I have several apps that share common base models which I am coding into
a plugin, but each app may need to add some additional code or override
some code in the plugin model.
One of the main differences is that I use multiple database servers in
alot of these apps, which is managed by the “use_db” plugin. I am
trying to figure out a way to use the “use_db” plugin without hard
coding it into the plugin class. I dont want to have to change the
plugin every time I install it in a new app.
Can anyone think of a way to create a class inside the rails directories
that would be able to extend the plugin model and also be able to
specify my “use_db” database… overriding the default rails database.
I would also need to be able to add new methods and override methods
contained in the plugin model. The model in the plugin contains lots of
associations, named_scopes, etc… so that stuff would still need to be
active in the extended model… so I dont think a module would work.
For those not familiar with “use_db” it just allows you to include a
prefix which is pulled from database.yml, and the model will use this
class Widget < ActiveRecord::Base
use_db :prefix => “slave2_”
this would use the database config “slave2_production” in database.yml
for that model if you are in prod mode.
I have tried using “extends” inside the class, creating a subclass,
etc… but nothing seems to give me the behavior I desire. Any ideas
guys? Thanks in advance!
