  • • Model class names such as EmailAccount are in CamelCase and are English singulars. 
     
    •  Database table names such as email_accounts use underscores between words and are English plurals. 
     
    •  Primary keys uniquely identify rows in relational databases. Active Record uses id for primary keys. 
     
    •  Foreign keys join database tables. Active Record uses foreign keys such as person_id with an English singular and an _id suffix.
  • When I took Rails out for a test drive, I freely admit my attitude was more than a little arrogant. I didn't think Active Record was up to the job, but I've since learned that it offers everything I need for some problems.
