- Sample script that starts up Flask microframework
- Sample Bokeh plotting script should draw a circle
- The circle plot should be visible in the
plot.htmltemplate - The
plot.htmltemplate is rendered with a request to the root dir ('/')
- Assumptions: you have
virtualenvandpipinstalled - Build a virtual environment
$ virtualenv venv-name
- Activate the venv
$ cd venv-name
$ source bin/activate
- Clone the repo
$ git clone https://github.com/robnewman/bokeh-test
- Rename
bokeh-testtowww
$ mv bokeh-test www
- Change directory to
www
$ cd www
- Load everything from REQUIREMENTS file with
pip install -r REQUIREMENTS.txt
- From the command line:
python run.py
- Dynamically created JS files written out to
static-flask-bokeh/js/tmp/
- Dynamically created Bokeh plots displayed at root page
http://127.0.0.1:5000/
- Dynamically created JS files written out to
static-flask-bokeh/js/tmp/
- Here is the directory structure after running the server and hitting it a few times:
$ tree static-flask-bokeh/

</html>Look at the <script src=""> path. It is a relative link. If I click
on that link I see a 404 error. That shouldn't be.
Either Flask or Bokeh does not look in the specified TMP directory.
Looks like a root_url or root_dir problem in the Bokeh Resources() class?
