Not positive, but I don't think you can use null=True or blank=True on a forms.CharField(), you are passing null as a parameter to the init() of the forms.CharField and the interpreter is throwing this error. Try removing null=True from:

Change your forms to:

class UserForm(forms.Form ):
fname=forms.CharField(max_length=20)
lname=forms.CharField(max_length=20)
email = forms.EmailField()
address = forms.CharField(max_length=50)
country = forms.CharField(max_length=20)

Per the django site Django Form Fields, CharField has two optional arguments for validation: max_length and min_length, along with required.

Form fields don't have null or blank arguments. Those are for model fields only. For form fields, you just have required.

However, you should really be using a ModelForm which will create the form fields for you from the model, and allow you to save it afterwards.
