i have:

/** * @ContentEntityType( * id = "my_entity", * label = @Translation("drwywr werwer label"), * bundle_label = @Translation("My entity type"), * handlers = { * bla... * "form" = { * "default" = "Drupal\my_entity\Form\MyEntityForm", * "edit" = "Drupal\my_entity\Form\MyEntityForm", * "delete" = "Drupal\Core\Entity\ContentEntityDeleteForm" * }, * bla... * }, * translatable = FALSE, * entity_keys = { bla... }, * bundle_entity_type = "my_entity_type", * links = { * "collection" = "/admin/test/entity/collection", * "canonical" = "/admin/test/entity/{my_entity}", * "edit-form" = "/admin/test/entity/{my_entity}/edit", * "delete-form" = "/admin/test/entity/{my_entity}/delete" * } * ) */

based on above, how do i load my entity in form below:

<?php namespace Drupal\my_entity\Form; use bla... /** * Form controller for the node edit forms. */ class MyEntityForm extends ContentEntityForm { //how to load my entity type here? }

i tried a couple way but i keep receiving:

Error: Call to a member function getEntityTypeId() on null

mainly because the entity is not loaded (null value)

this is how i create the route:

in my_entity.routing.yml:

route_callbacks: - 'entity.my_entity.routes::routes'

in routes:

public function routes() { // Build Entity Create Route - CREATE $route = new Route( (substr($type->getRoute()['path'], -1) == '/' ? $type->getRoute()['path'] . $type->id() : $type->getRoute()['path'] . '/' . $type->id()) . '/create', [ '_form' => '\Drupal\my_entity\Form\MyEntityForm', //TODO : not finish 'entity_type' => 'my_entity', 'bundle' => $type->id(), '_title' => 'Create ' . $type->getRoute()['label'], ], ['_permission' => 'entity admin settings'] ); $route_collection->add('entity.my_entity.' . $type->id() . '_create', $route); }

if you see in my content entity type config above, i have:

 * links = { * "collection" = "/admin/test/entity/collection", * "canonical" = "/admin/test/entity/{my_entity}", * "edit-form" = "/admin/test/entity/{my_entity}/edit", * "delete-form" = "/admin/test/entity/{my_entity}/delete" * }

which i want those: edit, delete to be able to 'link' with my form as well - how to do this?

what i'm trying to achieve is: to generate forms based on field define in my entity type

  • How is your route defined? Please add your definition to the question. Commented May 1, 2017 at 6:01
  • Also the form class (ArmEntityForm) is not mentioned in the form handlers section of the entity. Commented May 1, 2017 at 6:01
  • Sorry the class in my php snippet is MyEntityForm it is typo. I have fix it, the route is generated based on links in contententitytype config Commented May 1, 2017 at 6:15
  • Please add the definition for the form route. I cannot help you if i can't see how you defined the route for the form. Commented May 1, 2017 at 6:46
  • Thanks @Eyal, I have updated my question above to explain how i build the route Commented May 1, 2017 at 11:08

Your code currently loads the form with the _form routing definition. For classes extending ContentEntityForm, you have to use the _entity_form notation instead. Here is an example of an 'module_name.routing.yml' file:

kollektivhampel.pdf_erstellen_form: path: '/intranet/{my_entity}/something' defaults: _entity_form: 'my_entity.default' _title: 'Your page title' options: parameters: my_entity: type: my_entity requirements: _permission: 'some permission defined in your module_name.permissions.yml file'

The _entity_form is composed of two parts: before the dot, you have the entity type id, in this example my_entity. Behind the dot, you have the name of the form, defined in the handlers section of the @ContentEntityType annotation. In this case, the second part is default, According to your question's code, this refers to \Drupal\my_entity\Form\MyEntityForm. You might not need the route_callbacks code, as a static routing directly in the yml file is probably enough.

You can take a look into core/modules/system/tests/modules/entity_test/src/EntityTestForm.php file.

And you can see that in the object that is an instance of ContentEntityForm it possible to get an entity object using $entity property: 

$entity = $this->entity; $entity = $this->getEntity();
