I am trying to embed a Bokeh plot in a Django site that has a download button on it. I use the example here here as a starting point, and then adding the implementation instructions from here . This is a continuation of my question here , since I now have a new problem. The plot just doesn't appear when I go to the URL associated with it, but there is no error message and the page loads.
I used need-a-minimal-django-file-upload-example/for_django_1.8and it works as intended when I go to the URLhttp://<port>/myapp/list/
myapp/url.py as follows
from django.conf.urls import patterns, url
from . import views
urlpatterns = patterns('myproject.myapp.views',
url(r'^list/$', 'list', name='list'),
url(r'^simple_chart/$', views.simple_chart, name="simple_chart"),
)
views.py simple_chart.html. http://<port>/myapp/simple_chart/, simple_chart .
views.py
