Let''s say I have a model called User. User has two attributes or table
columns: id, username
By using the code below I can check that there is a username "Tom" and
return 1 ifthere is and 0 if there is not
User.find_by_username("Tom")? 1 : 0
How would I find out Tom''s corresponding id?
For example I''m looking for something along the lines of:
User.find_by_username("Tom").id
