我正在使用 Rails 3.2.14、inherited_resource 和 strong_parameter gem。
已注释掉
#config.active_record.whitelist_attributes = false. in production.rb
#config.active_record.mass_assignment_sanitizer = :strict in developemt.rb
将此添加到初始化程序
ActiveRecord::Base.send(:include, ActiveModel::ForbiddenAttributesProtection)
但是不断收到这个巨大的分配错误，其中名称未能分配给模型并导致 generate_slug 函数失败：
