Cannot assign value to Input widget on select changed

[Tim-Cao]

I would like to assign value to Input when trigger select changed event

from textual.app import App, ComposeResult, events
from textual.widgets import *


class ScriptApp(App):
    def compose(self) -> ComposeResult:
        PRODUCT_TEAM = [
            ("Business Platform Management", "bpm"),
        ]

        yield Label("Summary:", id="summary-label")
        yield Input(id="summary")
        yield Label("Product Team:", id="product-team-label")
        yield Select(PRODUCT_TEAM, id="product-team")

    def on_select_changed(self, event: Select.Changed) -> None:
        if event.select.id == "product-team":
            self.query_one("#summary").value == "Automate"


app = ScriptApp()

if __name__ == "__main__":
    app.run()

However, the value of summary is empty

Take a closer look at your code.

self.query_one("#summary").value == "Automate"

And if it doesn't leap out, this is why linters and type checks are very helpful...

Sorry, my mistake

Should be self.query_one("#summary").value = "Automate"
