尝试将项目添加到模型时出现 Django FileNotFoundError

Question

我正在尝试使用 Django 和 python 创建一些模型。我所有的模型都在工作，我可以向模型添加项目，除了我的用户模型。谁能建议它有什么问题？

models.py

from django.db import models

# Create your models here.

class Item(models.Model):
    ID = models.IntegerField(auto_created=True, primary_key=True, unique=True)
    Name = models.CharField(max_length=30)
    Price = models.IntegerField()


class User(models.Model):
    ID = models.IntegerField(auto_created=True, primary_key=True)
    Nickname = models.CharField(max_length=50)
    Password = models.CharField(max_length=200)
    Mail = models.EmailField()
    Points = models.IntegerField()
    SaleItem = models.ForeignKey(Item, on_delete=models.CASCADE)
    ProfilePic = models.FilePathField()
    BannerPic = models.FilePathField()
    ZodiacSign = models.CharField(max_length=50)


class Friendship(models.Model):
    ID = models.IntegerField(auto_created=True, primary_key=True, unique=True)
    UserID = models.ManyToManyField(User, related_name="user")
    FriendID = models.ManyToManyField(User, related_name="befriended_user")


class ThreadPrivate(models.Model):
    ID = models.IntegerField(auto_created=True, primary_key=True, unique=True)
    Text = models.TextField()
    Sender = models.ForeignKey(User, on_delete=models.CASCADE, related_name="Sender")
    Receiver = models.ForeignKey(User, on_delete=models.CASCADE, related_name="Receiver")
    Time = models.DateTimeField(auto_now_add=True)


class Side(models.Model):
    ID = models.IntegerField(auto_created=True, primary_key=True, unique=True)
    Creator = models.ForeignKey(User, on_delete=models.CASCADE, related_name="creator_of_page")
    Time = models.DateTimeField(auto_now_add=True)


class ThreadPublic(models.Model):
    ID = models.IntegerField(auto_created=True, primary_key=True, unique=True)
    Text = models.TextField()
    Time = models.DateTimeField(auto_now_add=True)
    Sender = models.ForeignKey(User, on_delete=models.CASCADE, related_name="thread_sender")
    SideID = models.ForeignKey(Side, on_delete=models.CASCADE, related_name="side_for_thread")

和 admin.py

from django.contrib import admin
from .models import *
# Register your models here.

admin.site.register(Item)
admin.site.register(User)
admin.site.register(Friendship)
admin.site.register(ThreadPrivate)
admin.site.register(Side)
admin.site.register(ThreadPublic)

我记得在 settings.py 等中添加到 APPS。所有模型工作， 除了用户模型。有什么想法吗？

您必须提供用户模型的 FilePathField 的路径。根据this answer，您可以在设置中创建变量 FILE_PATH_FIELD_DIRECTORY，然后像这样使用它：

from django.conf import settings

class User(models.Model):
    ProfilePic = models.FilePathField(path=settings.FILE_PATH_FIELD_DIRECTORY)

将您的类名称更改为 CustomUser 会很有帮助，因此您不要将其与 django 中的 User 类混淆。
