#

do you need to use something like docker if you are going to store Django on a server?

#

for Deploying it?

#

Or would Django have something built in for that?

quick schooner Nov 4, 2020, 1:52 AM

hello all
i'getting my hand on Django queries
and i am supposed to have 80ish entries for a model
this model have a link in the format following DATE_XXX@YYY
if i do
e_tor = e.filter(boxscore_link__icontains='XXX')
it will only filter those with the format @XXX and not the ones with XXX@YYY why ?
because i want to get all objects where DATE year = 2019 and XXX is present in field

cold socket Nov 4, 2020, 1:52 AM

#

Can anyone help me understand what the problem here is when launching my Flask app using Gunicorn and Docker: https://paste.pythondiscord.com/itutagitoy.sql

#

This works just fine when running it locally on my system

warm igloo Nov 4, 2020, 1:57 AM

#

@cold socket it can't do your import .. my guess is maybe in your dockerfile you're not installing your reqs?

#

you could perhaps bash into your container to see if everything is where you expect it to be but it seems like though it can see app it can't see Stores

cold socket Nov 4, 2020, 1:59 AM

#

Stores is a class in the app.py file

warm igloo Nov 4, 2020, 2:00 AM

#

ah, interesting

cold socket Nov 4, 2020, 2:00 AM

#

and Im importing it in another file called checker.py

#

and theyre in the same directory

@quick schooner are you sure your filtering is correct ? because i tried on my machine, filter still able to find with icontains="XXX" and found example data with "XXX@2019"

quick schooner Nov 4, 2020, 2:38 AM

#

i found my error

#

the TOR@ doesnt appear in my field in fact !

#

my bad

#

there

gaunt marlin Nov 4, 2020, 2:38 AM

#

oh ok glad you figured it out

quick schooner Nov 4, 2020, 2:38 AM

#

i just did right now lol

#

printing everything always work

gaunt marlin Nov 4, 2020, 2:39 AM

yeah debug always help 😄

quick schooner Nov 4, 2020, 2:40 AM

if i show you my models file would you be able to tell me waht to improve ? because i'm really struggling rn on how to model efficiently my models to make simple queries

i have many queries i want to make

#

but a good start would be the following

#

find all Linescores fitlering by Season year and Team abbreviation

#

i am wondering if i really need to have so much sub classes to my main Event class

#

because my Event is linked to a Boxscore which is linked to a Linescore

gaunt marlin Nov 4, 2020, 2:43 AM

yeah let me read over and see

a suggestion when you have troubles figuring out models it's easier to see with a UML diagram of tables

📎 stats_models.png

#

nice !

#

its a mess lol

#

i made a Linescore as a sub of boxscor just to organise better (think it is ) from just having Linescore linked to Event just as betpp class

#

so i want to get all linescores of a team Events from a certain year how would i do that please ?

#

one of the issue i see is i cant filter my Events by team since i dissociated home and visitor Team in event

gaunt marlin Nov 4, 2020, 2:50 AM

#

@quick schooner from the UML you can see that Linescore FK to Team and FK to Event

quick schooner Nov 4, 2020, 2:50 AM

#

yes

gaunt marlin Nov 4, 2020, 2:52 AM

#

@quick schooner for starter if you want to filter by year you can use __year on filter with DateTime or Date data https://docs.djangoproject.com/en/3.1/ref/models/querysets/#year

QuerySet API reference | Django documentation | Django

quick schooner Nov 4, 2020, 2:53 AM

#

so i should filter Event there since it s the only class with a date right ?

gaunt marlin Nov 4, 2020, 2:53 AM

#

yes filter by Event.date

#

i see 2 path you can choose:

Linescore -> Boxscore(boxscore_id) - > Event(event_id).date
Linescore -> Team(visitor_team) ->Event(visitor_team but the FK relation is reversed)

#

so i suggest query by the first method

quick schooner Nov 4, 2020, 2:56 AM

#

ok

gaunt marlin Nov 4, 2020, 2:56 AM

#

because event and Team has opposite FK relation so it's hard to do query on

quick schooner Nov 4, 2020, 2:56 AM

#

what do u mean by opposite foreign key ?

#

i feel that boxscore class is useless

gaunt marlin Nov 4, 2020, 2:56 AM

#

filter(Linescore__Boxscore__Event_date__year=YYYY)

#

reverse i mean if you look at the UML

quick schooner Nov 4, 2020, 2:57 AM

#

ok

gaunt marlin Nov 4, 2020, 2:57 AM

#

boxscore contain fk of event

#

but team don't contain fk of event

#

but it reverse: event has fk of team

quick schooner Nov 4, 2020, 2:57 AM

#

but i could shortcircuit it and fk linescore to event no ?

gaunt marlin Nov 4, 2020, 2:58 AM

#

yeah you can

quick schooner Nov 4, 2020, 2:58 AM

#

ok

gaunt marlin Nov 4, 2020, 2:58 AM

#

i don't know basketball so i'm not too familiar with it's leauge system 😄

quick schooner Nov 4, 2020, 2:58 AM

#

haha its ok dw ^

gaunt marlin Nov 4, 2020, 2:58 AM

#

but yeah have Linescore FK with event is easier

quick schooner Nov 4, 2020, 2:59 AM

#

thats what i thought yes

gaunt marlin Nov 4, 2020, 2:59 AM

#

you can have Linescore.event_id

#

in the real life i think it's the same score usually connected to event leauge

quick schooner Nov 4, 2020, 3:00 AM

#

well in my logic

#

u have event

#

event has a boxscore wich will score all infor relatives to scores like linescore with quarter scores and playerstats also in boxscore

#

but it is overflow yes

#

so o k i load all events

gaunt marlin Nov 4, 2020, 3:01 AM

#

possibly, but database is not my main field, you can ask about designing database in #databases 😄

#

i can only help with framework stuffs like query,... 😛

quick schooner Nov 4, 2020, 3:02 AM

#

i have loaded all games from 2019 now with date__year ='2019'

gaunt marlin Nov 4, 2020, 3:02 AM

#

nice

quick schooner Nov 4, 2020, 3:02 AM

#

now how can i filter with teams ?

#

because my issue is

#

the fk to Team

#

is showing home or visitor team only

#

so i an only filter by home or visitor and not by simple Team

#

like if i have PHI@TOR

#

here visitor is Phila and home is Toronto

#

with my model i can only model from home or visitor team right

#

but if i want to get all games wether Toronto is at home or visitor how can i do that ?

gaunt marlin Nov 4, 2020, 3:04 AM

#

which table represent game?

#

it's event or linescore?

quick schooner Nov 4, 2020, 3:04 AM

#

yes Event is the class for game

gaunt marlin Nov 4, 2020, 3:05 AM

#

@quick schooner use OR or IN statement in your query

quick schooner Nov 4, 2020, 3:07 AM

#

let me check IN

#

is this an AND ?

#

e_tor_2019 = e_2019.filter(visitor_team__abbreviation='TOR' AND home_team__abbreviation='TOR')

#

i tried this

gaunt marlin Nov 4, 2020, 3:12 AM

#

@quick schooner
OR statement https://stackoverflow.com/a/739799/11225821

Stack Overflow

How do I do an OR filter in a Django query?

I want to be able to list the items that either a user has added (they are listed as the creator) or the item has been approved.

So I basically need to select:

item.creator = owner or item.modera...

#

you looking if TOR with OR right ?

#

or is in 1 of those

#

and required both need to be TOR(which is not possible)

quick schooner Nov 4, 2020, 3:13 AM

#

eithe one or other so its a or u are right

gaunt marlin Nov 4, 2020, 3:14 AM

#

nvm

#

it's 1 result

#

you have to use OR 😄

quick schooner Nov 4, 2020, 3:14 AM

#

^^

gaunt marlin Nov 4, 2020, 3:14 AM

#

i posted above how how to use OR in django query

#

use Q objects

quick schooner Nov 4, 2020, 3:15 AM

#

Its working !!!!

#

yes thats pretty efficient and simple indeed

gaunt marlin Nov 4, 2020, 3:16 AM

#

nice

quick schooner Nov 4, 2020, 3:17 AM

#

i tried to mix the three queries

#

where e is the list of events

#

but i still have other years events

#

what is wrong here ?

gaunt marlin Nov 4, 2020, 3:18 AM

#

because you use or

#

the logic is

quick schooner Nov 4, 2020, 3:18 AM

#

ohhh

#

yes of course

gaunt marlin Nov 4, 2020, 3:19 AM

#

(visitor team = 'tor' OR home_team = 'tor') AND date__year=2019 @quick schooner

#

is this easier to see ?

quick schooner Nov 4, 2020, 3:20 AM

#

the AND gives me syntax error

gaunt marlin Nov 4, 2020, 3:20 AM

#

so it should be
e.filter((Q(visitor_team__abbreviation='TOR',) | Q(home_team__abbreviation='TOR')), date__year='2019')

#

django ORM don't have AND syntax

#

and is , in query

quick schooner Nov 4, 2020, 3:21 AM

#

okkk

#

got it

#

works great

#

i cannot thank you enough for sharing you knowledge with me in a sympathic and efficient and patient way 🙂

gaunt marlin Nov 4, 2020, 3:22 AM

#

glad to help

quick schooner Nov 4, 2020, 3:24 AM

#

and now

#

from this list of eents

#

if i want to access the data in the linescore ?

gaunt marlin Nov 4, 2020, 3:25 AM

#

you have list of events

#

and your linescore have fk to events

#

so the logic should be linescore has event IN events

#

so this is where the __in query come in

#

but __in only work with a list

quick schooner Nov 4, 2020, 3:26 AM

#

ok

gaunt marlin Nov 4, 2020, 3:26 AM

#

and you need a list of event id

quick schooner Nov 4, 2020, 3:27 AM

#

ok

gaunt marlin Nov 4, 2020, 3:27 AM

#

to get id list of query you use .values_list('id', flat=True)

quick schooner Nov 4, 2020, 3:27 AM

#

well linescore has fk to boxcore which has fk to event in the current state

gaunt marlin Nov 4, 2020, 3:27 AM

#

at your event query you made you add that

#

now your a variable is a list of id

quick schooner Nov 4, 2020, 3:28 AM

#

ok yes

#

it gives me a query set of Ids nice

gaunt marlin Nov 4, 2020, 3:29 AM

#

@quick schooner oh ok so you have to do

Linescore.objects.filter(boxscore_id__event_id__id__in=a)

quick schooner Nov 4, 2020, 3:30 AM

#

ok i got Related Field gort invalid lookup

maybe check your database

#

what should i be looking for in this case ?

#

i have 3870 Linescores

gaunt marlin Nov 4, 2020, 3:41 AM

#

see if any linescore has event_id = one of those results from a

#

are you using mysql or postgres as your database?

quick schooner Nov 4, 2020, 3:42 AM

#

postgres

gaunt marlin Nov 4, 2020, 3:43 AM

#

can you access your postgres data with pgadmin ?

quick schooner Nov 4, 2020, 3:43 AM

#

yes

#

i have it

gaunt marlin Nov 4, 2020, 3:45 AM

#

for query IN statement of postgres

SELECT  *
FROM    table
WHERE   some_id = ANY(ARRAY[1, 2])

#

you copypaste the a list in array part

quick schooner Nov 4, 2020, 3:46 AM

i tried with one id

#

select * from public.stats_event where id= '107088'

#

and it returns the row correctly

gaunt marlin Nov 4, 2020, 3:47 AM

#

i don't see stats_event column in your database

#

or did i missed it ?

vestal hound Nov 4, 2020, 3:47 AM

#

huh.

gaunt marlin Nov 4, 2020, 3:47 AM

#

oh nvm it's table name

vestal hound Nov 4, 2020, 3:47 AM

#

why are you doing it this way

#

is there a reason?

quick schooner Nov 4, 2020, 3:47 AM

#

yes its table

vestal hound Nov 4, 2020, 3:47 AM

#

like with two separate querysets

quick schooner Nov 4, 2020, 3:47 AM

#

i am beginner

#

figuring the best ways to do queries at the moment 🙂

#

📎 stats_models.png

vestal hound Nov 4, 2020, 3:48 AM

#

like do you need both a and b?

#

or what

#

or do you only need a because you want those IDs to query b

quick schooner Nov 4, 2020, 3:48 AM

#

i m looking to acces Linescore stats from a query set of Event

gaunt marlin Nov 4, 2020, 3:49 AM

#

you can see above he querying for linescore that contain event with year=2019 and has (home_team OR visitor_team = 'TOR')

#

so it should be 2 queries

quick schooner Nov 4, 2020, 3:49 AM

#

queryset of event being games wher etor is visitor and home and year is 2019

gaunt marlin Nov 4, 2020, 3:49 AM

#

a itself contain many filter logics so it need to be separate

#

i'm thinking his database might not has the data satisfied his query

quick schooner Nov 4, 2020, 3:52 AM

#

possibly also

gaunt marlin Nov 4, 2020, 3:52 AM

#

can you access django admin ?

#

you can search from there

#

generate admin of linescore

quick schooner Nov 4, 2020, 3:53 AM

#

not sure how

gaunt marlin Nov 4, 2020, 3:53 AM

#

oh then nvm

vestal hound Nov 4, 2020, 3:54 AM

#

as in

#

my question is

#

do you need the queryset of Event or not?

#

like independent of the queryset of Linescore

quick schooner Nov 4, 2020, 3:55 AM

#

i'm not sure tbh

gaunt marlin Nov 4, 2020, 3:55 AM

#

you should post your logic

vestal hound Nov 4, 2020, 3:55 AM

#

or do you just want the Linescore instances

#

that correspond to certain criteria over events?

#

okay, let me put it this way

quick schooner Nov 4, 2020, 3:56 AM

#

i think i just want and need the Linescores

vestal hound Nov 4, 2020, 3:56 AM

#

say you solve your problem with the above querysets a and b

#

do you need a for anything?

#

okay.

#

can you explain again

#

which linescores you need?

quick schooner Nov 4, 2020, 3:56 AM

#

but i cant filter the linescores with my model

#

lets say i need

#

all line scores

#

of games of 2019 of the team TOR

vestal hound Nov 4, 2020, 3:58 AM

#

okay

#

can you post your models

#

which fields would those be?

#

do you have like a DateTimeField that corresponds to the game date etc.

#

and which model is that in?

use UpperCamelCase for your model names

quick schooner Nov 4, 2020, 4:00 AM

#

ok

vestal hound Nov 4, 2020, 4:00 AM

#

actually this is a relatively major thing

#

it matters in Django

quick schooner Nov 4, 2020, 4:00 AM

#

got it

vestal hound Nov 4, 2020, 4:00 AM

#

normally what you call your classes doesn't really matter apart from being a minor eyesore but I don't know how that would screw with Django's conventions

#

anyway

#

okay so

#

Linescore.objects.filter(Q(visitor_team__abbreviation='TOR') | Q(home_team__abbreviation='TOR'), boxscore__event__date__year=2019)

#

incidentally

#

your Boxscore related_name for the event PK is weird

#

related_name is what the other side calls you

#

so like

#

Boxscore.event -> the Event relating to boxscore

gaunt marlin Nov 4, 2020, 4:02 AM

#

you missed the OR statement

#

now both teams have TOR

quick schooner Nov 4, 2020, 4:02 AM

#

it is confusing mee also i just set it up so that i didnt havee 'clashes' from django

vestal hound Nov 4, 2020, 4:02 AM

#

you missed the OR statement
@gaunt marlin wups yeah, fixed

gaunt marlin Nov 4, 2020, 4:03 AM

#

basic principle of naming in python usually
class: CamelCase
variable, function: use _ for separation

vestal hound Nov 4, 2020, 4:03 AM

#

it is confusing mee also i just set it up so that i didnt havee 'clashes' from django
@quick schooner you probably have clashes for another reason

#

in any case, good naming is very important

#

that related_name is basically asking...

#

what do you want to call the Boxscore models that are related to an Event?

#

and right now you have event.event

#

because you set your related_name to 'event'.

#

oh my GOD you called your related field event_id?

quick schooner Nov 4, 2020, 4:04 AM

#

thats bad yes

vestal hound Nov 4, 2020, 4:04 AM

#

just call it event

#

in your Boxscore model

#

yeah, you need to fix that or the query I gave you won't work

#

alternatively you can change the last filter to boxscore__event_id__date__year=2019, which is...pretty weird.

gaunt marlin Nov 4, 2020, 4:05 AM

#

also in Django don't name field with _id because django will auto add _id at the end of column name
for example:

user_id = ForeignKeyField, django will auto set in database column name = user_id_id

quick schooner Nov 4, 2020, 4:06 AM

#

well since myy model was already confusing me

#

yes i put event_id in boxscore to remberber it was the foreignkey towardds the even id haha

#

ok i didnt know that nice

#

could you provid a better models.py architecture i could use ?

#

i feel that this is way more omplicated how i did it than how it is supposed to be done with django logic

gaunt marlin Nov 4, 2020, 4:14 AM

#

it's not actually related to Django but your database design

You can add using obj["data2"] = data2

#

"data2" would be the key, data2 is the variable storing the stuff after :

Im working though CS50 Web Development. Just to be sure i understand the layout (typing it out without googling helps me commit to memory) My website is bascially an app. Within that app, i have to define the webpages in urls.py and views.py which assigns a url path to each html file and renders the webpage based on which html file is called (respectively). These python files allow for coding in the html file as well as dynamiclly updating paths right?

spiral smelt Nov 4, 2020, 5:19 AM

#

urls.py maps a url to a python function in your views.py

#

The functions in views.py renders the template htmls

#

Also yay to cs50 web

Hi hoping to get some advice.

Is there any good python web framework, that can create a web server while at the same time be able to send via web sockets every few minutes?

toxic flame Nov 4, 2020, 6:04 AM

#

Django & flask sir

#

Is very good

vestal hound Nov 4, 2020, 6:10 AM

#

Django or Flask

#

also note that you'll need a separate library to handle websockets

#

neither of them do out of the box

Then I allowed ssh on port 22 and http on port 80.
I downloaded my code from github.
Downloaded all packages required.
And ran the flask app with debug ttrue for development testing.
The app ran successfully there's no error, but on visiting the public ip the page isn't loading neither the debug is showing the get request made.

does anyone know how i would go about showing the 'print' commands from my script to show up on my html home page when the user presses send? This is my flask app:

from flask import Flask, render_template, request
from My_script import resend_data

app = Flask(__name__)
@app.route('/')
def main():
    return render_template ("home.html")

@app.route('/process', methods=['POST'])
def process():
    # Retrieve the HTTP POST request parameter value from 'request.form' dictionary
    _username = request.form.get('username')  # get(attr) returns None if attr is not present
    _password = request.form.get('password')
    _UID = request.form.get('UID')
    # Validate and send response
    resp = resend_data(_username, _password, _UID) 
    #subprocess.call(["python","myscript.py"], shell=True)
    return render_template("some_page.html", response=resp)
#def response():
#    return render_template ("out.html")
if __name__ == '__main__':
    app.run(debug=True)

cold haven Nov 4, 2020, 11:38 AM

#

you can't use the print() function in an html. It's python

proper owl Nov 4, 2020, 11:38 AM

#

@digital hinge What I usually do is render the same html template but in different view and flash message. Do you only want to let user know login done OK?

cold haven Nov 4, 2020, 11:40 AM

#

I don't know what you are doing.

#

I'm learning this too.

digital hinge Nov 4, 2020, 11:41 AM

#

@proper owl I have a form that the values _username, _password and _UID are being entered. When they click "submit" it processes the script. The Flask terminal shows the PRINT objects but id like to show them on the html page (Ajax maybe?)

cold haven Nov 4, 2020, 11:42 AM

#

send them to the view yeah.

proper owl Nov 4, 2020, 11:42 AM

#

to do it simple you can pass something to render_template("some_page.html", response=resp,uid = _uid, username = _username)

#

and in html template acces it by {{username}} {{uid}}

Hey guys, I'm trying to build a simple Chat application using Django. Found an official Django tutorial online - https://channels.readthedocs.io/en/stable/tutorial/

When I completed part 2, I'm facing an issue. My issue is as below. :

When 1st browser joins a room it works just fine. But the moment a new browser session joins the same room, the first session does not get the messages and 2 messages are sent to the latest browser session.

If a third browser session joins the room, 1st and 2nd sessions don't get the messages and the third session gets all the 3 messages.

I followed every step meticulously but not able to fix the issue.

Can anyone help me, please?

native tide Nov 4, 2020, 11:56 AM

webpage script

ill assume this means javascript

use console.log in the script it will print to the client console

@digital hinge still have problem?

digital hinge Nov 4, 2020, 11:59 AM

Yes, just wanting to show the output of my ython script on my html page when they hit the send button

ok what you want to do exactly

?

digital hinge Nov 4, 2020, 12:00 PM

from flask import Flask, render_template, request

ok is My_script module your own script?

digital hinge Nov 4, 2020, 12:01 PM

#

the home.html has a form that gets a couple of vlues and passes these value to y python script. The server console shows me the print values but i would like them to show on the html page as well

#

yes

nimble epoch Nov 4, 2020, 12:01 PM

#

ok any error?

digital hinge Nov 4, 2020, 12:02 PM

#

the resend_data is the function from My_script that launches. No errors runs beutifully, just no process bar or anything that tells the user its working

#

so i was hoping i could display the print log after 'send' has been press on the 'home.html' form

nimble epoch Nov 4, 2020, 12:04 PM

#

what it does maybe your resend_data method is wrong?

#

what the mehod does? maybe itll help more

digital hinge Nov 4, 2020, 12:06 PM

#

Everything is working. Im just trying to show the script is processing on the client side. So I have a server with Flask, app.py (flask app), that launches the My_script function when the home.html form is filled out and 'send' is pressed. on the Flask run terminal i can see all the objects its 'printing' but i want to show this log as a stream on the html page

nimble epoch Nov 4, 2020, 12:10 PM

#

your resend_data has parameters but im not sure where the problem is because i think the flask server is working good

#

maybe theres something wrong with your own module

#

and im seeing your some_page template. i cant see any method views named download_file

digital hinge Nov 4, 2020, 12:13 PM

#

some_page is the page that appears after the script has completed

nimble epoch Nov 4, 2020, 12:14 PM

#

url_for is usually used for a method name

#

i dont think there gotta be a dot before it

digital hinge Nov 4, 2020, 12:14 PM

#

download_files downloads the zip file i create with the My_script.

#

@app.route('/download')
def download_file():
    #path = "html2pdf.pdf"
    #path = "info.xlsx"
    path = f"{_UID}.zip"
    #path = "sample.txt"
    return send_file(path, as_attachment=True)

nimble epoch Nov 4, 2020, 12:15 PM

#

so theres a dot in here url_for('.download_file')

#

you placed it before your methodview name

digital hinge Nov 4, 2020, 12:16 PM

#

everything works, just want to make this here in "home.html" so show the output of the My_script ```html
<form action="process" method="post">
<input type="text" id = "UID" name = "UID" placeholder="Enter URL”">
<input type="text" id="username" name = "username" placeholder="Username”">
<input type="password" id="password" name="password">
<button class="ui-component__password-field__show-hide" type="button" onclick="text()" id="button">Show</button>
<input type="submit" id = "btnSubmit" value="SEND">
</form>
<script>
<p>{{ output }}</p>

my source for that download function was from here: https://www.roytuts.com/how-to-download-file-using-python-flask/ but it works 🙂

@nimble epoch Any idea how i can View real-time console on a web page with Flask python for the home.html when this is pressed: value="SEND

nimble epoch Nov 4, 2020, 12:27 PM

#

usually javascript used for real-time webpages but im not sure that i got your right?

digital hinge Nov 4, 2020, 12:29 PM

#

so the flask console is the python output. Thats what im after

cold haven Nov 4, 2020, 12:29 PM

#

what type of service are you trying to make?

nimble epoch Nov 4, 2020, 12:32 PM

#

@app.route('/button/')
def button_clicked():
print 'Hello world!' #output in the console
return redirect('/') #output in the webpage

cold haven Nov 4, 2020, 12:33 PM

#

@digital hinge I wouldn't go about writing to a client console at all in that case. I would have an alert in the form of a popup show after pressing a button. Here is a resource for that specific action : https://www.w3schools.com/js/js_popup.asp

digital hinge Nov 4, 2020, 12:35 PM

#

@cold haven What about a process bar then?

#

@nimble epoch that is only showing a print, ot the output from the script My_script.py

cold haven Nov 4, 2020, 12:36 PM

#

I would make a request for a resource on the server by using an ajax post, and then returning it, and then you can put it wherever you want in the view.

#

Maybe you would want it in a popup box.

nimble epoch Nov 4, 2020, 12:37 PM

#

@digital hinge you have create two flask app?

cold haven Nov 4, 2020, 12:37 PM

#

This sounds more like a job for Django.

nimble epoch Nov 4, 2020, 12:37 PM

#

@cold haven no difference

cold haven Nov 4, 2020, 12:38 PM

#

ofc it's different

nimble epoch Nov 4, 2020, 12:38 PM

#

you want to create just a download button right?

digital hinge Nov 4, 2020, 12:40 PM

#

no My_script downloads files, its the wait time i want to show the python console output on the home.html page

nimble epoch Nov 4, 2020, 12:40 PM

#

so you gotta return it

digital hinge Nov 4, 2020, 12:40 PM

#

If i can implement this, that would work : https://discordapp.com/channels/267624335836053506/366673702533988363/773513383890124810

nimble epoch Nov 4, 2020, 12:40 PM

#

you gotta use redirect using flask

#

you want the client download the file then get redirected to the other page?

digital hinge Nov 4, 2020, 12:45 PM

#

the files download when they press the 'send' button and it can take up to 5 min

cold haven Nov 4, 2020, 12:45 PM

#

you want to avoid sending redirects from the client and use a router on the server-side.

digital hinge Nov 4, 2020, 12:45 PM

#

need like a process bar or to show the server console output for the print commands so the user can see the files are downlaoding

nimble epoch Nov 4, 2020, 12:47 PM

#

so...

balmy stag Nov 4, 2020, 12:47 PM

I think what @digital hinge want is to display the logs created by his script WHILE it's running. The solution you just linked seems like a good idea but it's a bit hacky and not optimized. A solution could be to use websocket, but I've never used Flask, I don't know how it can be handled.

cold haven Nov 4, 2020, 12:48 PM

you want to create a download bar for what exactly? requests are almost instantaneous except when downloading GBs of info. @digital hinge

You first need to connect your front (JS) to a websocket Flask view that emits an event whenever a log is created (that's the hard part), when the JS gets an event it displays it in the html page.

def index():
def inner():
proc = subprocess.Popen(
['dmesg'], #call something with a lot of output so we can see it
shell=True,
stdout=subprocess.PIPE
)

    for line in iter(proc.stdout.readline,''):
        time.sleep(1)                           # Don't need this just shows the text streaming
        yield line.rstrip() + '<br/>\n'

return flask.Response(inner(), mimetype='text/html')  # text/html is required for most browsers to show th$

nimble epoch Nov 4, 2020, 12:58 PM

#

oh sorry i dont use subprocess

cold haven Nov 4, 2020, 12:58 PM

#

how else are you going to send requests to the server w/o js is the question, if only you use it for REST I think.

#

you need json objects

nimble epoch Nov 4, 2020, 12:59 PM

#

@digital hinge try it yourself see it works or not

balmy stag Nov 4, 2020, 1:00 PM

#

HTTP is not asynchronous, you call it, it gives you an answer right away, so that don't work I think

cold haven Nov 4, 2020, 1:01 PM

#

back in the day of PHP you would serve a static html from the server and that's it. You would use php forms.

balmy stag Nov 4, 2020, 1:01 PM

#

The link you gave earlier is maybe simpler, you call a view that gives every log you had so far every X seconds, and place the response in your html body

cold haven Nov 4, 2020, 1:01 PM

#

you can send a form in htmI believe, you use SOAP

nimble epoch Nov 4, 2020, 1:03 PM

#

The link you gave earlier is maybe simpler, you call a view that gives every log you had so far every X seconds, and place the response in your html body

@cold haven Typescript needs compilation, it seems a bit heavy, plain JS is enough

i'm used to using high level abstractions in coding so that's what I would go with in any case. No need to reinvent the wheel for smaller tasks even. Especially if you have lots of sample code available that you can copy/past into different projects.

the output variable youve set in the render_template is set to something called index

I have a good resource for setting that up if you want.

No plans for that yet, its just a locally ran server qtm

@nimble epoch no i mean if you want realtime db than you can use firebase for anything

balmy stag Nov 4, 2020, 1:20 PM

#

Here's what I'd make and then I need to get to work @digital hinge:
Flask :

have a 'script' view that calls your script just like you did. Instead of printing the log in the console, write it in a log file (save it everytime you write something). Save this file with a name related to the user (could be an autogenerated name in JS that you put in a hidden field in your form).
have a 'log' view that takes the famous autogenerated name in parameter, and read the JS file named like that, and returns the content.

Front (JS) :
When you submit the form, add a timeout (https://www.w3schools.com/jsref/met_win_settimeout.asp) that calls your log view using ajax (so the window don't reload). And display the answer of your request in a div in your html page. That'd be a 20 lines script at most, if you want I can write it for you.

#

you can use firebase if you want it realtime
@stable kite, firebase or not, you need JS to make the web page dynamic.

#

It can't be achieved using Python only

stable kite Nov 4, 2020, 1:21 PM

#

you can use firebase if you want it realtime
@stable kite, firebase or not, you need JS to make the web page dynamic.
@balmy stag thats for sure

if i know how to add this to my function in the Flask app this may be a solution: ```py

def index():
def inner():
for x in range(100):
time.sleep(1)
yield '%s<br/>\n' % x
env = Environment(loader=FileSystemLoader('templates'))
tmpl = env.get_template('result.html')
return flask.Response(tmpl.generate(result=inner()))

So this question is more a web question than a python question, but maybe you guys have an answer to it. Anyways, so this script running on my python flask server runs the function updateLiveData() much more frequent than once a second, more like every 200ms or so, why is this?

window.addEventListener('load', function()
{
    var xhr = null;

    getXmlHttpRequestObject = function()
    {
        if(!xhr)
        {               
            // Create a new XMLHttpRequest object 
            xhr = new XMLHttpRequest();
        }
        return xhr;
    };

    updateLiveData = function()
    {
        var now = new Date();
        // Date string is appended as a query with live data 
        // for not to use the cached version 
        var url = "{{ url_for('static', filename='log.txt') }}" + "?" + now.getTime();
        xhr = getXmlHttpRequestObject();
        xhr.onreadystatechange = evenHandler;
        // asynchronous requests
        xhr.open("GET", url, true);
        // Send the request over the network
        xhr.send(null);
    };

    updateLiveData();

    function evenHandler()
    {
        // Check response is ready or not
        if(xhr.readyState == 4 && xhr.status == 200)
        {
            dataDiv = document.getElementById('log');
            // Set current data text
            dataDiv.innerHTML = xhr.responseText;
            // Update the live data every 1 sec
            setTimeout(updateLiveData(), 1000);
        }
    }
});
</script>```

@upbeat imp this run because you have used setTimeout()

upbeat imp Nov 4, 2020, 2:10 PM

#

Yes, but not every second, its much faster. Like every 100ms or 200ms

stable kite Nov 4, 2020, 2:11 PM

#

@upbeat imp because 1000=1sec

upbeat imp Nov 4, 2020, 2:11 PM

#

But mine runs faster

stable kite Nov 4, 2020, 2:12 PM

#

no it should not run faster

upbeat imp Nov 4, 2020, 2:13 PM

#

Well it does, like 3-4 request every second

📎 Skjermbilde_2020-11-04_151258.png

#

Changing the value inside setTimeout() does nothing to the delay, even a value of 200000 is same speed

stable kite Nov 4, 2020, 2:19 PM

#

@upbeat imp just get all functions out of eventlistner ()

upbeat imp Nov 4, 2020, 2:19 PM

#

How would this work then?
xhr.onreadystatechange = eventHandler;

#

What triggers it

stable kite Nov 4, 2020, 2:21 PM

#

i think you should first sent the request &then you should wait for response

📎 Skjermbilde_2020-11-04_153131.png

updateLiveData runs to fast

#

setTimeout does nothing it seems

#

Well, it does call the function i guess, but not with a timeout

devout coral Nov 4, 2020, 2:44 PM

#

Well, I think it does call with a timeout I think it is calling itself...

#

Have you tried user setInterval() and taking it out of the function?

#

Have set interval set to 1 second and set it to your function.

upbeat imp Nov 4, 2020, 2:45 PM

#

I will try

#

It only does the GET request once if i put setInterval outside the eventHandler

#

Which makes sense, since there is no loop

devout coral Nov 4, 2020, 2:49 PM

#

Well, no setInterval is suppose to call the function every time on a set interval.

#

As opposed to setTineout which only calls it once

upbeat imp Nov 4, 2020, 2:50 PM

#

Did you mean outside the window.addEventListener function?

#

After this JS session, i will never complain about doing work in C again 🥲 😂

devout coral Nov 4, 2020, 2:51 PM

#

Yes

upbeat imp Nov 4, 2020, 2:55 PM

#

hmm

#

No it only runs it once

#

I don't know how scope works in JS, but the setInterval is maybe outside the scope for the function its calling?

devout coral Nov 4, 2020, 2:57 PM

#

Let me see what you did.

upbeat imp Nov 4, 2020, 2:58 PM

#

📎 Skjermbilde_2020-11-04_155754.png

#

It does fetch the log.txt once on page load

#

but not every second

#

📎 Skjermbilde_2020-11-04_155948.png

devout coral Nov 4, 2020, 3:01 PM

#

Put the set interval inside of the onload event like where the function call is.

upbeat imp Nov 4, 2020, 3:03 PM

#

Like this? Same results, only runs once

📎 Skjermbilde_2020-11-04_160321.png

docker is simply a script that runs in the OS.

quick cargo Nov 4, 2020, 3:22 PM

the DB will use the same amount of Ram as it would normally At least it wont use any noticeable amount more

Docker is alot more than a script

alot more

you could easily say that it is a script in a general sense, would you like to add something that it is? 🙂

would probably all go before i use the word 'script' for docker lol

List of all their products
Clients should be able to order products and pay online if they want . which can be sometime large amounts
App should be available in multiple languages

ehh sounds like something Django would fit reasonably into if it doesnt need to be massively performant per proc

multiple languages is hard no matter what you do but can just be different html files or what ever

but it has everything in the box

For payment Stripe is a pretty good api or Paypal but that depends

do you actually need that performance though

cold haven Nov 4, 2020, 3:31 PM

probably not for small to mid sized apps

near bison Nov 4, 2020, 3:31 PM

i don't know how much difference it makes

this is a small app right?

or a medium one?

so i don't wanna mess up

cold haven Nov 4, 2020, 3:32 PM

yeah, I don't know how they would update info in a database though when they get it. I think you need a database administrator for that sort of thing anyways.

I think the default django admin panel would work for me

what is Django admin panel? a preset template?
@cold haven Yes kinda, you can view , edit and add new entries to the db

kind of like phpmyadmin?

run what ever project you're making

and go to http://your:host/admin

@cold haven Compare to phpmyadmin django admin panel has a lot of {your_name} involved

the admin page is dead easy to use and very hard to get wrong without deliberately doing it wrong

I said if they don't have any knowledge in computers at all, and I'm talking at the microsoft excel level.

yeah

trust me ik of your 'normal manager' level

Serverless can cost a shit ton if you fuck up your scaling

cold haven Nov 4, 2020, 3:47 PM

You definitely want to set it up on a cloud service, that way you don't have to worry about implementing the security yourself. You can just use Encryption as a service.

How and where to start?

quick cargo Nov 4, 2020, 3:48 PM

Serverless's advantage is that you pay for what you use rather than a normal vps or Dedi that you pay monthly

yes

quick cargo Nov 4, 2020, 3:48 PM

Can you send me a link to the tutorial?

near bison Nov 4, 2020, 3:50 PM

would heroku work for me

quick cargo Nov 4, 2020, 3:50 PM

#

you need a SSL key and cert set from somewhere (Cloud flare do it for free) and then give gunicorn the SSL cert and key paths

#

err probably not

cold haven Nov 4, 2020, 3:50 PM

#

you are going to want to have a backup which is probably important for any organization.

repeatedly enter file names. If the user enters the same filename
more than once, look up the answer from a dictionary instead of
counting the words again.

torpid terrace Nov 4, 2020, 4:31 PM

#

@sly echo sets are unordered, so while that's a good idea, it won't always give you the correct result.

#

And strings are iterable, so you can iterate through each character in the string with a for loop, ie:
for char in a:

near bison Nov 4, 2020, 4:38 PM

#

string = "aaabbbccccd"
seen = set()
newString = ""
for letter in string:
    if letter not in seen:
        seen.add(letter)
        newString += letter
print(newString)

This would work , right ?

Can someone help me with JavaScript and Jinja2? When I add Jinja inside a script tag, it throws a lot of errors but runs fine
@nova shadow That's because they are not valid js syntaax

doesnt work :/

nova shadow Nov 4, 2020, 4:42 PM

Yeah, but is there anyway to hide those errors?

@nova shadow idk, there should be a vscode specific way to not show some errors, i am sure though, i don't even know even this is how you should achieve what you want, i haven't seen jinja templates editing js

Hello, is any differences between flask_security and flask_login. im using flask_login should i change it to flask_security?

string = "aaabbbccccd"
seen = set()
newString = ""
for letter in string:
    if letter not in seen:
        seen.add(letter)
        newString += letter
print(newString)

This would work , right ?
@near bison not working

near bison Nov 4, 2020, 5:26 PM

What part ?

sly echo Nov 4, 2020, 5:26 PM

#

function that takes in a string, removes the duplicating letters from the list and returns the new string. The first occurrence of the letter should not be removed.

near bison Nov 4, 2020, 5:27 PM

#

Just wrap this inside a function

sly echo Nov 4, 2020, 5:27 PM

#

if I take the input as "Khaan"
It should return [Khan]

#

first occurrence of the alphabet in a string should remain

#

and the result should be in list

near bison Nov 4, 2020, 5:28 PM

return [string]

#

@near bison

near bison Nov 4, 2020, 5:31 PM

Take string as a param

#

And return the final thing

#

def RumDep(string):
seen = set()
newString = ""
for letter in string:
if letter not in seen:
seen.add(letter)
newString += letter
return [newString]

I'm working on a portable browser experience using pyppeteer/headless chrome. Wondering if anyone could point me towards a pattern example for implementing CSS.takeComputedStyleUpdates & CSS.trackComputedStyleUpdates from ChromeDevTools API.

Seems like it would be much more efficient way for me to get computed styles but I'm having trouble grokking it.

Does Gunicorn expect your Flask application to follow a specific file structure like the Factories or Blueprint structures?

quick cargo Nov 4, 2020, 9:05 PM

#

no

#

it doesnt care about that

#

it only imports the specified target file and get the what ever the variable that contains Flask() instance

cold socket Nov 4, 2020, 9:07 PM

#

For some reason Gunicorn seems to error out on my imports

#

But when I run flask locally without Gunicorn the app runs fine

#

Here’s the error I keep getting. If anyone has any insight into why this could be happening I’d be very grateful https://paste.pythondiscord.com/itutagitoy.sql

#

should I create separate app for authentication in Django?

#

what is best practice

acoustic oyster Nov 4, 2020, 9:31 PM

#

I usually combine authentication with a "users" app. Not totally sure on best practice though.

broken abyss Nov 4, 2020, 9:32 PM

#

user app?

#

u mean registration?

quick cargo Nov 4, 2020, 9:33 PM

#

@cold socket most likely because of the CWD you're running the app in

dense slate Nov 4, 2020, 10:59 PM

#

"app" is probably just a user folder that is registered in the settings.py.

toxic flame Nov 4, 2020, 11:09 PM

#

@broken abyss there is a built in django login/registration / auth system

Anyone ever displayed previews for PDFs/JPG/etc on a django template? I'm serving the file as an HttpReponse but it keeps auto-downloading rather than rendering in the browser

gaunt marlin Nov 5, 2020, 3:19 AM

#

@rain ledge try serving the content as image instead:

return HttpResponse(image_data, content_type="image")

rain ledge Nov 5, 2020, 3:22 AM

#

i'm mostly focused on PDFs to start, this is asking me how to save/open it

#

but i'm hoping that i can get browsers to just open PDFs in a new tab @gaunt marlin

gaunt marlin Nov 5, 2020, 3:23 AM

#

oh ok you want to open in new tab

#

@rain ledge

return HttpResponse(file_data, content_type="application/pdf")

rain ledge Nov 5, 2020, 3:23 AM

#

def read_pdf(filepath):
    pdf_temp_file = NamedTemporaryFile(delete=True)
    in_memory_pdf = r.get(filepath, stream=True)

    for block in in_memory_pdf.iter_content(1024 * 8):
        if not block:
            break

        pdf_temp_file.write(block)

    pdf_temp_file.flush()
    temp_file = files.File(pdf_temp_file, name="zd.pdf")

    return temp_file


def ticket_attachment(request):
    filepath = request.GET.get("filepath", None)
    content_type = request.GET.get("content_type", None)

    if content_type == "application/pdf":
        pdf = read_pdf(filepath)
        response = HttpResponse(pdf, content_type=content_type)
        return response

#

@gaunt marlin thoughts?

#

this still triggers an auto-download

gaunt marlin Nov 5, 2020, 3:36 AM

#

@rain ledge that is on frontend part, to open new tab you would have an anchor link with target attribute

<a href="you_image_or_pdf_url" target="_blank">click here to open new tab</a>

#

you_image_or_pdf_url is url for your HttpResponse views

rain ledge Nov 5, 2020, 3:38 AM

#

<a href="{% url 'view-
file'%}?filepath={{attachment.content_url}}&content_type={{attachment.content_type}}" target="_blank">{{ attachment.file_name }}</a>

@steady owl how are you attempting to run it?

gaunt marlin Nov 5, 2020, 3:47 AM

#

@rain ledge your design on the url path is kinda wrong, here how i would do it:
urls.py:

path('image/<str:image_path>', views.my_image, name='api.my_image'),

views.py:

def my_image(request, image_path):
    # codes
    image_data = open(image_path, "rb").read()
    return HttpResponse(image_data, content_type="image")

and in your template:

<a href="{% url 'api.my_image' image_path=attachment.content_url %}" target="_blank">{{ attachment.file_name }}</a>

you can also implement like so with pdf file

steady owl Nov 5, 2020, 3:50 AM

#

@steady owl how are you attempting to run it?
@rain ledge through the terminal

rain ledge Nov 5, 2020, 3:50 AM

rain ledge Nov 5, 2020, 3:56 AM

#

@gaunt marlin I passed them in as url parameters (?param1=param1&) because it's a full url to a third party website where i'm downloading stored files from. I'm downloading the file then serving it back.

#

i'm able to download the file, the problem i'm having is on the return, it auto-downloads rather than opened in the new-tab as expected

gaunt marlin Nov 5, 2020, 3:58 AM

#

@rain ledge to confirm what causing it first, can you try adding a default image path in your code to see if it will download the image or open new tab?

#

because target="_blank" is how you open new tab

rain ledge Nov 5, 2020, 3:59 AM

#

yeah, target="_blank" is in heavy use on the same template*

gaunt marlin Nov 5, 2020, 3:59 AM

#

does it open new tab ?

#

just a working example for html

<a href="https://www.w3schools.com/howto/img_avatar.png" target="_blank">test</a>

rain ledge Nov 5, 2020, 4:02 AM

#

yeah that opened

Hi

How can I not be forced to write all extending code in every template?

#

atm i write this in every page

{% extends 'base.html' %}

{% load static %}

{% block content %}

#

i love this just to be default behavior of all template files, unless i type something else
