Hey guys, I know this question has been brought up numerous times, but I'm not quite getting the full implementation. As you can see below, I've got a
form that I can dynamically tell how many rows to create. How can I create an "Add Row" link that tells the view how many rows to create? I would really like to do it without augmenting the url...
# views.py
def myView(request):
if request.method == "POST":
form = MyForm(request.POST, num_rows=1)
if
form.is_valid():
return render_to_response('myform_result.html', context_instance=RequestContext(request))
else:
form = MyForm(num_rows=1)
return render_to_response('myform.html', {'
form':form}, context_instance=RequestContext(request))
# forms.py
class MyForm(forms.Form):
def __init__(self, *args, **kwargs):
num_rows = kwargs.pop('num_rows',1)
super(MyForm, self).__init__(*args, **kwargs)
for row in range(0, num_rows):
field = forms.CharField(label="Row")
self.fields[str(row)] = field
# myform.html http://example.com/myform
<form action="." method="POST" accept-charset="utf-8">
<ul>
{%
for field in
form %}
<li style="margin-top:.25em">
<span class="normal">{{ field.label }}</span>
{{ field }}
<span class="formError">{{ field.errors }}</span>
</li>
{% endfor %}
</ul>
<input type="submit" value="Save">
</form>
<a href="ADD_ANOTHER_ROW?">+ Add Row</a>
