Ruby Question

find array element

I have an array

@words = Word.find_all_by_lesson_id(params[:id]) - @user.words


and want to find one element by word_id, something like

@current_word = @words[params[:id2].to_i]


where
params[:id2]
is
words.id


Of course it's wrong, because the arrays index is not the same as
words.id
,
so how can I do it correct?

OR

can you advice me on how to work with the model if I want to exclude some records from it?

Answer
@current_word = @words.detect{|w| w.id == params[:id2]}
