Symfony: Rebuild from Schema.yml Without Loss of Data

As my test database became more complex, I hated entering data again after doing a propel-build-all. Following these commands, you can save your database content after rebuilding your database from your schema file.

After changing the schema.yml file, the user typically uses propel to rebuild. One of the unfortunate side effects of this is loss of data in the database.

Following these commands will dump the database, rebuild from the new schema.yml file, and then reload the content.

Note: I would trust this on test data. Consider additional backup measures before using this on a real database.

frontend is my application name here. dump.yml can be named whatever yml is desired.

php symfony propel-dump-data frontend dump.yml
php symfony cc
php symfony propel-build-all-load frontend


In order, this does the following:

- This dumps the database associated with the frontend app.
- Clears the symfony cache
- Then does a build-all and reloads the database.

Enjoy more coding and less test data generating.
