I am trying to have a login form in my rails applicaiton but getting an error like

```
NameError in AuthController#login
uninitialized constant AuthController::User

```

Here is my view

```
<%= form_for @users, do |f| %>
    <%= f.text_field :name, placeholder: 'Username' %>
<%= end %>

```

My controller is

```
def login
    #@users = User.all I 
  end

```
