mysql - Foreign key relationship methods deferred and never created in RDBO -

-

i'm playing rosedb::object on employees test dataset, , reason, can't foreign key relationships ('department' , 'employee') work on deptemp object. (class structure below).

when try $e->dept_emp->[0]->department, get:

can't locate object method "department" via package "my::fakeemployees::deptemp"  methods following relationships , foreign keys deferred , never created in class my::fakeemployees::deptemp.  type            name ----            ---- foreign key     department foreign key     employee

i'm sure have set wrong in class structure, what?

class structure (some classes omitted clarity):

i created various objects using instructions in rdbo tutorial:

package my::fakeemployees::employee;  use strict;  use base qw(my::fakeemployees::db::object);  __package__->meta->setup(     table => 'employees',      columns => [         emp_no     => { type => 'serial',  not_null => 1 },         birth_date => { type => 'date',    not_null => 1 },         first_name => { type => 'varchar', length   => 14, not_null => 1 },         last_name  => { type => 'varchar', length   => 16, not_null => 1 },         gender     => { type => 'enum',    check_in => [ 'm', 'f' ], not_null => 1 },         hire_date  => { type => 'date',    not_null => 1 },     ],      primary_key_columns => ['emp_no'],     'relationships'     => [         'departments' => {             'type'      => 'many many',             'map_class' => 'my::fakeemployees::deptemp',         },         'dept_emp' => {             'type' => 'one many',             'class' => 'my::fakeemployees::deptemp',             'column_map' => { 'emp_no' => 'emp_no' },         },         'dept_manager' => {             'type' => 'one many',             'class' => 'my::fakeemployees::deptmanager',             'column_map' => { 'emp_no' => 'emp_no' },         },         'salaries' => {             'type' => 'one many',             'class' => 'my::fakeemployees::salary',             'column_map' => { 'emp_no' => 'emp_no' },         },         'titles' => {             'type' => 'one many',             'class' => 'my::fakeemployees::title',             'column_map' => { 'emp_no' => 'emp_no' },         },     ], );  __package__->meta->make_manager_class('employees');  1;  package my::fakeemployees::deptemp;  use strict;  use base qw(my::fakeemployees::db::object);  __package__->meta->setup(     table => 'dept_emp',      columns => [         dept_no   => { type => 'character', not_null => 1 },         emp_no    => { type => 'integer',   not_null => 1 },         from_date => { type => 'date' },         to_date   => { type => 'date' },     ],      primary_key_columns => [ 'emp_no', 'dept_no' ],      foreign_keys => [         department => {             class       => 'my::fakeemployees::departments',             key_columns => { dept_no => 'dept_no' },         },          employee => {             class       => 'my::fakeemployees::employees',             key_columns => { emp_no => 'emp_no' },         },     ], ); __package__->meta->make_manager_class('dept_emp');   1;  package my::fakeemployees::department;  use strict;  use base qw(my::fakeemployees::db::object);  __package__->meta->setup(     table => 'departments',      columns => [         dept_no   => { type => 'character', length => 4,  not_null => 1 },         dept_name => { type => 'varchar',   length => 40, not_null => 1 },     ],      primary_key_columns => ['dept_no'],      unique_key => ['dept_name'],      'relationships'     => [         'employees' => {             'type'      => 'many many',             'map_class' => 'my::fakeemployees::deptemp',         },     ], ); __package__->meta->make_manager_class('departments');  1;

your foreign key has typo:

foreign_keys => [     department => {         class       => 'my::fakeemployees::departments',

that should 'department', not 'departments'

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
