or anywhere else

[supple bramble]

in your views.py

[glad patrol]

se this

huh not this 1

i create 2 fields now

height and weight

i dont want that user enter bmi

[supple bramble]

okay

[glad patrol]

bmi auto set when user enter height and weight

how can i achive this

[supple bramble]

wait

[glad patrol]

ok

[supple bramble]

you have added the height and weight in views.py right?

[glad patrol]

right now

this is view.py

    if request.method == 'POST':

        pregnancies = float(request.POST['pregnancies'])
        glucose = float(request.POST['glucose'])
        bloodpressure = float(request.POST['bloodpressure'])
        skinthickness = float(request.POST['skinthickness'])
        bmi = float(request.POST['bmi'])
        insulin = float(request.POST['insulin'])
        pedigree = float(request.POST['pedigree'])
        age = float(request.POST['age'])
        name=str(request.POST['name'])
        date=str(request.POST['date'])
        gender=str(request.POST['gender'])
        mydb = mysql.connector.connect(
            host='localhost',
            user='root',
            password='',
            database='mdss',
            port='3306'
        )
        mycursor = mydb.cursor()
        sql = "INSERT INTO diab (name,gender,date,pregnancies,glucose,bloodpressure,skinthickness,bmi,insulin,pedigree,age) VALUES (%s,%s,%s,%s, %s,%s, %s,%s, %s,%s, %s)"
        val = (name,gender,date,pregnancies,glucose,bloodpressure,skinthickness,bmi,insulin,pedigree,age)
        mycursor.execute(sql, val)

        mydb.commit()```

[supple bramble]

okay so add height and weight like you added other fields, then add
bmi = height*weight

[glad patrol]

then how i set the bmi in html form automatically

[supple bramble]

hmm

placeholder?

[glad patrol]

i can calulate but i dont know how to set it on html page

[supple bramble]

placeholder = f'{bmi}'

where do you wanna show the bmi ?

[glad patrol]

this is bmi in html page

   <div class="col-md-4">
        <div class="form-group">
          <label for="bmi">BMI</label>
          <input
            type="number"
            step=".00001"
            class="form-control"
            id="bmi"
            value="0"
            name="bmi"
          />
        </div>```

right now

like the value set when height and weight multiply

[supple bramble]

hmm

[glad patrol]

like a user restirct he cant add bmi on its own

it auto calculate

[supple bramble]

do something like {bmi} in html

might work

im not sure

[glad patrol]

where i add this

value = {bmi}

[supple bramble]

not sure if it will work, add it in the html page where you want it to show

[glad patrol]

ok i try

can i ping you if i get any error

[supple bramble]

sure

[quartz plinth]

how do u get a hel pchannel

[quartz hedge]

@quartz plinth Could you read #❓｜how-to-get-help?

[vernal furnace]

Guys can I run my django project from my pc and see it from the phone?

I guess no right?

[stray spire]

Yes

You can locally host

[vernal furnace]

How

[stray spire]

steps I don't know offhand, but you can google "locally host django project + your system / other details that are unique to you"

so add in Windows or Linux

or wahtever you're running on

and if you want it accessible outside your local network or not, I'd host locally first and check it out via local IPs

[quartz hedge]

You need to get your IP address, and run it over there instead of localhost. Then only people connected to your WiFi will be able to see it

[stray spire]

then worry about opening it up to the world

Yep, local network vs world wide

I'd recommend getting it up and running locally first, good dry run

might satisfy your current needs

[vernal furnace]

Lemme try mm

[stray spire]

then you can look into an rpi or something else with 24/7 capabilities, or use a free online service

[vernal furnace]

That damn page is not pulling up

https://stackoverflow.com/questions/26311459/locally-hosting-django-project

Can you access it ?

Ok it opened

[quartz hedge]

python manage.py runserver x.x.x.x:8080 Where x.x.x.x you can get from https://whatismyipaddress.com/

[vernal furnace]

ohhh thank you

both

😄

it says getaddrinfo failed

[quartz hedge]

You could try a different port I guess

maybe 3000 or 4200 or something

[vernal furnace]

I think the website gave me the wrong ip

mm

yeah it worked

ipconfig

Thanks so much guys :D!

how can i allow various fonts from discord in my html file

some names are written in a weird way and i get errors

[native tide]

You have two separate views for question and answer. You need both of them to be in the same view if you want to attempt to show both forms in the same template, because having 2 views implies they are both are different URLs

[velvet vale]

@native tide so what do you advise me how to change? An example if you can see it

[native tide]

This is my advising you on how to change it

[velvet vale]

I want to automatically display as many such forms as there are questions and the question will be automatically selected. Do you understand?

@native tide understand?

[mortal mango]

does anyone know why django is telling me disallowed host even though I added my domain to settings.py allowed hosts? ALLOWED_HOSTS = ['207.246.87.164', 'atomlink.tk/', 'www.atomlink.tk/']

[indigo kettle]

idk if this is why but you don't need the /

[mortal mango]

I tried it without it and it still doesn't work for some reason

[indigo kettle]

it is not updating

either you're not pushing it properly, or it's being overwritten somewhere else

[mortal mango]

oh

how do I restart the nginx server?

[swift sky]

systemctl restart nginx

then

systemctl status nginx

@mortal mango

[mortal mango]

ok

how do I update it?

I did systemctl restart nginx but it's still saying disallowed host

[swift sky]

idk friend,

i have my own coding to do at the moment

but those are the commands to restart and check status of nginx server

[mortal mango]

oh ok

[swift sky]

its likely something is happening elsewhere that is restricting access

did you link allowed hosts with available sites

[mortal mango]

@swift sky I fixed it. I did sudo reboot and it worked. I guess the nginx server just needed to be shutdown and started again to update. Do you know a way to update it with a command?

[swift sky]

i usually use systemctl restart nginx

but it seems like you had some permissions and so it wasn't doing it

[mortal mango]

oh ok

[wicked steppe]

ok

I deleted db.sqlite3 from my vps but now when I upload it from my local machine, it automatically deletes. Does anyone know why?

[glossy arrow]

Hey guys, I'm having a problem with Flask and Jinja2, i'm passing a dictionary to the HTML, and looping over the keys with jinja, but the data is being displayed incorrectly inside a modal, and correctly outside a modal

[native tide]

sounds weird, so the modal is just some other html in the same file which you show / don't show with JavaScript?

[glossy arrow]

Well, I have something like the following ```jinja
<table>
<tbody>
{% for i in organizations.keys() %}
<tr>
<h1>{{i}}</h1>
<button class="btn btn-white btn-sm" data-toggle="modal" data-target="#modal">Open</button>
<div id="#modal" class="modal fade" role="dialog">
<div id="modal-content">
<h1>{{i}}</h1>
</div>
</div>
</tr>
{ % endfor %}
</tbody>
</table>

And i'm doing ```py
return render_template("organizations.html", organizations=organizations}

And lets say organizations is the following {"test1": 1, "test2": 0}

[native tide]

{% i for i. -- the first i is correct?

[glossy arrow]

Think so

But for each of the items added to the table, the first h1 outside of the modal is correct, but its wrong inside of the modal

wait

[glossy arrow]

Sorry its supposed to be {% for i in organizations.keys() %} I typed it wrong

But its correct inside my code

[native tide]

ok

[glossy arrow]

But yeah, theres still the problem

[native tide]

lemme see if I can get an example together to try it out .. do you have a repo I could clone?

[glossy arrow]

Uh, not really, its a closed source app

[native tide]

np

[glossy arrow]

So the first h1 is different both times, but the h1 inside the modal is test1 through both of the iterations

[native tide]

it gives out
test1
open
test1
test2
open
test2

for me and I think this is what I would expect.

[native tide]

still a typo in your {% endfor

[glossy arrow]

Oh yeah, sorry

I typed it out by hand

Not sure why its not working for me then

Say I have something like this then ```jinja
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css"/>
</head>
<body>
<table>
<tbody>
{% for i in organizations.keys() %}
<tr>
<h1>Title: {{i}}</h1>
<button data-toggle="modal" data-target="#modal">Open</button>
<div id="#modal" class="modal modal-fade" role="dialog">
<div id="modal-content">
<h2>View Organization</h2>
<h2>Title: {{i}}</h2>
<h2>Address: {{data[i][1]}}</h2>
<!-- And so on for every piece of data, so address, city, state, zip -->
</div>
</div>
</tr>
{{% endfor %}}
</tbody>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
</body>
</html>

[indigo kettle]

@glossy arrow It looks like you're creating a bunch of modals with the same id

you need to create them with unique ids and target the correct one in each iteration

data-target="#modal-{{i}}"
id="#modal-{{i}}"

or something

[glossy arrow]

Ohh ok

Wait, so a different modal for each organization?

Because users can add a new one any time

[glad patrol]

hi

how to set text field based on other 2 text field results

i need to set bmi = weight x height

i write javascript code but its not working

<script type="text/javascript" src="jquery-3.3.1.js"></script>
<script type="text/javascript">
var elem = document.getElementById("height").value;
var elem2 = document.getElementById("weight").value;
var result = parseInt(elem) * parseInt(elem2);
document.getElementById("bmi").value = result.value;
</script>```

when i enter height and weight on html page the bmi value is not set

[gaunt marlin]

you need on change of jquery to trigger it https://www.w3schools.com/jquery/event_change.asp

[glad patrol]

where i put this

after the script

[gaunt marlin]

first you need to import jquery

[glad patrol]

i am new to js and query can u pls show me

[gaunt marlin]

like the link i posted above

$("input").change(function(){
  alert("The text has been changed."); // you functions in this
});

@glad patrol javascript itself doesn't handle much on static website, to make static website interactable you need to learn jquery and ajax

[glad patrol]

shit

[indigo kettle]

Depending on how many organizations you're gonna have you might need to find a better solution

you can make one modal, and alter its contents with javascript

[glad patrol]

how to set input field value on run time base on other two input fields?

[glad patrol]

var heightField = document.getElementById("height");
var weightField = document.getElementById("weight");
var bmiField = document.getElementById("bmi");

function handleHeightOnChange(event) {
  bmiField.value = event.currentTarget.value;
}
function handleWeightOnChange(event) {
  bmiField.value = event.currentTarget.value;
}
heightField.addEventListener('change', handleHeightOnChange);
weightField.addEventListener('change', handleWeightOnChange);```

how to add both height and weight event values ?

I am having a problem with building my Python discord bot on Heroku

this seemed to be the best fitting channel

nvm

[wicked elbow]

sounds dumb, but i know have node.js and django installed on AWS, can i just upload my code from my computer to the server and start the server and it work? or do i have redo all the installs for it to work?

[gaunt marlin]

if your project don't use thid-party packages then sure, else you have to have a requirements.txt file for package management

[wicked elbow]

it doesnt require other 3rd party python packages, but does have 3rd party react packages, but they are all included in my files

[stable kite]

You need all your dependency to be installed on your AWS server. If it is installed than you upload your code & start the server. It will work else you need to install all dependency first

[native tide]

If you don't mind me asking, what AWS service do you use for your django-react projects? I want to start learning how to use AWS

[native tide]

Also are you just using django to serve the index.html and then React handles the rest? Or is it some sort of other setup?

[wicked elbow]

my server is fully up and running now. and yes, django is the server, im still using the developement server so im not gonna link anything to it. wanna run some tests

[wicked elbow]

yea, i got it... took a while.

if i close the ssh will the server continue running

[gaunt marlin]

@wicked elbow when you close the ssh it's also mean the terminal will be closed, look into screen for keeping the terminal up and running

https://linuxize.com/post/how-to-use-linux-screen/

if you using python manage.py runserver

[wicked elbow]

ah ok... im gonna guess thats something that cant be done for free

at least in aws

nah server is still up and running after closing my SSH link

[gaunt marlin]

oh ok

[wicked elbow]

i suppose i could share the public ip though eh? anyone could find it anyways

[native tide]

what is this equivalent in function based views?

[night hawk]

how to change the font in HTML

???

[vestal hound]

font-family style

[night hawk]

in CSS

YA IM RIGHT

[vestal hound]

what?

[night hawk]

this is CSS

NOT html

[vestal hound]

you can use inline styles

which would be in the HTML...

...but nevertheless, I don't really see your point

[night hawk]

give me the example

pls

[vestal hound]

choice of font is not the province of HTML

[night hawk]

give me the font name

of HTML

name a font name

like verdana

[wicked elbow]

css is a child of html... css cant do anyting by itself, but html is plain and ugly without html

[native tide]

https://www.w3schools.com/css/css_howto.asp

man gotta wait up to 48 hours for dns to resolve my domain name

Hello Nut

I can't implement pagination and search function together

Hello. I need help with flask sessions.
Basically, I have my frontend with react and the backend is in flask. My frontend port is 3000 and my backend is 5000 in my localhost machine. when I log in, I want to save some credentials of user in their session like their key. It doesn't matter if they are able to see it or not but I don't want them to change it. I'm already successful in saving their session so basically when they click that button it saves that user session. But when I try to get that session using another api in flask, it is None and its like the data has never saved before. I thought it might be because browsers don't save sessions if they are in seperated ports. I wonder why is this happening and how to fix it? Is it same when I push it into production server with domain?

Is there a way to remove the title "Long URL" in this Django form?

    <form method="POST" action="/create" style="font-family: bebas neue; margin-top: 20%; font-size: 3em; animation: fadeInRight 3s;">
        {% csrf_token %} {{ form.as_p }}
        <center><button type="submit" class="btn link2" style="font-family: bungee; margin-top: 1%; font-size: 0.8em; background-color: white;">Shorten URL</button></center>
    </form>

[native tide]

is long url a field name in your form in the django backend, because you display the form with form.as_p, maybe you can set a display name for this field then.

[mortal mango]

yeah it's a URLField

[native tide]

I have never implemented either, so I wouldn't know

I have an issue...

request.user tries to retrieve a user from the User model. However, I have a custom user model (AbstractUser), how can I change it so that request.user tries to reference it?

[mortal mango]

I just looked through the docs and found verbose_name which sets the title to be something else. I set verbose_name to be an empty string and it makes it blank.

[indigo kettle]

@native tide I think you just need to specify AUTH_USER_MODEL = 'customauth.MyUser' in your settings.py

[native tide]

I have it like that, but request.user still references User

[indigo kettle]

request.user should return an instance of AUTH_USER_MODEL, so i'm not sure

https://docs.djangoproject.com/en/3.1/ref/request-response/#django.http.HttpRequest.user

if they aren't logged in, it will be an anonymous user

@native tide

[dense slate]

@native tide The custom model is in the DB?

That setting mentioned above should "reroute" which user model is used to the appropriate model.

AUTH_USER_MODEL = 'core.CustomUser'

[native tide]

hmm, I'll try test it, what led me to think that was the error was:

[haughty turtle]

Print out request.user

See what you are getting

@native tide

I believe it returns an object.

Your User object.

So like request.user.email will return enail

request.user.username returns the username

request.user returns the User model for the user as an object, can't verify on mobile but I believe this is what it does.

So if your User model doesn't have a suite attribute you will get such error

@native tide

[native tide]

Working on it now

[frosty current]

Sup

[native tide]

Is there any way to access request.user without making an API request

Been having a CORS issue despite following all the correct steps (I think)

[indigo kettle]

you can just visit the api url directly in your browser

[native tide]

Yeah but I've got Token Authentication which requires an Auth header

[rose field]

<center><a class = "download-btn" href = "information.html/files.zip" download="files.zip">bruh</a><center>

it doesnt work

[mortal mango]

how would I add some text inside the text box in django forms?

[haughty turtle]

@native tide that means no one is logged in, do a try-if statement to catch that error or make logging required for that page

@native tide also I do not think you are making a call by getting the object. It's stored in cache on every request.

[native tide]

Yeah I can't log in because when I use postman to try to add my Authorization header (I use token auth) I get a CORS error

[haughty turtle]

Are you passing in your CRSFtoken ?

[native tide]

No... do I need to?

[haughty turtle]

If sending a POST request yes

[native tide]

It's just a GET

[haughty turtle]

Then weird I have gotten such error when trying to login sending a POST requedt

When I got CORS error

What's the error exactly ?

[native tide]

Ok so I will lead you through what I have done this far

1. pip installed djangocorsheaders

2. added it to installed apps

3. added it to middleware

4. added this in settings.py:

ALLOWED_HOSTS = ['*']
CORS_ORIGIN_ALLOW_ALL = True

Then I try to make a GET request in postman

[glossy arrow]

Can I pass jinja2 data in an onclick?

Like ```jinja
<button onclick="myfunction({{whateverdata}})">Click</button>

[native tide]

I'm so lost, are those the steps that you would usually use to modify CORS?

I have had it setup in the past no problem

[haughty turtle]

@glossy arrow should be able to pass in whatever you want as a parameter

[glossy arrow]

Yeah, but it doesn't seem to work

[haughty turtle]

Because it's inside of a ""

@glossy arrow

[glossy arrow]

@haughty turtle No, its sort of working

So Im doing something like this ```jinja
{{% for i in organizations.keys() %}}
...
<button onclick="myfunction({{i}}, {{data}})">Click</button>
...
{{% endfor %}}

So im looping over a dictionaries keys

and lets say i is test

and data is a dict

Its saying that test is not defined

So its loading in the value for i

But saying its undefined

[haughty turtle]

https://stackoverflow.com/questions/19399610/passing-a-parameter-to-function-with-single-quote

@glossy arrow it's because your passing a var inside of a string as said. Take a look at the link

[glossy arrow]

Cool, i'll look at that, thanks :D

Hm, that doesn't seem to solve the problem

Wait

yeah it doesn't solve the problem

Its not showing anything about jinja values

[native tide]

I did successfully include Jinja2 in JavaScript like below, so maybe safe helps / maybe there is a way to rewrite your code?
<script> {% if mytable %} var table_data = {{ mytable|safe }}; {% else %} var table_data = null; {% endif %} // table_data.data = table_data.data.slice(0,5); // DEV config sub array </script>

[glossy arrow]

Thanks :D I can't figure out why its not working, but I found somewhat of a workaround

[haughty turtle]

Did you try the solution?

[glossy arrow]

Didn''t work

[native tide]

Does anyone know why DRF is giving me an AnonymousUser forrequest.user?

So anyways I don't think DRF catches on to my AUTH_USER_MODEL

Do I need to write some sort of custom middleware so that request.user references my custom usermodel, and not that of the default django user model?

[dense slate]

Shouldn't have to.

https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html

That is what I used to do it my first time and it shouldn't be a complicated process.

Last option is what you want.

[uneven wren]

Hello, i need to persist session after logout to load my cart on next login. Is it alright to overwrite logout function to do not flush session ? Thanks

[native tide]

So, when you extended User model with AbstractUser, did request.user return your customAUTH_USER_MODEL or the User model?

Because from what I see request.user is set to return an instance of the User model...

I'm pretty sure custom authentication / middleware is needed here...

[spiral needle]

Why does no data get sent when I include POST data directly in the urllib.request.Request object, but rather I have to pass the kwarg when calling urllib.request.urlopen?

e.g. : urllib.request.urlopen(urllib.request.Request(url, data=DATA), method="POST") doesn't work, while urllib.request.urlopen(urllib.request.Request(url, ...), data=DATA, method="POST") does

Both the Request class's initializer and the urlopen function accept the data kwarg yet only the former appends data to the body

sorry if this isn't the right channel to ask

[native tide]

Can someone explain why this header:
Authorization: Token cb5837c90e8f8c352a370798e058e42d5913eeb4

returns None from this code:

    def authenticate(self, request):
        auth = get_authorization_header(request).split()

        if not auth or auth[0].lower() != self.keyword.lower().encode():
            return None

[vestal hound]

is that the whole function?

[quick cargo]

you sure its not asking for Bearer or smth

assuming that get_authorization_header(request).split() is doing anything extra

[native tide]

Well, I'm using DRF's TokenAuthentication and when I make requests it's returning None. When I edit what the code returns, the output is different.

[vestal hound]

is that a yes?

[native tide]

That's a no

But it's narrowed down

[native tide]

Confident that it should be Token

not too sure on what this does though

self.keyword.lower().encode():

[vestal hound]

my guess would be

verifying that the header starts with the given keyword

[native tide]

self.keyword.lower() is token

[vestal hound]

which, in this case, is expected to be Token

[native tide]

yeah, what's with the .encode() on the end?

[vestal hound]

presumably

since the header comes from a HTTP request

it's a bytestring

and self.keyword is a string

so to compare the two you need to either decode one or encode the other

[native tide]

    def authenticate(self, request):
        auth = get_authorization_header(request).split()

        if not auth:
            return None

This still returns None

Maybe I'm looking at the wrong thing...

[quick cargo]

print(auth)

[native tide]

empty list

[]

[quick cargo]

okay

what does get_authorization_header(request) return

can you print that?

[vestal hound]

p sure it's empty

are you sure your request contains the right header?

[quick cargo]

and maybe also print(request.headers)

i recon its gonna be a headers property or smth, i dont do much django but its pretty much the same across all systems

[edgy isle]

How do you get all the chosen options with select2?

[native tide]

This is the right header according to the docs:
Authorization: Token cb5837c90e8f8c352a370798e058e42d5913eeb4

However I am using postman and they may be adding something which I don't see, I can try from my react frontend.

The issue I am originally having is that request.user is returning AnonymousUser instead of my AUTH_USER_MODEL specified in settings.py

[native tide]

{'Content-Length': '', 'Content-Type': 'text/plain', 'Host': '127.0.0.1:8000', 'User-Agent': 'PostmanRuntime/7.26.10', 'Accept': '*/*', 'Accept-Language': 'en-GB,en;q=0.5', 'Accept-Encoding': 'gzip, deflate', 'Authorization': '', 'Origin': 'https://web.postman.co', 'Connection': 'keep-alive'}

Interesting

So the Authorization header is empty

[quick cargo]

would appear so

[vestal hound]

yeah, this was my guess

problem solved

[native tide]

I'm specifying a value for the header in postman 🤷‍♂️

I'll try this from my frontend and see if it differs

OMG

Postman has 3 columns, "key", "value", and "description", I mistook the "description" column for "value" as it was hidden.

Thank you so much @quick cargo @vestal hound I was stuck on that all day

        db = sqlite3.connect("textPosts.db")
        c = db.cursor()

        sql = ("SELECT textContent FROM textPosts WHERE username=?")
        val = ([user])
        
        c.execute(sql, val)
        result = c.fetchall()

        for text in result:
            print(text)
            
        c.close()
        db.close()

        return render_template("view-text-uploads.html", result=text)```

```html
            {% for text in result %}
            <p>{{ text }}</p>
            {% endfor %}

only returns last item of list

what it returns

what it should return

ping if responding

[indigo kettle]

you wrote result=text

@jolly pilot

maybe you want result=result?

[jolly pilot]

for some reason there are 2 tuples

so i had to do that

this is with result

[indigo kettle]

I guess you're retrieving all the columns

but there is only one

what happens if you do result=result

[jolly pilot]

well the image

[jolly pilot]

.

[indigo kettle]

oh

then can you do {{text[0]}}

[jolly pilot]

i want all the items

to be shown

[indigo kettle]

it will

[jolly pilot]

nope

[indigo kettle]

wdym

if you do result=result and do your for loop but use {{text[0]}} I think that should work

[jolly pilot]

it doesnt

[indigo kettle]

ok so what's happening

[jolly pilot]

so you mean

return render_template("view-text-uploads.html", result=result)

            {% for text in result %}
            <p style="color: white;">{{ text }}</p>
            {% endfor %}```

right?

[indigo kettle]

text[0]

then yes

[indigo kettle]

mm, you might be consuming the data with your forloop inside the view

[jolly pilot]

what

[indigo kettle]

result = [x for x in c.fetchall()]
maybe try this instead of
result = c.fetchall()

[jolly pilot]

do i do result=text or result=result

[indigo kettle]

result = result

if you do result = text, it will only be the last one

[jolly pilot]

nope

[indigo kettle]

are you doing text[0]?

[edgy isle]

How do you get all the chosen options with select2?
Ive tried getlist but it just does the first selected object

actually, nevermind, I just figured out my actual problem and the solution to it as I typed the question

[glad patrol]

hi

i am creating some basic app hospital system , i need some help

how to generate report in django , i have some variable's holding information like name , bmi , age etc i want to display in some report template .

[ashen sparrow]

@glad patrol write model_name.objects.all() to get all objects of your models.
Pass the resulting query set to your templates and then in your html you can simply iterate over it query set using jinja

[glad patrol]

@ashen sparrow i am using sql database direct not model

[ashen sparrow]

Are you using SQLaclhemy?

[glad patrol]

no sql database

phpmyadmin

[gaunt marlin]

phpmyadmin is a database GUI, not the database

[glad patrol]

sql database

[gaunt marlin]

he asking what ORM are you using

[ashen sparrow]

@glad patrol whatever you do, you need to perform a query on your database similar to
SELECT * FROM REPORT_TABLE

[glad patrol]

i done the query

i get the results

i just want to display it on page

[ashen sparrow]

Now populate result in a list

[glad patrol]

like prescription reeport

[ashen sparrow]

And pass the list to your templates

[glad patrol]

The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol.

i am getting this error even i import utf-8 in html page

[ashen sparrow]

Where did you import it and how are you using it?

[glad patrol]

i import in <head> tag

in first line

[ashen sparrow]

Before you pass your results to the template, try encoding it into utf8

[glad patrol]

nono

i am not doing reporting part right now

yesterday app working fine

[gaunt marlin]

set this in your html meta tag

<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<meta content="utf-8" http-equiv="encoding">

[glad patrol]

now its throwing this error

i set this

<!DOCTYPE html>
<html lang="en">
  <head>
<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<meta content="utf-8" http-equiv="encoding">

    <!-- Required meta tags -->
    <meta
      name="viewport"
      content="width=device-width, initial-scale=1, shrink-to-fit=no"
    />```

[gaunt marlin]

better to show the image of the error on the page

[glad patrol]

ok w8

[gaunt marlin]

this happen after you submit the form?

[glad patrol]

when i open https://172.17.85.70:8000 then i selete diabtese form then this appear

[gaunt marlin]

can you show your form template?

[glad patrol]

yes

[gaunt marlin]

maybe it's missing in some child template or parent template

[glad patrol]

i show u both base.html

and diabetes.html

[gaunt marlin]

even better, right click -> show page source

so we can know if it has

<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<meta content="utf-8" http-equiv="encoding">

[glad patrol]

from browser ?

[gaunt marlin]

yeah

[glad patrol]

it only show this

[gaunt marlin]

ok then post the html of base.html?

[glad patrol]

ok

[lavish prism]

Hey @glad patrol!

Uh-oh! It looks like your message got zapped by our spam filter. We currently don't allow .txt attachments, so here are some tips to help you travel safely:

• If you attempted to send a message longer than 2000 characters, try shortening your message to fit within the character limit or use a pasting service (see below)

• If you tried to show someone your code, you can use codeblocks
(run !code-blocks in #bot-commands for more information) or use a pasting service like:

https://paste.pythondiscord.com

[glad patrol]

https://paste.pythondiscord.com/jiraqazoze.xml

i guess its not using meta header

[gaunt marlin]

yeah that the problem

[glad patrol]

should i need to run migration ?

or reload project?

yesterday this happen i add meta and its work now its not working

[gaunt marlin]

ok now show me the diabetes.html?

[glad patrol]

ok

https://paste.pythondiscord.com/xucidavoda.js

[gaunt marlin]

@glad patrol can you add space to these template tag?

{%extends 'base.html'%} {%block content%}

[glad patrol]

ok i add w8

[gaunt marlin]

like so

{% extends 'base.html' %} {% block content %}

[glad patrol]

w8

same error

if i reload the project

its works fine

if i add something then run it give me error

[gaunt marlin]

reload the project?

like restart the django server?

[glad patrol]

i have rar file backup

if i use that rar file backup its work

even the same meta tag are inserted

see now i unzip my backup and its working fine

if i add another html file in templates it start giving the errors

[gaunt marlin]

that pretty strange, what is your project structure like?

[glad patrol]

means?

[zinc hill]

what type of error?

[gaunt marlin]

you got a 500 server error @glad patrol try to print out what caused the error and put debug=True

i don't think the error related to the utf8

but the logic in the view itself

[glad patrol]

anyway i get ridoff later

can u pls tell 1 more thing

[gaunt marlin]

@glad patrol yeah put DEBUG=True in settings.py

so the page can show the real error

[glad patrol]

ok

  pregnancies = float(request.POST['pregnancies'])
        glucose = float(request.POST['glucose'])
        bloodpressure = float(request.POST['bloodpressure'])
        skinthickness = float(request.POST['skinthickness'])
        bmi = float(request.POST['bmi'])
        insulin = float(request.POST['insulin'])
        pedigree = float(request.POST['pedigree'])
        age = float(request.POST['age'])
        name=str(request.POST['name'])
        date=str(request.POST['date'])
        gender=str(request.POST['gender'])
        bloodgroup=str(request.POST['bloodgroup'])
        mrn = int(request.POST['mrn'])```

i have this information which i send into database

how to generate report from this

[gaunt marlin]

yeah but can you reload that page with DEBUG=True?

[glad patrol]

1 mint

huh

i fix this

the error is i define index.html which is not even exsist

lol

i remove from diabetes.html

and its working

@gaunt marlin

i have report.html page

i add <a href="{% url 'report' %}">Home</a> in my diabetest.html page

when i click on home link it wont open the report page

thats why 500 erro occurs

`django.urls.exceptions.NoReverseMatch

django.urls.exceptions.NoReverseMatch: Reverse for 'report' not found. 'report' is not a valid view function or pattern name.
`

[analog arch]

Use {% url 'app_name:report' %} where app_name is the name of the app that contains your report view function

[gaunt marlin]

@glad patrol you can set the name of your url like so

from django.urls import include, path

urlpatterns = [
    path('index/', views.index, name='main-view'),
    path('bio/<username>/', views.bio, name='bio'),
    path('articles/<slug:title>/', views.article, name='article-detail'),
    path('articles/<slug:title>/<int:section>/', views.section, name='article-section'),
    path('weblog/', include('blog.urls')),
    ...
]

if 2 or more apps have urls with same name then you need to call app_name:url_name instead

[glad patrol]

i can import app with in app ?

and call 1 app url from another app?

[gaunt marlin]

yes

@glad patrol https://docs.djangoproject.com/en/3.1/topics/http/urls/#naming-url-patterns

[glad patrol]

so i need to run two manage.py for both app ?

or they both run at once with 1 manage.py?

[gaunt marlin]

manage.py runserver will run the entire project

project have many apps

so it will run all the apps

[glad patrol]

on the same ip and port ?

[haughty turtle]

yes

[pallid fable]

it's a long shot, but any chance I can get some help writing some REST API in YAML?

for a language that claims to be human readable, it sure reads like some fat nonsense

[plain zealot]

Hey so I keep on getting blocked by Cors policy when I make a fetch request

Anyone know what can I do to fix it?

[vestal hound]

Hey so I keep on getting blocked by Cors policy when I make a fetch request
@plain zealot your backend needs to serve the appropriate headers

it's a long shot, but any chance I can get some help writing some REST API in YAML?
@pallid fable you mean parsing YAML in your API?

or rendering and returning a YAML response?

[pallid fable]

I literally have to send a REST request using YAML

[vestal hound]

okay so like sending YAML in the request body?

[pallid fable]

I wish

I know this sounds like something YAML doesn’t do

[vestal hound]

...I don’t really understand

[pallid fable]

But I actually have to format and send a GET request to an IPAM server, with the intention of receiving the next free IP address in a subnet

The code that sends the GET request is supposed to be written in YAML

[plain zealot]

Found another way to fix

But thanks

[pallid fable]

That makes two of us, but my boss is convinced this should be possible

[vestal hound]

The code that sends the GET request is supposed to be written in YAML
@pallid fable ...wtf?

[pallid fable]

Yup

[vestal hound]

Found another way to fix
@plain zealot okay, hope it’s secure

[pallid fable]

To be fair, I’ve figured out how to do something sorta similar using the URI module

If it helps, this is being hosted by Ansible

Well, the code is being run from Ansible

[vestal hound]

...YAML can’t even be run...?

[pallid fable]

I think Ansible makes it work somehow

I got introduced to YAML and Ansible like a week ago. I’m a newish hire, and we’re in the process of moving our service onto Ansible. I’m translating workflows into Ansible/YAML

[vestal hound]

...it’s not an executable language

[pallid fable]

The old code that did this task was written in JavaScript which makes so much more sense

[pallid fable]

This thought has gone through my head so many times over the last week you have no idea

[vestal hound]

I have no idea either

🥴

sorry

[pallid fable]

best I can explain it is that Ansible interprets YAML as an executable language

here's an example from the URI module documentation page

- name: Login to a form based webpage, then use the returned cookie to access the app in later tasks
  uri:
    url: https://your.form.based.auth.example.com/index.php
    method: POST
    body_format: form-urlencoded
    body:
      name: your_username
      password: your_password
      enter: Sign in
    status_code: 302
  register: login```

I mean, this is definitely written in YAML. But it also looks a lot like it's meant to be executed

[gaunt marlin]

Is there a reason your boss chose YAML to do request of all the things that existed out there?

[pallid fable]

I think they like that Ansible Tower (service running the workflows) has a much more modern interface than the old service we used for workflows

so the fact that all this shit now needs to be done in YAML is more of a side-effect

but I also arrived after this transition began so idk

I'm just a sad new college grad I wasn't ready for the level of bullshit that makes up YAML

"human friendly" my ass

[gaunt marlin]

the only thing i feels comfortable for YAML to run is writing test flow 🤣

but everyone going for that automation flow i guess

¯_(ツ)_/¯

[pallid fable]

just looked into it a bit more closely. Ansible uses an 'easy and descriptive language based on YAML and Jinja templates"

[pallid fable]

ah yes, that reminded me why we switched to Ansible. Something about how updates and workflows can be automated to run locally on the individual machines of our clients instead of pushed from outside

[pallid fable]

in case you're not following this anymore, I figured out the disconnect: Ansible doesn't use YAML, it uses its own language based on YAML and Jinja

so it looks like YAML but it runs

because someone made the conscious decision that YAML would totally be a good executable language, somehow

[gaunt marlin]

i think they just like syntax of YAML without all the curly brackets

[pallid fable]

bahahaha they don't use the curly brackets? All my coworkers have been using them, can't wait to tell them why their code isn't running for shit

[honest dock]

<div class="quantity">
  <input type="number" class="qty-text" id="qty" step="1" min="1" max="12" name="quantity" value="1">
</div>
<a href="{% url 'add_to_cart' slug=quantity.value %}" type="submit" name="addtocart" value="5" class="cart-submit">Add to cart</a>

Django question to you guys, how do I pass to the slug the input value?

[native tide]

does "{{quantity.value}}" work?

[honest dock]

I will give it a try but I doubt since it's not a variable? Give me a sec

[native tide]

Oh, my bad

I thought you were passing it in context

[honest dock]

Uh uh 😦

[native tide]

That being said, is there a possibility you can pass the slug through context to your template, then access it within the value?

[honest dock]

I don't understand ^^

I'm just trying to add a product to the cart, and i need the quantity to be passed in the url as well (having 2 slugs/parameters is another problem i'll be checking later on)

[native tide]

So in your view you will set the slug

def view(request):
  slug = "something"
  render_template(request, template, {"slug": slug})

[honest dock]

Okay and so the slug will be changed in the input?

[native tide]

I guess so, so you will pass your slug through the context and within your template you can access it with:
{{slug}}

[honest dock]

yup yup

and the url 'add_to_cart' can have multiple slugs right?

[native tide]

The URL itself yes

That example was for django

For flask it's basically identical

[honest dock]

I see

so it's something like:

path('addToCart/<slug:slug>/<amount:amount>', .....

[native tide]

Yes

And I believe you can access those parameters as so:

def view(request, slug, amount):
  ...

[honest dock]

Alright thank you man!

[native tide]

<amount: amount> amount is not a valid type, if you want it to be an int it should be <int: amount> or if not an int, just leave it as <amount>

what is he doing here?

[gaunt marlin]

turn list of dictionaries that contains keys and values into json data for example it converted into this:

nope

Why doesn't Flask accept ../ as a path:variable in route decorator? e.g. @app.route("/test/<path:var>")

[native tide]

when I try to pass list as context and set that list as an array var in template and console log that, it shows some unusual characters like this:

['University of Oxford', 'Stanford University', 'Harvard University']

how can I solve?

[sonic ferry]

Looks like the single quote is being converted into the hex value 27

[native tide]

what should I do?

[haughty turtle]

that has to do with safe

enable safe

on the list call

[native tide]

how?

[haughty turtle]

https://docs.djangoproject.com/en/3.1/ref/templates/builtins/#std:templatefilter-safe

[native tide]

where exactly it is?

[haughty turtle]

safe¶
Marks a string as not requiring further HTML escaping prior to output. When autoescaping is off, this filter has no effect.

Note

If you are chaining filters, a filter applied after safe can make the contents unsafe again. For example, the following code prints the variable as is, unescaped:

{{ var|safe|escape }}

How can I serialize a queryset into JSON without it being a list?

[haughty turtle]

Loop through it as so

for i in all_projects:
    project_dict[i.pk] = { "Title": i.Title,  "Description": i.Description, "PhotoName": i.PhotoName, "Tags": i.Tags, "GithubLink": i.GithubLink}
return JsonResponse({'details': project_dict})```

this is what I use

[native tide]

Thanks, I tried to avoid specifying the fields directly incase the model changes, I guess I can loop through the fields and do the same.

[haughty turtle]

I mean I think what I am doing is mapping

[haughty turtle]

What if you do .values() and get a list of dicts and then do a dict comprehension?

@native tide is {{ obj.long_url }} jinja2?

@native tide I'm getting redirect() unexpected keyword argument 'url'. Do you know why this is happening?

actually nvm

[indigo kettle]

that function is also recursive, I think unintentionally? You may want to rename it

def page_redirect(request, url):
    if request.method == 'POST':
        form = CreateNewShortURL(request.POST)
        if form.is_valid():
            original_website = form.cleaned_data['long_url']
            return HttpResponseRedirect(original_website)
````ValueError: The view urlshort.views.page_redirect didn't return an HttpResponse object. It returned None instead.` Does anyone know why this is happening?

[indigo kettle]

if request.method is not 'POST' then you will return None

if form is invalid, you will return None

[mortal mango]

so how do I make it return a post?

[indigo kettle]

make it return a post?

I'm not sure what you mean

[mortal mango]

I mean like how do I make it not return None

sorry

[indigo kettle]

how do you make a function not return None

you have to return something right

there are two places where your function can exit without returning

you can have a catchall return at the end

with some sort of error

like a Http400 response

return HttpResponseBadRequest('invalid request')

or something

[mortal mango]

oh ok

same error

def page_redirect(request, url):
    if request.method == 'POST':

        form = CreateNewShortURL(request.POST)

        if form.is_valid():

            original_website = form.cleaned_data['long_url']

            return HttpResponseBadRequest('invalid request')

[indigo kettle]

the return you had before was fine

but look

you have two if statements right

[mortal mango]

yeah

[indigo kettle]

if either of those are false, then your function will return None

because there is no return after those if statements

[mortal mango]

oh ok

[indigo kettle]

does that make sense?

[mortal mango]

yeah

I put a couple print statements

it's if request.method == 'POST': that's returning False

class CreateNewShortURL(forms.ModelForm):
    class Meta:
        model=ShortURL
        fields = {'long_url'}

        widgets = {
            'long_url': forms.URLInput(attrs={'class': 'form-control'})
        }
``` @indigo kettle this is my form. I want to get `long_url` and put it in my `HttpResponseRedirect()`. How would I do that?

[indigo kettle]

form.cleaned_data['long_url'] did that not work

[mortal mango]

I did

def page_redirect(request, url):
    if request.method == 'GET':
        return HttpResponseRedirect(f'/')
```And it worked

but when i did

def page_redirect(request, url):
    if request.method == 'GET':
        form = CreateNewShortURL(request.GET)
        if form.is_valid():
            original_website = form.cleaned_data['long_url']
            return HttpResponseRedirect(f'{original_website}')
```it didn't and gave me the same error as last time

@indigo kettle

[indigo kettle]

?

you're checking if the request is a GET but then putting request.post into your form

the post. will be empty

your form will probably be invalid

and then your function will return None

[mortal mango]

oh, I meant request.GET

but even if I do that, it still gives the same error

@indigo kettle

[native tide]

you can use a serializer, and then pass it to your template

[cold portal]

I have this issue with a form. It posts but the post code isn’t hit. Instead the get code is hit. I worked around it but never did get it fixed.

The form works fine though... mystery to me

[vestal hound]

so is the actual request GET or POST?

like based on logs

[cold portal]

I see both when I hit the submit button, but the get is what actually hits with regard to console output

[vestal hound]

hm.

that's not right

also that could lead to production bugs

because GET can be cached

[cold portal]

I am using an UpdateView. The form is an edit profile screen that displays the user’s details and lets them edit the fields

I hope that’s not going to be a problem when it’s in production

[vestal hound]

so vanilla Django?

[vestal hound]

it could be

do you know the difference between GET and POST?

[cold portal]

Yeah

And he’s

Yes*

[vestal hound]

like from a spec perspective

[vestal hound]

okay then you should know why it could be a problem...?

[clever hedge]

What's the problem?

[cold portal]

I guess from a behind the scenes caching I don’t know where there would be a problem. Not sure even where the caching would occur

Nothing as far as I can tell. I was commenting on someone else having an issue with form submission not hitting an if block checking if the request if a post

[vestal hound]

caching happens on the server side

like the actual webserver

but browsers can also cache responses to GET requests

[cold portal]

So looking at potential memory problem

[vestal hound]

no.

okay example

a static image is retrieved with a GET

[cold portal]

Yeah

[vestal hound]

and the next time you browse the page (if the site is set up a certain way), you won't need to retrieve it again

because your browser has cached it

if the update request is submitted with a GET

the browser could cache that too

so your request never gets sent to the server

but you get back a "success" response

also, separately, GET requests should be idempotent, but updating is also an idempotent operation so that's not a problem here

[cold portal]

Thanks for that info. I have a lot more reading to do. There is a post recorded in the console it would seem it is posting. On form submission the user is sent back to the same page so I expect a get. Hopefully there’s nothing to worry about, but it’s something to read up on to be sure.

[edgy isle]

Why is my stylesheets being replaced by the error page template?

oh nvm

That was wierd

uhm wtf

That was so wierd

I forgot to add the {{ url_for('static', filename='

[native tide]

I have a field named suite within my model:

class Customer(AbstractUser):
    suite = models.OneToOneField(Suite, on_delete=models.CASCADE, null=True)
    premium = models.BooleanField(null=False, default=False)

Why is it being named suite_id within my DB? Can I rename it?

[mortal mango]

@indigo kettle the first if statement is working now but the second one isn't. For some reason, the form is not valid. Do you know why this is happening?

[indigo kettle]

I don't

I would write some print statements to see what is wrong

you can print form.errors or something

and also print request.GET and see if you're getting the correct params

[mortal mango]

<ul class="errorlist"><li>long_url<ul class="errorlist"><li>This field is required.</li></ul></li></ul> this is what form.errors returns

[native tide]

your form cannot be validated because some fields are empty (when they are required)

try use redirect()

[mortal mango]

oh ok

[mortal mango]

so replace HttpResponseRedirect with redirect?

[native tide]

I guess so, it may help (but it looks like the issue lies with the form)

[heady stream]

hey guys, idk if someone can help me with this but I am really struggling with flask progress bars!
I have searched everywhere for this, found a some examples online but they were only for file uploads which is not what I want.
I am failing to understand how to bind the python to the js and html!
I am working with someone on a neuron tracing project and they need some help with frontend.
The web portal is pretty simple and it just includes inputting your file tracing path (*.txt) and image path (**.tif) and then wait until another tab opens up which reveals a neurologlancer with a 3d view of your neuron (pretty nice!)
Now, my issue with this is the following:
the function that basically takes the whole time to load is in a different file than app.py and it includes the following code:

def func_that_takes_the_whole_time():
  # code here 
  with mp.Pool(mp.cpu_count() * 2) as p:
          # p.map(p_matting, range(0, len(gs_dict)))
          with tqdm(total=len(gs_dict)) as pbar:
              for i, _ in enumerate(p.imap_unordered(p_matting, range(0, len(gs_dict)))):
                  pbar.update()
  # more code here
  return something here

this is a progress bar that shows in the terminal
how can i get this to output in the frontend for the user to see, because the neuroglancer tab takes a bit of time to launch!
I am still a beginner to flask and am not even studying to become a developer, so it would mean a lot if somebody can help, been struggling with this for days!

Sorry for throwing this at you, but the result of tqdm only showing in terminal, want to find a way to output to user so they don't think they entered wrong input after clicking run!
Thanks a ton to whomever helps with this!

[proper hinge]

I don't think tqdm is appropriate for use with the web

I think it's relatively simple to render the progress bar on the web page

The tricky part is how to update the bar with the current progress

Since the server has to somehow relay that info to the client

I don't have an exact picture of how to architecture this, but I imagine you could accomplish this with a websocket

There's also eventsource, but that may be trickier since it's uni-directional.

I'd say to look into using a websocket

Hello everyone. im deploying a django project as a test on heroku wanted to know if i can use my local static file on heroku?

[quick cargo]

As much as that seems like a pretty good offer, it is against the Rules here to have the ads sorry

[quick cargo]

You sure its not escaping and / or overriding tailwind's css

[nimble epoch]

try class="m-1"

[nimble epoch]

anyone?

[cloud path]

mmm

other styles are the ones of css i think

[gaunt marlin]

@nimble epoch django staticfile deploy on heroku you can look over the following document https://devcenter.heroku.com/articles/django-assets

[cloud path]

i don't think it is escaping them probably it's just adding new ones too

now imma try m-1 thanks guys

[nimble epoch]

ok so if yaself know it doesnt support it to use static files localy then i gotta use something called whitenoise. right?

[gaunt marlin]

yeah

better to look over it because it's official heroku documents

[nimble epoch]

ok thanks i am

and of course im looking.... do you yourself have any idea about it?

[gaunt marlin]

i never deploy static on heroku before, i usually use nginx on VPS to serve my staticfile folder

[nimble epoch]

soo can i use my local folder in nginx

?

[gaunt marlin]

like you hosting the staticfile folder?

[nimble epoch]

yeap

[gaunt marlin]

don't know if that a good choice, why not use an amazon s3 server instead?

[nimble epoch]

i dont want to pay money lol

[gaunt marlin]

i mean heroku staticfile deploy is free

[nimble epoch]

or any free web services?

[gaunt marlin]

you can deploy django on heroku without costing money

[nimble epoch]

yeah im reading the docs youve just sent so that ill do that

@gaunt marlin just read this => ''Your application will now serve static assets directly from Gunicorn in production''. should i use something in Procfile to access static file or just like dev, i gotta add something like {% static ..... %}?

or im wrong?

oh ok i got it.thanks

[gaunt marlin]

@nimble epoch do you want to run django on heroku with production or development environment?

[nimble epoch]

production

how?

[gaunt marlin]

oh i'm just asking, because you don't have to handle staticfile on heroku if django is in development environment

[nimble epoch]

yeah

its production that its got so complicated lol

guy who here is good at react?

Hey everyone. Have questions about Django.

For example if I have article model and want to steam it into my template i usually do it with {{ article.content }}
but if i want stream one content into few separate <div> first half of text from article.content </div> and <div> second part of text from article.content</div>

How can i do that?

[native tide]

maybe you should add two model functions to your model, one gives back the first part, one the second, those model functions you can call similarily to fields in a template.

so I am following the following code to create a progress bar (loading bar): https://github.com/deshraj/flask-SocketIO-Progressbar
In my web portal as I click Run button to perform my web's functionality, my web starts loading forever and nothing new happens as I am supposed to enter a new tab!
As I enter: http://127.0.0.1:5001/socket.io/ I get the following message:
"The client is using an unsupported version of the Socket.IO or Engine.IO protocols"
I am running:
python-engineio 4.0.0
python-socketio 5.0.4
Flask-SocketIO 5.0.1
and I have changed the javascript socket.io version in the github from 0.9.16 to 3.13.2
According to flask documentation, these should be compatible!

I want to to enable password reset/forgot password with django rest-auth but its a little sparse for help in the rest-auth docs. What's the flow for building a password reset? It seems like a POST req (/rest-auth/password/reset/) should be made with the email address. And then some how and an email needs to be sent to the user. And then from there another POST req (/rest-auth/password/reset/confirm/) should be made but there's supposed to be a UID and token that goes with the POST req but I have no idea where this comes from or how to send emails out with it

Which is better to use? Django rest framework or django as full stack

[native tide]

Hi

Anyone familiar with any decent shared hosting for python web apps?

Heroku, pythonAnywhere and linode are expensive for me

[buoyant shuttle]

heroku has a free option

you can use that

I use a web hosting service, called alawaysdata.net. its a french web hosting service they have a free plan

[buoyant shuttle]

it depends, if you want to deal with other APIS and stuff, maybe django rest framework

[finite brook]

it depends, if you want to deal with other APIS and stuff, maybe django rest framework

I am using Mongo Atlas (free tier) on a Django website. Everything's running fine from my local, but on server all my queries are running slow. For instance an update_one() query that takes around 0.5 seconds on local is taking 4 seconds on server. Shouldn't it take the same time since the query execution is taking place on Atlas server? Or do I need to tweak some server settings?

how to redirect wherever the current url is in django?

[buoyant shuttle]

hey whars your problem

[buoyant shuttle]

wdym, I do not understand

you could use the redirect function, inside of your function abased views

you can reference this, https://docs.djangoproject.com/en/3.1/topics/http/shortcuts/

if you mean in html, a href. instead of placing hardcore links like you would normally do in html you can do this in django. ```py
<a href="{% url <whatever the name is designated to your view in urls.py > %}">logout</a>

[honest dock]

Tsoke I fixed it thank you man

[native tide]

like whenever the user do some stuff the views.py shouldn't change the route

[buoyant shuttle]

coool 👍

[native tide]

instead stay wherever it is before the user does that task

[buoyant shuttle]

so you mean when your user clicks on anything, the views should not change route?

in that case, you can use the redirect() function

[native tide]

yeah

[native tide]

redirect where?

[buoyant shuttle]

wait i just finally understood what your question meant @native tide

If you want your user to do multple stuff on your website without changing webpages, or redirecting urls. Use Javascript

Thats basically what the langauge is meant for, it does the logic in a website.

Django only handles backend, with databases. Retrieve information, and collect. You will need to use the DOM effect of javascript to accomplish that

[native tide]

there should be a way

[buoyant shuttle]

let be give you an example of what i actually mean

[native tide]

i can understand but idk how can I do it

is there any way I can do some django view funtion on clicking a html element?

even by using js

[buoyant shuttle]

yeah it can be acheived using JS thats what is called fullstack development

[tribal tapir]

i like how im trying to do something but i have no ideas to create an app

[native tide]

if you want frontend flexibility, you will have to use a JS framework for the frontend, django as backend API

[buoyant shuttle]

exaclty

[native tide]

i regret not using react from start

now I have progressed a lot already

[buoyant shuttle]

lol

Ive been there

I was making a project for 5 months, almost half way there, then something happened to my hard drive

[native tide]

@native tide do you have solutions for it?

[buoyant shuttle]

lost all my work and rage quitted.

[native tide]

damn

[native tide]

damn bro, same happened to me but I had at least some of it uploaded to github...

it really is a life saver

[native tide]

how far have you progressed?

almost 50% of the project

[buoyant shuttle]

yeah i should done that, i wanted to upload to github after i was done

[native tide]

that's not the way you use github though

I push to github after every feature changes

[native tide]

Well, maybe continue, but you can still implement React (you will have to learn it though). It will take away all your frontend progress

With a django/react project most of the time spent imo is on the frontend anyway

by a large margin

Because all you have to do on the backend is just setup a few API views and your models, some serializers, that's really it tbh

[buoyant shuttle]

tbh learning react shouldnt take you long

you can do it in a week,

[native tide]

yeah but I will have to reorganize the whole project 😦

[quiet granite]

If reorganizing you project is the concern, you can use Vue.js. I haven't used it in any major project but have played with it for a while. You just need to load the Vue <script> tag in your html file and initialize the Vue app.

https://vuejs.org/v2/guide/

[short vector]

When using jinja, if i have a stylesheet in /static, and i want to use it with another static html file in /static, can i do the usual {{ 'static', filename="foo" }} to link it, or do i have to hardcode it in?

it was saying pip not recognised

umm its showing u should consider upgrading the pip version

how to do that?

in your views.py

from django.shortcuts import redirect

 return redirect('/')

[austere cloud]

@granite pasture nope

[granite pasture]

okie thx

pog i m watching one piece as well

88 episode tho

[austere cloud]

I am waiting for my hero academia

[granite pasture]

:O

[native tide]

that leads to the home page

[granite pasture]

ok before i start django i need to google about what is web development

[vernal furnace]

Instead put the page url before the slash

Not the whole url

One min lemme get on my pc

@native tide Redirect works in a lot of ways, but since u only want to return it to the same page add your path before the slash

for example I have this in my urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('todo', views.index, name='list'),
]

[native tide]

dude I have applied the pagination

[vernal furnace]

in views.py

return redirect('todo/')

oh

[plain zealot]

Anyone what can I do in css to keep the page from showing the edges in white

Like it is showing this white edge

[austere cloud]

Have you tried width: 100%@plain zealot

[versed lotus]

it might be body and/or html where you need to set padding/margin to 0

body, html { margin:0; padding: 0 }

[native tide]

@native tide why would you want to redirect to the same page?

[native tide]

so, I have some contents and have used pagination feature. I have added a bookmark icon on each items. when a user clicks on that icon, it works well, but it redirects to page 1

[sullen forum]

Im happy

👍

[plain zealot]

I did that

But when I stretch the page it still shows the white page

And in smaller sizes it still shows the white space

[austere cloud]

@plain zealot can i see your css?
