Re: How to run background application via Django

[Sugita Shinsuke]

Hi Vijay Khemlani

I tried tutorial. and "error: timed out" was disappeared!

http://celery.readthedocs.org/en/latest/django/first-steps-with-django.html
was deprecated.

http://docs.celeryproject.org/en/master/django/first-steps-with-django.html
is new.

I added the code in my app/__init__.py:

---
from __future__ import absolute_import

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from .celery import app as celery_app
---

How do I call other process?

Is it okey?

@shared_task
def my_task():
cmd = "cd program_path;python my_program.py"
import subprocess
proc = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, 
stderr=subprocess.STDOUT)
return proc


I call my my_task function in the view

---
def run_celery(request):
result = my_task.delay()
while not result.ready():
print 'processing...'
print result.get()

return HttpResponse("test")

 Hi,
 i am trying to update data in a row from an existing database but i
 keep getting this error.

 update_form() takes exactly 2 arguments (1 given)

 can someone advise what i am missing here.


 here are my code:

 view.py

 def update_form(request, id):
 if request.method == 'POST':
 a=newleave.objects.get(id=id)
 form =leave_application(request.POST, instance=a)
 if form.is_valid():
form.save()
 return HttpResponseRedirect('successful.html')
 else:
 a=newleave.objects.get(id=id)
 form = leave_application(instance=a)
 return render_to_response('update_form.html', {'form': 
 form},context_instance=RequestContext(request))

 form.py

 class leave_application(forms.ModelForm):
 class Meta:
 model =newleave
 fields =('First_Name', 'Last_Name', 'department', 'position', 
 'leave_type', 'Specify_details', 'start_Date', 'end_date', 
 'total_working_days', 'username')



 model.py

 class newleave(models.Model):
 First_Name = models.CharField(max_length=45)
 Last_Name =models.CharField(max_length=45)
 department=models.CharField(max_length =45)
 position=models.CharField(max_length =45)
 leave_type =models.CharField(max_length=45)

Return to the requested page after successfull @login_required by the next variable

[Robin Lery]

Suppose this is the url after
`@login_required(login_url='/accounts/required_login/')`:

http://ngoksy.com/accounts/login_required/?next=/article/

view for the login_require:


*def required_login(request):return render(request,
'required_login.html')*

I tried adding 'next', like it [here][1]:



*def required_login(request):c = {'next' :
request.GET.get('next', '/')}return render(request,
'login_required.html', c)*

But it didn't help.

I have different template for login and another template for anonymous user
which is redirected by `@login_required`.

required_login.html:
















*   Login required! You must login to view the content.{%
if form.error %}Sorry, invalid
username/password!{% endif %}{%csrf_token%}
Username:Password:*

I want to pass the `next` variable after successful login of
`login_required()`, and land into Articles page after that. How do I do
that? Please help me understand. Your help will be greatly appreciated.
Thank you!

Re: How to run background application via Django

[Sugita Shinsuke]

Hi Vijay Khemlani

Thank you for replying. 

>Have you done the celery tutorial?
I have not done the celery tutorial yet.

But, I ran Redis and set below in my settings.py

BROKER_URL = 'redis://localhost'
CELERY_RESULT_BACKEND = 'redis'
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'
CELERY_ACCEPT_CONTENT = ['json']

I also ran celery command.

celery -A app_name worker -l info 


Is it the tutorial URL you said?

http://celery.readthedocs.org/en/latest/django/first-steps-with-django.html

Thank you.

 Hi there.

 I'd like to run background application.

 I coded this code.

 I wrote the urls.py and I added in the view.

 def run_junix(request):
 cmd = "cd app_path;nohup python background_app.py &"
 import subprocess
 proc = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, 
 stderr=subprocess.STDOUT)

 return HttpResponse("bg test")

 Is it good way? or using supervisor or, if you know the better way, 
 would you tell me?

 Anyone who know this matter, please help.

Re: How to run background application via Django

[Vijay Khemlani]

Have you done the celery tutorial?

Async tasks require you to have a broker (rabbitmq or something) and also
to create some workers that actually execute the task.

Re: updating data in a row

[Vijay Khemlani]

You have two choices

1. Change the URL mapping and pass the "id" in the url

url(r'^update_form/(?P\d+)/$', 'eLeave.views.update_form'),

(then the url is something like /update_form/15/)

2, Change the view so that it only accepts the "request" argument

def update_form(request):

in that case you can pass the id in the POST body of the request

Re: Pulling data from two table

[Vijay Khemlani]

Well, you can do something like this

one_leave = leave.objects.get(pk=1) # Asuming there is a leave with pk 1
print one_leave.staff.First_Name# Automatically joins with the staff
table to print the first name of the associated staff

Or something like this

one_staff = staff.objects.get(pk=1) # Asuming there is a staff with pk 1
staff_leaves = one_staff.leave_set.all()
for staff_leave in staff_leaves:
print staff leaves# Print all the leaves of a
particular staff

Also, I recommend you to follow Python and Django naming conventions, that
is classes in CamelCase ("Staff" and "Leave" instead of "staff" and
"leave") and fields in underscore (first_name instead of First_Name, etc)

Re: How to run background application via Django

[Sugita Shinsuke]

Hi somecallitblues 

Thank you for replying.
I installed Celery 3.1.17.

And, I setup 

I created add method in tasks.py

my tasks.py

from __future__ import absolute_import

from celery import shared_task


@shared_task
def add(x, y):
return x + y


I also called my add method from my view.

hoge_view.py
---
def run_celery(request):
result = add.delay(3, 8)
while not result.ready():
print 'spam'
print result.get()
return HttpResponse("test")
---

I called it from url.

"error: timed out" was occurred.

Why is it timed out? Could you help me?

Looks like you aren't sending enough arguments to your view from the URL

That command attempts to install Django for the systemwide python. On
ubuntu this would require sudo(root) priveleges.

sudo pip install django

While that will work, I suspect most people would recommend you use
python virtualenv in order to create python sandboxes. The biggest
benefit is that you can have multiple django versions, each in their own
sandbox (great for testing and upgrades).

Here's a tutorial

Enjoy,
Alex

Re: what's different between {% static %} and {{ STATIC_URL}}

[Florian Schweikert]

On 2015-01-06 12:55, Andreas Kuhne wrote:

The difference is the age of the django project you are looking at. {%
load staticfiles %} the {% static %} is the current way to load and
use static files. It also has the option to do other things (like MD5

Also {% static %} works with your 500.html
As there is no context accessible if an 500 happen, {{ STATIC_URL }} is 
not available.

As per the Django installation guide, I have installed pip using "sudo

Re: Model to create forms

[Lorenzo Bernardi]

Hello,

this is what _relational_ databases are built for.  if you have two
tables, one for the description of the experiment (one record per
experiment), and another for the statistics (one record per data
sample, with a foreign key to the experiment record); then fetching
the description of the experiment, plus all the related data will be
much faster, simpler, more compact and all-around more efficient than
having one table per experiment.
it looks to me that the resulting code should be more compact but more 
difficult to write and maybe too clever for me. I'm writing this code 
for someone who is not completely sure of what he really wants (I mean 
the data that should be stored in the table) and  so the code should be 
able to accept some change in the definition of the experiments without 
breaking the old data.

databases aren't flat files, use them as designed and they'll perform very well.


I agree with that. My main worry is that I'm not so familiar with 
databases and I hope I can estimate if the code will perform well in 
real condition when I'll do some limited tests.


thanks  for the information and I'll give it a try

sincerely

L.

Re: Model to create forms

[Lorenzo Bernardi]

Hello,

1) there is no other approach (like creating a model on the fly, that 
is not writing in models.py. But it looks against the way django 
works) and any idea is welcomed.


Generally I've found that creating a real model to store the data is 
easiest in the long run and usually involves less programming.
It definitely looks easier for me to code a model per experiment. But 
I'm writing this app for seomeone else and I foind it will be easier to 
give to this person the opportunity to create by himself the definition 
of the experiment. Of course it means my app should be rather simple to 
make it handle this (adding or substracting field of the form or 
changing things ) without loosing the data and this is where I don't 
know if I can really program this. I'll try with a simpler version and 
look again at our advice after some tests.


2) Also keeping all the experiments data in only one table and getting 
all the information for one experiment by finding all the row with the 
same uid looks a little bit a time consuming process but for now we 
used the bureaucracy plugin for the last six month and it doesn't look 
like it is slowing down too much the response of the wiki so it might 
not be so inefficient after all. Maybe it will scale badly. Here again 
any advice is welcomed.


Databases are usually good at this sort of thing. It shouldn't be a 
problem, but might require some database tuning.



OK.
3) The data to create the form is stored in a table (as a say, like a 
recipe) and so will it be better to create the form in the views.py or 
in the template (in that case in the view I gather the field 
definitions and then in templates loops through the table and create 
the widget at that time).


Again, it's possible to do this, but it's hard. Are all of the fields 
just plain text fields, or are some choice fields?


there are some choice field, and date field but may be I can gather some 
common field in the definition of the experiment.


thanks for the information

sincerely

Re: porting to 1.7

[Collin Anderson]

Hi,

In your INSTALLED_APPS, be sure you have 'jadeempire.smartpages' instead of 
'smartpages'.

Also, any time you refer to a view, or any other import, be sure to always 
use the "jadeempire" prefix.

Re: Expected performance of the django development server?

[Collin Anderson]

Hi Richard,

Like you've seen, the _number_ of queries often has a large effect on speed.

Also, try comparing your page load time with and without debug toolbar 
enabled. I found that DDT is slow itself :).

Re: Filter_horizontal, applying filter on the right box - chosen items

[Collin Anderson]

Hi,

It's a bit hacky, but I've used filter_horizontal outside of the admin 
before.

from django.contrib.admin import widgets

class MyForm(forms.Form):
users = forms.ModelMultipleChoiceField(
required=False,
widget=widgets.FilteredSelectMultiple(verbose_name='Field Name', 
is_stacked=False),
queryset=choices_qs,
initial=initial_qs,
)


function addEvent(obj, evType, fn){obj.addEventListener(evType, fn, 
false)}
{{ form }}
https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js";

Re: Deploying Django on Docker

[Jeroen Bakker]

Hi Anssi,

Not really an answer to your question, but just to give you insight to a 
solution.


We at l1nda are using docker and django with small applications and 
large applications.


We developed an nginx container and uwsgi container and a devops 
container. The devops container does all the tricky parts and the nginx 
and uwsgi containers are basically simple ones.


We have automated the deployment docker (devops) image that internally 
uses docker-py that will minimize the downtime of the django containers. 
The script is just a python file of 100 lines that brings application 
down and up in a redundant way it also starts the staticscollecting etc. 
As it is pulling the images from another server (at our office), the 
security hurden is small.


1. Pull new images from our private repository
2. Collect statics, update databases etc.
3. loop per container [we run every application in 4 different containers]
3.1 stop old container
3.2 start new container.

We use a shared FS (NFS) for sharing the resources (uwsgi is allowed to 
write to the FS and the nginx is only allowed to read from the FS. The 
machine that contains the nginx image is also hosting the FS.

For a long time I have been battling with the following problem: how 
to deploy Django in an easy, maintainable, secure and reliable way for 
small Django applications. The applications I write are mainly very 
low traffic, and often they are coded in a couple of days. 
Unfortunately the hardest part of producing these applications has 
been deployment. A big part of the problem is that I have to work with 
RHEL6 based servers, and those tend to have old libraries.


The solution I am currently using is a nice little setup helper I 
wrote, django-dockerfile: 
https://github.com/akaariai/django-dockerfile. The idea is that you 
write a environment file for each server you want to deploy into, and 
after that everything happens automatically through usage of fab.


The solution works great for me even if there is still a lot to do. 
For example, usage of the fig package could make the code more robust, 
and allow for multi-server installations.


The main reason I am writing here on django-users is that I would like 
to see an easy way to deploy small Django applications. For large 
applications it seems OK to just build up your own deployment 
strategy, but for small applications it is too easy to end up doing 
the deployment in a hackish way where for example deploying the 
application isn't scripted, and each application's deployment strategy 
varies slightly.


I am looking for a way to deploy Django with at least these features:
  - Allows one-command deployment directly from Git to Docker-enabled 
server

  - Easy to use and get started
  - Doesn't use development server, or SQLite as database.
  - Does care for security
  - Media and static files served properly (note: CDN is overkill for 
my projects!)
  - Allows one to define secrets and other environment variables per 
installation

  - Preferably: logging, backup and restore thought out

The django-dockerfile package has the above features except for 
logging, backup and restore.


So, if there already exists something that has the above features 
implemented, then please tell me. If not, I am looking for interested 
developers to participate in building a tool for the small Django 
project deployment use case. The django-dockerfile package could be 
used as basis for the work, but using some other package or just 
starting from scratch are also options. Just writing a blog post that 
has information about an example Django deployment with every aspect 
of the above feature list covered could be enough.

Re: django form field validation and error display

[Edgar Gabaldi]

There is not your problem, but maybe will be in future. The best way to
clean fields that depend of other fields is override the clean method of
form.

For a long time I have been battling with the following problem: how to
deploy Django in an easy, maintainable, secure and reliable way for
small Django applications. The applications I write are mainly very low
traffic, and often they are coded in a couple of days. Unfortunately the
hardest part of producing these applications has been deployment. A big
part of the problem is that I have to work with RHEL6 based servers, and
those tend to have old libraries.

The solution I am currently using is a nice little setup helper I wrote,
django-dockerfile: https://github.com/akaariai/django-dockerfile. The
idea is that you write a environment file for each server you want to
deploy into, and after that everything happens automatically through
usage of fab.


Have you seen Mezzanine fab deployment? Ken Bolton has blogged about it ...

http://bscientific.org/blog/mezzanine-fabric-git-vagrant-joy/

Mike




The solution works great for me even if there is still a lot to do. For
example, usage of the fig package could make the code more robust, and
allow for multi-server installations.

The main reason I am writing here on django-users is that I would like
to see an easy way to deploy small Django applications. For large
applications it seems OK to just build up your own deployment strategy,
but for small applications it is too easy to end up doing the deployment
in a hackish way where for example deploying the application isn't
scripted, and each application's deployment strategy varies slightly.

I am looking for a way to deploy Django with at least these features:
   - Allows one-command deployment directly from Git to Docker-enabled
server
   - Easy to use and get started
   - Doesn't use development server, or SQLite as database.
   - Does care for security
   - Media and static files served properly (note: CDN is overkill for
my projects!)
   - Allows one to define secrets and other environment variables per
installation
   - Preferably: logging, backup and restore thought out

The django-dockerfile package has the above features except for logging,
backup and restore.

So, if there already exists something that has the above features
implemented, then please tell me. If not, I am looking for interested
developers to participate in building a tool for the small Django
project deployment use case. The django-dockerfile package could be used
as basis for the work, but using some other package or just starting
from scratch are also options. Just writing a blog post that has
information about an example Django deployment with every aspect of the
above feature list covered could be enough.

Re: django form field validation and error display

[James Schneider]

Oh, you are passing a URL to render() instead of a template name. Try
something like this:

return render(request, 'signup.html', {'form': signup_form})

Sorry, didn't catch that the first time.

Can it be possible that you are rendering a different template (without 
CSRF) for the mobile version?

Re: I can send mail with shell but can't sent mail via view

[James Schneider]

After a bit of reflection, I actually think the 'telnet' test would be a
good one to run before troubleshooting your code any further. Many ISP's
block port 25 going out to the Internet because that is the default port
used for SMTP communication between SMTP servers to relay mail. Spammers
use this port to directly send mail to remote servers, hence the reason it
is blocked. I would try 587 as an alternative, as it appears your mail
provider offers it. You may still need to set EMAIL_USE_TLS to False for it
to work though. If you run the 'telnet mail.pep.co.ir 25' test and it comes
back with 'connection refused' or just seems to hang without displaying the
"220 CMS5...", then the alternate port will likely be (at least part of)
your solution.

Sorry to get so far down into the technical muck, but these are the things
that I would be trying in your situation.

Deploying Django on Docker

[Anssi Kääriäinen]

For a long time I have been battling with the following problem: how to 
deploy Django in an easy, maintainable, secure and reliable way for small 
Django applications. The applications I write are mainly very low traffic, 
and often they are coded in a couple of days. Unfortunately the hardest 
part of producing these applications has been deployment. A big part of the 
problem is that I have to work with RHEL6 based servers, and those tend to 
have old libraries.

The solution I am currently using is a nice little setup helper I wrote, 
django-dockerfile: https://github.com/akaariai/django-dockerfile. The idea 
is that you write a environment file for each server you want to deploy 
into, and after that everything happens automatically through usage of fab.

The solution works great for me even if there is still a lot to do. For 
example, usage of the fig package could make the code more robust, and 
allow for multi-server installations.

The main reason I am writing here on django-users is that I would like to 
see an easy way to deploy small Django applications. For large applications 
it seems OK to just build up your own deployment strategy, but for small 
applications it is too easy to end up doing the deployment in a hackish way 
where for example deploying the application isn't scripted, and each 
application's deployment strategy varies slightly.

I am looking for a way to deploy Django with at least these features:
  - Allows one-command deployment directly from Git to Docker-enabled server
  - Easy to use and get started
  - Doesn't use development server, or SQLite as database.
  - Does care for security
  - Media and static files served properly (note: CDN is overkill for my 
projects!)
  - Allows one to define secrets and other environment variables per 
installation
  - Preferably: logging, backup and restore thought out

The django-dockerfile package has the above features except for logging, 
backup and restore.

So, if there already exists something that has the above features 
implemented, then please tell me. If not, I am looking for interested 
developers to participate in building a tool for the small Django project 
deployment use case. The django-dockerfile package could be used as basis 
for the work, but using some other package or just starting from scratch 
are also options. Just writing a blog post that has information about an 
example Django deployment with every aspect of the above feature list 
covered could be enough.

Re: I can send mail with shell but can't sent mail via view

[James Schneider]

Thanks.

I can see from the traceback that you have EMAIL_USE_TLS set to True, but
you also have EMAIL_PORT set to 25. It doesn't appear that your email
server supports TLS via port 25:

$ openssl s_client -starttls smtp -connect mail.pep.co.ir:25
CONNECTED(0003)
didn't found starttls in server response, try anyway...


I checked the other standard ports (tcp/465 and tcp/587) and they don't
seem to offer SSL/TLS encryption either. I wouldn't necessarily recommend
setting EMAIL_USE_TLS to False, although you could instead set
EMAIL_USE_SSL to True and see if that works for you.

My guess is that your SMTP host does not support any sort of encrypted
connection. I would check their documentation to see if that is the case.
You can also check your (working) email client settings (assuming you are
using the same SMTP server) to see if any SSL/TLS settings are enabled. If
neither SSL or TLS are enabled in your client (which I suspect is the case
unless you are using MAPI/RPC via MS Outlook/Exchange), then you may
consider setting EMAIL_USE_TLS to False and re-run the test. Note that this
will send your password across the Internet in clear text (unless the
server is using CRAM-MD5 for challenge/response authentication, but still
not a great idea). You could potentially change your SMTP password
temporarily when you disable EMAIL_USE_TLS and change it back afterwards to
be safe. If there is no encryption set in your email client, I wouldn't
worry about changing the password since your email client is probably
sending it out every 10 minutes anyway.

When you say 'python shell' do you mean an actual Python shell (ie. just
typing python and manually importing the send_mail function) or are you
starting a Python shell via 'python manage.py shell'? If you are using a
vanilla python shell (no manage.py), the send_mail function may be relying
on defaults since it won't take into account your settings.py file (which
may try to relay through a local SMTP server on localhost, I haven't
looked). If you are starting it through the manage.py shell, then I'm not
sure where to go from there other than twiddling the settings I mentioned.

Does the traceback come back immediately when you execute the view, or does
it seem like it needs a fair amount of time to 'time out' (several seconds
or probably more)? If it is the former, we're probably still looking at a
DNS problem, if it is the latter, my guess is the EMAIL_USE_TLS variable
being set to True.

Since you have shell access, you could also potentially test the connection
directly using the command:

$ telnet mail.pep.co.ir 25
Trying 79.175.161.174... Connected to mail.pep.co.ir. Escape character is
'^]'. 220 CMS5 HighMail ESMTP Service, Version: 2008.8.0.0.4 ready at Thu,
8 Jan 2015 13:55:59 +0330 ehlo pep.co.ir 250-CMS5 says hello 250-DSN
250-AUTH LOGIN CRAM-MD5 250-AUTH=LOGIN 250 ok

I typed 'ehlo pep.co.ir' after the initial connection to show the various
authentication schemes and operations offered by the SMTP server. Just type
quit to exit. If you do test it, as long as you get the "220 CMS5 HighMail
ESMTP..." line, you should be in good shape. Normally I would expect to see
"250-STARTTLS" as one of the options (indicating TLS is supported).

Another option would be to try using the IP rather than the name for
EMAIL_HOST. In this case it would be '79.175.161.174' from your nslookup
command earlier. This 'should' bypass the DNS query to resolve the
EMAIL_HOST to an IP address (since it is already an IP). If that works,
then you definitely have some kind of DNS issue.

How to run background application via Django

[Sugita Shinsuke]

Hi there.

I'd like to run background application.

I coded this code.

I wrote the urls.py and I added in the view.

def run_junix(request):
cmd = "cd app_path;nohup python background_app.py &"
import subprocess
proc = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, 
stderr=subprocess.STDOUT)

return HttpResponse("bg test")

Is it good way? or using supervisor or, if you know the better way, would 
you tell me?

Anyone who know this matter, please help.

Thank you for your reply, it seems that every thing is ok:
$ nslookup mail.pep.co.ir 

Server: 10.252.84.50
Address:10.252.84.50#53

Non-authoritative answer:

and:

$ python manage.py shell

>>> import socket

'79.175.161.174'

I attach the whole traceback with this reply.thank you.

Re: CSRF verification failed when I use smart phone

[Sugita Shinsuke]

Hello Vijay Khemlani 

Thank you for replying.
But, of cause I appended the tag in my form like below


{% csrf_token %}

but I wonder about that using the iframe is bad.

The form is child of iframe.

I also checked Chrome's developer tool.
The csrf token was saved in the cookie.

Re: I can send mail with shell but can't sent mail via view

[James Schneider]

Can you send the whole traceback?

Name resolution errors indicate an issue with DNS reachability, or a domain
name incorrectly entered somewhere. I'm assuming that you are running the
shell on the same server that is running your Django instance? You should
be able to do the following on the server where Django is running:

$ python manage.py shell
>>> import socket
>>> # checks if name resolution is working at all
>>> socket.gethostbyname('www.google.com')
'74.125.20.105'
>>> # note you may get a different IP address
>>>
>>> # check if your email host value is resolvable
>>> socket.gethostbyname("mail.xx.ir")
Traceback (most recent call last):
  File "", line 1, in 
gaierror: [Errno -5] No address associated with hostname
>>>

Obviously I received an error here since I used the masked value you
provided. You should get an IPv4/IPv6 address back, or an error similar to
the one you posted.

You can also do a quick check if you have shell or command prompt access
available on your server outside of Python:

$ nslookup www.google.com
Server: 127.0.1.1
Address: 127.0.1.1#53

Non-authoritative answer:
Name: www.google.com
Address: 74.125.239.112
Name: www.google.com
Address: 74.125.239.114
Name: www.google.com
Address: 74.125.239.113
Name: www.google.com
Address: 74.125.239.116
Name: www.google.com
Address: 74.125.239.115

$ nslookup mail.xx.ir
Server: 127.0.1.1
Address: 127.0.1.1#53

** server can't find mail.xx.ir: NXDOMAIN

An NXDOMAIN response means that the domain is either typed incorrectly, or
just doesn't exist out on the wild Internet (or wherever your DNS server
recursively looks for you)

That command should work on Windows and most Linux distributions (some
Linux systems include the 'host' command as an alternative if BIND tools
are installed). The output may be formatted differently but should provide
similar information.

The full traceback for the error will likely be most helpful, though.
