end

here form:

<%= form_for(@user) |f| %> <% if @user.errors.any? %>     <div id="error_explanation">       <h2><%= pluralize(@user.errors.count, "error") %> prohibited user           being saved:</h2>        <ul>         <% @user.errors.full_messages.each |msg| %>             <li><%= msg %></li>         <% end %>       </ul>     </div> <% end %>  <div class="field">   <%= f.label :username %><br />   <%= f.text_field :username, autofocus: true %> </div>  <div class="field">   <%= f.label :name %><br />   <%= f.text_field :name, autofocus: true %> </div>  <div class="field">   <%= f.label :lastname %><br />   <%= f.text_field :lastname, autofocus: true %> </div>  <div class="field">   <%= f.label :email %><br />   <%= f.email_field :email, autofocus: true %> </div>  <div class="field">   <%= f.label :password %>   <% if @minimum_password_length %>       <em>(<%= @minimum_password_length %> characters minimum)</em>   <% end %><br />   <%= f.password_field :password, autocomplete: "off" %> </div>  <div class="field">   <%= f.label :password_confirmation %><br />   <%= f.password_field :password_confirmation, autocomplete: "off" %> </div> <div class="field">   <%= f.label :role_id %><br />   <%= f.collection_select :role_id, role.all, :id, :name_role_select  %> </div> <div class="actions">   <%= f.submit "sign up", class: 'button' %> </div> 

you aren't using user_params.

instead of in create action:

user.new(params[:user_params]) 

you need this, calls user_params method defined in controller:

user.new(user_params) 

your original way looking params passed in request called 'user_params'(which doesn't exist).

similarly, update action need:

if @user.update_attributes(user_params)   #etc...
