Question

I’m trying to select the User Id as a variable in the console however I keep ending up with:

 [#<User id: 4>]

The find statement I have tried is:

 userid = User.select('id').where('username = ?', 'uwZgf')

I’ve also tried with find_by_sql with same result.

What do I need to get the value out instead of the hash?

Answer 1

What you’ve got there is an array of one User object.

User.select(...).where(...).first.id

Would do the trick (you’d probably want to check the value returned by first before trying to call id on it.

You might find

User.find_by_username('foo').try(:id)

more readable.
