<%= nested_form_for(@user) do |f| %>     <% if @user.errors.any? %>         <div id="error_explanation">           <h2><%= pluralize(@user.errors.count, "error") %> prohibited this user from being saved:</h2>

          <ul>             <% @user.errors.full_messages.each do |message| %>                 <li><%= message %></li>             <% end %>           </ul>         </div>     <% end %>

    <div class="field">       <%= f.label :user_name %><br>       <%= f.text_field :user_name %>     </div>     <div class="field">       <%= f.label :email %><br>       <%= f.text_field :email %>     </div>     <div class="field">       <%= f.label :password %></br>       <%= f.password_field :password %>     </div>

    <div class="field">       <%= f.label :password_confirmation %></br>       <%= f.password_field :password_confirmation %>     </div>

    <%= f.fields_for :profiles do |f1| %>         <div class="field">           <%= f1.label :name %><br>           <%= f1.text_field :name %>         </div>         <div class="field">           <%= f1.label :last_name %><br>           <%= f1.text_field :last_name %>         </div>         <div class="field">           <%= f1.label :birthday %><br>           <%= f1.datetime_select :birthday %>         </div>         <div class="field">           <%= f1.label :avatar %>           <%= f1.file_field :avatar %>         </div>     <% end %>     <div class="actions">       <%= f.submit %>     </div> <% end %> And this is my UserController

  def user_params     params.require(:user).permit(:user_name, :email, :password, :password_confirmation, profile_attributes: [:name, :last_name, :avatar, :birthday])   end end

Thnks

Are there any validations on either model? Could you show the model files here?
