python-3.x - 系统找不到指定的路径: error returned when changing field in admin page Django

Question

大家好，我只是按照本教程(https://realpython.com/get-started-with-django-1/)为我的Django投资组合站点项目集成了一个项目应用程序。
设置一切正常，直到我尝试登录Django的管理页面以向数据库中的Project模型添加更多对象。
单击添加后，它返回一个错误页面，并显示如下:
错误返回页[1]:/image/co1Cy.png

我的models.py

from django.db import models 
class Project(models.Model):
  title = models.CharField(max_length=100)
  description = models.TextField()
  technology = models.CharField(max_length=20)
  image = models.FilePathField(path='/projects/img/')

我的文件夹看起来像这样

 django-project
    projects
      static
        projects
          img
             -project1.png
             -project2.png
             -project3.png
...

感谢您的帮助，我发现了这个错误，
FilePathField方法接受比我认为需要的更多显式路径，因此我用将此模型替换为，它现在就像一个魅力

from django.db import models

# Create your models here.
class Project(models.Model):
    title = models.CharField(max_length=100)
    description = models.TextField()
    technology = models.CharField(max_length=20)
    image = models.FilePathField(path='projects/static/projects/img/')
    def __str__(self):
        return self.title```
