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

Obtain the values of the parameters of the url, by means of the parameter data of the function.

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}", title="Flet-Easy")
def home_page(data: fs.Datasy, id, name):

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

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

Advanced Form

Use dynamic parameters in the url to contain specific data, for example id is requested to be a number and name 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}", title="Flet-Easy")
def home_page(data: fs.Datasy, id:int, name:str):

    return ft.View(
        controls=[
            ft.Text(f"ID: {id} \nNAME: {name}", size=50),
        ],
        vertical_alignment=ft.MainAxisAlignment.CENTER,
        horizontal_alignment=ft.CrossAxisAlignment.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}",
    title="Flet-Easy",
    custom_params={"Uuid": is_uuid},
)
def home_page(data: fs.Datasy, id: int, name: str, uuid: UUID):
    return ft.View(
        controls=[
            ft.Text(f"ID: {id} \nNAME: {name}\nUUID: {uuid}", size=50),
        ],
        vertical_alignment=ft.MainAxisAlignment.CENTER,
        horizontal_alignment=ft.CrossAxisAlignment.CENTER,
    )

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