下面显示了我的示例项目。但它在提交时引发错误。我已将 enctype 添加到表单字段。但没办法。请帮忙:)

html

<form class="forms2" action="." method="post" enctype="multipart/form-data">{%csrf_token%}
            <fieldset>
              <ol>

                   {% for field in forms %}
                   <li class="form-row">

                  <b>{{ field.label_tag }}</b> {{ field }} </li>
                  <i>{{ field.errors }}</i>


                  {%endfor%}



                  <li class="button-row">
                  <input type="submit" value="Submit" name="submit" class="btn-submit" />
                </li>

我在提交表单时遇到错误

没有提交文件。检查表单上的编码类型。

标签： django django-forms django-views

【解决方案1】：

您需要使用request.POST 和request.FILES 实例化您的表单。

form = CarrerApplication(request.POST, request.FILES)

有关更多信息，请参阅binding uploaded files to a form 上的文档。

【讨论】：

如果您使用的是TextInput 小部件，为什么applicant_mobile 是FileField？
错字，谢谢告知。

【解决方案2】：

这样做会很酷

form = CarrerApplication((request.POST,request.FILES) or None)
if request.method == 'POST':
     .......

【讨论】：

form = CarrerApplication(request.POST,request.FILES or None) (就够了)。

【解决方案3】：

我也遇到这个问题，我把FileInput改成ClearableFileInput。

applicant_resume = forms.FileField(widget=forms.ClearableFileInput(attrs={'name':'applicant_resume'}),label='Resume')

【讨论】：

只是为了澄清，这是您解决问题的方法吗？
