I run my webpages just using python -m http.server 8080. I guess I could just actually make some server side scripts but it'd be nice if I could have a way to just shove it into the html and just use like eval() since I only will be evaluating my own source code, not user input

Hello. Tried to use retrieve a product by id but Im getting an error.
@app.route('/product/<id>', methods=['GET']) def get_product(id): if id is None or not id.isdigit(): return jsonify({'result' : 'Missing ID!'}), 404 return Product.objects(id=id).first()```
@slow rapids
Try casting it to an int first. As well with mongo you may need a library to help if that's not working either.
So I'm trying to learn web development off a book that works with html, js, and php. The problem being php is dated. Is there a way I can use the
<?>tags but put python in it instead to run server side?
@native tide
PHP was originally just for templates. You can use something such as Django, or Jinja2 with Python. However, it is good practice to keep your logic separated from your templates. This also includes PHP. If you're wanting to really perform calculations and logic on a page look at using JavaScript.

good idea @jade lark I'll probably do django development after I can figure out angular and dbms. Thank you for your input

@warm igloo thank you, can you also use console to write code? as in a import already and things like that?

write code temporarily just to test? use the repl ( https://pythonprogramminglanguage.com/repl/ )
write code in console and save it? use a text based editor like vi
this is all on *nix btw, I have no idea on windows

good idea @jade lark I'll probably do django development after I can figure out angular and dbms. Thank you for your input
@native tide
If you're using Django you'll just need to learn the ORM for dbms.
As well if you're doing simple logic just using plain old javascript would work just as well too. Depending on the size and complexity of your application. I would start with Django first and go from there.
native tide
^^ Handle the backend stuff first and then implement frontend
And React would be good for that 😉
@jade lark really I'm just learning to work with different things first don't have a project in mind. I just want different options at my disposal

@native tide Best way to learn is to pick a project and work on it. Plus finishing something from start to finish is a good way to build a portfolio

@jade lark may i also ask what is the best way to see if a request response is a json? In my case thr request is done inside the endpoint with requests.get(url)

@jade lark may i also ask what is the best way to see if a request response is a json? In my case thr request is done inside the endpoint with

@slow rapids
Check the response headers. Specifically the Content-Type
slow rapids
Yeah i also thought of that but thought there would a way to parse the text and understand if it was @jade lark
Tried googling but didnt find much so i am asking
jade lark
json.loads or json.dumps possibly? You'll need to have exception handling if it tosses a ValueError.
Then checking if a certain key exists or all of them. You could make a helper class or function to validate the data.
slow rapids
Ok thank you for the suggestion
jade lark
You're welcome hopefully it ends up helping.
lunar light
for the requests library, .json() does json.loads for you and it's a bit easier esp. since you don't need to import json
res = requests.get(url)
try:
res.json()
except ValueError:
print("is not json")
else:
print("is json")

Hey everyone 👋 .The question I have today is what do you do to minimise risk that may occur due to human error because you are using an unfamiliar language/ new language As software developers? The only answer I can think of testing and reading from the official documents that is it
warm igloo
If you're new to a language, but familiar with another, try to make sure to apply similar patterns of development. So, if you know good security habits for one language, try the same patterns. Look up the version of the pattern in that new language and it will help you understand the new lang better because you've tied it together by concept.
I've even taken old code I wrote in one lang, and translated it to another. It gave me that bridge of understanding.
And if by risk you mean specifically security risk, you can also minimize risk/errors by using SAST and DAST scanning of your code and running application.
If its a web app, make sure to run it through something like ZAP to test for OWASP top ten.
limpid cave
Thanks for the answer that makes total sense, and I've also learned something new do with security testing

with DRF whenever you want to update the information of an object within a database, would you still use a serializer? I am finding myself just doing it manually when I only want to update 1/2 fields of an object. Is this okay?
stable kite
with DRF whenever you want to update the information of an object within a database, would you still use a serializer? I am finding myself just doing it manually when I only want to update 1/2 fields of an object. Is this okay?
@native tide yes you can use serializers
native tide
And what benefit would that give when you want to just update the fields of an object partially?@stable kite
stable kite
@native tide you can parially update your records through sterilizers in DRF
https://www.django-rest-framework.org/api-guide/serializers/#partial-updates
native tide
I know... but that doesn't really provide any benefit except for running validation and whatnot (all my request validation is done on the frontend too, so that doesn't matter).
stable kite
@native tide wdym i didn't understand your question
native tide
Essentially...
Why should you use serializers VS just using request.data and updating an object?
It's probably just a trivial thought which doesn't matter but I just found myself to not be using serializers, e.g. when deleting objects, or updating a field or two. I would just use request.data
stable kite
@native tide we use sterilizers because they convert json into Model Objects
so that you don't need to do it manually

I don't think you're understanding what I'm asking, it doesn't matter anyways. Thanks

In flask projects do routes go in a different file? Or how is it suppose be structured?

coral raven
what does sqlalchemy.func.coalesce() do?
cosmic aspen
please , in the official django documentations , there is this code
def index(request):
latest_question_list = Question.objects.order_by('-pub_date')[:5]
output = ', '.join([q.question_text for q in latest_question_list])
return HttpResponse(output)
how does this join method works? it's a bit weird , a for loop in the iterable
worthy lake
It is a list comprehension, which is a syntax that produces an iterable. The join method works the same as it does with any iterable.
[q.question_text for q in latest_question_list] is a powerful feature that produces a list called a list comp
worthy lake
l = []
for q in latest_question_list:
l.append(q.question_text)
@cosmic aspen
that is whaat it meaaans
worthy lake
its hands down the most useful thing in python imo
cosmic aspen
yeah , i literally said to myself "Who's the genius behind this sorcery"
worthy lake
theyre even more powerful than that. You can include conditionals in there as well
l = [q.question_text for q in latest_question_list if q.pk % 2 == 0]
You can do list comps inside of list comps, if your iterable is also a list comp. There are also dict comps
worthy lake
Its kind of a breakthrough in assembling the data you need when you realize its a thing
limber laurel
How could I practice/learn deployment?
bronze blaze
you can create web apps and deploy them on Heroku
limber laurel
Alright
worthy lake
In addition to heroku, you can also spin up VM servers locally if you have a computer that can handle thata. It wont allow you to easily put the sites online, but... it will teach you to configure a production server with all the things needed for it to work.
And... you can use it as a local network server more easily at that point.
warm igloo
Deployment is a LARGE term
to a VM?
to baremetal?
to kubernetes?
to swarm?
then, dev, staging, or prod?
do you want to do pipelines with ci/cd, do you want to sftp files, do you want to rsync them?
worthy lake
yeah thats true. They start to call it DevOps at that level of sophistication.
But you got to start with just pushing to a server that either is in production or works the same as one that actually is.
I find rsync to be pretty awesome when working with local VMs
Thats really the only experience i have with devops other than heroku
warm igloo
if you do end up wanting to do local vms, check out proxmox or even just virtualbox
worthy lake
yeah virtualbox is what i use
warm igloo
should be building a proxmox cluster across 6 thinkcenter mini-pcs soon
warm igloo
it's a open source competitor to VMWare/ESXi
worthy lake
Mine are mostly test servers. Ah okay.
warm igloo
so legit vm operating system with all the things you could want
worthy lake
is virtualbox not a fully featured hypervisor?
warm igloo
monitor all your vms, freeze them, copy them, etc
worthy lake
virtualbox is all i know
warm igloo
virtualbox has limitations AND it runs ontop of your OS where ESXi or proxmox ARE the OS
so closer to the metal
worthy lake
I see.
warm igloo
check it out sometime if you want to grow your skills in that dept (managing vms) as you get way more control over the vms, the resources they use, their volumes, etc and is closer to what you'd use professionally
worthy lake
Cool, Ill check it out. My major issue with VMware was that it was proprietary and not accessible when i tried it.
So ill do that next time i need to
warm igloo
they do have a free version you can use to learn, but there are some limitations, but in the homelab world most people recommend proxmox as it is open source and you'll learn the same things
Also, if you don't know about the homelab hobby like I didn't earlier this year .. checkout out r/homelab on reddit sometime. And good luck to your wallet/free time. Haha. 😉
thankfully I got free hardware from work to do some stuff like those 6 thinkcenter pcs, but I've also created a kubernetes 5 node cluster on raspberry pi 4s using a laser cut blade-server chassis.
And now we're not talking about web development so I'll stop
worthy lake
yeah, unfortunately, I dont have the money to run a home server room haha. I like the idea but it seems unrealistic for me.
worthy lake
Is there a way to change path('accounts/', include('django.contrib.auth.urls')), to a different end point when using those generic auth views? For example, I can change that to path('users/', .... but, this doesnt change the fact thaat all the other views loaded in by that include still use 'accounts/'
This is described here https://www.webforefront.com/django/setupdjangousercreation.html
For now im just going to leave it. I can learn more by not changing things constantly, but I still would like to know.
ah, the way you do it is right there. You just explicity call all of the views insteada of using include

Is there a way where i can display live database modifications on django without reloading the wrbsite?
swift heron
@native tide so is a header what is used to specify the function you want to run?
halcyon lion
anyone knowledgeable on django/html wanna hop on a voice call. I need some help on how to setup a search funcion 😦
native tide
@swift heron no... why do you have a function inside a function anyway? Can't you just seperate the endpoints?
Headers are just part of the request
But in your request you can send JSON
swift heron
yeah I was just going by an example on stackoverflow I didnt understand it either but this is all new territory
swift heron
yeah Jquery
native tide
So in your request, you can include JSON. Such as {test: true} then in your function, you can see whether test is true (therefore running the 2nd function) or if it's false not running the 2nd function.
It would probably be easier if both of the functions were part of a class, too
@hybrid patio What's the issue?
@halcyon lion Best to do that with JS, I'd recommend React and having some backend APIs
halcyon lion
@native tide i am dumb
just had the form name wrong in my view
and it works fine now :d
it says results in bulgarian 😄
swift heron
okay I think I have an idea of what is happening let me try this one second
native tide
Also, what is the point of the view in the first place? You're making a POST request to a regular view, not an API endpoint. Am I missing something?
swift heron
so here is what I am thinking
$.ajax({
url: '127.0.0.1:8000/computer',
type: 'POST',
json: {test: true}
});
Which when somebody goes to 127.0.0.1:8000/computer
A requrest will be sent to my views function to load that page
def computerView(request):
context = {'title': 'Computer Stream', 'applications': computerStream.applications}
if request['true']:
print("Fired!")
return render(request, 'pages/computer_view.html', context)
But I am checking the request json if the value is true and that is how I communicate from the frontend to the backend?
This example dosent work but is this the general idea?
I am trying to run a function is all
native tide
Yes that's the general idea. But it will have to be within an API endpoint, not a regular view.
Also it would be if request.data["test"] == true: in Django
swift heron
can you show an example of an API endpoint?
swift heron
nope havent seen this yet
native tide
That'll be essential for you to learn if you want to start implementing communication between a seperate frontend and your Django backend
swift heron
Alright great ill get started on it then
native tide
An example API endpoint is similar to a view, they vary, this is a function based view:
@api_view(["POST]) # means this function only handles POST requests
def example_view(request):
if request.data["true"] == 1:
print("fired!")
okay thanks im going to research this more and ill give it a shot you have been a great help thanks!

I've just got a new machine, installed VS Code, Installed Node JS, messed with the settings since the bloody thing couldn't find the python .exe file, got that to work and finally got to the point where I can install django
Problem is, when I activate pipenv (pipenv shell) I don't see that the environment is activated like (environment_name)User@USER in my terminal
I'm attempting to take all the jQuery off of the django install and use VUE instead, in order to do that I needed to do some bollocks npm install vue or whatever
prisma jackal
I have models.TextField() in my model but I want that only few characters to be seen in my browser, how can I achieve that? Django
swift heron
@native tide so reading through this documentation and watching videos it seems we are taking the data and putting it into a model (fancy class) and from there we serialize that data to a database? from this point our frontend can get/post data to that database and our backend can work with the database? is that the basic idea or am I spitting out nonsense?

I’m trying to make a server that serves a static html file using django.
Is there any way I can just send that file without dealing with templates and stuff?
dapper tusk
you could host it as a static file, similar to an image, and send it from the view using whitenoise.
don't think the builtin staticfiles can serve in deployment

I am working with flask jwt extended and have a login route that looks like this:
@app.route('/Login', methods=['POST'])
def login():
try:
user = get_user_from_db(request.json['email'])
password_correct = check_password_match(request.json['password'], user.password)
if password_correct:
access_token = create_access_token(identity=request.json['email'])
refresh_token = create_refresh_token(identity=request.json['email'])
resp = jsonify({'login': True})
set_access_cookies(resp, access_token)
set_refresh_cookies(resp, refresh_token)
return resp, 200
and a refresh route that looks like this:
@app.route('/refresh', methods=['POST'])
@jwt_refresh_token_required
def refresh():
current_user = get_jwt_identity()
return jsonify(access_token_cookie=create_access_token(identity=current_user)), 200
But, I get a Missing CSRF token message
app.config['SECRET_KEY'] = os.getenv('JWT_KEY')
app.config['JWT_TOKEN_LOCATION'] = ['cookies']
app.config['JWT_COOKIE_CSRF_PROTECT'] = True
app.config['JWT_CSRF_IN_COOKIES'] = True
app.config['JWT_ACCESS_TOKEN_EXPIRES'] = timedelta(seconds=10)
I set my CSRF in cookies true
I checked my cookies to make sure they exist

Anyone know a library for working with microsoft's oauth2
native tide
@swift heron that's correct!
Serializers translate the request data (from JSON to Python), which can then be saved to represent an object in the database.
A ModelSerializer serializer tries to replicate the model that it is linked to. I'd recommend using that.
swift heron
okay great, just working on having jquery grab that data now but I havent looked to much into it yet
shell heath
@night atlas There are good resources online. Just follow the tutorials for a couple of projects and you will be good to go. I actually prefer books, but the content can be daunting. So tutorials is a good way to go about it. Deciding on which library you want to learn is a harder task. I started from tkinter and moved on to pygame. There's pyqt5, wxpython and many more. Also, try out your own projects once you finish the tutorials. This will be the fun part!
sonic cedar
@shell heath Do you know about python turtle ?
shell heath
I haven't used it explicitly, but I know it.
@sonic cedar But haven't touched turtle since I learnt pygame.
sonic cedar
@shell heathCan I speak with you in private?
shell heath
@sonic cedar Sure
night atlas
@shell heath so what should i mastering first? the GUI one or the basic one first
shy finch
any python web developer here? I need to ask some question...
not about coding, pls dm me if there is a Python web dev
jovial fractal
shell heath
@night atlas If you know basics of coding, you can jump to gui to solidify your fundamentals. If not go over the begginer tutorials and try to master the basics first. Python Crash Course is an excellent book to start with basics and small scale projects
shy finch
can anyone help me with a question?
shy finch
Q: I want to learn pyhton web develeopement, so do i need to learn HTML, CSS, JAVA for web design?
shell heath
I'm not a web developer by any means, but I learnt a bit of html and css before jumping into django. So yea, knowledge is never harmful
shy finch
Yeah i know html css
but do i need to learn it advanced?
or when i work someone will do that for me?
placid vale
Q: I want to learn pyhton web develeopement, so do i need to learn HTML, CSS, JAVA for web design?
@shy finch yeah if u want to work in frontend
but do i need to learn it advanced?
@shy finch or if u dont want learn advance u can learn there frameworks like bootstrap

Does anyone knows about django querys? I know that this one is easy but I'm so bad at it 😦 https://stackoverflow.com/questions/64861260/query-in-query-in-django/64861969#64861969
native tide
@swift heron Idk how it is with Jquery, but making requests from JS is really simple with axios and it's promise-based.
@primal kernel It looks like you're going to need to connect your models, right? Possibly set up a one-to-many relationship between "Courses" and your other models so you can access them directly.
primal kernel
They are connected, every consumption is related with a client and a course
native tide
@prisma jackal you can set a max-length to the textfield
Oh I see
So your course only has one field, its name, what attribute determines the number of courses sold?
primal kernel
Every consumption has a course associated, what I want is get the best selling courses, like: Course 1 1020 sold, Course 2 992 sold and so on
Like 1020 consumptions has that course associated
I think I could do it in 2 steps but I dont think that's the most elegant way to do it
native tide
Is "Consumptions" the orders of the course?
primal kernel
yeah
native tide
Could you do: (just paraphrasing)
courses = Consumption.objects.filter(course) # This gets you the list of courses
# Loop through the courses and sort by 10 most occuring.```
hybrid patio
FLASK ?? someone to help me ??
native tide
You could setup a "amount_sold" or similar in the course model
and that would make it much easier
@hybrid patio Ask the question instead of asking to ask
hybrid patio
ok but I have problem with templates
primal kernel
Yeah I could do that, i could get what I want in 2 steps
But thats not the best way
primal kernel
Anyway @native tide thank you so much for helping me, I think that I will do it in 2 stems till I get the knowledge to do it in a different way

article file
native tide
Yeah looping through the queryset isn't a good option, but ideally you would add a new column to the 'Course' model such as orders , and you can use decorators such as @post_save to increase the orders every time a Consumption is added. Then you can simply and quickly sort it.@primal kernel
Or add the order_numer to the Consumptions model and do the same.

@native tide i am learning Django so it popped in my mind

why article?
native tide
Because if you looked at your error... it literally says value is undefined
You are not passing a value to your HTML page, you are passing article
hybrid patio
I know
native tide
def article(art_id):
article = articless[art_id]
return render_template("article.html", article=article)```Look at the render_template, you are passing article=article to the HTML page
hybrid patio
ah 😄
native tide
and article is in the form {"title": x, "content":y}

ok than you so much

static harbor
How can I serializers (using django rest api) two models like
class A(models.Model):
name=Textfiled()
class B(models.Model):
book=Textfield()
name=Foreignkey(A)
startDate=Datetime()
endDate=Datetime()
this, so that I can create an api which gives json response like
{
"name":"tet",
"books":[
{
"book":"test",
"startDate":"2020-12-6",
"endDate":null
}
]
}
I want to understand how can I write serializers for these two models?

Guys, sorry if I'm wrong category in case you notify me and change.
I need to be able to assign this underlined value to a variable. However, this "content" text changes with each link, so the program must be able to fetch it every time

@static harbor You can use DRF's modelSerializer
I'd recommend looking at the docs for that module

.nav a {
display: inline-block;
padding: 10px;
text-decoration: none;
}
footer {
text-align: center;
}
I need use something for this
but what is .nav??
native tide
using . represents a class name

If in the HTML I had a div with class example, in the CSS doing .example would target that div

round wave
can session variables be changed from the client? So when i save a email or something to save the account a user logged in, can i be sure he can't change that?
round wave
then just ask the question and dont just say that you have one?
hybrid patio
ok without answer
native tide
I want to know that I can watch the web as much as I want through Python
just..not seing
@hybrid patio Yes you can. Go on W3 to get a rundown of how CSS works
native tide
@round wave If the session ID is stored in the cookie, yes. They can change it.
umm..
round wave
so whats the best way to save in what account a player is logged in?
maybe save a hash of the password too?
native tide
save a list?
@round wave save a hash of the password where? as a cookie?
Session auth will work fine. If the user changes the session token to one that does not match with the account, they should be logged out.
round wave
im new with web developement, so can i just save the email now?
native tide
wdym by save the email?
if you're using Django and don't have a seperate frontend use session auth, it'll do it all for you
round wave
im using flask
native tide
Well flask should have a library which solves that for you
round wave
do you know the name?

A simple google search would get it for you. I haven't used Flask in some time
If you follow a signup/login tutorial for flask they'll probably cover it too

Hey I am trying to setup Django REST Serialization, but for some reason the page is not found
Like a url that starts with api is is not recognized

# REST Framework URLS
path('api/plan/', include('users.api.urls', 'plans_api'))
]
users/urls.py
app_name = 'users'
urlpatterns = [
path('<slug>', api_detail_plan_view, name='detail')
]
I have found my mistake, I needed to use users prefix as in my main app the prefix for users is users
In what case would I use serialization?
and api views

what is the recommended fastest way to get the output of a python script displayed on a webpage? i am building an app that will only ever be run locally but i would like some qol UX features and figured a webpage would be the most convenient way. django seems like overkill and im unable to find a flask tutorial that simply outlines how to achieve my goal?
like, i just want to turn a python dict into some text on a webpage
grizzled meteor
well, you prob def want to use Flask
and Django is 100% overkill
what are you using for your Front-End @native tide
native tide
im fine using basic html/css for now
it's just a series of scripts that im running locally for myself
any framework seems like overkill tbh. i feel like im better off just exporting to csv or something else if i don't want to stare at the cli all day
also ty for the response
grizzled meteor
i mean; tahts True lol
but at least with Flask, you could just configure a simple end-point and have your Front-end smack that endpoint for the data
native tide
yeah
grizzled meteor
up to you; can be tackled all kinds of diff ways and you prob don't need a web-framework to do it
native tide
im functionally new to python so i feel like it's just too much to learn at once. i'd rather just focus on getting my scripts to do what i want rather than take on a web framework
yeah
thank you

@topaz widget I've had that problem too, but I sadly don't know a solution
chrome onyx
You could do some complex styling to the dictionary to get it in a table and etc., just remember that anything inside {{here}} is a reference to Python, so you can use Python code in there.
For example: {{dict["What is this?"]}} will just display A dictionary
native tide
that's perfect

More complex templating syntax (such as for loops and if statements - within your HTML code) are available... check out jinja2 if you want to learn more

{% if owner.userid == user.id or user.staff == True %}
This is what im doing and the current user is not the owner but is staff, but what its supposed to do when staff is true, is not happening
pulsar hinge
Why don't u just put {% if user.staff %}, i suppose owner is staff as well.
@verbal snow
pulsar hinge
than instead doing {% if owner.userid == user.id or ... %} do {% if user.id == owner.userid or ... %}

Didn't change anything
It's like django can't parse anything
It'll parse half the statement in some cases

In Django, why should I make a custom user model inheriting from AbstractUser? why cant i just get it from the AUTH_USER_MODEL thing? (im not 100% sure about the names here)
There should be one obvious way to do things, and inheriting from abstractuser to make your own custom one does not make a lot of sense to me.
I would love some insight into this?
for the record, I am using AbstractUser in my custom user model, but I wonder why.
native tide
@sturdy sapphire Iirc AUTH_USER_MODEL (by default is django.contrib.auth.models.User) has it's own attributes and methods such as is_authenticated, which other parts of Django will leverage. So, if you create your own model overriding this, some parts of Django won't work with your model (such as authentication).
https://docs.djangoproject.com/en/3.1/ref/contrib/auth/
So by inheriting from AbstractUser you keep all of the attributes / methods of Django's User model, and you essentially just add some custom data fields.
sturdy sapphire
right, that makes sense. thanks @native tide
native tide
@verbal snow You said that the user is staff? So this will always run as it's truthy
{% if owner.userid == user.id or user.staff == True %}
right?

@swift heron your endpoint can return a Response, you'll have to import it, can't remember off the top off my head
And that will return JS which your frontend can handle
swift heron
alright awesome will look into it, thanks again!
native tide
Also import status (which returns the status of the request back to the frontend, such as 200 (OK) or 404 (not found)
An example would be this for your API endpoint
# import Response, status
def example_endpoint(request):
# do something with the request
data = {"success": "request was successful"} # the data you want to return to your frontend
return Response(data=data, status=status.200_OK) # specify data=<data you want to return> and status=<status you want to return>
Then in your frontend you can access the returned data
verbal snow
I'm using the erorr page example on the django site
def response_error_handler(request, exception=None):
return HttpResponse('Error handler content', status=404)
def permission_denied_view(request):
raise PermissionDenied
handler404 = response_error_handler
``` but it still renders the regular oneI'd recommend axios for the requests
swift heron
Alright thanks Ill be trying that out after a short break 👍

Currently at the moment on django I am using generic class based views to CRUD my tables from the database. If I want to view them all on a homepage, should I still use class based views for that?
Currently using list view to view info
Maybe switch to FBV for what I’m trying to do

Hi, I'm a total newb. I have a server that I'm renting. I'm looking for a tutorial on how to use python on my server to do things like respond to a POST request
The simpler the better. I'm only trying to do the most basic things.
topaz widget
@half vale Use a framework like Flask.
Django works, too, but is typically for more complicated stuff.
Flask is easier to get started with from what I understand.
indigo kettle
@visual lake it is a sibling, are you sure that the class indexName is used only once on that page though? You might be getting a different element on accident
visual lake
yea you're right the first one on the page actually doesn't have a sibling @indigo kettle
indigo kettle
so you'll have to find a different way to access that element, maybe first finding a parent and then finding that class name afterwards
visual lake
I can get to "DJ Italy" which is a child of indexName which inturn is a sibling of indexValue
would that work?
nevermind, thanks for the help @indigo kettle
indigo kettle
oop, sorry. Np!
half vale
@topaz widget I don't really understand how to use Flask on a remote server. Do you know a good place for me to learn?
topaz widget
Learn on your local computer. I think Flask probably has a built-in local server. When you feel comfortable with your app, then transfer it over to your remote server and configure the server to run your Flask app. @half vale
half vale
I already understand how to program from my local computer. I'm looking for resources on how to do it remotely.
topaz widget
Corey Schafer has some tutorials on YouTube for Django. He might have some on deployment for Flask, too. I know he has Flask tutorials, just not sure if they cover deployment.
Do you have some server software like Apache or NGINX installed? You'll probably need that too unless you're using some pre-configured solution.
half vale
I have a server up and running. There's a terminal I can get to from cpanel. That's pretty much all I know.
I published a sample site and then replaced it with my own html and js files. But I don't know how to code actual server side code.
I will check out Corey Schafer.
topaz widget
Yeah, getting a server set up properly can be somewhat involved, but for simple stuff, there are ways to make it easier like Heroku. I'd recommend looking at Corey Schafer first. He's pretty good at explaining things that can be somewhat complicated.
half vale
I like the host that I have I just don't understand how to set up a server honestly. Or how to change one that's already been set up.
topaz widget

Thank you.

I haven't used sqlalchemy but have used django often
I can try to help. Is it important to have referred_by and referred_to fields?
is the referred_to, not somehow related to referred_by
I think I understand
I think the issue is that you have multiple backrefs with the same name to the same model
dest_address = db.relationship('Address', backref='orders', lazy='select')
from_address = db.relationship('Address', backref='orders', lazy='select')
status = db.Column(db.String(MaxLengths.order_status), nullable=False, default="Pending")
products = db.relationship('Product', backref='orders', lazy='select')
subtotal = db.Column(db.Float(), nullable=False)
shipping_fee = db.Column(db.Float(), nullable=False)
tax_cost = db.Column(db.Float(), nullable=False)
total = db.Column(db.Float(), nullable=False)
discount_code = db.relationship('DiscountCode', backref='orders', uselist=False, lazy='select')
here you have 3 backref='orders'
I think these will have to be unique or else there will be no way to access them
actually, the discountcode should be fine
but the other two are both coming from Address
so those will have to be unique
you also have 2 reviews fields on the Product model
I'm not sure exactly how this works but for the referred_by thing I was asking about, I think this is the right time to use backref because referred_to, and referred_by should be kinds of mirrors of eachother
referred_by = db.relationship('User', backref='referred_to')
idk exactly how it should be written
just a thought
did you run a migration?
one of my first large web apps I wrote was an ecommerce app so this all looks very familiar
fun stuff!
another thing, here on Product
ordered_by = db.relationship('User', backref='product', lazy='select')
orders = db.relationship('Orders', backref='product', lazy='select')
you have ordered_by as a field, but users has a relation on the order, so you can access users through the order model
hm, I feel like it should be accessible without writing it again like this. But I don't know exactly what sqlalchemy is doing so I'm probably wrong
haha
yeah, you'll bang your head against a wall for a while before it all makes sense

I am trying to create a Flask application, however, my extend title isn't working. It was working in a different IDE, but I cannot use that one anymore.

native tide
It also appears that all other blocks do not work too
topaz widget
@native tide It's not obvious from what you posted what the problem is, and as bri said, changing your IDE shouldn't make any difference unless it's a tabs vs. spaces issue in your Python code. This does not seem like a Python issue, though.

Hey guys after deploying my django website how is it possible to access my django admin ui?
@unborn mural Go to the/adminurl and enter your superuser credentials. If you have not created a superuser, the command to create one should bepython3 manage.py createsuperuserfrom the root directory of your Django site (the directory with yourmanage.pyfile in it).
unborn mural
no nooo
tht one is okayy
but like let's say i create a simple blog application
and then deploy it
topaz widget
Same deal
unborn mural
if i need tp create , edit or delete my db
then how do i access my admin of already deployed website
topaz widget
There are a number of commands to interact with your db.
I'm not exactly sure what you're trying to do.
unborn mural
I'm not exactly sure what you're trying to do.
@topaz widget bro there's this django admin ui ryt
how do i access tht after i deploy my website
topaz widget
are you talking about the admin page?
unborn mural
yes
unborn mural
Should be the same url
@topaz widget then anyone would be able to access it ryt
topaz widget
If they can guess your credentials, yes.
Django recommends changing the admin login page url to something only you know.
You can do that in your root url conf if you think you need the security.
(urls.py)
topaz widget
The default url is admin/
@unborn mural Make sure you register all your models in your admin page, too. Should be done in something like an admin.py file in each app.
unborn mural
yess okay

Any ideas why this error?
django.db.utils.OperationalError: (-1, 'MySQL Connection not available.', None)
I'm using mysql-connector-python and a remote DB
Oh btw, this happens when I try to create a super user only
gaunt marlin
@tranquil idol https://www.w3schools.com/js/DEFAULT.asp
@rapid bramble you said you have remote DB right? can you connect to the database? the error probably from timeout timer exceed when connect to the DB
try running in shell with python manage.py shell
and
import django
print(django.db.connection.ensure_connection())
if it return None then the connection is ok, else it will print out the error
rapid bramble
I'm able to connect to the database remotely yes, and that is pretty obvious considering that error occurs only during super user creation and rest of the connections - login signup and other stuff involving dB is fine.
But I'll try the second portion of it when I'm back on the PC.
Also, it occurs randomly, like if I set CONN_MAX_AGE to 36000 sometimes it works and sometimes it doesn't
Pretty weird

@native tide your code will be stored in both github and the heroku server in order to run, you would also need to set up your database on the server though
limber laurel
What woild be the use case if serialization?
native tide
@limber laurel Can you elaborate
limber laurel
Like when would I serialize a view and return it in a json format?
native tide
When you want to return data to your frontend
limber laurel
But like why would I want to do it that way?
native tide
Let's say that you make a request to your API endpoint with JSON and want to save it to your model... You can serialize it and then save the serialized data. That has advantages because you can add custom serializer validation (which is different to your model).
But if you want to just return some data, serializers just validate that the input is what is expected. For such views I usually don't use serializers (as all of my input validation is on the frontend anyway).

does anyone know how to make css work in django
i mean its working but when i save the page changes arent reflected after refresh
it only works when i restart the server
it worked initially but now it doesnt
sometimes it works sometimes doesnt
rapid bramble
@green snow Ctrl + F5
If you check Django development server logs you'll see a 304 on the CSS file, which basically means that the CSS file has been cached by the browser and the latest copy isn't being fetched.

native monolith
can someone explain render and super() ? last sentece
empty pivot
@native monolith rendering is what the computer does when it decides what to display to the user and then displays that. super refers to the class which a certain class inherits or extends.
So if I have an Animal class then a Dog class which inherits properties and functions from Animal class, then I can use super in the Dog class to refer to properties or functions from the Animal class.
I think I got that right :)
native monolith
in know python super, but is this the same in flask and html?
slender moat
yes, but that's not html, it's a jinja2 template
native monolith
ok, but written in html 😄
slender moat
render in this context pretty much means that it will copy and paste some content
in the place where you called super()
native monolith
hmmm
so it copies block head from parent and extend it ?
I see
thanks @slender moat
native monolith
could you also give me short desc what is the difference? {% %} {{ }}
what I understand is that {% %} refers to conetxt, and {{ }} is code
or {%%} is escape for jina, and the other i do not know 😄
slender moat
just check the docs
{{ }} are expressions and have some kind of output
{%..%} are statements and have no output

Hey, I want to preload some data on one of my webpages, I dont want to use a dataframe however because that slows down the server a lot if their is traffic.
I was wondering, if a dictionary of dataframes solves the above?
instead of one giant DF, allow for a dictionary of an estimated 900 Dataframes?
rustic pebble
If one dataframe slows down your server how would 900 dataframes make it faster? @glass badger
glass badger
The differences is the dataframe would be parsed, and if a user wanted to look for an item located in my dataframe, they wouldnt have to look through 100,000 rows
Instead they would locate the key index
making it much faster
inland stirrup
I said this yesterday and someone replied with "this shouldn't be a python issue" Any idea what is messing up? Maybe like a Flask setting or something? It seems as if Jinja is just reading the first line and not reading the rest
@native tide technically this should work ...is your file structure proper
native tide
What do you mean by that?
rustic pebble
The differences is the dataframe would be parsed, and if a user wanted to look for an item located in my dataframe, they wouldnt have to look through 100,000 rows
@glass badger I am not sure what you mean
If that's the case why not have a local db with all the dataframes and then just a route that the user can make requests to
That would be the fastest
inland stirrup
i mean all the html files should be in templates folder and all other python files should be in a level above the template directory @native tide
glass badger
@rustic pebble to my understanding, doing a "look-up" on multiple rows is always much more extensive then not having to look through rows if they dont have too
Play with a dictionary of dataframes and you will see what i mean in terms of speed. However I don't know about the RAM issues with a dictionary
which is why I ask 🙂
native tide
That is what they are at. https://xenophoxic.is-a-virg.in/3c9Jzc
I think that is what you mean

@rustic pebble I have a dB that I write queries too, not sure if thats what you meant.
rustic pebble
You can load the dict you are talking about in the server memory, assign a unique id to each one of them or something to identify them and then you can create a route like this:
@app.route('/get-df/<df_id>', methods=['GET'])
def get_df(df_id):
return {'data': dataframe_dict[df_id]}

Yes I do, thank you for the example. So would the server calls be made client side?
@rustic pebble
rustic pebble
Yup, a really simple fetch api
This method would really make your load times faster since all you would need to do is get the keys
glass badger
I have a question, would this be a similar networking to a rest api?
rustic pebble
So you would have something like this:
@app.route('/')
def home():
return render_template('index.html', dataframe_keys=dataframe_dict.keys())
Now you would have to iterate through the dataframe_keys list to fill the frontend using Jinja2 server-side rendering. Now if you want to make a client-side request you can do the following:
async function get_dataframe_data(dataframe_id){
let url = "/get-df" + dataframe_id;
const resp = await fetch(url, {method: 'GET'});
const dataframe = await resp.json().data //or await resp.json()['data'] JSON can be accessed either as an object or as a dict
return dataframe
@glass badger
I have a question, would this be a similar networking to a rest api?
@glass badger Yes
glass badger
@rustic pebble ohhh okay I see now, thank you so much!
rustic pebble
No problem!

Hello
So I have a django rest api
and a reactjs app which consumes it
so I want to access the authenticated user's info from the reactjs frontend
whats the best way to do this?
Right now I have an api view like this to access it is this right?
class CurrentUserView(APIView):
"""
An APIView to get the current user
[authenticated user]
"""
permission_classes = [permissions.IsAuthenticated]
def get(self, request):
user = request.user
serializer = CurrentUserSerializer(user)
return Response(data=serializer.data)
seems fine to me
twilit needle
is this how its generally done
native tide
how do i read static files
twilit needle
okay if theres any other better practice
someone pls tell me I have no idea
thanks @indigo kettle
indigo kettle
yeah if someone else is more familiar hopefully they can answer, seems perfectly good to me though!
safe oasis
@naive oar Is there any way I can do this with requests? Because there is a thing called
requests.Session()
But no idea on how to get its id
naive oar
@safe oasis I'm sorry not sure about getting the session id?

guys what should i start to learn, flask or django?
twilit needle
this is not a hiring place sorry
@peak locust
guys what should i start to learn, flask or django?
@wet heath Django
I have a doubt with Django.
So my media files are saved in a directory called media
here's my settings.py
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
I want to display my files on the website, like
If theres a file with the path /media/images/default.jpg
then when I go to my_url/media/images/default.jpg The image should be displayed on the browser
how can I do this?
discord does the same thing, but how?
like this url
https://media.discordapp.net/attachments/755747397610504322/766515746653208596/repo-icon.gif
see?

I added some enum types in flask, but when I update the object, it says this enum type was not found
is editing enums not possible in flask sqlalchemy?
native tide
@twilit needle What authentication method are you using
You shouldn't be serializing request.user. You should be serializing request.data which contains an Authorization header with your user token.
Which (on sign up / login) you should be sending a token to your frontend which then saves it as a cookie.
@merry kelp on page A have a link to page B. On page B have a link to page C.
prisma jackal
I want to implement reddit upvote/downvote blog post but I don't want to reinvent the wheel. I need a help, I use django.
plucky tapir
Really quick question. Is there a way to define a column in a models thatll take in a number and make it negative?
native tide
@prisma jackal just add an 'upvote' field to your model and handle the rest on the frontend.
@plucky tapir wdym by that
stone wren
@prisma jackal just add an 'upvote' field to your model and handle the rest on the frontend.
@native tide that and I would recommend running your view asynchronously
native tide
how could you do that? make it AJAX?
twilit needle
@twilit needle What authentication method are you using
@native tide hello
How can I make this possible
any ideas
native tide
Make what possible again?
twilit needle
sending the data and saving it as a cookie
stone wren
how could you do that? make it AJAX?
@native tide both platforms
frontend and backend
native tide
@stone wren Oh yea I gotchu. Frequent API requests from the frontend to update the counter async
@twilit needle So... do you have a separate frontend, or are you just using Django templates?
Wait that doesn't matter
twilit needle
import SideBar from './components/anchored/sideBar';
import './staticFiles/css/app.css';
import React from 'react';
import axios from 'axios';
import api_url from './configuration.js';
import RegistrationForm from './components/forms/authenticationForms';
class App extends React.Component {
constructor(){
super();
this.state = {
loggedIn: false,
user: {}
};
this.handleLogin = this.handleLogin.bind(this)
}
checkLoginStatus() {
axios.get({api_url}+'users/current-user/', {withCredentials: true})
.then(response =>{
if (this.state.loggedIn === false) {
this.setState({
loggedIn: true,
user: response.data.user
})
}
})
.catch(error => {
if (error.response.status === (403 || 401) && this.state.loggedIn === true) {
this.setState({
loggedIn: false
/*the api raises an 403 NotAuthenticated error when trying to
fetch current-user data as an anonymous user */
});
} else {
console.log(error);
}
})
}
handleLogin(data) {
this.setState(
{loggedIn: true,
user: data.user}
);
}
componentDidMount() {
this.checkLoginStatus();
}
render() {
if (this.state.loggedIn === true) {
return (
<div className="app-container">
<div className="app-mount">
</div>
<SideBar />
</div>
);
} else {
return <RegistrationForm />
// bring up authentication container
}
}
}
export default App;
So this is what I am doing right now for the app.
I make a api get request for the current-user data and then if the api responds with an error [which means user isnt authenticated] then I bring up a login container
native tide
Nice, React, I like it
twilit needle
I am using reactjs for frontend
native tide
Okay, so what authentication method are you using?
twilit needle
idk sorry whats that
native tide
For example, session authentication or token authentication
In Django you have to specify your authentication method, and isAuthenticated checks against that.
twilit needle
So this is what I am doing right now for the app.
I make a api get request for the current-user data and then if the api responds with an error [which means user isnt authenticated] then I bring up a login container
@twilit needle is this best practice? like checking all those stuff, bringing up a login container and then after login deleting the container and finally bringing the app cointainer?
Ohh
is it in settings.py
native tide
Yeah, it's covered in Django authentication docs.
twilit needle
okay
native tide
For a React frontend I'd recommend token auth
twilit needle
class CurrentUserView(APIView):
"""
An APIView to get the current user
[authenticated user]
"""
permission_classes = [permissions.IsAuthenticated]
def get(self, request):
serializer = CurrentUserSerializer(request.data)
return Response(data=serializer.data)```So setup that authentication, and whenever a user is added to your database, give them a token.
twilit needle
is this what I should do?
earlier I had this ```py
class CurrentUserView(APIView):
"""
An APIView to get the current user
[authenticated user]
"""
permission_classes = [permissions.IsAuthenticated]
def get(self, request):
user = request.user
serializer = CurrentUserSerializer(user)
return Response(data=serializer.data)```
Yep
twilit needle
okay
is this best practice
do you recommend doing this
something seems wrong to me thats why I am not used to this type of coding
how do I setup authentication? can u pls link the docs
and @native tide should I implement the auth for the whole project or only specific api views
native tide
When you set the authentication method in settings.py, it is the default auth for every view which has the isAuthenticated permission (which can also be set as a default).
So you're setting it for the whole entire project
And if you want views without any auth, you can use a different decorator (forgot what it is, it's in the docs)
twilit needle
yeah I get it now thanks
omg my project will be so insecure if u didnt tell me this thanks
one sec il finish auth then what should I do
native tide
Have a look through Django auth docs. (or maybe it's DRF, can't remember) then ask any questions if you have any
I'll be back later and I can help you with the React stuff
but I got a lesson to go to
twilit needle
okay thanks
one last thing
so the token you told me, thats where Ill store my user object right
native tide
I don't understand the question
Each user in the database will have a token field associated with it
twilit needle
okay
class CustomAuthToken(ObtainAuthToken):
def post(self, request, *args, **kwargs):
serializer = self.serializer_class(data=request.data,
context={'request': request})
serializer.is_valid(raise_exception=True)
user = serializer.validated_data['user']
token, created = Token.objects.get_or_create(user=user)
return Response({
'token': token.key,
'user_id': user.pk,
'email': user.email
})```
like this custom one what should my token haveso when you make a request to the API, it will have the token in the header, so the backend can know which user it is (from request.user which it handles)
