  • we only want to have this field when the form is being filled out by an anonymous visitor, and not when it’s coming from an authenticated user of the site
  • self.fields['captcha'] = CaptchaField()
  • if you wanted to change the max_length of a CharField, for example, you could simply pull it out of self.fields and make the changes you wanted.
  • Of course, there are limits to what’s practical to do in an overridden __init__(); sooner or later the amount of code required (and the gymnastics you’ll hve to do for things like custom validation methods) simply gets to be too much and you find yourself needing something a little more powerful. Typically, the solution for those cases is a factory function (or factory method, if you prefer) which knows how to build form classes.
  • how to build a form for it, minus the User field.
  • profile_mod = get_profile_model()  class _ProfileForm(forms.ModelForm):  class Meta:  model = profile_mod  exclude = ('user',) # User will be filled in by the view.  return _ProfileForm
  • form_class = utils.get_profile_form() if request.method == 'POST':  form = form_class(data=request.POST, files=request.FILES)  if form.is_valid():  # Standard form-handling behavior goes here...

  • The type() function takes three arguments: 

     
     
    1.   The name you want to give to your class. 
     
    2.   A list of one or more classes it will inherit from, in order. 
     
    3.   A dictionary whose keys and values will end up as the basic attributes of the class.
  • def make_contact_form(user):  # The basic form  class _ContactForm(forms.Form):  name = forms.CharField(max_length=50)  email = forms.EmailField()  message = forms.CharField(widget=forms.Textarea)  if user.is_authenticated():  return _ContactForm  class _CaptchaContactForm(_ContactForm):  captcha = CaptchaField()  return _CaptchaContactForm
  • But this is pretty ugly; let’s see how it works using type():
  • def make_contact_form(user):  fields = { 'name': forms.CharField(max_length=50),  'email': forms.EmailField(),  'message': forms.CharField(widget=forms.Textarea) }  if not user.is_authenticated:  fields['captcha'] = CaptchaField()  return type('ContactForm', [forms.BaseForm], { 'base_fields': fields })
  • use django.forms.BaseForm instead of django.forms.Form

  A useful little tutorial from James Bennett on how to produce dynamic forms with Django. Some of these techniques I have been using on my own, but he provides examples that show a much more efficient way of doing it than I have in my own code.
