DatePicker value change

Community Support
1

I want to update the value of DatePicker widget.

time = widgets.inputs.DatePicker(title=“Time”, value=‘2015-11-01’)

print time.value gives ‘2015-11-01’

time.value = ‘2014-11-01’

print time.value gives ‘2014-11-01’

``

but on webpage the value doesn’t update. The same problem arises when you change min_date, max_date. The value in object changes, the value on screen doesn’t.

I use bokeh-0.12.7.dev11

Hi,

Can you please provide a complete script that can be run and tested?

Thanks,

Bryan

Hi,

here it is

from bokeh.layouts import widgetbox

from bokeh.models import widgets

from bokeh.plotting import curdoc

def change_time():

print 'previous values: ', time.value, time.min_date, time.max_date

time.value = '2015-11-10'

time.min_date = '2015-10-01'

time.max_date = '2015-12-30'

print 'changed values: ', time.value, time.min_date, time.max_date

return 0

time = widgets.inputs.DatePicker(title=“Intervention”, value=‘2015-11-02’, min_date=‘2015-11-01’, max_date=‘2015-12-01’)

button = widgets.Button(label=“Change time”, button_type=“success”)

button.on_click(change_time)

layout = widgetbox([time,button])

curdoc().add_root(layout)

``

by clicking the button the time in widget must change, it does not.

Best,

Hi,

This appears to be a case of some missing plumbing. Hopefully an easy fix, here is an issue you can track (slated for the next release)

  Set initial date in date picker in models/file/widgets · Issue #6546 · bokeh/bokeh · GitHub

I'm afraid I don't have a workaround to suggest at this time, short of creating your own custom extension.

Thanks,

Bryan
