Default Serializer Rendering Options in Rails Controller

I am using Active Serializers in a rails project and has an object user

that needs to be passed from controller to serializer:

# Note the 'user:' option that will be accessible inside
# the serializer with @options[:user]
def show
render json: @some_object, user: current_user
end

def index
render json: SomeObject.all, user: current_user
end

It's good enough for what I'm trying to do, but it's not very DRY and results in statements render

that are littered with options. When these parameters change, I need to go back and manually delete / change them in all activities.

My question is: Is there a way to set a default parameter list to be called render

at the controller level instead of manually entering parameters into each action of one controller?

This can be done by adding this method to the controller:

def default_serializer_options  
  {user: current_user}  
end


Then you can access it from the serializer via options[:user]
