user instance is not valid

[the1mills]

Followed the instructions in the readme, got this error:

/Users/t_millal/WebstormProjects/crucible-poc/server/boot/script.js:29
      throw err;
      ^
ValidationError: The `user` instance is not valid. Details: `email` is invalid (value: "john@doe.com"); `username` is invalid (value: "John").,ValidationError: The `user` instance is not valid. Details: `email` is invalid (value: "jane@doe.com"); `username` is invalid (value: "Jane").,ValidationError: The `user` instance is not valid. Details: `email` is invalid (value: "bob@projects.com"); `username` is invalid (value: "Bob").

anyone know what might cause this? thanks

I fixed this problem - what was happening is that the automigration was not complete before creating the db entities.

For your use, the following is the same script in the readme, but blocks on automigration:

the above assumes you are using postgres (psql)

this line above

app.dataSources.psql.automigrate(item, function (err) {})

will differ for whoever you are

(you can close issue, thx)

@ORESoftware - This reply saved me a massive headache! Thanks!

[the1mills]

Np! This automigration stuff is massively useful for working with standard RDBMs. (I am ORESoftware's alter ego :)
