Can just test using your phone

so to make a web page visible on the internet you need a domain name, with dns that points to your ip, a firewall with the right ports forwarded, and a server running on those ports
rigid turtle
http://<your-public-ip>:5000/
opal leaf
to make it visible to normal people that is
rigid turtle
Replace <your-public-ip> with whatever your public IP address is (google will tell you)
opal leaf
normies arnt gunna type in an ip address, but if you dont mind you can yourself

That's to make sure the port forwarding isn't the issue
My troubleshooting strategy tends to be start in the middle and split the search space, just like a binary search 😉

@marsh ginkgo what's the point of having computer languages? We should all just write everything in 0s and 1s. There is obviously an improvement somewhere..
@native tide Do dm me if you would like to work on something..

guys how do I go about changing a overlay position when it goes ouside the viewport. I have a hover effect in some gallery which shows info about the item. In mobile or small viewport last item hover goes off screen and its not readable
is there anyway to change its position or force it inside the main div
rustic aspen
So i have a question guys not sure if this is the write place to put it but i want to learn to use Django but i don't have an experience in python programming should i do a course on python first then one on Django or should it be fine to jump straight into Django.
unreal python
@rustic aspen Depends on your learning style I'd say. I'm going the python first, then django so I'm able to tell if an error I'd get is python syntax related or something w/ the django specific stuff.
rustic aspen
Yeah i was wondering if it would have a negative effect on me if i tried to use python for non web related stuff
unreal python
Well python isn't web specific, you can make software/games using it as well
rustic aspen
I think i might just learn at least the basics and OO python before i move onto a framework just to make sure that i have an understanding of how the language works that way i wont get screwed over when i try to branch out of web dev

Can someone explain CORS to me like I'm 5. I can't seem to wrap my head around it.
I'm trying to setup a very simple restful API with Flask and my app requesting from it keeps getting it's requests blocked by cors
import requests
from flask import Flask
from flask_restful import Api, Resource
from flask_cors import CORS
app = Flask(__name__)
api = Api(app)
CORS(app, origins="http://127.0.0.1:3000", allow_headers=[
"Content-Type", "Access-Control-Allow-Credentials"
])
class Reddit(Resource):
def get(self, subreddit):
response = requests.get(
f"https://www.reddit.com/r/{subreddit}/top.json")
status = response.status_code
if status == 200:
return response.json(), 200
return "No result", status
api.add_resource(Reddit, "/reddit/<string:subreddit>")
app.run(debug=True)```The request itself (in js) ```js
const top = http://127.0.0.1:5000/reddit/${subReddit};
const response = await fetch(top, {
method: "GET",
mode: "cors",
headers: {
Accept: "application/json"
},
});```
timid arrow
@olive wharf this one explains it really good https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS
in your case I suppose the problem is that you specify allowed origin with port 3000 while you are performing requests on port 5000.
olive wharf
I've tried both ¯_(ツ)_/¯
timid arrow
can you somehow check the response headers that you are getting in your JS?
olive wharf
Uh, I can probably log it
Nvm, It returns when doing the request
So i dont have a response to check in this case
timid arrow
? does it fail on JS side or Python side?

craggy pendant
@olive wharf I've never done it in Flask but assume it is the same.
You need to respond to the "Pre-flight" check.
The way it works is like this:
JS will check every GET request. If the GET request includes "restricted" headers, it will FIRST do an OPTIONS request to the same URI.
The Options request will NOT include the restricted headers (usually Auth headers).
So you need a handler that responds to the OPTIONS request and tell the client that it is OK to send the headers.
The JS client will then go ahead and make the normal request.
It might be necessary to add a request handler for the options request to the Flask app.
class Reddit(Resource):
def get(self, subreddit):
# esponse = requests.get(
# f"https://www.reddit.com/r/{subreddit}/top.json"
# )
# status = response.status_code
# print(response.text)
status = 200
if status == 200:
return {"data": "lol"}, 200
return "No result", status
def options(self, **kwargs):
# Set a return status
# Add the CORS headers to the response
return response

@ornate crest you need to actually show us your code if you expect us to be able to help. that traceback isn't helpful without seeing all the files it mentions. shell.html an login.html are probably culprits, my money is on login.html.

well there's going to be a title and a footer
deep cave
well this also is valid jinja.. but I've never tried to do a super and nothing else in a block that extends another empty block, since that's pointless. maybe it makes it weird up. why don't you put some stuff into these blocks just to see if it changes anything.

your code looks fine. I don't know why you're getting a mysterious error that doesn't apply to your code. dig into it with a debugging tool and figure it out. best you can do at this point.

stepping through it with pdb would allow you to print the stuff flask is parsing and figure out what it looks like. might shed some light

Currently going through Corey Schafer's flask tutorial on YouTube, give that a shot?
IMHO, it's trial and error until you stumble upon the resource that's right for you. But don't be disgruntled each time you stumble upon the wrong resource, you'll still learn something, no matter how miniscule. It'll be helpful somewhere along the way. Love the process, not the outcome.

For a scenario where I am taking a lots of files from various users for other users to download, is this -
POST file to API
Save to server and respond to user
check for vulnarability (IDK how this works)
compress (base project)
send to amazon S3
return when users requires it
a good way to go about it??
craggy pendant
No.
I did that and now I need to undo it.
You want the following type of thing
-
Client requests a "Save Location" form the API. The API gives it access to a specific location on an S3 bucket.
This is Write-Only access with no access to read on that location. -
Client dumps the file to the location.
-
Client tells the API that the file has been dumped.
-
The API then retrieves the file and processes it.
UIDs are your friend. Create a UID directory where the client can save the file.
About how to check for vulnerabilities: Do NOT re-invent the wheel. Either pay for a service or get some well supported regularly updated libraries / packages to do the job.
Once processed, add it to the Index (users listing the container can then see the resource)
The idea is to have an incoming only bucket for this workflow. The file needs to eventually end up on a CDN or something like that.
Note: The API creates a unique directory for every single request to upload a file!!! Once the file has been processed, delete the directory and file.
Also the file is not editable or deletable or overwritable by the client. Basically it is "write once"

Huh 🤔
What's that?
What am I using then?
twin thunder
Let's say, you add grid-template-columns: repeat(3, 1fr) to your grid container
And grid-template-rows: 1fr 1fr for 2 rows
1fr is 1 fraction of height
ie 1 fraction of whatever space is available..
autumn flare
Oh and remove .itemX?
twin thunder
You can do that, it would be better
autumn flare
Cheers
twin thunder
But there is another property
autumn flare
Seems padding is the spacing issue https://i.imgur.com/tsH6LSj.png
twin thunder
Which I can't remember and am. Not on the laptop..
twin thunder
It is because you haven't declared the sizes of your rows and columns
twin thunder
Ooh.. grid-auto-flow: columns to your grid container.. YeH
twin thunder
I really wouldn't recommend w3's tutorials for this.. They are really misleading
autumn flare
Haven't seen grey before, assuming it's not
*dark grey
*Atom
Yeah dark grey = invalid
twin thunder
Yeah.. Just comment it out for now and try whatever is there.
autumn flare
Sweet same as before but less lines and don't have to declare for each item
Now all I need is to figure out this spacing/distance between items/columns
twin thunder
Yeah.. Now you can just add new items and if they are inside the container, they'll automatically go to their positions
Also, do use justify-items: center; align-itsems: center
*items
autumn flare
justify-items: center;
justify-items: invalid
justify-content:
I think that's what you're after
twin thunder
Yeah.. But before you jump into it.. I'd recommend you at least go and read the grid areas and the auto-fit auto-fill
Yeah.. I guess, I don't have my lappy rn and am a bit rusty on this.

grid-template-rows: 1fr 1fr;
justify-content: center;

grid-template-columns: 400px 400px 400px;```Feels wrong though..
- I'm using
grid-template-columnstwice:
grid-template-columns: repeat(3, 1fr);
grid-template-columns: 400px 400px 400px;```
2. I have to specify each column by itself:
`grid-template-columns: 400px 400px 400px;`
Doing something wrongYeah knew it, could remove grid-template-columns: repeat(3, 1fr);
Eh still feels wrong, maybe it's not 🤔
autumn flare
Ok no, grid-template-columns: 400px 400px 400px; isn't working correctly. Weird stuff.
Using grid-template-columns: repeat(3, 1fr); but still have not figured out how to change the horizontal spacing between items/columns
twin thunder
You can replace 1fr with 400px if you want
Both lines will override each other
1fr is just measure of space
@autumn flare
Fr vh vw px em rem are all size quantifiers
Like.. They use Kg in my country to measure weigh but they use lbs or pounds in other places..
Also, the repeat(x, y) method just does what it says, it repeats a y sized row/col x times. ie you can write 400px 400px 400px or write repeat(3, 400px)

Hi all. I have a rest framewrok app where I've done a lot of work with viewsets and routers.

Going through the docs and I guess I'm not thinking of it correctly or whatnot.
teal scroll
hi
does anybody know how to call a python function when onchange
onchange=funciton()
but not js
if you are answering my question
please tag me
deep cave
@teal scroll that's not really a thing. clients don't have python installed, they have js. the closest you'll get is to use a transpiler like Transcrypt to turn your python into js.
@rare oar sorry I need more details to give you any help with that. is your rest framework a python one? making an endpoint that returns flat json should be pretty straight forward, in that case, but we'll need to know what framework you're using to help you with specifics. what have you tried so far? got any code to show us?
@kindred gate This shouldn't be that hard, but you'll need to write some JS. basically you need to use JS to make a POST request to a discord webhook URL with the correct json data.
start by making a sort of hello world - write a simple JS function that POSTs anything at all your webhook URL
then iterate on that by adding the form data to your json payload

Thanks - content works fine, just sending embeds are a bit iffy - always returning 400 errors with what I try
kindred gate
@deep cave I can't seem to get embeds working - every single time it returns 400 errors
deep cave
show us an example payload?
kindred gate
asin the code?
deep cave
as in what are you sending in your POST request
what's the payload
I'm sure the code works if the content POSTs are going through ok
kindred gate
$.ajax({
method: "post",
url: "WEBHOOK URL",
data: {embeds: [{
description: "hello",
title: "title",
}] },
success: function() {alert("SENT")},
error: function(error) {alert(error);console.log(error)}})```still errors
deep cave
can I see the error, as well?
kindred gate
"Cannot send an empty message"
deep cave
so basically it's ignoring the embeds data
kindred gate
pretty much
deep cave
okay, I'm thinking you need to set your content type to application/json
and that maybe you're currently sending it as multipart form data?
deep cave
yes, that actually confirms my theory.
it does allow stringified json if you have a form data content type
but that's cool then. I guess you got it solved.
kindred gate
is there a better way than JSON.stringify
deep cave
I don't see a problem with that if it works
kindred gate
Thanks so much for your help! :D
deep cave
you're most welcome
kindred gate
Also - while ur here
is there any way of keeping the webhook private
so that noone else can see it / post to it
deep cave
weeell. not really. the code is executed on the client, so it's going to be visible to the user.
you'd need to handle it in your backend if you want it to be private.
are you using a python framework for this website?
like flask?
kindred gate
no, pure HTML
deep cave
well, that's where something like flask would come in
with flask in the picture, you could call the webhook from the python backend, and the user would never see any of that. you wouldn't need JS at all.
deep cave
it's not super complicated, either
a simple flask app is just a single file
with only a handful of lines in it
you could probably have it up and running in a few hours.

Hey I'm trying to deploy a django app to Heroku. I'm having trouble in deploying staticfiles. When I use {% load static %} and {% static 'staticfile' %} it works in the production server. But in the dev server django throws an exception Invalid block tag on line 7: 'static'. Did you forget to register or load this tag?
This is my settings for static files:
STATIC_URL = '/staticfiles/'
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'static'),
)
i ran collectstatic
i have 'whitenoise.middleware.WhiteNoiseMiddleware' in middleware settings
if I use {% load staticfiles %} and {% staticfiles 'staticfile' %} it works on dev server but not on production server
high star
Make sure that django.contrib.staticfiles is included in your INSTALLED_APPS.
high star
your STATIC_ROOT and STATICFILES_DIRS don't match
you use the same concatenation to build the URL, but different directories

in your opinion should I use AWS instead of Heroku? I'm doing a lot of scraping with Scrapy and I dont know if Heroku will be the best choice
ugh my problem isnt with heroku. Django is not recognizing the {% load static %} tag
{% load static from staticfiles %} it doesnt load like this also although there is a static function inside staticfiles

Hey all. When I try to spin up the docker images of the main 'site' project for this discord, it works. When I run app.py for the site though I see this come through: pdrmq_1_d8841305e421 | ERROR: epmd error for host pdrmq: address (cannot connect to host/port) I have set RABBITMQ_HOST to be a different IP that pings out (this has worked in the past). Any ideas?
also fair to say that RETHINKDB_HOST was giving a similar error before I changed the IP and now this is the error coming. So I think the IP is correct.
meager anchor
epmd is the erlang port mapper daemon, nothing to do with redis
you set the rabbitmq_host variable on the site container, right?
rare oar
well in my pycharm run configuration. Is there something I need to do with the container?
rare oar
for docker-compose I am running windows. Installed the Community Edition and checked to Expose daemon on TCP. in console typed docker-compose up and built the images. grabbed the ips rethinkdb spat out and changed RETHINKDB_HOST and RABBITMQ_HOST to that ip. Updated host file
those two env vars live in my pycharm run configuration. I am just running app.py (is that correct?)
meager anchor
you set rabbitmq_host to the rethinkdb ip?
rare oar
yes I set both rabbitmq_host and rethinkdb_host to the same ip
meager anchor
but those are different hosts
rare oar
I have tried removing rabbitmq_host and I am with the same error
the epmd error only appears when I try to run the flask app.py
RETHINKDB_HOST set to the 10.0.75.2 ip which pings out.
rare oar
hmm not sure. Easy way to tell on windows? I don't see anything listed in netstat
polar wasp
netstat -a to include listening ports
rare oar
hmm didnt see any
also I just spun up docker-compose right now. I was assuming the error came from when I tried to run the site. It looks like it errors out after awhile on its own with that message above.

@deep cave Hey sorry didn't see the reply. I am using django rest framework. I'm just a bit new to it and have only used the magic ModelViewSet. If I was to do a regular viewset, would I just provide a Response that sends a dictionary instead of someserializer.data?

Hi, I'm quite new to web development, but how hard would to be to authorise with discord and make a bot web panel? All it'd be is a set of buttons that interact with a database (postgres) using preset queries per each button.
I was thinking of using django and having a fairly barebones (no css for now) webpage for it, where you'd select a server to change settings on, then it'd change columns with that server's id.
Sorry if it's a stupid question ;;
elfin trench
Is Quart a good web framework for making sort of advanced websites?
deep cave
@rare oar I'm afraid I'm not that knowledgable within DRF, but maybe @meager anchor can help you.
@nimble crow it's not super complicated. we've done something like that for our website, although that's for Flask. You can look at https://github.com/python-discord/site/blob/master/pysite/oauth.py if you want to see some of the code we're using for it.
it's definitely doable
@elfin trench in my opinion you're making it harder on yourself than it needs to be if you're using Quart for an advanced website, I'd stick with more established frameworks like Flask or Django unless optimal performance is absolutely paramount. it's hard to say without knowing more about what you mean by an advanced website.
elfin trench
I'm using this for my upcoming discord bot. It's gonna contain a API of user info/leaderboards, a dashboard, and a admin dashboard of statistics and such
uh
sry I accidently deleted
sorry lol
zinc cypress
Wrong lemon... Again
deep cave
you're putting the API directly in the bot?
because that's geeenerally a bad idea. it gets really messy.
it's generally just a better idea to keep the two apps separate and have them communicate.
elfin trench
no on the website lol
rare oar
hey @elfin trench I've done the same on my discord bot. If you run into any questions shoot me a pm. I've uhhh... learned quite a bit not knowing anything about restapi etc. Web end is a django app with Django Rest Framework. Bot uses discord rewrite
@deep cave I got it figured out. Thanks 😃 😃
elfin trench
I though of using Flask
rare oar
yeah flask is definitely a use case
especially if its only an api. I wanted to flush mine out to be a full on webpage later on and just have the bot act as a client for management in discord (its for game organizing and stat tracking)
elfin trench
well
It was going to be a dashboard
and a admin dashboard for statistics
and a API
rare oar
ok. whatever you are comfortable with. I still think Flask is an ok choice. I chose Django because I had done a tutorial or so in the past
and kind of understood it better
rare oar
easy choice then 😃
for the bot, not sure if it was the right way, but I went with a mixin that I put on my COG class that gives it access to the web api
at first I tried data classes, but man... I was getting a lot of naming and recursive import issues because my cogs weren't loosley coupled
so I went with that route instead
elfin trench
I'm thinking of using aiohttp or something
to communicate
or sockets idk
I'm just unsure of what I'm gonna do when communicating cause I haven't learned those stuff yet lol
rare oar
I use aiohttp
elfin trench
The thing is I'm not sure of how I can get information from the bot to my web app. Like how would I tell my bot to send that information lol
rare oar
what do you mean?
I think it would be like any POST call
I need to refactor this as this is a method not in my mixin now, but heres the gist of what I do:
async def api_base_method(method: str,
endpoint: str,
resource_id = "",
session=None,
**kwargs) -> aiohttp.ClientResponse:
"""Generic function that takes a method for a web api call.
Valid are GET/PUT/POST
endpoint is the full url path.
"""
url = endpoint if resource_id == "" else f"{endpoint}{resource_id}/"
log.info(f"Calling api_method: {method} on {url}. ")
for key in kwargs:
if key == 'json' or key == 'data':
log.info(f"api_method {key.upper()}: {kwargs.get(key)}")
auth_token = os.environ.get('API_AUTH_TOKEN', None)
auth_header = {'Authorization': f'Token {auth_token}'} if auth_token else None
if not session:
session = aiohttp.ClientSession(headers=auth_header)
response = await session.__getattribute__(method)(url, **kwargs)
response_status = response.status
response_text = await response.text()
await session.close()
else:
response = await session.__getattribute__(method)(url, **kwargs)
response_status = response.status
response_text = await response.text()
log.info(f"api_method {method} returns {response_status} - "
f"{response_text}")
return response_status, response_text
async def get_record(self, endpoint: str, id: int, **kwargs):
"""Returns a web api object from our database.
:param endpoint The endpoint to target. ex: `match/`
:param id The pk of the object from our web api.
:return dict A dict representation of the object.
"""
endpoint = f"{self.api_root}{endpoint}/"
status, record = await api_base_method(method='get',
endpoint=endpoint,
resource_id=id,
**kwargs)
if status == 200:
return json.loads(record)
I also have a save() method which does a post.... but its a bit long and really needs refactoring
heres a command from the bot:
@events_group.command(name='checkout', aliases=('co',))
async def events_checkout(self, ctx: Context, event: EventAPIObject) -> dict:
site_member = await self.get_record('discordplayer', ctx.author.id)
log.debug(event)
event['players_checked_in'] = utils.remove_dict_from_list(site_member, event['players_checked_in'])
await self.api_save('event', event)
await ctx.send(f"Succesfully Checked out {ctx.author.name} from Event {event['id']}")
POST methods send information right?
rare oar
yeah POST is for creating something in the database

Depends on whether you're going hardcode and do all of this yourself in html or css, or if you use a framework.

still briar
If it's just about styling, I'd use Bootstrap.
wary mantle
Hm 🤔 . But would it be quite difficult if im going hardcode?
still briar
Depends on what you're aiming at. If you're mostly interested in the structure, such as having the big text top left, then body text to the right, that needs some proper layouting.
But if you want to make it just as pretty, there's a lot you'd have to add, I suppose.

Hey!
Using Flask, I'm trying to:
- Click a "Test pump" button.
- Call a "pump_water.py" script on the server.
- Update the HTML with a "Pumping..." text.
- When finished, set that text to "Test pump"
But I can't get it to update both after and before the pump is done.
My flask code atm:
def pump():
pump = Popen(["python3","/home/pi/Circuits/Pump/ttest.py"] )
data_template = template_creator({"pump_info":"Pumping..."})
print(data_template)
#UPDATE HTML HERE
yield render_template('index.html', **data_template)
while pump.poll() == None:
print("Inside!")
time.sleep(0.5)
#UPDATE HTML HERE
return render_template('index.html', **template_creator())
return render_template('cakes.html')
Note: the yield obviously causes an error with returning a generator, it's just there to show where I want to return.
Any and all assistance appreciated!

you can also learn css and other web stuff from there

@native tide You can make a searchbar with class based views
You will need to make use of the get_queryset() method
example
where it says self.request.GET.get('term') it gets the data from the form named term
you can of course name the form anything you like
the second last line filters out any posts that are not matched with the search query and only holds posts that are relevant to the query
You'll need to add something like this to your templates
inside the form, you would make a {% url %} inside the action attribute that links to the url you specified for your class
In addition, you would set the method attribute to GET
In this line
<input class="form-control mr-sm-2" type="text" placeholder="Search posts" aria-label="Search" name="term">
The name attribute is set to term. It can be anything you like but it must match the name you put in your view's code. This is how the data from the form is collected.

Thanks a lot that will be a good start for me

my gosh. I am convinced I approached my models wrong. Every instance is a battle against the number of queries generated. I put in a simple jinja2 view and I'm generated 3000 queries on the relationships
I don't understand. In Django if I do MyObject.somerelation_set.all() it just explodes. Its such nice nice magic, but it murders performance
if anyone is available, can they help me digest it? I'm sure its just my understanding of how to query it
native tide
Thanks @grand badge that helps me a lot
native tide
But a similar question about searching in django; I can send queries using the form element, but how would I send a query using a link? For instance, if I have a word that acts as a tag and if a user clicks on it, I want it to go to the search page with the word entered as the query.

Heyo
So I'm going to make a temporary file hosting site with Flask.
It's going to have expiration options, so I'm wondering what I can do when a file expires as someone is downloading it?
floral dust
Are there any Bottle, CherryPy, Falcon, Pyramid, Responder, or Sanic devs in here?
full arch
@lilac hound that shouldn’t matter, the file will be locked while it’s being read, and then once it’s in memory and streaming to the user it will be free for deletion
lilac hound
@full arch I should say this though
I'm going to be storing the files (max 50mb) in a database, since I want to password protect and encrypt them
So when a file expires I just will remove it from the database
But I kind of figured it would be that way though in regards to it being read
full arch
Same thing, you won’t be streaming directly from the database. But you really shouldn’t use a database for file storage, it’ll destroy performance
lilac hound
Well, what's another way of doing this?
I just want the files to be secure, encrypted, and passworded.
A database seemed like the best option since I could just have two datefields, submitted and expires, to run a cron job against
paper raptor
@floral dust I've used cherrypy a lot and I've contributed to development. What do you need to know?
floral dust
@paper raptor I have been working on a security headers / cookie project and would love some feedback - https://github.com/cakinney/secure
paper raptor
I'll take a look at it. Its a lot to go through, but could save much time.
Part of why i love cherrypy is that it doesn't do much and doesn't get in the way, but the downside is having to do a lot of stuff manually that could be done much easier, like this.
floral dust
Thanks! I would really appreciate any suggestions - I know it has a lot of moving parts
Agreed! I wanted to create it for those micro-frameworks without this support built in. I am more security engineer than developer so this is my way of giving back.
full arch
@lilac hound a database isn’t inherently more secure than file storage. You would need authentication for either if you wish for secure access.
I would recommend a database to store your file meta-data (age, creator, etc) and a path/uri to the file.
lilac hound
@full arch I am just not sure about encryption/decryption with that
Have any libraries you can suggest for that?
full arch
Quick google got me that, @lilac hound
That flask plugin isn’t currently maintained by the looks of it, but the library it uses is still active https://github.com/andrewcooke/simple-crypt
For authentication/administration , I’d recommend https://github.com/flask-admin/flask-admin
If you don’t need an admin dashboard, https://github.com/mattupstate/flask-security

How much RAM would a small Flask server and a few web pages take up? (if that's measurable by RAM?)

What would be the best way to implement Flask into my website?
I don't want it to "load a new page", which I've seen iterations do. I just want it to do some python functions.
native tide
For the love of God, I can't figure out why my site sometimes loads, & sometimes why it directs me to DNS search, as if it doesn't exist
Its acting like I'm using the Flask development server (but I'm not), I'm running Flask/uwsgi/Nginx
Anyone know of any reason why this would be happening, in general?
What weird error would be causing the site to work only half the time
brittle glacier
So has anybody here really touched Flask?
prime ridge
I have!
@brittle glacier ... Little late, soz. But yeah, big fan. I'm deploying a flask app to production for my school where I work this week.
brittle glacier
@prime ridge Awesome to hear! Do you have any clue why I keep getting "Method not allowed" when I call this with jquery?
prime ridge
:O
Never seen templating used in javascript before. Usually serve them as static files. I take it that javascript isn't being served as statically despite it containing template code, right?
you might want to add a print(request.method) to your view and see what's happening when you get that message
Also, I don't think methods are case sensitive, butttt
nah that's dumb
but in some code I'd written previously I had <form method="POST" action="/admin/"> allcapz
brittle glacier
prime ridge
oh gosh
brittle glacier
When I do "method=POST" in the form, that is when I get the "Method ot allowed"
never any other time
Wanna see if you're able to do it?
prime ridge
Yeah, sure!
brittle glacier
HTML form -> jquery -> flask
It should be a JSON file in Flask

Hello.
Being unsure to which channel to post to, web development seems to be the closest one.
What I'm trying to do is to get the data from https://www.portal.reinvent.awsevents.com/connect/search.ww in text format. Looks like it was done before, but with using browser emulation: https://github.com/mda590/reinvent_schedule_extract.
I'm trying to put up a plain python script without browser emulation.
I have tried to send few requests and figured out that first POST to get the data is sent like so:
data={
'searchType': "session",
'sortBy': "abbreviationSort",
},
All subsequent requests look like this:
data={
'searchType': "session",
'more': "true",
},
Somehow server knows what data to send with this "more" request and I was unable to figure out where does it take the data from. There is no such thing as "page" or "offset" in the request. Cookies do not seem to contain any kind of "what data is loaded last" hints, neither does the local storage. Same goes for POST request urls, they are always the same.
Essentially, the question is - where and how does the server get the info, based on which it decides which piece of data to load next? Function names, requests and other hints suggest site uses http://directwebremoting.org/dwr/index.html to serve this page. I'm unsure where to dig further.
Any advice, please?
Thanks.

hello guys I am using tornado
and I want to do some super heavy processing after a user has uploaded a zip of images
this processing will take a long time so I think I should run it in a new thread
or should i just hold the http request
the heavy processing is on a gpu
paper raptor
Depends on what response you need to send to the user
paper raptor
Then i'd run it in a new thread and just send a confirmation response back to the user
proud igloo
that is how I have currently written it
paper raptor
that way your connection isn't taken out of the connection threadpool for ages
and the client won't timeout

@brittle glacier can you give more info on the stack trace? is that occurring on the client side? In the browser?
could it be a possible CORS issue ?

Gotta be honest I don't have a ton of time to spend setting this up tonight. If you want to setup your issue using repl.it so I can actually just go in and tinker with the working code I'd be game
I tried but
brittle glacier
So the goal is:
- html form
- jquery
- dict in Flask
prime ridge
you have some dependencies I couldn't find on pypy
or you didn't include all the files
prime ridge
The bottom one
prime ridge
isn't that, like, needed for one of the routes you're having issues with?
prime ridge
prime ridge
uhhh
One thing I noticed
you're not loading jquery at the end of your page
jquery should be loaded right before </body>
File "main.py", line 6, in <module>
from cron_handling import CronHandler
File "/home/runner/cron_handling.py", line 5, in <module>
from crontab import CronTab, CronSlices
ImportError: cannot import name 'CronSlices'``` dood idk what version of crontab you're usingYeah, I gotta give up on trying to reproduce your environment. Feel free to upload your project to repl.it and I'll take a whack at it if you get it running there
brittle glacier
@prime ridge tbh you can just remove the crontab stuff. I can handle all that as long as I get a dict into python
prime ridge
Noooooo. I don't wanna sift through and see what code is needed and what isn't.
I do that all day at work.. ;_;
brittle glacier
I'll make a narrowed version in a sec! 😃
prime ridge
I'll try it.
brittle glacier
Didn't mean to imply you should clean the code yourself, sorry for that!
Also, with that code only the form is usable, but that's the only thing that isn't working for me
prime ridge
ok got it
I mean
I didn't fix it
just, it's running
index.html is refreshing infinitely, why?
brittle glacier
Yeah I had the same problem last night
Removing the evenDefault from jquery should fix it
No fucking clue why
brittle glacier
Tried to make it stop refreshing but it just spammed refresh
Oh really
Lemme see
prime ridge
you mean EVENT default?
brittle glacier
Top one
prime ridge
ok so
I see the problem immediately
and I kinda hinted at it last night
It redirects to /?Minute=fdsf&Hour=dsf&Daymonth=sdfsd&Month=dsfsd&Dayweek=dsfsdf -- you can't POST to that, because that's part of your index() route
it's not going to your result view
<p>Submit<input type = "submit" value = "submit" formmethod="POST" formaction="/result"/></p>```That seems to be working fine.
lololo
@brittle glacier
although you may want to delete the second "submit" since it's a little... repetitive
altho wait is that even ajax
looks like it's actually just posting the data normal
brittle glacier
@prime ridge So that works?
prime ridge
It works like a normal form
but it's not ajax
doesn't look like you have any ajax written
to go to /result
brittle glacier
function formSubmit(){
form_data = cron_form.serialize();
var promise = $.ajax({
type: "POST",
url: "/result",
data: form_data,
timeout: 10000
});
}
oh derp
brittle glacier
Bottom of tha ajax
prime ridge
at formSubmit (?Minute=&Hour=&Daymonth=&Month=&Dayweek=:194)

Also, I might recommend looking into tornado
it uses websockets and might make your life easier... or harder
prime ridge
Nice. Use supervisord or something to make sure it can handle failure
brittle glacier
no clue what that is
brittle glacier
but getting this damn thing to work is step uno \o/
prime ridge
i believe in you
prime ridge
I'd recommend "restarting" (don't freak out, you can copy and paste old code as it becomes relevant) and just focusing on getting a simple form working.
Why do you want the form to use ajax?
brittle glacier
Wait I got a step further
cron_form.addEventListener("submit", function(event){
event.preventDefault();
cron_info.innerHTML = "mat";
formSubmit();
});
The innerHTML worked
and it does not refresh
prime ridge
:o
prime ridge
:o?
prime ridge
:ooo
brittle glacier
Fuck if I know how it works
Shortened it to
cron_form.addEventListener("submit", function(event){
event.preventDefault();
var values = $(cron_form).serializeArray();
formSubmit(values);
});
Appearently the dollar signs are important
prime ridge

I'm designing a Flask Restful API and I am having a hell of a time trying to figure out how to do validation which also has the appropriate HTTP status code.
EG: Trying to view a resource from the API that has expired should return 404,
Attempting to sign in with invalid credentials returns 400, etc.
I've gotten by with doing credential validation and 400 codes with Flask-WTForms using the Flask-WTForms-Json extension, but I am beginning to lose the battle here.
I have had to do this:
class PastePermissionValidator: # TODO: Couldn't this be a WTForm validator?
def __init__(self, paste_uuid, username, data=None):
self.paste = Paste.find_by_uuid(paste_uuid)
self.user = Account.find_by_username(username)
self.data = data
def paste_exists(self):
return self.paste is not None
def validate(self, include_edit_perms=False):
if not self.paste_exists():
return {'errors': 'Paste with specified UUID not found.'}, 404
user_owns_paste = (self.user.id == self.paste.owner_id)
paste_requires_password = self.paste.password is not None
request_password = None if self.data is None or 'password' not in self.data else self.data['password']
if include_edit_perms and not user_owns_paste and not self.paste.open_edit:
return {'errors': 'You do not own this paste and open edit is not enabled for it.'}, 401
if paste_requires_password and not user_owns_paste:
if request_password is None:
return {'errors': 'Password is required.'}, 401
elif not self.paste.password_correct(request_password):
return {'errors': 'Password is incorrect.'}, 401
return None
Does anyone know of a good restful API validator library I can use to help me with this?
I'm honestly thinking of just rolling my own soon

context.options |= ssl.OP_NO_TLSv1
context.options |= ssl.OP_NO_TLSv1_1
sock=socket()
sock.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)

does any of you know how to get that image?

/assets/images/bg/logo-image-masdar-en.png - prepend it with the protocol and website domain.
So that it looks like http://website.domain/assets/blah-blah.
But most of the time you can just right click it and save.

ahh it worked. thanks!
now when i used it as my background.. the font color black was no longer a good color.. how can i change all the fonts to white in this code:
% rebase(skinning + '_skin.tpl', title=page_title) # (See note above)
% # From here, concentrate on the content we would like to show:
<!-- Lines not starting with % are standard HTML. This HTML code is defined in views/all_items.tpl -->
<div class="table-responsive">
<table class="table table-striped">
<thead>
<tr>
% for k in displaykeys:
<th scope="col">{{k.title()}}</th>
% end # Usual python indention to structure code does not work in .tpl files - "end" is used instead to end a block
</tr>
</thead>
<tbody>
% for i, d in enumerate(displaydata): # displaydata is expected to be a list of dictionaries
% link_url = "/events/" + str(i + 1) # relative url to detailed view
<tr>
% for k in displaykeys: # Go thru the keys in the same order as for the headline row
<td>
<a href="{{link_url}}" alt="See details">{{displaydata[i][k]}}</a>
<!--numre-->
% print (i)
<!--category-->
% print (k)
</td>
% end # Usual python indention to structure code does not work in .tpl files - "end" is used instead to end a block

% end
</tbody>

any idea @candid basalt ? sentence starting with "%" has some python code in it.

Changing font colors and such is a task for CSS.
In CSS you would do it something like this:
body {
color: white;
}
hmm but i dont think im doing any css here
strange thorn
yes but you have to if you want to do color stuff
whole goblet
ahh okay. What does it take to do that in general? like do i have to downloade something, make a new file or?
candid basalt
Make a new file and add a respective tag into your html template.
Does a pretty good job on explaining the basics.
whole goblet
wait. i just got the job done. Just inserted this line style="color: white;"
like this <h1 style="color: white;" >Testing font color</h1>
it worked. So is this what is meant by "using CSS" or was this just an html solution i just found?
@candid basalt when i inserted the logo that u helped me find from before, It "pushed" my text in the middle to the right even though the logo doesnt "touch" the text... how could i make the text come back, ignoring the logo and instead just stay where it was?
candid basalt
Not really.
There are few ways to use CSS.
You can make a separate file and load it by adding a respective tag in the HTML.
That's the approach I would recommend.
On you can use CSS inline, just like you did.
Using it inline will make it harder to propagate changes to all the elements.
For example if you have multiple h1s, you will have to put style for each one of them.
While in CSS file you can apply style to all h1s at once.
And if you change it - it also changes for all of them at once.
@whole goblet I'm not really into frontends, but I think you can set position for the logo to remove it from the document text flow.
It's also CSS. Something like position: absolute.
whole goblet
ahh okay thanks 😃

what's the easiest way to deploy flask online and host it locally?
candid basalt
Like host it from your local computer to the outside world?
modern acorn
yeah
candid basalt
Well it depends on what you want of it and what usage do you expect from your website.
But gunicorn+nginx should do the trick just fine.
modern acorn
It's only going to serve like 4 people lol
and just display some items in a database
I just finished making the app but need to deploy it now
candid basalt
If that's a tempory solution you may be able to get away with just it's own development server.
Although I would not recommend having it running to the outside world for an extended periods of time.
I mean the app.run() one.
modern acorn
It's going to be run all the time at a company
candid basalt
Fast, easy, dirty, slower and may be even insecure - app.run().
In the long run - gunicorn+nginx.
Or apache, whatever you prefer.

gunicorn is unix though?
