My guess would be that something is getting loaded twice. I suggest
taking out all the requires and putting them back till you get the
problem. That may help you to home in on it.
Yes, it seems some constant is already initialized.
I tried removing the includes, but they are all needed...

Dear everyone,
I'd like to ask two questions, how can I optimize my performance of my current model?
I'd like to use the information from translations table as it is (all columns) ....
=> Translation(id: integer, word_id: integer, conversion_id: integer, created_at: datetime, updated_at: datetime, user_id: string, unit_id: integer, last_learned: date, missed: integer, learned: integer)
... and merge it to any translations/conversions children of Word.
My model getter self_with_translations should attach it to all translations/conversions but using join.
Second thing would be to optimize the check for in unit_ids section for only select unit_ids once and not have many selects.
The program is right here: http://open-voc.org
I appreciate any help,
kind regards,
Alex
Code below:
class Word < ActiveRecord::Base
has_and_belongs_to_many :conversions, class_name: "Word",
join_table: "translations",
association_foreign_key: "conversion_id"
def available_units=(unit_ids_as_array)
@available_units = unit_ids_as_array
end
def available_units
@available_units || []
end
def with_enriched_data
#@FIXME join merge instead of calling sep.
meta = Translation.where(word_id: self.id).first
# fix for deleted units, don't deliver them!
self.available_units = Unit.all.map{|u| u.id } # @FIXME Cache or call only one time
unit_id = meta.unit_id if self.available_units.include? meta.unit_id
# enrich with attrs unit_id, ..........
attributes.merge(unit_id: unit_id, missed: meta.missed)
end
def self_with_translations(targetlang_id={})
conversions = self.conversions.where(language_id: targetlang_id).map do |c|
c.with_enriched_data
end
attributes.merge(translations: conversions)
end
end
