('代码来了。。。。')

    func.short_description = "中文显示自定义Actions"
    actions = [func, ]

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

# change_list_template = ['list.html']
