In my app I’m changing table values based on GIS data selected earlier in the application process. The updated values are read from a JSON file.
I can successfully change the table data with the callback below but it is not changing the State of the data. I can tell because I have another callback that later reads ine table States and prints the data to a JSON file.
If I manually edit the editable table then the State changes and I can see this with the JSON output file.
How do I change the State 'data’
@app.callback( [Output(weather_table_id, 'data'), Output(tds_table_id, 'data')], [Input('initialize', 'children')], [State(weather_table_id,'data'), State(tds_table_id,'data')] ) def update_map_variables(z, weather_tbl, tds_tbl): ''' Update tables with variables passed in from the map. Necessary because data was initially loaded before variables were chosen in the GIS-map part of the app. Over-writes table values when the model parameters page loads on the users screen. ''' map_dict = helpers.json_load(cfg.map_json) weather_file = map_dict.get('file_name') tds_value = map_dict.get('FeedC_r') #indexes were calculated earlier in the code if weather_file: weather_tbl[wf_index]['Value']=str(weather_file) if tds_value: tds_tbl[tds_index]['Value']=tds_value return (weather_tbl,tds_tbl)
