Ruby 如何修复Sinatra在/未定义的局部变量或方法处返回NameError

我正在尝试将我创建的RPG字符表转换为网页，但遇到了问题

这是cardticks.rb文件：

require 'sinatra'
class Character
    def initialize(name, major_arcana, pentacles, wands, swords, cups, eyes, dress, hands)
        @name = name
        @major_arcana = major_arcana
        @pentacles = pentacles
        @wands = wands
        @swords = swords
        @cups = cups
        @eyes = eyes
        @dress = dress
        @hands = hands
    end
end

get '/' do
    erb :index, locals: {wizard_wizard: wizard_wizard}
end

这是.erb文件：

开始！

我从Sinatra那里得到的错误是：

undefined local variable or method `wizard_wizard' for #<Sinatra::Application:0x00007f6508de1470>

未定义的局部变量或方法“wizard\u wizard”#

---

我尝试给

向导\u向导
范围（
@
或
$
），但这只会导致更多语法错误
 
向导\u向导
未定义

使用sinatra，首先启动一个ruby进程，它将加载一般内容，在您的情况下还将定义Character类。但是，执行流从您定义调用
/
时应该发生的事情开始：调用
向导向导
，用键
：向导
将其交给
本地
散列，然后调用
erb
来解释索引模板。只有这样才能解析
wizard\u wizard
函数

在单独的文件中定义函数，需要时需要该文件。此外，在sinatra网站模板中请求终端输入？那不行。这里您不需要sinatra—有了它，您必须适应web应用程序的工作方式（HTML、通过表单输入、Javascript），同时您似乎想要构建一个终端应用程序，它根本不需要框架。
仅供参考，在视图文件中这样放置方法是非常不标准的。我将通过重构这一点来使用帮助器，也可以看到另一个次要的东西，您应该考虑使用关键字参数而不是位置代码，用于<代码>字符>初始化/<代码>方法。跟踪如此多的位置参数可能是一件很麻烦的事情！作为补充参考，语法在SO中很重要。可以将该站点视为一系列百科全书条目，其中包含解决该问题的答案。因此，清晰简洁的提问非常重要。全世界的人都会用这些问题来解决他们的问题，所以花时间写清楚对每个人都有帮助。
