Re: CSS reference to Media folder

[Leonardo Giordani]

I think it is better for you to keep CSS images in /static folder too.
/media is better suited as a folder to host user-loaded content.

If you keep CSS and images in /static you can just refer to them with
a relative path.

I think that probably (but I'm not sure) CSS can only address relative
paths from their location.

G+ API library

[Timothy Makobu]

Hi all,

Is there a completely bare bones script out there for G+?
Something that takes the client_id and client_secret and returns a handle
to G+; something like python-twitter?

connection.cursor()

[MikeKJ]

I got these imported tables from an external source so I need to
access the data using connection.

The problem I have is getting at the data in more than 1 table with
one dict the pure sql call would be something like

select * from yw_basics ywb left join yw_next ywn on ywb.id = ywn.id
where ywn.field = 0

def dictfetchall(cursor):
desc = cursor.description
return [
dict(zip([col[0] for col in desc], row))
for row in cursor.fetchall()
]

def secondhand(request):
from django.db import connection, transaction
cursor = connection.cursor()
cursor.execute("SELECT * from yw_basics")
stuff = dictfetchall(cursor)

I tried adding the sql call above into the cusor.execute and failed
miserably so any clues would be gratefully received.

Yes, that's correct. It's recommended to set
"FEINCMS_REVERSE_MONKEY_PATCH = False" as soon as possible
(especially in new projects.)

Btw, if we want to upgrade several (old) FeinCMS sites we are runnning this
will cause a lot of pain for us too. On the other hand we finally have explicit
instead of fragile behavior, so I think the pain is still worth it
(besides being
a better citizen in the Django ecosystem, because now we do not rely on any
monkey-patching of Django proper anymore.)

Well for now you don't NEED to change anything. You'll get those pesky 
deprecation warnings, but everything should continue to work fine for now, 
so there's no need to rush things, you can change your code as you go along.

Re: Creating a hospital erp (hospital management) in Django

[Saadat]

Hi all, I created a view today and I could access the database
contents using Templates. Now I wish to create a listbox that would
have the names of doctors. When an item from the list is selected, an
sql query should be sent which will return all the details of that
doctor, where doc_id is the primary key? how do we create buttons? do
we need to use html or django can handle them also?

Thanks a lot people.

Problem loading integer data into database using fixture

[Gchorn]

Hello All,

I'm attempting to provide initial data for my database using a fixture
file (like this: 
https://docs.djangoproject.com/en/1.3/howto/initial-data/#providing-initial-data-with-fixtures),
but I'm running into the following error:

Problem installing fixture '/home/guillaume/NBA/players/fixtures/
player_data.yaml': Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/django/core/management/
commands/loaddata.py", line 169, in handle
for obj in objects:
  File "/usr/local/lib/python2.7/dist-packages/django/core/serializers/
pyyaml.py", line 54, in Deserializer
for obj in PythonDeserializer(yaml.load(stream), **options):
  File "/usr/local/lib/python2.7/dist-packages/django/core/serializers/
python.py", line 122, in Deserializer
data[field.attname] =
field.rel.to._meta.get_field(field.rel.field_name).to_python(field_value)
  File "/usr/local/lib/python2.7/dist-packages/django/db/models/fields/
__init__.py", line 471, in to_python
raise exceptions.ValidationError(self.error_messages['invalid'])
ValidationError: [u'This value must be an integer.']

Here is a sample from the YAML fixture file I'm attempting to use:

- model: players.player
  pk: 2
  fields:
team: DEN
first_name: Arron
last_name: Afflalo
age: 26
pos:  SG
gp: 25
mp: 754
fg: 98
fga: 227
ft: 62
fta: 78
three_pointers: 31
threes_attempted: 81
orb: 15
drb: 51
ast: 39
stl: 15
blk: 6
tov: 33
pf: 55
pts: 289

Isn't what I have there mostly integers?  I've already checked my
models.py file to make sure I didn't accidentally use an
"IntegerField" for "team", "first_name", "last_name", or "pos."  Do I
need to include some other kind of formatting information in my YAML
file to indicate that the numbers are integers?

thanks,
Guillaume

Not necessarily - if there's no compound primary key, you can build
django models from the tables using manage.py inspectdb (be sure to
add the managed=False and set the correct tablename in the generated
model's Meta).

"select * " is usually a bad idea.

You'd be better using lazy evaluation:

def dictfetchall(cursor):
# avoid reexecuting constant code in a loop
desc = col[0] for col in cursor.description
for row in cursor:
yield dict(zip(desc, row))

First clue : "failed miserably" is about the most useless possible
description of the problem, specially if you hope to get any help. At
the very least explain what happens (and if you get an exception post
the full traceback).

Re: load settings on database

I just don't understand what "loading a table" is supposed to mean. If
you want to make some object (model instance or whatever) available to
all your templates, a context processor will do the job. If you want
to make it available to all your views, you can use a middleware and
attach the relevant object(s) to the request object.

Now given the name ("settingsuser") I suspect it's a kind of "per-user
settings" stuff. If so, the SettingsUser model should have a
foreignkey on User, and then you can just follow the reversed
relationship, ie:


# youmodels.py
class UserSetting(models.Model):
user = models.ForeignKey(User, related_name="settings")
parrot_is_dead = models.BooleanField(u"Is user's parrot dead ?",
default=True)


# yourviews.py


def something(request, *args, **kw):
print request.user.settings.all()

Model.delete() was not called.

[SomeoneToIgnore]

Hello. I'm using Django 1.3.1.

I've got some strange behaviour while deleting an object in admin
panel.

Here's the code from models.py:

class Poll(models.Model):
question = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')

def was_published_today(self):
return self.pub_date.date() == datetime.date.today()
was_published_today.short_description = 'Published today?'

def __unicode__(self):
return self.question

def delete(self, using=None):
print "Deleted"
super(Poll, self).delete(using)

It is just the code from django tutorial with delete() method
overriden.

There was an issue:
https://code.djangoproject.com/ticket/11022

If I open the object's properties page and delete an object using
Delete button on that page everything works fine and message displays
in the console.

But if I check the object's checkoxes (insted of opening their
property list pages), select "Delete selected polls" action and press
the Go button, the Delete multiple objects page opens.
Then I press "Yes, I'm sure button" and objects are successfully
deleted.

But their delete() method are not triggered so i don't get the message
"Deleted" in the console.
It does not matter if I choose one or multiply objects - the message
still does not appear in the console.

Should I consider this behaviour as a bug or I am doing something
wrong?

Thanks! Maybe I wasn't clear, I know this is not a django-specific

I've read about this, I'll give it a try!

The delete select action uses the queryset's delete method [1], which 
means the model's delete method is not called.


It's not a bug, the behaviour is documented on the admin actions page. [2]

Re: Django Location- Does anyone know about this?

[Addy Yeow]

Not exactly a Django package but it's implemented in Django and uses
MaxMind geoip database:
http://dazzlepod.com/ip/
You could use the API for free, e.g. http://dazzlepod.com/ip/8.8.8.8.json

Re: import problem

[Scott Macri]

DrBloodmoney I not sure what you mean by circular imports.  datetime
is the only import I have in this file.

Yes Furbeenator it is a 'datetime' is not defined error.

I'll post the entire error message tonight when I get home.

My website directory is mn and my app directory is hcp.  I'm trying to
do the import on a file in the hcp app directory.  The imports of my
classes (ie from mn.hcp import something) work just fine.  The issue
seems to be with python specific imports.

Thanks.

Sharing users db

[Evgenii Belykh]

Hi folks!

I've trying to use sharing db via technique proposed by Dustin at
http://dfcode.com/
(available at
http://webcache.googleusercontent.com/search?q=cache:ukYEYwoaJtYJ:dfcode.com/blog/2011/5/sharing-django-users-and-sessions-across-projects/+sharing+users+django&cd=1&hl=ru&ct=clnk&gl=ru&client=opera)


it works untill I've trying to exclude /admin from routing via the
following code:
import threading


# Object to hold request data
request_cfg = threading.local()


class RouterMiddleware(object):
"""
Sets a flag if we are accessing Django admin to prevent database
rerouting
for the auth model.  Removes the flag once the request has been
processed.
"""

def process_view(self, request, view_func, args, kwargs):
if request.path.startswith('/admin'):
request_cfg.admin = True

def process_response(self, request, response):
if hasattr(request_cfg, 'admin'):
del request_cfg.admin
--
Accessing site root get an error:
TypeError at /

argument of type 'NoneType' is not iterable
Exception Location: /home/alexey/sites/django/http/utils.py in
fix_location_header, line 19:
if 'Location' in response and request.get_host():
response['Location'] =
request.build_absolute_uri(response['Location'])
return response

-
Any help much appreciated.
PS.Maybe smth wrong in RouterMiddleware since it does not return a
response?

Asked and answered yourself!

Yes, that is exactly why it is failing. process_response(), if it
exists, must always return a response.

See:

https://docs.djangoproject.com/en/1.3/topics/http/middleware/#process-response

Re: Problem loading integer data into database using fixture

[Bill Freeman]

Well, I don't know yaml, but if you are in a place where you don't
have to quote:

   Arron

then I'd expect everything to be strings.

Is there a yaml.dump that you can apply to a model with strings and
integers to see how it thinks they are distinguished?

Help on forms.py

[Stanwin Siow]

Hello,

I'm trying to modify the default registration forms.py by adding in more fields.

Currently it's like that:

=
keyword_info = {
"queryset" : Keyword.objects.all(),
}

class RegistrationForm(forms.Form):
   
username = forms.RegexField(regex=r'^\w+$',
max_length=30,
widget=forms.TextInput(attrs=attrs_dict),
label=_(u'username'))
email = forms.EmailField(widget=forms.TextInput(attrs=dict(attrs_dict,
   maxlength=75)),
 label=_(u'email address'))
password1 = forms.CharField(widget=forms.PasswordInput(attrs=attrs_dict, 
render_value=False),
label=_(u'password'))
password2 = forms.CharField(widget=forms.PasswordInput(attrs=attrs_dict, 
render_value=False),
label=_(u'password (again)'))
keywords = forms.ChoiceField(choices=keyword_info)
label=_(u'keyword'))


=

The thing is i would like keywords to be a drop down menu of keywords which are 
derived from the keyword database table.

Can someone check if what i'm doing is correct?

Thank you!

Hi Stanwin,

Hello,

I'm trying to modify the default registration forms.py by adding in

Currently it's like that:

=
*keyword_info = {*
*"queryset" : Keyword.objects.all(),*
*}*

class RegistrationForm(forms.Form):

*keywords = forms.ChoiceField(choices=keyword_info)*
*label=_(u'keyword'))*


You're using a ChoiceField, which requires a list of 2-tuples, for example:

   choices = [('keyword1', 'keyword1'), ('keyword1', 'keyword1')]

What you probably want is a ModelChoiceField [1], which takes a queryset 
argument.


keywords = forms.ModelChoiceField(queryset=Keyword.objects.all())

Re: Django 1.4 beta 1 released

I just wanted to let you know that we have also released a new version
of BitNami DjangoStack 1.4b1 which bundles Django 1.4b1. I hope that
will make easier to test this new version without conflicting with
your current stable environment.

Re: import problem

[Scott Macri]

I don't believe I have any circular imports in my code.  I have a
simple file dosomething.py, with a simple class containing a simple
function.
dosomething.py
def somefunction(some_date)

At the tope of dosomething I have:
import datetime

in the somefunction def I have:
start_date = 
datetime.date(int(some_date[0:4]),int(some_date[5:7]),int(some_date[8:10]))

As soon as the code gets to the line containing start_date it fails.

Re: Problem loading integer data into database using fixture

[Gchorn]

Thanks very much for the reply.  I went ahead and created a model
instance using the API, and then tried to get a yaml dump of this.
However, I'm running into another (newb) problem.  The database I'm
using is under a different username (I'm doing all of this in Ubuntu
Linux 11.10), which I understood to be good practice.  However, when I
do a python manage.py shell I have to already be in one user name or
another.  The database username gives me access to the database
through the API, but then I can't create a data dump file because I
don't have file write access under that username.  I can't be under
both usernames at once can I?  Do I just need to give write-access to
the database username as well?  If so how do I do that (I know we're
veering away from Django here, sorry)?

Re: Problem loading integer data into database using fixture

[Bill Freeman]

The database user and *nix user are (typically) unrelated.  The
database user is specified in settings.py and there is also a password
if necessary.  Since one usually communicates with database servers
using network connections (even on the same box), it doesn't really
know what user a connection came from.

Unless you are using sqlite3 as your database, in which case you just
need to copy and change the ownership of the database file (may
require sudo).

Re: import problem

[Scott Macri]

WEIRD.  There must have been something messed up in my environment.  I
closed IDLE, deleted the dosomething.pyc file and reran the code.  It
seems to be working now.  I didn't make any code changes so maybe
something was in memory, who knows.  I tried deleting the pyc file
before and it didn't do anything.

Do I need to close IDLE every time I modify one of my object classes
being accessed?  I've just been recreating the object in IDLE and not
closing the window.  Any thoughts on this?  Thanks.

serving files on shared server cause extra proccesses

[Itai]

Hi all!

I have a big problem, and after reading tons of web pages I'm still
stuck.


IN SHORT:
I'm on a shared server hosting with fastCGI (=no apache access) with
no mod_xsendfile. I need to serve mp3 files of 2-3 minutes length
after authentication. That view generates extra proccesses that never
die, and maybe it timesout and creates new proccesses (???).


THE DETAILS:

My django app is on a share server, so I'm forced to use fastCGI. I
don't have access to apache settings.
Lately I've been having lots of proccesses named "/usr/bin/python
index.fcgi" that suddenly appeared and just stayed there forever.

After a lot of headache, I figured out their source was an HTML page
with JPlayer plugin (a JQuery plugin to play music - http://jplayer.org).
As the HTML page loads, Jplayer loads and calls my server with the URL
of the music file to play.
This request goes to this django view (needed for authentication of
request):

def serveMusicFile(request,filename):
my_auth_check(request)
from django.conf import settings
file = open('/my/private/file/location/'+filename)
response = HttpResponse(file.read(), mimetype="audio/mpeg")
response['Accept-Ranges'] = 'bytes'
response['Content-Length'] = os.path.getsize('/my/private/file/
location/'+filename)
response['Content-Disposition'] = 'filename='+filename
return response


So,
Why does the fastCGI create new threads for these music file
requests?
Why don't they die eventualy?
**What can I do??**

Thanks guys!

Access denied - hostname is percent character ('%')?

[Ishmael]

I'm trying to follow the intro tutorial.
I am able to log in to my database from the command line (and via
MySQL Workbench) sans problem:
However, after changing my settings file to the correct values, I get:

_mysql_exceptions.OperationalError: (1044, "Access denied for user
'myuser'@'%' to database 'Mydatabase'")

My settings file contains:

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', # Add
'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'Mydatabase',  # Or path to
database file if using sqlite3.
'USER': 'myuser',  # Not used with
sqlite3.
'PASSWORD': 'mypassword',  # Not used with
sqlite3.
'HOST': 'my.url.com',  # Set to empty
string for localhost. Not used with sqlite3.
'PORT': '3306',  # Set to empty string for
default. Not used with sqlite3.
}
}

How do I get rid of the '%' percent symbol for the local hostname?

Thanks for your help!

"DatabaseError: can't adapt type 'NavigableString'" when using psycopg2 and Django 1.3

[Matt Cotterell]

Hi guys! New poster here and django newbie, though I'm starting to get
a handle on it now.

One issue though which is preventing release of my project is a truely
bizarre bug pertaining *purely* to postgres. I'm running Django
(1.3.1) with psycopg2 (2.2.1) and despite everything working on the
development 'runserver' server using SQLite, at some point during this
project the 'production' server running on mod_python no longer works.

The fault specifically pertains to a custom authentication module
which gets XML data over an HTTP call with pycurl. When logged in as a
regular 'ModelBackend' user, everything works fine. However when
trying to create a new User object as such:

...
except User.DoesNotExist:
# Create a new user. Note that setting the password really doesn't
mean anything.
user = User(
username=username,
email=username,
password='',
first_name=user_firstname,
last_name=user_lastname
)
user.save()
...

...I get the following Exception when calling save():

Exception Type: DatabaseError
Exception Value: can't adapt type 'NavigableString'
(traceback: http://dpaste.com/704253/)

The local variables at the time of exception are:

username:   u'matt...@example.com'
c: 
password: u'x'
user_firstname: u'Matthew'
user_lastname: u'Cotterell'
self: 
storage: 
user: 
url_string: 'https://auth.example.com:8181/ExternalAuthentication/
Login?username=matt...@example.com&password=x'

And seem to have been caused by psycopg2 here:

/usr/local/lib/python2.6/dist-packages/django/db/backends/
postgresql_psycopg2/base.py in execute

"""
def __init__(self, cursor):
self.cursor = cursor
def execute(self, query, args=None):
try:
   return self.cursor.execute(query, args) ...
except Database.IntegrityError, e:
raise utils.IntegrityError,
utils.IntegrityError(*tuple(e)), sys.exc_info()[2]
except Database.DatabaseError, e:
raise utils.DatabaseError, utils.DatabaseError(*tuple(e)),
sys.exc_info()[2]
def executemany(self, query, args):

query: 'INSERT INTO "auth_user" ("username", "first_name",
"last_name", "email", "password", "is_staff", "is_active",
"is_superuser", "last_login", "date_joined") VALUES (%s, %s, %s, %s,
%s, %s, %s, %s, %s, %s)'
self: 
args: (u'matt...@example.com',
 u'Matthew',
 u'Cotterell',
 u'matt...@example.com',
 u' ',
 False,
 True,
 False,
 u'2012-02-17 15:34:59.735209',
 u'2012-02-17 15:34:59.735222')
e: ProgrammingError("can't adapt type 'NavigableString'",)

So I know everything on my end is at least getting filled in properly.
Oddly enough, if I comment out the first_name and last_name lines, it
goes through (and causes a similar exception a few lines ahead on a
similar 'object creation' section of code. So maybe it's somethign to
do with those two lines?

It's just bizzare, I'm creating objects for other areas of the
projects perfectly fine, it's just here that it's being stubborn.
Googling the issue only highlights the fact it's likely a psycopg2
issue, but not much else.

Thanks so much to anyone who can help me here, I'm completely stumped
as to why such a simple operation can go so wrong...

Matt

Re: Problem loading integer data into database using fixture

[Gchorn]

Unfortunately, that doesn't seem to be the case.  I have the database
user and password in my settings.py file, but I still have to do a
"sudo su postgres" to switch to postgres in the terminal before I can
access my PostgreSQL database through the Django database API.
Otherwise when I try to access it through my normal username
"guillaume", I get:

Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/lib/python2.7/dist-packages/django/db/models/
query.py", line 69, in __repr__

postgresql_psycopg2/base.py", line 140, in _cursor
self.connection = Database.connect(**conn_params)
OperationalError: FATAL:  Peer authentication failed for user
"postgres"

However, I found a way around the "out" file issue I mentioned
earlier; I did a search for my yaml file and changed the write
permission on it to all users, so I was then able to access it while
in the API under the postgres username.  After I did so and attempted
to write serialized data to it, I got the following error:

>>> yaml_serializer.serialize(Player.objects.all(),stream=out)
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/lib/python2.7/dist-packages/django/core/serializers/
base.py", line 55, in serialize
return self.getvalue()
  File "/usr/local/lib/python2.7/dist-packages/django/core/serializers/
pyyaml.py", line 44, in getvalue
return self.stream.getvalue()
AttributeError: 'file' object has no attribute 'getvalue'

It does seem to have written to the yaml output file.  In that, I got:

- fields: {age: 25, ast: 1, blk: 2, drb: 17, fg: 7, fga: 16,
first_name: Jeff, ft: 7,
fta: 12, gp: 8, last_name: Adrien, mp: 63, orb: 5, pf: 13, pos:
SF, pts: 21, stl: 0,
team: 1, three_pointers: 0, threes_attempted: 0, tov: 2}
  model: players.player
  pk: 1

But now I'm wondering what the error the API kicked was about...anyone
know?

thanks,
Guillaume
