php - Nested collection fields in Sonata Admin (2.3) -
i'm having problems creating form creating course. part of database scheme i'm trying create form:
so i'm trying create course can create sessions , dates (moment) attached session. should this:
in courseadmin class have:
protected function configureformfields(formmapper $formmapper) { $formmapper ->add('name', 'text', array('label' => 'naam')) ->add('description', 'textarea', array('label' => 'beschrijving')) ->add('materials', 'textarea', array('label' => 'benodigde materialen')) ->add('numberofparticipants', 'number', array('label' => 'aantal deelnembers')) ->add('numberofdays', 'number', array('label' => 'aantal dagen')) ->add('price', 'number', array('label' => 'prijs')) ->add('pricekmo', 'number', array('label' => 'kmo-portefeuille prijs')) ->add('location', 'sonata_type_model', array('expanded' => true, 'by_reference' => false, 'multiple' => true, 'btn_add' => false)) ->add('session', 'sonata_type_collection', array( 'by_reference' => false, 'type_options' => array( // prevents "delete" option being displayed 'delete' => false, 'delete_options' => array( // may otherwise choose put field hide 'type' => 'hidden', // in case, need fill in options 'type_options' => array( 'mapped' => false, 'required' => false, ) ) ) ), array( 'edit' => 'inline', 'inline' => 'table', 'sortable' => 'position' )) ; } in sessionadmin class have:
protected function configureformfields(formmapper $formmapper) { $formmapper ->add('type', 'text', array('label' => 'type opleiding (dag / avond)')) ->add('moment', 'sonata_type_collection', array( 'by_reference' => false, 'type_options' => array( // prevents "delete" option being displayed 'delete' => false, 'delete_options' => array( // may otherwise choose put field hide 'type' => 'hidden', // in case, need fill in options 'type_options' => array( 'mapped' => false, 'required' => false, ) ) ) ), array( 'edit' => 'inline', 'inline' => 'table', 'sortable' => 'position' )) ; } and in momentadmin class have:
protected function configureformfields(formmapper $formmapper) { $formmapper ->add('time', 'date', array('label' => 'datum')) ; } the problem in form when try add moment (date) session following error:
fatalerrorexception: error: call member function getname() on null in /myproject/app/cache/dev/classes.php line 9772
so, can add session when try add moment session i'm getting error ... .
when in file classes.php on rule 9771 , 9772 there is:
$childformbuilder = $this->getchildformbuilder($formbuilder, $elementid); $fielddescription = $admin->getformfielddescription($childformbuilder->getname()); the $childformbuilder null.
when @ function this:
public function getchildformbuilder(formbuilder $formbuilder, $elementid) { foreach (new formbuilderiterator($formbuilder) $name => $formbuilder) { if ($name == $elementid) { return $formbuilder; } } return; } when var_dump of $name , $elementid this:
public function getchildformbuilder(formbuilder $formbuilder, $elementid) { foreach (new formbuilderiterator($formbuilder) $name => $formbuilder) { var_dump("name: " . $name); var_dump("elementid: " . $elementid); if ($name == $elementid) { return $formbuilder; } } die; return; } and push on add new button following picture:
then output:
name: s56cda71d2daa0_name elementid: s56cda71d2daa0_session_0_moment name: s56cda71d2daa0_description elementid: s56cda71d2daa0_session_0_moment name: s56cda71d2daa0_materials elementid: s56cda71d2daa0_session_0_moment name: s56cda71d2daa0_numberofparticipants elementid: s56cda71d2daa0_session_0_moment name: s56cda71d2daa0_numberofdays elementid: s56cda71d2daa0_session_0_moment name: s56cda71d2daa0_price elementid: s56cda71d2daa0_session_0_moment name: s56cda71d2daa0_pricekmo elementid: s56cda71d2daa0_session_0_moment name: s56cda71d2daa0_location elementid: s56cda71d2daa0_session_0_moment name: s56cda71d2daa0_session elementid: s56cda71d2daa0_session_0_moment in entities have __tostring function. example in course entity:
public function __tostring() { if(!is_null($this->name)) { return $this->name; } else{ return ""; } } what problem here? i'm stuck this. i've posted issue on github repo of sonata admin no answers ...

i've changed require in composer.json "sonata-project/admin-bundle": "^2.4@dev" , updated composer. i'm getting error:
contexterrorexception: warning: illegal string offset 'admin' in app/cache/dev/classes.php line 10482
the error in function:
public function getdashboardgroups() { $groups = $this->admingroups; foreach ($this->admingroups $name => $admingroup) { if (isset($admingroup['items'])) { foreach ($admingroup['items'] $key => $item) { if (''!= $item['admin']) { $admin = $this->getinstance($item['admin']); if ($admin->showin(admin::context_dashboard)) { $groups[$name]['items'][$key] = $admin; } else { unset($groups[$name]['items'][$key]); } } else { unset($groups[$name]['items'][$key]); } } } if (empty($groups[$name]['items'])) { unset($groups[$name]); } } return $groups; } the errors in on line : if (''!= $item['admin']) { .
in config.yml have:
sonata_admin: title: studyx title_logo: bundles/studyxenrolment/images/logo.png templates: layout: studyxenrolmentbundle:admin:standard_layout.html.twig edit: studyxenrolmentbundle:crud:edit.html.twig user_block: studyxenrolmentbundle:admin:user_block.html.twig # search: sonataadminbundle:core:search.html.twig # search_result_block: sonataadminbundle:block:block_search_result.html.twig dashboard: groups: studyx.admin.group.inschrijvingen: label: inschrijvingen items: ~ item_adds: - sonata.admin.enrolment studyx.admin.group.algemeen: label: algemeen items: ~ item_adds: - sonata.admin.course - sonata.admin.student studyx.admin.group.extra: label: items: ~ item_adds: - sonata.admin.location blocks: - position: top class: col-md-12 type: sonata.admin.block.admin_list so think function getdashboardgroups called there.
update 3:
in composer.json have following:
"sonata-project/block-bundle": "~2.3", "sonata-project/admin-bundle": "^2.4@dev", "sonata-project/doctrine-orm-admin-bundle": "2.3.*", "sonata-project/formatter-bundle": "^2.3" should update them ^2.4@dev ?
this error occurs because have more 2 level of nested collection forms, , it's not yet supported in release of sonata-admin.
from @rande (owner) , sonata maintainers @ issues #262, #1228, #1327 , #1971 :
this still not supported ....
you can @ old pr #1971 should solve problem use cases only.
the solution propose implement fix provided last opened pr #2985.
because pr not merged, need tell composer load rather current (not-working expected) version. (see composer , vcs).
hope pr merged soon.
until is, feel free fix problem @ moment using directly, several people do.
update
the pull request #3553 has been merged , fix problem of nested collections @ > 2 levels (nested in nested).
to fixed release, must use dev-master tag of bundle (at least commit 926f159 representing merge of pr).
i tried , works following requirement:
// composer.json "require": { "sonata-project/admin-bundle": "^2.4@dev", ... }, i hope can upgrade bundle in order fix.
update2
apparently, composer doesn't take last changes of branch.
fix provided pr #2739 has been merged 6 days ago.
to fix last 1 (hope), need change short code block in adddepencycallscompilerpass located in vendor/sonata-project/admin-bundle/dependencyinjection/compiler/adddependencycallscompilerpass.
at line 95, replace line :
$groupdefaults[$resolvedgroupname]['items'][] = $id; to ones:
$groupdefaults[$resolvedgroupname]['items'][] = array( 'admin' => $id, 'label' => !empty($attributes['label']) ? $attributes['label'] : '', 'route' => '', 'route_params' => array(), ); like it's done pr (it's needed change make working).
i make fix manually because it's new, , after days/weeks, run following commands:
composer clear-cache , composer update sonata-project/admin-bundle
you should try before adding fix manually, maybe changes added.
also, can use link composer , vcs given @ begin of answer , require fix directly. it's @ own appreciation because of it's solution @ moment.
and last, patient, fixes merged in stable releases soon.
