Multiple projects, shared auth, single sign-on

Im trying to determine how to best structure multiple django apps on subdomains, so they can share user account data. One user account works across 2 subdomains, ideally single-sign on.

I understand we can use SESSION_COOKIE_DOMAIN to share the session cookie, that part seems ok.

And I understand we could simply use shared user tables, and set user model to point to table of another project. But it seems we would want to share code between the projects. Should we have a separate User app in a third repo?

I have seen django-mama-cas , does anyone have experience with it? Or any alternatives?

Flask, uWsgi, nginx and errors logging

How do I turn on error logging.
I have a service starting my app.

[Unit]
Description=uWSGI instance to start the site
After=network.target

[Service]
User=me
Group=me-group
ExecStart=/usr/bin/env bash -c 'cd /www/web_projects/site_app/; uwsgi -- /www/web_projects/site_app/start_site.ini'
logger=/log/site_app_log.log
[Install]
WantedBy=multi-user.target

I have turned on logger. Which does create the file. But it does not write anything to the file.

nginx setup looks like the following.

location / {
proxy_pass http://127.0.0.1:8080;
}

When I start the site using the command line, I get the error writing to the console. But when the service starts the site I do not get any errors. Where and how to I log the errors?

Thanks.

Reusable snippets with dRY Views?

I have a model for News (Info). The News is displayed on a few pages in an accordion style div. So as to not violate DRY, I placed the HTML for News in a separate file and use the {% include %} tag. It is wonderful.

But what I can't figure out is keeping DRY with my views. To show the news I use (truncated):

def get_context_data(self, **kwargs):
context = super(About, self).get_context_data(**kwargs)
context['newslist'] = Info.objects.filter(priority=0).order_by('reported_on')
context['important_news'] = Info.objects.filter(priority=1).order_by('reported_on')
return context

For each page that uses News, I've been re-copying the code into that page's View. Is there a way to do this and still keep DRY? Or am I overreacting? Or both?~~~~

[AF] Swagger API [connexion] behind nginx(using gunicorn) using allow rules and ufw(Uncomplicated Firewall) rules.

From: https://gist.github.com/Morabaraba/06403358de009ede60e1d842c48100b7

So I have a wonderful Swagger API implemented in flask using connexion and sqlalchemy.

It is only a B2B(Business to Business) app. At the moment I have a `allow` rule for each client in `nginx` and use ufw on the cli:

```
ufw allow proto tcp from 42.42.42.42 to any port 1334
```

But instead of changing conf files and executing ufw commands manually, I would like to automate it.

I feel a simple `user_ip_address` table with a restful crud api will work:

```py
class user_ip_address(db.Model):
__tablename__ = 'user_ip_address'
user_id = db.Column(db.Integer)
ip_address = db.Column(db.String)
```

You call `/api/set-user-ip-address` with a `authorization` header identifying the user and the ip address in the `POST` body.

But at this point do I do a ugly:

```py
system.os('ufw allow proto tcp from {} to any port 1334'.format(ip))
```

and

```py
system.os('echo "allow {}" >> /etc/nginx/sites-enabled/h4ck3webapp.conf && service nginx relead'.format(ip))
```

While it might work it feels like a hack of hacks.

I'm now going to dive a bit deeper into nginx allow rules and uncomplicated firewall docs.

But I just need to bounce the idea. Coding in a bubble is not fun.

[AF]WTForms-JSON Form Not Posting Data

[WTForms-JSON docs here.](https://wtforms-json.readthedocs.io/en/latest/)

This has been a bug from hell I cannot wrap my head around.

I have a simple API handler that works perfectly fine from Postman JSON POSTs.

However when I plug the data into a web form the JSON is all empty. For example:

162.249.161.234 - - [23/May/2017 10:52:59] "GET /?customer=test+customer HTTP/1.1" 200 -
{'customer': None}

My Flask is as follows:

@app.route('/')
def index():
form = SubmitWorkorderForm.from_json(request.json)
print form.data
return render_template('submitworkorder.html', form = form)

@app.route('/submitworkorder', methods=['POST'])
def submitworkorder():
form = SubmitWorkorderForm.from_json(request.json)
print form.data
if form.validate_on_submit():
customer = form.customer.data
return jsonify({'customer' : customer })

And my HTML:

<div class="container">
<form class="form-inline">
{{ form.customer }}
{{ form.hidden_tag() }}

<input type="submit" value="go"/>
</form>
<br>
<div id="successAlert" class="alert alert-success" role="alert" style="display:none;"></div>
<div id="errorAlert" class="alert alert-danger" role="alert" style="display:none;"></div>

Lastly my JS:

$(document).ready(function() {
console.log("form Data:", $('form').serialize())
$.ajax({
type: "POST",
dataType: "json",
url : "/submitworkorder",
data : $('form').serialize(),
success: function (data) {
if (data.error) {
$('#errorAlert').text(data.error).show();
$('#successAlert').hide();
}
else {
$('#successAlert').text(data.customer + 'successfully created.').show();
$('#errorAlert').hide();
}
}
});

});

I have been working on this for the better part of 8 hours with no progress at all. Any help is appreciated.

I took my Django HyperText Coffee Pot Control Protocol Middleware implementation and released it as my first ever package on PyPi, would love to get some feedback and critique.

Here's the link to the package:
https://pypi.python.org/pypi/django-htcpcp/0.2.1

and here's a link to the github repo:
https://github.com/dashdanw/django-htcpcp

I tried to make it compatible for django 1.8-1.11 and python 2/3 and I would love to hear some feedback on code style and if it's actually working, or anything else I can do to make it a stable package.

This one is sort of a novelty but in the future I would like to start developing more libraries so any advice whatsoever, even if it may seem like overkill for a package this small, would be useful to me.

Kernels in Docker Containers?

Hey, has anyone experimented with using docker containers as kernels? For example, you might spin up a docker container running a python3 kernel, but within the container you have some additional software resources that you can access with Python's subprocess calls.

How do I handle %20 into spaces for a django filter for queries?

class SomeFilter(filters.FilterSet):
class Meta:
model = SomeModel
fields = {
'column1': '__all__',
'column2': '__all__'
}
So basically lets say I have a GET request using this filter like www.someAPI.com/?column2=something%20or%20Another

When I apply the filter above, it doesn't work because it's querying column 2 with %20 instead of spaces (which is what is in the sql database) how can I handle this so it queries correctly?
