2016-02-03 Thread Denis

Hi,

I'm looking at upgrading my application from 1.6 to 1.9.2... An issue I'm
encountering now is that on Heroku, running collectstatic doesn't work on
1.9.2. The odd  things is that if I try 1.8.7 instead, it work great...


Running:
remote: python manage.py collectstatic -i docs -i tests --noinput -v 3
remote: Copying '/app/accounts/static/...js'
remote: Copying '/app/accounts/static/js'
remote: Copying '/app/accounts/static/js'
... [ Thousands of lines... ]
remote: Found another file with the destination path
'app/controllers/...js'. It will be ignored since only the first
encountered file is collected. If this is not what you want, make sure
every static file has a unique path.
remote: Found another file with the destination path
'app/controllers/js'. It will be ignored since only the first
encountered file is collected. If this is not what you want, make sure
every static file has a unique path.
remote: Traceback (most recent call last):
remote: output = self.handle(*args, **options)
remote:   File
"/app/.heroku/python/lib/python2.7/site-packages/django/contrib/staticfiles/management/commands/collectstatic.py",
line 176, in handle
remote: collected = self.collect()
remote:   File
"/app/.heroku/python/lib/python2.7/site-packages/django/contrib/staticfiles/management/commands/collectstatic.py",
line 114, in collect
remote: level=1,
remote:   File
"/app/.heroku/python/lib/python2.7/site-packages/django/contrib/staticfiles/management/commands/collectstatic.py",
line 201, in log
remote: self.stdout.write(msg)
remote:   File
"/app/.heroku/python/lib/python2.7/site-packages/django/core/management/base.py",
line 111, in write
remote: self._out.write(force_str(style_func(msg)))
remote: IOError: [Errno 11] Resource temporarily unavailable


I do have a lot of static file... Unsure that matter.

An other things is that it doesn't seem to fail at the same point in the
collectstatic command every time I run it. So look like it's failing on
different file every time I run it...


I did find this: https://github.com/etianen/django-require/issues/20
But I actually don't use django-require... (It's not in my requirement.txt
of what I install on Heroku)


I also see it fail (sometime but much less often as the "Resource
temporarily unavaible" error this way:
remote: Found another file with the destination path 'accounts/..html'. It
will be ignored since only the first encountered file is collected. If this
is not what you want, make sure every static file has a unique path.
remote: Found another file with the destination path 'accounts/...js'. It
will be ignored since only the first encountered file is collected. If this
is not what you want, make sure every static file has a unique path.
remote: Traceback (most recent call last):
remote:   File "manage.py", line 10, in 
remote: execute_from_command_line(sys.argv)
remote: utility.execute()
remote: self.execute(*args, **cmd_options)

Which is even less helpful in figuring out what's going on...


So I'm looking for some though on what this error mean and how to debug it
further. We never encountered that error when on 1.6. Testing on 1.8.7
works fine but then if I only change the Django version (nothing else) to
1.9.2, I start getting that error...


Thanks everyone!

If you don't have access to the shell, why are you concerned with the
django version?

 Hello Denis,

 This issue  is not related  to the  django-require.  Look like you have
two  files (with  same name ) at the different paths. New  collect static
is trying to colelct both files and can not decided  which one should be
used.
Could you please  send part of the section  STATICFILES_DIRS and
INSTALLED_APP ?

Many thanks,

Serge

If you save the living environment, the biodiversity that we have left,
you will also automatically save the physical environment, too. But If
you only save the physical environment, you will ultimately lose both.

1) Don’t drive species to extinction

2) Don’t destroy a habitat that species rely on.

3) Don’t change the climate in ways that will result in the above.

Scaling Django

2016-02-03 Thread Joshua Pokotilow

At the startup where I work, we've written a lot of our server code in
Django. So far, we've adopted a "build it fast" mentality, so we invested
very little time in optimizing our code. A small amount of load testing has
revealed our codebase / infrastructure as it stands today needs to run
faster and support more users.

We recently hired some new engineers who are extremely skeptical that we
should optimize our existing code. Their main concerns are:

- We need to move to a service-oriented infrastructure because Django is
too monolithic (monolithic = technology lock-in & difficult to troubleshoot)
- It's too easy to write slow queries using the Django ORM
- It's hard to hire Django engineers
- While Instagram and DISQUS use Django to service large numbers of people,
they don't use it for any serious backend work

After having worked with Django for the last 3 years, I'm a big believer in
it, and I believe it would scale. To defend my position, I've pointed out
to my colleagues that it's easy to identify bottlenecks with tools like the
Django Debug Toolbar and Yet Another Django Profiler. With my colleagues
present, I've isolated and fixed significant speed problems inside of a few
hours. I don't believe the Django ORM is inherently bad, although I do
think that coders who use it should Know What They're Doing. Finally, I've
referenced blog entries that talk about how Instagram and Disqus use Django
on the backend for backend-y tasks.

Despite my best efforts, my colleagues are still pushing to have us rewrite
large portions of our infrastructure as separate services before we try to
fix them. For example, we have one slow REST endpoint that returns a
boatload of user data, and so there's talk about using a new microservice
for users in lieu of our existing Django models. Even if we are able to fix
bottlenecks we encounter in a timely fashion, my colleagues fear that
Django won't scale with the business.

I'm writing this post to garner additional evidence that Django will scale.
Anything compelling (and preferably not obvious) that would help shed some
light on Django's ability to scale would be *greatly* appreciated, as it's
very difficult for me to defend my position that Django is a viable
long-term solution without solid evidence to back up my claims. It
certainly doesn't help that I don't have any experience scaling Django
myself!

Thank you.
