Hi there, sorry if my question is confusing but Im facing this problem sometimes, probably obvious to fixI have one variable ( tokens ) inside a component who is set by a context variable ( screenshot )The context variable get all user infos, on this example Im using the context variable for get the current tokens amount of the userNow, I would like to refresh the variable of the child component each time the user click on a button inside the PARENT component ( which minus 1 the tokens amount to the user table ) , the parent and the child component don't share any attributes, how can I update the variable tokens inside the child component without using any attributes for the on attributes change event.Thanks

Hi there, sorry if my question is confusing but Im facing this problem sometimes, probably obvious to fix

I have one variable ( tokens ) inside a component who is set by a context variable ( screenshot )
The context variable get all user infos, on this example Im using the context variable for get the current tokens amount of the user
Now, I would like to refresh the variable of the child component each time the user click on a button inside the PARENT component ( which minus 1 the tokens amount to the user table ) , the parent and the child component don't share any attributes, how can I update the variable tokens inside the child component without using any attributes for the on attributes change event.

Thanks

this should be done as a formula
try the same thing as a formula and it will work 😊

Hi, but the child component will be not dynamically updated no ?

I mean the child
the very variable you here show us
the variable right here in the screenshot must be a formula
and then the value-change of the parent will immediately be tangible in that calculation

but, just an assumption, if you work with backend data (currentUser) – you should could also directly pull from the api into the formula for context
in general, there is no need to store it in a variable, unless you have some kind of local storage rule or similar things

create the formula directly into the parent then pass it into the child as attribute ?

I assume you want to add values together in this child
out of values
that you get from the parent's variable
in order to have it "immediately" you need to do the "add" as a formula, not as a variable
a variable needs a workflow in order to be refreshed
If you want we can do a quick call, its often more efficient and swift for both of us

the parent component and child not really share values, inside the parent component I minus the number of tokens from the DB ( user_record ) and the child show the updated number of tokens in realtime

at this moment the component need to be reload or I need to use an " useless " attribute for refresh dynamically the tokens values trought attribute on change event

because of this you need to do formulas instead of variables

yep, I set the formula inside the child component ( so as you said instead of create a variable I set a formula who get the values from the context variable )
but the child component dont get updated dynamically

I cant follow through your thoughts
we can do a quick call (costs you nothing) I could help you first hand
but maybe someone else here can hop in

I forget to mention but I show the current value of the tokens on a text html element, basically what I need is to just when the button is clicked on the parent component -> it's updated directly the value of on this txt element inside the child element ( throught the formula or the variable previously )
