Problem with staticfiles

[Andreas Kuhne]

Hi all,

I am trying to CachedStaticFilesStorage to work in our environment. I have
been able to configure all of the settings, and am able to copy all static
files (we have alot of them) to the correct location. However when the
postprocessing starts and the MD5 hashes are being calculated it fails with
an exception:
ValueError: The file
'extjs/resources/css/images/default/editor/tb-sprite.gif' could not be
found with .

This is because it is going through the css files trying to rewrite the url
parts to add the MD5 hash. I have looked in the CSS files and all of the
url calls are using relative paths, but it seems as though the rewrite
process is forgetting to add the "../" part. The path that is in the error
is a concatenation of the path where the CSS resides (extjs/resources/css)
and the url (../images/default/editor), but it seems that the ../ is being
omitted somehow. I have checked and tested the code for traversing the css
files in a python shell and it works there. But it fails both on my
development machine and the staging server.

Has anyone had the same issues and knows what to do?

Regards,

Andréas

Answering my own question: it seems that Djangoproject doesn't manage the 
login but just redirect to a Trac instance (code.djangoproject.com) which 
manage the login. So Trac is not really "integrated" into Djangoproject.

Form validation vs. DRY

[Roman Klesel]

Hello,

I'm programming a database front end. In many cases I want to
constrain the data written to the database. Therefore I implement some
checks either through real database constraints or trough some logic
in the model, so it will throw an exception when the constraints are
not met.

e.g.: unique constraint on a database column.

Now, when I write my form validation, I have to implement the same
logic again, since form validation takes place before a save() is even
considered. Like this:

>>> if form.is_valid():
>>>form.save()

Is there a better way to do it? Is there a good way to avoid this
duplicate logic?

Regards
  Roman

Re: Form validation vs. DRY

[Tomas Ehrlich]

Hi Roman,
you can use model validation
https://docs.djangoproject.com/en/dev/ref/models/instances/#validating-objects

It works similar to form validation. After, when you create ModelForm,
it will take validation rules from model.

All these validations should be called outside save()


Cheers,
  Tom

Re: Exception Value: Reverse for 'vote' with arguments '('',)' and keyword arguments '{}' not found.

[Pepsodent Cola]

I just double checked.  A month ago I followed the Django Polls tutorial to 
the point and all of the above worked.

But the second time I followed the Polls tutorial I used different Model 
names such as *"class Citizen_voice(models.Model)"* instead of the 
tutorials table name.

class Poll(models.Model):


Will my underscore table naming convention cause problems with *"Generic 
views"* usage?

Custom Authentication

[adroit . goose]

Hello,

I am a newbie to Django and would wish to know if it possible to use the 
authentication scheme(from django.contrib import auth) on a custom made 
'Company_user' table.
I don't want to use the default User object provided by Django admin as the 
fields in the custom table are different. How should I go about it?.

Thanks,
Goose.

django-simple-multitenant

[Nigel Legg]

I am building an app to, among other things, allow people to upload data
files and carry out various analyses online.  I would like each user to
only see the datafiles that they or members of their team (company,
research team, etc) have uploaded.
It seems that 
django-simple-multitenantwould
be appropriate for this.  Are there any problems in using this, or
other apps that would be easier to implement?

Re: Error when loading application server

[Tom Christie]

Hi Helio,

  Something somewhere is expecting an integer but receiving an empty string 
instead.
This could be the result of a missing component in the URL eg 
`http://example.com/users//`,
or a field in a JSON or form data request that's missing a value, eg:

{
  "score": ""
  ...
}

Hope that helps.

Are you trying to access the _data_ (in database) from project 1, or do
you want to reuse the model definition in project 2 (where project 2
would have its own data independent from project 1)?

I just tried setting an always function and that is called and I can
get my response. So I guess I'll go with that. But I wonder why the
success function is not called.

I changed everything related to Model "class Citizen_voice" back to "class

Don't understand why my detail.html template will only accept the variable

Writing Form Tests

[Cody Scott]

I am trying to extend the polls tutorial code to use a django form with tests.


I created this form, but ran into some issues when trying to test it. When 
looking up how to test it, I found this form from 
http://toastdriven.com/blog/2011/apr/17/guide-to-testing-in-django-2/ It also 
had tests.


When I try to run those tests on my form I get the error

"_VoteForm is not callable"

"AttributeError: '_VoteForm' object has no attribute 'instance'"


Which form is preferred? How can I write similar tests for _VoteForm

#my form

def vote_form_class(poll):
choices = [(i.id, _(i.choice_text)) for i in poll.choices.all()]

class _VoteForm(forms.Form):
vote = forms.ChoiceField(choices=choices, widget=forms.RadioSelect())

def save(self):
if not self.is_valid():
raise forms.ValidationError("Poll Form was not validated before 
.save()")

data = self.cleaned_data
choice_id = data['vote']
choice = Choice.objects.get(id=choice_id)
choice.record_vote()

return _VoteForm



#form with tests

class PollForm(forms.Form):
def __init__(self, *args, **kwargs):
# We require an ``instance`` parameter.
self.instance = kwargs.pop('instance')

# We call ``super`` (without the ``instance`` param) to finish
# off the setup.
super(PollForm, self).__init__(*args, **kwargs)

# We add on a ``choice`` field based on the instance we've got.
# This has to be done here (instead of declaratively) because the
# ``Poll`` instance will change from request to request.
self.fields['choice'] = 
forms.ModelChoiceField(queryset=Choice.objects.filter(poll=self.instance.pk), 
empty_label=None, widget=forms.RadioSelect)



def save(self):
if not self.is_valid():
raise forms.ValidationError("PollForm was not validated first 
before trying to call 'save'.")

choice = self.cleaned_data['choice']
choice.record_vote()
return choice




class PollFormTestCase(TestCase):
fixtures = ['polls_forms_testdata.json']

def setUp(self):
super(PollFormTestCase, self).setUp()
self.poll_1 = Poll.objects.get(pk=1)
self.poll_2 = Poll.objects.get(pk=2)

def test_init(self):
# Test successful init without data.
form = PollForm(instance=self.poll_1)
self.assertTrue(isinstance(form.instance, Poll))
self.assertEqual(form.instance.pk, self.poll_1.pk)
self.assertEqual([c for c in form.fields['choice'].choices], [(1, 
u'Yes'), (2, u'No')])

# Test successful init with data.
form = PollForm({'choice': 3}, instance=self.poll_2)
self.assertTrue(isinstance(form.instance, Poll))
self.assertEqual(form.instance.pk, self.poll_2.pk)
self.assertEqual([c for c in form.fields['choice'].choices], [(3, 
u'Alright.'), (4, u'Meh.'), (5, u'Not so good.')])

# Test a failed init without data.
self.assertRaises(KeyError, PollForm)

# Test a failed init with data.
self.assertRaises(KeyError, PollForm, {})

PyCon APAC CFP

[Ian Lewis]

Hey Django users!

I wanted to get the word out that we are accepting talks for this year's
PyCon APAC in Tokyo Japan. If you have ever wanted to visit Tokyo and you
have a Python topic you are passionate about then this is your chance!

The conference is formatted into 4 tracks, 2 Japanese and 2 English tracks.
We are especially looking for English speakers to give talks so be sure
submit a talk proposal. I was a bit late getting the word out to the U.S.
mailing lists so there is only a week left to submit proposals. Don't sit
on it!
http://apac-2013.pycon.jp/speakers/cfp.html

More info about PyCon APAC

The conference is being held on Sept. 14th-15th with tutorials on the 13th
and development sprints being held on the 16th. We are hoping to have up to
500 participants this year (PyCon JP sold out at 400 last year). George
Brandl (@birkenfeld) is our first keynote speaker. We have another really
exciting keynote speaker lined up.

You can find out more about the conference details on the about page:
http://apac-2013.pycon.jp/about/index.html

The conference venue is the Kogakuin University Shinjuku Campus in the
heart of Tokyo. Anyone coming to the conference won't be at a loss for
things to do :)
http://apac-2013.pycon.jp/venue/index.html

...Or if you would just like to come and participate we welcome that too!
Conference registration is currently open:

Early Bird Registration: http://connpass.com/event/2703/
Patron Sponsor Registration: http://connpass.com/event/2704/

Thanks! If anyone has questions I'll do my best to answer them.
Hope to see you in Tokyo!

pip+virtualenv[wrapper] is a pratice not something that will allow you to
build a skyrocket as-is, you can live without it.

The documentation is good, and overall ecosystem alive and active, what do
you need more ? They are several CMS and admin apps, blog solutions etc...
They are still improvements and stabilisation to be done on many (utility)
apps... Everything I want to say is that outside the django tutorial, and
anybooks you read, the best way to improve your skills it to [re]build
something...

Time to time, I think about writring a set of tutorial about a CMS or
Social Network from scratch, but experience says that except the actual
code, the remaining issues are solved and well documented outside this
virtual project, so this would, I think, have little value.




HTH,

Amirouche

Re: Returning data from view to ajax call

[C. Kirby]

An HttpResponse includes http headers and will blow up an ajax call.
You want to use a render_to_string method and pass either json or a 
rendered template (render to string bypasses the headers, render to 
response will include them)

I don't want to return a template, just some data. I tried this:

return render_to_string(simplejson.dumps(data))

But it blows up with template not found.

Re: Returning data from view to ajax call

[C. Kirby]

I'm sorry, I was typing without thinking.
render_to_string() if you want to use a template without headers
render_to_response() includes headers

HttpResponse(json.dumps(data_object)) should be what you want.

It would also be helpful to see the code for your view. It looks like you 
already put the template code concerning the ajax call in this thread.

The view is very simple. It does some stuff and ends up with a single
short string that I am returning like this:

return HttpResponse(data, content_type="application/json", status=200)

I can pick up the string in an always function from data.responseText
so I'm going to go with that, declare victory and move on. Thanks to
everyone for the help.

Inserting String from Visual Basic Express 2010 to Django SQLite3 Database

[hiQ]

I've been able to configure my Visual Basic Express 2010 to read strings 
from certain measurement equipment. I also found a very cool youtube video 
(http://youtu.be/Z3j-7309ITc ) which shows how data can be added to 
Microsoft SQL table. Problem is I am stubborn and refuse to use Microsoft 
proprietary stuff that's going to screw me over in 2-3 years with a 
re-write.

Can this be done using Visual Studio Express 2010 and the SQLite3 table 
which Django uses?

Currently I can read and display the string information within the VB 
application. My end goal is to:

1. Read the string (which is currently working OK)
2. Write the string into the SQL table (which I have no idea how to do)
3. Plot the data line using Django Chartit (Also have no idea how to do)

Thanks for any guidance or references.

django create_without_commit method

[surya]

We just found a small bug regarding Django Transactions.
Our code were using objects.create_without_commit() method!!

I just added missing Transactions middleware and it all seems to work 
amazing now without actually editing the way models work..
Is this a known method? used in transactions and previous developer just 
forgot to add middleware?

He used django 1.3 (but our site seems to work perfect on 1.4 too)

Advice on creating an SFTP frontend in Django

[Paul Hudson]

Hi,

I have successfully used django-storages (
http://django-storages.readthedocs.org/en/latest/index.html)  and paramiko 
directly to log into an SFTP server and list a directory.  My end goal is 
to make a simple Client Area that allows the downloading of files hosted on 
SFTP.  I am open to any advice.  But here are a few specific questions:


   1. How should I handle authentication?  Use django's built in 
   authentication and pass the usr/pwd onto the SFTP? (is that possible in a 
   secure way?)  Authenticate directly against SFTP server in a secure way?
   2. Are files going to be transferred twice?  Once from SFTP to temp area 
   on Django server.  And then downloaded via client's web browser...  Am I 
   just better off hosting the files on the web server to begin with?  (The 
   files need to be available on SFTP and via web browser.  Maybe instead of 
   direct access to SFTP via Django, I should focus on a simple way to post 
   the original files to both places???)
   3. Are they any Django Projects/Plugins/Components for File Explorer/FTP 
   Client type GUIs that you would recommend using or referencing?



Thanks for any and all input!
-Paul

Does django have something similar to resource in rails?

I just started learning django. I was a rails developer before that. I was 
wondering if there is anything similar to resource in rails in django? Or 
do I have to make different urls and corresponding views for those urls? 
Thanks in advance!

Re: ANN: django-otp and friends: one-time passwords and trusted agents

[Peter Sagerson]

I took part of this conversation offline to spare the list from the gory 
details, but the upshot was that verifying an OTP is logically a mutating 
operation on the verifying device, and thus is not really valid on an unsaved 
model object. I posted an update to the documentation to clarify.

There were a couple of other questions down there that got lost, but they're 
more interesting to Django in general. Managing a heterogenous collection of 
model objects is indeed a little tricky, although it's definitely a solved 
problem: this is precisely what the admin interface does. Technically, it 
should be easy to derive an AdminSite that allows a user to manage their own 
devices, although integrating that cleanly into a broader site design is 
probably more trouble than it's worth. I suspect that your approach using 
ContentTypes is a good one--that's pretty much what they're for.

When I first embarked on this project, I actually thought that device 
management was one of the primary goals. Initially, writing a plugin required 
not just a model class, but a collection of forms that could be used to create 
and manage that device. Eventually I decided that there were several good 
reasons not to go down this road. To take one example, a TOTPDevice is fairly 
generic and could be paired with any number of real-world provers. Google 
Authenticator is the main one I know about, but there are others out there and 
more will emerge. Each prover may have a unique setup flow with different 
required TOTP parameters, some of which can't be anticipated in advance. For 
that reason alone, I think that integrating any kind of management UI directly 
into the device definition is a dangerous layer violation.

I'll back up for a minute and point out that--true to the open-source 
ethic--one reason I haven't published any generic device management code is 
that I haven't myself needed it. I currently have django-otp deployed in two 
places. One is only for internal users ("staff" in Django parlance), so it just 
uses the management interface. The other is targeted at competent but not 
necessarily technical users, so it's fairly directed. For example, I require 
that these users register and confirm an SMS device before I issue backup codes 
and a Google Authenticator key. This all uses device-specific UI, so no need to 
be generic.

This gets at the larger issue, which is designing policies for two-factor 
authentication. The policy that you're proposing is essentially to support as 
many kinds of OTP devices as you can and let users manage their own security. I 
think that model has a lot of merits and I'd be happy to see more sites adopt 
it where appropriate. Of course, the downside to being too casual about 
two-factor policies is account recovery. I recently read an article in which 
Google cited this as their Achilles heel in their push for two-factor 
everywhere. Hence the not-uncommon policy of requiring an SMS backup before 
allowing more volatile options.

What this all comes down to is that I think there's plenty of room for code 
that facilitates different kinds of two-factor authentication policies in 
Django apps. django-otp itself shouldn't include any of them, of course, 
because it's just the framework that provides the underlying mechanisms. I can 
easily imagine a django-otp-authenticator app which has tools for generating 
Google-Authenticator-compatible TOTPDevice objects, rendering QR codes, 
confirming, etc. Or, at a higher level, django-otp-devices, with views that 
allow a user to manage their own heterogenous collection of devices. The 
problem space is quite large and I'm not sure how it all shakes out in the end.

On the decorator question, it occurred to me that I actually use the 
otp-required-if-configured pattern as well, although I had it implemented 
directly in a view hierarchy. There seems to be a bit of incoherence in recent 
Django versions between the decorated-view pattern and the view-as-class 
pattern. In any case, I expanded the otp_required decorator to take an 
if_configured argument. New versions of django-otp and django-otp-agents are 
available.

Thanks so much for your feedback. Do keep in touch either here or privately to 
let me know how it works out.

Peter

Re: Advice on creating an SFTP frontend in Django

Hi Paul,

does all users have/need their own SFTP account on server?
If not, You can mount remote SFTP folder on web server and control access
to folders via django.

I do intend to look into this. I am sure it has (and is being) done plenty

Re: Exception Value: Reverse for 'vote' with arguments '('',)' and keyword arguments '{}' not found.

[Pepsodent Cola]

I think I know what the problem is with the Django 1.5 tutorial.
https://docs.djangoproject.com/en/1.5/intro/tutorial04/#amend-views

Both these classes are missing the "context_object_name" thingy, which 
links to the templates.

class DetailView(generic.DetailView):
class ResultsView(generic.DetailView):
model = Birdy
template_name = 'polls/detail.html'
template_name = 'polls/results.html'
*context_object_name = 'poll'*

Now my Poll application is working without having to use Poll as Model. 
 Also it's now working using the "Generic views".

[ Problem solved... ]

Re: django-simple-multitenant

[Mario Gudelj]

Depends what you need. Do you want to have users access data via
www.domain.com/user_acccount/ or http://user_account.domain.com? If it's
www.domain.com/user_acccount/ just foreign key your models to user model
and in your queries always include user as a filter. The other option is
somewhat harder.

Cheers,

_M

Django 1.5 runserver hangs in Chrome

[Nikolas Stevenson-Molnar]

I've just updated to Django 1.5 and am running into a problem when using
Chrome with the Django devlopment server (and staticfiles). One
particular page which loads a lot of static content /consistently/ hangs
in Chrome (works fine in Firefox). This seems similar to two resolved
issues: https://code.djangoproject.com/ticket/16099 and
https://code.djangoproject.com/ticket/18336. Except that I've waited
several minutes and the resources haven't finished loading. I've
increased request_queue_size as suggested in the second issue (first to
10, then 20, then 50) with no change.

I'd chalk this up entirely as a Chrome problem, except that if I switch
back to Django 1.4 (changing nothing else), everything goes back to
working fine. So what changed about runserver in Django 1.5 that might
cause this? And more importantly, how do I get around it? I'm running
everything on Windows 7 with Django 1.5.1 and the latest version of Chrome.

Thanks,
_Nik

Re: Django 1.5 runserver hangs in Chrome

[Nikolas Stevenson-Molnar]

Also, while Chrome is spinning, I can open Firefox and load pages
(including the problem page) just fine. So it's not that the server is
overloaded or anything like that...

Re: Python Fabric manage.py problem

[Roger Barnes]

It looks like you may be missing a space after the word "source".

My fabfile has these helpers, given an env.virtualenv and env.app_dir 
setting...

def ve_run(command, func=run, base_dir=None, *args, **kwargs):

base_dir = base_dir or env.app_dirwith cd(base_dir):with 
prefix("source /opt/virtualenvs/%s/bin/activate" % env.virtualenv):
return func(command, *args, **kwargs)


def manage(*args):return ve_run("python manage.py " + ' '.join(args))


I've had problems with custom settings (with Django 1.3 FWIW) which meant I had 
to use django-admin.py, so if the above doesn't work, this might:


def manage(*args):
return _ve_run("django-admin.py " + ' '.join(args) + " --pythonpath . 
--settings %s%s" % (env.settings,))


Hope that helps,

- Roger

Django admin automatically adding slash to a URL field after update

[ecasbas]

Hi,

I have this issue wit the admin interface:

I try edit manually a register, I change some values and when I save the 
data, the URL field, which I have no modifed, 
become automatically with a slash append at the end. This issue is causing 
inconsistencies due to I normalize each
URL before save to BBDD, but when I modify manually some register, then the 
problem.

I tried the advice from: 
https://docs.djangoproject.com/en/dev/ref/middleware/
APPEND_SLASH = False

but without success, any hints?

TIA
Emilio

Re: django-simple-multitenant

[Nigel Legg]

Mario, I am not sure what you mean here.  I want users to be able to upload
data to the site, and do various things with it. I want each user to only
see the data they have uploaded.  Whether this is domain.com/uer_account or
user_account.domain.com I don't know, so long as it provides the
functionality I need. If I use the domain,com/user_account, can I do that
with the standard django auth system?
