Question

有没有办法在admin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＆＃39; isClosed＆＃39;的默认值领域不是＆＃39;不是＆＃39;所有＆＃39;。

感谢。

您需要创建自定义列表过滤器，继承自django.contrib.admin.filters.SimpleListFilter并默认过滤未结算的帐户。这些方面应该有用：

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, request, 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]
