enumerate_authors(initial_id = 0) click to toggle source

Incrementally (re-)assigns the id of every associated author (Person) This is only really useful if you assume every author is unique.

# File lib/models/ref_collection.rb, line 36
def enumerate_authors(initial_id = 0)
  i = initial_id 
  collection.each do |r|
    r.authors.each do |a|
      a.id = i
      i += 1
    end
  end
end

# File lib/models/ref_collection.rb, line 72
def unique_author_strings

    end
  end

end

unique_authors() click to toggle source

Returns Array of Taxonifi::Model::Person Will need better indexing on big lists?

# File lib/models/ref_collection.rb, line 84
def unique_authors
  auths = []
  collection.each do |r|
    r.authors.each do |a|
      found = false
      auths.each do |x|
        if a.identical?(x)
          found = true 
          next

      end
      if not found

# File lib/models/ref_collection.rb, line 48
def uniquify_authors(initial_id = 0)
  auth_index = {}
  unique_authors.each_with_index do |a, i|
    a.id = i + initial_id
    auth_index.merge!(a.compact_string => a)
  end
  
  collection.each do |r|
    new_authors = []
    r.authors.inject(new_authors){|ary, a| ary.push(auth_index[a.compact_string])}
    r.authors = new_authors
  end
  true
