Django python如何在一个模型中获得多个图像

pip install django-imagekit

from django.db import models
from imagekit.models import ImageSpecField
from imagekit.processors import ResizeToFit

class MyModel(models.Model):
    image1 = models.ImageField(upload_to='images/')
    image2 = models.ImageField(upload_to='images/')
    image1_thumbnail = ImageSpecField(source='image1',
                                      processors=[ResizeToFit(200, 200)],
                                      format='JPEG',
                                      options={'quality': 90})
    image2_thumbnail = ImageSpecField(source='image2',
                                      processors=[ResizeToFit(200, 200)],
                                      format='JPEG',
                                      options={'quality': 90})

from django.shortcuts import render
from .models import MyModel

def my_view(request):
    my_model = MyModel.objects.first()
    context = {
        'image1_url': my_model.image1.url,
        'image2_url': my_model.image2.url,
        'image1_thumbnail_url': my_model.image1_thumbnail.url,
        'image2_thumbnail_url': my_model.image2_thumbnail.url,
    }
    return render(request, 'my_template.html', context)
