我正在编写一个Django应用程序,它将获取特定URL的所有图像并将它们保存在数据库中.

但我没有介绍如何在Django中使用ImageField.

Settings.py

MEDIA_ROOT = os.path.join(PWD, "../downloads/")

# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash.
# Examples: "http://example.com/media/", "htp://media.example.com/"
MEDIA_URL = '/downloads/'

models.py

download_img.py

        PWD = os.path.dirname(os.path.realpath(__file__ ))
        #site="http://en.wikipedia.org/wiki/Pune"

        outfolder=os.path.join(PWD, "../downloads")
        #outfolder="/home/mayank/Desktop/dreamport/downloads"
        print "MAYANK:"+outfolder
        req = urllib2.Request(site,headers=hdr)
        page = urllib2.urlopen(req)
        soup =bs(page)
        tag_image=soup.findAll("img")
        count=1;
        for image in tag_image:
                print "Image: %(src)s" % image
                filename = …
