如何从后端的 class 中的前端访问 params[:name]

Question

如何访问我的 session[:name]，它位于我的 Sinatra 应用程序的前端，在我后端的 class 中？我想这样做，这样我就可以将我所有的消息（人们说的）存储在 class 中，以便能够快速更改我的后端消息，这样我就可以在需要时更改它，而不必通过整个前端在那里编码。

这是前端部分：

post '/startgames' do

  play = params[:playgame]
  session[:name] = params[:name]
  session[:age] = params[:age].to_i

  if play == "Joe's Trippy Adventure Game" && session[:age] > 17 
    erb :trippygame1, :locals => {:message1 => "Great #{session[:name]} you are old enough to Play Joe's Trippy Adventure Game.",
                      :message2 => "One day #{session[:name]} is sitting around Smoking a bong when someone knocks on the door.", 
                      :message3 => "Do you get up and answer it?"}
  elsif play == "Joe's Trippy Adventure Game" && session[:age] < 17 
    erb     erb :safari1, :locals => {:message1 => "#{session[:name]} You are to young to play Joe's Trippy game how about a nice Lepoard adventure game?", :age => ""}
  elsif play == "Jade's Safari Adventure Game" && session[:age] < 17
    erb :safari1, :locals => {:message1 => "#{session[:name]} Chose to play Jade's Safari Adventure Game.", :age =>""}
  else play == "Jade's Safari Adventure Game" && session[:age] > 17
    erb :safari1, :locals => {:age => "Hey man Aren't You a little old to play this type of game?",
                  :message1 => "#{session[:name]} Chose to play Jade's Safari Adventure Game."}
  end
end

这是后端部分：

class Start_messages


  def welcome
    "Welcome To Joe's Games."
    end

  def name_age
    "Enter your name & age to start."
    end

  def to_start_jade
    "So you wanna play Jade's Safari Adventure game ?"
  end


  def to_start_joe
    "If you want to play Joe's Trippy Adventure Game"
  end

  def start_joe
      "Great #{session[:name]} you are old enough to Play Joe's Trippy Adventure Game."
  end

end

我真的希望能够将所有消息保存在 class 中而不是在前端进行硬编码。另外，在后端测试它们对我来说会更容易，因为我还没有开始测试前端的东西……我正在学习 TDD，所以测试测试测试 :)

谢谢 Dave 你的建议让我走上了正确的方向。这就是我所做的，以防它会帮助别人。这部分用于后端

def start_joe(name)
    "Great #{name} you are old enough to Play Joe's Trippy Adventure Game."
end

def start_jade(name)
    "#{name} Chose to play Jade's Safari Adventure Game."
end

def too_young(name)
    "#{name} You are too young to play Joe's Trippy game how about a nice Lepoard adventure game?"
end

def too_old(name)
    "Hey #{name} Aren't You a little old to play this type of game?"
end

对于前端。

 post '/startgames' do

play = params[:playgame]
session[:name] = params[:name]
session[:age] = params[:age].to_i
name = session[:name]
if play == "Joe's Trippy Adventure Game" && session[:age] > 17 
        erb :trippygame1, :locals => {:message1 => message.start_joe(name),
                                      :message2 => "One day #{session[:name]} is sitting around Smoking a bong when someone knocks on the door.", 
                                      :message3 => "Do you get up and answer it?"}
elsif play == "Joe's Trippy Adventure Game" && session[:age] < 17 
        erb     erb :safari1, :locals => {:message1 => message.too_young(name) , :age => ""}
elsif play == "Jade's Safari Adventure Game" && session[:age] < 17
        erb :safari1, :locals => {:message1 => message.start_jade(name), :age =>""}
else play == "Jade's Safari Adventure Game" && session[:age] > 17
        erb :safari1, :locals => {:age => message.too_old(name),
                                  :message1 => message.start_jade(name)}
   end
end

工作仍在进行中，但感谢您的建议，现在完全有道理我不知道为什么我没有想到这个
