Making reference to the tutorial: https://dash.plot.ly/urls
With the following code for index.py
, when the below is run, there is no pathname
for dcc.Location
, and the code always yields 404.
How is it intended to work?
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output
from app import app
from apps import app1, app2
app.layout = html.Div([
dcc.Location(id='url', refresh=False),
html.Div(id='page-content')
])
@app.callback(Output('page-content', 'children'),
[Input('url', 'pathname')])
def display_page(pathname):
if pathname == '/apps/app1':
return app1.layout
elif pathname == '/apps/app2':
return app2.layout
else:
return '404'
if __name__ == '__main__':
app.run_server(debug=True)```
