Back to the beginning

Circular references are easy in Grimoire. Just add the option argument for an eariler page.

Warning: Be careful about creating infinite loops. Grimoire will continue rendering pages as long as it's seeing a version of the state that hasn't previously been rendered.

@app.page(start=True)
def start(state, second):
    state.message = "Hello, traveller"
    return Div(
        P("Hello, Grimoire!"),
        Ul(Li(link("Go to the second page", second)))
    ), state


@app.page()
def second(state, start):
    return Div(
        P(f"message: {state.message}"),
        Ul(Li(link("Start over", start)))
    ), state
