all this stuff is new to me so I'm excited; just wanted some insight other than what I read on google.

Yea think of JavaScript of adding dynamic content to your website like animations (although css can do some too nowadays) or making a webpage that doesn’t have to “refresh” to get new data. Python fits in as the backend or server to serve your website it’s content and JavaScript will do things to that content.
devout nebula
I see, thanks for the clarification... Python is the engine in the car.. but JS is the steering wheel and the Radio.
while CSS is the appearance? lol

When I do py manage.py shell I can't type anything after
Why is this?

might need to verify python and django is installed and working.
maybe make sure you are using the python with the django installed to run it
python -m pip list```

@hollow flower , I haven't worked too much with flask_restful, but I bet you'll find the answer in this doc http://flask.pocoo.org/docs/1.0/views/
in particular, how to set up views

I have no views, yet other ones work fine.

Sure, but it's probably opinionated and requires a setup you're probably missing somewhere
Which endpoint is it thats failing?
I could only guess that what you're returning is not valid (e.g. the Auth.<functions>)

Not strictly Python-related (possibly strictly unpython related) but any advice for learning how to learn enough javascript to make better Flask/Django apps? Are there any tools that provide shortcuts either in the Python language (or jinja2/django templating), or in the PyCharm IDE?
@hollow flower Any more context? This looks familiar
what are you trying to do exactly?

Create access_tokens with flask-jwt-extended, and use username as identity.

What is data['username']
Is that just a string?

Are you passing a list anywhere it's either getting used as a dictionary key, or between processes (e.g. to a worker) or anything?Check this example out too, maybe.
https://flask-jwt-extended.readthedocs.io/en/latest/tokens_from_complex_object.html
hollow flower
data['username'] is basically a string, from json request.
prime ridge
basically a string, 🤔
I noticed before you did
username=data.get('username')).first()
Which suggests to me that data['username'] isn't a string.
@hollow flower
If it's a list, it would explain why that line of code is giving you the unhashable type error.
hollow flower
Oof, that's probably my problem.

You need to make another endpoint

?
kindred cosmos
Which would require you to make another function
@app.route('/search')

searchterm = form.getvalue('searchbox')
print(searchterm)
Whoops...
I forgot it's three back ticks
uneven jasper
What i'm trying to do is make randomly generated forms for people to take and then the data get's sent to me via email.
Should have I used the search input type?
kindred cosmos
Are you talking about your html?
uneven jasper
Yes
kindred cosmos
You're html is fine
Your code is not
You need to make another endpoint/route for where your search form will submit to
Vc?
uneven jasper
I dont know.
I'm trying to print it to make sure I can store the input in a variable.
Once I get it in a variable I can use it accordingly
kindred cosmos
I understand that
But you still have to create a new route to do that
Right now there's issues in your code that need to be fixed for that to happen
uneven jasper
Oh, so the form and searchterm should be in a route so they can loop?
kindred cosmos
What loop
uneven jasper
So they can be executed more than once?
kindred cosmos
Yeah you don't need a loop to do that
kindred cosmos
Okay now you need to make sure that your html form action attribute is set to that route
uneven jasper
Ok
Alright, I got this: builtins.TypeError

uneven jasper
Okay
So I typed in "None" the first time. Apparently it means something because even when I reset it, it prints 'none'.
kindred cosmos
Yeah so you are using some cgi library when your application is running in flask
It's fundamental how cgi and flask work
uneven jasper
?
kindred cosmos
Get rid of the line form = cgi.FieldStorage()
kindred cosmos
then change searchterm = form.getvalue('searchbox') to searchterm = request.form['searchbox']

prime ridge
If left unspecified, do users submitting requests to a Flask application have any say over what type Python interprets a parameter as?
Here's my example.
b = request.args.get('b', 0) # Note I did not specify type=int, so the server may assume str```These should both be type=int for the calculator to function
It seems that, when used normally, the type will default to str
but I'm wondering if the user (e.g. a malicious one) could somehow make the server parse it as a list, or some other type
fathom prism
@prime ridge , the rule is to never trust the user input
prime ridge
Of course that's the rule
fathom prism
They could possibly take advantage of Python's duck type and could possibly perform malicious acts that will break your application
prime ridge
Yeah, that's exactly what I'm getting at. But is it ACTUALLY possible, is the question
I wouldn't write sites that way
prime ridge
If Flask handles it then it isn't possible.
e.g. if flask always defaults to a string
fathom prism
Ok, sure. Why don't you write some tests then to confirm if thats true?
prime ridge
I don't know how
prime ridge
I know how to write unit tests
I don't know how I'd forge a GET/POST request that tricks Python into typing something other than a str
The question to begin with is whether that's possible.
fathom prism
Use postman or curl
I don't know enough of the internals, but its better to test or read the source code itself
prime ridge
I did, but I stopped when I didn't know how to specify type in a request. I'd imagine there might be a header for that.
I know you can specify content type, but idk if that's just for any field
I think that's more for, like, whether you're sending json/xml/etc
Flask has an option to get a list from a request, but you have to explicitly use that function and it'll check for duplicate parameters
e.g. item=1&item=2 == [1, 2]
fathom prism
So I'll give you a simplified example.
Lets say your application is sending JSON which can have different types and your function was expecting a string, but supposedly could also get a number
fathom prism
Flask will not deserialize it to correct the term
type*
that YOU expect, it will deserialize it whatever was sent
its up to the developer to handle the different types of JSON payloads at that point
prime ridge
Yeahhh, lemme check and see what happens if I pass a json int when the type is unspecified
fathom prism
Its why we have libraries such as https://python-jsonschema.readthedocs.io/en/stable/
prime ridge
Looks like by default flask doesn't parse arguments from json. I guess that's a behavior you have to code manually
.get_json()
okay, so if you DO that though
if request.method == 'POST':
a = request.get_json()['a']
b = request.get_json()['b']
return jsonify(result=a+b)```Sending
{
"a": "1",
"b": "2"
}
``` returns `"12"`but sending
{
"a": 1,
"b": 2
}```
returns `3`Yup.
prime ridge
Interesting. I know some really badly coded python sites where, were it possible to specify type on the inputs like this, it would be catastrophic
I've read code with really bad input validation that uses iteration to validate input that goes directly into an SQL query where, were you to give it a list, you could bypass that check entirely
prime ridge
Ha, I wish. It is a company I code for, but they're too stubborn to replace this awful legacy code.
Some day...

this might seem like a crazy request idk
but im trying to run flask and discord in the same application
this is what i have so far
from flask import Flask, jsonify, request

#Post discord embed
return jsonify(data), 201
if __name__ == '__main__':

i tried to add on_ready() and bot.run() but the site refused to load
i want to make it so that when it receives a PUT request, it uses that data in the discord embed
still gazelle
@hollow flower the webpage wont load
hollow flower
How are you calling it?
still gazelle
@hollow flower one sec
@hollow flower ```py
from flask import Flask, jsonify, request

from discord.ext import commands
from discord.ext.commands import Bot
import asyncio
app = Flask(name)
#Discord Bot Loads
Bot = discord.Client()
bot = commands.Bot(command_prefix='--')
bot.remove_command('help')
@bot.event
async def on_ready():
await bot.say("Ready")
#Waits for PUT Request
@app.route('/questionData', methods=["PUT"])
def newQuestion():
data = request.get_json()
return jsonify(data["answers"]), 201
if name == 'main':
app.run(debug=True)
bot.run("")
Last time I checked, you probably can't mix async code with non-async.
hollow flower
Does the bot log-onto Discord though?
still gazelle
hmmm
#Waits for PUT Request
@app.route('/questionData', methods=["PUT"])
def newQuestion():
data = request.get_json()
#Discord Embed goes here.
return jsonify(data["answers"]), 201
So what's your goal exactly?
still gazelle
to send a message in discord using the data included in the PUT
and for it to send the message right after the PUT
hollow flower
Then your code is wrong. You can return the 201, but you don't need to the data itserlf.
Code the discord embed part.
hollow flower
Just try and see.
hollow flower
And is that bot.run() inside the if __name__ == '__main__': identet correctly?
still gazelle
No.
hollow flower
Ident it.
hollow flower
And try it.
hollow flower
The bot is connected though?
still gazelle
im going to run it through putty to see if it connects
still gazelle
does it need to do anything on ready?
hollow flower
No, but I have this.
@bot.event
async def on_ready():
bot.uptime = datetime.datetime.utcnow()
# Create database connection
#bot.pool = await asyncpg.create_pool(config.postgresql, min_size=3, max_size=5)
await bot.change_presence(status=discord.Status.online, activity=game2)
print(f'\n\nLogged in as: {bot.user.name} - {bot.user.id}\nVersion: {discord.__version__}\n')
this is the error im getting on putty

You're doing it incorrectly. That's not a the proper way to send a message.

what do you mean?

Are you on rewrite branch?
still gazelle
no
hollow flower
FUck
still gazelle
what
fluid horizon
where is this send_message from?

Why use discord.py v1.0 (rewrite)?
Reference the tags in the brackets for details on specific points.
• Improved documentation
• Context always passed for bot commands
• New ctx shortcuts
• Robust websocket reconnect logic
• Model-based OOP
• Ability for sub-commands to not invoke parent
• Async checks and events
• Case insensitive command name support
• NSFW channel check support
• Channel category support
• Animated emoji support
• Audit log support
• Webhook support
• Improved activity support
• Memory and performance improvements
• New raw events and functions
• Bot and Cog Template creator
Why not?
Rewrite is stable, but still in active development. It is discouraged to use if:
• You won't keep your library up to date
• You won't keep your code up to date with any breaking changes
• You won't subscribe to news of breaking changes with ?rewrite
• You don't want to rewrite your existing code to be compatible

luna, im trying to get discord.py and flask to run on the same app
hollow flower
Example of correct way of sending a message.
await client.send_message(message.channel, 'Hello')
may i ask why?
still gazelle
so that on PUT it uses the data to send a message in discord
fluid horizon
@hollow flower you can use send_message on discord.Object, not really advised, but it's valid
polar wasp
wait, i thought there was some reason you couldn't
fluid horizon
it's in async faq, it grabs the id from it iirc
still gazelle
its been working for me
fluid horizon
you can't do this in rewrite though
still gazelle
is what am trying to do possible?
fluid horizon
it's also not the greatest idea to run both a flask server and a bot in the same process
still gazelle
how would I send a message on PUT then
fluid horizon
out of curiosity, why a webserver? couldn't you integrate this directly to the bot?
still gazelle
others will be performing the PUT
again, the data will be put into a message on discord
fluid horizon
ah...
still gazelle
wish it was as easy as creating a json lol
so is what am trying to do not possible?
ok
so im testing this on putty
and as soon as i do control +c, it prints "Ready"
so I assume only one can be run at once
coral sorrel
Heyo
still gazelle
hi
coral sorrel
Your issue sounds like you're attempting to run the blocking start calls for both the bot and the flask site at the same time
still gazelle
basically, yes
coral sorrel
It's best if you separate the site and bot into two different processes instead
still gazelle
how would i make a command activate after PUT
coral sorrel
Otherwise if you must have it, you need to use non blocking start calls to run them and handle the loop running yourself
With flask though you probs should be avoiding the development server environment which is likely what you're using
If you only want an API, why not take advantage of aiohttp
It's already part of the bots dependency list with dpy
coral sorrel
Since you have things already it'll make things a little simpler but you'll still need to read up on how to create the API endpoints with the lib.
And sure you could call discord send message API endpoint but that's a bad idea
still gazelle
ok
coral sorrel
If you want to just emit a message and not interact you should use webhooks
still gazelle
hmm
that might be a good idea
i think im going to try to use webhooks
because that would make sense
coral sorrel
You don't have to worry as much about ratelimits or the bot API complexity, plus you can still send all the normal stuff: content, embeds, attachments.
Plus you don't have to stress at all about bot accounts or permissions.
It's worth using if it's only meant to be message emitting
still gazelle
@coral sorrel webhook worked btw
attempted to call the discord create message API manually, but didnt work

I have image directory I'm working with on a live server by atom the images work when I click on the index.thml but don't work when on the live server
the path is standard path to the sub directory where the images are
anyone know of why the live server would not display images ?
elder nebula
It should
@fair pumice Did you tried to get the images with css url()?
Because that doesnt work for live server, for obvious reasons. Because then the live server owner could explore your computer.
The images must be on the same folder as the index.html
Otherwise, it doesnt work

Hey guys. Anyone here know django?
I need to create a painel in my website with django + rest
i see that django admin default painel have the options to create users and groups
and can give acess to each table for each user/group
but i friend my told me that's unsafe and can cause vulnerability
but i see that's a very easy way to do this.
anyone can help me to understand?
elder nebula
@native tide It can be unsafe, if you don't know what are you doing. Django is pretty much safe, because the code is hidden. If that project isnt going to public, then you dont need to worry about safety so much. I suggest you to get started with tutorials on youtube. I got started with Corey Schafer's Django blog tutorial, you get the basic idea, how to create login and register system, views, How to delpoy and other stuff what is needed to get started. @native tide
The most important thing is to turn off the Debugging when you deploy / launch the web app
And Corey Schafer is in this discord server. I think??
Got alot of help from Corey's youtube videos
native tide
@elder nebula: Actually, i don't understand when he said that it's unsafe. How can Django can be unsafe with the default admin configuration?
That's don't make sense to me
What django gives me in the default admin configuration it's exactly what i need
but he make me scared telling me that's unsafe
@elder nebula : What do you mean with "if that project isnt going to public" ?
quiet solstice
Not exposed to the internet
native tide
The project is for a public institution
why i will make a project for not expose for the internet?
elder nebula
If its the default admin, then its pretty safe
steel tiger
With flask-restful, should I be splitting it up into diffrent files inegrated into my blueprints/components or should I make one large file for all of the API?
I would prefare the first one but not sure if is possible by doing it "cleanly"

Why did you change that?
You should NOT change any library code like that especially if you are a beginner
You should instead inherit the class in this case and put your template there
abstract basin
I changed because I was following a tutorial with django 1.10 and he has restaurant in url
And I wanted the same in url in django 2.1.7

If the tutorial changes library code stop that tutorial immediately
Inherit LoginView instead
And in the class that you inherit the LoginView change template_name
That's it

what is a good way to structure/run this project?

Anyone have best practice in dealing with abstract views in Django?
for example
class NoteAddView(LoginRequiredMixin, SubscriptionRequiredMixin, AjaxMixin, CreateView):
template_name = 'rental/standard_form.html'
form_class = NoteForm
def get_success_url(self):
return self.request.META.get('HTTP_REFERER', '/')
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['page_title'] = 'Add Note'
return context
class ContactNoteAddView(NoteAddView):
model = ContactNote
def form_valid(self, form):
form.instance.contact = Contact.objects.filter(pk=self.kwargs['pk']).get()
return supe r().form_valid(form)
I'm thinking this is the cleanest way to doing it but im feeling a bit unsure
if anyone has any other suggestions
tardy pasture
Are you going to be using NoteAddView elsewhere @full lynx ?
full lynx
Yes, for each model more or lesss
Have like a dozen xNoteAddView(NoteAddView)
@tardy pasture
tardy pasture
Without looking at things more in-depth, nothing you wrote gives me code-smell feelings.
@full lynx
maybe that space in supe r
but that's really just linting / typos.
full lynx
I ended up going with the above syntax yesterday and my subsequent children models look like
class LeaseNoteAddView(NoteAddView):
model = LeaseNote
form_class = LeaseNoteForm
def form_valid(self, form):
form.instance.lease = Lease.objects.filter(pk=self.kwargs['pk']).get()
return super().form_valid(form)
class LeaseNoteEditView(NoteEditView):
model = LeaseNote
form_class = LeaseNoteForm
class LeaseNoteDeleteView(NoteDeleteView):
model = LeaseNote
it looked tidy enough
tardy pasture
Do more of the inherited views have things like custom validation?
There's a couple of things that I would consider:
If it starts to feel boilerplate-y, then there's probably an optimization that you can make with the views. If you have a bunch of views where all you are doing is specifying models or form classes, you might be able to get away with a single view.
As a counterpoint, you might be over-optimizing; this is a pretty valid use of abstract views, and it gets the job done.

@uneven jasper if you are getting form in you gotta add in methods=['GET','POST'] within your route

native tide
How can you run flask on a particular domain?
vernal kraken
Wherever you host it you can configure the domain DNS to point to it
ie I use Heroku and when you add a custom domain it just gives you a string to point the url to
native tide
So I went thru the examples on deploying with heroku but im still confused on how to deploy using a certain url
candid basalt
@limber orchid I believe they are. Yet, you'd be better checking this out with their support. They are really nice.
limber orchid
yeah I finally heard back from them just now, they said as long as it's not in a static directory or being served to the user somewhere in the code, then it can't be seen
thanks!
candid basalt
@rough jasper I think you can filter by those with keys starting with HTTP_.
@native tide Domain and url are different things. Can you show an example of what are you trying to achieve?
native tide
basically what I want is instead of http://127.0.0.1:5000/solve I want it like http://dominus/solve
candid basalt
Is that for local usage only?
Or do you want it to be available to everyone in the internet?
native tide
everyone on my wifi network
candid basalt
That might not be easy. In that case you will need some kind of local DNS setup or make everyone adjust their hosts file and add record pointing to your IP address there.
native tide
I can get the hosts file edited
candid basalt
Everyone who is intended to be able to access the resource will have to do it.
Not just you.
candid basalt
In that case it's doable.
First you will need a static IP address.
I.e. DHCP won't work.
native tide
Can it be a vps server I rent?
candid basalt
As long as it's reachable via the static IP address - yes, sure.
Next xxx.xxx.xxx.xxx dominus line should be added into the hosts file for every client accessing the server, where xxx... is the IP address.
Start with yourself and see if it works.
native tide
Ok
candid basalt
Actually, IP address should be first. I've edited the message.
Obviously, you will have to set up your resource on that VPS you mentioned on port 80.
rough jasper
@candid basalt but referer doesn't start with HTTP_
native tide
Wait why port 80?
So basically edit my hosts file to xxx.xxx.xxx.xxx dominus and then start the flask server on that vps using localhost:80
candid basalt
http://dominus/solve has no port specified. This means default one is used. Default port for HTTP is 80.
native tide
Ahh ok
candid basalt
Yes, you pretty much nailed it.
@rough jasper is it not? https://docs.djangoproject.com/en/2.1/ref/request-response/#django.http.HttpRequest.META

no that gives me all the crap i don't want

REMOTE_ADDR doesn't start with HTTP_
i wan't to recreate http://azenv.net/
but local
within django
i am probably being stupid but it is kinda late
candid basalt
I think REMOTE_ADDR is not a HTTP header.
rough jasper
oh shit
candid basalt
At least I'm not sure if it has to deal with the protocol itself.
rough jasper
you're right
candid basalt
In any case if you want a given list of headers - you can just pick those you are interested in and output them.

i am stupid
i need to filter for HTTP_
and the otherones i have to just use the key itself

is there a way to return an image and json data in one response ?
using flask
native tide
I have a really basic html/php form system. The user can submit their name, and message. To prevent spam I want to add a "cooldown" like feature that disables the user from continually entering bs into my form. How would I go about doing this?
sharp briar
use ip or session or cookie
lost saddle
In your database or redis or whatever $_SERVER["REMOTE_ADDR"] save this and the creation time with the name-message
When the user sends another post request, check if the remote address is been used before, if yes check if it is still on cooldown( something like current_time - last_entry.time > cooldown: allow)
If not uhhh
return 429 or smt
This is just how would you do with ip I guess
You can use session or cookies but they are rather easier to create a workaround
candid basalt
@native tide I did not work with flask all that much, but it may depend on the command you use to run it with. It should accept connections from the public interface, not from 127.0.0.1
@maiden valley Don't ask to ask, just ask your question. =]
@jovial vapor It depends. You can try to return base64-encoded image as a part of your json response.
@native tide depends on the setup. You can save the time and date of the last message by username and check it for every new submit if it's recent or not.

So, I am trying to configure Flask + uWSGI + NGINX, and I used to be agle to route the app folder with @app.route('/'), and access it with www.example.com/myapp
but now it only works if I route it like this: @app.route('/'myapp/)
I tried a hundred thousand configurations for ini file and nginx 'sites-enabled/default'
including mounting the app with
manage-script-name = true
mount=/myapp=myapp:app
in the ini file, without success!
with previous apps I was using the "ugly hack" SCRIPT NAME = /myapp and uwsgi_modifier1 30; in the nginx default file
the only thing that differ from the methods is that I was using python 2 before, and now python 3, and I found this thread:
Any thoughts?

2 things
- Lets say I run a Flask server on Heroku. Is it possible that when I go to a specific url (on the flask/heroku server so like http://[my app name here].herokuapp.com/solve) it opens another tab on my browser?
browser as in the browser I used to go to the http://[my app name here].herokuapp.com/solve
- How can I set a custom domain for my heroku app? So I want the url instead of
http://[my app name here].herokuapp.com/solveit goes tohttp://dominus.com/solve. Is it modifying the host file?
candid basalt
@native tide
- Opens new tab when you visit the url by copypasting it into the browser address bar? Probably no.
- For services like heroku hosts approach may or may not work depending on how they handle incoming requests. There are routers involved, so it will probably not work without bought domain you own.
native tide
- Naa like using the webbrowser module. So I guess i go to http://[my app name here].herokuapp.com/solve and it does a redirect to another url
- So I have to get my own domain. Then what?

With 1) I'm still not sure I follow.
With 2) Heroku docs should have info how to do it. I did not work with Heroku all that much.

I'm trying to deploy a django website on a LAN network/intranet sort of thing. Right now the only way to access the site is through this address: 192.XXX.XX.XXX:8000, but I want others on the same network to be able to access it through putting 'intranet/' in a web browser, is it possible to redirect it?

Just ask your question @steel flicker
There are, but they may or may not be online and they're not going to reply unless they know what you're asking
@hallow ferry That sounds like a networking issue. You need to configure the client's DNS to resolve "intranet" to "192...".

So I'm trying to make an API with a database I have
I'm not really sure how should I structure the endpoints, though
let's say I have a list of users. As far as I understand, the endpoint /user should return the full list of users, while /user/user_id should return a specific user
however, what happens if the user list is really big? Wouldn't that make it too slow?
lost saddle
make it with pages
With filters
/user?sex=male&age=24&is_god=False&page_item_count=12&page=10

@dusk light , as @lost saddle mentioned, use pagination when you query and add it into the URL as a parameter. I'd suggest paginating on the database level instead of the client side javascript

Ok, sorry. Let me clarify some things.
I'm just trying to get information from a survey that I make and store it (I don't care how, I only need the data until the user gets the results.) Then use that data from the survey to pick a product from amazon and give them the link.
lost saddle
When does the user get the result
How does the user get the result
Where does the user get the result from

The user gets the result at the end of the survey.
They get a amazon referral link
They get the result from us, after our system decides what they should get based off survey informatin.
I'm just asking how I should store the data.
lost saddle
You don't store any data
You get it from the form
You put it inside your get_result_from_user_data function
And return the result
There is no storing involved
Everything happens in a view

Okay

Still though, any parameter like that would be optional for querying, so someone who doesn't specify any parameter like that would still have to deal with waiting

just as a comparison in the API I've made (which is just a flask-restplus hello world with a few modifications so it queries my database), querying a specific user takes about 20ms, while taking the whole user list takes 5 seconds
I understand that I can use parameters so queries can only get what they need, but my issue is what should I offer in the endpoint by default
Oh, wait
I misunderstood what you told me about pagination

I want to create image gallery like this. The rows are always equal and dont leave empty spots. I got it working, but the problem id that, I use django and the images gets uploaded with django, and the classes stay always the same, second problem was that the images stays always on the same row.
<div class='pics_in_a_row'>
<div class='img1'>
<img src='img1.png'>
</div>
<div class='img2'>
<img src='img1.jpg'>

<div class='img3'>
<img src='img3.jpg'>

```CSS
img {
width: 100%;
height: auto;
vertical-align: middle;

.pics_in_a_row {
display: flex;
}
.img1 { flex: 1.3344; }
.img2 { flex: 1.3345; }
.img3 { flex: 0.7505; }
.img4 { flex: 1.5023; }
.img5 { flex: 0.75; }
.pics_in_a_row {
margin: 25px 0;
}
.pics_in_a_row > div:not(:last-child) {

THIS IS CREATED BY Pat McKenna.So I need Javascript code or something to put the right flex class for the image, order to fit to the line.

Total noob: How do I call a function only after a specific event (uploading data) has been performed?
In Flask
kindred gate
make a request to a backend Flask URL with the function using JavaScript
cursive cairn
Could you give an example?
fathom prism
@cursive cairn , what kind of action are you attempting to perform? Is it a clientside UI interaction or a serverside processing action?
cursive cairn
@fathom prism Render some graphs upon uploading some data
fathom prism
@cursive cairn , is the user "uploading" data via a POST request to your web server and getting a HTML page or JSON response back?
cursive cairn
Uploading via POST. I want to upload data and render the graphs on the same page, directly after data has been uploaded
fathom prism
@cursive cairn, what framework are you using?
- User uploads to your endpoint /POST (e.g. /upload)
- <Do stuff to your file> (save to database, parse, etc)
- Return a JSON payload via ajax
- Have your javascript perform some sort of graph rendering
cursive cairn
Flask, Flask-Upload. Plotly.js for graphing.
fathom prism
The example on the flask upload doc is the exact one you could follow
@app.route('/upload', methods=['GET', 'POST'])
def upload():
if request.method == 'POST' and 'photo' in request.files:
filename = photos.save(request.files['photo'])
rec = Photo(filename=filename, user=g.user.id)
rec.store()
flash("Photo saved.")
return redirect(url_for('show', id=rec.id))
return render_template('upload.html')
https://pythonhosted.org/Flask-Uploads/
Replace the returns with a jsonify(your response)
cursive cairn
To render the graphs on the same page would I just redirect to the same page, but with new information?
fathom prism
No redirecting of pages needed. Your javascript would make an AJAX call to the /upload URL
cursive cairn
Oh wow. I didn't even know AJAX existed. Learn something new everyday. Thanks! 😃
fathom prism
Np, best of luck on your journey

Thanks!
Do you have any resources you'd recommend on learning to build webpages, specifically on Flask?

x = document.getElementsByClassName("img1");
$("img").each(function() {
height = this.naturalHeight;
width = this.naturalWidth;
ar = (width / height);
console.log(height + " x " + width + " = " + ar * 2);
var element = document.getElementsByClassName("img1");
for (var i = 2; i < element.length; i++) {
var element = document.getElementsByClassName("img1");
for (var i = 0; i < element.length; i++) {
element[i].style.flex = ar * 2;
};
};
});```So What I am trying to do, is get every images height and width. Then divide it (width / height) and put that in the div what is .img1
Example: Html <div class="img1"> <img src="butterfly.jpg"> </div> <div class="img1"> <img src="butterfly.jpg"> </div> <div class="img1"> <img src="butterfly.jpg"> </div> <div class="img1"> <img src="butterfly.jpg"> </div>
So put that image width divided by height to img1 div as a flex.
Output: <div class="img1" style="flex: 1.00 1 0%;"> <img src="butterfly.jpg"> </div> <div class="img1" style="flex: 1.00 1 0%;"> <img src="butterfly.jpg"> </div> <div class="img1" style="flex: 1.00 1 0%;"> <img src="butterfly.jpg"> </div> <div class="img1" style="flex: 1.00 1 0%;"> <img src="butterfly.jpg"> </div>
so the problem is:
It prints out the last third images height / width.

Hello, I'm currently trying to learn to use Flask and I'm trying to do so following best practices.
I am currently trying to add a bootstrap navbar and I want to give the template a list of links to add to the navbar. I want this navbar to appear on all pages of the site, but I'm not sure how to go about doing that.
From what I can tell I could create a list called navLinks or something and pass it as a parameter to the render template function, but I want it to be global & it seems like bad practice to add it to every call of the render template because the context that you pass should be specific to the page being rendered.
I have been working from this tutorial, http://flask.pocoo.org/docs/1.0/tutorial/, and I'm currently modifying things to use bootstrap and get a better understanding of how Flask works.
still briar
Are you using templates for your html? In that case you can create a base template that will always contain the navbar, which all pages include.
bold lichen
make your main page as template.html
then your other pages can reference that using
using the Jinja templating language http://jinja.pocoo.org/docs/2.10/
Pretty sure flask ships with it.
https://www.youtube.com/watch?v=QnDWIZuWYW0&index=3&list=PL-osiE80TeTs4UjLw5MM6OjgkjFeUxCYH&t=0s explains it i think.
@sleek tartan

Yes I am using templates
I have a base template that contains the following include
<header>
{% include 'base/navbar.html' %}
</header>
My navbar.html contains
<nav class="navbar navbar-expand-sm bg-dark navbar-dark sticky-top">
<a class="navbar-brand" href="#">
<img src="{{ url_for('static', filename='Images/nav_icon.png') }}"width="30" height="30" class="d-inline-block align-top" alt="">

</a>
<ul class="navbar-nav">
{% for link in navLinks %}
<li class="nav-item">
<a class="nav-link" href="{{ link[1] }}">{{ link[0] }}</a>
</li>
{% endfor %}
</ul>
</nav>
This currently works for the index page, but not any others.

Whats wrong with my quotation marks...?
In python the quotation marks make a string green. In html they're not. I'm using atom.
proper hinge
Doesn't mean something is wrong. They're different languages so Atom uses different syntax highlighting rules for them
Though the quotes for button look wrong
You should use the "straight" quotation marks instead of these ”
sleek tartan
I kind of figured out my issue.
In my init file I used a context processor
@app.context_processor
def inject_navList():
navLinks = {'links' : [{'name' : 'Home', 'url' : url_for('index')}, {'name' : 'Hello World', 'url' : url_for('hello')}]}
return dict(navLinks=navLinks)
That allowed me to access the dictionary without passing it to the render template function.
Anyone more familiar with flask know any best practices for where to declare context_processors?

Hello,
I like to create a website with flashcards, but I don't have idea how to create a models with it.
Do you think that such a thing makes sense?
from django.db import models
class FirstFlashcard(models.Model):
LANGUAGE_CHOICE = {
('PL', 'Polish'),
('EN', 'English'),
}
first_language_choice = models.CharField(max_length = 10, choices = LANGUAGE)
flashcard_text = models.CharField(max_length = 50)
class Meta:
verbose_name_plural = 'First Flashcard'
def __str__(self):
return self.flashcard_text
class SecondFlashCard(models.Model):
LANGUAGE_CHOICE = {
('PL', 'Polish'),
('EN', 'English'),
}
second_language_choice = models.CharField(max_length=10, choices = LANGUAGE_CHOICE )
first_language_text = models.ForeignKey(FirstFlashcard, on_delete=models.CASCADE)
second_flashcard_text = models.CharField(max_length = 50)
class Meta:
verbose_name_plural = 'Second Flashcard'
def __str__(self):
return self.second_flashcard_text
Why do you have two separate models? One for each side of the flash card?
native tide
@proper hinge I wanted to create one model, but I do not know how to make choice_field also contain the possibility of entering text (specific text to a specific language).
@proper hinge at the moment this is only a concept and I would like to come up with the most reasonable idea
proper hinge
I'm not familiar with Django forms honestly
But just from the perspective of model design having two models seems redundant
native tide
@proper hinge I think you have right. In that case, I must think how to implement it in one model in a logical way, right way.
proper hinge
Some ideas:
- In one model, make text fields for the front and back sides as well as language fields.
- Have one model with a single text and language field, then create a new model which "pairs up" two flashcard models using foreign keys.
Building on the first idea, instead of two language fields, you can have one that is like PL_EN or EN_PL so you can deduce the language of each side from a single field.
Though that doesn't work too well if you plan on having more than just those two languages
It's easier to add support for more languages when fields are separate
native tide
@proper hinge At the moment I focus only on two languages, but probably in the future I would like to add more
@proper hinge I will try to implement it in some way and share the result. Thank You for advice!
proper hinge
You're welcome

Why not have just one flashcard model without language select and just have il8n

When using flask, is there a wrapper that can be used for when a session is destroyed?
I'm looking for a way to clear temporary files after a user leaves
opal leaf
looks like there are a couple of options, but its limited because session expiration seems to be handled by the db backend
a) delete them when the user logs out/some other manual trigger
b) occasionally check which users have not done anything for a while and clean them up
c) figure out if the db backend you use has a hook for it
fading lake
There isn't a db backend, it's all going to be working with image files
However, I think I've found a workaround that should do just fine, I'll just need to do some restructuring
Essentially, what I was thinking was, front end / smaller web app I'm working on now (partially for a class) would AJAX files at this backend, which would save them, allow the users to pick a function on a different backend (one that I've already made), and then ajax to my backend which would call the other backend and then save that response and give the frontend a url to display that.
I've narrowed it down to the user will pick a function and upload the image in one go, allowing me to save it for as long as it takes to make the response, then wipe it (or just keep it in a temporary file object), and then save the new one and have the front end make a request when it's loaded and delete it serverside.
It's terribly thought out, but the deadline isn't for another few months and I'm already making pretty strong headway into this
opal leaf
yeah i would just not tie the activity to the session directly. decouple it and just let the session access the status and results of the activity.
if you find out the user wont come back to download the file you can delete it, but otherwise just let your system process it and the user check any status/results by loosely associating their session with the activity [eg via an id]
this way you can just say 'all files created will be deleted within 1 hour' and if the user downloads it or not you still know its time to delete it
fading lake
Yeah that might be another good approach
I've never really dealt with file uploading or temporary files, so this is good practice

I just asked which is the best practice to do it, in the front end (react native app) or the backend (django api server)

Ah ok. I just do it on the frontend, and if its valid it commits the hash to DB:
email = StringField('Email', validators=[DataRequired(),Email()])
username = StringField('Username', validators=[DataRequired()])
password = PasswordField('Password', validators=[DataRequired(), EqualTo('pass_confirm', message='Passwords Must Match!')])
pass_confirm = PasswordField('Confirm password', validators=[DataRequired()])
submit = SubmitField('Register!')```im trying to override the allauth default template. The docs say For instance, the view corresponding to the account_login URL uses the template account/login.html. If you create a file with this name in your code layout, it can override the one shipped with allauth. Is this saying i create a module called account and a template in it called login?

any pointers in the right direction would be appreciated 😛
figured it out, e.which to e.key in the javascript
follow up question.... how do I debug javascript

Are there any guides you guys recommend for learning HTML/CSS?

Can someone help me clear my confusion? I am trying to render graphs on a page after the user uploads data. I have a bunch of functions in Python that make the json needed for rendering the graphs using a Javascript library. What would be the most efficient way to pass uploaded data to my python functions and then the JSON back to Javascript without reloading the page? I assume I'll have to use AJAX?
unborn terrace
@cursive cairn if you do not want to reload yeah you have to use AJAX (or Websockets or stuff like that, but will be overkill).
You are probably better off simply reloading the page, that is not so bad tbh
cursive cairn
How do I send data from AJAX to Flask, run some functions, and then pass the data back without reloading?
unborn terrace
@cursive cairn create a Flask view that receive data (from a form or JSON for instance) and returns new data
And send a request to this view from within the page, using AJAX for instance
cursive cairn
yeah im refreshing the page

I'm making a progress bar..
is there anyway I can make it look cooler

Is there a easy spinup for django? Like generic setup
Ive worked with php etc (drupal) for.. last decade.. Django sounds nice
rancid junco
I know this is silly, but I am trying to learn js, but I am a tad confused. So I made a json file that contains jokes, and I would just like to simply "lists " them on a site, like I want the question and answer to just show up in the center of the screen, and after a wait time, then show the next joke. Any idea how I can do this?
also these are the jokes
I just took them from the programming dad jokes github page, and turned them into a json file
rancid junco
nvm I think I figured it out
rancid junco
Nope
so does anyone know the best way to show two values, have a wait time, then show the next two in the json?
the wait time is not issue, its the showing the values

how do i send POST data without a form
@quaint ledge http://flask.pocoo.org/docs/1.0/deploying/#deployment
radiant river
the django docs say
allauth ships many templates, viewable in the allauth/templates directory.
For instance, the view corresponding to the account_login URL uses the template account/login.html. If you create a file with this name in your code layout, it can override the one shipped with allauth.
so to override the all auth html do i create a module called account and a file called login .htm

I'm a tad confused about backend web dev languages. How does a non OOP language like Python or JS work with back end stuff? Like I guess I'm just not seeing the capabilities of a scripting language besides making little kiddie scripts
grand musk
untold zealot
yeah nvm I'm an idiot
quaint ledge
@teal scroll which self deployment option is the best? the descriptions arent that helpful
quaint ledge
what do cloud services mean when they say "instances"?
fathom prism
most likely a virtual machine
junior cloak
@untold zealot haha kiddie scripts, really? tell that to instagram, youtube, the entire machine learning and data science industries, the entire visual effects industry, many other things, etc. like any language there are areas in which it excels and areas in which it does poorly than others. and also like anything else, it's also dependent on the skill level of its user
@quaint ledge yes "instance" refers to a single virtual server of some sort. regarding deployment -- which is the "best" depends on your needs. do you already use aws or heroku or any of those? is there a budget for this project? do you want something that's easier to work with or more painful but cheaper? etc
quaint ledge
oh ok
junior cloak
@quaint ledge oh sorry, you said self-deployment. okay that's different, one can safely say that gunicorn + nginx is key
i would not bother with those other choices
quaint ledge
i decided to go with a virtual server
digital ocean
it seems good
seems cheap too
junior cloak
except that i am a huge fan of Caddy as a web server that is dead simple to use and performs about 80% as well as nginx and so yeah
DO is fine
is this for fun or work or intended to be running in production with users and whatnot soon
quaint ledge
its for fun
junior cloak
DO is fine, the obvious downside with any vps provider is that you now have to run the vps and all the crap on it
which is why i love heroku to death and use it for everything in development, but its costs are not conducive to growth in production
however its free tier is more than adequate for most projects while they are in development and then your entire deploy process consists of running git push heroku master rather than configuring a vps, linux, nginx, gunicorn, everything else
it's all tradeoffs depending on needs and goals and resources
quaint ledge
the free tier didnt seem that great and i think $5 is a good price for what im getting
and i dont really have a problem setting it up
junior cloak
for heroku? if you had lots of usrs it would be a problem because heroku's free tier has to spin the application down when it isnt being used much, so in production it wouldnt work. but in development it works fine since presumably you arent using the app for 24 hours each day
and when i am using it with the free tier and free postgres db it can still handle a couple thousand active [simulated] users
quaint ledge
id prefer it to be up all the time
junior cloak
but anyways
yeah totally, just asking. sometimes simplicity is important for people
then yeah the de facto thing to do would be ubuntu instance, nginx web server proxying to your python app which is using gunicorn
i would still perhaps recommend caddy because you can go from never having touched it to a production-ready server for your python app and automatic ssl in less than 10 lines of configuration and a few minutes
nginx is certainly the standard and is fantastic but it's much more complex
vagrant adder
guys i am making a little CRUD twitter-like app
where can i find ideas for user account html files
this is it for now
junior cloak
@vagrant adder ...as in like, design inspiration? or as in you know how it should look but not sure how to implement it? if it's the latter, then you need to either take a step back and dive into html/css, or you should use a ui library (bootstrap, bulma, whatever) that already has the html/css made and you just have to put them where you want
vagrant adder
it's just that i'm not a creative soul
junior cloak
yeah that's the age old question, how should it be designed? and theres ever a perfect answer
i of course make note of how things are laid out that i think are welll done
and i spend lots of time on dribbble and visiting various design inspiration lists
vagrant adder
i thought of wix but wix is essentially markerstore template list
junior cloak
you thought of wix as in... you like how their user profile pages are designed? or what
wix does have some pretty well designed stuff on occasion
steel tiger
I have a view with an int at the end in routing, for example: ```py
@app.route('/some_view/int:id')
def some_view(id):
return f'Example result for id: {id}'
The only problem is that I would like to check in templating if the path is `/some_view/<int>` but do not know how to.Basically what I need to do: ```py
if request.path == url_for('some_view', id=[NEED THIS]):
It will detect if the ID is anything.
The thing I am trying to achive is a navbar so I have to do it in templating FYI
steel tiger
Nobody? :(
vernal kraken
@steel tiger like pagination? You can grab a bootstrap example and there are a bunch of tuts on how to set it up with flask or Django

hey @junior cloak, do you know what they mean in this pic by "app key"?
junior cloak
@quaint ledge where on earth are you finding these tutorials
quaint ledge
DO
junior cloak
even this little snippet looks strange
but to answer your question
the secret key is just any random, hard to guess string
doesnt matter what it is, nor do you have to remmember it
just a very long intense password
it's used when flask needs to secure the cookies, sessions, etc
quaint ledge
where do i uhh get it
