I am planning to rewrite sqlalchemy on async at some point

#

But this is a project for another time

#

i was working on a async version of Django's orm for a bit

rustic pebble Jun 21, 2020, 6:05 PM

#

I dont like django at all

#

feels really heavy and time consuming

quick cargo Jun 21, 2020, 6:06 PM

#

I like the orm i dont like how annoying it is to hack

rustic pebble Jun 21, 2020, 6:06 PM

#

exactly

#

I have some premade templates for most of my services

#

I used to write everything from scratch a while back

#

which resulted in many hours spent on reinventing the wheel

quick cargo Jun 21, 2020, 6:07 PM

#

Im trying out aiohttp stuff more now lol

rustic pebble Jun 21, 2020, 6:07 PM

#

I have kind of built an orm for mysql

#

for async

#

I might release it as a module

Hey friends. Quick question, I just installed Django via cmd after setting up they venv. However my question is:

Do I have to create a new venv for every new project?
Do I have to activate/deactivate the venv for lets say my Blog project everytime I restart the pc?

quick cargo Jun 21, 2020, 7:52 PM

#

that depends

#

if you're running via cmd yes

#

but its pretty easy to make a simple batch strip to activate it

#

and its best practice to use a diffrent venv for diffrent projects

#

to help organise dependencies etc...

#

but no you dont have to

Alright thank you

Is there a way to add a default value to a choicefield in a form in Django? I have a dict of countries with country codes, but I want to include an option that says "all countries" which is actually a null value (and therefore doesn't narrow anything down).

hey, im a beginner with python and a complete noob with Django. I was trying to run a project from github, I tried making a virtualenv but Im not exactly sure how this works. Would someone be able to help (or let me know if this is a bad question, oops!)

pliant falcon Jun 22, 2020, 8:15 AM

#

did you installed virtualenv?

#

@glossy crown

#

first you need to install it same as any package in python.. ```
pip install virtualenv

#

then path to the folder of your project by cd path

#

then create vritualenv by virtualenv virtualenv_name

#

in your project folder a folder created with the virtualenv name that you just created..

#

open the folder then scripts then copy path

#

past it on command line and add \activate at the end

#

virtualenv_name\Scripts\activate

#

i need to print the login form data

#

any idea how to do that?

rustic pebble Jun 22, 2020, 4:22 PM

#

In your html code you have a <form> element which sends the form to /response when its submitted

bleak bobcat Jun 22, 2020, 4:22 PM

#

action="/response" @app.route('/')

rustic pebble Jun 22, 2020, 4:22 PM

#

you need to create a coresponding route

#

basically this:

#

@app.route('/response')
def form_data():
    username = request.form["username"]
    password = request.form["password"]
    print(username, password)

native tide Jun 22, 2020, 4:26 PM

#

400 bad request

#

also, you cant print like that on flask

#

its return

bleak bobcat Jun 22, 2020, 4:27 PM

#

You can still print data to the console before returning a template render

native tide Jun 22, 2020, 4:27 PM

#

KeyError: 'username'

#

need to print it on the website

bleak bobcat Jun 22, 2020, 4:28 PM

#

What's the result of printing request.form ?

native tide Jun 22, 2020, 4:28 PM

#

your username and password

#

but i couldnt load the websit

bleak bobcat Jun 22, 2020, 4:28 PM

#

Well, no, otherwise you wouldn't get a keyerror

native tide Jun 22, 2020, 4:28 PM

#

it went to error

#

yeah

#

#

any idea how to fix?

bleak bobcat Jun 22, 2020, 4:32 PM

#

What's the result of printing request.form ?

native tide Jun 22, 2020, 4:32 PM

#

none?

#

no idea

#

you could put the result inside the html

bleak bobcat Jun 22, 2020, 4:33 PM

#

Just print it to the console for now

native tide Jun 22, 2020, 4:33 PM

#

Which is ?

native tide Jun 22, 2020, 4:34 PM

#

KeyError: 'username'

bleak bobcat Jun 22, 2020, 4:34 PM

#

Print before trying to access username and password

#

If you print after an error then yea you'll never get your print

native tide Jun 22, 2020, 4:35 PM

#

you just want me to print text?

#

sure

bleak bobcat Jun 22, 2020, 4:35 PM

#

I want you to print request.form before doing anything else in your hello view

Hello folks, I am working on an API using Flask and I am stuck at a problem...
the API uses MVC pattern, the routes are defined in the views and call controller methods to get the data necessary. The problem is that the controller methods return either the queried object from database or None to indicate failure, but the view has no idea of what went wrong so it can't distinguish 404 not found from other errors.

#

What/how should I improve to be able to distinguish different types of problems the controller can encounter to return a better HTTP code from the view?

#

I was thinking about returning a tuple containing the object/None and some data but don't know what data would be suitable... returning just the error messages gives the view no hint of what HTTP code it shall return, and returning the HTTP code from controller and just passing it in the view doesn't seem like the right design choice 🤔

#

Any input would be appreciated, if you need more context let me know 🙂

midnight kernel Jun 22, 2020, 9:30 PM

#

@ashen vigil have you tried the @app.errorhandler decorator?

#

I use a bunch of custom exception classes, and with the @app.errorhandler(MyCustomException) decorator, I setup callback functions which return an error message (along with an appropriate status code) whenever MyCustomException is raised.

#

that way, my controller classes don't have to handle anything related to status codes, that job is done with the errorhandler decorator (and the callback functions associated with them)

does anyone know how to get the other side of a M2M relationship including the through model?

#

e.g.:

class LeftSide(models.Model):
    left_value = models.IntegerField()
    rights = ManyToManyField(LeftSide, through=Through)

class RightSide(models.Model):
    right_value = models.IntegerField()

class Through(models.Model):
    left = models.ForeignKey(LeftSide, on_delete=models.CASCADE)  
    right = models.ForeignKey(LeftSide, on_delete=models.CASCADE)
    through_value = models.IntegerField()

if I were to access the rights RightSide set of a LeftSide instance, each instance would have the right_value model field, but not the through_value field from the Through model. how do I get both of them together?

Hey guys, I had a quick question about something I'm trying to do in Django...

    {% for article in articles %}
    <h5 class="articleTitleSection"><a href="/individual_blog/?page=1">{{ article.title }}</a><br> by: {{article.author}}</h5>
    {% endfor %}
</ul>```
So basically I have an Article model which contains the title, author, and content. Right now I can view the first article object at `/individual_blog/?page=1`, the 2nd article object at `/individual_blog/?page=2`, and so on etc.

My question is - What do I change in this href attribute (also seen in the first snippet of code) `<a href="/individual_blog/?page=1">` so it doesn't just always go to the 1st page. Instead, if the user were to click on, say, the 2nd link, it brings them to the second page, not just the 1st.

@midnight kernel I have gone through many MVC API projects using flask on GitHub and came to this conclusion too. Majority of them doesn't even use controller with views, or uses views for static .html files. Would you mind sharing your project for reference if it is public?

You need to make sure you own javascript

#

especially classes and objects

distant trout Jun 23, 2020, 1:36 PM

#

hmm

#

yeah i got a long way to go Xd

#

is there an easy alternative?

#

or should i stick to css

#

using flexbox/css grids

#

and frameworks like bootstrap

rustic pebble Jun 23, 2020, 1:37 PM

#

Just learn 2-3 styling frameworks

#

and then start diving into heavy javascript

distant trout Jun 23, 2020, 1:38 PM

#

styling frameworks?

#

could u name some, not familiar with that term

#

like bootstrap and tailwind?

Hey guys, I'm trying to learn Django and am having this weird issue where python manage.py startapp <myAppName> seems to execute twice. Here's what I've done:

Created a virtual environment using python -m venv myVenv
Began using this venv by using source myVenv/bin/acivate
Installed django using pip install django
Created a Django project using django-admin startproject myProjectName
Attempted to create an app using python manage.py startapp <myAppName>

I believe step 5 is executing twice because this is the result inside <myProjectName>. I also double checked that Django is only installed once using pip list

📎 Screen_Shot_2020-06-23_at_10.13.13.png

#

Also, which python confirms I am using the Python from my virtual environment

quick cargo Jun 23, 2020, 2:29 PM

#

why do you have two of every file?

#

oh yes

#

i see

random rose Jun 23, 2020, 2:30 PM

#

yeah thats my question haha

quick cargo Jun 23, 2020, 2:30 PM

#

you might need to delete it all and do it again

random rose Jun 23, 2020, 2:30 PM

#

i tried

quick cargo Jun 23, 2020, 2:30 PM

#

ive never had that issue before xD

#

it still doing it?

random rose Jun 23, 2020, 2:30 PM

#

i also tried quitting everything and resourcing my venv

#

yes

molten quarry Jun 23, 2020, 2:31 PM

#

That is funky.

Not exactly a solution, but I would check out dockers. Started using them myself recently. Amazing. Makes life so much easier. Small curve, but totally worth it.

random rose Jun 23, 2020, 2:31 PM

#

If it's relevant, I'm using Django 3.0.7 on MacOS 10.15.5

#

ill look into dockers

#

oh docker is a venv thing

#

i dont think its an issue with my venv becuase creating the project itself yielded no issues

#

jk its def a venv thign

#

django-admin yields two of every command available

molten quarry Jun 23, 2020, 2:33 PM

#

You wouldn't have the venv open twice or something right?

random rose Jun 23, 2020, 2:33 PM

#

I don't believe so

#

when i deactivate once it returns to my default python environment

#

hmmm strange

#

i called pip uninstall django

#

and it worked

#

and django is no longer working

#

but it still appears in pip list

#

i think im going to generate a new venv

molten quarry Jun 23, 2020, 2:34 PM

#

Try using pipenv

#

pip install pipenv

#

pipenv install django

#

Once it's done, activate the environment using "pipenv shell"

random rose Jun 23, 2020, 2:36 PM

#

creating a new venv did the trick

#

super weird

#

django was double installed or something

#

ty for your help though ❤️

molten quarry Jun 23, 2020, 2:36 PM

#

🕺

#

Some tips that helped me out a lot during the Django basics: When following your tutorial/book, use VERY descriptive model names/view names. "model_MODELNAME*, "view_VIEWNAME".

Hardest part of Django (or any framework) at first is learning to separate what's python code and what's Django framework.

#

Everything is gonna feel mixed and it's hard to tell where things are coming from

random rose Jun 23, 2020, 2:40 PM

#

gotcha good to know ty

#

one quick q as well: I'm following corey schafer's 2.1 tutorial and read there arent a ton of breaking changes in 3.0. Is this true? Or should I just look for a 3.0 tutorial

#

I just like Corey Schafer's teaching style : P

molten quarry Jun 23, 2020, 2:41 PM

#

The core Django foundations are solid. They haven't changed.

Hi guys, is there a tool where u guys use in order to build web design? For example like there is Elementor for wordpress, so looking for something that is standalone that can generate code (lets say for bootstrap or anything u think)

Dont know if this goes into this category, but how do i get rid of everything except the 21 in this line? : <span class="temperature temperature--warm" role="text">21<span aria-label="grader celsius" class="temperature__degree" title="grader celsius">°</span></span>

molten quarry Jun 23, 2020, 7:55 PM

@rigid mist Sounds like a parsing job. If you're making a python script, you can use bs4 (BeautifulSoup 4)

rigid mist Jun 23, 2020, 7:56 PM

I am, but i dont know how to "aim in" on the 21, it being text, but not a por h1, h2, h3 or h4.

huys how to prevent user from downloading images and videos on site in flask??
@fickle fox
Impossible

#

By viewing it in the browser, they downloaded it

fickle fox Jun 23, 2020, 8:40 PM

#

oh i heard netflix protected it from downloading

#

so i was wondering how its possible

unkempt snow Jun 23, 2020, 8:40 PM

#

I dont think its possible to protect, most of the difficult sites to get the video from use chunks, but its still possible to download it

fickle fox Jun 23, 2020, 8:42 PM

#

chunks?

unkempt snow Jun 23, 2020, 8:42 PM

#

as in, send 4-5 seconds in every GET request

#

so its sends the video split into many chunks instead of in 1 file

#

however its always possible to mix those and create it into 1 file

fickle fox Jun 23, 2020, 8:43 PM

#

oh so thing i saw was lie

#

if there is way to protect it i d like to use it for sure

#

but tq

unkempt snow Jun 23, 2020, 8:43 PM

#

There are multiple video security providers which makes it hard to do so

#

not sure waht they are using exactly, but there are way to make it difficult to do so

#

however, never impossible

rustic pebble Jun 23, 2020, 9:00 PM

#

@fickle fox I dont rly thinking netflix uses the request to increase the security of their services but to, rather, increase the performance, by downloading the video in chunks the buffer time is minimal

can someone tell me if i always have to start off making my website responsive?

#

can i just add in media query when every thing looks fine on a desktop 1920x1080 monitor?

rustic pebble Jun 23, 2020, 9:01 PM

#

Yes you can add a media query but you will need to adjust the mobile version of your website accordingly

#

it wont magically fit into place

distant trout Jun 23, 2020, 9:02 PM

#

ahh

#

do people usually make responsive website from the start?

#

or do it at the end of a project

rustic pebble Jun 23, 2020, 9:03 PM

#

It depends, I usually layout the design at my best capability, making it responsive filling it with demo data - placeholders, then I proceed into building the backend which will then fill the place of the placeholders

#

That is my opinion and method, doesn't mean you have to follow it

#

If you got a solid plan in your head you can jump in the backend, build everything and then just leave the design for last

#

I like to see the frontend rollout as I build the backend, so having an already existing frontend base feelsgood

distant trout Jun 23, 2020, 9:04 PM

#

ahh

#

sounds very structured

#

the way u do it

#

thank you

rustic pebble Jun 23, 2020, 9:04 PM

#

Well, yeah

#

I like to structure my development process into models

distant trout Jun 23, 2020, 9:05 PM

#

models?

#

like the frontend/backend?

rustic pebble Jun 23, 2020, 9:05 PM

#

I use the MVC model, model - view - controller

#

Basically, view makes a request, a controller takes that request, processes it and updates the model, then the view is updated and user sees the result

distant trout Jun 23, 2020, 9:07 PM

#

ohh nice

#

i started learning flask for that

rustic pebble Jun 23, 2020, 9:07 PM

#

Well

#

Once you start scaling things you will refrain from using sync frameworks

Hi, I'm making a simple server with flask and while I'm ~~copy-pasting tutorial~~implementing login I found that the session doesn't get saved. What am I doing wrong?

@app.route('/login', methods=['POST'])
def login():
    print("Last session")
    print(session)
    req = request.values
    if 'id' in session.keys():
        return {"message": "Already logged in"}, 200
    else:
        res = helper.login(req['id'], req['password'])
        if res:
            session['id'] = req['id']
            session.modified = True
            print("After changing")
            print(session)
            return {"message": "Logged in"}, 200

    return {"message": "Invalid credential"}, 401

output :

Last session

take a look at that and change the secret key

#

What do you guys use to compress images for web (decrease their buffer). Is Pillow good enough or?

#

@native tide

#

I'd recommend you use flask-login

#

Flask-Login provides user session management for Flask. It handles the common tasks of logging in, logging out, and remembering your users’ sessions over extended periods of time.

#

@native tide it was to hide my key xD
ill check out that, thanks

#

import os

SECRET_KEY = os.environ.get('SECRET_KEY')

use that to hide the important data

a.k.a environment variables

can you send me the snippet ?

When i try running manage.py migrate

rancid crane Jun 24, 2020, 10:43 AM

#

pub_date = models.DateTimeField(auto_now=True, null=True, blank=True) this is where is comes right>>

??*

dreamy pecan Jun 24, 2020, 10:44 AM

#

When i did the first makemigrations thats the line the error popped but now it does not specify which line throws the error.

rancid crane Jun 24, 2020, 10:45 AM

#

can you remove blank=True and then give it a try?? from pub_date

#

and make migration again

dreamy pecan Jun 24, 2020, 10:45 AM

#

Let me check.

rancid crane Jun 24, 2020, 10:46 AM

#

if your pub_date is auto_now then why u need it null?

#

database can auto fill this field when u submit the data

dreamy pecan Jun 24, 2020, 10:47 AM

#

I had it like that checking some stuff from stackoverflow.

#

Did the change but same error.

rancid crane Jun 24, 2020, 10:49 AM

#

pub_date = models.DateTimeField(auto_now=True)

#

and try add default=None

#

like this

dreamy pecan Jun 24, 2020, 10:50 AM

#

Before adding the DateTimeField it was smooth then added a couple more fields. That's when the error popped out, then django started whinning about setting defaults to each field.

rancid crane Jun 24, 2020, 10:50 AM

#

models.DateTimeField(auto_now=True, default=None

like this
@rancid crane )

#

models.DateTimeField(auto_now=True, default=None) try this

then make migration

Yeah.

rancid crane Jun 24, 2020, 10:58 AM

#

models.DateTimeField(auto_now=True) you can try this also

#

let me know it this worked

#

if it works*

dreamy pecan Jun 24, 2020, 10:59 AM

#

Threw me this: ```(django3.0.7-3.8) E:\Dev\fritolaypromo\LandingPage>python manage.py makemigrations
You are trying to change the nullable field 'pub_date' on promo to non-nullable without a default; we can't do that (the database needs something to populate existing rows).
Please select a fix:

Provide a one-off default now (will be set on all existing rows with a null value for this column)
Ignore for now, and let me handle existing rows with NULL myself (e.g. because you added a RunPython or RunSQL operation to handle NULL values in a previous data migration)
Quit, and let me add a default in models.py```

rancid crane Jun 24, 2020, 11:00 AM

#

models.DateTimeField(auto_now=True) you can try this also
@rancid crane if this didnt worked then in case

#

models.DateTimeField(auto_now=True, default=True) should worked 😦

dreamy pecan Jun 24, 2020, 11:03 AM

#

Hope all these previous migrations i have done are not getting in the way. Should i rollback to when it worked fine then apply your suggestions?

rancid crane Jun 24, 2020, 11:03 AM

#

if you dont have any existing records and this is your testing server then you can

#

just delete a migrations EXCEPT init.py ie in the folder migrations

#

all migrations*

#

then

#

u need to delete the table in the postgres

#

all tables in the postgress

Hi guys,
I have a model, called "Blog", which has a date property. I need to order my blogs by date, descending. Why is this so difficult? At the moment I do the following:
Blog.objects.order_by('date').reverse()
How do you use the asc() and desc(). I do not understand the Django documentation regarding this.

dry pawn Jun 24, 2020, 1:38 PM

#

@raw drum You can use Blog.objects.order_by('-date').

raw drum Jun 24, 2020, 1:51 PM

#

@dry pawn Damn. Thanks for that. Now that I read the documentation again, slowly, I see the "-" is used for desc:

src is meant to tell the browser where to find the picture. If browser cannot open url specified by src, it cannot work.

dry pawn Jun 24, 2020, 2:15 PM

port 8000 is your Django application I guess. So you either need it to serve the pictures, or you need another server to serve the pictures. Or you must encode your pictures in base64 (https://stackoverflow.com/questions/8499633/how-to-display-base64-images-in-html).

bleak bobcat Jun 24, 2020, 2:15 PM

Yea but not only

snow sierra Jun 24, 2020, 2:16 PM

ok ok ... i was trying without static .. i'll do with that django docs ..

#

i through if HTML gives me path of image then <img src ... > must work :d

dry pawn Jun 24, 2020, 2:18 PM

#

The idea is that browser will fetch html, analyze html, see the src attribute and then fetch picture using provided url. So provided url must serve picture.

snow sierra Jun 24, 2020, 2:19 PM

#

thank you mates 🙂

#

look at this

{% load static %}
<img src="{% static "my_app/example.jpg" %}" alt="My image">

but here i want dynamic image as said above ... {{i.photo}} because every student have own pic ..

bleak bobcat Jun 24, 2020, 2:26 PM

Then it's media, not static. You need to add uploads dir to the media files django should serve

I want to save images in the static directory (situated in the root directory of my application).
What works for me is creating an image path like this

image_path = os.path.join(current_app.root_path, current_app.config['IMAGE_DIR'], safe_filename)

However, if I try to use url_for for relative paths and say

image_path = os.path.join(url_for('static', filename='assets/images'), safe_filename)

it doesn't work anymore. Anyone knows why?

Fussing with Django REST. Is there a good method for serialization for extra actions? Because I can specify this:

@action(detail=False, serializer_class=MySerializer, methods=['post'])

Mostly doing that so it'll self document ~~because I'm lazy~~

Forgive my naivety, but I'm trying to follow Corey Schafer's "Learning Django" series and am having an issue when calling python manage.py makemigrations. I get the following error:

CommandError: Conflicting migrations detected; multiple leaf nodes in the migration graph: (0001_initial 3, 0003_logentry_add_action_flag_choices in admin; 0001_initial 3, 0011_update_proxy_permissions in auth; 0001_initial, 0001_initial 3 in sessions; 0001_initial 3, 0002_remove_content_type_name in contenttypes).
To fix them run 'python manage.py makemigrations --merge'

#

It says to call python manage.py makemigrations --merge, so I do. Doing that yields another error:

Hi guys, I'm trying to get started with Python and my main goal is to make little **online ** projects for practice and obviously if I'm going to get better, I'll do more complicated things. However as a complete beginner I'm not really sure if Python is a correct language for this matter. My friend who is working at my company's IT department said that for Python you usually need to use Linux for things to work 100%. But I don't really want to use Linux, is that really a thing?
Also if it's not the case, could anyone give me a roadmap or some kind of guide on what are the most important things to understand and what beginner projects usually people make to practice?

Well sorry for the wall of text, but I got addressed here from an another forum to chat :d

wind escarp Jun 24, 2020, 6:55 PM

#

Python can be installed on Windows and so works on it, I don't know what your friend really meant.
For online projects, do you mean websites? Desktop apps? Mobile apps? Scripts?
These all can be done with python and since it's a scripting language, it can be used for building websites as well, I have had some experience with it but it's not solid yet and I haven't work on my own projects.

verbal obsidian Jun 24, 2020, 6:57 PM

#

Python is not a scripting language.

#

You don't need to run it in linux to make 'things work 100%'

#

For your use, it'll be allright to use any os, it is true that there might be a few OS dependant libraries but you will most likely not be affected by this.

you don't need one in django iirc

native tide Jun 24, 2020, 8:33 PM

#

@opal robin I m not sure then, but review the tutorial you might have missed sth

#

you don't have a static directory, but still you are mentioning it in the html file

#

btw learn html, css, and python before going further, its just extremely dumb not to

#

you can add a js script reloading it when submitted

opal robin Jun 24, 2020, 8:34 PM

#

you don't have a static directory, but still you are mentioning it in the html file
@native tide i aslo tried creating a directory named static

okay byeee

and than placing assets isntead of it

#

anyway thank you

#

okay byeee
@native tide why do you have to be so rude

native tide Jun 24, 2020, 8:35 PM

#

@barren salmon you need to use redirect instead of rendering the template again

#

@opal robin dude your literally coming here with absolutely no knowledge

opal robin Jun 24, 2020, 8:36 PM

#

that's not true

#

i'm new to django

not to python

Laravel or Django?? which is strong in web what you think guys ..

native tide Jun 24, 2020, 8:38 PM

laravel is more common

snow sierra Jun 24, 2020, 8:39 PM

same ..

#

but php vs python 🙂 is not compareable thing ...

native tide Jun 24, 2020, 8:41 PM

#

php is still more common

#

if you ran into any issues you would most likely have better luck finding them if you were using php

#

and it is easier to host on a web server

snow sierra Jun 24, 2020, 8:43 PM

sure !... why i asked it :dd i don't know, just was typing something :dd

i think we can compare Laravel to Wagtail and not to django.. 🙂

hello

limpid verge Jun 25, 2020, 5:58 AM

#

Does anyone know what is the Purpose of Using DurationField in django

native tide Jun 25, 2020, 7:43 AM

#

@distant trout this is not a CSS group but it depends on what you actually do. Naming columns might be really useful if you have a repetitive design on multiple pages.

#

example

#

    grid-template-columns: [sidebar-start] 8rem [sidebar-end full-start] minmax(6rem, 1fr) [center-start] repeat(8, [col-start] minmax(min-content, 14rem) [col-end]) [center-end] minmax(6rem, 1fr) [full-end];

#

here you know that the first column from sidebar-start to sidebar-end you have the navigation bar; then full-start to full-end you have an entire section spanning from the navigation bar to the end of the document width

#

You can get more organised if you know what you're doing.

i tried each of the last 2 lines

yup

do you have a route in your main file

?

Assuming the main.py script you posted is not redacted, you're potentially missing the actual route.

put

@app.route('/')

    return 'hello world!'

in your main

as said above, this site works on flask's dev server

so i have everything set up on the flask side of things

Description: fast, self-healing application container server
 uWSGI presents a complete stack for networked/clustered web applications,
 implementing message/object passing, caching, RPC and process management.
 It uses the uwsgi protocol for all the networking/interprocess communications.
 .
 uWSGI can be run in preforking, threaded, asynchronous/evented modes and
 supports various forms of green threads/coroutines (such as uGreen, Greenlet,
 Fiber). uWSGI provides several methods of configuration: via command line,
 via environment variables, via XML, INI, YAML configuration files, via LDAP
 and more.
 .
 On top of all this, it is designed to be fully modular. This means that
 different plugins can be used in order to add compatibility with tons of
 different technology on top of the same core.
 .
 This package depends on uWSGI core binary and installs:
  * init.d script for running uWSGI daemon(s) with options defined in custom
    user-created configuration files
  * infrastructure for running daemons (like common locations of communication
    sockets, logs)

native tide Jun 25, 2020, 11:09 AM

#

yea, it was the only thing that would get uwsgi to work

#

apt-get install libssl-dev
pip install uwsgi -I --no-cache-dir

found this on SO

#

so

#

ok

#

i see it loading flask, then dying

#

(also i forgot, in my messing, i tried to run flask with SSL earlier)

#

which did work, to run flask standalone

native root Jun 25, 2020, 11:12 AM

#

right, so the deal here is it's unable to find the stuff that tells it what to run

#

normally there's an ini file but you SHOULD be able to just point it at your file with a wsgi app in it

native tide Jun 25, 2020, 11:13 AM

#

import sys
import importlib
sys.path.insert(0, "/home/crazygmr101/ansura/website")
from main import app as application

#

thats my ansurasite.wsgi

#

in same dir as main.py

native root Jun 25, 2020, 11:14 AM

#

What's the command you're using?

native tide Jun 25, 2020, 11:14 AM

#

i tried uwsgi --http-socket :9090 --wsgi-file ansurasite.wsgi

#

not sure how else i'd 'point' it at the wsgi

native root Jun 25, 2020, 11:15 AM

#

Well, we can see here it's looking for "/ansura/website/uwsgi" despite you passing in ansurasite.wsgi

#

those are quite different

native tide Jun 25, 2020, 11:16 AM

#

/ansura/website/uwsgi also doesnt exist

native root Jun 25, 2020, 11:17 AM

#

Try specifically doing ansurasite/wsgi.py

native tide Jun 25, 2020, 11:18 AM

#

that doesnt exist either tho

#

ansurasite.wsgi - thats not a literal *.wsgi file?

native root Jun 25, 2020, 11:18 AM

#

right

#

its a wsgi.py file, presumably?

native tide Jun 25, 2020, 11:18 AM

#

uh no

native root Jun 25, 2020, 11:18 AM

#

oh

#

try just pointing it at main.py

native tide Jun 25, 2020, 11:18 AM

#

also this works

📎 unknown.png

native root Jun 25, 2020, 11:18 AM

#

yeah

#

exactly

native tide Jun 25, 2020, 11:18 AM

#

should i try enabling ssl or

native root Jun 25, 2020, 11:19 AM

#

wsgi-file expects a config file

#

and an app name to load from it

native tide Jun 25, 2020, 11:19 AM

#

ah oki

native root Jun 25, 2020, 11:19 AM

#

and main.py:app works

#

no, if you're using wsgi apache does ssl for you

native tide Jun 25, 2020, 11:19 AM

#

alr

#

uh

native root Jun 25, 2020, 11:19 AM

#

Now that you've got wsgi working you should be able to use a unix socket and point apache at it

native tide Jun 25, 2020, 11:19 AM

#

except

#

native root Jun 25, 2020, 11:20 AM

#

Bleh

#

are you in the directory with your main.py?

native tide Jun 25, 2020, 11:20 AM

#

ye

#

📎 unknown.png

native root Jun 25, 2020, 11:20 AM

#

Hm.

#

Bleh

#

dur

#

--wsgi-file main.py --callable app

native tide Jun 25, 2020, 11:21 AM

#

" !!! no internal routing support, rebuild with pcre support !!!" does this matter

#

o

#

ok

#

nope

#

📎 unknown.png

native root Jun 25, 2020, 11:22 AM

#

why's it looking for uwsgi again

native tide Jun 25, 2020, 11:22 AM

#

cuz i removed the :app presumably

#

" !!! no internal routing support, rebuild with pcre support !!!" does this matter
@native tide ^^ and this?

native root Jun 25, 2020, 11:22 AM

#

Unlikely

#

the :app shouldn't matter

native tide Jun 25, 2020, 11:23 AM

#

so.. what do i do :S

native root Jun 25, 2020, 11:24 AM

#

Here's something straight from the wsgi docs that should work:

#

uwsgi --socket 127.0.0.1:3031 --wsgi-file myflaskapp.py --callable app --processes 4 --threads 2 --stats 127.0.0.1:9191

native tide Jun 25, 2020, 11:24 AM

#

uh ok

#

📎 unknown.png

native root Jun 25, 2020, 11:25 AM

#

Well, of course change myflaskapp to your main file

native tide Jun 25, 2020, 11:25 AM

#

oh.

#

right.

#

oworoll

#

📎 unknown.png

native root Jun 25, 2020, 11:25 AM

#

alright

#

next step, is to try basic flask app

native tide Jun 25, 2020, 11:26 AM

#

that works

#

o wait

#

nvm misread

native root Jun 25, 2020, 11:26 AM

#

import flask
app = Flask()

@app.route("/")
def do():
  return "Test"

native tide Jun 25, 2020, 11:26 AM

#

from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello, World, from Flask!"

#

something li- yeup

native root Jun 25, 2020, 11:26 AM

#

Yeah

native tide Jun 25, 2020, 11:26 AM

#

he d o

#

i can just do this in /tmp right

native root Jun 25, 2020, 11:27 AM

#

probably

#

but I'd do it in the same folder

#

just name the file flask_test or something

native tide Jun 25, 2020, 11:28 AM

#

hmmm

#

📎 unknown.png

#

📎 unknown.png

native root Jun 25, 2020, 11:31 AM

#

should use the --wsgi-file test.py --callable app format

native tide Jun 25, 2020, 11:31 AM

#

alr

#

same thing

#

wait

#

you gave me bad code >:(
