Are you using mod_wsgi daemon mode. If not you should.

Any chance you can use 3.4

wait I will see

yes it is 3.3

GrahamDumpleton: installed the 3.4 now

Are you using daemon mode? http://blog.dscpl.com.au/2012/10/why-are-you-us...

omg this is even more difficoult

FunkyBob: Does this sound scary enough.

:)

GrahamDumpleton: I saw a neat "callable class" method for decorators recently...

toll: If you are using mod_wsgi 3.4 and daemon mode, pointing at a virtualenv is as simply as adding python-home=/usr/src/ENV to the WSGIDaemonProcess directive.

toli: ^^^

A class with a __call__ method fails in lots of ways. I should remember to show that as a bad example.

Well, __call__ method alone.

It also need to have a __get__ method as well and do various other magic to work all properly.

mattmcc, FunkyBob: you were right... that `max_length=2` was a typo. A developer just fixed it: https://docs.djangoproject.com/en/1.5/topics/db... Thanks!

GrahamDumpleton: I tested if I use daemon mod, and printed out: mod_wsgi.process_group = 'iget.be'

Am working on a decorator library that brings together all the magic I have worked out over the years.

so it is process

Hey guys I'm still struggling with an app whose models can not be edited in django-admin when DEBUG=False! what could cause that behaviour? I have no custom has_*_permission defined... (I tried to define has_change_permission(): return True which didnt help)

toli: Good, so add python-home=/usr/src/ENV to the WSGIDaemonProcess directive.

That is, the value of sys.prefix for the virtualenv.

GrahamDumpleton: to the httpd.conf ? or wsgi.py ?

To the WSGIDaemonProcess directive in the Apache configuration file.

GrahamDumpleton: so it's basically "What I learned writing the Python client for NewRelic" ? :P

ok

GrahamDumpleton: can't wait to watch the video

FunkyBob: Sort of. I have worked out some nice tricks that have incorporated back quite yet.

You want to watch my monotone and heckle me.

you know it! :P

GrahamDumpleton: so in my config now I have : WSGIDaemonProcess iget.be display-name=%{GROUP} processes=1 threads=4 python-home=/usr/src/ENV

is that good

You can remove 'processes=1'. It defaults to one process and using the processes option even if for one process causes mod_wsgi to still flag it as a multi process configuration in WSGI environment, which will stop some WSGI web browser based debuggers from working. Esoteric technical detail, so just believe me and remove processes=1.

Otherwise looks good.

BTW, if only running the one WSGI application, also set WSGIApplicationGroup %{GLOBAL}

Plus, at global scope in Apache config, outside of any VirtualHost, add WSGIRestrictEmbedded On.

That will turn of Python in Apache child process where you don't need them.

GrahamDumpleton: now I get again thiesame error ImportError: No module named django.core.wsgi

And Django is installed in the virtualenv and not separate as you had before. Is everything in the virtualenv readable to the user that your code runs as under Apache.

GrahamDumpleton: is is still separate :)

pip install Django into the virtualenv.

kk

GrahamDumpleton: I knew that is better to have the django package with your project, now it is piped in the ENV

FunkyBob: Me wonders if PyCon NZ will extend submission deadline. Cut off date supposed to be today, yet mine was proposal #16.

Never heard anyone suggest that Django itself should be a part of your project. Sounds like a really bad idea.

yes ?

tha guy who told me this, said that in this case your projects goes with the django version and there will be no confusions about it,

yesss

it works

yes

yes

omg GrahamDumpleton you are god

three days of head breaking

The only thing you should have with your projects is the pip requirements.txt file which lists the specific versions of packages you need to use. Then you build your virtualenv and go pip install -r requirements.txt.

toli: this is why we use virtualenv and requirements.txt

That way only the package list needs to be with the project.

and the right versions for it

If you aren't sure what is in the virtualenv, use pip freeze to generate the requirements.txt file.

thanks

It will list exact versions.

you are the man

well, he's the mod_wsgi man :P

:p

A small hobby of mine. :-)

heh

now, when I try to open django admin, it says unable to open database file, and the path to the sqlite file is corect

toli: https://code.djangoproject.com/wiki/NewbieMista...

toli: (a) is it a full path? (b) can the user mod_wsgi runs as write to the dir that the DB is in?

hmm

because sqlite needs to open another file there for its WAL/queue

yes I have the full path

I will check the write access

journal! that was the word I meant... not queue

I want to add a profile_image column to Django's User model. Am I right that I should do this by extending the Django's User model (https://docs.djangoproject.com/en/1.5/topics/au...) with a column that is of ImageField type?

yes

ok

I asked to confirm because some old stackoverflow threads suggest using AUTH_PROFILE_MODULE but it seems that this was deprecated in Django 1.5. Thanks!

don't believe what you read in SO

AUTO_PROFILE_MODULe was a neat tech demo, but IMHO never belonged in trunk

SO is a bunch of wannabes who cut and paste other peoples answers.

All in the pursuit of gaming the SO score.

where's the quality control? how do you know it's really a good answer, and not just a lot of people up-voting the same commonly learned mistake?

Yes, I don't blindly believe SO answers. I trust only 1.5/dev documentation :)

FunkyBob: i did it! now i'm cropping images like no tomorrow without problems!

sweet

what's the solution?

dpasting it

FunkyBob: http://dpaste.com/1207291/

FunkyBob: provino is a cropped part of a step

SignorSasso: if the file is already saved and referenced in a FileField/ImageField... you can use the field as a file

FunkyBob: mmm let me try

so step.immagine should be enough

FunkyBob: true, it works

FunkyBob: http://dpaste.com/1207293/

aaa i can remove safely File() too
