Bokeh autoload_server() implementation

Hi all,

This is possibly a trivial question, but I’m new to Bokeh and I have essentially no experience with html or javascript.

I have a standalone Bokeh server running at localhost:5006 and works perfectly fine when accessed directly. But I’d like to implement user logins via django. I’ve been able to set up a django server, but I am missing something. I do not see any Bokeh server activity when accessing the the django app (not even a websocket rejection), so I’m leaning towards html syntax being the issue? An (unauthorized) example i found had instead of what i posted below, but that didn’t work either.

I’ve also tried hard-coding an autoload_server() return into the template, but that did not work either.

Any advice is greatly appreciated. Thanks!!

Hi Dan,

it looks like you are missing some arguments in the bokeh autoload_server()

Here is my solution to embed a bokeh app in django templates, this is using bokeh 0.12.4 though - I know that autoload_server() has changed in 0.12.5 but I haven’t had time to update yet.

urls.py

https://github.com/lsst-sqre/qa-dashboard/blob/master/squash/dashboard/urls.py#L27

views.py

https://github.com/lsst-sqre/qa-dashboard/blob/master/squash/dashboard/views.py#L186

embed_bokeh.html template

https://github.com/lsst-sqre/qa-dashboard/blob/master/squash/dashboard/templates/dashboard/embed_bokeh.html#L25

hopefully this example helps.

PS.: at some point I would like to provide a minimum code example for this integration, let me know if you (or somebody) is interested.

best,

Hi Dan,

glad you solved your problem. I have to update to 0.12.5.

Another thing that might be of interest if you are embedding bokeh apps in django is how to pass url parameters from one bokeh app to another.

You have to do that through django so that you can embed the second app.

My solution for that was to set a cookie in the HTTP Response of the first bokeh app with the full django url

https://github.com/lsst-sqre/qa-dashboard/blob/master/squash/dashboard/views.py#L206

then the second bokeh app can recover the url parameters from the bokeh server HTTP Request and set its state.

Example:

https://github.com/lsst-sqre/qa-dashboard/blob/master/squash/dashboard/viz/api_helper.py#L185

and

https://github.com/lsst-sqre/qa-dashboard/blob/master/squash/dashboard/viz/AMx/main.py#L22

Hi Dan and Angelo,

I’m currently working on something similar, thanks to both for posting your examples. Dan, did you do as Angelo and run a shell script separately to run bokeh server alongside Django? I saw the examples in the docs to launch the server with tornado and ioloop, but for me it seemed like to implement in Django I would incorporate the code after `if name == ‘main’ in manage.py.

Right now for development, I’m running python manage.py runserver 0.0.0.0:8000 to get django running, then in a separate window I run bokeh serve … as Angelo did. I’m not very familiar with running shell scripts, is it common in production to run the two shell scripts as daemon processes? If done this way, is the number of servers equal to the number of arguments, independent of the number of requests? Is it normal to not have a new bokeh server for each request (or user/visitor)? Please feel free to set me straight if I’m mixing up terminology.

Thanks!

Dan

Hi Dan,

I manually start my Bokeh and Django servers separately. Scripting it sounds like a good idea, but I haven’t looked into it… I’m also not even remotely an expert, so don’t take my word.

You shouldn’t need a new bokeh server per request. One Bokeh server can handle that for you. Basically, my Django server just provides a gate to my Bokeh server. I only allow my bokeh server to be accessed by Django traffic. However, this isn’t entirely secure. I should really be implementing additional security measures.

I manually start one Bokeh server (per Bokeh app) and one Django server.

Hope that helps… or prompts a smarter person to help you :slight_smile:

Dan

hopefully this example helps.

This is possibly a trivial question, but I’m new to Bokeh and I have essentially no experience with html or javascript.

I have a standalone Bokeh server running at localhost:5006 and works perfectly fine when accessed directly. But I’d like to implement user logins via django. I’ve been able to set up a django server, but I am missing something. I do not see any Bokeh server activity when accessing the the django app (not even a websocket rejection), so I’m leaning towards html syntax being the issue? An (unauthorized) example i found had instead of what i posted below, but that didn’t work either.

I’ve also tried hard-coding an autoload_server() return into the template, but that did not work either.

Thanks. I have bokeh server and django running simultaneously now:

bokeh serve --allow-websocket-origin=localhost:8000 test_app/test_calc

(There is a bokeh app contained in main.py in test_app/test_calc)

Django is running on 192.168.56.10:8000 and my pre-existing routes are working.

I have a url route for ^bokeh_test/ mapping to a view:

class BokehTestDash(TemplateView):

template_name = ‘bokeh_test.html’

def get_context_data(self, *args, **kwargs):

from test_app.test_calc import main # was getting an error ‘parent module not imported’ without this line

context = super(BokehTestDash, self).get_context_data(**kwargs)

context[‘script’] = autoload_server(url=‘http://localhost:5006’)

And my bokeh_test.html file has simply:

{% extends ‘base.html’ %}

{% block content %}

{{ block.super }}

Bokeh Test

{{ script|safe }}

{% endblock content %}

When I navigate to 192.168.56.10:8000 or 192.168.56.10:8000/bokeh_test, the page loads with the “Bokeh Test” header, but nothing else loads. In the log I can see a deprecation warning that I know is coming from my bokeh app at main.py, but nothing is resolving on the page.

Any guidance out there would be greatly appreciated!

Hi Dan,

I manually start my Bokeh and Django servers separately. Scripting it sounds like a good idea, but I haven’t looked into it… I’m also not even remotely an expert, so don’t take my word.

You shouldn’t need a new bokeh server per request. One Bokeh server can handle that for you. Basically, my Django server just provides a gate to my Bokeh server. I only allow my bokeh server to be accessed by Django traffic. However, this isn’t entirely secure. I should really be implementing additional security measures.

I manually start one Bokeh server (per Bokeh app) and one Django server.

Hope that helps… or prompts a smarter person to help you :slight_smile:

Hi Dan and Angelo,

I’m currently working on something similar, thanks to both for posting your examples. Dan, did you do as Angelo and run a shell script separately to run bokeh server alongside Django? I saw the examples in the docs to launch the server with tornado and ioloop, but for me it seemed like to implement in Django I would incorporate the code after `if name == ‘main’ in manage.py.

Right now for development, I’m running python manage.py runserver 0.0.0.0:8000 to get django running, then in a separate window I run bokeh serve … as Angelo did. I’m not very familiar with running shell scripts, is it common in production to run the two shell scripts as daemon processes? If done this way, is the number of servers equal to the number of arguments, independent of the number of requests? Is it normal to not have a new bokeh server for each request (or user/visitor)? Please feel free to set me straight if I’m mixing up terminology.

Thanks!

Hi Dan,

glad you solved your problem. I have to update to 0.12.5.

Another thing that might be of interest if you are embedding bokeh apps in django is how to pass url parameters from one bokeh app to another.

You have to do that through django so that you can embed the second app.

My solution for that was to set a cookie in the HTTP Response of the first bokeh app with the full django url

https://github.com/lsst-sqre/qa-dashboard/blob/master/squash/dashboard/views.py#L206

then the second bokeh app can recover the url parameters from the bokeh server HTTP Request and set its state.

Example:

https://github.com/lsst-sqre/qa-dashboard/blob/master/squash/dashboard/viz/api_helper.py#L185

and

Hi Angelo,

I am wondering if there is anything that changed on server argument, server_session, or server_document changed on bokeh 1.0.0. I was following the online tutorial on how to use bokeh on Django. However, I keep on getting the same error.

I really appreciate if someone can point me in the right direction how to start my bokeh server in Django on bokeh 1.0.0

Thank you,

I’ve also tried hard-coding an autoload_server() return into the template, but that did not work either.

Any advice is greatly appreciated. Thanks!!

def dvh_viewer(request):
 script = autoload_server()
 t = TemplateResponse(request, 'dvh/dvh_viewer.html', {"script": script})
 t.render()
 return t
