@drowsy stratus Can you share your code?
You should share your ajax call
I'm not used to Django, but if you can share code within your your python application that receives the ajax call, it'd be nice too
im really dumb how do i attach a file in discord
Hey @drowsy stratus!
It looks like you tried to attach a file type that we do not allow. We currently allow the following file types: .3gp, .3g2, .avi, .bmp, .gif, .h264, .jpg, .jpeg, .m4v, .mkv, .mov, .mp4, .mpeg, .mpg, .png, .tiff, .wmv.
Feel free to ask in #community-meta if you think this is a mistake.
Pasting large amounts of code
If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pydis.com/
After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.
@drowsy stratus try using the character below 3 times between the first and lass line of your code, also add the language of the code on the first line after the triple
`
` (grave accent) not " or '
and the language name ( javascript ) should come just after the triple `
thx :>
Delete your code andj ust edit it, not to flood the channel :)
Try inserting "javascript" in the first line, without any whitespaces between the triple grave accent and the name of the language
wait is that incorrect too
$(window).bind("mousedown", function() {
$.ajax(
{
type:"POST",
url: '{% url 'clickPage' %}',
dataType: 'json',
data:
{
csrfmiddlewaretoken: '{{ csrf_token }}'
},
success: function(data) {
console.log("Success.");
}
});
});```
cool, much better
Here's an implementation of an request on my current working personal project, it may help you on that:
$(function() {
$('#mark_all_as_read').bind('click', function() {
// reaload notifications menu
$.post("/notifications/mark_all_as_read").done(function(data) {
$("#notifications-viewer").load(" #notifications-viewer");
$("#pending-notifications-counter").load(" #pending-notifications-counter");
});
return false;
});
});
Your success function is only printing Sucess in the console log, it doesn't seem to be interacting with your application
how do i get it to run the correct view from there
what's the route that should receive that post request?
I am really new to django, or any web developement, so I thought I gave it a url, the url module would see it and direct it to the correct view
is that what the route is?
or do I not have a correct understanding of django
I really don't know anything about Django 😅
What is exactly happening in your code
But I know that: You have to explicitly tell what's the endpoint that will receive that post request
My code only triggers a function in my App that marks all notifications from users as read, so it doesn't really need arguments.
I just need to point to the route
As soon it triggers that route, all notification as marked as read
which function triggers the code
This is my routes.py route that receives that POST request
@app.route('/notifications/mark_all_as_read', methods=['POST'])
@login_required
def mark_all_as_read():
for notification in current_user.notifications:
notification.pending = False
db.session.commit()
return(render_template('index.html'))
The javascript function I posted above,
It's bound to an event listener on the element which id = #mark_all_as_read, as soon the user clicks on it it triggers the post request
wait so does that post request run the method
Yes, exactly
wait, so you need to give the location of the method, and then that post method would run it?
Yup!
ok
@drowsy stratus Apparently I'm not completely right. Your code should be working from what I'm currently reading
both do not work
Tell me something
Can you hardcode url: '{% url 'clickPage' %}',for me please?
What's the expected out put of this?
i was expection to pull out cp
i made it so that if the url was "cp" the page would be redirected to the same template but it would run some script along with that
cp meaning current page?
yes the url of the current page
Let me check JInja documentation to check that out
what is JInja?
'Jinja is a modern and designer-friendly templating language for Python, modelled after Django’s templates. It is fast, widely used and secure with the optional sandboxed template execution environment'
oh so it is the python in html
It's what allows you to build stuff with {{ and { within your templates
ok 🙂
actully, in the python terminal, it tells me
[30/Nov/2019 20:08:54] "POST /clickPage HTTP/1.1" 200 669
or the post request
clickPage was the name of the URL i gave in the urls module
@drowsy stratus try {{ request.path }} if you want to point to the current page
Anyways, I forgot to ask you
What's the purpose of your function?
How should the website respond to mousedown
so I wanted to make a simple test app for learning django that every time i clicked the page, it will tell me how many times i clicked it. I made a model that would store that value, and every time I clicked i wanted it to add to a value in the model. This was just for me to test if my javascript could interact with the python
also i changed it and it did the same thing
it keeps on loading the default view again and again as well, as i put print() in that method and it writes to the terminal every time i click.
You want to update the number of clicks in your back-end, right?
yup :>
Cool
i just want to see if i can do a simple task
But "who" is in charge of storing the number of clicks?
a model called "pageClicks"
Can you paste it?
i gave it one value called "quantity"
and the "quantity" I will add one to, every request that view that i call from the javascript
As I said before, I don't know anything about django. But your Route for that View should somehow be able to capture that event, or should be updated by another source, which should interact with your object pageClicks, if I'm understanding it correctly
yah, I want the javascript to run some python
i guess if i can get it to run another way it would be fine
i just want to have a way to know that I know how to communicate the frontend and the backend, so i can work on other projects
Can you draw your process and what's involved with it?
It may help you and me
Somethign like that
ok
What interacts with what, in which file, which functions, etc.
Do you want to store it in a database of somekind?
oh i should of drawn that
The number of clicks
yes that is in a database
that could be referenced and edited by the views
i just cannot get the javascript to run the clickPage method
I cannot get the javascript to respond back to any python
BRB, I'm playing a match
never mind, i figured it out. i just saved it into a json inside one of the flask functions so that when that site is accessed, the json is updated
Has anyone here implemented Flask-GraphQL views?
I'm getting ModuleNotFoundError: No module named 'graphql.error.base' and indeed when I check the dir here's the result:
I’m trying to find a third party tool that can help me create a live chat app with flask. Can anyone recommend any? I would prefer to be less on the js side but if it is that’s fine.
@fair wraith Never done, but I think flask-SocketIO is what you're searching for
That may help
ok never mind, my solution didn't work
i still need help with it
how do i save flask.session into a JSON permanently?
is this even possible?
@sly canyon ya ik about SocketIO but I use python anywhere for hosting and they don’t support it. So I have to use a third party tool 😦
@fair wraith switch to https://repl.it it's way better
I’ll check it out. But is there any well known third party services that provide for a live chat in flask
Which kind of session are you talking about @winged island ?
A Session from Flask-Session?
@sly canyon no, just whatever comes when i do flask.session
idk how it all works, really
What kinds of information do you want to store?
im using youtube data api
so credentials and state
it's already in a dictionary form, i just have to save it before it goes away
@winged island
import json
#....
with open('data.json', 'w') as file:
json.dump(data, file)
right, i know HOW to do it. but wherever i put that code, it either runs AFTER the session has ended OR it just doesn't do anything.
i need to find a place to put that code where it'll actually be properly saved
Where's your request?
You're probably running some javascript request to retrieve data from the API
Is session1 storing anything at all?
@winged island check what's the output of google.oauth2.credentials.Credentials(ytAuthJson['credentials'])
and googleapiclient.discovery.build(API_SERVICE_NAME, API_VERSION, credentials=credentials), because I'm really not sure what is.
I think you should do something like
flask.session['credentials'] = credentials
Or maybe
flask.session['token'] = credentials.token
if it's a class object with some attributes
hm
yeah
but that's not my problem
i just want to be able to access what WAS in flask.session before i ended the session, and be able to access it AFTER the session has ended
most preferably in JSON format
@sly canyon
But where exactly in your code is there the varible that stores the information that you want to save?
Because I feel really lazy to try reading it all and understand
flask.session is what i want to save
everything in there
wait, you want to know how the stuff gets INTO flask.session?
that happens in lines 87 and 103
@sly canyon
@winged island but what's the purpose of line 45 then?
i just wanted to see if i could jsonify it myself
but it hasn't worked
that's why lines 52 and 53 exist
@winged island right, but does dict(flask.session) really returns a dict with the session information?
yup
it 100% does
i've checked
i don't want to send its output here because it's got credentials inside, which i don't want to reveal
Have you tried
with open("config/ytAuth.json", "w") as f:
json.dump(dict(flask.session, f, indent=4)
?
yup
What happens?
it depends on where i put it.
if i put it inside /app it works sometimes
if i put it inside __main__ it doesn't work
if i put it right at the top, it doesn't work because the session hasn't started yet
wait a second
i could just take credentials and state DIRECTLY instead of from the session and just put THAT in a json
right?
Yes
Try saving your state on line 88 and your credentials on line 102
just after you receive it
@sly canyon it worked! thank you so very much!
NP, U figured this one out yourself
Hey, I built an web app using django+react+postgresql that I intend to run it locally. Should I deploy it to an web server like Apache or run it with runserver --insecure ? An max of 5 people will be using it at the same time. It will not be used online, only on local network. If I should deploy it, which web server do you recommend?
Or should I use debug=True, since it will be used only by people on my company
and it will be easier to debug if something happens
So i am using django-oauth-toolkit in order to provide oauth2 authentication for my android application. Now i have to implement social(facebook, google) authentication. And my workflow should be like when user hits signup with facebook button it does authorize successfully thanks to python social auth. So as it is supposed to be, python social auth does create user and it is fine. Now, this case works fine on side of web user. Problem is how can i handle android user tries to login with facebook?, Do i have to pass facebook authorization token to oauth toolkit?
I have a search bar in flask. Now I have a submit button to it, which is this line
submit = SubmitField("Submit", validators=[DataRequired()], render_kw={"class": "btn btn-secondary"})
It works but I want that instead of text in the button, which now is "Submit", I want it to be that magnifying glass icon. I tried to substitute the first string parameter with the <img> tag, but that did not work..
hi everyone, did anyone use django as back end development ? I wanna ask about the online tutorial resource, where do you find complete tutorial about django ?

Hello. Anyone here worked with Flask-SocketIO in production? I have some questions about running a websocket server under a load-balancer...
You have a point but it is not enough for themes in flask
How can we use js and css codes in it?
https://stackoverflow.com/questions/24589123/how-to-cache-sql-alchemy-calls-with-flask-cache-and-redis can someone give me an example of how to access the cache outside of the flask main file?
every example i have seen is using cache in a single file and i havent figured out how to access it in another.py file
Can someone help me with this? There are only 2 instances where my function isn't working and I'm having trouble fixing it
@manic siren this is web-developement channel
I was told by @spare tundra to come here. Sorry about that!
that's js, so it doesn't belong in any of the general help channels
so here would prob be the best place to ask, at least on this server
dude that's not even python, are you serious ?
the topical sections have a broader allowance for related things. Granted this isn't really web-dev code its just straight up JS.
tho maybe #algos-and-data-structs would work for any trouble with the the algorithms
or #ot0-fear-of-python , #ot1-this-regex-is-impossible , #ot2-the-original-pubsta Worst case
I'm using Flask-Login on my application, but I want to improve authorization on my routes by assigning User.roles to my Users objects and parse something like @roles_required on certain routes to only allow access from users with certain roles, can anyone recommend me a library to deal with that?
Hello does anyone know a way to search for anything on your own website (localhost) ?
@sly canyon like this? https://flask-user.readthedocs.io/en/latest/authorization.html
@muted silo I don't think there's any general way

HI ,I am developing website in flask,and stuck at point where the results i am getting on from my search i want to display it on next page and i am not able to extract selected any pointers will appreciate
search result
for example if user select of hyperlinked item i want to capture and display it on reults page
i started something like below
@app.route('/Results', methods=['GET','POST'])
def results():
if request.method == "GET":
form = BookReview()
ReviewItem =request.args
but not sure how to proceed ... 😦
hi all!
I am new to this forum
just wondering if anyone tries the gRPC with python?
can somenone help me about theming in flask?
@marsh canyon Ok, thanks alot dude
I have chatbot which talks in websocket
from fastapi import FastAPI
from starlette.websockets import WebSocket
import random
app = FastAPI()
@app.websocket("/ws")
async def websocket_endpoint(websocket: WebSocket):
await websocket.accept()
id = random.randint(10, 10000)
while True:
data = await websocket.receive_bytes()
if data == "Hey":
print(f"Hey User {id} : {data} Acknowledged :P")
await websocket.send_bytes(f"Hey User {id} : {data} Acknowledged :P")
if data == "Hello" :
print(f"Hey User {id} : you already said Hey :P")
await websocket.send_bytes(f"Hey User {id} : {data} Acknowledged :P")
else:
print(f"Hey User {id} : Start with Hey instead of {data} :P")
await websocket.send_bytes(f"Hey User {id} : {data} Acknowledged :P")
I wanna build a layer over it so even rest request can talk according to each user
Here is a python script which establishes web socket connection for each client
https://paste.pythondiscord.com/hamogivabu.py
and here is a script which invokes the above script according to user
https://paste.pythondiscord.com/jiqonipoki.py
can anyone provide a better solution
Like maybe replacing webscokets with redis to maintain context of each user ?
I tried but it was not working
going in infinte loop
that it was working for one client but not more than one
That's why I tried calling it as a subprocess
@crystal rain I dont think web socket sync would solve this
what is this in reference to?
Hi, can someone help me w/ Django?
!ask

• Show us the code you've tried and any errors or unexpected results it's giving.
• Keep your patience while we're helping you.
You can find a much more detailed explanation on our website.
Does someone have any idea about bootstrap theming in flask?
That is for templates

Hello ! I'm coming from desktop (pyside) application development for CGI softwares (maya, modo, nuke, mari), so my knowledge in programming is very specific to that area. Although I'll need soon to develop a web application for managing our film productions data, so with a quite rich UI. Knowing nothing about web development workflow, I'm a bit overwhelmed by my researches so far. I won't ask which tool I should use, I'm only asking if there is somewhere a simple article that you'd recommend that explain the world of web development ? I read about react/vue/angular flask/django, I see about quite scary stacks, but I don't know nor understand who does what. So if you have a nice article explaining the basics for a slow-learning beginner like me, I'd be thankful 🙂
@devout quiver what's your question?
@manic tree I don't know any specific articles sorry, but maybe you could begin with looking up what the diff between front-end and back-end is, if you don't already know the difference
Django / Git question: What is the typical "flow" if you need to make a migration and then commit? Do you 'makemigrations' then 'migrate' then add/commit? Or is the add/commit before migrating? Thanks
Doesn't migrate just apply migrations to the database
and the database of course does not get checked into vcs
so it doesn't really matter
but I suppose it's good to know your migrations successfully get applied before you go ahead and commit them
hey guys, I just picked up Flask (we use Django at work and it's a bit of a black box for me, plus it was overkill for what I have in mind). For the Python backend, I use esper (an Entity-Component System). two questions: would you use the database for communicating between the back and the front, or just JSON encoding/decoding? and second, for a text-based game, sort of what is known as MUD or MUSH, would you use DOM or some sort of a canvas-based solution?
I already have a barebones skeleton that uses JSON for communicating and just displays JSON content on the website, but just showing JSON obviously won't scale - I intend to take it at least as far as the Python roguelike tutorial does (Esper example here: https://github.com/abesto/pyrl - so a map, some enemies, player inventory, some usable items, extremely basic combat engine, field of vision and save/load)
Followed along http://rogueliketutorials.com/tutorials/tcod/, but with Esper ECS - abesto/pyrl
I know that technically what I'm thinking is possible, as we have Evennia (https://github.com/evennia/evennia/wiki/Getting-Started) - a full fledged Django-based MU* engine
Hey, i've been searching for a bit for this. Does anyone have a solid tutorial that shows how to set up Vagrant to run a python 3-based web server so I can develop locally?
I'm a C++ dev, not a web or python dev, if that matters.
I was using puphpet for a while, but that was over a year ago, and I'm not familiar enough with configuring that stuff with python (it's puPHPet, after all...) to pick the right settings.
alright, I found this from 2016:
@odd locust last I checked, vagrant was supsrisingly easy. The tricky bit is choosing a distro.
probably best to choose one you're familiar with
once it's booted and you can ssh in, then it's just linux; and the fact that it's vagrant is irrelevant
Yeah I've used it before with php. But not with python.
I'm mostly on OS X, never on linux.
Does anyone here have a preferred vagrant config they use when running a VM for developing web apps built with python?
@quasi ridge any thoughts or suggestions?
I've never done it seriously but I think I just slap in ... uh ... Debian? Lemme look to see if I have some notes about what I last used
I think centos7, mostly because it's vaguely similar to Amazon Linux, which is what I use IRL
ok
I'm trying to set it up now, but have no idea what i actually need. I know i'm gonna eventually do some database interaction, so probably gonna need SQLite, but no idea on the CRON jobs or Mongo or whatever other options they allow
those are all legitimate worries, but your choice of distro, nor how you configure vagrant, probably doesn't matter much; what really matters is what stuff you install with your package manager after you've got vagrant going
personally I'd make sure I have python3 -- from the package manager, if the provided version is reasonably new -- and pip from the package manager. From then on I'd use pip (or pipenv) to install whatever else you need
you might need to install some libraries like ssl or what-have-you, in case you want to install python modules that have C components
I'm running into this:

bah, why can't I get python 3.7
Is there anything tricky with creating a task queue, and having those tasks perform web requests, and returning the result of those task requests to the web client?
any thoughts on this one?
pip install upgrade pip
Collecting upgrade
ERROR: Could not find a version that satisfies the requirement upgrade (from versions: none)
ERROR: No matching distribution found for upgrade
WARNING: You are using pip version 19.2.3, however version 19.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
yes it means u should update because the recuirments aren't meth
@odd locust try pip install --upgrade pip -- that is, use two dashes before "upgrade"
also, in order to get python 3.6, you might need to tell apt to use a repository with newer stuff, or even build python from source
pretty sure there are alternative apt repos that will have python 3.6
debian stable includes python3.7 (https://packages.debian.org/stable/python/) so I think you're using an out of date distro
I mean the fact that the previous version was "none"
can I use the same Redis instance for a RQ backing and to cache data? or should those be separate instances?
i would say separate them
ok
is there an easy way to be notified when a job is done, so I can act on the result? I'm making an app where, the user signs up through a 3rd party sign in, and then I want to pull a bunch of data in repeated requests from that 3rd party.
Hello, which view in DRF are better? function based or class based?
Hey does anyone know how to set up VSCode to debug django stuff that was spawned via python3 manage.py runserver ?
so I can trigger breakpoints and inspect variables..
alright, I found this: https://code.visualstudio.com/docs/python/tutorial-django
run.py: ```python
from chatapp import web_app
if name == 'main':
web_app.run(debug=True)```
init.py: ```python
from flask import Flask
web_app = Flask(name)
web_app.config['SECRET_KEY'] = 'temporarykey'```
and routes.py: ```python
from chatapp import web_app
@web_app.route("/")
def home():
return 'home page'```
I am not sure if this is some bug, or I'm making some fundamental mistake here. Google isn't returning anything useful on this. Thank you.
thank you, that did fix it. I just figured flask would automatically search for routes.py, as it does with templates in the template directory as a default path
nah flask is a microframework - I wouldn't think it would do that
I don't know, maybe a little bit too much django rubbed off on me
thanks for your help
In Django or other web frameworks, say someone uploads a video, the server handles resizing the video, then allows the user to download the processed video (made up example). Should that somehow be transfered back to the user through the static file system? (NGINX transfering the file instead of Django/gunicorn), or is it OK to transfer it straight from Django?
If the former, how does that work in practice?
@lofty matrix It sounds like you could just have Nginx handle that part, perhaps by having those kinds of requests fulfilled by a separate subdomain that does nothing but that.
Basically, you do the resize job, place it on a file system according to some naming scheme, send the person a download link, and then route it through some Nginx mapping that does nothing but read from that particular file system, etc.
That makes sense, thanks. What if I wanted permission to download that file associated with their account, which exists within django? (so if you sent someone else the link, they could not use it) Could django establish the NGINX connection somehow?
Are these files things you want downloaded within a particular stretch of time, like a link that expires?
In this example, yea, they would probably need to be deleted after a few days/hours, but in a different one I could see the link being semi-permanant
Take google drive for example if you're familiar with it. I can send a link to a file, and when someone visits it, it makes sure that they are authorized to view it, maybe they're authorized to edit it. Then the download happens, and the permissions are a part of that somehow
As far as permissions go, I think there may be programmability in Nginx that might help with this. I would not be inclined to burden Django with multi-megabyte file transfers all the time (although I suspect the burden would be more about number of connections than amount of data transferred, but I say let Nginx handle what it's best at)
I am not as familiar with Nginx as I need to be to give a good answer, I'm afraid, but I do think it would be best to see how you could have Django configure Nginx, maybe even on a URL-by-URL basis, to check for credentials (maybe by way of an API call)
problem with having django handle that is that one worker won't be able to do anything else while it's streaming a big file. if you have a slow client, that's awful, and nginx can handle that with ease
Exactly my thought as well. Django 3.0 now supports async, but I suspect that's not the answer you want to hear :D
There is the potential of passing a "key url" that is unguessable, which wouldn't require manually configuring nginx
I think what he wants is for a user's Django credentials to be the key.
It doesn't necesarily have to be credentials. Maybe it would increment a counter of how many times the file has been accessed. Some sort of processing occurs within django before the file is served. I'm thinking that utlimately it might end up being a unique, unguessable URL that is served by your web server at some level
So that's the basic answer, I guess :D But yeah, you don't want to tie up Django with serving large files if you can help it.
At least not until their async story gets a little more robust.
How do I prevent a logged in user (server/profile/user) from accessing another user's page in Flask. For example if the 'user' user changes the path to 'server/profile/user2' he will be able to see user2's profile. How do I prevent that from happening?
I'm using Flask
Nevermind, solved!
@native tide do you mind sharing your approach?
How can i link to another webpage inside an object tag and have the whole page be directed there not just the object tag (Django)
@mortal bear can you explain this one further? I didn't quite get it, illustrate if possible or show the result vs the expected output
@sly canyon I have a html file with some code and to display this i use the object tag. But whenever i click the link which is inside the object tag the link doesnt redirect the whole page, it will only change the object tag.
not really too sure how i can explain this

I dont understand why I get this error?
its django Im using the restframwork
that error happens when i run migrate
class getVals {
constructor() {
this.sForm = document.getElementById("SearchForm");
this.getRequest = "?&";
this.getNext = false;
}
checkVals(ele) {
if (ele.checked) {
this.getNext = true;
} else {
console.log(ele.checked)
this.getNext = false;
}
if (getNext) {
this.getRequest += "&" + ele.name + "=" + ele.value;
} else {}
}
submitSearch() {
Array.prototype.forEach.call(this.sForm.elements, this.checkVals);
// for (var i=0; i<this.sForm.elements.length; i++) {
// checkVals(this.sForm[i]);
// }
console.log(this.getRequest);
return this.getRequest;
}
}
New to js, why do i get the error : cannot set property getNext of undefined?
@native tide can you show the full traceback?

I want to make a Flask project that lets people upload a file and then run Markov Chain text generator on it, and return some amount of generated text. Thats pretty easy to write the code for - but I want to do as much of it as I can to a professional standard - as such I have no idea how to structure the project, are there any good resources which can point me towards a sensible project structure?
you could look at how cookiecutter-flask is structured
Looking at it, I understand what most of the individual things are doing - but I have no idea why its structured the way it is
i got this error in django
(1091, "Can't DROP 'link'; check that column/key exists")
what do i do
i removed one of the fields, it was long before, but now i am getting this error while trying to migrate
single or multiple repositories for microservices?
this is somewhat a cry for help and also just general whining: does anyone else find the flask infrastructure extremely confusing? It looks like it's in a state of flux where most of the docs (and plugins, and extensions, etc) still reference the old, non-factory style architecture ... but the tutorials and quickstart insist you use the factory method. Makes it sorta hard to transition from the quickstart to doing anything useful, or I am ... really just very stupid
I followed along and implemented the "flaskr" tutorial in the docs using the 'flask run' development server for testing, and I want to test deploying with uWSGI but I'm not actually sure how to bridge that gap right now and can't quite find info in the docs that gets me cooking there
it looks like uwsgi probably does not understand the magic method create_app in the same way that flask run does, so I need some glue code there, but I'm not sure what sort of glue to write, exactly
if anyone has some good reading links or some help to throw my way, I would be really appreciative!
@north perch Flask is one of the simplest frameworks for python IMO. Different frameworks work better with different people depending on their preferred workflow. Many people swear Django is a breeze and very streamlined, yet for me it is one of the most confusing web frameworks across any language I've developed web apps in. I prefer a very barebones DIY starting point that I can build upon, and tweak to my liking. So i tend to use express for node.js apps, and flask for python apps.
For your specific issue
For Linux, Mac, Linux Subsystem for Windows, Git Bash on Windows, etc.:
export FLASK_APP=myapp
export FLASK_ENV=production
flask run
For Windows CMD, use set instead of export:
set FLASK_ENV=production
For PowerShell, use $env:
$env:FLASK_ENV = "production
Then you can wrap your flask app in something liek gevent, flask-socket.io, etc for testing
specifically I'm trying to figure out what the "right" way to deploy an app with uwsgi is when flask uses the app factory method
I got uwsgi -w flaskr:create_app() to work but am not sure if this method has any drawbacks that I might not be aware of
most of the tutorials do not assume you are using the app factory method
Many do, they have a setup similar to what's found here https://flask.palletsprojects.com/en/1.1.x/patterns/appfactories/
Does anyone here use FastAPI
in jinja2 templating, can you do logic using {{ }} and {% %} syntax inside of an included template?
include as in the keyword as opposed to block or extends
if so... do you have to render that includes html file before rendering the more base level html?
I'm trying to use https://flask-user.readthedocs.io/en/v0.5/authorization.html in my app. But I currenly use mysql instead os sqlalchemy
is this possible?
Mysql and sqlalchemy are not the same thing
Mysql is a database that hold data and sqlalchemy is software which commnicates with your database
You can use both
Is there some way to make my bot create a new file on my website and put code on it?
yo so
just wondering
when you select a link from the dropdown, how can i get it to close the dropdown and just show the page?
@cyan wolf I dunno about anyone else, but I for one have no idea what you're talking about
ok so
this is my website
that is the dropdown
if i click on about, i am routed to my about page
the top bar is kept open when the page is opened
how do i make it close when im routed somewhere
wait looks like it already does
but now half my dropdown isnt routing
no idea; it probably depends on whatever stuff you're using to generate that page
I imagine you're using more than that; neither of those contains code to display the (rather-nice-looking) web page you showed earlier
Yeah, it sounds rather like a CSS/HTML problem specific to your code
I imagine you can find a boilerplate type thing on w3schools that you could copy over if thats the issue
Im using the latest bottle on pythonanywhere. Im having a problem with my website. Its not loading this part of the site everything else is good. Is there something wrong with my python code. I need some help im new to this.

Hi,
I want to implement social login feature in a django backend application. I have used dejango_rest_framework. Which librery would be best for me to do that job with a proper documentation?
@mossy shell try django built in Token authentication, it works very good
I hope it's easier to use than OAuth ... never could figure out how to do that
Not to advertise or anything but Engineerman posted a really good video about OAuth2
and how it works
I can't see anything wrong with that kind of "advertising"
just saying, mods here are really by-the-book and i can't really blame them
Hey guys, I'm using Flask and I'm trying to create a cookie for my parent domain. I added dev.xyz.com to my hosts file and I'm trying to create a cookie for .xyz.com, however when the cookie is created, it just uses dev.xzy.com and not what I set. I'm able to create the cookie correctly with JS, so this makes me think there is some config variable I need to change, but I'm just not sure which one. Thanks! 🙂
I also have a flask related question but I am unsure how to go about explaining it. I want to alter a python script I already have to run by me inputting a url into a search insert on the flask page - and return the response not as an html table, but as an input form with ability for me to edit anything I need to and submit to be added to a database table. I have the code that I based my currently working python script off of but apparently the way that is written, it returns the json and I'm having trouble trying to figure out how to alter things so it does what I want.
Links available for both script I based stuff on and my current script i run manually in the python console if desired//needed
I'm at a lost here, is there really no Flask captcha implementations that are not obsolate? I don't want to use recaptcha, nor anime related captchas.
Related: https://github.com/DangerOnTheRanger/maniwani/issues/130
What's wrong with https://pypi.org/project/captcha/ ?
I've used it before (albeit for a GUI app)
Huh, for some reason I didin't come across that one yet.
It may be getting unmaintained but it was working when I used it in March
This at least is unmaintained https://pypi.org/project/Flask-Captcha/
@hollow flower flask_wtf had recaptcha field and works seamlessly
I don't want to use Google's phishing services, thank you.
I'm trying to find a solution which is not Google tied nor tied to any 3rd party services, like Google's recaptcha and you cannot use it without JavaScript.
👀
talk about paranoid
Lil bit
I mean for capcha they do have a lot of trackers so sort of understandable
That and it's contributing to Google ml if you care about that
But capchas need trackers to make it easier to see if you're a human or not

hi, I have a question regarding socketio and deploying to an ubuntu server. My code works perfectly fine in my dev environment, but I get an error on the last gunicorn command to start it.
run.py to start it: ```python
from app import web_app, socketio
if name == 'main':
socketio.run(web_app, host='0.0.0.0')```

from flask import Flask
from flask_socketio import SocketIO
from flask_sqlalchemy import SQLAlchemy
socketio = SocketIO()
web_app = Flask(name)

web_app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///site.db'
database = SQLAlchemy(web_app)
from .main import main as main_blueprint
web_app.register_blueprint(main_blueprint)
socketio.init_app(web_app)```
and server logs: ```(venv) mark@server-demo:~/squintsyfinal$ gunicorn --worker-class eventlet -w 3 run:socketio

its a starter project to learn this stuff and I'm just struggling to fix this. I'm pretty sure the problem is somewhere in run.py regarding the socketio variable, but I'm not sure.
And to reiterate, this code runs perfectly fine locally
Are you starting it locally via the same gunicorn command?
Because that won't work-- gunicorn must be passed the flask app, not the socketio adapter
In your case, that's web_app @native tide
locally, I was just using the flask development server, not gunicorn. but changing it to web_app now makes it run, I think all thats left is for me to add socketio config data into nginx so this is a huge leap forward in progress. I thought I'd have to send socketio and not my flask app because it is "wrapped" with socketio
but thank you very much for your answer
👍
hi

i know.i will learn one of them
Can Django be used to build an institutional level trading platform, or will it be too slow compared to Java?
@mortal bear I believe discord has their own embed you can use
Do you know where i can find that? The inbuilt widget one doesnt have ana invite code
i dont think
it should
You can also just take a screenshot of an invite link and turn it into an image, not the most responsive, but that's how discord did it in emails lol
hmmm ok ty
Hi guys,
I have a quick question. I am developping a web site Flask based, however I have a little issue with my html bootstrap code as my nav bar is always displayed in vertical position whatever the class I use or the CSS I use. I even tried to override by css but no result have anybody face this issue before ?
Do you have a snippet of the CSS you're using?
@unique willow try using the dev tools in your browser and inspect the navbar element in order to see what's causing it to behave like that. That way you can see the Styles applied to it and the source files containing those. You can then delete or alter the code to know what to do in order to fix it.
You may be using class = d-flex flex-column as a wrapper and it's causing it to be a vertical container
is anyone good with html / css?
@sly canyon thanks i will do that right now
@solar hatch Corey Schafer
How do I store data from google map api in JS to a django form field?
@sly canyon thanks a lot you were right the it was flex colomn
Anyone got a suggestion for a cms? Thinking mezzanine/dajango-cms/wagtail.
so say i have computer a which is local, and a remote computer b. theyre connected by a vpn tunnel. computer b has a server on it with a web client.
from computer a, i can enter the ip and port and connect to that servers web client. but i can not use the dns entry to connect. but on the server itself i can use both the ip and the dns to connect. i can also from the local computer use the dns or ip to connect to any of my other servers web clients, any idea why?
local -> direct ip -> server [✓]
local -> DNS -> server [X]
server -> direct ip -> server [✓]
server -> DNS -> server [✓]
any ideas?
What does the DNS resolves to ?
as in what ip does it go to? same one im manually entering which is 10.104.55.101:8080
so 10.104.55.101
well yes, still have to add 8080 to the dns
That's weird. Just for sanity, on local what's the result of you pinging the DNS ?
cant find it
Well here's your problem. Dunno what DNS server you're using but either they haven't full propagated yet or you're not using the same
we think we found it, it looks like the guy in charge of adding the new static ip to the filter policies on these remote routers didnt reboot them after and that is causing this
just for education, DNS doesn't care about ports
hostname -> IP is all DNS handles when talking about HTTP, everything else is taken care of outside of DNS
So I'm trying to figure out a way to display different froms on my page. Depending on what the user selected in a dropdown list, using Flask.
Would this be possible without having to have to user click a button to send the selected dropdownlist value?
I have a webpage where my Django backend is creating a bunch of <a href> links via a Jinja template. Based on whichever link the user clicks on, I want to make a jQuery AJAX call to a specific URL, but I need to differentiate which <a href> link the user clicked on. In Javascript, you'd do something like onClick="myFunc(x,y)", where x and y are unique per <a href> - how do you do this in jQuery? I get that I can figure out what they clicked on by the $this - would I just store a couple of variables in the <a href var1="x" var2="y"> and access it that way?
$(selector).click(function() {
If you have a custom tag on the href, $("[my_custom_tag]").click()
@native root Sorry for the ping but is it normal to find GoogleDriveDS under Application on a website
And I have the option to delete the database
Thank you!!

if anyone is familiar with selenium, is there a way to wait for an element to change (not load in), then continue with the code?
A rather simple question that I can't seem to find the answer to. How can I access the body of a POST request within python when executed as cgi under apache?
@mossy maple use the cgi module
if you're not doing that, post request body is in stdin though
Does apache/whatever really just feed requests to stdin?
That's probably the kind of thing I should know
that's how CGI works
bunch of stuff goes in environment variables, request body goes in stdin
Oh sure. I didn't realise that, definitely the kind of thing I sold have known
Data input to the CGI script
As there may be a data entity attached to the request, there must be
a system defined method for the script to read this data. Unless
defined otherwise, this will be via the `standard input' file
descriptor.There will be at least CONTENT_LENGTH bytes available for the script
to read. The script is not obliged to read the data, but it must not
attempt to read more than CONTENT_LENGTH bytes, even if more data is
available.
Random, thx read from stdin

anyone used FastAPI before?
@ripe pecan
i started to use it few days ago
are you liking it?
i really like it
i started at flask, then had to move to async so used Sanic
and now trying fastapi
it feels elegant, you have everything and it just works
some of the docs could be better but it's still work inprogress
Yeah, fair enough. I've mostly only used Flask and Django
Hey @native tide!
It looks like you tried to attach a file type that we do not allow. We currently allow the following file types: .3gp, .3g2, .avi, .bmp, .gif, .h264, .jpg, .jpeg, .m4v, .mkv, .mov, .mp4, .mpeg, .mpg, .png, .tiff, .wmv.
Feel free to ask in #community-meta if you think this is a mistake.
I am following along to Python Crash Course, I am currently on Chapter 20. I have done some styling in base.html and index.html and when I went to run my file to test the look and feel I get the following error. The total line count of the error is 72 lines. I will upload the error to github so you guys can see it more in depth. Unless the line below explains.
OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: '<frozen importlib._bootstrap>'
so a friend needs a mobile/responsive? WEB UI that can be used from mobile or tablet or PC to gather some basic data . I was thinking of using on the server Python/Flask/MySQL any guidance or other items I need in my stack? I have a windows 2012/R2 server so pointing the DNS/name to that IP will be easy.
it depends how big is the website
if it's really big, django is the way to go
react or vue is good for frontend
Saki: I'm interested in learning flask, but how big would be "too big for flask"
I don't think "big" is the issue
django has a ton of features, particularly database stuff; afaik, flask is leaner. I personally have only used flask for routing
From experimenting with each, I have noticed that with flask you basically have to build a lot of the functionality that Django has by default. With Django you basically have to play by its rules, often by overriding it. However, it saves a ton of work compared to flask because that stuff is already coded. It is just a matter of learning it.
That said... One thing that royally irritates me about django is that I feel like it violates the DRY principle. You want to make a form? Well you'll need to create a models.py (and also used in migrations file) and state every field with their types. Then you make the forms.py which you again have to refer to the model and specify each field. Then, in the view, if there are any special cases you have to specify them once again. It's a pain. And it makes me feel dirty when I do it.
What's the DRY principle?
Don't Repeat Yourself
Generally, it means that you should not be writing the same thing in two places, but more abstractly it can mean "If I want to change a distinct detail, that detail should be specified in only one place"

Hello, using python version 3.8 , django 2.2,
i am beginner learning django building project by following tutorial, everything going fine but suddenly my admin page refuse to connect 'This site can't be reached' but my blog localhost connects fine , any code i run to refresh my settings or which approach i shall take? Thanks
i tried following this answers : https://www.reddit.com/r/django/comments/bt77m2/this_site_cant_be_reached_127001_refused_to/
but not worked for me
@solar hatch to active your pipenv run this :

To clarify, the admin pages used to load, but now it suddenly stopped working?
yeah my latest actions is i created a model , render it with the views.py
also when i run the server , the terminal keeps sending this message over and over:

Hi
getting an error from my python/flask based website:
only traceback is to the last line of this code:
@app.route("/")
@app.route("/home")
def home():
page = request.args.get('page', 1, type=int)
posts = Post.query.order_by(Post.date_posted.desc()).paginate(page=page, per_page=5)
return render_template('home.html', posts=posts)```
the link suggested is here: https://flask-login.readthedocs.io/en/latest/#how-it-works
this is only an error with my new code, which ive made add a collection of all user post's individually viewable with their profile
ping me if you have any ideas on how to fix this, or if you need some code
@cyan wolf reboot your running process
Will do
You probably have debug mode on and have re-done some stuffi n your code
And you're probably using flask-user
I think you can list running processes with pgrep -f python on bash
Then just kill -9 [id]
and try flask run again
If for some reason there's still a flask task running in the background
Cool, GL
Cheers
@sly canyon just did that, booted perfectly! Thank you again!
@cyan wolf Cool! Glad I've been able to help

with inputs, what's the difference between Name and ID?
like something like this:<input type="email" name="Email" id="Email" />
id is the HTML id you can access via javascript and css
name is the name that it will be submitted as
You are not permitted to have duplicate id's, but you may have duplicate name's
Radio buttons, for example, use the name attribute to link to each other, and the Razor Pages C# web framework merges elements with the same name into a list of values on the backend side
I believe flask's WTForms does it similarly
it needs to have a name to be added to the URL/GET method right?
So... I have a CRAZY idea but I'm having trouble installing everything to make it work.
Python + (some sort of backend web server framework) + QtWebEngine + Brython...
Hey, I don't know if this is the right place to ask, but can someone help me on this? I have some software I'll be coding with Django, and I want to host that software on a server and rent it out to people on a month-by-month subscription. So software as a service basically. What I'm wondering is what e-commerce platform I should use for this. I know there's platforms like WagTail, but it seems like a huge waste of time to re-invent the wheel and build a website from scratch using wagtail. It seems easier to just build a site to handle the account registration/subscriptions with something like Wix/Shopify, and then use an API in Python to authenticate through those services and confirm the subscription is valid.
I've been googling this for weeks and am stumped. Can anybody point me in the right direction?
I'd be surprised if AWS didn't have something to help with that, but a) it might be pretty complex, and aimed for larger businesses; b) I have no idea which of the eleventy bazillion of their products it would be

i have a refresh token that expires each 24 hours and an access token that expires each 5 minutes
confused what to do with it.
Problem could be solved if i use a separate database to store both of them , but some says then what's the point of api
So, the tokens give access to your own api?
the trick part is i need to keep updating them at regular intervals, if i use .env or store with in the running instance there is a chance for the bot failing all together if the code by chance restarts
yeah
Okay, we use a way of authenticating the bot to the API that has a longer lifetime
more similar to how Discord lets bots authenticate
the website exposes the api , it deals with my main database.
i use rest. so i can set the refresh token to never expire ?
How you can do that probably depends on the back-end you're using. We're using Django REST Framwork for our API.
I am too
Django, API, REST, Authentication
Using flask. How would I go on about making a todo app with subtasks? Example:
Take out the trash // maintask
Plastic // subtask
Recyclabels // subtask
make a table task
and a table subtask
and relation ship 1 to many between then
many subtasks per one task
Thanks!
👌
Is it a bad idea to nest functions in your route to make the code cleaner?
Or is there a betteer way to make your routes function cleaner?
Using flask btw
It's not really a question for how to
So I don't have any code for it right now
But if I do. Do I still separate stuff with functions and if so where do I put the functions?
@vagrant adder
it depends what kind of functions we are talking
Let's say I want to do something with one set of users. DO I put the code part in a function?
@main.route("/")
def index():
data = do_something(something)
posts = Post.query.all()
return render_template("main.html", data=data, posts=posts)
this is accepted
I was thinking something like:
@app.route("/")
def index():
def do_somthing(user):
user.status = new_status
user.mood = new_mood
return render_template("main.html", data=data, posts=posts)
If that makes any sense
@ashen trench store it in environment variables
how can I do into html / css / js ?
What do you use to host a Python API? Can I use nginx? Any recommendation?
I used nginx/pm2 to host a flask app for a year until I moved the app codebase to TS/node for front/backend code continuity
Gunicorn + nginx is a good combo
Hi
I am currently learning Django
Can anybody suggest me any Django projects for beginner or to get started
Hi. I am learning flask (and still quite new to programming and to python).
I added a feature to one of my projects: a admin can upload a file, the file will be validated and cleaned, then sent to be processed. This process take quite a long time (from a few minutes to a couple of hours). I would like to 1/ let the function run in the background 2/ make it possible for the user to follow the progress of the function.
When I google around, most people suggest using Celery (or Redis). I don't want to use that for this particular project, as it's only for a specific function, that only the admin can start, and that should be used only like once a month. It looks to me that opening a new thread should be the best option, but I can't find good guide or example. Could anyone point me to a direction?
I was thinking maybe using asyncio, but my head hurts
(to be more specific, the file will contain a large list of items (json, xml, csv), and the process will fetch additional data using various api or scraping. It takes a lot of time, but shouldn't be a problem to follow the progress.... like "now fetching infos for item 1 on 780", etc.)
@vagrant adder do you need nginx if you're already using gunicorn? 🤔 I mean are those 2 not solving the same problems?
Do I need to learn JavaScript for Django ????
@solar hatch if you're doing front-side stuff, then probably, at least the basics
depends on what you're working on really, but you can definitely create a JS-less django app without problems
i built this website in django without js
https://rohanjnr.pythonanywhere.com
@solar hatch
Ok
is there a tool I can use to build a mobile UI so I don't have to write the CSS/HTML that I can than use with my webserver running python and Flask for the routes?
guys, having a little problem with html and css
my elements are not positioning right, i guess i'm putting it wrong in html setting divs
hey guys, i'm new at html + css and i'm having a little problem on positioning blocks on my page, i mean, i end up achieving, but the margins are all unequal
i create a div called box, then i set width and height. this would be the main frame, holding everything inside it, but when i create another div, let's name box-left and another named box right, they both should be side to side, i put it inside like :
< div class="box">
<div class="box-left">
</div>
<div class="box-right">
</div>
</div>
consider that the box right have a float to be at right
when i continue adding elements, they start to be crazy
@wild thunder use flex for layouts. And divs are display block so it'll be vertically aligned. You need to use span or display inline for having elements aligned horizontally. But really, if you do not have IE requirement, use flex for everything. (Kinda)
@signal karma thanks bro, i'll study it!
Hey, I have a question regarding environments utilizing both Django and React. Pycharm and Webstorm have their own features for each respective language/framework... how do other people approach this? Do you simply have both programs sharing the same directory? Thanks.
I presonally use VSCode for everything, not sure what PyCharm is adding to Python that VSCode can't do. 🤔
Hey, I don't know if this is the right place to ask, but can someone help me on this? I have some software I'll be coding with Django, and I want to host that software on a server and rent it out to people on a month-by-month subscription. So software as a service basically. What I'm wondering is what e-commerce platform I should use for this. I know there's platforms like WagTail, but it seems like a huge waste of time to re-invent the wheel and build a website from scratch using wagtail. It seems easier to just build a site to handle the account registration/subscriptions with something like Wix/Shopify, and then use an API in Python to authenticate through those services and confirm the subscription is valid.
I've been googling this for weeks and am stumped. Can anybody point me in the right direction?
@native tide I think you asked this before. I'd expect AWS to have something.
Sorry it sunk other under answers and I couldn’t find it so I didn’t know if it got answered
@quasi ridge
Looks like they do have SaaS servers but it doesn’t allow you to do it through your own website, it’s meant for large businesses it seems
Change the response headers according to the filetype you wanna serve
Hey, not sure if this is the place to post, but I'm a 24 yr old guy who has been on computers since I was 4 years old. Its been my dream to program, but I am only just getting into it now, juggling a fulltime job. I have 10 hours free when I come home, (I'm always on the comp.)
Web Development looks fun for now, but is there anywhere I could start to expect some sort of income, of course it won't come right away, but what would be my best bet, I could post services etc, looking to quit my job soon, depression/anxiety is killing me
Thanks all ❤️
I love Python btw if that could helo
I also know it depends on your ideas etc, but I could offer a service building custom themes or something
hey guys
i'm having a little problem with flex
could someone give me a hint
please check those 2 blocks with 01 and 02 content
i'm using flex in the white frame behind them
to put them both side to side
but they keep going one over another
They can't go over each other unless you're using a transform: translate, negative margins, or position: to make them do so. But if you haven't specified margins they could be just shoved right against each other
<div class="structure">
<section id="estrutura">
<article class="main-info"> 01 </article> <!-- the bigger block should be left -->
<article class="user-on"> 02 </article> <!-- the bigger block should be right -->
</section>
</div>
If you have a third element in the flexbox it could conceivably look like that
this is the html
hm. K
i`ll take the css part
one sec
i`m 3 days on css+html
still shitty code
can i send all the CSS code?
it's not too big
!paste
Pasting large amounts of code
If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pydis.com/
After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.
position: absolute;
That's on both main-info and user-on
And as far as I can tell, doesn't need to be on anything here
but if i put relative, they become a line
Isn't that what you're going for?
no, i want them to ocupate 12%
it's not accepting percentage as height
i want these 2 blocks to be 2 containers
the idea is ok
% height is relative to the height of the parent element, or the nearest one without height: auto
But here, you've not specified height on anything
so it goes all the way up to the body tag, and that also has height auto
so it doesn't set the height
If you're aiming for something that's not going to scroll, you can set the body+html tags to height: 100%, and that would work. Or, you could use vh as your unit, which means "percent of height of browser window"
.main-info { /* Inside Structure */
width: 78%;
height: 13%;
margin: 1%;
background-color: rgb(197, 197, 197);
border: 1px solid black;
order: 1;
}
.user-on { /* Inside Structure */
width: 21%;
height: 13%;
margin: 1%;
margin-left: 0%;
background-color: rgb(197, 197, 197);
border: 1px solid black;
order: 2;
}
they have heigth, based on the ".structure"
Which has an auto height, so it keeps looking upwards
which then makes it 13%, of 96%, of the body? Which is still auto
stills the same
how can i make these 2 boxes become 13% of structure?
that is the white frame
?
<section id="estrutura"> needs a height: 100%
👍
i was like 1 hour trying to figure it out
I'm just sorry I missed that detail in the beginning ;-;
I have a question, which I think fits here.
Does anyone know a Python alternative to this?
https://www.npmjs.com/package/html-to-text
BeautifulSoup
Did you look at its example bast?
Yes
Mmm
get_text() is similar, but I'm not sure if something exists that does lists and/or alignment
hey bast, are you fullstack or do you have a preference?
fullstack
cool
i'm studying html + css to make some relation with python
i was trying to study django
but it was not making any sense to me
the views + urls
i was not getting
Well, I work with django, so I'm sure I can answer any of your questions related to that :P
views + urls are separate concepts/details
a view is a python function that constructs a response to send to the browser, a url is a route or path, for example, "https://mysite.com/asdf/123/blog-post"
the asdf/{id for post}/blog-post-title is the route/url--anything that comes in and matches it will be sent to a specific view function, which then does the responding
okay
it's making more sense now, even why i'm in html, the urls section is "equivalent" to put an "href" in a page?
Yes, pretty much
<a href=""></a>
nice, now i'm making connections
hahaha
but i'll try to create this little interface, then i go back to djano
django*
to create a little system
good luck!
thank you!
and hey
am i allowed to add you?
or comments are closed to the discord group?
i see here you have a "helper" tag, then i should respect if you can't
I prefer to keep my friends list small, so sorry
But I'll be around, and I check this channel fairly often
that's ok, i understand
anyway, thank you for helping!
i'll probably look for your again soon hahah :PPP
In Django is doing Q(a=True, b=True) equivalent to Q(a=True) & Q(b=True)?
Yes, iirc it defaults to AND
Thanks
Is this just not documented anywhere 🙄
The documentation on the Q object is fairly poor as far as I can see
I had to check the source code ;-;
there is a lot more to it than the docs
use dir
django docs is not the best at queries
@native root What is builtin? https://discordapp.com/channels/267624335836053506/366673702533988363/657284854597025802
Built into bs4, I meant
.get_text(), which lets you specify a tag separator and gives you the page’s text
Aha
@native root are you there?
i'm with this little issue
in the name of each block
i put an :hover
but this is happening
its covering the entire "line"

it's kinda funny
Hello guys! I got into Python for automating some of the office jobs I had. I'm liking it more each day and have a new dream now, to be a web developer.
Can someone guide me if I'm doing it right/missing something?
My path is HTML -> CSS -> JS basics -> PHP/Laravel framework AND Python/Django
I already know HTML, CSS and Python to make webscrapers/calculators/small scripts
You can probably skip php/laravel and jump into flask or Django
The only real reason to learn php is if you need it for a job
i'd go with c# it's really popular nowadays
NodeJS+A front end JS framework is a great way to go - thats pretty much the most popular modern web stack
Although pure-python for backend web dev, or python+a JS framework is also pretty common (at least I think it is)
Where can I learn web development with Python
Udemy, Django documentation. W3Schools if you don't already know HTML/CSS/JavaScript
Flask mega tutorial
!resources has a few links
The Resources page on our website contains a list of hand-selected learning resources that we regularly recommend to both beginners and experts.
corey schafer also has excellent tutorial series on youtube

flask keeps showing a 404

anyone know why this is happening
nvm
apparently clearing cache fixed it
Is it a good idea to use model methods or whatever they're called with flask-sqlalchemy?
(like this)
class User(db.Model):
__tablename__ = 'user'
user_id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(30), nullable=False)
created_at = db.Column(db.DateTime, nullable=False, server_default=db.text("CURRENT_TIMESTAMP"))
updated_at = db.Column(db.DateTime, nullable=False, server_default=db.text("CURRENT_TIMESTAMP"))
def __init__(self, name):
self.name = name
@classmethod
def create(cls, **kw):
obj = cls(**kw)
db.session.add(obj)
db.session.commit()```
I currently have the following code to hold static images: @app.route('/avatars/<path:filename>') def get_avatar(filename): return send_file("static\\img\\" + filename, mimetype='image')
I want to try and add a way for the size to be changeable for example like this: {{ url_for('get_avatar', filename='d.jpg', width=100, height=100) }} So something like /avatars/d.jpg?width=100,height=100 (Example)
Is there any way I can accomplish this? Help is appreciated! Thanks!
@hollow glacier don't do that
delete __init__ and create function
that init method is already done under the hood
and create() way of instancing is not preferred for flask-sqlalchemy
just do
user = User()
db.session.add(user)
db.session.commit()
if you do print(use.name) you get its name
Hey guys im using a bootstrap 4 template
and one of my js plugins dont seem to be working at all
its a smooth-scroll.js file
<a href="#faq" data-toggle="smooth-scroll" data-offset="0">FAQ</a>
using it is like that
but it wont work at all
<script src="{{url_for('static', filename='js/smooth-scroll.js')}}"></script>
i made sure to add the script like that
and there were no errors in flask when it was loaded
it was a 200 request
hey guys, anybody knows how to make php based games?
like this one https://www.meteorus.com.br/
is API if i make a script with bs4 and requests and gets me back data i want form website?
Hey if I have the following models in Django:
class Client:
type = "?"
#...
class Business:
#...
class Person:
#...
How do I represent a one-to-one relationship between Client and Business/Person with the foreign key stored in the Client model?
create a OneToOneField in the Client
Is Node JS a framework similiar to Django and Flask
A client can only be a Business or a Person.
I want to do something like:
class Client:
person = OneToOne("Business or Person")
class NaturalPerson:
# ...
pass
class PhysicalPerson:
# ...
pass
Currently I have something like:
class Client:
is_natural_person = Boolean()
is_juridical_person = Boolean()
def get_person(self):
if self.is_natural_person:
return NaturalPerson.objects.get(client=self)
return JuridicalPerson.objects.get(client=self)
class NaturalPerson:
client = ForeignKey(Client)
class JuridicalPerson:
client = ForeignKey(Client)
But it feels like there is a better way to do it.
I get this error:
sqlalchemy.exc.IntegrityError: (sqlite3.IntegrityError) CHECK constraint failed: user
[SQL: UPDATE user SET grade=?, complete_registeration=? WHERE user.id = ?]
[parameters: ('Junior', 2, 1)]
(Background on this error at: http://sqlalche.me/e/gkpj)
Here is my code idk why it is causing it:
user.set_complete_registeration(2)
db.session.add(user)
db.session.commit()```
Does anyone possibly know how to fix?
@native tide Node is just a JavaScript runtime... Express, a Node JS framework, is what would be similiar to Flask. Django on the other hand is a batteries included web framework which already implements most of the stuff that you could need out of box (authentication etc.).
ooh nice. So the website i build with Flask, I can build with Node JS too? replacing Flask with Node JS
You can replace a node api with a flask api
You could built a react frontend and connect to any of those two
I see you're already going with Django, just stick to it, it's great for learning and can built solid products
nah i'll stick with Flask
thx for the info
wait where did my message go
@here Has anyone deployed a Django or Flask backend with a React front end app, to production?
@lone cave yes , whats the deal ?
@native tide Any pain points or things you would have done differently?
@lone cave what do you mean ?
@native tide as you were developing it, were there any aspects of using those frameworks together, a pain in the ass? If you were to develop another app with those tools, what would you do differently?
@lone cave yes, start from mobile layout first.
Hi everyone
I'm new to the python world
I'd like to create a rest API, and vue as the front end
I'm a bit lost on the options... should I go with Flask or FastAPI ?
There seems to be minimal amount of info regarding a rest api with Flask, the first google hit is an article from 2013
Coming from the PHP world with Laravel, the python web dev world seems much smaller or difficult to find good resources 🤔
i would say take a look at flask, docs and community forums are great
it's extremely easy to piece an api with both of them
i have been fiddling with flask about a year now and i can say i am glad i took flask
iirc @gleaming herald did some fastapi stuff, i think he can help you out if you get stuck with fastapi
Cool
What resources did you use to build a rest api with just flask ?
because the flask mega tutorial shows a lot more than just a rest api
And isn't very tailored towards making a rest api, more like a backend-heavy app
mega flask is a good tutorial if you are building a corporate website
its huge lol
i followed corey schafer's flask tutorial series to get to know flask
after that it just comes to a lot of googling
The problem with FastAPI is that one guy has like 600 commits and then the others have like 10 commits
Same thing with Starlette
So I'm like ok.... if that guy isnt interested anymore I acquired all this knowledge for a dead framework
not sure about that
also forgot to mention
there are 2/3 ways to build a rest api with flask
- old school way
- fiddling with a lot of request arguments and
if request.method == "POST":stuff
- flask-restful
-make models and resources and let the flask-restful do the routing and other heavy lifting
3)flask-restless
- basically cheating but not a lot of customization available
And flask-restplus ?
technically the same thing as restless
abstracting your models behind the Resource object
same thing done twice
with oauth just a tad
jwt is on my bucket list
never had to write jwt systems cuz i've been doing just static websites without any particular frontend framework
What about django ?
django-rest-framework
Community is booming looks like
My bad I'm a bit lost with all the options lol
@native tide Flask is very minimal, you gotta use plugins to get all the features that Django has built in. Flask is a easier to learn and bring up, Django has quite a learning curve. If you're looking for fine control, I would look more into flask, otherwise check out Django.
This is a good article on the topic, which is the author is pretty neutral on: https://testdriven.io/blog/django-vs-flask/
Thanks for the article
@lone cave, it cleared up a couple things for me
Do you think this is still a good starting point ?
Even if it was written in 2013
I just can't wrap my head around the fact that the most comprehensive thing I've found was written in 2013
How can python and flask be so popular yet so weird to find info for ?
@native tide Haha yeah I hear ya. I think people tend to associate web development with JavaScript these days. Python is great for backend though, my team at work has Python running a server-less architecture on AWS (Lambda) right now. Yeah the author of the article you posted (Miguel) is great, he's pretty well known in the Python community.
I would take it a step further and use Gunicorn as the web server (super easy to bake in) . Also once you get through some basic projects, check out: https://github.com/zalando/connexion
Keep in mind, Python is almost 30 years old, don't worry too much if articles seem a little old. Medium is a good source for technical articles as well.
@lone cave you think people favor node over python ? I'm not a fan of the npm ecosystem
The number of dependencies for anything is staggering
Though I use Vue on the frontend
That I enjoy
I want to do a rest api with python as the backend and vue as the frontend
Thing is I'm 21 and I wanted to pick a new language, I've been using PHP for a while but a friend told me it could actually hurt my resume to know it lol
Because of the negative bias it has
I already know Vue
So my plan was to learn Python as my backend language, and then Typescript for the javascript side of things
Should be pretty set with those skills
@native tide If you already know JavaScript pretty well, I would just use it for the whole stack (Ex: Node, Vue, Express and whatever DBs). If you're looking to learn a new language and you don't know a statically typed language, check out Golang!
Ohh okay, cool. Then yeah, can't go wrong with Python!
@native tide why Vue?
@last light shipped by default with Laravel and pleasant to work with
I'm open to learning react in the future if needed but for now I just want to move on as quickly as possible to Python and Typescript
And Vue 3 is coming out soon which will bring support for Typescript
In montreal there are quite a few typescript jobs
Apart from that
The reason I went with Laravel first is cause the tooling is so amazing
With Laravel Mix you don't have to learn webpack, you just pass it a couple options and it compiles the libraries you want, with postCSS (minify, remove unused css, etc.)
