URLs..
What is URL?
URLs..
Maps your “view functions” to a URL.
● someone visits a URL● URL tells django what to do● Django returns a set of HTML (templates)
Templates [part 1]
Just HTML… take it EASY!
Templatesmysite
⇒ mysite
===> templates/mysite
===> [other folders]
⇒ app1
===> templates/app1
===> [other folders]
⇒ app2
===> templates/app2
===> [other folders]
forms [Non-model based]
● Create `forms.py` in your Django Application
● import the Form class
● define what you’ll collect
from django import forms
class MessageForm(forms.Form):
number = forms.CharField()
text = forms.CharField()
forms [Non-model based]
from form import MessageForm
def new_message(request):
form = MessageForm()
if request.method == “POST”:
form = MessageForm(request.POST)
if form.valid():
form.save() # save
else:
pass # handle errors!
return render_to_response(‘messages/new.html’, {‘form’:form}, RequestContext(request))
