参数的Python NoReverseMatch

我是Python Django新手，我正在努力解决URL模式问题，我创建的网站有三个Html页面和它们各自的三个视图，我正在链接代码和项目结构的图像请帮助我找到解决方案： 项目结构：-

所以，我的想法是，当我点击index.html时，页面会重定向到detail.html，图像id为'music/id'，现在我想重定向到image上的其他html页面，点击detail.html到picturedeail.html，属性为'song\u title'

代码：-

Models.py：-

from django.db import models



class Album(models.Model):
  art_type=models.CharField(max_length=255)
  album_title=models.CharField(max_length=255)
  art_method=models.CharField(max_length=255)
  album_logo=models.FileField()

def __str__(self):
    return self.album_title;


class Picture(models.Model):
  album=models.ForeignKey(Album,on_delete=models.CASCADE)
  file_type=models.FileField()
  song_title=models.CharField(max_length=245)

detail.html：-

  {% extends 'music/base.html'  %}
  {% block title %}Album Details{% endblock %}
  {% block body %}
  <ul>
     {% for picture in album.picture_set.all %}
      <div class="col-sm-4 col-lg-2">
           <div class="thumbnail">
              <a href="{% url 'music:picturedetail' picture.song_title %}">
               <img src="{{ picture.file_type.url }}" class="img-responsive">
                        </a>
                        <div class="caption">
                          <h6>{{picture.song_title}}</h6>
                        </div>
                </div>

        </div>

     {% endfor %}
  </ul>

我得到的错误是：-
