Public Class Methods
The list of columns names the model should ignore. Ignored columns won't have attribute accessors defined, and won't be referenced in SQL queries.

The name of the internal metadata table. By default, the value is "ar_internal_metadata"
.
# File activerecord/lib/active_record/model_schema.rb, line 79
Sets the name of the internal metadata table.
# File activerecord/lib/active_record/model_schema.rb, line 85
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"]
.
# File activerecord/lib/active_record/model_schema.rb, line 92
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"
.
# File activerecord/lib/active_record/model_schema.rb, line 67
Sets the name of the schema migrations table.
# File activerecord/lib/active_record/model_schema.rb, line 73
The prefix string to prepend to every table name.
# File activerecord/lib/active_record/model_schema.rb, line 31
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 activerecord/lib/active_record/model_schema.rb, line 44
The suffix string to append to every table name.
# File activerecord/lib/active_record/model_schema.rb, line 50
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.
