在您将其标记为重复之前，我已阅读ValueError: Missing staticfiles manifest entry for 'favicon.ico' ，但这并未解决我的问题。
我有以下型号：
from django.contrib.staticfiles.templatetags.staticfiles import static
class Profile(models.Model):
user = models.ForeignKey(SocialUser, on_delete=models.PROTECT)
avatar_url = models.URLField(
default=static('pledges/images/no-profile-photo.png'))
我正在使用Codeship for CI，当我运行时：
$ python manage.py collectstatic --noinput
我收到以下错误：

我本地没有问题，所以我想知道是什么导致了这个问题以及如何解决它。我从代码中理解的是，我不能将函数static用于模型字段。
有人知道怎么弄清楚这个吗？有人可以解释一下为什么会这样吗？
答案 0 :(得分：1)
您可以通过将static()调用移出模型字段并将默认值更改为字符串"pledges/images/no-profile-photo.png"来规避此问题并改进代码。它应该是这样的：
avatar_url = models.URLField(default='pledges/images/no-profile-photo.png')
访问avatar_url时，请使用
（前端/ Django模板选项）{% static profile_instance.avatar_url %}，其中profile_instance是引用Profile对象的上下文变量。
（后端/ Python选项）使用static(profile_instance.avatar_url)。
通过使用static()的结果作为默认值，应用程序在数据库中放置一个包含STATIC_URL前缀的URL - 这就像硬编码一样，因为数据不会在settings.py时更改。更一般地说，您不应该将static()的结果存储在数据库中。
如果您确保每次访问{% static %}以便在前端显示时使用static()标记或avatar_url功能，STATIC_URL仍将是在运行时根据您的环境配置添加。
This SO thread has a lot of good content on staticfiles
看起来你有一个循环依赖：
collectstatic需要运行才能创建manifest.json
您的应用程序需要加载才能运行调用manage.py
static()命令
static()依赖于manifest.json中的条目来解决。
