RecordNotFound:找不到带有“id"的关卡 [英] RecordNotFound: Couldn't find Level with "id"

问题描述

在修复此错误时遇到一些问题:

Having some trouble fixing this error:

 ActiveRecord::RecordNotFound (Couldn't find Level with 'id'=1 [WHERE "levels"."habit_id" = ?]):
  app/controllers/days_missed_controller.rb:9:in `create'

点击此按钮时:

<%= link_to '<span class="glyphicon glyphicon-remove"></span>'.html_safe, habit_level_days_missed_index_path({ habit_id: habit, level_id: habit.current_level }), remote: true, method: 'post', class: 'habit-check' %>    #    habits/_habit.html.erb, which is rendered by <%= render @habits %> in pages/home.html.erb 

days_missed_controller

  def create
    habit = Habit.find(params[:habit_id])
    habit.missed_days = habit.missed_days + 1
    @habit.save!
    level = habit.levels.find(params[:level_id])
    level.missed_days = level.missed_days + 1
    if level.missed_days == 3
      level.missed_days = 0
      level.days_lost += habit.calculate_days_lost + 2
    end
    level.save!
    head :ok # this returns an empty response with a 200 success status code
  end

这是要点.

Here's the Gist of it.

推荐答案

在习惯.rb 中添加方法 current_habit_level ，该方法将使用 current_level 并为该习惯获取 level_id.这样当您点击链接时，它会通过正确的级别，并且不会在搜索时崩溃

Add method current_habit_level in habit.rb which will use current_level and fetch level_id for that habit. So that when you click the link it will pass correct level is and it won't crash on searching

  def current_habit_level
    self.levels.order("id asc").limit(current_level).last
 end

使用此方法获取链接中的级别 id

Use this method to fetch level id in link
