傳遞一個有效的屬性控制器，但驗證失敗

Question

型號：

module V1 
    class Player < ActiveRecord::Base 

    validates :name, presence: true 
    validates :default_pull_rate, numericality: true, allow_nil: false 

    has_many :player_links 

    end 

end 

規格（我甚至嘗試明確設置default_pull_rate直列如下圖）：

it "creates a new player" do 

    expect { post :create, format: :json, player: FactoryGirl.attributes_for(:player, default_pull_rate: 5) }.to change(V1::Player, :count).by(1) 
end 

廠：

FactoryGirl.define do 
    factory :player, class: V1::Player do 
    name "Frank" 
    default_pull_rate 100 
    end 

控制器：

.... 
def create 
    @player = Player.new(player_params) 

    if @player.save! 
    redirect_to @player 
    end 
end 

private 

def player_params 
    params.require(:player).permit(:name, :default_pull_rated) 
end 

錯誤消息：

ActiveRecord::RecordInvalid: Validation failed: Default pull rate is not a number 

傳遞模型規格：在player_params

it "is invalid without a default_pull_rate" do 
    expect(FactoryGirl.build(:player, default_pull_rate: nil)).to_not be_valid 
end 

it "is invalid when default_pull_rate is a string" do 
    expect(FactoryGirl.build(:player, default_pull_rate: "fast")).to_not be_valid 
end

錯字？

def player_params 
    params.require(:player).permit(:name, :default_pull_rated) 
end 

應_rate不_rated

def player_params 
    params.require(:player).permit(:name, :default_pull_rate) 
end
