class Product(models.Model):

short_description = models.CharField(max_length=200, blank=True)
description = models.TextField(blank=True)
product_information = models.TextField(blank=True)
price = models.DecimalField(max_digits=10, decimal_places=0)
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
def get_absolute_url(self):
return reverse('shop:product_detail',
args=[self.category.slug, self.slug])
class Images (models.Model):
product = models.ForeignKey(Product, default=None, related_name='images')
image = models.ImageField(upload_to='products/%Y/%m/%d', blank=True)
但我不能通过管理员页面上传图片。
管理员
class ProductAdmin(admin.ModelAdmin):
list_display = ['name', 'slug', 'category', 'price', 'stock', 'available', 'created', 'updated']
list_filter = ['available', 'created', 'updated', 'category']
list_editable = ['price', 'stock', 'available']
prepopulated_fields = {'slug': ('name',)}
admin.site.register(Product, ProductAdmin)
我应该如何更改代码,以便能够使用管理页面为我的产品添加多个图像?
我应该如何在页面代码中调用图像
现在我使用{{product.image}调用image
我已经花了很多时间来寻找答案。请帮忙 这里可以使用的是管理内联线,帮助您轻松编辑/更新相关项目
class ProductImagesInline(admin.StackedInline):
model = Images
class ProductAdmin(admin.ModelAdmin):
list_display = ['name', 'slug', 'category', 'price', 'stock', 'available', 'created', 'updated']
list_filter = ['available', 'created', 'updated', 'category']
list_editable = ['price', 'stock', 'available']
prepopulated_fields = {'slug': ('name',)}
inlines = [ProductImagesInline]
一旦有了图像,您就可以像product.images.all()
一样访问它们。请为图像使用一个管理员(是的,您应该给它一个单数名称!)型号:
<>在模板中适当显示图像时,应该考虑缩略图库,如:
#一些示例
{%用于product.images.all%中的图像}
{%thumbnail image.image“500x500”format=“PNG”upscale=False as thumb%}
#^^^^^此处需要图像字段
{%endthumbnail%}
{%endfor%}
除此之外,您还可以通过访问图像的url。这是您的原始图像文件将被送达的地方。这要求您正确配置MEDIA\u ROOT
和MEDIA\u URL
。django返回名称错误:名称“Image”未定义是的,我擅自更改了您的型号名称,从“Images”
;-)django返回NameError:name'Images'未定义您需要从顶部的模型导入它
