no object in Resource

[zoran]

in a more complex scenario I want to access attributes of the @object in a Resource (just like in a Serializer). Is that possible somehow?

class UserResource
  type :users
  
  has_many :addresses,
    resource: AdressResource,
    foreign_key: :abc,
    primary_key: :xyz,
    scope -> { Adress.where("zip LIKE ?", @object.zip) }
end

@zoran I think this is probably best left to the lower-level DSL, which you can customize with a block. We wouldn't be dealing with @object at this point but @objects (because you could be hitting an index endpoint listing all users, then want all addresses for all users). That's available in the lower-level DSL:

class UserResource
  type :users
  
  has_many :addresses, options do
    scope do |users|
      Address.where(["zip LIKE ?", users.map(&:zip))
    end
  end
end

Does that work for you? Note this will override any scope option you pass to has_many.

mhh, I get missing keywords: scope and I have to use an empty scope option:

has_many :addresses,
  scope: -> {} do
    scope do |users|
      Address.where(["zip LIKE ?", users.map(&:zip))
    end
  end

Yeah, I should definitely make it so you can pass EITHER scope key, OR a scope block. primary_key/foreign_key would still be used to assign the objects to each other, though.

After that I'd say the abstraction still looks correct to me. Would just making scope optional sound good to you?

[zoran]

Yes that would be great

@zoran this is in master, I will release a new version tonight

Fixed in 0.5.5
