Removing relations is not being audited by audited gem

Question

I'm using Associated Audits on a has_many through relation with Collective Idea's audited gem. I see create audits for the through model being added, but I do not see any audits when that relation is removed.

Here are my 3 models. A Post can be in multiple Categories.

app/models/post.rb

class Post < ActiveRecord::Base
  audited
  has_associated_audits

  has_many :categorizations, dependent: :destroy
  has_many :categories, through: :categorizations
end

app/models/category.rb

class Category < ActiveRecord::Base
  audited
  has_associated_audits

  has_many :categorizations, dependent: :destroy
  has_many :posts, through: :categorizations
end

app/models/categorization.rb

class Categorization < ActiveRecord::Base
  audited
  audited associated_with: :post
  audited associated_with: :category

  belongs_to :category
  belongs_to :post
end

My Post form has a pile of checkboxes for categorization:

<%= f.association :categories, as: :check_boxes, collection: Category.order(:name), label_method: :name, value_method: :id, label: false %>

• When I edit an existing Post and check a box for a Category, I do see a new audit entry with a create value in the audit's action field.
• When I edit an existing Post and uncheck a box for a Category, I do not see a new audit entry.

• I do see destroy audits for both the Post and the Categorization auditable_type fields when I delete a Post, so that aspect works nicely.

  1. Can audited track those deselections? If so, how?
  2. Is there anything obviously bad/wrong about my audited setup in the models above? There's no has_many through documentation to follow, so I guessed a bit.

Answer 1

Potentially related to this Rails issue, I had to swap out my dependent: :destroy lines:

app/models/post.rb

class Post < ActiveRecord::Base
  audited
  has_associated_audits

  has_many :categorizations
  has_many :categories, through: :categorizations, dependent: :destroy
end

app/models/category.rb

class Category < ActiveRecord::Base
  audited
  has_associated_audits

  has_many :categorizations
  has_many :posts, through: :categorizations, dependent: :destroy
end

With this setup in place, I'm seeing audits for both adding and removing relations.
