Symfony2 自定义表单。想念的想法

Question

我有两个实体如下：

会员（姓名、名字）：OneToMany -> 订阅

订阅（numberOfMounth）：（ManyToOne -> 会员）

我想创建一个表单来加载成员列表。 并且对于每个成员，我可以选择订阅月数（numberOfMounth）。 在每个成员之前带有一个复选框以仅选择那些准备订阅的成员。最后是一个记录所有内容的按钮。

我首先通过添加字段集合（订阅）来创建表单。 但我想知道是否要为这个表单创建一个新实体。

其实我错过了一些想法。

我的实体和形式：

新更新：我的控制器和视图

public function subscriptionAction()
{    
    $entity = new Subscription();

    $repository = $this->getDoctrine()
                       ->getRepository('JackAikidoBundle:Member');

    $members = $repository->findAll();

    $formBuilderPratSub = $this->createFormBuilder();

    //Make a loop for each $member
    foreach($members as $member)
    {
        $formBuilder = $this->get('form.factory')->createNamedBuilder(
                $member->getId(), 
                new SubscriptionType(), 
                $entity
                );
        $formBuilderPratSub->add($formBuilder);
    }
    //Create the form

    $form = $formBuilderPratSub->getForm();
    $form->add('submit', 'submit', array('label' => 'Create'));

    return $this->render('JackAikidoBundle:Aikido:souscription.html.twig', 
        array(
            'entity' => $entity,
            'forms'   => $form->createView(),
            'members' => $members,
    ));

}

我的看法：

    <table class="table">
        <thead>
            <tr>
                <th>Member ID</th>
                <th>Name</th>
                <th>Firstname</th>
                <th>Nb Month</th>
            </tr>
        </thead>
        <tbody>
            {% for member in members %}
                {% for form in forms %}
                    <tr>
                        <td>{{ member.id }}</td>
                        <td>{{ member.nom }}</td>
                        <td>{{ member.prenom }}</td>
                        <td>{{ form_row(form.nbMonth)}}</td>
                    </tr>

                {% endfor %}

            {% endfor %}
        </tbody>
    </table>
   <div>{{ form_row(forms.submit) }}</div> 

错误：

Method "nbMonth" for object "Symfony\Component\Form\FormView" does not exist in JackAikidoBundle:Aikido:souscription.html.twig at line 25 

这一行是：<td>{{ form_row(form.nbMonth)}}</td>

我尝试：{{ form(forms)}} 只显示表单：

Answer 1

我尝试了一些我认为不是好的方法：

在控制器中：

public function subscriptionAction(Request $request)
{    
    $repository = $this->getDoctrine()->getRepository('JackAikidoBundle:Member');
    $members = $repository->findAll();
    $em = $this->getDoctrine()->getManager();

    if ($request->getMethod() == 'POST') {
        $nbMonth = $this->getRequest()->get('nbMonth');
        $selectedMembers = $this->getRequest()->get('selectedMembers');

        for($i =0; $i < count($selectedMembers); $i++){
            $subscription = new Subscription();
            $subscription->setMonth((int)$nbMonth[$i]);
            $member = $repository->find($selectedMembers[$i]);
            $subscription->setMember($member);
            $em->persist($subscription);
        }
        $em->flush();

    } 
    return $this->render('JackAikidoBundle:Aikido:subscription.html.twig', 
        array(
            'members' => $members,
    ));  
}

在视图中：

<form  action='{{path('jack_aikido_subscription')}}' method="post">
    <table class="table table-bordered table-striped table-primary list-table">
        <thead>
            <tr>
                <th>Select</th>
                <th>Name</th>
                <th>Firstname</th>
                <th>Nb Month</th>
            </tr>
        </thead>
        <tbody>
            {% for member in members %}               
                    <tr>
                        <td>
                            <input type="checkbox"  name="selectedMembers[]" value="{{ member.id }}">
                        </td>
                        <td>{{ member.name }}</td>
                        <td>{{ member.firstname }}</td>
                        <td>
                            <select name="nbMonth[]">
                                <option value="0">Select</option>
                            {% for i in 1..12 %}
                                <option value="{{ i }}">{{ i }} month</option>
                            {% endfor %}    
                            </select>
                        </td>
                    </tr>
            {% endfor %}
        </tbody>
    </table>
    <input type="submit" name="save">    
</form> 

它有效，但我仍在等待最佳答案。
