Re: Need help with my Form.save() method. Trouble with ForeignKey and ManyToMany Fields.

2010-08-05 Thread strayhand
Yep. I used Firebug to look at the HTTP information and "username" is
in there. Here's what firebug shows:

Parametersapplication/x-www-form-urlencoded
address P.O. Box 56868
areas   1
birth_date  1979-10-09
cityPuyallup
country USA
csrfmiddlewaretoken 0258a209df8a7df0ccca24ce789a448e
email   someem...@hotmail.com

password1   1234
password2   1234
phone   253-555-555
state_province  WA
usernametobybeal
zip_code98379

I believe that the problem isn't with the form creation or submission
but with my save method. The error seems to be specific to the way in
which I'm trying to create a new user. Here's my save method from the
form again.

# Taken from registration.forms.py

def save(self):

# User
new_user =
User.objects.create_user(username=self.cleaned_data['username'],
email=self.cleaned_data['email'],
password=self.cleaned_data['password1'])
new_user.first_name = self.cleaned_data['first_name']
new_user.last_name = self.cleaned_data['last_name']
new_user.is_active = True
new_user.save()

# Profile
new_profile = UserProfile.objects.create()
new_profile.user =
User.objects.get(username__exact=self.cleaned_data['username'])
new_profile.phone = self.cleaned_data['phone']
new_profile.address = self.cleaned_data['address']
new_profile.city = self.cleaned_data['city']
new_profile.state_province =
self.cleaned_data['state_province']
new_profile.country = self.cleaned_data['country']
new_profile.zip_code = self.cleaned_data['zip_code']
new_profile.birth_date =
self.cleaned_data['birth_date']
new_profile.areas = self.cleaned_data['areas']
new_profile.save()

return

What should I be doing differently with this snippet?

new_user =
User.objects.create_user(username=self.cleaned_data['username'],
email=self.cleaned_data['email'],
password=self.cleaned_data['password1'])

Thanks.

Need help with my Form.save() method. Trouble with ForeignKey and ManyToMany Fields.

2010-08-04 Thread strayhand
So I'm rolling out my own registration form that should update the
following models:

- User (auth module)
- UserProfile

Everything seems to be coming together but I'm having a hard time with
the save() method for the form. My UserProfile model has a couple of
fields that refer to other models and I'm having difficulty setting
them up properly. I keep getting an error telling me:

Exception Type: IntegrityError at /registration/
Exception Value: auth_user.username may not be NULL

I know where the problems are:

new_user =
User.objects.create_user(username=self.cleaned_data['username'],
email=self.cleaned_data['email'],
password=self.cleaned_data['password1'])

and I'm getting this similar error for defining the user profile on
the line below.

new_profile.user =
User.objects.get(username__exact=self.cleaned_data['username'])

I'm just not sure how else to write this stuff. I'm including my form,
model and the exact error message that I'm getting below. Any insight
that you have is greatly appreciated. Thank you.

Sweet. That did the trick. I found an example here:

# Areas Model UPDATED
from django.db import models

# Create your models here.
class Area(models.Model):
name = models.CharField(max_length=40)
city = models.CharField(max_length=50)
phone = models.CharField(max_length=12)
email = models.EmailField()

def __unicode__(self):

Ah... Well that's exactly what's happening. I'm getting "Area Object"
for each element in the select box. I've seen the __unicode__ method
on a few model examples, but my book and other resources never really
showed or explained it. I'll see if I can find some explanation of it.
Thanks for the clue.

How do I populate a multi-select field with a single column from a model?

Re: User Registration: Looking for tips

2010-07-29 Thread strayhand
Euan,

Thank you for the response. I agree with what you're saying and it
seems that I have two options before me.

1. Define simple form class for my registration process. Write a save
method that posts to both the "User" model and the "UserProfile"
model.

I could start this process from scratch but I came across this post
that I'm interested in. Have you by chance looked at any of the work
James Bennett (http://www.b-list.org/) has done with registration? He
has essentially taken the UserCreationForm as a guide and reworked it
to save the form to two models. In this example he's storing
activation key in the UserProfile model.

http://www.b-list.org/weblog/2006/sep/02/django-tips-user-registration/

I think that I could use what he's demonstrating here and add my own
fields. What are your thoughts on this code? There are a few comments
below his post that I'll need to keep in mind. My main concern is how
old the post is. I don't want to waste a lot of time with this
approach only to find out that Django has gone in a different
direction.

2. The second option would be to try the django-registration module
and make some tweaks.

Do you (or anyone else out there) have any experience with this
module?

http://bitbucket.org/ubernostrum/django-registration/overview

Seems like this would get me up and running with a registration system
a little more advanced than I currently have but it would still need
to be tweaked to include all of my profile fields. Here's a blog post
about tweaking the django-registration form by extending the class:

http://dewful.com/?p=70

Please let me know if you guys have opinions one way or another about
these two approaches. Thank you.

User Registration: Looking for tips

2010-07-28 Thread strayhand
I'm using the auth module for my project and I've got a registration
form that's based on the "UserCreationForm" provided by
"django.contrib.auth.forms" but it's only showing the username and
password fields.

I want a registration process that requires users to fill out ALL of
the "User" fields plus the fields in my "UserProfile" model.

If someone has some basic suggestions for how to modify the
UserCreationForm to include these additional fields I'm all ears. I
managed to find some basic examples of how to hide certain ModelForm
fields or change their labels but nothing about adding additional
fields, particularly from other models.

In addition to modifying the UserCreationForm I've come across a
couple of leads:

1. Build my own registration process following this example:

http://www.b-list.org/weblog/2006/sep/02/django-tips-user-registration/

I'm concerned with how old this post is. Is this approach still valid
given that it was posted in 2006? The author is using both the User
model and his own UserProfile model. I think that I could adapt this
for my purpose.

2. Use the django-registration package provided by the same author

http://bitbucket.org/ubernostrum/django-registration/overview

I'm concerned with having to install additional packages into Django.
It seems like this will make deploying my application on a Web host
more difficult. Can anyone speak to this?

Newbie Question: Syntax Error - Form Class, trying to set e-mail field to required=False

2010-07-22 Thread strayhand
I apologize in advance if i'm posting this question in the wrong area.
I'm learning about django's form class in "The Definitive Guide To
Django" and for some reason that's beyond me I keep getting a syntax
error. I've been over my code a dozen times and I'm hoping that
someone can point me in the right direction.

(Taken from page 133-134)

contactforms.py

from django import forms

class ContactForm(forms.Form):
subject = forms.CharField()
e-mail = forms.EmailField(required=False)
message = forms.CharField()

When I jump into the shell and type the following I get the syntax
error:

from contactforms import ContactForms
Traceback (most recent call last):
  File "", line 1, in 
  File "/Users/bealtr/Personal/YLBBQ/Django Projects/ylbbq/
contactforms.py", line 5
e-mail = forms.EmailField(required=False)
SyntaxError: can't assign to operator

What am I doing wrong?
