PRAGMA foreign keys = ON;

How can I activate foreign keys check before performing an Insert ? I’ve tried

knex.raw('PRAGMA foreign keys = ON;'); 

But it’s not working.

Any thoughts ?

Thanks !

So, the code there doesn’t actually do anything, as the db calls are async and it’s never executed with .exec or .then (or related promise methods). What you want to do is add an afterCreate on the pool and run one of the api’s for the sqlite3 as needed:

# Initialize knex library
knex = require('knex')(
  client : 'sqlite3'
  connection : 
    filename: "./db/scriptor.db"
  pool:
    afterCreate: (conn, cb) ->
       conn.run('PRAGMA foreign_keys = ON', cb);
)

That being said, I realized recently that the foreign_keys pragma being off by default in sqlite3 is a bit inconsistent. @vschoettke or @bendrucker, what do you think about changing this to be run by default (configurable to turn off in the config options) so foreign keys are consistent with the other databases.

+1 totally got me by surprise that SQLite has it off by default
