Insert data into a database without user input

Hello there, I am new around here and have been looking over the internet for a solution but can't find one. I am fair new to rails but have a decent understanding of it to get by and a few years experience behind me. My problem is that I try to insert data in a database and it does not come up. The information the user types is inserted however I wish to insert the ID and other stuff the user can not change. This is what I have so far:

The controller:

def create     @postform = new(params[:postform])     @post = Post.new(:title => @postform.title, :body => @postform.body, :user_id => session[:user_id]).save     respond_to do |format|       if @post.save         format.html { redirect_to(@post, :notice => 'Post was successfully created.') }         format.xml { render :xml => @post, :status => :created, :location => @post }       else         format.html { render :action => "new" }         format.xml { render :xml => @post.errors, :status => :unprocessable_entity }       end     end   end
