Redis – How to make bootstrap navbar work in my Rails movie review application

I included all the files that are needed to run the bootstrap, but the navbar is not working, it looks like normal HTML.

gemfile:

source 'https://rubygems.org'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"
end


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '~> 5.2', '>= 5.2.4.2'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use Puma as the app server
gem 'puma', '~> 3.7'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets

# See https://github.com/rails/execjs#readme for more supported runtimes

# Use Redis adapter to run Action Cable in production

# Use Capistrano for deployment

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console

  gem 'web-console', '>= 3.3.0'
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem

gem 'jquery-turbolinks', '~> 2.1'
gem 'rails-ujs', '~> 0.1.0'
gem 'sassc-rails', '~> 2.1', '>= 2.1.2'

application.js:

//= require rails-ujs
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require bootstrap-sprockets
//= require_tree .

application.scss:

@import "bootstrap-sprockets";
@import "bootstrap";

This is the header file that I used for Navbar, _header.html.erb:

<nav class="navbar" navbar-default role="navigation">
  <div class="container">
  <div class="navbar-header">
    <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
      <span class="sr-only"> Toggle Navigation</span>
      <span class="icon-bar"> </span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>      
    </button>
    <%= link_to "Movies Reviews", root_path, class: "navbar-brand" %>
  </div>

  <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
    <ul class="nav navbar-nav">
    <% if user_signed_in? %>
      <li><%= link_to "New Movie" , new_movie_path, class: "active" %> </li>
      <li> <%= link_to "Account", edit_user_registration_path %></li>
      <% else %>
        <li> <%= link_to "Sign Up", new_user_registration_path, class: "active" %></li>
        <li> <%= link_to "Sign In", new_user_session_path, class: "active" %></li>
      <% end %>
    </ul>
    <form class="navbar-form navbar-right">
      <div class="form_group">
        <input type="text" class="form-control" placeholder="search">
      </div>
      <button type="submit" class="btn btn-default">Submit</button>
    </form>
  </div>
  </div>
</nav>

And application.html.erb:

<!DOCTYPE html>
<html>
  <head>
    <title>Moviereview</title>
    <%= csrf_meta_tags %>

    <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track': 'reload' %>
    <%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>
  </head>

  <body>
    <%= render 'layouts/header' %>
    <% flash.each do |name, msg|%>
    <%= content_tag(:div ,msg, class:"alert alert_info")%>
    <% end %>
    <%= yield %>
  </body>
</html>
