模块 'django.db.models' 没有属性 'Foreignkey'

Question

我是Django的新手，我刚刚开始使用Djaango示例学习它，但我收到错误消息。这是我的回溯

C:UsersHarsleyshop>python manage.py makemigrations

AttributeError: module 'django.db.models' has no attribute 'Foreignkey'

这是模型文件，我已经浏览了它，似乎我没有犯任何错误。

from django.db import models
# Create your models here.
class Category(models.Model):
    name = models.CharField(max_length=200, db_index=True)
    slug = models.SlugField(max_length=200, db_index=True, unique = True)
    class Meta:
        ordering = ('name',)
        verbose_name = 'category'
        verbose_name_plural = 'categories'
        def ___str__(self):
            return self.name
class Product(models.Model):
    category = models.Foreignkey(Category,related_name='products')
    name = models.CharField(max_length=200, db_index=True)
    slug = models.SlugField(max_length=200, db_index=True)
    image = models.ImageField(upload_to='products/%Y/%m/%d', blank=True)
    description = models.TextField(blank=True)
    price = models.DecimalField(max_digits=10, decimal_places=2)
    stock = models.PositiveIntegerField()
    available = models.BooleanField(default=True)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    class Meta:
        ordering = ('name',)
        index_together = (('id', 'slug'),) 
    def __str__(self):
        return self.name

你在代码中拼错了ForeignKey，k应该是大写的。

class Product(models.Model):
    category = models.ForeignKey(Category,related_name='products')
    name = models.CharField(max_length=200, db_index=True)
    slug = models.SlugField(max_length=200, db_index=True)
    image = models.ImageField(upload_to='products/%Y/%m/%d', blank=True)
    description = models.TextField(blank=True)
    price = models.DecimalField(max_digits=10, decimal_places=2)
    stock = models.PositiveIntegerField()
    available = models.BooleanField(default=True)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    class Meta:
        ordering = ('name',)
        index_together = (('id', 'slug'),) 
    def __str__(self):
        return self.name
