Tired of writing stuff like this?
accepts_nested_attributes_for :photo,
:allow_destroy => true,
:reject_if => proc { |attrs| reject = %w(title picture).all?{|a| attrs[a].blank?} }
:allow_destroy => true,
:reject_if => proc { |attrs| reject = %w(title picture).all?{|a| attrs[a].blank?} }
Throw this snippet into init.rb into a new plugin folder (I called it reject_if_missing).
module RejectIfMissing
def missing_attrs?(*required_attrs)
Proc.new { |attrs| required_attrs.all?{|a| attrs[a].blank?} }
end
end
ActiveRecord::Base.send(:extend, RejectIfMissing)
def missing_attrs?(*required_attrs)
Proc.new { |attrs| required_attrs.all?{|a| attrs[a].blank?} }
end
end
ActiveRecord::Base.send(:extend, RejectIfMissing)
Now you can do this instead.
accepts_nested_attributes_for :photo,
:allow_destroy => true,
:reject_if => missing_attrs?('title', 'picture')
:allow_destroy => true,
:reject_if => missing_attrs?('title', 'picture')
