i am using Postgrex library for my database, and i have the following problem: One of my column in the database is from type
uuid, i am using the UUID module in elixir but whenever i am trying to persist something on the databse i get the following error:
Postgrex expected a binary of 16 bytes, got "3c5fda26-ea3b-4c77-8f19-06e106a61eda", i have tried to store it as plain string but it was not possible as you can see, how should i convert the uuid before persisting it to the database?
UUID is a string, but not a "human readable string". What you see as
