这不是同名的另一个问题的副本。
我正在使用Rails 4.0和ruby 2.0.0与Ember（以及Ember数据）。
我的JSON以以下格式发布到OrdersController的create操作：
Parameters: {"order"=>{"status"=>"pending payment", "date"=>"5/11/2013", ... "user_id"=>11, "booking_id"=>8}}
其中...是JSON中发送的其他属性的截断。
我得到上面的错误：返回Fixnum（整数）而不是用户关联记录。我的订单型号：
class Order < ActiveRecord::Base
resourcify
belongs_to :user
belongs_to :booking, inverse_of: :orders
end
OrdersController的Rails 4强参数：
# Strong Parameters (Rails 4)
def order_params
params.require(:order).permit(:status, :date, ... :user_id, :booking_id)
end
其中...再次截断其他属性。
我知道由于类型不匹配而导致错误，但我无法弄清楚原因。我有其他模型使用相同的语法来构建记录关联，并且没有一个返回类型不匹配。
如果您需要，请在OrdersController上执行create操作：
# POST /orders
# POST /orders.json
def create
@order = Order.create(order_params)
if @order.new_record?
render json: { errors: @order.errors.messages }, status: 422
else
render json: @order, status: 201
end
end
请帮忙！
