Re: what to do instead of adding to Query.extra_where ?

[Paul Winkler]

Hah. That was a pretty long message relative to how quickly I found
the answer myself :-p
Sorry for the noise.

For posterity, extra(where=...) is indeed the solution. I overlooked
the obvious:
the class I was trying to fix is itself a subclass of QuerySet.  So
given this line:

clone.query.extra_where += ('db_newsitem.id =
db_attribute.news_item_id',)

the replacement is now:

clone = clone.extra(where=('db_newsitem.id =
db_attribute.news_item_id',))

Seems to work fine.

What URL are you using? Sounds like you are using:

  http://localhost

and not:

  http://localhost/myapp

Your WSGIScriptAlias has it mounted at sub URL not root of site which
is where standard Apache 'It Works' page would be found.

what to do instead of adding to Query.extra_where ?

[Paul Winkler]

Hi folks,

I'm working on a codebase (a fork of http://code.google.com/p/ebcode/)
that is supposed to be run against Django 1.1. It has several lines
like this:

clone.query.extra_where += ('db_newsitem.id =
db_attribute.news_item_id',)

That line raises a traceback like this:

Traceback (most recent call last):
  File "./everyblock/everyblock/cities/boston/building_permits/
retrieval.py", line 90, in 
PermitScraper().update()
  File "/home/pw/builds/openblock/builds/20100824/ebdata/ebdata/

super(NewsItemListDetailScraper, self).update()

clone.query.extra_where += ('db_newsitem.id =
db_attribute.news_item_id',)
AttributeError: 'GeoQuery' object has no attribute 'extra_where'


For more context, the relevant models.py code is at
http://github.com/openplans/openblock/blob/master/ebpub/ebpub/db/models.py
and `clone.query` is an instance of
django.contrib.gis.db.models.sql.query.GeoQuery, which inherits from
the usual BaseQuery.

Now, I've found by googling and downloading old releases that
django.db.models.sql.query.BaseQuery had an extra_where attribute as
of Django 1.0, but it's gone in Django 1.1.
And from looking at recent and old versions of the docs, I don't think
that extra_where was ever really part of the API; you're probably not
supposed to twiddle it directly.

I haven't yet found a documented way to solve this.
http://docs.djangoproject.com/en/dev/ref/models/querysets/ talks about
the .extra(where=...) method,
but that's part of the manager API and the QuerySet API, not the Query
API.

The one thing I've found, by poking around in the django source, is to
call clone.query.where.add(ExtraWhere(...)) but it's not clear to me
whether that's really part of the API either. Is there a better /
"correct" way?

Thanks,

Re: mod_wsgi, apache, windows XP

[Jesse]

I'm using Python 2.7, Apache 2.2 and grabbed the mod_wsgi that
supposedly works.  I changed the name of the file to mod_wsgi and
placed into Apache modules library.  I changed the folders, so the
apache folder by itself and created the following in the apache
http.conf file:
WSGIScriptAlias /myapp "c:/public/apache/myapp.wsgi"


Order allow,deny
Allow from all


The myapp.wsgi is:
def application(environ, start_response):
status = '200 OK'
output = 'Hello World!'

response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)

return [output]

Apache starts fine, no errors, but the localhost is still the original
apache page and not hello world.

I guess I do not understand your reply.

I'm already iterating through the fields in the template, accessing
them by name.  Actually, many forms' worth of fields, in a many-rowed
table.  How would I display the product description for each row as
flexibly-wrapped text, rather than as a field widget?  That is what I
am trying to do.

Sorry if I am missing something that should have been obvious to me
from "whatever HTML construct".  Could you provide an example (or even
another hint), that works with a formset?

The full traceback would help diagnose. Is there any possibility your
installation of Django is corrupt -- like from a partially-applied install
of 1.2.1 over 1.1? That's rather what it looks like.

Does the Apache error log have anything in it?

Which Apache version? Which Python version? Which mod_wsgi object did
you grab, or did you compile from source code?

Are you trying to run 64bit Windows?

BTW, recommended to test first with a WSGI hello world program and not
Django.

See hello world example in:

Re: multiple oracle database queries in one request problem

Hi,

I'm deploying a site on windows with oracle (and I don't know either of
them well). Simple apache+wsgi setup for now.


I'll have to test it out tomorrow when I'm near the windows machine 
again, but I might have found the solution in an existing bug report: 
http://code.djangoproject.com/ticket/13351


In a threaded situation (which you always have with mod_wsgi on 
windows), you apparently need to pass the cx_oracle database driver a 
threaded=True option (which is off by default).


So I added the following to my database config and I'm hoping I'll be 
happy tomorrow morning...


'OPTIONS': {'threaded': True}


I'll update the ticket when it helps.

Re: Surreptitious caching of JS in Django

[buddhasystem]

I really didn't configure any caching of JS myself, with the exception that
it gets served statically. Disabling cache altogether is not an attractive
option as my testing goes against expensive queries.

Re: fetching values from model

[Justin Myers]

The only way to access a model from within a template is if the view
specifically passed it via the template's context. Even then, you
wouldn't be able to do much passing the model _class_ this way; you
should be passing specific model _instances_. As the design
philosophies doc says, "We see a template system as a tool that
controls presentation and presentation-related logic – and that’s it."
http://docs.djangoproject.com/en/dev/misc/design-philosophies/#template-system

{% load %} is completely unrelated. It's used to load custom template
tags and filters: 
http://docs.djangoproject.com/en/1.2/howto/custom-template-tags/

Discrepancy between model formset and the queryset it's based on

[ses1984]

Basically I have a queryset with N items in it, which I use to create
a model formset, which then has N+1 items in it. I'm not sure why this
is happening.

Here is a summary of the problem. Please forgive my crude methods for
gathering information (if anyone has feedback on that topic, I would
like to hear it)

Re: PIL on 10.6 = PAIN

[keynesiandreamer]

Well last night I started working on removing all traces of PIL and
libjpeg as well as the install instructions from Andrews link (Thansk
Andrew!)

If there was a problem to encounter I seemed to hit it... :-(

It all started when Git would not unzip, I finally got that with the
xjvf flag I believe, and then now I get an error due to a dylib not
being linked to x86_64 architecture. JESUS!

I spent time trying to research that without much luck :(

I upgraded the default mac installation python to python 2.6.6 and
also am using virtualenv for my django envs and am having issues
installing virtualenvwrapper, yet another install problem... Looks
like something with the the source file and the virtualenv_bashrc
file.

Atleast in the morning my patience is a bit better... I will try
hammering away at it again tomororw. I think I need a day off from it.

Thanks everybody for all their insight and advice, it is very much
appreciated. If you are anywhere near SF, there is beer on me for it.

-Ben

It's two underscores each side, not one - __unicode__, not _unicode_.

_unicode_ method not working?

[Erskine]

Hi,

I've just started using Django and have been following the 'Writing
your first Django App' tutorial. So far so good, but I've run into a
little irritation - the use of the _unicode_ method doesn't work for
me. I'm using Django 1.2.1. I'm pretty sure I've got the indenting
right, but when I run the Python shell the only response I get for
Poll.objects.all() is Polls: poll objects and not the objects
themselves. This is my code as I've been following along on Page 1 of
the tutorial.

Thanks


from django.db import models
import datetime

class Poll(models.Model):
question = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def _unicode_(self):
return self.question
def was_published_today(self):
return self.pub_date.date() == datetime.date.today()

class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(max_length=200)
votes = models.IntegerField()

Pretty sure that should be "generic.list_detail", with a dot instead
of the first underscore. You'll have to look through your code to see
where you've used that, as it's not in the code you supply below.

Querying a many-to-many field based on entries' number in the relationship

[Jordon Wii]

Hi,
I have a model named 'Period' and a model named 'Schedule'.  They have
a many-to-many relationship.  I need to get all Period's whose
position in the relationship is a certain number (All second periods
in each schedule, for example).

I could use raw SQL to query the m2m database, but is this possible
without raw SQL?

Re: how to add a non-field text property to forms in a formset

[Bill Freeman]

This seems to me to be a job for the template.  The forms documentation has
a section on custom rendering which shows you how to iterate through the
fields, or access them by name.  You would insert whatever HTML construct
was appropriate for your text, providing a context variable giving its contents,
if necessary.

The url resolver takes care of all of this magic for you. If you find
it isn't, then you aren't using it right. For instance:

link

This is clearly an incorrect use of a url pattern. Instead, the var
argument should be included as part of the urlpattern, and var given
as an argument to the url template tag.

link

Do it like this, and you won't have problems. If you need to generate
a query string, use the pattern as described by Alexandre González in
the first reply.

Cheers

Tom

how to add a non-field text property to forms in a formset

[bobhaugen]

I often want to add properties to a formset that will fill a table
cell with flexibly wrapping, read-only descriptive text.  For example,
the description of a product, where the enterable field is the
quantity ordered.

If I use a field, the widget gets a fixed width and the contents do
not wrap (unless I use a Textarea, which then gets a fixed number of
rows).  The product descriptions can vary from one word to a military-
style extended riff on options.

Moreover, if I understand correctly, it is either not possible or
unwise to display the initial value of a field as a string.

So what I end up doing is rolling my own set of forms (that is, not
using a formset) where I can add extra text properties to each form at
will.

Any other better solutions to this problem?

Did I miss anything in the above description?

Thanks.

seeing HTML code, not the interpreted html

[Bradley Hintze]

Hi all,

I am playing with iframes for the first time and am gelling some
undesired results. The 'stuff' in my frame shows as HTML code instead
of the expected html 'interpretation.' I hope that made sense) I am
looking to fix this. Here is what I did: I generated a string with all
my html in it and saved it under a request.session key. On my template
I simply put {{ key }} and thus I get my result.

Can I ge django to interpret my strinng as HTML?

Heres the relevant code


results.html (template)
...

  Your browser does not support iframes.

...

urls.py
...
(r'^rotamer_diff/$', rotamer_dif_frame),
...

views.py
...
def rotamer_dif_frame(request):
return render_to_response('rotamer_dif_frame.html',
request.session, context_instance=RequestContext(request))
...

rotamer_dif_frame.htm

Multiple authentication sources to one database

[Alex]

I am trying to write an application that allows two different kinds of
authentication: Users in the wild can register and use the site with a
new username, password and email and authenticate as usual, and others
can use a single-sign-on solution provided by my university. django-
cas (http://code.google.com/p/django-cas/) and django-cas-provider
(http://nitron.org/projects/django-cas-provider/) both handle the
single-sign-on solution, but they overload the username field to
correspond to the username provided by CAS. This means that if someone
registers as "johndoe" then someone who authenticates as "johndoe"
with CAS will suddenly have access to the internals of the other
account.

Is there a way to separate out these authentication methods so that
both can be used on the same django installation? (They both need
access to the same database of information.) If this isn't possible, I
may try to create a whole second instance of django running on the
same database (but then they both will want to use the "auth_users"
table anyways).

How is this feature called?

[norus]

Hi all,

I've decided to start learning Django and Python at the same time. The
project I'm working on will help configure Nagios directly from the
Django administation page. Here's a sample screenshot of what I've
done so far: http://valiyev.net/tmp/progress.png

Now my question is as follows, under "Check options", how do I add an
additional CharField where I would be able to submit arguments to the
command in "Service Checks"? Here's how other people did it (all I
could find was this screenshot: 
http://www.linuxaddicted.de/blog/wp-content/uploads/2009/03/picture-6.png).

Thanks in advance.

Re: {% csrf_token %} template tag not outputting the hidden field

[Jonas Geiregat]

I had the same problem some day's ago.
Did you add the context_instance parameter in the render_to_reponse function 
call. It's needed for CSRF to work.

For example: return render_to_response('blog/index.html', {'posts': posts}, 
context_instance=RequestContext(req))

Jonas.

Re: Query overhead or not ?

[Jonas Geiregat]

Tag.objects.values('name').annotate(times_used=Count('post__tags'))

That's the solution!

Re: Chat application in Django

[David Koblas]

 Two challenges with long polling and Apache/mod_python -

* First is that you'll need to have N-user connections open at a minimum 
based on the number of users you have using the system simultaneously.  
Thus your memory footprint and performance is going to suffer as the 
number of users increases.


* Second - the demo app I have assumes a single process model for 
handling communications (e.g. all notification is done via callbacks).  
So you would need to build some kind of server who maintains state if 
you ran things under apache (multi-process dispatch model).

@ebry1,
Imagine 1 people live chatting, that means 1 requests per

delivered. (as example). Polling will bring your net throughput of the

Can you suggest me the side effects of using Sockets via 1x1px flash

I am working on a chat application in Django, how can I ensure that I

Possible approaches that I've been to:

1. BAD - use polling.

2. Use long polling - bad approach afa browser support is concerned.

3. Using sockets in flash - makes the application flash dependent.

Is there some good way to do this? Or if there is something Django
specific? Something like HTTPBinding or any 3rd party tested libraries?
I am expected to provide support till IE6. :-(

Correct me if I am wrong, flash is available on 95% of the systems, this
approach looks like safest bet, is it good to go?

Btw, how does Gmail and FB chat works?

The {% load %} tag is for loading custom tags. Nothing to do with
accessing the database.

Why do you find it desirable to load records in the template?  What's
wrong with doing it in the view, which is what everyone else does and
how Django is intended to be used? See Jonas' remarks below.

multiple oracle database queries in one request problem

[Reinout van Rees]

Hi,

I'm deploying a site on windows with oracle (and I don't know either of 
them well).  Simple apache+wsgi setup for now.


Problem: one specific page kills off the mod_wsgi/django part. The rest 
of apache keeps working. "Kill off" meaning "it doesn't react anymore 
and takes quite some time for apache to kill it when I close apache.


The only error message I can find is an
"errno 10054" "existing connection was forcibly closed".  I can only 
guess that the remote database server closed something.



The specific page is the only one that fires off queries to both 
databases, so within the same request.  Anyone got any hints on where to 
look?  How to debug?   How to fix it?



Reinout (who dislikes the amount of handy debug info he's got...)

That's probably something you configured yourself.

Hi,

thanks for the tips! to answer your questions:

1. our model doesnt specify a coordinate system, it just saves the lat

2. i thought transforming had to be done to make a lat/lng point
"spatial" before distance was calculated. have i got that wrong?
3. i'm not actually sure we even have a "geodatabase". all we have are
pointfields in the model for users, which save the lat/lng points from
google.


Those PointFields are what make it a geo database (well, that's how I 
use the terminology anyway).


So your_object.your_point_field.distance(another.your_point_field) ought 
to give you a distance alright.


I don't know from the top of my head which unit that distance is in. 
I've only had to pick the closest one till now :-)



i'm not really capable enough to know how to proceed on my own from
your points, but for now i'll try removing the transform() (and also
placing it after) and i'll also specify the transform SRID of 900973
(is that the SRID for google or are you talking about something else
with that number?)


Oopsie, that's 900913 instead of 900973 (google written in characters

Re: PIL on 10.6 = PAIN

[Mathieu Leduc-Hamel]

This is because you should not use the Python interpreter from you're
Mac installation. Are you using buildout ? VirtualEnv? or nothing ?

Buildout:

/opt/local/bin/python2.6 bootstrap.py

Virtualenv:

virtualenv -p /opt/local/bin/python2.6 

Nothing:

/opt/local/bin/python2.6 manage.py runserver

Django RawQuerySet with Oracle CLOB

[huw_at1]

Hi there,

I've recently been using the raw() manager method to perform a few
more complex SQL queries on my Oracle DB and this has been working
very nicely. One particular SQL, however, appears to be giving blank
or phantom objects:

raw_query_list = list(tmp_class.object.raw(SELECT TO_CHAR(clob_column)
AS tmp_char, pk AS tmp_pk FROM table_name WHERE conditions))

where the tmp_class consists of:

class tmp_class(models.Model):

tmp_pk = models.IntegerField(primary_key=True)
tmp_char = models.TextField()

class Meta:
managed=False

Running the SQL query through cx_Oracle gives expected results however
when trying to present the list through a template the objects all
appear as blank. I realise that strictly speaking converting CLOB to
VARCHAR2 gives rise to potential issues over string length however in
this case all values in the CLOB column are less than 4000 characters.
My problem is that I am unsure as to where to start debugging. If I
had to guess at what the source of the problem was given the symptoms
I would say that it was something to do with the fact that CLOBs
operate using memory pointers rather than actual values so the phantom
objects are displayed as a result of the pointer being at the end of
the column. I could have made a mistake with the model however so I am
unsure. Any suggestions?

Many thanks as ever.
