Re: Add single object(most recent) from foreign key relationship to django queryset

[Andrew Kos]

Could you do a separate query or use select_related() to retrieve the most 
recent comment then combine the two in your table building logic? You're 
going to be constrained by the structure of the models anyways and so will 
probably have to make a couple queries to the DB.

how to initialize input form fields using URL parameters

[Andrew Brown]

I am trying to pass initial values to my form set via URL Query
ex) Localhost:8000?/First_name_id_0=Samuel
[image: forms.py.png]

I was told to use the initial parameter and not the instance in my view 
first

"An inline formset is related to one instance of the parent model. You 
identify *which* instance the formset is related to by the “instance” 
parameter. The “initial” parameter has a different usage, which is defined 
in the docs."

But I can't seem to find an examples in the docs
[image: Views.py.png]

How do I change my view so that that it initialize my form set with URL 
Query?

missing field after makemigrations

[andrew snyder]

There is something in my models.py that breaks makemigrations.

The field "rank" is missing from "CharacterSkill".  Also, if I uncomment 
any of the three classes that refer to "Character" the "game" and "player" 
fields become separate items in the migrations file.

OperationalError at /admin/login database or disk is full

[Andrew Rea]

Hello!

This is my first post in this group so be gentle. 

I'm creating a new Django project, and I've successfully created a 
superuser. But when I try to access the Admin page of my project with my 
superuser credentials, I receive this error:

OperationalError at /admin/login/ 
database or disk is full

Is this because my SQLite database is full from other projects? Or possibly 
because I have too many virtual envs from those same other projects? *Or* is 
it due to my personal computer's disk being too full?

Thank you in advance,

Andrew S. Rea

Re: Async Help Needed

[Andrew Godwin]

The example you presented should Just Work - that error generally only occurs 
if you return an un-awaited coroutine, which if you're just returning a 
response, should be impossible.

What version of Python and Django are you running?

Re: register_converter doesn't work with ASGI

[Andrew Godwin]

Ah yes, that's because the URL parsing/conversion all happens in the main 
(async, in ASGI mode) thread - and because to_python is a a synchronous 
function interface, there is literally nothing you can do to make it work.

The only real way of fixing this would be for Django to patch the URL 
converters and run them all in a synchronous mode unless they were decorated as 
"safe" somehow, much like we do for middleware. It's not a terribly hard patch 
to make, but it does mean you don't have an immediate solution. There are ways 
of trying to work around it, but they will all result in you blocking the async 
thread while the ORM query runs, which would be disastrous in production.

My apologies for not getting this in for the original async view patch - I had 
forgotten converters ran in the URL resolver.

This is probably this error:

[Andrew Godwin]

The tracebacks are there somewhere, you might have to look at the raw HTTP 
response in the browser to see them.

Re: Daphne raises Internal Server Error when accessing static files from development server

[Andrew Godwin]

asgiref 3.3.2 introduced stricter checks for what an async function is, so I 
would imagine that's the problem. 3.3.3 fixes some of them, but I'm guessing 
you might have a different flavour of problem.

Could you get the traceback out of Django that's causing the 500 error and post 
it here?

Re: Patreon and Django-AllAuth Integration

[Andrew Stringfield]

I almost forgot.  I have checked my settings in Django and Patreon and the 
URL redirect matches for all that I can see.  I have an idea to try and use 
the testing framework to see what values I am passing to Patreon.

Re: Patreon and Django-AllAuth Integration

[Andrew Stringfield]

First, thank you for the response!  I want to use Patreon as a login 
account provider for my Patrons.  I have been playing around with the code 
some more.  This is what I have so far:

I created a view with the contents of:
def patreon(request):
request_string = 'http://patreon.com/oauth2/authorize'
request_string = request_string + '?response_type=code'
request_string = request_string + '_id=KEY_VARIABLE'
request_string = request_string + 
'_uri=http://website_name.com'
print(request_string)
response = requests.get(request_string)
print(response)
-
The print(response) produces: .  I looked up this error 
code and found: "403 Forbidden -- The requested is hidden for 
administrators only." at the URL of: https://docs.patreon.com/?python#errors
Please also note that the website_name.com is not currently online at this 
time.  If, I need to make it online, I can.

Patreon and Django-AllAuth Integration

[Andrew Stringfield]

Hello all,

I am trying to use Patreon's API Version 2 with Django 3.1.  I 
read: https://docs.patreon.com/#third-party-libraries and found that 
Patreon supported the django-allauth library.  I installed the library by 
following the instructions 
of: https://django-allauth.readthedocs.io/en/latest/installation.html.  I 
start up the default dev server and I go 
to http://127.0.0.1:8000/accounts/signup/ and fill out the form and hit 
submit.  I get the response of:
-
Page not found (404)Request Method:
GETRequest URL:
http://127.0.0.1:8000/accounts/profile/

Using the URLconf defined in mysite.urls, Django tried these URL patterns, 
in this order:

   1. admin/
   2. accounts/ signup/ [name='account_signup']
   3. accounts/ login/ [name='account_login']
   4. accounts/ logout/ [name='account_logout']
   5. accounts/ password/change/ [name='account_change_password']
   6. accounts/ password/set/ [name='account_set_password']
   7. accounts/ inactive/ [name='account_inactive']
   8. accounts/ email/ [name='account_email']
   9. accounts/ confirm-email/ [name='account_email_verification_sent']
   10. accounts/ ^confirm-email/(?P[-:\w]+)/$ 
   [name='account_confirm_email']
   11. accounts/ password/reset/ [name='account_reset_password']
   12. accounts/ password/reset/done/ [name='account_reset_password_done']
   13. accounts/ ^password/reset/key/(?P[0-9A-Za-z]+)-(?P.+)/$ 
   [name='account_reset_password_from_key']
   14. accounts/ password/reset/key/done/ 
   [name='account_reset_password_from_key_done']
   15. accounts/ social/
   16. accounts/ patreon/

The current path, accounts/profile/, didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django 
settings file. Change that to False, and Django will display a standard 404 
page.

-

I want to get data from Patreon, but it looks like I am just creating local 
user accounts in the database.  What am I doing wrong?

Shouldn't there be a library already for how to render your JS Frontend code into HTML and then insert your Django templates with jinja2 very easily?

[Andrew]

Hi all! I'm no frontend person, but I do help triage issues in 
djangorestframework-simplejwt. It's probably one of the most used 
authentication library for DRF users and most of all frontend framework 
devs of Django (i.e. React, Angular, Vue).

I've been getting lots of comments about issue #157 
<https://github.com/SimpleJWT/django-rest-framework-simplejwt/pull/157> not 
getting merged. I'm still not convinced that it should be merged at this 
point, but I'm wondering if there's a better way for these frontend 
framework JS devs to integrate with Django sessions.

Again, I'm no frontend JS person. In fact, I've never actually coded with 
React or any of these frameworks before (I just generally know enough how 
most integrate with Django). But looking into the techs themselves, 
shouldn't there be a way to render the HTML content on python manage.py 
runserver (or however way you're deploying with something like gunicorn), 
map out where you want to put your template tags (like you code with the JS 
tech and a library inserts where you want the tags or variables), and then 
voila... you can use the sessions middlewear?

If this hasn't been done, someone should make it happen... If enough 
attention comes by for a better idea, I'd love to help collaborate!

Re: Channels/Daphne offloading SSL Certs to AWS ELB fails to establish socket

[Andrew C.]

I’m about to create a PR (or not, not sure) with an AWS ALB setup for
cookiecutter django. The gist of it really is that there’s an article my
msaizar that has a good nginx configuration setup. Remove traefik and add
nginx. Your target group in AWS should have all machines registered on port
80 and you should be good to go. There’s a little more to what I’ve said,
but that’s the gist of it.

Re: 502 Bad Gateway nginx/1.14.0 (Ubuntu)

[Andrew C.]

What’s the HTTP status code? Does the nginx page even show anything? Try:

sudo systemctl stop nginx && sudo systemctl disable nginx && sudo systemctl
enable nginx && sudo systemctl start nginx

This command could also be in the wrong order... it’s been awhile.

It could be a symbolic link error. I don’t know. If you see some web page
with an error message like Internal Error 500 or the default nginx page,
let us know.

Re: In pycharm errror

[Andrew Fetting]

Sounds like you are on file too deep. manage.py should be in {project
name}\manage.py, not {project name}\{project name}\manage.py.
Hope that helps.

Re: How to Setup DjangoRestFrameWork with Mongo DB

[Andrew C.]

I highly recommend not using MongoDB. Sure, they can plaster a banner
saying “Google supports us” but many industry leaders have tried and failed
using it. It can’t store data that easily once you grow, making it unlikely
for usage in the future for employment by any startup or corporation and
for any realistic goal of scaling, too.

Use PostgreSQL’s NoSQL style with JSONB (JSONField) if you have to, and, if
you really need to index it, use a GIN index. Postgres is battle tested,
whereas Mongo is battle defeated.

I’d suggest you get to understand SQL vs. NoSQL first. Understand what’s
actually needed as an attribute and what isn’t. Most of the time, what you
think is non relational becomes relational. You can think partitioning and
sharding.

Sometimes you have to use NoSQL like with user profiles in which some
fields aren’t required. Use a JSONField, because I bet the REST of your
data is still relational.

Follow the general rules of why this works out. Not that people don’t use a
full NoSQL db like cassandra, but they use it for different use cases (like
throttling).

Re: AWS API or EC2 for chat?

[Andrew C.]

I’ve figured my original question out. API Gateway is usually paired with
Lambda. They scale easily, but I’m pretty much expecting 24/7 usage, which
Lambda isn’t the best option for(???). I use cookiecutter-django, so I’ll
be using ECS. Unfortunately, costs are sky high... If anyone’s able to help
me out any further regarding costs, please do so. Thanks!

I can provide one last hint. 1) understand what AnonymousUser model is. 2)
Look at

Re: write a new app

[Andrew C.]

If you want to avoid web frontend, then stick to mobile app development.
DRF as someone else mentioned helps. I recommend front end development
because they have guidelines and make thing easier to implement (iOS is
much much easier). You can’t make a usable app without doing both frontend
and backend.

As the last person said, do a project that helps your community. Don’t
think big, or a million dollar app idea, or money in general. Think
impactfulness on YOUR community only.

Backend code is not revolutionary. If you want business logic to be
revolutionary, then find a computer engineering job or code a huge
algorithm. Django and Flask are meant to be full-stack development
packages. When you get a job, you can think backend only, sure, but you’re
asking for a USABLE app; thus, my second paragraph still stands.

drop image in div and add path to db

[Andrew Fry]

Hi all... newbie here.

I have jQuery drag 'n drop working for a web app but cannot seem to figure 
out how to get the path of the dropped image uploaded to my db.sqlite3 
database.

What do I need to provide to get some help.

Thanks in advance.
-Andrew

Re: Channels, daphne, and asgiref, oh my!

[Andrew Godwin]

Hi Larry,

Your problem is the Python version - 3.5 is somewhat old (but most
importantly, was still a very rough release for asyncio) and isn't
supported by any current release of asgiref/channels for that reason. If
you are able to upgrade that, I very much recommend it.

Re: is there a WYSIWYG for Django

[Andrew C.]

Try Quill.js. If you google Quill.js and Quill.js Django, I believe
you'll find the Django package that goes along with that text editor.
Really, you only need the Quill.js code for your template. WYSIWYG is
just a user typing in HTML without realizing it. Just save the HTML
(because the rest is escaped while the user is typing).

It's also useful if you escape all instances of a script tag in case
someone inputs an unescaped . Your server wouldn't be
destroyed necessarily, but there could be some XSS that you want to
avoid.

Re: JSONField() ordering and removing latest

[Andrew C.]

Usually, something that has multiple versions could be in an autoincrement
field as the primary key. Then, in a JSONB field with GIN index (since
you’re using PostgreSQL), you would have a dict of each version, like this:

{
“1”: { # beginning of article 1
“versions”: {

“1”: {
“title”: “Blah1”,
“timestamp”: 172903740.0002782,
“image”: “http:test.de/test.jpg”,
“alt”: “Super text”
}, # end of version 1
“2”: {
“title”: “Blah1”,
“timestamp”: 1729375394.0002782,
“image”: “http:test.de/test.jpg”,
“alt”: “Super text blah”
}, # end of version 2
“3”: {
“title”: “Blah2”,
“timestamp”: 17290826300.0002782,
“image”: “http:test.de/test.jpg”,
“alt”: “Super text blah”
} # end of version 3

} # end of versions attribute/column
}, # end of article 1
“2”: {


“versions”: {

“1”: {
“title”: “Blah1”,
“timestamp”: 172903740.0002782,
“image”: “http:test.de/test.jpg”,
“alt”: “Super text”
}, # end of version 1
“2”: {
“title”: “Blah1”,
“timestamp”: 172903740.0002782,
“image”: “http:test.de/test.jpg”,
“alt”: “Super text blah”
} # end of version 2

} # end of article 2

} # end of queryset

So your primary key is a BigAutoField and your “versions” attribute/column
is a JSONField. IF YOU ARE FILTERING BASED ON ARTICLE TITLE, make sure you
put a GIN Index on that JSONField.

Re: DjangoEveryDay. My practice website!

[Andrew C.]

So for Django, you would need to do both frontend and backend. In my
opinion, your “behavior” would be to start in the frontend. How do you send
your message?

Someone in the backend for database modeling would be thinking ‘how do I
organize my cases?’ and THEN think ‘how do I present it?’

Re: DjangoEveryDay. My practice website!

[Andrew C.]

“How you think” signifies your mindset. CS is for problem solvers. And even
if you don’t have that mindset, with mass communication (so sociology??),
you need to decide which stack you need to do. A stack, for your case,
could be frontend. You being a mads communication expert in the frontend
would design the User Interface and User Experience (UI/UX) using HTML,
CSS, JavaScript, etc. in order to communicate your message clearly.

The way a mass communicator thinks is how can I spread my message beyond
the internet, correct? Even with a focus on the Internet world, something
coming to fruition for you would be to send a global message.

Re: open source advice needed

[Andrew C.]

Hi Kimberly,

I’ve taken a look at your preschool and school program, SNACS. Early in my
teen years, I helped set up [certain state in US] for an educational
bounce-back from zero funding to minimal, but the kid’s passions returned.
Django is a website framework, and I don’t think that’s what you're looking
for if you’re aiming for innovation. Or innovative learning.

Even with 300 students, I am skeptical of the model. I, for example, favor
large public education, but I do want to hear what SNACS is all about since
I would like to help implement some innovative learning strategies that I
didn’t find possible at a large scale.

But it depends on what your model is since your website never disclosed it.
Not to be negative, but it would be helpful to clear things up.

Best regards.

Re: open source advice needed

[Andrew C.]

Hi Kimberly,

Django is mostly for website development. If you can tell us a little bit
about your model and some plans, that would be great. I’d love to help
another Harvard student in their endeavors since many give up after
graduating grad school (especially those undergrads...). Again, let us know
what your model actually is.

Best regards

What is your major? Usually tying in what you know, how you behave, and
importantly how you think contributes to a certain type — or even workflow
or stack — of learning in CS.

Re: Correct Design: one app depending on another app

[Andrew C.]

I’m not sure what you mean by content management, so I’m gonna take a
guess: website builder like Weebly or Wix. You need a NoSQL database,
completely unstructured data. Kind of like a crime file drawer with folders
dedicated to each case and all its evidence. Some folders only have one
piece of evidence and others a whole lot, right?

By the looks of it, you’re making some revolutionary Weebly or Wix or
whatever with some custom features. If so, here’s what I’d recommend:

1) Read up on how jinja is developed. Jinja is the templating thing we use
in Django, for example: { if user.is_authenticated}
This will help you layout each individual website.

2) Use an unstructured database, like MongoDB or Cassandra. I almost always
tell people you should never have to use a NoSQL db, but in your case, it
might work. Take MongoDB’s document-based schema: each document belongs to
a single website. Within each document would be the site’s content using
keys as a way to input the key’s values on to the website (hopefully that
makes sense) using a jinja inspired template.

The thing I’m confused about is your media app. So I’m gonna guess again
and hopefully you can clear it up for me if need be. If not, still lemme
know.

Let’s say — I’m imagining a website builder like Wix and Weebly right now
btw — that a user drags some music container onto his/her website. The user
adds music and stuff via a different app? I don’t think that’s necessary
unless you code this part in C (for finding the files. Read on for what I
mean).

If you’re not using AWS with cookiecutter-django for deployment, I’d
recommend you go to The Eye (somewhere on Reddit and Discord or their
website) to figure out how to name these uploaded files or make some sort
of system to find these files quickly while keeping them private from other
users (by replacing uploaded file names with extremely long names. That’s
how Dropbox does it I believe).

The Eye is like an Archive team. They’re lovely and helpful people,
especially regarding data hoarding which you’re project might entail in...

I try my best to help completely new Django members with great ideas start
their journey or make that giant leap. So if this shit made no sense, don’t
feel frustrated when you could simply clarify some stuff for me. Good luck!

Re: Directly Accessing Dictionary Values

[Andrew Stringfield]

First, thank you for the reply Suraj!  I think that I misstated what I was 
really trying to do.  I am trying to access the dictionary values directly 
in the Template and not in the View.  I am trying to remove:

{% for question in unique_key_object %}
   {{ question.filename }}
   {% endfor %}

and just have:
{{ unique_key_object.filename }}

Directly Accessing Dictionary Values

[Andrew Stringfield]

Hello all,

 I am trying to access Dictionary values directly.  Here is my view:

def unique_key_query(request, unique_key):
unique_key_object = 
simpleformmodel.objects.all().filter(id=unique_key)
context = {'unique_key_object': unique_key_object}
return render(request, "bash_file_page.html", context)

Here is my template:
{% if unique_key_object %}
{% for question in unique_key_object %}
{{ question.filename }}
{% endfor %}
{% else %}
No data is available.
{% endif %}

I can access Dictionary values with a for loop, but I just do not want to 
do that.  How can I access the values directly?

Thank you.

Re: Channels 2 using asyncio run_in_executor

[Andrew Godwin]

It should be fine, but you will need to be careful - there's a lot of
side-effects with run_in_executor you should be aware of like the way
exceptions propagate (Django won't handle them right for you) and the
possibility of deadlock.

Re: Channels: launching a custom co-routine from SyncConsumer

[Andrew Godwin]

SyncConsumer isn't async - it runs inside a separate synchronous thread.
You'll need to get the event loop from the other thread and use
call_soon_threadsafe instead!

Re:

[Andrew C.]

I suppose in a view, you can write something along these lines:

import json
from os import path
from django.conf import settings

def index(request):
if request.method == ‘POST’:
 form = YourForm(request.POST)
 if form.is_valid():
 field1 = form.cleaned_data.get(‘field1_from_form’)
 # write your JSON here
 # Follow this tutorial to write your json:
https://stackabuse.com/reading-and-writing-json-to-a-file-in-python/
 # Instead of dumping your file into a txt like they did in the
first example, do this:
 with open(path.join(settings.MEDIA_ROOT, “ajsonfile.json”),
“w+”) as outfile:
   json.dump(data, outfile)
  return redirect(request.get_absolute_uri())
elif request.method == “GET”:
form = YourForm()
return render(request, “index.html”, {‘form’: form}


I forgot the import statement for the redirect

Re: How to build users tagging system in my comment textarea.

[Andrew C.]

You would probably need AJAX calls. I think there’s a package called
Django-autocompletelite which can help you with this. So, in your HTML, you
can use use AJAX to see when a user types the @ character with a single
letter and then show a box with some usernames with that.

Re: Getting AttributeError: module 'asyncio' has no attribute '_get_running_loop'

[Andrew Godwin]

Hi Rohit,

This is my fault - we made a change in the "asgiref" library that
inadvertently removed Python 3.5 support. Channels still needs to support
it (even though Django doesn't).

If you update to asgiref 3.1.4, which I've just released, that should fix
the issue.

Re: Internal Ranking System Application

[Andrew C.]

Np!

https://docs.djangoproject.com/en/2.2/ref/models/fields/#floatfield

Just refer to the docs. There’s FloatField and DecimalField for models.
When you show the numbers in views, just use python to round the numbers.
There are plenty of tutorials and SO (stackoverflow) questions that’ll
help. People on stack who like Django and want more rep points answer
Django tagged questions, so questions are quickly answered. Like matter of
minutes.

Yea, I think all those details are confusing me, but veerrry logical in
your mind since it’s your project. Here’re some things to keep in mind:

Queries: Use them efficiently. Using that one table, ContestScores, we can
find some scores for specific contests. We can write something like:

from .models import ContestScores

avar= ContestScores.objects.filter(contest=2)
thisvar = ContestScores.objects.filter(user=‘derek’)

Using this, we have a queryset. Any records/rows with contest ID 2 in the
ContestScores table will be in avar. In thisvar, any record that has a user
named derek will be stored.

When making a queryset needs to be ordered by some system (I think it was
descending scores), you can do this using the variables above:
avar.order_by(‘-scores’)

Signals: something I avoided for awhile, but got the hang of pretty
quickly. They have some cool little things like pre_save.

from .signals import my_func
pre_save.connect(my_func, sender=ContestScores)

#in signals.py in the apps directory

def my_func(sender, instance, **kwargs):
if instance.contest == 1:
print(‘hello, you should probably do something with this function’)
else:
 print(‘The contest for this record is Contest 1’)
if sender == ContestID:
print(‘the sender is a table, which in this case was ContestID’)
else:
print(‘hi’)


So, say someone created a new row in ContestScores. What’ll happen is,
before the object is saved in the database, it’ll go through that function
first. So if a user created a row setting the contest to be Contest 1, then
you should see “Hello, you should...” and “hi”

I imagine you could use signals for the Index(overall score. There’s
something in databases called indexes). When showing the ranks of
individuals, that’ll be done per request using the order_by method shown
above.

Regarding the semesters, I’d say just add another column to ContestScores
called semesters, then use the filter(semesters=1, user=derek) or
filter(semesters=1, contest=1).

The Django documentation is amazing, and can answer a lot of questions. I
also said to use Django REST API. You don’t need to use it, but the reason
I suggested it was because of its interface. Much smoother than the regular
Django admin, but does require a little bit more work. Of course in
production, you can disable it. I think of it as a neat debug toolbar.

Re: Internal Ranking System Application

[Andrew C.]

Gotcha. I’ll try my best to explain what you could try. And if this looks
sloppy, then I’ll make a public gist.

So, firstly, let’s set some things straight. A database is a collection of
tables. Models in Django represent one table with multiple columns. Tables
do not need to have the same columns. What you’ve given is one table and
appending lots of new attributes. That’s a non-relational database that I
advise you stay away from.

Here’s what I have in mind: there is a profile table. All users in this
table are in all contests.

We’re gonna first ignore the Profile model from that link. That’ll be the
thing that houses student’s grade. Django has its OWN Users model which the
Profile table extends from. Again, let’s ignore the Profile, for now. First
import the Django user model:

from django.contrib.auth.models import Users

Then,  based on what I’m imagining,  we’re going to make one table called
ContestID that can include Contest name(optional) and the main behemoth,
ContestScore:

import uuid

class ContestID(models.Model):
id = models.AutoField(primary_key=True)
name = models.CharField(max_length=True)

# You don’t have to have the id field since Django automatically enables it
if another attribute/column isn’t specified as primary key. I just wanted
to show everything

class ContestScores(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4,
editable=False)
contest = models.ForeignKey(ContestID, on_delete=models.CASCADE)
user = models.ForeignKey(User, on_delete=models.SET_NULL)
score = models.PositiveIntegerField(default=0)

Alr, here’s what’s goin’ on. We have multiple contests listed in ContestID.
If they don’t have names, you can delete the names column/line-of-code.

Then in the table ContestScores, we have an id field called UUIDField. In
regular relational databases, row ids are unique. In your spreadsheet, each
record/row was unique by an incrementing row number. For us, this might be
several gazillionbillionakfhwjbxin rows, so we wanna be safe with this
thing called Universally Unique Identifier.

The contest column is a foreign key. This means the that this row belongs
to Contest 1 or Contest 2, etc.

The score column is this user’s score based on a certain contest. The user
column specifies which user this record of scores belongs to.

So in its entirety, the Contest table would “read” like this: in Contest 1,
the user Derek received a score of 94. We can find this record at the id:
ajbi02-kebo... (it’s 32 chars long).

Ok, it looks pretty useless right now.

Now, let’s implement that Profile table:

class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE,
primary_key=True)
grade = models.PositiveSmallIntegerField()
index = models.PositiveIntegerField()

Before I move on, I just need to clarify something: what is the index? Is
it s/a, and is the index unique for each student. Is “a” the average of all
scores across all contests?

The ranking system, if I’m not mistaken, is ranking the players the ENTIRE
TIME. So the number one person should have the highest index, s/a.

I’m clear on what the index is utilized for: ranking. I’m just not so clear
on how the index is calculated.

If you decide you wanna learn this yourself, the best way is to learn what
a relational database is, like MySQL or PostgreSQL or SQLite. Just a small
visual explanation or just seeing a database like those will help you in
the long run.

But if you decide not to learn too much, because sometimes Django becomes a
lot too quickly, just clarify what the index is, and we’ll keep going.

Re: Can we create a Rest Api in Django which can able to communicate with multiple databases(Relational, Non relational) dynamically. If yes please recommend me a way to do that

[Andrew C.]

There really isn’t any point in doing that. 1) You should just use one of
the two. Django officially supports Postgres. 2) You’d want to keep your
users all jumbled in one database. If you have a foreign key to the
username field, and the db can’t find a specific user because it’s in the
other db, then what do you do then?

You wouldn’t need a REST api to do whatever your case is. Django supports
using multiple database; just check their doc with a google search. It’s
just a lot more business logic, and in my opinion, a lot more work and
inefficiency.

Try clearing your browser history and info. Should also test in Incognito
or Private browser so info is saved. I have a suspicion that your browser

Re: deploy to Heroku " collectstatic --noinput "

[Andrew C.]

Follow a tutorial.
1) Hide your secret key and everything secretive in an environment
variable. Or use Django-environ
2) Try python manage.py check —deploy
3) Debug is set to True... it should not be True if you’re publishing
(deploying)

Re: AutoField

[Andrew C.]

Probably because you have two AutoFields. You can’t have two in the same
model. Set this to eid=models.AutoField(primary_key=True)

This is because Django models automatically makes an id autofield primary
key if nothing else is set as pk.

Re: Run Daphne as non-root on low ports

[Andrew Godwin]

In this case "reference server" merely refers to it being the place where
new features and specs are implemented and tested first, rather than being
the best production-capable one. I would say uvicorn is probably the best
ASGI server out there right now for performance.

Re: Run Daphne as non-root on low ports

[Andrew Godwin]

Daphne does not have uid-changing built in, no - it's too simplistic for
that, unfortunately.

It's worth noting that systemd has this ability built in - it will listen
on sockets for you and bind the socket to an application as needed.
Otherwise, as the other poster noted, you can also use a reverse proxy to
terminate SSL, which is what Daphne is built assuming (the SSL support in
there is because it comes for free with Twisted, rather than being
specifically added).

Re: how handle high incoming data and sending throttled data to web sockets in django-channels

[Andrew Godwin]

You'll have to design your own consumption architecture if you want to
reliably handle 100 messages a second - since it's UDP, channels won't be
handling it natively so you'll need to terminate and process the UDP
yourself. I'd recommend either getting a UDP loadbalancer if you have
messages coming in from multiple sources, or do your own work queue if it's
a single source and you can't process them fast enough.

Re: channels and https

[Andrew Godwin]

You should use an ASGI server (uvicorn/daphne) with an SSL-terminating
server (e.g. nginx) in front of it and proxying to it. Django-sslserver is
a WSGI-based server and so can't support WebSockets.

Re: Django channels communication not asynchronous

[Andrew Godwin]

Channels request/response cycles must be natively non-blocking all the way
from the application code up through the server. If you even so much as
slightly block you're going to disrupt everything and maybe deadlock it,
which is why you need to be careful about when you call synchronous things.

If you don't want to deal with all of this, use the SyncConsumer variants
of everything and/or normal django views which will safely run stuff in
threads for you.

Re: Django channels communication not asynchronous

[Andrew Godwin]

You appear to have missed an "await" before "self.send" - could that be the
cause?

In general, the best thing to do if things seem to "block" is to set the
environment variable PYTHONASYNCIODEBUG=1 and Python will warn you if
anything blocks for too long and seems synchronous.

Re: Error when installing channels

[Andrew Godwin]

This is a general problem with installing compiled Python packages on
Windows. You'll need to install the compiler as outlined here:
https://wiki.python.org/moin/WindowsCompilers (or search for "python visual
c++ 14")

Re: Error of channels

[Andrew Godwin]

I've seen a lot of people have a similar error but I'm never sure what
causes it - that said, I generally advise them to check their Redis logs to
see if Redis is OK, as that could cause this?

Re: Channels: development issue with multiple daphne workers

[Andrew Godwin]

I'm not sure why you're getting the  _UnixSelectorEventLoop - that sounds
like a Twisted error you should search around for, and make sure you have
the right package versions.

--fd 0 should not be needed in that command line, since you're already
passing the UNIX socket, I don't remember why it's there.

I suggest you remove fd=0 and see if that then works with multiple
processes.

Re: difference between class based view and function based view

[Andrew Pinkham]

Django developers talk about three kinds of views:

- function views (FV)
- class-based views (CBV)
- generic class-based views (GCBV)

People do not make always make the difference between CBV and GCBV, which is 
unfortunate, as they serve different purposes (naming things is hard). When 
Andréas states earlier in this thread that "(CBV) use a lot of defaults for 
populating your templates, forms and views" that is not 100% precise. He means 
GCBV---which provide default (generic) behavior---not CBV.

Let's break it down. Below is an example of a FV.

from django.http import HttpResponse
from django.views.decorators.http import (
require_http_methods
)

# below is equivalent to require_safe decorator
@require_http_methods(["GET", "HEAD"])
def hello_world(request):
"""Demonstrate HTTP Request/Response"""
return HttpResponse("Hello World")

Below is an example of an equivalent CBV.
 
from django.http import HttpResponse
from django.views import View
 
   class HelloWorld(View):
 """Demonstrate HTTP Request/Response"""

def get(self, request):
"""Handle GET HTTP method"""
return HttpResponse("Hello World")

Formally, a CBV is any class that inherits from View. The only difference 
between the two views above is that the View class being inherited will give 
you automatic handling of HTTP OPTIONS.

Stated otherwise: FV and CBV are *equivalent* with the exception of automatic 
OPTIONS handling in CBV.

GCBV are simply CBV that have been given behavior. For example, instead of 
programming a view that shows a template with model data, you can instead 
inherit a DetailView, and customize it by setting class variables and by 
overriding methods. For more about that, I recommend looking at 
https://ccbv.co.uk .

So, when should you use a FV, CBV, or GCBV?

If you are building a view that a GCBV provides behavior for, save yourself 
time and use it! It's easy to add or slightly modify GCBV behavior, but 
difficult to remove behavior. The moment you're thinking about removing 
something a GCBV does, stick to a function or CBV.

So then, for choosing between FV or CBV: Do you need to handle multiple HTTP 
methods? Is there shared behavior between how the resource is handled by those 
HTTP methods? If yes, a CBV can help organize that logic and avoid duplicate 
code.

However, if you have a simple view (typically only one or two HTTP methods must 
be handled), then a FV will serve you fine (remember the view decorators!).

If you're not sure, start with a FV, and then switch to a CBV or GCBV if 
appropriate (as complexity goes up or when you realize you can use a GCBV).

Hope that helps,
Andrew

Re: Django with Channels 2.1.1 Error During WebSocket handshake 404

[Andrew Godwin]

You cannot use gunicorn to run WebSockets or other async code - you need an
ASGI server, like Daphne or uvicorn. Switch to one of those and it should
start working.

Re: Channels + django-tenants

[Andrew Godwin]

Hm, that's not sufficiently better than just supplying a new middleware to
be honest. The sort of hooks I prefer are where you can subclass and
improve what we ship with and give the user a new, non-fragile one, whereas
that just sounds like it's injecting a function in.

Honestly, given Channels is currently only one maintainer, any increase in
surface area is unlikely unless there's a very good reason. Channels' auth
stuff is just standard Django code + settings for the most part, so there's
already bits you can reuse to do most of the work.

Re: Channels + django-tenants

What sort of hook would you be imagining? The DB connection stuff is deep
inside Django itself, rather than in Channels, so I'm not sure what
sensible top-level thing we could provide that would make sense.

Re: Channels group_send hangs in extrenal process

[Andrew Godwin]

I've never tried using the async-to-sync stuff with multiprocessing -
first, I'd try removing that and see if it still works (just run from a
management command or script directly).

If it still fails, I'd suggest running a redis MONITOR to see if any
traffic makes it to Redis at all.

Re: Channels: Test case fails on async.sleep(X>0)

[Andrew Godwin]

Couple of points:

- Did you install pytest-django? That should help the settings thing.
- There's a default 1-second timeout on get_response; pass timeout=4 to it
and you should see that error go away.

We have a default timeout because otherwise we can't tell if an async app
has died/crashed and it'd hang forever!

Re: Channel: Migrate regular Django project to Channels2

[Andrew Godwin]

Channels doesn't take over at all unless you configure an async consumer.
To make sure it's working I'd recommend writing a single async consumer,
and running a test against that to ensure it works.

Re: Adding Channels to and Existing Django Application

I'm afraid I don't have an easy example to hand - maybe someone else does.
It sounds like you might have something odd in your settings, models.py, or
other files that load at startup.

Re: Channels: event loop and thread

[Andrew Godwin]

Your assumptions are correct. The only extra thing to be aware of is that
some Django interactions (like the Channels Auth middleware) need to do
database connections and thus have to launch into a subthread for that, but
that's also managed.

Re: Adding Channels to and Existing Django Application

[Andrew Godwin]

Hey,

You can just add channels to an existing Django project and only use it for
the bits you need it for - even down to running two different servers for
that project, one normal WSGI one and one ASGI one to let you do async
things.

You shouldn't migrate any existing code to channels - just add it and then
use it for the new bits you need it for, basically.

Re: How to subclass AsyncHttpConsumer for a GET request?

[Andrew Godwin]

Yup, that's the right way - subclass the async consumer class and then
write a handle method. You have to do your own post/get distinctions, like
in a Django view, but with the scope rather than the request.

Re: Channels -- a question about how ProtocolTypeRouter works

[Andrew Godwin]

I would instead think of the object that ends up there as a factory that
makes the final objects that end up per-scope. It's slightly confusing, I
will grant you, but in Python anything can make a new class instance, not
just a class constructor, which is what's happening here.

Re: Channels -- a question about how ProtocolTypeRouter works

[Andrew Godwin]

Hi Drew,

The return value is indeed an object, but if you look closely at it you'll
see it defines a __call__ method - meaning that when it's called as an ASGI
application, it then returns a further object to act inside the scope.

Re: Channels: about max message size

[Andrew Godwin]

Hmm, it's possible the 0.x series didn't have response streaming for files
so there'd be a limit, but I honestly can't remember, that was years ago.
There's really not much I can do other than recommending an upgrade to
something vaguely recent.

Also make sure Heroku is not cutting you off with a request timeout or
something.

That is correct. A view function/object is only called when a site visitor is 
routed to that callable by the URL configuration.

I'm not clear on your second condition, but you are probably interested in 
Celery for the first.

http://www.celeryproject.org/

Alternatively, some clouds provide the ability to run code on a regular basis. 
If your Django code is not closely coupled with cron job, you could use AWS 
Lambda.

https://docs.aws.amazon.com/lambda/latest/dg/with-scheduled-events.html

If it is tightly coupled and Celery is too powerful for your needs, you could 
use an AWS Lambda (or Azure Function, etc) to send a request to your Django API 
on a regular basis.

Re: Channels: rejecting web socket connections with a custom close code

[Andrew Godwin]

Hi Matt,

This is because the two ways of closing are different - closing before the
socket is open sends a HTTP error code (what browsers report for this is
different in terms of websocket errors), whereas closing once it is open
allows a websocket error to be used.

This is referenced in the spec at
https://asgi.readthedocs.io/en/latest/specs/www.html#websocket but somewhat
obliquely; I’ll try to make it a bit clearer.
