ruby-on-rails – accept_nested_attributes_for：allow_destroy

简单形式,茧

我无法销毁嵌套属性的记录.基于一些冗长的研究,我相信我的代码是正确的,但我可能会遗漏一些愚蠢的东西.

模型

has_many :staff_services_joins,:dependent => :destroy
has_many :services,:through => :staff_services_joins
accepts_nested_attributes_for :staff_services_joins,:allow_destroy => true

这有点不正统,但我在连接模型上有两个组件,它们不是外键,需要设置.这就是为什么我接受连接模型的嵌套属性而不是服务模型.

控制器方法

def update
ap staff_params
# if @staff_member.update_with_account staff_params,params[:password]
if @staff_member.update_attributes staff_params
  flash[:notice] = 'Successfully updated staff member! :)'
  redirect_to vendor_store_staff_path current_store,@staff_member
else
  flash[:error] = 'Failed to update staff member :('
  render :edit
end end

参数很强

params.require(:staff).permit(
    :user_id,:store_id,:avatar,:remote_avatar_url,:first_name,:last_name,:email,:active,:admin,:staff_services_joins_attributes => [
        :staff_id,:service_id,:price,:duration,:_destroy
    ]
)

示例更新参数hash

{
"store_id" => "2","avatar" => "avatar.png","remote_avatar_url" => "","first_name" => "Joshua","last_name" => "Tyree","email" => "joshuat@createthebridge.com","active" => "0","admin" => "1","staff_services_joins_attributes" => {
    "0" => {
        "service_id" => "2","price" => "50.00","duration" => "30","_destroy" => "1"
    }
}

}

基于has,这个东西应该是破坏那个模型,但由于某种原因它肯定不是.绝对赞赏任何帮助.
