@heady thorn There are definitely flask/react frameworks oriented around charting/graphing. But if you're building things yourself, I'd reccomend checking out FastAPI
It seems very nice for this sort of thing
heady thorn
Thanks @rigid laurel awsome. So flask +fastapi +Vue is ok?
rigid laurel
No, just FastAPI+Vue should be fine
FastAPI and Flask are doing the same thing
FastAPI is sorta a nicer version of Flask if you're only doing Rest
which I assume you are with Vue right?
heady thorn
I haven't looked at integration with backend. I kinda figured flask would provide API framework
And I'd just suck it into Vue
If that makes sense :)
rigid laurel
Yeah, both Flask and FastAPI can do rest-APIs, just FastAPI is a bit nicer for it IMO
heady thorn
Great thanks v much for the recommendation. Hey, whilst I got ya...
Is python really awsome for the maths/datascience stuff?
Everyone says it is sooo... Yeah prob makes sense to use it as the backend for a data project.
rigid laurel
I've used the datasciencey stuff a little myself - and I don't mind it. But the way you use datascience stuff is quite different to how you use normal Python
I've not used R or anything similar, so I can't provide a comparison
heady thorn
Nice. I might check out jupyter notebooks too I hear also good
Right thanks Charlie. And thanks for the warm welcome to the community 😝
rigid laurel
Jupyter notebooks are the one thing I don't get. Maybe if you're demoing something to non-tech people, but for the most part I just find them irritating. But good luck with your Python adventures

Hi guys im using flask. Is it possible to use uploaded file without saving it ? For example recieve a photo then read characters from it (ocr) and send back those characters; I dont want to save the image.
quasi ridge
I suppose you could create an endpoint that just returns those characters in the response to the POST or PUT
but of course the photo would need to be somewhere in order to do OCR. Maybe just memory
broken oasis
@app.route('/', methods=['POST']) def upload_file(): photo = request.files['file'] oc = ocr(photo) return jsonify(oc)
gives error: im = cv2.imread(img) SystemError: <built-in function imread> returned NULL without setting an error
quasi ridge
sorry, I have no idea what "imread" is or how it works
quasi ridge
it looks like that function requires a file
which would answer your original question.
it also looks like that guide was written very sloppily, so I wouldn't put too much faith in it
broken oasis
So i guess i will stick to saving then deleting it after ocr...
quasi ridge
you might even use the "tempfile" library
broken oasis
I have this server deployed to aws elb and the ocr results are different than when i run it through aws and through localhost. Its 100% the same code but results from aws are much worse, is it possible that files are getting compressed when uploaded to aws? I haven't set anything to do that
broken oasis
its a service provided by amazon
used to host servers etc
idk how accurate my explanation is but i think thats enough
Amazon Elastic beanstalk
quasi ridge
well, I still don't know why you're seeing that difference.

I am using this:
def registerhandler(username, password):
pw = generate_password_hash(password)
print(pw)
print(check_password_hash(pw, password))
ins = users.insert().values(
username=username,
password=pw
)
connection.execute(ins)
return
To register users
And this for login
def loginhandler(User):
headers = {'alg': 'RS256'}
payload = {'username': str(User.username), 'iat': time.now()}
key = read_file('privateKey.pem')
search = session.query(users).filter_by(username=User.username).first()
print(check_password_hash(str(search[1]), str(User.password)))
if not search and check_password_hash(search[1], User.password):
print('Wrong credentials')
return None
elif search and check_password_hash(search[1], User.password):
print('User {} has been found'.format(search[0]))
token = jwt.encode(headers, payload, key).decode('utf-8')
print(token)
return token
print(check_password_hash(str(search[1]), str(User.password)))
It always returns false, even though search[1] returns the hash key from the database which was inserted using registerhandler()
and the User.password is the pw used by the user to signin
I cant get it to return True

@quasi ridge i figured it out, i forgot to download some additional data to the ocr program on the server, that i had on my local machine

Hello
I have a class with a variable self.passwords
after populating the passwords and having a route return the passwords, every few requests properly return the passwords but occasionaly one request doesnt and it returns []
here's a video example, im constantly refreshing (might not be able to tell) and at the end, data is [] but then goes back to being ["testpassword", "testpassword1"]
anyone know why this is happening and how to fix it
https://stackoverflow.com/questions/60470810/class-variable-returning-incorrectly-python-flask
here's the stackoverflow i posted, more detailed
tired root
What is manager.passwords?
From what you have said on SO, you are not using a DB
therefore, probably no proper encryption
Please explain what you are doing here
because it sounds like those 10k people will have a very bad awakening
@quartz lily
quartz lily
well
tired root
Just to let you know, I fully concur with what has been said on SO. Use a database
quartz lily
it's just something in a class
the problem is if I use a db it's so many reads to it
cause I have to constantly keep reading to the db
tired root
so?
that is what databases are there for
Also, with caching you can minimize all that
tired root
if you are managing the servers yourself, add nginx as a reverse proxy and use apache as app server with mod_wsgi
then an extra database server
But anyway, serving a website to 10k people a second is no trivial task
So, what is this manager?
how do you store passwords?
quartz lily
well it's for restocking my product
and I do have it in my database
a restock model which has a password, copies amount, and an IP from the checkout
but I use the manager class for handling all the restocks
tired root
A http request works this way: The user connects, he gets the data, then disconnects. All scripts are unloaded, the context is lost.
So, when you try to preserve data between sessions, you got 3 options
1.) Database
2.) Javascript Sticky Session
3.) Dedicated Session Server with tons of RAM to store it there
With 3, this server can NEVER go down
Picking 1, with every received request, you must read the database
quartz lily
yeah so basically each time someone loads the home page, it would need to make a check to the database
tired root
yes
quartz lily
isnt that a lot of reading
quartz lily
it could be 10k per second actually.
tired root
What kind of setup do you have?
quartz lily
for a span of 10-15 min
some pythonanywhere server, I can share the specs in 5 minutes
tired root
ok, then I assume there is sufficient bandwidth between the instances
in that case, 10k isn't a lot
A way to save computing and bandwidth, is to use database views
those are prestored sql calls, which save tons of time and bandwidth
ALso make use of https://pythonhosted.org/Flask-Cache/

Hi, I am creating a website using flask
I have html elements that react with javascript. I want to pass data from these dynamic elements to flask, do the necessary computing and then return the data to the html
without refreshing the website
How can I do that
quartz lily
jquery
make a request to a route which does all the necessary computations
or ajax
and then from your route, return the data
quartz lily
its just an ajax get request
or post request rather
you post data to your flask route, and in your route do whatever computations and return
rustic pebble
hm ok
quartz lily
if you don't know how to use flask routes i would suggest looking into those first
cause those are the basics
rustic pebble
will this return the value of the element?
var number = document.getElementById('clicks').value
say the value was '500'
quartz lily
Yeah
That works
depends on what element clicks is though
and thats more JS, it's much easier to use jquery
rustic pebble
function submit(){
const http = new XMLHttpRequest();
https.open("POST", "/lolcreator");
https.send;
}
This should work
but it doesnt right?
quartz lily
dude ive not seend that before
u arent doing it the way i do it, which is much easier tbh
i said ajax
ajax.get
also you arent posting any data so that would also cause an error
rustic pebble
i am doing it for test
tired root
If you need bidirectional communication, use a websocket, not ajax requests
@rustic pebble
rustic pebble
I need this:
Send request to a flask path -> flask path returns a string -> alert(string)
tired root
again, use websockets, then your frontend and your backend can talk to each other
without reloading
rustic pebble
I am not rly sure how to do that either, but I will try
tired root
Or maybe rethink if you really need it without reload
another option is a rest api with the ability to POST
rustic pebble
I really need it without a reload
tired root
why?
rustic pebble
for ux
tired root
if you explain what you do, maybe one can help you
rustic pebble
I dont want to get in the details of the project
My main goal right now is to be able to request and receive within the same session
else I could use cookies and solve my problem rly quick
umbral palm
@rustic pebble Use ajax maybe?
rigid laurel
It looks like Kiwi is currently trying to use AJAX and it isn't working. But ajax is very probably a better solution than websockets
@rustic pebble If you post your Flask route, and the whole AJAX request that you're trying to make, it'll probably be easier to help (assuming you haven't solved it). And the fetch() API is probably the best way of making AJAX requests
If you're still looking for help when you see that message, you can feel free to @ me - I might not be able to help immediately though

anyone knows how can i send a file to my flask server with requests?
rigid laurel
requests.post(url, files={'my_file' : open('path_to_file', 'rb'))
Then you need to have a post url on the flask backend
and access the file something like this my_file = request.files["file"]
full panther
oh thanks :)
i managed to send the file but when i recieve the file it doesnt recieve it in binary
full panther
rb
im not sure how to use it, what i did was
data = request.files['file']
with open(data, 'rb') as outfile:
print (output_path)
oh wait nvm im dumb
yep fixed it
all i had to do is data.read()
thanks for the help anyways
rustic pebble
@rigid laurel Hi, thanks for helping me. I have 6 buttons arrayed in 2 rows of 3. The bottom 3 control the name of the top 3 by clicking them
I want to get the names of the top buttoms as they are the desired user settings
rigid laurel
So this is a JS problem then right?
oh no
I get it
you want to post the value of the buttons over to your flask
then process them there
yes?
rustic pebble
yup
I actually want to do this but I am not sure if that is possible security wise:
User adds the settings he wants => User clicks submit => submit posts the settings to a flask route => response is calculated by the server => response is displayed real time without refresh
rigid laurel
None of that is very difficult to do with a little JS
But explaining it isn't necessarily easy
hm
rigid laurel
yeah, its the kinda thing thats easy once you know it, but very alien if you don't know it
rustic pebble
not really. I know c#
so it is not very strange to me
it just misses the linq part which i am grateful for
rigid laurel
a high level overview is that you want to:
- use the fetch API to make the post request to flask with the new settings
- In flask respond to that with a json
- Using the fetch API, when you get a response, update the html content of what you want to change
rustic pebble
that is what I was thinking
This is kinda my js right now
function sendpost() {
var http = new XMLHttpRequest();
var url = "/lolaccrequest";
var params = 'accnumber=' +clicks+'&server='+servers[i - 1];
http.open("POST", url, true);
http.onreadystatechange = function() {
if(http.readyState == 4 && http.status == 200) {
alert(http.responseText);
}
}
http.send(params);}
this sends a request to my server
rigid laurel
You don't want to be using xmlhttprequest
rigid laurel
use the fetch api or use jquery
rustic pebble
So I have been told,
rigid laurel
I'd definitely reccomend the fetch API.
But with what you have, what is the problem
updating the content on the page?
rigid laurel
what are you returning with flask? A json or html?
rustic pebble
I am not returning anything, when I reload I pass this: return render_template("/logged/user.html", data1=data1, data2=data2....)
And to display data I am using {{ data1 }}
and so forth
rigid laurel
From the client side, you need to essentially manually update only the values that you want to update
rustic pebble
For example these left are the starters of a users first and last name
along with the username
rigid laurel
so you'd want to return a json instead of the template
return dict(data1=data1, data2=data2...)
rustic pebble
This is what I am doing
<a href="javascript:void(0)" class="simple-text logo-mini">
{{ starters }}
</a>
<a href="javascript:void(0)" class="simple-text logo-mini">
|
</a>
<a href="javascript:void(0)" class="simple-text logo-normal">
{{ username }}
</a>
hmm
rigid laurel
then on the js side you select the elements you want to update
and change their values
rustic pebble
Yup that is what I want to do
But I am not sure how to read responses on js
On python you just use data = json.loads(response.text)
and u got a dict
rigid laurel
alert(http.responseText); --> let my_response = JSON.parse(http.responseText)
and then you have a JS object
rustic pebble
what does let do?
rustic pebble
oh wait
yy
ik
let me try this
I will delete the function
and redo it
function sendpost() {
$.post('/lolcreator'),
{
accnumber: clicks,
server: servers[i]
}
}
This should do the job
right?
rigid laurel
yeah, that looks right
ish
its been a while since I've used jquery
I've mostly used the fetch api recently
rustic pebble
I have never used fetch api beforehand
rigid laurel
its very promisey, but its pretty good
rustic pebble
Let me try and build with fetch api
const data = {accnumber: clicks, server:servers[i]};
function submitdata(){
fetch('lolcreator',{
method: 'POST'
headers: { 'Content-Type': 'application/json',},
body: JSON.stringify(data),})
.then((response) => response.json())
.then((data) =>{
console.log('Success');})
According to their docs
This should work
rustic pebble
let me try it
havent used it, I was waiting for ur response
I am getting this
Although I am using it
rigid laurel
async function postData(url = '', data = {}) {
// Default options are marked with *
const response = await fetch(url, {
method: 'POST', // *GET, POST, PUT, DELETE, etc.
mode: 'cors', // no-cors, *cors, same-origin
cache: 'no-cache', // *default, no-cache, reload, force-cache, only-if-cached
credentials: 'same-origin', // include, *same-origin, omit
headers: {
'Content-Type': 'application/json'
// 'Content-Type': 'application/x-www-form-urlencoded',
},
redirect: 'follow', // manual, *follow, error
referrerPolicy: 'no-referrer', // no-referrer, *client
body: JSON.stringify(data) // body data type must match "Content-Type" header
});
return await response.json(); // parses JSON response into native JavaScript objects
}
postData('https://example.com/answer', { answer: 42 })
.then((data) => {
console.log(data); // JSON data parsed by `response.json()` call
});
Try this version exactly instead - that error looks like its to do with the order in which you're doing things
rustic pebble
That being async wont mess with the rest of the js I have on the website right?
rustic pebble
oki
async function postData(url = '/lolcreator', data = {accnumber: clicks, server:servers[i]}) {
const response = await fetch(url, {
method: 'POST', // *GET, POST, PUT, DELETE, etc.
mode: 'cors', // no-cors, *cors, same-origin
cache: 'no-cache', // *default, no-cache, reload, force-cache, only-if-cached
credentials: 'same-origin', // include, *same-origin, omit
headers: {
'Content-Type': 'application/json'
// 'Content-Type': 'application/x-www-form-urlencoded',
},
redirect: 'follow', // manual, *follow, error
referrerPolicy: 'no-referrer', // no-referrer, *client
body: JSON.stringify(data) // body data type must match "Content-Type" header
});
return await response.json(); // parses JSON response into native JavaScript objects
}
What does that do
postData('https://example.com/answer', { answer: 42 })
.then((data) => {
console.log(data); // JSON data parsed by `response.json()` call
});
oh wait
rigid laurel
postData('https://example.com/answer', { answer: 42 }) // This is sending the data
.then((data) => { // This is the function that parses the response from the server
console.log(data); // JSON data parsed by `response.json()` call
});
try making your request from the crome/ff console
just paste your version of js postData('https://example.com/answer', { answer: 42 }) // This is sending the data .then((data) => { // This is the function that parses the response from the server console.log(data); // JSON data parsed by `response.json()` call });
that into the console
and see if that works
rustic pebble
Ok I fixed the request
it makes it
Method not allowed is okay, I havent configured it
rigid laurel
Yeah, thats a problem on the flask side of things
rigid laurel
thats because you aren't returning a json from the flask
I'm pretty sure
its just getting the default flask error
rustic pebble
omg, I have to scrape the temp fix I made last night, it would set a jwt cookie, and decode it on the html render
omfg
rigid laurel
which is a html 403 or whatever
umbral palm
its not valid json
rustic pebble
dict
rigid laurel
no, that will think its a set
rustic pebble
dict('Success':'True')
rigid laurel
that will work yeah
rigid laurel
{'succes':True} or dict(success=True)
rigid laurel
needs to be an equals if you use the dict() method or a :; if you do it with the literal
rigid laurel
that should work yeah
rustic pebble
If I wanted to print the response onto console
I would do console.log(response.json());
rigid laurel
postData('https://example.com/answer', { answer: 42 }) // This is sending the data
.then((data) => {
// Here data is just a JS object which you can print
console.log(data);
});
or depending on which version of the code you went with
your way should work as well yeah
rustic pebble
I am using this
async function postData(url, data) {
const response = await fetch(url, {
method: 'POST',
mode: 'cors',
cache: 'no-cache',
credentials: 'same-origin',
headers: {
'Content-Type': 'application/json'
},
redirect: 'follow',
referrerPolicy: 'no-referrer',
body: JSON.stringify(data)
});
return await response.json();
then when you call the function, you need to do postData(url, what_youre_sending_to_flask).then((data) => { console.log(data)})
rigid laurel
There you go, now you just need to replace that with some JS to update the content
rustic pebble
That is one long button
<button class="btn btn-primary btn-block" onclick="postData(url='lolaccrequest', data={accountnumber: clicks, server: servers[i]}).then((data) => { console.log(data)})">Submit</button>
Do I have to make the replace functions async as well?
rigid laurel
well, you'd just be calling it inside the then() so you should be fine to call non async stuff there I think
rustic pebble
Soo, I will have to do .then((data) => function1(), function2(), etc)
to call the functions
rustic pebble
but data is in dict, if I wanted to display only username I would do:
.then((data) => function1(data['username'])
?
rigid laurel
you could do that, but its just a js object, so you'd probably want to do data.username
rustic pebble
ooh right
damn js is fine as fuck]
If I wanted to set the data as global variables
oh nvm mb
@rigid laurel sorry for pinging. Say flask server responds with 10 usernames, I have a table which I want to update from that. I know that I can use
var row = document.createElement('tr');
But if I want to update the column values so that they match the usernames receive
received
rigid laurel
You already have the table, and you just want co change all values in a column?
rustic pebble
I want to add values depending on reponse count
so if 5 was received it would create 5 rows
rigid laurel
ah, gotcha
rustic pebble
if 10 was received it would create 10 rows
I think I got it tho let me try to write it:
var table = document.getElementById('responsetable');
for (var i = 1; i <= data['usercount']; i++{
var tr = document.createElement('tr');
var td1 = document.createElement('td');
var td2 = document.createElement('td');
var td3 = document.createElement('td');
var text1 = document.createTextNode(data['data1']);
var text2 = document.createTextNode(data['data2']);
var text3 = document.createTextNode(data['data3']);
td1.appendChild(text1);
td2.appendChild(text2);
td3.appendChild(text3);
tr.appendChild(td1);
tr.appendChild(td2);
tr.appendChild(td3);
table.appendChild(tr);
}
maybe I should do this as well:
document.body.appendChild(table)

In regard to the Django polls app:
I tried adding dunder methods like __lt__ and __eq__ to my models so that I could sort my objects by a numerical property. It works fine... until I open up my admin site and attempt to save a new object there.
https://www.ppaste.org/H1u14MQ9u
I have verified that commenting these two methods fixes it and the admin site resumes working.
You will recognize this example as the polls application from the official tutorial. I have merely added these methods because I thought it was a good idea. It is otherwise exactly the same app from tutorial 1 to 7.
https://docs.djangoproject.com/en/3.0/intro/tutorial01/
I'm curious to know what is under the hood that causes it to break the admin site functionality.
Here is the full traceback for the error, caused by attempting to save a Question object from the admin site:
https://www.ppaste.org/EhhmjVBrv
It's possible that it has to do with the id property, which isnt defined in the model but which is added by some Django magic at some unknown point. I will experiment with that
proper hinge
Because your implementation of eq is wrong
It's saying the attribute other of an object self (i.e. the current model instance) doesn't exist. And it doesn't
Because other isn't an attribute, it's an argument passed to the __eq__ function
So it should be self.id == other
However, you should compare against the id, so self.id == other.id
And then, you end up with a simplified version of what Django already does by default for equality comparison, so this is redundant.
By default Django compares the values of the primary keys of models to determine equality.
native tide
@proper hinge thank you for this response, I'm going to see if I can improve it. There are probably a lot of things that Django does that Im just not educated on yet.
Wow I feel stupid about the implementation of __eq__ thing
That was just an error I should have seen
So, the reason I added this at all is because I wanted to use sorted() on my objects and thought it was a good time to play with adding dunder methods and experiment.
How would you sort objects then if not by this way I tried to do?
I still get AttributeError: 'NoneType' object has no attribute 'id' but I know why that is. Its probably because it doesnt have the id yet like I was saying before. But, it does seem to be sorting my questions without sorted() and without the dunder methods.
the thing is... at one point is wasnt. Thats why I did this. I cant easily replicate what it was that caused that because it wasnt recent. So theres no proof that Im not imagining it :P
Either way thanks

Hi
I need urgent help
I want to calulate time between two different api calls for a user
How can I do that
rustic pebble
using epochs
@app.route('/getdate', methods=['POST'])
def add_date():
req = request.json
#print(req)
client_time = int(req)
timenow = int(time.now().timestamp())
res = make_response("")
if timenow - client_time >= 84600:
res.set_cookie('disabled', disabledjwt('false'))
else:
res.set_cookie('disabled', disabledjwt('true'))
res.headers['location'] = url_for('lolcreator')
return res, 302
this checks whether one day exactly has passed
1 epoch is 1 second
rotund crescent
Okay thanks
rustic pebble

rotund crescent
Hey @rustic pebble can you explain how this works
I have two APIs
One where uses selects a particular form to fill
And then he hits submit
So I want to record time between these two API calls
rustic pebble
On a website right?
rotund crescent
Yeah
rustic pebble
Well you need to send a POST request with the data you want, for your case datetime, using javascript
Id suggest using fetchapi
rotund crescent
Well
I have all these APIs already working
But the thing is
I want to know how long user takes to fill the form
So say I start a timer
When he hits the form url
Now I have to stop it
When the same user hits submit
I have a postgress DB
I will update the time difference in the data base
rustic pebble
I would do this with the following way:
1) When page is loaded start js timer
2) when button submit is pressed stop timer
3) pass the timer value as a parameter on your apicall
rotund crescent
You mean
I should do this from front end
And then send it to backend to update the database
But I can't do that
It has to be handled through backend
rustic pebble
Why not?
You would have to send a seperate request to start a server-sided timer then
and stop it when the apicall from the submit gets returned
native tide
@rotund crescent if u are in flask flask-moment could suit you , im bit late didnt read whole disc. tho
rotund crescent
Flask moment
Okay
Will try that
@rustic pebble I can't because I don't have access to frontend
Also
rustic pebble
How are you building the website then haha
rotund crescent
It's REST API
rustic pebble
Hmm
native tide
You have a function fromNow() in flask moment i guess u could use it to calculate times or something hm
rustic pebble
I guess you could either that ^^
If your code is async you could add a timer when the page gets loaded
rotund crescent
Okay
And I have end the same timer
For same user
When he clicks submit
But how ?
rotund crescent
@native tide Lemme check da
native tide
Is using relative paths in flask a norm or just personal pref ?
rustic pebble
I am not sure exactly how to do this but you would need to create an async function say :
async def timer():
time = 0
while True:
await asyncio.sleep(1)
time += time
return time
--WHEN USER OPENS FORM PAGE--
@app.route('/form')
def things():
task = create_task(timer())
#your stuff here
---WHEN USER CLICKS SUBMIT---
#ur functions
task.cancel()
Or you could set a cookie that contains the onload epochs
and then grab that cookie again on user submit
rotund crescent
The cookie thing works
rustic pebble
And compare epochs
rustic pebble
Just make sure you encrypt the cookie, I encrypt the cookies with JWT
Because if you want to use this data as case for something else users might try to change the cookie values
jagged lark
And it isn't actually encrypted, it is signed
rustic pebble
Yea mb
This returns a signed key for example
def loginhandler(LogUser):
headers = {'alg': 'RS256'}
key = read_file('privateKey.pem')
objectuser = session.query(User).filter_by(username=LogUser.username).first()
print(objectuser)
starters = objectuser.firstname[:1] + objectuser.lastname[:1]
print(starters)
payload = {'username': str(LogUser.username), 'firstname':LogUser.firstname, 'lastname':LogUser.lastname,'starters':starters, 'aboutme': objectuser.about , 'iat': time.now()}
print(check_password_hash(objectuser.password, LogUser.password))
try:
if nobjectuser.username == LogUser.username and not(check_password_hash(objectuser.password, LogUser.password)):
print('Wrong credentials')
return None
else:
print('User {} has been found'.format(objectuser.username))
token = jwt.encode(headers, payload, key).decode('utf-8')
print(token)
return token
except:
print("Wrong credentials")
return None
You can see the content of the cookie by decoding with base64 the part before the dot
rotund crescent
Cool thanks
rustic pebble
Does anybody know why this updates all the rows instead of the one that is inside the where?
update = users.update().where(userobject.username == User.username).values(premium="WORKS")
Is it not SQL Alchemy ?
rotund crescent
Wait
rustic pebble
I have this kind of setup rn
userobject = session.query(users).filter_by(username=str(User.username)).first()
print(userobject)
print(User.username == userobject.username)
updated = users.update().where(userobject.username == User.username).values(premium="YESYESYES")
Ah just reverse the check
rotund crescent
Okay
rustic pebble
userobject = session.query(users).filter_by(username=str(User.username)).first()
print(userobject)
print(User.username == userobject.username)
updated = users.update().where(User.username == userobject.username).values(premium="YESYESYES")
I am sorry what I said was illogical
patent cobalt
But it shouldnt matter since:
print(a==b) print(b==a)
@rustic pebble Typically, yes, but not strictly speaking necessarily so in Python
rustic pebble
I got it
rotund crescent
rows_changed = User.query.filter_by(role='admin').update(dict(permission='add_user')) db.session.commit()
bleak bobcat
Translate that to raw SQL, you're doing UPDATE whatever VALUES whatever WHERE true;
rustic pebble
hmm
bleak bobcat
Or maybe I got it wrong I've never played with SQLAlchemy, but this seems to be the case
rotund crescent
@rustic pebble use the code I sent
rotund crescent
Btw I asked you to print str(User.username)
@bleak bobcat is right you should close the session after each update and update only for single session
bleak bobcat
Just to be sure, do a print(str(updated)) you'll get the actual SQL query
rustic pebble
sec
@rotund crescent what u sent me doesnt work
UPDATE users SET premium=%s WHERE true
thats the response
god damn
bleak bobcat
:p
rustic pebble
Found it
updated = users.update().where(users.c.username == User.username).values(premium="wofefeafearks")

Can someone explain to me how decorators in flask work in our benefit for auth?
I am not rly familiar with decorators at all tbh

Decorators are just a fancy way of passing a function as a parameter
And in flask they usually permit access if you are let's say not an admin or not authenticated

My question can be a little strange. Its about web-development, but not back-end such as django, flask, etc, but about front-end. I red an article (https://www.quora.com/Is-it-possible-to-use-Python-for-web-development-without-involving-JavaScript) that tells about how we can use python is client-side web development. Basically, considering that browser cant compile python, the article tells that we can create py script, then we it will be converted in js. Now i would ask you, if anyone has ever used some of these tecnology, how are them...?
if its worth, i have just an idea to create some built-in library
jagged lark
That's one of the worst screenshot I saw in a while :D
toxic marten
Sorry these are from my phone. Wait
vagrant adder
There are a few libraries that let python run in browser they are super duper finiky and hard to work with
Such as pyodide and pyjs
I would wait few years so wasm gains some traction
jagged lark
Tbh, that sort of tech really scares me
toxic marten
Now it is from desktop
vagrant adder
Yes, docs are daunting akarys
jagged lark
Because you don't actually run the code, you compile it to another language
You just shoot you in the foot
vagrant adder
Pyodide uses some kind of magic to somehow run python in browser iirc
Actually no, it's transpiled
jagged lark
Ah, it isn't the 27Mo interpreter?
vagrant adder
My bad
jagged lark
Ah okay
vagrant adder
I'm waiting for that wasm to catch up
toxic marten
So no one is good...
vagrant adder
I know it will be few years but when we get it to run properly it will be something else
toxic marten
And brython?
vagrant adder
@toxic marten i know they are bad, noone has made proper implementation because quite frankly it's almost impossible

@vagrant adder Why did you say that it is hard work with (about python in client side programming)? I had never used it, so i dont know why😅 😄
I just tried to watch some video on yt, it seems not very difficult at basic programming, also the dom manipulation seems quite easy. I would just only to understand
rustic pebble
Is there a way I can add spacing to headers:
for example:
<h2>Hello World</h2>
this ^^ returns the same as
<h2>Hello World</h2>
Two headers inline do you mean?
rustic pebble
No
The things I typed above both give
Hello World
instead of
Hello World and Hello World
I found it
this gives u 2 spaces
so
toxic marten
im thiking to create two headers, one with text-align: left, and the other one with text-align: right. But u want to use just only one header
Or you can create something like that
rustic pebble
yup
toxic marten
<h1>Hello <span>world</span></h1>
h1 is full width
and span has margin right set to 0
try it
toxic marten
What have u used?
If u want to use bootstrap, u can do something like that with flex
<div class="d-flex justify-content-between">
<h1>Hello</h1>
<h1>world</h1>
</div>

I did my titles like this <title>Blog | {% block title %}{% endblock %}</title> in my base.html template
I should have just done Blog | {{ title }} and pass in context through the view.
Because its ultimately similar to type it as a block in every template, but its more typing at the end of the day
Which would you prefer?
I kind of dont want to redo it now that its done but I think its better to pass a title as context variable
gilded monolith
Not sure i understand what you meant, but isn't title in a separate file like you did is better ?
So if you ever need to change, you do it once, instead of changing every view?
vagrant adder
^^
native tide
Well, in each view there is context title and main title. Both work the same...
But in one, you specify the page title on a template's title block. The other way, you pass a title variable to the view. It's the same thing but different.
It's what causes it to say "about" on the about page.
tired root
Tbh, I am not using the child - parent system in jinja
I am going the old way with includes
therefore, I'd use a template variable
What you are asking is very opinion based IMHO 😄
native tide
ah, I use includes too on my base but I also have children. Either way you organize it s a lot easier than the way I did it before this which is page by page
For sure.
You're right
tired root
If it does not cause any issues,then do what feels right for you

yeah both are the same thing. It just depends on which file you'd rather have the info on.

Hi, what will be load faster on the same servers.. wordpress website/Flask/Django?
the website I want to do, can be build in all of the options.. but I want to make the fastest website as I can
I have build alot of websites in wordpress always had a bad of loading results..
and Now I just started to get into Flask and Django and feels ready to build one in these ways
bleak bobcat
Out of the box without any optimization/cache setup etc... Flask would probably be the fastest
stark yarrow
Does anyone knows how do I get the user object using the token with knox + DRF? I'm trying to authenticate a endpoint with js window.open using cookies
vagrant adder
Flask is the fastest out of those you pointed out just because it doesn't have almost no overhead @pliant falcon
tired root
However, most Python sites cost more than a PHP host, that is something to consider
My web costs me 3€/month for hosting and 7€/year for the domain, serving a blog with static html
Python hosting can also get expensive if someone is causing server stress via your script since many charge per cpu cycles
if you want a pythonic web but without running python on the web host, take a look at static site generators such as lektor or jekyll (although Ruby)
static sites have many security advantages
@pliant falcon
pliant falcon
Thanks for the answers, actually if I create an contact form in flask is it means the website isn’t static?
tired root
No, because there is dynamic code on the webserver. Static means there are only html files
vagrant adder
Yes
tired root
It has advantages and some disadvantages
I am using jekyll and one disadvantage was, that search was unavailable
I've solved this with a rest-like endpoint that can search and added the functionality via javascript
The PHP script for that was like 20 lines: https://rest.tuxstash.de/search.php?search-pattern=icinga
Doing Flaks on your own web is no simple task and you need to stay atop on things, but I don't want to discourage you, just giving options you may not be aware of
pliant falcon
ahh so actually if I dont use dynamic code why should I use python in any case.. HTML and css does everything else
am I wrong
tired root
You can use python to generate the html
Jekyll takes markdown and turns it into blog posts
pliant falcon
ahh
tired root
pliant falcon
cool
tired root
For example do you know github pages?
That uses jekyll
I've built that on my own on my RasPi
pliant falcon
so my current project is to build my an agency one page.. but with contact form
wow this website that you sent me so fast
For example do you know github pages?
@tired root Yes
tired root
which one?
pliant falcon
both
tired root
That is the power of pure html. NO delay for script execution
pliant falcon
so this Lektor and Jekyll are a differents ways to build websites with python?
tired root
Jekyll is Ruby
But yes, it is a different way to build your web. It generates static data.
However, for a one page with a contact form, I'd suggest doing it in pure html and using php for the contact form
It should be a simple script
It is the fastest and easiest way and I feel shooting with Flask onto a contact form is a bit overkil
considering maintenance and upkeep cost
pliant falcon
I actually really good with HTML and bootstrap.. the only thing I need is to build an contact form
pliant falcon
and it's just for using cheaper servers? or it's diff in performance aswell?
tired root
Considering a one page is one big file of html, performance isn't really a consideration
keep it small, minify it
regarding the php script, that executes in less than a second
I'd be more worried about bootstrap size increasing load times tbh
look for something smaller to create the page
ALso don't forget the htaccess caching instructions
those save a lot of loading time
Example from my homepage: ```apache
<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 30 minutes"
ExpiresByType text/html "access plus 1 hour"
ExpiresByType text/plain "access plus 1 hour"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"
</IfModule>```
And yes, php hosts are very cheap
pliant falcon
what is this?
tired root
Apache instructions for caching
pliant falcon
wow you giving me gold info that I didn't know
in wordpres for every thing I installed a plugin XD
tired root
Yeah.
And yes, most php hosts are cheaper than Python hosts, as I said.
For example python anywhere charges per cpu cycles
A webpackage with php shouldn't cost more than 3-4 bucks/month
including traffic
pliant falcon
Yes.. it's alot cheaper
so you say if I wanted to create alot of pages it was better to use flask or maybe flask and then one of the generaters.. but for this purpose it better to build pure html with php just for the form
the thing is that I will use bootstrap anyway
tired root
If you have a large site that requires a lot of optimization and you expect a lot of in-/output, Flask is definitely the better way. For a simple one-page with a contact form, I'd say it is overkill and increases maintenance needs needlessly.
Also building time
You can do that php script with the SO post I've linked and the rest in 1-2 days
A Flask site requires definitely more effort
pliant falcon
bootstrap makes it easy for me to handke responsivity and designing beuatiful ui
pliant falcon
thanks man
tired root
no problemo

@tired root what do you mean by CPU cycles?

Which is the default margin for dl dt dd element in bootstrap?
rustic pebble
Is there a way I can set a local css
I am trying to create a layer but the css of the layer is overlapping with the one of the main body
rustic pebble
it calls the function
What are you trying to achieve?
You could that client-sided with js
But basically
I guess you need a way to receive the request
You want live updates without any reload
?
Can you show me the render_template function you have?
Where do you want to display
The rate
But that isnt displaying it
it is an attribute
But I will lay it down for you here:
Basically when the template gets rendered you can pass in global variables.
Say you have this backend setup:
@app.route('/')
def home():
rates = get_currency_exchange_rates()
return render_template('home.html', rates=rates)
<a href="#" class="dropdown-item" role="presentation" exchange-rate="{{currency.EUR}}" value="EUR">
<span id="currency-symbol" style="padding-right: 4px;">{{rate}}€</span><span id="currency-name">Euro</span>
</a>
On page load
it will render the current rates value to the span
Unfortunately
or you can add a common id to all websites
create a rates.js file and do the following:
say id is currentrates
function loadRates(rates){
let rates = {{rates}};
domspan = document.getElementById('currentrates');
domspan.innerHTML = rates;
}
Also if you want to force a reload
hmm
I am not actually sure how you can make the server and the client refresh at the same time
You could just add a timer in server to re-render the template every 1 hour. And then set a seperate timer on the client to refresh it every one hour as well
Basically you would need this:
def reloadtimer():
while True:
home()
time.sleep(3600)
3600 is one hour in seconds
😄

I don't know flask but that kind of feature is builtin, it's a given that you' ll have multiple users at the same time.

I am setting the price for the paypal renderer on the client by making a request on my server and getting the return value
Is there a way I can make that more secured
Flask is a compiled version of CPython
It can multitask @native tide

For Django models db, how to set default rows? I want this fetch data from https://pokeapi.co , format it and insert to db while creating table.

I'm not sure I understand what you want/need, can you elaborate ?
jagged lark
@valid cypress you can set the default kward of your key
It act as a fallback if no value is provided for that key
bleak bobcat
But he's asking for rows, not columns/attributes, that's why I'm wondering what he really wants
jagged lark
I mean, a row is technically a model key
valid cypress
But this have 800+ entries
jagged lark
You have 800 entries in your model?
valid cypress
PokeAPI have 800+ entries, that I want to my db
jagged lark
Wait, you want to copy the entire PokéAPI db to your own database?
rustic pebble
I am sure you can do what you want witj an api
valid cypress
One endpoint
jagged lark
So you want to copy their database?
valid cypress
Basically, but in different format
jagged lark
You'll have some hard time copying a full database, mainly because of rate limits
But what you can do, is have a lazy database
You don't copy anything until the user request a specific data, then you ask the API and store it into your own db
But I don't see how this is related to your question
valid cypress
I'm making Pokemon bot with Django admin panel. I want get things to DB only in first setup/start.
jagged lark
I mean, you are really going to spam the API with 800 requests at startup?
It seems kind of unreasonable
valid cypress
Only first startup
jagged lark
It is still unreasonable
They have a database, why would you want to copy it entirely
You should also take a look if they have any github, maybe you can find a static file containing all the data here
bleak bobcat
It may be unreasonable but their rate limit is 100 API requests per IP address per minute so he could do it over the span of 10min
Then again if you look at their doc they have a python 3 wrapper with auto-caching : https://github.com/PokeAPI/pokebase which might be a lot more reasonable and easy to use

hey guys
that https://github.com/django-erp/django-erp is working? anybody knows anything about it?
i need to modify it
rustic pebble
@valid cypress why arent u just making on user command requests
valid cypress
Due then I'll have to do 5 request per command use.
valid cypress
First: Pokemon Species fetch
Second: Pokemon fetch
Third: Item fetch
Forth: Ability fetch
Fifth: Nature fetch
But I can combine them to one request with my API
jagged lark
You should do 5 requests per user request and use caching
Or it would takes way too much time to sync
rustic pebble
I would make a lazy db
Easiest and best
You only get what you need and it gets added to sql as well

In DTE, sometimes I see {% some_var|this %} and I'm not really sure what to call that. I've seen pluralize which seems to know if a numeric variable should have a word with an 's' or not. I've also seen crispy which refers to django-crispy-forms and sort of applies automatic CSS to a form object.
TLDR what is the word for what these are?
vagrant adder
filter
bleak bobcat
It's a filter
Some are built-in, some come from libraries (like crispy), and you can also create your own

Is there anyway I can add a seperation line between Full Name - Email and Username - Password
Sorry for overlapping ur request @native tide
toxic marten

I forgot about that
omg
toxic marten
Ok. Do you forgot about hr tag?
