can you explain what you mean

return render(request, "main/home.html", {}) do you mean to add this/

#

So when you are submitting this form the info are being sent to the same url of the page you're at because action is empty

marble spade Mar 27, 2021, 10:25 AM

#

right so what do I change the action to

#

oh

tribal pewter Mar 27, 2021, 10:26 AM

#

In your urls file create a new path to the view yeetman

#

And puth that path in action

marble spade Mar 27, 2021, 10:26 AM

#

but yeetman is simply a function

#

why would I need to add a path?

#

it's not a wepage

#

web

tribal pewter Mar 27, 2021, 10:27 AM

And how do you trigger that "function"

hey guys, i want to know how i can make bootstrap cards move on their own. so basically i have these cards right, and im using django to have a for loop and the amount of things Django returns is th amount of cards that are created right. so basically, if my database has 3 items, Django is going to create 3 cards, but right now it will only be created by going down. how can i set parameters to where the cards are pushed. because i want to first: check if the cards are approaching the bottom of the screen and then secondly: check if the cards are overflowing to the right. how can i add those 2 parameters to the the html so that the card divs can be placed appropriately to the resolution of the window
can you please ping me if you have a input, thank you

tribal pewter Mar 27, 2021, 10:29 AM

#

marble spade it just does

You can simply put the content of the second view in the first one in your case

marble spade Mar 27, 2021, 10:29 AM

like nested?

tribal pewter Mar 27, 2021, 10:29 AM

#

Nono

marble spade Mar 27, 2021, 10:29 AM

#

or just remove the function

#

not needed

Q) What do y'all think about Serverless Flask? Is it a good implementation?

opaque halo Mar 27, 2021, 12:14 PM

#

Hi guys! I was wondering if either of you could point me in the right direction as my current project isn't in my area of expertise.

I store my (anime)series' ratings on an online database (and have access to their API) -I need to re-rate most of the series as most of my tastes have changed over the past 3 years.

I wanted to build an web/or any other interface to help me rate these at speed (using my keyboard only). I was initially thinking of doing this using pygame? Since that's the only GUI library that I have somewhat experience with.

But I was wondering if you guys knew of any other "easier" or elegant way I could get this interface setup quickly.

My main area of comfort in Python is data science, so this just feels quite daunting to me :S

past cipher Mar 27, 2021, 2:08 PM

#

Would you say its quicker to loop over 10,000 rows than delete 10,000 rows from a database ?

#

the row contains two columns: ID, Item

#

The problem I'm facing is user can create a product, and sell items. they could add 10,000 items for example. When they update the items, I need to compare the new items vs the old items, and update the items inside the db

#

i'm stuck on whether to just delete all the rows, and then add the new items

#

or compare the two lists, and then add rows to the table that don't exist already

opaque halo Hi guys! I was wondering if either of you could point me in the right direction ...

i've not used it with pygame, but you could do this quite simply with javascript/html. You could make an API call loading a series, listen to key presses (1,2,3,4,5) for stars, and once the user clicks a button, make an API call back to your server to update the row in the database. Then just repeat 🙂

Sorry this is in French but I am sure you can identify which error it is in english

#

yes correct

#

by the way, I am on "Strict mode" for Firefox, could it be the issue?

opaque rivet Mar 27, 2021, 3:07 PM

#

not sure - but that error is due to your CORS enforcing the same origin policy, the origin of that request is not included in the CORS settings. (which is strange, as you've specified the settings are fine).

weak mesa Mar 27, 2021, 3:09 PM

Yes, considering it is working on chrome and edge, this is quite strange indeed

or https?

#

http

#

it is written https on the error though

opaque rivet Mar 27, 2021, 3:13 PM

#

hmm... I sense that may be an issue that trips CORS, since they're different protocols & therefore different origins.

#

you could try use ngrok to quickly get https for your site (if it's running on localhost) then retry

weak mesa Mar 27, 2021, 3:14 PM

React app is running on my machine (localhost) and the DRF API is running on aws ubuntu server

I will check on aws how to get https protocol for my instance

opaque rivet Mar 27, 2021, 3:17 PM

it will be your frontend which will have to utilize https, i'd recommend ngrok for that. I'll admit that's a strange error though 🥴

It will look slightly different, but it tells what the error means

azure flax Mar 28, 2021, 1:31 AM

#

how can i got the logs? (i am not too much used to use django since i use it just for the django-admin panel) all the logs i can have is from my docker

#

maybe i have to execute a command on the docker of admin?

opaque rivet Mar 28, 2021, 1:39 AM

#

azure flax what do you mean please?

What's your error message?

My guess would be that the error lies in the setattr functions (which I would avoid using, by the way) - but we're going to need the error message.

azure flax Mar 28, 2021, 1:40 AM

#

where can i see the error message, because my runserver didn't return any error

#

i only got it with the interface on the debug mode

#

and my message error is "can't set attribute"

opaque rivet Mar 28, 2021, 1:45 AM

#

azure flax Hello everyone, i am using pre_save signal to change the path of the files that ...

oh, I found your error, here it is:

setattr(instance.picture,"url",'media/{}'.format(instance.picture.url))

and

setattr(instance.picture,"url",'media/{}'.format(instance.picture.url))

Firstly, I would not use setattr. The first line is equal to saying:
instance.picture.url = media/{}'.format(instance.picture.url) which is better in terms of readability.

the url of your picture is read-only, you cannot set it.

azure flax Mar 28, 2021, 1:47 AM

#

so how can i set it? the problem is my media are in the folder media/.... and when i set it on the settings.py, so to save in the database the url as media/... not only the_path_to_picture that's why i am trying to do it like that

#

do you think there is a way to update the "url" on my database

opaque rivet Mar 28, 2021, 1:53 AM

#

I don't know what you're trying to do. I would give instance a new picture and then use that url for whatever you're using it for...

azure flax Mar 28, 2021, 1:53 AM

#

I will explain my problem, maybe there is a simple solution than doing it with 2 signals haha!
my problem is that i save my medias on the media/... folder i defined on the settings by MEDIA_URL = '/media/' , so everytime my Imagefield save a new picture it stores it to media/path_specified_in_Imagefield, but i would like to save the data on my database with directly the true path to my pictures and by that i mean media/path_to_picture

opaque rivet Mar 28, 2021, 2:03 AM

#

I don't really work with media files that much, but could you change your picture's name to its url? Pretty sure the name is not read-only like url. That way your files will have their urls as their names - with some trimming down of the path that is

opaque rivet Mar 28, 2021, 2:24 AM

#

azure flax so how can i set it? the problem is my media are in the folder media/.... and wh...

also I don't understand why you'd want to do that in the first place, doing:
setattr(instance.picture,"url",'media/{}'.format(instance.picture.url))
would give your picture the wrong url and serve nothing in benefit. Just change the name of the picture instead and don't worry about it.

hey guys, i want to know how i can make bootstrap cards move on their own. so basically i have these cards right, and im using django to have a for loop and the amount of things Django returns is th amount of cards that are created right. so basically, if my database has 3 items, Django is going to create 3 cards, but right now it will only be created by going down. how can i set parameters to where the cards are pushed. because i want to first: check if the cards are approaching the bottom of the screen and then secondly: check if the cards are overflowing to the right. how can i add those 2 parameters to the the html so that the card divs can be placed appropriately to the resolution of the window
can you please ping me if you have a input, thank you

What's the testing methodology?
Do you run all get/post requests with mock-data?
Do you check the response codes only or do you also check if the desired output is received? If yes, do you call an instance of the function that converts input to output, in the test to check if the response matches

opaque rivet Mar 28, 2021, 10:26 AM

#

ashen vigil What's the testing methodology? Do you run all get/post requests with mock-data?...

yeah, I'd test my models / classes and test that the output is what I expected, you would repeat this until you think you've covered most bases with your models.

#

same thing goes for API endpoints, just test everything

as python is inherently slow at serving static content.

#

and to be fair, i googled every error and managed to work things out

and when configuring whitenoise, add the middleware to settings.py:

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'whitenoise.middleware.WhiteNoiseMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',

wooden ruin <@!646078090161815552> lets say you have a SQL database full of all sorts of dat...

ok

wooden ruin Mar 28, 2021, 5:17 PM

#

you cant just access it by messing around, if you want to access it you have to write a sql command. sounds fair?

#

you can automate this by using flask, for example

#

you can write some code in python that will access the database and do whatever you want

#

but lets say someone else doesnt know any python or SQL

#

how would they get something from the database? well they could talk to you

#

if i tell you to get me a picture of a dog from a database, you could do that using flask, django, sql, etc. right?

#

i dont even need to know python, as long as you can take care of it for me

#

and you can "do your thing" and return to me the picture of a dog

#

i don't have to know anything that you are doing as long as i know how to talk to you

#

that how i like to think an api works

#

and if you can provide me with consistent pictures of dogs, then i can rely on you to build a dog website, for example

#

so if a user were to visit my website, i would "ask" you to give me dog pictures, and you would return pictures of dogs for my to display

#

did this clear anything up? @mystic wyvern

to some extent yes

            console.log("data received")
            console.log(data)
        }

The websocket is accepted by my server, and I send back a response (w/ key "text")

# consumers.py
    def websocket_connect(self, payload):
        self.send({
            "type": "websocket.accept",
            "text": db.get(all_keys=True)
        })

But my JS onmessage function isn't recognizing it. Can I not send data payloads when accepting websockets? I guess the connection is not yet established completely so I won't be able to send data like that?

naive sparrow Mar 28, 2021, 6:15 PM

@opaque rivet did you include websocket cdn

#

Check console if there's any errors or warnings

opaque rivet Mar 28, 2021, 6:18 PM

#

naive sparrow <@812098613450506351> did you include websocket cdn

no, I'm using django channels but my websockets are connecting fine. I think the issue is that you just can't send a payload when accepting a websocket connection.

naive sparrow Mar 28, 2021, 6:19 PM

#

Sorry can't help with Django, i'm javascript dev :)

opaque rivet Mar 28, 2021, 6:20 PM

#

gotcha, I'll just have to read about them a bit more, I think I'm onto a workaround though, I'll see if it works ~5mins

#

ws.onopen = () => {
            ws.send(websocketEnum.Initialize)
        }

ok works now :),

websocket request is sent to server,
server sends a response accepting it,
client sends a request saying "I'm ready"
backend sends required data

    def websocket_receive(self, payload):
        if payload['text'] == 'initialize':
            self.send({
                "type": "websocket.send",
                "text": json.dumps(db.get(all_keys=True))
            })

#

thanks for the help 🙂

wooden ruin Mar 28, 2021, 6:31 PM

opaque rivet no, I'm using django channels but my websockets are connecting fine. I think the...

from my experience you can only send certain things. if i ever need to send JSON back to the websocket, i just use JSON.stringify in javascript, then just use json.loads in the consumer. are you using WebsocketConsumer for your class?

opaque rivet Mar 28, 2021, 6:32 PM

#

wooden ruin from my experience you can only send certain things. if i ever need to send JSON...

yes, using SyncConsumer

#

but it leads me to another question

#

for RESTful APIs, you can have multiple functions in one (e.g. handling GET, POST etc.) - is it the same with websockets? it seems like each websocket endpoint can only do one function, unless my frontend is sending some sort of status message like "update", "initialize", etc. does that make sense? how is it done usuaully?

wooden ruin Mar 28, 2021, 6:37 PM

#

since we are dealing with non-http here, it's difficult to imitate other methods. look into socket.io if you want to have more custom events such as emit. as for now, my go-to is to have 1 consumer method that receives any messages, looks for a status in the body and redirect to the appropriate function. it's not the ideal setup but it keeps things semi-organized, and i can always split the websocket into 2 separate routes if i need to

opaque rivet Mar 28, 2021, 6:40 PM

#

ok cool, websockets are looking nice so far 🙂

#

definitely going to use em for future projects

wooden ruin Mar 28, 2021, 6:41 PM

#

absolutely! also, look into django signals as well. when paired with django channels, it's a really cool and powerful combo :)

opaque rivet Mar 28, 2021, 6:45 PM

#

mhm, working on redis-specific signals atm and hopefully I'll be able to send frequent updates from the server

opaque rivet Mar 28, 2021, 7:36 PM

#

wooden ruin absolutely! also, look into django signals as well. when paired with django chan...

hmm so on the topic of signals... for example on post_save (or similar), would you send a signal within a channel group to send an update to every client in that group?

wooden ruin Mar 28, 2021, 7:36 PM

#

yep, to me it's a great usage for broadcasting events

#

so if a new user is registered you can display it live

#

so new users can kind of see how "active" it is? if that makes sense

#

it would also be a good idea in terms of web gaming or, more importantly, database verification

#

saves time instead of processing everything in one view per request

opaque rivet Mar 28, 2021, 7:38 PM

#

ah I see. I haven't yet learnt about channel layers / groups, and I was trying to listen to redis updates within the syncConsumer itself 🤦‍♂️ , but I think channel layers is what I need.

essentially just need the signal to push data to the client via the websocket, to all clients connected to the "channel". will channel layers solve this?

wooden ruin Mar 28, 2021, 7:41 PM

#

channel layers allow you to group your consumers, such as with chat rooms: if youre in a chat room, you can't see the messsages of another one. for this one you won't even need channel layers. or, you can put every user into 1 big channel layer and broadcast to that layer whenever you recieve the signal

#

unless, you are grouping your clients somehow, maybe based on authorization/access or any factors really

opaque rivet Mar 28, 2021, 7:43 PM

#

all my clients should be grouped together in one pot.
so by my understanding, I can register all the clients to a channel layer and then broadcast data to all of them at once?

wooden ruin Mar 28, 2021, 7:43 PM

#

yep, using the self.channel_layer.group_send method

#

it's going to need a workaround, though, because you need a staticmethod to connect if you're using django signals

#

    def get_user_updates(sender, instance, **kwargs):
        try:
            name = instance.first_name + " " + instance.last_name
            i = UserConsumer.connected_users[0]
            async_to_sync(i.channel_layer.group_send)(
                i.name, 
                {
                    "type": "message",
                    "message": name + " has registered for an account!"
                }
            )
        except: pass

this was my implementation of this

opaque rivet Mar 28, 2021, 7:46 PM

#

i wont be using the django signals, but something similar (for redis). I'll just need to broadcast based off a conditional:

  if i_need_to_update_client:
    layer.broadcast...

^ something like this

#

big thanks for the help!! I was trying to implement channel layers without knowing what they were, I really appreciate the explanation 🙂

wooden ruin Mar 28, 2021, 7:48 PM

#

no problem! i know this stuff was difficult for me when i first started, so i know how it feels

#

as a last note before i have to go, do note that the redis signal function you might be implementing can't really know whether to send it or not, such as if no users are connected. it's best to keep track who and which users are active, and I store them in a list, and remove them fromthe list when the client disconnects. that way i have all my users in a list ready to go, and i can message any one of them should i need too

Following django doc (https://docs.djangoproject.com/en/3.1/topics/http/shortcuts/#django.shortcuts.render)

Django shortcut functions | Django documentation | Django

#

It should be msg/index.html

#

But since you created a directory

#

Should it be msg/msg/index.html?

opaque inlet Mar 28, 2021, 11:18 PM

#

I don't believe so

I went to the directory that django was looking for and I don't see a msg app there

wooden ruin Mar 28, 2021, 11:41 PM

if you are able to get a guild's id within the function, then all u have to do is query your database for the guilds id

wooden ruin Mar 28, 2021, 11:44 PM

start by planning out your table - plan out every field per row, and what kind of fields they will be. then you can query a guild by its id, name, etc.

how what? using jinja2 templates? It would be much more readable & you should definitely use them, they give you more flexibility.

you don't want to have to be opening html files and writing stuff to the end of the file

thats true

opaque rivet Mar 29, 2021, 11:19 AM

with jinja2 templates you can have for loops, conditionals, and you can extend other templates... Overall it means you write much less HTML, and it allows you to easily communicate with your view

why does my modal not show its contents?

dbc.Modal(
            [
                dbc.ModalHeader("Header"),
                dbc.ModalBody("This is a modal "),
                dbc.ModalFooter(
                    dbc.Button(
                        "Close", id="close-centered", className="ml-auto"
                    )
                ),
            ],

Try css grid containers

Or inline-block

Hey I am looking into deployment my first Flask app, if I choose to use PostgresQL do I need to host it on a different server from where I host the Flask app?

You can use heroku

#

they give u a free postgresql database

#

and free 500 hrs worth of hosting time every month

Thanks! I'm guessing that Heroku is beginner friendly?

Don't know much about it.

native tide Hey I am looking into deployment my first Flask app, if I choose to use Postgres...

you can run them on the same server just fine

#

often most thinks like this will run them together unless your a large company scaling across multiple servers

native tide Thanks! I'm guessing that Heroku is beginner friendly?

it was pretty beginner friendly for me.

theres just the whole file

quick cargo Mar 29, 2021, 3:33 PM

#

what you can do that might work

#

is import asyncio

#

get a event loop at the top of your file just after the imports

#

e.g.

#

loop = asyncio.get_event_loop()

#

then pass app.run() loop=loop

#

so that it forces quart to use the given event loop rather than what it does by default which is create a new one

elder nest Mar 29, 2021, 3:35 PM

ok

quick cargo Mar 29, 2021, 3:35 PM

that should? fix it, otherwise you might need to give motor a explict loop kwarg

quick cargo Mar 29, 2021, 3:41 PM

It's not quite that simple because it's a promise

        const props = this.state
        const obj = this.state.jsonData
        const array = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]

How should i go about implementing authentication in my frontend and backend?

quick cargo Mar 29, 2021, 5:51 PM

#

What sort of auth and what for?

#

like API auth, or general user login stuff

serene prawn Mar 29, 2021, 5:52 PM

#

User login, but basically it would be an api auth too 😅

#

Because you need to access application api from frontend

quick cargo Mar 29, 2021, 5:52 PM

#

Hmm, well i think the best sort of setup for that would probably be Oauth2

#

as it makes sure you follow a fairly secure setup and minimizes the risk of something going wrong

#

its basically the concept of

#

user sends a request with a given auth method, this can be username and password in cases

#

server validates this data

#

and returns a Token

#

and any interactions the user does go through the token

#

that token automatically expires after a given time unless it's renewed

serene prawn Mar 29, 2021, 5:54 PM

#

I don't really want to use oauth because it looks complex though.

quick cargo Mar 29, 2021, 5:54 PM

#

what framework / lib are you using for your backend?

serene prawn Mar 29, 2021, 5:55 PM

#

I work with laravel and use django occasionally

quick cargo Mar 29, 2021, 5:55 PM

Django has a really good Oauth lib pre made

#

that does all of the hard work for you

#

I imagine laravel will as well because it's the Django of PHP lol

quick cargo Mar 29, 2021, 5:56 PM

#

https://new-django-oauth2.readthedocs.io/en/latest/getting_started.html is the Django oauth2 stuff

#

nice lib overall and makes it very easy

#

if you want something a little simpler you can go with the sort of default user name and password type deal but generally i recommend against it because it can be less secure

serene prawn Mar 29, 2021, 5:58 PM

Btw is there application level middlewares in django?

serene prawn Mar 29, 2021, 5:59 PM

I know you can decorate your view with middlewares tho

quick cargo Mar 29, 2021, 6:00 PM

hey, i'm using flask and I'm having trouble returning json data to an ajax call without changing the page. when I return the json it just displays as text on the page. code screenshots to follow...

#

#

#

#

any help would be greatly appreciated, ive tried using different methods of returning the json but i cant get it working

quick cargo Mar 29, 2021, 6:32 PM

#

i believe you can just return the dict as normal instead of jsonify now

hardy cosmos Mar 29, 2021, 6:32 PM

#

that still has the exact same result 😦

quick cargo Mar 29, 2021, 6:32 PM

#

can you send a SS of the headers it's returning

hardy cosmos Mar 29, 2021, 6:32 PM

#

yep

#

this is all its returning

#

so its like the json isnt being returned correctly its just being dumped as text

quick cargo Mar 29, 2021, 6:33 PM

#

hmm

#

and ajax cant handle this using JSON.parse() ?

#

oh well looking at your ajax code it seems you're just reading the JSON as a string anyway

#

so it makes sense that it's displaying it like that

hardy cosmos Mar 29, 2021, 6:35 PM

#

how do i parse it in not as a string?

#

sorry im a web design noob

quick cargo Mar 29, 2021, 6:35 PM

#

you need to do let foo = JSON.parse(text) to convert it to a JSON object

#

thanks, one sec ill try that

#

hardy cosmos sorry what do I need to pass in as the argument to parse <@!290923752475066368> ...

you need to parse the response text

#

note that if you're just displaying this to some html element it's gonna look like text not json

hello guys, Im a python beginner and im interested in learning Django for making Webapps but I also heard about Flask. Does someone know if Django and flask are made for different purposes ?

quick cargo Mar 29, 2021, 6:45 PM

#

they both achieve the same goal just in diffrent ways

do you mean that it's still looking like a string?

hardy cosmos Mar 29, 2021, 6:50 PM

yeah so my intention is to take the response and use it with javascript to modify text on the page, but instead flask is just sending me to a blank page with the json printed out as plaintext

what does console.log(text) do

quick cargo Mar 29, 2021, 6:51 PM

#

you should note that anything which isnt a direct JSON response from the server wont have the browser lint it

#

your browser will only pretty print json like that if it's the direct response

#

what you have going on is dynamic where the main webpage is HTML so the browser is going to display it like HTML

#

if you're just trying to display the returned json then it is going to look like text because the browser isnt going to pretty print it like you would expect from a direct JSON response

quick cargo Mar 29, 2021, 6:52 PM

can you send a SS of your terminal with what it prints

I am new to #Django-rest-Framework. I am trying to create a public POST api and on display it should also have the HTML form like it does with the class based views.

Here is my view.

@api_view(['POST'])
@permission_classes([permissions.AllowAny, ])
@authentication_classes([])
@renderer_classes([JSONRenderer, BrowsableAPIRenderer])
def lead_create(request):
    serializer = LeadSerializer(data=request.data)

    if serializer.is_valid():
        try:
           serializer.save()

        except Exception as e:
            return Response(
                str(e),
                status=status.HTTP_400_BAD_REQUEST
            )

        return Response(
            {'message': 'Lead Successfully Saved'},
            status=status.HTTP_201_CREATED
        )

My problem is the output is something like below:

After writing my first website with Django, I am looking into learning Node for a potential job. Only basic JS knowledge so far, but not new to programming. My idea was to create a tinder clone as my first project, but I am unsure about the technology to use.
MERN/MEAN/MEVN stack sound like what I should be heading for, with MERN>MEAN as Angular to me seems like it has a high learning curve. Not sure about Vue.
I am also unsure about the advantages of Mongo - being somewhat experienced in Postgre, PERN also seems like an alternative.

Also thinking about using Firebase, but I am unsure about GDPR regulations (and Tinder-Data is intimate data, so I guess GDPR applies more heavily?). For my Django Project I used Heroku and AWS S3 for deployment.

Thanks for your time

hi! i want to make a button that adds a new <entry> on the page. how would i do this in flask? do i need to use JS or can i use jinja?

#

my backend is written in flask

serene prawn Mar 29, 2021, 8:07 PM

#

If you want to persist that data then you would have to save it on your backend

#

If you just want to add the element then just do that with js

sand glen Mar 29, 2021, 8:09 PM

thing is

#

i dont know how

#

jquery?

serene prawn Mar 29, 2021, 8:10 PM

If you're pretty new to js then learn how to insert new elements into dom

sand glen Mar 29, 2021, 8:11 PM

i have never used JS before

#

in my project i have python, CSS and HTML only

serene prawn Mar 29, 2021, 8:11 PM

You can either use native js or jquery but for anything more complex I would use js framework 😅

sand glen Mar 29, 2021, 8:12 PM

like react?

#

can i use react with a python backend

serene prawn Mar 29, 2021, 8:12 PM

#

You can

#

There's also vue and angular

#

They are more like frameworks when react is a library

#

But react and angular have better typescript support

sand glen Mar 29, 2021, 8:14 PM

#

isnt typescript only useful backend

#

also

#

arent those JS libraries way better if you use JS backend

serene prawn Mar 29, 2021, 8:14 PM

#

It's not

#

And you can use any backend

sand glen Mar 29, 2021, 8:15 PM

if im going to use react

#

should i ditch bootstrap

serene prawn Mar 29, 2021, 8:15 PM

#

Plus typescript can be useful anywhere

#

Use bootstrap if you like it

#

There should be a react library with bootstrap components or you can just do that with classes

sand glen Mar 29, 2021, 8:18 PM

#

so all i need to do is add react to my <head> and i can use it

serene prawn Mar 29, 2021, 8:19 PM

IEX cloud is a great API for that sort of thing, the rate limiting is quite loose so you can get away with making a request every minute on the free plan.

opaque rivet Mar 29, 2021, 9:30 PM

#

sand glen i already have an app though

if you're using React, the frontend is independent of your backend. You'll just use Flask as an API and have your React app as a SPA (single page application - this means that your server just renders 1 page and all of the future rendering of components is done by the client) - unless you use server side rendering but that's a bit more complex.

by doing create-react-app you will make a new folder where you can create your frontend.

how do i access my state inside onload event listener of xhr?

#

    at XMLHttpRequest.xhr.onload (DemoBox.js:157)```

opaque rivet Mar 29, 2021, 9:33 PM

#

sand glen should i ditch bootstrap

also, you still have to write HTML with React, so bootstrap is can still be used - but you can also use UI libraries (ant design / chakra UI) to speed up your frontend development.

if you don't know JS you should learn it before learning react.

is it possible to make a web site with python

or is html better for that

dusk yoke Mar 30, 2021, 12:17 AM

#

@velvet crystal I think HTML is for front-end and Python for back-end, so you would need both.

Hi, does anyone know where I can host a Flask app online for free? I heard of Heroku and Netlify, do they work? Do they require any credit card details

mint hedge Mar 30, 2021, 3:59 AM

#

I am writing a calculator flask app to calculate current draw for certain devices. Each has a set value but could change as updates to the devices occur (more or less current). I wrote a desktop version of this app and used a json file for all the values based on their settings (each device has about 5 different settings that determines the current draw).
I would like this easily editable by either a normal person or a simple IT person.
My question is, should I stick with json as my “database” or move over to something like SQLite?

Is Pythonanywhere free? Do I need a domain?

mint hedge Mar 30, 2021, 4:03 AM

It is free for one site. They make the domain for you. Say you used you screenname, it would be www.donald@pythonanywhere.com or something like that

It is great for testing

If you used a pi, check out noip. It helps set up a domain and add a layer of security

#

And if you are afraid of being hacked, plug it in at the library 😂

#

Thanks! Do alternatives such as heroku or netlify work? I have seen people use those for hosting side projects

mint hedge Mar 30, 2021, 4:06 AM

#

No idea.

#

I bug my sys admin at work with these questions

#

I am apparently on the IT dept’s watchlist

#

Because “linux bad!” And I know what a raspberry pi is and the furthest extent to the knowledge my IT manager has is by watching Mr. Robot

#

I am not too smart in networking. I know the basics. I am more a desktop guy myself.
My IT dept keeps making us watch videos from Kevin Mitnick's company and he shows how he can hack a mac to get the keychain password through an email. He never shows HOW he does it though (code or anything). I am not looking to hack people but i find the concept fascinating and want to see the methods used.......... yea, maybe i should be on the watch list

#

anytime someone at work leaves their computer open when they walk away, I open notepad and type "Thanks for the info"

#

I even got my IT manager one time. That was awesome

#

for him, i wrote "now I have the keys to the kingdom!"

@daring cairn have you tried adding <string:self> to the URL decorator so that it is like @app.route ('/<string:self>'). But why are you passing self? You don't seem to be using it in that function.

is it possible to make the navbar one file with html

#

instead of putting it on the top of every pages code

#

it would make it easier to edit but im not sure if i can do it with html

#

you wouldn't want to do that what I would do is make an index with all of your basic stuff like navbar and text stuff and then use that as the base of your website

#

does that make sense?

#

not really to me

#

liek do u mean for the mains ite

#

because it has multiple pages

#

this is the main page

#

here what exactly are you working on? is this for school or for someone else or just personal

#

just for fun

#

its jsut a site im showing my friends and making it for fun

#

Dope I have been doing Web dev since I was 12 do you want me to become your tutor I could teach you all of this stuff

#

this is what i mean by maybe having the navbar as one file so if it breaks i dont have to edit the pages

#

if you want

#

ive been messing with sites and jsut code stuff since 2018

#

but i started actual knowing how to do it in 2020

#

in 2018 and 2019 i didnt understand it so im not really good

#

I could teach you how to write this and so you could start doing web dev for other people in like 3-6 months

#

if you want you can

#

i dont really know php good

#

im better with html stuff

#

ok do you want to dm me?

#

alr

ill dm

what's the difference between name of web page

#

and name of web site

proper hinge Mar 30, 2021, 6:42 AM

#

A site is made up of one or more pages

#

Think of it like book title (site) vs chapter title (page)

native tide Mar 30, 2021, 7:25 AM

#

native tide is it possible to make the navbar one file with html

Not exactly. But you can do something even better than that if you use Jinja2 templates for your HTML.

what does child and sibling meaning in css when refering to selectors?

inland stirrup Mar 30, 2021, 7:46 AM

#

The child combinator (>) is placed between two CSS selectors. It matches only those elements matched by the second selector that are the direct children of elements matched by the first.

The general sibling combinator (~) separates two selectors and matches all iterations of the second element, that are following the first element (though not necessarily immediately), and are children of the same parent element.

coarse egret what does child and sibling meaning in css when refering to selectors?

<section>
    <div>
        <time></time>
    </div>
    <img>
    <a></a>
</section>

#

section time (descendant) selects time
section > time (direct descendant) selects nothing
div > time selects time
div + a (immediate sibling) selects nothing
div ~ a (sibling) selects a
img + a selects a

What should my query be for getting all the objects related to a manytomany field that is bid in the above example

inland stirrup Mar 30, 2021, 7:48 AM

vestal hound `section time` (descendant) selects `time` `section > time` (direct descendant) ...

you mean like...Category.bid.all()?

inland stirrup Mar 30, 2021, 7:49 AM

#

...if i do that will i get all the objects of Listing table?

vestal hound Mar 30, 2021, 7:50 AM

#

wait

#

do you want the Listing

#

or the Category

inland stirrup Mar 30, 2021, 7:51 AM

#

i want listing but from category

#

like if i want to get all the listing that are in a category

vestal hound Mar 30, 2021, 7:51 AM

#

then it is as I said

#

why

#

is your attribute called bid

inland stirrup Mar 30, 2021, 7:51 AM

#

vestal hound Mar 30, 2021, 7:51 AM

#

but your model called Listing

native tide Mar 30, 2021, 7:51 AM

#

@native tide i was able to do it

vestal hound Mar 30, 2021, 7:52 AM

#

inland stirrup

as in

#

for a category object

#

so more accurately category.bid.all()

native tide Mar 30, 2021, 7:52 AM

#

i jsut made the html file a php one and left my original code and put at the top a php include

then included the nav bar
