class Project include Mongoid::Document has_and_belongs_to_many :users field :name, type: String after_create :create_callback after_update :update_callback def create_callback Project.skip_callback(:update, :after, :update_callback) puts "Create callback called" Project.set_callback(:update, :after, :update_callback) end def update_callback puts "Update callback called" end end
Here is the controller:
project = Project.new(name: "Project1") puts "new project" if project.valid? project.users << current_user puts "added authenticated user" project.save! puts "saved project" end
This is the output:
new project
added authenticated user
Create callback called
Update callback called
saved project
There are two of oddities I'm seeing:
- Append one or many tags, saving them if the person is persisted.
person.tags << Tag.new
So, in my code I appended the authenticated user to a newly (not-persisted) project. I expected the project to call the after_create callback after project.save!, but it seems like it is called after I append the user. This seems contrary to what the docs say, since the project was not persisted and so the appending the user should not fire the after_create callback?
- The after_update callback is being called immediately after the after_create callback. Is this expected behavior?
