覆盖django管理员ListFilter模板

Question

我想覆盖默认的django管理过滤器模板,使用我自己的模板:

https://github.com/feincms/feincms/blob/master/feincms/templates/admin/filter.html

我SimpleListFilter通过继承来编写自己的类django.contrib.admin.SimpleListFilter

class PublisherStateFilter(admin.SimpleListFilter):
    title = _('Status')
    parameter_name = 'status'
    template = 'admin/blogitty/filter.html'

    [...]

这非常有效.

但是我想对所有管理过滤器使用相同的模板.有没有办法覆盖给定应用程序的所有过滤器模板,而无需ListFilter为每个ForeignKey和ManyToMany关系定义自定义.

我的项目是blogitty.我尝试了模板DIR的两个选项:

blogitty/templates/admin/filter.html

和:

blogitty/templates/admin/blogitty/filter.html

没运气 :-(

浏览源代码:

https://github.com/django/django/blob/master/django/contrib/admin/options.py#L1030

    return TemplateResponse(request, form_template or [
        "admin/%s/%s/change_form.html" % (app_label, opts.model_name),
        "admin/%s/change_form.html" % app_label,
        "admin/change_form.html"
    ], context)

https://github.com/django/django/blob/master/django/contrib/admin/options.py#L1569

    return TemplateResponse(request, self.change_list_template or [
        'admin/%s/%s/change_list.html' % (app_label, opts.model_name),
        'admin/%s/change_list.html' % app_label,
        'admin/change_list.html'
    ], context)

据我了解.Django ModelAdmin检查多个路径以呈现给定模型的changeform或changelist.但是,对于a ListFilter,不会进行额外的检查以加载自定义模板.

https://github.com/django/django/blob/master/django/contrib/admin/filters.py#L60

class ListFilter(object):
    title = None  
    template = 'admin/filter.html'

更新 - TEMPLATE_DIRS设置:

BASE_DIR = dirname(dirname(__file__))    

TEMPLATE_DIRS = (
    join(BASE_DIR, 'templates'),
)

这可能有帮助

class ClassFilter1(admin.ModelAdmin):
    title = 'Filter Class'
    parameter_name = 'filter-class'

    def lookups(self, request, model_admin):
       # Your Lookups

    def queryset(self, request, queryset):
       # Your Lookups

class FilterClass(admin.ModelAdmin):
    list_filter = (ClassFilter1, ClassFilter2)
    change_list_template = 'polls/change_list_template.html'

并覆盖change_list_template.html并将 .html 放入polls/templates/polls
