Using the extensions means you can bypass Blob
and not need to call datatypeValue
directly. E.g.:
let uuid = Expression<Int>("uuid")
let png = Expression<UIImage?>("png")
if let insertedID = ingredientTable.insert(uuid <- createUUID() ,png <- pic) {
println("inserted id: \(insertedID)")
}
This also means that you'll get UIImage objects directly when accessing a retrieved row (no need to translate the Blob into a UIImage yourself):
for ingredient in ingredientTable {
let image = ingredient.get("png") // UIImage?
}
Beyond that, I've copied and pasted your code above and have had no issue compiling. Can you provide more code? I faked the missing data using the following:
let ingredientsTable = Database()["ingredients"]
func createUUID() -> Int { return 1 }
let pic = UIImage(named: "test")
from sqlite.swift.
Thanks for the clarification on the extension usage.
I did get my code above to compile when I changed png <- pic?.datatypeValue
to png <- pic!.datatypeValue
although I think that is not exactly what I want to be doing here.
I plan on updating my code to follow your extension instructions.
Thanks again. The project is a godsend.

What is png
exactly? In your example, it's:
Expression<Blob?>
But I'd expect the behavior you were getting above if it were:
Expression<Blob>
from sqlite.swift.
Is it safe to close this issue now?
from sqlite.swift.
Oh yes. It's working great now! Thanks again
