@jagged sedge Django has a very powerful CMS that is very easy to understand and use

Do I need any of that if I only run a blog without storing any information about my visitors?
kind steppe
If there is no identifiable data stored on any of your servers then no
If someone can grab some info from your blog and can trace it back to the user, and the user cannot remove it then I'm led to believe that's against GDPR
kind steppe
Oh it does?
So, under the section regarding a user being able to edit the information displayed, does that mean they are legally obliged to edit any information relating to them in the article?
meager anchor
i make programming posts xd
and the only user account is my own, in the django admin
i always think that regulations like this are great but not when i need to change my own stuff
kind steppe
Do you have comments?
As well as that, that article recommends to check your 3rd party companies are compliant with GDPR
meager anchor
I don't
kind steppe
That's fine then
brave mantle
Yeah I think you would be required to rectify, but like anything else, some common sense is required

brave mantle
IPs are not considered identifying
brave mantle
They aren't identifying, so that's a good thing really

@jagged sedge I personally like Wagtail... I think it's less monolithic (customizable) than the others, slick UI.. I like the modularity it presents

i don't plan on doing much web development with python, but should i look into it 'just in case'? if so, what should i use?
brave mantle
Flask is popular on this server, so is django
there's no end to python web frameworks tbh
tame viper
django is the one I've heard of the most
deep cave
web.py was my first. Django was my first real framework. Flask was the first I fell in love with.
I'm very much a believer in starting with Flask, though, and then moving to whichever one fits your style
Django is a fine framework but Flask keeps it simple. Much easier to start out with, hands down.
kind steppe
Flask allows you to clearly see what's going on without having to look through tons of files
deep cave
yeah

I had a look into Django's documentation about the User model from: django.contrib.auth.modelsI dont understand what the User model is meant for so can someone please explain it to me?
native tide
i mostly use User in views
to determine if the user is logged in, if they're an admin, etc.
auth also handles OOTB stuff like admin login
and you can generate modelforms for user logins
and account change forms, etc.
didn't know 2.0 is out :x
strange thorn
it has been for some time+
and it does soo much so much better
for example they finally allow flask style URLs
grand badge
true
the flask like urls is one of the best features
no more regular expressions bois!!

Great! Thanks. Well, I need some advice. I'm working on a role / permission system for my webapp, and I got an admin page where I want to be able to add roles and link specific permissions to them. I got this table setup https://i.imgur.com/YuqZyQ0.png and I can add roles and all that fine, but I was wondering if you guys had some advice on how I could update my database in the backend when I update a role with the checkboxes. My main roadblock is that the permissions (the titles at the top, such as read_members) are also just entries in my Permission table in my database

If i have a website running on pythonanywhere, will it have SSL? I read something on pythonanywhere, it said that websites with the pythonanywhere domain name already has HTTPS.

@sterile peak if you do use gunicorn (or at the very least set up logging for the flask server) you should be able to figure out why it dies.
that's basically the next step for you
without that information, nobody can help you
sterile peak
roger that, thanks
deep cave
I mean, it's a python process, it'll leave a traceback
sterile peak
it could be load related i feel, server has 2gb of ram and at peak had 10 odd people accessing at once
deep cave
if you're just listening
sterile peak
but it seems unlikely
because the discord bot running in parallel works fine all the time
deep cave
yeah. my guess is there's just a simple error somewhere that logging would make clear
sterile peak
the code doesn't return any errors, have tried that way too much
deep cave
but I mean you absolutely need logging either way.
sterile peak
yes, that's true
deep cave
running any kind of webservice without it, it's just irresponsible.
so fix that first
and see what it says when it dies.
if it says nothing, we'll work with that
maybe it says nothing
who knows
sterile peak
okay for logging, should i run the logging module in python or use gunicorn for it?
deep cave
but most likely there'll be a traceback
that's your call but it wouldn't hurt to use a real webserver instead of trying to use the flask thing even though flask expressly tells you not to
brave mantle
Use gunicorn for logging
sterile peak
i've spoken to someone who knows way more than i do last night and they think it has to do with API requests failing/timing out
brave mantle
It doesn't hurt to use the logging module in addition though
To just format your output
deep cave
both is pretty common, yep.
deep cave
I mean gunicorn will tell you if it stops serving the site for any reason
but your site itself should also log things
sterile peak
that's actually pretty damn useful
deep cave
gunicorn won't tell you if that one api call is fucking up, for example
that's up to your site to log info about
see how there's a bit of separation there?
sterile peak
yeah that makes sense actually
just for a bit of extra context the site is up at the moment and it runs fine - it's when multiple people use it at the same time or in quick succession that it fails
brave mantle
Are you just not using gunicorn?
sterile peak
not yet
deep cave
he's just using the flask debug server
sterile peak
yeah
brave mantle
I mean, if you only have one flask server then yeah that'll break
sterile peak
that'll be it then i think
brave mantle
You need to have a bunch of workers because there's no concurrency by default in flask
That's why we use stuff like gunicorn
sterile peak
it would explain the lack of errors or anything in the console too
brave mantle
Well it wouldn't crash but the requests will get backed up
sterile peak
i believe so too
brave mantle
This is about PHP, but.. Three thousand people line up on your apartment's welcome mat and demand to be shot in their feet. One by one, you oblige them, but halfway through, the http connection times out and the crowd lynches you.

just ask if anything else comes up :)
sterile peak
i'm gonna look into setting up gunicorn today and hopefully that'll be it
thanks ever so much 
sterile peak
cheers!
deep cave
it's pretty easy to set up, gunicorn
it's one of the easier ones.
but if you run into trouble with it just ask in #414737889352744971 and we'll help you out :)

basic (but probably hard) question
what would be the most effective way for anyone that doesnt know about #aaa or anything related to it find out or learn about that?
for example,
- what it looks like
- what it does
- why it's 3 letter
- why it has a # before it
- why the letter are the same and repeating
- what exactly the saturation of that color is
- what exactly is the lightness or darkness of that color
- anything else about what in the world that means
aka: how would anyone in this universe that doesnt know about anything related to this get from that point to learning about #aaa ?
that is the question, and best answer/solution is needed

brave mantle
well first of all you get all the documents
proven jungle
done ^^
brave mantle
and then you pass them to your html template
and then your html template generates a table or something
proven jungle
i tried as i do with discord.py
brave mantle
if you're not using a templating language
proven jungle
def ideas_review():
ideas_list = []
if request.method == 'POST':
database = mongo.db.ideas

return render_template('admin.html')
you've already lost
yeah, see, newlines don't work
because you're working with HTML
proven jungle
i should do <br>
proven jungle
but it would print <br>
i know how to do a table
but no idea on how to do it in this situation
brave mantle
I mean you can just pass the cursor to the template for a start
the actual table generation should be done in the template
which I'm assuming is a jinja template
proven jungle
<body>
<ul>
<li><a href="/index">Home</a></li>
<li><a href="/subscribe">Subscribe</a></li>
<li><a href="/ideas">Ideas</a></li>
<li style="float: right;"><a href="/admin">Admin</a></li>
</ul>
<br><br>
<form method="POST" action="/ideas_review">
<h3>Ideas Review</h3>
<br>
<p>{{ideas}}</p>
</form>
<form method="POST" action="/emails_lookup">
<h3>Lookup Emails</h3>
<br>
<input type="submit" value="Submit">
</form>
</body>
well that looks like jinja
jinja can do loops and all of that stuff
so you'd start with your table element, your first <tr> with your heafings
then loop over the documents, generating a <tr> for each
and then close your <table>
brave mantle
OK, so you sent a bad request
brave mantle
Check the logs
proven jungle
i've created 2 "def"'s
instead of only one
and it is probably going to check this stuff in the first one
and not in the second one (the right def)

You shouldn't be providing errors that verbose
proven jungle
¯_(ツ)_/¯
but what about my problem?
i have 2 defs and it probably goes to the first one
thing that shouldn't happen
proven jungle
yes
brave mantle
Take a look at the whole MethodView thing
You might find that a bit easier to work with
proven jungle
i can have a class with many def's
brave mantle
MethodViews are one class per route
And each function in the class corresponds to an HTTP method
proven jungle
One class, yeah
brave mantle
so like, def get():
proven jungle
But not one "def"
brave mantle
You can't have more than one def per route
I'm pretty sure that's undefined behaviour
proven jungle
I did something better
I mean, i like it as well
Now i need to create the table
@brave mantle sorry for the tag
the page works
but it doesn't show the documents
brave mantle
well, are you inserting them into the page in the template?
Are there actually documents in the table?
brave mantle
you're progressing, I guess
proven jungle
i am 
how do i create newlines?
wait
i can do it with the table
but how?
for document in cursor:
ideas_list.insert(1, "ID: {}Username: {}Email: {}Idea: {}".format(document["_id"], document["username"], document["email"], document["idea"]))
return render_template('admin_ideas.html', ideas="<br>".join(ideas_list))
cause if i do that, it prints documents separated by commas
brave mantle
I dunno why you're trying to do formatting in your class
don't do that shit
do it in the template
proven jungle
ok but how?
brave mantle
I told you how
Generate a table using a loop
If you don't know how to do it, read the jinja docs

====== any chrome users here or another day ? =====================
on chrome://settings/fonts , you can change the font 'type' (like how it looks)
- but i dont think it changes it on some sites
how does this chrome font thing work basically? (im guessing there's may not be any links that explains it) does it replace fonts on all sites?
or does the site decide what font to use?
cyan pilot
Have you looked up info about this online yet?
kind steppe
@fiery kestrel No, it won't do that, it won't make sense
websites decide what fonts they will display
At least it doesn't seem like that's how it should work
It could change the font when a site has not declared a specific font
ahh this looks like it:
The font settings that you set in the options are used when the following is true:
The web page has not specified a font of its own.
The web page has properly declared the language of the content.
browsers have a default style sheet
that's the font that is used when the site doesn't define the font-family style

why not?
report = namespace.model('Report', {

Because it doesn't have a refresolver

But the error message is clear enough
Namespace object has no refresolver

Hello guys, I am having a little problem w/ GeoDjango on Windows (W10x64), I get this error when running any manage.py command (e.g. python manage.py test or python manage.py makemigrations):

Any idea? 😅

Sup! I have a little problem with Flask. I use Azure Webapp + MySQL (free level with Dreamspark) for my app in Python. On local my app is working great but, on azure, when I login I have:
Internal Server Error The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
I can see the login screen, but the app crash when I submit.

in Django, is it possible to ignore a database from testing? i don't even use this one but django tries to create a test database regardless, which doesn't work because the Postgres user is read-only. here's the db setting:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
},
'stats': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': os.getenv('PGSQL_DBNAME'),
'HOST': os.getenv('PGSQL_HOST'),
'USER': os.getenv('PGSQL_USER'),
'PASSWORD': os.getenv('PGSQL_PASSWORD')
}
}
and the exception:
$ python manage.py test
Creating test database for alias 'default'...
Creating test database for alias 'stats'...
/Users/Johannes/.local/share/virtualenvs/programming-site-WuXY6p7p/lib/python3.6/site-packages/django/db/backends/postgresql/base.py:259: RuntimeWarning: Normally Django will use a connection to the 'postgres' database to avoid running initialization queries against the production database when it's not needed (for example, when running tests). Django was unable to create a connection to the 'postgres' database and will use the default database instead.
RuntimeWarning
Got an error creating the test database: permission denied to create database
now this looks like it runs the tests, but it doesn't 🤔
oh I have an idea
brave mantle
You should be testing on a separate database dude
one that you have write access to
meager anchor
sorry, i should've mentioned, the database stats is not used in any tests, and django is not supposed to ever write to that database anyways. it's from another app
apparently there's no simple solution on the django end, gonna look into getting write access
kind steppe
@meager anchor are you writing an api for programmings stats database lol
kind steppe
Oh fairs
meager anchor
oh man django is SO GOOD
i initially used a generic View
so I had methods get, post, etc. instead of checking for the request type myself and handling all possible cases
now I read a little bit more, and essentially what my view does is render a form for creating something
.... voila
now the code is 90% sending the webhook

@meager anchor im getting this error when i try to create a superuser on the Programming server site:
django.db.utils.IntegrityError: NOT NULL constraint failed: home_user.discriminator
right
i‘m an idiot
and modified the user model
i think you can circumvent this by manually creating the social application for discord through the database, but that‘s a really great example as to why that was not a good idea
i need to figure out a better way to attach a discord user to django
grand badge
sooooo, umm i cant create superuser??
grand badge
i did migrate
also, when i run the server, it says 'Illegal instruction: 4' and doesnt run
meager anchor
no it's not a "simple not migrated app error"
meager anchor
i modified the user model to add a couple of discord-related things
you don't have to create superuser
sqlite3 db.sqlite3, insert the social app and modify the domain of the site with ID 1, then oauth should be set up and you can log in through the site
grand badge
what?
meager anchor
you can't create a superuser because i have a custom user model that django doesnt support natively
so you need to insert the relevant values without the admin
brittle copper
I just said it looks like that dude, chill; integrity errors are usually because there is no field in database; at least the ones I had when I was doing my website
grand badge
what values are you talking about and where should i add those values?
meager anchor
just use sqlite3 db.sqlite3, ```sql
INSERT INTO socialaccount_socialapp VALUES ("discord", "Discord OAuth", your-discord-app-id, your-discord-app-token);
also make sure you set the domain for django_sites correct
if you run SELECT * FROM django_sites; it will most likely start with 1|example.com|example.com
you wanna set that to localhost or whatever you're entering into the address bar to view your local django dev server
UPDATE TABLE django_site SET domain = "127.0.0.1:8000";
is mine
grand badge
what does it mean by the discord app id?
meager anchor
you need to create an application on the discord my apps thing
and then grab the id / token from that
grand badge
okay
meager anchor
grand badge
so i make a new app right?
meager anchor
ye
grand badge
i made a bot and put the token in but it doesnt work
meager anchor
no it's not a bot
grand badge
did u mean app-secret?
meager anchor
just the Client ID and Client Secret at the top of the page
grand badge
oh okay
meager anchor
the catch is, being the smart guy i am, i hardcoded our guild ID for pretty much every permission check
so you won‘t be able to do anything on the site unless you set your superuser status in the database
kind steppe
smart move my lad
grand badge
i tried putting the client id and client secret in, but it this is what happened: Error: no such column: <client_secret>
meager anchor
how did you insert
grand badge
INSERT INTO socialaccount_socialapp VALUES ("discord", "Discord OAuth", your-discord-app-id, your-discord-app-secret);
anything wrong with that?
grand badge
i did
meager anchor
in quotes?
grand badge
oh shit
meager anchor
🤨
grand badge
Error: table socialaccount_socialapp has 6 columns but 4 values were supplied
Seeningly, I probably forgot something
the first value is ID
run .schema and check the cols
maybe the site ID (1)?
grand badge
CREATE TABLE IF NOT EXISTS "socialaccount_socialapp" ("id" integer NOT NULL PRIMARY KEY AUTOINCREMENT, "provider" varchar(30) NOT NULL, "name" varchar(40) NOT NULL, "client_id" varchar(191) NOT NULL, "key" varchar(191) NOT NULL, "secret" varchar(191) NOT NULL);
i think im missing id and key
@meager anchor what is "key" meant to be?
meager anchor
empty
i forgot that column
I believe it‘s supposed to be empty, i can‘t check right now
grand badge
nice, i think it works
grand badge
okay, im going to create superuser
meager anchor
you cant
meager anchor
because i use a custom user model that it doesnt support
grand badge
oOoO
meager anchor
yeah its a bit dumb 😛
but it works on its own, without some other bot or something lul
grand badge
when i run the server, this happens:
System check identified some issues:
WARNINGS:
stats.AuditLogChanges.audit_entry: (fields.W342) Setting unique=True on a ForeignKey has the same effect as using a OneToOneField.
HINT: ForeignKey(unique=True) is usually better served by a OneToOneField.

wait
i'm pretty sure you need to checkout a commit without the pgsql database
grand badge
i thought it used sqlite
meager anchor
not only
try git checkout 8f8c56f95da8a1dc993eb177722b926eb17b26fd
that was the last commit before pgsql db integration
meager anchor
👍
grand badge
no module named stats? apparently
meager anchor
where do you get that error?
this seems to be absolute hell to set up
i should fix that
grand badge
the urls for guides, line 13
i will try fix it
sorry not urls.py
it works!!
fixed it
grand badge
where is the login page?
meager anchor
see the $(YOUR_USER) in the top left?
grand badge
yep
meager anchor
click
grand badge
DoesNotExist at /accounts/discord/login/
SocialApp matching query does not exist.
got that error
meager anchor
alright, go into the database, and query SELECT * FROM django_site;
does the right column specify example.com?
grand badge
do u mean http://127.0.0.1:8000/ ?
meager anchor
then:
UPDATE django_site SET domain="127.0.0.1:8000";
updated
grand badge
no
meager anchor
then you need to insert that
for me it was sql INSERT INTO socialaccount_socialapp_sites VALUES (1, 1, 1);
meager anchor
and you have the socialapp set in socialaccount_socialapp?
grand badge
?
meager anchor
the one i gave you at the start, with the app id and app token
grand badge
i think so
meager anchor
query it to be sure
grand badge
im not too familiar with SQL
meager anchor
SELECT * FROM socialaccount_socialapp;
grand badge
yes i have the things i entered earlier on
meager anchor
ah, yes
my favourite error code
the one that was 100% clear about what didn't work and helped me save countless hours debugging
grand badge
okay so its fine??
meager anchor
just to be sure: SELECT * FROM socialaccount_socialapp returns something along the lines of
1|discord|Discord OAuth|some id||<token>```i wish (it isnt)
grand badge
yes, it gives me the token and id stuff
meager anchor
the || before the token
grand badge
yep
meager anchor
are you sure these are app credentials and not for a bot?
meager anchor
did you convert the app to a bot ?
grand badge
no
meager anchor
did you specify a redirect URL, namely this one, in my apps?
meager anchor
http://127.0.0.1:8000/accounts/discord/login/callback/ here it is again, for copypasta convenience
yes
You must specify at least one URI for authentication to work. If you pass a URI in an OAuth request, it must exactly match one of the URIs you enter here.
grand badge
ah yes
meager anchor
save changes, retry
meager anchor
click authorize, and you will realize the sad truth: that nothing really works, because i hardcoded the server ID, and the permissions setup i use is absolute cancer
but yeah
why did you set this up, anyways? 🤔
grand badge
set the website stuff to work on my machine?
meager anchor
oh okay
grand badge
like why am i contrib ing?
idk, im just bored and want to work on a collaborative project
meager anchor
oh cool!
i should, uh, hm, how do I make this usable by other people
the statbot integration kinda makes it hard
meager anchor
which?
grand badge
at the start when i was trying to run the server, i module that does not exist got in the way
you removed the stats app
meager anchor
i think that was because you checked out an old commit
but I'm not sure
if its a specific commit thats broken i can look into it and rebase
grand badge
should i push to the repo i forked?
grand badge
i commented out from stats.models import Users as DiscordUser
meager anchor
which commit hash was that?
grand badge
idk
meager anchor
are you in detached head?
grand badge
i think so
meager anchor
if you run git status, I think it should show you which commit you're at
if you have a detached head
grand badge
guides/views.py
meager anchor
lets hope I didn't just break the entire git history
looks ok
i think I fixed it, thanks
grand badge
so theres no need for me to push?
meager anchor
nah
grand badge
mkay
meager anchor
I'd have to rebase that commit either way
grand badge
okay
grand badge
say i come up with an idea for the site, how will i work on it without having a superuser?
meager anchor
that's a good question that i didn't have to ask myself yet
right now the superuser thing is integrated with discord: if you're an admin on our guild, you're a superuser
which is bad
grand badge
hmm
meager anchor
i'm currently fixing up the user model so I check that stuff via statbot instead of messing with the model
grand badge
grand badge
awwww
meager anchor
gimme a sec
if you really really really want to contribute, you'll need an instance of https://github.com/strinking/statbot
grand badge
what does it do?
meager anchor
it's the thing that drives our server statistics
grand badge
oh
meager anchor
we plan to add this to the django site
the inspectdb command, I think that was it, is amazing
i had to write very little code because django automagically generated almost all models
meager anchor
you need to run that somewhere so that the django app can talk to it
grand badge
okay
mental chasm
Can't he just get an account to the database
meager anchor
i doubt that
mental chasm
What's the point in it then
meager anchor
in what
mental chasm
In storing the data
meager anchor
for using it in statistics like on ddd or other things, such as the permission system i'm now using
mental chasm
But I meant what's the point if it's locked down for like 3 people to use
Handing out a read only user would be fine
meager anchor
whats the point of a bank vault if it's locked down for like 3 people to use
mental chasm
That's a very, very, very bad comparison
mental chasm
Like what lol
meager anchor
anyways, i don't maintain the pgsql instance, striking does. and striking knows what he's doing.
mental chasm
That is showing me the table, not an example of "sensitive data"
And actually if I remember correctly he was the one saying to hand out read only users the last time I asked about an API
meager anchor
i don't know the exact reasons.
mental chasm
...?
meager anchor
here's an example of sensitive data
meager anchor
what's the point of discussing this, anyways?
striking and ais set this up and they're well-respected people, they know what they're doing
mental chasm
I'm not saying they are wrong
And if you read what I said above, you'll realise that lol

but my program works using data[-1]... and it sees no "last message" when I tried it this way..
Am I looking for a JSON server? Or should I be reading the JS docs on how to print some lines of text, mimicing json to have a faux type json server?

Im trying to get the detail view of an object to show in a template, but when im in the ListView, i get this error:
NoReverseMatch at /tutorials/
Reverse for 'detail' with no arguments not found. 1 pattern(s) tried: ['tutorials\\/(?P<slug>[^/]+)\\/$']
I am new to Django CBV's and tried improvising ways to get it to work.
# views.py
from django.views.generic import ListView
from django.views.generic import DetailView
from django.shortcuts import get_object_or_404
from .models import Tutorial
class TutorialList(ListView):
model = Tutorial
context_object_name = "tutorials"
tutorials = Tutorial.objects.all()
class TutorialDetail(DetailView):
model = Tutorial
context_object_name = 'tutorial'
def get_context_data(self, slug, **kwargs):
context = super().get_context_data(**kwargs)
tutorial = get_object_or_404(Tutorial, slug=slug)
context['slug'] = tutorial.slug
return context
# urls.py
from django.urls import path
from . import views
app_name = 'tutorials'
urlpatterns = [
path('', views.TutorialList.as_view(), name='list'),
path('<str:slug>/', views.TutorialDetail.as_view(), name='detail'),
]
<--tutorial_list.html--!>
{% extends "layout.html" %}
{% block title %}Tutorials{% endblock %}
{% block content %}
{% for tutorial in tutorials %}
<h2><a href="{% url 'tutorials:detail' %}">{{ tutorial.name }}</a></h2>
<h3>{{ tutorial.subject }}</h3>
<p>{{ tutorial.description|truncatewords:5 }}</p>
<hr>
{% endfor %}
{% endblock %}
TutorialDetail expects the slug as its argument
see the path: path('<str:slug>/', views.TutorialDetail.as_view(), name='detail')
grand badge
yes
meager anchor
you may be looking for {% url 'tutorials:detail' tutorial.slug %} instead
that's how I use it at least
meager anchor
np
seeing as you dont use it in the template you can probably also remove py def get_context_data(self, slug, **kwargs): context = super().get_context_data(**kwargs) tutorial = get_object_or_404(Tutorial, slug=slug) context['slug'] = tutorial.slug return context
then
grand badge
Im getting this error when i click on one of the links:
TypeError at /tutorials/test-tutorial-creation/
get_context_data() missing 1 required positional argument: 'slug'
then how will i get slug in get_object_or_404()?
meager anchor
no
although, if you pass the slug of the tutorial named as slug, you need to specify pk_url_kwarg = 'slug' in DetailView
because it expects pk normally
or you change path('<str:slug>/'... to path('<str:pk>/'... in urls.py
grand badge
in views.py, should it be like this?:
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['slug'] = self.model.slug
return context
well, if you can access the slug as tutorial.slug anyways, why pass it to the context like that in the first place?
