有没有办法在管理站点中设置过滤器的默认值?

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,我希望“isClosed”字段的默认值为“否”,而不是“全部”。

谢谢。

您需要创建一个自定义列表过滤器,django.contrib.admin.filters.SimpleListFilter默认情况下从未关闭的帐户继承和过滤。这些方面的东西应该起作用:

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]
