Looking for a cool co-founder / remote possible

[ExpoTor com]

ExpoTor.com is a young remote-first start-up in Germany looking for an
ambition experienced full-stack Python(React) Developer to join our journey


With our SaaS solution, we help SMEs at trade shows get more ROI and
freelancers get more exposure and sell more in the MICE space. Time- and
money-wasting exhibiting must be passé – we will give them back the
hundreds of hours they spend for it during a year.

Our mission is to „make the small ones big again“ by matching the right
demand-offer we can help a lot of small businesses and even individuals
with the first mobile and web-based expo platform that allows effective
decision making by digitally transforming the global exhibiting process. We
reduce waste by cutting financial, administrative and repetitive work. We
save CO2 and reduce waste around the MICE industry!



As a co-founder and automation engineer/developer, you will be improving
the technical logic and generate growth through your innovative
technological input. Your work will contribute to the excellence of our
software based on Django, MySQL, jQuery, BS, etc. Our goal is to create a
product, which can compete with any other MICE application.

 You should bring…

   - 5+ years of hands-on experience developing, releasing, automated
   unit/regression testing and maintaining large-scale software applications
   (web/mobile) with Python/Django
   - 2+ years of professional experience with enterprise architecture and
   developing highly scalable websites/services
   - experience in introducing blockchain for SaaS products/platforms
   - some experience with React JS and React Native would be great – as
   future CTO and tech decision-maker, it is important to bring full-stack
   experience
   - a university degree is not important
   - freelancing / own startup experience would be great
   - respecting deadlines and bringing the initiative



If you already have software in SaaS / AI CRM / blockchain / Smart
Contracts and looking to find a match to market it – we are happy to talk
about a merge/co-founding. We appreciate creativity and open-minded people.
We encourage only people who really want to make-it-happen and bring a
value-added contribution to contact us. Those looking for a sleeping 9-5
job would not be at the right place here.

Re: My developers have run amok

[Derek]

I am not sure I understand about the "size and synchronization" but I 
assume that is to do with them not giving you adequate infrastructure.

I don't think the DB advice is in any way specific to Django - I'd make the 
same recommendation regardless of the framework being adopted - but 
obviously there are sometimes constraints that force our hand to do things 
in non-optimal ways.  You have my sympathies (for what they are worth).

Re: migrating from 2.7 to 3.x on Ubuntu

[Ryan Nowakowski]

Seems doable. I would leave nginx out of it and just run gunicorn Python 3 with 
Apache. Also I would do the release upgrade before.

linking django app to slurm db

[Bissane Belhadji]

Hi everyone!
I've been working on this project with SLURM for quite a while now and I've 
been experiencing a massive writer's block, I'm working on a portal that 
will allow employees register to slurm's database and run their jobs on 
accounts along with several other things.  I have built this django 
application with an LDAP and Kerberos backend to authenticate against the 
corporate internal authentication system and I'm sorte of familiar with how 
slurm works now, however, I can't for the life of me figure out how to link 
my django app to the slurm db 
I have a few ideas in mind that I'm currently testing out, but any new 
approach to this or even the slightest suggestion is greatly appreciated

Re: Problems with first program

[Ranganath Kulkarni]

Always use editors like pycharm which will take care of indentation if not 
it will complain syntax errors if there are any in your program.

Django credit card redaction app - - MultiValueDictKeyError

[drone4four]

Hello!

I’m trying to run a basic Django app which redacts a 16 digit number 
entered by the user. I had a it running a few minutes ago. I’m not sure 
what I changed, but now I am getting a MultiValueDictKeyError. I’ve triple 
checked every variable. The only dictionary in my project is in views.py at 
line 7. As far as I can tell, it’s all accurate and positioned correctly. I 
don’t recall changing this dictionary or any other operator around this 
line. I’m stumped. What would you people suggest? Have a look at my setup.


*Here is the error and traceback in full:* https://pastebin.com/QwSrmAJx 

Here is my urls.py:
from django.conf.urls import  include, url



from django.contrib import admin

from django.urls import path

from . import views


urlpatterns = [

   url(r'^admin/', admin.site.urls),

   url(r'^$', views.home, name='home'),



views.py:
from django.http import HttpResponse



from django.shortcuts import render


def home(request):

   number = request.GET['ccEntry']

   redacted_num = '   {}'.format(number[-4:])

   return render(request, 'home.html', {'number':number, 'redacted_num':
redacted_num})



home.html template:









 

   Enter your fake Chuckee Cheese Neptune credit card number!

   

 

 

 

   Must be a 16 digit number.

 

 

   

   

   

   

   Original Card Number:

   

   {{ number }}

   

   Redacted Card Number:

   

   {{ redacted_num }}

   

Did this work?

Re: Django credit card redaction app - - MultiValueDictKeyError

[Sam Taiwo]

I would be careful how you pass the data on get, somewhere in your front
end code you are probably not passing the data through as you expected.
Instead of using .GET, use .GET.get to get your data. This will either
return the value you want, or none. I think you have made the error of not
passing your data to the get header as you didn't explicitly write this on
the form element. Check the URL and log the get object in Django to make
sure the data is actually appearing in both.

Re: Django credit card redaction app - - MultiValueDictKeyError

Thanks, Sam for the help.

I looked up GET.get Django and found an SO post titled, “Django request.GET 
” which has 
quite a few up votes. Based on that SO answer, In my views.py I changed the 
line (where I declare the number variable) from `number = 
request.GET['ccEntry']` to `number = request.GET.get['ccEntry', None]`  

That gives a different error (a type error this time): 
https://pastebin.com/L81LVtzi 

You also mentioned my front end. I had included the template in my original 
post. I have since refined it so it is more readable. Here is my improved 
home.html template:







  Search 



  





 

   Enter your fake Chuckee Cheese Neptune credit card number!

   

  Must be a 16 digit number. 

   

 



   Original Card Number:

   {{ number }}

   Redacted Card Number:

   {{ redacted_num }}

Did this work?

I did explicitly include my data in my form element as you can see in the 
above template.

The data is present as “ccEntry” in both home.html and in views.py.

django.db.utils.OperationalError: no such table: user_user

[cyril moreau]

Hi,

I have the following model that i use as AUTH_USER_MODEL :

model.py


class User(AbstractBaseUser, PermissionsMixin):
   email = models.EmailField(_('email address'), unique=True)
   password = models.CharField(_('password'), max_length=255, blank=False)
   first_name = models.CharField(_('first name'), max_length=30, blank=True)
   last_name = models.CharField(_('last name'), max_length=30, blank=True)
   date_joined = models.DateTimeField(_('date joined'), auto_now_add=True)
   is_active = models.BooleanField(_('active'), default=True)
   is_staff = models.BooleanField(_('staff status'), default=False)
   avatar = models.CharField(_('avatar'), max_length=30, blank=True, null=
True) 
#models.ImageField(upload_to='avatars/', null=True, blank=True)

objects = UserManager()

USERNAME_FIELD = 'email'
   REQUIRED_FIELDS = []

class Meta:
   verbose_name = _('user')
   verbose_name_plural = _('users')

settings.py
AUTH_USER_MODEL = 'user.User'


When i want to create a superuser and enter the email of the user i want to 
create :
python manage.py createsuperuser


I get the following error : 
django.db.utils.OperationalError: no such table: user_user

Someone knows why I get this error?

Thank you for you help

RE: Django credit card redaction app - - MultiValueDictKeyError

[Matthew Pava]

Please just paste the error in the email message. The error message that you 
have mentions a ‘method’ object, which is not present in the code that you have 
sent to us.  That would be where the problem is.

Re: Django credit card redaction app - - MultiValueDictKeyError

[Deepak Chhitarka]

In your home.html template, you forgot to write method="get" . Which I
think is causing the problem here.

Re: Django credit card redaction app - - MultiValueDictKeyError

[drone4four]

I am taking a course on Udemy and the instructor doesn’t include a method 
attribute in the form tag.  But as you suggested, Deepak, I went ahead and 
added method="get" to my form tag in my home.html template. So line 7 now 
reads: 

I am still encountering the MultiValueDictKeyError. 

Here is the traceback again:

Most likely an elementary fix

[Joseph Jones]

Good afternoon all!
I have been reading
https://www.packtpub.com/application-development/learn-python-programming-second-edition
since
November so I am very much new to the Python Community. I am currently on
Ch. 14 "Web Development" which indicates to complete the tutorial on
djangoproject.com after installing Django of course. when I've run the />
py -m django --version command in the cmd of my PC I receive a
ModuleNotFoundError. which the text in the tutorial states is an indication
that I did not install Django.  If I rerun /> pip install Django==2.1.7
however I receive "requirement is already satisfied Django==2.1.7" So it
would appear django is installed but my shell does not recognize it. I
hypothesize that I either:  did not configure my virtual environment
properly, or am pulling up the wrong folder in my cmd. Any advice on how To
fix this most likely Elementary mistake would be immensely appreciated. Let
me apologize in advance if I either ask for clarification in terminology of
any responses(again I am new) or mess up  again through out the course of
the tutorial and reach out to the community. Thank you!
Joseph

Trac is not yet released for Python 3.x. There is also a Subversion
server running via Apache2 so it looks like I need to keep Apache2
anyway.  I also have Buildbot running under Python 2.7 on that machine
but it runs on Twisted so I expect that will be a regular migration.

As a bonus question,  if this is even possible, would you
do-release-upgrade Ubuntu 16.04 to 18.04 before or after such a migration.

Thanks for any sympathy as well as advice.

Re: Is there a package for user-tagging and user-properties?

[Charles Thayer]

Thanks Simon,

I'm thinking of something more ad-hoc where key-value pairs can be attached 
to users, and the values might be simple strings, ints, datetime or other 
types.
I've started with just simple tags using django-taggit, but I'm still 
keeping my eyes open.

/charles
PS. $ pip search taggit:

You could try writing to Grahame Dumpleton for confirmation. I'm 
reasonably sure he wrote mod_wsgi and ought to be able to correct you if 
you've misunderstood anything.He used to give presentations on wsgi at 
PyCons so you might be able to find something on YouTube from a few 
years ago.


Last I heard of him he is fairly focused on Kubernetes so he probably 
doesn't monitor the Django list any more.

From what I've read, devs using Django don't need to be
too familiar with WSGI, but it seems like it helps at
least having a conceptual understanding of what it is.

This is how I think it works:

My example uses the most common setup I use:
Nginx, Gunicorn and Django

  * When an HTTP request comes in, it hits Nginx first
  o Nginx runs multiple processes, and makes
sure that browsers/clients that have a
slow connection don't effect other clients
  o If it's a request for a static file, like
a CSS file, JS, image, or anything like
that, Nginx returns it directly
  o If it's a request for anything else, it
uses *HTTP* to send the request over a
Unix socket to Gunicorn
  + Doesn't have to be a Unix socket, but
if both Nginx and Gunicorn are running
on the same host, it makes sense to
use Unix sockets
  + The main point is that Nginx uses HTTP
to communicate with Gunicorn
  * Gunicorn
  o Starts up x worker processes on startup
(as many as you tell it)
  o Each worker process imports your
application's code
(django.core.wsgi.get_wsgi_application()
in Django's case)
  + The application's code is a callable
function
  + Gunicorn imports it so that it's ready
to make a function call to it as soon
as an HTTP request comes in
  o When an HTTP request comes in from Nginx,
Gunicorn will:
  + Use its main process to assign the
request to a free worker process
  + The worker process translates the HTTP
headers into a python dictionary
(commonly called the 'environment'

There's a mod_wsgi_express thread that Graham monitors, so he's sure to get
feedback from there

Understanding this better could help me solve static file blues. Most of
the time I don't understand why my static files fine aren't served when I
move to production.

when I move to production.


Usually it is because they are in the wrong place.

Your production webserver (in my case Apache) probably wants to serve 
the static files directly without Django getting involved at all. There 
should be an alias directive in your webserver conf which specifies the 
actual location of your static files base directory and equates that 
with the STATIC_URL value in your settings. Similarly for the MEDIA_URL 
value.


All you really need to do is write a script to copy your static files 
from where they live in your dev environment to the location specified 
by STATIC_URL in your production environment.


Alternatively, manage.py collectstatic will do that for you.
