I have a simple question. I have a seriaizer that looks like this:
class GroupSerializer < ActiveModel::Serializer
attributes :id, :name, :about, :city
end
The problem is that, whenever I change my model, I have to add/remove attributes from this serializer. I just want to get the whole object by default as in the default rails json respond:
render json: @group
How can I do that?
At least on 0.8.2 of ActiveModelSerializers you can use the following:
class GroupSerializer < ActiveModel::Serializer
def attributes
object.attributes.symbolize_keys
end
end
Be carful with this though as it will add every attribute that your object has attached to it. You probably will want to put in some filtering logic on your serializer to prevent sensitive information from being shown (i.e., encrypted passwords, etc...)
This does not address associations, although with a little digging around you could probably implement something similar.

UPDATE: 01/12/2016
On 0.10.x version of ActiveModelSerializers, attributes receives two arguments by default. I added *args to avoid exception:
class GroupSerializer < ActiveModel::Serializer
def attributes(*args)
object.attributes.symbolize_keys
end
end
