Re: Confirm email by matching on form

I have a form with an email field and email confirmation field.  I
want to check the form input to make sure the two fields match.  So
far I can get the error message 'Email addresses do not match.' to
display, but if they do match I am getting an error 'InterfaceError
at /order/
Error binding parameter 5 - probably unsupported type'  Here is my
code:

#models
from django.db import models
from django import forms
from django.forms import ModelForm

class Customer(models.Model):
       date_stamp = models.DateTimeField(auto_now_add=True)
       order_number = models.PositiveIntegerField(editable=False)
       first_name = models.CharField(max_length=30)
       last_name = models.CharField(max_length=40)
       email = models.EmailField()
       email_conf = models.EmailField(verbose_name='Confirm Email')
       year_built = models.PositiveIntegerField()
       period = models.PositiveIntegerField(editable=False)
       direction = models.CharField(max_length=20,
choices=direction_choices)
       floor_plan = models.CharField(max_length=2,
choices=floor_plan_choices)

       def __unicode__(self):
               return u'%s %s' % (self.first_name, self.last_name)

Not related to your problem, but storing two copies of the (verified to be the same) email address in the database seems odd.  I would leave email_conf out of the model and include it only in the form.

class CustomerForm(ModelForm):

       class Meta:
               model = Customer

       def clean_year_built(self):
               year = self.cleaned_data['year_built']
               if year < 1800:
                       raise forms.ValidationError("Please enter a year between 1800 and
2020.")
               if year > 2020:
                       raise forms.ValidationError("Please enter a year between 1800 and
2020.")
               return year

       def clean_email_conf(self):
               cleaned_data = self.cleaned_data
               email = cleaned_data.get("email")
               email_conf = cleaned_data.get("email_conf")
               if email and email_conf:
                       if email != email_conf:
                               raise forms.ValidationError("Email addresses do not match.")
               return cleaned_data

I'd guess the problem is here, where you are returning the entire cleaned_data array instead of just the data for the field you are cleaning.
