如何按升序重新排列卡片 django

Question

我有一个页面，其中卡片中的客户名称未按字母顺序按升序重新排列 例如：B、M、S。我如何让它按字母顺序排列，以便首先出现客户名称为曼谷航空公司的卡片，然后出现马来西亚航空公司的卡片，依此类推？

views.py

def outgoinggallery(request):
    user = request.user

    category = request.GET.get('category')

    if category == None:
        alloutgoinglru = OutgoingLRU.objects.filter(category__user=user)
    else:
        alloutgoinglru = OutgoingLRU.objects.filter(category__name=category, category__user=user)
        # if query:
        # return OutgoingLRU.objects.filter(title__icontains=query)



    categories = Category.objects.filter(user=user)
    context = {'categories': categories, 'alloutgoinglru': alloutgoinglru}

    return render(request, 'Outgoing/outgoinggallery.html', context)

outgoinggallery.html

Answer 1

升序： alloutgoinglru = alloutgoinglru.order_by('category__name')

降序： alloutgoinglru = alloutgoinglru.order_by('-category__name')

Answer 2

models.py

class Category(models.Model):
    user = models.ForeignKey(
      User, on_delete=models.SET_NULL, null=True, blank=True)
    name = models.CharField(max_length=100, null=False, blank=False)
   
    class Meta:
       ordering = ('name',)
       verbose_name = 'Category'
       verbose_name_plural = 'Categories'

   def __str__(self):
       return self.name


class OutgoingLRU(models.Model):

    category = models.ForeignKey(Category, on_delete=models.SET_NULL, null=True, blank=True)
    image = models.ImageField(null=False, blank=False)
    equipmentimages = models.ImageField(null=False, blank=False)
    boximages = models.ImageField(null=False, blank=False)
    documentimage = models.ImageField(null=False, blank=False)

    datetime = models.DateTimeField()  # datetime is the date and time the form was created
    serialno = models.TextField()  # serialno stand for serial number
    partno = models.TextField()  # partno stand for part number
    Deliveryor = models.TextField()  # deliveryor stand for delivery order
    MCO = models.TextField()
    descriptionequipment = models.TextField()  # A short description about the equipment (*Optional)
    descriptionequipmentbox = models.TextField()  # A short description of the equipment in the box (*optional)
    descriptionbox = models.TextField()  # A short description of the box (*optional)
    document = models.TextField()  # A short description of the delivery note document (*optional)

    class Meta:
        verbose_name = 'OutgoingLRU'
        verbose_name_plural = 'OutgoingLRUs
        ordering = ('category__name',)

    def __str__(self):
        return self.descriptionequipment

之后：
1) 运行 python manage.py makemigrations
2) 运行 python manage.py migrate
