Re: Javascript with built-in templates tags

That needs to be :
alert({{ selectedAreas.BC }});

Look at the documentation. This problem is fairly obvious if you do:
http://docs.djangoproject.com/en/dev/topics/templates/#variables

I'm not trying to be mean, but please look at the docs before you post
here, it wastes our time, and yours waiting for a response. Thanks!
We are more than happy to help, just please check the documentation first. ;)

Hope that works for you.

Django follows normal python import rules. So just lookup those to

Re: How to get rid of the 'u'? Seems to be everyhere :)

[Luke Seelenbinder]

As James said, spend some time with the Python basics.
Here is a good online book to checkout (free)
http://www.diveintopython.org/toc/index.html

Get a firm foundation in Python before attempting anything with
Django. That will help immensely.
I took a college-level python class before I started anything with
Django, it helped a lot.

Hope it helps,

I think your problem is just the spaces between the filters, try {{
mooman|safe|escapejs }}.
Other then that, as long as the mooman is set in the context... that
should work.

Re: Duplicate results using ORd Q queries

[Luke Seelenbinder]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Tom,

The reason it was returning dupes is simply you had multiple querysets
that matched some of the same items.
As for the while loop, it was malformed. It looks like an infinite
loop to me... I might be wrong; however, a for loop would have better
served you, e.g.,

films = []
for r in results:
#checks if instance already films list
#if it is, this is a dupe, do nothing
if not r in films:
#if not this is not a dupe, append to list
films.append(r)


that would have served the same purpose as the distinct method.

Re: Duplicate results using ORd Q queries

[Luke Seelenbinder]

Tom,

make your line read:
results = Film.objects.filter(
Q(title__icontains=q) |
Q(director__name__icontains=q) |
Q(actors__name__icontains=q) |
Q(screenwriters__name__icontains=q) |
Q(genre__icontains=q)
).distinct()

So just add the distinct method to the Q set. And then you won't need
the while loop at all.
Read: http://docs.djangoproject.com/en/dev/ref/models/querysets/#distinct

Hope that helps.

Re: Javascript with built-in templates tags

Wilson,

Are you referring to rendering JS with template tags, or actual
template tags in JS?

In the first case, you use them like any other template tag.
The second case is only possible if there is some JS library that uses
Django-like templates.

Re: Amazon Product Advertising API

Bryan,

I decided not to totally write a new module for it. I took pyaws, and
re-factored it to account for the secret key you now have to use with
requests.

If you want the new ecs.py from pyaws, I'll be happy to get it to you.
I'm not 100% sure it works, but for what I've used it for I think it
does. Any testing is 100% appreciated.

Vasil,

That will vary on what the apps you are using. If none of the apps
depend on django.contrib.auth, you won't need it, unless you want to use
the django admin (which depends on django.contrib.auth).

To fully answer your question, we would need to know what apps it is using.

Re: Django 1.1 returns 500 instead of 404 in non-debug mode

[Luke Seelenbinder]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1


Prabhu,

Let's establish the reason the 404.html doesn't show on a supposed 404
error; that is because every single request on the output you posted a
little while ago from the server is responded with a 500 error.
Something is fouled up with the views, or somewhere in the server process.

I'll look through and see if I can spot anything.

Good luck!

Re: Django 1.1 returns 500 instead of 404 in non-debug mode

[Luke Seelenbinder]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hey, I think I located your problem.

In file invoicy / guidy / urls.py

You should change the first url pattern to read:
url(r'^/$', 'guidy_default', name='guidy-default'),
instead of:
url(r'^$', 'guidy_default', name='guidy-default'),

That should fix your problem. What is actually happening is you are
raising 500s on 404s. That's why the 404 error page is not showing.

Re: dictionaries in template

[Luke Seelenbinder]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

You are overwriting the 'answer' key every time. So there is only one
key called 'answer'. Try editing it so you make the 'answer' key a list
of the 'attach_list's, that is one possible solution.

Or possibly do you mean to use if loops in the template since you are
only passing one object?

Re: [solved]Re: test if GET is "empty"

[Luke Seelenbinder]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

There is a more "pythonic" way to test, use request.GET.get(,
False)

e.g.:
if request.GET.get('q', False):
etc.

That tests the dict for the key 'q' if it's not there, it returns false.

I personally use Eclipse w/ PyDEV and web dev tools. I absolutely love

to it.

That being said, IDEs are really a matter of personal preference, I know
of a lot of people that just use vim. My recommendation is try out the

Re: Where are the admin app icons from?

Could you resize them simply with CSS?
CSS handles resizing quite well.

I did find one set of icons sized at 10x10 here:

But they are greyscale.

Re: Where are the admin app icons from?

[Luke Seelenbinder]

I think they are the FamFamFam Icon pack.

Yeah ... I know where the icons used in the admin app are.  And I'm
using them in my own app (which is derived from the admin app).  So I
was just trying to figure out if they came from some general package
of icons where there were more with the same look and feel.  Based on
Daniel's reply, it sounds like they were designed specifically for
django, or that I should talk to Wilson Miner about it. (Thanks,

I don't know where the Django ones came from (they may have been

icons I'm quite fond of the famfamfam

Look at the official caching documentation:

http://docs.djangoproject.com/en/dev/topics/cache/#the-low-level-cache-api

That should work for you

Re: Using Django's Cache

[Luke Seelenbinder]

That is entirely possible; however, it might slow down the rendering
of the template, because you simply have more to handle.

Re: How redirect lightweight webserver messages?

[Luke Seelenbinder]

That would depend on the OS you use.

If you use linux:  "python manage.py runserver >> example.log"
That will save the output in a file, instead of showing it on screen,
allowing you to have another webserver serve it.

Amazon Product Advertising API

[Luke Seelenbinder]

I'm working on a django project right now that uses the Amazon Product
Advertising API. I was using pyaws, but it is quite outdated and won't
be useful for the changes coming in the next month.

My first question is whether you know of any other python library for
it.
Second question, is there anybody willing to help me develop a new
python abstraction for the api.

I'm going to get started today with a new python api, if there is
anybody willing to help, drop me an email (lukeqsee at gmail), or just
reply to this message.

Thanks,
Luke

order_by function

[Luke Seelenbinder]

Can I order_by a function within the model? I know you can list them
in the admin inteface, etc. But can you order_by a model function? Or
would you have to write a custom piece of code to do that?

Combine QuerySets from two different child models

[Luke Seelenbinder]

the models are:

class Word(models.Model):
   ... some stuff...

   class Meta:
   abstract=True
class Noun(Word):
.. some stuff ..
class Verb(Word):
  ... some stuff ...

code:

nouns= Noun.objects.all()
verbs=Verb.objects.all()

words = verbs | nouns

I get an error saying: "Cannot combine queries on two different base
models."
is there anyway to accomplish this, the reason I don't want to do:

nouns= list(Noun.objects.all())
verbs=list(Verb.objects.all())

words = verbs + nouns

is I want to be able to run an order_by on the resulting list or
queryset

thanks,

Luke

Re: ManyToManyField with multiple model options

That was a typo. The error I'm getting is
"ForeignKey cannot define a relation with abstract class Word"
It is a ManyToMany through table, that's the reason it is ForeignKey

Re: Bug in Admin or in my model ?

[Luke Seelenbinder]

You need to specify your encoding in your models file.
Like: # -*- coding: iso-8859-15 -*-
Look at http://

explains.

ManyToManyField with multiple model options

[Luke Seelenbinder]

Basically, I want to allow a ManyToManyField to use any of a Model's
children, like this:

class Word(models.Model):
word = models.CharField(...)

class Meta:
  abstract = True

class Noun(Word):
   gender = models.CharField(...)
class Verb(Word):
   irregular = models.BooleanField(...)

#Here is where I need the help
def WordStats(models.Model):
   # I get an error saying
   word = models.ManyToManyField(Word)
   stats = ...

Is there anyway to accomplish this? Without writing separate models
for each word.

Thanks,
Luke  S.

Foreign Key with a default key

[Luke Seelenbinder]

I'm am trying to make a ForeignKey with a default value.
But when I save i get a "invalid literal for int() with base 10: 'Stat

right   =   models.IntegerField(default=0)
wrong   =   models.IntegerField(default=0)

def percent_right(self):
return (float(right) / total) * 100

class Noun(models.Model):

word=   models.CharField(max_length='50',
unique=True)

definition  =   models.CharField(max_length='100',
default=Stat())

definition_stats=   models.ForeignKey(Stat, default=Stat(),)

GENDER_CHOICES  =   (
(True, 'Masculine'),
(False,'Feminine'),
(None, 'Neuter'),
)
gender  =   models.BooleanField(blank=True, null=True,
choices=GENDER_CHOICES)
gender_stats=   models.ForeignKey(
Stat,
default=Stat(),
related_name='gender_stats',
)

plurality   =   models.CharField(max_length='50',)

class Verb(models.Model):
word=   models.CharField(max_length='50',

definition  =   models.CharField(max_length='100',)
