Rails - Jun 2005 - Beginner's error with updating

I am getting this error from my articles controller:

wrong number of arguments (1 for 2)

|app/controllers/article_controller.rb:38:in `update''
app/controllers/article_controller.rb:38:in `update''|

The controller for the update action looks like this:
def update()
        @article = Article.update(@params[''article''])    
<<-------- line 38
        if @article.update_attributes(@params[''article''])
            @article.categories.clear
            @article.categories<<@params[''category'']
            flash[''notice''] = ''Article was
successfully updated.''
            redirect_to :action => ''show'', :id =>
@article.id
        else
              flash[''notice''] = ''There was a problem
updating your
article. Please try again.''
              render_action ''edit''
        end
    end

These are parameters being sent back from the form:
*Parameters*: {"article"=>{"body"=>"This is a
test.", "title"=>"Wow, the
4th Article", "author"=>"Danielle Ezell"},
"id"=>"6",
"categories"=>["1", "4"]}

Any ideas? BTW, the articles and categories have a habtm to each other.

I believe you want Article.find(@params[:id]) on line 38.

Thanks Justin! That was exactly what I needed. Sometimes, you stare at 
something for so long that you can''t see it.
