[Question] Deploy initial data from CSV file on a field with @readonly annotation

[ktesnim]

Hi CAP community,

I am trying to update our CDS model by using @readonly annotation for one of our fields.

Based on provided documentation Declarative Constraints | capire , I've understood that this will permit to ignore the field value on both Create and Update operation.

My question here is: will this impact deploying initial data for that field for that field using CSV file ? should I expect a regeneration of this table artifact with a different column definition when using @readonly annotation?

BR,

Tesnim

It's very easy to try this out yourself.

First:

cds init --add tiny-sample q && cd $_
echo "using CatalogService from './cat-service'; annotate CatalogService.Books : author with @readonly;" > srv/annotations.cds

Then:

cds deploy --to sqlite
sqlite3 db.sqlite 'select * from CatalogService_Books;'

which shows:

1|Wuthering Heights|Emily Brontë
2|Jane Eyre|Charlotte Brontë
3|The Raven|Edgar Allen Poe
4|Eleonora|Edgar Allen Poe
5|Catweazle|Richard Carpenter

Thus:

No impact on initial data deployment.
