When attempting to load the page, I'm getting the error that the ReflectionException Class / does not exist (open: /var/www/laravel_guestbook/vendor/laravel/framework/src/Illuminate/Routing/ControllerInspector.php), could use some insight on what is causing this error.
Furthermore, I've also run 'composer dump-autoload' at the root of my project folder to no avail.
routes.php
Route::controller('EntriesController', '/');
Entry.php
<?php
class Entry extends Eloquent {
/**
* The database table used by the model.
*
* #var string
*/
protected $table = 'entries';
}
?>
home.blade.php
<html>
<head>
<title>Laravel 4 Guestbook</title>
</head>
<body>
#foreach ($entries as $entry)
<p>{{ $entry->comment }}</p>
<p>Posted on {{ $entry->created_at->format('M jS, Y') }} by
{{ $entry->username}}
</p><hr>
#endforeach
<form action="/" method="post">

</table>
</form>
</body>
EntriesController.php
<?php
class EntriesController extends BaseController {
# Handles "GET /" request
public function getIndex()
{
return View::make('home')
->with('entries', Entry::all());
}
# Handles "POST /" request
public function postIndex()
{
// get form input data
$entry = array(
'username' => Input::get('frmName'),
'email' => Input::get('frmEmail'),
'comment' => Input::get('frmComment'),
);
// save the guestbook entry to the database
Entry::create($entry);
return Redirect::to('/');
}
}
?>
It's suppose to be:
Route::controller('/', 'EntriesController');
If your naming is correct but you still get this type of error do a
composer update
This command will refresh your composer autoload files (among others).
In my case the name of the file was PostController.php, but inside I had
class Post extends \BaseController {
Instead of
class PostController extends \BaseController {
I had to rename the file as "php artisan generate:controller " command requires the word controller to be specified.

The application is web-application using spring boot and thymeleaf. The application has a questionnaire along with some fields that needs to filled to submit the form. The model object (here answeredQuestionnaire) in template th:object="${answeredQuestionnaire}" has nested objects with as shown below.
When I submit the form, I need to assign the questionId and possibleAnswerId to answers (Set) in answeredQuestionnaire. How can I assign this in thymeleaf template. Please provide some suggestions.
AnsweredQuestionnaire .java
public class AnsweredQuestionnaire {
private UUID id;
private Boolean isRirelevant;
private Boolean isITrelevant;
private String descriptionProcess;
private int classCalculated;
private LocalDateTime createdDateAndTime;
private Questionnaire questionnaire;//separate model class
private Process process;//separate model class
private Set<Answer> answers = new HashSet<>();// Set of separate model class
}
Answer.java
public class Answer {
private UUID id;
private Question question;// separate class
private PossibleAnswer selectedPossibleAnswer;// separate class
private String answerComment;
private AnsweredQuestionnaire answeredQuestionnaire;
}
The controller handler to display the questionnaire page is as shown below.
#GetMapping("/review/process/{id}")
public String reviewProcess(#PathVariable UUID id, Model model){
Process byId = processService.findById(id);
if(byId != null){
if(byId.getAnsweredQuestionnaires().size() > 0){
Set<AnsweredQuestionnaire> answeredQuestionnaires = byId.getAnsweredQuestionnaires();
AnsweredQuestionnaire lastUpdatedAnsweredQuestionnaire = answeredQuestionnaires.stream().sorted(Comparator.comparing(AnsweredQuestionnaire::getCreatedDateAndTime).reversed())
.collect(Collectors.toList()).get(0);
System.out.println("AnsweredQuestionnaire for a given process :"+lastUpdatedAnsweredQuestionnaire);
model.addAttribute("answeredQuestionnaire", lastUpdatedAnsweredQuestionnaire);
model.addAttribute("isIT_SiG_relevant", lastUpdatedAnsweredQuestionnaire.getIsIT_SiG_relevant());
model.addAttribute("isRiDARrelevant", lastUpdatedAnsweredQuestionnaire.getIsRiDARrelevant());
model.addAttribute("possibleAnswersIds", getAllSelectedPossibleAnswersWithId(lastUpdatedAnsweredQuestionnaire.getAnswers()) );
}else{
System.out.println("Process without answeredQuestionnaire");
Questionnaire byIsActive = questionnaireService.findByIsActive(true);
AnsweredQuestionnaire emptyAnsweredQuestionnaire = new AnsweredQuestionnaire();
emptyAnsweredQuestionnaire.addQuestionnaireForAnsweredQuestionnaire(byIsActive);
System.out.println("Questionnaire found"+byIsActive);
model.addAttribute("answeredQuestionnaire", emptyAnsweredQuestionnaire);
model.addAttribute("isIT_relevant", false);
model.addAttribute("isRi_relevant", false);
// model.addAttribute("questionnaire", byIsActive);
model.addAttribute("possibleAnswersIds", getAllSelectedPossibleAnswersWithId(emptyAnsweredQuestionnaire.getAnswers()) );
}

Some suggestions :
1/ You should use Command objects or DTO and not Entity from your model directly to bind datas from your web forms.
2/ You should use a List to bind datamodel relations, it works with Thymeleaf but Set will not work.
3/ You can manage relations with DTO which are containing subsets of your model objects, and simplify the business process a lot and the wireload to your services and database(s). It depends how your model are related too btw.
4/ Disable OpenSessionInView and make a service layer with Transactional annotated methods
5/ Never use an Entity inside a Controller. It's an architectural conception's nonsense.
I have added this form in twig, i need to know if this is okay and how can i recupere the input name="comments" in controller
<form action="{{ path('Update') }}" method="POST">
<input class="form-control" type="text" name="comments"
value=""></td>
<td>
<input type="submit" value="Save"/>
</form>
You can take a look at the Symfony Request Object section of the doc:
// retrieves $_GET and $_POST variables respectively
$request->query->get('id');
$request->request->get('category', 'default category');
So you can retrieve in the controller as:
$request->request->get('comments');
In your controller you can use the Request object to get all the parameters of your form, for example:
/**
* #Route("/Update")
*/
public function update(Request $request){
$comments = $request->request->get('comments');
...
}
But I recommend you to use the forms component.
I have searched multiple questions similar to my question but it still doesn't solve it.
Here is my web.php (route)
Route::get('/page/dpage1','ApplyProgramController#index')->name('dpage1');
Route::get('/page/dpage1', 'ApplyProgramController#create');
Route::post('/page/dpage1','ApplyProgramController#store');
My blade.php
<tr>
<strong>
<th>Kod Program</th>
<th>Nama Program</th>
<th>Jawatan</th>
<th>Mohon</th>
</strong>
</tr>
#foreach($programs as $program)
<tr>
<td><strong> Kod Program : {{ $program->kod_program}}</strong></td>
<td>
<input type="text" name="kod_program" readonly value="{{ $program->kod_program}}" class="form-control"></td>
<td><strong> Nama Program :</strong></td>
<td>
<input type="text" name="nama_program" readonly value="{{ $program->nama_program}}" class="form-control"></td>
</tr>
<td>
The error is at the row #foreach($programs as $program).
Here is my controller php
class ApplyProgramController extends Controller
{
public function index()
{
$programs = Program::all();
dd($programs);
return view('page.dropdown1',compact('programs');
I tried several methods such as changing compact to ['programs'=>$program]. When I tried using ifisset($programs), I am able to view the blade page but there is no data shown on the page from my database. The code earlier can be used from the other pages.
I have the following controller:
<?php
namespace Dev\TaskBundle\Controller;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Session\Session;
use Dev\TaskBundle\Entity\User;
class UserController extends Controller
{
/**
* Redirects to directory where you can input new password
*
* #Route("/{id}", name="user_update")
*/
public function userUpdatePanel($id)
{
$user = $this->getDoctrine()->getRepository('DevTaskBundle:User')->find($id);
return $this->render('DevTaskBundle:User:userUpdate.html.twig', array('user' => $user));
}
/**
* Updates password of the user
*
* #Route("/updatePassword", name="updatePass_action")
*/
public function passUpdateAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$id = $request->get('id');
$user = new User();
$user = $em->getRepository('DevTaskBundle:User')->find($id);
$password = $request->get('passInput');
$user->setPassword($password);
$em->flush();
$users = $this->getDoctrine()->getRepository('DevTaskBundle:User')->findAll();
return $this->render('DevTaskBundle:User:accounts.html.twig', array('users' => $users));
}
}
Here is form from userUpdate.html.twig
<form action="{{ path('updatePass_action') }}" method="POST">
<div>
Username: {{ user.username }}
</div>
<input type="hidden" name="id" value="{{user.id}}">
<div class="form-group">
<label for="passInput">Password:</label>
<input type="text" class="form-control" id="passInput" name="passInput" value="{{ user.password }}">
</div>
<button type="submit" class="btn btn-default">Change</button>
</form>
and when I proceed to change the password I receive such error
Impossible to access an attribute ("username") on a null variable in DevTaskBundle:User:userUpdate.html.twig at line 23
After changing the password I want to render accounts.html.twig so why there is the error about userUpdate? What is wrong here?
Part of accounts.html.twig with twig scripts:
<table class="table table-bordered">
<thead>
<tr>
<th>Login</th>
<th>Hasło</th>
<th>Narzędzia</th>
</tr>
</thead>
<tbody>
{% for user in users %}
<tr>
<td>
{{ user.username }}
</td>
<td>
{{ user.password }}
</td>
<td>
<a href="{{ path('user_update', {'id': user.id}) }}" >
<span class="glyphicon glyphicon-pencil linkDeco" ></span>
</a>
{% if user.status == 1 %}
<a href="{{ path('deleteAction', {'name': 'User' ,'direction': 'account_panel' , 'id': user.id}) }}" >
<span class="glyphicon glyphicon-trash linkDeco"></span>
</a>
{% endif %}
</td>
</tr>
{% endfor %}
</tbody>
</table>
EDIT
problem must be related to userUpdate.html.twig because when I deleted
<div>
Username: {{ user.username }}
</div>
I have the error
Impossible to access an attribute ("id") on a null variable in DevTaskBundle:User:userUpdate.html.twig at line 24
Any idea why is that?
Doctrine find method return array of objects, use findOne instead of find when you expecting only one result.
$user = $this->getDoctrine()->getRepository('DevTaskBundle:User')->findOneById($id);
I'm using Thymeleaf 2.1.2.RELEASE with Spring MVC 4.0.4.RELEASE
I have a dynamic form that I use to add new order lines to an order.
The problem I am facing is that each time I add a line and the content is re-rendered then an extra symbol is added before the currency symbol on the price column of each of the previous lines.
So if I add three rows i get
£22.00
£22.00
£22.00
The price field is BigDecimal with #NumberFormat(style = NumberFormat.Style.CURRENCY) so Spring should handle the conversion.
<div>
<label th:text="#{order.lines}">Order Lines</label>
<table id="addTable" dt:table="true" dt:sort="false" dt:paginate="false" dt:info="false" dt:lengthchange="false">
<thead>
<tr>
<th th:text="#{order.lines.head.linenum}">line</th>
<th th:text="#{order.lines.head.product}">Product</th>
<th th:text="#{order.lines.head.description}">Description</th>
<th th:text="#{order.lines.head.quantity}">Quantity</th>
<th th:text="#{order.lines.head.price}">Price</th>
<th>
<button type="submit" name="addLine" th:text="#{order.line.add}">Add line</button>
</th>
</tr>
</thead>
<tbody>
<tr th:each="line,lineStat : *{lines}">
<td th:text="${lineStat.count}">1</td>
<td>
<input type="text" th:field="*{lines[__${lineStat.index}__].productIdentifier}"
th:errorclass="fieldError"/>
</td>
<td>
<input type="text" th:field="*{lines[__${lineStat.index}__].description}"
th:errorclass="fieldError"/>
</td>
<td>
<input type="text" th:field="*{lines[__${lineStat.index}__].quantity}"
th:errorclass="fieldError"/>
</td>
<td>
<input type="text" th:field="*{{lines[__${lineStat.index}__].price}}"
th:errorclass="fieldError"/>
</td>
<td>
<button type="submit" name="removeLine" th:value="${lineStat.index}"
th:text="#{order.line.remove}">Remove line
</button>
</td>
</tr>
</tbody>
</table>
</div>
This is then backed by class with
public class OrderLine implements Serializable {
#NotEmpty
private String description;
#NotNull
#NumberFormat(style = NumberFormat.Style.CURRENCY)
private BigDecimal price;
#NotEmpty
private String productIdentifier;
#NotNull
#Min(value = 1)
private Integer quantity;
and then in my controller
#RequestMapping(value="/customer/orders", params={"addLine"})
public String addLine(final Order order, final BindingResult bindingResult) {
order.getLines().add(new OrderLine());
return "customer/orders";
}
The html page aleady includes
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
and the character encoding servlet filter is set up as below
#Override
protected Filter[] getServletFilters() {
CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
characterEncodingFilter.setEncoding("UTF-8");
characterEncodingFilter.setForceEncoding(true);
return new Filter[] {characterEncodingFilter};
}
Further to this from using Fiddler I can see that the response header to the dandelion datatables ajax request is incorrectly encoded as ISO-88591. I'm using datatables-thymeleaf 0.93 with datatables 1.9.4
From experimenting if I set thymeleaf encoding, the spring servlet filter and the html meta tag to ISO-88591 then the currency symbol appears correctly rendered although I would like this to work with UTF-8
Eventually I found an answer in this post CharacterEncodingFilter don't work together with Spring Security 3.2.0 provided by #Christian Nilsson. Basically I needed to force the character encoding filter to be registered using the onStartup method rather than the usual getServletFilters.
