Bokeh DataTable in Flask: Bokeh Error Model `StringFormatter' does not exist.

Community Support

I get the following error in my browser when I try to include tables in the bokeh layout using flask:
x

Bokeh Error

Model `StringFormatter' does not exist. This could be due to a widget or a custom model not being registered before first usage

This is how I turn my pandas DataFrame into a bokeh table:

df = df_func()

df.reset_index(inplace=True)

df.rename(columns={“index”: “Typ”}, inplace=True)

source = ColumnDataSource(df)

table1_columns = [ TableColumn(field=“Typ”, title=“Typ”), TableColumn(field=“Betrag”, title=“Betrag”),

TableColumn(field=“Trend”, title=“Trend”) ]

table1 = DataTable(source=source, columns=initial_columns, width=500, height=280)

I then combine the table with two (working) plots into a single layout:

layout = vplot(row(plot1, plot2), row(table1))

script, div = components(layout, )

My HTML file looks like this:

BokehTest

{{ div | safe }}

{{ script | safe }}

I also tried it with the {{ script | safe }} inside the .

I get the following three erros inside my browser (one at a time):

Model `DataTable’ does not exist (…)

or

Model `StringEditor’ does not exist. (…)

or

···

Model `StringFormatter’ does not exist. (…)

You need to also load the bokeh-widgets-0.12.4.min.[js|css] files for CDN in your template, as described here:
