Git Server @ NAS receives code -> Post receive script runs -> tells Pi to do it's work and runs the above script
I am sure there are lots of ways to do this
native tide
Would I be able to add markdown editor on static site and create posts that way ?
tired root
sure, but then the server would need to be able to build jekyll and you have a backend again, which can be attacked
at that point you can use wordpress again
The point is to have no scripts that can be attacked
native tide
I don't want wordpress
Pipeline will deployed and it will be secured with no passwords

I had already stomach pain doing the rest api
But the alternative is to download all articles of the site in a json and use javascript for the search

I am doing REST API in flask, I have function that I want to implement
native tide
Scheduled job to get list of my Git repos and create table with info
tired root
https://rest.tuxstash.de/search.php?search-pattern=icinga That is my rest point
tired root
No, it is a static site generator, but I am using a REST-like API in PHP to enable a search
tired root
of course, but i'd use it only for a search
native tide
I would use Flask for REST
and table
Using Github webhooks I would pull all my repos
and sort into database that would be visualized as table
tired root
Everything on my website (https://tuxstash.de/) is static, the only thing done in PHP is the search

I have trouble with input pattern. I need it to be in format: AAA-000. First 1 - 3 letters, followed by - and then 1 - 3 numbers
So far I have tried
pattern="[A-Za-z]+-+[0-9]"
flat eagle
for regex?
tired root
^[A-z]{3}\-[0-9]{3}$
flat eagle
don't need to \-
^ and $ also apply for start / end of line
so may not be wanted / required
elder nebula
hmm. How do I make it that there is 1 - 3 letters and 1 - 3 numbers. Now its 3 for both
tired root
[A-z]{1,3}\-[0-9]{1,3}
flat eagle

elder nebula
Ok
tired root
Also https://regexone.com/ for interactive exercises
elder nebula
Thanks for helping me out. 
flat eagle
regex is a super useful thing to learn
elder nebula
Yeah
flat eagle
it gets poopoo'd a lot for being a bit weird to read
but sometimes it's the best way to solve a problem
elder nebula
Yeah. I use that for contact field, so they can't type random things.
tired root
@elder nebula But remember to also validate server side. In case you are only using JS for this.
flat eagle
and never, ever ever, EVER, write your own regex for checking if an email address is valid
someone else has done it way better than you ever will
just use that.
junior cloak
yeah regex is incredible when used in the right situations
it's also what broke a chunk of the internet for half a day earlier in the year because of a single regex a cloudflare employee messed up
(that's just a funny story to me, and not poor anecdotal evidence to say dont use regex)
that said, i see it employed a lot in python in what ifeel is not the "right" situation. if you are just trying to parse/extract data of a known or repeated structure, there are far better things. if youre scraping html, there are better things. if you are doing validation for common structures (email addresses, ip addresses, whatever) then there are far better things.

how do i make a contact page for my flask Website
my contact page looks like this at the moment https://kenny-hoft.herokuapp.com/contact
do i do it with flask-wtf ?
can i have some suggestions for useful tutorials
on Flask forms
flask wtf forms
junior cloak
@native tide sure, you can use flask-wtf. just use the official tutorial on their site! https://flask-wtf.readthedocs.io/en/stable/quickstart.html
no need for crazy and most likely outdated tutorials... a contact page is what, a couple of fields and a submit button? nothing wild, the official docs should help you out 🙂
junior cloak
easily the biggest thing i find myself dealing with when helping folks in here is when someone has been using some horribly outdated tutorial from 7 years ago and it being so outdated or incorrect that it hurt way more than it helped
native tide
yep i
junior cloak
and with flask stuff, just because its peak of tutorial writing and hype and stuff was in around that period, google searching for flask-related tutorials often overwhelmingly returns things super outdated that would may still work, may not, but definitely are not the best path to go down to learn these things in 2019
the official docs for all the flask extensions are usually the best, and the best flask extensions are well-maintained by mostly the same core people
native tide
yeah ik
junior cloak
honestly i'd search google and tell it to limit results to within the last 3-4 years, haha. i do this all the time
native tide
cuz i just recently went to a website beside the official flask doc and the tutorial was from 2013
junior cloak
and whatever you do, dont use one of the horrible 'set up flask with nginx/apache/whatever on centos/nginx/whatever' on digitalocean
but it looks like you are using heroku which is great and you can just skip all that nonsense anyway
good luck!

hey there
i am using flask in python to code my first website
i have created everything i need but i need now to launch flask
i am being told to use (venv) $ flask run however flask run comes up as 'run' is not recognized as an internal or external command, operable program or batch file.
native tide
You should do:
venv/Scripts/python (nameofyourfile)
cyan wolf
im looking to start my website
are you meaning go to the main overseeing file directory?
native tide
Do you want to run your script?
cyan wolf
no
native tide
You want to launch it on a live server?
cyan wolf
i know
native tide
You can use heroku
cyan wolf
i have those
native tide
A requirements.txt file?
cyan wolf
i am following this here: https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world
so i have venv and .idea
cyan wolf
i am following it step by step
look at the bottom
this is where i am at
flask run isnt working
thats where the issue is
cyan wolf
windows
native tide
Ok. Where are you typing in flask run
cyan wolf
PycharmProjects\website>
native tide
In the terminal?
native tide
Great
cyan wolf
sarcasm?
native tide
Is your virenv in the websitt folder?
cyan wolf
website\venv>
native tide
If it is then type: venv/Scripts/python (name of yout python script)
native tide
The one where you have if __name__ == '__name__': at the end
native tide
Can i see your directory
cyan wolf
and type the filename which ive done app = Flask(__name__)?
native tide
yes
cyan wolf
just the filename?
native tide
Run thay file
native tide
Yeah the filename and the extension
cyan wolf
ok im in scripts>
native tide
Do you use the run button in the top right? Cuz you are using Pycharm right
native tide
No
cyan wolf
:/
native tide
Venv/Scripts/python init.py
cyan wolf
what are you wanting me to do, you said just type the file name
what
venv\Scripts\__init__.py?
you really arent making too much sense
native tide
Yeaahh
native tide
You should type that in the terminal
cyan wolf
what?
ok here
i tell you what
im in PycharmProjects\website\venv\app>
what do i do from here?
tell me what to type
because you arent making much sense anymore
native tide
Remove app so your in PycharmProjects\website\venv
native tide
Then from there go to \Scripts
native tide
Then \python __init__.py
cyan wolf
type \python __init__.py?
native tide
Yes
cyan wolf
into console
ok
'\python' is not recognized as an internal or external command,
operable program or batch file.
native tide
Remove the " ** "
cyan wolf
i havent got any **
i entered \python __init__.py
\python isnt a command
that is the issue
native tide
Can i see your directory
cyan wolf
as in full expanded one?
native tide
Yeh
cyan wolf
that is it
native tide
The parent first
native tide
And enter venv\app\python __init__.py
junior cloak
your app is inside your venv and it should not be
cyan wolf
if i type venv\app\python __init__.py then it says 'venv\app\python' is not recognized as an internal or external command, operable program or batch file.
oh shit
it isnt
thatll be why
native tide
Yep @dkh i discovered that too
cyan wolf
thats that sorted
junior cloak
uhhh
native tide
The app folder needs to be outside
native tide
It needs to be in the website folder
cyan wolf
it is now
native tide
Ok ok
cyan wolf
this is my website folder:
native tide
Good
junior cloak
you need to source the venv to do so
cyan wolf
what does that mean?
junior cloak
not just run python on it
cyan wolf
ive done add FLASK_APP=microblog.py
junior cloak
do you understand what the venv is?
native tide
I think thats a command for linux users
cyan wolf
export FLASK_APP=microblog.py is linux
native tide
Open a terminal in your website folder
Type:
venv\Scripts\python app\__init__.py
cyan wolf
there is no python add directory
and also
you cant type venv\Scripts\python app\ because it isnt a command
junior cloak
what is inside the venv
cyan wolf
cyan wolf
yes
File "app\__init__.py", line 5, in <module>
from app import routes
ModuleNotFoundError: No module named 'app'

from app import routes is the issue

from wtforms.validators import DataRequired
class ContactForm(FlaskForm):
name = StringField('Name')
email = StringField('Email')
password = PasswordField('Password')
message = TextAreaField('Message')

this is the app i should run:
from forms import ContactForm
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/contact', methods=('GET', 'POST'))
def contact():
form = ContactForm()
return render_template('contact.html', form=form)
if __name__ == '__main__':
app.run(debug=True)
and when i run it, i get an error message :KeyError: 'A secret key is required to use CSRF.'
tired root
Do you even read documentation? I mean, I am the first to complain about the bad docs of flask, but these basics are in there.
Just create a secret key in your app object and you are set
app.secret_key = "CHANGE THIS"
@native tide
native tide
oof! yeh
vagrant adder
@cyan wolf your app folder is inside venv right?
drag it out of venv
@native tide
app.config["SECRET_KEY"] = "some_random_string_that_is_very_super_duper_secret"

so that works too
cyan wolf
@vagrant adder app is not in venv

can you send a picture of your project structure?

@cyan wolf I also suggest using blueprints. Makes the whole modular approach easier

I'm getting an error when running the uwsgi command with virtualenv. (Running on Ubuntu 18)
ModuleNotFoundError: No module named <module_name>
unable to load app 0 (mountpoint='') (callable not found or import error)
It works when I run my program with the python command while in the virtualenv. But when using the uwsgi command it gives me the error. I believe it's because uwsgi isn't using the correct directory where the virtual environment is located but I'm not sure how to fix it after trying several uwsgi commands and options.

What might be the best way to develop an 'activated modules' type of backend? For example, my users have a core app that they pay for and they want to purchase another module to extend the functionality. What might be a good architecture for this?
cyan wolf
ok so
sonic scaffold
You will need some object to describe the featureset the client has paid for. In the old days you might use a bitmap to efficiently store this featureset, but it's probably better to be semantic unless you need this to scale incredibly large - so an array of subscription information.
winter shadow
Nowadays, I can probably get away with creating a 'permissions' object on my 'users' mongo collection?

Not sure, haven't worked with mongo much

Hi, so I have 5 html files with javascript in a <script> tag. I've gathered them using XMLHttpRequest all fine and printing out the javascript to console is good, but when I add them to a div element in index.html, the "<" character I use as the "smaller than" operator in javascript creates a new tag. I basically want the javascript to look exactly like the output when using console.log(). I fixed the \n with white-space: pre-wrap, but now I have the < problem.

hey guys, I have a question about APIs... Idk if it fits this channel but here it is:
Say there is a web API accessible via POST requests. The said API has rate limits and sometimes it can be slammed - meaning if you request a big chunk of data at one hour it would work but in the other hour you have to split it in smaller chunks to get an actual response. So my goal is to build a rather robust wrapper for this API (in python ofc, using aiohttp). By robust I mean: intsead of hitting a rate limit due to many simultaneous calls I want it to build a queue if needed and I want it to detect if API call fails and send it again requesting smaller chunks of data
I think about approaching this problem as following: create an API class which on init will create a session and will contain as attributes (idk yet class or instance attributes) API rate limits. Then whener any kind of API call is made it should call some wrapper method who's goal it to handle a queue/rate limits and which in turn will turn call the internal class method that will make an actual API call.
Is it a sound idea? And is it similar to a typical way of approaching API wrappers?

please help
native root
That occurs if you do not initialize your form
Your flask function that returns the rendered template should be creating the form with ContactForm()
It will also happen if you override __init__ and forget to call super()
native tide
so this is what the function looks like ```@app.route('/contact', methods=('GET', 'POST'))
def contact():
form = ContactForm
if request.method == 'POST':
return redirect('/email_sent')
return render_template('contact.html', form=form)
did it happen because i forgot the parenthesis
yeah yeah
vagrant adder
yes
native tide
i didn't get the third sentence you wrote
override __init__ and forget to call super()?
what does it mean
native root
It applies to subclassing
For example, if you wanted to do this:
class ContactForm(FlaskForm):
username = StringField('username')
def __init__(self, many_usernames):
if many_usernames:
self.username = ListField(...)
class ContactForm(FlaskForm):
username = StringField('username')
def __init__(self, many_usernames):
if many_usernames:
self.username = ListField(...)
super().__init__()
Note that the first one is missing super().__init__()-- in this case, that makes sure that the form gets set up correctly. It's also generally good practice. What it actually does, is it calls the parent class's __init__ function. If you don't know what that is, don't worry about it for now, it'll make sense later
native tide

if form.validate_on_submit():
app.config['MAIL_SERVER'] = 'smtp.gmail.com'
app.config['MAIL_PORT'] = 25
app.config['MAIL_USE_SSL'] = True
app.config['MAIL_DEBUG'] = True
app.config['MAIL_USERNAME'] = form.email.data
app.config['MAIL_PASSWORD'] = form.password.data
app.config['MAIL_MAX_EMAILS'] = 3
msg = Message(f'from {form.name.data} of your website',

Hey folks. This is a web dev/database question, so I'm not really sure where to ask, but I'm building a template that will display different products. I have:
class Product(db.Model):
id = db.Column(db.Integer, primary_key=True)
product_name = db.Column(db.String, nullable=False, index=True)
product_info = db.relationship('ProductInfo', backref='product')
def __repr__(self):
return f"Products('{self.title}')"
class ProductInfo(db.Model):
id = db.Column(db.Integer, primary_key=True)
prod_id = db.Column(db.Integer, db.ForeignKey('product.id'))
subtype = db.Column(db.String, index=True, nullable=False)
overview = db.Column(db.Text, index=True)
features = db.Column(db.String, index=True)
options = db.Column(db.String, index=True)
def __repr__(self):
return f"ProductInfo('{self.subtype}')"
so far
But it's now hit me that overview and features need to be lists
Which I guess means I'll need to make a table for each. But It's going to be difficult to keep track of each item in each list for each product. Is there a best practice anyone can point me towards for this?
native root
The question is, lists of what
In your case, for features, it's a good idea to have a Feature class, of which every feature is an instance of. Then you attach it via a many-to-many relationship to productinfo, which lets features be attached to many products. Or, a many-to-one, if each feature is going to be productinfo specific

Hey all! I'm currently working on deploying a small Flask app, and as things stand I'm having to seed my DB with initial data 'manually' each time.

Hi! I'm working on my first Flask app and I wanted to test it out with pytest but I can't figure out how to work with session objects through these tests, does anyone know how ?
ebon beacon
So I'm following this tutorial for creating REST APIs using Flask
I've pretty much done everything and it all seems to be working fine
Then I added a new model
updated db migrations as well
then I added the new model in the controller, but I keep getting the error in terminal
raise ValueError('Model {0} not registered'.format(name))
ValueError: Model deactivated_users not registered
in user.py, I added -
class DeleteUser(db.Model):
"""model to store list of deactivated users"""
__tablename__ = "deactivated_users"
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
user_account_id = db.Column(db.Integer, nullable=False)
in_group_id = db.Column(db.Integer, db.ForeignKey('in_group.id'), nullable=False)
first_name = db.Column(db.String(64), nullable=False)
last_name = db.Column(db.String(64), nullable=False)
user_name = db.Column(db.String(64), unique=True, nullable=False)
password = db.Column(db.String(255), nullable=False)
email = db.Column(db.String(128), unique=True, nullable=False)
deleted_at = db.Column(db.DateTime, nullable=False)
In the dto.py file, I added this as well -
class DeleteUserDto:
api = Namespace('deactivated_users', description='list of users deactivated')
deactivated_users = api.model('deactivated_users', {
'in_group_id': fields.Integer(required=True, description='in group id'),
'user_account_id': fields.Integer(required=True, description='user account id'),
'first_name': fields.String(required=True, description='user first name'),
'last_name': fields.String(required=True, description='user last name'),
'user_name': fields.String(required=True, description='user username'),
'email': fields.String(required=True, description='user email address'),
'password': fields.String(required=True, description='user password'),
'deleted_at': fields.DateTime(required=True, description='time account was deactivated')
})
and then in the user_controller.py file
from ..util.dto import UserDto, DeleteUserDto
from ..service.user_service import save_new_user, get_all_users, get_a_user, deactivate_user_account
@api.route('/<email>')
@api.param('email', 'user identifier')
class DeleteUser(Resource):
@api.response(201, 'User successfully deactivated.')
@api.doc('deactivate a user')
@api.marshal_with(_deactivated)
def delete(self, email):
"""deactivate a user account given its identifier"""
return deactivate_user_account(email)
when I type python manage.py run in terminal and then go to the url specified
I get the error mentioned above
Please how do I register the model in the dto.py file so swagger would recognize it?
ebon beacon
Lol, solved it
Turns out I need to use Blueprint to register the extra model as well

if i want to add a method for people to add text on my website .
how should i do it and what do i use?
for example: On wikipedia you can edit what's writen there
if you just click the edit button, it opens a window on the same page and it inputs a copy of the article you want to edit.
and you can just write whatever you want and publish the changes

Why is it advisable to use percentages instead of pixels when setting the size of something in CSS?
vagrant adder
@serene spoke you might just ask here, someone will answer them
i have some free time rn
cyan wolf
hey
so i have a html code using bootstrap css
https://hastebin.com/izefazilag.xml
and my website looks like the following
the rest of the page is blank
when i resize the page to a much smaller size (i think below 900) then i get it looking like this
something in the hmtl file is making the dropdown be deleted and the contents be put on the top nav bar when the page is stretched. i dont know what it is as half of it isnt my code so if anyone knows and could help, that would be amazing
notes:
changing the css file does nothing
removing <ul class="navbar-nav mr-auto"> does this:
https://cdn.discordapp.com/attachments/452874973556637698/641677133999112213/unknown.png
vagrant adder
sorry, frontend isn't my thing
proper hinge
@native tide I would say because percentages are relative. And that's important because elements of websites typically change size to adapt to different screen sizes or to account for other elements being shown or hidden.
So it's a way to have a consistent value relative to something else that may change
native tide
Thanks for your reply, Mark 👍

@native tide A button 900 pixels to the right is not visible on a 720p screen. A button 50% to the right is always visible.

Hey folks. I'm using flask-sqlalchemy and flask-migrate for a development db. My SQLALCHEMY_DATABASE_URI is set to 'sqlite:///test.sqlite'. I've run through the steps to initialize the db with flask-migrate, but when I spin up the server I get an error that basically says I've lost my connection to the db
after some debugging, I THINK the problem is that the URI is making the db generate in the project root, but the app factory is trying to find the db in it's package root
.

There's my project tree
so the initial db is generated in the project root directory, and yeah- once I spin up the server, a new test.sqlite is generated in the 'aluminum_associates' package
I'm having a hell of a time figuring out why this is happening
def create_app():

``` Here's my app factoryclass DevelopmentConfig(Config):
DEBUG = True
SQLALCHEMY_DATABASE_URI = os.environ.get('SQLALCHEMY_DATABASE_URI') or\
'sqlite:///' + os.path.join(basedir, 'test.sqlite')
``` My dev configShoot. It's pointing to the package dir
/Users/dofihasoidfjsd/apadkf/aluminum-associates/aluminum_associates
basedir = os.path.abspath(os.path.dirname(__file__))
the environment variable is returning 'sqlite:///test.sqlite' still
pliant hound
isn't the or only called when the first option isn't set?
vagrant adder
I don't know about that, but i have never used basedir for db uri
pliant hound
ah okay let me try
Bah. It's still generating the db in the aluminum_associates package
vagrant adder
Try running the app
pliant hound
I did, I even removed the 'or' part- the db is still being generated
vagrant adder
Can you paste error trace
pliant hound
The terminal is outputting this error when I spin up the server:
sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) no such table: user
[SQL: SELECT user.id AS user_id, user.first_name AS user_first_name, user.last_name AS user_last_name, user.email AS user_email, user.image_file AS user_image_file, user.password AS user_password
FROM user
WHERE user.id = ?]
[parameters: (1,)]
(Background on this error at: http://sqlalche.me/e/e3q8)
Ah
pliant hound
The link points to this:
OperationalError
Exception raised for errors that are related to the database’s operation and not necessarily under the control of the programmer, e.g. an unexpected disconnect occurs, the data source name is not found, a transaction could not be processed, a memory allocation error occurred during processing, etc.
This error is a DBAPI Error and originates from the database driver (DBAPI), not SQLAlchemy itself.
The OperationalError is the most common (but not the only) error class used by drivers in the context of the database connection being dropped, or not being able to connect to the database. For tips on how to deal with this, see the section Dealing with Disconnects.
Is your project on github or something?
vagrant adder
It seems like there's the problem
This is what i use for creating tables
When i use factory style
pliant hound
Ah, I can generate the db with db.create_all(app=create_app())
Which I guess is the same thing haha
vagrant adder
Yes
pliant hound
I did
>>> from aluminum_associates import db, create_app
/Users/alexanderlow/Documents/web-dev/aluminum-associates/aluminum_associates
>>> db.create_all(app=create_app())
And then from there, when I run flask db init / flask db migrate / flask db upgrade, it generates another db
vagrant adder
So you need to do that within app context
vagrant adder
Most probably
pliant hound
Okay, well with the db.create_all(app=create_app()) only, I'm able to spin up the server with zero errors
vagrant adder
So it works?
pliant hound
So instead of doing it with an interactive shell and I use your script, I need to figure out how to implement flask-migrate so I can update my db
Yeah! Just seems that flask-migrate is causing me headaches
vagrant adder
I had the same problem when i was tryinf to set up flask migrate
Yeah! Just seems that flask-migrate is causing me headaches
The exactly same problem i ran into last year
And i said screw this
pliant hound
Lol I'm right there with ya right now
I might just nuke the db every time I need to make a change. Idk
This has wasted more time than I'd care to admit today
vagrant adder
Lmao

Hey, guys, how do you guys check if users verification is not expired? especially for mobile number?, I am trying to detect if user fill out verification code under 60seconds. So wrote some method in django model manager. But confused to check if user actually put verification code in 60 seconds
stiff totem
@pliant hound nope, i am using Django.
pliant hound
Oh! My apologies.
I have zero experience with Django, but flask has a tool in an extension for setting a config variable for authentication
Uhh let me do some googling
I'm sure this isn't very helpful, but there's lot of documentation on Django's site about writing custom backends https://docs.djangoproject.com/en/2.2/topics/auth/customizing/
I also found this extension someone's written

So you want to keep the navbar items instead of using the burger menu on mobile devices?
If you want to mess around with which viewport width will collapse the navbar, take a look at navbar-expand-lg
try navbar-expand-md or navbar-expand-sm
cyan wolf
navbar-expand-lm seems to work amazing apart from when I compr as to 575 which then everything gets funky
However, that's fixed the main issue, thank you very much @pliant hound
pliant hound
No worries my guy 🙂
cyan wolf
So to fix the new issue, how do I make sure the nav bar doesn't change after 575
pliant hound
Hmm I'm not super familiar with Bootstrap, but you could download the source code and add your own css?
cyan wolf
I don't know how to code CSS but I can try
pliant hound
Ah, it's pretty hard to avoid once you start wanting to customize how your site behaves
prime fox
@cyan wolf
For navbars that never collapse, add the .navbar-expand class on the navbar. For navbars that always collapse, don’t add any .navbar-expand class.
from bootstrap doc
cyan wolf
Yeah so I've got one added as that gives then collapsable ability
So ill experiment with the different options
Ok so that'll be good for now
Next issue
In my nav bar, I have a drop-down and in that I have another drop-down
It currently looks like this

what is the <p> tag does if you can just write it directly?
native tide
but it does nothing to the actual text
so why is it useful
if you omit the tags nothnig happens
safe garden
that depends on the styling
you can style paragraph tags to be another font, another font size, have decorations, etc
it's to organize your code while making it clear what exactly the text is
whether it's a paragraph or something else
native tide

Any idea why this regex fails for a pattern in an <input> ?

It's to disallow those characters
giving me
Unable to check <input pattern='[^<>,^*`/´?!@|§}]){[(%$¤#£:;\=0-9]+'> because the pattern is not a valid regexp: raw brace is not allowed in regular expression with unicode flag

I’m trying to use a bootstrap template and it uses a “contact_me.php” to send email when someone fills out the fields, now I’ve gotten the bootstrap itself to work, the page shows up fine but it 404s with when submitting the page, I’ve tried completely redoing the front end even going as far as to render my own fields and set up with flask-mail. I’m honestly lost as to how I can actually implement a bootstrap template like this using flask, I’ve been beating my head against this code trying to get some understanding of it but there’s something I’m missing. Pretty much starting from scratch again, so I need someone to help me out here

No @native tide
I am trying to do something different here
I am writing a summary
And i don't want to wrap every sentence in a <li> tag
native tide
for example:
i have a large amount of text
Hij is een zakenman die veel geld had en wilde bewijzen dat hij ook veel macht had
door te trouwen met een derde vrouw.
Hij was een mohammedaan dus hij had recht op meerdere vrouwen.
Maar op de nacht dat hij zou trouwen werd hij vervloekt.Hij kreeg de <em>Xala</em>.
De <em>Xala</em> maakte dat hij geen geslachtsgemeenschap met zijn derde vrouw kon hebben.
El Hadji nam toen aan dat zijn twee andere vrouwen: 'Oumi N doye' en 'Adja Awa Astou' hem hadden vervloekt
met de <em>Xala</em>. Maar dat was niet zo.
Zijn tweede vrouw <strong>Oumi N doye</strong> was een materialistiche vrouw en voor zijn derde huwelijk was ze
vaak jaloers op de eerste vrouw van El Hadji n.l. <strong>Adja Awa Astou</strong>.
Adja Awa Astou was een goeie vrouw.Ze was niet jaloers op Oumi N Doye en ook niet op N'Gone(de derde vrouw).
El Hadji zocht naar alle soorten manieren om af van zijn <em>Xala</em> te komen. Hij en de vader van N'Gone
gingen samen naar genezers om hem te helpen van zijn <em>Xala </em>af te komen. Hij moest betalen daarvoor en
het daardoor
een heleboel schulden.Voor het laatst waren hij en de vader van N'Gone(Babacar) naar een seet-katt gegaan.```i am not going to put every sentence in the <li> tag
its going to be redundant
so i need another way
safe garden
what part of it is redundant?
it's the way that you organize the file
the <li> tags define the list items
native tide
what i just said
safe garden
and if anything, there are shortcuts for writing all those tags in within your ide
native tide
ok what's the shortcut i do not know about
safe garden
i mean some ides allow you to alt-click to insert multiple cursors so you can type the tags all at once
others allow you to wrap a paragraph in a tag
depends on the ide you have
and if you really dont want to do anything yourself, i just googled an html list generator and you could use https://www.textfixer.com/html/html-list-generator.php
or, you can practice some python and try to make a python script to do it for you
lots of different solutions
take your pick
native tide
doesn't really do it for me
what if i want to make
for example i have this:https://boekverslag2004.herokuapp.com/Xala-Sembene_Ousmane
and a user comes and wants to edit something just like you can do in wikipedia
above the paragraph there is an edit button
and you click on it and then opens a window for you with the copied text.
now you can insert or remove everything you want
and then publish it
where should i start?
native tide
Is there any way I can add an an 'action' to a checkbox in Flask? I am basically creating a to-do app and I want the item moved at the bottom whenever I tick the box and therefore mark it as complete. I took care of the backend, but I don't know how to tie this to the web page
pliant hound
If you wanted Flask to handle that functionality, you'd have to refresh the page every time you checked a box
native tide
i need some help myself
pliant hound
You want to write some js to handle it on the front end
vagrant adder
@pliant hound he can use ajax or axios to end data to server without refreshing

the jinja file being rendered is calling an attribute called "confirm_password", which is not defined

Post all of your code. All of it.
Not snippets like you've been doing so far - which gives us a peekhole into what you're doing, because it's almost impossible for me to know what you're doing right now. I have a number of guesses as to what's going on.

i got the data from a database
wet kite
Yes
native tide
ok
wet kite
What's the problem 👆
native tide
so this is where i get the data from
try:
connection = psycopg2.connect(user="postgres",
password="kenny",
host="127.0.0.1",
port="5432",
database="kenny")
cursor = connection.cursor()
# Print PostgreSQL Connection properties
if __name__ == '__main__':
print(connection.get_dsn_parameters(), "\n")
if __name__ == '__main__':
cursor.execute("SELECT * FROM Messages;")
result = cursor.fetchall()
print("The result: \n")
print(result)
cursor.execute("SELECT message FROM Messages;")
msg = cursor.fetchall()
cursor.execute('SELECT first_name FROM Messages;')
first_names = cursor.fetchall()
except (Exception, psycopg2.Error) as error:
print("Error while connecting to PostgreSQL", error)
finally:
# closing database connection.
if __name__ == '__main__':
if (connection):
cursor.close()
connection.close()
print("PostgreSQL connection is closed")
and then i did something with it first
msgs = []
names = []
for i in msg:
for message in i:
msgs.append(message)
for i in first_names:
for name in i:
names.append(name)
i want to then display the data on a webpage
by doing this
{%block body%}
<table style="border:2px solid black">
<tr style="border:2px solid black">
<th style="border:2px solid black">Name</th>
<th style="border:2px solid black">Message</th>
</tr>
<tr style="border:2px solid black">
{%for i in names%}
<td style="border:2px solid black">{{ i }}</td>
{%endfor%}
{%for i in msgs%}
<td colspan="4" style="border:2px solid black">{{ i }}</td>
{%endfor%}
</tr>
</table>
{%endblock%}```but it doesn't display it in the way i want
it to
native tide
NVM
i did this now and it worked out:
{%block body%}
<table style="border:2px solid black">
<tr style="border:2px solid black">
<th style="border:2px solid black">Name</th>
<th style="border:2px solid black">Message</th>
</tr>
{%for i,e in zip(names,msgs) %}
<tr>
<td style="border:2px solid black">{{ i }}</td>
<td style="border:2px solid black">{{ e }}</td>
</tr>
{%endfor%}
</table>
{%endblock%}```@vagrant adder hey yeah it's ok, thanks for pointing out the missing ` anyway. I'll post the registration form asap

hello again
dawn ember
I have a quick question regarding flask dance and it's ability to make put requests... is it possible or should I just use the requests library?
dawn ember
Flask-Dance is a oauth2 lib of sorts, and I'm using it to incorporate discord oauth2 into my web app. I'm just trying to gather if it's possible to make put requests with the library or if I should use the requests library
vagrant adder
as i can see, this extension is just oauth client for github. if you want to make proper requests, requests module is gonna be needed
but it's up to you what do you want to send requests to
dawn ember
yeah I'd need put requests to add roles to the user and add them to the guild
That's the only thing I'd need it for
dawn ember
discord server
nah
I'm making raw web requests to the discord api through a flask app after they login via oauth2
vagrant adder
ah
dawn ember
I was just wondering if the oauthlib I'm using would help with the put requests
vagrant adder
yes, then you gonna need requests module
dawn ember
Gotcha, thank you
vagrant adder
that oauth is only made to be able to login to some system with github/google/gitlab/slack/whatever

hey
i have the following code for the dropdown of my website
<div class="dropdown-menu" aria-labelledby="navbarDropdown">
<a class="dropdown-item" href="">Log in</a>
<div class="dropdown-divider "></div>
<a class="dropdown-item" href="">Register</a>
</div>```now it works fine, when i go to click the link, it routes to where it normally goes which is /#
however, i need to route the login and register options to my /login and /register page
im trying to use url_for to link them in like so:
<div class="dropdown-menu" aria-labelledby="navbarDropdown">
<a class="dropdown-item" href="{{ url_for(login) }}">Log in</a>
<div class="dropdown-divider "></div>
<a class="dropdown-item" href="{{ url_for(register) }}">Register</a>
</div>```but this comes up:
how would i go about linking it to my web page
its fine if i do login or register
but if i change the file name in the future, ill have to reset it here to the correct file name
oh i am a fucking idiot
i didnt put it in ' '

Hey guys
How would i deal with unique constraints in django rest_framework?
Here is my model Role ```
class Role(models.Model):
address1 = models.TextField(name="address1", max_length=150, null=True)
address2 = models.TextField(name="address2", max_length=150, null=True)
vat = models.CharField(max_length=100, null=True)
categoryname = models.CharField(primary_key=True, max_length = 100)
date_created = models.DateField(null=True)
is_active = models.BooleanField(null=True)
is_passive = models.BooleanField(null=True)
owner = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='roles', on_delete=models.CASCADE)
def get_owner_full_name(self):
return self.owner.get_full_name()
When i try to post data in my categoryfield that already exists i am getting field with that categoryname already exists error. I want to just increment the name of the field next time is chosen. Like Developer 1, Developer 2, etc.. Here is what i have tried: ```
class RoleSerializerBasic(DynamicFieldsModelSerializer ,BasicSerializer,):
owner = serializers.ReadOnlyField(source='owner.username') #
class Meta(BasicSerializer.Meta):
model = Role # Model to serialize
fields = ('address1', 'address2','vat','categoryname','date_created', 'owner')
depth = 0 # How deep we want to serialize fk connections
def create(self, validated_data):
if Role.objects.filter(name=self.validated_data['categoryname']).exists():
return self.validated_data['categoryname']+1 ```

Hey guys, your expert knowledge of Django demanded 😄 So here is the problem. I created a custom create_number manager method.
class NumberQueryset(models.QuerySet):
def create_number(self, number, user):
if number_validator(number):
if self.filter(is_verified=True, user=user, number=number).exists():
raise ValidationError("Number already verified")
else:
verification_code = generate_random()
self.create(user=user, number=number, verification_code=verification_code, operator=get_operator(number), valid_until = timezone.now()+timezone.timedelta(seconds=VALID_UNTIL_CONSTANT))
So in a views.py i created a view that get only number input from template. I have to redirect to verify page after submission of number from user. Also i have to call this method above. I tried using CreateView and created a form with following but it did not call my method unless i invoke my method manually. I tried calling it inside form_valid function scope, but since its using CreateView with ModelForm form_save method is invoking. How can i achieve this, or my approach is wrong from the first place?
class NumberRegistrationForm(forms.ModelForm):
class Meta:
model = Number
fields = ["number"]
class NumberRegister(LoginRequiredMixin, CreateView):
form_class = NumberRegistrationForm
success_url = reverse_lazy("account:verify")
Hey guys, I'm wondering if it's a good idea to structure my models like this in Django:
price = MoneyField()
is_active = models.BooleanField(_("Offer the course with this package"), default=True)
class CompleteCoursePackage(Package):
pass
class SingleLessonPackage(Package):
pass
class TryOutLessonPackage(SingleLessonPackage):
pass
I want to be able to check very easily if a Package is a specific kind and there might be more methods and attributes added later.
I'm contemplating doing it like this (using a boolean in SingleLessonPackage instead of the TryOutLessonPackage), but the version above seems cleaner to me and more consistent:
price = MoneyField()
is_active = models.BooleanField(_("Offer the course with this package"), default=True)
class CompleteCoursePackage(Package):
pass
class SingleLessonPackage(Package):
is_try_out = models.BooleanField()```You need to balance between complexity and code reuse. If a try-out is identical to a single lesson data wise, then a Boolean is the best choice IMO
Generally you should only subclass to add additional information—a lesson plan group might have a different amount of fields, and managing those unneeded fields when working with single lessons could be burdensome
Also note the multiple choice field type—this can help with categorization

hi guys im trying to learn how to deploy a flask app to heroku by doing it based on realpython's tutorial.
issue is im constantly getting a "R10 error (boot timeout) -> web process failed to bind to $PORT within 60s" when trying to get heroku to run a web command which i guess means the app couldnt bind to a port on heroku's servers(?
im using waitress-serve on a windows machine, host is explicitly set to 0.0.0.0 with no hardcoded ports in the code if that helps
would appreciate if someone could give a little help on the matter, thanks
tutorial followed is as below:

Ever heard of a Bloom Filter? This is a short video that I hope is useful to a few people. It introduces Bloom Filters after discussing hash functions and hash tables and might give you a few more options when deciding how best to design your next web app: https://youtu.be/oRGA05G421E
native tide
@native root thanks so much for your answer. I did look into the multiple choice type and basically moved it all into one single package model with a choice-field type. I assume that should make the different packages easier to use as foreignkeys in a Course model. This is the solution I came up with now. Would you mind pointing out possible advantages and risks/disadvantages against the (2nd) version with the inherited package models?
user = models.ForeignKey()
team = models.ForeignKey()
kind = models.CharField(choices=PRICE_PACKAGE_CHOICES)
price = MoneyField()
# for tryout
is_try_out = models.BooleanField()
# for class card
lesson_amount = models.IntegerField()
# for subscription
renewal_frequency = models.CharField()
def clean(self):
# Either user or team needs to be set
if (self.user and self.team) or (not self.user and not self.team):
raise ValidationError('You have to set either a user or a team.')
if self.kind == SUBSCRIPTION and self.renewal_frequency is None:
raise ValidationError('Subscriptions need a renewal frequency.')
elif self.kind == CLASS_CARD and self.lesson_amount is None:
raise ValidationError('Class cards need a lesson amount.')
@property
def owner(self):
return self.user if self.user else self.team
@property
def is_team_package(self):
return True if self.team else False
@property
def is_teacher_package(self):
return True if self.teacher else False```Advantages:
Simpler and cleaner across both your python code and database, since the singular model shows up as one type under both django's admin and as a single table, making views, templates, and everything else quite simple and easy to work with.
Disadvantages:
If in the future you want to make team/teacher packages significantly different, you'll have to split them off or manage the extra fields.
Also, needing your clean() method, since that's holding together what are called "invariants", which is usually done via subclassing. That is, a "teampackage" is a package but with team and not user, and a userpackage is a package with a user but not a team. However, if there are very few invariants it's likely much easier to simply handle them as you have, instead of dealing with admin and integrating multiple models into your code everywhere.

where can i host a web api using flask and MySQL? I tried Heroku but it asks for credit card info when trying to add a MySQL addon.
edgy dome
@vagrant adder mysql is also free on Heroku, just that it asks for credit card info for verification.
Is there any other site which also gives free DBs without asking for credit card info.
vagrant adder
Hmm
Maybe python anywhere?
Not sure about that one
I only know of heroku providing a db for free
edgy dome
@vagrant adder Thanks.
I just checked, with postgres Heroku doesn't ask for credit card info which is not the case for MySQL even though it too has a free option.
So will go ahead with postgres for now.
vagrant adder
👍
Postgres is a little bit different from mysql
But for basic querying and table creation it's great
edgy dome
@vagrant adder I am using sqlalchemy, so not much impact on the Python front.
Has anybody installed postgres on Ubuntu 19.10?
vagrant adder

edgy dome
Can you please let me know the steps
vagrant adder
I'm not home
There are forums that can help you do that
Quick tips:
- don't create dbs and tables as superuser
- don't forget the password of the user you create 😂
- only create db manually, let sqlalchemy do the tables and stuff
edgy dome
ok, but I already have a data dump exported from postgres. So looking to import it which should create the tables.
vagrant adder
And oh yeah keep credentials safe, you don't want to be raided

Hello guys. Lets say that i have Model Role with field categoryname. And i add and object with property value that already exists. If i try to create new object with property Value Developer, how would i auto increment it to Developer1 because Developer already exists? Has anyone done something similar? I am stuck on this for days, and i don't know how to solve it. Have tried lot of implementations, and failed.
I am always getting "categoryname with this name already exists", or "UNIQUE CONSTRAINT FAILED", if i remove my validators.

the way you do it is you increment id, not other field
your id in db table is incrementable by a sequence, since it's an int,
string is not incrementable by your intentions

Does anyone have any experience with creating a login using flask-login?

what are you attempting
wraith ember
Just a simple login/register system
HTML login page and just use that to store info and redirect users to pages
I have little understanding of it all
prime fox
whats the error i might be able to help troubleshoot
wraith ember
Here is what I have in my python function
def login():
if request.method == 'POST':
id = request.form["id"]
return render_template("loginpage.html", var=False) # var used to render invalid id/password
if request.form['password'] == 'password' and request.form['username'] == 'officer':
session['logged_in'] = True
return render_template("callCenter.html")
else:
flash('wrong password!')
return render_template("loginpage.html")
return render_template("loginpage.html")```and here is my html
<link rel = "stylesheet" type = "text/css" href = "{{ url_for('static', filename='content/loginpcss.css') }}" />
<div class="login-page">
<div class="form">
<form class="register-form">

<input type="text" placeholder="Unique ID"/>

$('.message a').click(function(){
$('form').animate({height: "toggle", opacity: "toggle"}, "slow");
});

Currently getting a 400 error
prime fox
you return before checking anything
def login():
if request.method == 'POST':
id = request.form["id"]
return render_template("loginpage.html", var=False) # var used to render invalid id/password
Commented out the return and still getting a 400 error\
prime fox
your html <input /> needs name attribute
wait
where's the password field
your login form lacks a lot
first you need
<form method="POST" action="/login" >
and then
<input name="username" type="text" />
<input name="password" type="password" />
so like this
<form method="POST" action="/login" class="login-form">
<input name="username" type="text" placeholder="Unique ID"/>
<input name="password" type="text" placeholder="Name"/>
<button>login</button>
<p class="message">Not registered? <a href="#">Create an account</a></p>
</form>```input type submit instead of dummy button
wraith ember
Confused as to what you mean
for the login button change it to
<type=submit button>login</button>
?
prime fox
<input type="submit" ...
wraith ember
Current HTML code with your changes
<div class="login-page">
<div class="form">
<form class="register-form">
<input name="name" type="text" placeholder="Name"/>
<input name ="ID "type="text" placeholder="Unique ID"/>
<input name ="Email Address" type="text" placeholder="Email Address"/>
<button>create</button>
<p class="message">Already registered? <a href="#">Sign In</a></p>
</form>
<form method="POST" action="/login" class="login-form">
<input name="username" type="text" placeholder="Unique ID"/>
<input name="password" type="text" placeholder="Name"/>
<input type="submit">login</input>
<p class="message">Not registered? <a href="#">Create an account</a></p>
</form>
</div>
</div>```Still getting a 400 error when I run it on localhost -- I think it has to do with the login function in python
prime fox
does this page give 400 or does the login button click give 400
you need a route to render this page
and a route to handle POST /login (which you had above)
i take your intention is:
GET /login -> render this page, POST /login -> check user name password?
wraith ember
The page gives 400
No
I want to show the page, get user login information then do stuff with that user info
prime fox
if that the case, refactor your def login() as:
- if method is GET:
- render this HTML
- if method is POST:
- get form username, password
- check user name password
- correct -> render other user pages
- wrong -> render this page with errors
hope that gives some direction
wraith ember
@app.route('/login', methods=['GET','POST'])
def login():
if request.method == 'GET':
id = request.form["id"]
return render_template("loginpage.html", var=False) # var used to render invalid id/password
if request.method == 'POST':
if request.form['password'] == 'password' and request.form['username'] == 'officer':
session['logged_in'] = True
return render_template("callCenter.html")
else:
flash('wrong password!')
return render_template("loginpage.html")
return render_template("loginpage.html")```
Based off your notes this is what I changed it to and I am still getting a 400 errorid = request.form["id"] what is this, you don't have this in your GET route
your GET is just getting the initial HTML page
wraith ember
Oh ok
Got the page to render
So, now based off of my code, when I login with officer and password as password it should redirect me to the other page?
Because when I do it hits me with another error
prime fox
if that's the logic you want, sure
wraith ember
Yeah, I am just gonna hard code users currently
prime fox
yeah, you can try text files as for starters
i recommend dipping your feet in database tho
wraith ember
Yeah, I plan on doing so but I can't figure it out so just wanna get this working at least -- I just can't find a good tutorial that helps me with it :\
Regardless, when I log in with those credentials I get an internal server error
prime fox
session['logged_in'] = True where do you get your session dict from
wraith ember
I don't know, I found that code online
prime fox
lol
wraith ember
🙃
prime fox
if you don't have that session dict how can you use it
if you check a stack trace does that point you to that line
wraith ember
works

I am busy with my website again
When i run the app.py file
And go to localhost
I see all the styling i specified in the css file
So when I test it it looks perfectly
But when I launch it to heroku
And go to my website
The css doesn't work intirely
Some tags are styled and others look basic ugly
I don't want that
I think the problem lies when i want to push it to the heroku server
It mayber reads the old css file or something?
I don't really know so can i get some help on this

in the Developer Console -> Network tab -> filter only CSS files you should be able to see CSS from the heroku server
and can compare with your local to see if deployment worked

that looks fine for the base yea. any issues?

typically sending it as a b64encoded & even then zipped string would be how you send it to the api. Let me see if I can grab an example
queen river
Ummmmmmmmmm I don't understand at all :P
I followed a tutorial but I dunno how to upload it @jade egret
Do I need to link it?

when making a request to the api, you can use a file kwarg & send the file string there. Then in the api get it from request['files']

I can't seem to find some info about it. But how would it be possible to do this:
I want to write a variable into an <input> automaticly. So if a user enters the site. An <input> box would have a value like "hello world".
I know you can do it with a <p> like this: <p>{{ variable}}</p>
And in your python file: return render_template('test.html', variable=var)
But I can't seem to find it for an input box
native root
Do you want that value to be the default input, or the ghosted placeholder value that vanishes if the user enters something?
hoary spruce
Default input
native root
input tags have the value and placeholder attributes that do either of those
<input value="text here">
hoary spruce
The use-case is: A user types information in multiple input's. They get saved, but the next time if the user comes. The inputs that are filled in, in the previous sessions will get filled in automaticly, but they still can get changed if the user wants.

Sorry I'm responding quite late, I'm multitasking
But I don't know how to actually upload the files
I try going to https://proxipi--proxneon.repl.co/upload_file but that doesn't exist
If worse comes to worse, I'll just make it use subprocess to download files
