Modul 'django.db.models' hat kein Attribut 'Fremdschlüssel'

Question

Ich bin neu in Django und ich habe gerade angefangen, es mit Djaango zu lernen, aber ich bekomme Fehlermeldungen. Hier ist mein Traceback

C:\Users\Harsley\shop>python manage.py makemigrations 
Traceback (most recent call last):

    category = models.Foreignkey(Category,related_name='products') 
AttributeError: module 'django.db.models' has no attribute 'Foreignkey' 

Dies ist die Modell-Datei, und ich habe es durchgemacht, und es scheint, dass ich keinen Fehler gemacht habe. i

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

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
