How do I remove the foreign key constraint?

Thanks for great tut.

But unfortunately I have a problem with my relations. I can’t figure what the problem is, and its most likely something stupid that I did. Any help will be great.

Fatal error: Uncaught exception ‘Doctrine_Connection_Mysql_Exception’ with message ‘SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`ci_doctrine`.`post`, CONSTRAINT `post_companys_id_companys_id` FOREIGN KEY (`companys_id`) REFERENCES `companys` (`id`))’ in C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection.php:1082 Stack trace: #0 C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection\Statement.php(269): Doctrine_Connection->rethrowException(Object(PDOException), Object(Doctrine_Connection_Statement)) #1 C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection.php(1042): Doctrine_Connection_Statement->execute(Array) #2 C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection.php(687): Doctrine_Connection->exec(’INSERT INTO pos…’, Array) #3 C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection\UnitOfWork.p in C:\wamp\www\ci_doctrine\system\application\plugins\doctrine\lib\Doctrine\Connection.php on line 1082

The code:
class Post extends Doctrine_Record {

public function setTableDefinition() {
$this->hasColumn(’content’, ’string’, 65535);
$this->hasColumn(’category_id’, ‘integer’, 4);
$this->hasColumn(’companys_id’, ‘integer’, 4);
}

public function setUp() {
$this->actAs(’Timestampable’);
$this->hasOne(’Category’, array(
‘local’ => ‘category_id’,
‘foreign’ => ‘id’
));
$this->hasOne(’Companys’, array(
‘local’ => ‘companys_id’,
‘foreign’ => ‘id’
));
}

}

class Category extends Doctrine_Record {

public function setTableDefinition() {
$this->hasColumn(’title’, ’string’, 255);
}

public function setUp() {
$this->hasMany(’Post as Posts’, array(
‘local’ => ‘id’,
‘foreign’ => ‘category_id’
));
}
}

class Companys extends Doctrine_Record{
public function setTableDefinition() {
$this->hasColumn(’companyName’, ’string’, 255, array(’unique’ => ‘true’));
$this->hasColumn(’contactPerson’, ’string’, 255);
$this->hasColumn(’contactNumber’, ’string’, 255);
$this->hasColumn(’mobileNumber’, ’string’, 255);
$this->hasColumn(’email’, ’string’, 255, array(’unique’ => ‘true’));
$this->hasColumn(’password’, ’string’, 255);
$this->hasColumn(’category_of’, ’string’, 255);
}

public function setUp() {
$this->setTableName(’companys’);
$this->actAs(’Timestampable’);
$this->hasMutator(’password’, ‘_encrypt_password’);
$this->hasMany(’Post as Posts’, array(
‘local’ => ‘id’,
‘foreign’ => ‘companys_id’
));
}

protected function _encrypt_password($value)
{
$salt = ‘#*seCret!@-*%’;
$this->_set(’password’, md5($salt . $value));
}
}

maybe u have a better idea, i just want to have groups with users, and every user to be part of just one group.

id username group_id
1 user1 1

and in group table:

id name
1 group 1

and after second insert i have in users table:

id username group_id
1 user1 1
1 user2 2

and in group table:

id name
1 group 1
2 group 1 ( – this is the problem, group 1 already exists, why is added again and is not use his id? )

i hope this time my explanation are better

i have a question

let say we have 2 tables:
1. user – [id] [username][password][group_id]
2. group – [id] [name]

if I say user has one group and group has many users – conditions

if i try to do something like here:
$u->username= ‘user1′;
$u->Group->name = “grup1″;
$u->save();
it will insert in table user 1 record and in column group_id value 1.

Problem is if i want to add another user to same group, instead to insert a new line in only table user with value 1 on group_id field, i get inserted a row in user with group_id2 and in group another row with id 2 and same name.

Any help will be apreciated.

Thanks

Your Test model has Categories assigned to forums in the code, but I don’t see the relationships in your diagram. Was there a reason for that?

Just a “quick” question about relationships in doctrine. Ie. if you create table called paper, and it belongs to a category, so i would define hasOne in paper-model, and hasMany in category -table.

I have done that, but when i try to save paper without giving it a category value, it gives me a error. I haven’t defined that category is required value. But is it so, that if you define relationships, the value becomes required?

I also have defined created_by field in paper-model, and it links to user-table. But it should not be required, but it doesnt allow me to save if created_by is not set.
