state is a charfield with a list of tuples for the choices ?
#web-development
bleak bobcat
dense slate
I guess this is countries, but state works the same way:
COUNTRIES = ( ('AF', _('Afghanistan')), ('AG', _('Antigua & Barbuda')), ('AI', _('Anguilla')), ('AL', _('Albania')), ('AM', _('Armenia')),
the value in the DB is one of those tuples.
bleak bobcat
{{ record.get_state_display }} should work
dense slate
It just removes the entry.
{{record.country}} gives me 'AL', inthe case of Albania being the entry.
bleak bobcat
And {{ record.get_country_display }} gives you nothing ?
dense slate
Right
bleak bobcat
And you have translations for all those countries, no empty translation ?
dense slate
Each country has a full-name associated with it, if that's what you mean?
bleak bobcat
the _() suggests it's a i18n variable
dense slate
Honestly I took the list from somewhere, so I don't know what the _() is accomplishing.
bleak bobcat
Ah. If you're fine with english only names for your countries remove the _()
dense slate
Will that affect current entries?
dense slate
Ah, well, states looks like this:
STATES = ( ("Alabama","Alabama"), ("Alaska","Alaska"), ("Arizona","Arizona"),
and I have the same problem, so I don't think that's it.
bleak bobcat
Alright. What do your state & country fields looks like in your model ?
dense slate
Ah...
Ok, so it's being saved into the field as country = models.CharField(max_length=100, default="", blank=False) rather than the entire thing
bleak bobcat
You need a choices=STATES (or COUNTRIES) on this CharField so django knows what the values can be
Without this django can't restrict the field to those values and the get_***_display() will not work

Does anyone have a decent production ready Django Docker setup I can look at?
preferably a relatively simple one with no bells or whistles
dense slate
Right gotcha, ok let me play with it. Need to update some things.
lethal orbit
preferably a relatively simple one with no bells or whistles
@rigid laurel simple? no. Production-ready? yes. https://gitlab.com/sports-prediction/sports-prediction/
This uses gitlab-ci to build images on push, with a manual deploy.
rigid laurel
Those two are somewhat oxymoronic I guess
lethal orbit
Feel free to look at it and ask questions.
rigid laurel
I think that setup is a bit too complex compared to what I'm going for. I literally want one container which is the Django app (and one in dev only for the database) - that many compose files is just too scary
thanks though
lethal orbit
This is much simpler. But we never made a production build lol
Really, if you rename the .dev.yml to .yml, and change the Dockerfile to start gunicorn instead of runserver, this probably isn't far off from what you need.
dense slate
Got it @bleak bobcat Thanks!
rigid laurel
This simpler example is helpful yeah - thanks @lethal orbit. I'm fine with writing code, but god do I hate making it run
lethal orbit
Learning devops is fun
distant trout
isnt it hard tho
distant trout
what is devops again exactly
distant trout
devops is like the cloud hosting right?
lethal orbit
More like automated testing, automated (repeatable) deployments... better integration between writing the code and deploying it.
distant trout

zealous siren
@heady ore not sure. We use CosmosDB extensively in SQL API so I know itโs fast. Open a ticket if you want and think itโs CosmosDB side.
heady ore
@zealous siren i believe it is convenient, must be sth wrong on my code. MS support engineer said it might due to the initialising the connection. for my understanding, i might need to avoid calling the client instance too many times. so still checking what cause this issue so far
btw, he mentioned the partition key as well, but i don't think it's the key point in my case. since i only have 15 data in one collection for testing
still need more background knowledge, my first year in backend๐คฃ
zealous siren
Outlier, I wouldn't use MongoDB API UNLESS you are trying to convert
SQL API is best API
heady ore
because the project will have many changes. mongodb will be a better choice
quick cargo
i wouldnt say mongo isnt the best for changing things
If you want to change the collection names or anything reliably you have to delete the collection and re fill it
native tide
@lament kraken U can learn htm;,css,js from clever programming or freecodeCamp.org
mellow tide
yeah, i literally use mongo for nothing that i deem important
native tide
i wouldnt say mongo is the best for changing things
@quick cargo
Why?
lament kraken
SQL is best
wind condor
it has name of them and teaches what they teach
some teach css html and js
it has a list of tech channels
lament kraken
I will go with @native tide suggestions, thanks bro
native tide
html,css = easy as hell and js = yeah alright
wind condor
@native tide what do you mean why
native tide
I already showed him the path of a web developer
wind condor
i was trying to help...
native tide
yeah good
wind condor
bruh
wind condor
:/
quick cargo
Also Yall are comparing a Single NoSQL database to an Entire query language and an entire scope of databases
native tide
Nah we just chilling
quick cargo
just because mongoDB isnt the best doesnt mean that NoSQL in general is the worst lol
mellow tide
lol @ mango though ... a legit mango would be a better data store than mongo is ๐
native tide
Lol
mellow tide
as far as NoSQL goes, i actually really like Cassandra. and on that same front kind of, BadgerDB
native tide
The best books to learn Django๐
mellow tide
Packt does have a lot of great stuff
native tide
Yes that's right
heady ore
the response seems getting far from my question ๐คฃ
native tide
Django is mad thing because of the file structure i couldn't even sleep the day I learned Django
legit i was on the floor and crying
mellow tide
I tend to like the NoStarchPress stuff better though. No Django stuff though
native tide
And the next day i was about to quit programming because of django file structure which made me wonder why i'm living in this earth
this is not even a funny guys legit i'm dead honest
And the next day i was about to quit programming because of django file structure which made me wonder why i'm living in this earth
@native tide
I believe we live to be in pain and to learn from pain๐
But everything is good now because of flask yeh man if i start talking about flask then we would be on earth for 1000 years
mellow tide
Django has it's place, just like Rails, but yeah, it's not a silver bullet lol
I'm testing the waters with Blazor right now actually
it reminds me of Vue/React ... except is C# on WASM lol
quick cargo
was tempted to play with Rust and WASM
mellow tide
i've not found a good library yet that doesn't make you do all of the bindings yourself, which is fine, but not something i would advertise to novices lol
there are a few that are coming up, but not really ready yet
native tide
Just did a search and I might try out seed
quick cargo
atm i got bigger issues todo with like debugging why the server freezes up when a high load comes in ๐ฉ

looks like you have another instance of it running already @tacit anvil
tacit anvil
i dont have it open but i will restart to see if that helps
mellow tide
or you installed something that ate port 5000
mellow tide
not sure what OS you are using, but it's possible to send those things to the background pretty easily
mellow tide
yeah, if you accidently add a & at the end of any script, it goes to the background ๐
you could do a sudo netstat -tulpn if it happens again to see what is using your port

proper kraken
cant get <img src="kebab.png" width="50px" /> working, tried with images/kebab.png but it just displays as that weird default pcture (when the pic in question isnt found)

@tacit anvil Are u trying to make a chat app using socket programming and flask?
tacit anvil
no
im trying to make a website using html
and python and the back end
using flask
tacit anvil
yes
tacit anvil
idk what that is
native tide
Don't worry I'll explain u what is bootstrap
Bootstrap is the most popular CSS Framework for developing responsive and mobile-first websites
ok
quick cargo
definitely not the best framework tho :P
native tide
@quick cargo Yep
i'm going to learn JS now, help me
give me some good resourves
@native tide U learned python first?
um........... yes
ok one advice
Js syntax might be hard ok and don't give up continue learning js
but I just learned python basics and that's it
I will continue python later
ok
Js syntax might be hard ok and don't give up continue learning js
thanks
Gl
it seems so
I finished the first lesson on FCC.
but I didn'tt understand much.
@native tide Btw every high level programming language like ,python,javascript,c++ covers same concept so don't be worry about while looop or for loop if statement because it's all just same
yep
but it has something like do......while
also python was much much easier than JS.
yes python is easier than js
Don't stop python aswell
ohk
how?
Everything must be in balances
i mean "don't stop python aswell" just do the basics to remember
that it
like?
basics?
I already know them.
nvm gl
but I didn't made any projects in python
I only made password checker, img to pdf, dictionary, etc
back to my question : "give me some good resources"
back to my question : "give me some good resources"
@native tide
To learn python?
JS

@native tide
1.Sololearn
2.any book
- Freecodecamp
I already know about FCC and sololearn......... thanku
but which book should I follow?
oh wait
I just found this.
@native tide
ohk
thanks
ohk
found it's pdf
Yes
contains questions at the end of each lesson the questions are in a link at the bottom of the page, If you don't open the link use VPN

modest scaffold
where is the most simple and cost effective place to deploy a django project
mellow tide
netlify or heroku probably
modest scaffold
I've looked at heroku but that has issues with user uploaded images and ive also look as aws lightsail and elastic beanstalk look complicated af
mellow tide
lightsail isn't hard
beanstalk is
if you are containerized, google cloud run might work for you
mellow tide
using docker, but i am going to assume that is not the case given you didn't know the terminology lol
modest scaffold
nope not using docker
mellow tide
docker makes deployments cheap and easy (usually) ... it's worth looking in to, but otherwise, take a look at netlify
modest scaffold
what does it do
mellow tide
i honestly don't suggest AWS for anyone unless they themselves want it
modest scaffold
yeah aws just looks like pain
mellow tide
it's not hard, but i just hate how they run their business lol
and their API is crap
mellow tide
yeah, netlify is a nice one-stop-shop for web apps
modest scaffold
i cant really find anything for django on netlify
this article has the word once
mellow tide
ah, nevermind ... only works with static sites
mellow tide
but folks have used cactus to generate static content from django sites
modest scaffold
so i have to use either heroku or aws
mellow tide
or just follow that link you posted ๐
modest scaffold
it has no relation to django though
some weird thing called cactus
the only reason i linked it is because it was the only article on their site that even contained the word "django"
mellow tide
cactus is a static site generator that uses django content as it's source
ah, i forgot about pythonanywhere
that might work
modest scaffold
hmm
mellow tide
modest scaffold
looks reasonable
lethal orbit
VPS
mellow tide
wouldn't be what i ran a full blown production server on, but it'll work
lethal orbit
You can get a VPS for $2.50-$5 a month
mellow tide
wtfart is vps? lol
lethal orbit
It does take some initial setup though
modest scaffold
VPS sounds like a pain
dont you have to setup a firewall and config and stuff
and like permissions and storage
and bruh
mellow tide
technically, you should WANT to do that lol
lethal orbit
Yeah, but there are guides that tell you how to do all that...
permissions, not really.
modest scaffold
thats sounds like so much effort
lethal orbit
True
mellow tide
ah, you are one of those developers lol
lethal orbit
Don't deploy to production
mellow tide
the reason i have a job ๐
modest scaffold
wdym lolol
lethal orbit
Just have people come to your house and look at your screen if they want to use your app
modest scaffold

dapper tusk
depending on how you structured your DB, try post.comment_set.all

try post.comments.all I guess, at this point I am mostly guessing
somber aurora
port?
dapper tusk
typo
dapper tusk
what I generally do is send these things in the context dict, rather than making the DB query in the template
no idea why it does not work though
for example:
def politician(request, pk):
politician_ = get_object_or_404(Politician, pk=pk)
return render(request, 'politics/politician.html', dict(
politician=politician_,
stances=politician_.stance_set.all(),

))

hey does anyone here know wordpress? i need help with something stupidly simple
vestal hound
# Comments Model
class Comments(models.Model):
posts = models.ForeignKey(Post, related_name="comments", on_delete=models.CASCADE)
current_date = models.DateTimeField(auto_now_add=True)
comment = models.CharField(max_length=100)
def __str__(self):
return self.comment
@somber aurora your model structure is backwards...
well, not backwards but a bit weird
okay, I just woke up and I am not expressing myself properly
your model should be called Comment, and the field should be called post, and I would suggest you change the name of the other field comment to something like body
anyway, post.comments.all() (note small caps) should work
because it refers to the behaviour when you delete the related object
native tide
Never used django orm or sqlalchemy so was guessing
vestal hound
i.e. if you have models.CASCADE on the comment, that means that when you delete the post, the comments go too
the other way round wouldn't make sense
somber aurora

@marsh canyon there is no error, the carousel just pops and and disapears
to a completely blank container
marsh canyon
set an alt for the images and see if its even rendering
and are you getting any errors server side?

Yep

!paste
lavish prismBOT
marsh canyon
use this to paste code
marsh canyon
what flashes?
marsh canyon
so its appears and dissappears?
marsh canyon
remove the css links and see if the problem persists
ctrl f5 after removing css links just incase
heavy drift
all of the css links?
marsh canyon
whatever the page uses
heavy drift
it loads everything without the css
marsh canyon
so the problem is with the css
see if you got any keyframes wrongly configured
you want to look for animation in css, mainly the animation duration and animation-fill-mode
mostly all these will be in 1 line with the property animate
heavy drift
.animation {
-webkit-transition: all 0.2s ease;
-moz-transition: all 0.2s ease;

}
only thing with animation tagged
marsh canyon
:/
marsh canyon
lol, maximum value can be 1
marsh canyon
it does not disappear anymore?
heavy drift
Nope
heavy drift
but now it doesn't do anything its just static
marsh canyon
did you link back all ur css?
heavy drift
its also not switching between the other carousel
oh yeh i did that before
i commented it
marsh canyon
oh
marsh canyon
thats kinda expected haha
heavy drift
Umm, sooo....
the function is supposed to fade it to 0 oppacity and then fade the next one in
but now its just two overlaying each other ๐
marsh canyon
right
heavy drift
So its clearly not getting the javascript properly
but it could also be the animate.css file?
marsh canyon
im not expert, but maybe just using bootstrap cdn?
heavy drift
i can't because theres .js files it calls to which is in a modified bootstrap version
marsh canyon
is this project open sourced?
marsh canyon
kay
marsh canyon
you could try asking the question in a more web dev oriented server, more luck
marsh canyon
you could seperate the html/css/js files and use the modernizr
heavy drift
@marsh canyon also is there anyway to use ID tags in django
because they seem to not work
marsh canyon
@heavy drift you can try this server, much oriented towords frontend/javascript
https://discord.gg/devcord
what do you mean by ID tags
marsh canyon
sorry, never really seen that before
marsh canyon
yep
heavy drift
yeh django don't like
marsh canyon
u mean scroll link behavior?
heavy drift
Yuh
heavy drift
Right but this code works fine outside of the django ๐

for instance those carousel buttons

why is there is a .map
marsh canyon
try fixing the first 2 errors
i have 0knowledge of jquery
or just google the errors

i am
i don't think its related though
since the header is loading properly

i haven't imorted anything though
i think it just wants a bloody ref
as in language="JavaScript" type="text/javascript"
marsh canyon
try
marsh canyon
try googling Uncaught ReferenceError: $ is not defined django

maybe its only for jquery

nope
still didn't fix anything

(i am new to web dev and my site only has html css and js ) 
please ping me if someone can answer thanks in advance
gentle sandal
I was looking through the flask documentation, and came across thread locals. I can't seem to understand what they are exactly. Can anyone give me an example please
native tide
You have some examples of what thread_locals do
in the manual
go to your terminal and run FLASK_APP=app.py flask shell and in the shell, import the threading_local library like so
> import _threading_local
> help(_threading_local)
you'll see some cool examples, if you still don't understand let me know.

How to add authentication with access roles to Ariadne (Django) project?
lethal orbit
Use JWT
https://pypi.org/project/ariadne-jwt/ @valid cypress
Though it has some code WTFs I am not a big fan of...
You can also roll your own JWT implementation using PyJWT, like we have: https://gitlab.com/djangocities/djangocities
If you look at commits 12ac1dda - 26cca9bf, this is the JWT stuff (https://gitlab.com/djangocities/djangocities/-/commits/master)

OK, thanks
lean saddle

(i am new to web dev and my site only has html css and js )
native tide
If you want to set up a search bar system on your website I think Elasticsearch is a way to go. There are plenty tutorials how to do that, but there is one in particular that I like https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-xvi-full-text-search
marble carbon
elasticsearch ๐
native tide
?
lean saddle
@native tide thank you so much for this Sir but I only e made a website using HTML CSS and JS do I have to import the entire thing into flask or Django
native tide
Elasticsearch is a server package or service, it's available on Python using python -m pip install elasticsearch and it's also available on Java if you have a distributed system and you operate with microservices. You can probably achieve something similar using JS but I don't see why you'd do that.
azure saddle
Is there someone really good with html and CSS??
native tide
@azure saddle formulate your question and maybe someone is "good enough" to answer it.
native tide
Does anyone recommend any reading material for implementing React with Flask?
weary dragon
Hey guys, do you have any ideas of projects with flask that can teach me a lot when i built it?
jagged sonnet
@weary dragon see flask official website and follow the tutorial named tutorial. You will find it useful.
weary dragon
Thanks, but i already made some flask tutorials
jagged sonnet
oh. so you're intermediate.
weary dragon
Yes, i am pretty good with databases too
jagged sonnet
oh
native tide
What do you mean "projects that could teach me a lot"?
weary dragon
I know some stuff but i am not to confident to do some real world projects
native tide
What are the projects that you've done then? Describe them
weary dragon
I made a website that you can borrow games, a blackjack game, and some web scrappers all just for me and practice
jagged sonnet
you can make some api stuff with flask
native tide
Yeah you could start creating a Restful API and after that you could look into distributed systems. I mean that's what I do now, I started learning about microservices and how to containerize them using Docker & Kubernetes. You can then look into Travis CI which is a hosted continuous integration service used to build and test software projects hosted at GitHub
weary dragon
If i don't bother you can explain better what are microservices? I heard flask is for this but i don't really know what those are
native tide
Flask is not for microservices..it is indeed a micro web framework written in Python that is not as abstracted as Django and has less tools and libraries, but it s not intended for microservices in particular. Microservice architecture is an architectural style that structures an application as a collection of services that are: highly maintainable and testable, loosely coupled, independently deployable. If you think about opening a start-up and working with a team of developers in the future, microservices would be a vital choice.
You can orchestrate this microservices to communicate with each other using docker clusters and or kubernetes which will cross out the idea of single points of failures in your web app.

And it's there any advantace to know oop, like when i made blackjack game i used for it a object for game that manage game logic, what exemple of oop excluded databases objects are if exist
native tide
Ugh..
lapis spear
yo why is my static file not working i see not error 40* in my terminal but my styles are not applying to the page
native tide
OOP stands for object oriented programming and it's not related to databases ๐ It s a computer programming model that organizes software design around data. As you said, you can create complex objects, but that's not the point. You use OOP almost anywhere in the computer science industry. There are advantages: modularity for easier troubleshooting, reuse of code through inheritance, flexibility through polymorphism and effective problem solving.

I need help with oauth
Like I don't know where to start...
I'm using Django 3.0 alongside DRF.
I'd like to allow third party apps to use my API, in fact there's a couple interested. I've been able to grand read-only access without quarrel but I need to grant write access and don't want to blindly give a third party access to edit any user or post on behalf of any user, but I'm not sure where to start. I know in theory I need an oauth2 flow where users would grant the third party app access to their data, but how to do that... I've no idea.

this is not Django but Flask, but this might be a good starting point: https://blog.miguelgrinberg.com/post/oauth-authentication-with-flask

@limber laurel I'll look over them tomorrow. Right off the bat, I can tell you to look into.gitignorefiles and best practices. You shouldn't commit.idea, and you probably don't want to commit you database files either.
Also, good practice to have a README.md file in your repo root to have deployment instructions.

@zealous siren you can easily strip out the parts of Django you don't need, and the batteries included, auth, and account management mean that it's still a great back-end.
Millions of sites are powered by DRF, and many new ones use graphene or ariadne.
That's a good start, Mareks.

can y'all help me make sense of the pushshift API? I made this script to crawl subreddits, but it does not return all data like it used to:
start_time = 1483228800
batch_size = 100
request_fields = "fields=author,created_utc,full_link,num_comments,score,selftext,title,"
subreddits =["Bitcoin", "btc", "BitcoinMarkets"]
for i in subreddits:
for o in range(5000):
try:
response = requests.get("https://api.pushshift.io/reddit/search/submission/?subreddit={i}&after={after}&size={size}&{fields}".format(i=i, after=start_time, size=batch_size, fields=request_fields))
data = json.loads(response.text)
data = pd.DataFrame(data['data'])
start_time = data.iloc[-1]["created_utc"]
data.to_csv('{i}_{o}.csv'.format(i=i, o=o))
except:
print("Finished crawling /r/{i}!".format(i=i))
break
it does return a few posts but not everything like it should
for example i crawled a few subreddits in april and it returned 800MB of data in csv files. I ran the exact script again yesterday and it yielded 2MB
I dont understand what i am doing wrong here
well there definetely is. I ran the exact script from april again and it just returned 2MB of data instead of 800MB
and if your look into reddit and the subs there, there is definetely more data that is not returned
do you see any flaws in my script?
zealous siren
@lethal orbit you are still bring bulk that is django, and FastAPI/Flask come with critical parts you need for RESTful API
native tide
what i am doing is fetch 100 submissions starting in 2017 (start_time = 1483228800) and save them in a csv
then i take the last submission and take its timestamp (created_utc) and use it to make a new request to fetch the next 100 submissions
and repeat
lethal orbit
@lethal orbit you are still bring bulk that is django, and FastAPI/Flask come with critical parts you need for RESTful API
@zealous siren if you don't import/register views, they don't get imported. If you remove middleware, it doesn't get imported.
Not saying that Django is the only framework out there, but saying "it's heavy" is extremely ignorant, and saying "FastAPI is better" is short-sighted.
zealous siren
I gave my opinion, if you reach for django for pure RestAPI, you are making mistake generally the best way tos tart is go simple and build up, not go huge and gut down
lethal orbit
Yeah, start simple and add some third party ORM, and third-party user management lol
With Django you know what you're getting, and that is something stable, and tested.
Nothing wrong with SqlAlchemy either, but.... why reinvent the wheel?
If you don't need user accounts, etc. or even SQL, then it may not be the best fit, but there is ZERO wrong with using Django for APIs.
zealous siren
Because of SRE concerns, Stability, security
lethal orbit
lolwut?
zealous siren
DJango has bug, are we using that middle ware, I don't think so, but who knows if developer slipped it in
Django has security vulnerability, do we need to rush to patch or is it not a factor
lethal orbit
Somehow it powers Disqus, and Instagram...
Well, if it has a security vuln, then you need to patch it.
But other packages (especially the ones that are newer and not as well tested) are just as likely, even more, to have critical bugs.
Django is (generally) known for its safety.

@native tide A tip, when posting code snippits, if you put the code language after the first set of backticks but before the newline, it formats the code
Example:

becomes

Guys how do I implement react with flask?
Its so confusing
@native tide https://www.youtube.com/watch?v=YW8VG_U-m48&t=307s
lethal orbit
My recommendation: https://ariadnegraphql.org/docs/flask-integration
And https://www.apollographql.com/docs/react/ on the react side
Ariadne gives you a nice GraphQL API, and you can use React as a SPA
native tide
So, if you have a react frontend, you can no longer use render_template?
lethal orbit
So, if you have a react frontend, you can no longer use render_template?
@native tide ideally, no, you just use it as an API.
native tide
Ah, okay. Thanks for that. That's going to be interesting :)
lethal orbit
It does have advantages though... You can, for instance, use the API in Android and iOS apps.

Anyone used Flask-login before? I am having trouble getting the current userID when logged in.
User Loader
@login_manager.user_loader
def load_user(id):
return User.query.get(id)
## If i print user.query.get(id) it returns the user ID
class User(db.Model):
__tablename__ = 'users'
id = db.Column(db.Integer, primary_key=True)
username = db.Column(db.String(255), nullable=False)
email = db.Column(db.String(255), nullable=False)
password = db.Column(db.String(255), nullable=False)
profile_img = db.Column(db.String(100), nullable=False)
def get_id(self):
return self.id
User().get_id() returns None even when the user is logged in
hallow jacinth
you have to convert the id into an int

i am actually working on a log in feature as well

@login_manager.user_loader

thanks will try
Same issue
get_id returns None
if I print User.query.get(int(id)) after login, it returns the user ID. However if I call User().get_id() when the user is logged in, it returns None
hallow jacinth
You should call it as User.get_id()
past cipher
tried that too, didn't work
User class has to be initiated I'm sure
I've used flask=login in a bunch of projects, and never had this issue before
hallow jacinth
Ah, well i am not sure. I dont think it is necessary to create a function in the model when you can just use User.query.get(int(id)) to return an id
Sorry I couldn't help xd

that also returns None when calling it, strange
I give up for today lol, will try again tomorrow

are usernames automatically validated in django when using User.objects.create_user()?
patent shore
what do mean be automatically validated? Like if the username is taken or is the username correct when logging in? I user user.objects.create_user when a user signs up, but yeah django does a lot for us in the background.
@acoustic oyster
acoustic oyster
if creating a user does django automatically check if it is unique, valid i.e so restricted characters used?
I see I can call password validation and email validation manually
patent shore
Ah I see. I'm not 100% sure but I know that django forms won't allow duplicate usernames but I'm not sure about special characters- I assume it does tho
acoustic oyster
I am concerned because according to docs email and password are not validated when using create_user()
this is for registering a user via api
patent shore
My roommate suggested using the clean data function and form is valid. I'm still learning django too. I hope this helps
Netninja on YT goes over it he says

just a webpage that would run a python script
say open it up and it runs the script?

Not recommended. Especially with a ใใผใชใใ (CF8) recommendation against brython. I donโt know of another way and never used brython. Iโm throwing it out there as a โwayโ but opinion still stands
Depending on what you are doing, you could use a web framework to serve a page from a server, send requests from that page to the server, have the server process the requests, and either serve a new page or have the page change itself. More work but probably better but thatโs relative to what is your application

@nova nacelle so you're actually asking how to crop pictures?

What's best; Ask User for their Stripe API/Pub key or setup Stripe connected accounts ?
The reason I haven't really done connected accoutns is I won't take any fee, so isn't it a bit pointless to send to admin stripe account > then to sellers stripe account

I am using django channels and I am a bit confused, what exactly ties the websocket consumer with the view itself?
re_path(r'ws/chat/(?P<room_name>\w+)/$', consumers.ChatConsumer), Is it because of how this path is for the websocket pattern, and if so how exactly does it work?

@modest scaffold go to: https://dashboard.heroku.com/apps/<your_app_name>/settings
click add buildpack and select python.
i think it will solve your problem

@peak kelp from what I've read, Django has a lot of pre-built features compared to Flask. I personally use Flask for projects

hi,
i have made a tabbed image gallery, but im curious how can i costumize it in 3 more ways:
- i want when i first load the page there should be a default big image
2.that line of text that should be bellow, but isnt event though its outside any div tag
3.i want the 4 images to be in line with the big image, this will probably help with the second point too
Thanks!

Hi guys this is sort of an employability question. I'm learning Flask, React, SQL and AWS. What's the other in-demand technology that I should learn to increase employability?

Ooh thanks, docker is a definite one. Git too.
Btw I'm confused on the meaning of 'software developer', from all the jobs I've seen, its just full-stack right?

I'm interested in being able to load a page in Django, and filter the results based on checkboxes, text-fields, etc. but I really want to speed up the filtering as much as possible.
I have a view right now that queries the users once, and then filter's the list based on what filters are enabled.
Is it better to filtering through the view/database or to query once and filter on the front-end with JS/JQuery?
Also, on the front-end is there a good tutorial on filtering those results with JS/JQ? I can't seem to find anything too great and a lot of results require Django-filters, which I don't want to use in order to keep control of the code.

Hello, I am trying to build my own pastebin that I can run on one of my computers. With a pastebin I mean a program that automatically creates a webpage showing the content of a file (such as dpaste.com). While this will be usefull for me, I'm mainly doing this to learn more about how to build my own web server. I know that I want to build this in python with Flask, but I have no idea how to start ๐ฆ Could someone give me some starting points or tell me where I can find help?
jaunty quiver
look for a tutorial for a basic flask project with inputs (i.e. the famous TODO List App) and then modify the principles used there to suit your needs.

Hello guys, I'm building a simple api with just few routes, I'm using flask restful and I'm looking for "the best" architecture to build it, I'm currently looking to use Blueprint with flask restful and I wanted to know if it is a "good choice" or if there is something else I should check. The implementation is not a problem just want to know if there is other thing I should be aware of when thinking about architecture an api with flask. thx !

Im using my own cookie storage and wondering whether I should check (and delete) expired cookies per authentication or have a queue that does it for me?

I was going to suggest Miguel
@restive kindle depends what your app does. If it's churning a lot in the background, just do auth, otherwise, schedule it so as to better utilize your cpu cycles

i am a beginner in Flask and i am trying to do a login form for my site , i am confused between Flask-wtforms and flask-login , which one should i be using to make a login form ๐ค๐คฆโโ๏ธ
glass sandal
Thanks!
@fierce shell You can use the docs too . Django has one of the best documentations I've ever read , also Flask's docs are useful too!
native tide
@sage thistle I think you're confusing two different things. You can't choose between one or the other, however you can use both of them to create an authentication system for your app/service. Flask-WTForms is a great tool to help with form validation and can help create and use web forms with simple Python models. Flask-login provides user session management, i.e. stores the active user's ID in the session and lets you log them in and out easily, it lets you restrict certain views to logged-in users etc.
sage thistle
ooooo so i can use both of them @native tide
native tide
Yes, in fact you should if you're starting out rn and you don't want to code your own session management for authenticated users.
native tide
dw, good luck!

Can I return a page (with flask/quart), generate a file and then "push" that file to that page? something like (yes, I know this wont work as intended but it's just an example)
@app.route("/generate",methods=['POST'])
def generate():
data = await request.form
string = ""
for x in data:
string += x
str_hash = hashlib.md5(string.encode()).hexdigest()
return f"Processing File {str_hash}.zip"
# do stuff to generate the file
return send_file(f"{str_hash}.zip")
or will I need to do some JS or some other scripting?

you could return once, and send file as an argument

"yes, I know this wont work as intended but it's just an example"
so I want to generate a page, send it to the user saying "Your file is being processed" and then when its finished processing, send that file
past cipher
probably best to use JS to tell the user the file is being processed, call the route in JS too and wait for it to be processed & then redirect
fair tide
I did find "streaming with context" which might be able to do what I want (well at least update the page to say "Your file has finished generating, it can be found at this link")

honestly I'm not sure, never used that before

had to look up the quart variant, but it looks like it worked

@dapper tusk HM. I find it hard to visualise doing this with the ORM
(incidentally, since you describe it that way, is Stance a through model for the other two's M2M relationship?)
also, judging from your code, you don't just need to find the politicians, right?
you need the actual issues...
also, judging from your code, you don't just need to find the politicians, right?
@vestal hound because I believe this wouldn't be difficult
annotate with count distinct of issues by politician and filter on that
