如何将我的布尔输出更改为ruby中的字符串值

I have a form where my user enters a person in reply to a wedding invite. They enter a name, menu choice, and select: attending - Yes / No - I then have a count on the true and false amounts with labels so the user can see how many people are attending or not attending.

我有一个表格，我的用户输入一个人回复婚礼邀请。他们输入一个名称，菜单选项，然后选择：出席 - 是/否 - 然后我会用标签计算真假数量，这样用户就可以看到有多少人参加或不参加。

My problem is in the table itself. Where the RSVP column sits, i have at moment just got 'true' or 'false'. Is there anyway in Ruby i can change this to be a string value for my index.html.erb?

我的问题出在桌子本身。在RSVP列所在的位置，我现在得到'真'或'假'。无论如何在Ruby中我可以将其更改为index.html.erb的字符串值吗？

Index

指数

<% @replies.each do |reply| %>
  <tr>
    <td><%= reply.name %></td>
    <td><%= reply.menu %></td>
    <td><%= reply.rsvp %></td>
    <td><%= link_to 'Show', reply, class: "btn" %></td>
    <td><%= link_to 'Edit', edit_reply_path(reply), class: "btn" %></td>
    <td><%= link_to 'Delete', reply, method: :delete, data: { confirm: 'Are you sure?' }, class: "btn btn-danger" %></td>
    <td><%= reply.user.full_name %></td>
  </tr>
<% end %>

reply.rb

reply.rb

class Reply < ActiveRecord::Base
  attr_accessible :menu, :name, :rsvp, :user_id
  belongs_to :user

  def self.find_attending
    Reply.where(:rsvp => "true").count
  end

  def self.find_not_attending
    Reply.where(:rsvp => "false").count
  end
end

_form.html.erb

_form.html.erb

<%= f.input :user_id, collection: User.all, label_method: :full_name, :label => 'Added By' %>
<%= f.input :name, :label => 'Person(s) Name' %>
<%= f.input :menu, :label => 'Menu Choice' %>
<%= f.collection_radio_buttons :rsvp, [[true, 'Attending'] ,[false, 'Not Attending']], :first, :last %>

D b

class CreateReplies < ActiveRecord::Migration
  def change
    create_table :replies do |t|
      t.string :name
      t.text :menu
      t.boolean :rsvp, :default => false

      t.timestamps
    end
  end
end

I'm very new to Ruby, any pointers would be appreciated. Many thanks.

我是Ruby的新手，任何指针都会受到赞赏。非常感谢。

2 个解决方案

#1

Just use a ternary:

只需使用三元：

reply.rsvp ? "true" : "false"

Replace "true" and "false" by whatever strings you want to display.

用你想要显示的任何字符串替换“true”和“false”。

#2

How about "#{reply.rsvp}"? Seems to be cleaner, doesn't it?

“＃{reply.rsvp}”怎么样？似乎更干净，不是吗？
