hi all when i m trying to save my tags.this error s cmng........cn anybody help me to how to save the array

error depicting = undefined method `save' for :Array

it would be better if you showed some code about how this array gets created and used...

generally - and assuming the array contains un-saved ActiceRecord Objects and not just params or something:

@tags.map! {|t| t.save }

3

actually i m gettng this error while using act as taggable on steriods plugin

4

def create @article = Article.new(params[:article]) @article=Article.find_tagged_with(params[:tag_list]) @article.save

5

okay now it's clear...

Article.find_tagged_with(params[:tag_list]) will return an array of article objects (even if there is just one match in the database) Then you call save on this array. Which of course will not work.

You are also overriding the new created @article with the ones retrieved from the DB ... why? or is this a typo and the articles you get from the DB should be @articleS ? Like, create a new article, and find related ones by tag to show them after the new article was created?!?

def create   @article = Article.new(params[:article])   @related_articles= Article.find_tagged_with(params[:tag_list])   @article.save end

That should work, if you want that.
