ActiveModelSerializers in rails

Question

I am using active_model_serializers in my app (for API's):

class TrainingModuleSerializer < ActiveModel::Serializer
  attributes :id, :name, :description, :status, :module_type
  has_many :courses, serializer: CourseSerializer
end

class CourseSerializer < ActiveModel::Serializer
  attributes :id, :name
end

def training_module_list
  @training_modules = TrainingModule.where(tenant_id: 1)
  render :json => @training_modules
end

In some API's, I need to add courses data (there is has_many association with training_module), but in some API's I don't want to add courses data.

Can anybody explain how I can do this?

Answer 1

Just create one more serializer without has_many

class SimpleTrainingModuleSerializer < ActiveModel::Serializer
  attributes :id, :name, :description, :status, :module_type
end

and use it in the controller

render json: @record, serializer: SimpleTrainingModuleSerializer
