⚠️ repo was integrated into atk4/data ⚠️
This extension for Agile Data implements advanced reporting capabilities:
- Aggregate models. Provide grouping of existing model.
- Union models. Combine one or multiple models.
IMPORTANT - This repository is discontinued and functionality of Aggregate and Union models will be moved to https://github.com/atk4/data starting from version 2.3.0
This repository is now public and available under MIT license, so to install:
composer require atk4/reportYou may need to adjust your minimum-stability setting.
Create a new model that combines data from scopes of several nested models. Will help you map fields properly so that resulting model have the columns you want. In next example you would need to define Purchase and Sale models yourself. See https://github.com/atk4/data):
$m = new \atk4\report\UnionModel($db);
$m->addNestedModel(new Purchase(), [
'ref_no' => '[ref_no]', // mapping fields is optional
'date' => '[purchase_date]', // you can alias like this
'contact' => 'concat("From: ", [contractor_from])',
]); // use expressions
$m->addNestedModel(new Sale(), [
'date' => '[sale_date]', // this way we have one column for dates
'contact' => 'concat("To: ", [contractor_to])',
]);
$m->setOrder(['date']); // sorts resulting union model
$m->addField('date', ['caption' => 'Date', 'type' => 'date']);
// now add union-based models here.
$m->addField('contact', ['caption' => 'Supplier/Payee']);
$m->addField('ref_no', ['caption' => 'Document No']);
$m->addField('amount', ['caption' => 'Net Amount', 'type' => 'money']);
// if association in nested model is not explicitly defined, will
// use field. If no field is found, will use expression: "null"
$m->join('country', 'country_id')
->addField('country', 'name');
// Union Model extends \atk4\data\Model so you can use addField and addExpression
// $m->groupBy('country', ['amount'=>'sum([]')])
// groupBy works like in GroupModel, next example for usage.
$table->setModel($m);Creates a new model containing aggregate data from your existing model. Note that you can combine UnionModel and GroupModel recursively.
$m = new \smbo\GroupModel(new Sale($db));
$m->groupBy(['contractor_to', 'type'], [ // groups by 2 columns
'c' => 'count(*)', // defines aggregate formulas for fields
'qty' => 'sum([])', // [] refers back to qty
'total' => 'sum([amount])', // can specify any field here
]);
$m->addFields(['vat_registered', ['vat_no', 'caption' => 'VAT No']]);
// add 2 more fields which will bypass aggregation.
$m->getElement('total')->type = 'money';
// change the typehttps://github.com/atk4/report/blob/develop/docs/index.md
Implementation is complete, but a better documentation and more examples needed. Also some cleanups in the code are welcome!
