Creating pages through methods fails

[AlexandreSajus]

This code which creates a page using a method:

from taipy import Gui
import taipy.gui.builder as tgb

def create_page():
    with tgb.Page() as page:
        tgb.html("p", "page")
    return page


class ProjectHub(Gui):
    def __init__(self):
        self.page_via_method = self.create_page()
        super().__init__(self.page_via_method)
        self.run(use_reloader=True, debug=True)

    def create_page(self):
        with tgb.Page() as page:
            tgb.html("p", "page")
        return page


if __name__ == "__main__":
    ProjectHub()

Fails with traceback:

@AlexandreSajus assign this to me

[jrobinAV]

@pravintargaryen It requires a deep understanding of Taipy code. We need to handle it internally. I remove the assignment.

I have not seen this syntax before. Can you let me know where you saw this one? Thanks!

[AlexandreSajus]

Which part of the syntax is unclear? Unfortunately, this is not my code. A Discord user reported this issue.

[dinhlongviolin1]

Gui object is not designed to be inherited. They can create an instance of the Gui instead of inheriting them.

[AlexandreSajus]

Okay I understand. We can close this as non-planned then

[FlorianJacta]

This does not work even if you don't inherit from the Gui. This code give the same error:

from taipy.gui import Gui
import taipy.gui.builder as tgb
import pandas as pd

class FoodDatabase:
    def __init__(self):
        self.food_df = pd.DataFrame({
            "Meal": ["Lunch", "Dinner", "Lunch", "Lunch"],
            "Category": ["Food", "Food", "Drink", "Food"],
            "Name": ["Burger", "Pizza", "Soda", "Salad"],
            "Calories": [300, 400, 150, 200],
        })

    def create_page(self):
        with tgb.Page() as page:
            tgb.table('{self.food_df}', filter=True)
            return page

if __name__ == '__main__':
    food_database = FoodDatabase()
    page = food_database.create_page()
    Gui(page).run(debug=True, use_reloader=True)

I don't think it is supposed to be supported in Taipy, but maybe it could be an improvement.
