@upbeat forge you use as_view when dealing with Class Based Views (CBVs)

#

im guessing you would want a ListView and a DetailView?

upbeat forge Jan 5, 2019, 10:56 PM

#

Yes

#

List of images, I want to be able to click it and then its gonna display it in my screen with a comment

#

ListView and DetailView?

#

Thats all?

#

Oh

then you would just make a normal list view and a normal detail view in a function based view

well, you could use primary keys, but u could also use slugs

Is slugs better?

grand badge Jan 5, 2019, 11:00 PM

no, but it depends on your needs

Primary key is a number, slug is a string

Aight boys I'm back with another question. I'm using Django and DRF and the AllowPUTAsCreateMixin to PUT some data, but for some reason some of the PUTs return 400 and I can't tell why. Below are some example request.data and the responses for them.
Creates just fine:

<QueryDict: {'hero_name': ['Diablo'], 'name': ['Debilitating Flames'], 'description': ['Enemy Heroes hit by Fire Stomp are Slowed by'], 'tier': ['16'], 'order_position': ['2'], 'games
': ['1883'], 'popularity': ['14.8'], 'winrate': ['49.0']}>
web      | [06/Jan/2019 14:31:57] "PUT /api/talents/Debilitating%20Flames/ HTTP/1.1" 201 191

Fails:

<QueryDict: {'hero_name': ['Diablo'], 'name': ['Domination'], 'description': ['Casting Overpower resets the cooldown of Shadow Charge.'], 'tier': ['16'], 'order_position': ['1'], 'gam
es': ['9573'], 'popularity': ['75.2'], 'winrate': ['52.7']}>
web      | Bad Request: /api/talents/Domination/
web      | [06/Jan/2019 14:31:57] "PUT /api/talents/Domination/ HTTP/1.1" 400 69

#

I have a previous version of this bot that was inserting directly to postgres and had no problems with this data, so I can't imagine it's ACTUALLY malformed data that's causing the 400 errors.

So I'm trying to create a website...
It's an online shop, to sell websites, graphics etc. on. Is there like a platform where all the payment occurs and the product automatically gets sent to the buyer, because I don't want to go through all the hassle of creating my own checkout with something like PayPal. I know Shopify does the buy-button thing, although, you have to pay for it. Are there any free alternatives ?

sturdy sapphire Jan 7, 2019, 12:40 PM

#

I do not think you can find anyone that is free @wary mantle

#

you might only think about no monthly fee

#

if there is a "no monthly fee" and "no setup fee" you would have to pay a higher Transaction fee

#

you can look at, Paypal, Amazon Payments, WePay, Stripe

#

might be many more, but im confident that the well known ones have a "free" option

HI everyone. I'm going to venture into creating a web app. I keep reading conflicting information on Flask vs Django. Can someone shine some light? What should I use?

grand badge Jan 7, 2019, 10:34 PM

#

Its based on your preference and need. They both can create the same site. Django is more of a "batteries included" framework while Flask is more of a "Get your own batteries" framework. Django has a lot of stuff built in to the framework while in Flask, you have to install some other modules. Django makes you do things "The Django way" while Flask gives people more freedom with what a person wants to do. For example, Django comes with a built in ORM but it only works with SQL databases. Flask on the other hand, is more flexible and can let you work with NoSQL databases as long as you install the correct modules for your needs. However, because Django has a lot of things built in, it can save you the stress of choosing what you need for your project. For example, if you need an ORM in your Flask application, you'll have a lot of different options to choose from. With Django on the other hand, there is no option and you just get along with the ORM they have given you. Another reason a person might choose Django is that it can save you time writing some code that you would have to write out yourself in something like Flask.

With that said, if you want to start learning web development, a lot of people would suggest Flask as its much easier to get started with. However its not that hard to learn Django either as a first framework but the majority would suggest Flask. @somber burrow

@somber burrow I'll toss in support for Django as a starter. It's been a dream for me to learn and work in. Any time I've hit a wall with "I wonder if I can do that?" the answer is "Yes, and it's in the documentation." I wish my actual web team wasn't full of PHP devs, because I'd switch us to Python just for Django.

For somereason, when I try to change image at gallery/image/1/update or create new at gallery/image/new. It doesnt allow me to do so. Text can be changed, but I wanna get at least the picture creation working. I'll send you the code later. Is it like permission thing?

Django is awesome when all it's batteries work for you.

#

But it starts to fall apart when you need something very unusual in the web world. Sometimes 3rd party libs save the day.

#

Sometimes you have to implement it on your own.

#

And sometimes it's just better to use Flask for that project.

cold rampart Jan 9, 2019, 3:09 AM

#

So I've been looking at Responder ( https://python-responder.org/ ) and Starlette ( https://www.starlette.io/ ), the project Responder is based on, and I really tried but couldn't see the advantages of using Responder vs. Starlette.

Starlette

The little ASGI library that shines.

#

Or is it really just the API? I feel like Responder is just boilerplate on top of Starlette to make Starlette easier to use. Am I missing something?

cold rampart Jan 9, 2019, 7:45 PM

I guess Responder has a lot of useful abstractions on top of Starlette

assuming creator is a User, could you not just put the model reference in quotes there under themes and not worry about the import where the model User lives?

And

That didn't work either

#

    themes = models.ManyToManyField('Theme', blank=True, related_name="themes", default=Theme.built_ins)

#

Bare in mind the built_ins is a classmethod

#

so it is a callable

Maybe use signals, but in one you'd at least have to import from the app. However, you wouldn't have the model files importing

those are in views.py
address_processor.py needs those two values to run its script.

in address_processor.py would i just from .views import form?

which all makes sense but then how do i get that info out of address_processor.py into views

using pixel unit works fine. But rem is not working.

#

Oh.. okay

#

really dumb mistake. I just realized that space should not be left between the numeric value and the word "rem"

Now it is working as expected.

Might be a little off-topic, but does anyone well-versed in Javascript want to code review a tip calculator I've coded out? Basically implementing the use of objects, their properties, and functions
@ me if you're available please!

#

hey, i’m a beginner looking to dive into web dev and i’m just wondering if anyone has any experience with django and vuejs. does anyone know if they work well together?

#

or does it not matter what i use for client side

candid basalt Jan 17, 2019, 8:51 AM

#

The latter.

#

If you are looking into SPA or just heavily AJAXed apps - check Django REST Framework.

#

Otherwise it's regular Django templates either way.

meager pewter Jan 17, 2019, 8:56 AM

#

sorry, im a beginner, could you explain spa and ajax?

#

isnt ajax javascript

#

but is it possible to implement vue js with django

#

@candid basalt

candid basalt Jan 17, 2019, 9:07 AM

#

SPA = single page application.

#

I.e. if website page does not fully reload once you click around.

#

Just parst of it.

#

AJAX is a JavaScript technology, yes.

#

It allows you to send requests and update data on the page dynamically without reloading the page itself.

#

Yes, it's possible to use vue.js with django.

meager pewter Jan 17, 2019, 9:11 AM

#

ah okay

#

ajax sounds interesting

#

so you can implement things like live feeds or something like that

#

silly question, is rest like vue?

#

@candid basalt

candid basalt Jan 17, 2019, 9:28 AM

#

Vue is client side framework.

#

Rest is server side.

#

These are 2 different technologies that serve different purposes and should work together.

meager pewter Jan 17, 2019, 9:28 AM

#

ahh ok

candid basalt Jan 17, 2019, 9:28 AM

#

I would recommend you to start with regular approach such as django templates.

meager pewter Jan 17, 2019, 9:29 AM

#

ok

candid basalt Jan 17, 2019, 9:29 AM

#

And once you are comfortable with it - go for javascript, vue. ajax etc.

meager pewter Jan 17, 2019, 9:29 AM

#

are django templates like bootstrop

#

boostrap

candid basalt Jan 17, 2019, 9:29 AM

#

Not quite. It's again different things that should work together.

#

Django templates are server side, bootstrap is client side.

meager pewter Jan 17, 2019, 9:30 AM

#

oh

#

what can we achieve with a django template

#

are they like prewritten pieces of code for something like a user registration and login page

candid basalt Jan 17, 2019, 9:30 AM

#

You may want to ask google about that. It's a very broad question and discord chat won't be enough to describe.

meager pewter Jan 17, 2019, 9:31 AM

#

ah okay all g thanks

#

another question @candid basalt, whats the relation between rest and django? is it like vue js to js

candid basalt Jan 17, 2019, 9:40 AM

#

Rest Framework is a framework built on top of Django Framework.

#

It's an extension tha allows to build APIs promptly.

meager pewter Jan 17, 2019, 9:40 AM

#

ah

#

would it be useful to beginners?

#

like what are the extra features compared to normal django and would a beginner need them

meager pewter Jan 17, 2019, 10:33 AM

#

@candid basalt

candid basalt Jan 17, 2019, 10:34 AM

#

REST? No, I don't think so.

#

Django itself is more then enough.

meager pewter Jan 17, 2019, 10:50 AM

#

ah okay

#

theres a big sale on udemy and im wondering if i should pick up that rest and flask course

pine plover Jan 17, 2019, 2:42 PM

Hey. I'm trying to display all webhooks in a specific guild using Flask in a website.

@app.route('/', methods=['GET', 'POST'])
def index():
    ENDPOINT = "/guilds/525724489129000970/webhooks"
    URL = "https://discordapp.com/api/v6" + ENDPOINT
    res = requests.get(URL,
                       headers={"Authorization": "Bot <censored>"})
    r = res.json()
    for _ in r:
        flask.render_template("index.html", webhooks=f"<option>{_['name']}</option>\n")
    return flask.render_template("index.html")

This is the code I've tried and it didn't work.

ivory crest Jan 17, 2019, 3:52 PM

#

You should pass 'r' through your webhooks context into the template then iterate through the data in the template to display.

If you're doing some kind of form with those options and using wtforms you can use a dynamic query to fill in the options as well under the form code instead of the view.

#

@pine plover

pine plover Jan 17, 2019, 3:54 PM

#

Can you give me an example?

ivory crest Jan 17, 2019, 3:55 PM

#

return render_template("index.html", webhooks=r)

#

Then use jinja2 template engine for your for loop on r inside index.html

#

{% for item in r %}
<option>item['name']</option>
{% endfor %}

#

http://jinja.pocoo.org/docs/2.10/templates/

pine plover Jan 17, 2019, 4:00 PM

#

Oh okay, I got it now

#

    {% for _ in r %}
    <option>{{ _.name }}</option>
    {% endfor %}

This thingy is inside the select tag

Hey guys, so I built this : https://easydryclean.be/beta/index
And I would like to add some features like user authentification, a dashboard, job listings, a recommandation system. I'm wondering as I started a CS degree, I started to learn python so this is why I'm considering django. But here is main question : would it require to recode everything to make the back-end work on my current website? (I used mainly html/css and some js scripts for scroll effect and php for the contact forms). Is django the right solution in my case ?
Ik that might seems a dumb question, I just never had to deal with back-end and db, first time I'm trying to build something like that

gritty locust Jan 17, 2019, 4:41 PM

#

Hello guys
Does anyone have some knowledge on creating Websocket API's? I need some help to connect to one.

ivory crest Jan 17, 2019, 4:46 PM

#

@pine plover sorry got distracted with work, I'm not sure what your goal is without an explanation or seeing the current code.

@deft needle fundamentally a web site is a document using html, pictures, styling to make it look nice. Adding in Javascript to make it interactive and dynamic like an application. These are all client side operations; you create a template to design that interactive document for the client.

The backend like Django, flask, bottle, pyramid, etc. handle the server side (backend) data. An example would be selecting a table from a database and filtering the desired rows then sending it to the template to manipulate it in a pretty fashion.

#

@gritty locust which framework?

pine plover Jan 17, 2019, 4:47 PM

#

Hey

#

https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_select

#

This is what i mean with select tag

ivory crest Jan 17, 2019, 4:48 PM

#

I know what the select tag is I'm just not understanding what you mean by accessing it? Do you mean adding the value? From client side interaction? After posting it?

pine plover Jan 17, 2019, 4:49 PM

#

Getting the value

#

For example I got this in my select tag: Apple, Banana

#

And I selected Apple

gritty locust Jan 17, 2019, 4:49 PM

#

Hello @ivory crest < I have tried with some standard libraries but without success, for exemple, I'm trying to connect to this link: wss://olymptrade.com/ws2
But I just get a handshake error, 404.

pine plover Jan 17, 2019, 4:49 PM

#

after I click on submit it displays "Apple" because I selected it

ivory crest Jan 17, 2019, 4:50 PM

#

{% for _ in r %}
<option value="{{ _.name }}" >{{ _.name }}</option>
{% endfor %}

#

So you're asking how to access it from inside the view

#

After post

pine plover Jan 17, 2019, 4:52 PM

#

Ugh, never mind

deft needle Jan 17, 2019, 4:52 PM

#

@ivory crest Hmm, so like, I could keep what I currently have and add smth to manage the data that the user is gonna fill in on the client side and send them to the server side and handle these data using Django for example ?

ivory crest Jan 17, 2019, 4:53 PM

#

@pine plover sorry man but the question is vague and can be interrupted in different ways

ask

Asking good questions will yield a much higher chance of a quick response:

• Don't ask to ask your question, just go ahead and tell us your problem.
• Try to solve the problem on your own first, we're not going to write code for you.
• 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.

@native tide you can probably just save the headache entirely by not using apache. nginx would be better. if you want really easy, you can use Caddy. configuration to proxy to a flask app is a single line

@dull ginkgo technically, setting the servers host to '0.0.0.0' instead of 'localhost' or '127.0.0.1' is what makes it visible externally.

guys i have a question.

#

im currently making a program that informs me with a mail when a new post releases from the site i follow.

#

i created a html design so it would look like better compared to plain text only

#

this is what i created

📎 test-2.jpg

#

please dont focus on the language/colors/pictures for now

#

but when i run the program and it sends me mail, this is what i get

📎 test-7.jpg

#

the problem is not the texts/colors etc. dont focus on that (i get the values from the site, like title,picture, date etc)

#

📎 test-1.png

#

here i tried to explain what i want to do. you can see the difference between two design. my question is, what causes that? and how can i fix it? i assume its something about css. i can share the code if required. the main program is written in python but this has nothing to do with python i guess

#

here is the source code: https://paste.ubuntu.com/p/ZNj8tKdVBS/

#

the css and html mixed together and im sorry for that. the css does not work if its written in another file and called via code (as far as i know, i tried before and it didnt work. but i would be happy if there is a way to do so). so im sorry if the code looks confusing

yeah, those aren't really used in general much anymore these days. on any os. they are not the best

writing html/css yourself is not a great option? i ask because even pigendo and such are essentially just themin gbootstrap for you

they arent that versatile and you can theme bootstrap without them

also what do you mean about the highlight? you want the link color or the hover color or what

steel tiger Jan 20, 2019, 11:41 PM

#

link color

#

i think theres somewhere in the css i edited manually once

junior cloak Jan 20, 2019, 11:42 PM

#

you dont know how to write the css to change the link color, or you want to find out what that link color is?

#

also link color is one of those things easy to override with the bootstrap themer

#

doing tons of one-off overrides is problematic

steel tiger Jan 20, 2019, 11:43 PM

#

yeah

#

@grand badge thanks, would this be enough or do I need to read some books

#

?

grand badge Jan 21, 2019, 6:40 PM

#

i think it would be enough to get the basics down

#

volcyy also suggested the official tutorial by django docs which is good for starting too

wanton cave Jan 21, 2019, 9:24 PM

#

Hi! I started learning django and I am familiar with most of basics already... Looking for good resources for learning django-material , preferably articles with step-by-step examples, videos are also fine. Can anyone reccommend something?

grand badge Jan 21, 2019, 9:43 PM

#

@wanton cave i sent a yt playlist up there

#

its good

wanton cave Jan 21, 2019, 9:44 PM

#

@grand badge How can I find it?

#

I am new to discord, I would prefer not to scroll up into oblivion 😃

#

Is it pinned?

brave mantle Jan 21, 2019, 9:45 PM

#

It's not that far lol

grand badge Jan 21, 2019, 9:45 PM

#

uhm i sent it a few messages before

#

you said you're into articles, django docs have a good beginner friendly tutorial

wanton cave Jan 21, 2019, 9:49 PM

#

Yeah, right... But I was looking for django-material specific stuff 😃

brave mantle Jan 21, 2019, 9:49 PM

#

And that it is

wanton cave Jan 21, 2019, 9:52 PM

#

how is that? Looks like 'vanilla' django

brave mantle Jan 21, 2019, 9:52 PM

#

Oh, you're talking about some extension

#

Well do you know how to use Django already?

#

Because you should start with that.

wanton cave Jan 21, 2019, 9:54 PM

#

Yeah... I am familiar with basic concepts. I did few tutorials like that already

#

That's the whole point

pine plover Jan 21, 2019, 11:04 PM

Heyoo, someone here who can help me?

!ask

lavish prismBOT Jan 21, 2019, 11:04 PM

#

ask

Asking good questions will yield a much higher chance of a quick response:

• Don't ask to ask your question, just go ahead and tell us your problem.
• Try to solve the problem on your own first, we're not going to write code for you.
• 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.

    member_names.append(member["user"]["username"])

#

And this is not working

#

I'm getting an internal server error

brave mantle Jan 21, 2019, 11:05 PM

#

Traceback?

pine plover Jan 21, 2019, 11:05 PM

#

Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

brave mantle Jan 21, 2019, 11:05 PM

#

That's not a traceback

#

Look at the console of your webapp

pine plover Jan 21, 2019, 11:06 PM

#

no error

brave mantle Jan 21, 2019, 11:06 PM

#

I mean, either there is an error or there isn't

#

You're checking the window you started it in, right?

pine plover Jan 21, 2019, 11:06 PM

#

No

#

Mate, I'm not getting an error

brave mantle Jan 21, 2019, 11:07 PM

#

What webapp framework are you using?

pine plover Jan 21, 2019, 11:07 PM

#

Flask

#

How do I iterate over lists in jinja?

brave mantle Jan 21, 2019, 11:07 PM

#

And how are you running it?

pine plover Jan 21, 2019, 11:07 PM

#

app.run()

brave mantle Jan 21, 2019, 11:07 PM

#

Rather than the flask CLI? Okay

#

There should definitely be some kind of output when that happens

#

Also, that is indeed how you iterate over a list in jinja

pine plover Jan 21, 2019, 11:08 PM

#

Ok

#

Thanks

brave mantle Jan 21, 2019, 11:08 PM

#

If you're getting an exception and Flask isn't outputting it, you might want to enable debug mode

#

http://flask.pocoo.org/docs/1.0/quickstart/#debug-mode

#

also, http://flask.pocoo.org/docs/1.0/errorhandling/#application-errors

pine plover Jan 21, 2019, 11:10 PM

#

I'm running this in a thread

#

So, not possible

brave mantle Jan 21, 2019, 11:10 PM

#

oh, well that's probably why you get no output

#

Why are you doing that?

pine plover Jan 21, 2019, 11:11 PM

#

I'm running my bot and the website

brave mantle Jan 21, 2019, 11:11 PM

#

You should use aiohttp instead.

#

Or even better, run them separately

pine plover Jan 21, 2019, 11:11 PM

#

Lemme just run in separately

brave mantle Jan 21, 2019, 11:12 PM

#

OK, but running the site separately will give it no direct access to your bot's memory

#

What happened with the bot and site for this server is that the site exposes an API, and the bot makes use of it

Is it IP:port

coral ridge Jan 22, 2019, 12:54 PM

#

host=0.0.0.0

dull ginkgo Jan 22, 2019, 5:04 PM

#

should i use caddy next time as my web server instead of apache?

brave mantle Jan 22, 2019, 5:05 PM

#

You should use nginx

dull ginkgo Jan 22, 2019, 5:07 PM

#

nginx isnt free

brave mantle Jan 22, 2019, 5:10 PM

#

Yes it is

#

No idea where you got that from @dull ginkgo

dull ginkgo Jan 22, 2019, 5:13 PM

#

my bad, i was looking at ngnix plus

#

@brave mantle

brave mantle Jan 22, 2019, 5:13 PM

#

ah okay :P

ivory crest Jan 22, 2019, 5:59 PM

#

@jagged chasm check out ngrok

#

It's a tunnel proxy which will assign a temporary random web address reachable on the internets without sharing your up or port forwarding.

#

Free account works great and very handy for sharing the development server link with someone as a preview or collaboration.

hollow flower Jan 22, 2019, 6:05 PM

I'm using Flask, and I'm hitting my head to a wall with my json.

How would I format this better so it would have data, count: <count> & data, channel_name : <name-of-channel>?

from flask import request
from flask_restful import Resource
from model import db, Messages, MessagesSchema, Channels, ChannelsSchema
from sqlalchemy import func


class CountMessagesByChannel(Resource):
    def get(self):
        value = request.args.get('user_id')
        if value is not None:
            count = (db.session.query(func.count(Messages.message_id), Channels.channel_name)
                     .join(Channels)
                     .filter(Channels.channel_id == Messages.channel_id, Messages.user_id == value)
                     .group_by(Channels.channel_name)
                     .all())
            return {'status': 'success', 'data': count}, 200
        else:
            return {'status': 'failed', 'message': 'This is not how it works'}, 400

#

@dull ginkgo if you want to do something quick/easy, yes, use caddy!

#

@brave mantle you should look at it too, if you havent.

#

yes, nginx is better, but caddy is 80% there with 1% of the complexity

brave mantle Jan 22, 2019, 8:05 PM

#

I'd rather use nginx, it's very well tested and I already understand its intricacies

junior cloak Jan 22, 2019, 8:05 PM

#

this is the entire config you need to proxy to a python app: domain.tld { proxy / localhost:8000 { transparent } }

brave mantle Jan 22, 2019, 8:05 PM

#

I actually make super heavy use of it in my own infrastructure

#

That won't work for wsgi, will it?

junior cloak Jan 22, 2019, 8:06 PM

#

yup

#

that is for wsgi

brave mantle Jan 22, 2019, 8:06 PM

#

I suppose it would if you're using gunicorn, yeah

junior cloak Jan 22, 2019, 8:06 PM

#

i use it in production with gunicorn, aiohttp and uvicorn (different places of course)

#

caddy is written in Go and extremely fast, performance and concurrency comparable to nginx

#

i dont disagree with you about nginx, but in my opinion since most of these questions seem to be people super frustrated with the complexity and who just want to put the damn app on a server somewhere, it's tough to argue with caddy

#

you shouldnt have to spend a week figuring out a complicated web server just to run the app you already built

#

and from my observations in here that final step of making your new app work with a web server seems to be a big hurdle for the uninitiated

maiden plinth Jan 22, 2019, 8:11 PM

Anyone familiar with django-treebeard materialized paths and DRF? I am unable to move nodes within a serializer. It works perfectly within my classed based view. The same logic doesn't work in the serializer at run time. The tree gets corrupted. Anyone have an idea why?

junior cloak Jan 22, 2019, 8:13 PM

#

caddy can also do things like automatically set up ssl via certbot, its own rate limited, caching, etc., update dns providers with current info, handle git webhooks, etc., each of these being as simple to config as what i just posted above and requiring maybe 3-5 lines in your Caddyfile

meager anchor Jan 22, 2019, 8:35 PM

#

https is a one-time setup, and caddy is very immature compared to nginx

junior cloak Jan 22, 2019, 8:47 PM

#

it's only a few years old, yes. but it's widely used, tested, known to be performant, and used in production in huge places. nowhere near as much as nginx, sure, but it is hard to argue with being 80% there and requiring less than five minutes to set up a proxy to a python web app

#

if you arent already familiar with nginx (which describes the people in here who tend to ask) it is very daunting, ive seen folks over the course of days trying to get nginx or apache to play well with their flask app

#

and also the use-case for these things isn't usually "i need to launch a massive enterprise web app that can handle 500k rps by this week". it's usually "i just want to put my test web app on a single server instance so people can see it"

#

so although i still think caddy is a fine choice for big production apps, you definitely aren't going to need the benefits it provides over nginx in this use case

brave mantle Jan 22, 2019, 8:50 PM

#

if caddy can't do that, then it's probably a better use of your time to learn nginx, though

#

Might as well do it right the first time

junior cloak Jan 22, 2019, 8:51 PM

#

if caddy cant do what?

#

caddy does what i think most people need and performs very well, the only argument i do fully understand is that it's just not as old as nginx or as widely used and trusted

#

again, learning nginx is not a bad idea, but do you really think it makes sense to spend an hour doing the Flask tutorial but then need to spend another week figuring out server instances and then nginx config and stuff just to then have the thing be on the web?

#

if learning caddy took any time, like learning nginx, then i would agree. but it really does not

brave mantle Jan 22, 2019, 8:54 PM

#

nginx doesn't really take that much time to learn

meager anchor Jan 22, 2019, 8:54 PM

#

configuring nginx really isnt rocket science

#

there's billions of guides on the internet, the configuration format is very human, it is well-documented

#

oh, and also, i dont need to compile nginx by by myself to use it commercially

junior cloak Jan 22, 2019, 9:00 PM

#

i do think nginx is a huge learning curve for most people

#

and i also agree it's a better choice for production use. but i do think the perfect use-case is, well, most of the people who ask about it in here, who for them usually they have already been trying to figure out nginx/apache/whatever and are frustrated

#

when it comes down to it, i also don't believe one needs to be an expert in 12 other things other than python to be able to deploy a python app somewhere, but that's more of a philosophical thing, hah

#

i like heroku and container hosts because you can do exactly that -- deploy the app you built, never touch nginx config or the plethora of other things running on a linux box that are not the app you built

brave mantle Jan 22, 2019, 9:03 PM

#

Honestly we mostly just get people complaining about apache, that I've seen anyway

#

which.. fair enough, apache is a real pain

junior cloak Jan 22, 2019, 9:05 PM

#

it still isn't something you jump into in a few minutes. and it can be difficult to debug because different default configs exist on different OS package managers and such

brave mantle Jan 22, 2019, 9:06 PM

#

I've only really seen two major config setups

#

one where you put everything into /etc/nginx/sites-enabled

#

and one where you want to do that and it isn't set up for you

hollow flower Jan 22, 2019, 9:13 PM

Sorry to hijack the channel, but why I can't do this like this?

@hollow flower ignoring for the moment how silly those nested argument checks are.... what is Messages? is that a SQLAlchemy ORM model? Table object? Peewee? whatever it is, it does not think it has an insert attribute

brave mantle Jan 22, 2019, 9:21 PM

#

I thought it was session.add(Message(...))

#

It's sqlalchemy iirc

hollow flower Jan 22, 2019, 9:21 PM

#

Yes, db.Model is that Messages.

brave mantle Jan 22, 2019, 9:21 PM

#

I'm on mobile so I can't look it up

hollow flower Jan 22, 2019, 9:21 PM

#

https://docs.sqlalchemy.org/en/latest/core/tutorial.html#coretutorial-insert-expressions

junior cloak Jan 22, 2019, 9:22 PM

#

Core and ORM are not the same

brave mantle Jan 22, 2019, 9:22 PM

#

I was right

#

It's session.add

hollow flower Jan 22, 2019, 9:23 PM

#

Well, no wonder it does not work.

junior cloak Jan 22, 2019, 9:23 PM

#

well, no, the bigger issue isnt the session

#

it's that a Table from Core has an insert attribute, whereas db.Model does not

brave mantle Jan 22, 2019, 9:24 PM

#

...yes. :P

hollow flower Jan 22, 2019, 9:24 PM

#

Oooh, well that would explain that.

brave mantle Jan 22, 2019, 9:24 PM

#

But that is what he wants to be using

#

Or she

junior cloak Jan 22, 2019, 9:24 PM

#

Messages(text='whatever', somefield='something') for ORM

#

wrapped in session.add(), yes

hollow flower Jan 22, 2019, 9:24 PM

#

@brave mantle Or neither as in not a she or a he.

brave mantle Jan 22, 2019, 9:24 PM

#

Or they!

#

Anyway yes

junior cloak Jan 22, 2019, 9:25 PM

#

Core assumes you're using Table, which does have an insert() attribute and works very differently

#

@hollow flower is this flask? are you using flask-sqlalchemy?

hollow flower Jan 22, 2019, 9:25 PM

#

Yes

#

The imports:

from flask import request
from flask_restful import Resource
from model import db, Messages, MessagesSchema, Channels, ChannelsSchema
from sqlalchemy import func

junior cloak Jan 22, 2019, 9:26 PM

#

consult the flask-sqlalchemy docs then: http://flask-sqlalchemy.pocoo.org/2.3/quickstart/

#

as it works differently

#

but most importantly, SQLAlchemy has multiple completely different ways to work with databases

#

Core and ORM are not the same and cannot be used the same

hollow flower Jan 22, 2019, 9:27 PM

#

I still have no idea of what the correct way to use that is.

brave mantle Jan 22, 2019, 9:28 PM

#

It's a big project with a lot of moving parts, it takes most people a while to get used to

hollow flower Jan 22, 2019, 9:33 PM

#

Okey, I got past that error, how do I test the query without actually executing it?

#

If I want to see what it would be in SQL.

brave mantle Jan 22, 2019, 9:34 PM

#

Aren't you testing in a test environment?

#

You could turn on the sqlalchemy debug stuff so it logs all the statements

hollow flower Jan 22, 2019, 9:35 PM

#

If you mean SQLALCHEMY_ECHO it is already True.

#

And not entirely in a test enviroment.

brave mantle Jan 22, 2019, 9:36 PM

#

Don't test in production

#

Recipe for disaster

hollow flower Jan 22, 2019, 9:36 PM

#

I have a backup of the table/database.

brave mantle Jan 22, 2019, 9:36 PM

#

Don't do it

hollow flower Jan 22, 2019, 9:37 PM

#

But did you mean that one?

brave mantle Jan 22, 2019, 9:38 PM

#

Run it locally on your machine and test there

hollow flower Jan 22, 2019, 9:43 PM

#

What would be a great way to do token auth for the API endpoints?

junior cloak Jan 22, 2019, 9:45 PM

#

what kind of auth, what kind of token, etc

#

is your app the auth service or will it talk to an external auth service

#

it's easy to add a decorator to your endpoints requiring a valid auth token. the much harder thing is the rest of the tooling that assumes -- who the auth service provider is... or if it's you then how the user signed up, what kind of auth you use, how you secure/store the credentials, whether you handle access by something like sessions vs jwt, etc etc. auth can be complicated

#

@hollow flower but if it's something silly for now just like a hard-coded token you will use for yourself to restrict the api access to it, then that is easy

hollow flower Jan 22, 2019, 9:51 PM

#

Like, I need to be able to generate long lasting tokens, and revoke if needed by demand. It's a database API basically, for a few different things that need to be able to do things with the db.

junior cloak Jan 22, 2019, 9:52 PM

#

many folks will say using sessions is preferable to json web tokens because they are safer and easier for revocation

#

but you can also use tokens pretty easily still by doing something like, either storing all valid token ids in Redis, or do the inverse and just store any blacklisted/revoked tokens there

#

and just do a check on request

brave mantle Jan 22, 2019, 9:54 PM

#

If you're writing an API designed to be used programmatically by other people, API keys are probably the way to go

hollow flower Jan 22, 2019, 9:54 PM

#

That is correct.

brave mantle Jan 22, 2019, 9:55 PM

#

Because of CSRF I wouldn't recommend sessions for that then

junior cloak Jan 22, 2019, 9:55 PM

#

JWT is defintely very easy for this. hands-down

hollow flower Jan 22, 2019, 9:55 PM

#

https://blog.miguelgrinberg.com/post/restful-authentication-with-flask Is this over complicating things?

junior cloak Jan 22, 2019, 9:55 PM

#

but it's so easy that over recent years JWT has become the norm before people realized the revoking problems

brave mantle Jan 22, 2019, 9:56 PM

#

I'm not really sure of the advantages of JWT

hollow flower Jan 22, 2019, 9:57 PM

#

What would be the best approach to API keys, if not JWT?

junior cloak Jan 22, 2019, 9:57 PM

#

@brave mantle yeah what else are you thinking with the word "token" if not jwt

brave mantle Jan 22, 2019, 9:58 PM

#

I'm not, because that's an ambiguous term

#

I usually go with API keys

junior cloak Jan 22, 2019, 9:59 PM

#

@hollow flower that isnt too complex, that looks like your average user signup boilerplate, except no mention of invalidation/revocation

#

yeah but i mean arent these still all referring to a stateless token with the same drawbacks basically

brave mantle Jan 22, 2019, 10:00 PM

#

Again I don't know what those are in your mind :P

hollow flower Jan 22, 2019, 10:00 PM

#

What do you exactly mean by API keys in this context?

brave mantle Jan 22, 2019, 10:01 PM

#

They're usually just randomly generated strings associated with an account

junior cloak Jan 22, 2019, 10:01 PM

#

that's arguably worse

#

a JWT at least has to be decoded and validated and has things like the expire time baked into it

#

you can also just generate a giant random token for each api key and save that into the database, sure

#

both have drawbacks

hollow flower Jan 22, 2019, 10:04 PM

#

Import part is the possibility to easyish revoke the key if needed.

junior cloak Jan 22, 2019, 10:04 PM

#

but @hollow flower the basics of this are the same regardless. you can get started by making a decorator that you apply to your endpoints that makes sure a token was provided in the header or query string

brave mantle Jan 22, 2019, 10:04 PM

#

I have not used JWTs, hence questions

junior cloak Jan 22, 2019, 10:06 PM

#

tokens stored in the DB: benefit = pretty simple, easy to revoke by deleting it. downside = the strings dont also contain useful data like what parts of the api they are allowed to browse, an enforced expire time, etc, and laso that you need to hit your sql database on every request

#

jwt = the user's info, permissions, roles, expire time, etc. are encrypted and baked into the token string itself, so that info is there and can be validated, wont validate if it's past the expire date, and you dont need to store it in your database and slam it on each api request. downside = revocation is slightly harder, there are some security concerns

hollow flower Jan 22, 2019, 10:09 PM

#

Security conserns like?

junior cloak Jan 22, 2019, 10:09 PM

#

not as big of a deal now, but there used to be issues not unlike CSRF when using sessions

#

the bigger issue is with how lots of people use them

#

since they are stateless and dont need to be stored in the database, or kept in a cookie, that also means there is no obvious way to revoke them if you didnt set up a blacklist somewhere like i mentioned

hollow flower Jan 22, 2019, 10:11 PM

#

So you mean, blacklist like store the key in that list, and check against it on every request?

junior cloak Jan 22, 2019, 10:12 PM

#

or people would use weak keys when encrypting the JWT, which made it easier for people to hack them in order to decode, which was bad since the token also contains user data and permissions

#

@hollow flower yup. redis is perfect for this. and much much much faster/lighter than putting it in your database

#

redis will likely have responded to the token check before your sql db connection has been initiated ha

hollow flower Jan 22, 2019, 10:13 PM

#

Okey, let's say that the server whould for whatever reason lose power, would that cache also be lost?

junior cloak Jan 22, 2019, 10:14 PM

#

redis does have persistence, but by default it isn't instant or atomic like databases

#

but you can adjust it to write constantly, and also depending on your use-case the few minutes it might wait between writes may be acceptable risk

hollow flower Jan 22, 2019, 10:15 PM

#

Due to redis being completely unknown to me, I have no clue about it.

junior cloak Jan 22, 2019, 10:15 PM

#

start learning 😃

#

it's very easy

#

compared to most things

#

and beyond that, it works remarkably well at what it does. which is basically anything requiring caching or fast data retrieval

#

(and if you have a project that scales up and has lots of users and such, it's likely that your caching systems are using 10x more than the underlying databases and whatnot)

#

redis can help you do things like cache recent content, easily store lots of analytics or event data without destroying your sql database, use it to rate-limit API requests, tons more

#

but yeah for tokens it would be easier than using a database. just have a redis list called revokedtokens with all the ids. or one with currenttokens or something. redis does not require models or a schema or anything

meager anchor Jan 22, 2019, 10:33 PM

#

wouldn't you rather use a set?

hollow flower Jan 22, 2019, 10:36 PM

#

Or just use IP address restriction.

junior cloak Jan 23, 2019, 12:34 AM

#

@meager anchor haha, yes when I said "list" i was not specifically referring to the redis data structure, i just meant as a psuedocode concept of a thing that holds tokens

#

@hollow flower an ip restriction for what?

prime ridge Jan 23, 2019, 1:55 AM

#

Question to developers that frequently use both Python and Golang: What factors into your decision on whether to write an application in one language over the other?

hollow flower Jan 23, 2019, 4:09 AM

#

@junior cloak The API access restriction.

junior cloak Jan 23, 2019, 4:12 AM

#

@hollow flower I thought you wanted to use tokens for that, since that was your initial inquiry, asking the best way to implement tokens haha

#

IP restriction also doesn’t let you say “this user can access the api, but doesn’t have write access to [whatever]”

hollow flower Jan 23, 2019, 4:13 AM

#

That is not needed atm.

junior cloak Jan 23, 2019, 4:13 AM

#

Or rate limiting. But those were just some examples

#

Of things redis can do, not that you need them all, just as an idea of how powerful of a tool it is

#

It’s more vital these days to high performance apps than many realize is all

hollow flower Jan 23, 2019, 4:17 AM

#

Redis seems like overcomplicating things at this point.

#

I do have an idea, I could build a user portal where user could revoke the token. Does that sound like something I should look at more or is it just meh? Your thoughts?

#

@junior cloak

junior cloak Jan 23, 2019, 9:44 AM

#

@hollow flower well, so in redis you can make a set of valid tokens by simply adding the first one while creating the new list, with sadd activetokens 123.456.678.910

#

you check later to see if it exists with sismember activetokens 123.456.678.910 or remove it with srem activetokens 123.456.678.910

#

if you think it's easier or faster to store those in a database

#

with a schema to manage

#

and build an interface to it, then be my guest

#

you would be a wizard 😃

hollow flower Jan 23, 2019, 9:46 AM

#

I have absolutely no idea of those Resis related command/functions.

#

*redis

junior cloak Jan 23, 2019, 9:47 AM

#

i know, but i think if you spend half an hour looking into it youll see how truly easy it is

brave mantle Jan 23, 2019, 9:47 AM

#

Huh. Hey dkh, we should tell everyone to use nginx!

junior cloak Jan 23, 2019, 9:47 AM

#

and as opposed to something like a sql database, you can store millions of items at once with no problem and query them in fractions of a second

#

the speed part is vital

brave mantle Jan 23, 2019, 9:48 AM

#

I hope you see the irony

#

:P

junior cloak Jan 23, 2019, 9:48 AM

#

@brave mantle i dont actually

brave mantle Jan 23, 2019, 9:48 AM

#

A relational SQL database is definitely plenty fast for this for 99% of people

junior cloak Jan 23, 2019, 9:48 AM

#

in both/most situations i am pushing a very minimalist system

brave mantle Jan 23, 2019, 9:48 AM

#

And they're already using one, so it's one less thing to deploy as well

hollow flower Jan 23, 2019, 9:49 AM

#

Exactly

#

So stop with the Redis.

junior cloak Jan 23, 2019, 9:49 AM

#

haha

#

okay well look

#

i get that totally and i will back down on it

#

but at the same time you asked the group how we would suggest doing it

hollow flower Jan 23, 2019, 9:49 AM

#

True

junior cloak Jan 23, 2019, 9:50 AM

#

and that is how i have done it, and anyone who has had to do it on a web service that has hundreds or thousands of concurrent users these days is probably using redis for things like this

#

you are correct in that you proabbly do not need it now

hollow flower Jan 23, 2019, 9:50 AM

#

Truth to be told, I looked at the Redis docs, but didn't understand most of it

brave mantle Jan 23, 2019, 9:50 AM

#

There is a huge drawback to redis too

junior cloak Jan 23, 2019, 9:50 AM

#

it may be vital eventually

hollow flower Jan 23, 2019, 9:50 AM

#

@brave mantle Being RAM?

brave mantle Jan 23, 2019, 9:51 AM

#

Yep

#

Entire thing is in memory at all times

hollow flower Jan 23, 2019, 9:51 AM

#

Yeah, my instance lacks RAM for that kind of thing.

junior cloak Jan 23, 2019, 9:51 AM

#

i will back down on it but dont get upset because you asked for how we'd do it and you just dont like how i'd do it haha

hollow flower Jan 23, 2019, 9:52 AM

#

I'm not upset, more like annoyed.

junior cloak Jan 23, 2019, 9:52 AM

#

@brave mantle everything is loaded into memory at once in redis at all times. it does not only live in memory. it by default persist to disk every few minutes or so depending on things

#

and you can change that

brave mantle Jan 23, 2019, 9:52 AM

#

yes, I know that

junior cloak Jan 23, 2019, 9:52 AM

#

to be much more frequent, or redundant

brave mantle Jan 23, 2019, 9:52 AM

#

I use redis

#

:P

junior cloak Jan 23, 2019, 9:52 AM

#

and that's also why you store things in it like cache

brave mantle Jan 23, 2019, 9:52 AM

#

I actually wish I wasn't stuck with redis for what I'm using it for but

#

I host a nodebb forum for an org and it was decided on early that it'd use redis instead of mongodb

junior cloak Jan 23, 2019, 9:53 AM

#

but not use it as like the persistent data for all your users

brave mantle Jan 23, 2019, 9:53 AM

#

now I have everything containerised, I'd rather use mongodb, but I can't move it now :P

junior cloak Jan 23, 2019, 9:56 AM

#

and i would buy you a solid gold jet ski right now if you could make mongodb cache transient data on a very high-volume web app at even 15% of the performance youd get from redis

#

but i recognize this is not a concern for most projects at this moment

#

and i apologize for annoying anyone

brave mantle Jan 23, 2019, 9:57 AM

#

that's not what redis is being used for

#

:P

#

which is the problem

#

the entire forum's storage is on redis

junior cloak Jan 23, 2019, 9:57 AM

#

what are you using it for

#

holy shit

#

wait a sec... i remember years back some comment or forum startup writing about that

brave mantle Jan 23, 2019, 9:57 AM

#

luckily I do have the RAM to spare

junior cloak Jan 23, 2019, 9:57 AM

#

moot or something

#

i mean, being in RAM is very good, you just want it to also be somewhere else too

brave mantle Jan 23, 2019, 9:58 AM

#

yeah, and it does flush fine, but it's not ideal

#

redis' insecure-by-default configuration caused a few problems as well when the hypervisor's firewall decided to not work properly

#

no more proxmox for me

junior cloak Jan 23, 2019, 9:59 AM

#

i believe that changed in some releases in package managers at some point

so yeah that was fun

#

do not use proxmox

#

:v

junior cloak Jan 23, 2019, 10:00 AM

#

oh so it was proxmox not just the redis port being open

brave mantle Jan 23, 2019, 10:00 AM

#

proxmox provides a firewall config

#

and yeah it wasn't applying it at all

junior cloak Jan 23, 2019, 10:00 AM

#

i have never used proxmox but have largely avoided it intentionally

brave mantle Jan 23, 2019, 10:00 AM

#

but it would have been nice to have the extra layer

#

yeah I use salt and docker now

junior cloak Jan 23, 2019, 10:01 AM

#

people were pushing it at me for a couple years

#

not for dev virtualization but when i was building the crazy storage shit we were using

#

(like 600tb+ of data on-premises that also had to be accessble over 10GbE to anyone who might need it at the time)

#

zfs and whatnot

brave mantle Jan 23, 2019, 10:02 AM

#

I maintain a metric fuckton of containers

#

there's something like 100 containers on this thing

junior cloak Jan 23, 2019, 10:02 AM

#

no idea really how proxmox would help but i guess people also use it for zfs and/or ceph storage and such

brave mantle Jan 23, 2019, 10:02 AM

#

but it's all hobbyist stuff really

#

hosting for other orgs

#

that sort of thing

#

yes, proxmox has zfs

junior cloak Jan 23, 2019, 10:03 AM

#

well then that explains why it came up a lot

#

but those servers had to do very little other than be very very fast storage

brave mantle Jan 23, 2019, 10:03 AM

#

I mean, just like everything else that uses zfs, the support is experimental

#

but it does have it

junior cloak Jan 23, 2019, 10:04 AM

#

and as youe witnessed already i tend to favor what at least i belive to be a minimalist approach unless otherwise needed

#

so i never bothered with it or anything else, if i ran tons of containers i might

#

though in my brief period of that iw as using smartos

brave mantle Jan 23, 2019, 10:04 AM

#

don't bother with it for containers either

junior cloak Jan 23, 2019, 10:04 AM

#

if that even exists

brave mantle Jan 23, 2019, 10:04 AM

#

it doesn't even do docker

#

just LXC containers straight up

junior cloak Jan 23, 2019, 10:05 AM

#

i dont bother with almost anything for containers

brave mantle Jan 23, 2019, 10:05 AM

#

docker has a ton of value these days

#

I tend to recommend it for everyone

junior cloak Jan 23, 2019, 10:05 AM

#

oh yeah i mean

#

i have 7 or 8 running right now

#

but im not doing hundrds at once

#

and i only use them to dev locally

#

very occasoinally something used elsewhere on the same network but internally and low volume

#

nothing that requires more than a shitty computer and a regular server install of your favorite distro and docker

brave mantle Jan 23, 2019, 10:07 AM

#

actually this is way less than I thought, I forgot I offloaded a bunch of stuff

📎 unknown.png

junior cloak Jan 23, 2019, 10:07 AM

#

is that ajenti or someting

brave mantle Jan 23, 2019, 10:07 AM

#

it's datadog

junior cloak Jan 23, 2019, 10:07 AM

#

also, yes good lord that is a lot of containers

brave mantle Jan 23, 2019, 10:08 AM

#

I also committed the other sin of hosting

#

this is running on arch linux

junior cloak Jan 23, 2019, 10:08 AM

#

haha

#

oh yes, arch linux

brave mantle Jan 23, 2019, 10:08 AM

#

but considering the entire thing only relies on like 3 packages

#

that's fine by me

junior cloak Jan 23, 2019, 10:08 AM

#

arch linux is in the realm of like vim

#

in terms of, yes it proably works the best for you

#

but the 1% of whom that applies to are the only ones who are able to make it work at all

#

90% who try to install it at the recommendation of Smart Linux Power User From IRC probably meanwhile dont even think about lnux for 6 months because of the trauma of the experience

brave mantle Jan 23, 2019, 10:10 AM

#

haha, I've heard that

#

it's absolutely true of IRC

#

I've walked a bunch of people through it on this guild though and they're mostly happy with it

#

a few people I've recommended to use antergos or manjaro instead though

#

(they're arch-based but more user friendly)

junior cloak Jan 23, 2019, 10:12 AM

#

i use what i use but i try to make sure to recommend things that seem like they might make sense for the audience

#

perhaps not always successfully, but i at least know better htan to recommend the hardest thing to someone asking for a recommendation i.e. they know nothing about it, or they would not ask

brave mantle Jan 23, 2019, 10:13 AM

#

the thing with arch

#

is that it actually is a lot more user friendly, ONCE SET UP, than distros like ubuntu

#

it's getting to that point that's the problem

junior cloak Jan 23, 2019, 10:13 AM

#

my flying car will be amazing once it flies instead of drives

brave mantle Jan 23, 2019, 10:13 AM

#

because if you keep your shit up to date, it Just Works

#

yeah pretty much lol

junior cloak Jan 23, 2019, 10:14 AM

#

this is mostly hyperbole

#

i have no issue with arch and havent tried it in years

#

but some of the esoteric arguments bother me when someone asking is clearly the type of person who is going to need something that works out of the box

brave mantle Jan 23, 2019, 10:14 AM

#

yeah

#

in which case, antergos or manjaro

junior cloak Jan 23, 2019, 10:15 AM

#

i'll look at those

#

heard of manjaro, not used, not sure ive heard of the other

#

i think we talked the other day when i mentioned i'm on fedora 29 now, and that it's been a very long ride but 29 finally works perfectly out of the box while retaining all the things i prefer about it to ubuntu

#

i wasnt alone in that assessment of 29 apparently

#

but yeah the more, the merrier

#

they should all work like that eventually

brave mantle Jan 23, 2019, 10:18 AM

#

this is starting to get a bit off-topic but I think arch's big strengths come in because of its package management

#

you're not dealing with yum, which is often ancient and breaks on python updates

#

you're not dealing with apt, which has a big tendency to get stuck in dependency hell and has an RCE

#

there is only ever one version available of any package (unless you have an older one cached) and all the versions always line up

junior cloak Jan 23, 2019, 10:21 AM

#

dnf fixed most of the yum issues, and the bigger (and definitely not ready yet but impending) thing is the ostree stuff that is a gamechanger

brave mantle Jan 23, 2019, 10:22 AM

#

yeah, they really would have had to fix yum

junior cloak Jan 23, 2019, 10:22 AM

#

just making all packages including system updates immutable and controlled

brave mantle Jan 23, 2019, 10:22 AM

#

it was pretty garbage for a while

@prime ridge i'm about to sleep but meant to respond to this. as luck would have it, i spent about 6 months working alongside a Go wizard while we built microservices for a very high-traffic web service, constantly comparing against each other for various use cases and also trying to one-up each other. my tdlr would be... yeah, of course Go is going to perform better in most areas, as a compiled statically typed language, but there are some areas where python can come close or outperform it, which in my experience is things like performance and concurrency for high-volume web apps when it's mostly network io, little cpu work, and also if you are doing all of these things with asyncio. so, writing a websocket server or something that has 45k connected users at once is the sort of thing you can make python match or exceed at.

#

Python will not be comparable in performance for heavy computation, cpu-bound work, etc. You will never write a video encoder in native python that would be faster than in Go, or a JSON parser, or a 3D video game. But some of the web stuff, python can hold its weight for sure. whether python is preferable for you depends on how well you know either language and whether or not your use case actually needs the benefits you'd get from one or the other. I'd say that python made way more sense to me, the friend/coworker who was writing Go would say Go clearly made more sense, I'd say my code was easily readible and could be written faster, he'd tell me that his was type-safe and would run safer... in the end we were both happy and all of our services were extremely fast. the choice is yours 😃

junior cloak Jan 23, 2019, 9:09 PM

@prime ridge haha so you prefer Go but were just asking here? What’s your company build? To be clear, for most web stuff apps in python the way most people build them, Go will run circles around it. Like you’re never going to make a flask api come close to go http with goroutines

#

But if you are in the camp that went all-in on asyncio as opposed to who hate it, and familiar with asgi or building on top of uvloop and whatnot, then you can

#

And it’s all preference. I prefer python personally and know it better so it was in my own interest to try to push it as far as it could when the Go battle was happening, and I pretty much only write async code these days

#

If I knew Go better and the existing stack was synchronous wsgi then I’d be pushing for Go

#

(Assuming of course we needed the speed benefits and the whole team could make it happen. The biggest no- no is rewriting something for no particular reason)

Hi friends, I'm looking for some suggestions on my release process. My Django app ships with some fundamental db data that I load in a migration. Every 1-2 months, an additional entry in that data needs to be added, so I would add that in a release. I'm guessing I would ship that new entry as its own migration, right? It just seems sad to have a whole migration to add one entry.

#

Perhaps it would be better to update/insert them every time the app starts, avoiding the migration clunkiness. At most, it's going to grow to maybe 120 entries so that's not too bad to repeat every time the app starts, right?

I think creating data migration is better, because whenever you change your model, you have to change your fixture also. After some time, it would be overwhelming.

#

But it is still an option though

last forge Jan 23, 2019, 10:13 PM

#

I don’t anticipate the model changing (famous last words)

Data migrations are the way to go 👍🏻

any1 have some free sources for someone who is a beginnger in python and wanting to learn Django?

prime ridge Jan 24, 2019, 1:29 AM

#

Current stack is synchronous wsgi. We use Django and Python (sometimes flask). If we need async programming we have to setup celery workers to consume tasks, etc

#

@junior cloak

#

The entire process feels overly complex and makes deployment of small apps that need basic asynchronous actions like sending an email or pulling data from an API in the background a big chore.

hey all... making browser sources for twitch with my django site with some JS. quick question, is there a way to monitor for hits to a certain database? and display that content on a page as soon as an entry is created?

primal sinew Jan 24, 2019, 10:54 AM

#

Hi people. Hope you're all well? Do you mind if I ask a question with regards to Flask-WTF?

native tide Jan 24, 2019, 11:03 AM

#

psst, just ask 😉

primal sinew Jan 24, 2019, 11:11 AM

#

OK sorry. Lol.

#

Apologies for my ignorance on the subject. I am just getting my feet wet with Web Dev with Python and Flask. I am trying to create an app that will take a string from an input field and convert it into a hash and display it on an output page. However, I am not sure if my form is set up correctly. When I run the application it only returns a false value and displays that the user has not inputted anything even when I type in a random string. What I would like is to have the app return back an error if nothing is entered but run the application correctly if something is entered.

#

from flask import Flask, render_template, request, url_for, flash, redirect
from message import MessageForm, validators, ValidationError
from cryptography.fernet import Fernet

app = Flask(name)
app.secret_key = 'development'

key = Fernet.generate_key()
f = Fernet(key)

@app.route('/', methods=['GET', 'POST'])
def home():
form = MessageForm(request.form)

if request.method == 'POST' and form.validate_on_submit():
user_message = form.message_field.data
e = user_message.encode(encoding='UTF-8')
token = f.encrypt(e)
output = bytes.decode(token)
return redirect('output.html', output=output)

return render_template('index.html', form=form)

if name == ('main'):
app.run(debug=True)

#

That's the code.

#

{% extends 'layout.html' %}

{% block body %}

<br />
<form action="/" method="POST">
<div class="form-group">
<label style="font-weight: bold;">{{ form.message_field.label }}</label>
<input type="text" class="form-control" name="message" id="message">
<br />
<button type="submit" class="btn btn-primary btn-lg btn-block">Encrypt Message</button>
</div>
</form>

{% for message in form.message_field.errors %}
<div class="alert alert-danger" role="alert">
{{ message }}
</div>
{% endfor %}

{% endblock %}

#

Here is the HTML template.

#

Any help would be greatly appreciated. Thank you.

junior cloak Jan 24, 2019, 12:31 PM

@prime ridge how do you do background tasks now? I can’t imagine you just block and make the client wait while you do those. You definitely don’t need to use something celery (gross) to run synchronous code without blocking. run_in_executor is the quick and dirty way to do a lot of it. It’s small apps doing network io that benefit the most from async.

#

But like I mentioned, if you don’t actually need it, then you’re right, don’t bother. But some apps do, the example I mentioned when building stuff alongside Go, for instance—that was a web app getting hundreds to thousands of requests a second, and scaling in a way we could manage without going broke was paramount. In that situation, moving the api away from flask to aiohttp+uvloop resulted in, depending on the task, between 5x and 11x performance boost in terms of how many concurrent requests could be handled with the exact same resources, which is... insane, and for some projects necessary to survive. Most don’t — but keep it mind for if you do grow to that point 😃 python gets a bad reputation as being slow with stuff like this but it does not have to be the case

prime ridge Jan 24, 2019, 4:13 PM

#

I was saying celery for those. E.g. for api calls or emails. It's definitely not built for scaling -- you run just how many celery workers you need usually

Anyone able to assist with running a code block when a submit button is clicked using Flask-WTF? I have a submit button that when clicked I would like it to copy a string to the clipboard.

brave mantle Jan 25, 2019, 1:23 PM

#

You won't be doing that with Python

#

You'll need JavaScript (and maybe Flash)

primal sinew Jan 25, 2019, 1:26 PM

#

@brave mantle OK thanks. Will do some digging.

primal sinew Jan 25, 2019, 2:21 PM

#

Is there no way to do this with another route?

brave mantle Jan 25, 2019, 2:21 PM

#

Nope, the Python doesn't run in the browser

#

And most browsers don't want to give direct access to the clipboard either

primal sinew Jan 25, 2019, 2:22 PM

Might output to a file in that case. I'll look into it thanks.
