table_name() public

Guesses the table name (in forced lower-case) based on the name of the class in the inheritance hierarchy descending directly from ActiveRecord. So if the hierarchy looks like: Reply < Message < ActiveRecord, then Message is used to guess the table name from even when called on Reply. The rules used to do the guess are handled by the Inflector class in Active Support, which knows almost all common English inflections (report a bug if your inflection isn’t covered).

Additionally, the class-level table_name_prefix is prepended to the table_name and the table_name_suffix is appended. So if you have "myapp_" as a prefix, the table name guess for an Account class becomes "myapp_accounts".

You can also overwrite this class method to allow for unguessable links, such as a Mouse class with a link to a "mice" table. Example:

  class Mouse < ActiveRecord::Base
     set_table_name "mice"
  end

Examples of Setting the Prefix and Suffix

Both of the following will work for setting the prefix or suffix:

class Mouse < ActiveRecord::Base
  self.table_name_prefix = 'forum_'
end

and

class Mouse < ActiveRecord::Base
  def self.table_name_prefix
    'forum_'
  end
end
