Is it possible to have multiple forms on one page using flask.

kindred cosmos Feb 19, 2019, 2:18 AM

#

Yes

#

You would have two different <form> tags with different action values

#

The actions values would be to where the form will post/get too

fossil lotus Feb 19, 2019, 2:20 AM

#

I see so if I have resetUser and resetPass forms, resetUser would go to resetUser.html etc?

kindred cosmos Feb 19, 2019, 2:21 AM

#

Yes

#

Unfortunately, I don't know too much about flask

#

So I have no clue how to implement that

Ah

kindred cosmos Feb 19, 2019, 2:27 AM

You could build a webapp with this so fast lol

lavish prismBOT Feb 19, 2019, 5:05 AM

ask

Asking good questions will yield a much higher chance of a quick response:

• Don't ask to ask your question, just go ahead and tell us your problem.
• Try to solve the problem on your own first, we're not going to write code for you.
• Show us the code you've tried and any errors or unexpected results it's giving
• Keep your patience while we're helping you.

You can find a much more detailed explanation on our website.

@hollow flower A lot of the methods in the Flask-JWT-Extended, specifically a lot of decorator methods, will handle a lot for you. Flask-JWT-Extended's method create_access_token(identity=identity) will create a JWT the same way you do in your encode_auth_token function, where the identity is the user_id

#

then you can handle a lot of those exceptions with decorators

#

@jwt.token_in_blacklist_loader
def token_in_blacklist(decoded_token):
    return is_revoked(decoded_token)

@jwt.invalid_token_loader
def invalid_token_callback(error):
    return jsonify({
        "description": "Signature verification failed.",
        "error": str(error)
    }), 401

@jwt.revoked_token_loader
def revoked_token_callback():
    return jsonify({
        "description": "The token has been revoked.",
        "error": "token_revoked"
    }), 401

#

(the is_revoked(decoded_token) is my own function which checks if the token in the token database table has been revoked)

I've got my image in Static -> Imgs -> b4.jpg but when I specify background-image: url('/static/imgs/b4.jpg) it doesn't work? I've also tried using flask url_for method but doesn't work. Anyone know what's going on?

inland veldt Feb 19, 2019, 4:56 PM

#

I assume you're talking about using that in a template. Your url_for() should look like:
url_for('static', filename='Imgs/b4.jpg')

fossil lotus Feb 19, 2019, 4:57 PM

#

It’s in my css file not template

#

But lemme try that again

inland veldt Feb 19, 2019, 4:59 PM

#

don't think that's going to work in a CSS file. that's a static file, not processed by the app. I think you'd have to include the relevant CSS in a template file.

1 question, so now i registred my user and i want to send activation tocken to his email but how to make it a link, my only logic would to put API endpoint for activation to be GET so i can constucruct URL , or is there some other solution?

fossil lotus Feb 19, 2019, 5:08 PM

#

Don't know if this helps but I watched a video that uses tokens for reset passwords you could try the same way but use to validate the email instead ?

glacial quartz Feb 19, 2019, 5:21 PM

#

what, i need to confirm email exists so i am sending a link to mail so user confirms it

#

i planed to use jwt but would like to confirm by just sending a post request to my server but issue is how to create a post request as link thats why i think i have to use GET request

midnight kernel Feb 19, 2019, 9:01 PM

#

@glacial quartz why would a get request not work?

#

what I do is maintain a database table of activation tokens. I create this token using the token_urlsafe() method of the builtin secrets module. I use 64 as a parameter, which leaves me with an 86 character string. i save these tokens, their creation time, how long i want them to be valid for, and an is_used flag that I set to 0 for an unused token, or 1 for a used token. (can only activate if is_used is 0)

glacial quartz Feb 19, 2019, 9:11 PM

#

@midnight kernel i wanted to use post, but ye am now using GET cuz cant make a post url

midnight kernel Feb 19, 2019, 9:11 PM

#

then i have a route that allows for activating the token VIA a get URL

#

@app.route('/activate/<string:token>', methods=['GET'])
def activate_account_with_token(token):
    msg = auth.activate_acct_token(token)
    return jsonify(msg)

glacial quartz Feb 19, 2019, 9:13 PM

#

duno atm i am just on registration creating a mail with token and email in it

#

and have colum acctivated in user

midnight kernel Feb 19, 2019, 9:13 PM

#

with their randomly generated token associated with an account

glacial quartz Feb 19, 2019, 9:14 PM

#

i am using flask-restfull for some unknow reason xD

#

anyway it works now i just thinked GET is beh wanted to use POST but ye 😃

midnight kernel Feb 19, 2019, 9:17 PM

#

yeah POSTs are a bit harder to do with a single link

#

POSTs are more like, when you wanna send JSON data or form data from something

glacial quartz Feb 19, 2019, 9:18 PM

#

i duno if its even posible to do as link, anyway just now figured out i need to put activated in auth tocken cuz its pointless if i dont have it xD

midnight kernel Feb 19, 2019, 9:18 PM

#

putting an actual parameter (the token) in a link, I can't think of a reasonable way to do that other than a GET

glacial quartz Feb 19, 2019, 9:19 PM

#

yep i know thats why in end ended up using GET

Hello, I'm having trouble writing my django models. I'm usign the spotify api and i want to save the returns as complete models. reference to spotify here :https://developer.spotify.com/documentation/web-api/reference/object-model/ . For example when i requested a track object it comes with a album object,artist object,external_ids, external_urls object inside. My modals file here: https://paste.ubuntu.com/p/vHGKfFKF4C/?fbclid=IwAR3HzjrDhjSrFI6XgnQmzXZ0AvDmpP6Hca4pJqBpXYPOLArTpg_VzNTPIcc . But this way usign foreign keys or onetofields i cant save a track object without saving external urls first and when 5 related fields in a track object is considered it becomes to much code and too many saves within just a function. Should i reconstruct my modal file any recommendations ?

If you don't have that much time, then you might want to try to find a recent Youtube tutorial to learn from.

if you work hard you can prob run through a tutorial like https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django pretty quick

tutorials that run you through everything from the folder layout, databases, templating, authentication and some deployment tend to be enough to get rolling

the app they make is usually somewhat simple but it touches everything you really need

I'm currently making a chat bot for twitch and I'm using django to create a web interface for users, I would like them to be able to authenticate via twitch so I have used the allauth module. I have the redirect to twitch working however even after authenticating on twitch and then redirecting back to localhost from twitch, django still sees the user as an anonymous user, there are no errors, just that the url of the page has redirect_mismatch in it. I've tried all combinations of redirect urls in sites and on the twitch developer app and nothing seems to be working.

native tide Feb 25, 2019, 1:32 AM

I had a similar issue to that, and I just created a model that is an extension of the User model. I made sure that one is created automatically for each user on signup. Then when referencing the user I went through the model.

heavy jewel Feb 25, 2019, 1:41 AM

Thanks, I can do that. What about the data about the user from twitch? it looks like twitch is not returning information because of the url mismatch, would I just have to have them enter their details manually?

Hi people. Any tips for a starting point (ideas) for database/model audit log/trail on Django? Not using third party packages. I'm using. Vue/quasar frontend with DRF backend. I'm after a general approach really. Would you have a single model called audit_log and in there have a single entry which stores user, changed-model(table), etc? But then where to store what field was changed, since this will be different for each changed model type, so can't easily be kept in a single audit log model can it? Anybody got any ideas?

#

Or would you create a _log model for each model that you want to keep a log for? That sounds more manageable/easy to me, but might turn into lots of repetition in the long term and stuff.

outer marsh Feb 27, 2019, 9:23 AM

#

Depends on your use case really. I mean you could make a basic log model, store table row colum pre post. This would also avoid having to alter two models when make changes. When you do make changes to the models and run the migration you can add to the migration script a post to the audit table showing the migrated changes as well. So when you look at it in the future, you can see that hair color colum was deleted but prior to that deletion you can still track previous changes to that model.

#

@rancid lava

rancid lava Feb 27, 2019, 1:23 PM

#

@outer marsh thanks. I'll give that some thought. How about another approach.. what if in every model I have another field that says "superceded_by_id" or something, which basically turns that row into a 'previous record'. Then in my general querysets (where I just want to see current data and not previous data), I just filter to only pull out those where superceded_by_id is null or blank. I'm not sure if this sounds like a terrible idea, or a clever idea. I'm not sure how easy it would be to reconstruct an audit trail from that data then..

#

it could mess up foreign key links..

#

hmm

outer marsh Feb 27, 2019, 1:25 PM

#

You could do it that way. Just reads the data to the same model referencing the parent pk-id in the new data set, just be mindful these interactions when you transition data to archive tables for lts.

#

Then mark the parent as not active, and use the parent ID as a foreign keys. The initial record will reference itself.

#

Eg Select values from table where parent ID = x except from table where active_record=false.

#

And index active_record, pk_id, and other relavent indexable values.

#

Honestly there's a dozen ways you can handle this.

#

If you make an log table and store row column row changes made, update the active record. Then when you need to pull back out the logs you can dynamically do queries for the record you want, since the row, colum, would likely be stored as a str.

rancid lava Feb 27, 2019, 1:34 PM

#

I'll have a go! I'm pretty new to all this. I'm using django models and ORM obviously

#

thanks for your help

outer marsh Feb 27, 2019, 1:34 PM

#

Gotcha, np man. Any time good luck!

rancid lava Feb 27, 2019, 1:34 PM

#

thanks 😃

#

row column sounds pretty easy. my only concern there maybe was that if a column was renamed later, then the stored entry, being a string would be the old name, but.. maybe that's not such a big deal

outer marsh Feb 27, 2019, 2:07 PM

#

Since you will still reference each record independently based on pk,

#

Since you will still reference each record independently based on pk,

#

To be clear when I say row I do mean individual records. So you'd store the row/pk, str(key/column), str(previous value)

rancid lava Feb 27, 2019, 2:12 PM

#

yes that's how I understood it too.. seems pretty easy that. I'm just reading up on existing packages to see if they do stuff that I hadn't thought about though 😃 e.g. django-reversion and django-simple-history

outer marsh Feb 27, 2019, 2:13 PM

#

Yup. You can use packages and save time.

#

But sometimes it's useful to build a thing so you learn how.

rancid lava Feb 27, 2019, 2:19 PM

#

I guess it would look like: changed_row_id, field_name, old_val, new_val, user_id. Unless I was to try to be clever and just reconstruct the order/history (i.e. work out 'new' val each time). I can imagine trying to build up a list where a field has been changed a few times though

#

oh and datetime stamps of course

#

and model_name

unborn terrace Feb 27, 2019, 2:46 PM

#

(This question might be more appropriate in #databases, but this is not strictly a database-question, should we need a "software engineering" channel?)

I am asking myself a question about data model in a web app when it comes to "large" models. Would you consider it a bad practice to split large models into multiple smaller ones using one-to-one relations, e.g., in Django:

from django.db import models

class Foo(models.Model):
    x = models.Field()
    y = models.Field()

    ax = models.Field()
    ay = models.Field()

    bx = models.Field()
    by = models.Field()

Would become:

from django.db import models

class Foo(models.Model):
    x = models.Field()
    y = models.Field()

class A(models.Model):
    foo = models.OneToOneField(Foo, on_delete=models.CASCADE)
    x = models.Field()
    y = models.Field()

class B(models.Model):
    foo = models.OneToOneField(Foo, on_delete=models.CASCADE)
    x = models.Field()
    y = models.Field()

This sounds okay to me in accordance with single responsibility principle, since these "submodels" would obviously encapsulate behavior specific to them.
I have however read several times that "one-to-one relations should be kept for inheritance or third-party model extension", without much more explanations.
What do you guys think? 🤔

#

@unborn terrace I don't know. I know the django docs say what you've said - that one-to-one fields shouldn't be used where it would make sense to just extend the original model, but I am using one-to-one in exactly the way you've said. i have done it because one of my models is imported from another system though, and I wanted to keep the model replicating the source api feed exactly, and then extend it with other models linked via OneToOne fields

Hi, I'm using Flask for creating a website. I know it's possible to create role based authorization (or use flask-login for it) but I was wondering if it's possible to create role based routing (and how)?
For example

@authenticated.route('/Home
@login_required('admin')
def sa_homepage()
    #returns homepage for superadmin

@authenticated.route('/Home
@login_required('guest')
def guest_homepage()
    #returns homepage for guest

The same endpoint, but different function based on the role. OR am I just over complicating this and it would just be fine to have 1 function with a simple if-check to see what role the user is? Thanks

@violet zodiac u from the uk?

violet zodiac Feb 27, 2019, 8:00 PM

rancid lava Feb 27, 2019, 8:34 PM

@violet zodiac I think you should be looking at a client side javascript framework for that. Vue.js. You could look at quasar framework which will make using vue even easier. look at https://v1.quasar-framework.org/start/pick-quasar-flavour and at the Vue Components bit. 3 days is not long enough to learn from scratch though. It wasn't for me anyway, but i'm 37 and learn slowly now I suppose 😉

Quasar Framework Docs

Quasar Framework - High performance Vue.js Material Design 2 compo...

Quasar is a full frontend framework with Vue.js components for high performance, responsive websites, PWA, SSR, Hybrid mobile apps and Electron apps, all using the same codebase.

#

or, I suppose since you only have 3 days, knock it up in jQuery

violet zodiac Feb 27, 2019, 9:30 PM

#

I mean my last hope right now is probably relying on internet resources and templates

#

I'll probably have to find a project online and tweak it...

#

I mean I know how to use QTdesigner but I dont think it's possible to make a webpage with QT

#

Hi anyone here is familiar with TCP servers?

rancid lava Feb 28, 2019, 3:16 PM

#

@native tide doesn't have nothing ?

#

you can do better than that 😉

#

@native tide you can use cors middleware to try to allow the cross origin request, but better option is to proxy from frontend to back end.

#

that's what I am doing with Vue & django-rest-framework. My webpack config proxies to the backend. So everything is on the same origin as far as the browser is concerned.

#

@native tide e.g. inside my webpack config: devServer: { host: 'my-hostname.whatever', // https: true, // port: 8080, open: true, // opens browser window automatically proxy: { '/api' : { target: 'http://localhost:8000', secure: false }, '/static' : { target :'http://localhost:8000', secure: false }, '/admin' : { target: 'http://localhost:8000', secure: false }, '/__debug' : { target: 'http://localhost:8000', secure: false }, '/auth' : { target: 'http://localhost:8000', secure: false }, '/accounts' : { target: 'http://localhost:8000', secure: false } }, },

#

might also need to put an entry in your /etc/hosts or %windir%\system32\drivers\etc\hosts with my-hostname.whatever pointing to 127.0.0.1

#

maybe

#

rancid lava Feb 28, 2019, 3:26 PM

#

@native tide essentially your issue is that back end and front end, whilst being on the same host (localhost) they are on different ports (:8000 and :5000), which is why you must proxy and just access all on the front-end port.

patent cobalt Feb 28, 2019, 11:05 PM

#

It's fairly easy, the documentation has some info on it here: https://docs.djangoproject.com/en/2.1/howto/deployment/wsgi/

#

Obviously, more advanced setups require more planning

#

So, it depends a bit on how complicated your production environment is

Just deploying the basic tutorial for "home" use should be fairly straightforward

Setting up a production environment for a large organization is something else entirely

Hello all. I am looking for some insight. I have been coding with python for a few year self taught. Just to automate some jobs at work, working a lot with requests, and then transforming the data and doing things with it. Wether it be a Telegram bot or iterating over csv files etc. I wanted to start working with some web application stuff with python since its the language im the most comfortable with. And I am going thru a little tutorial and in the example the database used in sql. In all of my past examples with retrieving data its always in a json response. Any little project I've already created stores everything in that structure. Is it possible to use sql and still query response in json?

still briar Mar 2, 2019, 2:22 AM

#

You'd only need to use one. If you're unfamiliar with sql or don't want to use it, you could store your data with json.

woeful vapor Mar 2, 2019, 2:23 AM

#

I'm ok with sql i know how to query I just can't understand it in from a web development point

#

especially when dealing with arrays

#

What database would I be storing json to?

still briar Mar 2, 2019, 2:24 AM

#

If you're using sql there's no need to use json, is my point.

#

What kind of data are you interested in storing?

woeful vapor Mar 2, 2019, 2:27 AM

#

I'm plan on developing a game

#

so I would be storing data per game

#

The idea is to create and start the game from the web interface. I will then scrape a separate API at an interval for changes being made within the game being played updating all values in the database. Which would then update the web UI without a refresh (very important)

#

I have a text based version of this working but it is not asynchronous so multiple games can't be ran at once. And all data is stored in memory

still briar Mar 2, 2019, 2:31 AM

#

Right, reactive frontend and perhaps even a socket connection to speed up communication.

woeful vapor Mar 2, 2019, 2:32 AM

#

teams = {'Team1': { name: 'Team Name', "players": [{name:Player, stats:{kills:0, deaths:0, wins: 0}] },{'Team2': { name: 'Team Name', "players": [{name:Player, stats:{kills:0, deaths:0, wins: 0}] }

#

Something similar to this is how I am storing it in memory now

still briar Mar 2, 2019, 2:36 AM

#

Is each team an active session or the teams in one session?

woeful vapor Mar 2, 2019, 2:36 AM

#

one session

#

two teams per session

still briar Mar 2, 2019, 2:38 AM

#

When you talk about json, do you mean that you store this dictionary in a file, or just that you keep the data in a dictionary?

woeful vapor Mar 2, 2019, 2:38 AM

#

keep the data in a dict

#

never store it - script runs and actually use google sheets api to write data to a sheet and update the sheet as time goes on

#

end users can view the sheet for the score changes of the game

still briar Mar 2, 2019, 2:40 AM

#

Sure.

woeful vapor Mar 2, 2019, 2:40 AM

#

rather than use this hacky way. I was going to try and implement in a web applicatioln

still briar Mar 2, 2019, 2:41 AM

#

Then your server will keep the data for the active sessions locally, and will have to upload it whenever it sees fit.

#

What part of the client-server API do you have?

woeful vapor Mar 2, 2019, 2:41 AM

#

What do you mean by that?

still briar Mar 2, 2019, 2:42 AM

#

What code do you have so far?

woeful vapor Mar 2, 2019, 2:43 AM

#

I have the full code written for the example I stated above. Nothing using Django + React

#

was going to start following some tutorials and when I did it was recommending sql as the server for django and if your not going to use some form of sql then your not really leveraging the benefits of django

still briar Mar 2, 2019, 2:48 AM

#

Right, Django has an entire SQL querying toolkit that you'll be using. You'll set up your data using models.

#

from django.db import models

class Person(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)

#

There's a lot to explain here, so I'd suggest looking up a Django tutorial. They cover models and databases which allows you to store your Games, Users, Sessions and all kinds of stuff.

woeful vapor Mar 2, 2019, 2:50 AM

#

the websocket thing looks really interesting

still briar Mar 2, 2019, 2:51 AM

#

It's very useful and allows for direct communication between the client and the server.

#

Normally, the server isn't able to ping the user when something updates, but with sockets the server can announce players actions to everyone.

#

Last time I worked with Django and reactive web design, I was making an online board games site. For active games, I used a Redis database which keeps session specific data as long as it's in use, although it took a while to set up.

woeful vapor Mar 2, 2019, 2:53 AM

#

Not sure if its a problem but I am scraping a separate API from the PC game I am building this for. So not sure how I'd build events off that

#

All seems a bit above my head so I better start small

still briar Mar 2, 2019, 2:55 AM

hi
how do i automatically update a django page without refreshing the page manually

still briar Mar 2, 2019, 2:57 AM

#

👍

#

You want the client to change to a different page without refreshing? That will require some frontend coding.

fast narwhal Mar 2, 2019, 3:01 AM

#

no basically i want it to be connected to a web socket. When the websocket is not on it shows the next shows time and prize. when the show is on it shows different variables like questions, players remaining etc. When the websocket is active or some variables change how do i update the page with out refreshing it.

still briar Mar 2, 2019, 3:02 AM

#

You'll need to get familiar with reactive programming for your front-end.

#

Essentially, updating the client html without refreshing. The client communicates with the server via http requests or websockets, and upon receiving data, you'll have to insert it however you please.

#

There are various frameworks for easy reactive programming, such as React or Vue, but you can do it with some basic javascript or jquery yourself.

fast narwhal Mar 2, 2019, 3:04 AM

#

would django channels do the job?

still briar Mar 2, 2019, 3:06 AM

#

No, that's just a protocol on the server. You still need javascript on the client to load things as they come.

#

How does your frontend client code look at the moment?

fast narwhal Mar 2, 2019, 3:07 AM

#

basically my views.py file get the variables and send to my frontend

still briar Mar 2, 2019, 3:08 AM

#

Yes, but your frontend, the webpage, needs to call an url that links to the server.

#

If you've only made a static page, the client will only visit the url once and nothing will update.

#

But by using javascript, you could manually call something like website.com/get_all_players and receive a list of players from the server.

#

Done this kind of thing before?

fast narwhal Mar 2, 2019, 3:14 AM

#

nope

still briar Mar 2, 2019, 3:21 AM

#

Yes exactly!

fast narwhal Mar 2, 2019, 3:21 AM

#

ok

still briar Mar 2, 2019, 3:22 AM

#

Normally what happens is that when you load a webpage, the client sends a http request to the server, and the server returns html that is loaded into the browser.

#

When you want to update the website without refreshing, you'll need to make that http request yourself, which allows you to do whatever you want with the data that comes back.

fast narwhal Mar 2, 2019, 3:29 AM

#

wait so this is the code

#

function init() {
  refresh()
  var int = self.setInterval(function () {
    refresh()
  }, 10000);
}

</script>

#

would i have to change the req.open to the variable I want to refresh

still briar Mar 2, 2019, 3:31 AM

#

req.open("GET", "/get_something", true)

#

This will make req call that function in your views.py

fast narwhal Mar 2, 2019, 3:32 AM

#

in my code i acess it by saying {{NextShowTime}}

still briar Mar 2, 2019, 3:33 AM

#

The req.onreadystatechange function is called when the server returns something. To start off, you could change the document.getElementById... thing to console.log(req.responseText);

#

That's a template variable in the html.

#

What does your views.py look like?

fast narwhal Mar 2, 2019, 3:34 AM

#

from django.shortcuts import render
from . import networking

def home(request):
    context = {
        'NextShowTime': networking.NextShowTime,
        'NextShowPrize': networking.NextShowPrize,
        
    }
    return render(request, 'hqsite/beforegame.html', context)

still briar Mar 2, 2019, 3:35 AM

#

Ok, let's add another function here!

fast narwhal Mar 2, 2019, 3:36 AM

#

ok

still briar Mar 2, 2019, 3:36 AM

#

You should have a urls.py as well, right?

fast narwhal Mar 2, 2019, 3:36 AM

#

yeah i do

still briar Mar 2, 2019, 3:36 AM

#

Let's see that one.

fast narwhal Mar 2, 2019, 3:36 AM

#


from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('hqsite.urls'))
]

still briar Mar 2, 2019, 3:38 AM

#

Not entirely sure what hqsite.urls is supposed to be, but somehow it calls home?

fast narwhal Mar 2, 2019, 3:38 AM

#

yeah

still briar Mar 2, 2019, 3:40 AM

#

Then where is home specified?

fast narwhal Mar 2, 2019, 3:41 AM

#

i have a urls.py in the same folder as my views.py

#

from django.urls import path
from . import views
#from users import views as user_views

urlpatterns = [
    path('', views.home, name='hq-home'),
    #path('register/', user_views.register, name="register")
]

still briar Mar 2, 2019, 3:41 AM

#

Yes ok, that makes more sense. This is the one you need.

#

Here, you can add a new path to a new server call you wish to add. Let's add a greeting.

#

path('say_hello/', views.say_hello, name="say_hello"),```

fast narwhal Mar 2, 2019, 3:43 AM

#

ok

still briar Mar 2, 2019, 3:43 AM

#

Next up, we'll add a function in views.py named say_hello.

fast narwhal Mar 2, 2019, 3:43 AM

#

k

still briar Mar 2, 2019, 3:44 AM

#

def say_hello(request):
    return HttpResponse("Hello world")

#

Now, the goal is to have the client use a XMLHttpRequest to call say_hello/

Im trying to make a marketplace alike website, but I need a payment proccesor that allows me to set a commision rate

#

so that whemever someone buys something a percentage goes to me

#

anyone knows a payment proccesor that allows this? I cant find one

opal leaf Mar 2, 2019, 7:39 PM

#

hm i always assumed that the sites that did that took the money from the customer themselves then later paid out to the seller

sacred oasis Mar 2, 2019, 7:39 PM

#

Ye thats possible but it complicates alot of stuff

#

it becomes my responsibility

opal leaf Mar 2, 2019, 7:39 PM

#

yea thats tru

#

i think its typical in the business world though. ie not online

sacred oasis Mar 2, 2019, 7:40 PM

#

apperantly stripe allows to set a commision but there fees are high + they dont accpet pp

#

and btc

opal leaf Mar 2, 2019, 7:41 PM

#

yeah it is DEF more complex
you have to have an account to hold the money paid by the customer, then you need a system that is VERY reliable to keep track of the sellers and what the current status is of each payment
AND you have to handle refunds somehow

sacred oasis Mar 2, 2019, 7:41 PM

#

ye I would probs have to manually review payout requets

opal leaf Mar 2, 2019, 7:42 PM

sacred oasis Mar 2, 2019, 7:48 PM

#

I was just reading somethinbg bout it

#

but is it a payment proccesor

#

or a marketplace maker

opal leaf Mar 2, 2019, 7:50 PM

#

looks like the name of what you want to make is "multi vendor marketplace"

#

yeah not sure yet lol.

#

Built-in payment processing from leading providers: Take payments via Stripe and PayPal. Accept credit cards, Direct Bank Transfer, checks or Cash on Delivery.

#

looks like its software for the site that can interface to payment processors

sacred oasis Mar 2, 2019, 7:51 PM

#

im confused lol

#

is it a platform that allows me to make charges

opal leaf Mar 2, 2019, 7:51 PM

#

What about storage? We do not host or store any of your files or information. This is dependent on your hosting solution.

#

its just software that can do this stuff it looks like

#

and it interfaces to wordpress, so yeah you can customize it

sacred oasis Mar 2, 2019, 7:53 PM

#

hmm I'll have a look at it

opal leaf Mar 2, 2019, 7:56 PM

#

there are other products like this it looks like, i think "multi vendor marketplace" is the magic phrase that will find it all

If I wanted to create a function that would run on a loop for 60 minutes. Is it best to use celery?

#

For example when a user presses a button, it triggers a function to run as a celery task and within that function is a while loop that would run for 60 minutes.

#

I want to create a "game session" that lasts for 60 minutes

lost saddle Mar 3, 2019, 3:08 PM

#

Function run on a loop for 60 mins

#

vs

#

Function loops every 60 minutes

#

Second one is celery

#

First one is depends on the specific situation

woeful vapor Mar 3, 2019, 3:27 PM

#

it would be the first option

#

The idea is that the end user can create a game "session" on the front end. Once they create that session. I want to query an api every minute for 60 minutes, updating my database to pull into a view.

#

So press button - run function, for 60 minutes that loops every minute updating database with an option to stop the loop

#

i thought I would use celery tasks to run that function that way the entire application isn't waiting for the 60 minute loop to finish

Hi all

#

I have an odd situation here.

#

I have a table here that Django is rendering as HTML. And it actually does it correctly. But it results in plain text rather than HTML code.

#

Here's what I have:

#


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    {{ schedule }}
</body>
</html>

#

#resulting html in browser

<!DOCTYPE html>
<html lang="en"><head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    &lt;table border="1" class="dataframe"&gt;
  &lt;thead&gt;
    &lt;tr style="text-align: right;"&gt;
      &lt;th&gt;&lt;/th&gt;
      &lt;th&gt;&lt;/th&gt;
      &lt;th&gt;Mon&lt;/th&gt;
      &lt;th&gt;Hosted by&lt;/th&gt;
      &lt;th&gt;Tue&lt;/th&gt;
      &lt;th&gt;Hosted by&lt;/th&gt;
      &lt;th&gt;Wed&lt;/th&gt;
      &lt;th&gt;Hosted by&lt;/th&gt;
      &lt;th&gt;Thu&lt;/th&gt;
      &lt;th&gt;Hosted by&lt;/th&gt;
      &lt;th&gt;Fri&lt;/th&gt;
      &lt;th&gt;Hosted by&lt;/th&gt;
      &lt;th&gt;Sat&lt;/th&gt;
      &lt;th&gt;Hosted by&lt;/th&gt;
      ...

#

The function generating the table is this:

#

def schedule():
    s = Spread('name', 'table')
    s.open_sheet(0)
    df = s.sheet_to_df(index=2)
    pandas_df = pd.DataFrame(df)
    return pandas_df.to_html()

#

I suppose it's because pandas function .to_html doesn't properly render the dataframe?

#

Figured it out. Had to use {{ schedule | safe }} in the template

Hello, I have a an issue in Django with generic foreign keys, I have these models:

from django.contrib.contenttypes.fields import (
    GenericForeignKey, GenericRelation
)
from django.contrib.contenttypes.models import ContentType
from django.db import models

class Foo(models.Model):
    sub_content_type = models.ForeignKey(
        ContentType, on_delete=models.PROTECT, null=True
    )
    sub_id = models.PositiveIntegerField(null=True)
    sub = GenericForeignKey('sub_content_type', 'sub_id')

class Sub(models.Model):
    foo = GenericRelation(
        Foo,
        content_type_field='sub_content_type',
        object_id_field='sub_id',
        related_query_name='sub'
    )

    class Meta:
        abstract = True

class Bar(Sub):
    ...

Obviously ran makemigrations, added contenttypes to apps and stuff.
The issue when I am trying to create a Foo, like this:

bar = Bar.objects.create()  # ok
foo = Foo.objects.create(sub=bar)  # error

The last line raises the following error:

TypeError: Direct assignment to the reverse side of a related set is prohibited. Use sub.set() instead.

After triple-checking docs and SO, I still can't find the issue, do you see something wrong here?

Hey there!
I wrote a small flask API and I want to run it on my Digital Ocean VPS, I have nginx running on port 80 too which is for my php image uploader (which I didn't code but it works).
So my goal is to run flask script on port 5555 along with nginx and bind it to one of my domains, I tried following one of Digital Ocean tutorials but it didn't work. I checked did I do the steps right and even asked my friend to help but we couldn't find the solution to it. I'm on Ubuntu 18.04 and this is the support link I used:

if it can't bind to a port its usually because another process already has it

In this guide, we will be setting up a simple Python application using the Flask microframework on Ubuntu 18.04. The bulk of this article will be about how to set up the uWSGI application server to launch the application and how to configure Nginx to

Yes

meager anchor Mar 5, 2019, 9:43 PM

#

are you dropping privileges in the uwsgi config?

#

using uid and / or gid

errant fiber Mar 5, 2019, 10:03 PM

#

No, how do I do that?

last week I tried to use this tutorial on my raspberry pi, I dropped after 2 hours and just used gunicorn

What's the best way to throw together a simple bootstrap site? I know the basic structure of bootstrap sites but I'm kinda interested in some tools that'd help me pull together something generic really fast..

#

they're for flask apps, so

#

flask-specific advice is welcome too

#

(I'm good on the backend code. Frontend just messes me up.)

#

I feel like a dork asking for advice on this -- I'm mostly a backend dev, I know I should be decent with HTML/CSS/JS but I just don't have to make user-facing content often enough to be good at it

sharp briar Mar 6, 2019, 3:49 AM

#

You do it yourself.

lost saddle Mar 6, 2019, 4:21 AM

#

Never seen a back-end only python web-dev

prime ridge Mar 6, 2019, 5:07 AM

#

@sharp briar boooo. I know that's the obvious "best for me" answer but I'm serious -- I will learn my way around the tools well enough to make something from scratch eventually but there are definitely options out there that make it easier for beginners to slap a frontend on something.

Just looking to see if anyone had any recommendations for ones better than what I've managed to find. ide plugins, stuff like code pin, anything to give me a little bit more substance than copy and pasting from the bootstrap docs

sharp briar Mar 6, 2019, 5:09 AM

wix

#

or buy some shit like webflow

prime ridge Mar 6, 2019, 5:13 AM

#

Like, I basically write a lot of simple tools that just need a web form and to tabulate data

#

but when I try to write interfaces like this... They come out okayyy, but not really. And it'd take me a few hours

#

as opposed to a few minutes.

#

I did look at webflow though

#

Seemed like it was a little more involved than I'm looking for.

prime ridge Mar 6, 2019, 6:09 AM

#

I guess what I'm after is for something to help me prototype/get a first draft of a site for me to expand on. I'm comfortable changing something about a site when I have a good foundation -- but when I build the foundation from scratch it always turns out subpar =/

junior cloak Mar 6, 2019, 6:21 AM

#

You can use a decent ui framework like Bulma or something. Just copy/paste the html for each component

#

Not unlike bootstrap although bootstrap is just not great

prime ridge Mar 6, 2019, 6:21 AM

#

Hmmm. I'd probably have to talk my team into considering a different frontend

junior cloak Mar 6, 2019, 6:22 AM

#

Oh so it’s a team and they want to use bootstrap

prime ridge Mar 6, 2019, 6:22 AM

#

my boss doesn't actually care but one of my coworkers got pissy when I used materialize for something

junior cloak Mar 6, 2019, 6:22 AM

#

Hopefully they don’t plan on doing a react front end or anything

prime ridge Mar 6, 2019, 6:22 AM

#

Hahahah. They tried.

junior cloak Mar 6, 2019, 6:22 AM

#

Bootstrap is bad if you want to use other js like that

#

Then is there budget for a tool that does what you want?

#

I know some decent ones that cost something monthly

#

Fewer or none now that are free

prime ridge Mar 6, 2019, 6:24 AM

#

I just buy my own tools usually. I could get them to pay for it but I'd honestly rather not ask...

junior cloak Mar 6, 2019, 6:24 AM

#

here is bar none the nicest tool of this sort i have ever used: https://pinegrow.com/

Pinegrow Web Editor | Website Builder for Professionals

A professional visual editor for CSS Grid, Bootstrap 4 and 3, Foundation, responsive design, HTML, and CSS. Convert HTML to WordPress themes.

prime ridge Mar 6, 2019, 6:25 AM

#

I've seen this around. One of the only big ones I haven't tried yet

#

I really like https://pingendo.com/ it's just a little light on features. Hoping to find something like that but better.

Pingendo

Design, build and deploy web pages with ease.

junior cloak Mar 6, 2019, 6:25 AM

#

i think its an unlimited trial

prime ridge Mar 6, 2019, 6:25 AM

#

Gonna try Pinegrow.

junior cloak Mar 6, 2019, 6:26 AM

#

yeah pingendo used to be totally free

#

and shittier than pinegrow so i tried it anyway since free

#

no longer free

#

maybe is nicer now

#

i dont use any of these web frameworks but i was still very impresseed by pinegrow

prime ridge Mar 6, 2019, 6:27 AM

#

I tried webflow but it seems engineered toward designers instead of someone looking for something quick-and-dirty.

#

Would take me longer to build something in webflow than to write the HTML/CSS by hand so what's the point... Good for someone, just not for me. Installing Pineflow now

#

pinegrow

#

lol

junior cloak Mar 6, 2019, 6:29 AM

#

well it might be more for designers

prime ridge Mar 6, 2019, 6:29 AM

#

oh btw I work at a school so I get a lot of discounts on software :D

junior cloak Mar 6, 2019, 6:29 AM

#

but engineers dont usuallly use gui prototype either

#

youre seeking something for a rarer use case

prime ridge Mar 6, 2019, 6:29 AM

#

Yeah, I know they don't... It's not like I'm unwilling to learn. I've written everything by hand up to this point

#

it's just, I'm kind of a fetishist for doing things really quickly

#

web design is so slow and tedious and most of the tools I write don't have to look good, it'd just be nice if they did.

junior cloak Mar 6, 2019, 6:30 AM

#

learn a bit of css, and then use tailwindcss 😃

#

fastest layout/design tool on earth once you get the class names down

prime ridge Mar 6, 2019, 6:31 AM

#

ooh

#

So you mostly add classes to objects to stylize them instead of writing CSS... But it's different than bootstrap because the classes are actually visually descriptive, rather than just being generic things like "info" which is blue by default or something for some reason

#

I like.

#

Pinegrow looks very promising, thanks for showing this to me.

junior cloak Mar 6, 2019, 6:38 AM

#

no problem

#

and yes to your analysis of tailwind

#

its not batteries included liike bootstrap but once you memorize the class shortcuts you can make anything in minutes basically

#

as long as you know what you want it to llook like haha

prime ridge Mar 6, 2019, 6:39 AM

#

I imagine I'll pick up more overtime as I work with the output of these programs... Also hmm

junior cloak Mar 6, 2019, 6:39 AM

#

but until thats your job maybe give this trial a go

prime ridge Mar 6, 2019, 6:40 AM

#

I'm not sure I ever do know what I want things to look like. I imagine we'd probably want to figure out what classes we'd want to use to fit our aesthetic which is... yeah, definitely not my job and hopefully never will be!

junior cloak Mar 6, 2019, 6:41 AM

#

yeah plus youd have to get eveyrone to do this

#

its quickly picking up speed in the dev community but its not for everyone

#

its for those who dont use things like bootstrap but still need a very fasst and efficient way to build it and see it instantly and not have separate prototype/final phases

prime ridge Mar 6, 2019, 6:42 AM

#

ahh

junior cloak Mar 6, 2019, 6:42 AM

#

anyways. pinegrow may be good for now

prime ridge Mar 6, 2019, 6:42 AM

#

Yeee. Should do me for these small projects I try to turn around in a day

junior cloak Mar 6, 2019, 6:42 AM

#

haha a day

prime ridge Mar 6, 2019, 6:42 AM

#

I'm insane!

#

Just... not on the frontend

#

(I mostly make, like, data pipeline tools. Talk to this database and this API and this user... blah blah blah)

junior cloak Mar 6, 2019, 6:44 AM

#

sure

limber orchid Mar 6, 2019, 2:06 PM

#

Does anyone here have experience in flask?

#

I've made my first small python-app-in-site-form using some really basic flask stuff

#

but I'm getting odd behaviors that I don't get when I run it locally

#

it's as if it's continuing to store my variables, even after the function 'returns' the html to display

#

(or at least that's my best guess at what's happening)

kindred gate Mar 6, 2019, 2:09 PM

#

What's your code like?

#

It could be due to how browsers cache the information so you might have to force restart it

limber orchid Mar 6, 2019, 2:10 PM

#

well, it's happening where when someone else on another computer runs the site, they are getting some of the variables from when I had input data

#

my code is a bit long, I don't mind posting it if necessary

#

but basically the site is taking form input, processing that and building an object of a class

#

and then attributes from that object are being distributed out through a string

#

it's like a madlib, if you're familiar with those

kindred gate Mar 6, 2019, 2:11 PM

#

Maybe you could use some sort of pastebin to send the cod

limber orchid Mar 6, 2019, 2:13 PM

#

ok, give me a min

#

the flask portion of the code: https://pastebin.com/YWYFH9KM
the class "header" (not sure the term with python): https://pastebin.com/P7Dj0sWv

#

also with that header file, it's got a couple very long dictionaries, sorry about that, but obviously they can be ignored

#

actual processing starts around line 262 in that one

limber orchid Mar 6, 2019, 5:28 PM

#

ok well, I still don't know why it should be storing those variables, but it was because of my use of the append method for the list it generates

#

when I switch it to insert, all was fixed

sour turret Mar 6, 2019, 5:31 PM

#

Could someone help me with blueprints in flask? I'm quite new to Python web frameworks and I don't quite understand why it doesn't work. I've looked almost everywhere including docs and stackoverflow, but I am missing something.

inland veldt Mar 6, 2019, 5:37 PM

#

@limber orchid unrelated to your question, but you should really consider using templates for your HTML, especially since you're already using flask.
what are you using to run the site when its not local?

limber orchid Mar 6, 2019, 5:38 PM

#

yeah I just wanted to get up and running without having to learn the whole library.

#

but point taken, for sure

#

I'm using pythonanywhere

inland veldt Mar 6, 2019, 5:43 PM

#

and what's the exact behavior? User1 POSTs to the form, the correct information is returnd. User2 POSTs to the form, and User1's data is returned?

limber orchid Mar 6, 2019, 5:43 PM

#

basically

#

the input calculates some planet placements (it's an astrology madlib toy) and then creates a list of strings based on the placements

#

that list gets returned and the html gets generated with elements from the list placed into that string

#

so, I think it's still taking the input, but because I was using list.append(string) and my output was using constants for the list index, user1's list was being used to populate

#

switching to list.insert(index, string) fixed it

#

but it feels like a bandaid

warm dust Mar 6, 2019, 5:51 PM

I have a Flask page @app.route(/videofeed), which runs a program. It only turns on whenever I access the /videofeed page. The problem is when I close that page, the program still runs in the background. Is it possible for Flask/Nginx/uWSGI to determine that the page was closed and it can now terminate the program?

Hey guys, I'm really struggling to get my flask app deployed to Heroku, I keep getting a cannot parse Procfile error. I've installed gunicorn, my app is in darwinapp.py and in that it's just app = Flask(__name__) so the procfile is just a file (no extension) named Procfile, with a capital P, at the root of my project, with the contents web: gunicorn darwinapp:app

#

Where am I going wrong with this?

#

I'm using a Windows machine, do I have to use Procfile.windows?

what does heroku logs show

junior cloak Mar 7, 2019, 7:51 PM

well that looks like flask is causing the error

#

or gunicorn if youre using that or whatever youre serving it with

#

(i just pinged it as well a couple times)

#

@tacit orbit are you positive the route works locally? just '/' with no path or anything

tacit orbit Mar 7, 2019, 7:54 PM

#

I'm not using gunicorn

#

lemme check that it isn't broken lol

junior cloak Mar 7, 2019, 7:54 PM

#

how are you running the flask app in your Procfile if not gunicorn

stray prism Mar 7, 2019, 7:55 PM

#

@junior cloak I actually managed to get the app running by redoing my Procfile earlier!

tacit orbit Mar 7, 2019, 7:55 PM

#

junior cloak Mar 7, 2019, 7:56 PM

#

@stray prism really? gunicorn has long claimed to have no windows support

tacit orbit Mar 7, 2019, 7:56 PM

#

Looks like we managed to break it. Might be the 0.0.0.0 route

junior cloak Mar 7, 2019, 7:56 PM

#

@tacit orbit you need to make sure its on 0.0.0.0 and binding to the port heroku gives it in the $PORT envvar

#

also you should use gunicorn and not flask.run

#

unless youre just playing around but if 2 people hit the app at once it's going to freak out

tacit orbit Mar 7, 2019, 7:57 PM

#

PORT = int(os.environ.get("PORT",5000))
DEBUG = "NO_DEBUG" not in os.environ

app.run(host="0.0.0.0", port=PORT, debug=DEBUG)

#

mmm okay I'll try setting up gunicorn

junior cloak Mar 7, 2019, 7:58 PM

#

well

#

that shouldnt be causing this issue

#

its just a separate thing

tacit orbit Mar 7, 2019, 7:58 PM

#

Yeah I'll do that later I mean

#

I need to get this deployed by tonight for class

junior cloak Mar 7, 2019, 7:58 PM

does '/' load locally for you for sure

tacit orbit Mar 7, 2019, 7:59 PM

Yeah I don't see flex-wrap working for that.

shrewd sand Mar 7, 2019, 8:05 PM

Ok.

you don't want it to like

If you set the width to a percentage width then you might actually be able to get flex-wrap to work especially if you set the anchors right there with some padding

shrewd sand Mar 7, 2019, 8:09 PM

#

Padding does effect it?

tacit orbit Mar 7, 2019, 8:09 PM

#

It should, yeah

shrewd sand Mar 7, 2019, 8:09 PM

#

But not margin?

tacit orbit Mar 7, 2019, 8:10 PM

#

Margin might

#

but also I'm talking about setting padding for each of the anchors and not for the options container

your app.run() is before all the routes

#

haha

tacit orbit Mar 7, 2019, 8:10 PM

#

Look dude

#

I'm new to this python stuff

#

thanks I'll make that change hopefully it helps!

#

I was treating it like server.listen

junior cloak Mar 7, 2019, 8:11 PM

#

sorry i didnt mean for that to sound insulting it was not

tacit orbit Mar 7, 2019, 8:11 PM

#

in node

#

nah man it didn't you're good!

junior cloak Mar 7, 2019, 8:11 PM

#

where you have at the very bottom the app.run()

#

thats where it belongs

#

you also have it up top though before all the routes

#

have it in one place at the bottom

tacit orbit Mar 7, 2019, 8:12 PM

#

Can I just replace it? paste it over that one?

junior cloak Mar 7, 2019, 8:12 PM

#

python is going to run everything in order unless its inside functions

#

yup

tacit orbit Mar 7, 2019, 8:12 PM

#

sweet

junior cloak Mar 7, 2019, 8:12 PM

#

just replace the app.run(debug=True) with app.run(host="0.0.0.0", port=PORT, debug=DEBUG)

stray prism Mar 7, 2019, 8:13 PM

#

My issue now is that the API token that I've got doesn't seem to be working when I try to access my test page. I've put it into a config var called DARWIN_KEY but it keeps throwing a 500 error code.
Here's my relevant code:

app = Flask(__name__)

DARWIN_KEY = str(os.getenv('SECRET_KEY'))
...
response = requests.get("https://huxley.apphb.com/all/" + str(departure_station) + "/to/" + str(arrival_station) + "/" + str(user_time), params={"accessToken": DARWIN_KEY})

But when I try to access the page I get the following in the traceback:

2019-03-07T20:10:34.195763+00:00 app[web.1]: requests.exceptions.HTTPError: 500 Server Error: Internal Server Error for url: https://huxley.apphb.com/all/tth/to/ecr/['0821',%20'0853',%20'2147']?accessToken=None

#

How do I get my DARWIN_KEY var into the actual code so that it can be used in a request? I originally had it in a separate python file but this isn't the proper way to do things on heroku apparently

tacit orbit Mar 7, 2019, 8:15 PM

#

isn't it os.environ.get

#

PORT = int(os.environ.get("PORT",5000)) is a line I'm using in my app

junior cloak Mar 7, 2019, 8:15 PM

#

you can do efven easier

#

and do os.getenv()

#

but yeah

stray prism Mar 7, 2019, 8:16 PM

#

so no need for the str() either?

junior cloak Mar 7, 2019, 8:16 PM

#

the PORT = and DEBUG = lines are fine

#

just move the app.run() to the bottom and replace the current app.run() line with it

#

oh wait

#

sorry i left for a sec didnt rwealize separate project haha

stray prism Mar 7, 2019, 8:17 PM

#

I'm so sorry lol, I was sitting here waiting for a quiet moment to ask my question lol

junior cloak Mar 7, 2019, 8:17 PM

#

flask is throwing the 500 or that api you are calling

#

print out that url string before you pass it to requests.get

#

make sure its what it should be

#

youre doin ga lot of url + url + url + token etc stuff

#

the issue is clearly with the request itself

stray prism Mar 7, 2019, 8:19 PM

#

oh dammit I pasted in the same code twice, lemme edit

#

There, edited my original question

#

I believe that means that it's seeing the request as having accessToken equal to None?

tacit orbit Mar 7, 2019, 8:22 PM

#

@junior cloak think you can help with getting my db up and running on heroku as well?

#

wait now my app isn't deploying anymore. It says my requirements file is bad

#

I added the marshmallow_sqlalchemy module to requirements.txt and then it wouldn't deploy. I took it off and I'm still getting the same error...

Your a web-dev moving to python. I'm a python dev moving to web-dev xD

tacit orbit Mar 7, 2019, 8:36 PM

#

Put the h2 and a p in a div or something and use display flex, flex-direction column

#

Yeah something like that haha

#

My requirements.txt file is broken now

junior cloak Mar 7, 2019, 8:37 PM

#

@tacit orbit dont add it to requirements.txt. you shouldnt need to ever manually modify requirements.txt

shrewd sand Mar 7, 2019, 8:37 PM

#

OHHHH

#

I'm so bad at not doing that

#

ty!

tacit orbit Mar 7, 2019, 8:37 PM

#

np!

junior cloak Mar 7, 2019, 8:38 PM

#

@tacit orbit are you doing the flask app from inside a virtual environment

tacit orbit Mar 7, 2019, 8:38 PM

#

yeah

shrewd sand Mar 7, 2019, 8:38 PM

#

use docker

junior cloak Mar 7, 2019, 8:38 PM

#

no

#

then pip freeze > requirements.txt is what you do to generate requirements.txt

#

from pip

#

so first just pip install whatever-package-you-need

#

and then freeze it

shrewd sand Mar 7, 2019, 8:39 PM

#

Use pipenv

junior cloak Mar 7, 2019, 8:39 PM

#

the packages will have other dependencies that pip freeze will find

shrewd sand Mar 7, 2019, 8:39 PM

#

The industry standard is pipenv

#

If you want to know more, ill explain

junior cloak Mar 7, 2019, 8:39 PM

#

i use pipenv but at present i'm just trying to help him

#

get the code running

#

he has a deadline and doesnt need to switch all his tooling quite yet

#

but yes, i swear by pipenv

shrewd sand Mar 7, 2019, 8:40 PM

#

Shame pipenv in docker is not great

junior cloak Mar 7, 2019, 8:41 PM

#

docker pull kennethreitz/pipenv

#

works just fine

tacit orbit Mar 7, 2019, 8:41 PM

#

So I just did that and it's not working still

junior cloak Mar 7, 2019, 8:41 PM

#

does it run locally or not

tacit orbit Mar 7, 2019, 8:41 PM

#

I was going to try reverting to a previous commit but I don't know how to do that

shrewd sand Mar 7, 2019, 8:41 PM

#

@junior cloak its so slow

tacit orbit Mar 7, 2019, 8:41 PM

#

it does

junior cloak Mar 7, 2019, 8:41 PM

#

@tacit orbit what is the error? and does it run locally? you should not need to revert

#

just post the error

tacit orbit Mar 7, 2019, 8:41 PM

#

it runs locally

junior cloak Mar 7, 2019, 8:42 PM

#

post the heroku error

tacit orbit Mar 7, 2019, 8:42 PM

#

oof greater than 2k character

junior cloak Mar 7, 2019, 8:42 PM

#

@shrewd sand do you normally use the alpine images or something? the pipenv image is based off the full debian python image

#

junior cloak Mar 7, 2019, 8:43 PM

#

@brave karma i like smaller images as well so even then my dockerfile to bootstrap a pipenv project is like 5 lines

shrewd sand Mar 7, 2019, 8:43 PM

#

@junior cloak i did not think of that...

#

use a debian image

#

It might be faster

#

Interesting

junior cloak Mar 7, 2019, 8:44 PM

#

no the pipenv image is the debian image

#

i just dont know what you mean by "slow"

#

other than everything in docker is going to be slower a bit than non-docker

#

and if you are on a mac or windows even more so

#

@tacit orbit there is some problem with that package, bonjour-py==0.3. i cant install it either. do you know why it's in your requirements?

#

@tacit orbit please pastebin the requirements.txt

tacit orbit Mar 7, 2019, 8:45 PM

#

no idea

junior cloak Mar 7, 2019, 8:45 PM

#

this soudns like maybe its not using your venv packages

#

but your system ones

tacit orbit Mar 7, 2019, 8:46 PM

#

my requirements went from like 10 lines to 66

brave karma Mar 7, 2019, 8:46 PM

#

What

junior cloak Mar 7, 2019, 8:46 PM

#

okay so you probabbly were not using the virtual environment

tacit orbit Mar 7, 2019, 8:46 PM

#

I'm in my venv

junior cloak Mar 7, 2019, 8:46 PM

#

@brave karma sorry wrong tag

brave karma Mar 7, 2019, 8:46 PM

#

Oh u meant the other guy

junior cloak Mar 7, 2019, 8:46 PM

#

yeah sorry

brave karma Mar 7, 2019, 8:46 PM

#

np

junior cloak Mar 7, 2019, 8:46 PM

#

@tacit orbit "in it" as in in the folder, or you sourced the venv activate script

tacit orbit Mar 7, 2019, 8:46 PM

#

I sourced the activate script

#

I'm in my root

junior cloak Mar 7, 2019, 8:47 PM

#

what does it say in the terminal if you do which pip

tacit orbit Mar 7, 2019, 8:47 PM

#

/usr/local/bin/pip

junior cloak Mar 7, 2019, 8:47 PM

#

... yeah i think something is up with your shell

#

that is not the venv pip

#

what about which python

tacit orbit Mar 7, 2019, 8:48 PM

#

/usr/bin/python

junior cloak Mar 7, 2019, 8:48 PM

#

yeah those are both system versions

#

not the virtualenv versions

#

so your requirements.txt has your system packages in it

tacit orbit Mar 7, 2019, 8:48 PM

#

weird

#

oh wait when we generated the requirements file before I think we did like pip freeze -r > requirements.txt

#

or something

junior cloak Mar 7, 2019, 8:49 PM

#

yes exactly

#

you needed to be inside the venv when you ran that

tacit orbit Mar 7, 2019, 8:49 PM

#

not the folder venv right?

junior cloak Mar 7, 2019, 8:49 PM

#

not sure why your shell is being weird, but in the meantime you can run it manually

#

nah

tacit orbit Mar 7, 2019, 8:49 PM

#

kk

#

so I ran it and it said it needs an arg

junior cloak Mar 7, 2019, 8:50 PM

#

oh

#

no -r sorfry

#

just pip freeze > requirements.txt

tacit orbit Mar 7, 2019, 8:50 PM

#

yeah that gave me all the system files

junior cloak Mar 7, 2019, 8:50 PM

#

not from inside the venv folder but with the venv sourced

#

yeah.

#

so your venv is not working basically.

tacit orbit Mar 7, 2019, 8:50 PM

#

fun times T_T

junior cloak Mar 7, 2019, 8:50 PM

#

so heres what you can do first

#

before fixing that

#

wherever the venv folder is actually, you can run pip manually because its copy lives in theres

#

venv/bin/pip

#

replace venv with path of the actual venv

tacit orbit Mar 7, 2019, 8:51 PM

#

do I source it?

junior cloak Mar 7, 2019, 8:51 PM

#

no just replace the pip command with it. like

#

so see what venv/bin/pip freeze > requirements.txt does

#

sourcing the venv is just a shortcut for that

#

it is suppposed to replace python with the one in side the venv bin folder. same with pip

tacit orbit Mar 7, 2019, 8:52 PM

#

no such file or directory

junior cloak Mar 7, 2019, 8:52 PM

#

what is the path you are giving it

#

take out 'venv' and replace it with the path to the actual folder were you put the virtualenv

tacit orbit Mar 7, 2019, 8:55 PM

#

from system root or the root directory of the project

#

like

#

the venv is literally just in my project

#

I've tried both btw

junior cloak Mar 7, 2019, 8:56 PM

#

what is the name of the venv in your project root

#

the folder

#

venv or something else

tacit orbit Mar 7, 2019, 8:56 PM

#

venv

junior cloak Mar 7, 2019, 8:58 PM

#

if you have this command, pastebiin the output of tree -faL 3

#

or paste here

#

from inside your project root

#

where you think the venv is

tacit orbit Mar 7, 2019, 8:58 PM

#

no dice 😦

junior cloak Mar 7, 2019, 8:58 PM

#

great. okay well

tacit orbit Mar 7, 2019, 8:59 PM

#

lol...

junior cloak Mar 7, 2019, 8:59 PM

#

then ls venv

#

ls venv/bin

#

if your venv is there and working, it has a bin folder

tacit orbit Mar 7, 2019, 8:59 PM

#

yeah

junior cloak Mar 7, 2019, 8:59 PM

#

and inside the bin folder is python and pip

tacit orbit Mar 7, 2019, 8:59 PM

#

yup

junior cloak Mar 7, 2019, 8:59 PM

#

this is correct?

tacit orbit Mar 7, 2019, 8:59 PM

#

yes

junior cloak Mar 7, 2019, 9:00 PM

#

then just running venv/bin/pip should work from there

#

or ./venv/bin/pip

tacit orbit Mar 7, 2019, 9:00 PM

#

no such file or directory

#

(venv) ryanMatthews (ryan-matthews *) labspt2-scratch-and-map $ ./venv/bin/pip
-bash: ./venv/bin/pip: /Users/ryanMatthews/Desktop/lambdaSchool/labspt2-scratch-and-map/scratch-and-m: bad interpreter: No such file or directory

junior cloak Mar 7, 2019, 9:01 PM

#

bad interpreter

#

okay so your virtual environment isjust kind of screwed basically

#

haha

tacit orbit Mar 7, 2019, 9:01 PM

#

tada

junior cloak Mar 7, 2019, 9:01 PM

#

its fine we can fix this quickly

#

but it makse the other stuff make sense

tacit orbit Mar 7, 2019, 9:01 PM

#

Thanks so much for the help my dude

#

We've been taught a lot of stuff but we haven't been taught anything about python and I was like "yo lets use python/flask for our backend since it would look really good on our resumes to be like we learned this in 10 weeks for a fully functional app"

junior cloak Mar 7, 2019, 9:02 PM

#

one sec

tacit orbit Mar 7, 2019, 9:02 PM

#

biting me in the ass

junior cloak Mar 7, 2019, 9:03 PM

#

@tacit orbit go to #help-croissant

#

we can step off here

stray prism Mar 7, 2019, 9:43 PM

#

So I've tested my original flask app, and the jsonToken variable seems to be working fine

#

For some reason, I can't get the key working as a var in heroku itself it seems

#

To reiterate: I've got my API token set as DARWIN_KEY config variable as such:

app = Flask(__name__)

DARWIN_KEY = os.getenv('SECRET_KEY')

Here is my request:

response = requests.get("https://huxley.apphb.com/all/" + str(departure_station) + "/to/" + str(arrival_station) + "/" + str(user_time), params={"accessToken": DARWIN_KEY})

But I keep getting the following error:

2019-03-07T20:10:34.195763+00:00 app[web.1]: requests.exceptions.HTTPError: 500 Server Error: Internal Server Error for url: https://huxley.apphb.com/all/tth/to/ecr/['0821',%20'0853',%20'2147']?accessToken=None

#

But the request itself is fine when I test it in flask itself

orchid aspen Mar 8, 2019, 1:35 AM

#

can someone tell me why this doesn't work ```@app.route('/youtube-dl/q', methods=['GET'])
def q_size():
content = {"success": True, "size": json.dumps(list(dl_q.queue))}
return jsonify(content)

#

because it returns this

#

  "size": "[[\"https://www.youtube.com/watch?v=2B6UvU-B7X4\", {\"format\": \"bestvideo\"}], [\"https://www.youtube.com/watch?v=5mejPwXXAdk\", {\"format\": \"bestvideo\"}], [\"https://www.youtube.com/watch?v=5mejPwXXAdk\", {\"format\": \"bestvideo\"}], [\"https://www.youtube.com/watch?v=5mejPwXXAdk\", {\"format\": \"bestvideo\"}]]", 
  "success": true
}```

junior cloak Mar 8, 2019, 3:08 AM

#

@orchid aspen do you just mean the ugly formatting?

#

on line 3, you are turning the size stuff into json

#

and then on line 4 youre doing it again

python vs js for web dev

fathom prism Mar 8, 2019, 8:35 AM

#

Why not both?

devout nebula Mar 8, 2019, 8:36 AM

#

Yeah, I'm taking a course on udemy right now that will teach me both.... but its going to focus on python and django.

#

was just curious why is java more popular?

fathom prism Mar 8, 2019, 8:36 AM

#

Java or JS?

devout nebula Mar 8, 2019, 8:36 AM

#

sorry JS is mainly used for web dev yes?

fathom prism Mar 8, 2019, 8:37 AM

#

Correct. It’s popular because it’s kind of the only language of the browser at the moment

#

You can get by without it using only markups like html but to add interactions you’ll need JavaScript

#

So instead of JavaScript vs python it’s more of should I use JavaScript in my web project since they’re sort of unrelated

devout nebula Mar 8, 2019, 8:39 AM

#

I see, so Javascript is whats used for user accessibility
