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.
Answer：
Try this in the form mapper :
$formMapper
->add('title', 'sonata_type_model_list', array(
'class' => 'YourBundle:String',
'required' => false,
'delete' => false,
'btn_add' =>true,
), array(
'edit' => 'inline',
'inline' => 'table',
))
;
If the error persist try to get a look at the Doctrine2 documentation :
Doctrine2 One to One association mapping and then generate your entities
Answer：
You said that chrome console gives you error:
Call to a member function getName() on a non-object
So this error is not from javascript?
If error from PHP it means that when you try $object->getName() (it must by in OSC\UtilsBundle\Controller use Ctr+f “getName()” in file editor to find that line) $object is not an object, that can by because you maybe get obeject array, not single object. Try add var_dump($object); and you see what is it.
