running a python function in bokeh when clicking on a button

Hello,

I would like to know if it is possible to use a button in bokeh to call a python scrip i.e. to run a function in python that would generate an excel without having to use CustomJS in callback ?

If you have any example to I could look at, that would be great.

Thanks a lot for your help !!

Best,

Patrick

Hi Patrick,

A lot depends on the context you are running Bokeh in. If you are rendering a visualization as an html page your options are limited to Javascript. If you are running Bokeh in a server, you have many more options obviously. Check out the documentation on the Bokeh server for details on server side callbacks:

http://bokeh.pydata.org/en/latest/docs/user_guide/server.html#callbacks-and-events

And if you are running Bokeh as a stateless app in Flask or Django (or any others) you can always define an endpoint that collects the results of your data viz (filters, sliders, datatables, etc.) and creates an excel file on the Python end.

If you can provide more details on your project I’m sure someone can help steer you in the right direction.

cheers,

Dennis

I am running the code inside a bokeh server.

I am using a drop-down widget menu to select a value that I am getting back using the widget_menu.value.

I would like to have a button that will trigger a python function when I press it.

That function is running a scrip on its own with one parameter being the widget_menu.value.

That function will generate an excel outside of the bokeh server.

Cheers,

Patrick

Hi,
I found a way creating a button and button.on_click(update_button) where update_button is a function containing the function I wanted to run.

Problem solved.

Thanks.
