Re: Chart library for django

2017-03-05 Thread Lachlan Musicman

Hi Luvpreet,

There's nothing built into Django. Django is a web framework and charts are
outside of that. Django is written in Python and uses the standard web
technologies like HTML, CSS and JS.

You will need to find a charting package that can be used with any of those
and work out how you want it to plug in.

One option is to utilise the REST framework (
http://www.django-rest-framework.org/ ) to present data and use something
else to slurp in the results of that. Or ggplot or d3 as mentioned
previously.

But to answer your question, no, Django does not have a built in charting
package.

cheers
L.

Chart library for django

2017-03-05 Thread Luvpreet Singh






Hi everyone,

I am looking for some solution to display django database queryset to 
django admin over graphs.
I had used highcharts to do that earlier, but to use highcharts, I have to 
write too much scripts and functions.

Is there any kind of inbuilt library that comes with django similar to 
highcharts by which I can display django database queryset in my django 
admin template ?

Like in the picture above.

Re: Channels - slow with limited number of connections

2017-03-05 Thread Andrew Godwin

If your channels get full it means your workers aren't draining the
channels fast enough - you should spin up more workers. At some point you
also need to increase the channel capacity as well to smooth out bumps, but
the channel capacity only needs to be about the same as the number of
requests per second - it's 100 by default.

That depends on your workflow. You can fill the form using an Ajax call, yes. 
But - you 
don't have to.[1]

The above is part of code I'm working on. I am actually working on handling 
duplicated 
form media in the AdditionalFormsManager, so it certainly isn't production 
quality yet - 
but it will work just fine for illustration purposes or base for your own code.

No

And i just realized that expiry=5 is wrong because it disconnects users.

im using asgi_redis, and somehow it's better since i changed settings to:

channel_layer = RedisChannelLayer(
capacity=1000,
expiry=5,
)

but i still dont have idea whats correct. I would like to explain what im 
trying to achiev. I have website for matchmaking of dota 2 lobby games. 
When 10 players are finding match, ready check is sent and when everyone is 
ready then Steam bot starts and hosts the game...Bot must run entire time 
when players are playing so it needs one worker for each game played...Its 
why i cannot have only 2 workers or so i guess...because when there is more 
than one game workers are busy.

Python threads are not that great at sharing I/O - I'd recommend you run at
most one or two per physical CPU core in your machine. 500 is just going to
suffocate Python in context switching.

We have loadtests that definitely got above 10 messages a second - what
ASGI backend are you using? What size messages are you sending? Have you
tried running workers in separate processes?

Re: new to Django

2017-03-05 Thread ludovic coues

If you haven't done so, you should do the django tutorial. It will
give you a good view of what is available to django user.

Then there is a few page in the documentation about contributing.
https://docs.djangoproject.com/en/dev/internals/contributing/

What you'll need to learn depend on what aspect of django you want to
contribute to. But networking and GUI shouldn't be needed beyond some
basic knowledge. Django is a framework for building the server side of
web application. It provide really few GUI components and the
networking stuff is delegated to real webserver like nginx.

Re: How do you populate an update form in a Bootstrap Modal?

Hi Michael,

> I am trying to figure out how to populate the update model form in a

Look at how ModelFormMixin[1] does it:
 1. get_content_data from FormMixin calls get_form()
 2. this gets the form class and calls get_form_kwargs()
 3. ModelFormMixin injects the 'instance' keyword argument for the ModelForm
So, in order to prepopulate the form in the modal you need to provide the 
instance 
argument and assign it the model instance. I assume you know what model 
instance 
you need to update.

But the iframe still loads /interactive. So it's base url is /interactive and a 
request for scripts/main.js is /interactive/scripts/main.js.

Unless you either:
1/ Do a redirect, which is the simplest
2/ Request your resources incorporating the session id

I still would go for 1/, simply because that fixes the disconnect between 
template path / view path and requested url.

Sorry, I forget to mention it is to replace email =
models.OneToOneField in UserProfile. Or more exactly, add the
related_name argument to the email field.

Writing your first Django app, part 4

2017-03-05 Thread friscosoftware

I'm in the process of learning Django and working throught the tutorial, 
Writing 
your first Django app . I'm 
getting stuck on part 4.  The form n detail.html doesn't display radio 
buttons.  Thus there is nothing to select and when I submit the form, I get 
the message, "You didn't select a choice."

Thoughts?

Thanks,
Phil

Re: can i use the listview which the django-admin used im my tempate

2017-03-05 Thread Andréas Kühne

Hi,

I don't really understand what you mean, but there is a ListView in the
generic views package. To use that all you really need to do is to tell the
listview class what model you are using. For example:

class UserList(ListView):
model = User

You can see the information about the view here :
https://docs.djangoproject.com/en/1.10/ref/class-based-views/generic-display/#listview

Andréas

Re: Channels - slow with limited number of connections

2017-03-05 Thread Avraham Serour

I don't think you need 500 workers, the number of workers depends on how
long will message will take to be processed not the number of concurrent
connections.

The worker job is to get a message and send to a bunch of clients, the ASGI
server, meaning the process actually holding the websocket, in your case
daphne, will actually upload the data.

Is the client and server running on the same computer?

Don't stress test your server manually, you should write a script to do it.

templatetags for easy to edit content

2017-03-05 Thread John Wieland

Hi Everyone,

I've written a template tag that looks up an object and returns a field. 
For instance:
@register.simple_tag
def content(name):
return mark_safe(Content.objects.get(name=name).content)

These tags are used to make it easier to edit content on the site. I just 
need to add a {% content "about" %} to the template and modify the object 
in the admin console. The above is a simple example, there are some error 
messages displayed if the object is not found, but I'd like to do something 
else to make it easier to see what content needs to be written by iterating 
the templates to find where this tag has been used and creating the objects 
needed.

My idea was to monkey patch the templatetags to create the empty objects 
and then iterate over all the templates calling render_to_string() for 
each. The monkey patching would look something like this:
def create_content(name):
   if not Content.objects.filter(name=name).exists():
 content = Content()
 content.content = "Fill in %s" % name
 content.save()

   return ""

app.templatetags.content = create_content


Should this work? I haven't been able to get the 'create_content' function 
to execute when running my initialization script. I've also tried 
re-registering the tags with the same name.

Is there a better way to implement the functionality (either the editable 
content or the initialization process)?

Thanks,
John

Channels - slow with limited number of connections

2017-03-05 Thread Lada B

Hi, im using django-1.10 + channels + asgi_redis + daphne + uwsgi + nginx 
but i have problem with workers+daphne being slow. 

Im developing chat and I tried how fast its by holding ENTER button 
(spamming messages one after one and it doesn't even respond until i stop 
sending messages.

When i try to test performance (sending message to websocket every 10 ms) i 
get kicked after 5 seconds..when i try to do it every 100 ms, nobody else 
can connect. I checked CPU usage and when i set runworker --threads 500 
there is running like 250 threads of workers...when i set 10 threads then 
its like no way to use it

Am I doing something wrong? Why are workers so slow in processing of one 
websocket message that is empty string?

Re: Hello I am new to django

2017-03-05 Thread ludovic coues

You should look at the related_name argument of relationship. Using `
models.OneToOneField(CustomUser, related_name='profile')` will add a
profile property to your custom user object.

Then your function became something like that :

def get_full_name(self):
full_name = '%s %s' %(self.profile.first_name, self.profile.last_
name)
return full_name.strip()

Don't forget to write some test and to take into account what happens if
you user have no UserProfile associated

Re: Issue using django-admin

if you are new to django you don't want to download the development 
edition, this is more for contributing

firstly you need pip.

secondly, do your self a huge favour and install virtualenv and read the 
getting started docs now rather than later

once you have made a virtualenv directory and made it your current 
directory, you with need to activate the environment.

run pip install django

you shouldn't have a problem from here running the relevant django commands

at the start of you index.html add:

{% load staticfiles %}

and then when adding you scripts use:
