Re: how can i get all values of a field

[Lachlan Musicman]

No, that wouldn't work because Category looks like a var on Novel, not
a model in it's own right.

Novels.objects.filter(category="comedy") is how to get a distinct category.

To get the list of categories used, use distinct for a quick hack -
something like:

Novel.objects.order_by('category').distinct('category')

Cheers

The idea of anathematising all of a person’s good works because of
something else they said or did is just as alien and repellent to us
as our reaction is to someone who wishes Hacker News would die because
Paul Graham is kind of a dick sometimes. ... Sergey Bratus points out
that keeping works by “ideologically impure” persons out of public
view was instrumental to Soviet systems of social control. And as
@puellavulnerata acutely observes, a culture that encourages judging
people unilaterally, rather than judging their actions in context, is
one that allows socially-adept hierarchy climbers to decontextualise
their own self-serving cruelties as “necessary for the cause” and
stage witchcraft trials against the weirdoes on the margin.

Hi dota and java,

If your model for the categories is Category, you would use:

Category.objects.all()

Building and firing a web page as an action under admin

[Victor]

Django 1.6.4
I've built an application to manage a medical warehouse resorting exclusively 
to the admin interface and postgresql 9.3.
To put it in a nutshell, among other things I have an admin form using inlines 
that for each patient lists the medical items he/she has been given and the 
date of the delivery.
For a mere matter of control they would like to print (I mean to a printer) a 
concise report selecting the patients they are interested in and clicking on 
the "actions" field to, say, "Print a report". 
I use actions for other purposes with success and I can build views and the 
related url but now I don't know how to fire a webpage built with the selected 
item. 
Could you please give me some directions and suggestions?
Thank you
Vittorio

I'll be honest, I'm yet to find an asset pipeline that suited every use
case.

I've used django-pipeline in the majority of cases, but have also used a
custom pipeline tools (such as gulp.js and one off Python scripts) for more
complex requirements, such as compiling AS3 files as part of the pipeline.

If you find any better alternative to pipeline, let me know :)

Re: Model Objects and Updating db via XML

Django knows how to load data from json, xml, whatnot only if it knows
about the format. I don't remember
we considered Django native serialization/unserialization support (see my
mail on Python ML).

The thing is that, in your project, it seems like import is a "one time
thing". So maybe using a framework thingy like django-swallow or a custom
django's fixture thing is too much.

Anyway, here is the "getting started" document of django
swallow,
summed up below:

- Builder class: entry point for an import, this used among other thing to
trigger the import from command line.
- Mapper class: create "mapping object" for the input xml. Basically it
breaks down a xml into sub-documents (if it's rss/atom like xml) or a
single object if it's actually only one document, pythonize the xml data
and make it easily accessible as object properties... no heavy processing
of data or mapping to data already in the database. For instance, if you
have an identifier, that maps to a row in the database, you retrieve the
populator (see below) will retrieve the identifier as an integer or string
and convert it to a Django model...
- Populator class: it helps populating the target django model object. It
implements common operations, like «model.foo = mapper.foo» and other stuff.

The idea behind django swallow, is that an import is breaked down into
several steps:

- parse xml, and turn in into simple python object(s) with python types
(Mapper class)
- populate one django model instance (or several) with based on the data
from the first step (Populator class)

They are extra optional steps ;)

I'm not sure about what is the repository, but for instance you can create
a base mapper, which will populate a plain python objects from xpath and
then the populator can be as simple as:

class Populator(BasePopulator):


_fields_one_to_one = None  # XXX: in this case None means map
every properties of the mapper object to the model fields with the
same name...
_fields_if_instance_already_exists = None
_fields_if_instance_modified_from_last_import = None



It's may seem kind of overkill. But when you have 5+ imports running
everyday, business critical, processing several dozen of files, for
different kind of documents it's helpful to know that the implementation is
built in a canvas, a framework, you know where to look for the code
implementing a behaviour depending on the behaviour... whether it is for
debugging or building new imports...

There is a full but simple example, importing items from an atom file:
https://github.com/liberation/django-swallow/blob/master/example/config.py

HTH,


Amirouche

Re: int() argument must be a string or a number, not 'datetime.date'

[MikeKJ]

*D'oh*  needed to reference back to the date model as in

qs = 
Booking.objects.filter(arrival_date__travel_date__exact=form.cleaned_data['arrival_date'])

arrival_date is a int id reference!!!

sorry and thanks to anyone who was looking at this

Dynamically updating field with JQuery

[Jason S]

Hi,
I'm sure this has been discussed to death, however the examples i've seen 
involve 3rd party django apps or are very complicated and I haven't been 
able to find a clear example which.I can repurpose.
I'm new to development so am building up a Django website to help grow my 
skills, but have a long way to go and its tough picking up Django, Python 
and JQuery at once.

I would like to show a simple form based off a model, where some fields are 
hidden.
The form includes a category and subcategory field. There is a one to many 
relationship between the fields.
I would like to dynamically update the form to either:

   - Show the hidden "subcategory" field, populated with the queryset based 
   on the selected category.
   - Just populate the subcategory field with a populated queryset based on 
   the selected category

If someone could give a quick example on using JQuery to achieve the above 
it'd be very helpful.
Thanks for any help you can spare.
J

Re: Why Django Apps Suck

[Delusional Insanity]

I've seen enough great reusable packages for Django.

I've also seen a lot of really bad packages and even have been forced to 
use bad apps in production, that you should really either fork or hack in a 
very strange way.

Some awesome packages:

- South https://pypi.python.org/pypi/South
- django-piston https://pypi.python.org/pypi/django-piston
- django-reversion https://pypi.python.org/pypi/django-reversion
- sentry https://pypi.python.org/pypi/sentry
- django-dbtemplates https://pypi.python.org/pypi/django-dbtemplates

Some of my own that in my concern are great and reusable:

- django-dash https://pypi.python.org/pypi/django-dash
- ska (see the contrib package for password-less authentication into 
Django) https://pypi.python.org/pypi/ska

It's just a matter of making the app reusable and flexible enough to adapt 
modifications.

In case anyone else ends up with same problem, I was using request.path

Ugh nevermind.

Yes it's a bug - but in my code.  I'll figure it out.

Django - Mysql datetime timezone naive and aware

[Gabriel]

Hello folks, I've found an abnormal behavior migrating a project from php - 
mysql to django 1.6.x - mysql and timezone naive to aware datetimes, I've 
posted my insights about it in stack overflow, if anyone can help will be 
more than welcome!

Many thanks!

Stackoverflow link -> 
http://stackoverflow.com/questions/23755968/django-mysql-datetime-timezone-naive-and-aware

Stackoverflow Post:

I'm involved in migrating an app from php - mysql to django - mysql, well, 
I've started migrating an inbox app which allows users to send messages 
1to1, after my first data migration (using a insert - select mysql 
statement) I proceed with some data migrations as follows.

   - I've tried to migrate messages statuses: in my "legacy" database the 
   approach used is using a bitwise field with integers suchs as 1 for 
   received, 2 for read, 4 for trash and so on, I've installed django-bitwise 
   to accomplish the same approach but I must migrate those integers to 
   strings like "RECEIVED", "READ", "TRASH", ... since I have millions of rows 
   I cannot use the ORM with an objects.all() and I've had decided to go month 
   by month.

If I try to count messages by month using the following ORM statement:

Message.objects.filter(sent_at__year=2011, sent_at__month=1).count()

It returns 0
--

If I count it directly using the following SQL statement it returns the 
correct number:

select count(*) from inbox_message where year(sent_at) = 2011 and 
month(sent_at) = 1;

Result is 64955
--

After a little bit of digging into Google and Stackoverflow it seems to be 
something related to timezone naive datetimes, so I've tried the following

settings.USE_TZ = FalseMessage.objects.filter(sent_at__year=2011, 
sent_at__month=1).count()

Now It returns 64955 hooray!
--

Known this, I've started to convert 'sent_at' from timezone naive to 
timezone aware, my first approach was to apply the CONVERT_TZ mysql 
function in my insert - select statement but it produces the same result, 
since my original data source is on UTC+1 timezone I've decided to fix this 
as well using:

convert_tz(sent_at, '+01:00', '+00:00')

I'm not using named timezones because I didn't installed the mysql timezone 
tables (as docs says)

After that I've tried to use django.utils.timezone.make_aware to make my 
datetimes timezone aware using a simple python script... nothing changes, 
still having zero when USE_TZ=True, the script looks like:

from django.utils.timezone import is_naive, make_aware, utc
settings.USE_TZ = False
messages = Message.objects.filter(sent_at__year=2011, sent_at__month=1)for m in 
messages:
settings.USE_TZ = True  # Set it to true to avoid errors when datetime 
becomes timezone aware
if is_naive(m.sent_at):
m.sent_at = make_aware(m.sent_at, utc)
m.save()

Same results, filtering by year and month returns 0 elements.

Just to let you know, filtering just by year seems to work okay.

Thanks in advance
