Smartif is great, I don't get why it's not a standard part of django
templates.

Adding errors

[CrabbyPete]

I want to return an error that a user was not found. I wanted to add
the error and have it formatted using errorlist as happens with a
required field. So I did the following

lform._errors['username']  = ErrorList("User does not exist or wrong
password")

The result in lform.errors is

ErrorDict: usernameUser does not exist or wrong password ...


instead of :
usernameUser does
not exist or wrong password

What am I doing wrong?

Complex query in model manager

[CrabbyPete]

I have the following code in model manager

class SpotMessageManager(models.Manager):

  def for_user(self, user, start = 0, end = None, friends ):
messages = self.filter(user = user).order_by
('date_added').reverse()
...

friends is a list of users, and I want the query set to include the
user and all the friends in the list. What is the best way to do this?

Re: save message text with registered character

[CrabbyPete]

Karen,

Sorry for the cryptic message.I just start using google groups and
django.  I was storing email that I received in a database. One of the
characters was a mark that could not be coverted for some reason. I
found the program decodeh.py and it fixed it for me.

Python noob tuples question

[CrabbyPete]

I am trying to make a selector in  a forms based on information in the
database.

The selector uses a tuple like this:

PEOPLE = (('john','adams'),('sam','smith'),('john','doe'), ...)

if I start a tuple with ( ('john","adams"))



if I start with PEOPLE = (('john','adams')) how do I add the
subsequent tuples?

I have tried  PEOPLE,('sam",smith) which works for the first one but
the next add gives me
 ((('john','adams'),('sam','smith')),('john','doe'))


If I do this PEOPLE += ('john','doe') I get a string
(('john','adams'),('sam','smith'),'john','doe' )

Could someone explain how I add tuples to tuples to get PEOPLE the way
its supposed to be.

Thanks

adding errors to forms

[CrabbyPete]

If I have a form and  if  form.is_valid is False

The code code in the template {{ form.name.errors}} formats the error
like this.
This field is required.

How do you add an error so it gets formatted with the surrounding
html. If a user name already exists I want to add the error message
'User name already in use'

I tried form._errors[name] = 'User name already in use' and
{{form.name.errors}} just prints the string.

Desperate Help needed. manage.py runserver no longer works.

I am new to django and I am running it on a Windows server. I
installed mod_wsgi with Apache and go it to work, but now when I run
python manage.py runserver. I get the error

Error: Could not import settings 'spot.settings' (Is it on sys.path?
Does it have syntax errors?): No module named settings
Exit code:  1

mysite is call spot. Can anyone tell me why running the django server
no longer works. I am going nuts trying to figure this out, and before
I rip out everything and start over can some please give me some
advise what to look for and what I might have gone wrong. I can only
assume it has something to do with what I did in my spot.wsgi file

import os
import sys

sys.stdout = sys.stderr

from os.path import abspath, dirname, join
from site import addsitedir

PROJECT_ROOT = abspath(join(dirname(__file__), "../"))

sys.path.insert(0, join(PROJECT_ROOT, "apps"))
sys.path.insert(0, abspath(join(dirname(__file__), "../../")))

from django.core.handlers.wsgi import WSGIHandler

os.environ["DJANGO_SETTINGS_MODULE"] = "spot.settings"

application = WSGIHandler()

Close window after download

[CrabbyPete]

I have code that generates a file for download. I want to close the
window after the user selects the download or even redirect them.

Here is my code:

response = HttpResponse(cal.as_string(), mimetype='text/calendar')
response['Content-Disposition'] = 'attachment; filename=schedule.ics'
return response

I can't close the window before the download using


 


because I get an error that the window closed.

So after the form download the window is hanging in limbo. If anyone
knows
how to close the window I'd appreciate it.

Thanks. The safe filter worked for me. I was writing it to a file and

fixtures and dates

I have a spreadsheet of football games that I wanted to get into an

required to put the date in -MM-DD format. So I changed it. The
problem is now when I run the admin and look at the game I get this
error

TemplateSyntaxError at /admin/football/game/
Caught TypeError while rendering: unsupported operand type(s) for +:

Any ideas why?

Re: Django in production on Windows

[CrabbyPete]

I'm not saying not to use IIS, I could just not get it to work. Other
people have asked how to get it work as well. Its not easy and I would
love to here from someone that was able to get it to work with IIS. I
developed everything on windows, and running Apache on windows was
great. No headaches and easy to debug if I ran into problems. I have a
friend who was a windows admin look at what I was doing with IIS and
he could not figure it out. If you know IIS and want to try it, I
would love to know how you made out with it.

Re: Fwd: Django in production on Windows

[CrabbyPete]

Windows is a great platform to work on. There are loads of tools and
support for Windows. The issue is not Windows vs Linux
the issue is Apache ( which works great on Windows ) v IIS. If your
admin is wants to use Windows by all means stick with it, and just
install Apache. I developed on Windows and deployed on both Windows
servers and Unix servers. Stay platform neutral and it won't matter.

Javascript Modal Window

I want to use greybox to show a login form. My question is what is the
best way to do this?

Login

Should I directly link to the form, or use {% url xxx %}, or is there
something else I should do?
Also can I send it back up if I get errors? Any advice much
appreciated.

Re: Javascript Modal Window

[CrabbyPete]

Thanks, but  I was not clear in my question. If I use jQuery or any
other javascript framework, to do a modal window from a link I have to
load some html code that is the form

Here is an example using thickbox in a template




login

In a view I load an html template with get_template()

Do I do this within the template as well?






get_template('mypage.html')

auto authenticate

[CrabbyPete]

I am connecting facebook to an app I have running. In order not to
change a load of code I created a dummy account when someone logs in
through facebook. My only problem is I want to authenticate with this
account when they log  Is there a way to login in a user using the
encrypted password. I am using pyfacebook and FacebookUser is the
following model


class FacebookUser(models.Model):
user= models.ForeignKey(User, unique = True)
fb_uid  = models.CharField( max_length=100, blank = True,
unique = True)

def __unicode__(self):
if self.user.username == u'':
return str(self.pk)
return self.user.username


the fb_uid is the Facebook id I get back. Here is my view when I get
called from facebook

fb = request.facebook
 try:
  fid = FacebookUser.objects.get(Q(fb_uid = fb.uid))
except FacebookUser.DoesNotExist:
   return ...

name = fid.user
pswd = fid.user.password
user = auth.authenticate(username=name, password=pswd)
 if user is not None and user.is_active:
 auth.login(request, user)


pswd is an encrypted password. Is there a way for me to authenticate
with it?

decorators

[CrabbyPete]

I am using pyfacebook and when I run the debug server I get the
following:

C:\Python26\lib\site-packages\facebook\djangofb\__init__.py:185:
DeprecationWarning: Calling the deprecated function 'new_wrapper'
Downgrade to decorator 2.3 if you want to use this functionality
  return decorator.new_wrapper(updated, f)

Can someone please explain this to me.

Thanks.

facebook email

[CrabbyPete]

I am fooling around with the facebook api. Facebook gives you a proxy
email address that is to big for the current User email field. Is
there a way to extend this field, or should I use another field
completely.

EmailMessage hangs in Windows

[CrabbyPete]

I am using
from django.core.mail   import  EmailMessage

and I have the following code
msg = EmailMessage ( subject   =  subject,
   body  =  body,
   from_email = sender,
   to  = receivers,
  bcc = bcc
)
try:
print "Mailing"
err = msg.send( fail_silently = False )
except Exception, e:
err = "Email Send Error " + str(e)
print err
else:
print "Mailed"

I am mailing a bunch of messages and every once in a while it hangs on
the send. I never know when, and it only happens with windows.

Any one else have this problem?

EmailMessage hangs in windows

[CrabbyPete]

I have the following code:

  msg = EmailMessage ( subject   = subject,
 body  = body,
 from_email = sender,
 to  = receivers,
 bcc= bcc
   )

try:
msg.send()
except Exception, e:
err = "Email Send Error " + str(e)
logger.error(self.log(err))
return False
   
return True

This works perfectly on my linux servers, but when I run it on windows it 
hangs, but not right away. Sometimes I can send 
4 five messages before it hangs.

Anyone have any idea what is going on?

Thanks

Model Inheritance and methods

[CrabbyPete]

I have the following models:

class Deal(models.Model):
"""
Deal is a deal for  Interest. There should only be one
deal for each Interest pair
"""
interest = models.ForeignKey( Interest )
max_sell = models.IntegerField(default = 1)

def terms(self):
return self.term_set.all()

class Term( models.Model ):
"""
A Term are the terms of a Deal. There can be many Terms for each
Deal
"""
deal  = models.ForeignKey( Deal )
canceled  = models.BooleanField(default = False)
cost  = models.CharField( max_length = 10, blank = True, null
= True )
buyer = models.ForeignKey( User, blank = True, null = True )

def execute(self, **kwargs):
pass

class Expire( Term ):
"""
Subclass of Term that is good until an expiration date
"""
date= models.DateField()

def execute(self):
if self.buyer == None or self.canceled:
return False

delta = self.date - date.today()
if delta.days >= 0:
return True
return False

def __unicode__(self, **kwargs):
return ''

class Cancel( Term ):
"""
Subclass of Term that the Term is good until canceled
"""
def execute(self):
if self.buyer == None or self.canceled:
return False
return True

def __unicode__(self):
return ''


I want to do the following:
for term in deal.terms()
 if term.execute():
do something


My thought was the term.execute method would be overridden and the
type of term, either cancel's or expire's execute method would occur,
but it only executes the term.execute()

I can get around it by having the following as the term execute, but
its ugly
def execute(self):
try:
   term.cancel.execute()
except:
   pass
try:
  term.expire.execute()
except:
   pass

Any suggestions?

This is what I suspected. Even though Django 1.3 is supposed to

Class Views

[CrabbyPete]

I have the following class defined

class TeamView(TemplateResponseMixin, View):
template_name = 'team.html'

def get(self, request):
if 'team' in request.GET:
team = Team.objects.get(id = request.GET['team'])
form = TeamForm(  )
else:
team = None
form = TeamForm()

return self.render_to_response({'form':form, 'team':team})

def post(self, request):
form = TeamForm(request.POST)

if not form.is_valid():
return self.render_to_reponse({'form': form})
...

When I call the self.render_to_response in the get it works fine, but
when I call it in the post
I get 'TeamView' object has no attribute 'render_to_reponse'

Any suggestions what I am doing wrong?

Class Views Questions

[CrabbyPete]

I am fooling around with django generic class views, and I was
wondering if its possible to actually build class views per item for
example I have the following class view.


class TeamView( View, TemplateResponseMixin ):
template_name = 'team.html'

def get(self, request):
if 'team' in request.GET:
team = Team.objects.get(id = request.GET['team'])
form = TeamForm( instance = team )
else
team = None
form = TeamForm( )

return self.render_to_response({'form':form})

def post(self, request):
form = TeamForm(request.POST)

if not form.is_valid():
return self.render_to_response({'form': form})



I want to use this class to also delete the team. I love to use a
method by itself by adding
   def delete(self,request)
   if 'team' in request.GET:
team = Team.objects.get(id = request.GET['team'])
team.delete()

Is there a way to specify this in url.py and get around the dispatch
for the get?

Any advise appreciated.

Re: Which Linux distro to use on EC2?

[CrabbyPete]

I've used Ubuntu 11.0 on an EC2 micro, using nginx and uwsgi and its
great. There is also a google group for ubuntu on ec2, with loads of
support. If you use uwsgi you have to compile it on the server. I had
a tough time using Amazons version, I don't remember why, but had no
problem using Ubuntu. Also make sure what version of python you wind
up with.

Automatically direct unauthenticated users to homepage

[CrabbyPete]

I have a site with lots of views. When someone comes to my site and is
not logged in I direct them to the homepage to login. However a user
could type in a whole url for a view and it will go there and cause an
error because the view expects the user to be logged in. I could put
logic in every view to see if the user is logged in but it seems
redundant. Is there a way to force anonymous users to the home even if
they type in a full url to a specific view

Re: Automatically direct unauthenticated users to homepage

[CrabbyPete]

Ivo,

Thank you. I was not using the @login_required decorator. I was using
generic classes like FormView and TemplateView but I see that in order
use login_required I have to put it in the url.py file and edit the
settings.LOGIN_URL to point to my login page.

Radio Choices and Generic Views

[CrabbyPete]

I use the following code that I got from a django snippet, which works
great if you want to have radio buttons with different types of fields
associated with them

from django import forms
from django.utils.encoding  import force_unicode

class ChoiceWithOtherRenderer(forms.RadioSelect.renderer):
def __init__(self, *args, **kwargs):
super(ChoiceWithOtherRenderer, self).__init__(*args, **kwargs)

def __iter__(self):
for inp in self.choices:
id = '%s_%s' % (self.attrs['id'], inp[0]) if 'id' in 
self.attrs
else ''
label_for = ' for="%s"' % id if id else ''
checked = '' if not force_unicode(inp[0]) == self.value 
else
'checked="true" '
html = ' %s %%s' %  \
(label_for, id, inp[0], self.name, checked, inp[1])

yield html

class ChoiceWithOtherWidget(forms.MultiWidget):
def __init__(self, choices):
widgets = [forms.RadioSelect(choices=choices,
renderer=ChoiceWithOtherRenderer),]
for choice in choices:
widgets.append(choice[2])

super(ChoiceWithOtherWidget, self).__init__(widgets)

def decompress(self, value):
if not value:
return [None, None]
return value

def format_output(self, rendered_widgets):
render = []
for widget in rendered_widgets[1:]:
render.append(widget)

render = tuple(render)
return rendered_widgets[0] %render

class ChoiceWithOtherField(forms.MultiValueField):
def __init__(self, *args, **kwargs):
fields = [

forms.ChoiceField(widget=forms.RadioSelect(renderer=ChoiceWithOtherRenderer),
*args, **kwargs),
]
widget = ChoiceWithOtherWidget(choices=kwargs['choices'])
kwargs.pop('choices')
self._was_required = kwargs.pop('required', True)
kwargs['required'] = False
super(ChoiceWithOtherField, self).__init__(widget=widget,
fields=fields, *args, **kwargs)

def compress(self, value):
if self._was_required and not value or value[0] in (None, ''):
raise 
forms.ValidationError(self.error_messages['required'])
if not value:
return [None, u'']
return (value[0], value[1] if force_unicode(value[0]) ==
force_unicode(self.fields[0].choices[-1][0]) else u'')


So in forms.py I create a form something like this.


BUDGET_CHOICES = [('Budget'   , 'Budget',forms.TextInput() ),
  ('No Budget', 'No Budget', forms.RadioSelect )
 ]


class PaymentForm(forms.Form):
budget  = ChoiceWithOtherField ( choices =
BUDGET_CHOICES )



This works great,  until I created a FormsView class

class Payment( FormView ):
template_name = 'leadb/lb_payment.html'
form_class= PaymentForm


def form_valid(self, form):
"""

then I got
Exception Type: ValueError
Exception Value:

too many values to unpack

Exception Location: C:\Python27\lib\site-packages\django-1.3.1-
py2.7.egg\django\forms\fields.py in valid_value, line 680

I am passing three choices and it expects 2. I am trying to figure out
how to get around this. Any advice appreciated.

Re: how django forms.ChoiceField with queryset ?

[CrabbyPete]

Do want to initialize a choice field? You can do this with forms

class SomeForm(forms.Form):


interest = forms.ChoiceField( choices=(),
 
widget=forms.Select(attrs={})
)

def __init__(self, *args, **kwargs):
super(SomeForm, self).__init__(*args, **kwargs)
self.fields['interest'].choices = [(i.interest,i.interest) for
i in Interest.objects.filter(status='standard')]

One from from multiple models using ModelForm

[CrabbyPete]

I wanted to combine two models into one form so I created the
following

class UserForm( ModelForm ):
class Meta:
model = User
fields = ('email','first_name','last_name')

class ProfileForm( ModelForm ):
class Meta:
model = Profile

class UserProfile ( UserForm, ProfileForm )
 class Meta( UserForm.Meta, ProfileForm.Meta)
  exclude = ('user',)

It only inherits UserForm

Is there a way to create one form using 2 modelform or to have
ProfileForm inherit from UserForm and add
Profile form data. Something like this

class ProfileForm( UserForm )
 class ( UserForm.Meta ):
  model = Profile

Re: Django E-Commerce Framework

[CrabbyPete]

Roll your own and use packages like django-authorize and django-paypal
they are easy to use and don't bring along lots of baggage.

Re: One from from multiple models using ModelForm

[CrabbyPete]

That is to bad. I have a project that I use mongodb and mongotools and
I can do the following with one form and it works great. I wonder if
any other form tools can do it

class UserForm ( MongoForm ):
class Meta:
document = User
fields = ('first_name','last_name')


class ProfileForm ( UserForm ):
class Meta(UserForm.Meta):
document = Profile

Re: Django E-Commerce Framework

[CrabbyPete]

There are lots of good payment packages you can use. I'm using this
one https://bitbucket.org/adroll/authorize/wiki/Home for CIM services
with Authorize.Net, but
there are lots of good packages you can use and its really very easy
to implement them. Satchmo is great, but if you really want to
understand and have controll roll your own.  I've also used
https://github.com/johnboxall/django-paypal and it really not hard at
all. I would also like to try this one https://github.com/abunsen/Paython

Iterable check boxes

According to the documentation I can iterate radio buttons

I want to do the same for checkboxes, but get

My field is

Show deactived radio button on a form

[CrabbyPete]

I have the following form:

DEAL_CHOICES = [
('Standard','Standard'),
('Sponsored','Sponsored'),
('Trial' ,'Trial')
   ]

class ApplyForm(forms.Form):

deal_type= forms.ChoiceField( required = True,

def __init__(self, *args, **kwargs):

If a trial is no longer available, I want to show it, but as a
deactivated choice. Can I do it, and is there a way to pass argument
to the init function to tell it to do so?

I tried ApplyForm( trial = False), but it causes the super(ApplyForm,
self).__init__(*args, **kwargs)
to blow up.

django uwsgi

[CrabbyPete]

I am trying to deploy a django project with nginx and uwsgi. I think I
have it all set up right but when I hit the site I get the following
error:

No module named project.urls

I know everything else is working because I still have debug on and
can see that settings.py is being read.
I know I'm forgetting something stupid but I can't figure it out so
any help appreciated.

Here is the wsgi.py file I am running:

import os
import sys

from os.path import abspath, dirname, join
from site import addsitedir

PROJECT_ROOT = abspath(dirname(__file__))

addsitedir(PROJECT_ROOT)
os.environ['DJANGO_SETTINGS_MODULE']='settings'

Thanks Shawn,
That is exactly what it is. I could have added one path up. I just
changed my

settings and it works fine.

Update a user profile after LInkedin Oauth

[CrabbyPete]

I am trying to update a user profile of an existing user with a
LinkedIn profile. My problem is I need an email address, but LinkedIn
does not give you that information. So I have a user create an account
with their email address and ask if they want to link their profile to
their LinkedIn profile. The problem is that the way Oauth works is
that it uses a call back and there is no way to link the user who
initiated the Oauth call to the call back coming from LinkedIn. If you
look at the request.user its Anonymous.

Does anyone have an idea how to get around this?

django-linkedin & oauth2

[CrabbyPete]

I took the code below from django-linked in which is code from
oauth2.  It works but does not do the callback.
How do you set the call back from oauth2

# from settings.py
consumer = oauth.Consumer(settings.LINKEDIN_TOKEN,
settings.LINKEDIN_SECRET)
client = oauth.Client(consumer)

request_token_url = 'https://api.linkedin.com/uas/oauth/requestToken'
access_token_url = 'https://api.linkedin.com/uas/oauth/accessToken'
authenticate_url = 'https://www.linkedin.com/uas/oauth/authenticate'

def oauth_login(request):
# Step 1. Get a request token from Provider.
resp, content = client.request(request_token_url, "GET")
if resp['status'] != '200':
raise Exception("Invalid response from Provider.")

# Step 2. Store the request token in a session for later use.
request.session['request_token'] = dict(cgi.parse_qsl(content))

# Step 3. Redirect the user to the authentication URL.
url = "%s?oauth_token=%s" % (authenticate_url,
request.session['request_token']['oauth_token'])

return HttpResponseRedirect(url)

save and restore session

[CrabbyPete]

I'm trying to access LinkedIn using Oauth. I don't want to log in with
it, just get user info from it. I'm using a call back which creates an
anonymous session on the callback. I want to save the session of the
user who initiated the callback. Is there a way to save a session and
then restore it back to the original user.

Re: django form radio input layout

[CrabbyPete]

I found a snippet that does what I want. 
http://djangosnippets.org/snippets/1377/

The documentation for it isn't great, and you have to edit it using
snippet 863 as a base.
His example does not work either but I got it to work like this

 terms   = ChoiceWithOtherField( choices = [ ('a','Until
Cancel', forms.RadioSelect),
 
('b','Until Date',   forms.DateInput),
 
('c','Until Count',  forms.TextInput)
   ] )

Re: Static Files on IIS7

[CrabbyPete]

Have you got django to run on II7 at all. I tried it and was not able
to get it to work. If you did I'd love to try it and see what comes up
with it.

Re: django & py2exe

[CrabbyPete]

I've been doing this with no problem here is the top of my routine
that runs on its own. After this just write what code you want to run

import os, sys
from os.pathimport abspath, dirname, join,split
from site import addsitedir

# Set up the environment to run on it own.
APP_ROOT, tail = split(abspath(dirname(__file__)))
PROJECT_ROOT, tail = split(APP_ROOT)

sys.path.insert(0,PROJECT_ROOT)
sys.path.insert(0,APP_ROOT)

from django.core.management import setup_environ

setup_environ(settings)

Re: Django, Apache, MySQL on Windows in Production

[CrabbyPete]

I've run django on Windows Server with apache and it was easy to
deploy.  Forget IIS. I've deployed Nginx and uWSGI on linux and that
was even easier.
I've never done Nginx on windows, but I don't think it would be a big
deal.

South

[CrabbyPete]

I've used South and I love it, but when I ran it for my latest
database I got this


C:\> manage.py migrate base

Running migrations for base:
 - Migrating forwards to 0001_initial.
 > base:0001_initial
 ! Error found during real run of migration! Aborting.

 ! Since you have a database that does not support running

 ! to leave it in an interim state between migrations.

! You *might* be able to recover with:   = DROP TABLE `base_profile`
CASCADE; []
...

 ! The South developers regret this has happened, and would

 ! easier-to-deal-with DBMS.
 ! NOTE: The error which caused the migration to fail is further up.

template newlines

[CrabbyPete]

I'm using the django template system for format a text email. I send
it a dictionary and it formats the output. The problem is that it
inserts lots of newlines

Here is the template, and reports is a dictionary that contains an
event and a dictionary of interests

Weekly Contact List For {{date}}
{% for event, interests in report.items %}
{% if interests|length > 0 %}
{{event}}
{% for interest, value in interests.items %}
{{ value }} {% if value == 1 %} lead {% else %} leads {%
endif %} for {{ interest }}
{% endfor %}
{% endif %}
{% endfor %}

Is there a way for it just to print the lines without adding all the
extra blank lines when interests = 0?

Re: template newlines

[CrabbyPete]

Even if there are no if interests|length > 0  I get the extra
whitespaces. Sam is correct. I've used Jinja2 before and used the - to
remove unnecessary lines.
I have lots of templates written for django, so I don't want to
retrofit them all. Worse case I could post process the message, but I
would love it if django support this feature in its template engine.

Re: django and eclipse

[CrabbyPete]

You have to set up the run environment. Make sure on run manage.py and
the parameters are runserver x.x.x.x:000 where x.x.x.x is the server
and :000 is the port you want to run from.  After that it should not
ask anything and run off your settings.

Facebook session problems.

[CrabbyPete]

I managed to log into facebook using the graph api, I store the FB id
and tie it to a User, like this

class FacebookUser(models.Model):
user= models.ForeignKey(User)
fb_uid  = models.CharField( max_length=100, blank = True,
unique = True )
access_token= models.CharField( max_length=100, blank = True,
null   = True )

def __unicode__(self):
if self.user.username == u'':
return str(self.pk)
return self.user.username

after I get the user I do the following:
user = auth.authenticate(username=user.username, password=password)
if user is not None and user.is_active:
auth.login(request, user)

I log in and all is good except I loose the session if I go to another
web site and come back.

Any help or advice greatly appreciated.

Re: Facebook session problems.

[CrabbyPete]

Its definitely a django thing. It does it on explorer as well. Somehow
the session information is lost. Maybe because it goes out to facebook
to get the log in. I used firebug and I can see the facebook cookies
as well as those for my site.

forms and models

[CrabbyPete]

I have the following code:
def sites(request):
if 'url' in request.GET:
url = request.GET['url']

website = WebSite.objects.get( url = url )
form = WebSiteForm(instance = website)

return submit_web_form( request, form )
else:
form = WebSiteForm(request.POST)
if not form.is_valid():
return submit_web_form(request, form)

   

It always come back invalid, and when if feed it back it displays the
error that "name" already exists.
I know it exist, but I want to edit the existing model. Do I have to
load in the data separately
like data = {'name':'blabla.com  and then form =
WebSiteForm( data ) or can I use the instance.

Re: How to reinstall Python Interpreters?

[CrabbyPete]

I wouldn't reinstall python because of an unresolved import error.
What's unresolved and what type of system are you on PC/Linux?

Re: How to reinstall Python Interpreters?

[CrabbyPete]

Why not just use virtualenv and then just easy_install

I'm using it with python 2.5 and it works great.
