Rails errors not showing?

So im learning rails, and following the rails getting started guide (I've actually done the "blog app" on the Udemy rails course, but im making sure I can write it from scratch first before moving on).

Anyways, i've gotten Delete/Create running, but I was adding validation...and while the validation works my errors aren't showing up.

Right now my pages are super simple:

new.html.erb

<% 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 |msg| %>
        <li><%= msg %></li>
      <% end %>
    </ul>
  </div>
<% end %>

<%= form_with scope: :user, url: users_path, local: true do |form| %>
<p>
  <%= form.label :username %><br>
  <%= form.text_field :username %>
</p>
<p>
  <%= form.label :name %><br>
  <%= form.text_field :name %>
</p>
<p>
  <%= form.label :age %><br>
  <%= form.number_field :age %>
</p>
<p><%= form.submit %></p>
<% end %>

users_controller

class UsersController < ApplicationController
    def index
      @users = User.all
    end

    def new
      @user = User.new
    end

    def edit
      @user = User.find(params[:id])
    end

    def create
      @user = User.new(params.require(:user).permit(:username,:name,:age))
      if @user.save
        redirect_to users_path
      else
        render 'new'
      end
    end

    def update

    end

    def destroy
      @user = User.find(params[:id])
      @user.destroy
      redirect_to users_path
    end

end

So the weird thing if I go into my network tab in dev tools I can see this show up in the response tab:

  <div id="error_explanation">
    <h2>
      1 error prohibited this user from being saved
    </h2>
    <ul>
        <li>Username has already been taken</li>
    </ul>
  </div>

But it doesn't show up in "elements" in Chrome dev tools. I've restarted rails....so Im really not sure why the elements are not showing up. I DO have bootstrap 4.00 beta installed, but not sure why that would matter. This is rails 5.1.4 btw.

This is because you are not getting the same @user in the <% if @user.errors.any? %>

Try this :

<%= form_with scope: :user, url: users_path, local: true do |form| %>
  <% 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 |msg| %>
          <li><%= msg %></li>
        <% end %>
      </ul>
    </div>
  <% end %>

<p>
  <%= form.label :username %><br>
  <%= form.text_field :username %>
</p>
<p>
  <%= form.label :name %><br>
  <%= form.text_field :name %>
</p>
<p>
  <%= form.label :age %><br>
  <%= form.number_field :age %>
</p>
<p><%= form.submit %></p>
<% end %>
