Generating a Single Entity from Existing Database Using Symfony2 and Doctrine

Generating a single Entity from existing database using symfony2 and doctrine

I had the same problem, you've to do this way:

php app/console doctrine:mapping:convert metadata_format \
./src/App/MyBundle/Resources/config/doctrine \
--from-database \
--filter="Yourtablename"

Then

php app/console doctrine:mapping:import AppMyBundle \
metadata_format --filter="Yourtablename"

Where metadata_format is the file ending you want to generate (e.g. xml, yml, annotation)

And finally

php app/console doctrine:generate:entities AppMyBundle --no-backup

Like this doctrine will load only the entity you need. Just be carefull on the filter you must use the CamelCase !

Hope this will help you

Generate single Symfony2 entity from an existing table

After finding that the --filter does not do what I hoped, I scripted tbl_remote and created it in my test database. I then changed parameters.yml to look at the test database and after running: php app/console doctrine:mapping:import --filter="tbl_remote" AppBundle
i was greeted with: "Database does not have any mapping information."

This is not my day so I just ran: php app/console doctrine:mapping:import AppBundle and removed the .orm.xml that I did not need.

I was then able to run: php app/console doctrine:generate:entities AppBundle
to generate the single entity!! Not what I wanted but not a complete loss.

Symfony 4, a way for generate Entities from an Existing Database?

You can use

php bin/console doctrine:mapping:convert --from-database annotation ./src/Entity

which should create the entities based on the database setting. Don’t forget to add the namespaces, and you will still need to add the getters and setters, but the bulk of the properties, including annotations and some of the relationships are already included. (Source)

Please also note, that Doctrine will not support this anymore in the next Doctrine version. As written in the Symfony docs

Moreover, this feature to generate entities from existing databases will be completely removed in the next Doctrine version.

SYMFONY 6 - DOCTRINE : mapping and import only some table from an existing databse

There is a --filer= option in doctrine:mapping:import but I think it's not what you're looking for.

If you migrate your codebase to symfony and doctrine and doctrineORM wasn't used before - it would be much easier just to start over and do all by your self. Yes, it's tedious, especially with a huge database, but you will end up with much "cleaner" entities and during this phase you could decide which tables to ignore.

But if you still want try to "import" somehow, consider following steps:

  1. In your local developer environment, create a copy of your database. Just the schema without data. So you have all tables, but they're empty (how to with mysqldump Don't forget to use --no-data)
  2. drop all other tables which you don't want
  3. rename some, if you think, their names wouldn't fit to doctrine's naming convention.
  4. switch to that copy-database in your .env (change db name in DATABASE_URL)

Now try to import again with doctrine:mapping:import. You may need to adjust some tables by repeating step 2) and 3) and then try to import again.

If import succeed, and you have a bunch of entities, now comes the boring and tedious part. You have to manually check all classes in src/Entity.

Depending on your Database (mysql, postgreSQL, sqlite, etc) not all column-types will be exact what you want.

Furthermore, most many-to-one/one-to-many relations and all many-to-many junction tables will be probably converted to standalone Entities like src\CategoryToProduct.php - which isn't right. So you have to delete them and recreate your relations by hand
