doctrine 2.0 : use SQL timestamp - mysql

Question

I'm looking for a way to make doctrine using TIMESTAMP instead of DATETIME for MySql.
Additionaly I need to set ON UPDATE CURRENT_TIMESTAMP and CURRENT_TIMESTAMP as default values.
I would like to have the possibility to have all this code in PHP annotations to have everything in one central place.
How can I do that?

Answer 1

After hours of searching, I found the answer and I hope this helps anyone else looking for a more satisfactory solution than entity lifecycles and the WRONG column type (because a TIMESTAMP is a particular type with specific behaviours beyond just storing a datetime value)
All you need to do is to add
* #ORM\Column(type="datetime", nullable=false)
* #ORM\Version
to your annotation and Doctrine will both create a TIMESTAMP column with DEFAULT CURRENT_TIMESTAMP and then return the actual table value as a valid \DateTime object.

Answer 2

There is no such thing like using TIMESTAMP in mysql with Doctrine.
However, I fixed it myself but have to test it:
Create a file: Doctrine\DBAL\Types\TimestampType.php
Copy the code from TimeType.php into TimestampType.php
Rename 'Time' to 'Timestamp' in the code
Create a new constant, and add timestamp to the typesmap in: Doctrine\DBAL\Types\Type.php
Create function called getTimestampTypeDeclarationSQL in Doctrine\DBAL\Platforms\AbstractPlatform.php
And in that function, return TIMESTAMP
I've used yaml to create my Entities and Proxies, so use in yaml:
type: timestamp
I'm going to test this 'fix'/'workaround' now. I'll let you know.

Answer 3

As suggested by Daniel Criconet,
#ORM\Column(type="datetime", columnDefinition="TIMESTAMP DEFAULT CURRENT_TIMESTAMP")
will make that particular column in the corresponding MySQL table become TIMESTAMP instead of DATETIME.
For YAML version, see the original answer.

Answer 4

/**
* #var \DateTime
* #ORM\Column(type="datetime", columnDefinition="timestamp default current_timestamp")
*/
protected $createdAt;
/**
* #var \DateTime
* #ORM\Column(type="datetime", columnDefinition="timestamp default current_timestamp on update current_timestamp")
*/
protected $updatedAt;

#Polichism provided the right logic, but the patch wasn't accepted. Instead, users were directed to add a custom type. I've implemented that by combining:
The logic in #Polichism's patch
Doctrine's recommended Custom Mapping Types code
Zf2 Application Configuration instructions found here
The final versions can be found on GitHub:
Timestamp Class
See the 'doctrine' part of the Configuration

Answer 6

/** #ORM\Column(type="datetime", nullable=false ) */
protected $created;
this will create timestamp and return datetime object
public function __construct()
{
$this->created = new \DateTime();
}

Answer 7

/**
* #Column(type="datetime", options={"default": 0})
* #version=true
*/
private $data;
create sql like this:
data TIMESTAMP DEFAULT CURRENT_TIMESTAMP NOT NULL
tested on version 2.5.4

Answer 8

#ORM\Version works only for one property per entity so it is not an option if you need to have more than one timestamp field in a table.
