Question

我有以下表格（以及其他两种表格）：

class UploadFileForm(forms.Form):
    file = forms.FileField()

以下是我的HTML：

<div class="panel panel-danger">
                <div class="panel-heading">
                    <h3 class="panel-title">Panel title</h3>
                </div>
                <div class="panel-body">
                    <form action="" method="POST" role="form" enctype="multipart/form-data">
                        {% csrf_token %}
                        <legend>Upload a file: </legend>

                        <div class="form-group">
                            <input type="file" name="file" class="form-control" id="" placeholder="Input field">
                        </div>



                        <button type="submit" class="btn btn-primary">Submit</button>
                    </form>
                </div>
            </div>

完成文件处理：

if request.method == 'POST':
    print "I am in request."
    print request.FILES['file']
    # create a form instance and populate it with data from the request:
    formName = NameForm(request.POST)
    formHandle = HandleForm(request.POST)
    fileForm = UploadFileForm(request.POST)
    successMessages = []
    failureMessages = []
    # check whether it's valid:
    # 
    if fileForm.is_valid():
        print "file is uploaded."
        print request.FILES['file']
    else:
        print "File form is not set."

即使设置了request.files中的值，也会执行其他条件。我做错了什么？

您需要添加request.FILES，如下所示：

fileForm = UploadFileForm(request.POST, request.FILES)

django form.is_valid（）总是在文件上传的情况下返回0
