如何修复Sinatra在/未定义的本地变量或方法上返回NameError的问题

问题描述 投票:0回答:1

我正在尝试将我创建的RPG字符表转换为网页,但是遇到麻烦。

这是cardtricks.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:

  $file_id = Character.new(@playername, @playermajor, @playerpentas, @playerwands, @playerswords, @playercups, @playereyes, @playerdress, @playerhands)
  puts "Meet your new character!"
  $file_id.display
  mainmenu
end
puts wizard_wizard

我从Sinatra得到的错误是:

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

我曾尝试提供wizard_wizard范围(@$),但这只会导致更多语法错误。

wizard_wizard未定义。

首先使用sinatra,一个红宝石过程开始,它将加载一般的东西,并且在您的情况下,还定义了Character类。但是执行流程从您定义调用/时应该发生的事情开始:调用wizard_wizard,将键:wizard_wizard赋予locals哈希,然后调用erb解释索引模板。只有这样,才能解析wizard_wizard函数。

在一个单独的文件中定义您的功能,需要时需要该文件。另外,要求终端输入sinatra网站模板吗?那行不通。您不需要在这里使用sinatra-有了它,您似乎必须构建根本不需要框架的终端应用程序,而必须适应Web应用程序的工作方式(HTML,通过表单输入,Javascript)。
