The name of the internal metadata table. By default, the value is
"ar_internal_metadata".
Sets the name of the internal metadata table.
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.

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.

The array of names of environments where destructive actions should be
prohibited. By default, the value is ["production"].
Sets an array of names of environments where destructive actions should be prohibited.
The name of the schema migrations table. By default, the value is
"schema_migrations".
Sets the name of the schema migrations table.
The prefix string to prepend to every table name.
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.
The suffix string to append to every table name.
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.
