Have posted to StackOverflow, but been less than successful there with Mongoid questions ...
I have something very odd going on with a (seemingly) fairly simple relationship - children are duplicated when validation fails on them - I have tried every combination of parameters and variations I can and am now out of ideas
Using Rails 4 and Mongoid 4 from master
For some odd reason I am getting duplicated child records when a record fails validation (but not when it is valid) the form that then renders back to the user has the extra records in it
I have a Pipeline, which has many PipelineStages
Editing a Stage name to blank (which will fail validation) duplicates all the Pipeline.pipeline_stages
ruby class Pipeline include Mongoid::Document has_many :pipeline_stages, dependent: :destroy accepts_nested_attributes_for :pipeline_stages, allow_destroy: true end class PipelineStage include Mongoid::Document belongs_to :pipeline validates :name, presence: true, length: { maximum:50 } end
So when passed into the controller, what appear to be perfectly valid params don't work when update_attributes is used
