Re: How to convert 10 digit mysql date to django date format
Hi It looks like a unix timestamp. I cant remember what python uses to convert unix to a date objecr but should be pretty simple. Maybe strftime/strptime or you can just google it. ~Jakob On May 22, 8:13 am, laspal wrote: > Hi, > > How to convert mysql 10 digit date format to django date format? > example: > mysql date - 1219848914 > to django date - "22-05-09" > > thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Using Ajax with django from different domain and technology
Hi AJAX doesn't care what tech is serving the data as long as the format is what it expects (JSON). Doing cross domain AJAX calls it a bit more tricky, but you can do it with JSONP. It's not hard to setup when you have control of the json output. I know jQuery has it, but try to google it, there are plenty of good explainations of how to make it work. This is more of a javascript issue anaways so if you get stuck you could also try asking on an js list. ~Jakob On May 22, 6:56 am, Abhishoka wrote: > Hi: > > We are a non-profit charity organization having 25+ websites and want > to maintain a centralized database for the various events happening at > different places.

Storage API and Uploading to http based storage
I have run into an issue and was wondering how I might be able to solve it
in the best way:
For storage backends that are http based some (such as S3) require that you
submit a Content-Length header upfront.
This is not necessarily a problem for the save method which takes a file
like object since it can look at the object and determine the length before
sending it. Though it still isn't very good as the file like object might
contain a lot of data or be transmitting over the wire.
However, it becomes impossible with the current API to open a file object
for writing and use the write method to write over http as the content
length is required to be sent before writing any data.
storage = S3Storage()
f = storage.open("myfile.txt", "w") # need to send the length and possibly
other metadata here.
f.write(data)
This kind of implementation would be required for supporting uploading
directly via an UploadHandler or other data backend which requires the
length as the upload handler provides the data in chunks.
Any thoughts would be appreciated,
Ian

Announcing django-emailauth-0.1
Hi Group, I'd like to announce the first release of django-emailauth, a Django application which tries to provide all models/views/functionality for implementing hassle-free user registration and authentication based on users' emails instead of usernames. It's hosted on github: http://github.com/redvasily/django-emailauth/tree/master Direct download link: http://cloud.github.com/downloads/redvasily/django-emailauth/django-emailauth-0.1.tar.gz I borrowed some code/ideas from django-registration so if you see some similarities, well, that's not a coincidence. There are already some solutions to implementing email authentication with Django, like this: http://www.djangosnippets.org/snippets/74/ But this solution is very limited in the scope, breaks Django authentication test, so you can't just say python manage.py test on your project and get error-free output, it doesn't handle verification etc. django-emailauth on the contrary handles email verification, email changes and provides everything necessary for email-based authentication Another distinctive feature (which can be disabled) is that it allows users to have multiple email addresses. I occasionally plan to add support for EAUT/OpenID and in that case allowing one user to have multiple emails makes even more sense cause email is just one of possible identity mechanisms. There's not much docs, but it comes with a good example project which should work as a guide for integrating emailauth into your project. Emailauth is licensed under BSD License, so feel free to use.

Using Ajax with django from different domain and technology
Hi: We are a non-profit charity organization having 25+ websites and want to maintain a centralized database for the various events happening at different places. The database (MySql) has been implemented and we use the django framework admin module to communicate with the database. Our different sites use asp, php and plain html pages. In order to fetch data through the django framework and use it in all our sites we thought of using Ajax technology which runs on client side and should be independent of server technology. Different web sites are located in different domains. How to achieve this? Would Dujo, Jquery, Prototype, etc. help in this regard? Web sites running in different technologies in different domains need to communicate with the server running Django framework and get the data - any suggestions on how to go about implementing this?

If clients are actually see a 500 error response, at least means that
return part of socket connection hasn't been closed. Is that want you
really meant, or is the 500 error in the logs and clients get a blank
page.
If you could duplicate it, which it seems you can't, I would have
suggested using second recipe in:
http://code.google.com/p/modwsgi/wiki/DebuggingTechniques#Tracking_Request_and_Response
to try and capture request content and response to see how much of the
request is actually being received.
BTW, are you using mod_wsgi embedded mode or daemon mode?
Also post an actual example traceback and what errors you get in the
Apache error log just to validate the nature of the problem.

With the attitude you are displaying, ie., not wanting to watch a 20 minute video even though you have probably spent almost as much time as that here complaining about the length of the video, and also possibly not even wanting to spend the time to properly research yourself what documentation exists which may answer your questions, I'd suggest people aren't going to want to help you. If you want people to help you when you actually get to coding your Django application, you have to show that you are yourself making an effort to actually work things out for yourself first. There is lots of documentation out there which people have spent a lot of time on exactly so you can be self sufficient and not need to be spoon fed by others. As to your specific question about source code reloading, it actually depends on how you are hosting your Django application. If you are using Apache/mod_wsgi then read: http://code.google.com/p/modwsgi/wiki/ReloadingSourceCode As much as you seem to want to avoid the details about how your application may be hosted, reality is that how Python works and the quality of Python web hosting available out there, means you can't avoid knowing about it completely.

Re: IOError: request data read error (revisited)
I've had the same problem, and can't figure out how to resolve it. It
seems to have nothing to do with the amount of data being transfered:
it happens occasionally on the smallest of page requests/responses.
It also doesn't seem to be related to browser, unless several
different versions of IE *and* Safari have the same problem. I tried
disabling keepalives for Safari at least, and it doesn't seem to have
helped. I'd prefer not to disable keepalives in general, if I can
avoid it.
All of the error messages I've received have shown in the traceback
that they're coming through this function:
http://code.djangoproject.com/browser/django/trunk/django/core/handlers/wsgi.py#L131
It seems to me like there's an easy workaround (I'm sure the actual
fix has to be much lower level, in WSGI or Apache [or even lower])
that would at least stop my users from getting 500 errors: wrap the
contents of that function in a try block, and *don't* raise the
exception.
Otherwise, I'd have to wrap every view that uses POST in that, which
would be very annoying. Or maybe write middleware that just peeks at
POST before anything else gets it, so that I could catch it there.
Thoughts?
Thanks,
Jeff

Ignoring Definite/Indefinite Articles when Sorting
Hi All, I have searched around but not really found an answer to this. For a project I am working on the customer wants a list of publications to be sorted alphabetically, but ignoring the definite/indefinite articles "the/a/an". Eg, the list should sort like Adherence to ... The Effects of ... A Low Participation Rate ... Trends in ... Understanding ... What Stops ... Is there a way of doing this using the ORM or a custom manager without having to write custom SQL every time I need to get a list of publications?

Cannot reload a Django models module within a "manage.py shell" session
I know how to reload a regular Python module within a regular Python interpreter session. For some reason, I am having trouble doing that within Django's "manage.py shell" interpreter session. To recreate my issue, start the basic Django tutorial found here: http://docs.djangoproject.com/en/dev/intro/tutorial01/#intro-tutorial01 After creating the "polls" application and "Poll" class, start up the interpreter via "manage.py shell" and import the "polls" app into it. import polls.models as pm Create a new "Poll" object: p = pm.Poll() All is well and good so far. Now go back to your source and add any arbitrary method or attribute. For example, I've added: def x(self): return 2+2 Now go back to the interpreter and "reload" the module: reload(pm) Now try to use your new method or attribute: p1 = pm.Poll() p1.x() You'll get this message: 'Poll' object has no attribute 'x' What gives? I've also tried rerunning the import command, importing the module using different syntax, deleting all references to any "Poll" objects or to the "Poll" class. I've also tried this with both the IPython interpreter and with the plain Python (v2.6) interpreter. Nothing seems to work. Using the same techniques with an arbitrary Python module in a regular interpreter session works perfectly. I just can't seem to get it to work in Django's "shell" session. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Errr... Sorry, found out it was my fault. That should be:
(r'^', include('microcomaustralia.zoph.urls'))
I suspect I must have got this right on the other computers where it worked. As
a result django
was expecting another parameter for each url.

Is this a db caching issue or a sessions issue?
Hi guys, I'm trying to figure out if what is going on with the pages i'm building and how to fix it. I have an object of User which I put into the sessions: class User: def _get_points(self): return UserModel.point.current_value def _set_points(self, value): pass points = property(_get_points, _set_points) These are the models which I have defined: class UserModel(models.Model): uid= models.CharField(max_length=255, unique=True) class Points(models.Model) user = models.ForeignKey(UserModel) current_value = models.IntegerField() In my views, I do: user = User() user.points to get the current value of points for a certain user. However, after a certain page has been loaded and shown the current value, if I manually change the value in the db (MySQL) and reload the page, I still get the old value, before the db change. I've ruled out page caching as different parts of the page has changes. These other changes on the page was executed via the user object in the sessions (not manually through the db) and works fine. These are the middlewares that I have in: sessionsMiddleware commonMiddleware and SESSION_SAVE_EVERY_REQUEST = True --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

reverse URLs on Debian Lenny
Hello,
I have a Django application that works fine on Ubuntu Intrepid with Python 2.5
and Ubuntu Jaunty with Python 2.6.
When I try to get it to work with Debian Lenny however, I keep getting
NoReverseMatch errors.
louie:/home/django/photos# ./manage.py shell
Python 2.5.2 (r252:60911, Jan 4 2009, 17:40:26)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from django.core.urlresolvers import reverse
>>> reverse('person_list')
Traceback (most recent call last):
File "", line 1, in
File "/var/lib/python-support/python2.5/django/core/urlresolvers.py", line
254, in reverse
*args, **kwargs)))
File "/var/lib/python-support/python2.5/django/core/urlresolvers.py", line
243, in reverse
"arguments '%s' not found." % (lookup_view, args, kwargs))
NoReverseMatch: Reverse for 'person_list' with arguments '()' and keyword
arguments '{}' not found.
If in my urls.py, I change:
urlpatterns = patterns('',
[...]
(r'^(.*)', include('microcomaustralia.zoph.urls'))
[...]
)
to:
urlpatterns = patterns('',
[...]
url(r'^photos/person/$', 'django.views.generic.list_detail.object_list',
person_dict, name='person_list'),
[...]
)
ie. I copied from microcomaustralia.zoph.urls and pasted here, then it works:
louie:/home/django/photos# ./manage.py shell
Python 2.5.2 (r252:60911, Jan 4 2009, 17:40:26)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from django.core.urlresolvers import reverse
>>> reverse('person_list')
'/photos/person/'
So it would appear that on Debian Lenny, reverse URLs are broken when using
include(...)
Are there any known compatibility issues with Django and Debian Lenny?
If not, how do I debug this issue?
In all cases I am using the latest stable version of Django (1.0.2)
Thanks

"Brittle" is perhaps a little extreme, but yes, there are issues. All
I can say in our defence is that the Django test suite passes for us,
and passes on a wide range of projects on which we use Django.
However, there are use cases that we don't exercise - which leads to
reports like yours. If you open a ticket describing the problem you
are having (and, in this case, the workaround for people that
experience the same problem), we can look at addressing this in the
future.
Yours,
Russ Magee %-)

Strictly speaking you can't as the relationship between a VirtualHost
and a specific Python sub interpreter is dynamic.
You could work around it though by relying on the name of the sub
interpreter which is created. In mod_python you can access the name of
the sub interpreter using mod_python.apache.interpreter. In mod_wsgi
(requires mod_wsgi >= 2.4) you can access the name of the sub
interpreter as mod_wsgi.application_group. You obviously need to
import those respective modules first.
For the case of mod_wsgi above, the default generated application
group name, ie., sub interpreter, actually has the server name and
WSGI application mount point in it, so you wouldn't even need to
explicitly name the sub interpreter but just extract the server name
component out of mod_wsgi.application_group.
import mod_wsgi
server_name = mod_wsgi.application_group.split('|')[0]
Because mod_python defaults to one sub interpreter per virtual host,
vs, one per application like mod_wsgi, then the actual sub interpreter
name is probably the server name. So can just use it as is:
import mod_python.apache
server_name = mod_python.apache.interpreter
If you are in a situation where you are forced to run your application
in main interpreter then this will not work. For mod_wsgi you could
use daemon mode and name the process group the same as the server name
and instead access mod_wsgi.process_group. Otherwise the only other
way would be to use PythonImport or WSGIImportScript to import a file
which sets up a variable somewhere you can access, but then you need
to have such a file for each virtual host. Since for mod_wsgi at least
you are going to have one WSGI script file per host anyway, you
probably may as well set it at the start of it.

Custom ManyToMany intermediate table.
Hi,
I have the following models :
--->
class Warehouse(models.Model):
name = models.CharField(max_length=100)
shortname = models.CharField(max_length=3)
description = models.CharField(max_length=1000)
class Product(models.Model):
name = models.CharField(max_length=300)
category = models.ForeignKey(Category)
warehouses = models.ManyToManyField(Warehouse, through='Stock')
# ManyToMany intermediate table
class Stock(models.Model):
product_id = models.ForeignKey(Product)
warehouse_id = models.ForeignKey(Warehouse)
qty = models.IntegerField()
class Meta:
unique_together = ("product_id", "warehouse_id")
<---
What is the best way to write a python function to get the Total
Quantity of a given Product (s1.qty+s2.qty+...+sN.qty) ?
My solution was to select all Stock instance then check the keys
(matching product_id) and add all of them. Not so nice...
Any better solution ?

Re: Custom urlconfs in django.contrib.auth tests failing when reverse is used in templates
Figured this out somewhat: To get around this, you can do something
like this when referencing external apps in auth templates:
{% url project.other_app.views.other_view as view %}
This won't raise an error if that reference doesn't work.
Still, this feels a bit hackish. I think brittle auth tests are
something of a recurring theme here.

Add an 'action' field to each form, with a static value, eg add this
field to the loginForm class:
action = CharField(initial='login', widget=HiddenInput)
and then use logic like this:
if request.method == 'POST':
action = request.POST.get('action', None)
if action == 'login':
frm = loginForm(request.POST)
elif action == 'otheraction'
frm = otherForm(request.POST)
Even easier would be to submit them to different URIs.
Cheers

Rendering a form based on partly determined model state
Hello, I have just started using Django - looks very promising! I am trying to implement something resembling a web-based shop. A simplified overview of my situation is as follows: models.py --- class Country(models.Model) name = CharField(max_length = 100) currency = CharField(max_length = 3) class Product(models.Model) name = CharField(max_length = 100) price = FloatField() country = ForeignKey(Country , editable = False) class Transaction(models.Model) country = ForeignKey( Country , editable = False) product = ForeignKey( Product ) date= DateField() views.py --- class NewTransaction(ModelForm): class Meta: model = Transaction def newtransaction(request , country): return render_to_response(...) ... Now, an important aspect of this shop is that it operates in several different countries, and the available product are different in different countries. The database can typically contain four Product objects: ["Norwegian_Product1" , "Norwegian_Product2" , "Swedish_Product1" , "Swedish_Product2"] Based on the url the customer used I know which country she is in, and whether I should present the Norwegian products or the Swedish product. This id comes as the second argument to the view function, but when rendering the NewTransaction form I do not understand how to limit the rendereing ov available product to only those available in the customers country?! Any tips greatly appreciated. Regards Joakim Hove --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: FileBrowser: Models for media
as mentioned before, one benefit is to _order_ the materials for each
course.
second, I just prefer to use edit-inlines (foreign keys) instead of
m2m-fields (the interface with many-to-many is not really useful,
IMHO).

Re: django captcha

Re: model form validation always failing
I'm having the same problem - using a modelform
I've got two fields jad_file and jar_file, I notice when I look at the
html that they turn into
id_jad_file
and
id_jar_file
Is there a reason for this?

Re: UnicodeEncodeError
Thanks Karen.
This is a script that fetched some json from a remote service. I
switched from using the normal simplejson module to the one provided
by Django and that seems to decode things in a unicode safe way.

open flash chart 2 & django
Hi,
I'm trying to use Open Flash Chart 2 with django.
+ Installation
- I've downloaded OFC2 in this address :
http://sourceforge.net/project/showfiles.php?group_id=201148
- In my Django Project, I've created a directory (openFlashChart) for
the module with a __init__.py file inside.
--- I put inside these files : openFlashChart_elements.py,
openFlashChart_varieties.py, openFlashChart.py
- In my settings.py file, I've added in INSTALLED_APPS a line :
myproject.openFlashChart
+ View
In a view, I put this :
importmyproject.openFlashChart.openFlashChart as openFlashChart
frommyproject.openFlashChart.openFlashChart_varieties import
(Line,
Line_Dot,
Line_Hollow,
Bar,
Bar_Filled,
Bar_Glass,
Bar_3d,
Bar_Sketch,
HBar,
Bar_Stack,
Area_Line,
Area_Hollow,
Pie,
Scatter,
Scatter_Line)
frommyproject.openFlashChart.openFlashChart_varieties import
(dot_value,
hbar_value,
bar_value,
bar_3d_value,
bar_glass_value,
bar_sketch_value,
bar_stack_value,
pie_value,
scatter_value,
x_axis_labels,
x_axis_label)
def chart_data(request):
plot1 = Line(text = "line1", fontsize = 20, values = range(0,10))
plot2 = Line(text = "line2", fontsize = 06, values = range(10,0,
-1))
plot3 = Line(text = "line3", fontsize = 12, values = range(-5,5))
plot1.set_line_style(4, 3)
plot2.set_line_style(5, 5)
plot3.set_line_style(4, 8)
plot1.set_colour('#D4C345')
plot2.set_colour('#C95653')
plot3.set_colour('#8084FF')
chart = openFlashChart.template("Line chart")
chart.set_y_axis(min = -6, max = 10)
chart.add_element(plot1)
chart.add_element(plot2)
chart.add_element(plot3)
return chart.encode()
-
But I've got an error : Error was: No module named cjson

Get ServerName in settings.py
Hi, Given that my apache uses many VirtualHosts and within each a ServerName, how can I get that ServerName into a variable in my settings.py file? I am using WSGI and mod_python. (different setups on dev vs. server) The reason is that I need to be able to build the whole http://servername in functions all over the place, like the models and request context -- places where I *don't* have a request variable. All I have is access to settings.SOME_VAR -- hence I would like to get: apache: ServerName ---> settings.py: SERVER_NAME Any help/suggestions? \d --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Well, we've got the line causing the exception, and the exception, and
that's probably enough code in this case. We could use more information on
the environment.
The line in question is trying to print possibly Unicode data to a
device/file that is apparently set up to use the ascii codec. What is
stdout here? If it's a file, perhaps you can open it via the right codec.
Plain open() is going to use the ascii codec, which will be a problem for
any non-ascii data. Using codecs.open() you can specify whatever encoding
you like that will be capable of representing the data you have:
>>> u = u'\2013'
>>> stderr = open('/tmp/stderr.ascii.out', 'w')
>>> print >> stderr, '%s' % u
Traceback (most recent call last):
File "", line 1, in
UnicodeEncodeError: 'ascii' codec can't encode character u'\x81' in position
0: ordinal not in range(128)
>>> import codecs
>>> stderr = codecs.open('/tmp/stderr.utf8.out', mode='w', encoding='utf-8')
>>> print >> stderr, '%s' % u
>>> quit()
If stdout is a device, and you can't reconfigure it to support non-ASCII
output, then you'll have to take care not to send non-ASCII data to it. You
can print repr of the Unicode strings instead...that will be ugly but at
least it won't cause an exception.

Decimal format fields in Admin
I have a model/table with a field declaration: money=models.DecimalField(max_digits=12, decimal_places=2,verbose_name=u'π/υ'). When I see this field in the Admin pages, this field is just a box, without any formatting, e.g. thousand separation marks, which is important for the visibility of the amounts, such as 1700 instead of 17.000.000,00 (in my country we use '.' as thousand separators, and ',' for decimals).

ViewDoesNotExist error on Apache2 with mod_wsgi
Greetings.
I have to deploy a Django application in Ubuntu for my current
assignment. I've already finished my application on Windows, yet I'm
having trouble migrating it to Ubuntu. It runs just fine when I use
Django's server (python manage.py runserver). However, my assignment
specifically requires that the application runs on Apache2 (and other
web servers later on, but for now I just need to worry about Apache2).
httpd.conf:
LoadModule rewrite_module libexec/mod_rewrite.so
LoadModule wsgi_module modules/mod_wsgi.so
WSGIScriptAlias / /home/miguel/Blog/apache/django.wsgi
django.wsgi:

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
sys.path.append('/home/miguel/')
sys.path.append('/home/miguel/Blog/')

blog application is located in /home/miguel/Blog/blog/.

The Django tutorial mentions this -- a Django QuerySet is "lazy", which means that it doesn't do a query until it absolutely has to. So, for example, simply writing "SomeModel.objects.all()" doesn't immediately execute the query -- you can tack filters and whatnot onto it, and all they'll do is refine the query that eventually gets executed. In this specific case, slicing a QuerySet (e.g., "SomeModel.objects.all()[:5]" or whatever) will just add a LIMIT clause to the query that gets executed, rather than retrieving all the objects and then plucking a few out. -- "Bureaucrat Conrad, you are technically correct -- the best kind of correct." --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Split models.py to smaller parts.
First of all thanks for all responses.
I've still one more question which is connected to that one particular
issue. What if classes are importing each other.
models/
__init__.py
one.py
two.py
== __init__.py ===
from one import ModelOne
from two import ModelTwo
=== one.py
from django.db import models
from two import ModelTwo
class ModelOne(models.Model):
two = models.ForeignKey('ModelTwo')
class Meta:
app_label = 'appname'
def all_one(self):
return ModelTwo.objects.all()
=== two.py
from django.db import models
from one import ModelOne
class ModelTwo(models.Model):
one = models.ForeignKey('ModelOne')
class Meta:
app_label = 'appname'
def all_two(self):
return ModelOne.objects.all()
In case above appears problem with cyclic import. I know that example
is a bit silly but I'm trying to use it in real project files with
more than 1000 lines ~300 per class.

Re: FileBrowser: Models for media
I´d use a slightly different approach:
class Course(models.Model):
name = ...
class Material(models.Model):
course = models.ForeignKey(Course)
media = FileBrowseField(max_length=200, blank=True, null=True)
order = models.PositiveIntegerField("Order", blank=True,
null=True)
the positive side effect is, that you´re able to _order_ your material
(which might - sooner or later - be necessary).
about subclassing filefield or filepathfield: there´s no good reason
whatsoever. if you think it´s better to subclass any of the given
fields, you may want to submit a patch.
thanks,
patrick

Use low-level Django cache framework to cache retrieved object but don't forget to invalidate the cache upon each change to this object.

Multiple decorator and maybe caching, not sure
Hello, I've written a few decorators for my views. Each of the decorators operate on the same object obtained from the db backend using ORM and each checks different things. I'll chain them together sometimes, but not always. In the decorated view I'll usually be doing yet another MyObjectClass.objects.get(...) (as I've done in each of the decorators already) to carry out some operation or other on the object. My question is, is there some way to either avoid having to make repeated ORM queries in each of the decorators or to cache the result of the first ORM query (no matter which decorator it's obtained from)? All I'm usually doing it a .get(id=123) to get an object to work on and it feels wasteful. Is some form of middleware to cache db queries the "done thing" here? Not sure where to start.

UploadHandlers and the Storage API
Hi all, I am currently using an implementation of the django.files.storage API to read/write files from Amazon S3 using the django storage API. This has worked well except for in cases where one wants to read from one stream and write to the storage API. One case I am running into is that I would like to create an Upload handler that skips putting files in tmp/ and uploads them directly to S3 as the files could be quite large. I could do this by writing directly to S3 but I would rather go through the storage API as I would like to change it out for the local storage API when developing/running tests. The storage API currently handles writing itself in the save method by reading from a file like object, but you currently can't do the opposite where you are given chunks of data and you want to pass them along. Is there a particularly good way to solve this kind of problem? Ian --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
