Hi everyone,
For a customer loyalty app, I want to record, in some column of the user’s profile, the amount of money the user spends at a coffee shop.
So when the user buys something, they can add the ticket/invoice with the value spent. And I want to add that spent value to a column on his profile.
But I see that there is no “append” function to a column.
I understand that when uploading the invoice, I can bring the value spent from your profile up to that moment, but how do I set the new value to the profile? Why I can’t set A+B either?
Being “A” the current value of the profile and “B” the value of the ticket.
Thanks for any help!
