Re: Where is django-admin?

[Pelle Pälsänger]

Yes, I have done that and made (myvenv) 
C:\Users\stig\djangogirls\myvenv\Scripts>django-admin.py startproject 
mysite . , but no djangogirls\mysite created.
My django-admin looks like below. Maybe something should be added to make 
it work?

#!c:\users\stig\djangogirls\myvenv\scripts\python.exe
from django.core import management

if __name__ == "__main__":
management.execute_from_command_line()

Re: port 80 **** Hit EOF while fetching headers

Hi,

With an average of 150 requests per second, it is likely that your server is
overloaded. You need to examine the available memory and CPU usage.

Re: about tutorial "app reusable section" issue

['Abraham Varricatt' via Django users]

Hello Xuanbei,

You are most likely getting that erro because you still have 'polls' 
mentioned inside INSTALLED_APPS within your settings.py file. 

On a different note, can you link to the tutorial you are following? I 
don't recall the official django tutorial instructing to install polls via 
pip. Instead, the tutorial teaches you to build the polls app.

Yours,
Abraham V.

Re: Make a separate table for a model without additional fields

Why do you need an additional model for automatic payments?

I don't know the whole project, but I would just add a field to the
Payment class

Make a separate table for a model without additional fields

[Victor Porton]

I store into the DB payments received through PayPal. Every payment is 
either manual or automatic (automatic payments are done for the user by 
PayPal automatically, based on user's permission to pay in the future). I 
wish to distinguish manual and automatic payments in the DB. But in the 
following code both regular payments and automatic payments share the same 
table, so that they cannot be distinguished. I ask for an advice how to 
make them distinct in the DB. The best thing I invented insofar is to add 
`dummy = models.SmallIntegerField()` to AutomaticPayment class, to allocate 
a new table for it. Are there better ways?

class Payment(models.Model):
transaction = models.OneToOneField('BaseTransaction')
email = models.EmailField(null=True)

class AutomaticPayment(Payment):
pass

By the way, it is an open source project, so you will benefit from my work.

Re: Django feedback

Can you successfully send an email from the command line on your server?
You need to be able to do that in order to send email from django.

Re: Django Channels App Design

[Ethan Knapp]

Thanks Andrew! I'm glad I'm not the only guy out there with a similar 
problem. I'll have to look into the feasibility of the database approach, 
but I'm not sure if it will be efficient enough - I have some data points 
that require faster resolution than every second.

port 80 **** Hit EOF while fetching headers

[zhenwuhe0611]

Hi, Experts:

We built our system using apache + django and we have lots of clients 
sending updates to our backend server at around 1min interval. But we do 
have 9000 around devices. From time to time, we are seeing port 80  Hit 
EOF while fetching headers in apache log or 500 error, could anybody tell 
me what does this mean and what maybe the possible reason to cause this? or 
any suggestion what I could do to isolate what cause this issue.

thanks in advance.

Django Sass verwenden

[Jonas Niedermair]

Ich habe vor einiger Zeit begonnen Django zu lernen. Bisher habe ich immer 
direkt CSS verwendet. Ich möchte jedoch Sass verwenden, weiß jedoch nicht 
wo ich die Sass Dateien in meinem Django Projekt speichern soll und wie ich 
die Sass Datein am besten in CSS konvertieren kann. 

Ich habe bereits versucht mit Pipeline die Sass Dateien in CSS zu 
konvertieren. Das hat auch funktioniert, aber wie schaffe ich es dass die 
CSS Dateien nicht nur im static Ordner des Projektordners sondern im static 
Ordner der jeweiligen App gespeichert werden ?

Ich hoffe ihr könnt mir weiterhelfen

Re: Error was: cannot import name 'GDALRaster in Window 8.1

[Tim Graham]

It looks like GDAL isn't installed on your system.

Looking at 
https://docs.djangoproject.com/en/stable/ref/contrib/gis/install/#spatial-database,
 
I believe it's a required dependency -- perhaps we should try to improve 
the error message.

If you opensource it and host the code on github - you can easily setup

This tells you that id is not handed to the template that 
renders the view containing this form. Otherwise, arguments 
would be '('123456',)'.

No, it MUST not. That just changes the problem from args to 
kwargs.

Django package boilerplate.

[Frederik Creemers]

I've got a few utilities in my app that I think could be useful to share as 
open source projects, but I'm putting it off because I'd have to set up CI 
for multiple Python/Django versions and other boilerplate. Is there a 
boilerplate repository for sometHing like this out there that I can ust put 
my code into, and configure to run my tests?

Split an existing app up into multiple apps.

[Frederik Creemers]

Hi.

Is there a guide on how to split up an existing Django app into multiple 
apps?

When I created my project, I foolishly created an app called "common". 
Generic names like that attract all sorts of functionality, and now I think 
it'd be a good idea to split it up.

Re: Django Tutorial | sqlmigrate command ending in error

Ok..Sorry about that. 

I haven't done any modifications to  polls/migrations/0001_initial.py or 
settings files that got created by default.  I've attached both files.
Please review.

Thanks,

Different models in child and Parent Templates

[jithu s jacob]

I am using parent template as base which has a side nav bar. the child 
template keeps changing with clicking of buttons.
 
My child template changes correctly with call to different views through 
the URLs.

Now I want to add some data from model i the parent template irrespective 
of the view/model  or URL being called in the child template.

is there any easy was to do this.

for now I am writing additional context variables for parent template for 
all the child views. But this is not feasible
