Django Forms Help needed

Question

Hi All, Im new to django and trying to make a user registration form with few validations. Apart from this I also want a username suggestion code which will tell the user if the username he is trying to register is available or already in use. Then it should give few suggestions that might be available to choose from. Can anyone who might have worked on the same or somewhat same project help me with this.

Thanks

Check out the django-registration application. And have a look at the Class registration.forms.RegistrationForm and their method clean_username.

It should be easy to extend the form to suggest some usernames.

here is some sample code to generate unique username with numbered postfixes:

    username # filled with user input or first/lastname etc.

    #check for other profile with equal names (and those with a postfix)
    others = [int(username.replace(name, "0")) 
              for p in User.objects.filter(username__startswith=username).exclude(user=self.user)
              if username.replace(name, "0").isdigit()]

    #do we need a postfix
    if len(others) > 0 and 0 in others:
        username = "%s%d" % (username, max(others) + 1)

you could fill the generated names in a Form Choice Field: http://docs.djangoproject.com/en/dev/ref/forms/fields/#choicefield
