Ruby Enumerable Collect Array仍显示在列表末尾 [英] Ruby Enumerable Collect Array still showing at end of list

问题描述

我正在使用Ruby枚举来创建另一个模型的数组。 参加会议方法

I'm using Ruby enumerable to create an array of from another model. The method "companiesattending"

class Conference < ActiveRecord::Base
  has_many :accountconferences
  has_many :accounts, :through => :accountconferences
  accepts_nested_attributes_for :accounts

  def companiesattending
    accounts.collect {|f| f.name }
  end

end

奇怪的是当我将其放入视图时，我得到了预期的项目列表，然后列表末尾的数组的某些成员仍在数组中：

What's strange is when I put this into a view I get a list of items as expected and then some of of the members of the array at the end of the list still in an array:

查看结果

    <ul style="list-style-type: none;">
        <li>Company 1</li>
    </ul>

    <ul style="list-style-type: none;">
        <li>Company 2</li>
    </ul>
[&quot;3point5.com&quot;, &quot;Company&quot;, &quot;5.1&quot;, &quot;A O Coolers&quot;, &quot;Abo Gear&quot;, &quot;Access Fund&quot;, &quot;AceCamp.com&quot;, &quot;ACORN&quot;

/app/views/conferences/_accounts.html.erb

/app/views/conferences/_accounts.html.erb

<div class="span5">
<h3 class="pull-left">Companies That Are Attending</h3></br></br></br>
 <%= @accounts.each do |f|%>
    <ul style="list-style-type: none;">
        <li><%= f %></li>
    </ul>
 <% end %>
</div>

/app/models/conferences.rb（显示操作）

/app/models/conferences.rb (Show Action)

  def show
    @conference = Conference.find(params[:id])
    @accounts = @conference.companiesattending  
  end

我想念什么？

推荐答案

而不是：

<%= @accounts.each do |f|%>

在不使用 = 的情况下使用此功能：

Use this without =:

<% @accounts.each do |f|%>

= 是代码显示的原因数组。

= is the reason your code is displaying the array.
