Answer 1

这样做会覆盖数据库排序:

@item.children.except(:order).order("your_sort_column")

例子:

organization.self_and_descendants.to_sql
=> "SELECT `organizations`.* FROM `organizations`  WHERE (`organizations`.`lft` >= 1 AND `organizations`.`lft` < 54) ORDER BY `organizations`.`lft`" 

organization.self_and_descendants.except(:order).order("organization_nm").to_sql
=> "SELECT `organizations`.* FROM `organizations`  WHERE (`organizations`.`lft` >= 1 AND `organizations`.`lft` < 54) ORDER BY organization_nm"
