The thing is that it works as in it adds a new app with my user information

#

Instead of registering it into the contrib.auth app

#

I'm just gonna use this as a separate app called user and put my models in another app and just remove the Group all together

native tide Jun 20, 2018, 4:30 PM

#

did you migrate when you set AUTH_USER_MODEL?

brittle copper Jun 20, 2018, 4:30 PM

#

I deleted the database

#

And did my first migration with auth user set

#

Yup went with that

#

Thank you for trying tho :D

#

I installed Django because it was bugging me. Couldn't get it to work :D

#

one possible solution might be templates

gritty carbon Jun 20, 2018, 5:38 PM

#

Hey guys, any suggestion for good and free course and/or tutorial for Django? I'm doing one from official site at this moment, but i could use something more detailed and begginer friendly 😃

meager anchor Jun 20, 2018, 5:45 PM

#

I found the one on the site to be pretty detailed..

#

@gritty carbon what issues did you face when reading through it?

gritty carbon Jun 20, 2018, 7:44 PM

#

@stone vine thanks mate will check them out for sure
@meager anchor i don't understand templates syntax and why we are passing values to them in form of dictionary, that's the first thing for example. I have no problem recreating steps in that tutorial but i don't feel that i'm really understanding all concepts

meager anchor Jun 20, 2018, 7:44 PM

#

Templates get values in dictionaries because that's the simplest way to associate a variable in the template with a value from your python code

Hello fellas. I am in need of some asistance with SOAP ws and python. If someone knows anything about it, please, would you kindly help me? This is my case.

#

I'm trying to send an XML envelope file to a SOAP WS using python

#

Notice that the WS i want to consume is public and has the following tree structure.

#

📎 unknown.png

#

So i just want to consume the sendBill method from that WS

#

for this i have tried about 3 different libraries. Being zeep the most recommended on StackOverflow and the one that looks like might solve my problem.

#

But with zeep, it looks like all i need to do is sent the variables to the parameters the method requires. Which is actually wrong, since the XML envelope you get when analyzing that public ws looks like this.

#

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://service.sunat.gob.pe">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:sendBill>
         <!--Optional:-->
         <fileName>?</fileName>
         <!--Optional:-->
         <contentFile>cid:872654575379</contentFile>
         <!--Optional:-->
         <partyType>?</partyType>
      </ser:sendBill>
   </soapenv:Body>
</soapenv:Envelope>

#

but the ws actually wants a xml like this

#

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ser="http://service.sunat.gob.pe" xmlns:wsse="http://docs.oasisopen.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
    <soapenv:Header>
        <wsse:Security>
            <wsse:UsernameToken>
                <wsse:Username>20100066603MODDATOS</wsse:Username>
                <wsse:Password>moddatos</wsse:Password>
            </wsse:UsernameToken>
        </wsse:Security>
    </soapenv:Header>
    <soapenv:Body>
        <ser:sendBill>
            <fileName>20100066603-01-F001-1.zip</fileName>
            <contentFile>my-zip-file-encoded-base64</contentFile>
        </ser:sendBill>
    </soapenv:Body>
</soapenv:Envelope>

#

so i need to send an entirely XML to that ws instead of just filling the parameters from the method i want to use

#

for that i have found this example (from StackOverflow) on python

#

import requests
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
#headers = {'content-type': 'application/soap+xml'}
headers = {'content-type': 'text/xml'}
body = """<?xml version="1.0" encoding="UTF-8"?>
         <SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" 
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
            <SOAP-ENV:Header/>
              <ns1:Body><ns0:GetWeatherInformation/></ns1:Body>
         </SOAP-ENV:Envelope>"""

response = requests.post(url,data=body,headers=headers)
print response.content

#

the thing now is. How do i select the method i want to use from the WS i want to consume?

#

Btw i am using python 3. Not python 2.

#

If i adapt that example to my case, i would get something like this

import requests
url = 'https://e-beta.sunat.gob.pe/ol-ti-itcpfegem-beta/billService?wsdl'
# headers = {'content-type': 'text/xml'} if needed
headers = {'content-type': 'application/soap+xml'}
body = """<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ser="http://service.sunat.gob.pe" xmlns:wsse="http://docs.oasisopen.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<soapenv:Header>
<wsse:Security>
<wsse:UsernameToken>
<wsse:Username>20100066603MODDATOS</wsse:Username>
<wsse:Password>moddatos</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
</soapenv:Header>
<soapenv:Body>
<ser:sendBill>
<fileName>20100066603-01-F001-1.zip</fileName>
<contentFile>my-file-encoded-on-base64</contentFile>
</ser:sendBill>
</soapenv:Body>
</soapenv:Envelope>
"""

response = requests.post(url, data=body, headers=headers)
print(response.content)

#

still tho, how do i select the method i want to use?

native tide Jun 21, 2018, 7:11 PM

#

(don't know much about SOAP), but I'd take a look at zeep again

#

I'd be surprised if it can't do what you need

#

how did you get zeep's xml? with create_message?

boreal tree Jun 21, 2018, 7:13 PM

#

sadly i don't seem to find it. So i'm asking every where if someone could help me.

native tide Jun 21, 2018, 7:14 PM

#

you can't find the generated xml?

boreal tree Jun 21, 2018, 7:15 PM

#

No, i used requests on the second example

native tide Jun 21, 2018, 7:15 PM

#

http://python-zeep.readthedocs.io/en/master/client.html#creating-the-raw-xml-documents

#

this helps?

boreal tree Jun 21, 2018, 7:16 PM

#

sadly, no. That's for creating the XML

#

i already did that

#

i have an xml created

#

i want to send it to a SOAP ws

#

but i want to send it to an specific method inside that ws

native tide Jun 21, 2018, 7:17 PM

#

by using requests or zeep?

boreal tree Jun 21, 2018, 7:17 PM

#

any of them would be useful

#

or any other library

#

😛

native tide Jun 21, 2018, 7:18 PM

#

have you tried sending the xml with requests with a POST request like this:

#

https://stackoverflow.com/questions/18175489/sending-soap-request-using-python-requests

Stack Overflow

Sending SOAP request using Python Requests

Is it possible to use Python's requests library to send a SOAP request?

#

(I'd still probably go back to zeep if this isn't working out)

boreal tree Jun 21, 2018, 7:21 PM

#

yeah, that's the same example i wanted to use. But, how do i define the method i want to use from the ws?

native tide Jun 21, 2018, 7:25 PM

#

guessing, but isn't the method defined somewhere in this url: url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"?

#

maybe Weather.asmx? ?

boreal tree Jun 21, 2018, 7:27 PM

#

wait is it? let me see

native tide Jun 21, 2018, 7:30 PM

#

or if you try something like this:
"For example, suppose the StockServices Web service from the preceding procedure contains a Web service method called GetQuote; the Web service method accepts a stock symbol as a parameter, returning the price as a double-precision floating-point number. Enter the following HTTP-GET request in the browser's address bar to test this method:

http://<servername>/apppath/StockServices.asmx/GetStockQuote?tickerName=MSFT "

#

so instead of GetStockQuote you'd try sendBill

#

you said you tried this: https://e-beta.sunat.gob.pe/ol-ti-itcpfegem-beta/billService?wsdl but it didn't work

#

was there some kind of error in the response?

#

oh that's only a service

#

https://e-beta.sunat.gob.pe/ol-ti-itcpfegem-beta/billService?sendBill
https://e-beta.sunat.gob.pe/ol-ti-itcpfegem-beta/billService?sendBill?wsdl

#

I'd try this then

#

and if this doesn't work, I'd go back to zeep :D

boreal tree Jun 21, 2018, 7:39 PM

#

D:

#

a friend of mine helped me and said he would do this on zeep

import zeep
from zeep.wsse.username import UsernameToken

import base64

with open("20100066603-01-F001-1.zip", "rb") as f:
    bytes = f.read()
    encoded = base64.b64encode(bytes)

wsdl = 'https://e-beta.sunat.gob.pe/ol-ti-itcpfegem-beta/billService?wsdl'
client = zeep.Client(wsdl=wsdl, wsse=UsernameToken('20100066603MODDATOS', 'moddatos'))
print(client.service.sendBill('20100066603-01-F001-1.zip', b'encoded'))

#

But it doesn't return the same error as when sending the same data with SOAPUI

#

so, it is not working correctly.

#

but with that, at least i now know how to call an specific method.

native tide Jun 21, 2018, 7:45 PM

#

what does this print: print(client.service.sendBill('20100066603-01-F001-1.zip', b'encoded')) ?

boreal tree Jun 21, 2018, 7:45 PM

#

Just a reminder. That all data i've been using is for testing. It is suppoused to give an error, but it is supposed to give the same error on SOAP Ui as on the IDE i'm using. (which is PyCharm)

native tide Jun 21, 2018, 7:45 PM

#

hmm

#

:D

boreal tree Jun 21, 2018, 7:45 PM

#

that prints this

#

zeep.exceptions.Fault: El archivo ZIP no contiene comprobantes - Detalle: xxx.xxx.xxx value='ticket: 1529609364082 error: Validation File count error'

native tide Jun 21, 2018, 7:46 PM

#

just so I understand. you get the correct error on SOAP Ui?

boreal tree Jun 21, 2018, 7:46 PM

#

and SOAPUI prints this

<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">

         <faultstring>El documento electrónico ingresado ha sido alterado - Detalle: Incorrect reference digest value</faultstring>
      </soap-env:Fault>
   </soap-env:Body>
</soap-env:Envelope>

#

yeah i get the error i was expecting on SOAP UI

#

but not on PyCharm.

native tide Jun 21, 2018, 7:48 PM

#

do you also send the zip file via SOAP Ui?

boreal tree Jun 21, 2018, 7:50 PM

#

yep

#

encoded on base64

#

SOAP UI gives you that option, which is what i also need to do.

native tide Jun 21, 2018, 7:54 PM

#

where can I see the arguments sendBill requires?

boreal tree Jun 21, 2018, 7:55 PM

#

If you need more details, just tell me. I'm can give you as much info as i am able to.

#

that's on the documentation for that ws

#

it's like this

#

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ser="http://service.sunat.gob.pe" xmlns:wsse="http://docs.oasisopen.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
    <soapenv:Header>
        <wsse:Security>
            <wsse:UsernameToken>
                <wsse:Username>20100066603MODDATOS</wsse:Username>
                <wsse:Password>moddatos</wsse:Password>
            </wsse:UsernameToken>
        </wsse:Security>
    </soapenv:Header>
    <soapenv:Body>
        <ser:sendBill>
            <fileName>20100066603-01-F001-1.zip</fileName>
            <contentFile>my-zip-file-encoded-base64</contentFile>
        </ser:sendBill>
    </soapenv:Body>
</soapenv:Envelope>

#

and not like the one you can get by inserting that ws on SOAPUI

#

according to the documentation

#

http://contenido.app.sunat.gob.pe/insc/ComprobantesDePago+Electronicos/manual-programador-setiembre-2016.pdf

#

it's on spanish. But the example for using that ws is on page 17

#

📎 unknown.png

native tide Jun 21, 2018, 8:05 PM

#

how do you run this code?

boreal tree Jun 21, 2018, 8:05 PM

#

the given example on the documentation?

native tide Jun 21, 2018, 8:06 PM

#

no, yours with zeep

boreal tree Jun 21, 2018, 8:06 PM

#

i run it on PyCharm

native tide Jun 21, 2018, 8:06 PM

#

if you comment out the print line, do you get any errors?

boreal tree Jun 21, 2018, 8:07 PM

#

nope

#

😮

native tide Jun 21, 2018, 8:08 PM

#

what's in that zip file?

boreal tree Jun 21, 2018, 8:08 PM

#

an xml

#

with test data. Not real

#

Do you want it? I just adapted it from another example on of the example given on the documentation

native tide Jun 21, 2018, 8:09 PM

#

is it large?

boreal tree Jun 21, 2018, 8:10 PM

#

hmmm about 320 lines of xml code

native tide Jun 21, 2018, 8:10 PM

#

are there many tickets?

boreal tree Jun 21, 2018, 8:10 PM

#

hmmm... what are tickets? 😛

native tide Jun 21, 2018, 8:12 PM

#

don't really know. I assumed you have them defined in your zip file, because 'ticket' is mentioned in the error

#

can you add this line after your print:
import sys;sys.exit()

#

and paste if there are any errors

boreal tree Jun 21, 2018, 8:20 PM

#

like this?

#

📎 unknown.png

native tide Jun 21, 2018, 8:21 PM

#

yeah

boreal tree Jun 21, 2018, 8:21 PM

#

still, it's not reading what's inside my zip

native tide Jun 21, 2018, 8:22 PM

#

yeah, but are there any errors?

boreal tree Jun 21, 2018, 8:22 PM

#

📎 unknown.png

native tide Jun 21, 2018, 8:22 PM

#

no other errors?

boreal tree Jun 21, 2018, 8:23 PM

#

nope

#

i just undertood the problem itslef

#

the ws is not reading the zip file

#

or what's inside the zipfile

#

but that's what's strange, i tecnically am doing the same thing on SOAPUI and it works

native tide Jun 21, 2018, 8:25 PM

#

is your zip file and your file with the code in the same directory?

boreal tree Jun 21, 2018, 8:25 PM

#

yeah

#

📎 unknown.png

native tide Jun 21, 2018, 8:26 PM

#

oh

#

can you try:

print(client.service.sendBill('20100066603-01-F001-1.zip', encoded))

insted of:

print(client.service.sendBill('20100066603-01-F001-1.zip', b'encoded'))

#

(and delete sys stuff)

boreal tree Jun 21, 2018, 8:27 PM

#

ok

#

same error

#

📎 unknown.png

native tide Jun 21, 2018, 8:31 PM

#

just to be sure, rename the bytes variable. it's a reserved keyword in python and it shouldn't be used as a name (though, it's not likely it's causing errors in this case)

#

rename to to something like: zip_bytes or anything you like

#

I'd try adding this to the code:

from zeep import Client, Settings

settings = Setting(strict=False, xml_huge_tree=True)
client = Client([what_you_have_now], settings=settings)

#

after that I'm running out of ideas unfortunately

#

@boreal tree, also make sure you have the username and the password in the correct order (and you've posted the username and the password several times, I'd urge you to change the password at least)

boreal tree Jun 21, 2018, 9:27 PM

#

I'm sorry i didn't respond, i was absent. The username and password are test data, is not real, i put random numbers to match an example just like it is on its public documentation.

#

As i said before, the xml has test data and it's supposed to return an error on the ws. My goal is to have the same error on Pycharm. That's how i will know i could send data correctly.

native tide Jun 21, 2018, 9:29 PM

#

ok

#

so one last thing I would try is with settings

boreal tree Jun 21, 2018, 9:30 PM

#

i am currently trying that.

native tide Jun 21, 2018, 9:30 PM

#

hope it works, because beyond that... no idea :=)

boreal tree Jun 21, 2018, 9:34 PM

#

Thank you so much for your help @native tide I know you must be tired of helping me but sadly it did not fixed the problem.

On the other hand. I wonder if print is the best way to get the response form the ws. Maybe the problem is the way i want to retrieve the data?

native tide Jun 21, 2018, 9:34 PM

#

it's not a problem :)

boreal tree Jun 21, 2018, 9:34 PM

#

📎 unknown.png

native tide Jun 21, 2018, 9:34 PM

#

the print here in this case doesn't matter

#

it's just there to show you the response

boreal tree Jun 21, 2018, 9:35 PM

#

i get the same error message.

zeep.exceptions.Fault: El archivo ZIP no contiene comprobantes - Detalle: xxx.xxx.xxx value='ticket: 1529616712333 error: Validation File count error'

#

which is a response the ws is giving me

native tide Jun 21, 2018, 9:36 PM

#

I think this is the same error as before, right?

boreal tree Jun 21, 2018, 9:36 PM

#

it says the zip cannot be validated

#

yeah

#

it's the same error

native tide Jun 21, 2018, 9:36 PM

#

in SOAP Ui, do you have everything on one screen?

boreal tree Jun 21, 2018, 9:37 PM

#

yep

native tide Jun 21, 2018, 9:37 PM

#

can you screenshot it and show me?

boreal tree Jun 21, 2018, 9:37 PM

#

you mean this?

📎 unknown.png

#

the value on content file is not what i sent

#

i wrote that so it could be understandable

#

lol

native tide Jun 21, 2018, 9:39 PM

#

the value of content value is base64 encoded gibberish?

boreal tree Jun 21, 2018, 9:39 PM

#

what i actualy do is, right click on that field, then "insert data as base64" then select the .zip i need to sent

native tide Jun 21, 2018, 9:39 PM

#

ok

boreal tree Jun 21, 2018, 9:39 PM

#

you can try it yourself if you have soapui

#

do you want the .zip?

#

its an xml adapted from an example on the ws documentation

#

with fictional data

#

that's why it returns an error, but it returns an error of "invalid value"

#

i expect to have the same error on PyCharm

#

but can't have it

#

:/

native tide Jun 21, 2018, 9:40 PM

#

can you paste the faultstring on the right?

#

yeah, because the error you are seeing in pycharm is not the response

now I'm analyzing both base 64 array bit. to see if maybe both are different.

#

the one generated with SOAPui and the other generated by script

boreal tree Jun 22, 2018, 6:38 PM

#

i'm using the following code in order to get the base64 code i'm sending to that ws

from zeep import Client, Settings
from zeep.wsse.username import UsernameToken

import base64

with open("20100066603-01-F001-1.zip", "rb") as f:
    bytes = f.read()
    encoded = base64.b64encode(bytes)
settings = Settings(strict=False, xml_huge_tree=True)
wsdl = 'https://e-beta.sunat.gob.pe/ol-ti-itcpfegem-beta/billService?wsdl'
client = Client(wsdl=wsdl, wsse=UsernameToken('20100066603MODDATOS', 'moddatos'), settings=settings)
# print(client.service.sendBill('20100066603-01-F001-1.zip', b'encoded'))
# print(client.service.sendBill('20100066603-01-F001-1.zip', encoded))
print(encoded)

#

it prints this

b'UEsDBBQAAAAAAJB71UykoJUx5j4AAOY+AAAZAA...AEcAAAAdPwAAAAA='

#

while SoapUIs converter just returns this after generating the base64 code

#

UEsDBBQAAAAAAJB71UykoJUx5j4AAOY+AAAZAA...AEcAAAAdPwAAAAA=

#

Isn't the b' affecting the base64 code in any way?

native tide Jun 22, 2018, 6:40 PM

#

b'' is a Python thing, I think

#

I'd say those are the same

boreal tree Jun 22, 2018, 6:41 PM

#

yeah i checked. Both codes are literrally the same

#

except for the b' at the begining and the ' at the end

native tide Jun 22, 2018, 6:43 PM

#

b'' indicates that its bytes

polar wasp Jun 22, 2018, 6:44 PM

#

just do print(encoded.decode()) # which looks kind of nonsensical, but what's being "decoded" here is ASCII

#

I've actually always been kind of annoyed by the fact that b64encode returns bytes instead of a string

boreal tree Jun 22, 2018, 6:52 PM

#

you mean like this?

#

📎 unknown.png

native tide Jun 22, 2018, 6:53 PM

#

its .decode()

boreal tree Jun 22, 2018, 6:53 PM

#

oops 😛

#

ohh i see

#

now it returns the same as on soapUI

#

i'll try and see if that works

#

sigh*

#

it indeed want a byte-like type 😦

#

📎 unknown.png

#

So, my concusion is that, the problem is not the encoding of my .zip on base 64. I'll be back on the previous error for now and keep on looking for solutions.

#

📎 unknown.png

boreal tree Jun 22, 2018, 7:24 PM

#

Ok,I found out 1 guy had the same problem. But he says he resolved it cuz the encoding of the zip was actually just econding the xml inside the .zip .Would this be the case for my problem as well? Does the encode method from base64 bypass the .zip and just encode the .XML? Does anyone know something about it?

#

if so, then why was the base64 code generated on SoapUI the same base64 code i got, generated on Python?

native tide Jun 22, 2018, 7:26 PM

#

you can try it out

#

just unzip the file and encode it

#

I don't think it bypassess the zip

brittle copper Jun 22, 2018, 7:29 PM

#

Lemme ask you guys something @brave mantle and @deep cave You guys are the only prof python devs I know

#

And you roughly know what I can and can't write

#

And I thought I was in off topic god damn it

#

I was gonna ask if I'd have any chance at a python webdev job with my current skills

brave mantle Jun 22, 2018, 7:33 PM

#

@brittle copper maybe

#

depends how much on-the-job training they'd provide

brittle copper Jun 22, 2018, 7:34 PM

#

So at most I can be an intern?

#

Kind of

deep cave Jun 22, 2018, 7:37 PM

#

get better at working with others, and focus on readability. you probably have the skills to solve python webdev problems but you lack essential teamwork and readability skills.

#

being able to solve the problems is really the easy part.

brittle copper Jun 22, 2018, 7:38 PM

#

I mean I just am memimg around when I write code but I think I can write readable code

#

I mean at least I think so

deep cave Jun 22, 2018, 7:38 PM

#

probably. it's not rocket science

#

just following best practice and style rules.

#

but do more collab. with flake8.

#

and uh

brittle copper Jun 22, 2018, 7:39 PM

#

Hmm, I'm gonna actually try to finish a full project and put it on github and apply to a couple entry level jobs

deep cave Jun 22, 2018, 7:39 PM

#

another tip

#

python webdev is often full stack-y

#

get over your fear of linux.

#

work with databases

#

master git

brittle copper Jun 22, 2018, 7:40 PM

#

Yeah I can handle basic javascript and html and I am okay as long as there is an ORM for the database

deep cave Jun 22, 2018, 7:40 PM

#

don't expect an ORM

brittle copper Jun 22, 2018, 7:40 PM

#

Git, I'm still learning

deep cave Jun 22, 2018, 7:40 PM

#

learn sql

brittle copper Jun 22, 2018, 7:40 PM

#

Linux is just too scary to dive into

#

Dql? Is that like a database?

#

Oh

#

xD

deep cave Jun 22, 2018, 7:41 PM

#

sorry. mobile.

brave mantle Jun 22, 2018, 7:41 PM

#

linux isn't scary

brittle copper Jun 22, 2018, 7:41 PM

#

dw :3

brave mantle Jun 22, 2018, 7:41 PM

#

for web work, it's often less scary than everything else

brittle copper Jun 22, 2018, 7:41 PM

#

There are just so many of them

deep cave Jun 22, 2018, 7:41 PM

#

you don't need to learn them all

#

just learn one well enough to be comfortable.

brave mantle Jun 22, 2018, 7:41 PM

#

learn a debian, learn a red hat

#

that's about it

deep cave Jun 22, 2018, 7:42 PM

#

get a vps or something with like centos or ubuntu server and put up shit on it

brittle copper Jun 22, 2018, 7:42 PM

#

learn the debian

#

Or a debian based one?

#

Like would ubuntu do it? xD

meager anchor Jun 22, 2018, 7:42 PM

#

my server runs ubuntu, and i've learnt a lot from it

#

ubuntu is debian based

brittle copper Jun 22, 2018, 7:42 PM

#

Oh so just ubuntu is okay, nice :D

#

get a vps or something

#

Imma try AWS

#

I'm just too scared

#

xD

deep cave Jun 22, 2018, 7:43 PM

#

fuck aws

brittle copper Jun 22, 2018, 7:43 PM

#

lol why

deep cave Jun 22, 2018, 7:43 PM

#

or.. I mean.. it's a valuable tool

#

but it's a terrible vps choice for a beginner

boreal tree Jun 22, 2018, 7:43 PM

#

so, in theory, by doing this, i am encoding my .xml instead of my .zip, which i can confirm that happening since the base64 code is different from before. But i still get the same error. @native tide

from zeep import Client, Settings
from zeep.wsse.username import UsernameToken

brittle copper Jun 22, 2018, 7:43 PM

#

Oh

deep cave Jun 22, 2018, 7:43 PM

#

digitalocean or scaleway would be much better.

brittle copper Jun 22, 2018, 7:44 PM

#

Hmm, welp I'll try to do it that way then I mean aren't the commands and stuff the same

#

Since it is the same linux distro

deep cave Jun 22, 2018, 7:44 PM

#

scaleway has a 2 euro vps which is quite powerful.

#

2 euros per month

brittle copper Jun 22, 2018, 7:45 PM

#

Yeah that's not a problem

#

But aren't they the same as long as they use the same linux distro inside

deep cave Jun 22, 2018, 7:45 PM

#

yes, mostly

#

package manager and file locations vary

brittle copper Jun 22, 2018, 7:45 PM

#

Like don't they work like I have a remote computer and put my os in it and do whatever I want

deep cave Jun 22, 2018, 7:45 PM

#

and the internal workings

#

but just like with programming languages - learn one and the rest are easy

brittle copper Jun 22, 2018, 7:46 PM

#

Nice

#

Welp I still have to finish a project to show at applications to prove that I actually learn stuff but I'm definitely gonna try my chances :3

deep cave Jun 22, 2018, 7:47 PM

#

yeah, you should bring a github with something on it

#

it's a huge advantage over those who do not.

#

and you know, once you start fucking with a VPS you can suddenly pick up 20 of those buzzwords in a year

brittle copper Jun 22, 2018, 7:48 PM

#

I am already probably gonna ask a ton of stuff when I am actually gonna deploy my very first website

#

I only ever used py manage.py runserver

#

lol

deep cave Jun 22, 2018, 7:49 PM

#

soon you'll be able to say you know about nginx, gunicorn, postgresql and rethinkdb, you know ubuntu server and systemd and you know travis-ci and github or gitlab and ci-runners and you know linters and you know the basics of a bash script and before you know it, you're one of those guys with a list of tech on their resume

brittle copper Jun 22, 2018, 7:49 PM

#

Okay I've almost heard all of them

#

Except ci-runners

deep cave Jun 22, 2018, 7:50 PM

#

it's just travis on gitlab

#

basically

#

📎 unknown.png

brittle copper Jun 22, 2018, 7:50 PM

#

Oh, okay I've heard almost all of them :D

#

Nice

deep cave Jun 22, 2018, 7:50 PM

#

I put one of these stupid lists on my resume

#

and people eat that shit up

brittle copper Jun 22, 2018, 7:50 PM

#

Oh damn xD

#

Okay I know js, python, django, jinja

#

Nice

#

xD

deep cave Jun 22, 2018, 7:51 PM

#

so what you want is just a project on github / gitlab that showcases these techs. then when you brag about knowing all this shit in an interview, you can actually back it up with a URL that shows you used them in a project.

#

even if it's a stupid project

strange thorn Jun 22, 2018, 7:51 PM

#

can i say i know LLVm when i have written a hello world in LLVM?

deep cave Jun 22, 2018, 7:52 PM

#

you could, but I don't know if you should :P

strange thorn Jun 22, 2018, 7:52 PM

#

k

brittle copper Jun 22, 2018, 7:52 PM

#

I mean I had a working website already but I avoided putting it on github

#

And am rewriting it

#

With proper tools

deep cave Jun 22, 2018, 7:52 PM

#

I make it a point to only mention tech that I've worked with for long enough to not feel intimidated by.

brittle copper Jun 22, 2018, 7:52 PM

#

Instead of shitty one liners

#

Hmm, only python and django then

deep cave Jun 22, 2018, 7:53 PM

#

like, I have C++ experience too but it scares the shit outta me so it's not on my list :P

strange thorn Jun 22, 2018, 7:53 PM

#

i dont feel intimidated by LLVM

#

i just hate it

native tide Jun 22, 2018, 7:54 PM

#

@deep cave, thanks, I learned something new about what to put in my CV :=)

brittle copper Jun 22, 2018, 7:54 PM

#

Welp thank you lemon, I'm gonna apply to some stuff and as soon as I get a job I'm gonna treat you a döner :3

deep cave Jun 22, 2018, 7:55 PM

#

sounds good

native tide Jun 22, 2018, 7:55 PM

#

actually, techs I'm not intimidated by has become my main section :D

#

@boreal tree, can you try:

print(client.service.sendBill('20100066603', encoded))

#

I've no idea why the error would be about ZIP when you're not sending a zip file

boreal tree Jun 22, 2018, 8:03 PM

#

the thing is the ws expects the name of the zip and then the zip encoded on base64.
*If i give it the .xml encoded i get the same error as when i send the .zip
*If I send an incorrect .zip name it returns an error saying the name of the zip is incorrect
*If i send the zip encoded with its name written wrong. it returns an error saying the name of the zip is incorrect

#

The ws, IS recieving my request, but it's failing who knows why. so up until now i have 2 theories

#

The ws is poorly programmed and it just doesn't work properly most of the time.
The ws has some kind of security that doesn't allow requests from unknown senders. So SoapUI is trusty but doing your own code on an IDE just isn't

native tide Jun 22, 2018, 8:04 PM

#

ok, so at least there's another error when you send the wrong name

boreal tree Jun 22, 2018, 8:05 PM

#

yeah, that's why i know the ws is at least recieving my data

native tide Jun 22, 2018, 8:05 PM

#

yeah

boreal tree Jun 22, 2018, 8:06 PM

#

so... i'm pretty much f*cked right? xd

native tide Jun 22, 2018, 8:06 PM

#

yesno

#

:D

#

can you try your code again (the original 'good') code

boreal tree Jun 22, 2018, 8:07 PM

#

The sad part about this is that. I've read on forums that the ws provider doesn't actually respond for this errors. If i try to contact them, they will probably ask me to reboot my modem. That's what people said the ws provider told them.

native tide Jun 22, 2018, 8:07 PM

#

and see if the ticker number goes up everytime you get the error?

#

:s

#

ticket-

boreal tree Jun 22, 2018, 8:08 PM

#

oh right the ticket

#

let's ssee

native tide Jun 22, 2018, 8:08 PM

#

tickets could be how they track errors

boreal tree Jun 22, 2018, 8:09 PM

#

yeah the ticket number vary

#

1529697587691
1529698118169
1529698145386
is what i got from 3 consecutive requests

native tide Jun 22, 2018, 8:11 PM

#

yeah, that's probaly how they track them

#

am

#

is there documentation for the service

#

?

boreal tree Jun 22, 2018, 8:11 PM

#

well i'm planning on doing a documentation on how i got till this point.

native tide Jun 22, 2018, 8:11 PM

#

it's possible you could find the anwser there

boreal tree Jun 22, 2018, 8:12 PM

#

yeah, there is documentation for the ws

native tide Jun 22, 2018, 8:12 PM

#

it's in spanish?

boreal tree Jun 22, 2018, 8:12 PM

#

i'm looking for it rn

#

yeah, it's on spanish

native tide Jun 22, 2018, 8:12 PM

#

sorry, can't help you with that :)

#

first, I'd look specifically for the spendBill method and see what you can find out from that

#

then I'd go look for filetypes and if there are any errors associated with them

boreal tree Jun 22, 2018, 8:14 PM

#

feel free to take a look at the diagram on page 16.
It's public after all.

no hablo espanol, unfortunately :)

boreal tree Jun 22, 2018, 8:14 PM

#

yeah, but i was talking about this

📎 unknown.png

#

that's what the ws does, basically

native tide Jun 22, 2018, 8:15 PM

#

maybe there are some details in the documentation that might give you a clue what could be wrong

boreal tree Jun 22, 2018, 8:17 PM

#

I hope.
I'm reading it again

native tide Jun 22, 2018, 8:18 PM

#

also are you 100% that the error from SOAP Ui is the 'correct' one?

boreal tree Jun 22, 2018, 8:18 PM

#

yeah. I'm sure about that one.

#

Since it's analyzing the xml and telling me the field I put wrong data, has wrong data.

#

:P

#

before that I had other kind of error from other wrong data I put there. As I said before all data on that xml is fictional. For now I just gotta make sure i send my data through my custom code on python.

native tide Jun 22, 2018, 8:26 PM

#

and the error from your program complains about the whole file?

boreal tree Jun 22, 2018, 8:28 PM

#

it says

 Validation File count error'

#

wait i think i found my problem

native tide Jun 22, 2018, 8:32 PM

#

?

#

do tell

boreal tree Jun 22, 2018, 8:35 PM

#

nvm tried to send another xml inside the zip to see if it still gave me the same error (hoping for it to not) But it did give me the same error. So i got nothing.

#

¯_(ツ)_/¯

native tide Jun 22, 2018, 8:38 PM

#

:D

#

can you run the program with python 2?

boreal tree Jun 22, 2018, 8:45 PM

#

i guess, but i got to install python 2 😛

#

i'll try it tho

native tide Jun 22, 2018, 8:45 PM

#

which OS are you using?

boreal tree Jun 22, 2018, 8:45 PM

#

win10

#

64 bits

native tide Jun 22, 2018, 8:45 PM

#

_<

#

don't know if I'd bother. I don't think it will change anything

boreal tree Jun 22, 2018, 8:49 PM

#

i'll still try it tho. ty @native tide ~

#

If i get to make this to work. I'll do a documentation, but if I don't... i'll still probably do it. lolz

native tide Jun 22, 2018, 8:55 PM

#

you know what I'd try before that?

#

use create_message to see the created xml

boreal tree Jun 22, 2018, 9:17 PM

#

like this?

from zeep import Client, Settings
from zeep.wsse.username import UsernameToken

import base64

with open("20100066603-01-F001-1.zip", "rb") as f:

    encoded = base64.b64encode(bytes)
settings = Settings(strict=False, xml_huge_tree=True)
wsdl = 'https://e-beta.sunat.gob.pe/ol-ti-itcpfegem-beta/billService?wsdl'
client = Client(wsdl=wsdl, wsse=UsernameToken('20100066603MODDATOS', 'moddatos'), settings=settings)

print(node)

native tide Jun 22, 2018, 9:18 PM

#

not sure. I have to check the docs

#

does it work?

boreal tree Jun 22, 2018, 9:18 PM

#

nope, same error

native tide Jun 22, 2018, 9:18 PM

#

?

boreal tree Jun 22, 2018, 9:19 PM

#

zeep.exceptions.Fault: El archivo ZIP no contiene comprobantes - Detalle: xxx.xxx.xxx value='ticket: 1529702201943 error: Validation File count error'

#

i have found a github project from other person for consuming this ws, but it's on c#. I'll check and try it out. Maybe there's something i missed.

native tide Jun 22, 2018, 9:23 PM

#

like this maybe:

node = client.create_message(client.service, 'sendBill' , fileName='20100066603-01-F001-1.zip',  contentFile=encoded)

#

client.service.sendBill() actually sends whatever you have

#

so that's no good if you wan't to inspect the created xml before it is sent to the server

boreal tree Jun 22, 2018, 9:27 PM

#

your code returns this.

don't worry, i got to go too rn 😛

loud walrus Jun 22, 2018, 10:38 PM

#

hey

#

which is better flask or django

#

and is there any good ides for web development that are compatible with either of these frameworks

meager anchor Jun 22, 2018, 10:43 PM

#

which is better flask or django ah yes, the "vim vs emacs" of python

#

flask is usually recommended for smaller projects

#

its a lot more customizable

#

and gives you a lot more freedom for doing stuff

loud walrus Jun 22, 2018, 10:43 PM

#

lol

meager anchor Jun 22, 2018, 10:44 PM

#

django is batteries-included, brings e.g. migrations, tests, and whatnot out of the box

loud walrus Jun 22, 2018, 10:44 PM

#

and I absolutely hate html

meager anchor Jun 22, 2018, 10:44 PM

#

so "which is better"? neither, they're both amazing frameworks

loud walrus Jun 22, 2018, 10:44 PM

#

is there any way to like

#

any recommendations getting into html and css?

#

I never understood how it really works, even when I try to learn, creating sites with even a login page seem confusing.

meager anchor Jun 22, 2018, 10:45 PM

#

i found w3schools pretty good

#

https://www.w3schools.com/html/default.asp

loud walrus Jun 22, 2018, 10:45 PM

#

its not that I dont know how

#

Is there a way I can use a wysiwyg ide?

#

like bootstrap studio or something?

#

or would that be pointless?

meager anchor Jun 22, 2018, 10:46 PM

#

html really isn't that hard

loud walrus Jun 22, 2018, 10:46 PM

#

like so I can make a half decent control panel

#

I always found actual GUI work easier

#

cause coordinates make sense

#

but like bootstrap and all that make absolutely zero sense.

#

in other words, what would it take to make a login page using firebase

#

I need to have the user sign in with email and password

#

and then check firebase's api, and after that store their user ID in a cookie?

meager anchor Jun 22, 2018, 10:48 PM

#

all the firebase jazz isn't of interest for the frontend, you do that on the backend, unless i don't understand what firebase is

#

the frontend just displays it

loud walrus Jun 22, 2018, 10:49 PM

#

correct

#

but the backend is django?

#

aka python

#

aka actually logging in?

#

I just dont get the relationship between django and the actual html and css?

#

django handles the interactions, but that confuses me... lol

#

how does it know when the button is pressed or whatever?

#

I am more of a OpenGL man, so I dont really relate to any of this.

#

{% if messg %}
<script>
    alert('{{ messg }}');
</script>

#

oh I use javascript to check for relationships in the data?

#

srry I am kind of an idiot

#

like @meager anchor would it be possible to use Adobe DreamWeaver for the frontend actual html, and then use django for the backend?

meager anchor Jun 22, 2018, 10:56 PM

#

no idea how dreamweaver works, i write my html myself

#

keep in mind that you'd work with django templates though

deep cave Jun 22, 2018, 11:12 PM

#

there is no support for the django template language, or jinja2 or mako in Dreamweaver.

#

so it's a terrible choice.

#

it would be theoretically possible, but not practical

brave mantle Jun 22, 2018, 11:12 PM

#

Forget dreamweaver

#

Forget pretty much anything that writes html for you to be honest

#

You should just learn html

yep

#

i saw some of sentdex django tutorial and there while explaining about {% block content %} {% endblock %} , he said its ginger logic, but i dont really get what is this logic

#

can somebody explain me what exactly is ginger logic?

grand badge Jun 23, 2018, 11:41 AM

#

not ginger, jinja

#

also, django by default doesnt use jinja2 syntax

teal mural Jun 23, 2018, 11:41 AM

#

^

grand badge Jun 23, 2018, 11:41 AM

#

its just similiar to jinja

#

@jade rapids when we talk about logic in templates, we are talking about added functionality in templates that you cant achieve with just html

#

anything that starts with {% and ends with %} is logic

jade rapids Jun 23, 2018, 11:44 AM

#

oh thank you

#

now its more clear and i feel more dumb lol

grand badge Jun 23, 2018, 11:45 AM

#

for example

{% if not condition %}
    <h1>Some text</h1>
{% endif %}

#

you will only see the <h1> if the condition variable is false

#

you can translate this into python

if not condition:
    print('some text')

jade rapids Jun 23, 2018, 11:47 AM

#

ohh okie

#

so we can write any logic between {% %} ?

grand badge Jun 23, 2018, 11:48 AM

#

yes

#

remember, logic must always be closed, like variables

#

{% block content %}
{% endblock %}

jade rapids Jun 23, 2018, 11:49 AM

#

are there variables also in jinja?

grand badge Jun 23, 2018, 11:49 AM

#

there is

#

but in django, the default isnt jinja

#

they work the same way

#

{{ variable }}

#

but some syntax is different

jade rapids Jun 23, 2018, 11:50 AM

#

do i need to learn jinja first for understanding django?

grand badge Jun 23, 2018, 11:50 AM

#

so i'm debating about going for flask or django as a starting point for web development

#

django looks more interesting though

brittle copper Jun 23, 2018, 4:55 PM

#

Both are great frameworks

desert ingot Jun 23, 2018, 4:55 PM

#

^

#

it depends on what you're trying to build

#

for most webapps i'd say django

#

flask for other projects where you'd want to have more controol

modern acorn Jun 23, 2018, 4:57 PM

#

I honestly dont know

#

I just want to create feature rich websites, and perhaps make a small social media website or something just for practise

#

I'm just interested to get into back-end development

brittle copper Jun 23, 2018, 4:59 PM

#

Doesn't really matter, the difference is django has lots of stuff built-in

#

And Flask doesn't

#

If you are okay with using the built-in go with django

#

If you want to use your own stuff, go with flask and choose it

modern acorn Jun 23, 2018, 5:00 PM

#

I'm just more concerned if using django will hold me back when it comes to gaining knowledge

brittle copper Jun 23, 2018, 5:00 PM

#

Knowledge about what?

modern acorn Jun 23, 2018, 5:00 PM

#

web development and python in general

brittle copper Jun 23, 2018, 5:01 PM

#

You should already know python in general to dive into a framework

modern acorn Jun 23, 2018, 5:02 PM

#

I do lol

#

I've just learned the basics of the language, and I'm trying to dive into a framework

brittle copper Jun 23, 2018, 5:03 PM

#

How basics

modern acorn Jun 23, 2018, 5:04 PM

#

Things you would learn from going through a book

#

I've only done low-level stuff in the past in C, but this is the first time im diving into more abstract languages and trying to develop software

brittle copper Jun 23, 2018, 5:09 PM

#

If you already know deque, collections, socket, itertools, and etc

#

And if you can use them

#

Those are just literally random libraries I pulled out of my ass by the way

#

If you know what classes are etc and etc

#

You are good to go

#

You can just pick django if you want batteries included and flask if not

#

There is nothing in there that will teach you python anyway, it is just a whole new world called web dev

#

using django will hold me back when it comes to gaining knowledge

#

I mean django offers a ORM for database for instance built-in

#

But you can just choose not to use it

#

Django offers a built-in user model that you don't have to use

#

Django offers an administration page you can opt-out

#

If you want to learn how to use databases especially for instance you can go with flask to learn how to integrate your project with a database

Does anyone know why, in Django/DRF posting data from rest_framework.test.RequestsClient object results in data getting received as QueryDict without keeping data's nature, i.e.

# in my test
data = {'foo': [1, 2, 3]}
client.post(url, data)

# in my view
print(request.data)
# prints {'foo': ['1', '2', '3']}, as you can see 1, 2, 3 got converted to strings, why?

And finally, how can I enforce data's nature to be kept as original?

unborn terrace Jun 26, 2018, 10:16 AM

#

Found solution, using the json named argument instead of data, like this:

client.post(url, json=data)

What a good way to get started with django/flask and which should i choose

native tide Jun 27, 2018, 10:10 AM

#

depends on what you need

olive wharf Jun 27, 2018, 10:11 AM

#

Something to tinker with to get familiar with the concepts

#

Theres no need other than self improvement

native tide Jun 27, 2018, 10:12 AM

Both are great. I don't think there's the right answer here.

official tutorials should get you on your way

olive wharf Jun 27, 2018, 10:12 AM

What are the key differences between the libs then?

native tide Jun 27, 2018, 10:12 AM

django does more for you out of the box

Flask is more flexible

Welp, might as well just try both then

native tide Jun 27, 2018, 10:17 AM

#

also don't pay too much attention to flask being a "micro" framework

#

it doesn't mean it's not suitable for large projects

#

but it does take a bit more work

#

and the default environment supports only one request at once afaik

#

on flask

#

aren't Django and Flask both synchronous?

She

native tide Jun 29, 2018, 7:21 AM

she?

#

like I mean my own, about web-dev I have no I dea how grid templates work

#

hey boys, I'm still using flask and when you render a template and send a variable along with it
return render_template("MyPage.html", MyList = [Bunch of string])

whenever this get's parsed in the js code
var MyArray = {{ title }}

jinja2 automatically escapes the apostrophes
so for example the list [ 'memes', 'dreams'] in python transfered to JS becomes [&#39memes&#39, &#39dreams&#39]

I already tried to add safe in the html file
so when I take the python array it doesn't automatically turn them into those hex codes

var Myarray = {{ title | safe }}

yet I still get these escape codes in my JS array, when I take at look through dev tools
if anyone knows how to solve this please DM me.
I have also tried

import jinja2
MyList = [ Bunch of strings]
render_template("MyPage.html",Mylist = jinja2.escape(MyList)

still doesn't work

deep prism Jun 29, 2018, 7:42 AM

@native tide
Nothing special needs to be done. Are you sure that your MyList is truly just a list of strings?

📎 unknown.png

#

📎 unknown.png

native tide Jun 29, 2018, 7:43 AM

#

well I think it's a list of strings

#

[('text', 6.400466379878729), ('rdata',5.6693643070101585), ('data', 2.0677782640502413), ('pdata', 5.873699144062637), ('didat', 0.8050372616935684), ('CPADinfo', 0.12227588125913882), ('rsrc', 6.932746768002647), ('reloc', 5.36807357956736)]

#

and then on the html page in the javascript part the variable has the ' in it which gets escaped to &#39

#

@deep prism

deep prism Jun 29, 2018, 7:47 AM

#

ah okay, it's mostly about the javascript bit then.

                file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
            MyDict = {}
            MyDict = PyDetect.MethMain(os.path.join(app.config['UPLOAD_FOLDER'],filename),MyDict)
            session['FilePath'] = os.path.join(app.config['UPLOAD_FOLDER'],filename)
            return redirect('http://localhost:5000/Results')

#

by the way yes discord formatting sux

#

app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER

#

UPLOAD_FOLDER = 'uploads'

deep prism Jun 29, 2018, 11:57 AM

#

when you say it sometimes works and sometimes it doesn.t is that with different files or the same one always?

native tide Jun 29, 2018, 11:58 AM

#

depends

#

it's usually when I pick the same file in a session more than once

#

@deep prism just tested

#

it's when you pick after a session

#

when you pick the same file more that one time a session

#

a session being a restart of the flask server

deep prism Jun 29, 2018, 12:07 PM

#

where does it fail btw, it's in the file.save right?

native tide Jun 29, 2018, 12:08 PM

#

yeah

supple barn Jun 29, 2018, 12:10 PM

#

if not os.path.isdir(os.path.join(app.config['UPLOAD_FOLDER'], filename)) != False:

#

what is this supposed to do?

#

filename will never be a dir

#

do you maybe want to check os.path.exists or os.path.isfile instead?

#

and why the double... or triple negation?

native tide Jun 29, 2018, 12:11 PM

#

yes

supple barn Jun 29, 2018, 12:11 PM

#

I would simplify that if for now

native tide Jun 29, 2018, 12:11 PM

#

os.path.exists

supple barn Jun 29, 2018, 12:11 PM

#

so

native tide Jun 29, 2018, 12:11 PM

#

that's what I'm gonna use

supple barn Jun 29, 2018, 12:11 PM

#

if not os.path.exists(os.path.join(app.config['UPLOAD_FOLDER'], filename)):

#

there's no need for the != False

native tide Jun 29, 2018, 12:12 PM

#

yeah I know it's like C syntax, but I doubt my self other wise

supple barn Jun 29, 2018, 12:12 PM

#

Putting it is just confusing

#

don't

#

because you put it there initially it probably also failed

#

because you mixed up your negations

native tide Jun 29, 2018, 12:13 PM

#

nah I put a print there and it worked

deep prism Jun 29, 2018, 12:13 PM

#

yea, not not-equals is very confusing.
either way, your code works just fine for me.

native tide Jun 29, 2018, 12:13 PM

#

everytime?

supple barn Jun 29, 2018, 12:13 PM

#

It worked in strange cases then, because you were checking for isdir from the beginning

deep prism Jun 29, 2018, 12:14 PM

#

yea, every time

#

I didnt do that secure file though...

#

probably should

native tide Jun 29, 2018, 12:15 PM

#

works perfectly now

#

it was that isdir

#

so it's os.path.exists thanks

supple barn Jun 29, 2018, 12:15 PM

#

fix your negations

#

I know you think it's ok, but writing C code in Python is not really

#

for anyone else reading your code

native tide Jun 29, 2018, 12:16 PM

#

it was that one thing, and I know it wasn't good

#

I just wasnt sure

#

most of my code is python like

#

no worries 😃

supple barn Jun 29, 2018, 12:17 PM

#

great 😃

deep prism Jun 29, 2018, 12:17 PM

#

it makes no sense though. that isdir thing is just an if-statement. it doesn't change variables, it shouldn't have any effect on the error you had.

native tide Jun 29, 2018, 12:17 PM

#

I know

#

it makes no fucking sense

supple barn Jun 29, 2018, 12:17 PM

#

well

#

you checked if a file that existed was a directory

#

that will always be false

brittle copper Jun 29, 2018, 12:18 PM

#

It is an os error tho

supple barn Jun 29, 2018, 12:18 PM

#

so file.save tried to overwrite an existing file

#

maybe that raised the error?

native tide Jun 29, 2018, 12:18 PM

#

this is the line on which it errored
file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))

supple barn Jun 29, 2018, 12:18 PM

#

what was the exact error again?

#

ah I see

native tide Jun 29, 2018, 12:19 PM

#

📎 upload.PNG

supple barn Jun 29, 2018, 12:19 PM

#

well

#

I think it uses shutil internally

#

the file.save

#

and it tried to move/copy a file where one already was

#

and raised an OSError

#

it does that for some functions

deep prism Jun 29, 2018, 12:20 PM

#

where does a double backslash come from though.

native tide Jun 29, 2018, 12:20 PM

#

I don't know

supple barn Jun 29, 2018, 12:20 PM

#

the double slashback is there because he is using it on Windows

native tide Jun 29, 2018, 12:20 PM

#

yeah

supple barn Jun 29, 2018, 12:20 PM

#

and they used repr()

deep prism Jun 29, 2018, 12:20 PM

#

I know os.path.join will make a double backslash if the filename has a backslash, but why would filename have that

supple barn Jun 29, 2018, 12:20 PM

#

to display the error

#

pretty sure at least

#

user@host ~ $ print('a\\test')
a\test
user@host ~ $ print(repr('a\\test'))
'a\\test'

#

so the exception text was repr(path) that failed

native tide Jun 29, 2018, 12:21 PM

#

I already tried 50 file uploads

#

but lemme check again

supple barn Jun 29, 2018, 12:22 PM

#

it failed before because shutil (most likely) tried to move/copy/save a file onto an existing file

#

probably from a /tmp dir

#

because you checked isdir on an existing path

#

always causing the save.file to be triggered

deep prism Jun 29, 2018, 12:22 PM

#

the file.save is fine for overwriting files though

#

unless of course it's in use or something prevents it.

supple barn Jun 29, 2018, 12:22 PM

#

Are you sure about that? This seems to imply differently

#

do you have the full traceback @native tide ?

#

it would even make sense to not just allow overwrites if it's part of flask or whatever

#

because that could be easily exploited

native tide Jun 29, 2018, 12:23 PM

#

yes I do

supple barn Jun 29, 2018, 12:23 PM

#

can you post it?

native tide Jun 29, 2018, 12:23 PM

#

not anymore since the problem is resolved

#

it's not in the console since I restarted the server

supple barn Jun 29, 2018, 12:25 PM

#

hm seems correct, that it should have been overwritten. No idea then

#

oh well

deep prism Jun 29, 2018, 12:26 PM

#

I changed permission on my file to overwrite and it gives me PermissionError: [Errno 13] Permission denied: '/tmp/uploads/test.html'
So the OS would probably give a more clearer error than just "invalid argument" if it were in use, or invalid permissions.

#

Idk why it's just "invalid argument", it has to be because of that backslash stuff

supple barn Jun 29, 2018, 12:27 PM

#

C:\test\test.txt
user@host ~ $ print(repr(my_path))
'C:\\test\\test.txt'
user@host ~ $

#

again, the double backslashes are part of the repr representation of a string

#

which is used in the raised exception

#

the actual string does not have 2 backslashes

#

they are just escaped so you know that the escape sequence \t isn't meant

deep prism Jun 29, 2018, 12:28 PM

#

What other "arguments" can there be though

supple barn Jun 29, 2018, 12:28 PM

#

ok wait.

#

http://i.imgur.com/sg8hKAM.png

Imgur

flameshot_screenshot

#

this is what happens

#

only if you actually have a tab-escape sequence \t

#

will repr show \ without an escaping \\

#

the argument was that he attempted to save a file where one already was, and something failed.

native tide Jun 29, 2018, 12:42 PM

#

that actually makes sense

buoyant ledge Jun 29, 2018, 5:24 PM

There’s an onclick event you can add inside image tags or add an event listener directly to the ID

sour heath Jun 29, 2018, 5:29 PM

#

within flask?

#

@buoyant ledge

buoyant ledge Jun 29, 2018, 5:37 PM

You’d do it on the html side

sour heath Jun 29, 2018, 5:37 PM

like in my template?

buoyant ledge Jun 29, 2018, 5:39 PM

#

Yeah. That should work. I don’t know the exact implementation in flask but that’s how it’s done in traditional setups

#

And the html should work the same

#

Are you sure that the image exists?
Where are you putting this <img> tag

sour heath Jun 29, 2018, 9:50 PM

I'm sure it exists as the path is copied from the image itself

You will not want to use flask for this

Right off the bat

You're implementing the webserver in the same program as your bot

i've already tried web.py, didn't work well either

brave mantle Jul 1, 2018, 10:59 AM

Yeah no, that won't work, because you need something that supports asyncio

You should be using aiohttp

solemn pawn Jul 1, 2018, 10:59 AM

can i receive webhooks with aiohttp?

brave mantle Jul 1, 2018, 10:59 AM

okay, gonna look into that, thank you

brave mantle Jul 1, 2018, 11:00 AM

You should consider whether this is really what you want though

Most of the time, the site and bot parts are separate apps

i don't want to host a site

brave mantle Jul 1, 2018, 11:00 AM

solemn pawn Jul 1, 2018, 11:01 AM

the only thing this code should do is listen for incoming webhooks from Discord Bot List

hmm i have not done any frontend development before, but i do know javacript ,php, and html (css is my weakest skill) and i have almost no skills in mkaing things look nice and i need to make a responsive website, i'd sort of wanna do it with python.
i have made a api for the site with python and flask.
how should i proceed for the front end? django?

#

aand i have deadline in 4 weeks 😐

deep cave Jul 1, 2018, 10:42 PM

#

no reason you can't continue using flask

#

if you've already got experience with it, it's probably not a bad choice

#

html and css will still be required to make it look nice no matter which framework you choose.

#

but you could use something like bootstrap or bulma to do the heavy lifting css for you

#

bulma is really nice.

#

with bulma, flask and some html you'd have a website looking pretty good in mere days.

#

as for responsive, that'll probably require either css or javascript to pull off - it's not gonna be possible to do with just python

#

but you said you knew js so that sounds like it won't be a problem.

dense slate Jul 1, 2018, 10:47 PM

#

@wary mantle You can do this pretty easily with some javascript. Stackoverflow has a lot of good examples. Might not all be for bootstrap, but you can probably hack your way through their answers to just add a simple BS button.

Is there anything like a listbox from tkinter in html?

deep cave Jul 4, 2018, 6:37 PM

no. but you could build a table and make each row clickable and you'd get close.

then add some buttons

#

might need a js event handler to make the table rows clickable though. but it's not hard to google a solution for.

#

(tags like <tr> don't like being wrapped in <a>s.)

deep cave Jul 4, 2018, 6:59 PM

are you using a python web framework?

#

in that case you can still build that

#

you just spit out that list when you render your template and then have a for loop in the table that makes a table row for each list item

No. We do not provide one-on-one tutoring - you can hire someone locally if you really need that. We also prefer that questions are answered in a public channel as it means that everyone else present is able to learn from them. If you're working with code that you are unable to disclose for any reason, you should try to make your question more general and write a separate, small piece of code to illustrate your problem.

@native tide what does the .wsgi consist of?

gentle sapphire Jul 6, 2018, 12:30 PM

#

it's a run file,

#

it runs the web app

#

so, mostly an import to call the app, and a main()

keen ore Jul 6, 2018, 4:04 PM

#

can i make a form with "add field" functionality with flask_wtf? i want to have a form where users can add ass many skills as they want in a single go,sort of like this:

Skill name:[           ]
Skill level:  [           ]
add skill...
[Submit]

#

and clicking add skill makes it like this

Skill name:[           ]

#

so can someone explain how onclick works?

native tide Jul 6, 2018, 4:22 PM

#

Does it have any connection with python?

sour heath Jul 6, 2018, 4:22 PM

#

I want to be able to call a function upon clicking an image, correct me if I'm wrong but I think thats the main solution I should use

#

by that what do you mean?

native tide Jul 6, 2018, 4:22 PM

#

This is a python server.

sour heath Jul 6, 2018, 4:22 PM

#

the function being a python function

#

yes

native tide Jul 6, 2018, 4:23 PM

#

Oh

#

ok

#

What do you mean by "how onclick works"?

sour heath Jul 6, 2018, 4:24 PM

#

within html

native tide Jul 6, 2018, 4:24 PM

#

Like this:

<button onclick="js action here">button</button>```

#

Example with button.

#

Same with img but you set the source.

sour heath Jul 6, 2018, 4:25 PM

#

so why is it a js action?

native tide Jul 6, 2018, 4:25 PM

#

Because that how HTML works.

#

kind steppe Jul 6, 2018, 4:29 PM

#

You can't run Python in HTML @sour heath

#

@native tide This channel can be used for talking about HTML, CSS or JavaScript

sour heath Jul 6, 2018, 4:29 PM

#

okay, thanks

native tide Jul 6, 2018, 4:30 PM

#

Oh, ok. I wasn't sure.

kind steppe Jul 6, 2018, 4:30 PM

#

JavaScript is used for scripting webpages, so a HTML element event will always trigger a JavaScript function

#

No problem

sour heath Jul 6, 2018, 4:30 PM

#

and you can write the js within the html?

kind steppe Jul 6, 2018, 4:31 PM

#

you can

#

So

#

example time ✨

#

<script>
function myFunction() {
    alert("You clicked the button!")
}
</script>

<button onclick="myFunction()">Click me!</button>

sour heath Jul 6, 2018, 4:32 PM

#

so within the js, you can call python functions, which is the whole tie between them?

kind steppe Jul 6, 2018, 4:32 PM

#

No

#

There is no tie between them

sour heath Jul 6, 2018, 4:32 PM

#

oh

kind steppe Jul 6, 2018, 4:32 PM

#

Python is nothing to do with frontend web development

sour heath Jul 6, 2018, 4:32 PM

#

oh

kind steppe Jul 6, 2018, 4:32 PM

#

There are various ways you can write "Python" in the browser, but I don't recommend any of them

sour heath Jul 6, 2018, 4:33 PM

#

so trying to write a web program with python involved seems useless?

kind steppe Jul 6, 2018, 4:33 PM

#

Yes

#

because you can't do it

#

you will either write python which gets converted into JS, or just end up using JS

sour heath Jul 6, 2018, 4:33 PM

#

well, good to know

kind steppe Jul 6, 2018, 4:34 PM

#

If you are looking to learn web dev, it is one of the things codecademy offers a relatively good course on, so I recommend that

sour heath Jul 6, 2018, 4:34 PM

#

well, I'm using python

#

so I'm not sure

kind steppe Jul 6, 2018, 4:34 PM

#

Python is a good skill for backend web dev

#

You may not be able to write the bit the user sees in Python, but you can certainly write the bit which sends the data to the user and processes requests in Python

#

sour heath Jul 6, 2018, 4:36 PM

#

well, I don't think I could do it, I'll just have to convert to some gui

kind steppe Jul 6, 2018, 4:36 PM

#

If you are looking into GUI's, I recommend looking at PySide2

sour heath Jul 6, 2018, 4:37 PM

#

okay, thanks

#

if you have any questions, #user-interfaces is the place for them

sour heath Jul 6, 2018, 4:38 PM

#

wait, were you suggesting I use flask?

#

because thats like, exactly what I've been using

kind steppe Jul 6, 2018, 4:41 PM

#

I was saying python can be used on backend not front end

#

if you are already doing that then that is awesome :D

sour heath Jul 6, 2018, 4:41 PM

#

well, I'm not sure

#

would buttons working be similar?

kind steppe Jul 6, 2018, 4:42 PM

#

I'm really confused as to what you are asking about now

#

Flask is not a GUI framework

sour heath Jul 6, 2018, 4:42 PM

#

yes, I know that

kind steppe Jul 6, 2018, 4:42 PM

#

buttons would be similar yes

sour heath Jul 6, 2018, 4:42 PM

#

great, so using get and post?

kind steppe Jul 6, 2018, 4:43 PM

#

You could tie it in using something like requests, yes

sour heath Jul 6, 2018, 4:43 PM

#

using onclick?

kind steppe Jul 6, 2018, 4:43 PM

#

Not exactly onclick, because it is not HTML

sour heath Jul 6, 2018, 4:43 PM

#

oh

kind steppe Jul 6, 2018, 4:43 PM

#

take a look at this

#

we create a button

sour heath Jul 6, 2018, 4:44 PM

#

is this the gui again?

kind steppe Jul 6, 2018, 4:44 PM

#

and then we connect the button to a say_hello function

#

Yes, this is pyside2

#

In fact

#

let's move to #user-interfaces

keen ore Jul 7, 2018, 12:24 AM

#

reload with shift f5
