Hello everyone,
Can I prevent a customer from using 1 address twice in my app.
I mean, that my client can only create the same address once in the database.
Thanks for the answers.
Yes this is possible. What is the use case and I will try to explain in those terms.
Thank you Rozza. I want to create a scalable subscription for my customers. For example, with the cheapest subscription he can use 20 photos, with the next subscription he can use 30 photos.
But the customer can work around it by using the same address twice so that he gets 20 photos each time. This could be prevented by preventing him from using the same address twice.
The same email address or same postal address?
Email: each email in the user table must be unique, Adalo won’t allow the same email address to be used twice.
Postal: have a collection of addresses_used with field location, . Then when they enter their new address via location input, only allow submission if the count of addresses_used = 0, with a filter addresses_used.location = current address.
Hi
Do you have a way you can validate the “address” (postal or email) & assign this uniquely to a single user?. If you dont then the best way is to validate mobile number. I have the same issue:
Postal Address cannot be verified & assigned to a particular user easily
Email can be validated but the user can register with multiple email addresses
Validating Mobile Number with an OTP is the best way as it is costly for a user to have many mobile numbers. The hurdle is that sending OTP to mobile numbers costs money. I have thus abandoned mobile otp and opted for Email validation. If a user creates many accounts then those are the breaks.
Thanks Razza and eduscvs. I try some off your ideas.
