Rails 4 x Bootstrap 3 Datetimepicker：用datetimepicker替换默认的datetime

本文介绍了Rails 4 x Bootstrap 3 Datetimepicker：用datetimepicker替换默认的datetime_select的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

在我已经使用Bootstrap 3的Rails 4应用程序中，我刚刚添加了

尽管设计还很不完善，但现在，这并不是我所关心的

真正的问题是，当我创建帖子时， date 属性（即 datetime 数据类型）设置为 nil ，而不是在 datetimepicker 。

我在网上寻找类似情况，发现的最接近的是此堆栈溢出问题。

不幸的是，它基于细长形式，并且我不知道如何将它们转换为常规格式，以用于 erb.html 文件。

是否知道我的代码有什么问题？

更新：我发现一种在创建帖子时实际上将日期保存到数据库的方法：

< div class = form-group id = post_date_time> <％= f.label：date， DATE& TIME％> < div class ='输入组日期'id ='datetimepicker'> <％= f.text_field：date，：class => 形式控制％> < span class = input-group-addon> < span class = glyphicon glyphicon-calendar< / span> < / span> < / div> < / div> < script type = text / javascript> $（function（）{ $（’＃datetimepicker'）。datetimepicker（）; }）; < / script>

但是，它似乎在编辑表单上无法正常工作，因为我没有datetimepicker填充了发布日期。我在这里错过了什么吗？

解决方案

要在编辑页面上填充日期时间，可以在javascript设置中执行以下操作：

< script type = text / javascript> $（function（）{ $（'＃datetimepicker'）。datetimepicker（{ defaultDate：<％= @ post.date％>，格式： YYYY-MM-DD hh：mm a Z }）; }）; < / script>

我在这里有工作代码： Github-Rails Datetimepicker示例

In my Rails 4 app, which already uses Bootstrap 3, I just added Datetimepicker by eonasdan.

I carefully followed the instructions offered here and there to install the plugin.

Here is my setup:

Gemfile

gem 'momentjs-rails' gem 'bootstrap3-datetimepicker-rails'

application.js

//= require jquery //= require jquery.turbolinks //= require jquery_ujs //= require bootstrap //= require bootstrap/dropdown //= require moment //= require bootstrap-datetimepicker //= require turbolinks //= require_tree .

application.scss

@import "bootstrap-sprockets"; @import "bootstrap"; @import 'bootstrap/theme'; @import 'bootstrap-datetimepicker'; @import "font-awesome-sprockets"; @import "font-awesome"; @import "simple_calendar"; @import "custom.scss"; @import "custom/**/*"

And I do have restarted my server.

Now, I am trying to use the plugin in my Posts#New and Posts#Edit views form, to replace the current datetime_select field:

<div class="field"> <%= f.label :date, "DATE" %> <%= f.datetime_select :date %> </div>

This is where I am after my first attempt:

<div class="form-group"> <div class='input-group date' id='datetimepicker'> <%= f.label :date, "DATE & TIME" %> <%= f.text_field :date, :class => "form-control"%> <span class="input-group-addon"> <span class="glyphicon glyphicon-calendar"></span> </span> </div> <script type="text/javascript"> $(function () { $('#datetimepicker').datetimepicker(); }); </script> </div>

Which gives me the following elements in the view:

Although the design is far from perfect, for now, this is not what I am concerned about.

The real problem is that, when I create a post, the date attribute (which is a datetime data type) is set to nil, instead of the value chosen in the datetimepicker.

I looked for similar situations online, and the closest I have found is this Stack Overflow question.

Unfortunately, it is based on slim forms, and I don't know how to "translate" them into regular forms, to be used in a erb.html file.

Any idea of what is wrong with my code?

UPDATE: I have found a way that is actually saving the date to the database when the post is created:

<div class="form-group" id="post_date_time"> <%= f.label :date, "DATE & TIME" %> <div class='input-group date' id='datetimepicker'> <%= f.text_field :date, :class => "form-control"%> <span class="input-group-addon"> <span class="glyphicon glyphicon-calendar"></span> </span> </div> </div> <script type="text/javascript"> $(function () { $('#datetimepicker').datetimepicker(); }); </script>

However, it does not seem to work properly on the edit form, since I don't get the datetimepicker populated with the date of the post. Am I missing something here?

解决方案

To get the datetime populated on your edit page you can do this in the javascript setup:

<script type="text/javascript"> $(function () { $('#datetimepicker').datetimepicker({ defaultDate: "<%= @post.date %>", format: "YYYY-MM-DD hh:mm a Z" }); }); </script>
