[AF] SocketIO -- Server not opening websocket connection

Hi, I'm trying to run a (very) simple websocket server.

I'm trying to connect using a command line tool:
> $ wscat -c ws://localhost:5000/

Starting the server, and running the *wscat* request, I see:

* Serving Flask-SocketIO app "main"
* Forcing debug mode on
* Restarting with stat
* Debugger is active!
* Debugger PIN: 243-427-340

127.0.0.1 - - [24/Dec/2017 09:19:18] "GET / HTTP/1.1" 200 132 0.003266

It's making the http connection, but doesn't seem to be promoting to websockets. There's a debugging "print" doesn't print, and an "emit" that doesn't emit for the "connect".

I can use *wscat* to connect to echo servers just fine.

I'm clearly not doing something right, I'm just really not sure what!

I've tried with web pages too -- but here I'm trying to keep it simple.

I'd really appreciate another pair of eyes, if anyone has troubleshooting advice or can see a bug.

Thanks, and Happy Christmas!

EDIT:
I just tried running Miguel Grinberg's Flask-SocketIO off of github, but with the same environment I was running my own test with.

It works!

Though some of the responses are labelled polling, and some are websockets, which seems funny to me that it's doing both in the same browser.

But this confirms it's me not seeing / understanding some concept.

Jupyter Auto Starting in Atom Terminal

Not sure if this is the right place to post this but I thought I'd try.

Whenever I run the terminal in atom, it automatically starts a jupyter notebook. Not sure why this happens but its really annoying.

I also opened just a terminal window directly. It opened fine but this was the second line in the window:

env: jupyter-notebook: No such file or directory


Not sure what's going on here... Any help would be appreciated!

context in class-based views

So I recently switched to class based views, and found this code to pass in additional context to template:

class DetailView(generic.DetailView):
model = Language

template_name = 'languages/detail.html'

def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)

context['year'] = Details.objects.filter(year=2016)

return context

However, I fail to be able to display values/the variable in the HTML. How do i go about this in template.html?

The EULA states:

"No Datacenter Deployment. The SOFTWARE is not licensed for datacenter deployment, except that blockchain processing in a datacenter is permitted."

Django's autoreload function is unusably slow

Hello.

I have never had this problem in the past, but I am starting a new project and Django's autoreload feature (where it restarts the server after a code change) has been ridiculously slow (15 seconds - never). I am using WSL. I think this is something new with Django 2.0.

Django Rest API - writing to FK based

I have two models as below:

class University(models.Model):
name = models.CharField(max_length=50)

class Meta:
verbose_name = "University"
verbose_name_plural = "Universities"

def __str__(self):
return self.name

def __unicode__(self):
return self.name


class Student(models.Model):
first_name = models.CharField(max_length=50)
last_name = models.CharField(max_length=50)
university = models.ForeignKey(University, on_delete = models.SET_NULL, null = True)

class Meta:
verbose_name = "Student"
verbose_name_plural = "Students"

def __str__(self):
return '%s %s' % (self.first_name, self.last_name)

def __unicode__(self):
return '%s %s' % (self.first_name, self.last_name)



class UniversitySerializer(serializers.ModelSerializer):
class Meta:
model = University
fields = '__all__'

class StudentSerializer(serializers.ModelSerializer):
university = serializers.SlugRelatedField(slug_field = 'name', queryset = University.objects.all())

class Meta:
model = Student
fields = '__all__'

I want to be able to access the forms that are generated by the browsable API in angularJS or any of the front end frameworks.

Can someone please nudge me into the right direction?

It's something most likely very simple however, I am lost as I am very new to this.

Many thanks in advance
