yes, I'm talking about the /register route which aaccepts both GET and POST
#web-development
native tide
uncut spire
using something like flask_accepts
the flask.request object also has a method attribute, which will contain the relevant verb for a given request
native tide
Oh sorry maybe I expressed myself wrong
I meant, when I recieve a post request
I want to validate that there are no extra fields
and no wrong input on each form input
While having a React template
uncut spire
mmm why do you need to validate that there's nothing extra? just curious, like if i post you {'data': 'info', 'extra': 'foo'} is it that bad that i included extra?
you should validate the correct input using marshmallow and flask_accepts in my view, they are very easy to get started with
introduce a models.py specifying input and output let's say
native tide
Because (bad practice) curreently I just store the whole request on my db
first time working on web
uncut spire
ah
native tide
So when using postman, I realized how bad that is
uncut spire
yes not a great way to keep your sanity, but let's cover what you need
if you want to move on to using flask_accepts and swagger and api documentation/things of that ilk, post again and i'll help if i can
uncut spire
np
native tide
so for marshmallow and flask_accepts (the plural one, not flas_accept, right?) it's a case of either, or?
Or are they used together?
uncut spire
they can be used together, or individually
typically, people use flask_accepts alongside flask_restx for autodocumenting APIs (though fastapi is looking better and better)
example:
# myproj/models.py
from marshmallow import fields, Schema
class RequestBody(Schema):
my_field = fields.String(required=True)
another_field = fields.String()
class ResponseBody(Schema):
some_string = fields.String(required=True)
# myproj/app.py
from flask import Flask
from flask_accepts import accepts, responds
from flask_restx import Resource
from myproj.models import RequestBody, ResponseBody
app = Flask(__name__)
@app.route('/foo', methods=['GET', 'POST'])
class Foo(Resource):
@accepts(schema=RequestBody, api=app)
@responds(schema=ResponseBody, api=app)
def get(self):
pass # your logic here
def post(self):
pass # your logic here
and yes it's flask_accept_s_
but note the article i sent earlier, it outlines a way to do very vanilla flask with marshmallow doing the validation against a request.form or request.json

I am using regex to check passwords users input, I am not sure what Is wrong with this syntax
if not re.search('[A-Z]', password) or not re.search('[a-z]', password) or not re.search('[0-9]', password):
anyone have an idea why I get the error
expected string or bytes-like object
topaz widget
@hallow jacinth Why are you checking users' password inputs? Frameworks should have this covered.
Also, which web framework are you using?
hallow jacinth
flask, and framework doesn't cover it, I can enter passwords like "test" and it accepts it
topaz widget
Well, first of all, you can combine all those regexes into a single one.
'[A-Za-z0-9]' will cover all those.
That doesn't really solve your problem, but it will make your code way more compact and readable.
hallow jacinth
oh cool, didn't kno I could compact it like that
topaz widget
yeah
I think the problem is with your password variable. For some reason it isn't the right data type.
hallow jacinth
yeah I just thought of that
topaz widget
It's not really possible to see what's wrong from what you posted.
topaz widget
It's probably an attribute of the PasswordField object.
maybe .value
That's what it would be in JavaScript.
hallow jacinth
yeah I am going to look at documentation to see if it is a specific value
topaz widget
If the PasswordField is an object, it's probably an attribute of that.
Make sure it escapes the characters, though, because someone might be able to run code if you don't escape the user input.
Flask might do that automatically, but it's good to make sure. Django escapes automatically.

Does anybody have an idea to how I can check that password and confirm_password are equal?
Within the class, not the view...

Is this Django? @native tide

Yes @topaz widget
topaz widget
The default process should check that automatically
native tide
Which process?

The built-in registration view
native tide
Yeah but I'm building my own form from scratch.

I am writing a Rest API in Flask and noticed the request and response payload for some of the endpointsappearing in swagger do not tally with the namespace and resources in the controller
my user_account controller
details = CustomerDetailsResponse.api
cust = NewCustomerDto.api
_user = NewCustomerDto.user_account
_userdetails = CustomerDetailsResponse.userdetails
@cust.route('/')
class UserList(Resource):
@details.doc('list_of_registered_users')
@details.marshal_with(_userdetails, as_list=True, envelope='data')
def get(self):
"""List all registered users"""
return get_all_users()
#@cust.response(201, 'User successfully created.')
@cust.doc('create a new user')
@cust.expect(_user, validate=True)
def post(self):
"""Creates a new User """
data = request.json
return save_new_user(data=data)
my data transfer object
class CustomerDetailsResponse:
api = Namespace('userdetails', description='Response object when fetching customer details')
userdetails = api.model('user', {
'first_name': fields.String(description='user first name'),
'last_name': fields.String(description='user last name'),
'membership_id': fields.String(description='membership id of the user'),
'occupation': fields.String(description = 'occupation of user'),
'mobile_number': fields.String(description = 'phone number of custmer'),
'email': fields.String(description='user email address'),
'enabled': fields.Boolean()
})
class NewCustomerDto:
api = Namespace('user', description='Registers new customer')
user_account = api.model('user', {
'first_name': fields.String(required=True, description='user first name'),
'last_name': fields.String(required=True, description='user last name'),
'username': fields.String(required=True, description='username'),
'occupation': fields.String(description = 'occupation of user'),
'mobile_number': fields.String(required = True, description = 'phone number of custmer'),
'email': fields.String(required=True, description='user email address'),
'password': fields.String(required=True, description='user password'),
})
when I run in terminal I get this in swagger documentation -
Also my namespace -
from flask_restplus import Api
from flask import Blueprint
from .main.controller.user_controller import cust as customer
from .main.controller.user_controller import dea as deactivate
from .main.controller.lease_controller import emp as employee

)
register = Blueprint('dea', __name__)
dea = Api(register)
lease = Blueprint('emp', __name__)
emp = Api(lease)
validate = Blueprint('auth', __name__)
api = Api(validate)
cust.add_namespace(customer, path='/user')
cust.add_namespace(deactivate, path='/user')
cust.add_namespace(employee, path='/employee')

I am coming from a C# background, so I have limited experience writing APIs in Python (Flask). How can I resolve this?

posted doesn't exist
the latter is the ultimate cause of your problem

Sorry that I wasted your time

for posts in posts is doubly confusing because you use a plural term "posts" for a single post, and because the element and the collection are called the same thing

Out of curiosity which db language do you guys prefer with flask? I've read you shouldn't get into too much of sql lite if you're more serious about db in the future

You guys recommend flask over django for first time web development? as a middleman between databases and front end. Plan to have an admin page eventually
versed python
both have their places, django puts some rules in place so you have a consistent project structure that just works. Flask is generally easy to learn. At the end of the day, go with what suits you, not what people think you should use.
plucky tapir
I spent a good amount of today doing things in flask, but maybe I should give the other a shot as well. django seems to have a lot of features I'd probably have to really dive into to learn for flask, idk how much more time consuming it'd be to implement database/security/admin features

It’s looking like the django way is to categorize everything in their own apps within the project. I’m trying to figure out the purpose, This would help with more features later on and organization?
a register and login page considered under the main app?
twilit dagger
Yes in a users app @plucky tapir
plucky tapir
Ah yes thanks
It seems like there’s be main, users, then one for like info on your site.
Like articles if you had a blog site
A few like that, seems right? Or does it get broken down into a lot more apps
twilit dagger
Usually I've seen a home/whatever is the main on your site, and stuff like about and contact goes in there too, then a Users app and then stuff like shop, forums, etc.
So actually I've mostly seen only 2 apps for most websites

One option to go from userinput to db, I could create an html form, post the input to a model and migrate it to a database?
twilit dagger
Django provides you a default CreateView for making models @plucky tapir
You don't have to make a form
Django gives you a lot of things from the get-go
swift sky
any experience with ListWidget from wtforms
plucky tapir
@twilit dagger CreateView would still need a template right? Would it sortof be a substitute for the html? Would it much more convenient in the long run to use modelform rather than html?
twilit dagger
All you need to put in a CreateView template is {{ form.as_p }} @plucky tapir
Or better is to use Crispy Forms, then it's just {{ form|crispy }} and it looks much better
That's it
It makes the form and creates the model for you, you just have to make a submit button
It's far far more convenient to use the Views Django gives you, though in certain cases you still have to use ModelForms, no point in using base html forms.
Django gives you CreateView, DeleteView, ListView, DetailView, UpdateView etc. It also gives you LoginView and LogoutView
plucky tapir
Using the views from django, push/pulling info to/from the database will be significantly more convenient?
feels like django has the ability to make it mainly a python project

My issue is I have a partner who doesn’t know python but is doing the css/html and dB side of things. Django feels like it removes their contributions from the project
Although thinking of finished product in a short time it seems like django is the way to go.
topaz widget
@plucky tapir They need to learn Django's templating language, and you should be handling database stuff since most of that is taken care of by Django's ORM.
They should probably also "git gud" with JavaScript if they're going to be taking on the front-end part of it.
Django's templating language is not that hard to learn if that's all you need to learn.
@plucky tapir Your division of labor doesn't make a lot of sense. Usually isn't front-end and back-end. Having someone doing HTML/CSS AND database while you work with the back-end framework is not a great division of labor.
You should be handling the database.

How can I capture whenever a POST request is sent to my rest api in django
Because I want to do something whenever that happens so how do I detect it as soon as it does happen
plucky tapir
@topaz widget Thank you got it. So if I continue with django, there are still a lot of areas that html/css could still give a good amount of labor? If so what type of stuff would that be, I had the idea that using views almost removed html use.
topaz widget
You can't really remove the HTML use. Views in Django use HTML templates to render the pages. Your partner would just design the pages, and they could either learn Django's templating syntax, or you could just modify the HTML pages to add the templating syntax. It's probably better if they learn the syntax, though, since you will have parent and child templates, and someone will be doing a lot of extra work if the Django templating language isn't just used from the start.
@mortal shale Every request will have a method. If the request's method is POST, then do something in the view that handles that.
mortal shale
heres my current views.py
class HeroViewSet(viewsets.ModelViewSet):
queryset = Hero.objects.all().order_by('name')
serializer_class = HeroSerializer
is there a request type arg?
@topaz widget
topaz widget
There is a request object that would be handled by a view. This request object will have the HTTP request method (POST in this case) as an attribute.
Yes, it would be an argument to a view, as well, to answer your question further.
mortal shale
so I can put it in my HeroViewSet class as an argument or?
topaz widget
I'm not sure. I don't really know what the ModelViewSet class does.

Hi, I'm trying to generate a database with MySQL and MAMP. I installed sqlAlchemy to generate a data table but it didn't work. I am having this problem and already installed the libraries mysql flask-sqlalchemy, etc with terminal and python libraries.
Don't know what else I can do.

Having issues here
plucky tapir
@topaz widget I'm going to try to convert an html template to a django template to see the difference. Django would remove the need of creating/modifying databases because views handles it directly correct?
topaz widget
I'm not sure I follow what you're saying in either of those sentences.
@plucky tapir Not sure what you're saying. It's hard to render web pages with Django without making it a "Django template".
As for the database, Django models handle all the database stuff. You need to configure your database in settings.py, if you don't want to use the default sqlite database, but that's pretty much it.

Yo - I'm using flask and having a weird issue where a route creates a form which immediately procs "submit"
native tide
@swift sky yeah I have some experience with wtforms, whats up?
marsh swan
This has the rest of the code too
the issue is i want to dynamically be able to add scores on a page - so i have two forms
one is the base, which contains just scores and a submit button, and the other specifies the scores through a fieldlist of formfields
class PowerGridScore(FlaskForm):
scores = FieldList(FormField(PowerGridForm), max_entries=6)
submit = SubmitField('Submit')
Therefore for the route I have to do something like
scoreformname = game.gname.replace(' ','')+'Score'
baseformname = game.gname.replace(' ','')+'Form'
current_mod = sys.modules[__name__]
score_form = getattr(current_mod, scoreformname)
base_form = getattr(current_mod, baseformname)
class LocalForm(score_form):pass
LocalForm.scores = FieldList(FormField(base_form), min_entries=int(entries), max_entries=6)
form = LocalForm()
if i check submission of the form with form.validate_on_submit(), it IMMEDIATELY procs
the only workaround I've seen is just if request.method == 'POST': instead of if form.submit(): or even if form.validate_on_submit():
if i use validate, even though the field list is called with proper validators (datarequired() ) it will never actually validate
if I use submit, it never displays the page to begin with and just immediately redirects me
why does that newly created form immediately get submitted?
is there a better way to do this instead of checking if POST? i feel like that exposes me to just malicious code that could be interpreted but idk if wtforms handles that
class PowerGridForm(FlaskForm):
player = StringField('Player', validators=[DataRequired()])
plants = StringField('Plants', validators=[DataRequired()])
money = StringField('Money', validators=[DataRequired()])
that's the other form getting fieldlist'ed

@topaz widget I already have html files that would submit input, I would send that to a database using flask. Today I was going to try to convert the html into django templates to see what it is like. but I don't really see any examples online (to see a side by side comparison.)
topaz widget
It's probably somewhat similar to Flask. I think Flask uses Jinja, which is not that different from Django.
@plucky tapir If you have a bunch of HTML templates that are written in Jinja and it will be a lot of work to change them, you can also specify in your project's settings.py file that you want to use a different templating engine than the Django default. I have not done this, so I do not know the details. It is possible, though.
marble carbon
well you can use jinja as templating engine in Django as well
but Django template language is not much different from Jinja anyway so won't be much of a hassle converting them

@topaz widget fun fact, jinja2 was created based on django templating engine and the same creator made a fork of it for php

@zealous cloud 2020-09-26T00:00:33.084755+00:00 app[web.1]: ModuleNotFoundError: No module named 'keys'
zealous cloud
@vestal hound Oh shoot thats my api key. I put it into a separate file and put that into my git ignore. Is there a way to include it into the project without hard coding it in obviously?
zealous cloud
venv/
__pycache__/
.DS_store
keys.py
.vscode
huh
why is it in your .gitignore
that's what I'm asking
like
your server files won't be visible
to outsiders
it's fine to put it there
zealous cloud
oh because its my api key. It was my understanding that you dont want that in your project files?
vestal hound
hm
not if your code is public
but if you're only pushing to Heroku
(i.e. not hosting on a public GitHub repo or something)
it's fine
because ultimately
you need to have some sort of credentials in your server code, right?
otherwise how will you authenticate
zealous cloud
so push to heroku master with the api key but not to github correct?
correct. hadnt considered that. thank you. I didnt include it because I also have a github repo for it and thought somehow id be publishing the api key in my code'
vestal hound
so push to heroku master with the api key but not to github correct?
@zealous cloud yup!
correct. hadnt considered that. thank you. I didnt include it because I also have a github repo for it and thought somehow id be publishing the api key in my code'
@zealous cloud yeah, that's a good thought
it's great that you're considering the security implications
another way to do it is with an environment variable
I would suggest not using a .py file
some data file might be better?
like a JSON
or .env
even a .txt is fine
zealous cloud
that makes more sense now that you mention it. Thank you again. I'll look into a way to do that after I get it up and running.
vestal hound
yw!
urban wyvern
I'd put it as an environment variable and then load it in with os.getenv("NAME_OF_VAR")
Rather than keeping the code in a file at all
vestal hound
Rather than keeping the code in a file at all
@urban wyvern why?
urban wyvern
Avoid the potential of accidentally publishing it anywhere
vestal hound
they can leak (depending on the deployment environment)
marble carbon
there's a package called python decouple for that
heroku has config vars in project settings, which are equivalent to environment variables
zealous cloud
I used environment variables for my database and secret key. Not sure why I didn't think of doing it with my api keys also. BTW my project opened successfully

ok @cosmic nebula
cosmic nebula
Use FlexBox API
rotund token
i loaded my style.css in static folder but the images dont show up on my site
@solemn igloo make sure youlinkthem properly and have the right names and tags
how
cosmic nebula
/* style.css */
.container {
float: right;
display: flex;
flex-direction: column;
}
did u see my github
cosmic nebula
Or you can remove float and make the position: absolute; and then adjust/set the right to some viewport width
did u see my github
@rotund token no where is the link
cosmic nebula
Can you tell me where your code is? I'm on mobile rn and it's kinda hard to go through your code
Like the file and the line number
rotund token
wdym
cosmic nebula
Or your can tell me the class'name
In CSS
Like .container or whatever you named it
rotund token
ok let me find it
cosmic nebula
You can share a line by clicking on the line number and then clicking on the three dots and share
cosmic nebula
And it's children?
rotund token
.contact
cosmic nebula
Ok found it
rotund token
wdym
cosmic nebula
Like contacts
rotund token
ur confusing me
cosmic nebula
Or does it have a parent?
A parent container?
Which should hold all the contacts as a stack
rotund token
yeh there is 2 lables
cosmic nebula
Make a different container class for contacts
cosmic nebula
Cause of you change the main container class, all elements having that parent class will behave like a stack
No no
rotund token
<div class="contact">
<form action="#">
<label for="email">
Email: <input type="email" id="email" placeholder="Enter your email">
</label>
<label for="messages">
Message: <textarea id="message">Message</textarea>
</label>
<input type="submit" valid="Send Message" id="submit-button">
</form>
</div>```Ohkay
Then just add ```css
display: flex;
flex-direction: column;
And lemme know if it works
rotund token
hold on
cosmic nebula
Also I think this is how you use a label
<label for="email">Email: </label>
<input type="email" id="email" />
Use divs to cover all the label+inputs
rotund token
i have ill commit and push so u can see
cosmic nebula
You just have to postion the submit button a bit below
Yea
Add a .submit class for the submit button and style it
And then change its top value to a larger value
Or you can change the bottom value too
cosmic nebula
<input type="submit" class="submit" />
rotund token
div class='submit-button-wrapper'
cosmic nebula
.submit {
/* Style it, like color or background-color, etc. */
bottom: /* some value */%; /* or even vw works instead of % */
}
like margin
cosmic nebula
Yea that works too
rotund token
so
cosmic nebula
margin-bottom
rotund token
.submit-button-wrapper{
margin-bottom :
/* STYLE BUTTON */
}```how would i get the links to go lower as i did margin-top N it didn't go lower
@cosmic nebula
rotund token
that
cosmic nebula
Try postion: absolute; top: 95vh;
You can change the value 95 until it looks good
Remember it shouldn't be greater than 100 cause that will put the elements below the viewport

Are there any Python things I can use for front-end alongside HTML and CSS? No browser supports Python, yes, but are there are any things I can compile from Python to JS, either manually or not? Brython compiled it very incorrectly.

@marsh fog yes but also
GET requests should be idempotent i.e. if you submit them multiple times it shouldn’t be a problem
which is usually not the case for POST requests
e.g. imagine you use a GET to place an order
if you send it multiple times, you get multiple orders
which is not right
so usually GET requests are used for read-only stuff

I can view the debug panel when in the inspector view. This confirms that the template is loading, and injecting into my webpage. But none of the buttons work due to this error
I'm getting a 200 status when django is serving the js file as well.
Adding the javascript import directly in my own template fixes the issue:
but this isn't a resolution to the original problem.
Any idea what may be going on here?
The bug must have appeared 4 months ago due to this commit where 'type="module"' was changed.

I am creating a booking system. Seller signs up and they choose what days they want to work. i will then create a calendar and then only show the days the seller wants to work. So lets say I sign up, and I say I want to work Days: Monday, Wednesday, Sunday. I need to then add these days to the DB and then on the front-end only show them days in the calendar. How would you setup the DB table? I am thinking something like this:
class WorkerAvailability(db.Model):
__tablename__ = 'worker_availability'
id = db.Column(db.Integer, primary_key=True)
monday = db.Column(db.Boolean, nullable=True)
tuesday = db.Column(db.Boolean, nullable=True)
wednesday = db.Column(db.Boolean, nullable=True)
thursday = db.Column(db.Boolean, nullable=True)
friday = db.Column(db.Boolean, nullable=True)
saturday = db.Column(db.Boolean, nullable=True)
sunday = db.Column(db.Boolean, nullable=True)

Depends on how fast your services start.

Sometimes, you can spend thousands of dollars on engineering to save a few hundred on deployment costs, and end up with a more complex system, so make sure you calculate the costs properly first lol

how do you guys feel about sanic for building a frontend? i was comparing it to django, and it seems better because it has async functionality built-in from the get-go

does scraping count as web dev? @ me if u answer
swift crystal
let me try
resultset has no attribute text
i am using findall...
hmm
should i iterate through them?
south linden
yea
swift crystal
what even is it idk how to make it into a list or iterate it
is it a list or a string idk
more details:
low blade
why do you keep screenshotting an impossible to read image at this point instead of just copying the text itself?
copying the text would probably make it easier for people to read, and therefore help you
swift crystal
ok
so originally I needed to extract the text from some html code i scraped
I got how to do that but I cant do it to a resultset
I need to iterate over it to do it to each one
but i have no idea how.
ok

Hey i have a question about Django + Bootstrap can anyone help?
distant trout
flask-restful vs fastAPI, someone know which one is better overall?
low blade
this is a summary @terse viper provided in #career-advice
my quick summary of benefits are:
- it's an API framework, so specialized for API work. Flask is a bit more general-purpose. An obvious example of where specialized for API is good is the error messages re json by default
- unified query, path, and body inputs as arguments. Flask uses the request singleton for stuff, and it's inconsistent. Having arguments is neater (functions more pure)
- built-in run-time schema validation and static checking with pydantic. Flask has no such thing. This also uses python type hinting
- built-in automatic documentation generation. you will literally get a /doc page with swagger UI generated for you automatically if you define your input/output models with pydantic
- async support
- websockets
- graphql

hey everyone, need some help with something. i had this flask program that was running fine before, but now it keeps giving me a flask.cli.noappexception
devout coral
Anyone know what the best practice for having something done on a schedule or a regular basis in Django is? For example I want to go through all my records in a model and if they are certain days old I want to delete them.
cerulean vapor
@devout coral that kind of thing is best done with a script that you run by way of the operating system's task scheduler.
devout coral
Well my initial thought was to run a cron job to directly interface with my SQL database but then I thought implementing it into the Django site might be best.
cerulean vapor
you can run a cron job to launch a script that uses Django's ORM
that's the way I'd do it myself
teal glacier
theres a library called schedule that is very easy to use. im not sure its a 'best practice' though
cerulean vapor
for something that only happens once a day or something like that, use cron.
devout coral
Yeah, which is what I thought of doing but lets say I deploy this at a different location and now i'd have to set that up and add seperate documentation for it. I thought adding it to the app would be best. Guess not.
cerulean vapor
cross that bridge when you come to it :D
use what works now to get it working now.
devout coral
Haha ok.
cerulean vapor
just make a note that it has to be ported.
devout coral
Yep, I can add that to the doc no big deal. Just thought it might piss some people off that there is also this separate thing that needs to be used.
cerulean vapor
As long as it's documented, it should be fine
devout coral
Then from cron I should be able to use the Django ORM if anyone is using different SQLs?
cerulean vapor
ideally. I believe Django ORM is pretty abstract
devout coral
Ok, I also saw some people mentioning celery but I have never used it. Any thoughts on that?
cerulean vapor
I haven't used it myself
brave gyro
I dont know if this is the write chat sorry but I want to make an app using react native that basically allows me to take a picture of something at store it in a map like google maps would i have to use the google cloud api?
devout coral
So you normally just set up a management command and then run it through cron?
cerulean vapor
@devout coral or a script that imports the needed components to be Django-aware
@brave gyro you'd have to use Google's APIs to interact with anything Google.
devout coral
Ok, I think I am going to go for a management command so I do not have too many outside dependancies
and this way if something happens I could also easily run it manually
cerulean vapor
that makes sense
devout coral
Cool, I appreciate your help.
cerulean vapor

class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)

validators=[validate_image_file_extension])

def save(self, *args, **kwargs):
username = self.user.username
self.slug = slugify(username)
super().save(*args, **kwargs)
This is my model
Was wondering how do I list all the followers of a profile in an APIView?
class FollowerModelSerializer(ModelSerializer):
user = CharField(source='slug')
class Meta:
model = Profile
fields = ['user', 'followers']
This is the serializer.
class FollowerModelViewSet(ModelViewSet):
queryset = Profile.objects.all()
serializer_class = FollowerModelSerializer
allowed_methods = ('GET', 'HEAD', 'OPTIONS')
def list(self, request, *args, **kwargs):
self.queryset = self.queryset.filter(id=request.user.id)
return super(FollowerModelViewSet, self).list(request, *args, **kwargs)
And this is the API
All it returns to me is the id of followers in the API View instead of all the followers.
Allow: GET, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept
[
{
"user": "pop",
"followers": [
1,
4
]
}
]```
This is the response I get.Basically, I want to get the username in there instead of the user id.

vestal hound
JavaScript
you basically want a dynamic webpage
you could do this with Flask but it’d be inefficient and complex IMO
mortal geyser
You will basically have an empty array and a js function that each time you call it, it will push that required ingredient to the array
so when u use "add more" button you will call that js function instead of performing a server call

Hey guys Im using django , I have a Model that i added a custom function to, when i get a queryset i need to sum all of monthly_totals
class CustomerTransaction(models.Model):
customer_transaction_id = models.CharField(unique=True, max_length=255, blank=True, null=True)
customer_agreement_id = models.ForeignKey('CustomerAgreement', on_delete=models.CASCADE, null=True, blank=True)

meter_number = models.CharField(max_length=255, blank=True, null=True)
def monthly_total_kw(self):
today = datetime.date.today()
total = 0
if self.transaction_date.month == today.month and self.transaction_date.year == today.year:
items = self.customertransactionitem_set.filter(units__isnull=False)
for item in items:
total = total + Decimal(item.units)
return total
i would like to be something like this,but it wouldn't work because its not a column in the table but rather a function...is there another way i could do this without having to loop through each item and add them together?

@hollow root if it's a function, you most likely can't directly query it, as it is pure python
an option is adding computed fields and store in the db, and then you can directly query it
does anyone have experience serving a django page as an actual url instead of localhost?
@vestal estuary as a url, just means hosting it somewhere else, pointing your dns at it, and wiola (of course, not the whole story)
ngrok is a nice alternative
or geting an aws ec2 instance for example and just hosting it there
look up computer networking basics and you'll begin to understand the process
but what you're basically looking for is, "deploying the app"
google deploying a django app, and im sure you'll find some great sources on how to do it
@hollow root actually now that i think of it, you don't really have complex logic in that function, look into query expressions more specifically, F queries - a django thing
and rewrite it as a pure query

I have this Crispy Form in Django, I want there to be some space between the fields and for the last 2 fields to take up the entire row
In the template I just have ```
<fieldset>
<legend><h1>Get a Quote From Us:</h1></legend>
{% crispy form %}
</fieldset>
Forms.py - ```
class ContactForm(forms.Form):
first_name = forms.CharField(required=True)
last_name = forms.CharField(required=True)
contact_email = forms.EmailField(required=True)
phone_number = forms.CharField()
company_name = forms.CharField()
additional_comments = forms.CharField()
helper = FormHelper()
helper.layout = Layout(
Row('first_name', 'last_name'),
Row('contact_email', 'phone_number'),
Row('company_name'),
Row('additional_comments'),
)
helper.form_tag = False
field = forms.CharField(
widget = forms.Textarea(attrs={
'padding-right': '10px'
})
)
I think you can do something like this @twilit dagger
else, you need to split the form and use columns and rows (that is if you use a css framework)

Notsure if this is the right place for my questions, if not, im sorry.
but anyone here with experience with flask?
Trying to make a "bank"-app as a project, and I was thinking that every user that makes an account would get a "randomized encrypted URL", so that i can prevent people from just typing in other users in the URL and getting there bank account up.
Im new btw. So little experience 😦
native tide
you should probably look into flask_login @lean rapids
because a url can be brute forced, but flask_login uses sessions to allow you to restrict acess to urls based on the users status
