如何在同一索引页的单独表格中显示真/假布尔值？

问题描述

我可以检查_form中的布尔值，但是目标仅显示在已完成的目标表中，而不显示在上方的目标表中（无论是否已检查） 。

如何在顶部表格中显示虚假目标（未完成的目标）以及底部表格中的真正目标（已完成检查的目标）？

很抱歉代码炸弹丢失，我是布尔&因此我想确保显示了可能对解决此问题有用的所有代码，因为我随机扔了一些我认为可能有用的东西。

解决方案

在您的模型中创建一个未完成的范围，如

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

然后在控制器上执行

  class GoalsController< ApplicationController 
 def index 
 @accomplished_goals = current_user.goals.accomplished 
 @unaccomplished_goals = current_user.goals.unaccomplished 
 end 
 end 
 
<表> 
<％@ done_goals.each do |已完成| ％GT; 
 .... 
<％end％> 
< / table> 
 
< table> 
<％@ unaccomplished_goals.each do | unaccomplished | ％GT; 
 .... 
<％end％> 
< / table> 
  
 
I'm able to check off the Boolean in the _form, but then the "goal" only shows in the "accomplished" goals table and not in the goals table above it (regardless of if it is checked off or not).
How can I show false goals (those goals not checked off as completed) in the top table and true goals (those checked off as completed) in the bottom table?
Sorry for the code bomb drop, I'm new to Boolean & scopes so I wanted to make sure I showed all the code that might be useful to solving this problem because I threw in random stuff I thought might work.

 解决方案 
in your model create a  unaccomplished scope like 
scope :unaccomplished, -> { where(accomplished: false) }
then on the controller you can do 
class GoalsController < ApplicationController
  def index
    @accomplished_goals = current_user.goals.accomplished
    @unaccomplished_goals = current_user.goals.unaccomplished
  end
end
now finally on the index page you can do 
<table>
    <% @accomplished_goals.each do |accomplished| %>
      ....
    <% end %>
</table>

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