多对多关系管理员上的 Django 额外字段以相反的顺序添加

Question

带有额外字段的多对多关系的默认管理界面如下图所示

是否可以定义此列表中的项目以相反的顺序显示，以便新字段始终保持在顶部第一行？

Answer 1

在 django/contrib/admin/options.py 中

大约 265 的行号： 找到这个方法：

def formfield_for_manytomany(self, db_field, request=None, **kwargs):
    """
    Get a form Field for a ManyToManyField.
    """
    # If it uses an intermediary model that isn't auto created, don't show
    # a field in admin.
    if not db_field.rel.through._meta.auto_created:
        return None
    db = kwargs.get('using')

    if db_field.name in self.raw_id_fields:
        kwargs['widget'] = widgets.ManyToManyRawIdWidget(db_field.rel,
                                self.admin_site, using=db)
        kwargs['help_text'] = ''
    elif db_field.name in (list(self.filter_vertical) + list(self.filter_horizontal)):
        kwargs['widget'] = widgets.FilteredSelectMultiple(db_field.verbose_name, (db_field.name in self.filter_vertical))

    if 'queryset' not in kwargs:
        queryset = self.get_field_queryset(db, db_field, request)
        if queryset is not None:
            kwargs['queryset'] = queryset

    return db_field.formfield(**kwargs)

尝试操作/重新排序返回值或尝试查看 **kwargs 值
