Rails - Jul 2008 - How to get a users screen name into a hidden field in a PostsController action?

Instead of the user entering a name, I want to pass their screen name
along with supplied :title and :content fields.  here is what I''ve
got..

f.hidden_field :author, user.screen_name

here is the create method from Posts controller:

  def create
    @title = "Gravity"
    @user = User.find(params[:id]) # this does not work, and I don''t
know why
    if request.post? and params[:post]
      if new
        flash[:notice] = "Comment created"
        redirect_to :action => "index"
      else
        flash[:notice] = "Please complete all fields"
        redirect_to :action => "create"
      end
    end
  end

Please help.

I would need more information but I''ll try to guess, and since you are 
using f.hidden_field you should have a form declaration related to a 
particular object (let''s say "comment"). In that case your
author
information should be accessible through params[:comment][:author] in 
your controller.

That means you should change the line
@user = User.find(params[:id])
in
@user = User.find_by_screen_name(params[:comment][:author])

Don''t forget to change :comment by the good name. If not, then give us 
more information.

What does the html generated from your hidden_field look like?  Is
user.screen_name getting copied over properly? 

If it *is*, you should expect to find it in params[:author] in your
create method I think.

Also, you don''t seem to be saving anything to the db in that method--I
would expect to see something like:

  @post = Post.new(params[:post])
  @post.save

In there somewhere.

Really simple if you''re using the RESTful_Authentication plugin (you
really should if you''re not)

f.hidden_field :author, current_user.login
