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
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:
"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?
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:
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?
you are persisting $ipde which happens to be a form not an entity !
that's probably the source of error.
