Question

我有一个页面，其中嵌套在我的表单中的列表中的项目可以被收藏，它会重定向回到应该对数据库进行更新的同一页面，然后它会在项目旁边显示一个星号。虽然这应该工作正常我的表格根本不会改变数据库。我相信它不是html渲染，因为当我手动更改管理面板中的字段时，它呈现得很好。是什么导致这不发布？

view.py：

<img src="{{album.album_logo}}">

<h1>{{album.album_title}} </h1>
<h2>{{album.artist}} </h2>

{% if error_message %}
	<p><strong> {{error_message}} </strong></p>
{% endif %}

<form action="{% url 'music:favorite' album.id %}" method="post">
	{% csrf_token %}
	{% for song in album.song_set.all %}
		<input type="radio" id="song{{forloop.counter}}" name="song" value="{{song.id}}" />
		<label for="song{{forloop.counter}}">
			<span>{{song.song_title}}
			{% if song.is_favorite %}
				<img src="http://i.imgur.com/b9b13Rd.png" />
			{% endif %}
		</span>
		</label><br>
	{% endfor %}
	<input type="submit" value="Favorite">
</form>
