Rails: form_for doesn't turn parameters

Question

I'm basically trying to create a Rails form_for but it simply does not turn parameters. I've checked the server log and it receives the parameter but cannot capture on the create function. I'm watching andrewperk's tutorial (http://www.youtube.com/watch?v=unq1yubL6lQ) about create and save methods. What could I possible done wrong?. Here is my Users controller;

 def new
    @user=User.new
  end
  def create
    @user=User.new(params[:user])
    if @user.blank?
      render :new
    else
      @user.save
      render :index
    end
  end

And here is my form;

<h1>Add an available user</h1>

    <%= form_for @user do |a| %>
        <p>
            <%= a.label :name %>
            <%= a.text_field :name %>
        </p>
        <p>
            <%= a.label :surname %>
            <%= a.text_field :surname %>
        </p>
        <p>
            <%= a.submit "Add new available user"%>
        </p>
    <% end %>

params[:user] is correct

You should use params[:user] in your controller, because this is how the HTML form fields are named by default (you can check page source).

Also I'd suggest refactoring the create method a bit. It is a convention that you redirect to index page instead of just rendering it after creating a record.

def create
  @user = User.new(params[:user])
  if @user.save
    redirect_to users_path
  else
    render :new
  end
end

I'm sorry I have mistyped. I already have the user as params[:user]

You could, if you wanted to be super-fancy, use "respond_with" to clean this up even more :)
