table add_row error

[figoyouwei]

Hi,

I added an add_row method in this .py https://github.com/figoyouwei/taipy_success/blob/main/apps/yfin/pages/yfin.py

The GUI shows the add button, but when clicked on, it returns: WARNING:root: --- 1 warning(s) were found for page 'yfinance' in variable 'gui_core_sc_error' ---

• Warning 1: table.on_add: add_row is not a function.

taipy_success/.venv/lib/python3.12/site-packages/taipy/gui/gui.py:1392: TaipyGuiWarning: on_action(): 'add_row' is not a valid function. _warn(f"on_action(): '{action}' is not a valid function.")

[FlorianJacta]

This means there is an issue with your function. Can you add debug=True in your run?

<Your Gui>.run(..., debug=True)

This way, the error message will show you more information. Then, you can send me the error message and we will look at it together!

[figoyouwei]

Yes, debug=True in the code, and that was all the message I got. Please run the code and fix it?

[FlorianJacta]

Please add more details to your issue. I don't know what code I should run. This code cannot be run by itself: https://github.com/figoyouwei/taipy_success/blob/main/apps/yfin/pages/yfin.py

Where do you use it? Where do you start your Gui with this page? What steps do you take to have this issue? Do you have any other logs associated?

[figoyouwei]

It is under the app called yfin https://github.com/figoyouwei/taipy_success/blob/main/apps/yfin

And there is the main.py to run the GUI and you will see this table.

[FlorianJacta]

You are creating defining your page in the script where add_row is and add_row is also not imported in your main.py.

I would suggest keeping the normal way of creating the pages. yfin.py

ok, I think I see your point with the "you could or should define it in yfin.py".

The code is ok with add_row, I will play around with the edit and delete and comment back.

[FlorianJacta]

Great!

[figoyouwei]

edit and delete both work.

[FlorianJacta]

Great news!
