Failed on insert entity with many related entities - symfony

Question

This is my first post because until now I had always found solution with your answers, until now...
I have three Entities (Bike, Category and Extra) that have some field translatable. I know there is a Translatable Extension in symfony but I discovered a bit late and I have my solution always working.
The thing is I have then 3 other tables (BikeI18N, CategoryI18N and ExtraI18N). These table link with their associated with a column bike_id (for example). Here you have the schema of Bike and Category and their I18N's tables:
Bike:
BEM\BikeBundle\Entity\Bike:
type: entity
table: null
fields:
id:
type: integer
id: true
generator:
strategy: AUTO
marca:
type: string
length: 255
model:
type: string
length: 255
preu1Dia:
type: float
column: preu_1dia
[...]
manyToOne:
category:
targetEntity: BEM\CategoryBundle\Entity\Category
inversedBy: bikes
oneToMany:
translation:
targetEntity: BikeI18N
mappedBy: bike
cascade: [persist]
pedals:
targetEntity: Pedal
mappedBy: bike
talles:
targetEntity: Talla
mappedBy: bike
manyToMany:
accessoris:
targetEntity: Accessori
inversedBy: bikes
lifecycleCallbacks: { }
BikeI18N:
BEM\BikeBundle\Entity\BikeI18N:
type: entity
table: null
fields:
id:
type: integer
id: true
generator:
strategy: AUTO
descripcio:
type: text
locale:
type: string
length: '2'
manyToOne:
bike:
targetEntity: Bike
inversedBy: translation
joinColumn:
bike_id:
referencedColumnName: id
lifecycleCallbacks: { }
Category:
BEM\CategoryBundle\Entity\Category:
type: entity
table: null
repositoryClass: BEM\CategoryBundle\Repository\CategoryRepository
fields:
id:
type: integer
id: true
generator:
strategy: AUTO
oneToMany:
translation:
targetEntity: CategoryI18N
mappedBy: category
cascade: [persist]
bikes:
targetEntity: BEM\BikeBundle\Entity\Bike
mappedBy: category
lifecycleCallbacks: { }
and finally CategoryI18N:
BEM\CategoryBundle\Entity\CategoryI18N:
type: entity
table: null
fields:
id:
type: integer
id: true
generator:
strategy: AUTO
categoryId:
type: integer
column: category_id
locale:
type: string
length: '2'
translation:
type: string
length: 255
manyToOne:
category:
targetEntity: Category
inversedBy: translation
joinColumn:
category_id:
referencedColumnName: id
lifecycleCallbacks: { }
In my "new" form I have a Category form with 4 embeded CategoryI18N forms. It works properly. The problem is the Bike and BikeI18N does not even if I did the same.
If I write $translation->setAccessori($this); in Bike::addTranslation(BikeI18N $translation) I get the error Entities passed to the choice field must be managed. Maybe persist them in the entity manager?.
If I don't write $translation->setAccessori($this); the form is saved but the relation is lost or, if I set the DB to not_nullable bike_id I get an error.
The most surprising thing that makes no sense to me is that I have setCategory($this) inside the addTranslation of the class Category...any ideas?

Answer 1

I resolved the issue.
The think was in my BikeI18N form builder.
class BikeI18NType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('descripcio')
->add('locale', 'hidden')
//->add('bike', 'hidden')
;
}
}
When I commented out the bike additions the problem was solved.
Thanks for reading!
