Django-上传图片

1. 模型定义中将属性定义成 models.ImageField 类型

pic=models.ImageField(upload_to='cars/')

2. 图片存储路径--settings.py 文件中增加 media_root 项

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

3. html模板

<form method="post" action="/upload/" enctype="multipart/form-data">
  <input type="text" name="title"><br>
  <input type="file" name="pic"/><br>
  <input type="submit" value="上传">
</form>

form表单中一定要加enctype="multipart/form-data"
multipart/form-data是将文件以二进制的形式上传，这样可以实现多种类型的文件上传

4. 视图代码-处理函数

引用模块
from django.conf import settings

def upload(request):
  if request.method == "POST":
    f1 = request.FILES['pic']
    fname = '%s/%s' % (settings.MEDIA_ROOT, f1.name)
    with open(fname, 'wb+') as pic:
      for c in f1.chunks():
        pic.write(c)
     return HttpResponse("ok")
  else:
    return HttpResponse("error")

5. 应用url配置

url(r'^upload/$', views.upload)
