您好，我刚刚收到以下错误：在"new"中：参数数目错误（给定7，应为0）（ArgumentError）
在 * 应用程序/服务/四分卫. rb * 中，我有：

class Quarterback
attr_accessor :id, :firstname, :secondname, :club, :position, :price, :totalpoints,
def initialize(id, firstname, secondname, club, position, price, totalpoints)
    @id = id
    @firstname = firstname
    @secondname = secondname
    @club = club
    @position = position
    @price = price
    @totalpoints = totalpoints
end

def info
    "#{firstname} works for #{club} and has a cost of #{price}."
end

sparky = Quarterback.new('1', 'John', 'Edgar', 'Liverpool', 'Forward', '100', '38' )
puts sparky.info
end

谢谢你的帮助!
