当前，当我尝试在valid?对象上调用headshot_image或Player时，测试失败。看完踪迹后，我不确定去哪儿了。谁能指出我可能做错了什么？我可以调用播放器对象上的任何属性，并且它会相应地做出反应，但是对于valid?和headshot_image来说，我得到了错误。
Player.rb
class Player < ApplicationRecord
mount_uploader :headshot_image, PlayerHeadshotUploader
end
PlayerHeadshotUploader
class PlayerHeadshotUploader < CarrierWave::Uploader::Base
include CarrierWave::RMagick
storage :file
def store_dir
"uploads/#{model.class.to_s.underscore}"
end
def default_url
"/uploads/player/no-profile-pic.jpg"
end
version :thumb do
process :resize_to_fit => [50, 50]
end
version :thumb do
process :resize_to_fit => [50, 50]
end
def extension_white_list
%w(jpg jpeg gif png)
end
def filename
"#{secure_token}.#{file.extension}" if original_filename
end
protected
def secure_token
var = :"@#{mounted_as}_secure_token"
model.instance_variable_get(var) or model.instance_variable_set(var, SecureRandom.uuid)
end
end
错误和跟踪

根据请求更新添加player_test.rb
require 'test_helper'
class PlayerTest < ActiveSupport::TestCase
setup do
@player = players(:one)
end
test "first_name is present" do
@player.first_name = nil
assert_not @player.save
end
end
