[MohamedElgamal]

Hello everyone , having the following scenario i have class called StateItem that contain a collection of widget and checkbox and the StateItem class is called in class called StateTabContent() that create more than one object of StateItem depend the data saved in database, the checkbox that life in StateItem object i want when i clicking on it send the data member of StateItem to database
this is my following code :

class StateItem(Static):
    def __init__(self, username, state, request):
        super().__init__()
        self.current_logged_user = username
        self.state = state
        self.request = request

    def compose(self) -> ComposeResult:
        yield Horizontal(
            Label(id="issue-type", renderable=self.request.get_type())
            , Label(id="issue-user", renderable=self.request.get_user())
            , Label(id="issue-details", renderable=self.request.get_request_details())
            , Label(id=f"issue-created-at-{self.request.get_id()}", renderable=str(self.request.get_created_at()))
            , Checkbox(classes="issue-checkbox")
            , classes="state-item"
            , id=f"horizontal-con-{self.request.get_id()}"
        )

    def on_mount(self):
        pass

    @on(Checkbox.Changed, ".issue-checkbox")
    def state_request_checkbox_clicked(self, event):
        is_completed = admin_dao.move_request_to_next_state(self.request.get_id, self.state.get_id())
        self.remove()


class StateTabContent(Widget):
    def __init__(self, username, state):
        super().__init__()
        self.current_logged_user = username
        self.state: StateModel = state

    def compose(self) -> ComposeResult:
        requests_state_records = admin_dao.get_requests_records(self.state.get_id())
        with VerticalScroll():
            for request in requests_state_records:
                yield StateItem(self.current_logged_user, self.state, request)

and screen output

the following is happen to me when i click on checkbox nothing happen only the widget is removed ,i know the problem is coming from it can't access the data member of StateItem object but i don't know how to fix it

I'm struggling to follow the question, or quite see how it relates to the title of the discussion, but to answer the question in the title: a widget's parent is available by its parent property.

As for the main body of the question above, do you think you could try and make a small stand-alone example of what it is you want to do and explain what's not working?

what i want when the checkbox is clicked to access the member attribute of the class who composed the checkbox to sent it to database
sample code of what i tried to achieve

class StateItem(Static):
    def __init__(self, value):
        super().__init__()
        self.saved_value = value

    def compose(self) -> ComposeResult:
        yield Horizontal(
            Label(id="issue-type", renderable=self.request.get_type())
            , Checkbox(classes="issue-checkbox")
            , id="horizontal-con"
        )

    def on_mount(self):
        pass

    @on(Checkbox.Changed, ".issue-checkbox")
    def state_request_checkbox_clicked(self, event):
        // i want to get the saved_value attribute of StateItem here
        database.sendvalue(self.saved_value)
        self.remove()

[davep]

I'm afraid that doesn't really clarify the question. In that example code state_request_checkbox_clicked is a method of StateItem, so self.saved_value would be the saved_value attribute of the widget that composed the Checkbox.

[MohamedElgamal]

when i tried self.saved_value the returned value is None so i think the self keyword in state_request_checkbox_clicked is relate to checkbox class not StateIten

[davep]

Given the code you've shown above, saved_value is a property of on instance of StateItem. If you are accessing it and the value is None that means it does exist as a property of an instance of StateItem, but that its value is None. Textual's Checkbox doesn't have a property called saved_value. If you were somehow attempting to access saved_item on an instance of a Checkbox that would be an AttributeError.

i figured out the problem i forget brackets
at this line :
is_completed = admin_dao.move_request_to_next_state(self.request.get_id, self.state.get_id())
sorry bro i have another question if you don't mind
I have three tabs in my application, namely "Ready," "In Progress," and "Completed," the content of each tab is fetched from the database. I want to ensure that when a tab is clicked, the data is fetched again because it might have been changed or updated.

Just to confirm, this question above was posted in a new discussion #3201 (which made sense as on a different topic) and answered by davep within the hour. Of course nothing wrong with instead asking for help on Discord!

[davep]

Yup, as Tom says, here is just as good and as monitored as Discord.
