If anyone has used markdownx for django, how do you get images to show?

Hey Folks,
I have a Django aggregation question: I'm trying to figure out how to return the latest child record of a parent entity.
I've Googled and read the docs best I can - I'm here as a last resort.
I've checked these SO questions:
https://stackoverflow.com/questions/15675672/get-the-latest-record-with-filter-in-django
https://stackoverflow.com/questions/17887075/django-orm-get-latest-record-for-group
https://stackoverflow.com/questions/30339490/how-to-use-meta-attribute-get-latest-by-properly-with-pk-in-django
With my limited understanding of Django I can't seem to decipher how to apply these concepts to my problem.
This is my view.py
from django.shortcuts import render
from rest_framework import generics
from .models import Installation, Status
from .serializers import InstallationSerializer, StatusSerializer
class ListInstallationsView(generics.ListAPIView):
queryset = Installation.objects.all()
serializer_class = InstallationSerializer
class CreateInstallationView(generics.CreateAPIView):
serializer_class = InstallationSerializer
This is my serializer.py
from rest_framework import serializers
from .models import Installation, Status
from django.db.models import Avg, Count, Min, Sum, Max, Value
class StatusSerializer(serializers.ModelSerializer):
id = serializers.IntegerField(required=False)
installation_id = serializers.PrimaryKeyRelatedField(queryset=Installation.objects.all(),source='installation.id')
class Meta:
model = Status
fields = ("id", "status", "notes", "date", "installation_id")
class InstallationSerializer(serializers.ModelSerializer):
status = StatusSerializer(many=True)
class Meta:
model = Installation
fields = ("customer_name", "address", "appointment_date", "date_created", "date_modified", "status")
This is my model:
from django.db import models
from django.utils import timezone
class Installation(models.Model):
customer_name = models.CharField(max_length=64, null = False)
address = models.TextField(null = False)
appointment_date = models.DateTimeField(null = False)
date_created = models.DateTimeField(auto_now_add=True)
date_modified = models.DateTimeField(auto_now=True)
def __str__(self):
return "customer_name = {}, address = {}, appointment_date = {}, date_created = {}, date_modified = {}".format(self.customer_name, self.address, self.appointment_date, self.date_created, self.date_modified)
class Meta:
ordering = ('-appointment_date',)
@property
def status(self):
return self.status_set.all()
class Status(models.Model):
STATUS_CHOICES = [
('REQUESTED', 'Installation requested'),
('IN_PROGRESS', 'Installation in progress'),
('COMPLETED', 'Installation complete'),
('REJECTED', 'Installation rejected'),
]
status = models.CharField(max_length = 16, choices = STATUS_CHOICES, default = 'REQUESTED', null = False)
notes = models.TextField()
date = models.DateTimeField(default = timezone.now)
installation = models.ForeignKey(Installation, on_delete = models.CASCADE, null = False, related_name='status')
def __str__(self):
return "status : {}, notes : {}, date : {}, installation : {}".format(self.status, self.notes, self.date, self.installation)
class Meta:
ordering = ('-date',)
get_latest_by = 'date'
What I get returned is this:
[
{
"customer_name": "Dono",
"address": "XXX",
"appointment_date": "2019-08-31T12:00:00Z",
"date_created": "2019-08-22T20:58:09Z",
"date_modified": "2019-08-22T20:58:09Z",
"status": [
{
"id": 3,
"status": "COMPLETED",
"notes": "Another",
"date": "2019-08-23T21:33:23Z",
"installation_id": 2
},
{
"id": 2,
"status": "REQUESTED",
"notes": "Test",
"date": "2019-08-23T21:33:06Z",
"installation_id": 2
}
]
}
]
So I'm trying to figure out how to cut the status result set down to just the latest status. Apologies for bombing this group with code dumps!
vagrant adder
since i don't work with django, i can't tell you what to type
but i think you have 2 options
you can query only last status and put that in json response
or
you can remove unwanted elements in list after querying

Hi there, is possible to get the full qualified URL on code without using request or site? I can get it in a template with get_absolute_url
but that doesn't includes the domain, is a relative address to the object, if you execute the same function to put in a text, I just get the relative URL
I need to generate a qr code from that absolute url, I can generate QRs but need the full qualified URL, any idea?

When using Python + Nginx + Gunicorn and SocketIO I get OSError: [Errno 9] Bad file descriptor as a error in my Supervisor log file
any reason as to why? I had previosuly fixed the problem with uninstalling and reinstalling gunicorn but that didnt work this time
I checked SO and Github but all I found were problems where the OP was closing the socket and trying to emit something then
I have SQLite in my Flask app if that makes a difference

i got data from api and send it to html but the html data doesnt render into html
json_data = url_api.json()
data = json_data["extract_html"]
patent cobalt
How do you "send" your data to the html?
It looks like a template language of some sort and things like the Django template engine will escape html by default to prevent injection
native tide
patent cobalt
Is this Django?
patent cobalt
Right, by default, Django will escape html characters, but you can turn it off if you trust the data and actually want to insert it as actual html
One second
native tide
okay sir
patent cobalt
If this is a single variable that you want to mark as "safe", you can use the safe filter: <p>{{ data | safe }}</p> should do that
You can also designate blocks of the template that have the automatic escaping turned off or you can turn it off globally (probably not recommended)
native tide
Thanks sir! that worked

@keen sphinx oh thank you

Well its quite involved to actually completely deploy a website depending on how exactly you have made it - I assume its Flask/Django @native tide ?
If so the easiest way is probably having a look at something like Digital Ocean for deploying a Flask App
Another option if you only want it to be temporary is to just use the built in web server - but that still requires something like a vps to host it on
keen sphinx
or maybe you just want to host it on your computer but make it available on the internet?

Can someone help
Its my first time using cookies
rigid laurel
How is your Flask currently set up, using Jinja templates or more like a rest api?
late gale
I am using django
late gale
nope
rigid laurel
So a REST API?
what is being shown to the user?
response.set_cookie('my_cookie', 'my_cookie_value') # before returning the response
request.COOKIES.get('my_cookie') # getting the cookie when a new request comes in
late gale
What i mean is
Whenever the user clicks on the icon that changes the background color , It doesn't expire even after refreshing
rigid laurel
So unless you want to do a lot of JavaScript, the easiest way I think would be to set up a new Form/View that takes in an additional parameter of the colour, and have that set the cookie in the response
I think is the easiest way
hoary spruce
Okey I'm kind of getting lost right now. I'm using Flask, and I generated a page with inputs from a DB. But I want to have a button on my page, that takes the input from an input entry. And if the button is pressed, it runs a function. But without refresh or going away from the current page I'm at.
Is that possible?
rigid laurel
Its a problem that requires JS to solve
hoary spruce
So I found this:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type=text/javascript>
$(function() {
$('a#test').bind('click', function() {
$.getJSON('/background_process_test',
function(data) {
//do nothing
});
return false;
});
});
</script>
<div class='container'>
<h3>Test</h3>
<form>
<input name="reason">
<a href=# id=test><button class='btn btn-default'>Test</button></a>
</form>
</div>
@main.route('/background_process_test')
def background_process_test():
print("hello")
return "nothing"
And that worked
But when i try to get the input from reason:
@main.route('/background_process_test')
def background_process_test():
reason = request.form['reason']
print(reason)
return "nothing"
It doesn't actually print

I know that's a bit of off-topic but I don't really have anyone else to ask about this.
So, I'm using bootstrap on my website.
Trying to implement modal popups
Copy-pasting this code to one of my pages (I tried variations as well) and it refuses to work even though it works with my code in their test environment.
Can someone help me figure what I am missing please?

What exactly doesn't work? The modal doesn't appear when you click the launch button?
frigid egret
That's just weird, I've tested it on another machine in the same project and it works fine...
@still briar Exactly

Check what webbrowser you tried in and check the F12 console for any error messages.
frigid egret
Did that, no errors

Different webbrowsers?

Same behavior

But you said it works on another machine. Is that using a different webbrowser, or are you saying on your computer specifically it doesn't work in any browser?
In either case, it's hard to debug without your source code.

Yea, the source code is the one I linked. But nvm, I've got a friend figuring it out.

Hey guys
I'm doing a uni project , we have to build a web survey for our client . The problem is , nobody in the team has web Dev skills for front end. Backend is fine. What do you guys recommend we do?
junior cloak
@native tide not even html? honestly if nobody has the skills and the answer can't be "learn the skills" why not just use something like google forms, airtable, etc. to embed a survey? your backend folks can, if they want, use the apis from those services to still grab/do something with the survey results pragramatically if need be

@junior cloak unforunatly those apis are expensive! and not super automated
we will learn front end skills xD

hey everyone - anyone in here who knows Django ever seen request.site append the text [default] to the site name when using it in a view? For some reason on my prod server request.site is coming back as mysite.com [default] instead of just mysite.com and it's messing up the success/cancel URLs for my payment system
protocol = request.scheme
site = request.site
success_location = reverse('checkout_success')
cancel_location = reverse('plans')
success_url = f'{protocol}://{site}{success_location}'
cancel_url = f'{protocol}://{site}{cancel_location}'
works fine on dev but on production it generates a URL like https://mysite.com [default]/plans/checkout/success/ which obviously is not right lol
brave otter
^ That's resolved. Turned out to be a setting in my wagtail site settings which was interfering w/ the default Django sites framework. I switched to using request.get_host() instead of request.site to get the hostname.

I'm building a Flask web app with Flask/SQLAlchemy, I kinda wanna make something with Golang - is it reasonable to try and do my auth/user management there, or is it just gonna be impossible to get everything to talk to each other neatly?
junior cloak
@rigid laurel assuming you're handling auth in a sensible way, sure, if you want to. auth standards are pretty much universal, not unlike how your REST API made in python and one made in Go could be identical, compatible, etc etc.
another alternative, if users will mostly be using a browser or something, is to just... not worry much about it, and let firebase handle google auth or whatever social auth you may be interested in. (and then use the auth data from wherever you want)
if you're rolling some sort of session- or token-based system of your own (be careful) same thing -- nothing inherently incompatible unless you create a weird api for it

Anybody here familiar with django channels V2 and have time/ the desire to help me with a small project?
Im currently trying to embed matplotlib's webagg backend into django using django channels as the websocket.
Im having an error where the js side of the websocket doesn't seem to receive the messages. As a result, matplotlib doesn't draw anything.
AFAIK matplotlib comes with its own JS side of the websocket and should just be plug and play with the backend, but I'm new to django channels and websockets in general.

I think I've narrowed it down to a problem with async in the consumer.py

gleaming herald
Thanks
It's because of your reasons
I am using FASTAPI
that too in production
Earlier we used to use flask
even though flask works well with nginx
junior cloak
yeah i used flask for years
gleaming herald
I tried FASTAPI anyways
junior cloak
flask is beautifully-designed but these days sync vs. async is a big deal
gleaming herald
little peculiar for doubt solving as the official docs is all we have
I don't know how to use async
maybe will dig it in later
I am using async obviously
but not the core functionalities
like the server which sends the request still waits for the response
and it takes time
one more doubt is there some kinda timeout for FASTAPI @junior cloak
Because sometime the response would take around 2 mins
Hope it handles well
junior cloak
uhhhh
what on earth is taking your api 2min to respond haha
not much should take longer than a second or two 😛
gleaming herald
I'm doing some processing depending on the input file
and the file I'm handling are more than 6GB
🤷
Any advice for such large files ?
junior cloak
is most of the time just spent dealing with the file upload, or with the client waiting while you process it?
(what sort of files are 6gb in size and what processing are you doing haha)
gleaming herald
client waiting while I process
you are not gonna belive
but it's csv files 🤣
uploading time is handled by the frontend team 😛
Apparently each file has around 20M Records . . .
junior cloak
in most situations, the API returns instantly with something like a job ID, and then contiues to process normally in the background. the client can make a request with the job ID to get the results later
this is assuming you're using just the REST API... if you have a webpage or something you can use websockets
gleaming herald
do you have a sample code
for things like this
I'm using REST API
Yes this would be best @junior cloak
JOBID thing
is there any webpage / sample_code/ youtube video
junior cloak
the concept isnt too difficult but implementing it varies. when you are doing this processing, are results saved to a database or anything like that? is the process being managed in any way, to see if it failed/succeeded, etc
or is it just... someone hits your API, you do a bunch of work right there in the endpoint handler, and then return it
junior cloak
haha yeah that's what i was worried about
gleaming herald
it can't be done if it's latter ?
junior cloak
implementing this isnt hard but it could seem that way if you arent doing these other things
no it can, it just will seem like more work if you arent already doing things like storing job status somewhere for retrieval and whatnot
but first, here's the most basic way to run tasks in the background in Starlatte/FastAPI: https://www.starlette.io/background/
you just put it into a BackgroundTask object basically and your API will return and not block but do the work. convenient. however that doesnt help you if someone wants to retrieve the result later.
junior cloak
to do that, you need to create an ID for each job, store it somewhere, give it a status (like 'PENDING' or something), update that status from your background task based on how it goes (update it to 'SUCCESS' or 'FAILED' or something), and then have another API endpoint that expects the user to give you the task ID and have it pull that job result from wherever you've been keeping track of it
junior cloak
haha sorry
yeah this might be too complicated currently haha
async doesnt help you much here
junior cloak
maybe for the moment you just keep the connection open and hope it doesnt disconnect 😛
junior cloak
are you using uvicorn?
gleaming herald
yes
junior cloak
then yeah it shouldnt be timing anything out inherently
junior cloak
the API client might have its own timeout, depending on what you are using. a terminal one i use defaulted to 30s
but the others i use dont timeout by default. and i just tested waiting like 3min for a response from a starlette endpoint. not ideal but it's probably simplest for you currently 🙂
gleaming herald
Okay !
Thanks @junior cloak

so i have a site similar to kahoot where there is a quiz game and studnets playing on thier phone, with django channels, how can i make it so when a student submits an answer, a http request is sent to the server of the users answer and then how can i establish a websocket with the site that has the actual quiz and the server so that when the server receives an answer from a student, the server sends the answer to the quiz thing

how do I run the fastapi thing infintely without command line with uvicorn
like for now i run it with uvicorn on comandline
uvicorn main:app --reload
and when the cmd stops
the server also
any other way to do
that will make it run independent of the cmd

so the cmd needs to be on
what if there is power failure
and server is done
how do I manage auto restart then
@unborn terrace
unborn terrace
Redundancy is a solution
Server's auto restart is managed by the server provider
(considering you configured a supervisor or something equivalent, or that it has been managed for you, to automatically restart the app on reboot)
gleaming herald
Alright
native root
screen is my goto for it, and you can do other things like hook it up to systemd
Others suggest tmux, basically they make sure your terminal session persists, but only systemd and similar will ensure that your application persists over restarts

@gleaming herald where do you plan on deploying FastAPI? a linux server, etc? if you'll be deploying to a linux vm somewhere setting up a systemd service is best and not particularly complicated. if you're using docker or something, this is different but also handled for you. or other various platforms. i still love using Heroku while in development because you can 'git push' your project and they do the rest and deal with failures, restarts, new versions, etc
junior cloak
@gleaming herald here's a sample, working systemd service file for a uvicorn/starlette/fastapi app: https://gist.github.com/notdaniel/3c0f0788a142ad6d60f11219076927f5
this would work on your centos box as well as any linux server with systemd. just dropping that file into either /etc/systemd/system for the server itself or ~/.config/systemd/user/ to run it just for your user. it now be controlled by systemd and by default will start the app on startup, restart it if it dies, etc

ruby palm
Hi
I got a question
This is more about design practices
I use classes in CSS and ids in Javascript
So you will see an <input class="checkbox-list" id="checkboxList" type="checkbox"> in my html document often
Is that a good practice?
Or you consider better to just do <input id="checkboxList" type="checkbox"> and use ids whether in js and css?
still briar
Ids allow you to specify which button to use in js. Without it, you'd either have to search for the button you want or generate it.
ruby palm
Yes I know
But what I actually mean is
Do you consider good to have both classes and ids in one element, to modify it through its class name in CSS and to modify it by its id in javascript? Or in that case do you consider better to just have an ID and work with it both in CSS and JS?
native tide
It could be confusing. To mix both id's and class.
But why would you have class and a id first of all? @ruby palm
keen sphinx
does anyone here have experience with MDL? specifically organizing grids
(Material Design Lite)
Nevermind, found the issue
steel tiger
Any way I could add CI to an api running to test it?
native root
Since ID's are unique, or at least using them non-uniquely leads to a large amount of problems, ID's should be used when you're intending to target a single, specific element. Classes are intended to be used across a variety of elements. If you're only targeting that one element with a class you should probably be using an ID, but if there is a case where you might want to target multiple you should be using classes.

@steel tiger
Yes you can, travis ci is a good one

@vagrant adder That wasn't the question
vagrant adder
what do you mean CI to an api then
rigid laurel
You can use Travis to run unit tests as part of the build. As Saki said
vagrant adder
that's literally what i sad
CI's are made to run tests
you can use unittest or pytest to run and make tests

@vagrant adder @rigid laurel I have a flask api
I have a ci
How do I test the flask api using the ci
rigid laurel
I mean, this is pretty basic stuff that is mostly suited for following with a tutorial I've only used Jenkins myself, not Travis but this seems like a perfectly reasonable guide from Google - https://blog.travis-ci.com/2018-01-25-what-is-ci-part-2
Just write your tests and add a script

steel tiger
How would you say it then
steel tiger
So you know what a restful api is, yes?
rigid laurel
you test APIs the same way you test most code
https://flask.palletsprojects.com/en/1.1.x/testing/#testing-json-apis + https://blog.travis-ci.com/2018-01-25-what-is-ci-part-2
What are you asking that isn't in broad terms covered by these two pages?
@steel tiger
steel tiger
What is the correct way to run a unit test on a Flask RESTful API that can be properly integrated into a CI platform. I know what a CI is and I know what a unit test is.
Would it look similar to this built-in requests-like feature of Flask/Werkzurg: py def test_main_page(self): response = self.app.get('/', follow_redirects=True) self.assertEqual(response.status_code, 200)
@rigid laurel
rigid laurel
You need to set up a client that executes the requests for you
def test_empty_db(client):
"""Start with a blank database."""
rv = client.get('/')
assert b'No entries here so far' in rv.data```So they'd look like that
@pytest.fixture
def client():
db_fd, flaskr.app.config['DATABASE'] = tempfile.mkstemp()
flaskr.app.config['TESTING'] = True
with flaskr.app.test_client() as client:
with flaskr.app.app_context():
flaskr.init_db()
yield client
os.close(db_fd)
os.unlink(flaskr.app.config['DATABASE'])```You mean a test framework?
rigid laurel
Assuming you're using pytest you define a client that configures the app for you
steel tiger
Yes
rigid laurel
and then that client is what executes the requests as a fixture - the article I linked explains it better than I can I think
with my_application.app.test_client() as client:
with my_application.app.app_context():
my_application.init_db()
yield client
That is the important part of the above code snippet

looks like that right now

the larger the text size the higher up the left side moves
for some reason if i make it stretch, it looks like this instead:

Is your flex grid in row mode?
never mind
it's because of your "justify-content: flex-end"
If you take a look at the div's containing your two sets of buttons, you'll notice that the second one has space above it (probably)
You should pick "center" instead, for what you're looking for
and if I'm not remembering just right, https://css-tricks.com/snippets/css/a-guide-to-flexbox/ ought to help you
keen sphinx
@CSS savy people: do you still discover new things in the language after a couple of years with it?
native root
@keen sphinx yes, yes we do ;-;
@strong talon align-items: center, my bad. Tested it on your fiddle
Did you know that if you've got a 3d-render-spaced div, (via translateZ(0) or a perspective: application), and it's height is set to a floating point pixel value (via vw, for instance) in firefox there's a mismatch of round() vs floor() that results in single-pixel holes between the divs?
strong talon
What
keen sphinx
no, but I'm not CSS savy, so it doesn't surprise me
keen sphinx
tbqh I'm a novice and my head can't predict how properties will interact with each other, and I don't know how to plan the HTML part too well

I always tend to think in boxes that group things

strong talon
Css is really strange to me
I'm like wow, I'll just use this property
It'll look so nice!
And then everythings of center
native root
It's a classic
Just remember, css comes from the era of IE6, and has not shaken off all of the related mess yet
strong talon
i think the main problem is thatthe owo isn't aligned to the bottom of the a tag
i reverted it back to flex-end
the owo is like
floating
is it a problem with the font?
yea its probably because there's an extra space below and the larger font size makes it wack
strong talon
itsnot a super big issue but its off center
and if i have another link on the left side its really obvious
coral sorrel
which part isn't centre
coral sorrel
hm
coral sorrel
is this vertically or horizontally centred
coral sorrel
seems to be vertically matching
if the image isn't loading for you (because discord is having issues atm) then just open it externally
strong talon
ok
hm that's strange
in ur image it seems to line up but in mine it doesn't
this jsfiddle right?
coral sorrel
v6 isn't lining up now, no
the cause of this is
.header div {
align-items: centre;
}
if you change align-items to baseline it'll realign to the base of the divs
coral sorrel
sounds right
this is because align-items is important for anything using flex
if you don't use flex, the other method is to use line-height
but by default it should arrange to baseline and is only something people tend to play with when wanting to ensure consistent vertical centering
strong talon
default was stretch i think
ohhhh
i was using flex-end before
but baseline apparently adjusts for where the letters sit

how come most sites put a ghost button/text button on log in or sign up and a fully filled button on sign up?

is there a nicer solution to not having a gap because of the fixed width other than make a pseudo-bar?
my normal solution is to make another bar, except its completely transparent and position: relative
that way elements below are moved down the right amount
if i specify the height i can just put padding-top
but that might lead to issues as well
native root
Part of your issue is that your logo text, by virtue of being lowercase, is naturally offcenter
The gap issue's solution is position: sticky and position: -webkit-sticky
strong talon
oh, okay thanks
i remember there being a super complicated script for this before but i couldn't find it

anyone familia with django?
patent cobalt
A bit, what do you want to know?
native tide
I have a django question- if you are having a rest API run side by side with a web application, is it proper convention to have the API its own "app" within the django project?
patent cobalt
Yes, I'd say so. In fact, it's not even the case that your entire web applications has to be one django "app"; sometimes it makes sense to split it up into logical modular parts.
native tide
ok, thanks for answering. its a bit to learn with django, but I'm enjoying it
I made a good sized app with flask, so that made the learning process for this a bit easier
patent cobalt
I'm still learning Django and it's a lot of fun. (I'm not a webdev, so all my Django projects are purely for fun.)
For our new Python Discord website, we use the Django REST API framework
It lives in its own app and on its own subdomain
native tide
I'm in the job hunting phase and I've read that django is valued quite a bit more than flask, hence my push towards learning it lol
oh very cool, I haven't seen the new site
patent cobalt
It's not up yet, we're still working on it
native tide
ah gotcha
patent cobalt
There's a test version up on https://django.pythondiscord.com/
The api is for internal use, though. Our bot communicates with the database over the API.

the help channels may be able to help you out better
balmy forge
js?
balmy forge
map can return indexes as well, like enumerate
But not sure if it's the scope of this server
native tide
but to answer your question, you can just go through the loop, and if an item meets your criteria, you can add it to an empty list that you return at the end
ah I read it wrong, you want the index numbers. so you'd need a little more added to that
honest flame
yeah, like for that ones i need to push the ones into a new array
patent cobalt
@balmy forge We do help with technologies related to webdev in this channel (including js), but sometimes a server for general programming or js in specific just has more users that can help with such a question.
balmy forge
Thank you for the clarification

(I don't know any js for instance)
balmy forge
If you look closer into .map() method
(method) Array<string>.map<void>(callbackfn: (value: string, index: number, array: string[]) => void, thisArg?: any): void[]```A simple demonstration of how you use it is like this
const myList = ['a', 'b', 'c', 'd'];
myList.map((x, i) => console.log(i, x));
it'll outputjs 0 a 1 b 2 c 3 d
You can take it in and then return it in the map, so a better example you can use is like this
const myList = [1, 2, 3, 4, 5, 6];
console.log(myList.map((x, i) => [x % 3 === 0, i]).join('\n'));
You'll get thisjs false,0 false,1 true,2 false,3 false,4 true,5
Getting them is very easy via the use of .filter(), this time you also has the index from it
To expand the above example, here
const myList = [1, 2, 3, 4, 5, 6];
const results = myList.map((x, i) => [x % 3 === 0, i]);
const filtered = results.filter(([value, index]) => value);
console.log(filtered.join('\n'));
You'll get js true,2 true,5
Does that answer your question @honest flame
You can chain it alright
myList = [1, 2, 3, 4, 5, 6].map((x, i) => [x % 3 === 0, i]).filter(([value, index]) => value)```No worries, if you need help, don't hesitate to ask
Another way is to do index inside the filter
All of the code i posted are working codes, you can try running them as snippets
honest flame
yeah cool

Hello, I'm writing a simple personal website using Django to periodically send me Web Push notifications. I need to generate notifications periodically, my understanding is that normally things run periodically Django looks at tasks.py, or on a Linux server using CRON?

is it at all possible to have a script outside of django still interface with the ORM? Django will be the user interface, and I'll have scraper using asyncio, as well as some added logic for alerting and some light analysis functions. both scripts would run at the same time, both of which reading and writing to the database. This is a bit beyond anything I've done before, and I don't know if this will require some frankenstein solution. thanks!
patent cobalt
It's probably best to expose an API to your other script from your Django back-end
You may associate that with external services, like the public APIs you're used to, but it basically means providing an interface for other applications, like your scraping script, to your Django application.

Things = Thing.query.filter_by(owner_id=g.user.id, is_public=True)``` Is there any way to use or in Flask SQLAlchemy neatly?@rigid laurel what do you mean "neatly?"
rigid laurel
apparently you can do query(or_(Model.property == Val, Model.property2 == val2))
but I would just prefer to do two separate queries
native tide
I don't know if this answers your question but this might point you in the right direction,
but if you use filter instead of filter_by, you don't have to just use the object attributes
but you'd have to use database.session.query(TheObject).filter
so instead of attribute=4 for instance, you can have AnotherObject.attribute == value
as for having an or, I've read you can use a | in the parentheses, and a filter on each side
rigid laurel
Yeah, I think thats the solution I saw. I don't love it but I'll either go with that or just 2 queries
I was just hoping I was missing some obvious aspect of filter_by
native tide
what I did which probably isn't proper is just do two separate queries, and then add both lists into a set
I've only done one project utilizing flask/flask-sqlalchemy, thats just what I did to get my project working

Architecture question - If i wanted to build a web service that provided multiple IPC interfaces to a business logic/persistent layer, would I build a separate server per IPC protocol?

surreal thicket
summarizing my response from elsewhere: no, you can put it all on one webserver
but im also wondering if thats even wise -- maintaining 3 separate implementations of an API could be a lot of work

Okay I'm reading the documentation for beautifulsoup, which I understand is here: https://www.crummy.com/software/BeautifulSoup/bs4/doc/
The documentation seems to have a lot of information about parsing HTML. I don't see a lot of information for generating html programmatically. A simple example: how would I use it to generate a table from a list of lists, where the outer list is the table and the inner list is each row?
in the gist I provided, I do that by:
html.table(['this', 'is', 'a', 'header', 'row'], [['this', 'is', 'a', 'body', 'row'], ['another', 'body', 'row']])
>>> html.EscapedContent(...)
doing str(html.EscapedContent()) would give me the generated HTML markup
Doing this results in a blank page:
from bs4 import BeautifulSoup
class MainHandler(tornado.web.RequestHandler):
def get(self):
soup = BeautifulSoup('', 'html.parser')
soup.title = 'This is an example title'
soup.body = '' # soup.table() ???
self.set_status(200)
self.write(str(soup))
self.finish()
How would I insert a table into the body using beautifulsoup?
It also didn't write a title in the html header

@sacred perch did you commit and push the requirements.txt ? Do you also have the Python buildpack added to the project ?
sacred perch
yes I did and pushed it
unborn terrace
Show the buildlog
sacred perch
what is buildpack
unborn terrace
vagrant adder
It sounds like you need a buildpack @sacred perch
What does your Procfile look like?
sacred perch
procfile has this
web: gunicorn deploy:app
okay so now I have created the app with build pack as mentioend on that link
but the app is still crashed so which logs should I show you?
vagrant adder
What does your app structure look like
vagrant adder
Ah
Well, deploy is not needed then
web: gunicorn app:app
After you change that, push it to a heroku repo
git push heroku master

@marsh canyon flexbox is used quite extensively
marsh canyon
okay
sacred perch
flask
flask-cors
flask-pymongo
gunicorn
jsonify
this is requirements.txt
marsh canyon
is css flex box and css grid used for same purpus?
or do they have different functionality?
sacred perch
@marsh canyon yes bro they are both for laying out your UI
marsh canyon
are they used together or alternatives to each other?
sacred perch
https://css-tricks.com/quick-whats-the-difference-between-flexbox-and-grid/
this site is really good resource for such things
yes you can use them separately or together
sacred perch
gird is used when you have a layout already specified and flex is something you use for your smaller componennt but still its your design choise

pip install -r requirements.txt is the command
otherwise it's expecting a package-version pair, pip==19.0.1 for example

hi can I run any python script using php exec()
?
grave latch
@vagrant adder even it contains matplotlib graph
grave latch
@vagrant adder thank u..
But I have a question does the webserver I will run my script have python lib installed beforehand or what how does it work @unreal python
@vagrant adder
vagrant adder
python --v
grave latch
I mean do they have matplotlib
vagrant adder
Is it linux or windows
grave latch
windows
vagrant adder
Oh no
pip list
Then you have to search
On your own
On linux it's pip list | fgrep -i 'matplotlib'
grave latch
I know php & python separely. Never used python on website. I am sorry I need a little bit of explaining.
my whole website in php
I just need to run 1 python script
I searched on internet they said use php exec().
What is the thing about linux/windows?
I thought websites are websites. DO THEY HAVE OS?
@vagrant adder
vagrant adder
Heroku offers free small linux servers
grave latch
I am completely new to this sever thing. You are being very helpful. I just have few more qestion
grave latch
how do i connect linux server to my php code.
vagrant adder
Yes
grave latch
can I access database from linux server?
vagrant adder
Yea, you'll need a program of yours that connects or some other software that acts as a program
It depends which database
grave latch
do I need to pay for webhosting.
I am using a free one. It says exec is disabled
@vagrant adder
vagrant adder
Which one
grave latch
vagrant adder
Switch to heroku
grave latch
ok... I think I can try to do the rest
before this I was thinking about learning flask or django

Hi there, I'm encountering an error from trying to import some objects from a module.
I'm getting the error ModuleNotFoundError: No module named 'notetaker.web_ui' even though the syntax seems correct... basically I need to go up one directory level, go into another package, and access a module. The full structure is opened on the image on the left. Any bump in the right direction would be appreciated. thank you

and if I change the import line to from ..web_ui.models import Category, Post I get back ValueError: attempted relative import beyond top-level package so I feel kindof stuck on what the solution is

btw, if you use an IDE like pycharm, it will highlight if your syntax is incorrect

But if you're someone like me, you'll look at the funny squiggly lines and disregard them in favor of running the damn program anyway

pycharm has several levels of highlighting, with escalating levels of seriousness
the syntax stuff like this is its own color, while logical errors are another

Hi all
I need some help figuring out the cause of an error
'User' object has no attribute 'get'
Problem is, lately I haven't touched User and anything related to it.
Tried disabling some connections of User to other objects and it didn't help.
unborn terrace
Error is pretty explicit
frigid egret
I know. As I'm saying, haven't touched User and anything related to it lately, and I don't see any case where It has this attribute.
frigid egret
Worse is that log doesn't point me at the file and/or line with the error
unborn terrace
We do not know what you are talking about at all
frigid egret
Ask
unborn terrace
Give information about your problem
frigid egret
Ye, I was about to, geez
So my user derives from custom AbstractUser class
class User(AbstractUser):

username = models.CharField(max_length=150, unique=False, blank=True, null=True)

_normalize_phone = re.compile(r'(\s{2,}|[a-zA-Z]+)').sub
return _normalize_phone('', phone)
okay so that's Django, tell it next time
unborn terrace
what you are wanting to do is probably User.objects.get
frigid egret
Should have said first
So, here's the only case where I actually found it. Which, I have to add, have been working before, and for quite some time
def profile(request):
"""
User profile page view.
"""
template_name = 'shop/profile.html'
if not User.is_authenticated:
return redirect(reverse('accounts:login'))

user = form.save()
update_session_auth_hash(request, user) # Important!

return redirect('shop-home')
else:
messages.error(request, f'Please correct errors {form.errors}.')

form = PasswordChangeForm(request.user)
user = User.objects.get(phone=request.user.phone)
context = {
'orders': Order.objects.filter(phone=user.phone),
'form': form
}
return render(request, template_name, context)
@frigid egret User.is_authenticated is a nonsense here
frigid egret
It's a view btw
unborn terrace
It does not, because you are checking a class attribute here
(or property, or whatever)
That is, it will always have the same value, in that case it will always satisfy the condition
frigid egret
So, I am getting a user object based on their phone field
unborn terrace
What you have to check is the is_authenticated property of the user object. And that user object is request.user
frigid egret
I get it
unborn terrace
also, why are you doing user = User.objects.get(...) ?
You are basically saying “give me the user that is that user”
Just use request.user, do not query it again
frigid egret
hold on a sec
This view isn't a problem actually. I've just double checked and it works fine.
Maybe there's a better way to write it, as you are saying. But it works nonetheless
unborn terrace
Try accessing your view without being logged in, you'll see
You will not be redirected to login view
unborn terrace
Indeed
because you are not checking is_authenticated correctly, as I stated in previous messages
frigid egret
Ok, 1 sec, let me fix that
Now works fine

@frigid egret this form = OrderForm(request.user, request.POST) does not make sense
frigid egret
Ok, I have my doubts about this one cause it's something I don't entirely understand
unborn terrace
Use this instead
form = OrderForm(data=request.POST, initial={
'phone': request.user.phone,
'first_name': request.user.first_name
})
Yeah read Django's ModelForm doc
frigid egret
Before, I had an error that form gets referenced before assignment
So I googled how to do it and got this line from some SO post. But still didn't quite get how it should work
unborn terrace
Do not, ever, copy SO's anwsers without fully understanding them
frigid egret
I try doing that. But sometimes it's hard to find an actual explanation, especially since i'm still not even a junior, just learning
unborn terrace
Still make the effort to understand, that's how you learn, and how you avoid ending-up with code you do not have control over
frigid egret
It still doesn't work... let me find the error
Ok, now this is really frustrating.
haven't seen anything like that before
Do you have any idea?
Ok wait, that's double weird. Tried it again, and i get the same "'User' object has no attribute 'get'
" error again
remote marsh
File "C:\Program Files\Python36\lib\wsgiref\simple_server.py", line 35, in close
self.status.split(' ',1)[0], self.bytes_sent
AttributeError: 'NoneType' object has no attribute 'split'
probably object is not being created.
frigid egret
That error has been happening randomly lately but it doesn't actually break anything. And I couldn't find solution anywhere so I skipped it. Know it's not the right way to do it but I can't really sit and wait forever.
remote marsh
status = self.status
print(status)
splitting_status = status.split('
print(splitting_status)
that's cool. however you might face troubles later on.
frigid egret
wait-wait
remote marsh
I wanted to highlight that print statements are the best debuggers
frigid egret
Can we get back to that User error again please, cause it's still there?
I'll post it again, in case there's something new in log this time
@unborn terrace
@remote marsh Oh dude, sorry. I thought you're Solon. Didn't read the name 😛
remote marsh
humbled that you would think that 🙂 @unborn terrace is pro(grammer).
alright, I'll die now 😛
frigid egret
Nah, I just continued talking like you were the same person
Didn't mean to say I don't want your input
Do you have any idea what might be causing this error?
remote marsh
somewhere you are adding methods, maybe adding GET to it will work.
methods = ['POST','GET']
remote marsh
like in flask the syntax is something like this
@app.route('/script',methods=['POST'])
so adding get works when get requests are made
sorry, I have just barged in and have no context.
frigid egret
You can scroll up, I've posted all the relevant info previously
Well, as I'm saying, there's no error now but when I send form, it doesn't create an order object.
remote marsh
try debugging it by placing print statements wherever object is initialized, some updation is made, and object is returned. see what kind changes the object is going through. if the final object has relevant values, it is not being given as an input.
return render_template('index.html',combined_list=movie_dict) # flask way.
now I can use combined_list using jinja variables.
frigid egret
Ok, so it prints me order_items variable
But won't print items from for in loop. So it stops before reaching that part for some reason
@remote marsh
def order(request):
form = OrderForm(data=request.POST, initial={
'phone': request.user.phone,
'first_name': request.user.first_name
})
if request.method == 'POST':
mutable_request_data = request.POST.copy()
order_items = json.loads(mutable_request_data.pop('order')[0])
print(order_items)
order_details = OrderForm(mutable_request_data)
if order_details.is_valid():
with transaction.atomic():
order_obj = order_details.save()
# create object OrderItem item for each item in the order
for order_item in order_items:
print(order_item)
item = Pizza.objects.get(id=order_item['id'])
params = dict(
order=order_obj,
item=item,
size=order_item['size'],
quantity=order_item['quantity'],
)
OrderItem.objects.create(**params)
else:
user = request.user
form = OrderForm()
if not user.is_anonymous and user.is_authenticated:
form = OrderForm(initial={'phone': user.phone, 'first_name': user.first_name})
return render(request, 'shop/order.html', {'form': form})
def order(request):
form = OrderForm(data=request.POST, initial={
'phone': request.user.phone,
'first_name': request.user.first_name
})
if request.method == 'POST':
mutable_request_data = request.POST.copy()
order_items = json.loads(mutable_request_data.pop('order')[0])
print(order_items)
order_details = OrderForm(mutable_request_data)
print(order_details)
if order_details.is_valid():
with transaction.atomic():
order_obj = order_details.save()
print(order_obj)
# create object OrderItem item for each item in the order
print(order_items)
for order_item in order_items:
print(order_item)
item = Pizza.objects.get(id=order_item['id'])
params = dict(
order=order_obj,
item=item,
size=order_item['size'],
quantity=order_item['quantity'],
)
new_order_object = OrderItem.objects.create(**params)
print(new_order_object)
for key in new_order_object:
print(key)
else:
print('in else')
user = request.user
form = OrderForm()
if not user.is_anonymous and user.is_authenticated:
form = OrderForm(initial={'phone': user.phone, 'first_name': user.first_name})
return render(request, 'shop/order.html', {'form': form})
test these print statements first.
from models import ProductModel - does this work?
frigid egret
Ok, thanks but it was a different thing
I've changed time format recently and i thought maybe it makes form data invalid, do it doesn't get past
if order_details.is_valid():
@remote marsh Thank you 🙂
@native tide can you also post your admin.py?

@frigid egret I don't remember much of Django so sorry if you got confused.
remote marsh
let's hop on to the I hate Django too train 😦 although I haven't been doing much web dev recently.
Evem my live projects are on flask xD [ayushxx7.pythonanywhere.com | mangal-seva.herokuapp.com]
But I'd definitely like to revise it. This channel is helping me move in that direction.
frigid egret
You should follow some tutorial on that. It's really basis stuff and there's alot of material on that online.
@unborn terrace Found the reason why I wasn't using request.user.field. If user is not logged in, It results in errors that AnonymousUser doesn't have that field.

Hi guys. I'm doing web application using graphql (ariadne) + Django. Now I want to integrate it with Facebook authentication without using DRF. So I wanted to use jwt. Is there any good practice or suggestions ? Blog post etc,.. ? In graphql + Django what is your tactic to solve authentication?

What's the best way to document a flask-restful api?
(Asking from not knowing anything about how to document python)
Would I just use sphinx or is there a nice extension so I could use docstrings?
vagrant adder
i would say sphinx is getting bit finiky but since there isn't any other options, i would say go with sphinx

hi, so I was working on a creating a script for printing relevant information to a webpage (zendesk ticket) in form on an html table. The core part of reading information from file and color coding it based on some parameters is done.
However, there are two scenarios that I still need to cover.
- I need to attach/show image present in the logs to the webpage somehow.
- I need to implement a method which can read multiple file names (such as player.log, player.log.1, Android-Dumpstate.log, Android_1-Dumpstate.log etc.)
for attachment, I was thinking of using an html image tag, but then what would be the href part of the image?
for multiple file names, I don't have a definite pathway, I am thinking of using some regex somehow
example of attachment.
see the screenshots uploaded here
I need to do the same, but I need to implement it on my own
as in I want to make it somewhat more easier to code and store
I'll read through this - https://support.zendesk.com/hc/en-us/articles/223137947-Attaching-files-to-tickets-via-API - for the time being

k. my bad looking at the your issue is how to use the api / write a python wrapper for it. and not really webdev...

Are there advantages to using Flask over Django? I'm learning Django currently and am curious about the difference

Hello here
How do you hide elements on Bootstrap based on the support?
Like hiding side bar when switching to smartphone view.
patent cobalt
I have never used Bootstrap, but it probably does something with breakpoints for responsivity and you should be able to use and set those
hard moon
I'm using the latest version.
patent cobalt
I think this page should help: https://v4-alpha.getbootstrap.com/layout/responsive-utilities/
maybe that's not your version, but there should be similar page for your version
I think this section specifically has what you want: https://getbootstrap.com/docs/4.0/utilities/display/#hiding-elements

Ok guys I have a server (software). A computer in my private network which will be the server (hardware). And I rented a domain. Now, the question is, how do I connect these? Currently my domain simply frame-redirects to my actual server ip, but I want the server to use the domain directly! How can I do that?

Can anyone write a dynamic function
which will give the response of API
as a dictionary or text
in short how to consume a API

from client side or server side

Also asking this here as well as OT. I want to make a full stack CRUD web app just to have something to stick on Github. I've done the backend as a pretty neat and simple Flask API, but I can't be fucked in the slightest to actually make a front end. Does anyone have any suggestions for building a not-ugly React app with relatively minimal effort?

can someone help me with my server block so I can have multiple subpaths serving different folders? https://pastebin.com/KnHq5HnF this is my server block for one of my domains, on that same domain im trying to serve a completely different folder /var/www/ualbanylaundrynew/html/ but when i go to domain.com/test it keeps saying not found

@rigid laurel you come up with anything that answers that question? I'll be needing similar soon.

All I really know is that the solution is probably React with Redux - but theres a million different guides almost all of which have problems

Do you want to consume external api or your own
