clicking url is not responding in latest textual version

[vigne-Sh]

Context

• Added a table with set of formatted Links in a specific column using below syntax

[@click=link('https://www.google.com/{search_result}')]search[/]

• previously above action used to work when user clicks the url in both mac osx & linux, recently while updating the textual to 0.64.0 the urls are not clickable

The urls were responding properly in the below version

We did simplify actions recently. Previously it would check the app for an action if it wasn't found on the widget. Now you will need to be explicity.

Depending on where your action is defined, you can update it to app.link or screen.link

This is the rough structure of the App which was in working state, could you point out exactly where the action needs to be updated ?

The below example works in 0.47.1 & not 0.64.0

import webbrowser
from textual.app import App, ComposeResult
from textual.widgets import Header, Footer, DataTable
from rich.text import Text
from textual.screen import Screen



class DebugScreen(Screen):
    
    def compose(self):
        yield DataTable(id="test_table", name="debug_clicking")
    
    def on_mount(self):
        table = self.query_one(f"#test_table", DataTable)
        table.zebra_stripes = True
        table.cursor_type = "row"
        table.focus()
        table.add_columns(*("row", "link"))
        get_table_data(table)


class TestApp(App):
    SCREENS = {
        "input": DebugScreen,
    }

    BINDINGS = [("d", "toggle_dark", "Toggle dark mode")]

    def compose(self) -> ComposeResult:
        """Create child widgets for the app."""
        yield Header()
        yield Footer()

    def action_link (self, href: str) -> None:
        """
        action to invoke webbrowser when ever user
        clicks a href from rich markdown
        """
        webbrowser.open(href)

    
    def on_mount(self):
        self.push_screen("input")
        

    def action_toggle_dark(self) -> None:
        """An action to toggle dark mode."""
        self.dark = not self.dark


    
def get_table_data(table: DataTable):
    # makes api calls
    items = 10
    for i in range(items):
        table.add_row(
            f"Row-{i}",
            Text.from_markup(f"[deep_sky_blue1][@click=link('https://github.com/Textualize/textual/discussions/4641')]discussion[/][/deep_sky_blue1]")
        )
            

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

@click=link should be @click=app.link

Thanks @willmcgugan link -> app.link works, all the urls are responding without any issues
