如何在同一索引页上的单独表中显示真/假布尔值？

我能够在_form中检查布尔值，但是“目标”只显示在“已完成”目标表中，而不是在其上方的目标表中（无论是否已检查）。

如何在顶部表格中显示虚假目标（未完成核对的目标）和底部表格中的真实目标（已完成核对的目标）？

对于代码炸弹丢弃感到抱歉，我是布尔和范围的新手，所以我想确保我展示了解决这个问题可能有用的所有代码，因为我投入了我认为可能有用的随机内容。

index.html.erb

 
 
GOALS
   
 
  <span class="glyphicon glyphicon-plus"  
  
 
ACCOMPLISHED
    

goal.rb

 class Goal  { where(accomplished: true) } end 

create_goals.rb

 class CreateGoals < ActiveRecord::Migration def change create_table :goals do |t| t.string :name t.date :deadline t.boolean :accomplished t.timestamps null: false end end end 

schema.rb（部分）

  create_table "goals", force: true do |t| t.string "name" t.date "deadline" t.boolean "accomplished", default: false t.datetime "created_at", null: false t.datetime "updated_at", null: false t.integer "user_id" end add_index "goals", ["deadline"], name: "index_goals_on_deadline" add_index "goals", ["user_id"], name: "index_goals_on_user_id" 

_form.html.erb

   
 
 prohibited this goal from being saved:
 
  
  
 
  
 
 
  
 
  Deadline:   [:month, :day, :year], class: 'date-select' %>

在你的模型中创建一个未完成的范围，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面上做了

  <% @accomplished_goals.each do |accomplished| %> .... <% end %>   <% @unaccomplished_goals.each do |unaccomplished| %> .... <% end %>
