change it to 50%

native tide Mar 28, 2020, 8:36 AM

#

flex: 1 1 var(--pixels)px; are those good defaults to start with? Not sure I understand what the first two are affecting yet. I know its grow and shring.

btw is that legal css with the var() .. I noticed that it works sometimes when I do it and not always

tired root Mar 28, 2020, 8:37 AM

#

I never use var tbh

native tide Mar 28, 2020, 8:37 AM

#

ah, I love them

#

for color values and numbers i use a lot.

#

This is exactly what I need to make my damned thing i was making earlier.

#

I was resorting to just... stuffing classes and properties to make things match.

#

Then media querying when they dont work at a size

#

Like this is still not lined up the way it should be haha. But its fine for now.

#

I settled for "forgot" because everthing longer than that took up too two lines of space for some reason

#

I'll probably move it down below later. tired of fiddling with it.

tired root Mar 28, 2020, 8:44 AM

#

put it as a link below the login button, spanning the width of the form

#

does not have to be a button

native tide Mar 28, 2020, 8:48 AM

#

yeah, that's how it originally was. I was just playing with different things earlier with it. I learned some stuff but I also learned that I need to learn some more stuff. I put those things in at least 6 different arrangements trying out bootstrap classes in various combinations. ha. It ended up being the simpler approach was better.

#

I got a random question. How would you approach this. This is a screen cap of me zoomed out in my browser to demonstrate the experience of people with the modern absurdly large resolutions of today.

How would you go about checking that the size of the screen is pushing the top menu too far to the left and then push it back the other way so that its more aligned with the header?

Or do you think its fine like that? I dont use that large of a res anyway but people do.

#

It has something to do with a position setting and coordinates im sure

#

Also my colums are not spaced equally because I am fixing them ha

tired root Mar 28, 2020, 8:54 AM

#

I am trying out flask-socketio

#

i don't get it

native tide Mar 28, 2020, 8:54 AM

#

is it like normal socket on flask?

tired root Mar 28, 2020, 8:55 AM

#

It's weird for sure

#

It says: The application must serve a page to the client that loads the Socket.IO library and establishes a connection:

#

But it does not load my template

#

so there is no connection being made

#

from flask import Flask, render_template
from flask_socketio import SocketIO

app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
socketio = SocketIO(app)


@app.route("/")
def index():
    return render_template("index.html")


if __name__ == '__main__':
    socketio.run(app)

native tide Mar 28, 2020, 8:56 AM

#

the only thing ive really ever done with sockets is open them, listen on ports for transmission, and receve them from another script haha. Good luck

#

how do i stop elements from overlapping eachother when i shrink my browser?

tired root Mar 28, 2020, 9:11 AM

#

give me a fiddle with the problem @native tide

native tide Mar 28, 2020, 9:11 AM

what? @tired root

tired root Mar 28, 2020, 9:12 AM

#

a minimal example using jsfiddle

native tide Mar 28, 2020, 9:12 AM

#

flex, grids, media queries, and possibly by using bootstraps col system if you cant figure those out.

But yeah. That.

#

what do i do with the fiddle?

tired root Mar 28, 2020, 9:14 AM

#

You make a minimal example that illustrates your issue

#

css and html are way too complex to give you an answer based on your previous question

native tide Mar 28, 2020, 9:14 AM

#

oh ok

#

sorry, pretty new to this

#

yeah, you just copy your html yo html part, the css to the css part

#

and then click save

#

you get a url and show it to use

#

can't i jiust send my html and css here

#

Then someone would just be having to make fiddles for you. Might as well learn to do it.

#

sorry

#

its all good

#

its like pastebin

#

cool

#

Im gonna take the time to master this flex and grid stuff before I sink away a lot of time just tinkering with what css I know. There are too many conditions for things to go wrong to not approach it with perfect best practice i think

#

im tired of the one little thing that i cant figure why it does that.

#

So im learning this stuff.

#

It seems more robust than cramming properties everywhere.

#

@tired root any luck?

tired root Mar 28, 2020, 9:28 AM

#

about what?

#

If you mean the fiddle, I don't see anything overlapping there

native tide Mar 28, 2020, 9:32 AM

#

if you resize, his content is covering up his bio link

tired root Mar 28, 2020, 9:33 AM

#

resize which way?

#

The document is also missing the opening <html> tag

native tide Mar 28, 2020, 9:34 AM

But its maybe going to get you started ...

#

i put that html tag iin there for you

tired root Mar 28, 2020, 9:36 AM

The whole css is also only using static sizes

Which is bad when you deal with different screens

Hi, I'm the django beginner. I want to know how to let the pdf file show on the webpage. I have a index.html that can show the content: title, abstract, year and others so far. And I've made the title became clickable to another web address. But how can I create a new page for this address and showing the pdf content? Thanks
PS. I have a sql table storing the pdf file path.

tired root Mar 28, 2020, 9:36 AM

heady ore Mar 28, 2020, 9:37 AM

#

is there anyway that is wasy to do that? I dont have any experience in front end

#

so it might be a huge gap

tired root Mar 28, 2020, 9:38 AM

#

That is the easy way

heady ore Mar 28, 2020, 9:39 AM

#

so I think the first step for me is: create a page that shows the file_path after I click the title

#

but actually I dont really know how to start

tired root Mar 28, 2020, 9:39 AM

#

Showing the file path on the server isn't a very good idea

#

The question is, what you want to do here

#

if you want to display a pdf in your web page, use pdf.js

heady ore Mar 28, 2020, 9:40 AM

#

i know. but at least it allows me to link two sql table

#

i dont know how to do this yet

tired root Mar 28, 2020, 9:41 AM

#

This does not make any sense

native tide Mar 28, 2020, 9:41 AM

#

I should learn transition

#

the css prop

tired root Mar 28, 2020, 9:41 AM

#

How does displaying a pdf make you "link two sql tables"?

heady ore Mar 28, 2020, 9:42 AM

#

i have two tables. one has the info of doi, title, abstract and others. another has doi and file path, the doi is the foreign key

#

so now i only able to show the content from the first table

#

and want to know how to link to another based on doi

tired root Mar 28, 2020, 9:44 AM

#

Use a sql select with a where statement

#

SELECT doi, file_path FROM tablename WHERE doi=?

heady ore Mar 28, 2020, 9:44 AM

#

i know how to do that in sql command, but how can i implement that in django?

tired root Mar 28, 2020, 9:44 AM

#

or use a inner join on the first query

#

what are you using as a database connector?

native tide Mar 28, 2020, 9:45 AM

#

https://docs.djangoproject.com/en/3.0/topics/db/ if you havent read this pretty thoroughly, it will help you deal with databases thru django

Models and databases | Django documentation | Django

heady ore Mar 28, 2020, 9:46 AM

#

I use postgresql

native tide Mar 28, 2020, 9:48 AM

#

the models system is the most useful thing about django, there is an entire ORM for interacting with a database. You run queries through python after setting up your models and then merging to your database. Then you can use those queries in logic (usually under views.py) where you can send context (variables from the logic) to the template to render however you wish.

#

not sure if django is the part that you are struggling with or if front end.

heady ore Mar 28, 2020, 9:50 AM

#

actually, both. I know how to get data from api, sql, mongo, selenium. but haven't known deeply in django.

native tide Mar 28, 2020, 9:51 AM

#

yeah... i had to construct the polls app (documentation tutorial) and then make corey scahfers django class blog project before it really started to click. It is so big that its overwhelming. But it just takes reading and then doing.

#

It is very different from anything i had done before as well.

#

And tbh

#

I still dont know all the intricate details of django. I know the basics.

#

There is too much to know, you basically have to work with it for a long time to be very versed with it

#

basics are not too bad though you just need to read the docs

#

if the HTML is the hard part for you... might want to do that as well. Templating engine isnt very powerful without it

heady ore Mar 28, 2020, 9:57 AM

#

too many things to know to build with django

native tide Mar 28, 2020, 9:58 AM

#

I would say web dev is generally like that I think no matter what you get into it. And probably all dev really in a way.

#

sigh

#

css is some hacky bullshit sometimes. Ive probably been doing it for too long. need break

heady ore Mar 28, 2020, 10:02 AM

#

should i put the sql command in views.py?

tired root Mar 28, 2020, 10:09 AM

#

what do you mean with host?

#

as in, create a new vhost in apache?

#

I mean which address the website is running under isn't really the job of the framework

#

You need to elaborate on what you want

#

What are you using for publishing?

#

As in, server software

#

nginx, uwsgi, apache etc

#

Generally, a subdomain is the servername in the software you use and the sub domain also needs to be announced via the dns

How would I handle a Cyrillic string in Flask's flashed message?
It's complaining whenever I flash() a Cyrillic string

tired root Mar 28, 2020, 10:13 AM

#

Yes, that is the A record

#

the IPV4 forward zone

#

Other records in DNS are ptr reverse zone and AAAA for IPV6

#

at the very least, you should have an IPV4 forward zone and a reverse zone

#

You need mod_wsgi for apache

#

yes

#

Which OS?

#

Debian derivative?

#

okay, that makes things simpler

#

go to /etc/apache2/sites-available

#

touch projectname.conf replace projectname with whatever

#

nano projectname.conf

#

or vi, I don't care

#

are you using tls?

#

lets'encrypt?

native tide Mar 28, 2020, 10:19 AM

#

I dont have my test server encrypted but i also dont have a domain name... and its not open to the web. There is a thing called self signing but I dont really understand what the point of that is

tired root Mar 28, 2020, 10:19 AM

#

It means there is already something running on port 80

#

Is there a nginx or so running?

#

yeah, well then you can't run a second webserver

#

You need to configure this with nginx

native tide Mar 28, 2020, 10:20 AM

#

you can just stop nginx tho cant you?

#

i guess not if youre using it

tired root Mar 28, 2020, 10:20 AM

#

Yeah, the question is if he is using it or not

#

as a mail frontend?

native tide Mar 28, 2020, 10:21 AM

#

cant you serve on another port?

#

or listen on

tired root Mar 28, 2020, 10:22 AM

#

nginx is running as a service dude

#

systemctl status nginx

#

ok, then lets setup django on nginx

#

since it runs on a subdomain, the mail can stay on :80

#

What do you want to use to run django? We can use apache and nginx as a reverse proxy or something like uwsgi and nginx as reverse proxy

#

either way, we need a middle man

native tide Mar 28, 2020, 10:24 AM

#

i would nmap 127.0.0.1 on slightly unrelated not to see what you got open. Is it normal to run a mail server on port 80?

tired root Mar 28, 2020, 10:24 AM

#

It's the web frontend

native tide Mar 28, 2020, 10:24 AM

#

ahh

tired root Mar 28, 2020, 10:24 AM

#

no mail server runs on 80

native tide Mar 28, 2020, 10:25 AM

#

yeah

tired root Mar 28, 2020, 10:26 AM

#

https://uwsgi-docs.readthedocs.io/en/latest/Systemd.html

#

REmove apache, then use uwsgi and serve it on 127.0.0.1 and an arbitrary port above 1023

#

Then configure nginx to act as a reverse proxy

#

Which means, it fetches the pages from 127.1 from the uwsgi server and serves it to the user

#

I gave you the docs for uwsgi

#

I can't do it for you and I can't guide you step by step

#

you need to learn this stuff

#

HOw are you going to maintain it otherwise?

native tide Mar 28, 2020, 10:36 AM

#

getting postgres up on a test server was the hardest thing i ever did i think. Its not that it was that hard really. Its that the things i didnt know prevented me from understanding what i needed to do. I finally figured that out though. I would love to be able to have one of my servers be actually online. But the only way i could do that would be dynamic dns and port forwarding and locking down my router and i just dont think im ready ha.

#

btw I just nmaped my localhost ip and then nmapped my specific local 192.168.x.x ip

#

What is the explanation for the variation going on with the open ports.

#

It was not what i expected and scared me at first but the not 127.0.0.1 address gave back what i expected to see

tired root Mar 28, 2020, 12:45 PM

#

what variation?

#

@native tide

native tide Mar 28, 2020, 2:01 PM

#

@tired root port 631 CUPS 2.2, port 3306 MySQL 5.7.29 1 service unrecognized despite returning data. If you know the service/version,

If I run the same command nmap -sV <ip> on my local ip, its nothing except what I expect to be there. But if I run it on localhost, there is stuff I dont know what that is (the stuff I named).

#

the fingerprint it cant identify seems to be my postgres server's open port.

#

To my knowledge im not running mysql on anything...

#

I might have um... I might have mysql workbench that i never use but tried out one time. Lets see. But still, why does it show on localhost and not literal ip...

its inside a for statement

huh, you can't do += in flask? Odd

native tide Mar 28, 2020, 3:59 PM

#

ikr

quasi ridge Mar 28, 2020, 3:59 PM

#

well lbcount = lbcount + 1 might work

#

iirc those templating systems are separate languages that just happen to resemble python

#

but differ from it in surprising and annoying ways

quasi ridge Mar 28, 2020, 4:01 PM

maybe you can't do assignments inside a template? That'd be ... odd

native tide Mar 28, 2020, 4:06 PM

#

damn

#

i just ended up doing loop.index

#

>>> u = UserAccount.query.first()
>>> u.email
'asdf@asef.com'
>>> u.email = "asdf@google.com"
>>> db.session.commit()

Is this all it takes to update the database?

#

Flask, SQLAlc

quasi ridge Mar 28, 2020, 4:21 PM

#

@native tide Yeah afaict you can't do assignments like in python

native tide Mar 28, 2020, 4:25 PM

Yea i dont like how you cant do alot of python related things in jinja templates

#

i had to define len() lmao

#

i was like wtf i thought that would atleast work

quasi ridge Mar 28, 2020, 4:26 PM

#

there's another template language called "moustache" that I like (in theory; I've never really used it) because it doesn't even pretend to be a python-like language

#

the names make it hard for me to tell what theyu are for

shadow hornet Mar 28, 2020, 5:19 PM

#

yeah the names make them sound scarier than they are

#

a declarative system basically allows sqlalchemy to map classes to database tables

native tide Mar 28, 2020, 5:21 PM

#

Does it not already do that? I was just reading about that one.

shadow hornet Mar 28, 2020, 5:22 PM

#

it does that if you use the feature

#

you import the declarative base and create models with it

#

if you do that, then yes

native tide Mar 28, 2020, 5:24 PM

#

What I mean is I have a models.py file with classes that become tables as far as I know. The only thing I use to make my models is db.Model, UserMixin, essentially db = SQLAlchemy(app)

#

the mixin comes from flask_login

#

But

#

I did just try to add a property to a class that the database did not have

#

and it did not like that

shadow hornet Mar 28, 2020, 5:25 PM

#

add?

#

you can't do that

native tide Mar 28, 2020, 5:25 PM

shadow hornet Mar 28, 2020, 5:25 PM

yeah the database schema is set in stone

native tide Mar 28, 2020, 5:26 PM

#

but does it not have ways to do that?

#

to migrate?

shadow hornet Mar 28, 2020, 5:26 PM

#

if you change it, you have to do migrations

native tide Mar 28, 2020, 5:26 PM

#

in django its easy to migrate

shadow hornet Mar 28, 2020, 5:26 PM

#

because it's all built in haha

#

yeah django is like an all-in-one package

native tide Mar 28, 2020, 5:26 PM

#

yeah, ive looked at those migrations py files

#

so

#

what is the manual process of migrating?

#

#databases or here? they might know a lot about that huh? but maybe not webdev orms

shadow hornet Mar 28, 2020, 5:29 PM

#

i'm not sure about flask-sqalchemy, but for sqlalchemy, you'd typically use alembic

native tide Mar 28, 2020, 5:29 PM

#

ive heard that from someone. Is migrating a task that is worrisome and liable corrupt data you care about?

#

i know that ideally you plan to not need to do that.

shadow hornet Mar 28, 2020, 5:33 PM

#

yeah you typically don't want to do migrations too much, but it should not be too worrisome to do one

#

some practice on some dummy data and you should be fine

native tide Mar 28, 2020, 5:35 PM

#

mm. I'm just not sure what the process entails. I suppose when I really wantto do it I will read up. Right now Im more interested in learning fundamental design done right from the beginning

#

I think im going to stop using sqlite and turn on my postgres server and see how much more difficult it is to work with it. Ive already done it with django. not sure how difficult it will be with this.

quasi ridge Mar 28, 2020, 5:39 PM

well what I did -- certainly not the only way -- was I got an El Cheapo EC2 instance from Amazon AWS

#

got a static IP address (free, surprisingly); pointed the domain name at that address, installed nginx, figured out how to get that working, &c &c

#

result: => https://teensy.info

#

Oh I think I only needed nginx because of SSL -- if you don't mind not using SSL, you don't necessarily need it

but you really should use SSL

oblique hemlock Mar 28, 2020, 5:41 PM

oblique hemlock Mar 28, 2020, 5:41 PM

#

I just want to know how to connect my flask to it

quasi ridge Mar 28, 2020, 5:41 PM

#

so really you could run your flask app right now and it'd probably work

#

well what's the server?

#

apache? nginx?

#

in either case, they should have docs explaining how to use it as a reverse proxy.

oblique hemlock Mar 28, 2020, 5:42 PM

#

Should I type specific thing in app.run?

quasi ridge Mar 28, 2020, 5:42 PM

#

Or you could just shut that down, and run your flask app to listen on the same port (probably either port 80 or 443)

#

I have no idea

#

oh

#

maybe the port number

oblique hemlock Mar 28, 2020, 5:43 PM

#

5000?

quasi ridge Mar 28, 2020, 5:43 PM

#

up to you

oblique hemlock Mar 28, 2020, 5:43 PM

#

So It's okay then

quasi ridge Mar 28, 2020, 5:43 PM

#

if you use 5000, chances are your flask app can peacefully co-exist with your existing server

oblique hemlock Mar 28, 2020, 5:43 PM

#

I tried www.example.com:5000

#

That didn't actually work

quasi ridge Mar 28, 2020, 5:43 PM

#

you might need to do something special to allow incoming requests on that port -- in ec2, for example, you have to add an entry to your "security group"

oblique hemlock Mar 28, 2020, 5:44 PM

#

Oh

quasi ridge Mar 28, 2020, 5:44 PM

#

probably depends greatly on your hosting service

oblique hemlock Mar 28, 2020, 5:44 PM

quasi ridge Mar 28, 2020, 5:44 PM

I doubt that's your hosting service; that's probably just the linux distro you're using

well vultr might have something similar, where you have to explicily tell it "please allow incoming TCP/IP traffic on port 5000"

when you tried www.example.com:5000, did you browser say "connection refused"?

close enough I think

oblique hemlock Mar 28, 2020, 5:48 PM

Yup

quasi ridge Mar 28, 2020, 5:49 PM

#

so either

shut down apache, and have flask listen on port 80, since we know that works already; or
tell vultr to open up port 5000

hint: if you do the first thing, you'll have to run your flask app as root, which sucks

oblique hemlock Mar 28, 2020, 5:50 PM

All ports are opened

how are you accessing your flask site?

quasi ridge Mar 28, 2020, 6:02 PM

serving https is a lot harder than http

brave mantle Mar 28, 2020, 6:03 PM

#

you almost never want Flask to serve HTTPS

#

that's not Flask's job

#

you don't need it at all unless you're in production - in which case, you should be using nginx to service your users (nginx will handle https), plus a worker manager like gunicorn

quasi ridge Mar 28, 2020, 6:05 PM

I think you could put nginx in front of flask safely. I think.

oblique hemlock Mar 28, 2020, 6:07 PM

Any useful documents?

#

I would appreciate that

brave mantle Mar 28, 2020, 6:08 PM

#

You can

#

But generally, Flask won't be able to handle more than one user at a time

#

Even though each transaction will probably take milliseconds

#

when you have a bunch of people accessing your site at once, you'll probably need workers to keep things fast

quasi ridge Mar 28, 2020, 6:11 PM

that I can believe

I personally would put up with that, for the sake of simplicity; I'd switch to e.g. gunicorn only if it was clearly necessary

i learned to do that recently.

with django first but same idea

#

Thanks!

native tide Mar 28, 2020, 6:20 PM

#

its a bit of a learning curve the first time i admit.

#

ther sysadmin that is

#

with the sysadmin stuff, when you get an error that is like, "Yo, the server said nah" which is like a 502 or something like that, you'll want to learn quickly to check logs. Things will work in development that wont work in production server. you have to get used to restarting gunicorn and editing various files in very specific ways. Small things like having a file in a directory that shouldnt be there will cause it bork and not tell you why (directly).

#

But in the logs is the answers usually

#

the web server config was not as hard for me as the database auth permission granting and denying.

#

but i got it eventually

#

Servers dont give obvious error messages. they hide them in files

#

how do you write a postgres url to a remote server's database that requires auth? I typically do psql -U postgres -h 192.168.123.456 -p 5432 -d the_database -W but for Flask I need something like postgresql://postgres@192.168.123.456:5432 ..but i also need to put a password and a database name to connect to somewhere in that url string right?

brave mantle Mar 28, 2020, 6:43 PM

#

postgresql://user:password@host/database

native tide Mar 28, 2020, 6:43 PM

#

wow. cool ty

#

i suppose that is best put into an environmentt variable then.

brave mantle Mar 28, 2020, 6:46 PM

#

Generally, yeah

native tide Mar 28, 2020, 6:49 PM

I uploaded my secret key to my first django test project's repo 😛

#

not that it mattered but thats how i learned

Note: Flask-Migrate makes use of Flasks new CLI tool. However, this article uses the interface provided by Flask-Script, which was used before by Flask-Migrate. In order to use it, you need to install it via:

Would you skip Flask-Script and just use whatever new CLI tool... I'm learning Alembic and migrations with Flask-Migrate.

class Result(db.Model):
    __tablename__ = 'results'

    id = db.Column(db.Integer, primary_key=True)
    url = db.Column(db.String())
    result_all = db.Column(JSON)
    result_no_stop_words = db.Column(JSON)

    def __init__(self, url, result_all, result_no_stop_words):

        self.result_no_stop_words = result_no_stop_words

    def __repr__(self):
        return '<id {}>'.format(self.id)

I see some people frequently skip the traditional __init__ method for setting attributes when they write Flask-SQLA models. I'm not sure why or why not. The properties are eventually accessible through q = Result.query.first() and then q.prop -- but is the difference that those values are from the DB and not attached to the instance at all? The syntax is otherwise the same for calling a prop from the db as from the instance. It doesnt cause any problems to do both does it?

        super(UserAccount, self).__init__(**kwargs)

        # Initialize Attributes
        self.id = id
        self.email = email

I would argue, however, that the super call should set all of them by default so they're probably superflous

native tide Mar 28, 2020, 8:00 PM

#

thants what it was thinking but not sure. I barely understand that super() thing to tbh. I know what it dose sort of but the syntax is confusing to me.

#

I put it there because it worked

#

it has variations that are more than just super().__init__()

#

I prefer not to have it in this code, it does seem extra.

queen bough Mar 28, 2020, 8:07 PM

#

@native tide super isn't extra - there's a reason it's necessary. Your class's __init__ is overriding the parent classes __init__s. To ensure that all the __init__s are called, you use super.
https://www.programiz.com/python-programming/methods/built-in/super
https://realpython.com/python-super/

native tide Mar 28, 2020, 8:08 PM

#

oh no, I get that part. I mean extra as in all the property saving that isnt necessary apparently. I get why you have to inherit the base classes traits. What confuses me is when the syntax looks like this

#

    def __init__(self, **kwargs):
        super(UserAccount, self).__init__(**kwargs)

#

what are those positional args?

queen bough Mar 28, 2020, 8:09 PM

#

Print them and see!

#

Oh you mean what **kwargs do - https://book.pythontips.com/en/latest/args_and_kwargs.html? Also, to print them simply use print(kwargs)

#

Not sure what the purpose is in this context.

native tide Mar 28, 2020, 8:22 PM

#

Oh, I know what keyargs do. Its the clarification of super(ClassName, self) that i dont get. Ive always seen it called with no arguments.

And to be honest, I dont know why Im using it here. I know why you typically want to inherit traits from a base class, but in this case, I literally just put it here because thats what Corey Shafer did when he wrote his user class and he didnt explain why. In fact he didnt add it at all until he discovered there was some error on a production server.

#

if i recall

I still dont even know what a Mixin is haha, i just use it.

Ill get to that soon

How can one model polymorphism in django 3.0? I.E. I have a class Vehicle then I have the classes Plane, Car, Tank, Bike that all inherit the Vehicle class.

Basically I either want django to recognize the Relationships OR I want to mirror all changes to tables of subclasses up to the Vehicle table.

How can one model polymorphism in django 3.0? I.E. I have a class Vehicle then I have the classes Plane, Car, Tank, Bike that all inherit the Vehicle class. Now I want to be able to select all Vehicles (aka getting the objects of all subclasses ( Plane, Car, Tank, Bike )) and set a subclassagnostic foreign key to Vehicles
Basically I either want django to recognize the Relationships OR I want to mirror all changes to tables of subclasses up to the Vehicle table.

hi, I made a blog site in this site If I click on a posts author name It refers me to users other posts, I know how It works but the question is how do I refer it to authors profile I already have users profile template, what should I do?

native tide Mar 29, 2020, 11:27 AM

#

Are you using Flask or Django?

#

Django

#

@native tide

#

So, inside of an href you will use {% url 'blog-home' %} 'blog-home' is an example of a name for view attached to the urlconf like this

urlpatterns = [
    path('', PostListView.as_view(), name='blog-home'),
    path('user/<str:username>/', UserPostListView.as_view(), name='user-posts'),
    path('post/<int:pk>/', PostDetailView.as_view(), name='post-detail'),
    path('post/new/', PostCreateView.as_view(), name='post-create'),
    path('post/<int:pk>/edit/', PostUpdateView.as_view(), name='post-update'),
    path('post/<int:pk>/delete/', PostDeleteView.as_view(), name='post-delete'),
    path('about/', views.about, name='blog-about'),
]

#

<a href="{% url 'password_reset' %}">Forgot Passoword?</a>

#

I wanna refer It to the authors profile not the users own profile

nimble epoch Mar 29, 2020, 11:34 AM

#

@native tide also you can create a url that redirects it like redircet(“profile”, id=user.id) in the main page that you want to click on the username

native tide Mar 29, 2020, 11:34 AM

#

in url conf you make a url configuration that takes a variable

#

for example look at this one

#

path('user/profile/<str:username>/', ...etc

#

and then just set up a view that takes the argument and redirects there

#

I might not be the best at explaining it because i dont use django very much

#

So I need a separate template for authors profile?

nimble epoch Mar 29, 2020, 11:36 AM

#

Yeah

native tide Mar 29, 2020, 11:37 AM

#

Yes, not for each profile, but in the template youll use jinja to display content based on which user it is

#

Is jinja a separate library of django?

#

oh well actually, its just similar to DTE.

#

Theyre slightly slightly different

#

Django originally used jinja i think

#

and then made it thier own a little

#

I guess I already have It in Pycharm

#

I have an error in the web browser that is blowing my mind. PyCharm says it finds no error

#

AttributeError
AttributeError: 'str' object has no attribute 'c'

#

And I know that sounds like a typo... but I cant find it

#

Its simply a spell mistake

#



        else:

            table = cls.__table__

            if declared_columns:

                for c in declared_columns:

                    if not table.c.contains_column(c):

                        raise exc.ArgumentError(

                            "Can't add additional column %r when "

                            "specifying __table__" % c.key

                        )

        self.local_table = table`

its referring to this as c I think

#

sorry for that ugly code

#

its from the debug browser

#

Its some error on my models file because I barely understand what im doing

#

SQLA is so much more complicated than Django ORM

#

!paste

lavish prismBOT Mar 29, 2020, 11:41 AM

#

Pasting large amounts of code

If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pydis.com/

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

native tide Mar 29, 2020, 11:41 AM

Its blowing my mind too 😂 cuz I'm not too much familiar with all things yet

that was weird

Dude I'm doing coding for only one month but now I guess I'm getting it

#

Good feeling when you can help someone, i know how it is.

#

yep

#

I will say, Django is definitely a steep curve for only one month in but if thats what you want you can do it

#

Its my first project but If you wanna see I can show you Its fully functional now I'm just improving it

#

damn maybe thats not it... Im going to have pour over this code. I might be too sleepy to do well rn ha Ive been awake all night...

#

Sure

#

same

#

well I'm gonna look again If I can find anything

#

but are you still getting the same issue?

I mean the same error?

ill find it

#

Read these two lines carefully

if not table.c.contains_column(c):

``` @native tide

#

maybe i just need to stop all the data and restart...

#

i thought i did that

#

i should just take a break from this, im starting to forget silly things

#

i hope thats it

#

I guess Its not defining this 'c'

📎 unknown.png

#

haha well i cant even get into the shell to drop it

#

yeah that is not my code, that is a lib so it measn...

#

something i have done has broke stuff

#

and its not obvious what except that maybe dropping all the data will work

#

that cant be it because... i put in an entirely different database. same error. It has to do with my relational mapping being horrificly bad.

#

that is what it is lol

#

SQLA is hard

#

to be fair my database is a little overly complex for a first database but whatever

#

Dude I tried but yet Its not my thing xD

#

its all good i think im too tired to deal with it now, It involves going back over everything i added and removing it or waiting for database expert to correct me. ha

#

thanks tho

#

can i ask a question about flask here?

i'm trying to make a registration form but i'm failing miserably 😦

lavish prismBOT Mar 29, 2020, 12:04 PM

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.

so

#

feel free

#

i've defined the form in forms.py

class UserRegistryForm(FlaskForm):
    name = StringField('Name', validators=[DataRequired()])
    email = StringField('Email', validators=[DataRequired()])
    password = PasswordField('Password', validators=[DataRequired()])
    submit = SubmitField('Register')

#

like so

#

right?

#

this is mine

#

class RegisterForm(FlaskForm):
    email = StringField(email_name,
                        validators=[DataRequired(),
                                    Length(min=4, max=32),
                                    Email()],
                        render_kw={"placeholder": email_name})

    password = PasswordField(password_name,
                             validators=[DataRequired(),
                                         Length(min=8)],
                             render_kw={"placeholder": password_name})

    password_confirm = PasswordField(password_confirm_name,
                                     validators=[DataRequired(),
                                                 EqualTo('password')],
                                     render_kw={"placeholder": password_confirm_name})
    submit = SubmitField('Sign Up')

#

wait

#

i just need to get a really basic one going first

#

right, so what isnt working about it?

#

@app.route('/register', methods=['GET', 'POST'])
def register():
    registerForm = RegisterForm()
    if registerForm.validate_on_submit():
        flash('Registration requested for user {}, remember_me={}'.format(registerForm.username.data, registerForm.remember_me.data))
        return redirect('/index')
        

    return render_template('register.html', registerForm=registerForm)```

#

then i define this in routes

#

and then i have a register.html file

#

{% extends "index.html" %}

{% block body %}
    <body>
    <h1>Create an account</h1>
    <form action="" method="post" novalidate>
        {{ registerForm.hidden_tag() }}
        <p>
            {{ registerForm.name.label }}<br>
            {{ registerForm.name(size=32) }}
        </p>
        <p>
            {{ registerForm.email.label }}<br>
            {{ registerForm.email(size=32) }}
        </p>
        <p>
            {{ registerForm.password.label }}<br>
            {{ registerForm.password(size=32) }}
        </p>
        <p>{{ registerForm.submit() }}</p>
    </form>
    </body>
{% endblock %}```

#

Unrelated but you should use f-strings instead of .format when you can. im looking and comparing it to mine hold on

#

Internal Server Error

#

mm

#

ok thanks!!

#

does that happen when?

#

does it happen as soon as you load site or when you click submit to register?

#

I'm not seeing what you're doing wrong other than little things tbh but im moments away from passing out.

#

good luck

the only thing that fixes it is removing this of all things

i just want to do a really basic one

#

like not linked to any database or anything

#

so in forms i have this py class UserRegistryForm(FlaskForm): name = StringField('Name', validators=[DataRequired()]) email = StringField('Email', validators=[DataRequired()]) password = PasswordField('Password', validators=[DataRequired()]) submit = SubmitField('Register')

nimble epoch Mar 29, 2020, 1:57 PM

Ohh seems easy

native tide Mar 29, 2020, 1:58 PM

that look ok?

then in routes i have this ```py
@app.route('/register', methods=['GET', 'POST'])
def register():
registerForm = RegisterForm()
if registerForm.validate_on_submit():
flash('Registration requested for user {}, remember_me={}'.format(registerForm.username.data, registerForm.remember_me.data))
return redirect('/index')

return render_template('register.html', registerForm=registerForm)```

but the bad news is, it redirects me back to the start page

it doesn't load a form

nimble epoch Mar 29, 2020, 2:15 PM

What?

like i click register

i doesn't change to a register page

well the URL changes but the page hasn't changed

          <li><button class="plain-button" onclick="window.location.href='/register';">Get Started</button>

thats the button

nimble epoch Mar 29, 2020, 2:17 PM

You mean when you click on the register it dosnt bring you to the register page?

yeh

Give it a link

I always use <a> tag and give it the class to make it like a button

Did it work?

it works fine for the login button using this method

i can send them if you want

nimble epoch Mar 29, 2020, 2:25 PM

But use request.method = “GET”

#

Maybe works

native tide Mar 29, 2020, 2:25 PM

#

where?

nimble epoch Mar 29, 2020, 2:25 PM

#

Use it inside your register route

#

Exactly after def register()

native tide Mar 29, 2020, 2:26 PM

#

def register() request.method="GET":
    registerForm = RegisterForm()
    if registerForm.validate_on_submit():

        return redirect('/login')
        

    return render_template('register.html', title='Register' registerForm=registerForm)````

Has anybody ever setup AWS RDS with flask_sqlalchemy?

I've used sqlalchemy with AWS RDS aurora Postgres before

It behaves no differently from a normal postgres database

You just have to make sure you can access it from the VPC it's in

If you're trying to get to it from your local machine you can set up an ec2 instance in that VPC to be an SSH tunnel proxy for your local running code

how hard would it be to make your own vpn?

for me? impossible

#

for someone who knew something about networking? dunno

tired root Mar 29, 2020, 5:46 PM

#

If you know basic routing, not very difficult

#

You can try it out with your computer and a phone

#

dont even need an app

#

However, what gets sold as VPN these days, isn't really the definition of VPN

quasi ridge Mar 29, 2020, 5:50 PM

#

to me, VPN means "encrypted"

tired root Mar 29, 2020, 5:51 PM

#

VPN means a private connection between two trustworthy networks over an untrustworthy medium

#

So, connecting to a VPN server to feed internet into the other side, which is untrustworthy, isn't really a vpn

#

using HTTPS is enough encryption

native tide Mar 29, 2020, 6:07 PM

#

yeah, I no longer really care for commercial VPN anymore.
I dont particularly like my ISP (or any ISP), but I'm not sure that modern VPN sold by proprietary businesses is really in the spirit of privacy exactly.
It has a use case... but its not a cure all for ownership of your home and what goes on it or anything.
If its contrary to profit, they will not uphold privacy, not unless they take it a little more seriously than they seem to.
They are essentially just middle men holding on to this data and I'm not seeing anything that verifies no logging and frankly not feeding whatever to machines to process for further business ha.

But yeah, I had PIA about a year ago and they have been bought out by scumware.

I like this https://www.vpngate.net/en/ because it's run by an educational instittuion at primarily a Japanese university in attempts to spread Internet and info to places where it is being supressed.

They are good for temporary use cases if you need a proxy IP for some reason. But overall, its not a perfect privacy solution at all.

tired root Mar 29, 2020, 6:07 PM

You are just giving your browsing behaviour to the vpn provider instead of your ISP

native tide Mar 29, 2020, 6:07 PM

exactly

tired root Mar 29, 2020, 6:07 PM

at least your ISP is in the same country and you can sue them should violations occur

I am using end-to-site VPN for free Wifi

native tide Mar 29, 2020, 6:08 PM

#

Thats true you def have to pay attention to where you geta VPN service from

tired root Mar 29, 2020, 6:09 PM

#

and due to my work, I see what kind of traffic comes out of some vpn providers

#

can't go into specifics, but it's awful

native tide Mar 29, 2020, 6:10 PM

#

Its hard to use those commercial VPNs because they are so constantly getting shut down. People act like you are the shadiest around for using it. I dont care for that sentiment either. But yeah.

#

Like services are regularly fighting them is what i mean

#

you have to jump ips frequently

#

to keep service

tired root Mar 29, 2020, 6:11 PM

#

VPN's use data centers, not ISPs

native tide Mar 29, 2020, 6:14 PM

#

I like the idea in theory. But after paying for various services and watching their behaviour and looking at the reality of it, it is not something i would rely on if there was something truly grave that not be in data or something. If. There is a use case for it but... its not "got VPN am protected" kind of thing.

#

I typically will configure one of those proxies and use if i need to to get through some service that is being dildoish and then ill drop out of it after

#

tbh i dont typically need to do that

#

but it happens

tired root Mar 29, 2020, 6:15 PM

#

There is also the issue of IPV6 and DNS leaking, which many do

Then, websockets

I actually know almost nothing about ipv6

I can identify them from looking at them

#

but thats it

It's really the same as IPV4, for the grand scheme of it

Guys im stuck between django and flask

#

Which one is better and more common for a web application

#

?

feral minnow Mar 30, 2020, 3:52 PM

#

hmm Im just a beginner with these stuff but I always hear that flask is easier to start than django so I think you have to start with flask then go to django its more professional

rigid laurel Mar 30, 2020, 3:52 PM

#

Django is very good if what you're doing fits the model it was designed for. E.g storing, querying, and presenting data to the user

#

Flask is better if you want to do extra things on top, or customise the way you do things

#

I think if your end goal is a web app with a database, then Django is probably easier to get started with - you don't have near as many annoying set up barriers

Hey, I see here keywords like Django and Flask. Possibly you could help me.
I have a question connected with dbs and Django orm.

from django.db import models
class Family(models.Model):
  pass
class Parent(models.Model):
  name = models.TextField()
  family = models.ForeignKey(Family, related_name="members")
class Boy(Parent):
  favourite_car = models.CharField(max_length=10)
class Girl(Parent):
  favourite_doll = models.CharField(max_length=10)

actually I need serializer to present Family and it's members

class FamilySerializer(serializers.ModelSerializer):
   members = ... ??

I've got an idea how to serialize separetly.. to make members = serializers.SerializerMethodField() but I cannot find out how to separate Boy from Girl
Actually as a result I want to receive something like:

# family object
{
  members: [
    { # a boy
      name: "Karl",
      favourite_car: "Dodge"
    },
    { # a girl
      name: "Ann",
      favourite_doll: "Barbie"
    }
  ]
}

@rich bobcat Is there any meta fields for example (Family()).mebmers.find_one().meta.class_name == "Boy" ?

#

@nimble epoch These kind of snarky comments won't get you anywhere

#

People here are often just idling while doing other stuff

#

But anyway, it is a matter of taste and usage. I like flask because it is simple and allows me to do things my way, while Django is more strict in my opinion.

nimble epoch Mar 30, 2020, 4:30 PM

#

I have worked with django and flask already

#

But not sure about popularity and of course about salaries im not sure

#

And django is not that hard

#

But i myself think flask in more fun

tired root Mar 30, 2020, 4:32 PM

#

What does popularity have to do with it?

nimble epoch Mar 30, 2020, 4:32 PM

#

You wat im saying

#

Popularity i mean jobs that you can find

tired root Mar 30, 2020, 4:34 PM

#

I've also never said Django is hard

rigid laurel Mar 30, 2020, 4:34 PM

#

Salary depends on where you're based. Look at local job postings

nimble epoch Mar 30, 2020, 4:34 PM

#

Django’s is more

rigid laurel Mar 30, 2020, 4:34 PM

#

If you're just looking to build a portfolio, it doesn't really matter which of the two you use

nimble epoch Mar 30, 2020, 4:35 PM

#

Yeah ya right too

#

How about communities

#

Which One has more community

rigid laurel Mar 30, 2020, 4:37 PM

#

Django probably has a bigger community - but thats because it does more things. With Flask you need to branch out and use other libraries, you don't need to near as much with Django

#

although again, I'm not sure why it matters

nimble epoch Mar 30, 2020, 4:37 PM

#

You yaslef which one ya prefer

rigid laurel Mar 30, 2020, 4:38 PM

#

I already explained my approach to two

nimble epoch Mar 30, 2020, 4:39 PM

#

That’s alright

#

But which one yourself use

rigid laurel Mar 30, 2020, 4:42 PM

#

Flask is better if you want to do extra things on top, or customise the way you do things```

#

I use both, the right tool for the job

nimble epoch Mar 30, 2020, 4:42 PM

#

Ok thanks

rich bobcat Mar 30, 2020, 5:22 PM

#

Hey I would like to ask some question. Is there way to separate fields in DRF serializes to fields for serialization and deserialization.
It's like:

class MySerializer(serializers.ModelSerializers):
  class Meta:
    model = MyModel
    fields = ("name", "last_name",)
    deserialize_fields = ("id", "name" "age", "last_name",)

to make asymmetric parsing?
I have an assumption, but I am not sure. Are fields connected to serialization, but in the opposite way it will parse everything?

feral minnow Mar 30, 2020, 8:05 PM

#

Hey guys I have this flask code ```
@app.route("/link-mp31")
def converter(file,fileName,folderPath):#File converter (from mp4 to mp3)

filePath=path(file)#Get the file path

video=VideoFileClip(file)#Create the object
    
video.audio.write_audiofile(f'{folderPath}\\{fileName}.mp3')#Convert the file

video.close()
return render_template("download.html", filePath=filePath)```

#

How I can give its arguments a value from another function/app

rich bobcat Mar 30, 2020, 8:26 PM

#

It sounds weird. Just call it as proxy:
your_vars = [file, fileName, folderPath]
@app.route()
def route_handler():
  return converter(*you_vars)
def converter(*args):
or create decorator, or functools partial

frosty mauve Mar 30, 2020, 8:35 PM

Here.

queen bough Mar 30, 2020, 8:37 PM

#

@frosty mauve Can't you do this - once the input has been got from the user, create a model with a path attribute?

#

BTW, do you have the link I sent?

frosty mauve Mar 30, 2020, 8:37 PM

#

https://docs.djangoproject.com/en/2.2/topics/files/

Managing files | Django documentation | Django

#

Well that is what I am getting confused with. I download an image and want to set the ImageField to the image but I think it has to do with like upload_to putting it in a weird place. I can manually override it with a static url and it will work but when I use save() on it creates a url that doesn't link properly

queen bough Mar 30, 2020, 8:40 PM

#

@frosty mauve As you can see, you can choose the folder (in the example's case it is cars).

frosty mauve Mar 30, 2020, 8:40 PM

#

I also was reading about how maybe just create a separate model named Images and link it to the car object, not sure if that is standard practice though

#

is cars in static or media though?

queen bough Mar 30, 2020, 8:42 PM

#

media I think. What was your problem again (sorry, I've forgotten)

feral minnow Mar 30, 2020, 8:43 PM

#

guys how i can let the user download a file from a website using flask?

frosty mauve Mar 30, 2020, 8:44 PM

#

I want to create a new obj with a photo stored locally so I don't have to manually click upload image in a GUI over and over

queen bough Mar 30, 2020, 8:44 PM

#

Oh right, automatically add all the images as models?

frosty mauve Mar 30, 2020, 8:44 PM

#

essentially create a bunch of new cars with their respective photos

queen bough Mar 30, 2020, 8:44 PM

#

That's all?

frosty mauve Mar 30, 2020, 8:44 PM

#

Yes

#

newcar = Car(name='Stupid Car', photo='') and it actually work lol

#

It works fine if I use admin

queen bough Mar 30, 2020, 8:45 PM

#

So what's the problem with that?

frosty mauve Mar 30, 2020, 8:45 PM

#

Let me give you exact problem brb

queen bough Mar 30, 2020, 8:45 PM

#

Sure.

frosty mauve Mar 30, 2020, 8:48 PM

#

ok so if I set the image field = to the path of the image

#

and then save, then call image.url it gives media/originalpathtoimage

#

media in the front?

queen bough Mar 30, 2020, 8:49 PM

#

I see.

#

I think you can set absolute path?

#

One sec.

#

Can you send the code that you are using?

#

To create the model @frosty mauve .

frosty mauve Mar 30, 2020, 8:52 PM

#

class Book(models.Model): image = models.ImageField(upload_to='images/', default='example.jpg')

queen bough Mar 30, 2020, 8:54 PM

#

Hmm, I see your problem.

#

Can't you have the images in the media folder?

#

It's been a while since I've used media, but it is fine once you set it up correctly.

frosty mauve Mar 30, 2020, 8:55 PM

#

I could try that, I was under the impression through reading online that media is reserved for user uploaded content

queen bough Mar 30, 2020, 8:55 PM

#

So is the issue creating models or opening the files from Django?

frosty mauve Mar 30, 2020, 8:55 PM

#

Create an object from the model with the image field populated and working

queen bough Mar 30, 2020, 8:56 PM

#

MEDIA_ROOT this is the absolute path to the folder that will hold our user uploads. For example MEDIA_ROOT = "/User/Timmy/Sites/Pho/root/media/".

#

Is that set correctly for you?

frosty mauve Mar 30, 2020, 8:57 PM

#

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

queen bough Mar 30, 2020, 8:57 PM

#

OK, and you have all the files already in media?

frosty mauve Mar 30, 2020, 8:59 PM

#

I do

#

I had them in static but now I have them in static and media

#

oh

#

Okay, so it works when I use media to upload from

queen bough Mar 30, 2020, 9:00 PM

#

Yeah?

frosty mauve Mar 30, 2020, 9:00 PM

#

I used admin though

queen bough Mar 30, 2020, 9:02 PM

#

I see. Now it should be easy to replicate from shell

#

Do you know how to create models from the shell?

frosty mauve Mar 30, 2020, 9:03 PM

#

Here is what I will do

#

`from books.models import Book

newbook = Book()
newbook.image = 'pathtoimage'
newbook.save()`

queen bough Mar 30, 2020, 9:04 PM

#

Yup, and you can use a for-loop

#

To load all the images in media/

#

Know how to do that?
