Question

undefined method name for #<StockQuote::NoDataForStockError:0x007fea46e5fd70>

我正在使用此处的'stock_quote'宝石来获取有关各种股票的数据https://github.com/tyrauber/stock_quote

我有时在刷新浏览器时会出现错误，但有时候应用程序运行正常而我没有更改任何代码。我认为主要问题是错误的请求错误，但我不知道该怎么做。我是编程新手，所以我不确定解决错误需要哪一个，所以我只提供了所有这些。就像我说的那样，错误有时只会出现，这非常令人沮丧。希望有人可以帮助我，谢谢！

以下是我的浏览器中显示的错误页面：

Showing /Users/frank/Desktop/projects/final-investing/app/views/stock/index.html.erb where line #37 raised:

undefined method 'name' for #<StockQuote::NoDataForStockError:0x007fea433235e0>

Extracted source (around line #9):

7. def self.new_stock_lookup(ticker)

8. looked_up_stock = StockQuote::Stock.quote(ticker)

9.     return nil unless looked_up_stock.name

10.    

11. new_stock = new(ticker:looked_up_stock.symbol,

12. name:looked_up_stock.name,

以下是控制台错误：

这是我的股票模型

class Stock < ApplicationRecord

def self.new_stock_lookup(ticker)
    looked_up_stock = StockQuote::Stock.quote(ticker)
    return nil unless looked_up_stock.name

new_stock = new(ticker:looked_up_stock.symbol,
                  name:looked_up_stock.name,
         current_price:looked_up_stock.last_trade_price_only,
     one_year_estimate:looked_up_stock.oneyr_target_price,
        percent_change: (looked_up_stock.oneyr_target_price -
looked_up_stock.last_trade_price_only) / looked_up_stock.last_trade_price_only)
    new_stock
  end

错误请求错误
