how to understand which form is submitted if i have multiple forms in a page django code example

Example 1: working with multiple html forms django

# views.py
def _get_form(request, formcls, prefix):
    data = request.POST if prefix in request.POST else None
    return formcls(data, prefix=prefix)

class MyView(TemplateView):
    template_name = 'mytemplate.html'

    def get(self, request, *args, **kwargs):
        return self.render_to_response({'aform': AForm(prefix='aform_pre'), 'bform': BForm(prefix='bform_pre')})

    def post(self, request, *args, **kwargs):
        aform = _get_form(request, AForm, 'aform_pre')
        bform = _get_form(request, BForm, 'bform_pre')
        if aform.is_bound and aform.is_valid():
            # Process aform and render response
        elif bform.is_bound and bform.is_valid():
            # Process bform and render response
        return self.render_to_response({'aform': aform, 'bform': bform})

# mytemplate.html
<form action="" method="post">
    {% csrf_token %}
    {{ aform.as_p }}
    <input type="submit" name="{{aform.prefix}}" value="Submit" />
    {{ bform.as_p }}
    <input type="submit" name="{{bform.prefix}}" value="Submit" />
</form>

Example 2: how to submit two forms in django

if request.method == 'POST':
    form1 = Form1( request.POST,prefix="form1")
    form2 = Form2( request.POST,prefix="form2")
    
    if form1.is_valid():
       # save them    
       
       # context['form1_message'] = 'Form1 saved'
    else: 
       #save them into context
       context['form1']= form1
    
    if form2.is_valid():
       # save them    
       # context['form2_message'] = 'Form2 saved'
    else: 
       #save them into context
       context['form2']= form2

    if form1.is_valid() and  form2.is_valid(): 
       #that's mean both form is valid and saved successfully 
       return redirect('page')
    else:
        return render('/page', context)


else:
    form1 = Form1(prefix="form1")
    form2 = Form2(prefix="form2")
