create post method error

Hi

I am having trouble with a submit code for a form. I don't get errors or anything. it just goes to the redirect and it dosen't show anything

  def create     @comment = ForumComment.new(params[:post])     @comment.user_id = current_user.id        if @comment.save           redirect_to :controller => 'forums', :action => 'index'     end     redirect_to :action => 'create'   end end

the create.rhtml just has this code for error reporting(to help me fix it)

<%= error_messages_for 'forum_comment' %><br/>

is there anything wrong with the create method syntax?

thanks in advaced

You probably meant that second redirect to be a render. Your code would fail if the save actually happened since you would then both render and redirect.

Typically the pattern is

def new   @foo = Foo.new end

def create   @foo = Foo.new(params[:foo])   if @foo.save     redirect_to :controller => 'somewhere'   else     render :action = 'new'   end end

why do you do the @foo=Foo.new twice? I understand the second once, since you are doing the create and using the params to receive it, but isn't the other one not needed?

thanks,

The first one is for the new page, which still needs an instance of foo to render the form (so everything will be blank). You could also set defaults. Fred
