Question

我有以下表格，允许用户提交文件和电子邮件地址。

from django import forms
from django.utils.translation import gettext_lazy as _
from django.core.validators import validate_email

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

class EmailField(forms.CharField):
    default_error_messages = {
        'invalid': _(u'Enter a valid e-mail address.'),
    }
    default_validators = [validate_email]

以下是观点：

def upload_file(request):

    if request.method == 'POST':
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            email = form.cleaned_data['email']
            handle_uploaded_file(email, request.FILES['file'])
            return HttpResponseRedirect('/thanks')
    else:
        form = UploadFileForm()
    return render_to_response('upload_file.html', {'form': form},   
        context_instance=RequestContext(request))

如果用户使用无效的电子邮件提交表单，表单将显示回用户，但字段将被清除。什么是阻止表单字段清除的正确方法？

愚蠢的错误。更新了我的模板以包含表单值。一切正常。
