@opal fulcrum You should probably know a bit of HTML before jumping into Django, but you can learn both at the same time.
vestal hound
there are only 2 possibilities:
- your token is broken (meaning the source is bad)
- the library is buggy (doubt it)
topaz widget
@opal fulcrum If you want to build a nice website, you should know HTML, CSS, JS, and backend language and framework like Python/Django.
versed python
html is very easy to learn but as the other guy said difficult to master
opal fulcrum
@topaz widget ohh so it's a long learning curve i see
topaz widget
Yes, most definitely.
versed python
so you can easily learn django, and html parallelly
opal fulcrum
why did you say backend language and framework like django ... i thought django is backend
is there is something different between a framework and backend o.O
versed python
@topaz widget ohh so it's a long learning curve i see
@opal fulcrum just wait till you hear about django rest framework then
versed python
that backend handles logic for you
topaz widget
@versed python lol I haven't been masochistic enough to jump into that yet
vestal hound
DRF is pretty nice
I'm using it right now
I gotta say
building a RESTful API is hard
topaz widget
I started getting into it but backed off.
versed python
frontend is basically used to make pretty looking stuff
vestal hound
it's quite a different way of thinking
topaz widget
for the time being.
versed python
it's quite a different way of thinking
@vestal hound yeh it is
topaz widget
it's quite a different way of thinking
@vestal hound Yeah, exactly.
vestal hound
and recently I've been restructuring a lot of my API to be RESTful
the uniformity is nice
opal fulcrum
i know this is a weird question but how long as average can learn all django - HTML - CSS- js
vestal hound
but some operations are very difficult to express
versed python
and then I just discovered that the market is slowly shifting towards Graphql instead of Restapi
topaz widget
@vestal hound I was going to make a single-page application with DRF and Vue, but it was just too much when I tried to jump into it.
vestal hound
yeah, that's basically what I'm doing now for my startup
planning to launch in a couple of months
versed python
@vestal hound I was going to make a single-page application with DRF and Vue, but it was just too much when I tried to jump into it.
@topaz widget this is basically what I am doing rn
topaz widget
Can you say what the business model is?
understand if you want to keep downlow, though.
vestal hound
Can you say what the business model is?
@topaz widget what do you mean?
topaz widget
@versed python Then you're a little ahead of me on that front.
vestal hound
and then I just discovered that the market is slowly shifting towards Graphql instead of Restapi
@versed python GraphQL shares similarities with real REST
topaz widget
What is the business of your startup? (Understand if you don't want to say here)
versed python
i know this is a weird question but how long as average can learn all django - HTML - CSS- js
@opal fulcrum I'd say around 8 months brought me to where I am,since I started as an absolute beginner
opal fulcrum
@versed python you learned all that in 8 months wow
vestal hound
when you say "business model" I was thinking you meant like marketing strategy and stuff
opal fulcrum
i thought that would take me idk 3 years or something
vestal hound
3 years is a long time
versed python
no 3 years is a lot
topaz widget
@vestal hound No I meant what the business is about.
opal fulcrum
so an average 1 year is very good to learn all that
versed python
yeah but just the absolute basics of web development
vestal hound
private tutors are very common
so like an application to streamline the interaction between students and tutors
versed python
@opal fulcrum you will then have to dive into a frontend framework
topaz widget
Gotcha
vestal hound
incidentally, IMO
topaz widget
@versed python What front-end framework are you using?
vestal hound
the big frameworks are better
versed python
vuejs
opal fulcrum
so your 8 month was only for backend ?
vestal hound
like I'm using Angular/Django (with DRF) and it feels like if I had done React/Flask instead
topaz widget
Yeah, I like Vue best from what I've seen so far.
versed python
@opal fulcrum and very little frontend yeah
versed python
React is way too difficult for my brain to grasp
topaz widget
@vestal hound I heard Angular is kind of showing its age. Have you experienced this?
versed python
vue has the gentlest learning curve
topaz widget
You can definitely ease into Vue
vestal hound
@vestal hound I heard Angular is kind of showing its age. Have you experienced this?
@topaz widget I don't have the context or knowledge necessary to give the best answer
versed python
especially since it can be used directly in django templates
vestal hound
but I personally find it quite easy to use and I have not encountered any problems on the coding side?
topaz widget
hm ok
vestal hound
however, I must say that I am getting beaten up by the CSS
opal fulcrum
thanks guys i will be following this Corey guy tutorials for django .. can you recommend me a way to learn HTML as well ?
vestal hound
mostly because everything I've been learning is ad-hoc
though that's not exactly an Angular problem
versed python
@opal fulcrum Interneting is Hard is a very good website
vestal hound
I really like Observables
topaz widget
I've used Vue instead of Django tempaltes in places.
versed python
I've used Vue instead of Django tempaltes in places.
@topaz widget as of now my frontend and backed are completely separated, I'm not even using vanilla django anymore. switched to drf
topaz widget
ah
vestal hound
yeah, vanilla Django is the one that is showing its age, I think
topaz widget
So you're using Vuex and VueRouter then?
versed python
idk, django is pretty good to me
versed python
So you're using Vuex and VueRouter then?
@topaz widget i use a framework called nuxt built on top of vue, and they have nuxt router instead of vie router. so yeah that and vuex pretty much
vestal hound
I hear it's not as good as SQLAlchemy, but so far it does almost everything I need
there are some intermediate SQL things that I can't do in Django
but they're not hard necessities right now
topaz widget
Why nuxt instead of VueRouter?
versed python
yeah i dont even know sql that well, I still didn't find any need to learn it
Why nuxt instead of VueRouter?
@topaz widget look at nuxtjs.org this stuff is better explained there
topaz widget
Okay. How about authentication? How do you handle that?
topaz widget
Yeah, seemed like that was the hardest part.
topaz widget
I actually thought Vuex would have played a role in maintaining sessions. Is that the case or no? @versed python
topaz widget
lol
topaz widget
You might have some problems with that later tbh.
versed python
nah this is how I learn, just stumble through until I suddenly understand everything one day
topaz widget
I just mean not knowing how something works means you may not be using it quite right.
I do the same thing, though. Not judging.
versed python
well this strategy has worked out for me, so I'll be sticking with it
but I get what you mean though
topaz widget
Just a comment, not really a criticism.
versed python
yeah i understand
zinc hill
Hey its me again, I have 2 models customer and company. each company and customer has a onetoone realationship with User.
I am trying to do a profile pages for both. is there away for me to do @login_required(are u a customer or company)
topaz widget
kind of, yes.
zinc hill
each model have this is_customer = models.BooleanField(default=True)
topaz widget
but login has to do with the user model, not the other model.
topaz widget
You need to modify the user model if you want to set the user to a company or a customer.
and create a field for whether it's a company or a customer.
zinc hill
ok gotcha ahhhhh I just got this to work now I have to play with model again
Thanks man
topaz widget
Yeah, you need to subclass the default user model.
no problem
There are other ways to do it, but that's probably the best way.
vestal hound
Hey its me again, I have 2 models customer and company. each company and customer has a onetoone realationship with User.
I am trying to do a profile pages for both. is there away for me to do
@login_required(are u a customer or company)
@zinc hill what do you want to happen if the user is logged in but neither a customer nor a company?
topaz widget
lol i was thinking the same thing for admins
zinc hill
hmm I dont think they can logged in as that
topaz widget
Well, an admin will probably need to log in and be neither.
topaz widget
You can still accomplish that with subclassing.
zinc hill
maybe i will make something for admin as well
topaz widget
You can just set blank=True for the customer/company field, which will let it be blank.
then you just need to program the logic for that condition.
topaz widget
I assume he(?) wants a different page to display depending on whether the user is a company or a customer.
zinc hill
yeah
vestal hound
no, I mean
zinc hill
and im very very new
vestal hound
why a one to one relationship?
okay, how about you talk about what you wanna do
from a wider perspective?
topaz widget
Because he was using it wrong.
zinc hill
ok so the project is basically like ubereat
topaz widget
?
zinc hill
you have company and customer and driver
topaz widget
oh
vestal hound
so you have different types of users
zinc hill
yeah
topaz widget
Uber Eats
vestal hound
how about an integer field with user type?
topaz widget
yeah, but that's subclassing the user, right?
vestal hound
nope
just a field
alternatively
Django has groups built in
you can use those too
topaz widget
hm
vestal hound
yeah, but that's subclassing the user, right?
@topaz widget unless you mean the built in class
then yes
zinc hill
i was messing around with those and it got complicating
this is why i was using the 1to1
topaz widget
@vestal hound I think we mean the same thing. Subclassing the default user model.
or extending, yes.
vestal hound
yeah
I did that from the start so it didn’t occur to me
i was messing around with those and it got complicating
@zinc hill is this your first Python project?
it might be good for you to do some research on SQL and how it models relationships between real-world objects
you don’t need to know how to write complicated queries, but you should at least understand how one would model common relationships
because otherwise you’ll be fighting the ORM and probably losing
topaz widget
fighting the ORM and probably losing
XD
vestal hound
ok i will into that stuff
@zinc hill btw is English your first language?
zinc hill
nope
vestal hound
okay just curious

for index, _ in enumerate(range(100), 1):
with tempfile.NamedTemporaryFile('rb', suffix='.jpg') as file:
PostImage.objects.create(
post=random.choice(posts_list),
image=ImageFile(file) # from django.core.files.images import ImageFile
)
print('Image file created')
This is a django management command snippet that I am using to generate some data for my database
everything works as expected- (empty) image is being created, and being uploaded too.
But since tempfile.NamedTemporaryFile() opens a file /tmp/temporaryname.jpg, the images are uploaded to my webserver with the name tmp/temporaryname.jpg and hence an extra useless directory called tmp is being created in my MEDIA_ROOT
How can I prevent this?
# what I want

# what is being created

- tmp/

product_img_original_name = db.Column(db.String(100), nullable=False)
product_img = db.Column(db.String(200), nullable=True)
Since the user can create a product, I thought it was best to store all the images in one table, including the profile image. Or should I move profile image into the Profile table? What do you think?
of any other way I should setup these tables?
lethal orbit
Ufff
Maybe make a an Abstract Image model, and derive ProfilePicture, ProductImage, etc. from it?
past cipher
never heard of abstract model, I will look it up
versed python
I think that’s how django save files, but i might be wrong
@jagged lark so there's nothing I can do?
jagged lark
I’m not sure, but I think
past cipher
@lethal orbit can you give a quick explanation as to what Abstract is? I don't seem to understand it
lethal orbit
@past cipher first two questions is why you use __tablename__ and why you add an id .... Using the defaults should be fine in 99% of cases (as Django does give pk and id properties by default).
An Abstract model is essentially a mixin that lets you reuse code.
past cipher
because I'm using Flask
lethal orbit
OH!
past cipher
and class name shouldn't be pural
where as table name should
so thats why i use tablename
past cipher
yep
I just don't understand Abstract, I can't find a solid tutorial/walkthrough online
lethal orbit
I havent worked with SQLAlchemy.... but normally, you would declare an Image mixin, with information about the file itself.
past cipher
but why would I use abstract, when I am going to create a table called Images anyway
lethal orbit
Then derive models from that.
class Image(db.Model):
__tablename__ = 'images'
id = db.Column(db.Integer, primary_key=True)
user_id = db.Column(db.String(100), nullable=False)
product_id = db.Column(db.String(200), nullable=True)
profile_img = db.Column(db.String(200), nullable=True)
product_img_original_name = db.Column(db.String(100), nullable=False)
product_img = db.Column(db.String(200), nullable=True)
Single-responsibility principle.
Why do you have a profile_img and product_img together?
How is a product tied to a user?
lethal orbit
class Image(db.Model):
img = db.Column(db.String(200), nullable=False)
class ProfileImage(Image):
# inherits the `img` field from the Image class
user_id = db.Column(db.String(100), nullable=False)
class ProductImage(Image):
# also inheerits `img`
product_id = db.Column(db.String(200), False)
Then you can add as many product images as you want... and your models are independent.
Not sure how you would make an abstract model in SQLAlchemy though, as I don't work with it.
But having the product and profile images in the same model is a code smell.
past cipher
but from your code above, isn't that just creating multiple tables
I'm new to SQL. I thought having all images in one table was best
lethal orbit
Nah...
It just adds extra complexity, tbh.
You definitely shouldn't mix them in the same row.
You could have a img_type column in your table, so you can have an image row that is a profile_image, and another that is a product_image...
But mixins are the cleanest way.
Also, more tables means smaller tables, so if you need to query all profile pictures, you can do it more efficiently.
select * from profile_images; <-- selects from a smaller set
select * from images where profile_img != null; <-- selects a larger set, and has to do an extra filtering operation.
vestal hound
I'm new to SQL. I thought having all images in one table was best
@past cipher if you definitely have one image of each kind per user, then yes.
but I'm guessing that each user definitely has one profile image?
if so, that should probably be on the main user model.
however, each product has its own image, and multiple products can belong to one user, right?
that's called a one-to-many relationship
and suggests that products should be in their own table
one row per product
and they can be linked back to their owning user with a user_id column
lethal orbit
You should also allow multiple images per product, IMO
solar ridge
How could I pass a value from the class based create view (overloaded) __init__ to the form __init__ ?
Right now my classbased create view is creating the form with form_class = MyCustomForm
vestal hound
You should also allow multiple images per product, IMO
@lethal orbit that would depend on their business logic
but yes, that's definitely a possibility
and would require a third table

Can you elaborate on your question
swift sky
so most people have told me that serving content like pdfs is best done by allocating space on your server
and placing the content there
and in your code, pointing to that location which contains the content
what is confusing me, is how one is supposed to build out their website
and simultaneously have it point to the media content
since they are developing locally in their IDE and only then pushing it to cloud after.

So I am getting data from an api and trying to export it to excel, but my to_excel function only uses the result of my most recent get_page function...
I might have to hit someone up on fiverr for help on this, but I thought that I would try here out first. I have problem with my function. I want to be able to use the result of my first fuction in my new function multiple times, but I keep overwriting the file I want to create. Does this sound like a difficult fix?

Hi, if your function only returns last page maybe you need to implement for loop and iterate? and save each step?

@maiden kraken Is this comment directed to my code?
maiden kraken
@last sable yes, but I am beginner in python so you dont have to listen to me 🙂
versed python
(hint: listen to @maiden kraken)

It sounds like you know more than me!

of course you have to worry about overwriting your file, ideally you want to 'append' not save over

So im trying to make my bot add a reaction to the message the bot sends but i can only ever get it to send emojis by themselves, not as reactions
@true python umm its web development channel
go to #discord-bots
maiden kraken
well... I would first debug this, try what your function returns. If it returns specific page (last) and you have multiple pages then you need to iterate through it
last sable
It returns the most recent API call (i.e. get_data())
maiden kraken
something is strange here, you write you want to use your first function inside another, but you are not using it at all?
last sable
I am using the response object created by the most recent function
maiden kraken
you maybe meant this responseName = getpage(url)?
sorry I think that's beyond my skills right now

Hey, I'm having some issues with pytest & flask-login
When I run my test, I can login my user, but after I make a request with the test client (client.get('/someurl')), current_user reverts back to the AnonymousUser within the same context manager 🤔
Snipped test in here: https://pastebin.com/Q8tQWVcF
I've seen examples that use the test client to post a form in order to login, but I dont think I can do that; my site authenticates against Azure AD with msal; hence forcing a login with flask_login.login_user in the test. I did have an if statement in my authentication route to check the current app config for 'testing' flag which just passed through the auth without hitting msal, but that seems like pretty poor security practice to me

@burnt night well, if you didn't have a backend, where would the requests go?

i just meant if they had to be attached like with flask etc
or if they could be separate

what do you mean "attached"?
okay I'm not sure if this is the best place to ask since it's more deployment than development, but...anyone ever got a 502 from a deployed Django app on GCP, but logs are empty?

Does anyone know if there is a method to paginate items that aren't being stored in a database or are part of a model? Im using this route below to make an api call and then passing the response object directly to my jinja template and creating bootstrap cards for each item in the response object. This data updates daily so I dont want to save it in a db. I have about 100 cards on the page, so it'd be nice to be able to paginate this info into 20 per page. Everything I've seen however seems to show pagination with queried items. My flask route is below
@app.route('/search/member/<member_id>')
def get_member_info(member_id):
"""Retrieve individual government official data on link click"""
res_object = []
offset = 0
while offset <= 60:
res = requests.get(
f"{MEMBER_VOTE_POSITION_API}{member_id}/votes.json?offset={offset}", headers={'X-API-Key': key})
data = res.json()
res_object.append(data)
offset += 20
members_data = res_object
# page = request.args.get(get_page_parameter(), type=int, default=1)
# page = request.args.get('page', 0, type=int)
# page_size = 20
return render_template('search/officials_voting.html',
members_data=members_data,
member_id=member_id
)
And my jinja template where I'm creating the cards for each item.
{% for record in members_data %}
{% for item in record['results'][0]['votes'] %}
<div class="row justify-content-center mt-3">
<div class="card bg-white w-75 my-4">
<div class="card-header font-weight-bold">
<a href="/search/bill/{{item['bill']['bill_id']}}">{{item['bill']['bill_id']}}</a>
</div>
<div class="card-body bg-info">
<h5 class="card-title">Bill info - <span class="text-primary">{{item['bill']['title']}}</span></h5>
<p class="card-text"><strong>Vote description: </strong>{{item['description']}}</p>
<p class="card-text"><strong>Date of vote: </strong>{{item['date']}}</p>
<p class="card-text"><strong>Vote result: </strong>{{item['result']}}</p>
<p class="card-text"><strong>Latest action: </strong>{{item['bill']['latest_action']}}</p>
<p class="card-text"><strong>Voting position: </strong><strong><u>{{item['position']}}</u></strong></p>

Hi I wanted to scrape some Google maps for testing purpose, unlike static pages I believe google map has a wrapper of some sort. Because if I manually type the whole link with page=2 on the address bar it's going to the next page, however when my scrapper pases the link it just reads the same page again. I am using beautiful soup only for this. Please ping me if you know the solution

Hi guys, im making the django tutorial part 3 using psql as my database, i just wrote that view, and http://localhost:8000/polls/ shows just a 404, the console show no error, what am i missing here?
@solemn igloo why did you name ur functionindex?
name the function get which translates to GET request view
and
as_view is a method
it missed the ()
versed python
^
solemn igloo
@marsh canyon so, just rename the function and ad the "()" to the as_view function.
like that?
marsh canyon
aand
ur get method is a method inside the calss
class*
so u need the self param too in the starting
or you can convert ur method into a staticmethod by adding @staticmethod decorator
@solemn igloo
also, using render() will be cleaner imo instead of HttpResponse
versed python
I suppose since they are following the official docs, the render method hasn't been introduced uptil tutorial 3
so they will learn it soon enough

oh okay 👍

A lot of us do, you can just ask your question right away, no need to ask to ask

i ask because nobody answers my questions 🙂 . So, i have this urls.py that contains multple apps with different views. I m trying to call those views like that:
path('', cos.views.home, name="HOME")
but I get an Attribute error that my module has no views.
zealous moth
create a view
zealous moth
create a function inside it
native tide
i don t understand :))
# this is the home function
def home(req):
products = Product.objects.all()
return render(req, 'cos/home.html', {'products': products})
what function are you talking about
zealous moth
did u import views in urls
native tide
yes
or not
i did it like that
import cos
import noutati
because i have multiple apps
if i do
from cos import views
it will not see the views from the another app
zealous moth
try creating urls for app and call from there
native tide
how do i do that
native tide
hmm i guess i will use one app to do all the things
i only need one path
from that another app
create urls.py inside app
@zealous moth sure bud but how do i import it in the main urls

like the admin urls is imported
url(r'^',include('appname.urls',namespace='given_namespace'))
you can search in google

not working

AttributeError: module 'noutati' has no attribute 'urls'

it is using regex expression but for path() i dont know how to call urls

and my urls.py:
from django.urls import path

@wanton ridge Did you try flex-direction:column?
wanton ridge
@twilit dagger yes didnt work
twilit dagger
Maybe you're doing it on the wrong element
It should be the parent element of both pic and text

yes i did it too but no

And the Profile model handles pfp and bios and stuff

Hey guys i have a problem ☹ as you see my output photo i can create model but i cant use auth.user’s values. I want to create external values but for example i want to use into auth.user name , last_name, last_login values..
class student(models.Model):
authority = models.ForeignKey(Group,on_delete=models.CASCADE,verbose_name="Yetki Tipi")
avatar = models.ImageField(upload_to = 'media/profile_image', blank=True,verbose_name="Fotoğraf")
name = models.CharField(default='',max_length = 50,verbose_name = "Adı")
surname = models.CharField(default='',max_length = 50,verbose_name = "Soyadı")
birthday = models.DateField(blank=True, null=True,verbose_name = "Doğum Tarihi")
email = models.EmailField(default='',verbose_name = "E-Posta")
phone = models.CharField(default=0,max_length=11,verbose_name = "Telefon Numarası")
parent_phone = models.CharField(default=0,max_length=11,verbose_name = "Veli Telefon Numarası")
gender_choice = (
('Erkek', 'Erkek'),
('Kadın', 'Kadın'),)
gender = models.CharField(max_length = 30,blank=True, null=True,choices = gender_choice,verbose_name = "Cinsiyet")
created_date = models.DateTimeField(auto_now_add=True,verbose_name="Kayıt Tarihi")
def __str__(self):
return self.name ```You haven't added a models.ForeignKey to User, and also don't store the users last_name etc in this Student model. That's why youy can't access these properties.
@tacit comet
Two ways to solve this:
- add
first_name = models.CharField()etc toStudent. I don't recommend this method.
- Add a
user = models.ForeignKey('auth.User', on_delete=models.CASCADE, related_name='user')to yourStudentmodel.
Then you can access these attributes via Student.objects.get(pk=1).user.first_name etc. Like that.

twilit dagger
Sort of strange but my hover classes don't work in Heroku
quick cargo
@twilit dagger you sure heroku is actually serving the css file if you have a seperate file for that
quick cargo
@twilit dagger whats the full class list?
twilit dagger
This is all -
.navbar-nav .heading{
color: white;
}
.navbar-nav .heading:hover{
color: #444444;
}
.navbar-nav .header-btn:hover{
color: #333333!important;
}
.header-btn:hover{
color: #333333!important;
}
"btn btn-outline-light float-right text-light header-btn btn-lg"
I sent CSS so it makes sense
This is with bootstrap
quick cargo
you know you havent defined the base css for it first right?
cant apply a hover varient to a css element that doesnt exist 🙃
twilit dagger
what are you saying
quick cargo
everything todo with the button you have as hover varients
twilit dagger
<div class = "text-right float-right">
<a href = "{% url 'contact' %}"type = "button" class = "btn btn-outline-light float-right text-light header-btn btn-lg">
Contact</a>
</div>
Doesn't bootstrap handle that
quick cargo
no idea
twilit dagger
it works on localhost just not on heroku
twilit dagger
whitenoise
quick cargo
does any of the css work
quick cargo
that is a yikes tbh
i dont know heroku so i cant really help you with much more of that im afraid
So im looking for some feedback on a router im making and wondering if others might find it useful.
The general idea is to make it easier for you to layout your applications with fewer global varibles using true class instance views regardless of the framework.
Example of a view file:
# ./views/my_view.py
import router
from sanic import Sanic
from sanic.websocket import WebSocketConnection
from sanic import response
from sanic.request import Request
class MyEndpoint(router.Blueprint):
def __init__(self, web_app: Sanic):
self.app = web_app
@router.websocket("/")
async def my_func(self, ws: WebSocketConnection):
pass
@router.endpoint("/hello")
async def hello(self, request: Request):
return response.text("Hello world")
def setup(web_app):
web_app.add_blueprint(MyEndpoint(web_app))
Example main.py
# ./main.py
import typing as t
from sanic import Sanic
from sanic.websocket import WebSocketProtocol
from router import Router, Endpoint, Websocket
app_files = [
"views.my_view"
]
app = Sanic(__name__)
def submit_route(_, endpoint: t.Union[Endpoint, Websocket]):
if isinstance(endpoint, Endpoint):
app.add_route(handler=endpoint, uri=endpoint.route, methods=endpoint.methods)
elif isinstance(endpoint, Websocket):
app.add_websocket_route(handler=endpoint, uri=endpoint.route)
router = Router(app, app_files, submit_route)
if __name__ == '__main__':
app.run("127.0.0.1", port=8000, protocol=WebSocketProtocol)
In this example im using Sanic but this will work with any ASGI or WSGI framework, using a simple callback for you to tailer your route setting to the framework's design.
This should help anyone stuggling with laying out their apps with lots of global varibles gain a bit more control over their layout.
Please let me know of any feedback you have for this and if you think it would be useful to make public 🙂

Hello there
So I have an SSO login at my office...I can direct to it and get the key and refresh key back...how does flask separate that info from the next person loggint in 5 seconds later?
fleet sorrel
can someone help me convert python script to exe file
warped timber
flask is easy and lightweight
plucky tapir
Nice thank you though. I wasn't aware of this I always thought they were created though html/css or javascript
zealous siren
Vue and either Flask or FastAPI
fleet sorrel
is it possible to do front end in django or flask?
zealous siren
Yes but it’s not industry standard
versed python
uggh that's why I hate the industry
why can't it just accept vanilla django
now I am having to learn all this Javascript shit
zealous siren
Because More responsive
versed python
ik the reason why it's industry standard. doesn't mean i like it
zealous siren
Sure but there is damn good reason for it
versed python
i know it. I'm using Vuejs now, and can see how websites look better right out of the box
I guess it's kinda a tradeoff. You either choose beauty with more time spent or, ugliness but with less time spent

hi
just trying to add a filter
for all the different atributtes from a model
and all the atributtes have different kind of values
some are boolean, some are charfield, some are intFields
etc
so every filter has to be unique
and I don't know how to join them
if someone has a clue or an example to share
:c
versed python
@valid sandal django or flask? Share your model structure here please.

Looks like this is what you want https://docs.djangoproject.com/en/3.1/topics/db/queries/#complex-lookups-with-q-objects

it does not run all of the code for each request
it does run a bit to check if there is a request
but the actual request handling happens once

guys who is better change something in admin panel or in database?
tawdry magnet
heres the answer your going to hate
"it depends"
if your going to be doing it a lot maybe its easier to do it in the admin panal
lethal orbit
guys who is better change something in admin panel or in database?
@mystic wyvern If you mean Django, the admin panel should not be used by too many users. It's meant specifically for administrators, not end-users.
tawdry magnet
if its going to be rare and only you know how to do it then maybe its not worth the effort and u can just do it in the database
lethal orbit
If you mean a one-time change to your models, nothing wrong with using admin
mystic wyvern

hi everybody 😊,
my english is bad so please be kind.
i use python since 1 month, my background in web development 5 month in php.
i win a stage and the begin of diffuclt is here ! my brain 🧠 have no connexion with the unit-test ( pytest)
perhaps some of you have a good hints or tips to helps me ! i need a success small one but one 😊😊😊
thanks
ps: i work with the framework piramid ! python3
lethal orbit
perhaps some of you have a good hints or tips to helps me ! i need a success small one but one 😊😊😊
I find using functional programming paradigms makes writing unit tests easier. Don't try to keep too much logic tied to your data models, but write logic in small, easily testable functions as much as possible. As a bonus, you can easily reuse those functions across different modules and models.
Also, check out #unit-testing , and read as much as you can about the topic. I recommend these 2 books, even though they are not related to pyramid in any way:
- https://pragprog.com/titles/bopytest/python-testing-with-pytest/
- https://www.obeythetestinggoat.com/ (free to read online, but I am not a fan of selenium).

'function' object has no attribute 'objects'???
high jacinth
Help pls, if I have an app that does something that takes like ten seconds to work hosted on heroku, does that mean each user who sends my app a request has to wait ten seconds or do they join a queue and have to wait for ten seconds*the number of users ahead of them? Or does it simply crash?
Sorry if the question doesn't make sense
versed python
Probably the first especially if your app has a lot of good looking stuff
An easy way to check is by trying to access the website through your pc, laptop and a few phones from your family members @high jacinth
high jacinth
@IgnisDa I'll do just that actually
lethal orbit
oof
What are you doing that takes 10 seconds @high jacinth ? Why not pre-calculate it?
jagged lark
No, doff
high jacinth
@lethal orbit I'm webscraping and wrapping the result up in an epub. I also wanted to know how heroku would deal with blocking code if there was any
jagged lark
Maybe you should cache your result then
Of you aren't using any *wgi system, they will just end up on a queue, yeah
lethal orbit
If it is one file, you are probably better off indexing it.
high jacinth
I'm not scraping the same thing repeatedly. What's *wgi??
lethal orbit
If you are letting people pass a URL, then it is definitely more complicated.
If it is a set of epubs, you probably also would want to process them all and index them.
jagged lark
They are tools made to dispatch the requests to many instance of your server
high jacinth
@lethal orbit I'm not keeping any epubs, I just want to consume the url then spit out an epub
@jagged lark pls give me hint
And by that I mean direction to documentation. Do I just google wgi?
jagged lark
I'm not sure if that's possible with heroku
high jacinth
Oh. 😢
native tide
@lethal orbit thanks 😊
verbal obsidian
because fucntion object does not have attribute objects.
you are probably looking for a model object
and got something else
if we are talking about django of course
verbal obsidian
I could perhaps help you a bit more if you shared the snippet that triggered the error
mystic wyvern
look i write this in my views
def new_topic(request,boerd_id):
board=get_object_or_404(Board,pk=boerd_id)
if request.method =='POST':
mes =request.POST['message']
sub= request.POST['s']
user=User.objects.first()
Topic = topic.objects.create ( subject=sub,
created_by=user
)
the issue is with topic
are you importing it correctly?
and is it a class that inherits from models.Model?
mystic wyvern
yeh i do all of this
and i import it and i inherits from models.Model
look class topic(models.Model):
woeful swan
in drf how to pass a non model field of any type and get it back in response ?
woeful swan
i tried that but after .is_valid() call it is not present in the validated_data
marsh canyon
do you read-only set on those fields by any chance?
nvm
SerializerMethodField() is by default read only
marsh canyon
then
u can define fields in the serializer
custom fields
just outside ur Meta class
woeful swan
for now
class QuerySerializer(serializers.ModelSerializer):
# q = serializers.CharField(required=True, max_length=512)
extra_params = serializers.SerializerMethodField()
q = serializers.SerializerMethodField()
def validate_q(self, value):
return value
def get_extra_params(self, *args, **kwargs):
print(self.initial_data, 'extra params')
return self.initial_data.get('extra_params')
def get_q(self, *args, **kwargs):
return self.initial_data.get('q')
class Meta:
model = SessionInfo
fields = ('q', 'bot_id', 'session_id', 'extra_params')
# extra_kwargs = {
# 'bot_id': {'write_only': False},
# # 'q': {'write_onlyr: False},
# }
class QueryResponseSerializer(serializers.Serializer):
session_id = serializers.CharField()
response = serializers.ListField()
status = serializers.DictField(required=False)
extra_params = serializers.SerializerMethodField()
def get_extra_params(self, *args, **kwargs):
return self.initial_data.get('extra_params')
class QueryApiView(views.APIView):
def post(self, request, *args, **kwargs):
# print(request.data, 'berfoer')
## session validation
try:
session_obj = SessionInfo.objects.get(session_id=request.data.get('session_id'),
bot_id=request.data.get('bot_id'))
except SessionInfo.DoesNotExist:
return Response({'error': 'session does not exists for given bot'}, status.HTTP_404_NOT_FOUND)
# serializer with instance
serializer = QuerySerializer(instance=session_obj, data=request.data)
print(serializer.initial_data, 'initial')
# checking validation
if serializer.is_valid(raise_exception=True):
print(serializer.validated_data, 'validated')
# fetching response
resp = bot_response(serializer)
finalize_data = {
'session_id': serializer.validated_data.get('session_id'),
'response': resp,
'extra_params': serializer.initial_data.get('extra_params')
}
serializer_output = QueryResponseSerializer(data=finalize_data)
if serializer_output.is_valid():
serializer.save()
return Response(serializer_output.data, status.HTTP_200_OK)
return Response(serializer_output.errors, status.HTTP_400_BAD_REQUEST)
return Response(serializer.errors, status.HTTP_400_BAD_REQUEST)
using this
i just want the extraparams in request and return as it is while saving the data
marsh canyon
what are you passing in
woeful swan
i am very new to drf so it is confusing me?
{
"session_id": "SUq50ChnZjRiZ5rb",
"bot_id": "MGZI6EE3",
"q":"hiii",
"extra_params": {
"amit": "bisht"
}
}```ok
on more question. how can i accept any type of data . not just char from that field
?
marsh canyon
well you can use a charfield and take in whatever you want and later parse it
there is even Json field
and u can pass anything with the json
woeful swan
but it has to be string right?
marsh canyon
mostly, yes
woeful swan
i want it to accept int, list, dict and str
marsh canyon
its good have a data type assinged, to not confused the API user
then make 4 fields for those
woeful swan
well setting as charfield worked now. I don't know why it was not working before?
marsh canyon
u use SerializerMethodField() before, right?
woeful swan
then make 4 fields for those
@marsh canyon i mean extraparams can be of any of those type?
woeful swan
u use SerializerMethodField() before, right?
@marsh canyon no first i used charfield, but it was giving error so after researching i used SerializerMethodField but that was not coming in validated data.
marsh canyon
like path/?name=iceman
here name is a param and the value is iceman
you can get these by doing either request.GET or request.get_params -> these 2 are query dicts
woeful swan
no non no . extra_params is just a key name. it can be optional data. which api user can pass and will be returned same in response
{
"session_id": "SUq50ChnZjRiZ5rb",
"response": [
{
"sender": "SUq50ChnZjRiZ5rb",
"message": null
}
],
"extra_params": "amit"
}```response sample
marsh canyon
so maybe a dict will be good for extra params
woeful swan
yeah i have considered that
marsh canyon
or just have explict names for all the extra params
woeful swan
in dict field there is child argument
marsh canyon
i mean havea field for each extra param
woeful swan
what does it checks
i mean havea field for each extra param
@marsh canyon i understand
BTW thanks man for helping
marsh canyon
the child arg is to set the data type for values
the keys are assumed to be string
docs
marsh canyon
oki
woeful swan
👍 👍 👍
marsh canyon
lemme know how it goes, cuz i have never used DictField
woeful swan
sure. i am just now rewriting a single serializer for this. two are confusing me.
marsh canyon
oki
woeful swan
{
"session_id": "SUq50ChnZjRiZ5rb",
"bot_id": "MGZI6EE3",
"q":"hiii",
"extra_params": {
"amit": "bisht",
"roman": 34,
"texas": {
"smash": "yes"
}
}
}
{
"session_id": "SUq50ChnZjRiZ5rb",
"response": [
{
"sender": "SUq50ChnZjRiZ5rb",
"message": null
}
],
"extra_params": {
"amit": "bisht",
"roman": 34,
"texas": {
"smash": "yes"
}
}
}```
yeah it worked mancool 👍
marsh canyon
i guess the default is charField
oh nvm, if you dont provide one, then it will not bother checking
woeful swan
ok
marsh canyon
@zinc hill maybe post ur question down here again, just so its noticed
zinc hill
ok thanks
view.py
class RestaurantLoginView(LoginView):
template_name = 'accounts/restaurant/login.html'
def get_success_url(self):
url = 'company_profile'
return super().get_success_url()
how do i redirect to something else instead of LOGIN_REDIRECT_URL
marsh canyon
right
so instead of returning the Super() implementation, you can return url instead
lemme check what format the url is in
you have to set url to the full path
and not the url name
or you can import resolve_url from django.shortcuts and pass in the url name to resolve_url to generate the url for you
zinc hill
yeah I tried setting the url = 'company/profile/' and return url but it keep adding on to the path
marsh canyon
use resolve_url
zinc hill
ok I will look into that
marsh canyon
from django.shortcuts import resolve_url
return resolve_url(<your url name>)
this is how django does it internally
django uses resolve_url
this is the source code
zinc hill
Vs
marsh canyon
awesome
if you hold ctrl and hover over LoginView
it should be highlighted, when you click it, it will take u to the source code
zinc hill
yeah I saw that and I didnt think to replace the "settings.login_...." to something else
marsh canyon
settings.login.. is just the url name, if you remember
zinc hill
I was trying to think of something stupid like setting settings.login.... to something my url instead...
instead of just replacing that smh
marsh canyon
its fine, you know now
zinc hill
thanks alot
marsh canyon
👍
zinc hill
thats enoguh for today smh
marsh canyon
django does burn ur energy fast 😬
zinc hill
yep got stuck for so long today because I realised that I didnt need AbstractUser so I delete the database and makemigration, but it keep saying auth table doesnt exist
marsh canyon
u need to migrate
zinc hill
turns out one of the terminal was open and was in manage.py shell
yeah I did
once I quit the shell... and do the migration again than it work
marsh canyon
also, you need to reconfigure the auth model in settings
zinc hill
that was 2hrs of googling wasted
aaight thanks again for helping me out
have a great night
marsh canyon
u too
woeful swan
@marsh canyon you there
Got AttributeError when attempting to get a value for field extra_params on serializer InitSerializer.
The serializer field might be named incorrectly and not match any attribute or key on the SessionInfo instance.
Original exception text was: 'SessionInfo' object has no attribute 'extra_params'.
getting error. but model is saving data
in DRF
cold grove
Is there a way to exclude an attribute from being serialized by json.dump?
mystic wyvern
Cannot assign "<Board: 1>": "post.topic" must be a "topic" instance.
what this is?
dense slate
Is there a way to use something like:
rating_dict = sorted(rating_dict, key=rating_dict.get, reverse=True)
but for larger querysets? Especially when scaling. It's taking like 4-5 seconds so far for 500 entries.
I'm essentially needing to sort a user directory by rating, which is devised by a method on the user object that does some stuff to determine the rating.
I considered just having a rating field on the user, and updating it whenever the user does "something", but that makes it less accurate over time.
fair light
why do i get this error and how do i fix it? please ping me in reply
