For the record, the right command is pip install -e git+
https://github.com/django/django.git#egg=django

Re: import django fails, what should I look at?

[Andre Terra]

You should use pip to install django.

This is how I go about it, from a fresh install.

mkdir ~/virtual
mkdir ~/projects
pip install virtualenv # unnecessary in python 3.3+
pip install virtualenvwrapper # use this. it will make your life much
simplerecho "export WORKON_HOME=$HOME/virtual" >> ~/.bashrcecho
"export PROJECT_HOME=$HOME/projects" >> ~/.bashrcecho "source
/usr/local/bin/virtualenvwrapper.sh" >> ~/.bashrc
source ~/.bashrc

After that, create your first virtualenv using mkvirtualenv foo, activate
it using workon foo, and deactivate it with deactivate.

Install packages using by issuing pip install commands, so if you want
django, you can use pip install django for the latest release or pip install
-e git#https://github.com/django/django.git for the latest development
version.

You might want to check the docs for virtualenv, virtualenvwrapper and pip.
You may also benefit from using yolk (python package) to check what you
already have installed in each virtualenv..

Best of luck!

Re: How do I use mathematical calculations on my forloop Article/Publication list?

[Andre Terra]

Take a look at the docs for aggregation and annotation and using F
expressions in them. I just skimmed over your email, but there might be
something useful to learn there.

https://docs.djangoproject.com/en/dev/topics/db/aggregation/
https://docs.djangoproject.com/en/dev/ref/models/queries/#f-expressions

Also, is there a reason why you're not using class based views?

As per the current docs[0], you need to provide a dotted path to your model
in the form app.ModelName when defining a ForeignKey.

So try this instead:

GalleryId = models.ForeignKey('galleryview.Gallery',
verbose_name=_('Gallery Id'), related_name='Gallery_Id',blank=True,
null=True, help_text=_("You can associate a photo gallery to this event
here."))

If you don't mind me saying, 'galleryview' is a funny name for a django
module, considering how we use the name 'view' for something else entirely.

Re: I really about to give up Django

[Andre Terra]

*Non sequitur*.

Obscure variable names can happen regardless of the coder's language
choice, and most definitely do not encourge the use of one's native tongue.
As others have said in the thread, if you're writing *in English* to ask
for help, you should probably code in English as well.

It's not a stretch to say that the English-speaking community of django
developers is much larger than that which speaks any other language, so
it's all about trying to help yourself.


Cheers.

Re: JSON or YAML?

[Andre Terra]

It depends on where your data is coming from. YAML has less cruft in it, so
if you're writing your own serializer you can consider it to have an
advantage over JSON.

OTOH, many applications can already export to JSON, so you can leverage
that if that's the case.

Finally, If you're writing anything by hand, YAML is much faster.

make sure the folder containing wikicamp is inside your PATH so you don't
get import errors. make sure there's an __init__.py inside it.

perhaps you could debug the import error like this:

$ ./manage.py shell
>>> import sys
>>> print '\n'.join(sys.path)
>>> import wikicamp
>>> from wikicamp import wiki


In the future, please post an entire traceback along with your question.

Re: I really about to give up Django

[Andre Terra]

For the record, it's considered a good coding practice to keep everything
in English, including classes, functions and variables. This way it's
easier for people to help you.

Secondly, your Filhos model should really just be Filho.

Finally, don't use obscure names like Brinq. Instead, prefer the verbose
'Brinquedo'.

So I suggest renaming things like this:

Pai -> Parent
Brinq -> Toy
Filhos -> Child

and so forth.

You can use django-mssql[0] as a backend, and then either use the ORM as

Re: rich text editor

[Andre Terra]

It seems you are asking two completely unrelated questions:
1. to allow users to add some form of tags into their code for richer
submissions.
2. to have a different css for each user

One possible answer to #1 is BBCode, as I described. Question #2 is
something altogether. Do you want each user message to appear differently?
Is that supposed to be customizable to the degree of css? Are you just
switching colors? How much are you going to let the user style their
messages? BBcode should be anough to allow them to add bold, italics,
links, pictures, etc. If you just want that, there's no need to have a
separate css for each user. Instead, just follow my instructions below.

I'm not sure how django-bbcode styles the rendered text, but my
step-by-step investigation would be:

1. Install django-bbcode
2. Make sure you have a view somewhere with an input and go to that URL.
This would possibly be a very simple view with a textarea where you'd type
something in and see the rendered output.
3. Send the textarea back to the template in a variable (called, say,
stuff) and render it with {% bbcode stuff %} in the template.
4. Use firebug, google chrome's inspector/developer tools to inspect the
css that's applied to the rendered text
5. Make changes to yourcurrentcssfile.css to include styling for the BBCode.
6. GOTO 2
7. ???
8. Profit!!!

I hope I understood your question well enough. Good luck!

Re: Django Basics

[Andre Terra]

You really *should* use a database, even if you use SQLite just for
learning. SQLite saves a .db file to your hard drive, but it's a RDBMS like
many other, albeit in simpler form.

Take a look at the tutorial[1] and if you have any questions, try googling,
asking here or on stackoverflow[2]

Re: Django with 2 subapps with same name

[Andre Terra]

Despite possibly working with different app_labels, I believe the point
still stands that if the storage and invoice apps share a lot of
functionality among vendors, they should just be 'invoice' and 'storage'
and allow for pluggable companies.

Re: Django with 2 subapps with same name

[Andre Terra]

Granted this structure doesn't seem reasonable. Each manufacturer shouldn't
be a separate app, but rather "backends" to generic storage or invoice apps.

So you only need
INSTALLED_APPS = (
# ...
'storage',
'invoice'
)

And then work from there. The apps themselves should be able to register
and handle different backends. Take a look at what django-registration[1]
does!

Isn't a ModelChoiceField[0] what you need? Just customize the queryset
attribute to restrict the available choices. My django-fu is a little
rusty, but IIRC you can define fields at runtime by subclassing __init__
and extending self.fields, which is a dict.

Re: Admin pagination not digg-style

[Andre Terra]

Override the default template and add a for loop with {%
forloop.counter %}'s from 0 to max-pages or whatever the variable is
called.

Assuming you're talking about the change form, please see this:
http://stackoverflow.com/a/3729995/447485

Otherwise you can still probably work from the info provided there.

Re: Navigation Bar

[Andre Terra]

In my last project I created a template tag that would take an app name as
an argument and build the links according to that user's permissions for
the links in that app. This made the template easier to read at the cost of
having to write the function and learning how it worked. Since I was the
only one in the project, I didn't have to worry too much about that, so it
was just a matter of using {% menu 'profiles' %} and {% menu 'blog' %}, for
example.

I don't know if this is design pattern is The Right Way (TM), but It Just
Works (TM).

You can find documentation on writing custom tags here:
https://docs.djangoproject.com/en/dev/howto/custom-template-tags/

About the asterisks, please checkout this link:
http://stackoverflow.com/questions/4306574/python-method-function-arguments-starting-with-asterisk-and-dual-asterisk

the difference between dict['key'] and dict.get('key', 'something') is that
the second doesn't raise a KeyError exception when 'key' isn't in the dict;
instead, it returns 'something'. this allows for shorter code. please
compare:

try:
max_retries = config['max_retries']
except KeyError:
max_retries = 10

versus

max_retries = config.get('max_retries', 10)

Re: Kindly help for an interview with Google on python django

[Andre Terra]

I don't have any experience in interviews for developer positions, but I
have general job interview tips that you might like.

First, get to know your resumé. This is my #1 advice. Interviewers usually
want to know why you made your decisions. What was the reason behind
picking this or that school? Why did you apply to your last job? And why
did you want to leave the company before that? Basically, anything on your
resumé is fair game, and while you may not have made completely rational
choices at all times (we were all 18 at one point), your story should be
consistent.

Secondly, get to know yourself. Know what motivates you, why you want to
apply for this position (this is **paramount**) and what your expectations
are coming into the new job. Do you admire the company values, mission, or
goals? As a developer, not a consumer, how are you going to keep yourself
motivated after the honeymoon months in the new job? Are you able to work
in a fast-paced environment? What values do you consider especially
important so that you will strive to uphold while at Google? Innovation?
Transparency? Collaboration? None?

Finally, in order for you to be hired the interviewer should be able to
conclude you a) can add to the team and organization in general; b) are
able to actively engage yourself in order to perform at an excellent level
throughout your stay at the company; and c) Google specifically and this
position in particular are the best match to your ambitions at this point
in life, which is why you are

Re: Long url parameter in GET request locks python

[Andre Terra]

I posted this answer on SO and thought I should share it here for the
benefit of other and future readers:

--

 The accepted answer is spot on about the regex, but since we're discussing
optimization, I thought I should note that the code for checking whether a
project exists could be modified to generate a much quicker query,
especially in other contexts where you could be counting millions of rows
needlessly. Call this 'best practices' advice, if you will.

p = Project.objects.filter(projectName__exact = aProjectName).count()if p > 0:

 could instead be

if Project.objects.filter(project_name__iexact=aProjectName).exists():

 for two reasons.

First, you're not using p for anything so there's no need to store it as a
variable as it increases readability and p is an obscure variable name and the
best code is no code at
all
.

Secondly, by This way we only ask for a single row instead of saving the
results to the queryset cache. Please see the official Queryset API
docs
, a related question on Stack
Overflow
 and the discussion about the latter on the django-developers
group
.

Additionally, it is customary in python (and Django, naturally) to name
your fields lower_cased_separated_by_underscores. Please see more about
this on the Python Style Guide (PEP 8)
.

Re: Hierarchy Model

[Andre Terra]

I recommend using django-mptt. I can't link to it cause I'm writing on my
phone, but it's easy to find it on Google.

Also, your foreign key should target self rather than Employee, IIRC.

Re: from future url -- argh

[Andre Terra]

I was having the same problem, but with the development version (that is,
1.4+, or soon to be 1.5).

Just remove the {% load url from future %} because the future is NOW! :O

The old {% url %} tag has apparently been deprecated, but I can't find any
notes on this change after 2 mins of googling.

Let me know how it goes.

Re: OpenSource IDE with debugger capabilities of PyCharm

[Andre Terra]

"AFAIK" implies "I might be wrong", but.. sure.

Template Debugging threads in django-developers:
https://groups.google.com/forum/?fromgroups#!searchin/django-developers/template$20debugging


Efforts in better template debugging, none included in core:
https://github.com/codysoyland/django-template-repl
https://github.com/t0ster/django-debug-template


And if you were instead referring to my comment that there are threads
aplenty regarding IDEs, then:

Re: OpenSource IDE with debugger capabilities of PyCharm

[Andre Terra]

No IDE recommendations, please!

There are many threads regarding that, so please search around, OP.

As for template debugging, this is currently a limitation in Django itself
AFAIK, but efforts are being made to improve the situation.

Re: Python IDLE

[Andre Terra]

For one thing, I don't know of anybody who uses IDLE as their editor for
writing complex code like when developing a website with Django.

You can always type 'python manage.py runserver' instead of just 'manage.py
runserver' to make sure python is the program that's opening your .py file.

It seems like you have a problem with your file associations. To fix this,
go to the registry (Start Menu, Run, regedit) and browse to:

*HKEY_CLASSES_ROOT\Python.File\shell\open\command*

You should have a string there named '(Default') and its value should be
exactly this (including quotes): *"C:\Python26\python.exe" "%1" %**

You could have a different python path depending on your installation (say,
C:\Program Files\Python27), but you get the gist. Don't forget the quotes
and the trailing %*

Google for Django Audit Log and/or Audit Trail. While some of the packages

Re: Generic views create_object and prefill form data?

[Andre Terra]

For the record, you could go even further (and you may already have), and
make the get_initial part of a WebsiteMixin so that you can reuse it in
other views without having to repeat yourself.

Solved it by migrating to the class based generic views, then fed
initial form data to the constructor of the form by overloading
get_initial on the view class.

Re: Avoid verbose_name HTML escaping in admin

[Andre Terra]

I'm only guessing, but I think the escaping is being done at rendering time
by the template itself. Take a look at the default admin templates and
check the docs for an explanation on how to override them with your own.

Protip: do not edit the original files!

Django has a tendency of making you write really long lines, but I guess
you could break it into smaller chunks to improve readability.

logs = Log.objects.distinct('thing__id').order_by('thing__id',
'-modified_on')
related = logs.select_related().filter(thing__deleted=0)[:20]

Re: Comparing QuerySets

[Andre Terra]

Not sure if this is efficient, but you can try wrapping the values_list in
a set() call.

>>> set(ids1) == set(ids2)

True

>>> set(ids1) & set(ids2)

set([1])

>>> ids3 = set([])

>>> r = set(ids1) & set(ids3)

>>> r

set([])

>>> len(r)

0

Re: Difficult setup on Suse Linux

[Andre Terra]

There's a chance you have a logging module in your PATH that is shadowing
the default package.

Did you create an app or project named logging by any chance?

Ideas:
- From an interactive python shell, import logging and check
logging.__file__

In my Ubuntu install, I get:
/usr/lib/python2.7/logging/__init__.pyc

- Install virtualenv and create an environment using the --no-site-packages
and install nothing but Django. Try running it from there and see what
happens. Ideally, you'll want to use virtual environments always.

I'm hoping one of these solutions will help, but I'm really just guessing.

Re: Problem using django-admin.py in a virtual environment

[Andre Terra]

When you type 'django-admin.py foo' in a command prompt, windows will use
the system wide python install which is what is associated with the .py
extension. In order to avoid this, you must call 'python django-admin.py
foo'.

If you don't like having to type 'python' before calling a script, you can
alter your virtualenv activate script so that window's file association for
Python files gets changed when a new environment gets activated. This has
the downside of not reverting the association when you close a prompt
without properly deactivating (by typing 'deactivate'), but I still like
it, so there's a how-to below.


In order to tell the virtualenv to use your virtual python install when
calling file.py directly, you need to modify the activate.bat script and
add the following line somewhere in the beginning (after @echo off):

FTYPE Python.File="C:\Environments\django1.3\Scripts\python.exe" "%1" %*

Then add a line to revert this association change in deactivate.bat
(located in the same folder):

FTYPE Python.File="C:\Python27\python.exe" "%1" %*

I did my best to guess the paths, but you might have to adjust them
appropriately.


Hope that helps!

AT

Re: dynamically adding form fields

Hi Matt,

Search the docs for inlines, inline formsets and inline formset factories,
and you'll find exactly what you need [0].

Read them carefully cause it's easy to make mistakes and debugging inlines

Good luck and happy coding.

Re: Profiling Django (WAS Django database-api)

[Andre Terra]

Hey Javier,

Thanks for the reply. My problem with the logs in the past was that they
tended to make the task even slower (due to recursion) but I guess that's
probably because I didn't call the logging from the appropriate places in
the code.

To make things a little more complicated, the task involves writing a large
amount of data to a temp database, handling it and then saving some
resulting queries to the permanent DB. This makes it a tad harder to
analyze what goes on in the first part of the code.

I'll try logging again over the weekend and see how that works.. I just
wish there were third party apps and tools for debugging this sort of
problem.

Thanks again for your input.

AT

Re: Need help

[Andre Terra]

It could be a regression bug.

To be honest, I don't see a reason why '' should become 'localhost'
automagically. I'd much prefer if users were forced to write 'localhost'
rather than having Django do it (and fail) for them.

Explicit is better than implicit.

If you haven't yet, please file a bug report:

Profiling Django (WAS Django database-api)

[Andre Terra]

While I know of the two methods mentioned by Anssi, I've often wondered how
to profile my code from a project level.

I have some complex and database intensive asynchronous tasks running under
celery which take a LONG time to complete and I'd just love to be able to
keep track of the queries they generate in order to optimize and possibly
remove the biggest bottlenecks.

"Real time" updates would be great, but I can settle for after-the-fact
logs. I know of django-debug-toolbar [0] but since these aren't happening
in a view, I'm not sure that app can help.

Any suggestions? Thanks in advance!

Re: is doing text manipulations in django's template faster than doing same in views

[Andre Terra]

If you're doing a lot of operations with your data, there's a chance it
should be moved to the view. The template should usually be restricted to
defining *how* data gets displayed, whereas the view defines *what* your
data is.

To make things easier, create a free host redirect on no-ip.org[1] and name
it something like 'mydjangoserver.no-ip.org', then install the No-IP
service for automatically updating the redirect to match your current IP
(on a defined interval, which I usually set for 30 mins). This way you can
always point to http://mydjangoserver.no-ip.org regardless of which network
you're currently on. Helps if you're on the go often, or if you've got a
dynamic IP (my original problem back when I started using it).

Re: ANNOUNCE: Django 1.4 released

[Andre Terra]

Hooray!

Congrats to everyone involved, especially all that worked on bringing
timezone support to this increasingly amazing web framework.

I don't mean to nitpick but a minor detail in the release notes requires
some attention:

"Django does not support Python 3.x at this time. At some point before the
release of Django 1.4, we plan to publish a document outlining our full
timeline for deprecating Python 2.x and moving to Python 3.x."

Have we got a timeline yet?

Re: Is there a place for new Django specialized hosting?

[Andre Terra]

Forgive me if I sound pessimistic, I'm just a hobbyist developer offering
my most sincere 2 cents.

There are many services that offer similar features and sometimes even
more. From a business perspective, the only way to thrive in this market is
by having technology that provides competitive advantage and through
marketing aimed at receiving endorsement from trendsetters in the web
development field.

Google ep.io, gondor, apphosted, djangozoom, heroku,
cloudfoundry.com(built by a former Google/Microsoft engineer) and
others.

Considering these have already launched or at least reached beta stage,
you're off to a tough start if you do go through with the plan.

AT

Re: using forloop.counter to access data

You could always try writing a custom template tag or filter as someone

Re: Preventing JOIN while checking if a self referencing FK is null

Sorry. In the process of changing model names to fit my own installation

Re: [bump] Preventing JOIN while checking if a self referencing FK is null

[Andre Terra]

Because django offers a nice ORM that makes it easy to do most queries,
especially one-liners like this one.

And refactoring raw SQL is a royal PITA.

Re: Problem with Django starting up

[Andre Terra]

What I recommend is that you install pip and virtualenv, create a folder
(say, C:\virtual\) where you will place different python "environments" per
virtualenv, then create a folder (say, C:\projects) where you will create
different django projects.

This way you can always use virtualenv to "activate" different environments
and not need to install libraries system-wide.


Basically (blue commands are to be typed in the command prompt):
01. Go to http://pypi.python.org/pypi/pip#downloads
02. Download the archive, extract the contents to a given folder (you might
need 7-zip[1]).
03. Open the command prompt (Winkey+R, type in "cmd" with no quotes)
04. cd into the folder created by the extracted archive in step 02
05. python setup.py install
06. Make sure you have C:\Python27\Scripts in your PATH.
06.1. Do this by typing set PATH=C:\Python27\Scripts;%PATH% in the command
prompt
07. pip install virtualenv
08. mkdir c:\virtual && mkdir c:\projects
09. cd c:\virtual
10. virtualenv --no-site-packages myfirstenvironment (you can name this
after your project if you want to)
11. cd myfirstenvironment

*12. Activate your environment:
C:\virtual\myfirstenvironment\Scripts\activate.bat*

If you want the development version of Django:
13.A. pip install git+https://github.com/django/django.git#egg=django

If you want a stable release:
13.B. pip install django

14. Whenever you need to install a package, just do the same as in step #12
but type the package name instead of django. Don't forget to activate your
environment whenever you open a command prompt window and BEFORE you start
working on your project!


I think that about sums it up. Using this on linux is of course easier. I
hope I didn't miss any steps, but I'm sure others will correct me if I
forgot anything.

AT

This is so not what Django was built to do...

I have a feeling that if you ever do manage to write it, it's going to be
slower than slow and error prone...

Re: Problems getting started

Again, don't install as root, use virtualenv. This will save you headaches
in the future, and unless you have an inexcusable reason to have Django run
as root, you shouldn't.

Using django and virtualenv on Mac OS X. (WAS: Getting Started with Mac OS X)

[Andre Terra]

You should use pip and virtualenv to create a sane development environment.

This guide [1] is originally aimed at ubuntu/linux, but I think you can
probably follow in mac os x as well. I've also listed a few other links
with instructions that look alright, but that I haven't tested.

Basically, don't "ln -s". Use virtualenv instead.

Quote from one of the links:

*"On my systems, virtualenv, virtualenvwrapper, and Mercurial are the only
Python packages that are always available — every other package is confined
to its virtual environment."*

While you might prefer something other than mercurial, the point still
stands. Add only the bare minimum to the system-wide install and everything
else to virtualenvs instead.

AT

Re: best resources for learning django

[Andre Terra]

First of all, welcome to Django!

If you're not familiar with python (and specially managing python
packages), I recommend you setup a sane development environment. Namely
using virtualenv and pip, and optionally mkvirtualenv (if you're not on
windows).

Having to figure out import errors is usually very a frustrating obstacle,
especially for newbies.

Re: Models inheritance in django: how to change PK "_ptr_id" on "id"?

[Andre Terra]

I just read your e-mail quick and somewhat carelessly, so forgive me if I'm
missing something.


Here's a list of things for you to check:

* Have you defined your Client model with abstract = True in its Meta
options?[1]
* Have you syncdb'd[2]?
* If you must name your pk something else, just follow the docs[3]

[1] http://django.me/abstract-base-classes
[2] http://django.me/syncdb
[3] http://django.me/automatic-primary-key-fields

Re: Missing something obvious? Question about forms

In this case, I think he can subclass it and override the validate
method[0] and simply allow any choice to pass, right?

Re: url name to generic class-based views with parameters?

[Andre Terra]

https://docs.djangoproject.com/en/dev/ref/templates/builtins/?from=olddocs#url

# template.html
{% load url from future %}

{% url videos pk=video.pk %}


# 

While we're at it, consider defining a more verbose name to the url, such
as 'video-detail'. I personally like to map url names to an
'app-model-view' syntax, so you can do something like 'myapp-video-detail'
and rename your 'VideoView' to 'VideoDetail'. Then later have
'myapp-video-list' routing to VideoList and so forth. This is also
consistent with the generic class based views offered by Django and helps
keeping your urls.py organized.

The DRY principle applies to writing code, not executing it. Besides, if
different people aren't running the same command once, no one's repeating
themselves.

There are numerous advantages to installing everything manually. When
you're dealing with multiple projects on the same machine, it's the only
way to keep things sane, especially with the advent of virtualenv[1].
Binary python packages will give you an option of which Python install you
are going to use that library for, at the most. They are not made to work
with virtualenv, which I'm willing to bet is running in at least 2/3 of the
stacks running Django in the wild.

If I haven't made myself clear, I'll try again: virtual environments are a
must and they don't mix well with binary packages. Even on windows, you
should 'python setup.py install' from a virtualenv or, even better, use
pip[2].

Re: Does anyone know any blogs that write about how to quickly install and deploy a django application on Amazon EC2?

[Andre Terra]

nginx runs on windows xp, and should run on vista/7 too.

I've even managed to compile a version on cygwin with an additionally
patched module that allows for file upload progress tracking.

If anyone wants it, i can put it on github with a sample .conf file, but no
strings attached at all.

Re: How to avoid "no such column" error when I add a new property to a model?

[Andre Terra]

Or use a GUI tool like PgAdmin[0] for PostgreSQL, which is packaged into
most psql distributions.
