feature request: conditional statements in api template

[atwoodjw]

it would be really handy to conditionally add attributes to an api template.

class User < ActiveRecord::Base

    acts_as_api

    api_accessible :user_show do |t|
        t.add :first_name
        t.add :last_name
        t.add :age

        t.add :favorite_beer if age > 21
    end
end

this is a contrived example, but i do have a (legacy) class that has many, many one-to-many relationships. it would be helpful to conditionally include certain attributes based on the value of another.

cheers!

Hi,
this seems to be a neat idea.

I would want to check for these attributes at rendering time. So I propose to do it the same way activerecord validations and callbacks work, e.g.:

t.add :favorite_beer, :if => lambda{|u| user.age > 21 }

and

t.add :favorite_beer, :if => :is_adult?

to call a method of the model instance.

What do you think?

that sounds terrific -- very straight-forward. i like it.

Hey,
I just released acts_as_api 0.3.3 which adds support for the :if and :unless options.
