How to create a form with multiple rows of one entity in Symfony2

Question

First I\'ve read documents for both Collection Field Type and How to Embed a Collection of Forms ... The example is about one entity (Task) that has one-to-many relation wit

Answer 1

Here's a start on a possible solution. The example below takes a single entity Skills and presents all of them on a single page. What I don't know is whether this technique can be used to persist children objects. I would expect one could loop through the returned data and persist as required.

The code below results in a page with a list of all possible Skills and a checkbox for declaring each enabled or enabled.

In a controller:

    $skills = $em->getRepository("TruckeeMatchingBundle:Skill")->getSkills();
    $formSkills = $this->createForm(new SkillsType(), array('skills' => $skills));
    ...
        if ($request->getMethod() == 'POST') {
            $formSkills->handleRequest($request);
            foreach ($skills as $existingSkill) {
                $em->persist($existingSkill);
            }
        }
    ...
    return ['formSkills' => $formSkills->createView(),...]

In a template:

{% for skill in formSkills.skills %}
    {{ skill.vars.value.skill }}
