Django 使用easy_thumbnails压缩上传的图片方法

THUMBNAIL_ALIASES = {
 '': {
  'avatar': {'size': (200, 200), 'crop': True},
 },
}

from easy_thumbnails.fields import ThumbnailerImageField

class GoodsImage(models.Model):
 Img = ThumbnailerImageField(upload_to='images/',blank=True)

from models import GoodsImage
def test(request):
 goods = GoodsMessage.objects.all().first() # 查到一个图片
 return render(request,'templates.html',{'img':goods}) # 使用模板

{% load thumbnail %} {# 装载easy_thumbnail #}
<img src="/media/{{ img.Img }}"> {# 原图 #}
<img src="/media/{{ img.Img.avatar.url }}"> {# 压缩图 #}

from easy_thumbnails.files import get_thumbnailer
from models import GoodsImage
def test2(request):
 goods = GoodsImage.objects.all().first()
 path = get_thumbnailer(goods.Img)
 print(path) # 注意，这里查到的是url编码的图片地址
 return HttpResponse(path)

goods = GoodsImage.objects.all().first()
goods.Img # 原图地址
goods.Img['avatar'] # 缩略图地址
goods.Img['avatar'].url # 经url编码后的缩略图地址
# avatar是你在setting.py中的缩略图尺寸名
