Question

models.py:

class Users(models.Model):
    username = models.CharField(max_length=255)
    slug = models.CharField(max_length=255, default='0')
    password = models.CharField(max_length=300)
    passwordrepeat = models.CharField('Repeat Password', max_length=300)
    password_token = models.CharField(max_length=300, default='0')
    email = models.CharField(max_length=255)
    email_verified = models.BooleanField(default=False)
    email_token = models.CharField(max_length=255)
    email_token_expiry = models.DateTimeField(auto_now_add=True)
    tos = models.BooleanField(default=False)
    active = models.BooleanField(default=False)
    last_login = models.DateTimeField(auto_now_add=True)
    last_action = models.DateTimeField(auto_now_add=True)
    is_admin = models.BooleanField(default=False)
    role = models.CharField(max_length=255, default='0')
    created = models.DateTimeField(auto_now_add=True)
    modified = models.DateTimeField(auto_now_add=True)

    def __unicode__(self):
        return self.username

class UsersModelForm(forms.ModelForm):
    class Meta:
        model = Users
        fields = ('username', 'password', 'passwordrepeat', 'email')
        widgets = {
            'password' : PasswordInput(),
            'passwordrepeat' : PasswordInput(),
        }

views.py:

def register(request):
    flag = True
    possible = '0123456789abcdefghijklmnopqrstuvwxyz'
    token = ''
    length = 10
    i = 0

    current_datetime = datetime.datetime.now()

    user = UsersModelForm()
    if request.method == 'POST':
        userf = UsersModelForm(request.POST)
        username = userf.data['username']
        password = userf.data['password']
        passwordrepeat = userf.data['passwordrepeat']
        email = userf.data['email']

        if password != passwordrepeat:
            flag = False
            passVariable = {'user':user, 'flag': False}
            return render_to_response('register.html', passVariable, context_instance=RequestContext(request))

        elif password == passwordrepeat:
            while i<10:
                temp = random.choice(possible)
                token = token + temp
                i=i+1

            userf.email_token = token
            userf.email_token_expiry = current_datetime + timedelta(1)
            userf.save()
            return HttpResponseRedirect('/')
    else:
        return render_to_response('register.html', {"user": user, 'flag': True}, context_instance=RequestContext(request))

In template:

<div id="id_div_register">
    <form action="/register" method="POST">{% csrf_token %}
        {{ user.as_p }}
        <input type=submit value="Submit" />
    </form>
</div>

This form creates a textbox ‘repeatpassword’ because of the field in models.py. I don’t want to have a field ‘repeatpassword’ in the mysql table field/column. But i need to compare ‘password’ with ‘repeatpassword’ in template. How can i do it?

I need ‘password’ and ‘repeatpassword’ in template to compare these two, but i don’t need a column/field ‘repeatpassword’ in blog_users mysql table. How can i do it? Is it possible to do it.

Your need a new field on the form which is cleaned to check the passwords match, then you can remove the password checks within your view and replace with form.is_valid(). Something like the following:

class UsersModelForm(forms.ModelForm):
    passwordrepeat = forms.PasswordInput()
    class Meta:
        model = Users

    def clean(self):
        cleaned_data = self.cleaned_data
        password = cleaned_data.get("password")
        passwordrepeat = cleaned_data.get("passwordrepeat")
        if password != passwordrepeat:
            raise forms.ValidationError("Passwords must match.")

        return cleaned_data
