Extend model generator to create association declarations
Reported by CancelProfileIsBroken | November 2nd, 2008 @ 05:51 PM | in 2.x
In Rails 2.2, if you include a belongs_to or references column in a call to the model generator, it will automatically add the belongs_to declaration to the model, as well as creating the foreign key column in the migration.
This patch extends the generator to pass has_many, has_one, and has_and_belongs_to_many "pseudo-attributes" through to the model, creating the appropriate association declarations without adding columns to the migrations or fixtures.
Sample usage:
script/generate model Supplier name:string products:has_many
script/generate model User name:string account:has_one
script/generate model Product name:string parts:has_and_belongs_to_many

This is a good idea, and something I have done with my own extensions in the past. Getting the syntax right is tricky though, as some things could be chained, e.g.:
script/generate model Suppler name:string:vp:vu products:has_many
Or
script/generate model Suppler name:string:validates_presence:validates_uniqueness products:has_many
Could each generate:
class Supplier < ActiveRecord::Base validates_presence_of :name validates_uniqueness_of :name has_many :products end
The first syntax is quite opaque, and the second almost as verbose as the actual declarations in the class. I prefer the first... but there might be a better way.
This of course becomes more powerful when the unit tests are generated also, correctly testing the additional behaviour (slightly OT but the type of syntax in http://github.com/edspencer/rspe... would lend itself well to this situation)

Not sure if this is a right fit or not. Let's have a plugin first.
