Multiple Forms of the same Class

Hey Guys

I need some help with submitting and validating my form. I have a page 
that displays the same WTForm multiple times and I cannot get it to 
submit.

I came across a post where the suggestion was to add a prefix to the form.
This I have tried but the problem is that it is that same prefix for all 
form.
So how can I distinguish between the forms to submit them separately? I am
wondering if there is a pythonic / flask way to do it or if I have to use 
jQuery or something to that effect. Any advise is much appreciated.

Here my view:

@app.route('/domains/<domain>', methods = ['GET', 'POST'])
def dnsDisplay(domain=None):
  name='Zone Management'
  domain = domain or request.args.get('domain')
  title = 'Domains'
  Records = getRecords(domain)
  aRecords=[]
  for sublist in Records:
    if sublist[0] == 'A':
      sub={
      'type':sublist[0],
      'record':sublist[1],
      'ttl':sublist[2],
      'content':sublist[3]
      }
      aRecords.append(sub)
  aFrm = aForm(request.form,prefix='ARec')
  if aFrm.validate_on_submit() and aFrm.submit.data:
    print aFrm.data
  return 
render_template('selected.html',name=domain,title=title,aFrm=aFrm,aRec=aRecords)

the template:
{% extends 'base.html' %}
{%block main%}

{% for message in aFrm.errors %}
  <div id=flashes>
   {{ message }}
  </div>
{% endfor %}

<fieldset id=shadow>
<legend>A RECORDS</legend>
  {%for a in aRec%}
    <form method=POST action=. name={{a.record}}>
     {{aFrm.hidden_tag()}}
     {{aFrm.type(size=2,value=a.type)}}
     {{aFrm.record(size=15,value=a.record)}}
     {{aFrm.ttl(size=5,value=a.ttl)}}
     {{aFrm.content(size=15,value=a.content)}}
     {{aFrm.edit}}
   </form>
  {%endfor%}
</fieldset>

{%endblock%}

and the form:

class aForm(Form):
  type    = HiddenField('Type')
  regex   = re.compile('^[a-zA-Z0-9-]+$')
  record  = TextField('Hostname', validators=[Required(),Regexp(regex)])
  ttl     = TextField('TTL', 
validators=[Required(),NumberRange(min=60,max=84600)])
  content = TextField('Destination', validators=[Required(),IPAddress()])
  edit    = SubmitField('Update')
