Printing to console from async method inside django channels

[Chris Barry]

I'm trying to print inside these methods in from this example in django 
channels:

https://github.com/andrewgodwin/channels-examples/blob/master/multichat/chat/consumers.py

But nothing is coming through to the console.

I haven't worked with python Async before, so I'm not sure if I'm doing 
something really stupid? The examples in the python docs seem to show 
prints working no problem

Re: Trouble deploying Django (project folder, wsgi.py and libapache2-mod-wsgi)

[Jason]

you need to use libapache2-mod-wsgi-py3, since the package you used is for 
python2 only

Well, is it actually named profile inside the view? Rather than the default 
original? Check if the name is right and your profile is named profile in the 
template.

If you actually are inside the profile create view, the profile probably does 
not have an id yet and thats why the url lookup is failing. The ID will be 
created on first save of the object.

Trouble deploying Django (project folder, wsgi.py and libapache2-mod-wsgi)

[drone4four]

I’m having some issues deploying Django.


Here is my site: https://daniel496.agency/ 


I’m running a Digital Ocean Droplet with Ubuntu 14.04 and Python v3.4 with 
Django 2.0.2 installed.


In this post first I share what errors I am encountering, then what I think 
is the issue is and then what I’ve tried to resolve the issue.  At the end 
of this post are my configuration files like ssl.conf and wsgi.py.


Before I begin, I think the issue might involve the naming of my project 
folders. My project folder on my local machine is named: 
`first_project_attempt`.  But on my remote server, the project folder is 
named, `cel2fah`. I copied the contents locally to my remote host and now 
trying to iron out the issues.


Here I go.  If you access my site linked to above, right now it is showing:


Internal Server Error
> The server encountered an internal error or misconfiguration and was 
> unable to complete your request.
> Please contact the server administrator at @gmail.com to inform them 
> of the time this error occurred, and the actions you performed just before 
> this error.
> More information about this error may be available in the server error log.
> Apache/2.4.7 (Ubuntu) Server at daniel496.agency Port 443


Here are the last ~50 lines of my apache error log file: 
https://pastebin.com/UPsTmf28 


I’m thinking that there could be a potential conflict between 
libapache2-mod-wsgi and libapache2-mod-wsgi-py3.  I encountered a similar 
issue a few weeks ago. There are apparently still traces of 
libapache2-mod-wsgi (for Python 2.7) still flagged as active on my system 
given that $ sudo dpkg -s libapache2-mod-wsgi prints:

However when I go to remove it, it says it’s not installed:


$ sudo apt remove libapache2-mod-wsgi

More to the point, when invoking this as root:


apache2ctl -t -D DUMP_MODULES


...it lists what modules apache2 has loaded. And libapache2-mod-wsgi (for 
Python version 2) is included.  So I Google ‘how to remove apache modules’ 
which turns up this SO post: 
https://stackoverflow.com/questions/9288865/how-can-i-uninstall-an-apache2-module

So I set out to rename my libapache2-mod-wsgi.so (for Python version 2) 
from my apache2 modules directory inside /usr/lib. I see a symlink 
mod_wsgi.so which refers to mod_wsgi.so-3.4:


@:/usr/lib/apache2/modules$ ls -la mod_wsgi*
> lrwxrwxrwx 1 root root 15 Nov 18 2014 mod_wsgi.so -> mod_wsgi.so-3.4
> -rw-r--r-- 1 root root 174448 Nov 18  2014 mod_wsgi.so-3.4
> @:/usr/lib/apache2/modules$ 


So is my Apache serving the libapache2-mod-wsgi module for python2 or just 
for python3 or what?


What else can you people determine could be the issue here?


Here is my wsgi.py:

> """

> ``application``.

application = get_wsgi_application()

Re: how to do inner join using 3 tables

[Simon Charette]

Hello Angel,

Did you try the following

transaction = Transaction.objects.filter(
user=user,
status=F('detail__status'),
).first()

Best,
Simon

Re: how to do inner join using 3 tables

[C. Kirby]

As written it looks like you want to get all the 0 status transactions for 
a given user, and then get all the transaction details for those 
transactions (.filter allows for any number of results) Since your var 
transaction is a list, and you really only care about the ids to pull the 
transaction details, you should have your code like this:

def get_object(self, pk):
user = User.objects.get(id=pk)
transactions = Transaction.objects.filter(user_id=user.id, 
current_status=0).values_list('id', flat=True)
return Transaction_Detail.objects.filter(transaction_id__in=transactions
, status=0)

how to do inner join using 3 tables

[Angel Rojas]

Hello friends, I have a little problem with a relationship with 3 tables

tables
- User
- Transaction
- TransactionDetail

my query is

class TransactionInitiated(generics.ListAPIView):
"""

"""
serializer_class = TransactionSerializer

def get_object(self, pk):
user = User.objects.get(id=pk)
transaction = Transaction.objects.filter(user_id=user.id, 
current_status=0)
# Transactiondetail.objects.filter(transaction_id=transaction.id, 
status=0)
return Transaction.objects.filter(user_id=user.id, 
current_status=0).order_by('-id')

def get(self, request, pk, format=None):
current_user = request.user
list_trans_init = self.get_object(current_user.id)
serializer = TransactionSerializer(list_trans_init, many=True)
return JsonResponse({'data': serializer.data}, safe=False)


with this query I recovery all user with a respective transaction, but I 
don't how to use inner join in here, I try next


def get_object(self, pk):
user = User.objects.get(id=pk)
transaction = Transaction.objects.filter(user_id=user.id, current_status=0)
return Transaction_Detail.objects.filter(transaction_id=transaction, 
status=0)

Re: How do I transmit any changes to databases(i.e. creates and updates pertaining to a particular user) using Django Channels?

[Andrew Godwin]

Hi Alexis,

You'll need to do some work yourself - hook into database changes (either
via signals or overriding the save method) to send change notifications to
a different Group for each user (maybe use group names like "user-123213",
where the number is their ID).

Then, when someone connects via a socket or long-poll, add their consumer
to the group and listen for the change message. You can see some docs on
this here:
http://channels.readthedocs.io/en/latest/topics/channel_layers.html and an
example of sending messages to groups (albeit from another consumer rather
than a save method) here:
https://github.com/andrewgodwin/channels-examples/tree/master/multichat

Re: Reverse for 'detail' with arguments '('',)' not found. 1 pattern(s) tried: ['(?P[0-9]+)/$']

[Andy Grabow]

Well, is it actually named profile inside the view? Rather than the default
original? Check if the name is right and your profile is named profile in
the template.

How do I transmit any changes to databases(i.e. creates and updates pertaining to a particular user) using Django Channels?
