Dynamic routes

FletEasy provides a simple and powerful routing to manage the access to the pages created, it contains 3 ways of use (choose the one that suits you best).

Simple form

Get the values ​​of the URL parameters, using the data from the parameters of the function decorated by page().

Example

import flet as ft
import flet_easy as fs

app = fs.FletEasy(route_init="/test/10/user/dxs")

@app.page(route="/test/{id}/user/{name}")
def home_page(data: fs.Datasy, id, name):

    data.page.title = "Flet-Easy"

    return ft.View(
        controls=[
            ft.Text(f"ID: {id} \nNAME: {name}", size=50),
        ],
        vertical_alignment="center",
        horizontal_alignment="center",
    )

app.run(view=ft.AppView.WEB_BROWSER)

Advanced Form

Use dynamic parameters in the url to get specific data, for example {id:d} is requested to be a number and {name:l} a string. For more information here

Example

import flet as ft
import flet_easy as fs

app = fs.FletEasy(route_init="/test/10/user/dxs")

@app.page(route="/test/{id:d}/user/{name:l}")
def home_page(data: fs.Datasy, id:int, name:str):

    data.page.title = "Flet-Easy"

    return ft.View(
        controls=[
            ft.Text(f"ID: {id} \nNAME: {name}", size=50),
        ],
        vertical_alignment="center",
        horizontal_alignment="center",
    )

app.run(view=ft.AppView.WEB_BROWSER)

Custom validation

To control the validation of custom data in the dynamic path, you must use the custom_params parameter of the page decorator, in this you can enter the key and the value as a function, being a dictionary can support a wide variety of data, according to your imagination 🤔.

Example

from uuid import UUID
import flet as ft
import flet_easy as fs

app = fs.FletEasy(
    route_init="/test/10/user/dxs/a4cb5f2a-2281-4e66-85e4-441a40026357"
    )

def is_uuid(value):
    try:
        UUID(value)
        return value
    except ValueError:
        return False

@app.page(
    route="/test/{id:d}/user/{name:l}/{uuid:Uuid}",
    custom_params={"Uuid": is_uuid},
)
def home_page(data: fs.Datasy, id: int, name: str, uuid: UUID):
    data.page.title = "Flet-Easy"

    return ft.View(
        controls=[
            ft.Text(f"ID: {id} \nNAME: {name}\nUUID: {uuid}", size=50),
        ],
        vertical_alignment="center",
        horizontal_alignment="center",
    )

app.run(view=ft.AppView.WEB_BROWSER)
