Database overview

ORM Directory

The Orm directory contains two folders: Propel and Zed.

The src/Orm/Propel folder is for the following:

• Configuration in Propel format (generated propel.json—don’t touch it).
• Copy of merged schema files (don’t touch).
• Migration files (can be in .gitignore or can be committed; the decision is made on the project level. We recommend using .gitignore; however Propel documentation says that “On a project using version control, it is important to commit the migration classes to the code repository. That way, other developers checking out the project just have to run the same migrations to get a database in a similar state”.

The src/Orm/Zed folder is for the following:

• Entities and the query are objects which can be adopted in projects. They inherit from the same core-level files. This way, we can release methods like preSave() as well as allow adopting them on the project level.
• There are also Base and Map files that are propel-internals (don’t touch them).
