Default filter in Django admin13个

有没有办法在管理员中设置过滤器的默认值

现场？

Class Account(models.model): 
    isClosed = models.BooleanField(blank=True) 
    name = models.CharField(core=True,max_length=255,unique=True)

在admin.py中：

class Admin(admin.ModelAdmin): 
     list_filter = ['isClosed']

在管理页面上,我想要’isClosed’字段的默认值
是’不’,不是’全’.

谢谢.

解决方法

您需要创建一个自定义列表过滤器,继承自django.contrib.admin.filters.SimpleListFilter并默认过滤未关闭的帐户.这些方面的东西应该有效：

from datetime import date

from django.utils.translation import ugettext_lazy as _
from django.contrib.admin import SimpleListFilter


class IsClosedFilter(SimpleListFilter):
    title = _('Closed')

    parameter_name = 'closed'

    def lookups(self,request,model_admin):
        return (
            (None,_('No')),('yes',_('Yes')),('all',_('All')),)

    def choices(self,cl):
        for lookup,title in self.lookup_choices:
            yield {
                'selected': self.value() == lookup,'query_string': cl.get_query_string({
                    self.parameter_name: lookup,},[]),'display': title,}

    def queryset(self,queryset):
        if self.value() == 'closed':
            return queryset.filter(isClosed=True)
        elif self.value() is None:
            return queryset.filter(isClosed=False)


class Admin(admin.ModelAdmin):
    list_filter = [isClosedFilter]
