And create a model for each one.

frosty mauve
That's the gameplan (connecting them with other data as well)
queen bough
Right, need any other help with that?
frosty mauve
Let me see if this save works, I would be curious to see how you would do it but I feel confident in doing that if this save works
queen bough
Sure.
frosty mauve
saved, but pic didn't show up let me check something else
I think it is something with upload_to='/images'
The obj points to the /images but I didn't have image in there
So I need to just put all my images in there
queen bough
Where is upload_to? Is that in the ImageField definition in the model?
Surely you can simply change that?
frosty mauve
image = models.ImageField(upload_to='images/')
queen bough
Why isn't it media/?
Or is media reserved for the site images? I can't remember the distinction, exactly.
frosty mauve
No good reason, just trying to get this workign following an array of tutorials online
I guess I need to change my template now to fit media
frosty mauve
but I keep running into that same problem!
when I save it prefixes the url with media
and then the file path of image
image at /home/name/project/site/media/image.jpg
I set the newbook.image = path
when I type newbook.image.url I get media/home/name/project/site/media/image.jpg
queen bough
Hmm, this shouldn't be so diffcult. Let me quickly take a look.
frosty mauve
Appreciate it ❤️
queen bough
@frosty mauve Ah, see if this helps - he has a model with an ImageField too, https://medium.com/@ksarthak4ever/django-models-and-shell-8c48963d83a3

I need help with Flask. Im learning templates and im doing easy stuff. Someone can help me? Extends method of jinja doesn't work
Thats the app
app = Flask(__name__)
@app.route('/')
def index():
return render_template('base.html')```That is the base html file
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Homepage</title>
</head>
<body>
{% block body %}
{% endblock %}
</body>
</html>```@queen bough I think it's just a pathing issue, I will mull over this for a few more hours and let yyou know if I get it resolved 🙂
queen bough
@frosty mauve Sure, sorry I couldn't help any more.
toxic marten
And this is the derived.html
{% block body %}
<body>
<p>HELLO</p>
</body>
{% endblock %}```Thats pretty easy, but it doesnt work. Have i done some mistakes?
frosty mauve
@toxic marten Is it block body or block content?
frosty mauve
I have never seen body, just trying to help
frosty mauve
I am working with Django and I am using some includes, haven't messed with extends yet but all the blocks have been block content
toxic marten
ok
my book says body is for content of the body tag, and content is for user defined page content
so should i use content?
frosty mauve
wouldnt hurt to try it real quick
I am still trying to figure out these webapps too 😛
toxic marten
👍
Flask is my first backend framework that i use. At first, i wanted to start with django, but a lot people say me that is better if i start with flask, cause it is more simple
frosty mauve
I think I probably should have done that 😛
I heard the same
bottle-> flask -> django
toxic marten
Exactly

hi everyone! Hope someone can help. I'm making a practice project, it allows users to store their meds in a database and I'd like to add some sort of alarm or reminder (probably a notification, or email). I'm working with Django and I really don't know how to link the time selected with the notifications or email, or how to even add that functionality... Any guidance you could provide would be helpful.
proper hinge
You'd need to schedule a task to run in the future I imagine
I've not looked into how to do that with Django
However, Django 3.0 does support async AFAIK and generally it is possible to accomplish that with async, so that is one avenue to explore
Celery could also do this but it sounds like it may be overkill?

I have a django model that stores the date & time when an object is saved. How can I get the total saved in the lpast hour, day, seven days, month and year? I think I can use pandas to do this but it's kinda heavy. What's the best way to do this?
errant spindle
how do i make the labels go directly above the rectangles
so that there's no space between the label # and the rectangle
nimble epoch
@mighty herald can i see your models?
@errant spindle use bootstrap or put every input with its label in a separate <div>
errant spindle
whats bootstrap
nimble epoch
This is a kinda library
You can even put every input and its label in the separate <div>
<div>
<label>label1</label>
<input type=“text” />
</div>
<div>
<label>label2</label>
<input type=“number” />
</div>

Hey guys, I'm trying to understand urllib, and it feels like the simplest thing would be to request the active browser URL, and save it as a variable.. but the answers I got on stack didn't make much sense, or work when I tried to run them. Any tips?

Someone who is deflecting questions with "use bootstrap" shouldn't be throwing rtfm around
mighty herald
Good morning @nimble epoch heres a picture of my models
mighty herald
i have it but the user_login error is still showing up every now and again
nimble epoch
Can i see the whole error
mighty herald
its not showing up anymore. but it shows up sometimes
nimble epoch
Oh
mighty herald
On a different note i set up my schedule page and its functioning well except the same data is getting displayed on every users account even if im logged in diffferent accounts.
nimble epoch
You are not getting data from different user id probably
Does it show the whole data?
mighty herald
It shows every input i have made. So everything in the database im guessing. But heres my view for my schedule page
is it possibly because of line 26 where im query.all() ?
nimble epoch
Yeah you are adding whole data to dict
mighty herald
db.query.filter_by(current_user.id) ?
nimble epoch
Better use db.query.filter_by(user=current_user.id)
If im right because i haven’t practiced flask for months
mighty herald
It worked! Thanks a lot man 🙂
nimble epoch
Yw
mighty herald
Hey @nimble epoch if your still around, heres the error that i was talking about.
nimble epoch
Can you send the files that you are working whith because i cant find it like this
If possible
mighty herald
which files in specific?
nimble epoch
Your project
In a kind of cloud
Or sth
Line dropbox
Because i have never got this error
mighty herald
sure ill try dropbox

does anyone use Flask on Debian? I am having a hard time getting flask-sqlalchemy installed despite trying multiple things and searching for the error
jagged lark
Are you running it on a regular amd64 plateform, or on a arm device (like rpis)?
wintry lava
amd64
wintry lava
here are the steps: python3 -m venv env. source env/bin/activate; pip install flask; pip install flask-sqlalchemy
jagged lark
Can you try to update setuptools and pip?
jagged lark
And setuptools?
wintry lava
havent tried that yet. let me do so now
same error....it did update setuptools from 44.0.0 to Successfully installed setuptools-46.1.3
mighty herald
@nimble epoch how should i share you my files?
nimble epoch
There gotta be a share link
jagged lark
@wintry lava flask-sqlalchemy doesn't support 3.8 yet, the latest release is from Sep 24, 2019, before the release of 3.8 
wintry lava
ahh!
mighty herald
nimble epoch
Oh ok let me check
mighty herald
Thank you
wintry lava
@jagged lark did the same steps with python3.7 ...same error 😦
python3.7 -m venv ~/.venv/flask
python --version
Python 3.7.7
command: /home/abc123/.venv/flask/bin/python3.7 /home/abc123/.venv/flask/share/python-wheels/pep517-0.7.0-py2.py3-none-any.whl/pep517/_in_process.py get_requires_for_build_wheel /tmp/tmpehh2wnwl
actually let me update setuptools here too
nah..same problem
jagged lark
I don't know the solution sorry, but you should try to reach the developers https://github.com/pallets/flask-sqlalchemy/issues
wintry lava
i guess it doesnt buildSQLAlchemy
will do. Thanks for looking!
@jagged lark found something relevant: https://github.com/sqlalchemy/sqlalchemy/issues/5207
yes it worked with : pip install --no-use-pep517 sqlalchemy and then pip install flask-sqlalchemy

I cant run your project
No i mean the error
I have you files but the error that it gives you

I was looking for a file name
Sorry man thats a little complicated i still dont know why you get that error
mighty herald
Ill keep doing my research, but i appreciate your time man
nimble epoch
I really hope youll find it
mighty herald
Thankyou ill let you know when i do
nimble epoch
@mighty herald
I got sth but not sure
@login_manager.user_loader
def load_user(id):
return User.query.filter_by(user_id=id).first()
Of course be sure add this after app initialization
mighty herald
in my models file?
nimble epoch
Yeah
You have got your project so complicated and i guess that the orders are not correct
mighty herald
it initially got rid of the user loader issue but i got this
nimble epoch
Rhisnis because you dont have User and user_id
You gotta replace them base on you database
You add it like this
@login_manager.user_loader
def load_user(user_id):
return User.query.get(id=user_id).first()
If it didnt work
Use
@login_manager.user_loader
def load_user(user_id):
return User.query.get(user_id).first()
Whats the result?
mighty herald
I got it to work by deleting from flask import request that I wasn't using. Looks like it was missing a request_loader because of that.
mighty herald
Yeah! Except knowing this issue that it keeps coming back im not so sure. lol
nimble epoch
You can fix that too😉
mighty herald

make sure to ask your actual question with any issues and code you have @modest elk it makes people more inclined to help

from flask import Flask, render_template, json
import requests, json
app = Flask(name)
@app.route('/')
def index():
r = requests.get('https://coronavirus-19-api.herokuapp.com/all')
data = r.json()
data = json.dumps(data, indent=2)
deaths = data['deaths']
return render_template('index.html')
if name == "main":
app.run(debug=True)
So i am trying to build a flask web app
to fetch this json api, and show it to my app
But i am finding it difficult
How i show it to the index.html
In js i would do for example {data.deaths}
rigid laurel
data = r.json()
data = json.dumps(data, indent=2)
deaths = data['deaths']
This bit isn't right.
just ditch the second line
and it should work how you expect
dumps is dumping the json to a string. loads is loading a json form a string, but thats called by r.json(), so you don't need to do it
still briar
You should also pass varibles into the render call. For instance render_template('index.html', foo=42), or deaths in your case.
rigid laurel
yeah, thats how you want to show it in the template
you can pass the whole dict
you can do return render_template('index.html', data=data) then access data inside html by doing {{ data.deaths }}
modest elk
File "C:\Users\Irdi\Desktop\flask\app.py", line 12, in index
deaths = data['deaths']
TypeError: string indices must be integers
I get this error
i dunno why
rigid laurel
I explained why above
dumps is dumping the json to a string. loads is loading a json from a string, but thats called by r.json(), so you don't need to do it you want a dictionary, not a string. and r.json() returns a dictionary

modest elk
dumps is dumping the json to a string. loads is loading a json from a string, but thats called by r.json(), so you don't need to do ityou want a dictionary, not a string. and r.json() returns a dictionary
@rigid laurel When i remove deaths = data['deaths'] it loads the app but not the number of deaths. when i leave the line than it shows the error, i will try my best
rigid laurel
Let me try and make sure I understand your problem. You're trying to get the number of deaths from the json into the template right?
rigid laurel
If so, you need to pass the dictionary result of r.json() into the template. For your case you can do that with something like
def index():
r = requests.get('https://coronavirus-19-api.herokuapp.com/all%27')
data = r.json()
return render_template('index.html', data=data)
Then inside the template do
<div class="deaths">
{{data.deaths}}
</div>```Does that still give you an error @modest elk ?
modest elk
No error but it's blank
rigid laurel
Can you paste your template here?
modest elk
I know that i disturbed you i am sorry

Finally i got it
thank you so much @rigid laurel

You might also want to cache that if you are pushing this to public? 🙂

Guys I wanna ask you... So im trying to make a mp3 song downloader using flask but I don't know how i can upload the files to the users after its converted?
modest elk
You might also want to cache that if you are pushing this to public? 🙂
@pure token First time i did it with Svelte JS and it was easy, now that Charlie explained that to me i find it easier to do it in Flask too
Cache with redis?
rigid laurel
So you want the user to be able to click a button and download an MP3 @feral minnow ?
or the user uploads a file, you process it, and they get the file back?
feral minnow
I want the user to click a button and download the files
pure token
@modest elk at least make a function with a cache decorator or something that stores the value for a short duration so it does't do http request for every single page visit
modest elk

I tried <a href="{{filePath}}" download>Download File</a> but it didn't work
modest elk
For example update data every 5 min
rigid laurel
https://flask.palletsprojects.com/en/1.1.x/api/#flask.send_file you want to use something like this @feral minnow

This is my code
But it always leaves this bit of space on the right of the grid, why is that?I think you can just do return send_file('path_to_your_file.mp3') or similar
might need to set as_attachment to True
feral minnow
oh
I will try it thx
@rigid laurel i tried send_file but its playing the video its instead of downloading it
rigid laurel
I think thats why you want as_attachment=True
feral minnow
oh
rigid laurel
I haven't actually used this myself
feral minnow
I have to put it after the file name?
rigid laurel
return send_file('path_to_your_file.mp3', as_attachment=True)
should be that
hopefully
rigid laurel
you can also set a filename with return send_file('path_to_your_file.mp3', as_attachment=True, attachment_filename="magic.mp3")
feral minnow
You mean that when it download the file it will download it with this name?
rigid laurel
yeah
feral minnow
nice...Thanks again you really helped me

Hi guys!!! I am trying to find some help with this issue: I am usind Djangos paginator and when i click Next, instead of having the second page I receive my 'else' code
here my view and template:
native root
Your code does not make sure the q variable in the url persists through a next-page click
Because of that it becomes none, and you see what you're seeing. Your next page links should include the q value of the current page to make sure it persists appropriately

Guys anyone know how to center card from bootstrap
tried everything but nothing work????
nimble epoch
Try:
class=“row justify-content-center”
nimble epoch
Yw
queen bough
It's also very dependent on your use-case, and thus difficult to explain out of context.
meager glen
How can I center a button that is in a bootstrap card
nimble epoch
Try:
class=“row justify-content-center”
meager glen
That didnt work
queen bough
@nimble epoch Yup. Start with functions and refactor to classes if/when you need them.
meager glen
I centered the card with that but the button wont mov
nimble epoch
Put your button in a <div> and use that class in the <div>
Worked?
You can even use html <center> tag
nimble epoch
Really?
Sometimes i think bootstrap doesn’t match with html and css
Even with itself
@queen bough i dont think that class based is useful, is it?
meager glen
queen bough
It is, very. When you want to connect it to a model then they are.
I can't remember all the reasons off the top of my head, but there's definitely a place for them.
Function-based are a lot simpler though.
nimble epoch
But you can use models in function based too
feral minnow
@nimble epoch its a photo of the website he's trying to make
He's trying to center the login button
nimble epoch
Add that class to your base div that has rounded the form
If didn’t get me send me the file to help
If got me so everything is alright
nimble epoch
Can i see the code?
feral minnow
the problem is he's offline now
nimble epoch
Because i cant tell you where i meant
Oohh
You see the login form with the button?
feral minnow
yes
nimble epoch
Yeah
feral minnow
I remember that he tried that already but it didn't work
nimble epoch
Surround your whole code after body tag with a div and and add that again to that div
This will probably work
nimble epoch
Thats great

i'm implementing a flask restful backend for a mithriljs webapp and trying to do auth. everyone says to use jwt, but is that a really a better solution than just flask-session?
it seems like a pain to have to mess with refresh tokens and local storage to get session to persist
native tide
like regular acco0unt auth ?
stable notch
yeah, normal accounts
jwt sounds like the better option, but i'm wondering if sessions that persist like normal session cookies are possible
fresh dock
@stable notch yes flask implements a cryptographically signed session cookie
stable notch
@fresh dock but would this be the correct use case for it? i'm not sure whether to use it or jwt plus refresh tokens
stable notch
it's acting as the backend for a single page app, so cookies are implemented

So, I'm building a local hosted (on a raspberry pi) Django web server that will have a landing with different buttons on it, similar to a bookmarks or quick launch page, and the other app will be a page that controls an LED strip attached to my raspberry pi. I don't believe either of these apps require much at all, if anything, to do with database storage besides maybe for the superuser account (is that even stored in the database?). For now, can I basically skip over messing heavily with Models and the database stuff?

tired root
What do you need an explantion for?
An IP address has a host part and a net part
The net part comes first and defines the network
the host part defines the number for that client
which part of the number is which, is defined by the subnet mask
@white pewter
tired root
Random?
white pewter
Can i take 21 bit net id and 11 bit host id
tired root
you can, if the selected subnet allows it
tired root
10.0.0.0/8 is a subnet
It's a private ip subnet
You can take this, and divide it into smaller chunks
So, 10.0.0.0/21 would be legal
white pewter
No i m newbie and this is from a book
tired root
You've never set the IP on your computer?
white pewter
Ifconfig shows my ip
tired root
yes and it also shows your subnet mask
That is the part that defines how many bits are for the network and how many bits are for the hosts
tired root
So an IP has 32 bits
white pewter
So what decides that net id is 20 bit and host id 12 bit
tired root
You
tired root
forget the internet for a seconds, that is too complicated
lets stick with private IPs
white pewter
Ok
white pewter
Ok
tired root
It defines the network with the number 192.168.0.0
white pewter
Ok
tired root
Because netID is an IP and i need a broadcast IP which is always the last IP
white pewter
Oh
tired root
So, how many bits do I need for 10 IP?
3 is too little
so I need 4
32 bits - 4 bits = 28
192.168.0.0/28 = 14 max hosts
white pewter
Well i will complete the book then again come here , its little complicated
tired root
You are on linux right?

@white pewter That subnet can contain 62 hosts, the max number is 255, so 255.255.255.192 can contain 4 networks
white pewter
How did u know 62 host it canhave
tired root
Because 256/64 is 4
tired root
Remember, 62 hosts, + 1 ID + 1 Broadcast = 64
tired root
255.255.255.192 are 26 bits
255.255.255 = 24
192 = 128 + 64 = 2 bits
Because bits order is 128 64 32 16 8 4 2 1
white pewter
Fucking bits
tired root
it all comes down to the bitwise addition
white pewter
Fuck binary
tired root
TO subnet, you are splitting a number in half
Basically
so you need to go down to the bit level
white pewter
Ok
tired root
Take a piece of paper, make a table with the bits
Then insert your desired netmask into it
calculate the number
Once you get the hang of that, you'll be subnetting without even doing math
tired root
It's the same
white pewter
Then use subnet mask for determining net id
white pewter
Yes i had confusion in Cidr and submet mask but now i m not
I feel easy
Also i learnt how to determine net id from cidr
white pewter
I dont know what is broadcast or broadcast id
tired root
Broadcast is the last IP in the subnet
That is really all it is
What it is for is irrelevant for now
So, got a net with 192.168.0.0/16
ID is 192.168.0.0
Broadcast is 192.168.255.255

Hi, I want to ask why I got the 'refused to connect' message on web? I'm using django and I've set with 'xframe_options_exempt'. I can view the file with
<p>Open a PDF file <a href= {{ content.file.url }} >example</a>.</p>
after click the button. but not able to view directly with
<iframe id="iframepdf" src= {{ content.file.url }} width="100%" height="500px"></iframe>
Do I have any wrong setting? Thanks

native tide
need help error is too short Its not helping
gilded dragon
It looks like it's not properly finding an associated view or URL path, maybe
native tide
@gilded dragon yep but I'm not getting it can you help?
gilded dragon
No, I am not good enough at Django yet to help you adequately. I'm just helping how I can. It looks like the URL you're requesting is kind of... Weird? Maybe check out what's going on there? It's possible the link you're requesting from your server is not in your urlconfs so maybe fix that or see if it's correct
tired root
@native tide %5E is ^ , so there is somewhere an extranious ^ in your code
gilded dragon
Probably in the http request he's making, yes?
tired root
in the url...
gilded dragon
Right, I know
But where would that ^ be, code-wise? In the request he's putting to the server, yes? He's "asking" to go to ^Like/$ somewhere
native tide
this is url path ```
path(r'^like/$', views.like_post, name='like_post'),
Theres your problem
native tide
and If I change it it gives this
tired root
The ^ is still in your url
gilded dragon
Yep
tired root
do you not see that your url is malformed?
native tide
how do I solve it?
gilded dragon
Also media has a ^ in it too, not sure what that's about but you might want to fix it now or resolve why it's there in the first place
The thing you're requesting with is asking for a url with ^ in it
native tide
I remove ^ but it didn't work
gilded dragon
Perhaps a button?
Remove the ^ from the request that the button or whatever it is you're trying to send to the server
tired root
I wonder why you are trying to regex a url anyway?
An Url is not a suggestion, it is hardcoded
tired root
@gilded dragon The running commentary is really not necessary
native tide
I'm trying to make a like button Its working but whenever I press it it give this error working means I can see likes in admin page
tired root
ok, but why the ^like/$ as if you are regexing it?
Just do /like/postid/ done
Or the id of whatever is getting liked
Anyway, your issue is that the url is malformed due to the ^ and I don't see your code, so you gotta somehow fix that. Your routes seem to have a /like/ path, maybe adjust to what I suggested or simple remove the ^ and figure it out from there

Hi, how can i download a file to a flask server?
I would like to download an online video to the flask webserver then send it to the user. Ik know how to send the file just not how to download it specifically to the sever.
tired root
Use a request
native tide
It didn't work dude
tired root
You didn't what?
native tide
oop
native tide
look at this ```
Page not found (404)
Request Method: POST
Request URL: http://127.0.0.1:8000/like/postid
Using the URLconf defined in django_project.urls, Django tried these URL patterns, in this order:
admin/
register/ [name='register']
profile/ [name='profile']
login/ [name='login']
logout/ [name='logout']
password-reset/ [name='password_reset']
password-rest/done/ [name='password_reset_done']
password-reset-confirm/<uidb64>/<token> [name='password_reset_confirm']
password-reset-complete/ [name='password_reset_complete']
[name='blog-home']
user/str:username [name='user-posts']
post/int:pk/ [name='post-detail']
post/new/ [name='post-create']
post/int:pk/update/ [name='post-update']
post/int:pk/delete/ [name='post-delete']
announcements/ [name='blog-announcements']
about/ [name='blog-about']
^like/$ [name='like_post'] #This line here
^media/(?P<path>.*)$
ok, but now the ^ is gone from the url, so thats good
postid was actually a sample variable to denote the id of whatever post or image you want to be liked
it wasn't literally
I was a suggestion how to structure this
native tide
ik but I tried it cuz I'm pissed off and nothing is in my mind
tired root
The route would be something like /like/<int:postid>
Then use that post id in your code to increase the like count
however you do that in your project

def like_post(request):
post = get_object_or_404(Post, id=request.POST['post_id'])
post.likes.add(request.user) #This one is line 50
return HttpResponseRedirect(post.get_absolute_url())
make sure you write it in the right way
maybe post_like or post_likes
I don't anything about django but maybe this will work
native tide
this is the url path So ...
path(r'like/', views.like_post, name='like_post'),
``` like_post maybe?I'm trying to make a like button for my blog site

Essentially Im practicing while creating a team builder based on players attack and defense stats; and the return_template call is not being passed when I post to the /teams form
`
from flask import Flask, render_template, request
import csv
import random
app = Flask(name)
app.config["DEBUG"] = True
file = "XXXXXXX"
allPlayersData = []
with open(file, 'r') as data:
csv_data = csv.DictReader(data)
for row in csv_data:
allPlayersData.append(dict(row))
shownPlayers = []
for item in allPlayersData:
shownPlayers.append(item['name'])
print(shownPlayers)
def searchPlayer(name):
for p in allPlayersData:
if p['name'] == name:
return p
def buildTeams(playersList):
selectedPlayers = []
for item in playersList:
playerData = searchPlayer(item)
selectedPlayers.append(playerData)
teamAtkDelta = 4
teamDefDelta = 4
team1 = []
team2 = []
while teamAtkDelta >= 4 or teamDefDelta >= 4:
sampling = random.sample(selectedPlayers, 16)
team1 = sampling[0:8]
team2 = sampling[8:16]
team1Defense = sum(int(item['defense']) for item in team1)
team1Attack = sum(int(item['attack']) for item in team1)
team2Defense = sum(int(item['defense']) for item in team2)
team2Attack = sum(int(item['attack']) for item in team2)
teamDefDelta = abs(team1Defense - team2Defense)
teamAtkDelta = abs(team1Attack - team2Attack)
return render_template('teams.html', team1 = team1, team2 = team2)
@app.route('/', methods=['GET', 'POST'])
def availablePlayers():
return render_template('players.html', shownPlayers = shownPlayers)
@app.route('/teams', methods=['POST'])
def buildDamnTeams():
selectedPlayers = request.form.getlist('selectedPlayers')
if len(selectedPlayers) >= 16:
buildTeams(selectedPlayers)
else:
return "missing players, should be 16"
`
everyhing is working fine except that call to buildTeams() on the /teams call on POST
TypeError: The view function did not return a valid response. The function either returned None or ended without a return statement.
vagrant adder
it does that when you select 16 or more players?
foggy narwhal
correct, when you select at least 16
vagrant adder
okay i found a problem
foggy narwhal
been reading and probably has somehing to do that the render_template should always have app context
could that be the issue?
vagrant adder
so when you select at least 16, you call function but never return anything from route functions
foggy narwhal
but the buildTeam function returns render_template and stuff, right?
vagrant adder
your buildTeams returns already rendered html and such, but it returns to route level, not outside it
i would do like this:
- make that buildTime only returns teams
so it ends in return [team1, team2]
and in your route:
if len(selectedPlayers) >= 16:
team1, team2 = buildTeams(selectedPlayers)
return render_template("teams.html", team1=team1, team2=team2)
else:
return "missing players, should be 16"

Is there some fundamental difference between serving a static image, and using send_file() to return an image?
Ideally I would not like to store a bunch of static images, but generate them dynamically on the fly (specifically using this: https://github.com/kebu/py-avataaars, combining a few svgs to render a png). I've set up an endpoint to send_file(image_bytes, mimetype), and it appears its working as expected when testing in a browser, but for some reason a mobile sdk that I am using it doesn't understand the image format.
If I curl my same endpoint to download an image, and serve that as a static file the mobile sdk understands the image as expected.
I feel like I am missing out on a tiny detail. Ideally I would prefer not having to generate some static file for every combination of avatar (very large amount), but generate them as needed.
quasi ridge
sounds like one of the response headers differs
see what headers your server sends in both cases: send_file, and static file
little steppe
gonna try that now, thanks for the response!
looks like the content-length isn't being sent with send_file() since I'm not passing a filename, time to do some digging
little steppe
hmmm, it appears extending a flask restplus Resource for the endpoint was somehow causing problems. I attached the endpoint directly to the app instead of extending a Resource and it looks like its working now, thanks again

@turbid glen Because you can only apply one animation to one element at a time with css

both of them work at the same time, i mean

yea
tired root
Also does not work in Firefox
tired root
Because you can only apply one transform at a time
And if you do it at once,the result would be moving in an angle
Because the matrix didn't get reset between
turbid glen
erm so can we write like this transform: rotate(xx), translate(xx,xx)
combine them together
tired root
As I said, it would be moving in an angle
If you'd do something like this in a game, you'd need to reset the modelview matrix in between rotation and translation
The same principle applies here
BUt you can't do that, and which is why I said only one animation per element
the background-color isn't such an animation
turbid glen
ok then

it's a simple property

Im working with Flask, and i discovered (with miguel grimberg course) that there is a dedicated extension for bootstrap (pip install flask-bootstrap). This extension will add some bootstrap folder and files in templates folder. But the problem is that i can use only bootstrap 3, because the extension is based on this version. Instead i want to use bootstrap 4. I found another extension (pip install Flask-Bootstrap4), but it doesn't create any folder, files, etc in templates files. It should add some files used by the extension, but it doesn't. I dont understand
Does someone use bootstrap 4 with flask? If yes, can you explain me a little bit, in general, how bootstrap and flask work together
toxic marten
Yes, ive done that, the problem is that flask-bootstrap extension has some features (macros) that are stored in some files. But there no files
vagrant adder
flask has templating engine that interacts with templates
flask bootstrap interacts with templating engine to give you more css (in a nutshell)
toxic marten
Yes. But im not referring to that. Flask-bootstrap has some features (macros), for example render_field(), render_form(), render_nav_item(), etc that are stored in bootstrap/form.html
But there no files. Theres no bootstrap folder. The problem is this
However i dont understand at first if flask-bootstrap is the version 3 or 4 of bootstrap. Documentation says that is version 3. A lot of tutorial says that is version 3, because all of this tutorial are old (most are old 3 years ago or more). But now for example i found this doc that says it is bootstrap version 4. Im really confused

I am looking in Django for an elegant way to destroy all user related active sessions. Preferably maybe I overlooked to do it in Django way? Currently I am using password_change from django.contrib.auth to change password and in addition after that I would like to destroy all the user sessions for security reason. I was shocked that Django default mechanism is not doing that.

Hey, I'm trying to get into webautomation with python but I'm running into this problem where if I use the element of i.e a searchbox, and try to execute a method "send_keys" to it, the autocompletion doesn't register that for me.
The weird thing is that there are 0 error pop ups after I - manually - write out the whole command. However, it consistently executes a "element not interactable" error when I try to either click a button or send information.
When I try to instead use it as a script, it suddenly works fine and I can click on buttons as normal. Why does this happen?

@queen bough thanks, I stumbled upon the stackoverflow entry and wanted to follow it however I don't know how to integrate it with change_password ready form/view
queen bough
@cunning prairie When change_password occurs successfully then call delete_all_unexpired_sessions_for_user. Should be that simple.
But, as I said, I've not done this before.
cunning prairie
In this case it seems that I would need to mess with django.contrib.auth.* files which I wanted to avoid. As I see password_change works pretty automatically, template is just {{ form.as_p }} and view with form comes from the lib
queen bough
Why would it mess with the contrib.auth files?
cunning prairie
How could I attach the code without modifying django.contrib.auth.* files?
To use password_change, I did only {% url 'password_change' %} in my html file, {{ form.as_p }} as template to render the form and path('account/', include('django.contrib.auth.urls')), to attach urls from the lib
that's all my code, I am not sure from where to execute delete_all_unexpired_sessions_for_user
queen bough
Ah right. You might have to create a view that extends contrib.auth (perhaps by passing stuff to it), though honestly I don't really know.
https://docs.djangoproject.com/en/3.0/topics/auth/default/#django.contrib.auth.views.LoginView - might also help.
cunning prairie
I'll try to do it, thanks for a direction.

Like run() and await start().

A download is the same thing as downloading a web page

If Heroku allows that, idk, I don't use that service

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

Django question real quick. Setting up a simple website/webserver. Should my apps be initiated in the same directory as my "base" project files (so like, settings.py, wsgi.py, etc.) or above a directory, where manage.py is? I'm still kind of confused on that.
tired root
apps initiated? what?
gilded dragon
Like when you start an app.
tired root
You don't start an app
gilded dragon
It creates the directory with the app's files.
tired root
The webserver runs the python code
gilded dragon
The command is "startapp". So what else do you want me to call it?
When an app is first created, I'm trying to figure out where in the directory hierarchy it should be created/initiated in.
Right now, I have it in the same directory as my "base project app", or whatever that's called. So the new app's directory is in the same directory as the base app, and manage.py.
tired root
When you run it locally, you launch manage.py
from the same directory
On a webserver, things are different
gilded dragon
I don't think that's relevant to the question
tired root
ok then

I'm just looking to get my directory hierarchy set up correctly right now

I have a simple web application that was built with flask and sqlite3. I have form, user can enter a name of grocery and quantity and it will get inserted into my database and on to list of grocery items. The problem I have is how to delete an item and how to implement this. I'm new to flask and having a hard to figuring this out
rustic pebble
Well deleting an item is probably equal to deleting a row
Model.query.filter_by(name=target_name).delete()
Model is your db model, target_name and name are just place holders they can be whatever the columns you have are and delete is self-explained

I created new Django project with PyCharm how I can login now into Admin?
toxic marten
Does someone use flask-wtf or flask-bootstrap?
tired root
@toxic marten No to flask-wtf, because writing my forms is faster in HTML than that library. No to flask-bootstrap, because I am not going to burden my users with megabytes of code for something I can do by hand.
toxic marten
Ok ok. I just only want to ask about csrf protection
Without flask-wtf, how can i do this protection?
tired root
import uuid
def generate_random_string():
return str(uuid.uuid4())
That is one way
but just read up on it, explaining the whole process is too much for a chat
one important thing: Always use POST, never anything else
Also make sure your site is protected against XSS attacks
Thinking about it, you could also generate a session secret and encrypt the random string with that
So you can decrypt it when it comes back and make sure it is legit
toxic marten
Thank you

I really need help with memcache 😦
Can someone who has the time and the patience and the courage pm me to mentor me on how to use caching with the Flask app that I'm coding? Tyvm in advance!
tired root
WE are not doing dm help
also, this belongs in #414737889352744971
And I am giving you this free warning: open memcache servers are dangerous
make sure you know what you are doing
orchid current
@tired root thanks and I'm sorry for the wrongdoing on my part!

How can i disable browser default alert? Here there are at the same moment, the chrome alert and my custom alert that inform the user that must fill the form (im working backend side)
I want that only my custom alert is displayed
toxic marten
I didnt use required property, but it is rendered in the page because i use DateRequired()
name = StringField('Username', [DataRequired()])
email = StringField('Email', [DataRequired(), Email()])
submit = SubmitField('Submit')```

Does anyone know how to get the Recaptcha from a website, solve it somewhere else, then use post the solution in the original website
Like how 2Captcha and anti-Captcha work

Django models question -- i've got a model (Cart, as in shopping) which has a ManyToManyField to a Product, using a CartItem as the intermediary model. in the process of building a feature, I've discovered there are some number of Cart instances whose ManyToManyField appears empty (i.e., no relations to Product instances), but for whom cart.cartitem_set (the intermediary relation) is not empty. Trying to decide how much to care about this before digging into how that happened and whether it needs to be fixed...

@rustic pebble I don't understand how I can implement it to my HTML
rustic pebble
You will do that on the server-side of things. usually that means app.py
kindred glacier
@rustic pebble The way I add an item is I use request.form['form_name'] and add that to the sql query placeholder.
but not sure how to do that with delete
How does my app know which item I want to delete?
rustic pebble
You need to create a model
After that you can use an identifier, it can be w/e u want to be able to choose what row you want to deelte

Does Flask have a way to save a session ID in the client?
native tide
@toxic marten the pop up is an HTML5 feature you added a DataRequired() validator to you form which adds the required field
@cosmic lantern yes flask can manage sessions. in the session variable or you can use flask-session and let it handle the sessions for you
cosmic lantern
oh, so flask-session just simplifies this?
toxic marten
@toxic marten the pop up is an HTML5 feature you added a DataRequired() validator to you form which adds the required field
@native tide Ok thank you @native tide . So i dont have to use required
But how can i implement the feature that input must be filled
native tide
yes flask-sessions is built on top of the session it makes it easier to manage user sessions the docs are also pretty good
toxic marten
If i dont use DataRequired(), will i use a rules created by me?
cosmic lantern
Do I understand it right, that sessions can store a session ID which can be used to authenticate API calls, so that the user doesn't have to log in again every time they visit my site?
native tide
@toxic marten if your field is required then add DataRequired
@cosmic lantern the session is a dictionary that has a csrf token added to it by the flask api apart from that you can pretty much add anything you want. user settings/ username etc
cosmic lantern
well I have a DB on the server that stores that SessionID along with a user ID that identifies a user. The client should only have that session ID and sends that along with a request every time it contacts the server
native tide
but i highly recommend using Flask-session coz you can get current user by defining a user schema that the Flask-session can use
so youre generating a sessionID for the user yourself?
cosmic lantern
can I store the corresponding user ID in Flask-Session?
no, currently not as I haven't implemented that yet
but I plan to
native tide
yes you can store it in the flasksession
cosmic lantern
since I want, as i said, to store a corresponding user ID for that session ID in my DB
okay
native tide
you can store and entire user object in the session
toxic marten
@native tide the problem is that i want that user must fill the input, but i dont want to use the default browser alert, generated by required. So, if use DateRequired(), it will render with required feature. I want to create a custom alert, for example the bootstrap alert that inform users to fill to fill the form. But if i dont use required and DateRequired(), what should i do?
Sorry for my bad english
cosmic lantern
flask session doesn't seem very popular 🤔
toxic marten
I mean this
native tide
@toxic marten yes you can add that too
cosmic lantern
but what are the advantages of using flask session if I am storing the session ID in my db anyways?
native tide
but if you submit a form without any data in it the required alert will pop up
@cosmic lantern then you dont have to waste time querying the DB
the session object also persists which means once the user closes the browser and logs back in you dont have to redirect them to the login page.
cosmic lantern
is that the right package?

toxic marten
Oops, i dont mean alert, i say a bullshit. I mean valid-feedback and invalid-feedback classes
native tide
@cosmic lantern https://pythonhosted.org/Flask-Session/
toxic marten
@toxic marten yes you can add that too
@native tide Yes ok. But i dont understand, sorry its first time that i try custom required
cosmic lantern
okay, thanks!
native tide
@toxic marten the required attribute basically prevents you from submitting an empty form
toxic marten
Yes i understood that
Im not very good with english, so maybe i dont ask you the question very well
But the problem is:
I want that user fill the input, BUT i dont want to render default browser alert, instead i want to do something like with bootstrap, i mean a text under the the input that says if input is ok or not. But if i cant use required and DataRequired(), how can i say to flask that the form must be filled. Because if i cant use DateRequired() what should i use?
@native tide I tried to write the best possible in English
native tide
you should use DataRequired(). once the user has submitted the form you should check if the form is valid by calling form.validate_on_submit()
then if there are any errors you can then send the form object to the template where you render your custom error
cosmic lantern
well, what should I use as the session ID? is it fine to just use a randomly generated string?
native tide
whats the users primary key?
cosmic lantern
it's a user ID (also the _id of the user in my mongodb DB)
or what do you mean by "key"?
native tide
the _id should be fine
cosmic lantern
but I shouldn't just store the password and the username in the session, should i?
