Displaying template location in html

[Alec Taylor]

With 40+ HTML files it's easy to get confused as to where each
component comes from.

I don't want to annotate each file with its relative path manually, as
this will prove cumbersome when the site finally goes production.

Is there a trick to displaying the template location on-screen?

Thanks for all suggestions,

Alec Taylor

Re: I need help with Python Tools for Visual Studio 2010 and Django

[JJ Zolper]

lawgon,

I have set up VirtualBox with Python and Django. Things have gone 
flawlessly.

Only thing I've noticed is it seems to be running a tad bit slow. I feel 
this way because I had a native installation before and it ran quite well.

Before I go too far into writing code I was hoping to "perfect" my 
environment. I want to be able to donate enough resources such as RAM to 
the VM so that it runs well but at the same time maintain a steady local 
Windows boot.

Would you mind helping get me situated?

My Laptop is a Fujitsu Lifebook T5010. A 231 GB HDD with 4 GB RAM. I have 
Windows 7 Enterprise 64 bit operating system installed.

The original or current setup for my Ubuntu 11.10 on my VirtualBox system 
is:

Base Memory: 700 MB (RAM? max is 4096)
Storage: 40 GB (Fixed)
Video Memory: 12 MB (max is 128)
Monitor count is 1

Those are all the details I thought might be useful. I would really 
appreciate some guidance as to what you set yours up as or what you think 
might be the best to optimize performance?

As a side note I'm really asking anyone in this thread what their opinion 
is? I plan is to look through this thread and see who else mentioned Linux 
and see if I can get input so I'm ready to go before I dive too deep into 
my development.

Thanks to you and to everyone who has been very patient with me, given me 
so many tips, and stepped me through my setup!

Much appreciation,

JJ Zolper

passing context data to inherited templates

[Mike]

In a project I'm working on I have a status bar at the top of the webpage 
that will render data using template tags.  The status bar will be 
displayed on all of my views, so I want to put the html code in my base 
template.  The base template is imported to all of templates using the 
'extends' template tag.  Now the base template needs a dictionary of data. 
My question is, how do I pass this data to the base template?  I'm passing 
it in the context data of every view that renders a template, but it seems 
like there should be a better way - for example the base template calling 
out to a python function that can add data to the context before its 
rendered. Is there any other way to pass data to a base template?

Re: Apps vs Project

[Brian Schott]

This was hard for me when I started with Django about a year ago and I'm still 
learning, but I've found that I prefer to break things down into multiple small 
apps so that the models.py, admin.py, views.py, tests.py, etc. all are fairly 
small and easy to understand within a single app.  The project settings.py can 
then just import them each as you would another external app.  

See my comments in the thread for the layout and a few tricks that I use:
https://groups.google.com/forum/#!topic/django-users/gNvhuTADOiA

Foreign keys work across app boundaries, you just need to have the apps on your 
python path and do:

from django.db import models
from crm_customer.models import Customer

class PurchaseOrder(models.Model):
   customer = models.ForeignKey(Customer)
   ...

Also, setting the app_label, you can make all the little applets appear in the 
same grouping on the admin page and essentially share a namespace for metadata 
like django-guardian permissions.  

class Meta:
app_label = 'crm'

Re: Adding first_name and last_name to django registration

[Andres Reyes]

The django.contrib.auth User model already contains first_name and
last_name fields so you don't need a UserProfile for that.

Also the view that handles the registration takes a form_class that
parameter that you can pass in the urlconf, you would only need to
subclass the RegistrationForm, add your fields and then pass it to
django-registraion

Tutorial for dev version not working (Polls app): admin

[Alec Taylor]

Going through the tutorial using the latest trunk in a virtualenv.

I am getting stuck in this section:
https://docs.djangoproject.com/en/dev/intro/tutorial02/#s-customize-the-admin-form

No matter how I rearrange the fields (even when I remove the
"question" field), I cannot notice any difference in the poll admin
screens. I have tried syncdb, and restarting the server.

I've looked at the index screen
(http://localhost:9400/admin/polls/poll/), the view screen
(http://localhost:9400/admin/polls/poll/1/) and the add screen
(http://localhost:9400/admin/polls/poll/add/). There are no
differences in field order/display on any of these pages.

I have followed the tutorial exactly, but the fields aren't being rearranged.

Is there a different way of rearranging admin fields in Django 1.4?

Thanks for helping me get this working,

Alec Taylor

Re: Adding first_name and last_name to django registration

contrib.auth.models.User has a get_profile() hook that allows you to add

You shouldn't be trying to initiate a script from within a view.

The request-response cycle needs to be short lived. The responsiveness
of the user's experience is directly tied to how long it takes for
your server to complete executing a view; if you're invoking
subprocesses (especially long lived subprocesses) as part of a view,
then you aren't going to b

"Oh, but my subprocess *will* be short lived!" you say? Well, you've
still got a problem -- because your user can hit cancel at any time
during a request, closing a connection, which can cause all sorts of
interesting problems with managing dangling subprocesses.

If you need to execute something long lived, you should break it down
into parts:

 1) A view that creates a "job". This doesn't need to be any more than
writing a single entry in a database table.
 2) A view that can be used to poll the status of the job.
 3) A background task -- completely outside the request-response cycle
-- that executes jobs, and reports the status back to the database
table.

This ensures that the expensive process is handled out of the
request-response cycle, yielding a more responsive interface, and
giving you better scalability, too (since your ability to handle
background processes is decoupled from your ability to handle user
requests for background processes).

There are many ways to achieve the background task -- celery is one
popular option, but you can organise an quick and nasty
proof-of-concept using cron.

Re: Help with new version of django

[Aaron Cannon]

I suspect he means the latest stable version, in which it really is
1.3.1.  To my knowledge 1.4.1 does not yet exist.

As for the original question, I would suggest familiarizing yourself
with the what's new documents for Django 1.2 and 1.3, and then tuning
your code accordingly.  Depending on what your application does, it
may be quite painless.

Alternatively, if you have good test coverage, you might just upgrade
your Django version, test, and fix what's broken.

Obviously, the first option is probably the better, but regardless, it
will be quite difficult for anyone to give you specific advice based
on the amount of information you provided.

Django Deploy - Some Questions regarding it

[Felipe Arruda]

Hi there everyone, I'm trying to make my first deploy of a project,
and encountered some problems.
Here is the scenario:
I read that to make uploaded files only accessible for the
uploader(the user) was a better choice to use nginx(apparently more
easy to configure).
But after following a couple of tutorials(a lot of them actually) I
still couldn't make it serve the media files, but them I got really
confuse, and decided that I should review my concepts before trying
any further.
So here are my questions:

Does Nginx serve the files that the user upload or just de static
ones(css, admin_media and stuff)?
If so:
-- Could anyone give me an example of configuration for this?
-- Should I remove the url conf  that maps '^media/(?P.*)$' ?
If not:
-- Then how should I config my settings in production so that it
serves my css and admin_media?
-- How should Nginx be configured to serve me this?

And also there are other matters, like:
Should I configure django.sites to point to what? or I don't need this
set?
What is better: Copy admin/media to my media folder, or my static
folder? or should I just make a symlink?
And finally should I change the directory permissions to the nginx
user:group? If so, then what directories? Just the media/static, or
the hole project?(I'm leaving the media/static folder inside the
project folder, is this a problem to deploy?)

Thanks for the atention, any help is welcome since I've been for 4
days trying to make this work(in a virtualmachine, testing in lan) and
still no media/static been served(but I could manage the site to run
and appear, but no css in admin).

Re: problems running subprocess inside django view

[Brian Schott]

As the same user? Are you running with manage.py runserver? Generally it is a 
bad idea to call subprocess from a web process context. A blocking call you 
don't expect might time out the client and/or hang your server.  

Check out Django-celery.  Create a tasks.py and have your view call a task.

Django ManyToManyField JSON Fixture

[jondbaker]

Hi - I'm working on my first Django project and am trying to set up
the fixture data for my blog app using JSON. Everything works
correctly until I try to set up 'tags' on a 'post' which is a
ManyToManyField. When I run '>>> python manage.py sqlall blog' and
check out the proposed SQL, the table 'blog_post_tags' is listed and
defined correctly. However, when I try to run '>>>python manage.py
syncdb' I am met with the error: 'DatabaseError: no such table:
blog_post_tags'.

model:
class Tag(models.Model):
title = models.CharField(max_length=30)
date_created = models.DateField(auto_now_add=True)
date_updated = models.DateField(auto_now=True)

class Post(models.Model):
...
tags = models.ManyToManyField(Tag)
...

fixture:
[{
"model": "blog.Post",
"pk": 1,
"fields": {
"title": "Demo Post 1",
"category": 3,
"tags": [1],
"body": "This is a sample body.",
"is_published": "1",
"date_created": "2012-01-28",
"date_updated": "2012-01-28"
}
}]

Starting a new Python blog

[Kevin]

Hello Everyone,

  For sometime now I have been itching to create a Python blog, and
now the fruits of my labor have paid off.  I am ready to release the
blog to the public eyes.  At the moment it has 2 main features, a blog
portion, and a bookmark system.  Both the blog and the bookmark system
offer an RSS Atom feed.  The bookmark system is fully compatible with
"Live Bookmarks" to quickly access some of my top Python sites I visit
or visited recently which caught my eye.

  The website is called "Python Diary", a rather unique take on a tech
blog name.  The site itself has a diary-like theme, and is for the
most part very easily to navigate.  The website was completely built
using Python, the theme was taken from a wordpress theme website and
formatted to work with the Django template system.  The entire backend
is written from scratch using a few reusable Django apps, namely,
django-tagging, south, and cumulus.

  Now you might be saying, "Oh great, yet another Python blog".  But
wait...  I plan on setting this blog apart from the thousands of other
blogs in the world with some very unique features.  Features normally
found on commercial software blogs, movie and video game blogs is a
thorough review system.  I plan on going through many of the available
Python packages out there in the wild and basically reviewing them
like one would review anything else.  I do not see a dedicated Python
website which has reviews of many Python packages available in PyPi.
I plan on stating the usual pros and cons of the package, and
providing a score.  For example of how this type of review is
formatted, take a look at a CNET Review.

My new blog can be found here: http://www.pythondiary.com/

  Tell me what you think of the website in general, and the overall
idea for this blog.

If you would like to subscribe to the upcoming content, add this RSS
feed to your favorite RSS reader:

Django - filters

[Sandeep kaur]

Hello all,
In my django application, all the data of different clients are
entered. Sometimes data of even same client is also entered. Now what
I require is to get all the data of the client when it asked for.
The views I used is:

  def old_client(request):
   if request.method == 'POST':
   form = OldClientadd(request.POST)
   if form.is_valid():
   from TCC11_12.automation.functions import *
   cd = form.cleaned_data
   name_and_address = cd['name_and_address']

   title = get_object_or_404(Variable, pk='1')
   sign = get_object_or_404(Variable, pk='3')
   from TCC11_12.automation.choices import *
   client =
ClientJob.objects.filter(name_and_address=name_and_address)
   amount = Amount.objects.all()
   suspence = Suspence.objects.all()
   total_temp = Amount.objects.aggregate(Sum("total"))
   total  = int(total_temp['total_sum'])
   net_total_temp =
Amount.objects.aggregate(Sum('net_total'))
   net_total= int(net_total_temp['net_total__sum'])
   template ={'form':form,
'total':total,'title':title ,'sign':sign, 'net_total':net_total,
'client':client,'amount':amount,'suspence':suspence,'name_and_address':name_and_address
,}
   return
render_to_response('automation/oldclient.html',locals(),
context_instance=RequestContext(request))
   else:
   form = OldClientadd()
   return render_to_response('automation/client.html', {'form': form},
context_instance=RequestContext(request))

Here I get filtered the data of the client I require, from amount and
client  table. But when I go for the sum, it add all the data in
amount field without providing any filter.

Is there any way to find aggregate sum of only those amounts that are
previously filtered ?
I cannot give filter on amount as name and address field is not there
in Amounts table.

Hierarchical Django Ajax Forms

[D X]

I needed to build a form where the user can input a geographical
location, with fields for country, state, city, neighborhood.  I
wanted the form to use AJAX, so that the only valid fields would
appear as the user selected fields higher in the hierarchy.

It sounded like a task that should be easy to automate, but I didn't
find anything that quite did it online.  A lot of examples on how to
do it, that involved writing a bunch of handlers manually.

Here's my attempt, it makes it pretty easy to apply to any set of
hierarchical data.  So if you want to apply this to a set of models
for (Model Year, model, make, trim), or (kingdom, phylum, class,
order, family, genus, species), it should be pretty simple.  The steps
to create the form would be:

1. Define a model representing your form.  The model should contain
foreign keys to models in your hierarchical data set.  However,
instead of using the django ForeignKey field, use
hierform.fields.HierarchicalForeignKey.

2. Defined a form that uses your model, but inherit from
hierform.fields.hierarchicalForm instead the django ModelForm.

3. Add a view to handle all the form requests.  This view needs three
sections.
i. You need to handle POST request to handle form submission.
This is the same as normal Django form submission.
ii. For generating the form, instead of just using the form class
to create the form, use a utility function from this package
ajaxRequest(request.GET).  In the usual case, request.GET is empty and
this call instantiates a normal unbound instance of the form that you
can render into a template to display.
iii. If request.GET contains AJAX form submission fields from your
hierarchical data set, ajaxRequest(request.GET) will generate a small
HTML snippet that contains only the updated select fields.  In this
case, you want to deliver this snippet straight back to the web page,
without the rest of your HTML template.

4. Add a view to deliver the Javascript to your form.  Really all this
does is inject the html tag location of your form, and the URL of your
form into a template containing the javascript.

Source for a demo, and a more descriptive readme are here:
https://github.com/dragonx/django-hier-ajax-form

I'm pretty new to python/django.  If any experienced developer has
time to take a look I'd love some feedback, especially if I'm using
any poor coding practices for Django.

This is also my first time contributing anything open source.  If
there's a better way to make this available, or if you use it and want
to contribute an improvement, or want to set up a live demo for me,
please let me know.

Adding first_name and last_name to django registration

[Zach]

I am new to Django and have implemented the django-registration app on
my website. I want users to input their first name and last name on
the registration page. However, the default setting only ask users for
their email address/username/password . Is there an easy way to
address this?

None of these libraries is very good at parsing "real-world" (broken) HTML 
though, for that you'd better go with html5lib, lxml.html or BeautifulSoup (in

Re: problems running subprocess inside django view

[Eugene Gavrish]

You are not alone with this problem. But I haven't got any decision.
Maybe its django-specific with Popen??

I divided my task in two part: first cron-driven disk file generation.
Second - from django-view this file parsing.
It satisfied my goals, but question with Popen is still opened...

Re: Django vs. Ruby on Rails

[sigep311]

> 3) Using one or the other for Geographic Information Systems work;

I work at NASA/JPL and have been using Python for 1 year, and have
been working in GIS for 3 years.  GIS is built around 2 core
languages, Java for back-end servers and largely due to the amazing
GDAL library.  The other dominate language is Python.  I was working
with the USGS on a project and every time something needed to be done
outside the typical WMS, WCS or ESRI Arc(whatever) it was done with
Python.

Can't add much about the other items, but if GIS is a core decision
point know that Python is heavily favored over Ruby.

Good Luck,

Cameron

I've used both Django and Rails extensively the past 5 or 6 years.
For me it depends more on the project for which one I choose.  If it's
a really important project that I envision working on long term I go
with Django.  But if it's just a simple or fun project I might go with
Rails.

The Rails community loves change.  There's no shortage of forked
(incompatible) gems lying around.  Instead of contributing changes and
improvements back to the original project, developers often fork and
ship their own custom version of a gem.  I once found 5 different
forks of Rcov while setting up a new Rails project.  The original
version of Rcov wasn't compatible with what was the new Ruby 1.9 at
the time.. so everyone had an Rcov fork with their own take on the
required fixes.  Gem dependencies are sometimes very frustrating with
Rails.  I've never ran into such things using Django and Python.

Another thing that erks me to no end about Rails is they assume you
are using sudo.  The new bundler gem is a total pain to deal with if
you are on something like Debian where sudo isn't installed by
default.  I hate sudo.  It's like permission to be irresponsible with
root or something.. pretty lame.

One thing I love about Rails is the speed of development.  It does a
lot for you.  Lots of generators to whip up quick code when required.
But that speed comes with the cost of introspection later.  Rails
doesn't know anything about your tables until it looks.  Even if you
go to all the trouble of writing database migrations, it doesn't even
use them later, choosing introspection instead.  Some will say you
don't have to specify model fields in Rails like you do with Django,
but that's exactly what a Rails migration is.. so you do do that on
most non-toy projects.


> 1) Comparing the framework to Django;

You can accomplish the same things with either.

Everyone seems about the same to me, but you should Google Zed Shaw's
rant about leaving the Rails community.  It's pretty funny.

I have not used Python 3 yet, but I can tell you, the latest Ruby 1.9
series is slower than the old 1.8 series.  Last summer I built the
same app twice using Django and Rails.  Apache bench showed the Django
app to be significantly faster.  Python seems a bit faster than Ruby
in general.

The strengths and weaknesses and features are all fairly well known at
this point, so not much to discuss I imagine.

Rails seems risky to me.  Django feels like a sure bet.  Maybe I'm
just old, but sometimes I get the feeling Rails is being built by some
kids in someone's basement.

Re: User-specific sites

[Mario Gudelj]

It's all in queries. You assign the user to all your tables as a foreign
key and make sure that all your quiries have user in them as a filter. You
can also extend the user and assign a slug to it so that you have unique
urls for all users. You can generate a slug from the username upon user
creation. That's really it. Cheers

Re: I need help with Python Tools for Visual Studio 2010 and Django

[Jonathan Paugh]

Developing on a Linux-based OS will give you indispensable understanding
of your production environment. On the other hand, it will probably be
very unfamiliar if you haven't worked on Linux before, and easy tasks
will become very difficult again, for a while. You should ultimately
develop your application on the platform that makes you the most
productive---the portability of Python and Django gives you that
luxury---you could even target the Java Virtual Machine. (And you won't
know that without trying them all.)

Definitely try out running a development websever './manage.py runserver
is fine) on Linux, to get a feel for what your production environment
might be like. You might decide you like working on Linux, and it make
you more productive---or not. But---at least for Django/Python---that's
largely a matter of taste.

Re: How do you pass dissimilar data from view to template?

I think jQuery supports this sort of thing, (as I'm sure other
Javascript libs do). Then again, learning Javascript + jQuery together
seems at least as hard as learning Python + Django.

Re: Handling multiple parameters on URI via GET

[Jonathan Paugh]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Is the request.GET.get() method working properly? Does the test on
query work? I suspect one of these places doesn't work as expected.

I'd do similar to the following in my code. (It works on Django 1.3.1
for request.POST, anyway.)

if 'page' in request.GET:
  # do pagination
elif 'search in request.GET:
  # do search
else:
  # do something else

Re: what is the best IDE to use for Python / Django

[hari jayaram]

I like using Pycharm . The 2.0.1 version has pretty good integration
with bitbucket , github and other VCS/DVCS


I also use emacs and have heard good things about  sublime2
