Re: PyDev users: how do you manage tabs?

[Chris Lawlor]

I have the same problem in Komodo Edit - although I the whole filename
does show up in the window title I never think to look there. Anyway,
I partially solved it by adding a comment at the top of the file for
what app the file is for, so I'll see what I'm working on right there
in the editor window.

Re: PyDev users: how do you manage tabs?

Wayne I can't thank you enough!!

As the author notes, the posted code is not cross-platform. I
incorporated the fix recommended in the comments and posted here for
anyone else that might want it:
http://dpaste.com/hold/62468/

works fine on my windows machine, haven't tested on my Linux dev box
yet.

Re: Installing django

[Chris Lawlor]

Just to see what all the fuss is about, most of that video is the guy
configuring his particular application. The actual Django install is
very straightforward.

Re: Format fields in list, but keep sortable?

[Chris Lawlor]

You could add a field to store the calculated size, and override the
model's save method to perform the necessary calculation. Something
like:

def save(self, force_insert=False, force_update=False):
self.size_formatted = self.width * self.height // or whatever your
calculation actually is
super(ModelName, self).save(force_insert, force_update)

Be sure to replace 'ModelName' with the name of your model.

Re: contrib.auth.views - n00b question

[Chris Lawlor]

You probably don't want to reference the login view to /accounts. You
probably mean to do this:

(r'^accounts/', include ('django.contrib.auth.urls'),

That will map /accounts/login to django.contrib.views.login, /accounts/
logout to django.contrib.views.logout, etc.

In general, when using an app, you'll add a line to your base URLConf
that includes that app's urls module.

Re: newbie question

[Chris Lawlor]

Also, one way to integrate scripts like this is to write them as
django management commands, so you can run them as 'python manage.py
yourcommand'. Management commands are pretty well documented in the
django docs, you should have no trouble finding enough info to get
started.


Again, good luck

Re: apache reload

One approach is to set "MaxRequestsPerChild" to one, basically forcing

way to accomplish this, but almost certainly the most simple to
implement.

Re: How to join a search on user and user profile

[Chris Lawlor]

You should be able to do something like:

UserProfile.objects.filter(gender='female',
user__email='some...@mail.com')

Note the double underscore notation, which let's you access attributes
of the related model. This example assumes that UserProfile has a FK
field to User which is named 'user'.

Re: How do you write a django model that can crunch numbers and automatically populate another field with results?

[Chris Lawlor]

Also, you can use aggregate queries to get the tfidf max and min:

from django.db.models import Max, Min

Party.objects.all().aggregate(Max(tfidf'))
{'tfidf__max': 0.5 }

Re: Ranking Queryset

[Chris Lawlor]

If you can use 
.annotate()to
 calculate the rank, you can further filter / order the annotation 
results.

An example:

class Book(models.Model):
title = models.CharField(max_length=120)
...

class Vote(models.Model):
user = models.ForeignKey('User')
score = models.IntegerField(choices=((-1, 'Thumbs Down'), (+1, 'Thumbs 
Up')))
book = models.ForeignKey('Book', related_name='votes')


To rank the Books by the sum of thumbs up and thumbs down votes, you could 
do the following:

Book.objects.all().annotate(rank=Sum('votes__score'))

Each object returned by this QuerySet will now have a 'rank' attribute, 
which is the sum of the Vote scores. You can then filter or order by rank. 
For example, to retrieve only books with a positive overall rank:

Book.objects.all().annotate(rank=Sum('votes__score')).filter(rank__gt=0).order_by('rank')

Hope that helps.

* Code isn't tested

Re: need help on set_password()..............

[Chris Lawlor]

If you're using the User model from contrib.auth, you can simply use 
User.objects.create_user(username, email=None, password=password). This 
will create a new User object, and then call set_password()

# forms.py
class RegistrationForm(form.Form):
username = forms.CharField()
password = forms.CharField(widget=PasswordInput)

# views.py
def register(request):
if request.method == 'POST':
form = RegistrationForm(request.POST)
if form.is_valid():
# UserManager.create_user() is a convenience method for 
creating a new user, and calling user.set_password()
user = User.objects.create_user(form.cleaned_data['username''], 
password=form.cleaned_data['password'])
else:
form = RegistrationForm()
return render(request, 'your_template.html', {'form': form})

If you're not using Django's User model, you could use one of the password 
hashers from contrib.auth.hashers to create the hashed version of the 
user's password. Something like:


class MyUser(models.Model):
username = models.CharField(...)
password = models.CharField(max_length=128)

# views.py

from django.contrib.auth.hashers import PBKDF2PasswordHasher as hasher

def register(request):
...
user = MyUser.objects.create(username=form.cleaned_data['username'], 
commit=False)
salt = hasher.salt()
user.password = hasher.encode(form.cleaned_data['password'], salt)
user.save()


Or better yet, move the user creation logic into a manager, similar to the 
design of UserManager:

class MyUserManager(models.Manager):
def create_user(self, username, password):
user = self.model.create(username, commit=False)
salt = hasher.salt()
user.password = hasher.encode(password, salt)
return user

class MyUser(models.Model):
...
objects = MyUserManager()

With that, you can do user = MyUser.objects.create_user(username, password).

Looking at the source code for 
contrib.auth.modelsand
 
contrib.auth.hashersmay
 prove helpful.


If you have existing password data that you need to convert to a hashed 
format, you might consider using a South data migration. Conveniently, the 
tutorial on data migrations uses this use case as an example: 
http://south.readthedocs.org/en/latest/tutorial/part3.html#data-migrations.

(Consider all code to be untested pseudo-code)

Re: Django development running on 127.0.0.1:8000 not accessible from same machine

[Chris Lawlor]

Jirka,

Is your app possibly doing a 301 (Permanent) redirect to www.* ? Or 
possibly some other app you were working on recently? Browsers will cache 
301 redirects and automatically do the redirect WITHOUT making the initial 
request to 127.0.0.1, so if some project you were working on issued that 
redirect at any point, it will keep doing it, even if your current project 
doesn't issue a redirect. Try clearing your browser's cache.

Chris

Re: Am I using static files "wrong"?

[Chris Lawlor]

Micah,

Here's a summary of how staticfiles works:

1. You place your static files, which are under version control, in 
app/static folders, or any directory defined in STATICFILES_DIRS. This is 
configurable, and works very similarly to how templates are placed in a 
project. The important thing to note is that your 'source' static files can 
be scattered among several directories, all of which are under version 
control.
2. You define STATIC_ROOT, which is the absolute path to some directory on 
your filesystem where you want the static files to be collected 
to. STATIC_ROOT would not be under version control, although some 
developers like to add an empty '_static' folder to version control so you 
don't have to manually create the STATIC_ROOT folder when deploying the 
project to a new machine.
3. Running 'collectstatic' collects all of your static files, and copies 
them to STATIC_ROOT.
4. You configure your production webserver to serve '/static/' (or whatever 
STATIC_URL is set to) from STATIC_ROOT. If you add staticfiles_urlpatterns 
to your URL config, the development server will serve your static files if 
DEBUG=True.


The template context processor django.core.context_processors.static, which 
provides STATIC_URL, is not deprecated. Feel free to use either that or the 
template tag.


Hope that helps,

Chris

Re: Calling Jquery or javascript function based on an if condition

[Chris Lawlor]

A slight variation of this approach is to map some Django template context 
info to Javascript variables in one of your templates, making that data 
accessible to your compressed / minified JS code:

# in a template, "base.html" perhaps..


window.DjangoContext = {
  userLoggedIn: {{ user.is_authenticated|yesno:"true,false" }}
}


Note the use of the 'yesno' filter to convert "True" to "true" to match JS 
syntax.

Now you can access DjangoContext.userLoggedIn anywhere in your JS.


** It's important to note that users can modify any JS variable they wish, 
so don't rely on something like this for security **

Re: django development server timeout too quick

[Chris Lawlor]

Hadi,

What is your SESSION_COOKIE_AGE set to? This setting controls session 
expiry. The default is 2 weeks. If you are not setting SESSION_COOKIE_AGE, 
check that your code is not calling request.session.set_expiry() anywhere.

For light use, the default session backend (db) should meet your needs. 
Have a look at the warning 
here: 
https://docs.djangoproject.com/en/dev/topics/http/sessions/#using-cached-sessions
 
(Note link to dev version of docs). Using the cached_db session engine with 
a file based cache isn't buying you anything but extra complexity.

Re: Template Caching with Messages

[Chris Lawlor]

V,

You're exactly correct - make sure you only cache what you actually want 
cached : ) Anything that should only be visible for one page view isn't a 
good candidate for caching. If your page has any sort of content that is 
specific to the current user - login state, etc., you probably don't want 
to cache that part of the page either, if there's a chance that a user with 
a different state can hit the same template.

Caching bugs can be subtle. I'd suggest writing some comprehensive 
integration tests for anything more than the most trivial caching 
strategies.

Chris

Re: linux or windows

[Chris Lawlor]

Django itself is completely platform agnostic. Years ago I used to develop 
on Windows, and typically where I would run into problems was trying to 
find binaries for third party libraries like PIL and psycopg2. They'd 
usually be available from somewhere or another, thanks to some kindhearted 
soul who managed to build them and shared the binaries online, just 
difficult to track down. Building from source is certainly possible, but 
setting up the correct toolchain for a successful build is a non-trivial 
endeavor. This may have improved in the last few years though, I couldn't 
say.

Also (and this isn't directly related), the awesome virtualenvwrapper, 
which is a core part of my workflow nowadays, is not available in Windows, 
Virtualenv itself does work on Windows though.

Personally, I think it is best to develop on a system as close to your 
production environment as possible. It's certainly possible to develop on 
Windows, and deploy to Linux (or vice-versa), but you increase your risk of 
encountering bugs that only occur on one platform, which can be difficult 
to troubleshoot.

Developing Django Apps - best practices?

[Chris Lawlor]

All,

I'd like to get some feedback from the community on the current best 
practices for developing standalone Django apps. To clarify, by 
'standalone' I mean a codebase that is just the application itself, to be 
installed into a Django project via setup.py / pip, not working on the app 
directly within a Django project. It seems that people love to discuss 
ideas related to projects (layout, settings, etc.), but I haven't seen much 
discussion focusing on app development.

For example, do you have some boilerplate that you use when starting a new 
app? For projects, we have project templates, but as far as I'm aware there 
is no particular application boilerplate that is in wide use.

Here are some other questions you might consider:

* How do you organize tests? Do you include a test project?

* How do you link your standalone apps to your current projects? Install 
via pip, add the app src directory to your PYTHONPATH, something else?

* What tools / libraries / other resources do you find most useful?

There is some documentation on the topic here (
https://docs.djangoproject.com/en/dev/intro/reusable-apps/), which is a 
great start, but it glosses over deployment and completely ignores testing.

My goal here is simply to start a discussion. Hopefully, if some general 
consensus emerges, we might identify some ideas that could possibly be 
documented elsewhere, whether we inspire a blog post or add to the Django 
documentation itself.

Thank you,

Chris

Re: django , python and ides

Joey,

Would you be interested in sharing your virtualenvwrapper setup? I assume 
you're using some custom postactivate hooks, looks nice.

Re: Passing variables to css file in django

Re: Parsing feeds that are imported

[Chris Lawlor]

I've not used the django community aggregator, so I'm making some
assumptions about it's functionality. If that app were to emit a
signal for each feed entry that it processed, it would be fairly
simple to write a signal handler that would create the associations
that you want. With this approach, you wouldn't need another cron job,
your processing would be done at the same time as django community
aggregator's.

If you do need to do some manual feed parsing, you might try using the
Universal Feed Parser python module: http://feedparser.org/. It's
specifically designed for parsing RSS / Atom feeds, and so may be
somewhat more useful than BeautifulSoup.

Re: 3rd party Apps in Django

+1 for using virtualenv. Indispensable for working on more than one dingo

take a look at virtualenvwrapper. It makes working with virtual environments 
practically painless.

Re: more than one querys LIKE in the same field

[Chris Lawlor]

Not to second guess your intent, but are you sure you don't mean to OR
the two? Your current SQL / Django query will only return tags that
have both 'candy' and 'milk' in the tags string.

If you do want to OR the queries, you can use Q objects:

from django.db.models import Q
table.objects.filter(Q(tags__icontains='milk') |
Q(tags__icontains='candy'))

Also note that, if you're using sqlite, case-insensitive string
lookups are not supported (see 
http://docs.djangoproject.com/en/dev/ref/databases/#sqlite-string-matching).

Hope this is helpful,

Chris

Re: Load file into a FileField

[Chris Lawlor]

Liriela,

AFAIK it is not possible to programmatically populate a file input
field, due to the many security exploits this would enable. If it were
possible, it would be trivial to write a malicious script that would
upload any file from a user's PC, so long as you knew the path.

There are browser-specific exceptions, for example, in Netscape-based
browsers you can call
netscape.security.PrivilegeManager.enablePrivilege("UniversalFileRead")
(see 
http://www.mozilla.org/projects/security/components/signed-script-example.html).
This needs to be called from a signed script, and I believe will still
trigger a pop-up dialog to confirm the enhanced permission request. I
imagine this might be more trouble than it's worth though.

As an alternative testing method, you might consider using curl. You'd
do something like:

curl http://localhost:8000/submit/test -F id_title=Test -F
id_email=em...@test.org -F id_file=@/path/to/test.txt -u
username:password

Note the @ symbol in front of the value for file_id - that tells curl
that the value is a file, not a string.

I've only really used this method when testing an API which returned
JSON data, which is easily viewable in the console. If your view is
returning HTML, you might pipe the output to a file to open in a
browser.

Hope that helps,

Chris

Re: loading the external css file

[Chris Lawlor]

Django doesn't server static files (like your CSS file) by default -
but you can configure the development server to do so:
http://docs.djangoproject.com/en/dev/howto/static-files/

Note that this has changed a lot in Django 1.3, so be sure to view the
correct version of that page for the version of Django that you are
using.

In production, you should almost always configure another server to
serve static files.

Re: ModelForm Field not display choice text

[Chris Lawlor]

Michael,

In one of my projects, I did something like this:


{% for field in rating_form %}
{{ field}}
{% endfor %}



$('#stars').children().not(":radio").hide()
$('#stars').stars({
cancelShow: false,
callback: function(ui, type, value){
ajaxVote(value);
}
});

function ajaxVote(value) {
$.ajax({ url: '{% url plugin-rate object.slug %}',
 type: 'POST',
 data: { rating: value },
 dataType: 'json',
 success: function(data){
var avg_rating = data['avg_rating']
var votes = data['votes']
$('#rating_display').html(avg_rating +" out of 5 (Rated " +
votes + " times)")
 },
});
}

The key to hiding the other form elements (like the labels) is the $
('#stars').children().not(":radio").hide() call, which basically hides
everything but the actual stars. If the use doesn't have JS enabled,
they should still see the radio buttons with the associated labels.

Hope that helps,

Chris

Re: loading the external css file

[Chris Lawlor]

If you don't have a staticfiles module, you most likely aren't using
Django 1.3. Make sure you select the correct version of Django when
viewing the docs, as things are often done differently in older
versions, but the doc pages usually default to the latest SVN release.
