Hi,
I just had the idea, that it should be possible to do something like that:
ruby script/generate relation Item has_and_belongs_to_many Tags
This would do following things:
- Create a migration with the table needed for the m:n relation. For other relations it would add a migration that adds the needed foreign keys to the db schema (i.e. Post has_many Comments would lead to a migration that adds the field post_id(int) to the comments table).
- Automagically insert the :has_and_belongs_to_many statement into the models as needed (other relation types would obviously lead to different stamtements, i.e. for 1:n relations).
- Perhabs there should be a script that tears down relations (deleting the columns from the tables and the relation statements in the models).
- Do other things that I have not though of.
What do you think about this? Please feel free to discuss this (here?)!
Greetings,
Robo
