Thank you Sam :)

Do you have a separate users list for questions?

In case not, I'm trying to display a page produced with function-based 
views. Is there a hint you can offer?


I want the "View on site" button to produce pdf.

Maybe the real question is how do I change from function based views to 
class based views - which BTW I don't want to do.


Thanks

Mike

Re: Serving static files

[Ankush Thakur]

Hmmm. One argument I read supporting separate servers is that it would save
the main server a few socket connections. But this appears to be too little
of a gain. The approach of using a CDN, I think, is much more sensible.

Thanks once again, Tim!

Re: AUTH_PASSWORD_VALIDATORS not used when creating new users?

[Farhan Khan]

Even when I use User.objects.create_user() I am still not required to use a 
strong password. Considering that createsuperuser and changepassword are 
management commands, it seems odd that require a password that conforms 
with AUTH_PASSWORD_VALIDATORS there, but not with a function I would use in 
production code.

Re: Serving static files

The concerns about needing a separate server are likely overblown. In 
particular, Whitenoise is a popular solution for static file serving using 
Python. See its FAQ:

Re: AUTH_PASSWORD_VALIDATORS not used when creating new users?

[Tim Graham]

Validation happens in the management commands (createsuperuser, 
changepassword) as well as the user creation forms. We assume that if 
you're creating a user using the command line, you know what you're doing. 
If you want to open a documentation ticket, we could add a note about this.

Re: Contribute to Django - Python 3 or Python 2

[Tim Graham]

You can use either, but use Python 3. You can rely on the continuous 
integration server to test your pull request on Python 2 and debug any 
issues

Can you given an example of "most places python2 is used"? In fact, the 
tutorial says, "This tutorial assumes you are using Python 3."

Re: Contribute to Django - Python 3 or Python 2

[Farhan Khan]

I switched from Python2 to Python3 because I needed my Django code to fire 
off some TLSv1.2 code, that python2 could not do. I barely notice the 
difference between the two except in very small syntax differences. When I 
switched from python2 to python3, I literally did this:

find ./ -name "*.py" -exec 2to3 -w {} \;

And everything worked :)

I found it to have a more profound impact in other frameworks, such as 
Twisted or any type of socket programming, where you need to worry about 
encoding/decoding between unicode and binary strings.

Re: Django tests failing for development env

[Tim Graham]

If you're running the tests at the checkout point mentioned in the tutorial 
note, "If you’re using Python 3.5+, there will be a couple failures related 
to deprecation warnings that you can ignore. These failures have since been 
fixed in Django."

Contribute to Django - Python 3 or Python 2

[premdjango]

Hello,
Im trying to contribute to Django project and started with this document.

https://docs.djangoproject.com/en/dev/intro/contributing/

Here in couple of places I see Python3 is being used but in most places 
python2 is used.

Should I use Python 3 or Python 2?

Those were 2 different examples. In one case I started the container
with -p 8006:8000 and did:

runserver 0.0.0.0:8000

In the other case I didn't specify a the  -p 8006:8000 at all and did:

runserver 0.0.0.0:8006

I could not connect in either case.

I just tried the second case again with -p 8006:8006 but still no joy.

In the example you described, you launched runserver to listen on port
8006 inside the container, and then told docker to forward the host
port 8006 to port 8000 inside the container, but there's nothing
listening on port 8000 inside the container.

You'll want either to start the development server at port 8000 (and
keep the -p 8006:8000), or change the -p argument to 8006:8006.

Good luck,

Michal

running devel server in docker container

[Larry Martell]

I am trying to run the devel server in a docker container. On the
physical machine I don't have port 8000 available and I usually use
8006 for the devel server. Outside of the docker container I can
connect to 8006. Inside the container I tried both:

manage.py runserver 0.0.0.0:8006

and just manage.py runserver when starting the container with -p 8006:8000

But in both cases I cannot connect to the devel server at 8006. Anyone
know how to do this?

Tip: django-admin-easy

[Ezequiel Bertti]

Guys,

I did release a new version of django-admin-easy. Version 0.3

It is a collection of mixin, decorators and fields to be used on
django-admin.

It made what was already simple into something easy

Please, let me know if you have some suggestions, get some issue or want to
collaborate.

https://pypi.python.org/pypi/django-admin-easy

https://github.com/ebertti/django-admin-easy

Best regards

How to create the template "groups part" users admin. In my app?

[Fellipe Henrique]

Hello,

I have 2 model... Model A and B... Model A can has N records of B... That's
simple to do in django... But I want to build the HTML part.. Using the
same mechanism which django use on Groups... In one side show me all
records of B, and I can select one or more to add in A model...

How can I do that, using django admin?

I prefer not use inline..

Cheers!

Re: HTTP2 Server Push with Django?

[Bobby Mozumder]

No these are for push at the app layer, for functionality purposes.

HTTP/2 server push is meant for speeding up website responsiveness, by 
delivering static assets before the request for them are even made.

Getting "SMTPServerDisconnected: Connection unexpectedly closed: [Errno 104] Connection reset by peer" errors when using django.core.mail.send_mail in the loop

[Haomin Zhang]

Create a command like below, which send a mail to the user if the date meet 
the requirement:

class Command(BaseCommand):
help= 'Send mail to user regularly if there have contacts needs 
reminder'

def handle(self, *args, **options):
now = timezone.now().date()
backlogs = Backlog.objects.all()
for backlog in backlogs.iterator():
start_date = backlog.start_date
end_date = backlog.end_date
if start_date <= now and now < end_date:
user = backlog.user
user_email = user.email
user_name = user.username
if user_email is not None:
mail_title = u'Contracts need to be handling.'
mail_content = u"Dear:%s，you have messages" % user_name
link = u"http://xx.xxx.xx.xxx/contract-info/;
mail_content += link;
mail_from = 'from_em...@xx.com'
mail_to = [user_email]
send_mail(mail_title,
  mail_content,
  mail_from,
  mail_to)

This command can run well in local server. But when I launch it on the VPS 
and if call send_mail more than once, below mesasge appear:

"SMTPServerDisconnected: Connection unexpectedly closed: [Errno 104] 
Connection reset by peer"

But if only one backlog been filtered and only call once send_mail, it 
works well.

Does anybody met the issue before? thanks in advance!

wsgi setup + django 1.9 + python 3.5.1 on mac os x

[Coulson Kgathi]

I am getting an error trying to setup my django project on apache2 mac os 
x, django 1.9, python 3

my wsgi.py looks like this

import os

import sys


VIRTUALENV_PATH = '/Users/ckgathi/.virtualenvs/bcpp-interview/'

SOURCE_ROOT_PATH = '/Users/ckgathi/source'

LOCAL_PROJECT_RELPATH = 'bcpp-interview/'


# Activate the virtual env

activate_env=os.path.join(VIRTUALENV_PATH,'bin/activate_this.py')

# execfile(activate_env, dict(__file__=activate_env))

file_p = '/Users/ckgathi/.virtualenvs/bcpp-interview/bin/activate_this.py'

exec(open(activate_env).read(), dict(__file__=activate_env))

# Add the site-packages of the chosen virtualenv to work with

# update path

sys.path.insert(0, os.path.join(VIRTUALENV_PATH, 'local/lib
/python3.5/site-packages'))

sys.path.insert(0, os.path.join(SOURCE_ROOT_PATH, LOCAL_PROJECT_RELPATH))


os.environ.setdefault("DJANGO_SETTINGS_MODULE", 'bcpp_interview.settings')


from django.core.wsgi import get_wsgi_application

Re: wsgi setup + django 1.9 + python 3.5.1 on mac os x

[Avraham Serour]

it seems it doesn't have cffi installed

but why do you want to do this? are you using the mac as server of are you
setting up your development environment?

for development you may just use manage.py runserver, you don't need to
setup apache

for the server I recommend using nginx+uwsgi, the killer feature for nginx
over apache is the simpler config file

Re: Implementing user alias in django.

[ludovic coues]

I would separate user and account.
User is one person and is used to connect.
Account have newsfeed and follow other user.

Each user can manage as many account as he want.
Many user can manage the same account.

All that can be transparent to your user if you setup an account
matching the user for new account.

Re: django form data not saving to database

[kaustubh tripathi]

I removed 'default' attribute and replaced OneToOneField with ForeignKey of 
Post Model still it is not saving to database.
Do I need to override the save method as I did in Category Model.
If yes,then any solution??

Re: HTTP2 Server Push with Django?

The h2o server (https://h2o.examp1e.net) looks like it supports http/2 push, 
but it doesn’t have WSGI capability for Django.

Re: django form data not saving to database

[Luis Zárate]

models.OneToOneField(Category,default='category')

This is not set in form and not set in view and is not null so when you do
post.save() error was raised and post is not saved.

I don't sure that you can pass str as default for OnetoOne and I am not
sure that you need a OnetoOne field I think foreignkey us better for you,
because have not sense have one category for every post, I think you want
several post in one category.

Re: HTTP2 Server Push with Django?

let me know if any web server now implements "push" capability completely

Re: Best way to implement list pattern

Maybe with generic view


https://docs.djangoproject.com/en/1.9/topics/class-based-views/

Especially with

There is a lot information about how to implement what you need.

HTTP2 Server Push with Django?

[Bobby Mozumder]

Does anyone know of an http/2 server with server push capability that can work 
with Django?

It looks like nginx supports http2 with uWSGI, but it doesn’t actually support 
server push capability.

I also found the h2o server, but it doesn’t look like it supports uWSGI yet..

Any other options out there for http2 server push, preferably with cache-aware 
server push?

(I’d set http “Link” headers in my app to direct server push.)

Implementing user alias in django.

[Asif Saifuddin]

Hi,

I'm planning to implement user alias in django. A user can create many 
alias and each alias will work like and full user. each alias will have 
different newsfeed/user follow other user/alias and each alias can do every 
action a real user can do.

How should I implement this user model/architecture?

Thanks,

Asif

django form data not saving to database

[kaustubh tripathi]

Hi everyone!

I am creating a simple webapp using django where a user can login, choose 
one of the given category and create a post under the chosen category.

I am having trouble in creating a post. When I create a  new post through 
django form the date isn't saved to database. I log in to the django-admin 
to check if the post is created but the 'post' table remains empty.
 
Here are the necessary code snippets:

"Category model"
class  Category(models.Model):

name = models.CharField(max_length=128,unique=True)
slug = models.SlugField()
def save(self,*args,**kwargs):
self.slug = slugify(self.name)
super(Category,self).save(*args,**kwargs)

def __unicode__(self):
return self.name

"Post Model"
class Post(models.Model):
category = models.OneToOneField(Category,default='category')
title = models.CharField(max_length=128,null=True)
content = models.TextField(blank=True,null=True)

def __unicode__(self):
return self.title

"Postform/forms.py"

class PostForm(forms.ModelForm):
title = forms.CharField(max_length=128)
content = forms.CharField(widget=forms.Textarea)
class Meta:
model = Post
fields = ('title','content')

"create_post function/views.py"

def create_post(request,category_name_slug):

created = False
instance = get_object_or_404(Category,slug=category_name_slug)
if request.method == 'POST':
form = PostForm(data=request.POST or None,instance=instance)
if form.is_valid():
post = form.save(commit=False)
post.save()
created = True
else:
print form.errors
else:
form = PostForm()
context={
'form':form,
'instance':instance,
'created':created
}
return render(request,"add_post.html",context)


Any solution??
