How can I perform an inline editing inside a nested admin?

Question

My problem is the following. I am using Sonata Admin with Symfony. In the Admin section, when I try to create an entity, nothing appears when I click on the add button (spelled "Ajouter"):

I get the following error: Call to a member function getName() on a non-object in the chrome console

Here's how my entities hierarchy is, I have three objects that are linked together in the following way:

Video ---OneToOne--> String ---OneToMany--> LocalizedString 

Simply, I have one video that will have a title and this title will be translated. Here are my entities:

LocalizedString

OSC\UtilsBundle\Entity\LocalizedString:     type: entity     table: null     repositoryClass: OSC\UtilsBundle\Entity\LocalizedStringRepository     id:         id:             type: integer             id: true             generator:                 strategy: AUTO     fields:         locale:             type: string             length: '20'         content:             type: string             length: 255      manyToOne:         parent:             targetEntity: String             mappedBy: localizedObjects       lifecycleCallbacks: {  } 

String

OSC\UtilsBundle\Entity\String:     type: entity     table: null     repositoryClass: OSC\UtilsBundle\Entity\StringRepository     id:         id:             type: integer             id: true             generator:                 strategy: AUTO      oneToMany:         localizedObjects:             targetEntity: LocalizedString             mappedBy: parent             cascade: ["persist", "remove"]      lifecycleCallbacks: {  } 

Video

OSC\MySportBundle\Entity\Video:     type: entity     table: null     repositoryClass: OSC\MySportBundle\Entity\VideoRepository     id:         id:             type: integer             id: true             generator:                 strategy: AUTO      oneToOne:         title:             targetEntity: OSC\UtilsBundle\Entity\String             cascade: ["persist", "remove"]      lifecycleCallbacks: {  } 

So, I did this structure to facilitate the editing in SonataAdmin. If, through the admin dashboard, I want to edit a String, I can easily edit a string and translate it in many languages (this already works).

However, when I try to do that in the video admin, it seems that I cannot do inline editing (clicking the add button does not work) of the String object.

Here's the relevant code in video admin class:

$formMapper         ->add('title', 'sonata_type_admin', array('delete' => false, 'btn_add' =>false), array(             'edit' => 'inline',             'inline' => 'table',         )); 

From what I have found, it looks like two imbricated forms are not possible ? Is there a way to circumvent that restriction ? Or maybe it is my design that is not too good ?

Edit1: It looks like there is a patch coming on github: https://github.com/sonata-project/SonataAdminBundle/pull/1971#issuecomment-58023124

If anyone knows how I can use it I would appreciate.

In your code you are using delete which is not a valid option. Maybe you can try 'btn_delete' => false Check the documentation for all the valid options here.

If this not working, maybe sonata_type_collection is the solution to your problem. Ensure that you are using the by_reference option the correct way depending on your relation.
