In Rails there is a set of naming conventions you need to use, in
order to make the development process of your Rails application
painless. Tables are plural nouns in snake case. Models are singular
nouns in camel case. These two conventions were made to enable Rails
to automatically detect the name of a table, based on the name of a
model.
RacingCar model => racing_cars table.
This kind of strict conventions does not exist for column names,
because Rails doesn't have to link them up to something else. Even
though, it's recommended to name your columns with snake case. If you
really, really want to get around this, you can go to the migration
file that the scaffold generator created for you and edit the table's
name manually and then, in your model, add this line:
set_table_name "Customers"
(But I hope you'll learn to accept the naming conventions of Rails,
soon.)
