Hi @sylvoslee

Converting from a the dash-labs pages plug-in to the pages feature in dash 2.5 requires 3 steps:

remove import dash_labs as dl or upgrade dash-labs to V1.1.0 There is a conflict between dash-labs versions less than 1.1.0 when running a pages app in dash 2.5
change: app = Dash(__name__, plugins=[dl.plugins.pages]) to: app = Dash(__name__, use_pages=True)
change: dl.plugins.page_container to: dash.page_container

Let me know how it goes! The new dash docs with the pages feature will be ready soon.

I tried your demo（multi_page_basics）on dash2.5 and can't access http://127.0.0.1:8050/dashboard

Hi @sylvoslee. Thanks for reporting. There is an issue with pages in dash 2.5 for for anyone on Windows. There is a pull request to fix this - patch is coming soon.

sylvoslee commented 2 years ago

another question, how to get the hash value of the url

AnnMarieW commented 2 years ago

You can use the hash prop of dcc.Location

sylvoslee commented 2 years ago

Why can't pass hash value to layout function like query?

def layout(day=days[0], **other_unknown_query_strings):
    return html.Div(
        [
            dcc.Dropdown(
                id="dropdown",
                options=[{"label": x, "value": x} for x in days],
                value=day,
                clearable=False,
            ),
            dcc.Graph(id="bar-chart"),
        ]
    )
