How do I manage the order of related objects?

[scelerat]

I've got a part/collection pairing of objects tables, and I'd like to
know the best way to manage the order of things inside the table.

Briefly:

class Activity(models.Model):
# etc...

class ActivityPart(models.Model):
order   = models.IntegerField("order in parent", default=1)
activity   = models.ForeignKey( Activity )
# etc.

What I want to do is, upon creation of an ActivityPart, figure out the
other parts already pointing to an Activity, and increase the order
number before saving the part if there are already ones with that
number. I also want the parent object to know about all its Parts. I'm
not sure what the best way to do either of these is... it seems like I
could do some or all of this in the ArrayPart's __init__ method, but
maybe there's a more Django-ish way?

Duplicating sitemap dictionary with a get variable

[Alessandro Ronchi]

I have a sitemap dictionary.
I want to add in my sitemap.xml an url for every url of my sitemap with a
?lang=en ending. Is it possible?

So, if my sitemap contains:
http://www.detectorpoint.com/
http://www.detectorpoint.com/about/

I want my sitemap to contain:
http://www.detectorpoint.com/
http://www.detectorpoint.com/?lang=en
http://www.detectorpoint.com/about/
http://www.detectorpoint.com/about/?lang=en

I have hundreds of pages, so I cannot do that by hand...

When you test importing caliber.settings at the command line, with your
Python path set to exactly the above, what happened?

Depends very much on which users you're talking about, and since the set
of "natural expectations" of all users contains contradictory elements
(different users expect opposite things), it's not really a good
measure.

In any case, Django's order_by() is a proxy for database sorting, which
is typically lexicographic using ASCII (or unicode, depending on the
setup of the database).

> For example, sorting by name for a set of objects with names: img10,
> img1, img103, img2, img3a, img3b

You've left out a few words from your sentences, so it's unclear if this
is what you're seeing or what you're hoping to see.  If I insert those
values into a table and order by that field, I get back the results in
this order:

 img1
 img10
 img103
 img2
 img3a
 img3b

That isn't going to be amazingly unclear to anybody who's ever used a
computer, since that's the way filenames are sorted pretty much
everywhere. Sure, it might be nice to say you want it to read img1,
img2, img3, etc, but the current output isn't vastly inferior. Also,
this "alphanumeric" sorting that you're after (and it's not really a
good name which is why I've quote it; the current sorting is a logical
sort on alphanumeric values as well) requires some "smarts" from the
sorter to know which digits are actually numbers and which are simple
characters as part of the name and you still end up having to sort
digits relative to letters (for example, think about sorting "a23b" and
"abc". Or, where do "img03" or "imgxyz" sort in the above list? How
about "img1.2"?).

To do things differently at the database level would require passing the
output column names through functions (at the database level). Right
now, there's no way to do that via Django's ORM (and no really concrete
plans to add anything like that, either). Even doing it at the raw SQL
level, unless your database contains some special function to handle
this, would be quite fiddly. The type of sorting function you're after
is very uncommon, since it requires a lot of extra processing for each
element.

Sorry that that sounds like a bunch of bad news, but that's the way
things are. Humans are very adjustable. The lexicographic sorting that
happens now tends to be fairly readable and not particularly confusing.
The alternative is computationally intensive.

Malcolm

Model manager natural sort order

[Delta20]

Is there a way to make a model manager get_query_set function return
items sorted in natural alphanumeric order? order_by returns things in
rather than the ASCII order, which is not generally what users expect.

For example, sorting by name for a set of objects with names: img10,
img1, img103, img2, img3a, img3b

For a start, this line is just plain wrong. The django.root option has
nothing to do with file paths. Remove the line. You don't need it for a
Location of "/".

> PythonPath "['C:/projects/''] + sys.path"

At a minimum, there's a typo here. Count the number of single quotes
you've got there. It should be an even number (one to start the string
inside the list and one -- not two -- to finish it). Once you fix that,
I suspect things will work.

Mod-Python = Headaches (cannot find my settings file)

[mclovin]

I have my project settings file in:

'C:/projects/caliber/settings.py"

I have mod_python activated (latest version as of today) along with
Apache (latest version as of today)

Now this is at the bottom of my httpd.conf file:


SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE caliber.settings
PythonDebug On
PythonOption django.root 'C:/projects/caliber/'
PythonPath "['C:/projects/''] + sys.path"


I have also tried:

SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE caliber.settings
PythonDebug On
PythonOption django.root 'C:/projects/caliber/'
PythonPath "['C:/projects/caliber''] + sys.path"




Both of them give me teh same error:
---
ImportError: Could not import settings 'caliber.settings' (Is it on
sys.path? Does it have syntax errors?): No module named
caliber.settings
---



I only have installed and used apache and modpython under ubuntu
before and everything went great. This is the first time I am
installing it in Vista (i cant change OS's) and it is giving me this
error!

Hi,

You need this template context processor [1], witch is there by default. And
you need to use RequestContext in your views too [2].

The SQL you've posted certainly looks wrong and I thought I'd spent
enough hours making sure we never constructed something like that. So
there's some edge-case you're hitting that isn't being catered for. No
big deal; we can fix that. However, the model fragments you've posted
don't support the SQL that's being generated. Thus, some of the stuff
you've trimmed is likely to be relevant. Filtering a
"software_installation" model on the "software" field isn't going to
involve selections on the license_key table at all. 

Please open a ticket for this and assign it to me (mtredinnick in Trac),
since these tend to be the bugs that I get to fix. However, first,
pleaes create a small, complete example that demonstrates the problem in
a repeatable fashion. Simplest way to do that is to take your existing
models and start removing as many fields as possible until the problem
goes away. You can view the SQL that Django will generate by looking at 

qs.query.as_sql()

where "qs" is any queryset (such as
software_installation.objects.filter(...)). You can't do this with
something that returns an immediate result (such as .count()), but
that's because count() doesn't return a queryset; it returns an integer.

The fragment you've posted above doesn't meet the "complete" definition,
since (a) it doesn't have anything for the "software" model, although
that's referred to and (b) if I was to create an empty software model
and run the query, license_key wouldn't show up in the query.

Malcolm

The "since" bit doesn't follow. The post_syncdb signal is only emitted
once by the syncdb management command.

There's a slight oddity in the way the post_syncdb signal is emitted
(it's not a completely silly idea, but it takes some getting used to and
we could have maybe done it differently). It sends all the models that
were created, not matter what application they're in, but it emits the
signal once for each application (setting the "app" and "sender"
parameters to the different application name each time).

However, this does mean you have to check, for each model in the
"created_models" parameter, whether it's a model in the application you
care about or not.

> Or do you need to write the callback method the way, that it can be called

You need to do this if your action doesn't depend on particular models.
The post_syncdb signal is sent for every application in your
INSTALLED_APPS list, regardless of whether or not they were changed.
However, you can tell if some model in the application was affected by
looking to see if it is in the created_models parameter list.

So, if you're writing a post_syncdb handler that doesn't act on
particular models, but does something for the entire application, you
need to check whether you've done it before.

Malcolm

You could use a user profile model to help with this (see [1]). In your
user profile, have a flag that indicates whether the user is registered
or not. Then periodically go around and clean up (delete) any users that
do have registered=True in the user profile.

You cannot automatically do this "when the session is completed", since
you won't know when that is. Most users don't bother to log out of
websites or anything like that. How can you tell the difference between
"user has gone to lunch and will be back in 20 minutes" and "user has
finished using the site and will never be back"? You can't. You just
have to do something like deleting temporary users after 24 hours.

Which cache backend are you using? UnicodeDecodeError occurs when
converting from bytestrings to unicode and, as far as I can see, none of
the set() methods for caches should be doing this.

[...]

It's difficult to be certain about this without knowing where the
contents of "cached" came from originally, but I'll guess it's loaded
from the database.

Right now, Django doesn't have any concept of "binary data" for database
storage. So it treats everything as strings and converts them to unicode
objects upon loading. That the conversion happens is well understood
these days (I hope). Your call to smart_str() essentially says "convert
this from a unicode object back to a str object" and by using
iso-8859-1, you're indicating that the full range of bytes might well
occur (ascii data is only going to occupy the lower 7 bits, whereas the
binary pickle protocol uses all 8 bits in the byte.

In a fashion, you can think of iso-8859-1 as the identity transformation
for bytestrings. In Python, it actually just maps every byte to itself
(even those that aren't valid iso-8859-1 characters). That's for
historical reasons, but it's also guaranteed behaviour and is quite
useful as a way to change the type from unicode to a bytestring.

That explains why iso-8859-1 can be used to change types (unicode ->
bytestring and back), but it doesn't explain why the original error is
occurring in the first place. I may have missed something when browsing
the code there, though.

If I'm understanding this correctly, you might want to look at  
template tags:
http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#howto-custom-template-tags

This would allow you to make calls to the database to retrieve  
whatever poll and related answers you want, render them as a stand- 
alone chunk of html, and then insert that html into an existing  
template. You could put it into the template as:


  {% get_poll_question some_poll %}


Where 'some_poll' was a variable that originates in your view.

Hope that helps,
Eric

no objects found

[Brian]

Django 1.0.2-1

If I do:

>>> object=models.software.objects.get(id=267)
>>> print models.software_installation.objects.filter(software=object)
[]
>>> print models.software_installation.objects.filter(software=object).count()
10

Huh? First statement says there are no results, next one says there
are 10.



If I spy on the packets, I see this in the SQL for the first
statement:

... LEFT OUTER JOIN `inventory_license_key` ON
(`inventory_software_installation`.`license_key_id` =
`inventory_license_key`.`id`)  INNER JOIN `inventory_license` ON
(`inventory_license_key`.`license_id` = `inventory_license`.`id`) ...

If I remove the inner join part (and the reference to it in the order
part), and run the SQL on the server, then it works.

`inventory_software_installation`.`license_key_id` == NULL on the rows
in question (the model specifies null=True).

I have a suspicion that the above SQL doesn't work because it requires
a inventory_license object, however there is no inventory_license_key
object there is no inventory_license object.

The relevant definitions (I can provide more details on request) are:

class software_installation(models.Model):
[...]
software = models.ForeignKey(software)
[...]
license_key = models.ForeignKey(license_key,null=True,blank=True)
[...]

class license_key(models.Model):
[...]
license  = models.ForeignKey(license)
[...]

class license(models.Model):
[...]


Any ideas?

Is this a django bug? If so is it a known issue?


Thanks

request.user objects in base.html

[izzy_dizzy]

Hi,

I'm new to django and I would like to know how to make request.user
objects available in context of base.html template. I wonder if
someone can give me a full code for a custom template tag for it.


Thanks in advance

Re: pizzas toppings, and subs

[mamco]

disregard, turns out it is quite simple.

create another mantytomanyfield on the sub model.

class Sub(models.Model):
# ...
toppings = models.ManyToManyField(Topping)

I had this earlier, but got an error.  I mis-read it to mean I
couldn't do just this, but turns out I had another issue altogether.

Problems with (Model)ChoiceField and the like

[James Smagala]

Hey All,

There is a discussion here about building dynamic form select fields
using __init__ on the form.  This, by itself, is not hard.

http://groups.google.com/group/django-users/browse_thread/thread/98bde0a6d818e627

Problem:  I have a formset that needs each form in it to be created in
this dynamic sort of manner.

Possible solutions:

- Create the formset containing no forms, add them individually, and
update the management form.  I had this mostly implemented, but I
don't know how to actually update the values on the management form.
Where do they live?

- Figure out some tricky syntax that lets me pass both the queryset
for a modelchoicefield (and an initial choice for said field) to a
form.  Also figure out how to pass it though a formset to correctly
init all those dynamic forms.  Not having much luck here.

- Post about it, and get told I'm doing it all wrong.  Suggestions are
welcome!

Please help!

James

pizzas toppings, and subs

[mamco]

in the documentation the many to many relationship between toppings
and pizzas is well presented (http://docs.djangoproject.com/en/dev/
topics/db/models/#many-to-many-relationships).  My question has to do
with something else that would have toppings, subs for example.

If in my toppings model, I've got my vendor, expected cost, minimum
order qty, etc, my pizza I have a description, box size,  and a price
to customer.  How would I integrate a 'subs' model which uses the same
toppings model, but also has some special details only about subs.

In my actual dilemma I'm converting an app to Django, and we have an
'address' table which stores the addresses for employees, vendors,
customers, along with an effective date for the address (which allows
us to hold the history of the addresses).  In the previous app, I
decided to go this route to have one bit of code that handled address
validation.

can I have a pizzas-pizzas-toppings and a subs-subs-toppings, as well
as perhaps some other things that use the ingrediants eg: donairs-
donairs-toppings?  Is there something in the documentation or django
book that covers this?  I haven't found it as of yet but still
digging.

Re: Slow application performance...

[Graham Dumpleton]

As before, if you can move to mod_wsgi and use its daemon mode try
that as first step. This will eliminate memory swapping issues and
other issues around startup cost of Apache child processes loading
Django. Also gives a more predictable environment in which can then
start doing testing as to how long requests are actually taking inside
your application/database.

Re: mod_python 3.3.1, Python 2.4.6, Apache 2.2.9 (MacPorts) on Mac OS X 10.5.6 (Leopard)

[Graham Dumpleton]

Use mod_wsgi instead, it should set up compiler flags correctly even
for fussy MacPorts. I can't remember if I rolled those changes into
mod_python in subversion trunk. If still want to try mod_python though
use:

  svn co https://svn.apache.org/repos/asf/quetzalcoatl/mod_python/trunk
mod_python-trunk

and use that version.

For other MacOSX/MacPort issues, see mod_wsgi documentation at:

  http://code.google.com/p/modwsgi/wiki/InstallationOnMacOSX

Some of these also affect mod_python.

With mod_wsgi, even if picks up correct framework, but wrong lib
files, you can override it to some degree using WSGIPythonHome
directive.

Anyway, use mod_wsgi if you can as am at point where can't be bothered
helping with mod_python problems anymore. ;-)

Re: Adding a view inside a view?

[Briel]

I'm not sure exactly what you want. Do you want a single poll, that
the admins can choose? Should users be able to create polls ect.
Anyways, in case you only want to display a single poll, the easiest
way to accomplish that would probably to create a boolean field called
display or front_page. Then you can import your poll model and filter
on it and get the one(s) that have True value for front_page. If you
want to make sure that only one can be displayed on the front page at
a time, you can create a method instead, that also will hold True/
False, but only allow one to be True at a time. You could also go with
the boolean field and just add the code in a view to make sure only
one is True at a time.

Hope this helps.

Re: Help with m2m relationships through intermediary tables

[felix]

open a shell with ./manage.py shell

from models import *

fetch one of your Authors (one that has a job already)

dir(author)

that will list all the ways you can poke at it.
always useful


you should see some way to access the AuthorNewspaper directly from the
Author object

to display a whole page of these positions you can fetch them directlly

AuthorNewspaper.objects.all()

an.author an.newspaper an.date

how/where to constrain the relationships in a model?

[Margie]

Supose I want to model the following: A Task is owned by a family but
may additionally have specific owners that are within that family.
The model would look like this:

class Family(models.Model):
   surName=models.CharField()

class Task(models.Model):
   ownerFamily=models.ForeignKey(Family)
   owners = models.ManyToManyField(Person, blank=True, null=True)

class Person(models.Model):
   family = models.ForeignKey(Family)

I want to enforce that the if a Task has owners, that each owner be in
the Family specified by that task's ownerFamily.

Could someone tell me where is the appropriate location in the code to
enforce this?  I'm not sure if there is a way to enforce this within
the model itself.  If not, then is the appropriate thing to do to just
check it in my public interface when I, for example, add an owner to a
task?

Thanks!

Fwd: [wingide-users] Integrating with django's unit tests

[James Matthews]

-- Forwarded message --
From: Philip Gatt 
Date: Wed, Jan 14, 2009 at 7:10 AM
Subject: [wingide-users] Integrating with django's unit tests
To: wingide-us...@wingware.com


Does anyone know how to integrate Wing with Django's unit tests? With my
django projects, I usually run my unit tests with the following command:

./manage.py test

I tried running unit tests within WingIDE, but the problem is that django
does some setup & cleanup work that needs to run before the tests can be
run. I'm not an expert here, but I suspect that we need to tie WingIDE into
django's test runner.

Thanks in advance,
Philip Gatt

Django VBulletin auth backend

[Chris H.]

Has anybody done any work on writing a Django auth backend for an
existing VBulletin[1] website?  I have a need to utilize the existing
user database in a Django project and would appreciate not having to
reinvent the wheel.  My google-fu has failed me on this one, so it may
not exist.

Any other examples of writing an auth backend for existing PHP apps
would also be appreciated.  Particularly implementations of single
sign-on using the PHP/VBulletin generated cookie.

Adding a view inside a view?

[Bradley]

I'm new to Django and I'm trying to modify an existing django website
for a local newspaper.  They would like to have a polls on the their
website.  I just used the tutorial from the djangoproject website to
create the polls module.  It works fine, except that I need it to work
inside a  section on the front page, not multiple pages like is
used in the tutorial.  What is the standard procedure for something
like this?

The tutorial had me create entries for /polls/ in urls.py  I probably
don't need those.
Do I somehow Integrate the polls function into already existing
function that are used to display the front page?  Not really sure how
to proceed

Any help would be appreciated.

Thanks,
Brad

Re: Slow application performance...

[SnappyDjangoUser]

I am having a similar problem with super slow performance in my
production environment (Apache with mod_python).  Does anyone have
suggestions of settings that I can try tweaking?

Graham has provided a lot of useful information earlier in the post,
but I am with Vernon in that I am unsure exactly how to start
debugging the root cause of the slow performance.

Thanks,

You dint bother to explain how you tried and beyond that you are

Re: Django Continuous Integration

[Adam V.]

We're using Subversion. We have one big repository, but we treat it
like two top-level repository, one for the website files themselves,
and one for build scripts and other tools. We're a small shop (<6
devs), so SVN is fine for what we're doing.

We're doing in-house development, so we don't package our project/app.

> Buildbot:  Do you use Buildbot or something similar for your Django
> development?  How does that work for you?  What other options are

We use CruiseControl.NET as our CI tool, since we're using that for
our .NET development anyway.
It watches SVN for changes and calls custom scripts written in Python
that look a little like this:
http://code.google.com/p/adamv/source/browse/python/buildsystem/

> Versioning: How do you mark versions of your Django project?
We're running against Django-trunk so far.

> Migrations: What do you use to track database migrations?
We're using MS SQL Server (since that's what our other stuff is in),
and we're using a 3rd party commercial tool called "RedGate SQL
Compare" to do schema upgrades. We keep our DB schema in source
control as a set of SQL files that gets run to create a new, empty
database.

Since we're doing Django on top of a "legacy" database, our Django
models don't own the bulk of the database, and SQL Compare is what our
main .NET apps are using to update schemas when we deploy that stuff.

{{ Point.y }}
{{ Point.x }}

should do the trick.

Re: mod_python 3.3.1, Python 2.4.6, Apache 2.2.9 (MacPorts) on Mac OS X 10.5.6 (Leopard)

[peterandall]

I've also tried doing this:

$  cd /System/Library/Frameworks
$  sudo mv Python.framework XXX_Python.framework

$  cd  
$  ./configure --with-apxs=/opt/local/apache2/bin/apxs --with-python=/
opt/local/bin/python2.4 --with-max-locks=32

Then editing the src/Makefile and updating the LDFLAGS to this:

LDFLAGS= -Wl,-F/opt/local/Library/Frameworks -Wl,-framework,Python  -u
_PyMac_Error $(PYTHONFRAMEWORKDIR)/Versions/$(VERSION)/$
(PYTHONFRAMEWORK)   -L/opt/local/lib

Then continuing to make and install mod_python

$  make
$  sudo make install
$  cd /System/Library/Frameworks
$  sudo mv XXX_Python.framework Python.framework


Still no luck, when i run: 'otool -L /opt/local/apache2/modules/
mod_python.so' i get the following:

  /opt/local/apache2/modules/mod_python.so:
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current

/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current

So its still building against the 2.5 version, this is really starting
to confuse me now, i've run out of things to try.

Thanks in advance for any help...

User Messages

[Tim]

Hi all -

I am using the messages framework to notify users when another user
has commented on their profile or on an item they've posted. I was
pretty excited to see that such an infrastructure was included with
the authentication system out of the box. However, I was disappointed
to see that the only way to retrieve messages was via a get _and_
delete operation, so each get (or reference to "messages" in a
template) emptied the queue.

I'd like to add some persistence to the messaging so that the queue is
flushed only when I specifically request it. But I'm not sure how best
to do it. My inclination would be to add something to my Profile model
and populate it with calls to get_and_delete_messages() at appropriate
times and never use "messages" in my templates at all, but rather just
pass the persistent object to the template.

Is there a better way to support Message persistence? Or should I just
build my own model to support this kind of thing? Rolling my own seems
fairly trivial since I'm already grabbing all the required information
anyway. But if it's not necessary, I'm not gonna do it.

- Tim

mod_python 3.3.1, Python 2.4.6, Apache 2.2.9 (MacPorts) on Mac OS X 10.5.6 (Leopard)

[peterandall]

Hi All,

I've been playing around with this for days and getting nowhere.

I've got python2.4 installed via macports along with the standard
Python2.3 and 2.5 installed in '/Library/Python/2.x'. I want to get
mod_python working for the macports version of python(2.4)

I've downloaded mod_python 3.1.1 and run the following commands (from
another post on django-users) to build it and install it:

$  cd /System/Library/Frameworks
$  sudo mv Python.framework XXX_Python.framework

$  cd  
$  ./configure --with-apxs=/opt/local/apache2/bin/apxs --with-python=/
opt/local/bin/python2.4 --with-max-locks=32
$  make
$  sudo make install

$  cd /System/Library/Frameworks
$  sudo mv XXX_Python.framework Python.framework

I've followed these steps to stop mod_python building against the
wrong version of python, yet in my apache error logs i get the
following errors:

[Wed Jan 14 16:14:50 2009] [notice] SIGHUP received.  Attempting to

So mod_python is still referencing the wrong version of python(2.5),
despite following the instructions to try and stop that happening.

Also to double check that, i restarted apache whilst i had the python
framework renamed (to XXX_Python.framework) and recieved the following
error:

Pete:~ Pete$ sudo apachectl restart
httpd: Syntax error on line 116 of /opt/local/apache2/conf/httpd.conf:
Cannot load /opt/local/apache2/modules/mod_python.so into server:
dlopen(/opt/local/apache2/modules/mod_python.so, 10): Library not
loaded: /System/Library/Frameworks/Python.framework/Versions/2.5/Python
\n  Referenced from: /opt/local/apache2/modules/mod_python.so\n
Reason: image not found

So by the looks of that it's saying the the mod_python.so is trying to
reference Python2.5 so hasn't built properly (i.e to ref python2.4)

**

So does anyone have any ideas as to why mod_python won't build to the
2.4 version installed via macports, despite me configuring it to use
that one.

Sorry if the post is a bit of a mess i'm not that great at all this
stuff. Any help would be greatly received,

Pete.

redirect to results

[Vince]

Hi everyone,

I am a bit confused about how to do what follows, I would appreciate
any help.

My django project is very simple I have a upload zip page, this page
processes a zip file and it is being decompressed and stored in a
folder for further purposes.
After I check and unzip the file I call the return_to_render

return render_to_response('upload_OK.html', {'nombre': filename,
'size': filesize, 'type': filetype, 'msg': msg, 'is_ok': isOk,
'zip_list': zf.namelist(), 'item': file_inzip})

I have a link in the upload_ok.html that is supossed to show the files
inside the zip file (see below)

[...]

   

Analyst DEMO server


Subiendo...
 
 
  {% if is_ok %}
 {{ msg }} 
 {{ size|filesizeformat }}
 Tipo de archivo: {{ type}}

http://aux/
unzip_results/">Visualizar ficheros descomprimidos
[...]

The problem is that i have already the template that shows the results
and it works if I change the return render_to_response line by another
call to a different template. as the variables that I need are all in
the same function (check, unzip and store in a folder).

If I change the return render_to_response line by:

return render_to_response('unzip_OK.html', {'nombre':
filename,'zip_list': zf.namelist(), 'item': file_inzip, 'iNum':
iCount})

it works as it shows the results. The thing is that I would like to
only show the results if the user wants to, once he sees that the zip
has been correctly processed (by clicking at the link)

How am I supossed to implement this, Can i pass parameters to another
function that calls the second return render_to_response ?

Thanks in advance

Vince

Re: Transactions not working

[Thomas Guettler]

You need to test if the data is already in the db first.
There is a handy method:

model_object, created = YourModel.objects.get_or_create(...)

If you still get this errors, you might want to check if
your sequence is in sync:

select max(id) from yourapp_yourmodel;

select * from yourapp_yourmodel_id_seq ;

Re: Getting a 'too many values to unpack' error

[Thomas Guettler]

yourmodel.objects.filter(a) does not work since a seems to be a queryset.

You need to use .filter(attribute=value) or something like this.

BTW: Why do you do all the select_related() calls?

ifequals Decimalfield comparison

[Ardesco]

So, I have a decimalfield that can be 3 different values. In my view,
I pass in a dictionary of values that contains the appropriate decimal
values as keys.

{% for item in booklist %}
{% for key, value in numvec.items %}
{{item.number}}
{% ifequals item.number value %}
{{value}}
{% endifequals %}
{% endfor %}

this is the dict I pass in as numvec:
numvec = {"TEST":Decimal("0.999"), "TEST2":Decimal("0.500"),
"TEST3":Decimal("0.255")}

the number field was defined as having these choices in my model:
BOOK_CHOICES = (
(Decimal("0.999"), 'TEST'),
(Decimal("0.500"), 'TEST2'),
(Decimal("0.255"), 'TEST3'),
)

The item number prints out just fine in the view if I compare the dict
with the attribute, but for some reason the ifequals cannot properly
compare two decimals together. Is this a bug, or am I doing something
wrong in my template with ifequals?

Re: Overriding Model's save method: error propagation

[Markus T.]

David,

for me, these two links did the trick:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#adding-custom-validation-to-the-admin
http://docs.djangoproject.com/en/dev/ref/forms/validation/#ref-forms-validation

However, validation as described in the Django docs does not happen in
the model's save method; it happens in the admin form. Above links
explain how to tell the admin layer to use your form class which
provides its own validation method. So you could alter the second
database in the validation method and raise a ValidationError if it
fails.
For example:

models.py:
class MyModel(models.Model):
  [...]

class MyModelAdminForm(forms.ModelForm):
  class Meta:
model = MyModel

  def clean(self):
data = self.cleaned_data

try:
  # alter other DB here

if x > y:
  raise forms.ValidationError(_("X must not be greater than y!"))

return data

admin.py:
class MyModelAdmin(admin.ModelAdmin):
  form = MyModelAdminForm

Getting a 'too many values to unpack' error

[Michael]

Hello,
Here is my code:

filter = {}
if request.GET.get('color', '').isdigit():
filter['color_cat'] = request.GET['color']
if request.GET.get('origin', '').isdigit():
filter['collection__origin'] = request.GET['origin']
styles = Style.objects.select_related().filter(**filter).distinct()
if request.GET.get('minprice', '').isdigit() :
if request.GET.get('size', '').isdigit():
a = Style.objects.filter(Q
(sandp__size__size_cat=request.GET['size']) & Q
(sandp__price__name__gte=request.GET['minprice']))
styles = styles.select_related().filter(a) ### This is the
line that is giving me the error!!

Whenever I do a search where the user enters a minimum price and
selects a sizeI get the error:

'ValueError at /search/ too many values to unpack'

The error comes from the line 'styles = styles.select_related().filter
(a)'

Re: Overriding Model's save method: error propagation

David,

I've been looking for a solution for this problem, too.
Maybe this helps - I'm yet to try this out:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#adding-custom-validation-to-the-admin

Things seem to be underway though:
http://code.djangoproject.com/ticket/6845

You must create your admin config eg:

class Media:
js = ('/static_media/js/tiny_mce/tiny_mce.js', '/static_media/
js/textareas.js')


Please check if it correspond to your urs.

I guess what I was asking was how to get the domain/subdomain info from places 
like models and settings -- i.e. places that have no connection to a request.

Still, I see a way through and will employ your suggestions.

Re: request.user objects in base.html

[Alan]

On your views.py, do something like:

@login_required

def readme(request):

return render_to_response('acpypi/readme.html', {'user': request.user})

I mean, your view has to pass the 'user' value to the template. I use this
very same scheme where all my pages extent base.html, so in my readme.html:


{% extends "base.html" %}
...

I hope it helps.

Cheers,
Alan

request.user objects in base.html

[izzy_dizzy]

Hi all,

I'm having a hard time on how to use request.user objects in
base.html. I know that we can use requestcontext to be able to render
request.user and its objects on a given template but I would like
someone help me to be able to use it on base.html like:

{% if user.is_authenticated%} You are currently logged in.{%endif%}

I also tried to use custom template tags but I can't get it right. Can
any one provide me a working custom template tag for this one?

Thanks!!

a different kind of file path field

[DrKayBee]

Hi,
I'm creating a task journal using django for personal use.

I'm creating an application wherein I require a CharField to store a
file location on a local drive. This is different from the FileField,
since I do not want to 'upload' the file to any different location on
my local drive, just to record a file url. What field must I use for
this? The FilePathField doesn't work for me because I want the
absolute location of the file to be user selectable, not restricted to
a pre-determined location. Ideally I would like a file chooser
dialog.

Do I need to create my own field or is there something I'm missing?

Thanks!

Re: Getting url/host/domain info in settings.py

[Tom Dyson]

Settings can be altered at runtime - the middleware code I referenced
does this - but the Django docs warn against it:

http://docs.djangoproject.com/en/dev/topics/settings/#altering-settings-at-runtime

I'd recommend using middleware to set the subdomain in the request
scope, e.g.:

http://www.djangosnippets.org/snippets/1119/

Transactions not working

[thomasbecht...@googlemail.com]

Hi all,

Problem: I want to use Transaction to save data to a postgresql-db.
Error: IntegrityError: doppelter Schlüsselwert (double keyvalue)
verletzt (harm) Unique-Constraint
»measurements_loggerdata_logger_id_key«

My Model looks like this:

class LoggerData(models.Model):
  logger = models.ForeignKey(Logger)
  datetime = models.DateTimeField(db_index=True)
  class Meta:
unique_together = [('logger', 'datetime')]

Now i read from a file measurement-data. It should be possible to read
the same file as often as i want, but maybe, there is some new data
append to the file. So the problem is, that inside of the file, there
is some old and some new data. The old data should not be written to
the DB, the new Data should be writte to the DB.

My Method to write the data to DB looks like:

from django.db import transaction
obj = LoggerData(**params)
self.saveLoggerDataToDatabase(obj)

def saveLoggerDataToDatabase(self, obj):
""" Save a LoggerData Object to the Database. Use a
Transaction for this."""
transaction.enter_transaction_management()
obj.save()
try:
transaction.commit()
except(psycopg2.IntegrityError, psycopg2.InternalError), e:
self.logger.error(str(e.message) + str(line[0]))
transaction.rollback()#
transaction.leave_transaction_management()

I also tried it without  transaction.enter_transaction_management()
and with a decorator (commit_manually() ). I tried with activated
Middleware and without. Nothing worked for me.

I also tried to coment out the commit() statement. The strange thing
was, that i got the same error. I thougt, without the commit()
statement, the DB would not get touched.

have you any suggestions?

Thanks,
Tom

Assuming you are in your project dir, I think it has to be:

post_syncdb signal: Called several times

[Thomas Guettler]

Hi,

I read the docs for the sync_db signal:
   http://docs.djangoproject.com/en/dev/ref/signals/#post-syncdb

The signal gets fired several times. Since my app has several model classes.

But how can you know that the tabel for a particular model was just created?

Or do you need to write the callback method the way, that it can be called
several times (for example: check if change was already done before
changing something)

I would put a method on your entry class, something like is_hidden,
which would do the calculation and return a boolean. Then your
template can just call {% if entry.is_hidden %} as necessary.
