Is there a simple way to do this?
Or is this the only way to do it?
prices_to_show.update({id: i_question_type_P.value},{number_available: prices_to_show.data.where('id', i_question_type_P.value, '==')[0].number_available - 1})
Where are you calling this from? Is it from within a repeat region created by the data store data or is it just some random button on the page, not related to this?
Good question! It is on a dmx-on:updated on a <select> element.
So is this select in a repeat region created by the data store [data]? Or is it just randomly placed on the page?
It is in a repeat, but not a repeat of this specific data store, hence it is in a random place on the page!
Then that’s the way to update it.
Thanks!
