你通过自定义`list_filter`来实现这个功能。具体步骤如下：

1. 定义一个自定义的Filter类，继承`django.contrib.admin.SimpleListFilter`类，重写`queryset`和`lookups`方法，来实现筛选功能。

import datetime

class YearMonthFilter(admin.SimpleListFilter):
    title = 'Year Month'
    parameter_name = 'year_month'

    def lookups(self, request, model_admin):
        # 获取所有可以选择的年月列表
        year_month_list = []
        for obj in model_admin.model.objects.all():
            year_month = obj.yearMonth.strftime('%Y-%m')
            if year_month not in year_month_list:
                year_month_list.append(year_month)

        return [(ym, ym) for ym in year_month_list]

    def queryset(self, request, queryset):
        if self.value():
            year_month = datetime.datetime.strptime(self.value(), '%Y-%m')
            return queryset.filter(yearMonth=year_month)

2. 在`list_filter`中添加自定义的Filter类

class warehousePeopleBase(ModelAdmin):
    model = warehousePeople
    menu_label = '库房人员出入库信息'  # ditch this to use verbose_name_plural from model
    menu_icon = 'site'  # change as required
    list_display = ['name', 'yearMonth', 'month', 'warehouse', 'subjectMatter']
    list_filter = ('name', 'warehouse', YearMonthFilter)

这样就可以在右侧过滤器中选择任意年份和月份进行筛选了。
