internal_metadata_table_name
The name of the internal metadata table. By default, the value is "ar_internal_metadata".
internal_metadata_table_name=(table_name)
Sets the name of the internal metadata table.
pluralize_table_names
Indicates whether table names should be the pluralized versions of the corresponding class names. If true, the default table name for a Product class will be “products”. If false, it would just be “product”. See table_name for the full rules on table/class naming. This is true, by default.
pluralize_table_names=(value)
Set whether table names should be the pluralized versions of the corresponding class names. If true, the default table name for a Product class will be “products”. If false, it would just be “product”. See table_name for the full rules on table/class naming. This is true, by default.

endprimary_key_prefix_type
The prefix type that will be prepended to every primary key column name. The options are :table_name and :table_name_with_underscore. If the first is specified, the Product class will look for “productid” instead of “id” as the primary column. If the latter is specified, the Product class will look for “product_id” instead of “id”. Remember that this is a global setting for all Active Records.
primary_key_prefix_type=(prefix_type)
Sets the prefix type that will be prepended to every primary key column name. The options are :table_name and :table_name_with_underscore. If the first is specified, the Product class will look for “productid” instead of “id” as the primary column. If the latter is specified, the Product class will look for “product_id” instead of “id”. Remember that this is a global setting for all Active Records.
schema_migrations_table_name
The name of the schema migrations table. By default, the value is "schema_migrations".
schema_migrations_table_name=(table_name)
Sets the name of the schema migrations table.
table_name_prefix=(prefix)
Sets the prefix string to prepend to every table name. So if set to “basecamp_”, all table names will be named like “basecamp_projects”, “basecamp_people”, etc. This is a convenient way of creating a namespace for tables in a shared database. By default, the prefix is the empty string.
If you are organising your models within modules you can add a prefix to the models within a namespace by defining a singleton method in the parent module called table_name_prefix which returns your chosen prefix.
table_name_suffix=(suffix)
Works like table_name_prefix=, but appends instead of prepends (set to “_basecamp” gives “projects_basecamp”, “people_basecamp”). By default, the suffix is the empty string.
If you are organising your models within modules, you can add a suffix to the models within a namespace by defining a singleton method in the parent module called table_name_suffix which returns your chosen suffix.
