@vagrant adder can I pm you so I don't clutter the channel?

#

I have a few questions if that's ok with you

@vagrant adder I get this error:

[SQL: INSERT INTO todo (content, "isCompleted", user_id) VALUES (?, ?, ?)]
[parameters: ('hello', 0, None)]```

This is my models now:
```class User(UserMixin, db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(15), unique=True)
    email = db.Column(db.String(50), unique=True)
    password = db.Column(db.String(80))
    todo_items = db.relationship('Todo', backref='user', lazy=True)

class Todo(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    content = db.Column(db.String(200))
    isCompleted = db.Column(db.Boolean)
    user_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)```

vagrant adder Sep 29, 2019, 6:54 PM

#

just a sec

hollow glacier Sep 29, 2019, 6:55 PM

#

ofc

vagrant adder Sep 29, 2019, 6:57 PM

#

did you do db.drop_all()

hollow glacier Sep 29, 2019, 6:57 PM

#

yeah

#

The problem is when I'm trying to create a todo item

#

    if form.validate_on_submit():
        new_todo = Todo(content=form.content.data, isCompleted=False)
        db.session.add(new_todo)
        db.session.commit()``` This is the code for adding tasks

vagrant adder Sep 29, 2019, 6:58 PM

#

you gotta provide the author

#

since user_id is not nullable

hollow glacier Sep 29, 2019, 6:59 PM

#

@vagrant adder Oh yeah

#

Do you know if flask_login has a good way to get the users id?

#

Isn't it something like current_user.id?

vagrant adder Sep 29, 2019, 7:03 PM

#

yes

hollow glacier Sep 29, 2019, 7:03 PM

#

@vagrant adder I get this error SyntaxError: positional argument follows keyword argument

#

db.session.add(new_todo)
db.session.commit()```

#

Nvm fixed it

#

I'm just dumb

vagrant adder Sep 29, 2019, 7:08 PM

#

nice

brave otter Sep 29, 2019, 9:52 PM

#

anyone know if it's possible to build Q objects dynamically in Django?

#

for example if I have a list of fields I want to OR together like Q(exchange='blah') | Q(exchange='otherblah'), but exchange is a string in a list?

#

nevermind - got a solution - thanks anyway!

modest garnet Sep 30, 2019, 2:23 AM

Is anyone nice enough to help me out with some django? I'm attempting to add a simple dropdown select menu where I have a list of all the choices already. I'm having issues figuring out how I can put the menu on the page and how to retrieve the data from the field.

marsh canyon Sep 30, 2019, 3:25 AM

#

Maybe model choice field?

modest garnet Sep 30, 2019, 3:32 AM

#

yeah I'm trying to figure out how to use it

#

Anything I see online is either super basic or not what im trying to do

#

what im trying to do is make a dropdown menu, and then have a button that adds that selection into a list on the screen

#

@marsh canyon if you understand what I want to do could you send me a pm?

#

or anyone else

marsh canyon Sep 30, 2019, 3:45 AM

#

Sure, i will look into it a bit, just woke up 😅

#

Drop down menu in html can be done using section

#

Or

#

Lemme do some research

modest garnet Sep 30, 2019, 4:22 AM

thanks, im about to go to bed actually so could you pm me anything you have?

Strange issue, getting __init__() should return None, not 'coroutine' with the following:

class User(Object, UserMixin):

    _name = ''
    _id = ''

    async def __repr__(self):
        """
        Output:
            User('username', 'username@example.com')
        """
        return self.__class__.__name__ + '(\'{0}\', \'{1}\')'.format(
            self.username,
            self.email,
        )

    async def __init__(self, email, password, username, *args, **kwargs):
        self._id = username.casefold()
        # Mandatory
        self.email = email
        self.set_password(password)
        self.username = username
        # Optional
        if 'name' in kwargs:
            self._name = kwargs.pop('name')

    async def set_password(self, password):
        self.pass_hash = bcrypt.generate_password_hash(password)

    async def check_password(self, password):
        return await bcrypt.check_password_hash(self.pass_hash, password)

    @property
    async def id(self):

    @property
    async def name(self):
        return self._name

    @name.setter
    async def set_name(self, value):
        self._name = value

#

Any ideas why I'm getting this?

native root Sep 30, 2019, 12:27 PM

#

You cannot have an async __init__

#

if you want the same kind of behavior, you must implement an async __new__

Alright, cheers buddy

How do I set a default value for a WTForm?

hard moon Sep 30, 2019, 7:20 PM

#

Hello here

#

import os

ENV = os.getenv('GLITCHYWARE_ENV', 'dev')

if ENV == 'dev':
    print('DEV')
    from .dev import *
elif ENV == 'prod':
    print('PROD')
    from .production import *

#

This is the content of an init.py file

#

It's supposed to get an environment variable and execute a file according to it.

#

But both files are executed.

#

Here

📎 Screenshot_from_2019-09-30_19-23-39.png

#

It prints 'PROD' only, so it means that ENV == 'prod' and the first if is skipped, but for some reason it runs the code in dev.py

#

I'm using Wagtail a Django based CMS and deployed it on Heroku for information.

magic blade Sep 30, 2019, 8:20 PM

#

looks kinda like .production imports .dev ?

Hello, guys, how to implement oauth2 with pkce ???

pliant hound Oct 1, 2019, 8:53 AM

#

Hey folks. I want to store product info in a database in my flask project

#

Using sqlite and flask-sqlalchemy, I've got a little Model set up:

class Products(db.Model):
    __tablename__ = 'products'
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String, nullable=False)
    overview = db.Column(db.Text)

    def __repr__(self):
        return f"Products('{self.title}')"

#

So if I wanted to store multiline paragraphs in that field, are there any caveats/best practices I need to know about?

vagrant adder Oct 1, 2019, 9:36 AM

#

@hollow glacier
I'll show you when i get home

#

@pliant hound
Class name put in singular, and remove __tablename__, sqlalchemy does that for you by putting it in singular

pliant hound Oct 1, 2019, 9:38 AM

#

Sorry- what do you mean by put it in singular @vagrant adder ?

vagrant adder Oct 1, 2019, 9:39 AM

#

class Product(db.Model):

pliant hound Oct 1, 2019, 9:39 AM

#

Oh. Right I see

#

But other than that, It should be smooth sailing?

#

I'll be able to store multiline strings in the overview?

vagrant adder Oct 1, 2019, 9:40 AM

#

Yeah

pliant hound Oct 1, 2019, 9:40 AM

#

Wicked. Thanks fella 🙂

vagrant adder Oct 1, 2019, 9:40 AM

#

👌

#

Remove tablename @pliant hound

pliant hound Oct 1, 2019, 9:42 AM

#

Will do

#

A book I'm reading sugested I define tablename because sometimes SQLAlchemy can get confused?

vagrant adder Oct 1, 2019, 9:43 AM

#

Nope

#

Exactly different

#

Sqlalchemy shits itself when users fiddle with tablanames

pliant hound Oct 1, 2019, 9:46 AM

Oh dang. Good to know

#

Thank you

yo what do you guys think about DJango in comparison to ExpressJS?

#

is Django any better

#

honestly trying to get into Django so i can strengthen my python skills, a friend of mine told me a while ago he like Django better because it takes care of so many things for you

rigid laurel Oct 1, 2019, 3:46 PM

#

Express is a poorly documented pain in the arse

#

Assuming you want to do a standard CRUD web app then Django is a pretty good choice IMO

native tide Oct 1, 2019, 4:43 PM

#

@rigid laurel but what’s so good with Django though

rigid laurel Oct 1, 2019, 5:02 PM

#

Well, if you want to do Python web development, you have two options: Flask, or Django

#

Flask is a more lightweight option where you have to pick and choose exactly what you want, whereas Django is opinionated and does a lot of things for you

#

the main difference being that Django has an ORM (Object relational mapper) built in for database stuff where Flask doesn't

vagrant adder Oct 1, 2019, 5:02 PM

#

flask is like race car, you have to add some stuff to it

#

and django is like a lambo

rigid laurel Oct 1, 2019, 5:03 PM

#

But, both options are vastly better than JS

vagrant adder Oct 1, 2019, 5:03 PM

#

you get everything, comfort,speed

#

@native tide take a look at sails.js

native tide Oct 1, 2019, 5:09 PM

#

why what about sailsjs should I know about

#

ima try out django later tho

#

I’m bored of express and JavaScript

marsh canyon Oct 1, 2019, 5:09 PM

#

Js can be an advantage if ur also a front end dev? I maybe wrong

#

Btw can anyone explain what can a front end frame work do?

rigid laurel Oct 1, 2019, 5:10 PM

#

JavaScript is necessary if you want to make a modern front end. But it isn't great for anything beyond basic backend stuff

marsh canyon Oct 1, 2019, 5:11 PM

#

Isn't regular js enough for a modern website? What do these front-end frameworks like react add?

rigid laurel Oct 1, 2019, 5:12 PM

#

A JavaScript framework is a way you can make a responsive application on the web. They generally handle the rendering of the actual HTML on the page rather than just letting the browser make a request, that way you can have the page change without refrsehing

marsh canyon Oct 1, 2019, 5:12 PM

#

So like live searches before I hit the search button?

#

I mean i am typing in the search bar and the results appear as I type

rigid laurel Oct 1, 2019, 5:13 PM

#

Yeah, thats one example

marsh canyon Oct 1, 2019, 5:13 PM

#

Can't that be done in regular js?

rigid laurel Oct 1, 2019, 5:14 PM

#

It can, but when you're doing a million similar asynchronous things then it becomes much easier to offload that work to a framework

native tide Oct 1, 2019, 5:14 PM

#

Yes I know Angular already but I’m bored of node lol

marsh canyon Oct 1, 2019, 5:14 PM

#

Okay, thanks for the info mate @rigid laurel :)

rigid laurel Oct 1, 2019, 5:14 PM

Especially if you end up with complex state that you need to manage

native tide Oct 1, 2019, 5:16 PM

Did you check the docs on the library to see what those errors could be

#

Usually they have it listed

peak thicket Oct 1, 2019, 5:17 PM

#

Sadly not.

native tide Oct 1, 2019, 5:21 PM

#

Does the thing work if you try using it in a basic script file like without flask just the library

peak thicket Oct 1, 2019, 5:22 PM

yes

How to structure a Flask-RESTPlus web service for production builds

In this guide I’ll show you a step by step approach for structuring a Flask RESTPlus web application for testing, development and…

snow willow Oct 2, 2019, 11:41 AM

#

the way i see it is compute the dimensions in django based on request, and respond with the needed dimensions for js canvas

#

and make js render the graphics.

supple loom Oct 2, 2019, 11:41 AM

#

Am i the only one using flask here?

native tide Oct 2, 2019, 11:42 AM

#

so i would need to use js to make it?

snow willow Oct 2, 2019, 11:42 AM

#

for web app yes

rigid laurel Oct 2, 2019, 11:42 AM

#

The only thing Flask or Django can do is render static HTML/CSS

#

the use of them is to load data or logic from a server into that static page

#

but it doesn't change the page after it has been rendered

#

no matter what you will need JS if you want to change the page at all after it has been initially loaded

native tide Oct 2, 2019, 11:43 AM

#

guess il have to learn js then

snow willow Oct 2, 2019, 11:43 AM

#

REST API

rigid laurel Oct 2, 2019, 11:43 AM

#

adding Django or Flask into the mix is pretty pointless

snow willow Oct 2, 2019, 11:43 AM

#

and some form of REST for Django or Flask.
Backend here is not that important

supple loom Oct 2, 2019, 11:43 AM

#

What is a good language to make front end for APIs developed using flask?

rigid laurel Oct 2, 2019, 11:43 AM

#

the REST api adds no value to Hydrovo's problem

#

ReactJS, VueJS are two highly reccomended front end libraries

snow willow Oct 2, 2019, 11:44 AM

#

if you want to store the values??

supple loom Oct 2, 2019, 11:44 AM

#

Cool

rigid laurel Oct 2, 2019, 11:44 AM

#

nowhere has he mentioned that he wants to do that

#

and even if he did want to store the values

snow willow Oct 2, 2019, 11:44 AM

#

you can send them from frontend

rigid laurel Oct 2, 2019, 11:44 AM

#

it makes more sense to write hte javascript first

supple loom Oct 2, 2019, 11:44 AM

#

Can anyone look into my problem?

rigid laurel Oct 2, 2019, 11:45 AM

#

ReactJS, VueJS are two highly reccomended front end libraries

supple loom Oct 2, 2019, 11:45 AM

#

Not that...the link above it

snow willow Oct 2, 2019, 11:45 AM

#

@native tide
JS create app first and then you can decide latter if you need a backend or not

rigid laurel Oct 2, 2019, 11:46 AM

#

what is the actual problem @supple loom?

supple loom Oct 2, 2019, 11:46 AM

#

And i play dota too 😍😍

#

when i run auth_test.py file it raises JSONDecodeError

rigid laurel Oct 2, 2019, 11:47 AM

#

are you just using the code verbatim from the github repository?

supple loom Oct 2, 2019, 11:48 AM

#

Well i did some extra....but i am sure i didn't modified that part and it should work

#

The link doesn't tells to run tests...but since i added i naturally ran to check whether it's working or not

#

There is one more problem i mentioned above

#

The logout endpoint.....login is working fine...
But logout says please provide a valid authentication token

#

Say something

#

Check the link once

rigid laurel Oct 2, 2019, 11:54 AM

#

I'm afraid I'm not willing to install this random repository to see where the problem might be

#

and I can't really help just by looking at this code

supple loom Oct 2, 2019, 11:54 AM

#

Yeah...one needs to run to see what is actually happening

#

And i am sure you will run through the same error

#

I have posted screenshots in the issue section of same github repo

#

The link i send is just an article in which he has taught

mint shuttle Oct 2, 2019, 11:57 AM

#

so i have a django backend and django templates being served with csrf tokens in the POST forms to add models.

but i've made a vue frontend that queries the GET endpoint (only one in my app) and i'd like to add functionality to create records with it as well, but if i try to make a form, i get the error at not having a csrf token or whatever. what's the 'proper' way to do this?

supple loom Oct 2, 2019, 11:57 AM

#

Mention me if anyone checks on mine...thanks

snow willow Oct 2, 2019, 12:04 PM

#

@mint shuttle
On your POST method from VueJS you need to send the CSRF token along with POST data.
I have not done this in a long time but i can search for a proper method in my archive

#

CSRF is in the cookies

mint shuttle Oct 2, 2019, 12:05 PM

#

ok that makes sense, how do i get the csrf token? for my situation should i just disable that protection? (it's just an example thing, i don't have any sort of user authentification, and i just assume that everyone in the world has the same data to keep track of/there's only one person?)

snow willow Oct 2, 2019, 12:06 PM

#

    url : 'YOUR_URL_HERE',
    headers: {'X-CSRFToken': $.cookie('csrftoken')},
    type: 'POST',
    dataType: 'json',
    data: {}

#

if the token is not there you need to create a method to retrieve it from django

#

i do not know how you setup vue to work with django

#

best way to find out is to load the index page and check it with browser developer tools if you have that cookie

mint shuttle Oct 2, 2019, 12:10 PM

#

ok, ty for the info! i think that'll be enough for me to have direction with my searches now (i was just getting a bunch of stuff on what csrf protects against and stuff, not practical stuff)

right now it's not really. i'm just using axios to send http requests

snow willow Oct 2, 2019, 12:13 PM

you are wellcome

Within Flask is it possible to make something happen without editing every single route? So I can add a suspend function to user without adding a statement on all my routes.

Do you know any Rich Text Editors for Django, that can be used for free commercially and dont have to pay for licence?

#

Oh, I found it

#

You can modify, integrate and use the Open Source CKEditor 4 and the Open Source CKEditor 5 in your commercial websites and products for free as long as our source code and your modifications remain open and accessible to others under the same Open Source license terms.

native root Oct 2, 2019, 3:08 PM

#

I have used tinyMCE, and CKEditor 4 and 5

#

MCE is alright and functional. CKEditor is better, in my opinion, but be wary that they have significantly changed things in ckeditor5 so that it no longer supports html source view

elder nebula Oct 2, 2019, 3:10 PM

#

in CKeditor 4, we could write harmful html source code, could that be the problem

#

Well if it goes to customer, he doesn't need html view

native root Oct 2, 2019, 3:12 PM

#

Whether harmful html makes it through your editor onto your templates is a template design problem. My use cases required HTML input, however, so that was not an option

#

Django automatically escapes out html tags, unless you mark it with |safe, which disables auto-escaping

elder nebula Oct 2, 2019, 3:13 PM

#

I didnt use CKeditor for the reason that someone could make alerts, I only used it if it was behind password

#

Yeah

#

Anybody know how to get user input into forms using Sanic? Here is the code I currently have in the main py file;

@app.route('/data', methods=['POST'])
def handle_data(request):
    cid = request.form['cid']
    print('cid')

And here is the html:

<form method="POST">
    <input type="text" name="cid" placeholder="CID" action="/data">
</form>

But whenever I send the user input, the page in my browser then says; Error: Method POST not allowed for URL / & in console I receive the error:

that's an error in your server code somewhere, you haven't shared it so I don't know what's wrong

That specific error I believe is that you are not returning a response from your code, so perhaps that function needs to return an httpresponse

Yes, you need a return response.etc for your post too, since when the browser submits the form it uses the response from the post request as the html to display

something i've never seen in a django project that just came up -- test data is being written to the live (well, dev, so, it's kind of ok?? but still) database.

#

database test_appname is empty, but database appname has a bunch of extra rows with data from factory_boy (using --keepdb to make it easier to inspect what's happening)

#

if i run tests for an app without --keepdb, and connect to test_appname via psql, it cannot delete the test database, but it still has not written anything to the test database.

#

new rows have appeared in the "live" db instead

So when i click on like button, the page refreshs and goes back to starting. I dont know js yet but it will be cool if anyone could give me a code snippet which i could use for not refreshing the page when someone clicks on the like button

So what you want is a button on the webpage that the user clicks that will do something with Django models to say that X post has been liked by Y user?

#

and the button doesn't refresh the page

marsh canyon Oct 4, 2019, 12:31 PM

#

the button is functional and like feature is all working, the only problem is the page refreshs and goes to the top

#

kinda yea, on clicking the button, page should not refresh

#

kinda like a instant update?

rigid laurel Oct 4, 2019, 12:32 PM

#

where is the code that handles the like currently?

#

the view and template for it

marsh canyon Oct 4, 2019, 12:32 PM

#

in posts app

#

there are 2 templates

#

detail-post.html

#

display-posts.html

#

and u can see the view in views.py , should be the last one i believe

#

so depending on the user if he/she has liked the post, i change the icon, like solid thumbs up if likes and outline if not liked

rigid laurel Oct 4, 2019, 12:34 PM

#

I'm not familiar enough with Django - def like_view(request, slug, destination): does that handle a get, post, or any request?

marsh canyon Oct 4, 2019, 12:35 PM

#

get

#

it handles when someone clicks the button, the button is basically <a> tag, which goes to an endpoint handled by like_view which again redirects the user to the same page making it refresh

rigid laurel Oct 4, 2019, 12:38 PM

#

I'm not sure on the correct way to do AJAX with Django is the thing. But from the JavaScript side its relatively simple.

what you want is a new view, or just rewrite like_view that returns a JSON instead of HTML. Then the JavaScript will make the AJAX request, which can be almost as simple as fetch('http://your-domain/like_view');, and make any necessary visual updates to the page

marsh canyon Oct 4, 2019, 12:39 PM

native root Oct 4, 2019, 2:04 PM

#

If Iceman is still looking, or someone else is trying to figure out how to do this

#

You bind an event handler to your "like" link, that sends an ajax request to your server. It may first increase the vote count, or it might wait for a response before increasing it or setting it to the new number (if it has changed server side since then). Jquery has some methods that make this easy, $.ajax(some_things). You generally have an endpoint defined for this, something like yoursite.com/post/like, and you do a POST ajax request from there. On the django side, you hook up the view to the post request, making sure that the post ID and other details you need (like authentication) are in place, which you should have already from setting up the precursors

#

The view would take the post request and handle "liking", and return a reply depending on what you want to do in the javascript (a JSON response with the new number of likes is an option that many use). The javascript then parses the response from the ajax request and updates the button

marsh canyon Oct 4, 2019, 2:28 PM

Hello, is there any way to manage user permissions in DRF?
I have a ModelViewSet of a Task model, and I would like it so only the user associated with the model can DELETE, GET, PUT or PATCH it, while any authenticated user would be able POST on the view.

native root Oct 4, 2019, 3:54 PM

#

Change the a href=url to a data parameter, and using jquery, you'd want the template to look something like this:

<a data-like="{% post.slug %}" ...>

$(document).ready(function(){
    $("[data-like]").click(function(event){
$.getJSON('/like-this-url', { like-item: $(this).attr("data-like") }, function(data) {
    $("span.count", this).text(data['count']);
});
    });
});

#

Then you set up a view at /like-this-url, which takes a GET request with a parameter of like-item, does the "like", and returns a json result that includes an object with "count" equal to the new count

#

I don't actually have the spare time to fully tie it in, but that should be enough to get you where it ought to be workable

#

If you want it to be a post request you can adjust it to use this instead, which should just be a code rearrange:
(shamelessly stolen from stackoverflow https://stackoverflow.com/questions/8951810/how-to-parse-json-data-with-jquery-javascript )

            $('body').append($('<div>', {

#

If you're looking for a more structured approach, you'd end up giving each of your "post"'s their own divs, which would then allow you to operate on them by id, which is the usual and easiest way of going about it

#

$() accepts css selectors, $(this) is the current element (in our case, the one being clicked), and if you do $("selector", this) you search under the current element

#

.text() changes the text

I have another question regarding Django.

#

I have a webpage with a form. Upon submit, it sends form data to the db, and also when pressed, js opens a "thank you" modal window. There's a method that checks submitted form and I'd like to return the result into that modal window, essentially to js so it can print it in that modal window.

How do I approach this task?

I assume I should do it with json, but that's just a guess, so I'm asking here.

Thank you mate

native tide Oct 5, 2019, 3:57 PM

#

Allo

#

So I'm making a flask app

#

and it includes some modules that "do a thing", for instance there is a module that text to speeches a lump of text to an MP3, and there is another module that converts e-books into a bunch of snippets for text to speeching

#

what should I be calling these 'modules that do stuff'. I feel like they should go in a folder in my project structure

#

I was thinking that the folder could be called 'services'

#

but that's probably not right...

#

usually the folders are named after a design pattern. What is a design patterny name for 'classes with a specific responsiblity'

#

I'm feeling like the correct answer might be 'your libaries that do stuff should be in their own repos, so the flask app can just be a flask app, install, import and use them'

native root Oct 5, 2019, 4:04 PM

#

My opnion, services is just fine. Since that is what they are, services provided by your flask app. Separate repos is probably overkill for them--they aren't going to change rapidly, and are probably not big enough to be worth the management hassle

#

There is a balance to be struck between complexity and modularity. One end leads you to massive files, slow processing times, spaghetti code, and unmanageable branching and merging. Too far towards modularity and python begins to look and act like Java-tons and tons of boilerplate, modules that do nothing but import other modules and call singular functions

#

The reality is, if you go too far either way maintainability begins to drop

native tide Oct 5, 2019, 4:08 PM

#

thanks, sometimes it's nice to have permission from the internet to call things stuff

#

I ended up trying to fix a firefox pluggin that was written as one of these... apps with classes implimented as one big file full of functions that do stuff

#

and it's much worse than I remembered

#

by slicing things up, you hopefully end up with really small scopes and not many variables in them. I think this, horrible lump of javascript I was staring at would have seemed normal back in the day, but having got used to "functions only use variables that turn up as parameters, no global variables"

native root Oct 5, 2019, 4:10 PM

#

There is an optimal amount of complexity that ought to be shown on screen and considered at once. You can spread it out via classes, and abstractions, and you can bring it together with long procedural functions with variables

native tide Oct 5, 2019, 4:11 PM

#

turns out a variable that belongs to a class is really just a global if your class is big enough

Does anyone have any idea as to why my flask session variable is being reset in between requests?

I modify it, print it at the end of the request and see the difference, however at the start of the next request it has reverted

#

is there much benefit to using libraries like flask-bootstrap as opposed to just setting up the static imports manually?

vagrant adder Oct 6, 2019, 7:19 PM

#

not really

#

you can shave few miliseconds off loading webpage

lapis stump Oct 6, 2019, 8:00 PM

#

cool

#

because flask-bootstrap does caching as well?

vagrant adder Oct 6, 2019, 8:04 PM

#

yeah

#

i would rather link it on frontend since those miliseconds aren't noticeable

#

and flask-bootstrap just adds complexity on the backend part

raw oxide Oct 6, 2019, 8:05 PM

#

Is there any benefits for using Flask or Django besides Flask is easier to learn?

vagrant adder Oct 6, 2019, 8:07 PM

#

easier on resources(not something you should twist your head for)

#

flask's ease of use is just something django can't beat

#

it's modularity is good too

lapis stump Oct 6, 2019, 8:17 PM

#

if my goal in using flask is to just quickly throw up webui's for some python code I'm running in the background (in other words, personal tooling and not public web facing)

#

any relevant libraries I should take note of?

rigid laurel Oct 6, 2019, 8:22 PM

#

Depending on how usable you want the UI to be, probably a lot of JS stuff you should be aware of like possibly ReactJS or Jquery

How do i serve dynamic files?

mint shuttle Oct 7, 2019, 2:53 AM

#

so i have a table to keep track of a many to many relationship between two other tables, all using django to form the modles.

I have a modelform that lets you make the assignments to populate this table with the proper relationships

but currently it uses a drop down and shows modelobject(n) instead of something like the object's name. but I'm not finding the right search term to have this expose model.name instead of model.id. any ideas?

#

A requirements.txt must be present at the root of your application's repository to deploy.
To specify your python version, you also need a runtime.txt file - unless you are using the default Python runtime version.

#

That's the error message you get when you forget to specify requirements.txt

Use a Procfile, a text file in the root directory of your application, to explicitly declare what command should be executed to start your app.

#

Currently you aren't, so it's not running any applications, and thus you get that error

Hi all

#

I have some weird problem with launching my website. It works fine except it won't update html content after git pull

#

I have restarted the server itself, nginx and gunicorn and checked that files are actually new. And it still shows the old version.

#

Can someone help me find what I 'm missing please?

native root Oct 8, 2019, 2:58 AM

#

If you have not done a full refresh, it's likely the browser is caching the old files

#

On desktops, control-shift-r, or shift-f5, of cmd-shift-r triggers a cache-refreshing reload

#

On mobile, you'll generally have to go into the browser settings and erase the cache

frigid egret Oct 8, 2019, 3:08 AM

#

Refreshing with cache, it became a habit once I got into web development XD

#

Also tried in another browser

Do you have cloudflare between you and the app?

frigid egret Oct 8, 2019, 3:23 AM

nope

native root Oct 8, 2019, 3:23 AM

#

What are the headers you're getting from the server?

#

You can find those in a network tab of some dev tool in the browser

frigid egret Oct 8, 2019, 3:24 AM

Well, I think with that we can probably rule out a user-facing cache

Which means that nginx probably is serving up the old files

the question is why

#

Something up with your nginx.conf, maybe?

How did you restart gunicorn?

#

copy the whole thing?

native root Oct 8, 2019, 3:33 AM

The question is whether the restart of gunicorn failed, which could leave it running the older versipon

That would put errors in the logs if it's configured correctly

probably

You are not capturing the theatre_id, but adding the word theatre_id as the actual route/url:

Wild guess, but you may need to have two different endpoints, one for the top function /<id> and one for the lower function /audit/<id> (or something), since otherwise it can not differentiate.

lofty matrix Oct 8, 2019, 5:04 PM

#

With Django, I frequently have models with FileFields or ImageFields. When the model is deleted, the files are not deleted automatically. This means that for each model, I need to listen for the post_delete signal, and iterate over the files and delete them from the storage backend. This results in a bunch of the same function, but with different fields and listening for different senders, which is easy to forget to update if I change something. Is there a better way to handle this which would attach the logic to the model itself?

lofty matrix Oct 8, 2019, 5:20 PM

https://docs.djangoproject.com/en/2.2/ref/models/fields/#django.db.models.fields.files.FieldFile.delete gives the recommendation of a custom management command to purge orphaned files, but I can't find an example of this

mint shuttle Oct 9, 2019, 2:42 AM

#

with django:
I have a model for items(cyphers) and a model for decks (lists of cyphers) its a many to many relationship.
I have DeckCypher which assigns cypher and deck ids.
I'm trying to write code that will generate a json object where the key is the deck name, and the object is the cypher. I have

data = {}
        for k, v in DeckCypher.objects.all().select_related():
            if k.name not in data.keys():
                data[k] = []
            data[k].append(v)
        json_data = json.dumps(data)
        return Response(json_data)```
but it doesn't know how to unpack model.objects.all().select_related() and I don't know how to perform the join operation later if I wanted to just track the ids for the loop. Any suggestions?

Here has a method of grabbing the ciphers, and attaching them to decks in a manner you could use to process them: https://stackoverflow.com/questions/4823601/get-all-related-many-to-many-objects-from-a-django-queryset

Stack Overflow

Get all related many-to-many objects from a Django QuerySet

I have a twisty maze of interrelated Django models, with many-to-many fields describing the relationships.

What's the cleanest way to get a list of unique members of a related model from a QuerySe...

#

You can get a selection of Decks and all their component cyphers via Decks.objects.prefetch_related('ciphers').all(), with filtering wherever you'd want

#

If you can have duplicates, .distinct() is your friend

How do I add custom fonts to Django ckeditor (Google Fonts ect.)

#

I found it! Here's the code if anyone needs:

CKEDITOR_CONFIGS = {
    
    'default': {


        'toolbar': 'toolbar_Custom',
        'font_names': 'Roboto;',
        'toolbar_Custom': [
            {'name': 'Font', 'items': 'font_names'},

I have a flask app and I have this custom Jinja2 extension ```py
from flask import url_for
from jinja2 import nodes
from jinja2.ext import Extension

class StaticfilesExtension(Extension):
"""
A class that allows serving static files in the format {% static 'file/path' %} over the built-in {{ url_for(...) }} method.
"""

tags = {'static'}

def __init__(self, environment):
    super().__init__(environment)

def parse(self, parser):
    next(parser.stream)  # we have to call this
    filename = parser.parse_expression()

    return nodes.Const(url_for('static', filename=filename.value))


and it works as expected here ```html
    <link rel=stylesheet type=text/css href={% static 'css/reset.css' %}>
    <link rel=stylesheet type=text/css href={% static 'css/style.css' %}>
    <link rel=stylesheet type=text/css href={% static 'fonts/Overpass Mono/overpass-mono.css' %}>```
but when I have this ```py
<source type=audio/mpeg src={% static 'sound.mp3' %} >```
I suddenly get a syntax error ```py

That wouldn’t work in your css, but your css is currently pointing the image at my site.com/images/sailaway, but the image is under your css folder too—site.com/css/images/sailaway

#

Or perhaps /static/css/...

native root Oct 10, 2019, 3:17 AM

#

If that doesn’t help, take a look in the dev tools network tab in your browser, usually gotten to via right clicking an element and “inspect”ing

That will tell you the resources requested and received

#

It is possible your image is so big that “cover” causes it to get lost in unclear colors, but I’m not sure

frigid raft Oct 10, 2019, 5:05 AM

#

I think it is a fairly large image

#

well

#

it is 1920 x1080

#

📎 unknown.png

#

when i hover over it in inspect element, it appears as 100x0 on the right

native root Oct 10, 2019, 5:18 AM

#

x0 means that it's not displaying because the height isn't working

#

This depends on what's inside it, but if you've absolutely positioned the text inside, the container will have 0 height, and not show the background

frigid raft Oct 10, 2019, 5:19 AM

#

Can you review the source code i have above?

#

html {
    /* To make use of full height of page*/
    min-height: 100%;
    margin: 0;
}
body {
    min-height: 100%;
    margin: 0;
}
``` I also have this if this matters

Hey i've got a question about Django Admin

#

I have to create a page to make a new object (Intersticial)

#

but i have to call a special script when the object is created

#

what can i override to do that ?

unborn terrace Oct 11, 2019, 8:03 AM

#

@ripe mango Django signals ?

ripe mango Oct 11, 2019, 8:03 AM

#

Hmm not really

#

the "script when the object is created" is to creating an other object lol

#

so its just one-line

unborn terrace Oct 11, 2019, 8:03 AM

#

Django signals allow that

ripe mango Oct 11, 2019, 8:04 AM

#

yep but why using a signal ?

#

i can simply override the function called at the creation of an object

#

and insert my request to create a new object after the commit

#

so, the real question is: the function hmm

unborn terrace Oct 11, 2019, 8:05 AM

#

@ripe mango signals are functions created at the creation of an object

ripe mango Oct 11, 2019, 8:05 AM

#

   def add_view(self, request, **kwargs):
        super(IntersticialAdminForm, self).add_view(self, request, **kwargs)
        print("Adding new object.")
        print(self.fields['add_subarea'])

#

this is good ?

Oh a form

ripe mango Oct 11, 2019, 8:06 AM

Yepp sry

I thought you were talking about a Model instance

ripe mango Oct 11, 2019, 8:06 AM

#

i have not mentionned that is a form

#

nop, i'm in the form /add/ on the admin panel of django

#

and after that, the object will be create 🙂

unborn terrace Oct 11, 2019, 8:07 AM

#

So you want to add fields to the form right ?

ripe mango Oct 11, 2019, 8:07 AM

#

hmm, i have self.fields that contains a list

#

and for all elements in this list, a new object will be created (in an other model of the form)

#

thats why i need to do that manually

unborn terrace Oct 11, 2019, 8:09 AM

#

What are these “new objects” ?

ripe mango Oct 11, 2019, 8:09 AM

#

The form is set on Intersticial model, and I have to create new objects in GeoExclude model

unborn terrace Oct 11, 2019, 8:09 AM

#

Okay, well in such case you have to work that in the form save method I guess

ripe mango Oct 11, 2019, 8:11 AM

#

oh its save ?

unborn terrace Oct 11, 2019, 8:12 AM

#

Yeah, well to me that's save's responsibility

#

Or a Django signal if you want to generalize the behavior beyond that model's admin interface

ripe mango Oct 11, 2019, 8:13 AM

#

    def save(self, commit=True):
        intersticial_obj = super().save(commit=False)

        if commit:
            intersticial_obj.save()
            for geo_exclude in self.fields['add_subarea']:
                # Creating here my new object
        return intersticial_obj

#

what you mean of that ?

#

(edited)

unborn terrace Oct 11, 2019, 8:14 AM

#

Could you please explain what Intersticial and GeoExclude are, and why do you want to create GeoExcludes objects after Intersticial here ?

ripe mango Oct 11, 2019, 8:14 AM

#

Hmm, ok

#

an Intersticial can have some exclusion

#

like if you want to exclude the France country

#

you can have a lot of exclusion

unborn terrace Oct 11, 2019, 8:15 AM

#

Please don't exclude my country

ripe mango Oct 11, 2019, 8:15 AM

#

je suis français aussi lol

#

ça doit se voir à ma façon d'écrire

unborn terrace Oct 11, 2019, 8:15 AM

#

Les français s'excluent tout seul, c'est vrai 😏

ripe mango Oct 11, 2019, 8:15 AM

#

aha

#

Intersticial model contains all informations relative to the intersticial.

#

GeoExclude model contains all country excluded, with a foreignkey to Intersticial

#

are you sleeping down on your keyboard ? 😂 @unborn terrace

unborn terrace Oct 11, 2019, 8:22 AM

#

@ripe mango I was typing a long “solution” but I just remembered something

#

Why not using inline forms ?

#

Well, inline admins*

#

hm what is ?

unborn terrace Oct 11, 2019, 8:23 AM

#

https://docs.djangoproject.com/en/2.2/ref/contrib/admin/#django.contrib.admin.InlineModelAdmin

ripe mango Oct 11, 2019, 8:24 AM

#

it sound really better lol

unborn terrace Oct 11, 2019, 8:24 AM

“to edit” is in the sense of “that you'll be able to change in the form as any other form”

#

Yeah, that's the “standard” one tbh

ripe mango Oct 11, 2019, 8:25 AM

#

i will try first the method with save override

unborn terrace Oct 11, 2019, 8:25 AM

For VSCode what plugins do you recommend?

open forum Oct 13, 2019, 5:20 PM

#

There are popular plugins for all the major languages you're gonna be using, like Python, JS, TS, CSS, etc.

#

It's easy to find in the extension browser, just make sure to use the ones with a lot of downloads.

Hey. I have a question if anyone uses gitlab. idk why but everytime someone wants to visit my website (even I once) has to login to gitlab first. Is it needed? Or it's cuz it's private repo?

What is the best Python framework for a beginner? I was looking at Django but Flask seems to do what I need.

is jquery installed?

#

or linked

fathom sapphire Oct 14, 2019, 12:49 AM

#

i dont know how to do that id be assuming no

safe garden Oct 14, 2019, 12:49 AM

#

look up a cdn for jquery

#

and copy-paste the script tag it gives you

fathom sapphire Oct 14, 2019, 12:50 AM

#

i thought i just had to code it? is it similar to using pandas in python that u have to call it

safe garden Oct 14, 2019, 12:50 AM

#

no; jquery is a library

#

you need the library linked to be able to use it

fathom sapphire Oct 14, 2019, 12:50 AM

#

ah

safe garden Oct 14, 2019, 12:50 AM

it's like using a module in python without importing it

fathom sapphire Oct 14, 2019, 12:50 AM

#

i shall look into that 👍

#

ok 🙂 i used it and now the consol has no issues

#

but my button doesnt work :>

#

#

thats what i used

but i think the button not working is my fault

@dawn drift
I would say flask because django has difficult to understand view routing and mapping

#

I started with flask and now i'm experimenting with quart

gleaming herald Oct 14, 2019, 5:32 AM

#

@vagrant adder

#

Instead of quart try fastapi

#

It's way better

I'm using django and some of my CSS that are in the same file dont work and some of them do

#

they work in development

#

but theyre not working in deployment

native root Oct 14, 2019, 5:41 AM

#

Define 'don't work'. Have you checked to see if they're being requested?

frigid raft Oct 14, 2019, 5:42 AM

#

wdym requested? When I look at my sources through inspect/chrome dev console the classes are there

#

Here is an example

#

vagrant adder Oct 14, 2019, 5:43 AM

#

@gleaming herald what's that

native root Oct 14, 2019, 5:43 AM

#

That's good enough. The dev console includes a "network" tab, that lets you see if the files are being requested by your page and handed back by the web server

frigid raft Oct 14, 2019, 5:43 AM

#

📎 unknown.png

#

THe first one is on deployment

#

2nd is on development

native root Oct 14, 2019, 5:43 AM

#

Hm

frigid raft Oct 14, 2019, 5:43 AM

#

The other css in the site works

#

which is in the same file

native root Oct 14, 2019, 5:44 AM

#

And the new css visible in development is being loaded by your browser, and not applied to the page?

frigid raft Oct 14, 2019, 5:44 AM

#

wait actually let me correct myself

#

the classes dont appear in the dev console

#

sorry i thought it did

#

they ARE in the file though

native root Oct 14, 2019, 5:45 AM

#

Ok

#

Did you try a cacheless reload?

#

Ctrl-shift-reload?

frigid raft Oct 14, 2019, 5:45 AM

#

yeah i tried that

#

i tried a dif browser as well

native root Oct 14, 2019, 5:45 AM

#

Hm

#

How are you deploying?

frigid raft Oct 14, 2019, 5:46 AM

#

apache2 on a VPS

#

i tried restarting apache2 as well

native root Oct 14, 2019, 5:46 AM

#

Also, if you go to the network tab, you can view the raw file being served by your live environment. Is that file different than what you've got on disk?

frigid raft Oct 14, 2019, 5:46 AM

#

and i did collectstaic

#

let me check

#

it is the same file

#

with the missing classes though

native root Oct 14, 2019, 5:47 AM

#

Ok

#

So what we've established is that the live server is giving out old copies of your css

#

Next step is to check the files on disk in the live environment, to see if they're up to date

frigid raft Oct 14, 2019, 5:48 AM

#

It is up to date on my VPS

native root Oct 14, 2019, 5:49 AM

#

And in the collectstatic folder on the vps it is up to date?

frigid raft Oct 14, 2019, 5:50 AM

#

my css dir is in my staticfiles dir

#

which i use manage.py collectstatic

#

So yes? If that is what you're asking

native root Oct 14, 2019, 5:51 AM

#

yes

#

Ok

#

Well, that means apache is serving the old response, or if you've got cloudflare or similar? That would also be serving that old response

frigid raft Oct 14, 2019, 5:52 AM

#

Wait i found a stackoverflow solution saying to clear static files first so im going to try that

#

1 sec

#

Okay that worked

#

Thanks for being here though!

native root Oct 14, 2019, 5:53 AM

👍

gleaming herald Oct 14, 2019, 7:36 AM

#

@vagrant adder Actually the performance and documentation of fastapi is better

#

if you just are good enough in flask

#

and looking for a change

#

I guess you should try fastapi instead of quart

#

its also async api

vagrant adder Oct 14, 2019, 7:42 AM

#

The thing with quart is that it is compatible with almost all flask extensions

#

Because it's built on top of flask

#

And that's what got me intrigued

#

Also, async ability is just nice

native tide Oct 14, 2019, 10:28 PM

Hello, if anyone uses django-rest, do you prefer django rest token auth, django rest knox auth or django rest jwt ?

gleaming herald Oct 15, 2019, 5:12 AM

#

Oh Okay ! @vagrant adder

vagrant adder Oct 15, 2019, 5:22 AM

#

@gleaming herald so i can build quart app but i can incorporate flask-sqlalchemy

gleaming herald Oct 15, 2019, 5:29 AM

#

Yeah

#

That sounds like a good start

#

I thought if you are learning async backend

#

FASTAPI would be a good place to start

#

It has way more functionality

vagrant adder Oct 15, 2019, 5:34 AM

#

Does it?

#

Hmm

gleaming herald Oct 15, 2019, 5:38 AM

#

Yeah

#

📎 unknown.png

#

the if statement runs perfectly fine

#

but for some reason the while statment doesnt seem to be

#

even though they are both meant to run

#

if it helps the same code that the while is running

#

📎 unknown.png

#

controlled by a different part

#

works fine

#

im just not sure, its just that the while statement lets me iterate instead of click im just not sure what might be incorrect

native root Oct 15, 2019, 11:04 AM

#

@fathom sapphire

#

You're returning inside the loop, is that intended?

#

That will end the loop

fathom sapphire Oct 15, 2019, 11:07 AM

#

oh, 😅

#

even still it doesnt seem to return

#

i have one table

#

which is what it adds a row to basically by cloning it

#

it doesnt add any extra rows

#

how would i get it to call the function without it being a return?

#

📎 unknown.png

#

that's the table

#

and when i add a row

📎 unknown.png

#

but i dont want the button

#

i want it to take from the value and loop till it gets to the number of times

#

since that how many people there are

native root Oct 15, 2019, 11:21 AM

#

just leave the function in the line

#

if (table_body) {
    add_row(table_body)
}

fathom sapphire Oct 15, 2019, 11:21 AM

📎 unknown.png

native root Oct 15, 2019, 11:22 AM

#

yep

#

I'd also suggest indenting that } the line after, it's misleading as it appears now

fathom sapphire Oct 15, 2019, 11:22 AM

#

that's what i ended up doing but it unfortunately still doesn't run

#

😄 I'm thankful for the help so far though

hopefully you can see what I cannot unless its something bigger than that
