How to avoid call_back execution on deep cloned object?

[fchampreux]

Hi, My application manages business rules, and nested tasks. During a normal creation process, some attributes are initialised in a call-back, such as before_create :set_hierarchy, for eacf object (rule & tasks). For managing versions of a business rule, I deep_clone it. In this case, the before_create call-back must not be executed, so my code is:

BusinessRule.without_callback(:create, :before, :set_hierarchy) do
    @business_rule_version = @business_rule.deep_clone include: :tasks 
    # some stuff
end

This works fine for the business rule, but how can I specify this without_callback clause for the nested tasks? Thanks!

Hi,

Actually deep_cloneable has not much to do with the creation process, it just builds the hierarchy in memory and lets AR do its thing when you call save. Can't you just do the same as you do for the business rule? Like this:

BusinessRule.without_callback(:create, :before, :set_hierarchy) do
  Task.without_callback(:create, :before, :set_hierarchy) do
    @business_rule_version = @business_rule.deep_clone include: :tasks 
    @business_rule_version.save!
  end
end
