使用SQLite在Django中为每个实体对象存储多个图像

from django.db import models

class Entity(models.Model):
    name = models.CharField(max_length=100)
    # 其他属性...

    def __str__(self):
        return self.name

class Image(models.Model):
    entity = models.ForeignKey(Entity, on_delete=models.CASCADE)
    image = models.ImageField(upload_to='images/')
    # 其他属性...

    def __str__(self):
        return self.image.name

python manage.py makemigrations
python manage.py migrate

from django.shortcuts import render, redirect
from .models import Entity, Image

def upload_image(request, entity_id):
    entity = Entity.objects.get(id=entity_id)
    
    if request.method == 'POST':
        image_files = request.FILES.getlist('images')
        
        for image_file in image_files:
            Image.objects.create(entity=entity, image=image_file)
        
        return redirect('entity_detail', entity_id=entity_id)
    
    return render(request, 'upload_image.html', {'entity': entity})

<!-- entity_detail.html -->
<h1>{{ entity.name }}</h1>

{% for image in entity.image_set.all %}
    <img src="{{ image.image.url }}" alt="{{ image }}" width="200">
{% endfor %}

<form method="post" enctype="multipart/form-data">
    {% csrf_token %}
    <input type="file" name="images" multiple>
    <button type="submit">上传图像</button>
</form>

from django.urls import path
from .views import upload_image

urlpatterns = [
    # 其他URL配置...
    path('entity/<int:entity_id>/upload_image/', upload_image, name='upload_image'),
]
