 Now that you've got a user in your database lets make sure we can find them again with SQL. Take the name entered above (in this case `richard`)  and search the database for it:
 
 
+    > User.first.name

     > User.where(:name => 'richard')

 Great that found ALL of the users named 'richard', if you got an empty array try again, make sure to use the name you used. If we wanted to find only one richard, we could limit the query and pull out the first user like this:

+    => 'richard'
     > User.where(:name => 'richard').first
     => #<User id: 1, name: "richard", ... >
 
 Cool, now we can store that user to a variable to use later:
