so there is a urls.py in the Python package folder (within the project) and then there is a urls.py in each individual app folder. how do they relate to one another exactly? when you visit a site, which one gets used first?
empty anchor
i dont think there should be a urls.py in every app-folder by default
so there is a
urls.pyin the Python package folder (within the project) and then there is aurls.pyin each individual app folder. how do they relate to one another exactly? when you visit a site, which one gets used first?
@native tide
the urls.py in your main folder contains all your urls to different views
empty anchor
you can import a view from a different app and then create url for it
yes you're right that there is not a urls.py in every app folder by default
@native tide Yes
lets say you have a app named Login then
native tide
so whenever you add a path to a urls.py file that is in an app folder, you have to include it in the project urls.py...... unless you go to like http://127.0.0.1:8000/<app_name>/
right?
from personal.views import home_screen_view # personal is the app
urlpatterns = [
path('admin/', admin.site.urls), # pre-loaded with Django
path('', home_screen_view),
]
you don't have to import the view to the project urls.py if you go to the URL for the app itself, is that right?
empty anchor
from Login.views import someAPI
urlpatterns = [
path('login/',someAPI.as_view())
]
from personal.views import home_screen_view # personal is the app
urlpatterns = [
path('admin/', admin.site.urls), # pre-loaded with Django
path('', home_screen_view),
]
@native tide its better to use the root folder urls.py
native tide
oh wow, really? like, all of the time? or at least most of the time?

that makes sense to me

Hi there, anyone knows how to import N classes from a directory and append to an array ?
chilly zenith
hey everyone! glad to be a part of this community
is this the proper channel to ask django / DRF type questions?
native tide
yes
chilly zenith
cool! i am pretty new to DRF and was curious: what is the standard method for views...ViewSets or function-based views? does it matter?
im a java dev by day so we have controllers (which i understand are views in Django land) and do what would be similar to function-based views
(i use spring boot so it is annotation driven)
native tide
i am a newbie, so maybe a pro will chime in but, here is how i understand it
it goes visit site -> urls.py -> views.py -> (optionally) models.py / DB call -> HTML -> client
views are functions
def members(request):
list_of_all_members = Account.objects.order_by('first_name')
context = {'list_of_all_members': list_of_all_members}
return render(request, "lb/members.html", context)
that is a view
does that help at all?
chilly zenith
a little... i understand the chain you mentioned above but trying to see what is the "standard" in regards to this https://medium.com/@ksarthak4ever/django-class-based-views-vs-function-based-view-e74b47b2e41b
native tide
well i have gone through literally 6 long Django tutorials and i have only seen function-based views
but again, i'm still a beginner 🙂
chilly zenith
haha ok cool that does help tbh! ima watch some more videos and see what is up
im leaning towards function-based views as well
native tide
godspeed
chilly zenith
thanks @native tide !
native tide

chilly zenith
thanks for that feedback weep! i went with the ViewSet route for now since i have a better understanding now that it creates most of the endpoints you need auto-magically
native tide
@empty anchor always?
they're definitely nice but sometimes you need pages that don't need all of that included functionality
and I'm under the impression that the added overhead comes at some performance cost, vs just a simple FBV where it only contains what you explicitly define
empty anchor
most of the times mark ! but you got a point

hi all. question regarding django timezones. backend is returning datetimes in ISO 8601 string format (like normal) via DRF endpoint.
front wants back to convert all datetime objects to user local timezone. generally i would think that front should do that conversion based on the timezone details provided from the DateTimeField. thoughts?

Someone can suggest a good tutorial course to develop ecommerce website with django?
because now i found only old tutorial that uses old version of django (1.11) and im searching for tutorial with django 3
opaque hemlock
depends what you are doing, but generally not a huge difference between 1.11 and 3.0. we were running 1.11 for first while at my office couple years.. since then i've slowly brought us up to 3.0. 99% the same for what we do. tutorial for 1.11 might still be useful

The frontend has a built in way to convert to the local time with JS: (new Date(datestring)).toLocaleString()

Now i know this may not be the right place to ask, i got the UI (CSS) of the speeddial, but next I'm trying to get/put the functionality on clicking of each and every button...
The page from which i extracted the info was a packed app... and had the location chrome-extension://<id>
Which means it's a chrome extension and Vivaldi is chromium based
When i type its location in addressbar it doesnt appear. Is there any other way i can access it ?
restive kindle
Isnt it chrome-extension. Plus your message made be switch, surprised I havent heard of this before, its pretty good.

@restive kindle it's a packed app, and yes it's strange. But i think because it's a chromium based so it allows chrome extensions
And I'm using debug-packed-apps flag to inspect elements

maybe you could take the approach of

{% for vouch in vouches %}

<td>{{ vouch['author'] }}</td>

<td>{{ vouch['comment'] }}</td>

hey y'all! Is anyone of you familiar with the pushshift API? I was using psaw and basically used their demo example to grab posts from 2017. But somehow it retrieves only the latest posts and not from the time indicated:
from psaw import PushshiftAPI
import datetime as dt
api = PushshiftAPI()
start_epoch=int(dt.datetime(2017, 1, 1).timestamp())
data = list(api.search_submissions(after=start_epoch, subreddit='neo', filter=['url','author', 'title', 'subreddit', 'num_comments', 'comments'], limit=10))
print(data)
This is what the code above returns for me, if I use limit=1 instead of 10:
[submission(author='anonboyGR', created_utc=1590054802, num_comments=0, subreddit='NEO', title='Pi Network Cryptocurrency', url='https://www.reddit.com/r/NEO/comments/gntymq/pi_network_cryptocurrency/', created=1590047602.0, d_={'author': 'anonboyGR', 'created_utc': 1590054802, 'num_comments': 0, 'subreddit': 'NEO', 'title': 'Pi Network Cryptocurrency', 'url': 'https://www.reddit.com/r/NEO/comments/gntymq/pi_network_cryptocurrency/', 'created': 1590047602.0})]
notice how this is in fact not from 2017...

def __repr__(self):
return 'Blog post' + str(self.id)```@native tide but i am trying to update it
native tide
well yeah but you need to pass your BlogPost Model to the db. you just randomly do db.session.commit()
how does the db know what it is supposed to do?

I am working with Flask and as far as I understand unchecked checkboxes are not serialized in the form subission POST request.
Question is, how do I check for existence of a given checkbox within the if form.validate_on_submit() call?
At the moment, I am checking for existence in the following way:
if request.form['show_logo']:
# Do stuff
The problem is that when the checkbox is not checked (hence not serialized and sent in the request), the above if statement returns a KeyNotFoundError
tender crater
Solved, I simply ended up checking for its existence in the form fields:
# check for checkbox existence in returned form
if "show_logo" in request.form:
# do stuff [...]
As default, django creates static folder inside each app. But i want also to create a static folder outside the app, this static folder outside app has some files that aren't app-related, it has files that are used all-around in the site. So how can i create static folder both inside each app and both one outside the apps folder?
i mean that
I red about STATIC_URL STATIC_ROOT inside settings.py, but i didnt understand very well

Anyone know how to do form validation in flask
tender crater
@native tide have mid-level experience with Flask, where did you get stuck?
native tide
@tender crater thanks for the reply!
so i have a form
and on submission it sends the data to routes.py right
# After a test is submitted
@app.route('/submit/', methods=['POST'])
@login_required
def submit():
data = request.form
p
return redirect(url_for('userprofile'))```when submit is pressed, the contents are POST to routes right
and data = request.form
my question is
how can i do form validation, so the user can only submit the test once all of the questions are answered?
pls
tender crater
how can i do form validation, so the user can only submit the test once all of the questions are answered?
@native tide do you mean that users can currently send partially complete forms and you specifically want to prevent that from being allowed?
tender crater
If that's the case you should specify validators (very easy with wtforms) in your form definition, example:
from flask_wtf import FlaskForm
from wtforms.validators import DataRequired
from wtforms import StringField
class CoolForm(FlaskForm):
name = StringField("Your name here", validators=[DataRequired()]
surname = StrinField("Your surname here", validators=[DataRequired()]
This will prevent the form from validating when those two fields are not filled out.
tender crater
Right, in flask you have to declare your form in a class somewhere as specified in the documentation https://flask.palletsprojects.com/en/1.1.x/patterns/wtforms/, it'll make your life easier
native tide
to make it a wt form ? @tender crater
theres a reason we didn't use wt forms
im not sure why i'll ask my team mates but we aren't using them for a reason
tender crater
@native tide got it, to be honest i always sticked with way back when I started as it was suggested in the official docs and it is very well documented
now I really wonder what's preventing you guys from using it 🙂
native tide
do you know how to validate for a html form?
@tender crater reason we dont use wt forms
is because there is a varying number of questions per test
tender crater
@native tide Uh, that's a cool use case
native tide
huh
tender crater
Anyways, I would personally write a helper method that takes your form as an argument and performs all the checks on your form
But haven't to much experience outside wtforms. Will give it some thought in some spare time
Sorry, wish I were more helpful

can someone tell me why flask form is giving me wrong error
its not showing me "Invalid email address"

distant trout
oh
but i cant use Email() alone
it gives me error if i dont use email_validator
native root
What's the error it gives you?
ah
That means it must be installed, not that it must be put in that spot
distant trout
oh
native root
Validates an email address. Requires email_validator package to be installed. For ex: pip install wtforms[email].
distant trout
let me try it without the email_validator argument
oh wow lol it worked
thank you so much, this has been bothering me for 2 days now

The Email() validator treats its first argument as a custom error message
so that's what was happening 👍

Hi all, did somebody worked with flask and multi threading? I have a sensor who sends a lot of stuff over protobuf and i want to display the results as a interactive webpage. So the sensor company recommends to get a dedicated thread for receiving the data.
normal vapor
Hello all, I'm new to python and I'am building a flask app, that keeps track of orders/comissions, keeps photos of them and all the information about them and calculates all the finances. How can I make running the app and database (i'm using XAMPP MySQL db, becouse I had expierience with it using PHP) easiest way for end user, I don't want to host it publicly on the web for security reasons, just locally on the computer or local network, is there any way of making it into exe file or i should use something else than XAMPP? Wish you all health!
gusty gate
don't know how big your database will get, but look into a Raspberry Pi as host or docker image. XAMPP is great for development but all this root access to your database can easily destroy your db
normal vapor
What would you recommend using instead of XAMPP?
gusty gate
like i sad: raspberry pi hosting the mysql server or a bit more complex: install a docker engine on your pc and docker you flask app an mysql server. with docker you can create a save env. for you app so that only flask has access to your docker mysql database.
your pc is running on windows?
normal vapor
Yes
gusty gate
there is also a mysql server installer for windows
it's a bit more complicated than XAMPP but I always recommend to create a dedicated user for an app in mysql
normal vapor
I will read more about those solutions, thank you for advice!
gusty gate
there is also a tutorial for docker hosting the mysql database
give it a try so you can easily move your db to other host if you later need it
normal vapor
To be honest I'm totally new to this docker concept and need to expand my knowledge about it, but it looks like better way of deploying than intalling xampp on end user pc 🙂

@quick cargo there are special flags that need to be enabled before to inspect the UI

what u wont be able todo is just send a request to the site and get the content from it
im not sure how you would go about loading it with JS enabled and let it render
dark hare
@toxic marten firstly you have typo in your template, should be 'src' not 'scr', in your 'src' you are putting two variables that are generated next to each other in the path that django is looking for. Have you inspected in the browser to see what path django is rendering?

You have to make a POST to it so that we can see a value printed.
There doesn't seem to be any POSTs to that endpoint.
A screenshot is not necessary - just the console output (which contains the value printed).

Crossing posting this from the databases chat, could someone help me out:
Is it possible to prepopulate a Model in Django with data scraped from a website, and then access that data later to post onto a Django application? I tried to write a migration to do this for me, but I think I might have written it incorrectly because it seems to give me multiple instances of the model rather than a single instance with all of the data.
queen bough
@topaz charm Yes. Migrations are unnecessary and probably incorrect. The easiest way is to run the scraper contained in the Django environment and create and save models to the DB.
If you are using Scrapy you could try this module - https://django-dynamic-scraper.readthedocs.io/en/0.13-dev/introduction.html, though I've not used it.
@topaz charm Yes. Migrations are unnecessary and probably incorrect. The easiest way is to run the scraper contained in the Django environment and create and save models to the DB.
By create I mean:
scraped_value_1 = '...'
scraped_value_2 = 0
db_item = Model.objects.create(string_field=scraped_value_1, integer_field=scraped_value_2)
db_item.save()
@queen bough Would each item I scrape be saved as a unique instance of the model? I.e I'm trying to scrape a list of 500 songs from Rolling Stone magazine, would these be saved as 500 instances of the model I create to hold each songs info, or a single model with 500 entries containing info for each song
queen bough
No, 500 instances of the model.
for i in range(500):
...
db_item = Model.objects.create(string_field=scraped_value_1, integer_field=scraped_value_2)
db_item.save()
@app.route('/posts/pinn/<int:id>', methods=['GET', 'POST'])
def pinn(id):
post = BlogPost.query.get_or_404(id)
if request.method == 'POST':
post.pinn = request.form['pinn']
if post.pinn is True:
post.pinn = False
db.session.commit()
return 'gotovo'
else:
post.pinn = True
db.session.commit()
return 'gotovo'
else:
return render_template('posts.html', post=post)```it seems i am missing something
<button type="submit">Stick</button>
</form>```what could be wrong in here? @queen bough
queen bough
G2G for a while, I should be back in a few hours. Ping me with any further questions.
queen bough
i.e. You want to monitor without having to submit it?
That will require AJAX to post every time a new option is chosen.
BTW, this:
if post.pinn is True:
post.pinn = False
db.session.commit()
return 'gotovo'
else:
post.pinn = True
db.session.commit()
return 'gotovo'
Can be simplified to this:
post.pinn = False if post.pinn else True
db.session.commit()
return 'gotovo'

I'm using the django tutorial for the poll app, and I just finished the step "write your own view". When visiting localhost:8080/polls, it has a 404 not found error. ```
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/polls
Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
admin/
The current path, polls, didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

I need some help regarding serving a flask app. I can SSH into this linux server and I have my own directory in that server. In that directory I have code for my flask app, and also an index.html file. I have a URL that will load index.html. How do I get that URL to load whatever my Flask app is displaying?
Would I have to contact the Server Admin to get that to work?
quasi ridge
are you running the flask app?
if so, it should have printed something out like "listening on port 1234"
frail estuary
Yes, that works fine
quasi ridge
so in your browser, put http://your-servers-DNS-name:1234
if that works; great; if not, you may indeed need to talk to the admin
quasi ridge
exactly how does it fail?
quasi ridge
I'm guessing the sys admin needs to "open" port 8080
frail estuary
Is there a way to get it to load without having to specify the port
quasi ridge
probably not; if you don't specify the port, your browser will choose 80 or 443, and place.com almost certainly uses those ports itself
another option is to get your own host, where you are the admin. It costs some money, but you get complete control
frail estuary
the thing is it's not my project. I just know how to build python apps, but I've never deployed them like this before
this is a big company server
I'll email the sys admin I guess
and yeah, trying to serve to port 80 or 443 gives me permission denied
quasi ridge
well that's because you're not root.
If you try as root, you'll almost certainly get "Address in use"
frail estuary
Is it possible for the index.html webpage to redirect to the localhost url?
quasi ridge
I think so -- I think you can put a "meta" tag in there that causes a redirect
frail estuary
hmm, I tried doing <a href="127.0.0.1:8080"> in index.html, but that gives me the error:
The requested URL /dashboard/127.0.0.1:8080/ was not found on this server.
no wait, my bad. I had a typo. Doing a link to that just loads localhost on my machine. It doesn't redirect to the localhost of wherever the app is being run from

Hey,
I'm using Django, and I've already defined a DetailView for my blog posts. However, I'm looking to create another view that filters for the specific users posts so they can refer to them. Is the best way to do is via another view that utilises DetailView?
What I was thinking was to implement it this was this way:
`class YourOwnPostDetail(DetailView):
""" Shows authenticated users their own posts. """
model = News_Post
template_name = 'user/posts.html'
context_object_name = 'post'
def get_queryset(self):
user = get_author(user=self.request.user)
qs = super().get_queryset()
return News_Post.objects.filter(get_author(user=user)`)
Of course, this is not the finished product for the class. What would you guys think?

@maiden tulip It really depends on your use case. Django is more battery complete, Flask is easier to pick up and can be extended if needed. There is not really a "this is better". Especially if you are working with dynamic media files, Django can be very painful to use.

tired root

dark hare
@real hare ListView is something you may want to take a look at
@topaz charm in your projects root directory you should have a manage.py and a settings.py file
in there is your INSTALLED_APPS you need to add your app into this list. When runserver is called your app will try to load and attach each apps module to your application. So in installed apps you can define where to point to your apps.py config class, which defines the setup for your individual apps

Hey is it better to use flask or django for a REST API
quick cargo
it depends
you can use either
Flask is more lightweight and would probably be simpler for you
Django can be a bit overkill for a simple rest api
topaz charm
@terse surge , yeah I was running the command python. What’s the difference between this and the shell, and why should I run the shell?
terse surge
Directly typing python, just starts the interpreter.
Using manage.py within a django project sets the environment so that you can interact with your project objects in the shell. As noted here:
We’re using this instead of simply typing “python”, because manage.py sets the DJANGO_SETTINGS_MODULE environment variable, which gives Django the Python import path to your mysite/settings.py file.
@topaz charm
marsh canyon
by using the django shell, you get access to explicit model methods which allow for easy access(queries, calculation, etc). If you are using the python shell, then you will have to connect to the database first (example is using sqlite3 lib if ur database is sqlite) ,and then run sql commands to fetch the tables and so on, the django shells makes it a lot easier

I have a local web server. It is in flask. This web server lives in a computer. This computer is connected to the internet. However, I cannot accept incoming connections from the internet to this computer because it is blocked by a firewall. I do not have the privilege to allow incoming connections.
I also have a remote web server. This is also in flask. I have total control over the remote web server.
How can the remote web server send requests to the local web server?
Any workarounds are ok too. But speed is important, it needs to immediately respond to requests.
When the remote server received a foreign http request, it needs to request computation from the local web server
For example, maybe a workaround is for the local web server to log in to the remote web server and keep reading the http logs every second and if there's a change it would push the payload

Hey guys, when using django, is it possible to run query that sum records which are same value of field that is different than each other? for example
class Track(models.Model):
title = models.CharField()
disc = models.CharField()
class Report(models.Model):
track = models.ForeignKey(Track, on_delete=models.CASCADE)
So in this case i wanted to get sum of all disc 1 's track report

can you rephrase the question?

can someone explain what wordpress developers do
doesnt setting up a site with wordpress not require coding
verbal obsidian
Hmm
It might depend on the company, but I'm mine, 'wordpress developers' are usually the php guys
they modify the style to the client's needings
sometimes, when they have special needs, they write their own plugins in php
somber crater
doesnt that not require coding though
somber crater
like isnt wordpress just like wix or something
somber crater
yeah ik
verbal obsidian
for example, woocomerce, manages all the payment stuff
somber crater
yup
verbal obsidian
sometimes the client needs more specific stuff and needs to be programmed
somber crater
but thats occasional
verbal obsidian
fairly common in my company
verbal obsidian
and when what the client needs somethign that cannot be achieved with wordpress
because it'd be extremely bloated with plugins
they hand those projects to my team
and we do it in django
somber crater
and is that only for one part of the site
so you custom develop a certain part of it but the rest is still on wordpress?
verbal obsidian
sure thing
that's actually my current project
we use wordpress for the 'CMS'
for the blogs, news and such
and then for the more complex stuff, django
although I'd rather make everything in django
but not my call
somber crater
wordpress development seems easier than other programming jobs
verbal obsidian
it is
but they often do more than 'just wordpress'
again, it might depend on the company
somber crater
alright, thanks for the info
verbal obsidian
NP
somber crater
django is python right
but I heard python is really slow, so why is it used for websites?
dawn ore
Wordpress development is not necessarily easier than any other programming jobs.
It just depends on what features you are trying to build ontop of wordpress
Can be any complexity pretty much
@somber crater Because python is fast enough for most tasks

its alright but I think a light theme would be better

I'm trying to make a flask web app with logins for two different roles: vendors and customers (each have different attributes). I'm having a hell of a time figuring out what to do... I'm supposed to do it with mongodb atlas (mongoengine is what I'm currently using to interface) and Flask-Login or Flask-User, but I can't figure out how to really use it. I know how to do it with sessions, but I don't want to 😛 bc I think it'll be a bit more insecure. Any advice?

I’ve not used FlaskUser but checkout FlaskLogin + FlaskSecurity (which may be abandoned though I think there’s a fork).

perhaps a dumb question but i am adding a relationship to one of my entities that is one-to-one to the User auth model. However, I want this relationship to be ignored for admin users, how would that work?
when i tried and create a migration it is asking that my superuser had the relationship. in this case would i create two separate models. something like AppUser and AdminUser?

i think you can do without wtforms
but it's better when you learn how to use them, the form.validate_on_submit(): is very useful
you definetely can do without it, but using it is really simple
fickle fox
oh okay 
wild thunder
i'll get an snippet
<form method="POST" action="{{ url_for('site.login') }}">
{{ form.csrf_token }}
{{ wtf.form_field(form.username) }}
{{ wtf.form_field(form.password) }}
<input type="submit" value="submit" class="btn btn-dark">
</form>
if you have flask-bootstrap, you can use this:
{% import "bootstrap/wtf.html" as wtf %}

it's to enforce security, "Cross-site request forgery"

working on a flask web server, I have a bunch of stuff for logging in that works, but at one point I reditrect the user to http://127.0.0.1:5000/accessdenied (testing rn), which looks like this:
@app.route('/accessdenied')
def access_denied():
return render_template('access_denied.html', home = url_for('login'))
however when I load that page, I immediately get redirected to the Not Found page
im very confused, anyone got any ideas?
and yes, access_denied.html is in my templates folder
and I know the other things in the templates folder are getting picked up because at one point I render a different page for the user and it works
muted grove
scratch all the previous stuff, I figured that out. I am now struggling with getting the flask app which is just running locally to be available externally, through port forwarding
the port forwarding is all working, and I got everything set up properly to where when I have the ap runnnig, I am able to use https://canyouseeme.org/ to confirm that the port is listening only when my app is running
however I am unable to connect it, even after turning off debug mode
actually, I managed to get it
rustic dragon
pls help
<img src="./myimg.png"> or <img src="/myimg.png"> or <img src="myimg.png"> ?

@rustic dragon it depends on its place so if its in the same directory(with the template file) you gotta use this <img src="myimg.png"> if its in a folder in the directory or not in the directory at all you gotta use this <img src="folder_path/myimg.png">
so in the second one you just put the folder path

Hey, I'm trying to build a server with flask and when I run it using the 'flask run' command in powershell it works. However, debug mode is off. When I use the 'set FLASK_ENV=development' command I get no errors and it seems to work. However when I 'flask run' the debugg mode is still set to off. How do I fix this?
feral minnow
@native tide ```python
if name == "main":
your_flask_object.run(debug=True)``` this should work
native tide
It's not working
feral minnow
@native tide Can i see you code?
native tide
feral minnow
ohh,when I said "your_flask_object" I meant "app" because its contain the Flask(__name__)
feral minnow
It worked?
native tide
yes
limber laurel
@feral minnow Yeah but I want to do that in my base remplate and one of the reasons why I want to do it is so I wouldnt need to return a object like that everytime I render a template
feral minnow
what is the object your trying to add?
limber laurel
application
I want to access app.url_map from my template
For my header so I cpuld loop through them without worrying if their names don't change
feral minnow
@limber laurel can you show me an example because im not sure im understaing?
@native tide try this https://pypi.org/project/Flask-Debug/
limber laurel
So lets say I have my base.html template, which includes the header elements
I want to loop in the html
{% for url in app.url_map.iter_obejct() %}
if url == current_url:
Dont render
Else render the button for the navigation bar
feral minnow
@native tide I think you have to put it if __name__ == "__main__": app.run(debug=True)
feral minnow
@limber laurel hmm,I can't think of anything,because when you want to render the template you're calling the template you want and it just make a copy for "base.html" I think.
@native tide So you have to put if __name__ == "__main__" after you done the work so like under every function
feral minnow
ohh
native tide
ok I found that the command is actually $env:FLASK_ENV = "development"
which is different then what the documentation gives me
but it works with that
feral minnow
nice, for me I just added debug=True and it worked but I don't know why it wasn't working like that with you
native tide
i don't know
I don't need the if statement at all
when I use this command
it works eithe rway
feral minnow
yeah I think this will work too but I add if __name__ == "__main__" because they say its a good pratice,I still don't understand the reason for that tho
quick cargo
@feral minnow Its because when you deploy it you dont want it triggering the app that way
it stops it getting started when another app call the file
feral minnow
oh so when another app that has this code if __name__ == "__main__ the first file will stop working
@native tide np
quick cargo
!d main
lavish prismBOT

@quick cargo I will try to understand more,thanks 😄

Guys I want to make an auto fit text,anyone know how to do it with html?
nvm,I just found the answer font-size:10vw
verbal obsidian
If anyone wonders what 10vw is, it's the view port units, in this case, view width
1 vw is 1% of the viewport width
feral minnow
I still have a problem
the list is not fitting
.manga-text > ul {
display: block;
margin: 0 auto;
text-align: left;
width: 40%;
font-size: 18px;
}
.manga-text > ul > li {
white-space: nowrap;
}```here's the css code
I can use font-size:wv but when i use its either too big or too small
verbal obsidian
could I have a picture of the actual thing?
verbal obsidian
Something is wrong then, it should resize.
Inspect the element and make sure that the font sized is in vw
feral minnow
no no im not using vw here
if you see the code above
here's how it looks like when im using vw
also im using font-size:1vw if I put more than 1 it will too big
verbal obsidian
make media querys with breakpoints
feral minnow
I actually don't know how,I don't work with css too much... can you tell me how?
verbal obsidian
basically a media query is a piece of css code that does this
if width/height is x
you set element properties
and breakpoints
are general width sizes where you usually make changes
like, phone width, tablet, computer screens..
You are probably better off reading about it here, https://www.w3schools.com/css/css_rwd_mediaqueries.asp

Yup I will have a look thx

When I read about celery best practices, I often see people saying to use db keys instead of actual objects. but this means the data in the db can be changed behind the scenes so it's fraught with race conditions. You could even have data changing between retries. It's even more puzzling because the same best practice blogs say that the tasks should be idempotent. Having all your arguments up front and constant is nessesary for idempotency since then you know you are indeed doing the same operation. Further, if you put data in the db and then look it up in the task then you have multiple writes. if you chain tasks then each one is hammering the db. it seems like this advise is completely backwards 100%.
patent cobalt
I'm not familiar with celery (disclaimer), but the articles I've just looked at mention two things:
- You can't very well share ORM objects tied to a database connection between different processes that each have their own connection
- The data may get stale in the meantime
To me, it sounds like it's mainly talking about another issue that the one you're facing: Let's say you're trying to send an email to a user, the user updates his email, then you want the freshest copy of the data instead of having lingering tasks that fall back to the stale data they copied "some long time ago".
At the same time, if stale data isn't your concern and you want to minimize the number of database reads/writes, maybe passing the actual data isn't as bad
blissful slate
I think part of the issue is that celery might use pickle which isn't particularly fast. and using complicated orm objects might make perf not great. and people who dont care might try to send a db cursor over the wire which will indeed fail. or even a query result which could be a stonking huge list.

Can someone suggest me a good book for learning Django or the documentation is sufficient?

This is by far the best series that is not "just do what i do" and explaines pretty good.
@earnest osprey Books are generally much better but I suggest you to check this out. Btw which level are you in like beginner or intermediate.
beginner
@native tide Are u also learning django?
yes
So how long have you been programming python
Bc if you are a 10 day coder even though you have learned all the things experience is important
two years or one year
OK
then ok i guess
😉
I am beginner to intermediate
ok
and idk why but the complexity that django has over flask makes it hella lot nicer to learn django if you ask me but the reason i asked is that a lot of beginners complete a tutorial series and without experience go straight into writing complex code. You gotta know the basics really well. That's a mistake that i did when i first started coding.
That's the thing that sets up the line between a professional devoloper and me. Maybe except modules we know the exact same thing but he can use it better. Its kinda like we have the same car but he is an f1 pilot and im the regular driver on the rode
