I have a serious problem with checkboxes. I’m creating a ToDo style application and I want it to save the changes (item_done = False or True) when the checkbox is clicked.

What I basically want is for there only to be the “This product has variations” checkbox, then if the user checks that box, then the Size and Colour checkboxes will show up. If the user clicks size, the size variation value box will show up. Same with colour. Right now although I am trying with my script to achieve this functionality, I can’t.

I’m trying to add a 24-hour time limit for each item added to a cart. I want the items removed from the cart after the time expires.

I have created a simple app to keep track of stock trades. I have a value for each trade “entry” called pnl, which calculates the profit or loss based on the position size, openeing price and closing price. This function is all done within the Entry model.
