Question

我正在尝试学习如何使用emberjs作为rails api的客户端！

我的代码位于此处：https://github.com/brunoocasali/ember-n-rails

是一个简单的rails-api，它通过restful端点提供CRUD操作。我正在关注this tutorial，但当我尝试在博文中保存评论时，我收到了Unpermitted params: :post。

我该如何解决这个问题？

Unpermitted params: :post

查看此错误，您似乎需要在post内的强参数定义中允许comments_controller.rb。所以，试试这个：

  private

  def comment_params
    params.require(:comment).permit(:author, :body, :post)
  end

使用EmberJS时未允许的参数
