django后台处理前端上传和显示图片

1：项目根目录存放图片的目录

2：settings.py  添加

MEDIA_ROOT = os.path.join(BASE_DIR, "media")

3：url.py 添加后面路径自己定义

import django.views.static
 url(r'^media/(?P<path>.*)',django.views.static.serve,{'document_root':'C:\Users\Administrator\PycharmProjects\itracnew\itrac\media'}),

4：views.py

from xxx import settings
def test(request):

    if request.method =="POST":

        f1 = request.FILES['pic']

        fname = '%s/%s' % (settings.MEDIA_ROOT, f1.name)

        picname = fname.split(".")[0]+".png"

        with open(picname, 'wb') as pic:

            for c in f1.chunks():

                pic.write(c)

        print("picture OK",picname)

        post_pic = str(picname.split("/")[1])

5:html文件

  <div class="control-group">

        <div class="input-group">

            <span class="input-group-addon control-label" for="issue">上传图片（可选）:</span>

            <input type="file" name="pic" id="pic" accept="image/*" class="upload-input">

     </div>

  </div>

6：我在models文件加了一个字段方便存名字调用

    pict = models.CharField(max_length=100,null=True,blank=True)
