Doctrine 1.2: How do i prevent a contraint from being assigned to both sides of a One-to-many relati
- by prodigitalson
Is there a way to prevent Doctrine from assigning a contraint on both sides of a one-to-one relationship? Ive tried moving the definition from one side to the other and using owning side but it still places a constraint on both tables. when I only want the parent table to have a constraint - ie. its possible for the parent to not have an associated child.
For example iwant the following sql schema essentially:
CREATE TABLE `parent_table` (
`child_id` varchar(50) NOT NULL,
`id` integer UNSIGNED NOT NULL auto_increment,
PRIMARY KEY (`id`)
);
CREATE TABLE `child_table` (
`id` integer UNSIGNED NOT NULL auto_increment,
`child_id` varchar(50) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY (`child_id`),
CONSTRAINT `parent_table_child_id_FK_child_table_child_id`
FOREIGN KEY (`child_id`)
REFERENCES `parent_table` (`child_id`)
);
However im getting something like this:
CREATE TABLE `parent_table` (
`child_id` varchar(50) NOT NULL,
`id` integer UNSIGNED NOT NULL auto_increment,
PRIMARY KEY (`id`),
CONSTRAINT `child_table_child_id_FK_parent_table_child_id`
FOREIGN KEY (`child_id`)
REFERENCES `child_table` (`child_id`)
);
CREATE TABLE `child_table` (
`id` integer UNSIGNED NOT NULL auto_increment,
`child_id` varchar(50) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY (`child_id`),
CONSTRAINT `parent_table_child_id_FK_child_table_child_id`
FOREIGN KEY (`child_id`)
REFERENCES `parent_table` (`child_id`)
);
I could just remove the constraint manually or modify my accessors to return/set a single entity in the collection (using a one-to-many) but it seems like there should built in way to handle this.
Also im using Symfony 1.4.4 (pear installtion ATM) - in case its an sfDoctrinePlugin issue and not necessarily Doctrine itself.
