从wtforms获取表单数据并在上面写条件

如何解决从wtforms获取表单数据并在上面写条件

我正在尝试对wtfforms进行调查，但是我想让某个问题出现 根据用户的响应。获取用户选择信息的语法是什么 在调查中

表单代码

from wtforms import Form,SelectField,StringField,IntegerField,SelectMultipleField,SubmitField,BooleanField,validators 

class PhoneSurvey(Form):
    terminal_number = IntegerField('Terminal number')
    was_this_a_pandemic_related_call = SelectField('Was this a Pandemic related call',choices=[('yes','Yes'),('no','No')])
    what_was_the_call = SelectField('What category was this call',choices=[('get_food','NYC Get Food'),('covid_test','COVID-19 Testing'),('remote_learning','Remote Learning'),('other','Other')])
    pandemic_related_text = StringField('Briefly describe this pandemic related call?')
    non_pandemic_related_text = StringField('Briefly describe this non pandemic related call?')
    able_to_resolve_other_text = StringField('What happened to this call?')
    was_the_inquiry_resolved = SelectField('Was the inquiry resolved','No'),'Other')])
    inquiry_resolution_other = StringField('What happened to this call?')
    submit = SubmitField('Submit')

HTML

  <div class="form-field space"> {{ form.non_pandemic_related_text.label}}: {{ form.non_pandemic_related_text(class="css_class") }}</div>

试图弄清楚他们选择的是是还是否，然后从那里开始 显示其余的问题

喜欢

 {{ form.non_pandemic_related_text(class="css_class") }

    {%if form.non_pandemic_related_text.no}
       
       {% else %}
       
<div class="form-field space"> {{ form.able_to_resolve_other_text.label}}: {{ form.able_to_resolve_other_text(class="css_class") }}</div>

              <div class="form-field space"> {{ form.was_the_inquiry_resolved.label}}: {{ form.was_the_inquiry_resolved(class="select") }}</div>

              <div class="form-field space"> {{ form.inquiry_resolution_other.label}}: {{ form.inquiry_resolution_other(class="css_class") }}</div>

{%endif%}

        

    <div class="center space"> 
                 {{ form.submit(class="button is-primary is-rounded") }}
              </div>
