来自文档:

render_to_response(template_name, context=None, content_type=None, status=None, using=None)

Deprecated since version 2.0.

This function preceded the introduction of render() and works similarly except that it doesn’t make the request available in the response.

你把一对夫妻的关系搞错了。形象应该是产品的外键。这样,一个产品可以有多个图像。

class Image(models.Model):
    image = models.ImageField()
    imageMetaKeyWords = models.CharField("Meta keywords for SEO", max_length = 255,
    help_text = "Comma delimited words for SEO")
    imageMetaDescription = models.CharField("Meta description", max_length = 255,
    help_text = "Content for image meta tag description")
    defaultImage = models.BooleanField(default= False)
    product = models.ForeignKey("Product", on_delete=models.CASCADE, related_name="images") 
    #if you want to get the product's images you can call product.images

并删除以下内容:

productImages = models.ForeignKey(Image, on_delete=models.CASCADE)

迁移,然后在你的管理员。py:

from django.contrib import admin
from .models import Product, Image
from .forms import ProductAdminForm

# Register your models here.
class ImageTabularInline(admin.TabularInline):
    model = Image

class ProductAdmin(admin.ModelAdmin):
    form = ProductAdminForm
    inlines = [ImageTabularInline,]
    
    class Meta:
        model = Product

admin.site.register(Image)
admin.site.register(Product, ProductAdmin)
