How to display an error message during registration for duplicate user?

I know it's simple and I have tried searching extensively but nothing works :(

When i try this in my forms.py:

class RegistrationForm(forms.Form):
    email = forms.EmailField(unique = True, error_messages = {'unique':'Duplicate Error!')
    password = forms.CharField( widget = forms.PasswordInput(render_value = False), label = "Password")

I get an error saying: init() got an unexpected keyword argument: unique

I see people getting it to work easily but clearly I am missing something. how can I add a custom error message for user registration using the form and view code given above? I want to display the error message beside the username field just like the error message displayes when the field is left empty.

thank you.

Use the clean method on the form to validate this:

from django.contrib.auth.models import User

class RegistrationForm(forms.Form):
    email = forms.EmailField()
    password = forms.CharField( widget = forms.PasswordInput(render_value = False),label = "Password")

    def clean(self):

        if User.objects.filter(email=self.cleaned_data['email']).exists():
            msg = _(u'Duplicate Error!')
            self._errors['email'] = ErrorList([msg])
            del self.cleaned_data['email']
        return self.cleaned_data
