I have a basic symfony2 form where I can set a value for my field.
I've just figured out that null values where saved as empty strings, where I expect an exception to be raised because thenull value is not accepted.
My mapping (within a trait) :
/**
* #ORM\Column(name="name", type="string", length=100, nullable=false)
*/
protected $name;
My field :
->add('name', null, array(
'label'=>'Nom détaillé',
'required' => false))
Setting required to true and defining assert rules works well but here I'm trying to solve this conversion issue.
If I put a vardumpin the SetName method, I do get a null value which is later saved as an empty string in my database. How can I solve that ?

Seems like you just need to add a strict equivalence check === against the variable and then throw new Exception() if it's null

You don't need to specify the FOREIGN KEY keyword here.
alter table order_products drop key order_products_product_id_foreign;
It's not a foreign key. so execute the line.
ALTER TABLE order_products DROP KEY order_products_product_id_foreign

I want to assign referential integrity to bank_api_uat_user table each time i add constraint it gives below error
MySQL said: Documentation

Below query used to create foreign key.
ALTER TABLE `bank_api_uat_user` ADD CONSTRAINT `const_file_role` FOREIGN KEY (`role`) REFERENCES `test`.`create_role`(`Role_code`) ON DELETE SET NULL ON UPDATE SET NULL;
Its important to make a child column Null for setting null reference option.
the above queries work if role is declared as NULL

The problem is that some of the columns: entidad_id, cargo_id, etc, are declared as NULL and when i set the FK, laravel created them as NOT NULL.
Is anyting here that i am missing??
Sorry for being late.
You have typos in code
nulleable
$table->integer('entidad_id')->nulleable()->unsigned();
should be
nullable
$table->integer('entidad_id')->nullable()->unsigned();
Don't know why Laravel is not yelling on typos :(
I'm working a project with Yiiframwork and I have this table in my data base project

I only use 'comment' because I found it in a tutorial for a yii framework project.
I have got the attribute 'idEntreprise' as FK in my DB but when I entred other 'idEntreprise' that does note exist in my table entreprise it was not problem, instead it must be a problem.
So I added 'identreprise' as Fk and that have this problem now.
Hope you understand my problem :/
can any one helep me plz !!
To define a foreign key on a column, it must fulfil some conditions.
Child and parent column must have same column definition by type,
signed.
Parent column must have an index defined on it.
Make sure that
The column tbl_entreprise.id is indexed.
The column definition idEntreprise tinyint(3) unsigned in tbl_annonce matches
with that of tbl_entreprise.id

what i am trying to do is make the field ROOM_ID from enrollment and subjects foreign key and the reference be the ID from room.. the ROOM_ID must not be unique...
i am getting this error
#1452 - Cannot add or update a child row: a foreign key constraint fails (`enrollmentdb`.`#sql-277_164`, CONSTRAINT `#sql-277_164_ibfk_3` FOREIGN KEY (`ROOM_ID`) REFERENCES `room` (`ID`))
when i am using this SQL command:
ALTER TABLE enrollment
ADD FOREIGN KEY (room_id)
REFERENCES room(ID)
Try below code if its working :
ALTER TABLE enrollment
ADD CONSTRAINT ROOM_ID_fk
FOREIGN KEY(ROOM_ID)
REFERENCES room(ID);
Thanks!
room_id is capitalised in your table. Try:
ALTER TABLE enrollment
ADD FOREIGN KEY (ROOM_ID)
REFERENCES room(ID)
replace 'room_id' with 'ROOM_ID'
