Django-将文件名列表呈现给模板 [英] Django - Render a List of File Names to Template

问题描述

我正在为图库页面生成模板。我的方法如下：

I am generating a template for an image gallery page. My approach is as follows:

• 从图像文件夹
  
  
  的子目录中托管图像
  • 图像文件夹的标题将与画廊标题相同
  
  

  所以我的观点是

  def some_gallery(request):
      #LOGIC TO GET A LIST OF FILENAMES
  
      variables = RequestContext(request,{
          'user' : request.user,
          'title' : 'something',
          'files' : fileList
      })
      return render_to_response('gallery_template.html',variables)
  

  和模板

  ....
  {% for file in files %}
      <img src="/path/to/images/{{ title }}/{{ file }}">
  {% endfor %}
  ....
  

  我的问题遇到的是，当我尝试使用os.listdir函数时，Django出现500错误。如何获取所需的文件列表？

  The problem I am running into is that Django is putting up a 500 error when I try to use the os.listdir function. How can I get the file list that I need??

  视图的问题版本给出500错误

  Problematic version of the view which is giving the 500 error

  def some_gallery(request):
  
      variables = RequestContext(request,{
          'user' : request.user,
          'title' : 'something',
          'files' : os.listdir('/path/to/gallery')
      })
      return render_to_response('gallery_template.html',variables)
  

  另外，我应该注意文件路径确实有效，所以如果我直接进入url，我会得到只是预期的图像。

  Also I should note that the file path does work, so if I go directly to the url, I get just the image as expected.

  编辑：修复了代码示例中的错字

  Fixed the typos in code samples

  推荐答案

  我弄清楚了。我的方法是正确的，所以任何想做这种事情的人，代码示例都可以工作。

  I got it sorted out. My methods were correct, so anyone looking to do this type of thing, the code samples should work.

  我遇到的问题是Django在listdir上跳闸了由于访问提供的文件路径时遇到一些问题而导致函数调用。我确保目录权限和路径正确，并且可以正常工作。

  The problem that I had was that Django was tripping up on the listdir function call due to some problems accessing the file path that was provided. I made sure the directory permissions and path was correct and it worked.

  感谢那些提供帮助的人。

  Thanks to those that helped.
