You set up a rest api, setup the endpoints you need, setup auth

#

depends on what you specifically mean

care to elaborate.?

hello, im following this DO tutorial

#

https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-18-04

DigitalOcean

How To Install Nginx on Ubuntu 18.04 | DigitalOcean

Nginx is one of the most popular web servers in the world and is responsible for hosting some of the largest and highest-traffic sites on the internet. It is more resource-friendly than Apache in most cases and can be used as a web server or reverse p

#

and I'm a bit confused in the server block portion

#

specifically this section ```server {
listen 80;
listen [::]:80;

    root /var/www/example.com/html;
    index index.html index.htm index.nginx-debian.html;

    server_name example.com www.example.com;

    location / {
            try_files $uri $uri/ =404;
    }

}```

#

so for this line server_name example.com www.example.com;

#

the actual website im trying to host on there has its DNS (?) set up as such

#

example.example.com

#

does that make a difference?

#

should I do server_name example.com example.example.com

Hello

crystal quartz Jul 21, 2020, 3:11 PM

#

Hello everyone, I have a flask app which is set up to send emails to users. I would like to format these using html which I know how to do technically but I absolutely hate trying to build the HTML content in python because message_content="<html><h1>" + str(a) + etc etc is a total pain. Is there some sort of way I can use jinja or another technology/extension to make this easier?

flint breach Jul 21, 2020, 3:12 PM

#

perhaps, jinja2 or some templating engine would do you good

quick cargo Jul 21, 2020, 3:13 PM

#

Flask has a jinja engine built into it

crystal quartz Jul 21, 2020, 3:13 PM

#

Yeah, 100% - I use jinja2 to serve the html for my web pages, and I love it - but how do I repurpose this to get the jinja2 output to a string rather than display to the user?

quick cargo Jul 21, 2020, 3:13 PM

#

jinja outputs a string by default

#

its just flask's render_template that formats the template and returns it with the content types etc...

crystal quartz Jul 21, 2020, 3:14 PM

#

ok, great - and I'm sorry to be really dumb about this, but...

#

at the moment I use a command like:

#

return render_template('users/list.html', user_list=user_list)

#

which does the jinja magic itself

quick cargo Jul 21, 2020, 3:16 PM

#

from jinja2 import Environment, FileSystemLoader

template_env = Environment(loader=FileSystemLoader(searchpath="./templates"), auto_reload=True)
def render_template(name, **context):
    template = template_env.get_template(name)
    return template.render(**context)```

is a quick and dirty way

crystal quartz Jul 21, 2020, 3:17 PM

#

awesome, thank you

#

that's really helpful

sick pulsar Jul 21, 2020, 3:33 PM

#

for anyone that does flask, what's the 'typical' way to implement text searching

broken basin Jul 21, 2020, 3:38 PM

#

Hello Developrs

#

I have to verify Heroku account to add custom domain but none of my card is not working with heroku.
Any alternative ?

cold anchor Jul 21, 2020, 4:04 PM

#

@crystal quartz you can just use flask's render template, no need to reinvent it

#

here's an example I have of sending an account verify email:


class UserController:
    ...

    @staticmethod
    def verify_user(user):
        """Send the verification email the user."""
        if current_app.config.get('SEND_EMAILS'):
            ses_client = boto3.client('ses')
            ses_client.send_email(
                Source=current_app.config['FROM_EMAIL'],
                Destination={
                    'ToAddresses': [user.email],
                },
                Message={
                    'Subject': {
                        'Data': 'Verify your email address'
                    },
                    'Body': {
                        'Html': {
                            'Data': render_template(
                                'emails/verify.html',
                                verification_link='{}'.format(UserController.make_verify_link(user))
                            )
                        }
                    }
                }
            )
        else:
            current_app.logger.info('skipping email send')

Guys, I am developing an app in flask and for whatever reason I need an object which I create in the create_app to be accessible everywhere.

#

I could assign it into app.something = ... but that seems wrong to me.

cold anchor Jul 21, 2020, 4:06 PM

#

what are you using the object for?

modern hearth Jul 21, 2020, 4:06 PM

#

Well, a json store

#

dont ask me why

#

lol

cold anchor Jul 21, 2020, 4:06 PM

#

there's nothing wrong with assigning it to the app object as long as it doesn't change over time

modern hearth Jul 21, 2020, 4:06 PM

#

yeah but intellisense wont discover it

#

which will drive me crazy 😄

#

so I would need to inherit from the Flask object in order for it to work with intellisense

#

but that seems like an overkill to me

#

I also tried making the object static (without instantiating)

#

but I actually need to access the app.instance_path

#

so I need to refer to the app

#

but it gave me an error about the context

#

any ideas?

cold anchor Jul 21, 2020, 4:12 PM

#

I would just add it to the object, though I personally don't care about my editor giving me code completion

modern hearth Jul 21, 2020, 4:17 PM

#

well okay then

#

thanks

halcyon swan Jul 21, 2020, 4:21 PM

I can't seem to find an a good guide on parsing jsons and getting certain values I mostly use javascript.

#

{
  "connections": [
    {
      "friend_sync": false, 
      "id": "", 
      "name": "Otis_Goodman", 
      "show_activity": true, 
      "type": "reddit", 
      "verified": true, 
      "visibility": 1
    }, 
    {
      "friend_sync": false, 
      "id": "", 
      "name": "Otis_Goodman", 
      "show_activity": true, 
      "type": "steam", 
      "verified": true, 
      "visibility": 1
    }, 
    {
      "friend_sync": false, 
      "id": "", 
      "name": "OtisGoodman", 
      "show_activity": false, 
      "type": "xbox", 
      "verified": true, 
      "visibility": 1
    }
  ], 
  "user": {
    "avatar": "", 
    "discriminator": "", 
    "flags": 256, 
    "id": "", 
    "locale": "en-US", 
    "mfa_enabled": true, 
    "public_flags": 256, 
    "username": "Otis Goodman"
  }
}

#

test the type xboxto see if it exists in a json

#

I would also like to try to get the id type from user but I am not sure how to get it without confusing with the other id types

flint breach Jul 21, 2020, 4:29 PM

#

basically you parse the json, which is basically a dictionary in python once deserialized then you simply iterate through the connection keys to get individual objects

for obj in dictionary['connections']:
  print(obj)

#

look into the json module

#

specifially json.dump and json.load if it's a file, or json.dumps and json.loads if you're making requests (in memory json)

#

if you're using javascript, the same principle applies, you just don't need any specific "javascript modules"

#

if you've got any questions, feel free to ping me

Anyone here a flask expert? very good with blueprints/namespaces?

I've used flask before, but nothing really advanced and I now I have to debug a flask issue, but I can't figure out what the problem is.

I was able to read the docs and create my own flask app using blueprints and namespaces but I still can't debug the original.

I just get a 404 with no other errors. Can anyone help?

what are pros and cons of flask and django?

flint breach Jul 21, 2020, 5:15 PM

#

it's heavy weight and opinionated, but that's a pro and con

#

it's batteries included, meaning it's got a lot of stuff built in, which you'll probably need anyway

#

lots of third party apps for anything you'll need

#

lots of magic underneath though, things that are implicit that you can gain knowledge of with time

#

overall it's preety sweet, i can recommend some playing around with it

coral wind Jul 21, 2020, 5:16 PM

#

youare talking about flask?

flint breach Jul 21, 2020, 5:18 PM

is this what u mean?

flint breach Jul 21, 2020, 5:52 PM

did you try what i wrote earlier?

#

it's basically a dictionary in python

#

for obj in dictionary['connections']:
  print(obj)```

flint breach Jul 21, 2020, 5:58 PM

the dictionary is just a variable

#

cna you show the code where you get the json object

#

not the json itself

Hey I have a few questions about implementing zoom oauth in django, I've taken a look at allauth and it doesn't support zoom. I've also seen django oauth toolkit, bit I'm not too sure about the implementation. Lastly I saw DRF's django-rest-framework-social-oauth2, looks like this might help, but I'm not sure.

#

@flint breach how would I query if xbox type exists?

flint breach Jul 21, 2020, 7:18 PM

#

what is the difference between django-admin startproject projectname and django-admin startproject projectname.
@native tide nothing, if you mean django-admin startproject projectname ., then it basically treates the current directory as the project root

#

otherwise it creates a new directory named projectname and treats that as the project root

#

@flint breach how would I query if xbox type exists?
@halcyon swan xbox type?

#

aha

#

basically iterate through each object

#

and again, the obj is a dictionary

#

obj['type'] == 'xbox' should be enough

native tide Jul 21, 2020, 7:22 PM

#

ok

flint breach Jul 21, 2020, 7:23 PM

#

basically it's just a convinience

#

also, like most shell commands

#

django-admin startproject --help
usage: django-admin startproject [-h] [--template TEMPLATE] [--extension EXTENSIONS]
                                 [--name FILES] [--version] [-v {0,1,2,3}]
                                 [--settings SETTINGS] [--pythonpath PYTHONPATH]
                                 [--traceback] [--no-color] [--force-color]
                                 name [directory]

#

using --help as a positonal argument will usually reveal the possible options

#

the things in square brackets are optional

Hey!
That's just a basic User-Profile Signal file, but my question is, why do I have to include save_profile as well? If I update user, then I update profile as well at the same time, and I also save it. So that's just doesn't make sense.

def create_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)


@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
    instance.profile.save()```
What do you say?

Hello web-dev heroes, I am using Flask and I'm a bit confused about how to pass variables. I have a route which is designed to accept form input, which it does fine, but I would also like the option to manually call this definition in my code in other scenarios (DRY) but I'm unsure how to set it up to accept both form input and input from another python call

#

Code as it stands:

#

def mydefname(user_id):
    comment = request.form.get('comment')```

#

I can happily pass the "user_id" element from another definition

#

but how do I also pass the "comment" variable from python while maintaining the ability to also have it populated by the form

Hi I have a Django Rest Framework question:
what's the difference between APIView and ViewSet?
I'm making a big app(online register), that after a call to an endpoint will have to do many things
(example: Add student/Teacher/admin to class and return class connection code)

Currently I've made everything work with APIViews(And it works great!), But every time I look in documentation I can see that I might
have better routing and better browsable web api. And that overall it could be easier especially if I would want to use action decorator to perform different operations on the same View

So my question is can I just change my APIViews to ViewSets, and is it a good idea?

mellow gyro Jul 23, 2020, 1:20 PM

@stable egret I'm not a freelancer but i have many friends who are. They just learn a backend language they are comfortable with and make projects on their own, to learn. (this language is 90% nodejs or in that area( see expressJS, typescript, nextjs,..))
then they start looking at a frontend framework that interests them the most, again by practicing a lot. Most of them pick one of the big three ( Angular, React or Vue )
and the main thing i saw them do was practice, make some for friends/family without any pay, just to learn the languages and learn to work with customers.
And once you feel ready to get your name out there, just go for it, don't be afraid. you learn a lot along the way as well !

If you want to learn Python, go for it!
I'd rather go with JS and then NodeJS if you really want to freelance in web development but that is personal
Python is also an option with Django.
it's just that with JS you have more roads to walk on, you can go vanilla js, take on a framework likes express or next or nuxt or redux or ...
and for the front end you have even more haha see Angular/AngularJS, React, Ember, Vue, jQuery, backbone,....

that Flask Mail package hasn't been updated in like 10 years, probably very insecure at this point

if you want to send emails from python it's a lot easier to use something like Sendgrid or AWS SES

@cold anchor you mean mail.connect()?

cold anchor Jul 23, 2020, 2:42 PM

Does anyone have a good, concise video or tutorial on the basics of HTML/CSS

#

I'm interested in learning basic stuff, and maybe making my own website. I still dont quite understand the difference between Django, JS, Flask, NodeJS, etc.

#

Like is front end completely HTML, CSS, and JS?

#

Then backend stuff (which i dont evne know what that means) is Django?

brave karma Jul 23, 2020, 3:26 PM

#

how would i use django for a database where there are embedded documents more than 2 levels deep

#

im currently trying out djongo cuz the other nosql, nonrel option projects are not maintained

#

django-nonrel hasnt been maintained for 8 years

#

only option seems to be djongo but i cant embed models more than once

glass sandal Jul 23, 2020, 3:30 PM

#

Yep

#

Add !important

#

Befor the semi-colon

#

So like :

body {
    background-image: linear-gradient((#fdfcfb),(#e2d1c3)) !important;
}

#

@native tide

#

Remove the (

#

Just do like :

body {
    background-image: linear-gradient(#fdfcfb,#e2d1c3) !important;
}

#

Oh and nothing will happen by doing like :

body {
    background-image: linear-gradient(to right,#fdfcfb,#e2d1c3) !important;
}

#

Or maybe first try like a color by word

#

like red and blue

#

Try that to make sure it's not your browser probkem

#

problem*

#

Good

#

np

#

It overrides the value

#

e.g

#

When you have this :

a {
  color: #444;
  color: black !important;
}

The color would be black , not #444

#

And idk why , but gradients don't seem to work for me either (without !important)

#

So that's my prob too

#

yeah lol

#

?

#

Oh

#

Just do :

body {
  margin: 0px;
}

and set your item width/height to 100%

#

It's work

#

Or if your items are in a div or something , in addition to this , do :

#div_id {
  margin: 0px;
}

too

#

Don't forget to set the width of div to 100% too!

#

:)

#

Well , now you know

@brave karma if you want nosql for your site, honestly, just use a different framework than Django.

#

flask is pretty good. or if you want more speed, try an async one and some sort of async ORM?

brave karma Jul 23, 2020, 4:11 PM

#

dang just learned django for the code jam and wanted to use it :/

deep cave Jul 23, 2020, 4:12 PM

#

then don't use nosql

#

what's wrong with postgres?

#

Django isn't designed for blazing speed but it's still fast enough for most things.

quick cargo Jul 23, 2020, 4:16 PM

#

Django does have support for mongodb tbh

#

but i would go with a SQL option for Django overall

#

or any framework thats async for that matter aswell due to nosql options being rather lacking

slender whale Jul 23, 2020, 4:23 PM

I'm trying to control the placement of a table within a webpage using a jinja2 template

template_str = """<!DOCTYPE html>
<html>
<head>
</head>
<body>
    <div style = "poisition:; left:200px; top:400px;">
        {{table}}
    </div>
</body>
</html>
"""

#

However that is not controlling the placement at all. Is there soemthing I am doing wrong?

#

The table HTML would ideally be coming from pandas.DataFrame.style.render() (this outputs a table html/css string)

brave karma Jul 23, 2020, 4:26 PM

#

theres nothing wrong with postgres its just that the discord bot was made first and made with mongodb

#

not really sure if i wanna rewrite all of that

#

i dont think its worth it, even tho django is great

#

i think im gonna use sanic since the discord bot is using an async client for mongodb but im gonna miss some of django's built in stuff

#

until the code jam 🙂

quick cargo Jul 23, 2020, 4:29 PM

#

i hate mongo motor enough to just have a thread pool and just executor pymongo tbh

slender whale Jul 23, 2020, 4:55 PM

#

Can you control the overall position of a table element by stuffing it inside of a div?

cold anchor Jul 23, 2020, 4:56 PM

#

you're giving CSS positions without changing the position attribute to something that makes sense for it like relative, absolute or sticky

#

based on what you have, try doing position: absolute;

slender whale Jul 23, 2020, 4:59 PM

#

position: absolute and position: relative do nothing at all it seems. I was originally using relative I apologize I must have copied it during a different attempt

#

Are you sure you have an index.html file in your templates folder?

azure saddle Jul 23, 2020, 5:41 PM

yeh I have

#

but I made an template folder in some other dir

glass sandal Jul 23, 2020, 5:41 PM

Then you have to point to that dir

azure saddle Jul 23, 2020, 5:42 PM

#

is there any specific templates folder that is there where we create the html file?

#

yeh I gave an direct path to it

glass sandal Jul 23, 2020, 5:42 PM

#

So when you wanted to define your app/blueprint you told the app the template folder path right?

azure saddle Jul 23, 2020, 5:44 PM

like I have a folder A there is a main.py file where I'm trying to render the template
and in that same folder A there is another folder named template where I have kept my index.html file

So could you just send a directory tree?

@glass sandal yeh I tried many a times tho

#

@glass sandal ok

Like :
a

?

#

yeh

same

azure saddle Jul 23, 2020, 5:45 PM

#

yes

glass sandal Jul 23, 2020, 5:46 PM

#

And your app/blueprint must be defined like :

app = Flask(__name__,template_folder="template")

#

Right?

#

Either rename the folder to "templates" or do that

native tide Jul 23, 2020, 5:47 PM

#

in case it's named template

glass sandal Jul 23, 2020, 5:47 PM

Oh so then he/she has to define the folder in app definition

azure saddle Jul 23, 2020, 5:48 PM

#

And your app/blueprint must be defined like :
app = Flask(__name__,template_folder="template")

@glass sandal well it is like

def home():
    # if NAME_KEY not in session:
    #   return redirect(url_for("login"))

    # name = session[NAME_KEY]
    return render_template('website\\application\\templates\\index.html')

azure saddle Jul 23, 2020, 5:48 PM

??

native tide Jul 23, 2020, 5:48 PM

just render 'index.html'

azure saddle Jul 23, 2020, 5:48 PM

#

this one?

glass sandal Jul 23, 2020, 5:48 PM

#

You must not give direct paths

native tide Jul 23, 2020, 5:48 PM

#

it will look into template for index.html

glass sandal Jul 23, 2020, 5:48 PM

#

To the template folder

#

Just do "index.html"

#

return render_template("index.html")

azure saddle Jul 23, 2020, 5:49 PM

#

yeh I tried that

just render 'index.html'
@native tide

def home():
    # if NAME_KEY not in session:
    #   return redirect(url_for("login"))

    # name = session[NAME_KEY]
    return render_template('index.html')

glass sandal Jul 23, 2020, 5:49 PM

#

Yes .

#

And then define your template folder in app definition

azure saddle Jul 23, 2020, 5:49 PM

#

but still it was the same error

native tide Jul 23, 2020, 5:49 PM

#

is your templates folder named templates or template?

glass sandal Jul 23, 2020, 5:49 PM

#

Or blueprint defenition

azure saddle Jul 23, 2020, 5:49 PM

#

wait let me share a ss

native tide Jul 23, 2020, 5:49 PM

#

please

azure saddle Jul 23, 2020, 5:49 PM

#

just a min

glass sandal Jul 23, 2020, 5:50 PM

#

Just ... You know, you use blueprints or you have a single app?

azure saddle Jul 23, 2020, 5:50 PM

#

templates

glass sandal Jul 23, 2020, 5:50 PM

#

You use blueprints or a single app variable?

azure saddle Jul 23, 2020, 5:50 PM

#

Just ... You know, you use blueprints or you have a single app?
@glass sandal well I'm really new in web-dev tho so I don't know this

glass sandal Jul 23, 2020, 5:50 PM

#

Oh so you use app

#

So define your app like :

app = Flask(__name__,template_folder="website/application/templates")

#

And then you can just say "index.html"

azure saddle Jul 23, 2020, 5:52 PM

#

well It is not like that the dir tree is like
A
-main.py
-application
--templates
---index.html

#

well wait let me share my code

glass sandal Jul 23, 2020, 5:53 PM

#

So do "templates" instead of that

#

or "application/templates"

native tide Jul 23, 2020, 5:53 PM

#

You dont have to use templates, that's the default, if it's on the same level as the app

glass sandal Jul 23, 2020, 5:53 PM

#

@native tide His/Her main.py file is one dir upper

#

So she/he needs too

azure saddle Jul 23, 2020, 5:53 PM

#

from flask import Flask, render_template, url_for, redirect, request, session

app = Flask(__name__)
app.secret_key = "hello"

@app.route("/login")

@app.route("/logout")

    return redirect(url_for("login"))


@app.route("/")
@app.route("/home")

    return render_template('website\\application\\templates\\index.html')


if __name__ == "__main__":
    app.run(debug=True)

glass sandal Jul 23, 2020, 5:54 PM

#

So you see app = Flask(name_)?

native tide Jul 23, 2020, 5:54 PM

#

Yeah okay, if it is as you pointed @azure saddle , add what RaderH2O suggested, applciation/templates

glass sandal Jul 23, 2020, 5:54 PM

#

Change it too

azure saddle Jul 23, 2020, 5:54 PM

#

then I may remove templates file?

#

yes

glass sandal Jul 23, 2020, 5:54 PM

#

app = Flask(__name__,template_folder="application/templates")

azure saddle Jul 23, 2020, 5:55 PM

#

ohkk

glass sandal Jul 23, 2020, 5:55 PM

#

Change it to that ^

#

And

#

Your render template

native tide Jul 23, 2020, 5:55 PM

#

and ```py
return render_template('website\application\templates\index.html')

glass sandal Jul 23, 2020, 5:55 PM

#

Needs to be changed to return render_template("index.html")

native tide Jul 23, 2020, 5:55 PM

#

to py render_template('index.html')

glass sandal Jul 23, 2020, 5:55 PM

#

Yes

azure saddle Jul 23, 2020, 5:55 PM

#

ohkkk thanks ppl very mcuh😊

azure saddle Jul 23, 2020, 5:56 PM

#

yeh I hope😊

#

ohhhh yesssssssssssssssss

glass sandal Jul 23, 2020, 5:57 PM

#

It worked?

azure saddle Jul 23, 2020, 5:57 PM

#

thank you @glass sandal and @native tide very much it works really fine

glass sandal Jul 23, 2020, 5:58 PM

Nah np

azure saddle Jul 23, 2020, 5:58 PM

#

yeh😊🙏

glass sandal Jul 23, 2020, 5:58 PM

#

Nice

#

You are learning from the documentation?

azure saddle Jul 23, 2020, 5:58 PM

#

yeh

#

and youtube

glass sandal Jul 23, 2020, 5:58 PM

#

Oh

#

When I was beginner , I used youtube . It's much better than the documentation .

#

Use Youtube unless you have like a network problem

#

Or you could get used to documentation

#

Which is a better choice imo

daring egret Jul 23, 2020, 5:59 PM

#

Does anyone know how to print in django some parts of a string like 0:8 or something like this?

azure saddle Jul 23, 2020, 5:59 PM

#

well I was making a chat room using sockets and making a server
then I saw using Flask for GUI than CLI is better so I made a server and then I'm making a whole website lol

glass sandal Jul 23, 2020, 6:00 PM

#

Oh I see lol

azure saddle Jul 23, 2020, 6:00 PM

#

When I was beginner , I used youtube . It's much better than the documentation .
@glass sandal yeh youtube is good

glass sandal Jul 23, 2020, 6:00 PM

#

Yeah

#

@daring egret wdym?

#

Oh

#

You mean like string[0:8]?

daring egret Jul 23, 2020, 6:00 PM

#

yeah

glass sandal Jul 23, 2020, 6:01 PM

#

Oh so imo it's good to refrence it in views.py

native tide Jul 23, 2020, 6:01 PM

#

@daring egret https://docs.djangoproject.com/en/3.1/ref/templates/builtins/#slice

Built-in template tags and filters | Django documentation | Django

glass sandal Jul 23, 2020, 6:01 PM

#

And that's a better way

#

^^^^

daring egret Jul 23, 2020, 6:01 PM

#

ok

glass sandal Jul 23, 2020, 6:01 PM

#

But you can just

return render("file.html",{"string":string[0:8]})

native tide Jul 23, 2020, 6:02 PM

#

You could, yes

glass sandal Jul 23, 2020, 6:02 PM

#

Jinja has a way of doing it too right?

native tide Jul 23, 2020, 6:03 PM

#

Yup

glass sandal Jul 23, 2020, 6:03 PM

#

Oh I see

native tide Jul 23, 2020, 6:04 PM

#

return render("file.html",{"string":string[0:8]})ü

#

why

#

itss not

#

work

#

for

#

me

glass sandal Jul 23, 2020, 6:04 PM

#

Cause maybe your string is not right

native tide Jul 23, 2020, 6:04 PM

#

''''python
return render("file.html",{"string":string[0:8]})
''''

glass sandal Jul 23, 2020, 6:04 PM

#

And I wrote the line with placholders

native tide Jul 23, 2020, 6:04 PM

#

idk

#

i just know html and c++

glass sandal Jul 23, 2020, 6:05 PM

#

So file.html must be your file , and string[0:8] must be your variable

#

Like variable[0:8]

native tide Jul 23, 2020, 6:05 PM

#

ok whatever i play valorant

#

😄

glass sandal Jul 23, 2020, 6:05 PM

#

XD lol

native tide Jul 23, 2020, 6:06 PM

#

wanna play with me?

glass sandal Jul 23, 2020, 6:06 PM

#

I don't have lol

native tide Jul 23, 2020, 6:06 PM

#

So file.html must be your file , and string[0:8] must be your variable
@glass sandal Actually this works directly with jinja {{ variable[0:8] }}

#

oh

glass sandal Jul 23, 2020, 6:06 PM

#

I am on Linux

native tide Jul 23, 2020, 6:06 PM

#

ohh

glass sandal Jul 23, 2020, 6:06 PM

#

@native tide Didn't know that lol

native tide Jul 23, 2020, 6:06 PM

#

u play growtopia

#

?

glass sandal Jul 23, 2020, 6:06 PM

#

Used too*

#

Am on linux

#

I can't

#

Play

#

Windows games

#

Unless with WINE

#

That sucks for games

#

Why am I typing too instead of to lol

daring egret Jul 23, 2020, 6:12 PM

#

I found how to print that variable like in that example it's goes something like this {{variable|truncatechars: the letter at which you wish for the characters to stop}}

#

like 0 or 9

glass sandal Jul 23, 2020, 6:12 PM

#

Just do {{variable[0:9]}} as @native tide said

daring egret Jul 23, 2020, 6:12 PM

#

i tried

native tide Jul 23, 2020, 6:12 PM

#

that works with jinja2

daring egret Jul 23, 2020, 6:12 PM

#

i gave me syntax error

glass sandal Jul 23, 2020, 6:12 PM

#

You are using Django right?

#

If yes , it must work

daring egret Jul 23, 2020, 6:12 PM

#

yeah

glass sandal Jul 23, 2020, 6:13 PM

#

So what error did it give?

native tide Jul 23, 2020, 6:13 PM

#

doesnt truncate chars always follow with ...?

glass sandal Jul 23, 2020, 6:14 PM

#

I myself am not much familiar in terms of Jinja and template languages . So Idk . Maybe he could answer?

#

or she*

daring egret Jul 23, 2020, 6:14 PM

#

it add like 3 points

#

at the end to signify that the word ment to be longer

#

the {{variable[0:9]}} gives template syntax error

glass sandal Jul 23, 2020, 6:15 PM

#

Oh I see

#

Maybe the length of your string is short?

#

Oh I forgot , syntax error

native tide Jul 23, 2020, 6:15 PM

#

probably doesnt work with django's templating engine

glass sandal Jul 23, 2020, 6:15 PM

#

Yeah maybe

most people do not do backend dev when bored

#

refactor if you want to kill time 😛

glass sandal Jul 23, 2020, 6:19 PM

#

ummm...what is a refractor 😅

native tide Jul 23, 2020, 6:20 PM

#

Make your code cleaner

glass sandal Jul 23, 2020, 6:20 PM

#

Oh

#

So it prettifies code right?

native tide Jul 23, 2020, 6:20 PM

#

Thatll be your job 😛

#

but the end result should indeed be prettier code base

glass sandal Jul 23, 2020, 6:20 PM

#

Oh I see

native tide Jul 23, 2020, 6:20 PM

#

less redundancy what not

glass sandal Jul 23, 2020, 6:21 PM

#

That could be a good idea though , but ... idk .... like maybe I should just game dev

#

(Not with PyGame since it sucks imo)

daring egret Jul 23, 2020, 6:24 PM

#

go watch a tutorial for epic games unreal engine since is kinda free if i remember and make some good old tetris if killing time is on your head or do some mario idk

glass sandal Jul 23, 2020, 6:24 PM

#

Nah imma just use Love2d

#

It doesn't have shit ton of GUi which I hate as a vim user

#

And it's in Lua

#

Written in C , so it's fast

daring egret Jul 23, 2020, 6:25 PM

#

i don't belive the language matters that much

glass sandal Jul 23, 2020, 6:25 PM

#

It does

daring egret Jul 23, 2020, 6:25 PM

#

if the code is clean so is the software

glass sandal Jul 23, 2020, 6:25 PM

#

The performance

#

Is

#

Always based on language

#

C and C++ have the lead rn in term of speeds

#

speed*

#

So it'll be fast

#

And Lua itself is a light and fast aaand flexible language

daring egret Jul 23, 2020, 6:26 PM

#

yeah but it's really negligible for human eye

glass sandal Jul 23, 2020, 6:26 PM

#

Well , you can't get good performance from Python

#

Even with using Cython

#

It's still slow

#

Although being an awesome language

#

It's slow

daring egret Jul 23, 2020, 6:27 PM

#

yeah but it's flexible

dapper tusk Jul 23, 2020, 6:27 PM

#

honestly, gamedev is the only place where python cannot actually be fast

glass sandal Jul 23, 2020, 6:27 PM

#

That's why I chose love2d

daring egret Jul 23, 2020, 6:27 PM

#

the boy python stretches from gamedev to webdev

#

too bad it's not really looked for in the industry

glass sandal Jul 23, 2020, 6:28 PM

#

I mean , Game Dev when I'm bored

daring egret Jul 23, 2020, 6:28 PM

#

like java and the c boys

glass sandal Jul 23, 2020, 6:28 PM

#

Web dev when I'm working

#

C is god , but Java... WHY JAVA?

daring egret Jul 23, 2020, 6:29 PM

#

cuz everyone works with it

glass sandal Jul 23, 2020, 6:29 PM

#

Does that mean you have to use it?

daring egret Jul 23, 2020, 6:29 PM

#

you dont have to like it just do it

#

it brings home the breed

glass sandal Jul 23, 2020, 6:30 PM

#

I mean , I respect your opinion . And it's fine . But java sucks like so bad . It's the only language I actually "HATE" to use

daring egret Jul 23, 2020, 6:30 PM

#

i know

glass sandal Jul 23, 2020, 6:30 PM

#

But still , I don't wanna be biased

daring egret Jul 23, 2020, 6:30 PM

#

it's shite

glass sandal Jul 23, 2020, 6:30 PM

#

Just use what you want

dapper tusk Jul 23, 2020, 6:30 PM

#

why do people hate java so much? I never actually had much trouble with it

daring egret Jul 23, 2020, 6:30 PM

#

the syntax

glass sandal Jul 23, 2020, 6:30 PM

#

Cause it's good as a platform , sheet as a programming language

daring egret Jul 23, 2020, 6:30 PM

#

thats where it all begins

#

at the syntax

#

go to w3 school

#

watch all syntaxes

#

the look at java

glass sandal Jul 23, 2020, 6:31 PM

#

And almost eveyone that went to university , knows it

native tide Jul 23, 2020, 6:31 PM

#

The only thing I rly didnt like in Java was that you have to propagate exceptions on each method signature if you throw one

glass sandal Jul 23, 2020, 6:31 PM

#

Guys , just use Python

#

For your common things

#

AND Ai + Web dev

#

And C/C++ for life

quick cargo Jul 23, 2020, 6:32 PM

#

🤔

glass sandal Jul 23, 2020, 6:32 PM

#

Is it a problem to use C/C++?

dapper tusk Jul 23, 2020, 6:32 PM

#

you probably should not be using C for anything over 1 small file

glass sandal Jul 23, 2020, 6:33 PM

#

C/C++ is the mother of all languages and operating systems

daring egret Jul 23, 2020, 6:33 PM

#

c is used in some car sistems

glass sandal Jul 23, 2020, 6:33 PM

#

So still god

#

I mean , not ALL languages

dapper tusk Jul 23, 2020, 6:33 PM

#

C++ is not, C is also not

glass sandal Jul 23, 2020, 6:33 PM

#

But ALL official ones

dapper tusk Jul 23, 2020, 6:33 PM

#

C is pretty fundamental though

#

but you should not use it much, it is far too easy to do something incorrectly and far too hard to things correctly

glass sandal Jul 23, 2020, 6:34 PM

#

C is very fun to use . You must make the functionallity

#

Until your code gets complicated

#

Then you have to quit

native tide Jul 23, 2020, 6:34 PM

#

lol 😛

glass sandal Jul 23, 2020, 6:34 PM

#

And just

dapper tusk Jul 23, 2020, 6:34 PM

daring egret Jul 23, 2020, 6:36 PM

#

i thought only java and c-s could do the trick

dapper tusk Jul 23, 2020, 6:36 PM

#

yes, but you probably want kotlin instead

glass sandal Jul 23, 2020, 6:36 PM

#

REALLY? There is Dart + Flutter

#

Even Phonegap or Intel XDK can do the job

#

And Phonegap is basically HTML to APK if you didn't know

daring egret Jul 23, 2020, 6:37 PM

really

#

i will document myself

on this

and try it

glass sandal Jul 23, 2020, 6:37 PM

#

https://hastebin.com/fitigaruwu.js why does this give me Uncaught ReferenceError: AdminPassword is not defined?

glass sandal Jul 23, 2020, 6:56 PM

#

Maybe it's not defined?

#

Or maybe you have to use await?

native tide Jul 23, 2020, 6:57 PM

#

it was defined

dapper tusk Jul 23, 2020, 6:57 PM

#

if(promptInput == "Admin"){
    const AdminPassword = prompt("Password")
}
``` the adminpw only exists in the if

#

not outside of it

glass sandal Jul 23, 2020, 6:57 PM

#

Yeah

dapper tusk Jul 23, 2020, 6:57 PM

#

unlike in python, {} blocks get their own scope in JS

glass sandal Jul 23, 2020, 6:57 PM

#

You must define it outside it

native tide Jul 23, 2020, 6:58 PM

#

if i put it outside it triggers when i don't want it too

glass sandal Jul 23, 2020, 6:58 PM

#

Make it equal to undefined

#

const AdminPassword = undefined;

dapper tusk Jul 23, 2020, 6:59 PM

#

then it cannot be const

glass sandal Jul 23, 2020, 6:59 PM

#

Ah god js is weird

#

Make it equal to a blank string

#

""

native tide Jul 23, 2020, 6:59 PM

#

there is then no point of it

glass sandal Jul 23, 2020, 7:00 PM

#

Just define it outside so it'll be global

#

And should it be const?

#

Just make it a var

dapper tusk Jul 23, 2020, 7:00 PM

#

what you actually want is

if(promptInput === "Admin") {
    const adminPw = prompt("Password");
    if(adminPw === "TheMaster") {
        alert("welocome as admin");
    }
}

glass sandal Jul 23, 2020, 7:01 PM

#

I mean , you can define it as a var outside the if

#

Then prompt it in the if

dapper tusk Jul 23, 2020, 7:01 PM

#

better to not have variables

glass sandal Jul 23, 2020, 7:01 PM

#

And check for it

#

You can delete them I doubt

#

?

#

Or make them like undefined

native tide Jul 23, 2020, 7:02 PM

#

ok thanks

dapper tusk Jul 23, 2020, 7:02 PM

#

yes, but this way you never have adminPw hold a value that is not an admin password

glass sandal Jul 23, 2020, 7:02 PM

#

wdym?

#

Why shouldn't it hold a value that's not an admin pw?

dapper tusk Jul 23, 2020, 7:03 PM

#

because the variable is called AdminPassword. How does it make sense for it to not hold the admin password?

glass sandal Jul 23, 2020, 7:03 PM

#

I mean , he/she wants not to have vars

#

Oh

#

Maybe like there is a global way to do it?

#

Like defining a global const var inside brackets

#

Isn't it a way to do that in js?

#

He could make a trigger

#

Like isDefined

If it's true , define a const adminpw variable

#

And hold the prompt as a variable

#

That you free after setting it to admin pw

#

@native tide

#

You can define a trigger variable

#

So you can define the const globally

#

So like

var isSet = false;

#

If it's true , set the const adminPw

ok sure

I get

when i remove GET

dapper tusk Jul 23, 2020, 8:08 PM

well, you need to decide what should happen with the comment when the method is GET

distant trout Jul 23, 2020, 8:09 PM

I want to make it so after a user wrote a comment and press submit, it adds it to the database and displays the data on the current page.

I think i need a second route for each task

dapper tusk Jul 23, 2020, 8:10 PM

then, when you see method GET, you need to get the comment from the db and display it in the template

uncut finch Jul 23, 2020, 10:40 PM

#

Hi is anyone know, how to transfer my django project to another computer?

acoustic oyster Jul 23, 2020, 10:57 PM

#

@uncut finch I store my Django projects as private Repos on Github. Make sure you are using a virtual environment and store the requirements in a requirements.txt file along with your project.

on the command line/terminal:

pip freeze => requirements.txt

You could also simply use some sort of cloud service (i.e) google drive, or just email the project folder. You would likely need to zip the folder to avoid any issues, and just to be practical.

Transferring is as simple as:

create a virtual environment, save the required modules using pip freeze into a .txt document in the project folders.
Transfer the project folders to another computer using whatever means you prefer
Create a virtual environment on the new machine, activate the environment, and run pip install -r requirements.txt

uncut finch Jul 23, 2020, 10:57 PM

#

Thank u, I'll try 🙂

acoustic oyster Jul 23, 2020, 10:58 PM

probably, what is the issue exactly?

@native tide

#

I mean, can you provide more detail?

I'm trying to use list comprehension to generate labels in Dash Plotly, but I keep getting this error:

The children property of a component is a list of lists, instead of just a list. Check the component that has the following contents, and remove one of the levels of nesting:

Code:

@app.callback(Output('weather_page_layout', 'children'),
             [Input('daily_update_interval', 'n_intervals')])
def updateWeatherPage(input_data):
  with open('weather/fc.json', 'r') as f:
    fc_data = json.load(f)  
    weather_page = html.Div(
      children=[
        html.H1('Weather Forcast'),
          dbc.Col(
            children=[
              [dbc.Label(f"{k} - {v}") for k,v in i.items()] for i in fc_data
      )    
    ]
  )

#

Anyone know what I'm doing wrong here?

#

I've tried encasing that entire comprehension in brackets as well, but same issue

acoustic oyster Jul 24, 2020, 1:54 AM

#

That error is telling you that it cannot accept a 2D List, you are creating a List (children) of lists.

perhaps it is supposed to be

children = [dbc.Label(f"{k} - {v}") for k,v in fc_data.items()]

#

it may be easier to try this outside of comprehension first, since this is a semi-complicated loop

sly vessel Jul 24, 2020, 1:56 AM

#

I've tried that way as well. Also, I've ran through the loop with a traditional nested for loop and it runs fine

acoustic oyster Jul 24, 2020, 1:57 AM

#

the issue right now is that children == [[f"{k} - {v}", f"{k} - {v}", f"{k} - {v}"], [f"{k} - {v}", f"{k} - {v}", f"{k} - {v}"], [f"{k} - {v}", f"{k} - {v}", f"{k} - {v}"]]

sly vessel Jul 24, 2020, 1:57 AM

#

The problem is fc_data is a list of dictionaries too

acoustic oyster Jul 24, 2020, 1:58 AM

#

something like this^
when it is expecting a 1 dimensional list, yeah, I see that. I see what you are trying to do, but the way you are doing is creating arrays inside of arrays, when you need to append to a single array

#

It might make more sense to do it traditionally for readability. Since it makes sense to append here. If you give me a sec, I can create a list comp maybe

sly vessel Jul 24, 2020, 2:01 AM

#

I tried doing it traditionally as well, but because the syntax and formatting of the dash components, i keep getting a syntax error

acoustic oyster Jul 24, 2020, 2:01 AM

#

what does fc_data look like?

#

something like this?

📎 unknown.png

sly vessel Jul 24, 2020, 2:02 AM

#

Abbreviated version:

[{'Temp': '20', 'Humidity': '30'}, {'Temp': '20', 'Humidity': '30'}]

acoustic oyster Jul 24, 2020, 2:02 AM

#

kk, lemme see

#

def clean_data(data):
    out = []
    for item in data:
        for each in item:
            out.append(f"{each} - {item[each]}")
    return out

sly vessel Jul 24, 2020, 2:08 AM

#

So someone else in a different channel said to use this:

[dbc.Label(f"{k} - {v}") for i in fc_data for k,v in i.items()]

and it seems to have worked

acoustic oyster Jul 24, 2020, 2:08 AM

#

I mean, this is the non comprehension way

#

oh nice haha

#

yeah, very nice

sly vessel Jul 24, 2020, 2:08 AM

#

Which is basically just reversing what I had already

acoustic oyster Jul 24, 2020, 2:08 AM

#

dang it, they beat me to it

sly vessel Jul 24, 2020, 2:09 AM

#

I'm still not sure why that works and my original way didn't

#

For example, I thought this:

[[print(f"{k} - {v}") for k,v in i.items()] for i in fc_data]

was equivalent to this:

for i in fc_data:
  for k,v in i.items():
    print(f"{k} - {v}")

acoustic oyster Jul 24, 2020, 2:14 AM

#

yours creates two lists, since you have two sets of [[]].

yours creates a new list for ever single "i"

theirs creates ONE list with two "layers" of comprehension
rather than creating a list [f"{k} -{v}"] for every "i" theirs creates just f"{k} -{v}" for every "i" by creating "i" then looping through the items.

While yours does this, if you print the output, you should see that every f"{k} - {v}" will be wrapping in extra []

#

Yours is actually equivalent to

for i in fc_data:
  for k,v in i.items():
    print([f"{k} - {v}"])

sly vessel Jul 24, 2020, 2:16 AM

#

Ah, I see. So for comprehensions the inner loop needs to follow the outer loop as you type it?

acoustic oyster Jul 24, 2020, 2:16 AM

#

this is the same as the different of
string = "I am a string"
vs
string = ["I am a string"]

#

it depends on what you are trying to do

sly vessel Jul 24, 2020, 2:17 AM

#

Yeah, that makes sense. The part I'm curious about is why it's

[dbc.Label(f"{k} - {v}") for i in fc_data for k,v in i.items()]

instead of

[dbc.Label(f"{k} - {v}") for k,v in i.items() for i in fc_data]

#

Intuitively you would think as you read it the inner loop would come first, but I guess not

#

Well anyway, thanks the help.

acoustic oyster Jul 24, 2020, 2:53 AM

#

@quick belfry if you just mean to get specific objects by a filter, the built in method to Django would be

MyModel.objects.filter()

and specify the filters to use.

#

i.e

class MyModel(models.Model):
  modle_name = models.CharField()

quick belfry Jul 24, 2020, 2:55 AM

#

So @acoustic oyster i need not define feilds of my database anywhere?

acoustic oyster Jul 24, 2020, 2:59 AM

#

In general, Django can handle most basic DB tasks without writing any actual SQL queries.

The db fields are defined within the models

To filter things you could do:

MyModel.objects.filter(model_name=this_name)

#

^this would return all MyModels objects that have the model_name == (whatever "this_name" is)

#

and generally you would use a queryset so that you can use specific parameters to a url to search the db

#

and then render that in a view

I could also do <img src="absolute path from local drive"> but is that the way to go?

Do I have to manually add the image to my static/images folder first then do img src="url_for(static, filename=img)"?

But that means other users cant post images

hello, I've been struggling with a problem for a while now, I've started using django for school a few months back and loved it so much I continued to use it for myself, and now I'm trying to do something that I can't figure out

I was asked to make a blog to show it to the class, so I did, and I'm still working on it now, adding cool stuff over time, and now I'm trying to make a /post/last url that would always lead to the last post (so basically the highest ID in the database), so that way instead of having to remember the last ID number when sending to people I just need to send /post/last and it automatically redirects to the last post (I know it's fancy and useless but it's also because I want to put an URL to said last post at some places on the website), I've tried for 2 days and basically did everything I found on internet, but every time I end up having an issue.. I can find the last id in the db, but it's value is {'id__max': 17}, and I just need the 17, how can I do that ?

glass sandal Jul 24, 2020, 5:07 PM

Hi

flint breach Jul 24, 2020, 5:10 PM

#

oh im an idiot, my bad

native tide Jul 24, 2020, 5:10 PM

#

wait

late fjord Jul 24, 2020, 5:10 PM

#

Do you guys have any experience on freelancing with django

flint breach Jul 24, 2020, 5:10 PM

#

you reversed it, then picked the first one

glass sandal Jul 24, 2020, 5:10 PM

#

XD nah np @flint breach

native tide Jul 24, 2020, 5:10 PM

#

isnt [::-1] reversing

flint breach Jul 24, 2020, 5:10 PM

#

that's least efficient

#

yea, don't do that

glass sandal Jul 24, 2020, 5:10 PM

#

@native tide Yes it is

native tide Jul 24, 2020, 5:10 PM

#

and [-1] just taking the last element

glass sandal Jul 24, 2020, 5:10 PM

#

Mhm didn't know that

#

But they're all the same anyways

#

[-1] being the efficent

#

@late fjord You need a freelancer?

grim wharf Jul 24, 2020, 5:15 PM

wait so

Does anyone know of an open sourced blog site using Django that is the most full featured Django project you know about on GitHub for anyone to study? I know that there are a million guides on how to buiild a basic Django blog. I dont really need that. I'm wanting to see the most advanced project thjere is

grim wharf Jul 24, 2020, 5:15 PM

#

model.objects.all()[::-1][0] this or what ?

late fjord Jul 24, 2020, 5:16 PM

#

no

glass sandal Jul 24, 2020, 5:16 PM

#

model.objects.last() or model.objects.all()[-1]

#

are the better choices

grim wharf Jul 24, 2020, 5:16 PM

#

ah ok

late fjord Jul 24, 2020, 5:16 PM

#

I just want to know how you can find freelancers

glass sandal Jul 24, 2020, 5:16 PM

#

Oh

#

Fiverr?

#

Upwork?

#

Freelancer.com?

grim wharf Jul 24, 2020, 5:16 PM

#

ah well I never had this error before.... "Negative indexing is not supported" lol

glass sandal Jul 24, 2020, 5:16 PM

#

Oh XD

#

Well

#

I guess it means you can't use [::-1]

#

model.objects.last() must work th

#

tho*

grim wharf Jul 24, 2020, 5:18 PM

#

yes it does, now this problem is fixed but not what's after

#

for some reason last() wasn't working when I tried using it yesterday, but I must have used it wrong

glass sandal Jul 24, 2020, 5:18 PM

#

Hmmmm

flint breach Jul 24, 2020, 5:19 PM

#

you're just looking for the object with the highest field-value?

grim wharf Jul 24, 2020, 5:19 PM

#

yeah

flint breach Jul 24, 2020, 5:19 PM

#

you don't need to use last, or first, just a lookup query

glass sandal Jul 24, 2020, 5:19 PM

#

Oh I see

flint breach Jul 24, 2020, 5:20 PM

#

Model.models.all().order_by('-field').first()

#

or more succintly, Model.objects.latest('<your-field>')

glass sandal Jul 24, 2020, 5:21 PM

#

Oh yes

grim wharf Jul 24, 2020, 5:21 PM

#

also works

glass sandal Jul 24, 2020, 5:21 PM

#

I thought he/she needed the last object

flint breach Jul 24, 2020, 5:21 PM

#

i mean technically, it is a first/last object, if you have a sorting on your models

grim wharf Jul 24, 2020, 5:21 PM

#

well I need the highest id (or primary key)

#

so yeah

#

the last

glass sandal Jul 24, 2020, 5:22 PM

#

@flint breach But it is not supposed to be the primary key

flint breach Jul 24, 2020, 5:22 PM

#

so you want litteraly, the last object that was created

glass sandal Jul 24, 2020, 5:22 PM

#

Oh so last anyways

#

Just do model.objects.all().order_by('-id').first()

#

As @flint breach said

flint breach Jul 24, 2020, 5:23 PM

#

Model.object.latest() should be alright

glass sandal Jul 24, 2020, 5:23 PM

#

Yeah

grim wharf Jul 24, 2020, 5:23 PM

#

yeah that works

glass sandal Jul 24, 2020, 5:23 PM

#

Nice

flint breach Jul 24, 2020, 5:24 PM

#

these are actually preety common problems, google should have returned some decent answers

glass sandal Jul 24, 2020, 5:24 PM

#

Yeah

#

Or even the docs

flint breach Jul 24, 2020, 5:25 PM

#

glass sandal Jul 24, 2020, 5:25 PM

#

Yeah

flint breach Jul 24, 2020, 5:25 PM

#

Learn GoogleFu, it will help you in the longrun

grim wharf Jul 24, 2020, 5:25 PM

#

what I seached

#

and tried a lot of solutions

glass sandal Jul 24, 2020, 5:25 PM

#

What did you exactly search?

flint breach Jul 24, 2020, 5:25 PM

#

django get latest object, first result was alright ;P

glass sandal Jul 24, 2020, 5:25 PM

#

Like how to get the last object?

flint breach Jul 24, 2020, 5:26 PM

#

it's fine, wasn't a problem

#

but these problems that seem like it has a common use case, im sure google returns an answer fast

#

just be specific (not too specific :P), and you'll get something outa of it

grim wharf Jul 24, 2020, 5:26 PM

#

what solution do you get ? because the one I find doesn't work... is it maybe because I'm not located in the same country ?

Apologies, I am completely new to Django and Python.

flint breach Jul 24, 2020, 5:48 PM

I guess none of the web devs changed during Quarantine

glass sandal Jul 24, 2020, 5:49 PM

hello guys , im using flask as backend for my web app and i want to implement a notification feature where a user gets notified real time when an action is taking place like that of facebook . but id like to hear some ideas from you guys on how to make this feature..

rancid fable Jul 24, 2020, 6:12 PM

#

Sometimes I wonder if I'm made for this stuff

glass sandal Jul 24, 2020, 6:23 PM

#

Ah god you have to deal with Frontend for the notifications?

flint breach Jul 24, 2020, 6:25 PM

#

Sounds like a job for either polling or websockets

safe glen Jul 24, 2020, 6:27 PM

#

@glass sandal yeah i also need ideas on how to implement it at the backend too

glass sandal Jul 24, 2020, 6:27 PM

#

Well then , ngl , idk how to do it lol

safe glen Jul 24, 2020, 6:27 PM

#

@flint breach yeah im currently researching on them rn

flint breach Jul 24, 2020, 6:28 PM

#

Polling js probably simpler to implement, but gonna be less efficient

#

Depends on what scale you planing to build

nova escarp Jul 24, 2020, 6:40 PM

Hi guys, Im trying to implement something in my Django site and not really sure where to start.
I want to take all of the instances of my model and group them based off of date and list that on a page (i.e. wed july 22 lunch, thursday july 23 dinner, etc). And have those dates be hyperlinks that take you to a view (possible detail view?) that has all of the instances of the models from that specific day. I really don’t know where to even start, Im guessing the date links will be a list view but i’m not sure where to get these dates from (I want them to appear only after an instance is created for that date). If anyone can point me in the right direction I would really appreciate it

native tide Jul 24, 2020, 7:10 PM

#

maybe make a class called event and give it a field of date and maybe event detail like lunch dinner

#

so u would only have one table
