Symfony entities are not updated in database after changes - symfony

Question

My symfony app is using Doctrine to persist entities in mysql.
Today I updated my entities "Advertiser" and "Report" so there are relations between the two - as suggested in this post: When using EntityType to show a select, can't save entity from Symfony form
When I try creating a migration, it says that the database is already in sync.
php bin/console make:migration
Returns:
[WARNING] No database changes were detected.
The database schema and the application mapping information are already in sync.
However if I look at the table for the report, I see it still has the old schema:
+---------------+------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+---------------+------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| advertiser_id | int(11) | NO | MUL | NULL | |
| start_date | date | NO | | NULL | |
| end_date | date | NO | | NULL | |
| deleted | tinyint(1) | NO | | NULL | |
+---------------+------------+------+-----+---------+----------------+
Even though my entity looks like this now:
class Report
{
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="date")
*/
private $start_date;
/**
* #ORM\Column(type="date")
*/
private $end_date;
/**
* #ORM\Column(type="boolean")
*/
private $deleted;
/**
* #ORM\ManyToOne(targetEntity="App\Entity\Advertiser", inversedBy="reports")
* #ORM\JoinColumn(nullable=false)
*/
private $advertiser;
public function getId(): ?int
{
return $this->id;
}
public function getStartDate(): ?\DateTimeInterface
{
return $this->start_date;
}
public function setStartDate(\DateTimeInterface $start_date): self
{
$this->start_date = $start_date;
return $this;
}
public function getEndDate(): ?\DateTimeInterface
{
return $this->end_date;
}
public function setEndDate(\DateTimeInterface $end_date): self
{
$this->end_date = $end_date;
return $this;
}
public function getDeleted(): ?bool
{
return $this->deleted;
}
public function setDeleted(bool $deleted): self
{
$this->deleted = $deleted;
return $this;
}
public function getAdvertiser(): ?Advertiser
{
return $this->advertiser;
}
public function setAdvertiser(?Advertiser $advertiser): self
{
$this->advertiser = $advertiser;
return $this;
}
}
I've been searching for solutions and have tried these, but no luck:
php bin/console doctrine:cache:clear-metadata
php bin/console doctrine:schema:update --force
Please let me know if you have any suggestion on how I can update my database with my updated schema.

Answer 1

I had the same issue, try clearing the cache with:
symfony console cache:clear

Answer 2

As a many to one relation, it's normal that you're database advertiser column only stores the key of the report as a "link" to it, so that's why Symfony doesn't see any changes in your DB.
Maybe you can also use :
php bin/console doctrine:schema:update --dump-sql
to see changes in your DB
php bin/console doctrine:schema:update --force
to apply changes without using migrations

Answer 3

Maybe it's useful for someone, but when using annotations make sure that the comment block follows the DocBlock format, the first line should have two asterisks: /** and not a single asterisk /*
DocBlock
/**
*
*/
PHP Multiline comment
/*
*
*
*/

Answer 4

Try using proper annotation setup may be missing required configuration, you can always try to validate your schema with bin/console doctrine:schema:validate:
/**
* #ManyToOne(targetEntity="App\Entity\Advertiser", inversedBy="reports")
* #JoinColumn(name="advertiser_id", referencedColumnName="id")
*/
private $advertiser;
And check Advertiser entity for issues as well, maybe it is missing primary key or something.

Answer 5

I believe that the problem was that I previously had a property called "advertiser_id" (int) on the report object. And possibly I was trying to change too many things at once for doctrine to manage. Previously, I had tried to remove the advertiser_id while adding the relation property for advertiser.
To get doctrine working again, I removed the advertiser property from the Report object - along with the getters and setters. I also removed the reverse lookup stuff from the Advertiser object. When I tried to run the migration, it seems like there were several migrations that it was trying to run - all doing the same thing: dropping a foreign key that doesn't exist. So I commented out all of those commands in the migration files and finally was able to get it to migrate. I also removed the advertiser_id property. The app is working again.
Then I tried adding the "advertiser" relation property back to the report. This time it worked as expected and I was able to migrate. So I think the issue is related to my object already having an advertiser_id property. Now that I've added the advertiser relation to the Report object, I see that doctrine added an advertiser_id column to the table. I suspect that it being present previously was the reason things broke down.
Thanks for the replies! Glad to have it working again.
