I'm looking at someone else's code for a flask app and trying to learn some basic stuff with it. I don't quite understand what's going on with this in a template and how it's 'seeing' these variables despite not being passed in the render_template() method
<div class="w3-container">
<p>
{% if config.lang == 'fr' %}
Pour commencer un test, utilisez le lien d'activation
que vous avez reรงu.
{% else %}
You need an activation link to start a quiz.
{% endif %}
</p>
There are context processors
limber orchid
config is app.config, I've seen that much but...
outer lynx
Context processors can give global context to templates
limber orchid
so if I make a variable of my own in my app how can I turn it into one of these global type things?
outer lynx
@app.context_processor
def _():
return {'global': 'hello'}```where context_processor is the name of the variable?
limber orchid
I'm looking for it in the py file and don't see anything named like that
outer lynx
@app.context_processor
def _():
return {
'global_var_1': 'val_1',
'global_var_2': 'val_2',
'global_var_3': 'val_3',
}```This can be anywhere
But config is by default
config session request url_for are just a couple of them
limber orchid
thanks, I'll keep digging
I just can't find where they hid this dictionary
or is it possible to set a new entry inside the app?
like, all I'm seeing is things being initialized like
app.config['key'] = 'thing'
do I need to go into the config to create first 'key' entry or will it let me set it like this?
ok nm, I tested it and it seems to work like that
thanks again for the help

Hello guys!
I'm looking for a big community for Django/DRF specifically, am I in the right place? ๐
inner kayak
I learned Django like a year ago and I'm getting back to it.
No I haven't used Swagger yet, still getting my hands dirty learning the basics to build confidence around the framework, the docs come later!
inner kayak
Do you recommend any project to get myself started? still going thru the tuts, that would help me alot ๐
kindred cosmos
Something usefull for your self
Build something that you yourself would use
Timetracking isn't a bad place to start
That's how I started
What I like to do also is finding a project you think is good and learn it
Even if you don't end up changing any code it's very intersting see how other people programmed their django apps
inner kayak
Honestly i'm lacking imagination, I need to build a project that is consistent enough to show it on my portfolio, yes its generally a good idea to read other people's code, its one the best way to learn thank you for the tip!
kindred cosmos
Try but you can get ideas from other people's code
Believe me, sometime I look at code and I am like damn I want to do that and implement it in my own project
inner kayak
Alright man thanks for the tips ๐
inner kayak
One last thing, which django app you recommend me reading?
kindred cosmos
I would high recommend looking at Raymond Hettinger talks on wirting better python code too
Hmm
Huge project
inner kayak
No way, didnt know OpenStack was built on django!
kindred cosmos
Parts of it are
That frontend peice is
Almost all of the api servers are built in flask such as nova, cinder and neutron
Those are intersting too to look at
I remeber looking at what it would take to wirte my own openstack nova driver
It didn't look too hard
Because their code is pretty good
inner kayak
Very interesting indeed, lost myself on reading now tbh x)
kindred cosmos
You're good man
inner kayak
Tell me, Is Django Rest considered the best way to create robust/secure API? because that's the reason i started learning it. do you think other frameworks offer better alternatives? (I prefer batteries included type )
kindred cosmos
Honestly the django rest framework belows me out the fucking water
It's so powerful yet simple
Anything I would ever want to do with a Rest api is possible with the django rest framework
I told a programmer, who has never touch django, or even knew about rest to make an api endpoint. He figured the django rest framework out in like 4 hours
inner kayak
That's encouraging, glad to know I'm on the right track x)
I'm surprised there is too few content
had a hard time finding a community
kindred cosmos
Good luck man! I figured this out and I ended getting a job for doing django deveoplment
I think it's crazy because I don't even have a degree
inner kayak
Thank you so much for the help mate. Really appreciated it ๐

No problem, I am glad to shoot the shit anytime

There seems to be millions of options
So far I've looked at Sanic, Quart, Starlette
Any recommendations?
north swift
@outer lynx may I get an explanation about the @app.context_processor thing?
north swift
Im unsure if its due to me using blueprints
I have currently an app.py implementing a blueprint with my routes
@app.context_processor
def _():
return {
'test': '123'
}
and that
outer lynx
Any context processor you create from the app is global
And will be applied to your blueprints
north swift
shouldnt I get to read 123 if I do {{ test }} in the rendered template?
outer lynx
yes
north swift
that's not happening
outer lynx
Any errors?
north swift
nope
outer lynx
what happens instead?
north swift
i'll double check really fast just in case
just blank
damn I'm not smart
did the app context under the app start
<.<
also, is the context_processor the place where I should initialize a db connection?
considering that I'll need to access it from the blueprints
north swift
so I'll need to connect to mysql with sqlalchemy on each .py file that needs it?
outer lynx
No
It is like blueprints
you write your database stuff in a file
you import it in blueprints
use it
then import it in your main
and init it
outer lynx

@uncut solar what matters most to you for an async framework? What will you be using it for? Iโve building our platform on startlette, which is among the newer but is the best performing, has a lot of momentum, and is written by the guy who also created the ASGI spec that other frameworks use under the hood: https://www.starlette.io/
It doesnโt have as much baked in as others but itโs actively developed and then again it also has a few things baked in that others do not (such as graphql, swagger, etc)
@uncut solar the others Iโve used and enjoyed the most over the last couple years are aiohttp and sanic. They all have their ups/downs so let us know if you have more specific criteria. Iโve only been writing async backend code for at least a couple years now and Iโve encountered most of the joys as well as pain points
uncut solar
Idk, the only requirement right now is websockets
Thanks, I think I'll go with starlette
junior cloak
@uncut solar starlette is great. they all handle websockets well. just gotta be really good about using async properly and all that jazz. the same guy also makes a good async framework for use with sqlalchemy and such

@hollow aurora i'm pretty convinced you can't do that with synchronous code like that - you'll need to delegate the client to a separate thread or you will block your webserver
alternatively, use something like asyncio with starlette as web framework, you'll need to search for a async websocket library though

Guys i am new to REST APIs. I am exercising and i am confused. There are many ways to do things. For example lets say i have Library object which has child object Book, when i make POST request should i add the Book objects as well or should i make separate url for adding Book objects to the Library?
timid arrow
you would usually go for a separate resource for books in this case, to keep api simple. That will allow you add/delete/modify books without modifying Library itself.

regarding WTForms, for anyone familiar, I'm using them for a multiple choice quiz and would like to have the ability, when the user gets one wrong, to reload the page and show which were incorrect.

@limber orchid
Can you provide what you've done till now?
limber orchid
yes, so its a standard WTForms class using one StringField() object and several RadioField() objects (I will post an example in a sec, opening my IDE now)
and then I'm using the 'validate on submit' method in my flask app to decide what to do.
I wish I could just find a nice list of all the methods and what they do but these particular docs I can't seem to ever find just like a nice cheat sheet of all the functionality...
this is the WTForms class
class Quiz(Form):
def no_slashes(form, field):
if '/' in field.data:
raise ValidationError('Be sure that you are NOT including /u/ or u/ with your username.')
name = StringField(u'username', validators=[input_required(), no_slashes])
q1 = RadioField(
"question 1 text?",
choices=[
('option 1','option 1'),
('option 2','option 2'),
('all of the above','all of the above')
],
validators=[CorrectAnswer('all of the above')]
)
submit = SubmitField("Submit")
this is the flask app
@app.route("/", methods=["GET", "POST"])
def quizlet():
error = ''
form = Quiz()
if request.method == 'POST':
if form.validate_on_submit():
try:
reddit = bot_login()
#reddit.subreddit('subreddit').contributor.add(reddit.redditor(form.name))
print(form.name + 'approved assigned')
return render_template('quiz_results.html', user_passed=True, approved_submitter=True, user=form.name)

@fringe fog fastapi is pretty nice. Iโve rewritten one of our internal services to Starlette (from Flask) and that one turned out great, so I am now working on the next, which will use FastAPI. The Python types as schemas idea of pydantic is great

Cool, glad to hear it. Iโm just digging into the docs now and it looks good.
If you donโt mind my asking what are you doing for your data layer? Sqlalchemy is great but not async, I was looking at the databases package as an option. After reading issues and whatnot I see that pydamtic models are separate which seems a little laborious but probably fine (it looks like they are working on that)
@meager anchor ^

@fringe fog i currently use databases with sqlalchemy core with starlette. it is not ideal, and there's some minor issues, but it's been fine for the most part in a production setting. i don't do anything fancy with models -- i just have the db tables, my pydantic object schemas match what the table fields will be, and pass a dict of the pydanctic model to it
havent done too much with fastapi as somewhat ironically ive just finished a total move to graphql for this particular project but i use pydantic a lot and starlette

Hi all
Need some help with Django. I'm learning it by making a blog app. Following "Django 2 by example" book.

ValueError: ModelForm has no model class specified.
This is the full error I'm getting
The file it refers to is views.py, i've made some changes to it to allow comments on posts
Here's the section I've made changes to.
def post_detail(request, year, month, day, post):
post = get_object_or_404(Post, slug=post,
status='published',
publish__year=year,

comment_form = CommentForm()
return render(request,
'blog/post/detail.html',
{'post': post,
'comments': comments,
'new_comment': new_comment,
'comment_form': comment_form})
If I get it right, the error is pointing at the line:
comment_form = CommentForm()
But frankly I don't understand what is wrong with it and how it is related to "ValueError: ModelForm has no model class specified."
frigid egret
can someone please help me?
vagrant adder
sure what's up
frigid egret

slender knoll
does the modelform meta have a model attribute
vagrant adder
@frigid egret i think you need to pass something as CommentForm()
can you post commentForm code?
frigid egret
1 sec
@slender knoll I have another form working fine. If that helps
class CommentForm(forms.ModelForm):
class Meta:
models = Comment
fields = ('name', 'email', 'body')
that's it?
frigid egret
@slender knoll
class Comment(models.Model):
post = models.ForeignKey(Post,
on_delete=models.CASCADE,
related_name='comments')
name = models.CharField(max_length=250)
email = models.EmailField()
body = models.TextField()
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
active = models.BooleanField(default=True)
class Meta:
ordering = ('created',)
def __str__(self):
return 'Comment by {} on {}'.format(self.name, self.post)
Here's class comment
slender knoll
i gave you the fix
slender knoll
wait
frigid egret
at least, I don't see it
slender knoll
vagrant adder
try putting model=Comment
instead of models=Comment
@slender knoll don't be so harsh
some are new here
slender knoll
im not being harsh ? this is how i teach people at school
frigid egret
I don't get what "modelform meta" is.
it's clearly not something that's in the code i've posted.
frigid egret
@vagrant adder which file is it?
slender knoll
class CommentForm means "define new class accessible by using CommentForm name"
(forms.ModelForm) means "base our new class on the ModelForm class"
and in there, there is another class, called Meta
slender knoll
it has to be set or list iirc
vagrant adder
class CommentForm(forms.ModelForm):
class Meta:
models = Comment #try putting model=Comment
fields = ('name', 'email', 'body')
Oh, got it... almost
now I gotta read on what's the difference between model and models.
cause it is confusing me rn
slender knoll
no
frigid egret
uh... where do I look then?

Hello guys!

hello

I don't know if it's a weird request but still.
I'm learning Django via the book "Django 2 by example"
I have a case here when I understand what this particular code given by the book is doing but I can't quite grasp HOW it does that.
Can someone be so kind to explain it to me in detail?
frigid egret
I could just skip through it cause it's working but I'd like to actually understand
I think it may be more related to Python in general rather than Django specifically
Can you take a look at least? @vagrant adder
vagrant adder
yeah i can try
frigid egret
Ok, so here's the code
post_tags_ids = post.tags.values('id', flat=True)
similar_posts = Post.published.filter(tags__in=post_tags_ids).exclude(id=post.id)
similar_posts = similar_posts.annotate(same_tags=Count('tags')).order_by('-same_tags', '-publish')[:4]
I have tags implemented and this next chapter is about filtering "associated" posts by looking at similar tags on other posts.
vagrant adder
what do you not understand
frigid egret
I don't quite understand how that last line works. I can see the result but it's not 100% clear to me how it's being achieved
vagrant adder
it just orders posts by given parameters
in this case these are 'same tags' and 'publish'
posts = Post.query.order_by(Post.date_posted.desc())
this is from my project^^
it orders posts by date posted
frigid egret
can't find what "annotate" does

Hello all! Am currently working on a Django project but got stuck in trying to add a 'next' parameter to url after user signed in via django's own allauth.
The idea is this, user tries to perform an action on the site in a page say 127.0.0.1:8000/addimage but isn't yet logged in, will be directed to the login page(either google or facebook social sign in) upon clicking on the link. Am trying to append the page where the user was(/addimage) to the sign in link that will be sent to either facebook or google depending on user's method so that upon sign in completion, user will be redirected back to the old page, in this case /addimage

hmm I am not quite sure what you need to do here. Which one is the example and which is your site and what exactly do you need to match? ๐
native tide
the padding between the ul and nested ul
fast escarp
ah you don't want additional space after "interest" for example?
reef rose
try ul.center { margin-bottom: 0; }
no that won't work
try changing your padding-top to margin-top in .center i think that'll do it
native tide
hmmmm still doesn't seem to work
fast escarp
hmmm are we sure that's the correct HTML part and you need just to fiddle the css?
@native tide what I mean is ... is this for some assignment or you're teaching yourself to HTML/CSS etc? The current way the lists are set is not great for accessing them with CSS. For example ul li will be applied for both levels and will mangle anything. I think there is a better way to write these, but I am not sure if that's what you need. ๐
native tide
mainly doing this for practice to understand the concepts
but it kind of bugging me
is there anything you could suggest on how to rewrite this
fast escarp
@native tide sorry I am at work, so I am answering slower I will have a look now
native tide
No worries
fast escarp
@native tide I would suggest don't go into two lists really, not needed at all in this.
<ol>
<li>Interest</li>
<li>Bananas</li>
<li>climbing stuff</li>

<ol>
<li>Jobs</li>

<ol>
<li>favorite quotes</li>
<li>"at first you dont succeed climb a giant building"</li>
<li>"A Banana in hand is worth two on a tree"</li>
</ol>
Okay
fast escarp
I would also suggest to use
li:first-child {
color: red;
}
this will change only the first element in all <li> elements so it will be easy for you to manipulate these

Hi excuse me Does anyone know how to integrate Django with Angular
vagrant adder
sounds like google time
native tide
@late gale , do you need to integrate Django with Angular? you can treat them as two seperate projects
late gale
Ik but Django is so bad in templates so i want to integrate it with Angular
Django is so powerful in backend while angular is powerful in frontend
i want to mix them
but i cant understand from google
that's why i am asking here
do you know how @native tide
native tide
there's probably a way to integrate them into a one project, but, personally, I wouldn't do that
late gale
why so what're the cons
native tide
if you want tu use django as a backend and angular as a frontend - make your django a rest app
and consume it with angular
late gale
typically yes
i want to integrate them then i gonna continue on learning both and updating the web app
native tide
typically? I'll assume you are new at angular. My advice: go through a decent Angular tutorial where you will, no doubt, learn about consuming rest apis
after that, go to django
where, instead of html, (default), you will have to return dictionaries
late gale
thank you
native tide
np, but ask if you have more questions, even if you think the questions are stupid
it's just that I think, you'll have a lot of problem if you tackle both at the same time
for Angular, I'd really recommend tutorials from Maximilian Schwarzmรผller
note: I haven't done any tutorials from him, but I've heard a lot of good things about his tutorials from multiple sources
vagrant adder
Both
native tide
I'd say it depends what you want from it
if the goal is to learn, use both
but if you want to have a blog? use django
if the two tools are the only options
late gale
thanks
native tide
but if the goal isn't learning, there are better tools than django
late gale
nope i am not learning i want to make a professional blog and very responsive
native tide
if you don't want to learn prrogramming, I'd suggest looking at existing services

hi everyone
i need help with flask
im on windows 10 (yes, i know)
and am using VS Code
im following Cory Schafer's tutorial
but unfortunately, he uses MacOS
this is my code:
from flask import Flask
app = Flask(__name__)
@app.route("/")
def index():
return "Hello, world!"
the name of my file is flasktestapp.py
when i try to do set FLASK_APP=flasktestapp.py and then flask run, it doesn't work
what should i be doing?
somebody please help
somebody help please
anybody
SOMEBODY

sigh
willow garnet
@winged island buddy, you have to be more patient. Everyone here is a volunteer. I invite you to ask your question in a help channel, that might get you a quicker response
rare oar
hey harbar yeah the web scene here isn't as fast
by flask run I think you mean a command?
oh nm flask run is a console command
This may help you: http://flask.pocoo.org/docs/1.0/tutorial/factory/
north swift
@timid arrow sorry I didnt notice your response, for example put a breakpoint on a route form post and check the object that I'm receiving, change its values, etc.
north swift
Maybe its me not understanding how flask works, I usually debug my .py scripts by running it on debug mode (I'm using spyder ide if that helps), doing that with flask just wont run the app.
vagrant adder
You can't debug flask apps with breakpoints
stray nexus
@winged island if still needed: to use flask run in a directory you need your main file to be in myapp/init.py and set the flask app to myapp.
north swift
@vagrant adder then what's the approach to debug stuff?
vagrant adder
use print statement
A lot
And i mean, A LOT
Since you can't just make a breakpoint, you need a lot of info to know what's happening
north swift
that's a bit and by bit I mean a lot underwhelming
vagrant adder
print or pprint will do the job
fast escarp
@north swift to add to saki's print statements ... sometimes it will crash and you will still be able to see the print statement but you should have to scroll through all of the crash dump, so make sure you're reading from the top down when checking for the print statement, if it's not there, it crashed before that, if it's there it will give you better idea where crashed. ๐
runic musk
any idea why the override threed.js doesn't seem to be getting used?
i tried dropping it to root and root/js
north swift
@fast escarp I mean, sure, but its the first time I dont get to play with the request data before sending the response
fast escarp
@north swift sure, I didn't mean it in a bad way, just helps overall whatever you're building. And if you're doing the front with JS for example alert and console.log are your best friends really. ๐
north swift
my issue is that I need to start a process on a post request and personally I dont think printing everything is a good way to find errors
fast escarp
hmmm why is that? what do you think it will be better approach?
north swift
just allow us to stop on the request part and debug normally as other languages?
I'm used to java (spring dev) and I can literally go step by step on everything and modify data on the go if I need it
fast escarp
I know, that would be great really
north swift
I'm actually used to do it on python overall too
I do 90% of my python work on a temp file loading stuff as I need
fast escarp
Yeah, but not always the best approach in Python
timid arrow
never had to run debugger with flask, but I think you still can do it, why not.
north swift
it just wont start the app
timid arrow
I mean, here is tutorial on how to set it up in VS code
so it's definitely can be done
north swift
guess I'll try that later but I dont really want to move away from spyder
timid arrow
I doesn't' matter which IDE to use
it's all about running flask app with specific command line args
and that is it
north swift
hmmm I wonder if that will be a problem since I use flask-socketio
will give it a try when I get some spare time, now I sadly must attend this meeting
rare oar
instead of print statements, use the logging module
I use the Django Debug Toolbar and it is super helpful
Also it does look like there is a flavor of the "Debug Toolbar" for Flask
solid cave
I'm trying to serve my flask application using uwsgi, I did the tutorial and got it working but now trying to get my actual flask app and running into road blocks because I have it configured as a package instead of running from a single file (I think thats the right terminology), in the pocoo docs for uwsgi it says to run something like this:
$ uwsgi -s /tmp/yourapplication.sock --manage-script-name --mount /yourapplication=myapp:app
but this doesn't seem to be working, I'm not sure why it says to use a sock here but I made one anyway, it keeps saying that my package name doesn't exist, i have been running it like this, but have tried different configs as well and nothing recognizes correctly:
uwsgi -s /tmp/flask_audit.sock --manage-script-name --mount /app/py_sox=flask_audit:app
I'm not sure what i'm doing wrong but it feels to me like i'm not even on the right track because this is nothing like the tutorial I followed
My app's index.py lives in /app/myapp/flask_audit and the root dir for the whole app is /app/myapp
I've been running it in development with flask run on a specific port but need to move it to a web server now

I moved to django from php, i just used django template to display a table from database which has numbers in it, i want every column of that table to have sum total please anyone can guide.

@everyone

Anyone please help
still briar
@native tide Could you show a snippet of your current views and template?
Since a sum wouldn't be in the database, you would have to calculate it first I'm views and then provide the data as an additional argument to your template while rendering.
native tide
This is very difficult i ha e tons of tables
I want to use like {{entries.amount.sum}}
Is there a way?
@still briar i solved it by using aggregate function but that is very time taking because i have like 1000 tables and this means i would be using aggregate 1000 times sepately in views
still briar
Usually if you want to pass that kind of data to your template, you would do it like ```py
sums = ...
return render(request, 'something.html', { 'sum': sums })
What does your view function in views.py look like?
native tide
Thanks to everyone i finally found a library
Django-tables2
@still briar I am talking about automation, thats what django is about, i create models and django automatically creates db, forms and tables now yay!

hi guys I am just going thru the django channels tutorial but it is written in django 1. something and i am currently using django 2.2 and I ran into some issues while trying to write the equivalent syntax
so the first urlconf is for my mainproject direcotry and teh second one is for an app. When i type in the url chat/someroomname shouldnt the views.room function be called? When I type chat/someroomname the views.index is called instead and I am confused as to why
still briar
It looks correct to me. Try going to chat/someroomname/ with a slash at the end.
Normally, an include could look like this, where you fetch the list from your app.
urlpatterns = [
path('<page_slug>-<page_id>/', include([
path('history/', views.history),
path('edit/', views.edit),
path('discuss/', views.discuss),
path('permissions/', views.permissions),
])),

Two years ago I took a short web dev course with Google App Engine using python and jinja, urllib2, webapp2.
Now I want to privately set up a small website from which users can make REST/RPC calls for crypto to an unrelated node. I want to stick to Google Web Engine and Python. The page itself will be minimal w.r.t. to storage required.
It should e.g. enable people to broadcast payments to the bitcoin network (web wallet).
The web engine is just to deploy that web page conventiently. It will have some light weigth interface
What's the options I can go for here? Is jinja serious enough for my demands?
I have some friends handling the network communication with Twisted/Klein. Is the suitable? But I also don't see people on the web using it. Does something like Flask do all things at once? What's other options.

Can you become a web developer without learning JavaScript
steel tiger
Not a great idea and you will learn it in industry anyways
I have not done js as my projects have never needed to be reponsive
still briar
You could become a backend developer and work with Python!
It's of course good to know javascript, but you don't have to be proficient. Nowadays it's all about frontend frameworks anyhow.

waxen cedar
hey guys
i really need help right now
so i created a website and bought a domain name on GoDaddy website
but i have no idea how to link my code to the website
i would really love to be helped right now
jade egret
@frigid egret your not using that import anyway? and you have an s there is that supposed to be something else
frigid egret
Well yes except docs say that it has to be "sitemaps" specifically
If i try to change it to "sitemap" it doesn't render the page
waxen cedar
can somone help me ?
frigid egret
@waxen cedar Which guides have you tried following?
frigid egret
@jade egret If you look at the docs, you'll see that I'm trying to do it exactly as in the example. And it seem to be simple enough.
jade egret
can you post a link, so im looking at the same thing
waxen cedar
can someoen help me ?
frigid egret
@waxen cedar be patient please
waxen cedar
okay
jade egret
The sitemap view takes an extra, required argument:ย {'sitemaps':ย sitemaps}.sitemapsย should be a dictionary that maps a short section label (e.g.,ย blogย orย news) to itsย Sitemapย class (e.g.,ย BlogSitemapย orย NewsSitemap). It may also map to anย instanceย of aย Sitemapย class (e.g.,ย BlogSitemap(some_var)).```
I'd say that would suggest you can put your PostSitemap thereYes, and I did that, didn't I?
It may have something to do with my project structure. Because it says "unresolved reference sitemaps" when I hover over it
jade egret
if you look further down you'll see examples.
@waxen cedar maybe try their website builder just to have the structure to look at, it seems you use ftp to add your webstuff
frigid egret
If I change path to "mysite.blog.sitemaps" there's no error but it fails to render the page
Yes, and I'm doing it just like in the example.
This is why I'm saying it might have something to do with the structure
waxen cedar
oh god i dont have that much knowledge with web @jade egret
my website is online but idk how to add my script to it
frigid egret
Because I know it's not set up exactly the same way as suggested by docs, it's because of how PyCharm community edition handles django projects
jade egret
have you changed it since? your sitemaps above is undefined, its not in the examples
how is it hosted atm? its running on gd?
waxen cedar
i dont know any of those
i just know that i signed up on GoDaddy
and bought a domain
thats the link
i just dont know how to put that script inside of the page
jade egret
what script?
frigid egret
@waxen cedar are you trying to host it directly from your machine?
frigid egret
You'll have to install a web server to do that. Like Apache for example
waxen cedar
okay but idk how to use Apache
frigid egret
try googling apache web server setup
frigid egret
There's no simple answer to "how to use apache" I'm afraid. That's a complicated topic
waxen cedar
okay
frigid egret
@jade egret can we go through it step by step cause I don't quite get what you mean
frigid egret
Ok but I don't want it to use static views only
I'd like it to generate the sitemap based on existing article pages.
This code given as initiation example should be working fine if I get it right:
from django.contrib.sitemaps.views import sitemap
path('sitemap.xml', sitemap, {'sitemaps': sitemaps},
name='django.contrib.sitemaps.views.sitemap')
Given that I've added sitemaps to my installed_apps
Am I getting it right?
Cause that seem to be the problematic part
jade egret
try {"sitemaps": {"post": PostSitemap}}
frigid egret
path('sitemap.xml', sitemap, {"sitemaps": {"post": PostSiteMap}},
NameError: name 'PostSiteMap' is not defined
small m by bad
frigid egret
Oh right
Ok, it works. Thank you ๐
So it takes PostSitemap class and gets all items from it as separate entries, right?
jade egret
havent a clue tbh, ive tried wrapping my head round django before and just couldnt do it, but yea it would seem to be making instances of that class as & when, not sure where that "post" label will come into play/be used
frigid egret
Hahah. Thank you anyway. It works now ๐

Hello all, I create my first project, and i have some trouble with Django.
I need create URL path, generated of more one Slug:
urls.py in applications
from django.urls import path
from . import views
urlpatterns = [
path('<category_slug>/<subcategory_slug>/', views.subcat_slug, name='subcategory'),
path('<category_slug>/', views.category, name='category'),
]```But I get no URL's combinations I need
I need to have URL's <subcategory_slug> that are included with the composition available on the way <category_slug>, and it turns out that all subcategories are available with any combination of categories
models.py
class ProductCategory(models.Model):
category = models.CharField(unique=True, max_length=30, blank=None, null=False, default=None)
is_active = models.BooleanField(default=True)
slug = models.SlugField(unique=None, blank=None, default='')
class ProductSubCategory(models.Model):
subcategory = models.CharField(unique=True, max_length=30, blank=True, null=True, default=None)
category = models.ForeignKey(ProductCategory, max_length=30, blank=None, null=False, default=None, on_delete=models.PROTECT)
is_active = models.BooleanField(default=True)
slug = models.SlugField(unique=None, blank=None, default='')```views.py
def category(request, category_slug):
category_slug = get_object_or_404(ProductCategory, slug=category_slug)
return render(request, 'products/category.html', locals())
def subcat_slug(request, subcategory_slug, category_slug):
subcats_slugs = get_object_or_404(ProductSubCategory, slug=subcategory_slug)
cats_slugs = get_object_or_404(ProductCategory, slug=category_slug)
return render(request, 'products/subcategory.html', locals())```@pale fiber You forgot to check if the category is the subcategory's category.
It current fetches subcats_slugs and cats_slugs. Try checking subcats_slugs.category == cats_slugs
pale fiber
@still briar
Oh, thank you very much.
I check it before return function, and it all worked.
I am very grateful to you.
pale fiber
I make this. Thanks for your rectification, otherwise 500 error would come out, I did not know about it.
I think this need make all render function's?

Not sure what you mean.
There's a 404 error you can import and raise in your view function, in case you want to keep things consistent.

Hi all
I have a problem with PostgreSQL.
can't create a database because user fails authentication.
All threads on SO with similar problem are about already having both user and database. Which doesn't work for me because I only have a user.
postgres@ubuntu:/home/vm$ createdb -E utf8 -U blog
createdb: could not connect to database template1: FATAL: Peer authentication failed for user "blog"
did you create your user?
frigid egret
Yes, I have a user
vagrant adder
also, try -u
frigid egret
I even created a second one just to be certain it worked
vagrant adder
try -u instead of -U
vagrant adder
yes
frigid egret
same result. "help" section also says it's high case -U
frigid egret

frigid egret
like that?
vm@ubuntu:~$ createdb -E utf8 -U blog blog
createdb: could not connect to database template1: FATAL: Peer authentication failed for user "blog"
Yea, tried
It results in a bunch of SO threads
And they are all about already having user and db. There are some fixes for that but I can't use them cause I don't have any db files to allow access to the user.
Like this one.
Also, somehow this is the only page I could find where someone has exactly the same problem. But it's really weird cause somehow it's on poker forums Oo

"could not change directory" is just a warning
the user was created only once

Hi, I'm new to JS and web development in general, I wanted to make a textarea that expands as the user types with jquery, this is what I've come up so far js $("textarea").on("keydown", function () { $(this).css("height", "inherit"); const height = parseInt($(this).css("border-top-width"), 10) + parseInt($(this).css("padding-top"), 10) + $(this).scrollHeight + parseInt($(this).css("padding-bottom"), 10) + parseInt($(this).css("border-bottom-width"), 10); $(this).css("height", `${height}px`); });, but it straight up doesn't do anything, any suggestions?

Can you provide a jsfiddle, codepen, something similar?

mmh, sorry if this is a stupid question but what's jsfiddle and why would I need it?

Hey all, given I want to use filter to go over a reverse object relation, I know that if I want to explicitly filter on AND, I would put them in a single filter expression... example filter(a__b__c=1, a__b__d=2). I know if I want to do AS WELL AS, I could chain the filter. My question is about making custom managers. If I wanted to do something like MyObject.ranked().current_season().stats() Where ranked and current_season are filters, and stats is some type of annotation, is there any patterns for the first case to make a call to filter that works in the first example? In this case I would want ranked AND current_season stats instead of ranked AS WELL as current_season stats. I'm just trying to find the right way to nicely represent it in a manager. Sorry if this is confusing.
