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', 'yearMonth', 'month', 'warehouse',) wagtail怎么将右侧过滤器的yearMonth字段更改为日期选择器？可以任意的选择年份和月份？

你可以使用 Django 的 DateField 和 DateHierarchyFilter 来实现这个功能。首先，你需要在模型中将 yearMonth 字段更改为 DateField 类型：

class WarehousePeople(models.Model):
    name = models.CharField(max_length=100)
    yearMonth = models.DateField()
    month = models.CharField(max_length=10)
    warehouse = models.CharField(max_length=100)
    subjectMatter = models.CharField(max_length=100)

    def __str__(self):
        return self.name

接下来，在 ModelAdmin 中使用 DateHierarchyFilter 和 DateFieldListFilter 类来更改过滤器：

from django.contrib.admin import DateFieldListFilter, DateHierarchyFilter

class WarehousePeopleAdmin(ModelAdmin):
    model = WarehousePeople
    menu_label = '库房人员出入库信息'
    menu_icon = 'site'
    list_display = ['name', 'yearMonth', 'month', 'warehouse', 'subjectMatter']
    list_filter = (
        ('yearMonth', DateHierarchyFilter),
        ('name',),
        ('warehouse',),
    )
    date_hierarchy = 'yearMonth'
    date_hierarchy_drilldown_urls = {}

    def changelist_view(self, request, extra_context=None):
        self.date_hierarchy_drilldown_urls = {}
        return super().changelist_view(request, extra_context)

    def get_list_filter(self, request):
        """
        Return the list of filters that should be used in the admin
        list view.
        """
        list_filter = super().get_list_filter(request)
        for filter_spec in list_filter:
            if isinstance(filter_spec, tuple):
                field_name = filter_spec[0]
            else:
                field_name = filter_spec
            try:
                field = self.opts.get_field(field_name)
            except FieldDoesNotExist:
                continue
            if isinstance(field, models.DateField):
                cls = DateFieldListFilter
                if field_name == 'yearMonth':
                    cls = lambda f, request: DateHierarchyFilter(f, request, field_name='yearMonth')
                filter_spec = (filter_spec[0], cls)
                if field_name == self.date_hierarchy:
                    self.date_hierarchy_drilldown_urls = {
                        'day': reverse('admin:%s_%s_day' % self.get_model_info(), args=['year', 'month', 'day']),
                        'month': reverse('admin:%s_%s_month' % self.get_model_info(), args=['year', 'month']),
                        'year': reverse('admin:%s_%s_year' % self.get_model_info(), args=['year']),
                    }
                yield filter_spec
            else:
                yield filter_spec

这段代码中，我们将 yearMonth 字段的过滤器更改为 DateHierarchyFilter 类，这样就可以使用日期选择器来选择年份和月份了。同时，我们还需要重载 get_list_filter 和 changelist_view 方法来支持日期选择器。
