Update Nested Attributes when updating and id provided
I have a model, Report, that has_many Features and accepts_nested_attrubutes_for features.
Class Report < ApplicationRecord
has_many :features, dependent: :destroy
accepts_nested_attributes_for :features
def features_attributes=(features_attributes)
features_attributes.each do |feature_attributes|
f = Feature.by_id_or_map_linkage(feature_attributes)
if f
f.update_attributes(feature_attributes)
else
f = Feature.create(feature_attributes)
end
self.features << f
end
end
end
I've added a method that checks if the feature already exists. I do this check by map_linkage or id, because they are unique fields on the features table.
This works, but is horrible. This logic should be in the Feature model - nested attributes that include one of the identifying fields should trigger an update, not a create.
How can I do this? It feels like this is probably a simple setting I am not aware of or a simple refactoring to the Feature model that would be easier to maintain and avoid duplication in other controllers that update Features through nested_attributes.
