Answer 1

Hi, you could use a hidden input.

#forms.py
class fontform(forms.ModelForm):
btn = forms.IntegerField(widget=forms.HiddenInput(attrs={'id' : 'myfieldid' })
class Meta:
model = layout
fields = ['btn']

#template
...
<form method='POST' action='{% url 'testview' %}'>
{{ form }}
<span id="preview">Text Size</span>
<button onclick='document.getElementById("myfieldid").value = parseInt(document.getElementById("myfieldid").value)+1;document.getElementById("preview").style.fontSize = document.getElementById("myfieldid").value + "px"'>
<button onclick='document.getElementById("myfieldid").value = parseInt(document.getElementById("myfieldid").value)-1;document.getElementById("preview").style.fontSize = document.getElementById("myfieldid").value + "px"'>
<input type="submit">
</form>
...

#views.py
def test_view(request):
if request.method == 'POST':
form = fontform(request.POST)
if form.is_valid():
form.save()
else:
form = fontform() return
render(request, 'home.html')

Or perhaps you could use a range input?
