Trying to look through an array and see if a particular value is set and if it is, update the numbers attached to it.

Trying to look through an array and see if a particular value is set and if it is, update the numbers attached to it.

Example:

test = [['test',1,2],['watch',1,2],['fish',1,2]]

So I'd like to search this array for 'test' - if it exists, amend the values 开发者_Go百科'1,2', if it doesn't exist, just add the new search term into the array.

New to ruby and having trouble searching inside a multi-dimensional array and getting the key back


I'd go for the hash method suggested in the comments, but if you're really wanting to store your data in the multidimensional array like that I suppose you could do something like:

search_term = "test"
search_item= nil
test.each do |item|
  if item.include? search_term
    search_item = item
  end
end

if search_item.nil?
  test << [search_term]
else
  search_item << [1,2]
end

I think that would do it (although I'm a little fuzzy on what you were wanting to do after you found the item).
