Yes, I agree, but the main point (for what I need) is also the display of the
date and times.

This will allow to keep the webapp forms/tables uniform (it's a
requirement) and also ease the use of javascript widgets for the date
and time fields (one format, coherent).

Problem with accents when filter

[Neto]

I want to filter results with and without accents, but Django can not do 
it. 

In my database has the word "áéíóú", but when I do: 

People.objects.filter (name__icontains = 'aeiou') 


Returns nothing. Django how to return the result with and without accent? 
(I am using PostgreSQL and Django 1.7)

Re: AppRegistryNotReady error running fastcgi on IIS

[Shawn H]

I was, but it turns out that wasn't the issue. I asked the question on the 
pytools site (here ), thinking 
it was possible an issue with wfastcgi. It turns out it's not an issue with 
wfastcgi. It's that At 1.6, the recommended handler was 

django.core.handlers.wsgi.WSGIHandler()

At 1.7, it seems the correct handler is now

django.core.wsgi.get_wsgi_application()

which calls django.setup() directly.

As soon as I replaced my handler in my web.config file, the issue 
disappeared. As you can see at the issue on the pytools site, there is 
still plenty of confusion as to the proper way to use wfastcgi in a pure 
wsgi application, but at least I can run my application. Thanks.

Re: at django login my request.POST.get data are all empty, I struggle with what I missed there

[Collin Anderson]

Use a login view like this:
@sensitive_post_parameters('password')
def login_view(request):
form = LoginForm(initial={'email': request.order.email})
if request.POST.get('login'):
form = LoginForm(data=request.POST)
if form.is_valid():
if user.is_active:
auth.login(request, form.user)
return redirect('public:courselist')
else:
messages.error(request, "Ihr Account wurde deaktiviert. 
Bitte nehmen Sie Kontakt zu uns auf, wenn Sie Ihnen wieder aktivieren 
wollen.")
return redirect('userauth:login')
return render(request, 'userauth/login.html', {'form': form})


and add a clean() method to your form like this:
def clean(self):
if self.cleaned_data.get('username') and self.cleaned_data.get(
'password'):
self.user = authenticate(username=self.cleaned_data['username'], 
password=self.cleaned_data['password'])
if self.user is None:
raise forms.ValidationError('Please enter a correct 
username and password.')
elif not self.user.is_active:  # or leave this out and handle 
inactive case in your view above.
raise forms.ValidationError('This account is inactive.')
return self.cleaned_data

Re: Problem with populate script

[robert brook]

This was really not a core function of the application, so I wold not worry 
about it.

Just add the data to a csv page and import it into sql lite to get you 
going.


But I believe that you need to tell Python where the data base is located 
using the settings file

 import os
 os.environ['DJANGO_SETTINGS_MODULE']='settings'

Problem with populate script

[Daniel Grace]

I am trying to follow the tutorial at http://www.tangowithdjango.com/
I am stuck in section 5.8 where it shows how to create a script to populate 
the database.
I created a script called "populate.py" as shown (except I added brackets 
for the Python 3 print statements),
and saved it in the root directory for my project.
But when I run the script I get an error:

(landy) C:\landy\tango>populate.py
Starting Rango population script...
Traceback (most recent call last):
  File "C:\landy\tango\populate.py", line 59, in 
from rango.models import Category, Page
  File "C:\landy\tango\rango\models.py", line 1, in 
from django.db import models
ImportError: No module named 'django.db'

I tried placing the script in C:\landy\tango\tango and C:\landy\tango\rango 
directories but I get similar errors.

Is it a better approach to make the populate script into a manage command?
Or should I be using fixtures?

Thanks

Force date and time formats to ISO

[Mark Caglienzi]

Hello to the list,
I am developing a Django website that needs USE_L10N = True, and
per-user TZ settings, but I want to force the output of dates and times
to ISO everywhere, once and for all (-MM-DD and HH:MM:SS).

I understand that Django with USE_L10N = True overrides the output of
DateField, DateTimeField, TimeField to follow the locale format, but I
need the format of my choice everywhere.

For the output in templates I came to this solution: write a
templatefilter that does the localtime -> strftime steps, and it works.

But to be the definitive solution also form fields when doing CRUD on my
database objects must accept and show dates and datetimes in that format.

I'm thinking that I have to write custom form fields like
ISO_DateField(django.forms.DateField),
ISO_DateTimeField(django.forms.DateTimeField) and
ISO_TimeField(django.forms.TimeField) overriding their methods to do
what I need.

Is there a better way?

Thanks in advance,
Mark

Yes. A simple solution would be to use a symmetric encryption like simple-crypt 
to encrypt and decrypt your passwords using a key that you provide externally. 
Here's a quick example:

import simplecrypt

SECRET_KEY = 'my_secret_key' # Get this from a file, enter it manually or by 
other sufficiently secure means

# Example code to generate the encrypred password
my_password = 'super_secret'
my_encrypted_password = simplecrypt.encrypt(SECRET_KEY, text)

# This is what you put in settings.py
my_encrypted_password = 'KLJJ543#EURO%'
my_password = simplecrypt.decrypt(SECRET_KEY, my_encrypted_password)

I see configurable settings, like those in the settings module, as code 
settings, and those you would put in the DB as user customizable settings. The 
former are meant to be changed by developers and sys admins, and the latter by 
website users. In my opinion settings module changes are mostly related to 
staging or performance rather than user oriented. Apart from there are a number 
of interesting Django apps in Djangopackages [1] that allow you to put your 
settings in the DB.

this is the currently fashionable answer, but I haven't seen any
justification for it.  Unfortunately, the 12factors manifesto tells
the how, but very little of the why.

In my experience, environment variables are clumsy, fragile and a pain
to work with.

I guess a more balanced option would be to store somewhere else,
probably the database (although i'm not too opposed to VCS) with the
host-variable parts (or everything, who cares about a couple KB extra
storage?) as a set indexed by hostname, which is read from the
environment.

So is it possible to store encrypted database passwords in the Django 
settings (or local_settings) file?

Strictly speaking, configuration belongs in a configuration management system - 
Ansible, Chef and Puppet being just examples. The words option, setting, 
preference and configuration are often used interchangeably, but if you define 
"configuration" as "something that is loaded by the program on startup" and 
which is not universal for all installations, then you must store configuration 
independently from the VCS and DB.

Depending on your hosting environment, you could store your host-specific 
configuration in a versioned Fabric script. But keep in mind that storing 
cleartext passwords is bad practice, be it in a database or in Git.

Re: Newbie Question: Django Tutorial Part 4 - Exception Issue

[Daniel Rus Morales]

No, that’s not the cause, the lack of it would be. That line shows the content 
of ‘error_message' when it does exist and has a value other than None. But if 
you have it in your template the error must be somewhere else in your code. 
Must be a simple syntax mistake you didn’t notice, either in the template file 
or in the vote view.

To be sure that your code is raising an exception you can place a print 
statement right after the except, before the call to render. Replace the call 
to render with these lines, they do the same but also print a message in the 
console:

except (KeyError, Choice.DoesNotExist):
# redisplay the question voting form
context = {
'question': p,
'error_message': "You didn't select a choice.",
}
print("context: ", context)
return render(request, 'polls/detail.html', context)


Click vote again and see what’s the output when you click on “Vote” without 
selecting any choice. The text of the print statement will show up in the 
console where you launched `python manage.py runserver`.

If you see the output “context: “ and the ‘error_message’ string with the 
actual message, then you have a syntax mistake in your template. Otherwise it’s 
in your view.

Cheers

"To the environment"

A good practice is to place config in the environment[0] and load it from
code.

Config: DB or git?

[Thomas Güttler]

Hi,

of course we separate data from code:

 - code belongs into version control (git)
 - data belongs into a database (postgres)

But where does configuration belong?

Since I am a developer I like version control.

But the longer I think about this question, I think
the perfect configuration for an app just contains
one entry: How to connect to the DB.

Sooner or later you want things to editable via an admin interface.

And if you look at big systems like SAP. There is only very little config in 
files.

I think config should be done in the database, not files. It is hard to accept
this, since version control is great for files, and not so good for databases,
but I think it is the way to go.

What do you think?

  Thomas

Re: Change GFK to FK

[Tom Christie]

You'll probably want to take this approach:

* Create a schema migration, adding the FK.
* Create a data migration, populating the FK data.
* Create a schema migration, removing the GFK.

Looking for feedback on this Django news aggregation feed

[kvnflm]

I'm working on a prototype for a website that aggregates articles from 
various blogs around the web and tags them by the terms that are mentioned, 
so you can create a customized feed with articles related to topics you're 
interested in. If you'd like to check it out, you can see the Django feed 
here:

http://hakken.ubicast.com/feed/django

If anyone has any feedback on what features you like, don't like, or would 
like to have, as well as any sources on Django usage/development that 
aren't already present, that would be great to know.

Thanks!

Newbie Question: Django Tutorial Part 4 - Exception Issue

Hi,

I am following Django official tutorial and have unanswered issue at part 
4, https://docs.djangoproject.com/en/1.7/intro/tutorial04/. Here is the 
exception handling code,

except (KeyError, Choice.DoesNotExist):
# Redisplay the question voting form.
return render(request, 'polls/detail.html', {
'question': p,
'error_message': "You didn't select a choice.",
})

When I run the server and click on [Vote] without selecting a choice, the page 
does NOT show me the error message. The same voting page comes back as if 
[Vote] was not clicked.
I checked my lines and everything seems identical per tutorial.

Any help appreciated!
Thanks
