oh and that as well, the amount of files you need to download

wicked elbow
#

react and redux are both easy. i learned django, rest framework, react and redux all at once. that was definitely a fun process, but after the first run through its increadibly simple

serene prawn
swift wren
#

even tho its lik 2 commands, the amount of files it downloads is jsut horrific.

#

really?

serene prawn
#

They're all cool but angular and django come with batteries

gloomy osprey
#

NOT NULL constraint failed: MyServer_links.redirect_url

swift wren
#

flask would be react right?

serene prawn
#

Yep

swift wren
#

yeah seems why i like it more

#

i tried angular and i hated typescript

wicked elbow
#

no flask is backend react is front end....

quick cargo
#

KannaWhat jinja is nothing like react

swift wren
#

...

serene prawn
swift wren
#

really?

quick cargo
#

CS rendering is was diffrent than SS rendering

serene prawn
#

Not cs and ss rendering

swift wren
#

its legit a abstract comparision are you lot alrigh?

gloomy osprey
#

pls help me

swift wren
#

i think its because of the fact that im very old fashioned that i like python and c based programming paradigms and i dont really like new ways of programming languages, thats why me and js have a bad relationship

#

@gloomy osprey yeah go

quick cargo
swift wren
gloomy osprey
#

line 82

swift wren
#

nah bud, if you have a not null constrain on your field, then if you left it empty its gonna cause issue

wicked elbow
#

flask django dont compare to react at all... angular either for that matter. front end vs backend data manipulation.

gloomy osprey
swift wren
#

yeah they do

quick cargo
swift wren
#

flask is a library, django is a framework

quick cargo
#

Errr not quite

swift wren
#

its mysql, its web based im pretty sure

quick cargo
#

Ehj?

wicked elbow
#

no... flask and django are both just like php and asp

gloomy osprey
wicked elbow
#

they are backends... thats all they are

swift wren
#

no shit bro are you high?

#

go and carefully read what was written

#

you are missing the point

quick cargo
#

Mysql isnt web based

#

You're just spurting nonsense lol

wicked elbow
#

no im not... your comparing apples to oranges

swift wren
#

@serene prawn help pls

serene prawn
#

???

quick cargo
#

That key wont exist in headers

#

So it's returning null

serene prawn
quick cargo
#

Man's arguing that flask and every other micro framework isnt a framework

swift wren
#

wha??

quick cargo
#

As well as Mysql apparently being web based 🤣

wicked elbow
#

flask and django can both be ran by themselves. same with php and asp and any other backend languages. react can be ran by itself for a lot of things front end. angular has built in support for stuff that react doesn't but doesnt mean its required for it to work

swift wren
#

flask is a lib, django is a framework. react is a lib, angular is a framework. there are meta similarities, i'm doubting if you can read honestly

quick cargo
#

Flask is a framework

#

A library generally refers to the fact that it requires no set layout or way of doing things to be able to use it, flask has those requirements, just because it doesnt do the mass auto file generation that django does, doesn't make it not a framework

serene prawn
quick cargo
#

If i write a flask app and i structure it identically to Django's layout is it still a library or is it a framework at that poknt 02Shrug

serene prawn
#

Flask is just a router with extra whistles though

wicked elbow
#

depends on your definitions. django doesnt have a lot built in to work, websockets/json serialization for instance. flask doesnt either. again your comparing apples to oranges. and what you specifically need for your use case

serene prawn
#

compared to say django

#

Also i wouldn't use Flask anymore when there's FastAPI 🙂

quick cargo
#

The only thing django does extra is the orm and the file generation

#

Flask is orientated about being lighter and more module than Django which is fair considering the fact that 70% of everything in django you never use

serene prawn
swift wren
#

true, but using django is faster if you want to build a full webapp if you compared both modules in terms of constructing the app.

quick cargo
#

I mean that depends on what you're doing, if its ecommerce sure

#

But not everything works as well im django's world

serene prawn
#

For api i would choose FastAPI or Django if i feel lazy 😅

swift wren
#

even if you want to make a scalable app, django would be faster

quick cargo
#

Sorta?

swift wren
#

but if you want 100% control over your application then django will fail you

quick cargo
#

Most large companies which hav3 dynamic frontends go with flask for that

#

Unless you're ecommerce

wicked elbow
#

you could for instance run react and query everytime your component loads. you can set context and use the data in other components. react/angular/vue are what you make them. same with django/flask/php/asp

swift wren
#

what is the difference between a eCommerce app and a normal webapp

quick cargo
#

Mostly what they involve using

#

And what django ultimately got popular for

serene prawn
#

Technically you can but it's not applicable for ui elements

quick cargo
#

Yeah and it's one of the main things with front end systems, the virtual doms are very powerful tools

#

But equally alot of websites doesnt really need it over ss other than its very nice to deploy on the edge and not worry about content delivery

wicked elbow
#

you cant server side render react or angular in django or flask. so i dont know why it matters. you'd be running a node.js backend. at least for the SSR im assuming your talking about. to pull data, build the page pass to the front end to rehydrate and deploy.

#

otherwise pass json and filter the data into your components. still not sure what benifit SSR actually would have in the long run

opaque rivet
#

SSR helps with SEO a lot. If you want SSR (or something similar) use next.js, it will improve your SEO as for JS apps it's quite terrible.

serene prawn
wicked elbow
#

if your talking server side redirection your wasting your time with a framework anyways. defeats the whole purpose of react/angular speed of delivery

opaque rivet
#

Django templates doesn't give you the freedom of JS frameworks. You will be hard pressed to not learn a JS framework, most jobs require them.

serene prawn
opaque rivet
#

And tbf react projects should either be done with next.js (react framework) or SSR, create react app has a better competitor giving more SEO and features out of the box.

serene prawn
#

I can't imagine dealing with even small that have any interactive elements without js frameworks

serene prawn
quick cargo
#

Im the same but im on team Vue

opaque rivet
#

Angular 😭 😭

quick cargo
#

As much as i like reacts ease of use styled components kill me

serene prawn
opaque rivet
#

I have angular prejudice I'm sorry

serene prawn
#

I heard that people don't like angular.js though

#

angular is pretty cool imo

quick cargo
#

I like most of angular's stuff but couldn't quite get used to the communication between components

serene prawn
#

Basically can act the same as store in other frameworks

swift wren
#

hey guys, i need to know the difference between express and node. ik it will probs be mad dumb but i just dont see the difference

#

cos both act like "wsgi" if i said that correctly

serene prawn
#

express is a library/framework

#

node is a runtime for js

swift wren
#

yeah but even then, if its a run time, why do people use it along side express

serene prawn
#

So you can run express?...

#

You can't run flask without python 👀

#

Same here

gloomy osprey
swift wren
#

no i saw this tutorial and this guy ran a node.js server and then made a different server in express with differnt ports

#

i didnt understand why he did that

#

even then, react has its own ss

serene prawn
#

You usually serve react via cdn or your node server can serve static files as well

#

Since your app would be just a compiled js file

swift wren
#

but then there is no need for express

serene prawn
#

Maybe he would write an api for that react app using express?

swift wren
#

cos cant raw node.js do the exact same thing that express does

serene prawn
#

It can, but it would be a pain 😉

swift wren
#

really? man there are so many tangents in js.

serene prawn
#

There's no built-in routing or something

coral raven
#

How should I implement flask + react,
Flask runner on port 5000 as api, and react on the frontend making calls to port 5000
Or have both flask and react work on the same port

glacial dew
#

i am making a website in which i have to make some API calls in django, and i make these api calls everytime someone calls my homepage, due to this my home page takes a lot of time load

#

i wanted to establish a mechanism using which these api calls will be made periodically after few hours and my data will get updated

#

this way my home page won't take this much time to load everytime.

#

how to establish this??

Hi, i am learning FastAPI and i found this code exemple on github that i don't understand

class ArticleForResponse(RWSchema, Article):
    tags: List[str] = Field(..., alias="tagList")

what is Field ? what is the 3 dots ?

Hey! I am working on a Django project.The issue I am facing is when I login in one of the non admin page (page which I created through LoginView Class in Django), it also automatically tries to authenticate admin login page and if the user is superuser, the admin page gets logged in even when the superuser does not want to login to the admin page and when a non super user logs in, again it tries to login in the admin page only to not get authorized. How do I not let automatic trial of admin login not happen?

serene prawn
#

For development you can use react server

serene prawn
#

Actually it can be just a function or anything but the main point is that it provides metadata for your model field

ornate burrow
#

where does dash change the tab title to updating? i want to check where it does this so i can add a loading bar on screen

#

and i cant find what im looking for in the documentation

#

or i am misunderstanding the documentation

distant trout
#

someone know if flask has an async extension? need to load in my view first because an API call is taking too long to load

serene prawn
#

@distant trout You can't "put" data in your view if you already sent it to the client

distant trout
serene prawn
#

Not really... If you already sent view to the client then how would you put your data in it? 🤔

distant trout
#

i see sites do the loading spinning thing when a data is taking long to load

serene prawn
#

Consider using cache/javascript requests on frontend

#

Yeah, that's done with js

#

Usually with some js framework

distant trout
#

oh u think i can do it with react

serene prawn
#

angular is my personal favorite though 😉
But it uses typescript so it can be hard to start with it

distant trout
#

ahh lol

#

ok thank u im gonna look into it right now

serene prawn
#

@distant trout Also if you're just starting or your backend is pretty small look into FastAPI

distant trout
serene prawn
#

Well, it has more features

#

Don't know about speed though

distant trout
#

ahh

serene prawn
#

But they're pretty similar and fastapi makes a good use of python type hints

distant trout
#

i see.. okay ill look into fastapi

quick cargo
#

Flask is way faster than people think

#

There generally is alot of miss-conception between asyncio being so much faster vs some other sync framework

serene prawn
#

according to techempower tests it's faster 🤔

quick cargo
#

Ignore tech empower for anything other than the bench marking game of who's framework pipelines better eyerollgopher

serene prawn
#

😅

quick cargo
#

they're very miss leading benchmarks for the real world

serene prawn
quick cargo
#

I mean im not dis-agreeing that FastAPI is awesome for API's

#

its definitely my go to

distant trout
#

apparently fastapi uses ASGI and flask uses WSGI

quick cargo
#

yes and?

serene prawn
#

They're pretty similar, have similar performance, and fastapi has more features than flask

quick cargo
#

they're just different server interfaces for asyncio and not asyncio

serene prawn
#

Is there any reason to use flask anymore? 😅

quick cargo
#

The eco system support, testing support general performance and ease of scalability

#

better stability under high load

distant trout
#

if u had to pick a framework for a simple api, would it be flask or fastapi

quick cargo
#

FastAPI just because speed of setup

distant trout
#

ahh okay

#

fastapi docs are well done

#

also i see it autogenerates documentation

I have a survey for you,

Let's take for example that we want to make 100 Websites (100 domain names, we don't count the sub-domains)

Do you prefer to put 100 domain names in a dedicated server?
or one website per VPS, (total 100 VPS) ?

In my example 1 website is about less than 1000 visitors per month

quick cargo
#

you can pretty easily fit that in a single VPS

native tide
#

Impossible to put everything in a VPS, the hardware will be limited, especially the memory,

I take 1GB or 2GB of memory per VPS, it's enough for a small site

quick cargo
#

I mean we have a 10 core VPS that handles a few hundred thousand unique visitors a month with tens of billions of requests

#

web servers are not really that intensive

i think the scroll into view takes a lil too long to kick in though

its just about on the edge where it looks like it's just scrolling into a blank page rather than scrolling into view

and the best animations are those that dont interfere with use of the site. like a bounce on mouse over, ect. but seriously id say the majority of people when they visit a site, wont care if its animated or not because none of the majorly accessed sites have any animation what-soo-ever

#

Also it works fine on my Windows PC but not a Ubuntu docker container

opaque rivet

yeah that's strange 🤔 , I've never ran into that issue before and I don't see problems with the directory. I did come across this article which looks promising though:

edgy isle
#

I think I know how to fix this

#

The thing that is diffrent for me is on my local computer im trying not to deploy it while on my VPS I am trying to deploy it

#

And on my local computer I am just using Python to run it from the directory where app.py is and on the VPS I am doing its from within main.py's directory with gunicorn

#

I just changed my directory one up and did
gunicorn -b 0.0.0.0:5000 "project.__init__.py"
instead

#

and it works but new problem to solve that I will figure out a fix for

#

Now its saying models doesnt exist

Fixed it

    )
    formOptions = models.CharField(max_length=255, choices=options)
    def whatYouChoose(self):
        if self.test == 'Option1':

        else:
            return models.CharField(max_length=255, help_text='You choose option 2, please write something bellow')

When you choose some option, open some form for you fill what you need

just start one on port 8080 instead

heady iris
#

im really sorry

but how?

django is... python3(py) manage.py 127.0.0.1:8080

theres a similar command for all dev servers

heady iris

wait this is flask tho

#

or is it the same?

wicked elbow
#

default for flask dev is 5000. so you could probably also use port 8000 for it instead

Hello, I'm learning django rest framework and I faced with a problem. In my models I have OneToOne relationship and I'm trying to serialize data, but I have a error:

    name = models.CharField(max_length=255) 
    password = models.CharField(max_length=255)
    birth_date = models.DateField(blank=True, null=True)
    contacts_number = models.PositiveIntegerField(default=0)
    creation_date = models.DateField(auto_now_add=True) 

    def __str__(self):
        return self.name

class Email(models.Model):
    email = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)
    name = models.EmailField()
    is_activated = models.BooleanField(default=False)
    last_modified = models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.name

My serializers:

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ['name', 'password', 'email']
    

class EmailSerializer(serializers.ModelSerializer):
    email_id = UserSerializer(read_only=True)

    class Meta:
        model = Email
        fields = ['email_id', 'name', 'is_activated']

And my view:

class UserRecordView(APIView):
    
    def get(self, request):
        users = Email.objects.all()
        serializer = EmailSerializer(users, many=True)
        return Response(serializer.data)

Can i ask something about bootstrap here?

hexed perch
#

hey i am developing Django project how can i inform fronted(react) after any process is over?

#

like if Django get any input from fronted then it should process the information and when it is over then it should automatically notify the fronted?

tribal pewter
#

you mean sending an input from a form ?

hexed perch
#

no like for example i am giving some input data from front end, it goes to the backed and Django should start processing it and after the process is completed, it should ping the output to front end. like react should not wait until Django completes it work.

tribal pewter
#

Its not really clear what you wanna achieve; you're saying that Django should ping react after the process is completed but not wait for Django to complete

#

how is that

vestal hound
#

server-sent events

hexed perch
#

like i have one algorithm running in the django which take much time to complete and give output. so i want some thing that whenever django complete the executing the algorithm it should notifies the front end like "i have completed the process and this is the output."

vestal hound
#

you can also use WebSockets

#

for this case I would suggest SSE

@hexed perch sounds like a simple API endpoint which you can use DRF for.

hexed perch
#

what is DRF? @opaque rivet

static basin
#

@quiet ridge what a lovely website!!

opaque rivet
#

@hexed perch django rest framework, it allows you to make APIs with django.

hexed perch
#

ya @opaque rivet i am using django rest framework

#

my question was, how can i make reverse api request like server to front end

opaque rivet
#

Oh yeah, that's websockets. Use django channels

#

But you could just use an API view if you want a singular response from the server, don't you think?

# stable hemlock What do you mean by "don't know where you start?"

I'm just unfamiliar with how people start startups, look for funding, etc. I've been really intrigued about it and was wondering if I could turn my original full-stack project into a startup business for funding. I've seen a similar business on ProductHunt with decent success.

I think my next step is to get some market research and maybe solidify whether the business is a good idea for investors or a startup 👍

background-color: var(--dark-blue) fun fact. if you dont know how to do this, you should really learn it. i learned it today and would seriously have saved me a lot of time if i would have known about it a long time ago... anything that uses that var will change when you its value. so no hunting hex codes or rgbs down to change them

yeah, i see it as a few videos here and there on backburner. i've really been getting into this "startup" idea recently. I've only made 2 projects and my most recent one was made as a business. but for the future, all the constraints of profit can go out the window and it can be focused on an ambitious startup plan.

drone startups are really intruiging to me, but they do seem a bit crowded imo

Hello, I have a quick question:
I am trying to get rid of HTML in my request, here is the code:

req = requests.post('https://www.medicine-app.com', data=data)
log.error("debug request")
log.error(req.text)

req_json = req.json()

This is in my terminal:

debug request
{"text_answer":"You can go to your doctor’s or get medical appointment for: <br><br><b>Orthopedic clinic</b> <br>Time: Your first appointment is in July 2021                          <br><br>","response_type":"procedures","data":"[{'name': 'YES', 'value': '1023; 8; 3'}, {'name': 'NO', 'value': 'reset'}]"}

When converting to JSON with req.json() last line I get this error:
JSONDecodeError('Invalid control character at: line 1 column 145 (char 144)')

gritty cloud
#

so apparently you are sending a post request to a full website?

#

@patent ingot

patent ingot
#

That website does not exist, I changed it to some example. Check my terminal..

#

I get that as a response

spring raft
patent ingot
#

I tried with line of code:


    req_json = req.json()
    req_json["text_answer"] = req_json["text_answer"].replace("<b>", "").replace("</b>", "").replace("<br>", " ")
#

But the same error

#

Maybe the problem is when it converts to json.

#

How can I get for req variable to fix the HTML, before I convert to JSON.

Hello everyone, i want get a recommendations for name of my api endpoint
I made an api so that people can get information about the coronavirus vaccination. Before more people use it, I would like to choose good names for the resources, which they think about of the following:

I think in the next

Endpoint for get vaccination history of a country (dates and number of vaccinated that date)
api.covidvaccines.com/api/v1/history-vaccination/countries/:countryId
I think the "/api" is redundant because it is already in it. from the domain "api."

Endpoint for get available countries for make request in previous point
api.covidvaccines.com/api/v1/available_countries

Endpoint for get source of data
api.covidvaccines.com/api/v1/source-data/countries/:countryId

Endpoint for get history of vaccination all country today

@royal ibex just so we're on the same page, do you see how the error message is telling you that the path you passed to it in an empty string?

royal ibex
#

Yes, I'm just unsure of how the admin infrastructure is set up internally. It should just work, Django autogenerates these forms cause of its database functionality

#

I haven't changed the location of the sqlite file so I'm just like. what do

primal grove
royal ibex
#

Nah pycharm did tell me that

primal grove
#

And yet you did not listen 😢

#

anyway, the empty string. Is that what the __str__ method from Ingest_File is returning?

#

like where is this empty string coming from?

primal grove
royal ibex
#

The empty string I believe is supposed to be the path to the object?? Maybe???

#

__str__ is just what that blue text is displaying for each object

primal grove
#

is it supposed to represent a file, and your goal was for the __str__ method to return a path to it?

austere acorn
royal ibex
#

It's supposed to represent an object in a database file stored on the server. I think the problem must lie somewhere in the way my model is set up that's preventing the form from being generated

why does this command open two node shells and doesn't install express ? it worked yesterday

can someone help me with something in django?

toxic flame
#

Sure

proud crow

Hopefully this is the right place to ask this since it's more of a topical question than code help
I'm pretty new to making web apps (not new to python in general), I'm working with Flask to make a web page that will eventually have an AI model that generates replies to user input, think a simple chatbot
I'm trying to get my code pushed up onto a heroku app to test things (was suggested to try Heroku but if there's other services better fit for this lemme know), but I'm having an issue related to the file system there

#

the AI model is ~1.5GB, which is well above the seemingly 500MB limit to heroku's file system for apps, and in general I'm reading that you shouldn't even upload stuff like that to Heroku to begin with

#

so...what's the alternative to doing that? I'm not sure how I'd have everything communicate properly still if the AI model is stored somewhere else separate to the scripts on heroku, let alone knowing where to store it

I'm glossing over a lot of detail here but I can be much more specific about the project if needed, just don't want to flood the channel in case it's not the right place 😅

quick cargo
#

Having a ai on heroku in the first place is a bad idea

#

Unless you're paying for those beefy dynos they have no where near the amount of power to be reasonably useful at hosting that

#

In reality you want a actual vps rather than a free host provider like that

proud crow
#

are there free vps things that would work for this or would I most likely have to pay? this is for a capstone project for my master's degree and I'm on a grant so they'd probably be willing to pay for it if that was needed

#

worst case I don't think it'd be a big issue to just work on it locally and deal with deploying it to an actual service later down the road

hi. What's the simplest way to make a web page that reads a .txt file uploaded by the user, and then gives you back a modified text file? either displaying it in a textbox or something like that or by asking the user to download the modified file

Hello
I need a little help,
Can anyone tell me How can I send data from python file to the HTML page in Flask and vice versa?
So basically my aim is to take input from user in html text box,
send it to a neural network and print the output in the HTML on click of a button

serene prawn
surreal finch
#

Actually I needed both

#

I also found the solution

zealous olive
#

Hello dear awesome developers. I want to Delete, Edit, List, Search and create new data from the database. Then i want to display the output. How can i Connect the database to my HTML Form? If you have any tips, references, videos, anything that can help it will be much appreciated.

serene prawn
surreal finch
# surreal finch I also found the solution

1 - code a simple form to collect user input
2 - code a controller in Flask to receive the information (requests.form[‘name of input text field’])
3 - Code the communication layer with ML
4 - send back the response to the user (render_template)

zealous olive
serene prawn
#

You probably can't do that within single form 😉

zealous olive
#

I do not want to do that within one single form

#

i have made a different page for single steps

#

the main problem is connecting database to the forms

serene prawn
#

Are you using any framework?

#

For backend

zealous olive
#

no sir

#

only pure python

serene prawn
#

Consider using django or fastapi

#

That would be a pain to do in plain python without any frameworks or libraries

marsh canyon
#

or you can also have a database hosted somewhere and connect with it using javascript

serene prawn
marsh canyon
#

but I would say a framework is what is required

serene prawn
#

Just... a bad idea

marsh canyon
#

ye..

#

just hinting at all the possible options

zealous olive
serene prawn
marsh canyon
#

there should be a tutorial on the website

serene prawn
#

There is

#

right on docs page

zealous olive
#

Thank you two. I preciate the immediate help. Have a good one guys! cheers.

marsh canyon
#

before that

#

you should look at how wed dev works

#

I mean, learning about what is frontend and backend

#

cuz django is a backend

serene prawn
#

@marsh canyon Btw are you familiar with django? 🤔

marsh canyon
#

like a brief introduction of web dev

#

yes

zealous olive
serene prawn
#

How should i go about creating services in django compared to say laravel?

marsh canyon
#

I am not sure how laravel works

#

but do you mean REST APIs?

serene prawn
#

No, literally services inside of the app itself

#

Say i want to proxy another api via django

#

So i need say to store that api's session token, make http requests from django itself, etc

#

And i have to get that token first 😅

#

via login/password pair

marsh canyon
#

how are you geting the token?

#

GET request to that api?

serene prawn
#

yep

#

just an http request

#

with login/password attached

marsh canyon
#

so whats the problem after that?

serene prawn
#

I have to store it somehow because it can expire 🤔
Plus i might have a lot of service objects for different purposes

#

And they all have to attach token to the request

marsh canyon
#

you can make a db model for that I guess

#

or store it in cache

#

redis ?

serene prawn
#

I think even file cache will do?

marsh canyon
#

yea I guess, but no a big fan of those

serene prawn
#

I can swap them anyway, right?

#

So no big deal

#

But anyway how do i encapsulate my logic?

#

So i don't do all that stuff in views

marsh canyon
#

you can have tasks

#

periodic tasks

#

or background functions

serene prawn
#

I mean

#

I want to have say PostsService with different methods defined for say storing/retrieving posts from an api

#

So logic stays in one place

#

🤔

#

Just where do i store business logic 😅

marsh canyon
#

what is business logic

serene prawn
#

Any application logic

marsh canyon
#

how is it triggered?

#

when does the application logic need to be called

serene prawn
#

It can be called literally anywhere i guess

#

Most commonly in views 🤔 if i stick to an example with api

quick cargo
#

You're gonna get a bonk if you're storing those passwords in plain text instead of hashing them angryeyes

serene prawn
quick cargo
#

with login/password attached

serene prawn
#

It's an API key/password

#

Not to my api...

quick cargo
#

I would recommend either jwt authorization for this or oauth2

#

Ah

marsh canyon
quick cargo
#

Then ignore me

serene prawn
#

So to the .env they go

marsh canyon
#

if its something that needs to run periodically, then just background tasks, like cornjobs on linux

serene prawn
marsh canyon
#

eh, I am not sure what that means, but if it seems right to you and works, go ahead

serene prawn
#

😅

#

I'm just curious, i have to work at my job with laravel and i hate it )

marsh canyon
#

😬

serene prawn
#

@marsh canyon I guess i can have a class, like ApiServiceBase and make a something like session property that will return a requests.Session object 🤔
with headers attached

#

For that api 🙂

Hello! I am working on a Django/Apache+mod_wsgi website. I was able to create an ssl certificate for https. For now, one virtualhost still works on http (planning to redirect all http requests to https), another one listens port 443 for https requests. Thing is, while the http keeps working even while updating files (e.g. the templates), the https work on an older version (a few days old) and doesn't seem to keep up with the edits... any suggestions?

idle apex
#

i don't know why my form isn't sending data back

elder jackal
idle apex
#

wait let me check devtools

elder jackal
#

you do app.run(debug=True) so you should see some logs in the app

#

your app won't return anything if you request nothing

idle apex
#

checked devtools

elder jackal
#

xD

idle apex
#

i don't think the request went through

elder jackal
#

what did the server say?

idle apex
#

that's just bootstrap stuff

#

yeah

#

csfr token, one 404 and two 200s

#

ok it means your stuff doesn't get rendered

idle apex
#

the form?

elder jackal
#

ye

idle apex
#

how should i get it to render

elder jackal
#

try to debug yourself, do

render_template("index.html", title="Search", form=form)

in a separate file (debug session)

#

check what it is returning

idle apex
#

nothing

#

wait how do i debug a single line

elder jackal
#

you cant

#

do imports and stuff

idle apex
#

what should be in my debug file

#

a route and a function with just the return in it

elder jackal
# 
from flask import render_template
from flask_wtf import FlaskForm
from wtforms import StringField, SubmitField

class SearchForm(FlaskForm):
    term = StringField(label=('Search for:'), validators=[DataRequired()])
    submit = SubmitField(label=('Search'))

form = SearchForm()

variable_to_debug = render_template("index.html", title="Search", form=form)

@elder jackal sorry had to step out for a while

RuntimeError: Working outside of application context.
This typically means that you attempted to use functionality that needed
to interface with the current application object in some way. To solve
this, set up an application context with app.app_context(). See the
documentation for more information.

elder jackal
#

add after import

app = Flask(__name__)
app.app_context().push()

how to use overflow: hidden outside of a body{}?

opaque rivet
#

@native tide ? What do you mean by that

native tide
#

it deosn't seem that i can use overflow:hidden outside out of a body{} like a class div

opaque rivet
#

Not sure what you mean by body{}. All of your HTML goes within your body tags or it will not be in the DOM.

You can apply that CSS rule to a class in CSS like:

.class_of_element {
   overflow: hidden 
}
#

@nimble epoch nope, you send the form data with enctype multipart/form-data and you're able to access the file via request.FILES

native tide
#

what is a class of element?

opaque rivet
native tide
#

oh you mean that, i tried putting overflow: hidden; in the main div it doesn't seem to work

opaque rivet
#

Have you tried to inspect element to ensure that you selected the right div?

native tide
#

i have a scroll-snap so i basically did
body {
overflow-y: hidden;
}
.divcontainer {
scroll-snap-type: y mandatory;
overflow-y: scroll;
display: block;
height: 100vh;
}

i tried wrapping it with a div and replacing the body but it doesn't work

Hello Helper! I am currently having an issue with Django! I have started to make a stock portfolio website and am having trouble with the following:

  • I can't send the data to the views.py file! I am trying to get input from a user in a HTML file and then convert it tl the views.py file.

and in your views you should put

  stock_type = request.POST.get('stock_type') # Just put the name of whatever input you are sending
marble spade
#

@tribal pewter I added the following and got this error:

is this all you have in this views
