Re: PROBLEM WITH DJANGO

2018-07-18 Thread Gerald Brown

You need a command after the "manage.py" like manage.py runserver, or 
manage.py makemigrations, or manage.py migrate, or manage.py shell or 
any other commands.

You could try and convert the Windows pathnames from backslashes to 
forward slashes.


DIRS:[os.path.join(BASE_DIR,'templates)].replace('\\', '/'),

My own Windows equivalent is ...

TEMPLATES = [ { 'BACKEND': 
'django.template.backends.django.DjangoTemplates', 'DIRS': [ 
os.path.join(APPS_ROOT, 'templates/').replace('\\', '/'), ], 'APP_DIRS': 
True, 'OPTIONS': { 'context_processors': [

Re: Problem with Django TemplateDoesNotExist.

2017-11-18 Thread 'Amitesh Sahay' via Django users

Hi,
1) Its pretty obvious that the django is not able to find the required file in 
the given file path, so please it. 
2) As far as I know, the django 1.11 is supported by Python 3.6. So,  I would 
recommend you to go through the release notes of the 1.11 and use the 
recommended system configuration, otherwise if you put the code in prod env 
things may go hey-wire. For your confirmation, please take 2nd opinion on this 
part before you take any decision.

Of course, you haven't actually done any work yet. Next, start your first

You're seeing this message because you have DEBUG = True in your Django

Have you gone through the tutorial yet? It covers all of the basics that

Re: Problem with Django and python social auth

Please ignore the capital letters. The code is correct.

Re: problem with django, nginx and gunicorn

2014-05-02 Thread 'ReneMarxis' via Django users

Hello Javier

also thank you for your answer. However i do know how to implement such a
long running task for a customer.
I generaly use celery and send out an email with a link on completition of
such a task. For simple tasks i use just a cronjob. Most of those jobs run
on an separeate machine normaly.

The question is more related to gevent und unicorn. I'd like to understand
what tasks/aktions can run in paralell when using gevent in gunicorn.
Lets say there are some calls inside the app that return just some
calculated values from db. Those calls need something about 200-300 ms to
complete and doing nothing else than reading values from db and calculating
some results and presenting them with an django template.
I'm running 6 to 8 workers in gunicorn. If i understood the meaning for
using gevent correctly, the app should be able to serve more that 8 current
connections, right? Except if there are calls inside the app that block GIL
(what seems to happen for xhtml2pdf), which seems to block the gunicorn
master-worker.

I did not change anything on the django app till now. I thought gunicorn
would monkypath everything on startup. I'll probably have to investigate
some time here ...

Re: problem with django, nginx and gunicorn

2014-05-01 Thread Javier Guerra Giraldez

no, the problem isn't the GIL.   no matter the framework, language or
architecture, if you take more than a few seconds to generate an HTTP
response, users are going to complain.  the appropriate approach for
anything that takes more time is to dispatch to other process.

that's why there are so many queue managers, they make it easier to
allocate a task to be performed by other process.

the high level process should be something like this:

- user click on some "do it" button or link.  it generates an HTTP
request to do some work

- the web app (a Django View in this case) gets the request, picks any
necessary parameter and initiates a task.  the task manager responds
immediately with some ID.

- the web app immediately generates a response for the user with some
message like "process initiated, please wait"  probably shows the ID,
or maybe a link to the "is it ready" with this ID as a parameter.

- meanwhile, the task/queue manager delivers the task parameters to a
worker process.

- if the user (or some Javascript) clicks the "is it ready" link,
another Django view gets the task ID, checks the status and if it's
not ready, shows the "please wait" message.

- eventually, the task is finished, and the result (or some URL to a
produced file) is stored in the task, under the same ID

- when the "is it ready" view is hit again with this ID, it sees the
task has finished, so it redirects to the "result" URL.


about the task/queue manager, there are several available, from a
simple register in a "tasks" table and a cron task to check any
records there in the "unfinished" status (called a Ghetto queue), to
the full-featured Celery.

most of them allow you to define the tasks as simple Python functions
with a @task decorator, and simply calling it results in the queuing
of the arguments.  something like this (semi-pseudocode):


 tasks.py

from queue import task
from models import MyModelA, MyModelB

@task
def dolotsofwork(userid, modelaid, someotherarg):
user = User.objects.get(pk=userid)
modA = MyModelA.get(pk=modelaid)
.. do much more heavy processes
return "result-%d.pdf" % resultId

-- views.py

from tasks import dolotsofwork

def starttask(request, arg):
user = request.user
modela = get_object_or_404(MyModelA, pk=arg)
taskid = dolotsofwork(user.id, modela.id, ..)
return rendertemplate('pleasewait.html', {'taskid': taskid})

def isitready(request, taskid)
status = queue.taskstatus(taskid)
if status.isready():
return redirect(resulturl, taskid)
return rendertemplate('pleasewait.html', {'taskid': taskid})

def resulturl(request, taskid):
resultfilename = queue.taskresult(taskid)
return rendertemplate('processready.html', {'resultfilename':
resultfilename})

Re: problem with django, nginx and gunicorn

2014-05-01 Thread 'ReneMarxis' via Django users

Hello Erik

thanks for your responce!

I started reading a little bit related to GIL. I think this is the root of
my problem. I'm using xhtml2pdf to generate some large pdf's (up to 200
pages).
I do know i have to rewrite this code to run in background (e.g. using
celery).
However i want to understand, why gevent is blocking. As i understood,
gevent spawms a new 'microthread' that does the long lasting work. My
mistake was/is that i thought a gevent thread would be a full featured
gunicorn thread. but this can't be of course. wouldn't make sense to use
gevent otherwise ...
However this is not a big issue, as the function itself is used only in
admin by some special users. I can 'train' them to create only smaller pdf
that get created under 10 seconds ...
Nevertheless it would be nice to know, what kind of "heavy work" can be
done asynchronous with gevent. Reading the documentation i can't figure
out, where gevent would realy help improving to serve more pages/sec.
