DBIx::Class::PK \- Primary Key class
.SH "SYNOPSIS"

.IX Header "DESCRIPTION"
This class contains methods for handling primary keys and methods
depending on them.
.SH "METHODS"
.IX Header "METHODS"
.SS "id"
.IX Subsection "id"
Returns the primary key(s) for a row. Can't be called as
a class method.
.SS "\s-1ID\s0"
.IX Subsection "ID"
Returns a unique id string identifying a row object by primary key.
Used by DBIx::Class::CDBICompat::LiveObjectIndex and
DBIx::Class::ObjectCache.
.IP "\s-1WARNING\s0" 4
.IX Item "WARNING"
The default \f(CW\*(C`_create_ID\*(C'\fR method used by this function orders the returned
values by the alphabetical order of the primary column names, \fBunlike\fR
the \*(L"id\*(R" method, which follows the same order in which columns were fed
to \*(L"set_primary_key\*(R" in DBIx::Class::ResultSource.
.SS "ident_condition"

.Vb 1
\&  my $cond = $result_source\->ident_condition();

.Ve
.PP
Produces a condition hash to locate a row based on the primary key(s).
