I am creating a form in Django. When I POST the data, the data is naturally sent. My problem is, I want to pass an additional property to the POST data, that is not any of the form fields, but an additional one.
So that I can later do something like (pseudocode):
def form_view(request):
if request.method == 'POST':
form = MyForm(request.POST)
if form.is_valid():
extra_field = form.cleaned_data['extra_field']
#or maybe
extra_field = form.extra_field
#...
else:
form = MyForm()
#...
Anything that might work in order to pass an extra property, which is not a field but a simple variable, to the POST request.
If you want to pass anything to django as a POST request from the HTML, you would use a hidden input
<input type="hidden" name="foo" value="bar" />
print request.POST['foo'] # out: bar
If you want to modify the POST dictionary in python from your view, copy() it to make it mutable.
mutable_post = request.POST.copy()
mutable_post['foo'] = 'bar'
form = MyForm(mutable_post)
In your form's clean method, you can add new information to the cleaned_data, something like: form.cleaned_data['extra'] = 'monkey butter!', then if the form.is_valid(), you have your extra info.
What you do finally will depend on what your extra information is, and where it is available to you.
There are a few ways to do this. One, is you can just add it to your template.
<form action="." method="post">{% csrf_token %}
{{ form.as_p }}
<input type="hidden" name="extra_field" value="{{ extra }}" />
<input type="submit" value="submit" />
</form>
Another way is to add the field to your form class, but use a hidden widget. I'm not sure if this is what you want. If it is, just add a comment and I can explain this point further.
