我在创建用于创建类(class)的表单时遇到问题。这是我的数据库方案的一部分，我正在尝试为其创建一个表单:
所以我想做的是创建一个类(class)，我可以在其中创建 session 和附加到该 session 的日期(时刻)。它应该看起来像这样:
在我的CourseAdmin 类(class)中我有:
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 the "Delete" option from being displayed
'delete' => false,
'delete_options' => array(
// You may otherwise choose to put the field but hide it
'type' => 'hidden',
// In that case, you need to fill in the options as well
'type_options' => array(
'mapped' => false,
'required' => false,
)
)
)
), array(
'edit' => 'inline',
'inline' => 'table',
'sortable' => 'position'
))
;
}
在我的SessionAdmin 类中我有:
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 the "Delete" option from being displayed
'delete' => false,
'delete_options' => array(
// You may otherwise choose to put the field but hide it
'type' => 'hidden',
// In that case, you need to fill in the options as well
'type_options' => array(
'mapped' => false,
'required' => false,
)
)
)
), array(
'edit' => 'inline',
'inline' => 'table',
'sortable' => 'position'
))
;
}
在我的 MomentAdmin 类(class)中，我有:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('time', 'date', array('label' => 'Datum'))
;
}
我的表单中的问题是当我尝试向我的 session 添加时刻(日期)时出现以下错误:
FatalErrorException: Error: Call to a member function getName() on null in /myproject/app/cache/dev/classes.php line 9772
所以，我可以添加一个 session ，但是当我尝试向我的 session 添加一个时刻时，我收到了错误...。
当我在规则 9771 和 9772 中查看文件 classes.php 时，有:
$childFormBuilder = $this->getChildFormBuilder($formBuilder, $elementId);
$fieldDescription = $admin->getFormFieldDescription($childFormBuilder->getName());
$childFormBuilder 为 null。
当我查看该函数时，我得到了这个:
public function getChildFormBuilder(FormBuilder $formBuilder, $elementId)
{
foreach (new FormBuilderIterator($formBuilder) as $name => $formBuilder) {
if ($name == $elementId) {
return $formBuilder;
}
}
return;
}
当我像这样对 $name 和 $elementId 进行 var_dump 时:
public function getChildFormBuilder(FormBuilder $formBuilder, $elementId)
{
foreach (new FormBuilderIterator($formBuilder) as $name => $formBuilder) {
var_dump("name: " . $name);
var_dump("elementId: " . $elementId);
if ($name == $elementId) {
return $formBuilder;
}
}
die;
return;
}
然后按下添加新按钮，如下图所示:
然后我得到这个输出:
name: s56cda71d2daa0_name
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_description
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_materials
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_numberOfParticipants
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_numberOfDays
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_price
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_priceKmo
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_location
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_session
elementId: s56cda71d2daa0_session_0_moment
在我所有的实体中，我都有一个 __toString 函数。我的类(class)实体中的示例:
public function __toString()
{
if(!is_null($this->name))
{
return $this->name;
}
else{
return "";
}
}
这可能是什么问题？我真的坚持这个。我还在 Sonata Admin 的 github repo 上发布了一个 issue 但没有答案......

更新:
我在函数 getChildFormBuilder 中添加了一些 var_dump，如下所示:
public function getChildFormBuilder(FormBuilder $formBuilder, $elementId)
{
foreach (new FormBuilderIterator($formBuilder) as $name => $formBuilder) {
if ($name == $elementId) {
return $formBuilder;
}
}
var_dump(__METHOD__);
var_dump($elementId);
var_dump(debug_backtrace());
return;
}

更新 2:
我已将 composer.json 中的要求更改为 "sonata-project/admin-bundle": "^2.4@dev"并使用 composer 更新。但是现在我收到了这个错误:
ContextErrorException: Warning: Illegal string offset 'admin' in app/cache/dev/classes.php line 10482
错误在这个函数中:
public function getDashboardGroups()
{
$groups = $this->adminGroups;
foreach ($this->adminGroups as $name => $adminGroup) {
if (isset($adminGroup['items'])) {
foreach ($adminGroup['items'] as $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;
}
在线错误:if (''!= $item['admin']) { .
在我的 config.yml 我有:
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: Extra
items: ~
item_adds:
- sonata.admin.location
blocks:
-
position: top
class: col-md-12
type: sonata.admin.block.admin_list
所以我认为函数 getDashboardGroups 被调用了。
更新 3:
在我的 composer.json 中，我现在有以下内容:
"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"
我应该将它们全部更新为 ^2.4@dev 吗？
最佳答案
出现此错误是因为您有两个以上级别的嵌套集合表单，并且目前尚未在任何版本的 sonata-admin 中支持。
来自 @rande (所有者)和奏鸣曲维护者在问题 #262 , #1228 , #1327和 #1971 :
This is still not supported for now ....
你也可以看看这个老 PR #1971这应该只解决某些用例的问题。
我建议您的解决方案是实现上次打开的 PR #2985 提供的修复程序.
因为 PR 没有合并，您需要告诉 composer 加载它而不是当前(未按预期工作)版本。 (见 composer and VCS)。
希望 PR 尽快合并。
在此之前，请随时直接使用它来解决您的问题，就像几个人一样。
更新
Pull Request #3553最近被合并并修复了> 2层嵌套集合的问题(嵌套在嵌套中)。
要获得固定版本，您必须使用 bundle 的 dev-master 标记(至少来自 commit 926f159 表示 PR 的合并)。
我试过了，它可以很好地满足以下要求:
// composer.json
"require": {
"sonata-project/admin-bundle": "^2.4@dev",
...
},
我希望您可以轻松升级 bundle 以获得修复。
更新2
显然，您的 Composer 没有接受分支的最后更改。
PR 提供的修复 #2739已于 6 天前合并。
要修复最后一个(希望)，您需要更改位于 vendor/sonata-project/admin-bundle/DependencyInjection/Compiler/的 .AddDepencyCallsCompilerPass 中的一个非常短的代码块AddDependencyCallsCompilerPass
在第 95 行，替换这一行:
$groupDefaults[$resolvedGroupName]['items'][] = $id;
致那些人:
$groupDefaults[$resolvedGroupName]['items'][] = array(
'admin' => $id,
'label' => !empty($attributes['label']) ? $attributes['label'] : '',
'route' => '',
'route_params' => array(),
);
就像 PR 完成的一样(这是使其正常工作唯一需要的更改)。
我会手动进行修复，因为它很新，几天/几周后，运行以下命令:
composer clear-cache 和 composer update sonata-project/admin-bundle
您现在应该在手动添加修复之前尝试一下，也许会添加更改。
此外，您可以使用我在答案开头给出的关于 Composer 和 VCS 的链接，并直接要求修复。这是您自己的赞赏，因为它是目前的解决方案。
最后，请耐心等待，修复将很快合并到稳定版本中。
