类 'Symfony\Component\Form\Form'在表单提交期间未在链配置的命名空间中找到 [英] The class 'Symfony\Component\Form\Form' was not found in the chain configured namespaces during Form Submission
本文介绍了类 'Symfony\Component\Form\Form'在表单提交期间未在链配置的命名空间中找到的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在构建一个界面，允许办公室中的人编辑特定记录的详细信息.目前我有一个这样的表格:
view.html.twig
<div id="editPersonal" style="display:none;"><div class="modal-head"><h2>编辑个人详细信息:<font-color="red !important">{{instructor.firstName}} {{instructor.surname}}</font></h2><div class="modal-body"><form action="#" method="post" {{ form_enctype(ipde) }} id="editPersonalDetails" class="modaledit"><table class="modalform-col1">
<div class="modal-footer"><div class="modal-placeright"><a href="#close" rel="modal:close" class="closebutton">关闭而不保存</a><input type="submit" value="Save Changes" id="savebuttonpr" class="savebutton"/>{{ form_rest(ipde) }}
我的控制器看起来像这样:
DefaultController.php
getDoctrine()->getManager();//从实体获取 Instructor 以供表单使用$instructorQ = $insrep->getRepository('InstructorBundle:MapInstructors')->find($instructor);//从实体获取共享分支以供表单使用$instructorS = $insrep->getRepository('InstructorBundle:MapInstructorShared')->find($instructor);//生成表格以编辑教师个人信息$ipde = $this->createForm( new IpdeType(), $instructorQ);//处理表单提交以编辑教师个人详细信息if ($request->getMethod() == 'POST') {$ipde->bind($request);如果 ($ipde->isValid()) {//执行一些操作，例如将任务保存到数据库//if ($this->request->isXmlHttpRequest()){//返回ajax需要的数据.//}$em = $this->getDoctrine()->getManager();$em->persist($ipde);$em->flush();返回 $this->redirect($this->generateUrl('task_success'));}}//生成表格以编辑教师记录$ir = $this->createForm( new IrType(), $instructorQ);//生成表格以编辑教师记录$ba = $this->createForm( new BaType(), $instructorS);//返回数据查看return $this->render('InstructorBundle:Default:view.html.twig', array('ipde' =>$ipde->createView(),'ir' =>$ir->createView(),'巴' =>$ba->createView()));}}但是，当我提交表单时，出现以下错误:
<块引用>"在链中找不到类 'Symfony\Component\Form\Form'配置的命名空间 PCUK\InstructorBundle\Entity"
我之前已经构建了一个 Symfony2 项目，并且我已经将它引用到当前的项目中，以查看是否包含了 Symfony\Component\Form\Form，如果这确实是问题所在.
发生了什么?
解决方案
您正在持久化 $ipde 这恰好是一个表单而不是一个实体！
这可能是错误的根源.
I'm building an interface that will allow people in the office to edit details of specific records. Currently I have a form like this:
view.html.twig
<!-- Modal Windows: Edit Instructor Personal Details -->
<div id="editPersonal" style="display:none;">
<div class="modal-head">
<h2>Edit Personal Details For: <font-color="red !important">{{instructor.firstName}} {{instructor.surname}}</font></h2>
</div>
<div class="modal-body">
<form action="#" method="post" {{ form_enctype(ipde) }} id="editPersonalDetails" class="modaledit">
<table class="modalform-col1">
<tbody>
<tr class="hidden">
<th>{{ form_label(ipde.id, 'ID*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.id) }}
{{ form_widget(ipde.id, { 'attr': {'class': 'textfield'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.firstName, 'First Name*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.firstName) }}
{{ form_widget(ipde.firstName, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.surname, 'Surname*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.surname) }}
{{ form_widget(ipde.surname, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.address1, 'Address Line 1*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.address1) }}
{{ form_widget(ipde.address1, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.address2, 'Address Line 2', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.address2) }}
{{ form_widget(ipde.address2, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.town, 'Town*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.town) }}
{{ form_widget(ipde.town, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.county, 'County*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.county) }}
{{ form_widget(ipde.county, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.postcode, 'Postcode*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.postcode) }}
{{ form_widget(ipde.postcode, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.email, 'Email*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.email) }}
{{ form_widget(ipde.email, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
</tbody>
</table>
</div>
<div class="modal-footer">
<div class="modal-placeright">
<a href="#close" rel="modal:close" class="closebutton">Close Without Saving</a>
<input type="submit" value="Save Changes" id="savebuttonpr" class="savebutton" />
{{ form_rest(ipde) }}
</div>
</div>
</div>
And my Controller looks like this:
DefaultController.php
<?php
namespace PCUK\InstructorBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use PCUK\InstructorBundle\Form\IpdeType;
use PCUK\InstructorBundle\Form\IrType;
use PCUK\InstructorBundle\Form\BaType;
use Symfony\Component\HttpFoundation\Request;
class DefaultController extends Controller
{
public function viewAction($instructor, Request $request)
{
// Database connection
$insrep = $this->getDoctrine()->getManager();
// Get Instructor from Entity for Form use
$instructorQ = $insrep->getRepository('InstructorBundle:MapInstructors')->find($instructor);
// Get Shared Branches from Entity for Form use
$instructorS = $insrep->getRepository('InstructorBundle:MapInstructorShared')->find($instructor);
// Generate Form to edit Instructor Personal Details
$ipde = $this->createForm( new IpdeType(), $instructorQ);
// Handle Form submission to edit Instructor Personal Details
if ($request->getMethod() == 'POST') {
$ipde->bind($request);
if ($ipde->isValid()) {
// perform some action, such as saving the task to the database
//if ($this->request->isXmlHttpRequest()){
//return data ajax requires.
//}
$em = $this->getDoctrine()->getManager();
$em->persist($ipde);
$em->flush();
return $this->redirect($this->generateUrl('task_success'));
}
}
// Generate Form to edit Instructor Records
$ir = $this->createForm( new IrType(), $instructorQ);
// Generate Form to edit Instructor Records
$ba = $this->createForm( new BaType(), $instructorS);
// Return data to view
return $this->render('InstructorBundle:Default:view.html.twig', array(
'ipde' => $ipde->createView(),
'ir' => $ir->createView(),
'ba' => $ba->createView()
));
}
}
However, when I go to submit the form I get the following error:
"The class 'Symfony\Component\Form\Form' was not found in the chain configured namespaces PCUK\InstructorBundle\Entity"
I have built a Symfony2 project before and I've referenced it against this current project to see if I've included the Symfony\Component\Form\Form, if that's actually what the problem is.
What's happening?
解决方案
you are persisting $ipde which happens to be a form not an entity !
that's probably the source of error.
