As mentioned in my last entry on ModelForms, i was playing around with ModelForms in Django. I found something interesting in using both the get and post method.

I have 2 pages – one for forms. the other is to confirm values / pay. However, based on the last entry, I didnt really want to save the values in the form after i click submit.

to retract how the form looks like, here is it below:

def sample(request):
if request.method == “POST”:
form = SampleForm(request.POST)
if form.is_valid():
new_Sample = form.save(commit=False)
new_Sample.label = ‘Sample01′
new_Sample.save()
return HttpResponseRedirect(’/contact/thanks/’)
else:
print “no sell request”
form = SampleForm()
return render_to_response(’Sample.htm’, {’form’: form})

So, in order to change it to 2 pages. i changed the form page so it goes to the next page.

<form action=”sample2” method=”GET”>
<dl>
<dt><label for=”id_user”>user:</label>{% if user.errors %} <span class=”error”>{{ user.errors|join:”, ” }}</span>{% endif %}</dt>
<dd><input type=”text” name=”user” value=”{{ user }}” size=”6″></dd>
<dt><label for=”id_number”>number:</label>{% if number.errors %} <span class=”error”>{{ number.errors|join:”, ” }}</span>{% endif %}</dt>
<dd>  <input type=”text” name=”number” value=”{{ number  }}” size=”6″></dd>
<dt><input type=”submit” value=”Submit” /></dt>

and the views is a simple printing of form

def sample(request):
print “no sell request”
form = SampleForm()
return render_to_response(’Sample.htm’, {’form’: form})

Thus, when click on the button submit: it goes to the next page where all the values in the form is sent there. the url should show something like localhost:8000/sample2/?user=weiyang&number=10

and then for sample 2

def sample2(request):
if request.method == “POST”:
form = SampleForm(request.POST)
if form.is_valid():
new_Sample = form.save(commit=False)
new_Sample.label = ‘Sample01′
new_Sample.save()
return HttpResponseRedirect(’/contact/thanks/’)
else:
print “no sell request”
form = SampleForm()
return render_to_response(’Sample2.htm’, {’form’: form})

and my sample2.htm is shown as

<form action=”.” method=”POST”>

<input type=”hidden” size=”10″ name=”user” value=”{{ user }}”  />
<input type=”hidden” size=”10″ name=”number” value=”{{ number }}”  />
…..posting of values to be seen….

</form>

hope this helps.
