Following the multi-page/multi-file example from the docs (https://dash.plot.ly/urls), I am getting this error trying to instantiate a dcc.Input
TypeError: __init__() takes exactly 1 argument (4 given)
I do not get this error when the same code is all in one file
Here is what I’m trying to do. Running “python index.py”, this error happens at the first dcc.Input in apps/app_1.py
app.py
import dash
app = dash.Dash()
index.py
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 app_1
app.layout = html.Div([
dcc.Location(id="url", refresh=False),
dcc.Link("App 1", href="/app-1"),
html.Div(id="page-content")
])
@app.callback(
Output("page-content", "children"),
[Input("url", "pathname")]
)
def display_page(pathname):
if pathname == "app-1":
return app_1.layout
if __name__ == "__main__":
app.run_server(debug=True)
apps/app_1.py
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output
from app import app
import datetime as dt
layout = html.Div([
html.H3("App 1"),
dcc.Input("begindate-input", type="Date", value=dt.date.today() - dt.timedelta(days=30)),
dcc.Input("enddate-input", type="Date", value=dt.date.today()),
])
