Hi, a little confused by the action attribute in my <form> in flask. After I submit the form it renders the index page but it doesn't have my flashed message, it just says "Hello Index Page." I have the index page as the action, so shouldn't it display my flashed message?

routes.py

def login():
    form = RegistrationForm()
    if form.validate_on_submit():
        flash('Registration requested from user: {} and remember_me: {}'.format(
            form.username.data, form.remember_me.data
        ))
        print("True")

        #return redirect("/index")
    
    print("False")
    return render_template("login.html", form=form)

@app.route("/")
@app.route("/index", methods=["GET", "POST"])
def index():
    return render_template("index.html")```

index.html
```  <body>
        <h2>Hello Index Page</h2>
        {% with messages = get_flashed_messages() %}
            {% if messages %}
                {% for message in messages %}
                    {{ message }}
                {% endfor %}
            {% endif %}
        {% endwith %}
    </body>
</html>```

login.html

<body>
    <form action="/index" method="POST">
        {{ form.csrf_token }}

        <p>{{ form.username.label }}<br>
            {{ form.username(size=32) }}
        </p>

        <p>{{ form.password.label }}<br>
            {{ form.password(size=32) }}
        </p>

        <p>{{ form.remember_me() }}
            {{ form.remember_me.label }}
        </p>
        <p>
            {{ form.submit() }}
        </p>
    </form>
</body>```

I had more of a design question relating to user authentication/authorization rather than a programming one. Is there still a use case for session based authentication? I know that JWT / OAuth2 is fairly mainstream for larger applications, but I was thinking about using sessions for my smaller (pretty much a SPA) project.

#

I assume since I am only consuming the backend from 1 source (the web app), and since there will be not many users, session based auth would be okay for my use case but wanted to see what you guys thought.

@blissful lion Absolutely.

glass sandal May 27, 2020, 4:51 PM

#

Guys why aren't u guys chatting bout Django?

tired root May 27, 2020, 5:16 PM

#

@glass sandal Because everyone is using Flask

glass sandal May 27, 2020, 5:16 PM

#

But y not Django?

#

It's better

#

Cooler

#

Batteries included

tired root May 27, 2020, 5:17 PM

#

Because it is often overkill for tasks where you need little overhead

#

There is no "this is better", there is only "this is more suited to the task" in professional IT

#

gotta leave emotions out and concentrate on facts and requirements

glass sandal May 27, 2020, 5:22 PM

#

Django has more job offers

#

Almost 100% more than Flask

obtuse crypt May 27, 2020, 5:23 PM

#

👍

glass sandal May 27, 2020, 5:23 PM

#

Django is a 1 package including all not like flask_admin , flask_sqlalchemy and ...

#

Django does this itself

#

And since it's rated 2nd in top backend frameworks , it's better than flask that is 5th

tired root May 27, 2020, 5:24 PM

#

@glass sandal What is your problem here? Do you want to sell us on something?

#

I stand by what I said

glass sandal May 27, 2020, 5:24 PM

#

So do I

#

So

tired root May 27, 2020, 5:25 PM

#

Why are you arguing at all? If you came here to stir up trouble, then this is the wrong discord for that

glass sandal May 27, 2020, 5:25 PM

#

I just said it's cooler and you didn't accept

tired root May 27, 2020, 5:25 PM

Not get lost in pointless like-wars

glass sandal May 27, 2020, 5:25 PM

I rarely see any django in this channel

I was confused

So I asked

tired root May 27, 2020, 5:26 PM

Then you aren't here enough

glass sandal May 27, 2020, 5:26 PM

I've been here for last 8-7 months

tired root May 27, 2020, 5:26 PM

but anyway, I am going to stop replying, this discussion is pointless

glass sandal May 27, 2020, 5:26 PM

#

Yeah sorry for taking your time anyways

obtuse crypt May 27, 2020, 5:27 PM

#

@tired root - I agree. I find myself going down rabbit holes when I'm trying to learn a topic, or I'm bombarded with this framework , that framework, or package and it just confuses the hell out of me and I end lost and lose interest

glass sandal May 27, 2020, 5:27 PM

#

Yeah that happened to me alot too

obtuse crypt May 27, 2020, 5:27 PM

#

We have to stick with a topic

tired root May 27, 2020, 5:27 PM

#

Again, it's all about requirements. There are cases where Django is the choice and there are cases where Flask is the choice. To compare them head on is pointless and moot

obtuse crypt May 27, 2020, 5:28 PM

#

Agree

tired root May 27, 2020, 5:28 PM

#

Flask is really light-weight and runs nicely on my pi for example, for my radio project

#

for a big website I'd go with Django

obtuse crypt May 27, 2020, 5:28 PM

#

It's all about Fit for Purpose

glass sandal May 27, 2020, 5:28 PM

#

Want a Medium - Big project ? Go for django. Have a small - medium Project? Flask is the choice

#

I get it now

tired root May 27, 2020, 5:29 PM

My radio for example was made in Flask

glass sandal May 27, 2020, 5:29 PM

Nice !

obtuse crypt May 27, 2020, 5:29 PM

#

That is nice. I like the color scheme

tired root May 27, 2020, 5:29 PM

#

It runs on a Pi on my nightstand with a touch screen and it also serves the interface to my network

glass sandal May 27, 2020, 5:29 PM

#

It's cool

#

You built it with Flask_websocket right?

obtuse crypt May 27, 2020, 5:30 PM

#

@tired root, You got my gears spinning now for Pi projects

tired root May 27, 2020, 5:30 PM

#

No, flask is only used for the web interface and backend

#

The bars come from Javascript Media API

#

well, it's a HTML5 canvas

glass sandal May 27, 2020, 5:31 PM

#

Ik I mean the backend

tired root May 27, 2020, 5:31 PM

#

but I load the stream with javascript and use the fft acquired from media api to display those bars

glass sandal May 27, 2020, 5:31 PM

#

Oh I get it now

#

Well , you're a fullstack developer right?

tired root May 27, 2020, 5:32 PM

#

I am not a developer at all

#

Ummmm

📎 unknown.png

glass sandal May 27, 2020, 5:32 PM

#

You built a radio using Flask and JS

#

And you're not a developer?

tired root May 27, 2020, 5:33 PM

#

no

#

I work in a data center as Network Administrator, I mostly deal with cables, routers and traffic

glass sandal May 27, 2020, 5:33 PM

#

Oh

#

I see

tired root May 27, 2020, 5:34 PM

#

The most challenging part was the system level scripting actually

#

to make the networking changes etc

glass sandal May 27, 2020, 5:35 PM

#

Oh

tired root May 27, 2020, 5:35 PM

#

and fix the lazyness of radio stations

glass sandal May 27, 2020, 5:35 PM

#

The low level stuff is done with C/C++ . How did you do it in Python?

tired root May 27, 2020, 5:35 PM

#

There is no C++ involved

#

it's just changing config files

#

and restarting services

glass sandal May 27, 2020, 5:36 PM

#

Oh I see

tired root May 27, 2020, 5:36 PM

#

A specific user can run certain scripts with sudo without password

#

that is all the magic

glass sandal May 27, 2020, 5:36 PM

#

Ohhh

#

Nice

#

gj . But you're a developer

tired root May 27, 2020, 5:37 PM

#

I am really not. I am just an idiot with too much free time

glass sandal May 27, 2020, 5:37 PM

#

And in that free time , you turned into a developer

obtuse crypt May 27, 2020, 5:38 PM

#

Quarantine has created some free time for many of us

glass sandal May 27, 2020, 5:38 PM

#

Lol yeah

#

But school holds me back a bit

#

Like we have final exams

#

So

#

Anyways

#

nvm

tired root May 27, 2020, 5:39 PM

well, data centers are critical infra, so.. I still have to go to work

#

@tired root offtopic but what type of background is needed for that line of work?

tired root May 27, 2020, 5:57 PM

#

@blissful lion I'd say that depends on the company. I have a normal IT background, no special training. Should have some networking knowledge though. Like subnetting, IPV4 , IPV6, know how to read tcpdump and other things

#

maybe also have worked with real routers/switches

#

as in, Cisco/Juniper

blissful lion May 27, 2020, 5:58 PM

#

gotcha, I'm going to school for a BS in Info Systems and an MS in Comp Sci, I really enjoyed my networking course and was thinking about getting some cisco certs myself

tired root May 27, 2020, 5:58 PM

#

and know your way around Linux. Nobody uses Windows in that field

blissful lion May 27, 2020, 5:58 PM

#

I have my own dell r710 server at home for some general automation, seems like a really interesting field to get into

tired root May 27, 2020, 5:58 PM

#

That is sysadmin

#

my work stops at the last switch

blissful lion May 27, 2020, 5:58 PM

#

ah, you do more networking gotcha

tired root May 27, 2020, 5:59 PM

#

well.. it's called Network Admin for that reason

blissful lion May 27, 2020, 5:59 PM

#

haha true

tired root May 27, 2020, 5:59 PM

#

I manage switches and routers and their components, there is no copper in what I do, only fibre

blissful lion May 27, 2020, 5:59 PM

#

I wish I could find an internship for a datacenter just to get a feel for it, but I'm not sure any companies would really have those :P

tired root May 27, 2020, 5:59 PM

And about 8000 of them

blissful lion May 27, 2020, 6:00 PM

#

dang thats pretty cool

tired root May 27, 2020, 6:00 PM

#

we have data centers in multiple European Cities and POP all over Europe

blissful lion May 27, 2020, 6:01 PM

#

that's awesome.

tired root May 27, 2020, 6:02 PM

#

Cisco certs are kind of overrated IMHO. From what I know, nobody in my office has CCNA

#

but then, we are using Juniper

blissful lion May 27, 2020, 6:02 PM

#

yeah, I kind of feel like some of the certs aren't that useful

tired root May 27, 2020, 6:03 PM

#

it depends on why you do them. If you really want to learn, they are great. but many places offer brain dumps, only teach what is to know to beat the test

blissful lion May 27, 2020, 6:03 PM

#

so I guess if I wanted to get into that field I'd probably just want to get a few routers / switches to mess around with eh?

tired root May 27, 2020, 6:03 PM

#

Most only have them as decoration for their CVA

#

You don't want to get the routers we use

#

first of all, they are loud as fuck

blissful lion May 27, 2020, 6:03 PM

#

yeah i bet they get pricey too

tired root May 27, 2020, 6:03 PM

#

second, they set you back a couple of ten thousand

blissful lion May 27, 2020, 6:04 PM

blissful lion May 27, 2020, 6:08 PM

#

fair enough 👍

zealous siren May 27, 2020, 6:24 PM

#

Off topic but CCNA is not something I’d recommend. More and more is going SDN

tired root May 27, 2020, 6:24 PM

#

@zealous siren Maybe in the developer world, not in the networking world

zealous siren May 27, 2020, 6:26 PM

#

In general, I’m from sysops SRE field

tired root May 27, 2020, 6:27 PM

#

The infrastructure on which all your virtual stuff runs, is old fashioned networks, because the Internet runs on it and needs it. All the things like SDN is layer 7 additions

#

So, if one works in the data center world of networking, these things are meaningless because my job ends before any of my cables come near any server

zealous siren May 27, 2020, 6:27 PM

Ot2?

tired root May 27, 2020, 6:28 PM

sorry I stop

pale radish May 27, 2020, 6:54 PM

#

Does it make sense to obfuscate API calls between a framework like Angular and flask? I'm trying to figure out a way for users not to abuse the API.

tired root May 27, 2020, 6:58 PM

#

@pale radish no

#

Because you need to deobfuscate it in js anyway

#

and js is user side

#

so save yourself the trouble

#

better idea is to cache, than to limit

#

use e-tags, so the content is only updated and resent if something actually changes

#

otherwise 304 is sent

pale radish May 27, 2020, 7:00 PM

#

Thank you, I'll take a look at this. Have never made a production site but am trying to.

tired root May 27, 2020, 7:17 PM

#

@pale radish https://flask-rest-api.readthedocs.io/en/stable/etag.html

#

as a starter

zealous siren May 27, 2020, 7:22 PM

#

agingbones, if abuse becomes a big problem, you will have to build anti abuse systems like looking for consistent calls, also requiring tokens and doing token expiration helps as well

tired root May 27, 2020, 7:22 PM

#

drop the first tcp packet of every incoming connection

#

at your firewall

#

it must support flows though

zealous siren May 27, 2020, 7:23 PM

#

We found websockets help just because they are harder to automated

tired root May 27, 2020, 7:23 PM

#

first packet of every tcp connection is S

#

think about what happens if you drop it

zealous siren May 27, 2020, 7:24 PM

#

another Syn is sent?

tired root May 27, 2020, 7:24 PM

#

correct

#

but only if the sender was serious about the connection

#

ddos tools don't work like that

#

or amplification attacks

zealous siren May 27, 2020, 7:24 PM

#

that's dumb as anti abuse setup and most requests libraries will handle that

tired root May 27, 2020, 7:24 PM

#

it maybe dumb but it's very effective

pale radish May 27, 2020, 7:24 PM

#

Hmm, okay, I'll just have to research more into it before I release to production. I don't have any users or sensitive data, but I don't really want all of the data I manually inputted to be mined instantly.

zealous siren May 27, 2020, 7:24 PM

#

I think they are worried about people using the APIs outside a browser

#

it will be

#

selenium will see to that easily

pale radish May 27, 2020, 7:25 PM

#

How do people protect against that or do they not?

zealous siren May 27, 2020, 7:25 PM

#

it's pretty difficult to stop

pale radish May 27, 2020, 7:26 PM

#

I just imagine there's a lot that I don't know about in regards to web frameworks that I'll massively fuck something up when I release

#

But I'll just research into more flask restful prod guides

#

and caching

zealous siren May 27, 2020, 7:26 PM

#

We do SPA with REST API, caching/token expiration

#

there is also API Gateways that will help but they cost money

#

useful for business, not so much individual

pale radish May 27, 2020, 7:27 PM

#

Where can you host SPA, API, MongoDB?

#

Heroku?

zealous siren May 27, 2020, 7:27 PM

#

SPA is all Javascript so anywhere you have static HTTP engine

tired root May 27, 2020, 7:27 PM

#

@pale radish Speaking of amplification attacks, make sure there is no path that release mass amounts of data

#

because otherwise it will be used for amplification

pale radish May 27, 2020, 7:28 PM

#

Good idea, thank you, I'll research into protecting against that as well because I do have a few API calls that have quite a bit of data being returned

#

Looks like Heroku does have Mongo, but barely any space...

tired root May 27, 2020, 7:30 PM

#

Another idea is also to generate a key based on IP and a web beacon, such as the famous browser pixel

#

and use that one as a api key

#

it may not stop the real hackers, but the script kiddies probably

pale radish May 27, 2020, 7:31 PM

#

How do you all do storage in the cloud? without spending a fortune?

tired root May 27, 2020, 7:31 PM

#

not sure how effective that really is though

#

My cloud server costs 5 bucks a month with 20 TB traffic and 20 gb storage. Not sure how much you need

#

you can get 100 gb for about 4 bucks

#

1 tb for 40

Guys how would you create login system without wtforms?

#

With wtforms it seems more complicated than it should actually be

rustic pebble May 27, 2020, 10:14 PM

#

You can use a JWT

#

user puts credentials -> you verify credentials -> you said a JWT -> you use the jwt to identify the user

pulsar ivy May 27, 2020, 10:17 PM

#

I was wondering will basic input field work?

#

I have database

#

I have registrate page

#

That works

rustic pebble May 27, 2020, 10:17 PM

of course

pulsar ivy May 27, 2020, 10:17 PM

Wait would sending a int trip it up?

#

Nope, sending a stringified int didn't change it.

Still trying to send batch as a "file"

Hi

#

If I wanted to have a dropdown selection that would query data from a DB and populate matching terms in an HTML table, how would I do that?

#

I already have a DB that does plenty of queries, saving to and from the DB. So the DB and most other functionalities, like an admin page, forms etc. They all work on my Flask project along with templates.

#

I use SQLite, Flask, wtforms

#

I just don't know how to do the opposite of that, which is, have a dropdown selectfield, that once chosen, would populate a table beneath it with matching results.

I have a database with articles. Like, Articlename, Price, Description, Photos etc. Now im using flask with jinja-templating. When I want to display each article, I just do:

{% for item in article %}
  item.item['articlename']
  item.item['articleprice']
  <img src="https://loremipsum.com/{{ item['articlephotos'] }}">
{% endfor %}

Now when I have more than one photo I run into problems.
Right now I have Links of these photos in the DB like this:
(All links in one attribute and with comma seperated)

/static/images/artikel_1.jpg, /static/images/artikel_2.jpg, /static/images/artikel_3.jpg

Of courseI can seperate all these links and add to a new List but then they are not assigned to a single article anymore. All links of whole table are in that array.

Should/must I make a new attribute for every photo in my table?

Currently I'm experimenting, and I've made a couple endpoints for User and Group objects using the django rest framework's tutorial. I wanted to make a frontend list view that uses the user endpoint instead of directly using the User manager. I did get this working using the requests library. However, there's an incredibly large speed difference between hitting the endpoint directly in a browser, which returns in something like 20ms, and the requests.get('<endpoint url>') which takes something like 2-3 seconds. The relevant snippets of code, though I've done the requests.get() call in a terminal and also got the same speeds, so I imagine that specific line is the issue.

class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all().order_by('-date_joined')
    serializer_class = UserSerializer
    # permission_classes = [permissions.IsAuthenticated]


class TestConsumeJson(ListView):
    template_name = 'quickstart/list.html'
    context_object_name = 'user_list'

    def get_queryset(self):
        response = requests.get('http://localhost:8000/users.json') # Why is this part so slow? 2 whole seconds?
        users = response.json()
        return users['results']

#

I guess for completeness, the template is just this simple thing, which functions as expected and I don't expect it's problematic:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Lists</title>
</head>
<body>
    <h1>Lists works</h1>
    {% for user in user_list %}
        <p>{{user.username}}</p>
    {% endfor %}
</body>
</html>

#

Any ideas on why this slowdown is happening, or ideas on what I can check to investigate?

dry raft May 30, 2020, 5:52 PM

#

Additional information: The headers sent with requests.get are {'User-Agent': 'python-requests/2.23.0', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive'}, and send a request to http://www.google.com with requests.get, using the same default headers, is not slow. I tried sending Connection: close due to a stackoverflow post I saw, but that didn't seem to help in my case.

I have an input in my html file (doesn't make a difference if it's in a form or not)
<input type="search" class="monster-search" name="monster-search" id="monster-search">
I get each character typed by jquery
$('.monster-search').on('input', function() {
var monster_id = Number($('#monster-search').val());
console.log('.monster-search called with id ' + monster_id);

    //Send value to database and get monster information
    $.ajax({
       url: '/',
       type: 'POST',
       contentType:'application/json',
       data: JSON.stringify(monster_id),
       success: function(response) {
           console.log(response);
           //generate html to show result list in a div
       },
       error: function(error) {
           console.log(error);
       }
    });
});

In my app.py I get the data
if request.method == 'POST':
monster_id = json.dumps(request.get_json())
...do stuff with it and return...
return jsonify(monster_result=monser_data_reformatted)

#

hmm. it seems that adding event to the ajax function call and
event.preventDefault();
event.stopImmediatePropagation();
fixed it but why would it be posting in addition to the ajax call when there's no form being submitted?

Have you tried the autoplay attribute of the audio tag?

Keep in mind: users are not particularly fond of autoplay music or videos. And browsers are moving to disable allowing it (if they haven't already).

When you’re displaying image content with headers and you send the url (for example web.site/image.php)

Discord will show the image as intended. But it also caches it regardless of any cache headers. Any way to stop that?

cyan kettle May 31, 2020, 6:41 AM

#

change the url to something like /image/randomstringlikeanuuid
then configure your routing to serve the image to any requests starting with /image or whatever you chose

#

there's also a clever method using url parameters for example

Hello everyone, can someone explain me or give some resources about hosting a web app made in flask? I have previous expierience with PHP programming making websites ant hosting them is very easy and not expensive, but now I fell in love with python and flask and i tried to host my app on raspberry pi using docker (following advice form user from this discord) but it seems it is not possible becouse of some docker modules aren't aviable on raspberry pi. I started to look for some other solutions and it looks like its only possible on big services like azure aws etc. but they are pretty expensive, and i wonder why is that? Is there a cheap way to host/deploy a flask app? Wish you all health!

verbal obsidian May 31, 2020, 9:26 AM

#

@normal vapor Check out, digitalocean, scaleway and companies as such's tutorials, they have many tutorials on how to deploy apps in vpss, these

#

are rather cheap, I use them alot for testing, can be as cheap as 3.5€ per month

#

Also you can definetely deploy flask apps in your raspberry pi, I'have done that many times

normal vapor May 31, 2020, 9:29 AM

#

When you deployed on raspberry pi, were you using docker or just on the base system?

verbal obsidian May 31, 2020, 9:29 AM

Docker

#

as of right now, I have 1 discord bot, 1 ngrok instance, 1 postgreesql cluster and 1 django app

About django user, should i use allauth or develop from scratch a custom user model. Allauth has a lot of features, and save time. I can allow users to login with socials network, email system features, built-in views, and more... But is it worth? Or should i develop from scratch? I dont know... someone can help me?

#

Im reading about it, and seems to be a nice ways to manage users

cold anchor May 31, 2020, 5:59 PM

#

Don’t do it from scratch if you don’t need to. If allauth provides what you need, use it

dark hare May 31, 2020, 6:03 PM

#

Good practice in django is to always use a custom user model before your first migration to make it easier to customise later on down the line. You shouldnt be writing a user login library from scratch, allauth provides pretty much everything you could want

What's best practice when it comes to Django/flask? Like where do you keep your web app's code itself. Currently on my first project I have my code in my flask's main.py file where I also hold my flask routes etc. Is it okay to keep it in there or should I split it off into it's own file and then import that into my main.py file?

@fiery tapir Flask I'm not sure on since I've only done a bit of it and have a narrow experience, but django has a pretty decent tutorial on the website. It'll walk you through a small project and should help you get a feel for what stuff goes where. It's sort of a lot initially, but give it a go and come back with questions!

Subscriptable means whether they implement the _getitem()

method

using [ ] calls that method

in that context

up to you
@quasi ridge That is not really true, splitting up the views and the functions into services, helpers, views and more is crucial to building a correct hierarchy in which you can develop and maintain the product without having to go through hours of understanding your code. Having a main.py file contain only a small number of lines that really just launches the web server is ideal

@native tide

autoescaping is enabled for all templates ending in .html, .htm, .xml as well as .xhtml when using render_template().
from https://flask.palletsprojects.com/en/1.1.x/templating/

#

Since you brought up .txt

#

ohh let me look at thi ty

#

all i was really looking for was a way to make it visually obvious from looking at files what is being included how. I use inheritance, overriding blocks, and inclusuion

#

Ah, gotcha. Then yeah you'd want to pay attention to the extensions.

#

Would a better way not just be to to batch markdown all the mds at runtime and then include generated html to avoid that

#

having to do autoescaping

#

that is

#

You can enable escaping as well

I think its possible that Flask takes it out of the ballpark with homerun win for error messages that are never helpful and full of useless information lol

quick cargo Jun 1, 2020, 7:06 PM

#

i get hardly any errors with flask tbh

#

and theyre normally very readable

dark hare Jun 1, 2020, 7:15 PM

#

what errors are you getting?

native tide Jun 1, 2020, 8:05 PM

#

Its typically issues with templates. i think.

#

Otherwise they arent that bad.

#

Im not having any atm but they arent very descriptive. They have a way of showing me something completely unrelated to the problem, and a lot of what they show is code i didnt even write so if tits the problem then there is something wrong deeper than my implemenation

#

sometimes you can make sense from it if you only read the top [art and ignore everything else it shows you

#

it might be more accurate to say that is a jinja2 thing

@native tide You should run pip directly in the terminal, you are currently inside of the python repl.

You can type exit or press control + D to leave it.

you've defined a tuple named errors on (I think) line 3.

See it?

Then later you use it as a decorator, Lord only knows why.

decorators gotta be functions, not tuples.

Does anyone know of a way to expose flask/aiohttp, assumedly the target machine will have to have a static ip registered in their router

Hello everyone, Hope you are doing well.

I am building a website with django which will be used to view different documentation related to the construction industry, in an easy to use and share format.

The main viewer page will have a vertical nav bar with different chapters and sections. And the right side will be the content.

What I am trying to figure out is instead of doing a hardcoded HTML css static file, use the database to create a html file . What do you think is the best way to go about ir. I thought about it a lot and the problems I see is where there are lists/tables/images in content. I am having a hard time deciding what models should I create.

Hello everyone.
A quick question: I'm developing a website/app with Flask with dozens of pages. What's the best way I can keep a consistent css style? Like have themes, be able to change colors quickly, compile colors from a palette.
I have had previous experience with drupal and scss, I don't know if it's applicable here.

fossil thicket Jun 2, 2020, 10:51 AM

#

i have a couple of colours and want to generate a scheme from them, any good suggestions on tools to use?

cloud path Jun 2, 2020, 11:05 AM

#

guys, can i specify a maximum file size besides FileAllowed?

class UpdateAccountForm(FlaskForm):
    email = StringField('Email', validators=[DataRequired(), Email()])
    pic = FileField('Carica l\'immagine di profilo', validators=[FileAllowed(['png','jpg'])])
    cover = FileField('Carica la cover del profilo', validators=[FileAllowed(['png','jpg'])])
    submit = SubmitField('Aggiorna')

cloud path Jun 2, 2020, 11:45 AM

#

done i think but i've another issue

#

            picname = secure_filename(form.pic.data.filename)
            pic_path = os.path.join(app.root_path + '/static/profile_pics/' + picname)
            form.pic.data.save(os.path.join(pic_path))
            current_user.image_file = picname

the image that i upload saves itself with its own name as i was not using secure_filename

native pasture Jun 2, 2020, 11:56 AM

#

            picname = secure_filename(form.pic.data.filename)
            pic_path = os.path.join(app.root_path + '/static/profile_pics/' + picname)
            form.pic.data.save(os.path.join(pic_path))
            current_user.image_file = picname
the image that i upload saves itself with its own name as i was not using secure_filename
@cloud path what secure_filename should do is just remove reserved characters and make the filename safe for storage (ie. remove slashes and so on). Were you intending to do something else?

cloud path Jun 2, 2020, 11:57 AM

#

oh no i thought it was a number generator for the filename

#

but

#

what if a user uploads two pictures with the same name?

native pasture Jun 2, 2020, 11:58 AM

#

You're probably looking for a uuid or hashing function (+timestamp) then. I would go for the former.

cloud path Jun 2, 2020, 11:58 AM

#

alright

#

thanks

Asking good questions will yield a much higher chance of a quick response:

• Don't ask to ask your question, just go ahead and tell us your problem.
• Don't ask if anyone is knowledgeable in some area, filtering serves no purpose.
• Try to solve the problem on your own first, we're not going to write code for you.
• Show us the code you've tried and any errors or unexpected results it's giving.
• Be patient while we're helping you.

You can find a much more detailed explanation on our website.

@heavy patio what do you need help wit

@solar obsidian
Part of my project is presence control and I want to generate a qr code that will contain the geographic coordinates of the presence control place.
Then I want to recover the coordinates, by scanning the code, and compare them with the coordinates of the one who scans the code (its geographical position).

#

I was able to write the qr code by inserting the coordinates of the presence control place. I also wrote the code to retrieve the user's contact details. But I still don't see how to make comparisons and approximations to manage this properly.

@distant trout i can't really help you.. i just wanted to say that it looks cool

distant trout Jun 3, 2020, 12:22 AM

#

oh thanks lol :p

empty mantle Jun 3, 2020, 12:47 AM

#

@distant trout , make an Ajax post request to your flask server with userID and perform the delete from the SQL database there. Can't help with the SQL query though sorry

distant trout Jun 3, 2020, 12:47 AM

#

oh okay ill try to do that, thank you @empty mantle

empty mantle Jun 3, 2020, 12:49 AM

#

In flask you will want something like

@app.route('deleteAccount',methods=['POST'])
def delete() :
   id=request.data["ID"]
   # do delete

cold anchor Jun 3, 2020, 12:57 AM

#

make sure you authenticate it! don't want users deleting other users' accounts

Do people have recommended resources for learning about things like WSGI, Gunicorn, etc, basically anything deployment related? I've written Flask sites for personal use but never anything deployed.
(I know some tutorials cover basic setup for hosting, but I'd like to learn more background if possible.)

I refered to this one while I was learning, quite satifactory article

Bringing a Python web application into production is properly is best done with the help of a few friendly applications. Gunicorn is one of them. Let's look at what it does, and how it can make your life easier.

he has bunch of articles on django, you can find the links at the bottom of his page

Sure, what's up?

silent knoll Jun 3, 2020, 9:19 AM

i did a pip install but i am not able to run flask
when i do pip list it shows flask but when i try to run it says command not found

quick cargo Jun 3, 2020, 9:22 AM

#

you dont need todo flask run

#

an alternative is todo

#

if __name__ == "__main__":
  app.run()```

#

which will achieve the same thing if flask isnt in PATH

silent knoll Jun 3, 2020, 9:25 AM

@quick cargo thanks when i added if name == "main":
app.run() at the end of file it worked

I'm close to using my mac to smash my own head in

#

I've been trying to use flask to create a landing page for the last four/five days.

#

the only resources I can find online seem to either be for login pages or to do apps.

#

I'm trying to get information from a form using post

#

and then save it in a sqlalchemy data base is that correct?

silent knoll Jun 3, 2020, 10:36 AM

#

@tranquil steeple django is popular these days

tranquil steeple Jun 3, 2020, 10:37 AM

#

@silent knoll so you'd recommend using django over flask even for a simple email capture landing page.

#

?

silent knoll Jun 3, 2020, 10:39 AM

#

depends; if you can't find any resources then you could use your time to build the app in django rather than flask

verbal obsidian Jun 3, 2020, 12:13 PM

I mean, I'm sure there are tons of flask resources for such a simple task

#

@tranquil steeple Is that all your landing page does? Form -> Save to db?

#

@young grove Do you have any specific question?

young grove Jun 3, 2020, 12:19 PM

how can i join all ManyToMany field's values(name) in Django?

@young grove Okay that's great, any specific question or issue tho?

#

@stiff totem by join you mean associate?

stiff totem Jun 3, 2020, 12:31 PM

@verbal obsidian well, i got these models

class Artist(models.Model):
    name = CICharField(max_length=600, unique=True)

class Track(models.Model):
    artist = models.CharField(...)
    artists = models.ManyToMany(Artist, ...)

verbal obsidian Jun 3, 2020, 12:32 PM

The example here is almost the same as your model

sometimes there is artist value is None so i have to write manager method that gets artist value, if not i have to return artists name joined by space

@verbal obsidian i have to begin but i don’t know how so i ask here help to someone that already made a system like that or something like that

limber spade Jun 3, 2020, 4:10 PM

#

Well, I'm a beginner in programming and I have an idea for a project. But my doubt is whether I should use Python or JS.

#

Basically I want to make a website where a user writes a letter and sends it, without knowing to whom

#

And only one random user receives it

#

and so on

#

Can I do this with Django?

zealous siren Jun 3, 2020, 4:12 PM

#

@sour mulch Django and Flask are popular python options

#

fotea, you can use either JS or Python

fickle fox Jun 3, 2020, 4:12 PM

#

u can do it easilywith flask

zealous siren Jun 3, 2020, 4:12 PM

#

JS is worth learning even if you use Python framework for backend

limber spade Jun 3, 2020, 4:12 PM

#

i tried flask and django and i like django more

fickle fox Jun 3, 2020, 4:13 PM

then do it with djanfo if u are more comfortable with it

limber spade Jun 3, 2020, 4:13 PM

do you wantt o be a web developer?

limber spade Jun 3, 2020, 4:13 PM

i can make the front end with django too, right?

zealous siren Jun 3, 2020, 4:13 PM

#

if so, JS

limber spade Jun 3, 2020, 4:13 PM

#

i guess so

#

so then i should make my project in JS and node.JS

zealous siren Jun 3, 2020, 4:14 PM

that will work

limber spade Jun 3, 2020, 4:15 PM

ok, what tutorials should i follow for getting to learn JS and make a basic website for understanding, before i start with my idea?

Okay, so I'm super new to web development and I want to see if the website I'm going to have to refactor is able to use Django. Right now it uses ASP.NET and I'm unsure what I'm doing, how would I find out if it supports Django?

#

(As a note, Google really isn't helping me and despite my best efforts, I'm really not the brightest in terms of web development.)

zealous siren Jun 3, 2020, 4:33 PM

#

.Net is Microsoft language and does not support Django

#

Microsoft has web frameworks, there is C# server that could probably recommend some

shadow hornet Jun 3, 2020, 4:36 PM

#

you'll have to be patient @limber spade. you can't expect an answer immediately

sour mulch Jun 3, 2020, 4:51 PM

#

Are there any resources to teach me about website domains and frameworks (at a definitive level) you guys would recommend?

zealous siren Jun 3, 2020, 4:52 PM

frameworks are so unique that wikipedia article is about in depth as you need before you go with set of frameworks

sour mulch Jun 3, 2020, 5:09 PM

Right, I'll try to look through it then.

Is there anyone that can explain to me how to pass information from my user through to a function i have created in my flask app?

candid totem Jun 3, 2020, 8:13 PM

#

What do you mean @peak dirge ? Is this information comming from a form ?

peak dirge Jun 3, 2020, 8:14 PM

#

I'm really new to all of this, but essentially it will be connected using AJAX

#

the form will be a match 3 game

#

which when the user clicks, will send the location of the 'gem' they clicked on

candid totem Jun 3, 2020, 8:15 PM

#

gem ?

peak dirge Jun 3, 2020, 8:15 PM

#

like in candycrush

candid totem Jun 3, 2020, 8:15 PM

#

oh I see

#

Well the ajax doesn't matter really. What you want is to look at the request data. Let me show you two examples, one using GET and the other POST request.

#

from flask import Flask, request

app = Flask(__name__)


@app.route('/get', methods='GET')
def using_get():
    data = request.args

    return f'Data: {data}'

@app.route('/post', methods='POST')
def using_post():
    data = request.form

    return f'Data: {data}'

#

This is a really naive example but should help you getting started

peak dirge Jun 3, 2020, 8:35 PM

cheers thanks for the help 😀

This works fine, as long as my current url is a basic one. For example website/faq. But whenever i got a dynamic url like : website/user/tickets/ticket_id
i get an error: website/user/tickets/ticket_id/logout doesnt exist.

@finite shell if you need nothing besides REST APIs, I highly recommend taking a look at FastAPI

native root Jun 4, 2020, 12:16 AM

#

@late gale none of that code you have written implies that already present user objects will have profiles created until they are edited

#

As a result, the object does not exist, error

late gale Jun 4, 2020, 12:34 AM

@native root I was following a tutorial and each user who registers have a profile and i did the same as he did and it didnt give the same error for him but for me

In the comments is the same issue

#

when . you create your initail database it comes with a default admin user

#

whcih crucially never gets a profile created

#

The comments suggest either recreating it or creating a new superuser, but I suggest having a simple check to ensure the profile object exists before attempting to access it

late gale Jun 4, 2020, 12:49 AM

#

but creating a new super user or creating user from the database is impossible because i wont make a profile for each user i just want it to be done programmatically

native root Jun 4, 2020, 12:50 AM

#

@receiver(post_save, sender=User)

#

happens when a user is first created or edited

#

your current admin user was last created or edited before this code existed

#

Therefore it never ran, and therefore there's no profile associated

late gale Jun 4, 2020, 12:52 AM

#

so that only happens when i create a super user

native root Jun 4, 2020, 12:52 AM

#

Only on the very first development one

#

I believe if you restarted your db at the moment it would start working, but that's not a very elegant solution

late gale Jun 4, 2020, 12:53 AM

what about if i want a user who just registered from the registration form to have a profile
