Public Class Methods
The name of the column records are ordered by if no explicit order clause is used during an ordered finder call. If not set the primary key is used.
# File lib/active_record/model_schema.rb, line 111
Sets the column to sort records by when no explicit order clause is used during an ordered finder call. Useful when the primary key is not an auto-incrementing integer, for example when it's a UUID. Note that using a non-unique column can result in non-deterministic results.

The name of the internal metadata table. By default, the value is
"ar_internal_metadata"
.
# File lib/active_record/model_schema.rb, line 82
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 name of the schema migrations table. By default, the value is
"schema_migrations"
.
# File lib/active_record/model_schema.rb, line 70
Sets the name of the schema migrations table.

The prefix string to prepend to every table name.
# File lib/active_record/model_schema.rb, line 34
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.
# File lib/active_record/model_schema.rb, line 47
The suffix string to append to every table name.
# File lib/active_record/model_schema.rb, line 53
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.
