问题
Is there a convention for naming tables when using Doctrine ORM? I like to name tables with the plural but if there's a convention I want to stick to it.
So the table 'users' would be related to tables using the fk as the singular ('user_id').
Is there a best practice for this (using singular or plural table names) and if the latter, how does this apply to tables where the plural isn't a simple case of adding an 's'.
For example I currently have a table called 'categorys' instead of 'categories' to maintain the convention of adding 's'.
Is this a sensible approach?
回答1:
I used to use plural table names when using my own basic ORM but I switched over to singular table names when I started using symfony + Propel and now a little bit of Doctrine. The reason for this is for the class names because you want to create a User and not a Users.
With Doctrine, when it comes to collections or relations, you tell it what the alias should be:
http://www.doctrine-project.org/projects/orm/1.2/docs/manual/working-with-models/en
You'll see the a User can have many Phonenumber so a foreignAlias was setup in the YAML schema so it would be Phonenumbers effectively accessed via $user->Phonenumbers.
In your example you'll set the foreignAlias to be Categories while keeping the table and record named Category.

The Doctrine convention is to use singular names for tables and models, as the first answerer explains, because logically you want methods like:
$user->Phonenumbers
... instead of:
$user->Phonenumberss
The definitions can be customised through Aliases.
