Question

我正在尝试从简单的HMTL表单上传图像文件，我收到以下错误：

'MultiValueDict'对象没有属性'_committed'

我没有以同样的方式使用表单原因我需要一次上传多个文件，而且我知道Djangoforms只允许一次上传一个文件。

所以使用正常的方式似乎不起作用......

代码结构如下：

的 Models.py

<div class="container-fluid">
    <div class="row-fluid">
        <div class="span4">
            <div>
                <a class="brand" href="/{{locationService.getLangKey()}}" style="text-decoration: none"><img src="img/logo.png" /><span class="logo">yanpy</span></a>               
            </div>
        </div>
        <div class="span8 pull-right" style="padding-right: 10px">
            <div class="navbar">
                <div class="navbar-inner custom-navbar-inner">  
                    <!-- Responsive Navbar Part 1: Button for triggering responsive navbar (not covered in tutorial). Include responsive CSS to utilize. -->
                    <button type="button" class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
                        <span class="icon-bar"></span>
                        <span class="icon-bar"></span>
                        <span class="icon-bar"></span>
                    </button>
                    <!-- Responsive Navbar Part 2: Place all navbar contents you want collapsed withing .navbar-collapse.collapse. -->
                    <div class="nav-collapse collapse" style="padding-top: 4px">                   
                        <!--<div ng-include src="'partials/login.html'"></div>-->                     
                    </div><!--/.nav-collapse -->
                </div><!-- /.navbar-inner -->
            </div><!-- /.navbar -->
        </div> <!-- span8 -->
    </div>
</div>

HTML

class ProfileImage(models.Model):
    account_id = models.IntegerField(primary_key=True)
    image = models.ImageField(upload_to='profile/%Y/%m/%d')
    profile = models.CharField(max_length=512, blank=True)
    description = models.CharField(max_length=255, blank=True)
    class Meta:
        managed = False
        db_table = 'ProfileImage'

Views.py

  <form  id="fileinfo" name="fileinfo" action="profileimage" enctype="multipart/form-data" method="post" >
      {% csrf_token %}
      <table>
          <tr>
             <input type="file" size="60" id="myfile" name="myfile" multiple="false" value="Profile Picture"
             accept="image/gif, image/jpeg, image/png">
          </tr>
          <tr>
             <input type="submit" value="Upload" />
             <div id="accresult" name="accresult"></div>
          </tr>
      </table>
  </form>

参数正确到达但是当我尝试def profile_image(request): profile_image = ProfileImage(account_id=request.session.get('memberid', False), image=request.FILES, profile='', description='') try: print 'Userid: ', profile_image.account_id print 'File sent...', profile_image.image profile_image.save() except Exception as err: print 'Error: ', err.message useraccount = request.session.get('useraccount', False) return render(request, 'profileImage.html', {'useraccount': useraccount, 'image': profile_image})出现错误时，我刚尝试了很多方面，所以非常感谢您的帮助。

request.FILES是一个文件列表。您需要指定要传递给image参数的文件。喜欢这个。

profile_image = ProfileImage(account_id=request.session.get('memberid', False), image=request.FILES[0],  profile='', description='')

这不是很好，因为如果没有文件，它会引发异常。您可能需要使用Django form来更好地处理表单。
