Best practices for updating column type when there are existing records
I'm seeking some guidance on updating a column type when there are existing records in my database. Here's the scenario:
Original Model:
model User { id String @id @default(uuid()) posts String[]}
model User { id String @id @default(uuid()) posts String[]}
New Model:
model User { id String @id @default(uuid()) posts Int}
model User { id String @id @default(uuid()) posts Int}
As you can see, I'm transitioning the posts field from an array of strings to a single integer. However, I'm unsure about the best approach for handling this change when there is existing records with the
String[]
String[]
type.
If anyone has links, videos or documentation to share on this, would be greatly appreciated.
