I have an existing table with 5 columns, and I want to generate an Entity without that generates a new migration with new table!
Thanks!
So, as I mentioned in comment - you just need to follow steps in Symfony documentation.
This way, for Symfony 3 you need follow this:
php bin/console doctrine:mapping:import --force AppBundle xml
This command line tool asks Doctrine to introspect the database and generate the XML metadata files under the src/AppBundle/Resources/config/doctrine folder of your bundle.
Once the metadata files are generated, you can ask Doctrine to build related entity classes by executing the following command.
php bin/console doctrine:mapping:convert annotation ./src
It will generate Entity classes, and after that you must to remove the XML files, generated by first command.

Following: https://symfony.com/doc/current/doctrine/reverse_engineering.html
The command: php bin/console doctrine:mapping:import "App\Entity" annotation --path=src/Entity overwrites current Entity/* files, instead of just updating them with new columns from the database.
What is the standard method for updating entities pragmatically from the database without overwriting custom functions / logic in the existing Entity files?
php bin/console make:entity --regenerate
Seems to help in regenerating the entity from the db without overwrite.
I have already a few entities, but now a new table appeared in a database, and I'd like to generate an entity on only this one table.
I already saw this, but I have further questions.
I already have a User entity (and a db table). Now, the new table is called "Report" (no entity for it right now, I want to create it) and it has a foreign key to User. There are also a few more foreign keys.
If I do what is suggested in the above answer, that is:
$ php app/console doctrine:mapping:import --force AppBundle xml --filter="Report"
$ php app/console doctrine:mapping:convert annotation ./src/AppBundle/Entity --from-database --filter="Report"
$ php app/console doctrine:generate:entities AppBundle:Report --no-backup
Will Doctrine generator try to modify my User entity? Or will just create a Report entity?
Btw. I understand(?), this it will not, because this is ManyToOne relation, but let's assume for a moment that this is ManyToMany for a moment.
I know I could simply try it, but the last time I executed the doctrine:mapping:import --force command I ended up with a crashing app and I spent many hours to solve this problem, until someone on Stackoverflow told me to remove the src\AppBundle/Resources/config/doctrine/ directory, which helped.
I didn't think about making a backup before running this command.
So, I'm a bit afraid of it... Now I created a backup, but I'm not sure if this will help in case of troubles.
It depends on the /Resources/config/doctrine directory. If you empty it out and do the commands you described, then only the Report entity will be modified. If you have all of the previous mappings in that directory it should modify the User entity as well.
The commands will automatically create backups of your entities for you, so you will have a new User.php and a backup in User.php~, which you should be careful of if you are using version control and like to git add src/ without thinking too hard about it. You don't want to add those files to source control.
Either way, backups are created, and you should be using version control on top of that, so you should be fine.
This is my first time using symfony framework. I am trying to learn Doctrine. I have created and entity class. I have created an entity called Product. But since there was something wrong I deleted the Entity folder and now I am trying to create one again. But the framework is not allowing me to do so. It saying that an entity class already exists. How do I remove my previous entity class?
You must to clear doctrine cache:
php app/console doctrine:cache:clear-metadata
php app/console doctrine:cache:clear-query
php app/console doctrine:cache:clear-result
Chen creating your Product entity, what type of mapping do you pick ? XML, YAML, Annotation ?
If you pick XML or YAML, then you got an external file that define your mapping, maybe it's this file that is blocking you.
Take a look to src/Path/To/Your/Bundle/Resources/config/doctrine.
Its symfony 2 - doctrine issue.
I was trying to add some more fields to one of my tables in MySQL. After modification, i had run the command doctrine mapping import and doctrine generate entities commands, but the Entity_name.php file under Bundle/Entity/ folder not getting updated. Can anyone help me ?
Thanks and regards,

Your message is brief, but my interpretation is that you are trying to ADD more fields to an existing table, by creating a NEW entity. This doesn't sound like the correct workflow. The entity ought to already exist, and to add fields to the table, will require adding new properties, correctly annotated, to the existing Entity.
What commands are you running, and what command line output are you seeing? The doctrine based SF2 commands offer reasonable information upon failure.
Try to run this command:
$ php app/console doctrine:schema:update --force
I've been doing searches on scaffolding in Symfony 2 and keep finding references to "generators" but so far have not been able to get scaffolding up and working.
By "scaffolding" I'm referring to a way to point your tool at a database and have it generate views/forms to perform CRUD operations.
This can be useful for quickly prototyping something, and/or build a rough admin tool for some of your database tables.
It can also provide a starting point for some form you are building.
Is this possible in Symfony2?
Crud operations are provided by the SensioGeneratorBundle which is included in the symfony standard distribution.
You can use the following command to generate form, templates & controller for existing entitites. It is interactive and can also update your routing automatically.
app/console generate:doctrine:crud
entity classes themselfes can be created with another command - interactive aswell.
app/console generate:doctrine:entity
Generating entities from database is done with:
app/console doctrine:mapping:convert xml ./src/Acme/BlogBundle/Resources/config/doctrine/metadata/orm --from-database --force
which will create xml mapping files. Afterwards you can generate entities as follows:
app/console doctrine:mapping:import AcmeBlogBundle annotation
app/console doctrine:generate:entities AcmeBlogBundle
This would generate the entities with annotations. yml and xml are supported aswell!
You can generate entities from an existing database like this
Then you can generate CRUD forms for those entities like this
There is no native way to create scaffolding directly from the DB. You have to go through this two step process.
