Python 3.x 烧瓶无线电场在form POST中不工作

有人能在下面的代码片段中帮助解决RadioField Post问题吗 如下代码未移动

表单。请在提交（）时验证

**validatingSPLForm.html**
{%extends“layout.html”%}
{%block content%}
{%endblock内容%}
{%block content1%}
“{form.srcfile.data.filename}}”有效，请选择以下SPL之一进行进一步验证
{{form.SPLFiles（）}}
{%endblock content1%}
有错误吗？如果是，请更新相同的..此代码是否完整？我没有看到提交按钮。。。？
**forms.py**
class validatingSPLForm(FlaskForm): 
    srcfile = FileField('Select Source ZIP', validators=[FileRequired(), FileAllowed(['zip'], 'Only ZIP files are allowed')])
    submit = SubmitField("Validate")
    proceed = IntegerField()
    SPLFiles = RadioField('SPL', choices=[])
    archiveresult = []

**routes.py**
app.route('/validatingSPLForm', methods=['GET', 'POST'])
def validatingSPLForm():
    form = validatingSPLForm()    
    if request.method == 'POST':
        if form.validate_on_submit():          
           form.SPLFiles.choices = [(elem.name, elem.des) for elem in form.archiveresult]

**validatingSPLForm.html**
{% extends "layout.html" %}
{% block content %}
    <div class="content-section">
        <form method="POST" action="" enctype="multipart/form-data">
           
        </form>
    </div>
{% endblock content %}
{% block content1 %} 
        <div class="content-section">             
            <h6><b class="text-success">"{{ form.srcfile.data.filename }}"</b> is valid, select one of the below SPL for further validation </h6>
            {{ form.SPLFiles() }}            
        </div>

{% endblock content1 %}
