请提供此Beta代码帮助，如何解决？

本文介绍了请提供此Beta代码帮助，如何解决？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

可能重复：

我有代码：

def check_beta_code beta_code_array = ['AAAAAAAAAA', 'BBBBBBBBBB', 'CCCCCCCCCC', 'DDDDDDDDDD', 'EEEEEEEEEE'] beta_code_array.each do |code| if :beta_code != code errors.add(:beta_code, "Invalid Beta Code") end end end

此代码的问题是，即使有人输入了正确的密码，仍然会产生4个错误，因为另外4个错误。

The problem with this code is that even if someone inputs a correct password, 4 errors are still generated because the other 4 aren't correct.

推荐答案

我假设这段代码在某个地方的模型中。您可以尝试创建一个包含beta代码的模型，并将某些值存储在数据库中。然后只需要查询数据库中的代码并查看是否存在匹配项即可。

I'm assuming this code is in a model somewhere. You can try creating a model that holds the beta codes and store some values in the DB. Then it's just a matter of querying the db for the code and seeing if there's a match:

# model class BetaCode < ActiveRecord::Base # assumes a field named 'code' end # add some codes (via migration, console, manually, etc) ['AAAAAAAAAA', 'BBBBBBBBBB', 'CCCCCCCCCC', 'DDDDDDDDDD', 'EEEEEEEEEE'].each do |code| BetaCode.create(:code => code ) end # and check for a match when user submits code (controller) @code = BetaCode.find_by_code(user_code) if @code.present? # user is approved else # sorry, no luck end

如果要使用代码段，则始终可以使用 member？方法创建数组。

If you want to use your snippet, you can always use the member? method for an array.
