推荐答案
如果您只是这样做,会遇到问题吗?
if you just do simply this, do you get a problem?
# ability.db
def initialize(user)
case
# ...
when user.super_admin?
can :manage, :all
when user.admin?
can :manage, Profile, :institution_id => user.institution.id
#
# ...
end
这将允许: Profile.accessible_by(current_user)
,此处与 current_user.profiles
class AdminUser
has_one :institution
has_many :profiles, :through => :institution
end
ActiveAdmin.register Profile do
scope_to :current_user #here comes the variable which set in initializer
end
如果您希望超级管理员访问所有帖子,则可以使用:association_method选项
if you want superadmin to access all posts, you can use the :association_method option
ActiveAdmin.register Profile do
scope_to :current_user, :association_method => :admin_profiles
end
# in class User
def admin_profiles
if super_admin?
Profile.unscoped
else
profiles
end
end
一个棘手的解决方案可以对此进行概括,并使用委托者类作为代理来取消超级管理员所有模型的范围。我可以根据要求拼出。
A tricky solution could generalize this and use a delegator class as proxy to unscope all models for superadmins. i can spell out on request.
