you probably want include('polls.urls', namespace='polls')

royal musk

i tried this

#

but django gave me an error that it is not supported

do you still ahve the error around?

also try leaving the action attribute empty, thus the form still should work, since when you leave it by default the action will be set to the current page

Hi

#

I've my project with django postgres and redis, it's a chat application

#

I'm looking to scale it, anyone with experience of where they've deployed it?

#

I've my test on heroku, I've been trying to deploy production to AWS beanstalk and failing at it. If anyone has any guide, would be helpful, the one's on Google are outdated and doesn't seem to work and AWS docs was really bad

meager anchor
#

if you want to learn a bit, then just getting a regular VPS (like digitalocean droplet, hetzner server, netcup vps) to deploy on is probably the best way to go. as for scaling it, it depends what your current bottleneck is, i would assume the first place to look would be the django app?

barren pagoda
#

is there a tutorial on building APIs with django without DRF? everything seems to suggest DRF but i want a barebones look at it

meager anchor
#

that depends on what you want your API to do - the most basic API could just receive a request, decode it from json, lookup some data, and serialize & return that as json

#

then you’ll probably also want things such as token authorization, validation, etc.

#

for validation, you could use database constraints, …

barren pagoda
#

yeah i want to do all that

#

returning as json first of all

#

since that is not clear from the tutorials

#

btw quick question, what are the default names for html, cs, and js files? On the mdn docs I saw index.html, main.css and javascript.js

cinder sequoia
#

Heyy can anyone please help me re-create a cool looking eportfolio?

calm plume
#

Only index.html for HTML

#

And in nodejs, index.js is the most common entry point but that doesn't matter in the browser

native tide
#

Well I want to use seperate files for css and js

calm plume
#

But it's not a bad idea to go with index.js

calm plume
#

Why does the name matter to that?

native tide
#

so index.js and what do I call my css file?

native tide
calm plume
native tide
#

I've also seen script.js an style.css are those common names?

native tide
calm plume
#

Some call in main.css, some styles.css, others globals.css, all are fine

calm plume
native tide
#

oh so what I have rn is index.html, main.css and javascript.js is all good?

calm plume
#

Yeah, that's fine

#

Although I've never seen javascript.js before

native tide
calm plume
native tide
native tide
calm plume
#

Basically, you can name anything besides index.html whatever you want

native tide
#

Is there a reason for that? I've seen main.html one time

calm plume
#

index.html is the commonly accepted entrypoint. Most services will always view that as the base of your project. (e.g. the url would be example.com instead of example.com/otherstuff)

native tide
native tide
#

thank you

#

Oh yeah and another thing

calm plume
#

I don't know if there's reasoning behind naming it index.html, but that's what it is 🤷‍♂️

native tide
#

Is this formatting good?

# 

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title>test</title> 

        <!--Link to css file-->
        
        <link href="style.css" rel="stylesheet"/>

        <!--Link to javascript file-->

        <script src="script.js"></script>
#

Or are spaces bad

#

and comments no good for html

calm plume
#

That looks fine, but you probably don't need a space between the comment and the actual line

calm plume
#

The fact that you're importing a css file and a js file can be easily understood by glancing at the code

#

You don't need to specifically say that

native tide
#

Right makes sense I've just started html/css not too long ago so I usually like to comment so I don't forget

#

are the links suppose to be under the title or nah?

calm plume
#

There are all sorts of guides on the order, but no official guidelines or anything that really matter

native tide
#

so there's no documentation for formatting?

calm plume
#

I mean, not really

#

What would there be?

native tide
#

Idk, html looks hard to read when all the code is clumped together

calm plume
#

There's no official style guides afaik if that's what you mean

calm plume
#

I prefer pug because of that actually

native tide
#

Is that a markup language or smt

calm plume
calm plume
#

Basically an alternative syntax for html

native tide
#

oh that's cool. good to know

All webhook events have a common structure that includes information you will need to process and respond to the event, including the PSID of the sender and recipient of the event. In addition to the properties shown below, each event also has its own event-specific properties.

Note that entry is an array and may contain multiple objects, so ensure your code iterates over it to process all events. For a complete description of event properties, see Webhooks Reference.

It says here "Note that entry is an array and may contain multiple objects, so ensure your code iterates over it to process all events."

Anyone familiar with the Facebook Messenger Platform API? I wonder in what instance are there multiple events being delivered to a webhook?

``` As you can see I'm using an `ASYNC socket.io` server. I wanted to ask whether I am required to spin a thread to resolve the request on ASYNC socket.io because some requests might take some time (1s - 3s) to resolve and I don't wanna interrupt other requests that might happen while solving this request
#

Example: On connection my server needs to rebalance jobs for all the connected workers and it might take some time

I'm running the server using uvicorn like so: uvicorn server:app

#

should i use fastapi or django as backend? planning to use it with both react and react native and mysql as db

#

i asked this over at #software-architecture yesterday and was told to use fastapi instead, not sure if thats better or worse:

so im creating a project with django as backend and react as frontend, should i:
a) use django-admin startproject then create an app called frontend and manually add all the required stuff for react (since idk still how to npx create-react-app in a django app, it just doesnt work for me fsr)
b) use django-admin startproject then without creating an app, do npx create-react-app then somehow link django to it? im not sure how that would work
c) use npx create-react-app then somehow create a django project inside, not sure how that would work either

any help would be appreciated!

#

wdym?

#

ive followed some tutorials that uses django and react combinations and it works pretty well

thorn igloo
#

you know how django uses template rendering etc, that stuff is irrelevant when you use something like react. i don't know if i'm making sense here

lilac heart
#

ah i see what u mean

#

yea its kinda counter intuitive in a sense

#

but i thought some big companies like instagram uses django and react

thorn igloo
#

i mean you can use it but you'll be using django like an api mostly

lilac heart
#

i see

thorn igloo
#

same for any other backend framework really

lilac heart
#

yea i get it now

#

guess itd be the most intuitive if i just go and use fastapi

dusk portal
# 
class Order(models.Model):
    name=models.CharField(max_length=50)
    email=models.EmailField()
    author=models.OneToOneField(User,on_delete=models.CASCADE,unique=False)
    phone_no=models.IntegerField(default=0)
    address=models.CharField(max_length=100)
    zipcode=models.IntegerField(default=0)

    def __str__(self):
        return  self.name``` ```py
@login_required
def order(request):
    if request.method=='POST':
        name=request.POST.get('name')
        email=request.POST.get('email')
        author=request.user
        phone_no=request.POST.get('phone_no')
        address=request.POST.get('address')
        zipcode=request.POST.get('zipcode')
        print(author)
        entry1=Order(name=name,email=email,author=author,phone_no=phone_no,address=address,zipcode=zipcode)
        entry1.save()
        return HttpResponseRedirect('/')
    return render(request,'index/order.html')``` so the problem here is the 1st time when i  filled the form when logged in from account called "admin" it works then i again tried to fill same form when logged in with user called "admin" it throws error , then i filled form with user  "test" it works hence it shows user can fill form only 1 time how can i fix that error ```IntegrityError at /order/
UNIQUE constraint failed: index_order.author_id

django rest framework as backend services fine to react

lilac heart
#

trying to build something like a twitter/instagram clone

inland oak
#

instagram was built with django 😉

lilac heart
#

yea-

#

but thought its more intuitive if its fastapi

inland oak
#

the only issue with django you will have

#

partially limited async support

#

it works for views, and there are django channels for web sockets, that's ok mostly

lilac heart
#

yea thats the thing i found on google

inland oak
#

but Django ORM is sync at the moment

#

that's why Fast API can be preffered

#

since it has no in built ORM in it

#

you can setup from the start async friendly ORM

lilac heart
#

and django is slower compare to fastapi too

#

idk i think i might give fastapi a try

inland oak
#

there are so many ways to speed up web app

lilac heart
#

tahts true

inland oak
#

that at the end it will probably no matter which framework you used at the start

lilac heart
#

yea

#

i see

inland oak
#

the good things about django, that it brings really fast development at least

#

any feature is just plug and play

#

so it could make better end result just because you will have more time to use for development of architecture and optimization

lilac heart
#

ah

#

i mean, ig i could always try one out and if it doesnt fit i can just switch

inland oak
#

i hope they will eliminate their last weakness with ORM not async supported though

#

we can expect it around december to see perhaps

lilac heart
#

oooo

inland oak
#

it is scheduled for Django 4.0

lilac heart
#

damn

#

then itd be pretty perfect

inland oak
#

yeah

so im extremely new to web designing as in ive pretty much never done it but im trying to find if theres a way to read mouse coordinates through something like flask or django. I normally use tkinter which has the ability to track mouse coordinates, but I was considering trying a website but im struggling to find ways to track mouse movement. does anyone know a way to do this? if someone responds please @ me 🙂

thorn igloo
twin shore
thorn igloo
#

you're just using javascript to read the mouse co-ordinates, and sending them to the backend if that's what you want too do

i have a relatively simple (i think) issue that i'm not sure how to solve with django regarding models and subclassing a model

i have a Payment class (inheriting from models.Model) and i want to extend this into more subclasses, because each Payment has a payment_method type which is a string like 'creditcard', 'paypal', etc..

so i have created a CreditCard class which inherits from Payment and has fields like name, number, cvv and so on. and another PayPal class which has fields like email and so on.

what i want to achieve is something where, when someone is creating a new payment, when they specify the payment_method string, they also have to add the corresponding extra fields specific to that payment method -- e.g. they would have to include the number of the credit card if they choose 'credticard'

how do i go about this?

next comet
#

guys Is there any way i can clean a specific common field between let say 3-4 forms and to write a Mixin for it? and if so how can i do it

#

instead of copy pasting the same stuff in all forms

untold lava
#

to look details search: Django ForeignField

barren pagoda
#

thank you! i'll look for that

untold lava
#

Follow the tutorial of django there is an example in there.

mint folio
#

But is your question about how to collect the different info for different payment methods?

barren pagoda
#

i want something like when i hit /api/payments itll show me every payment and generic information (common to all) and then when i hit /api/payments/<id> itll show me all that payment's data including its specific parameters like number if it's a credit card

mint folio
#

Well in my example ID is needed as it the transaction tables makes reference to it from payable id.

barren pagoda
#

because i want one /api/payments endpoint with a POST on it where i'm expecting the given parameters depending on the payment_method the body has

mint folio
untold lava
mint folio
#

For your payment data collection just have some logic that show le the appropriate view for each payment method. For example, for card payment you will show the credit card form, and for PayPal you will redirect to PayPal

untold lava
#

I think you shouldn't create submodels which inherits base Payments model and just define payment_method string with data getting from a form page.

mint folio
#

Also for this certain design patterns can make this easy, and more maintainable so in the future it’s easier to add or remove payment methods without affecting other paths of the code.

Here's a typical payload when a user sends a message (Facebook Messenger Paltform API).

My webhook receives this POST request however, let's say we've asked the user to provide some text input.

How would we generally setup something that:

  1. Catches that it's the same user in order to respond to the same user
  2. Wait for their text input

open your command prompt and type python to switch python shell

then type these line-by-line

#

check your python path

# 
import sys
print(sys.path)
#

because there is something wrong in your modules path

#

like /Library/Frameworks/Python.framework, it should have been like python/Lib/site-packages/... but not...

if you change your packages path you should set this folder's path to your PATH or PYTHONPATH environments.

I've heard that socket in used in creating a chat app, so if you are a python backend programmer and you're told to make one(an API that does that) to send to the front-end, how do one go about it?

#

quick help
extra_kwargs = {"email": {"required": False}}
how do I write if I have an additional field "speciality" that I also want to set to false?

elder pier
#

Channels takes away the need to figure out a bunch of socket stuff as well as Django’s auth and session system

#

It’s pretty cool

#

But if you really want to learn how to use the WebSocket API then I believe Mozilla has a few articles that might interest you

@wet mortar check the network analysis tab of your browser, do you get 404 for the static pages? does pythonanywhere host the static files?

What are you doing on the template?

dusk portal
#

it's for ecommerce site and i used author here so every user can see thier order history before a day i was doing from OneToOneField so it was working but was not taking more then 1product from same user

#

so i got to know about this field

#

Manytomany

wet mortar
mint folio
#

Many to many would be wrong for that case

#

A user has many orders

dusk portal
#

so Manyonmany should work ig

mint folio
#

Many to many would be if an order can belong to multiple users

eternal blade
jade lark
#

there is nothing wrong with using a many to many here. It depends on how he wants to represent the relationships.

#

for example he would use a onetomany

dusk portal
#

ohh

jade lark
#

and then use object_set but that depends on the use case

dusk portal
#

what should i use here how u guyz indentify what to use when and where

#

wow

eternal blade
#

You will be using ManyToManyField when creating a custom user profile etc...

dusk portal
#

ohh

#

wait lemme do that

mint folio
eternal blade
dusk portal
#

when to use Manytomany when to use onetomany when to use foreignkey

#

damn

jade lark
#

To build upon that if you want all orders for a user (to render in a template or view) you would then use ```
orders = User.order_set.all()

dusk portal
#

i have idea of OnetoOne

eternal blade
#

ManyToManyField will be using in creating a like button etc...

jade lark
#

Using a foreign key as stated above is a OneToMany

Morning ppl, I wanna ask something about validators. I have an ImageField, and I'm wondering is it enough the built in validator in the actual ImageField, or should I use the django- validate_image_file_extension

also what do you consider a good max image file size (like 1 MB 2mb ?)

native tide

i guess the more resolution more pixels and higher file size ?

I had a quick DRF question of my own.

class Resource(models.Model):
    uri = models.URLField(primary_key=True)

class ResourceSerializer(serializers.ModelSerializer):
    class Meta:
        model = models.Resource
        fields = ('uri',)

class ResourceViewSet(viewsets.ReadOnlyModelViewSet):
    queryset = models.Resource.objects.all()
    serializer_class = serializers.ResourceSerializer

router = DefaultRouter()
router.register('resource', views.ResourceViewSet)
....

See above for a sample view, model, serializer and router config.

Imagine you have a resource like Resource(uri="https:/example.com/foo.bar")

How would I view its details.?
/api/resource/[what goes here]

Normally a primary key goes there. But since my PK itself is a URL how does it work?

I have for example tried something like /api/resource/https%3A%2F%2Fwww.example.org%2Ffiles%2F9999%2F9999.zip with no success

#

These are the RE printed by the DEBUG config

api/ ^resource\.(?P<format>[a-z0-9]+)/?$ [name='resource-list']
api/ ^resource/(?P<pk>[^/.]+)/$ [name='resource-detail']

I have tried encoding . with %2E with no success as well.

olive tiger
#

your resource still has an id

#

because the model creates a table with id and url columns

#

you can also specify url instead of pk in your urls or use lookup_field to change that behaviour

#

but I would not do it

heady ore
#

There is no id column in my APP_NAME_Resource table

#

I just checked.

#

That is due to primary_key=True i assume.

olive tiger
#

just call any record from the db and check its id

#

I do not know what you are using for this, but there is an id field

#

id column is created by default

#

oh, primary key - yes

#

that is correct

#

I have not noticed it

#

why do you do it?

heady ore
#

it makes sense to me URI is unique.

olive tiger
#

just use the default, do not overcomplicate things

#

just make it unique

#

unique=True

heady ore
#

sure i can not make uri primary. But what is the solution for this? Are string primary keys just not possible in DRF

#

i don't know what i'm doing wrong, since other string primary keys work fine.

olive tiger
#

maybe possible but what is the point for that?

heady ore
#

just URI's don't work.

olive tiger
#

uri's have some special characters, which may break something

#

I would not do it any way

heady ore
#

well there's no explicit point. String PKs are usually equally fast as integer PKs and in this case i wouldn't have to make a separate column and users could identify the resource with the URI

#

why have id and a URI?

olive tiger
#

also it will significantly decrease the performance

olive tiger
#

imagine how your urls will look https://my-domain.com/https://sfghskjhg/sdlfsldkfj?slkdjf=lskdjflsj

#

😆

heady ore
#

but that makes sense no?
I have viewing a detail for that particular URI.
So to me it is much better than https://my-domain.com/some_opaque_id
There is virtually no performance difference between integer and string primary keys for my use case.

olive tiger
#

the slashes brake it

#

I would not do it any way

let me try asking

elder nebula
#

What's the most practical way in django to check if data matches data in database. I've been using

try:
    if Model.objects.get(date__iso_week_day=selected_weekday):
      # Logic
except: ObjectDoesNotExist:
    # Logic```
#

is that the most effective & practical way?

glacial perch
olive tiger
elder nebula
#

ohhh

#

thx

olive tiger
#

actually, with if also works

elder nebula
#

yeah, I've been using the if in my projects. Don't know if it's bad

olive tiger
#

filter looks cleaner to me

olive tiger
elder nebula
#

get gets you the item, filter just filters the queryset I think

#

suitable for my case

olive tiger
#

yes, but you do not need those constructions with try-except

elder nebula
#

true

olive tiger
#

also for get you need to check for multiple values: try: except: except: becomes bigger

elder nebula
#

yes, otherwise error occurs

#

but if you make the field unique, you don't

olive tiger
#

depends on your search criteria

elder nebula
#

true

olive tiger
#

but, yes, searching on a unique filed should work

elder nebula
#

It's true that the try gets bigger and that's where need to start thinking other options

olive tiger
#

I know, some people overwrite the default get, with including the try except

#

but filter looks simpler solution

#

and get anyway uses filter 😉

elder nebula
#

it does?

olive tiger
#

yes, you can check the source

#

so, get looks somewhat redundant

elder nebula
#

it returns result_cache

#

ohh it uses filter but on it self

olive tiger
#

but it uses filter to get the value, if I am not mistaken

elder nebula
#

clone = self._chain() if self.query.combinator else self.filter(*args, **kwargs)

#

so filter is as fast as get?

#

because if application needs to check 1000s of records, it needs to be fast

olive tiger
#

I was never interested in knowing it

elder nebula
#

Would be cool to discuss it with someone who has had app with large amount of records / production

olive tiger
#

probably, the difference is not that big

elder nebula
#

yeah

olive tiger
#

also try-except adds up to the time

elder nebula
#

The most important thing is that the time stays relatively close to same

olive tiger
#

looks the same to me

elder nebula
#

yeah, if it doesn't take seconds to get the data to the page, it's fine

olive tiger
#

in my experience those large apis had much bigger problems with performance than comparing get and filter 😆

elder nebula
#

I might do a test app which I load with lots of database records and test different methods

elder nebula
olive tiger
#

yes

elder nebula
#

get only gets one

#

it was nice discussing with you

#

A bit of newbie here to web development , but would flask be a good starting point to start learning web dev?

olive tiger
#

personally, I find django better for this

native tide
#

what benefits do you think django has over flask ?

supple bramble
#

Django is much larger than flask and has a amazing orm, it provides really useful things like User model, Admin site, Authentication system, Security etc. Django is better suited for large scaled application while Flask is great for smaller projects, now you may ask why not use django for smaller projects? Well you surely can but that would be way too complicated, with flask you can create a simple API with like 5 lines, with django you would need settings.py, urls.py, asgi.py, wsgi.py, your actual app and stuff which is too overkill for a smaller project

#

Imo it really depends on what you wanna do, neither Django or Flask are too hard atleast to start with. Personally I would say django because i'm a bit biased towards it 😅

native tide
#

Thanks for that , great information . But for someone who is a complete beginner (I have no projects set at the moment) , would you still recommend me learning django

#

in future I would want do larger projects , so I guess im answering my own question . Go for django

supple bramble
#

yeah, in case it gets confusing then you can try flask

#

Corey Schafer on YouTube has a really great Django series (he also has a great Flask series), highly recommend it. Other than that, Django documentation is also very well written

native tide
#

Didnt know Corey the goat had a series on Django , that sounds super

supple bramble
#

haha yeah

native tide
#

just want to play devils advocate here but doesnt netflix and reddit use flask ? maybe im not understanding your point , but you can still use flask for larger projects its just harder ?

meager anchor
#

nothing stops you from using flask on a larger project, or django on a smaller, but I agree with @supple bramble that django eases working on big applications very very much. i think at the scale of netflix / reddit you can just throw your 500 developer team on it and it doesn't really matter much which framework they're using

native tide
#

yeah thats fair , thanks

#

# native tide what benefits do you think django has over flask ?

personally, I think, the django's complexity is its strong point, also for a beginner. Flask is built in such a way, that it only has a small number of functionalities and you need to search and integrate into your project the ones, which are missing, i.e. almost everyhting. Then you may have some trouble to make them all working together. Django has the most of the things included and setup. So you just start a project with 2 commands and it has all the things you need already structured for you in a convenient way (there was a comment about creating all those, but they are created for you automagically). i see more advantages than disadvantages - all the components are there, you learn to properly structure your project, you learn about the flow request-response, easy db integration, great orm, authn/authz, pagination, serialisation via DRF etc. etc.

eternal blade
#

Yeah

#

The main problem with Django is it's complexity for beginners

#

If you are not that familiar with python even the official Django tutorial can get a little confusing

permission_classes = [permissions.IsAuthenticated]
serializer_class = PostSerializer
queryset = Post.objects.all()```

#

this is the urls ```py
urlpatterns = [
path('search/', PostListDetailfilter.as_view(), name='postsearch'),
path('', PostList.as_view(), name='listcreate'),
path('posts/str:slug/', PostDetail.as_view(), name='detailcreate'),

path('create-post/', CreatePost.as_view(), name='createpost')

]

#

and this is the function in my react component ```jsx

afterSubmit = () => {
console.log(this.state.data);

axiosInstance
  .post(apiURL + "create-post/", {
    title: this.state.data.title,
    author: this.props.users.filter(
      (user) => user.username == localStorage.getItem("currentUser")
    )[0].id,
    excerpt: this.state.data.excerpt,
    content: this.state.data.content,
  })
  .then((res) => {
    this.props.history.replace("/");
    console.log("foo");
  });

};``` This is the method that runs when I click the submit button.

I have a flask app which runs fine from pycharm but when I try to run it with the same venv from the command line, it can't find the stuff it's supposed to import

#

does anyone have any idea why that might be?

#

What the difference between nav and header in use case

calm plume
#

Header is specifically the top part of the page

mystic wyvern
#

How it can be in nav

calm plume
#

It just means navigation

scarlet kiln
#

quite the opposite navs can be in the footer

calm plume
#

for example on this website, the footer is a bunch of links to navigate to various pages

Pasting large amounts of code

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

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

still nothing

#

i've been trying for an hour now

not sure what the problem is

#

"not allowed to load local resource"

#

lol

opaque rivet
#

oh, just realized you're trying to reposition:

<input type="text" name="test" id="button1">

To access IDs you have to use #, thank @versed python for that

#button1 {
    position: relative;
    bottom: 30;
}
opaque rivet
# native tide

btw, this looks like the request to submit your form, not the request to retrieve the .css file.

native tide
#

oh...

#

this is without the path

#

when i pass in path it says unable to retrieve local resource

scarlet kiln
#

I am experiencing an issue where I can run a flask app in pycharm

but it doesn't work from the command line

#

I think because pycharm adds the project source to PYTHONPATH

has anyone experienced this issue?

calm plume
#

From my understanding, that's a browser security feature that's stops you from using paths that resolve to your local computer rather than a specific url

Is it really worth it to integrate ReactJS with Django (not DRF)? Why do people even want to do that? Are there any benefits or something?

#

Imo templates are really good and easier to work with and get everything done, and afaik there isn't really any good reason to use React with Django, but I might be wrong so can someone maybe clear this out?

speed is the only thing then right?

inland oak
#

Speed... And what is available in terms of js animations

supple bramble
#

you can use js in templates too tho

inland oak
#

You can have literally a game paying in js for client

supple bramble
#

No one is stopping you from using js in html templates right

inland oak
#

But with react... You just use arrays of js libraries. More set of ready to use front tools

supple bramble
#

What kind of libraries would you need to use? Most of the time they are related to auth and routing which you don't need to care about in django, yes maybe lottie files for animations but quite sure you can do something like that with pure js too

inland oak
#

Not sure. I saw react only from afar. I can say that they have that Redux library, that allows them to control state of multiple things going in front more easily

#

It makes them use Design Pattern State at library level I think

inland oak
#

this thing mentions front tools for frontenders

Hello, so I have a python script that has a while loop, prints like 4 outputs per sec,
now I need these 4 outputs to keep updating the html without the need to reload, so like the html keeps updating nearly in real time with the new outputs, any help?

#

I really can't figure it out

vestal hound
#

but it is a bit odd

#

you will see APIs that use POST for more or less everything

#

there are restrictions on non-POST requests

that don't apply to POST requests

def main():
    return sentence()

def run():
    app.run(host="0.0.0.0", port=8080)

run()

I tried this which outputs a letter in a while loop, but the letter won't update unless I reload, also, it removes the previous letter...

You'll want to move your file out of the templates directory and into a directory called static

#

And then the template language you're using should have a tag for static urls (but if that's just regular html, you'll want to use a relative path rather than one that compares to the root of your computer)

you use it like so:

# stark tartan ```python class Post(models.Model): user = models.ForeignKey(User,on_dele...

Instead, I would give Post and ReportPost a one-to-one relationship (as one reported post corresponds to one post). Then, I would add a BooleanField called reported to the Post model. I would override the .save() method of the Post model, or add a post_save signal to ReportPost, which will check if there are any objects on the other side of the one-to-one relationship, if so, reported=True.

Then you can just filter all objects by the reported field...

it returns a boolean, which isn't callable

I get this.

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



if __name__ == "__main__":
    app.run(debug=True)
``` That's the code about the website
#

in my bot file

#

and why do we even bother marking it with is_safe? Just so that Django doesn't have to do unnecessary work and escape output if we know it will be safe?

Hey everybody, i am trying to setup Nginx for my server. Is UWSGI necessary?

patent cobalt
#

You don't have to use uWSGI if you want to go the WSGI-route (which is the most common route). Gunicorn is also a popular option.

native tide
#

What is the difference between them?I don't know much

#

I am a beginner in server deployments, i don't know anything related to WSGI and Gunicorn

#

Only thing i know is NGINX helps to modify some protocols for server requests

patent cobalt
#

NGINX does not "know" how to talk to a Python-application. Django supports WSGI, which is a standardized way to talk to Python web applications. uWSGI and Gunicorn do that "translation step", so you get something like client <---> Nginx <---> uWSGI <---> Python app

Sebastiaan can u help me?

@native tide Your question does not seem to relate to this channel. I think it's best to open a help channel (see #❓｜how-to-get-help) or to find a topical channel that does firt your question.

What Frontend i use with Flask?

native tide
#

My bad am sorry

patent cobalt
#

So, it's not something NGINX knows how to talk to on its own

I am asking because i face with this problem whenever i need to configure something with UWSGI

sudo service uwsgi start
Job for uwsgi.service failed because the control process exited with error code.
See "systemctl status uwsgi.service" and "journalctl -xe" for details.

I think i will try gunicorn. Thanks for the help

There's no single thing that works best, although flask would probably play a slightly different role if you use a full-fledged front-end app like react/angular
