Bootstrap传送带在Rails中 [英] Bootstrap Carousel in Rails

问题描述

我正在一个文件夹中包含多个图像的项目。我已经让Bootstrap从事我的项目，并尝试使用本教程在轮播中工作。一个>。它似乎很适合我的需求，但是在将其混入Ruby视图时遇到了麻烦。这是到目前为止我得到的：

I'm working a project that has several images inside of a folder. I've got Bootstrap working on my project, and was attempting to work in a carousel using this tutorial. It seems to be an ideal fit for my needs, but I'm having trouble mixing it into my Ruby view. Here's what I've got so far:

<div id="myCarousel" class="carousel slide" data-ride="carousel">
  <!-- Indicators -->
  <ol class="carousel-indicators">
    <% @patient.images.each do |image| %>
    <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
    <% end %>
  </ol>

  <!-- Wrapper for slides -->

      <div class="carousel-inner" role="listbox">
       <div class="item active">
        <% @patient.images.each do |image| %>
        <%= image_tag image.image_file.url %>
        <% end %>
        </div>
      </div>


<!-- Left and right controls -->
  <a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>
</div>

我认为我的div和图片标签位于语法/顺序问题上，但是移动它们不会改变任何东西。我想做的是每个图像都有一张单独的幻灯片，但是使用当前代码，似乎要把所有图像放在一张幻灯片中。

I think I've got a syntax/order issue where my divs and my image tags lie, but moving them around doesn't change anything. What I'm trying to do is have a seperate slide for each image, but using the current code it seems to want to put all of the images in one slide.

推荐答案

这是我的工作方式：

<ol class="carousel-indicators">
   <% @patient.images.each_with_index do |photo, n| %>
     <li data-target='#MyCarousel' data-slide-to="#{n}" class="#{'active' if n == 0}"></li>
   <% end %>
</ol>

<div class="carousel-inner" role="listbox">
  <div class="item active">
    <%= image_tag @patient.images.first.image_file.url %>
  </div>
  <% @patient.images.drop(1).each do |photo| %>
     <div class="item">
       <%= image_tag photo.image_file.url %>
     </div>
  <% end %>
</div>
