Django cache view

2010-11-12 Thread Mathieu Leduc-Hamel
Hi all,

I'm working on a e-commerce website and to make it work better we've
implemented a couple of caching strategy. But i was wondering, in our
system, we are using the cache middleware and the decorator to mark
some views as cacheable.

But, loading multiple times the same view, it seems there's some
activities on the database side.

I don't understand why,

The view is very simple and we've just put something like that:

@cache_page(3600)
def category(request, template=...)

What's used there as key in the cache ? What's not working ? I've
already configure the middleware and make sure memcached is working
properly.

What's not working ?

Unicode, utf8, mysql

2010-10-11 Thread Mathieu Leduc-Hamel
Hi all,

I'm the main maintainer of a website called l'Agenda Du libre du
Québec. On this website, people can submit events about free/open
software in their local community.

Yesterday, somebody tried to submit a new event, but the in
description of the event, there was a strange character: "→". Django
can deal with this unicode character, and MySQL, correctly configured,
should be able to also.

But it's not the case. MySQL just refuse to save it ! Saying that
there's an invalid character inside this field.

What can do ? I don't want to filtering it manually and just wait for
the next bug for the next incompatible character with MySQL !

Confoo 2011 Call for Speakers

2010-10-06 Thread Mathieu Leduc-Hamel
Greetings Djangoers,

We, Montréal-Python, are the coordinators of the Python track at
ConFoo 2011 and we are very proud to announce our call for speakers.

PHP-Québec, Montréal-Python, Montreal.rb, W3Qc, and OWASP Montréal are
organizing the first edition of the ConFoo conference, which will be
held in Montréal on March 9th through 11th at the Hilton Bonaventure
Hotel.  With over 500 expected attendees, ConFoo is one of the largest
Web development conference in North America.

ConFoo is about the Web, but it's also about showcasing the strengths
of different technologies.  Do you think that Python beats all the
other languages out there for Web development?  Do you think that
Django knocks Pylon's socks off?  Come and tell us why!

Sessions are one hour long and you can present in French or in
English, which ever your prefer.  Submissions are due for November 26;
for more details, visit the ConFoo website:

  http://confoo.ca/en/call-for-papers

By the way, we are perfectly aware that there is a slight clash with
PyCon.  You should not worry about that since all Python talks will
happen before Friday, giving you plenty of time for the commute
towards Atlanta.

Share the word!

Re: GoFlow - anybody out there used it?

Another option might be http://github.com/knipknap/SpiffWorkflow at
the time where i was searching for a workflow solution for my project
it seems in pretty good shape. Although, the API was not enough
Pythonic and a little too complicated.

I finally didn't need to use a worlkflow solution and choose to use
repoze.workflow which is more a kind of statemachine...

good luck and i would be interested to have your impressions

Re: PIL on 10.6 = PAIN

2010-09-01 Thread Mathieu Leduc-Hamel
This is because you should not use the Python interpreter from you're
Mac installation. Are you using buildout ? VirtualEnv? or nothing ?

Buildout:

/opt/local/bin/python2.6 bootstrap.py

Virtualenv:

virtualenv -p /opt/local/bin/python2.6 

Nothing:

/opt/local/bin/python2.6 manage.py runserver

Re: PIL on 10.6 = PAIN

2010-08-31 Thread Mathieu Leduc-Hamel
To work with PIL and other librairies a little bit weird and difficult
to install the best way is to install Macport and after that:

port install py26-pil

and you'll need to use the python of the macport installation:

$ /opt/local/bin/python2.6

It's the samething on linux, i'm alway using the PIL package from my distro...

Re: how to turn off CSRF in django 1.2?

2010-08-26 Thread Mathieu Leduc-Hamel
If I was you,

I would not install django directly on the system. It's not generally
a good practice.

The best thing you might do is to use of these two methods:

1. virtualenv 
(http://tumblr.intranation.com/post/766290325/python-virtualenv-quickstart-django)

2. buildout (http://jacobian.org/writing/django-apps-with-buildout/)

As you wish these two methods worked pretty well, on my side i like
buildout cause it's easier to maintain.

The process doesn't fallow the same way it does in PHP.

It's complete new world (and a more beautiful and peaceful one i think).

Your connection will be keep alive, don't worry about that. What do you mean
by connection ? The connexion to the database ?

Re: django and php

2010-08-19 Thread Mathieu Leduc-Hamel
Have you took a look at the tutorial on the django webpage ? It's a must to
read before doing anything with django.

After that i can propose to you a solution:

If i was you i would code 2 views

One for the rendering on the page
One as ajax view

The first one would use the javascript to reload something every minutes and
the second would just fetch the data from the database.

Look in the documentation to know how to develop correct ajax views...

Re: How to execute some user defined codes (functions) when Django boot?

2010-08-18 Thread Mathieu Leduc-Hamel
The problem with that way, as said before is that you don't really know if
your code will be executed at startup in the wsgi context... and exactly at
what time.

Re: How to execute some user defined codes (functions) when Django boot?

2010-08-18 Thread Mathieu Leduc-Hamel
Richard,

it's not the good way to do this, in the settings.py cause as i said before,
the code in the settings.py is executed every time somebody initiate a
session for the first time. The point there is a way to have a part of code
common to all currently connected user.

Tang,

I'm not an expert of the middleware development in Django but from what i
saw in the documentation it could be a great way to do that. Look at this
comment by example:

"For performance reasons, middleware classes are only instantiated *once* in
long-running server processes; this means that you can’t count on
__init__ getting
called every time a request runs, only once at server startup.
"
"

- http://www.djangobook.com/en/beta/chapter16/


You'll need to test if it's true but there's a great possibility it would be
the case in real world experimentation.

But if i was you i would really try twod.wsgi cause this guy is using
something that have bean used from time to time in the Pylons world where
this kind of use case is perfectly solvable.

Re: How to execute some user defined codes (functions) when Django boot?

2010-08-17 Thread Mathieu Leduc-Hamel
Paul, no it's not exactly the point. When you said some code on the boot up
it means really a piece of code shared by everyone and executed just one
time, by example, for mod_wsgi it would be when apache is starting.

That's exactly what's done in the Pylons world to be able to load some piece
of code like the different middleware initialization. It could be useful
when you need launch some external long running process or anything like
that.

But putting the code anywhere cause it would be evaluated when the code is
loaded is not safe cause you don't if everything was correctly loaded a this
time...

Re: Chopping Queryset

If you want the job offer of the current logged user it should be pretty
simple using a filter like that:

jobsfound.filter(userdetail__user=request.user)

But if i was you i would invert the order of these two filter like that:

jobsfound = joblist.objects.filter(userdetail__user=request.user)
jobsfound = jobsfound.filter(name__icontains=cd['jobsearchitem'])

Proxy models and Meta options

2010-08-17 Thread Mathieu Leduc-Hamel
Hi all,

I've just used a proxy model in my own custom application and i've just
found a small problem. Right now, to be able to create a Proxy model, i'm
force to redefine a Meta options like that:

class NewDiscount(Discount):
class Meta:
proxy = True

The problem i have is that the original discount object defined the
following Meta options:

class Discount(models.Model):
class Meta:
verbose_name = _("Discount")
verbose_name_plural = _("Discounts")
unique_together = ('slug', 'amount')

Since i've overwritten the Meta class I should copy the original Meta
options inside my Proxy model like that:

class NewDiscount(Discount):
class Meta:
proxy = True
verbose_name = _("Discount")
verbose_name_plural = _("Discounts")
unique_together = ('slug', 'amount')

But, when I'm doing that, Django throw me an error saying:

"store.discount: "unique_together" refers to site. This is not in the same
model as the unique_together statement."

It means that i can't add the unique_together clause in the Meta class cause
the fields are not directly the property of my proxy model !!!

How it's possible ? What should I do ?

Re: How to execute some user defined codes (functions) when Django boot?

2010-08-17 Thread Mathieu Leduc-Hamel
Tang,

do you mean :

"How to execute some pieces of code when you launch the "runserver" command
by example" ? If this is what you mean, it's not a easy thing to do right
now. Then only way i found it possible is by using: twod.wsgi

With twod.wsgi you can use the entry points system of python and do, like in
Pylons, an entry defined by Paster "app_factory"

You can see an example there:
http://packages.python.org/twod.wsgi/manual/paste-factory.html#using-custom-factories

Re: Changing a model of place from the admin site

Thanks Andy,

It might be a solution and maybe the only one as you said. I'll maybe try it
or somebody propose me this other solution:

Create a subclass of the models classes i would like to move by creating
proxy objects. It force you create sometime a large number of object but it
might less dangerous to break something...

Re: Best OS - VPS environment

Yeah but it's a little bit simpler with apache and mod_wsgi...

If i don't want to run a separate service like gunicorn or something like,
how can we do the same thing than apache+mod_wsgi but with nginx.

We've tried passenger but it's not very stable and not necessarily always
product's ready.

Changing a model of place from the admin site

2010-08-16 Thread Mathieu Leduc-Hamel
Hi all,

I'm currently developing a e-commerce website using satchmo and
django. I would like to simplify the admin pannel from the user
perspective. This is why i would like to change the different group of
models. Right now, these group are organized by application. But when
using some external dependencies it some become a big mess to deal
with so many different group of options.

Is it possible

There is a example of what i would like to do. There you have a part
of my admin site hierarchy. I would like to move "Categories" and
"Discounts" from the "Product" group to the "Store" group.

auth
  Groups
  Users
Contact
  Persons
  Organizations
Product
  Categories
  Discounts
Store
  Style
  Color
  Size

How can it be done ?
