如何在同一索引页的不同表中显示 True/False 布尔值？

Question

我可以检查 _form 中的布尔值，但是 "goal" 只显示在 "accomplished" 目标 table 而不是目标 table 在它上面（不管它是否被勾选）。

如何在顶部 table 显示虚假目标（未勾选完成的目标），在底部 table 显示真实目标（已完成勾选的目标）？

对于代码炸弹投掷表示抱歉，我是布尔值和作用域的新手，所以我想确保我展示了所有可能对解决此问题有用的代码，因为我随机添加了我认为可能有用的东西。

index.html.erb

<!-- Default bootstrap panel contents -->
<div id="values" class="panel panel-default">

  <!-- Table -->
  <table>
    <% @goals.each do |goal| %>
      <% if goal.user == current_user %>
      <% if goal.accomplished = false %>
      <tr>
        <td class="value">
        <%= link_to edit_goal_path(goal) do %>

        <% end %></td>

Answer 1

在您的模型中创建一个未完成的范围，例如

scope :unaccomplished, -> { where(accomplished: false) }

然后在控制器上你可以做

class GoalsController < ApplicationController
  def index
    @accomplished_goals = current_user.goals.accomplished
    @unaccomplished_goals = current_user.goals.unaccomplished
  end
end

现在终于可以在索引页上做

<table>
    <% @accomplished_goals.each do |accomplished| %>
      ....
    <% end %>
</table>

<table>
    <% @unaccomplished_goals.each do |unaccomplished| %>
        ....
    <% end %>
</table>
