Generic cheat-sheet¶

This section presents common questions along with some relevant examples.

eQual Apps¶

Console¶

http://equal.local/console.php

Workbench¶

http://equal.local/workbench

CLI commands¶

Should be located at the root of eQual (folder containing file run.php)

Grant DB rights¶

Available rights:

create
read
update
delete
manage

You can grant one right for one entity at a time:

./equal.run --do=group_grant --group=default --right=update --entity="core\User"

Test package consistency¶

This controller runs some consistency checks and works with any package:

PATH	`core\actions\test\package-consistency.php`
URL	`?do=test_package-consistency&package=core`
CLI	`$ ./equal.run --do=test_package-consistency --package=core --level=warn`
DESCRIPTION	Consistency checks between DB and class as well as syntax validation for classes (PHP), views and translation files (JSON).

The level property has 3 options :

'error' ( ex: missing property 'entity' in file: "packages\/lodging\/views\/sale\booking\InvoiceLine.form.default.json")

'warn' ( ex: WARN - I18 - Unknown field 'object_class' referenced in file "packages\/core\/i18n\/en\/alert\MessageModel.json"

* (error & warn).

Initiate eQual core in DB¶

PATH	`core\actions\init\package.php`
URL	`?do=init_package&package=core`
CLI	`$ ./equal.run --do=init_package --package=core`
DESCRIPTION	Initialise database for given package. If no package is given, initialize core package.

(this step is mandatory for every new installation)

Initiate your package in DB¶

PATH	`core\actions\init\package.php`
URL	`?do=init_package&package=myPackage`
CLI	`$ ./equal.run --do=init_package --package=myPackage`
DESCRIPTION	Initialise database for given package. If no package is given, initialize core package.

Initiate your package with initial data in DB¶

PATH	`core\actions\init\package.php`
URL	`?do=init_package&package=myPackage&import=true`
CLI	`$ ./equal.run --do=init_package --package=myPackage --import=true`
DESCRIPTION	Initialise database for given package. If no package is given, initialize core package.

Seed data for your package¶

PATH	`core\actions\init\seed.php`
URL	`?do=init_seed&package=myPackage`
CLI	`$ ./equal.run --do=init_package --package=myPackage`
DESCRIPTION	Seed objects for package using json configuration files in "{package}/init/seed/".

Run package test unit¶

PATH	`core\actions\test\package.php`
URL	`?do=test_package&package=core`
CLI	`$ ./equal.run --do=test_package --package=core`
DESCRIPTION	The controller checks the presence of test units for a given package and runs them, if any. (page :'Testing').

Invoking Controllers¶

Data provider¶

PATH	`/packages/mypackage/data/my-controller.php`
URL	`?get=mypackage_my-controller`
CLI	`$ ./equal.run --get=model_collect --entity="mypackage\MyClass"`
PHP	`run('get', 'mypackage_MyClass')`

Collect is the name of the controller, and model the directory to which it belongs.

Action handler¶

PATH	`/packages/mypackage/actions/subdir/my-action.php`
URL	`?do=mypackage_subdir_my-action`
CLI	`$ ./equal.run --do=model_update --entity=mypackage\MyObject --fields=[ids]=1 --fields=[name]=example`
PHP	`run('do', 'mypackage_myobject_action', [/* parameters */])`

Howtos¶

How to create a new object?¶

<?php
use core\User;

User::create(['firstname'=>'Bart']);
// which is equivalent to
User::create()->update(['firstname'=>'Bart']);

Note: When creating an object, by default, the state fields is assigned to 'instance', unless another value is given as parameter (ex. state=draft)

How to check if a given object does exist?¶

<?php
// count the number of items returned by the search method
if(count(search($object_class, array(array(array('id', '=', $object_id)))))) {...}

How to browse all objects of a given class?¶

<?php
// note: ensure the specified class does actually exist
$res = browse($object_class, search($object_class));

How to add a clause to every condition?¶

<?php
// example: add the (deleted = 1) clause to every condition
for($i = 0, $j = count($domain); $i < $j; ++$i)
    $domain[$i] = array_merge($domain[$i], array(array('deleted', '=', '1')));

How to obtain output (json/html) from another script ?¶

<?php
// There are 2 possibilities :

// either use a HTTP request
load_class('utils/HttpRequest');
$request = new HttpRequest(FClib::get_url(true, false).
'?get=core_objects_list&object_class=School%5CTeacher&rp=20&page=1&sortname
=id&sortorder=asc&domain%5B0%5D%5B0%5D%5B%5D=courses_ids&domain%5B0%5D%5B
0%5D%5B%5D=contains&domain%5B0%5D%5B0%5D%5B2%5D%5B%5D=1&fields%5B%5D=id&
fields%5B%5D=firstname&fields%5B%5D=lastname');
$json_data = $request->get();

// or use PHP output buffering (to prevent scope collision, remember to 
// embed such code into a function)
function get_include_contents($filename) {
    ob_start(); 
    include($filename); // assuming  parameters required by the script 
    // being called are present in the current URL 
    return ob_get_clean();
}
$result = get_include_contents('packages/core/data/objects/list.php');

How to sort the result of the browse method (without calling search method)?¶

<?php
// $order is an array containing fields names on which we want the result 
// set sorted 
// $result is an array returned by a call to the browse method

foreach($order as $ofield) {
    uasort($result, function ($a, $b) use($ofield){
        if ($a[$ofield] == $b[$ofield]) return 0;
        return ($a[$ofield] < $b[$ofield]) ? -1 : 1;
    });
}

How to request fields from all sub-objects at once?¶

<?php
$pages_values = $orm->read('icway\Page', $pages_ids, array('url_resolver_id'), 
$lang);         
$url_ids = array_map(function($a){return $a['url_resolver_id'];}, $pages_values);
$url_values = $orm->read('core\UrlResolver', $url_ids, ['human_readable_url']);
