Re: Do you combine you Django decorators?

[Sam Walters]

Hi Andy

I dont combine them... however:
I was using a couple of decorators for almost every view in one
project. Ended up putting them in middleware.
Are these decorators for every view? Maybe you should consider middleware too.

Johnny Cache on Django 1.3

[Charlie Offenbacher]

Hi everyone!

I'm try to install johnny-cache on Django 1.3. I literally followed
the instructions here (http://packages.python.org/johnny-cache/#)
exactly, using the memcached version.

Evverything runs okay, but nothing gets cached at all when I telnet to
memcached. When I used cache-machine, that worked fine, so I know my
memcached installation works.

Any suggestions on how to debug this problem?

Thanks for your time!!

Hi, why not using the embedded uWSGI config parser ?

You can put all the uWSGI option in a ini file with your custom
options:

[uwsgi]
; uwsgi related options
socket = :3031
module = django.core.handlers.wsgi:WSGIHandler()
master = 1
; and here your custom options
my_funny_option = pluto
foo = bar


The in your code you can access all the options with the uwsgi.opt
dictionary:

import uwsgi

uwsgi.opt['socket']
uwsgi.opt['my_funny_option']

django-admin.py startproject mysite

[Santiago Caracol]

Hello,

the Django (1.3) tutorial says:

>From the command line, cd into a directory where you’d like to store
your code, then run the command django-admin.py startproject mysite.
This will create a mysite directory in your current directory.

When I run

django-admin.py startproject mysite,

I get this error:

Unknown command: 'startproject'
Type 'django-admin.py help' for usage.


Using django-admin.py help, I get these subcommands:

Available subcommands:
  changepassword
  cleanup
  collectstatic
  compilemessages
  createcachetable
  createsuperuser
  dbshell
  diffsettings
  dumpdata
  findstatic
  flush
  inspectdb
  loaddata
  makemessages
  reset
  runfcgi
  runserver
  shell
  sql
  sqlall
  sqlclear
  sqlcustom
  sqlflush
  sqlindexes
  sqlinitialdata
  sqlreset
  sqlsequencereset
  startapp
  syncdb
  test
  testserver
  validate

Does the Django tutorial still match reality?

Santiago

If you read the docs (http://packages.python.org/johnny-cache/) on
pypi  there is a reference to the incompatibility and the cause of the
problem.

Re: django-admin.py startproject mysite

[Jiten Singh]

Hi Santiago,

I think there is some problem in your installation of Django 1.3 , i
installed it myself and there is no problem with

*django-admin.py startproject mysite*

even the help of django-admin-py lists startproject command

I think  re-installation can work.

model refuses to save when manytomany field is blank

Re: admin cannot edit records with 'add' as primary key

[Marwan Al-Sabbagh]

Exactly, I think an assumption was made in the original design of the
URLs about the values of the primary keys, maybe that they would be
numeric. So this case brakes that assumption.

Re: Authentication system

[Shawn Milochik]

Do the check in middleware instead of using the login_required
decorator everywhere.

There are snippets on DjangoSnippets for it. They vary slightly in
design, so check them out and pick the one that's best for your
situation.

Briefly, your middleware will check if request.user either
is_authenticated or is_anonymous, then issue a redirect for those not
logged in.

Advice: project hosting apps

[Peter Herndon]

Hi all,

I'm tasked to build an internal project hosting site similar to Github
or Bitbucket for my employer, and I'm wondering what the current
state-of-the-art is for this. I want to provide per-project issue
tracking, wiki or other documentation building, and a nice view of
each project's git repository.

Please let me know of any recommendations you may have for apps that
supply this sort of functionality. I greatly appreciate any
suggestions you may have.

Thanks,

---Peter Herndon

Python Decorators

[cootetom]

Hi all, not exactly a django question but here goes... I'm trying to
implement a decorator with one positional argument and one keyword
argument. My wrapper function gets the positional argument just fine
but the keyword argument throws an error "NameError: name 'as_string'
is not defined."

Code is;

def widget(widget_switch, as_string=False):
def decorator(func):
def wrapper(*args, **kwargs):
# logic in here can access the value of 'widget_switch'
but 'as_string' is not defined?
return func(*args, **kwargs)
return wrapper
return decorator

So if I decorate a view function with "@widget('some_widget',
as_string=True)" then the wrapper function is unable to use
'as_string'. I thought this was how python closer worked?

Any ideas?

Re: Advice: project hosting apps

[Kristaps Kūlis]

Hi,
  Redmine(Ruby on Rails) and Trac(Python) are two most popular alternatives.
  Redmine is far easier to setup for multiple projects.
  Both support Wiki / issue tracking and git :)

  Btw, Code.Djangoproject.com uses Trac.

Re: Odd problem with queryset

[Dmitry Kharlamov]

Try to instead limit the QuerySet:

try:
post = Post.objects.filter(thread = self.pk).order_by('created')[:
1].get()
except DoesNotExist:
post = NULL

return post # or do something else

RE: Documentation Checked But Unclear: How to supress form.errors from views when needed?

[Henry Versemann]

Yes. First thanks for the response. I'm doing some experimenting with the forms 
and well as the requests and possibly reusing them as much as possible, and one 
thing I thought I'd try was to reuse values from a previous screen  which some 
of the same fields names and types, so that when the new screen comes up as 
much data as possible has already been formatted on the screen and therefore 
requires fewer user keystrokes.  The actual issue I seem to be having is when I 
display the new screen for the first time, but with the previously POSTed 
information it seems to want to display errors, which I can understand, because 
since it thinks it's not the first time in that it should display errors, when 
there is no data in one or more of the required fields on the screen. I think I 
have it figured out how to get around this unless there are some pitfalls, in 
doing this a little differently, which I'm unaware of. Thanks again.

I dont understand so you render a view with a form once and you get
form errors on the initial view?

Or

Is there a POST/GET with formdata being submitted generating this
issue? *which would be by design as fas as i can tell you want form
verification to work

Note:
http://docs.djangoproject.com/en/1.3/topics/forms/

If you are binding data to a form for a view and rendering it im
pretty sure you will see form errors if you leave fields blank etc.

Re: Authentication system

[Bryan]

http://docs.djangoproject.com/en/1.3/topics/auth/#limiting-access-to-logged-in-users

You can either put the @log_required decorator on each of the views
you want protected, or you can do it the raw way (see link), which may
offer more flexibility.

Re: Do you combine you Django decorators?

Thanks man this is even better. I have though about doing something

Need Help Understanding How To Use Built-In Authentication

[hank23]

I'm trying to understand the authentication built-in to django and
have some questions. Since the built-in authentication seems to
provide many if not all of the forms and views needed, then do I need
to code anything but calls to those views, from my own views, which
will pass the various bits of information needed by them? if this is
so then do I even need to worry about coding login.html, or the
base.html, which are referenced in the documentation, to be able to
use the built-in authentication? Thanks for the help.

If you really did test on the very same data set, same forum, *same
thread* (IOW ; same value for "self.pk") etc, you would'nt get an
IndexError, so there's obviously something different.

This returns all posts, whatever thread they belongs to.

It's not "causing it to return an empty queryset", it's raising an
index error because your queryset is already empty.

try:
Post.objects.filter(thread = self.pk).order_by('created')[0]
except IndexError:
   # just so you know your queryset is really empty
   # comment this out (or even better remove it) once you made sure
   # the error was in your test, not in Django
   if Post.objects.filter(thread = self.pk).count():
   raise AssertionError("Something has gone terribly wrong")

I was literally just adding the [0] and refreshing the page, doing nothing 
else differently. With the [0], it errors. Without the [0], I get a list 
with two items.  The reason I posted this in here was for the very reason 
that I was getting an IndexError on a set that almost certainly shouldn't be 
empty.

I also worked out that the set wasn't empty by accessing the first item from 
the template instead (i.e. adding '.0' to the end of the value in the 
template tag, instead of [0] to the end of the return function in the 
model).

I know, I was trying to point out that the change in behaviour when I add 
the [0] is most likely due to the filter command.

If you know of a better way I can test it, I'd appreciate it, it will come 
in useful if something like this happens again.

I've since gone another route to avoid having to use the function (this was 
bugging the hell out of me), but thanks for your help + suggestion.

select_related() changes type of DecimalField?

[Carsten Fuchs]

Dear Django list,

using Django 1.3 with Python 2.6.5 on Ubuntu 10.04 and mod_wsgi, with 
Oracle database, I've just experienced a case where the use of 
select_related() changes the result type of a DecimalField in a related 
object from decimal.Decimal to float (which in turn breaks my application).



In detail, please consider the following models (unrelated fields 
omitted for clarity):



class Code(models.Model):
id= models.BigIntegerField(primary_key=True)
grenzwert = models.DecimalField(null=True, max_digits=5, 
decimal_places=2, blank=True)


class Erfasst(models.Model):
id   = models.AutoField(primary_key=True)
code = models.ForeignKey(Code, db_column='code')


And the following shell session:

lori@keep-surfing:~/Zeiterfassung$ python manage.py shell
Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from Zeiterfassung.Lori.models import *

>>> z = Erfasst.objects.get(id=2726498)
>>> z.code.grenzwert
Decimal('10.00')
>>> type(z.code.grenzwert)

>>> z.code.grenzwert > Decimal(0)
True

>>> z = Erfasst.objects.select_related().get(id=2726498)
>>> z.code.grenzwert
10.0
>>> type(z.code.grenzwert)

>>> z.code.grenzwert > Decimal(0)
False


(The last line is the one that caused/causes the problems in my app...)

In the second part of the example with select_related(), I'd have 
expected that it returns type decimal.Decimal as in the first.


Is this a bug in Django?
If not, is there a better solution to the problem than using 
isinstance() in every place where I have to compare DecimalField values? 
(I'm still quite new to Python, and might be overlooking something 
obvious...)


Python 2.7 seems to handle Decimal-float comparisons differently/better 
than 2.6, and the above would probably silently work with Python 2.7, 
but I currently cannot upgrade to Python 2.7.


I'd be very grateful for your advice.

Best regards,

Re: multilingual django

[Andre Terra]

You'll need to run something like

./manage.py makemessages -l pt_BR


This would be the command for generating Brazilian Portuguese language
files. -l is the same as --locale=pt_BR.

Please refer to the docs for some specifics. These two sections should be
the most relevant for you right now:
http://docs.djangoproject.com/en/dev/ref/django-admin/#makemessages
http://docs.djangoproject.com/en/dev/ref/django-admin/#common-options

You'll also find a bunch of examples there. Let us know if you have any
other questions.


Cheers,
André Terra (airstrike)

Form displays as textarea on local server, but text input on remote server

[kelp]

Hello,
I have a form set up in the following way:
from django.db import models
from django import forms

class ContactForm(forms.Form):
subject = forms.CharField(max_length=100)
message = forms.CharField(widget=forms.Textarea)
sender = forms.EmailField()
cc_myself = forms.BooleanField(required=False)

On my local machine, the "message" actually displays as a textarea,
but on my remote server, the "message" displays as a text input. I am
using Django version 1.2.3 on my local server and 1.2.5 on my remote
server. Yes, I am sure that this file is identical on both servers.

I am displaying the field with a simple: {{ form.message }}

Why does it display differently?

Thanks!

[Template Filter] How to get rid of the extra 0 after the decimal point?

[David.D]

I hope to get this result:
34.000 --> 34
34.100 --> 34.1
34.120 -->  34.12
34.123 -->  34.123

But the output of floatformat filter is like this:
34.000|floatformat:"-3" --> 34
34.100|floatformat:"-3" --> 34.100
34.120|floatformat:"-3" --> 34.120
34.123|floatformat:"-3" --> 34.123

Thank you very much.

Re: Advice: project hosting apps

[spawgi]

We use an internal implementation of Trac in our org. I think Trac has a
good potential if used properly.
However the Trac workflows are directed mostly towards development tasks and
not QA tasks.

Redmine also has good features from what I have read. But I have never used
it.

Here is a comparison of project hosting and tracking tools.

[django-ratings]Problem if my id key is not an integer.

[David.D]

My models all extend my custom model class which id is a CharField not
a PositiveIntegerField like the Django's default
django.db.models.Model .

So, when I try to add a vote, I got a ValueError:
invalid literal for int() with base 10: 'my-char-id'

Because the object_id field is defined like this in django-
ratings.models:

object_id   = models.PositiveIntegerField()

Any ideas how should I deal with this ?

Thanks in advance.

Re: Johnny Cache on Django 1.3

transactions, which we're not using.

Yes, this appears to be a bug.  If you would, please create a ticket
for it in the Django Trac so that we don't forget about it.

jQuery namespace woes - calling third-party scripts

[Andre Terra]

Hello.

I'm trying to run the supersleight jQuery plugin (
http://allinthehead.com/retro/338/supersleight-jquery-plugin) for fixing PNG
transparency in IE6 (this is a corporate intranet project, so I must support
it).

However, I'm having trouble calling the script because it's telling me
jQuery is undefined. Could somebody please paste me an example of how I
should setup my project's main script (and references to both that and the
third-party files) so that either jQuery or $ will work anywhere they're
used?



TLDR; I just to call this 'supersleight' plugin on document ready:

django.jQuery('body').supersleight();

I know, it's incredibly simple, but I can't get it to work.


I thank you in advance for the help.


Sincerely,
André Terra (airstrike)

Re: Johnny Cache on Django 1.3

[Charlie Offenbacher]

Alright, this was my bad! It was a silly configuration error. Just in
case anyone else runs across this, I was using the pattern for local
settings files where you do...

try:
from local_settings import *
else:
pass

... doesn't work so well if you have a syntax error in local_settings,
and it's hard to notice! Live and learn.

Thanks everyone, vanilla Johnny-Cache is working for me on 1.3 now!

Static/media url in template

[Jon J]

Maybe I'm missing something...

I would say I'm relatively familiar with the Django framework by this
point. I'm mocking up a website, and I want to link static files into
the base template. Instead of having the url's directly in the
template, I'd like to call the STATIC_URL variable from within the
template, so for example I could have



instead of

http://www.domain.org/style.css"; />

Is this something that's possible or advisable? How is this problem
normally handled so I don't have to retype pretty much everything if I
move my site around? I haven't been able to find anything in the
documentation regarding this.

Re: using a models fields

[bishwendu kundu]

You can try saving the data as
latitude=models.DecimalField(max_digits=7,decimal_places=4).Same for the
longitude field.Here the max_digits takes into account both decimal and
non-decimal places.All the data can be given in string form as it will be
automatically converted to proper format as specified in your models for
storing in database. I guess you will be using some criteria to extract data
from the database...so,code can look like

list_of_XYZ()=XYZ.objects.filter(criteria)
for i in list_of_XYZ:
i.latitude,i.longitude ,i.zoomlevel

Re: Static/media url in template

[Sam Walters]

Yes it already exists {{MEDIA_URL}}

Thats what the settings.py file does...

There is a bunch of stuff you can read about in the docs:

http://docs.djangoproject.com/en/1.3/howto/static-files/

Also for some of my own deployments there are a bunch of static file
servers so i just put these into settings:
{{MEDIA_URL_VIDEO}}
{{MEDIA_URL_IMAGES}}
etc...

Basically its as extensible as you want to make it.

cheers

all you need to do is copy all the templates to a directory called
'registration' under your templates directory and do whatever style
modifications you want. The views will work automatically.

installer

[ydjango]

Is there a package or easy way to create an installer to auto install
apache, django, mysql based web app?

There could be some manual steps like installing mysql and providing
setup screens to enter connection data to mysql and mail server.
I would want to at minimum, when installer is run by user, auto
install all the many python packages, install django and build my app,
and delete py files automatically.

Using the same block in a django template to display different information depending on a variable

[Ethan Yandow]

Hey Mr. Django! I am trying to have different information display in
the same block depending on a variable "choice" which is simply an
int. The way I was planning on doing so was going to be something like
the bellow code:

{% extends "index.html"%} {%block head%}

Welcome to Piss && ink {{user}}

{%endblock head%}
{%block one%}
The temperature in {{city}} is {{temperature}}°

{%endblock one%} {%if choice1 == 2 %} {%block two%}
The temperature in {{city}} is {{temperature}}°

{%endblock two%} {% endif %} {%comment%}{%if choice1 == 2 %} {%block
two%}
The temperature in {{city}} is {{temperature}}°

{%endblock%} {% endif %}{%endcomment%} {%block two%} {%csrf_token%} {%
if new_event %}
{{new_event}}

{% endif %} {%endblock%}
Now, the problem I am having is that the template doesn't like that
there are two blocks of the same name in the template. For some reason
it doesn't seem to care about the {%if%} statement that is checking
where the {%block%} is supposed to go. I thought that the {%if%}
statement would only execute what was inside itself depending on its
parameters but it doesn't seem to be doing that. It displays
everything inside the {%if%} no matter what "choice1" is equal too :
( Does anyone have any idea how I might be able to fix this? Thanks

By way of clarification -- there's a reason that you need to take this approach.

{% block %} tags are the one and only example of precedence rules in
Django's template language. Blocks are evaluated before every other
tag, because they involve the gross structure of the template itself.
You can't have a "conditional block", because the conditional tags
aren't evaluated until after the block is evaluated.

Re: Using the same block in a django template to display different information depending on a variable

[Sam Walters]

Hey

Block tags dont work like that.

{%if choice1 == 2 %}

{% include "sometemplate.html" %}

{%endif%}

instead of:

 {%if choice1 == 2 %} {%block two%}
> The temperature in {{city}} is {{temperature}}°
>
> {%endblock two%} {% endif %}


I hope that was what you were thinking...
http://docs.djangoproject.com/en/1.3/topics/forms/

There is an example in the form docs.

The best way is to script the installation. Google for "scripted 
installs " or similar. You should find some examples you can 
rework to suit your needs.


I think this is a very healthy way to install stuff just in case you 
need to repeat the process on another machine. The scripts leave a nice 
record of what you have installed.



There could be some manual steps like installing mysql and providing
setup screens to enter connection data to mysql and mail server.
I would want to at minimum, when installer is run by user, auto
install all the many python packages, install django and build my app,
and delete py files automatically.

For Python applications you can also script installation. I usually call 
the Python script at the end of the os instyallation script. I use pip 
and here is an example. I uncomment lines as required and comment them 
out again after a successful install so I don't accidentally re-install. 
You need to study the documentation for pip if you decide to use it ...


#
# requires 1. setuptools and 2. pip
#
#pip install django
#pip install markdown
#pip install psycopg2
#pip install south
#pip install django-tagging
#pip install django-cms
# having trouble with buildbot/twisted - debug via /usr/local/lib64
#pip install buildbot
#pip install akismet

i18n and l10n of third party applications/libraries

[poswald]

I've got a situation similar to this one:

http://stackoverflow.com/questions/3933824/djangos-i18n-with-third-party-apps

Basically, I have a pip-installed third party library with strings
marked for localization but with no localizations provided. In my
project I would like to provide translations to be used for the
strings in this library. Is there a way to get 'manage.py
makemessages' to scan a third party library and create a po file for
it? Once that is done, where would the .mo file go such that it is
applied to the library objects when they call ugettext_lazy?

Thanks,
-Paul

Eclipse mylyn can be integrated with Redmine too.
We are using Redmine with some plugins for time sheduling, SCRUM support

Extending django-admin.py startproject/manage.py startapp: a good layout for reusable apps

[MrMuffin]

I`m writing a simple extension of django-admin.py/manage.py so I can
have a predefined set of configurations and use those when I create a
new project or reusable app. For instance, I use sqlite3 in the
initial stage of development so that should be set automatically. My
name doesn`t change that often, same for me email. Those things should
go into the settings.py by default. And when I create reusable apps I
don`t want to bother with setting hardcoded links in settings.py to my
template-folder in settings.py either.

So what I`m thinking of is an extension of manage.py, let`s call it
"lime" for now, an executable script, working something like this:

1. All my default values; name, email, django settings that doesn`t
change much are stored in a config file in my home directory like
~/.lime/config.ini
2. When I call "lime app blog" the result is:

* a folder with a package called blog, a complete reusable django app
( I use the standard django code to generate the app itself )
* a setup.py with my name, email, package info, basics requirements -
all ready for pypi uploading and distribution
* a test-project to test my reusable app, configured to use that app
and find the templates and static content automatically without adding
hardcoded paths to the settings.py of the test-project and an admin
inteface enabled by default
* a virtualenv for my test-project
* code revision files for files to ignore etc
* 

The goal is to quickly create a standardized, complete and distribute-
friendly layout for a reusable app and to cut down on the manual,
repetetive typing. I`m also planning to support different configs so
calling something like "lime app blog --config postgresql" will use a
config specifying the app to use a config called postgresql instead of
the default.

So what are your thoughts? And what is a good layout for a reusable
app? What else could be automated in django development?

My main motivation for this project came when I started working on a
plugin for the Editra editor for django management. I wanted to create
django reusable apps from inside the editor and I saw that a lot of
the initial work on a new app is very repetetive - first create
project, then create app, then edit settings.py, then urls.py to
enable admin, then edit views.py to enable admin etc. I want to have a
configurable standard layout for my apps created in very few steps,
from within Editra and outside the editor as well.

Thanks for your attention and hope to hear some of your ideas or
thoughts.

Regards,
Thomas
