如何让level.missed_days = habit.missed_days? [包括要点]

How to make level.missed_days = habit.missed_days? [Gist Included]

我正在尝试将养成良好习惯游戏化。

当用户养成新习惯时,有 5 个级别才能达到 "mastery"!每个级别都有一定的天数与之相关(如 habits.rb n_days 所示)。

这就是我卡住的地方:尽管在 :habit _form 中选中 :level 1 的 missed_days 框,控制台显示 missed_days: 0 [=23] =] 但 missed_days: 1Level.find(1)

错过一天是一件坏事,因为这个想法是,如果你错过了一天(通过选中一个框来表示),那么一天就会添加回你的 current_level(通过 days_missed 控制器),换句话说,只有完成的天数才计入完成一个级别。

我们怎样才能使 :level 中有多少 :missed_days 也将是 :habit 中的相同整数?

习惯 has_many 级别。

习惯_形式

  <label id="<%= @habit.id %>" class="habit-id"> Missed: </label>
    <% @habit.levels.each_with_index do |level, index| %>
      <p>
        <label id="<%= level.id %>" class="level-id"> Level <%= index + 1 %>: </label>
        <%= check_box_tag nil, true, level.missed_days > 0, {class: "habit-check"} %>
        <%= check_box_tag nil, true, level.missed_days > 1, {class: "habit-check"} %>
        <%= check_box_tag nil, true, level.missed_days > 2, {class: "habit-check"} %>
      </p>
    <% end %>
<% end %>

habit-check 是关于 habit.js

$(document).ready(function()
{
  $(".habit-check").change(function()
  {
    habit = $(this).parent().siblings(".habit-id").first().attr("id");
    level = $(this).siblings(".level-id").first().attr("id");
    if($(this).is(":checked"))
    {
       $.ajax(
       {
         url: "/habits/" + habit + "/levels/" + level + "/days_missed",
         method: "POST"
       });
    }
    else
    {
       $.ajax(
       {
         url: "/habits/" + habit + "/levels/" + level + "/days_missed/1",
         method: "DELETE"
       });
    }
  });
});

当我点击一个复选框时,终端会发生以下情况:

要点如下:https://gist.github.com/RallyWithGalli/c66dee6dfb9ab5d338c2

您错过的天数可能没有显示,因为您的复选框实际上没有名称或 ID。他们有 "nil" 而不是......尝试:

<%= check_box_tag "missed_days_1", true, level.missed_days > 0, {class: "habit-check"} %> 

或类似...第二个和第三个是 2 和 3...请记住,复选框不会给你 missed_days => 1 如果你真的想要 :missed_days =>1 然后你需要单选按钮...但你仍然需要给他们一个名字 :missed_days

"Is there a way we can make clicking a checkbox = 1 as I attempted in the days_missed controller"

也许 - 你可以设置一个复选框的值 returns 当被选中时...... check_box_tag doco 你在第二个参数中传递它(而不是 true)。但问题是你有多个复选框,如果你的复选框被命名为相同的东西,它们将相互覆盖,只有最后一组的值会得到 returned.

试试这样命名它们:看看你得到的结果是什么。然后处理您需要破译其含义的代码,然后将正确的值放在正确的位置。

<% @habit.levels.each_with_index do |level, index| %>
  <%= check_box_tag "missed_days[#{level}][1]", true, level.missed_days > 0, {class: "habit-check"} %> 
  <%= check_box_tag "missed_days[#{level}][2]", true, level.missed_days > 0, {class: "habit-check"} %> 
  <%= check_box_tag "missed_days[#{level}][3]", true, level.missed_days > 0, {class: "habit-check"} %>
<% end %>

给定 rails' 默认值...其中第一个可能 转换为 "true"...(您需要自己检查 return 值以确定是否属于这种情况)

改变模型和控制器。

habits.rb模型

    def current_level
            return 0 unless date_started
            committed_wdays = committed.map { |day| Date::DAYNAMES.index(day.titleize) }
            n_days = ((date_started.to_date)..Date.today).count { |date| committed_wdays.include? date.wday } - self.missed_days #Added this line here.

我修好了控制器,这是我达到等级 missed_days 的地方 missed_days:

class DaysMissedController < ApplicationController
before_action :logged_in_user, only: [:create, :destroy]

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
  level.save!
  head :ok # this returns an empty response with a 200 success status code
end

def destroy
  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
  level.save!
  head :ok # this returns an empty response with a 200 success status code
end
end
