I am putting together a basic website from One Month Rails and can't seem to figure out how to get the navigation bar to show at the top. I have spent a few hours and would like to go to the community. Here is the code from the _header.html.erb (using bootstrap sass)
<div class="navbar navbar">
<div class="navbar-inner">
<div class="container">
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<a class="brand" href="#">Project name</a>
<div class="nav-collapse collapse">
<ul class="nav">
<li>
<%= link_to 'Home', root_path %>
</li>
<li>
<%= link_to 'About', about_path %>
</li>
</ul>
<ul class="nav pull-right">
<li><%= link_to 'Login', '#' %></li>
</ul>
</div>
</div>
</div>
</div>
Here is the code from the application.html.erb tab:
<!DOCTYPE html>
<html>
<head>
<body>
<title>One Month Rails</title>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
<%= tag :meta, name: "viewport", content: "width=device-width, initial-scale=1.0" %>
</head>
<body>
<%= render 'layouts/header' %>
<div class="container">
<%= yield %>
<%= render 'layouts/footer' %>
</div>
</body>
</html>
You seem to have some HTML errors in application.html.erb. But most modern browsers will fix those errors for you when loading the page. Here's a better version:
<!DOCTYPE html>
<html>
<head>
<title>One Month Rails</title>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
<%= tag :meta, name: "viewport", content: "width=device-width, initial-scale=1.0" %>
</head>
<body>
<%= render 'layouts/header' %>
<div class="container">
<%= yield %>
<%= render 'layouts/footer' %>
</div>
</body>
</html>
You should also make sure your _header.html.erb is in app/views/layouts/.
Finally, don't forget to add bootstrap's css file to app/assets/stylesheets/.

I have had these issues with my navbar and can't find what am I doing wrong. In the beginning, I just took out the code for the toggle and the link for the About page would be where it should; on the right-hand side of my navbar. Now I got to the point where I need the hamburger nav menu, so I have to add the toggle code, but then the link to my About page disappears completely and there is no toggle either. The second issue is the appearance of the little bar on the left side of my logo.
Screenshot of the page:
My code:
<!DOCTYPE html>
<html>
<head>
<title>Saasapp</title>
<%= csrf_meta_tags %>
<%= csp_meta_tag %>
<link href="https://fonts.googleapis.com/css?
family=Open+Sans:400,700,800" rel="stylesheet">
<%= stylesheet_link_tag 'application', media: 'all', 'data-
turbolinks-track': 'reload' %>
<%= javascript_pack_tag 'application', 'data-turbolinks-track':
'reload' %>
</head>
<body>
<nav class="navbar navbar-default navbar-static-top" role="navigation">
<div class='container'>
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#navbarNav" aria-expanded="false">
<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 root_path, class: "navbar-brand" do %>
<i class="fas fa-users"></i> DevMatch
<% end %>
</div>
<div class="collapse navbar-collapse navbar-right" id="navbarNav">
<ul class="navbar-nav">
<li>
<%= link_to "About", about_path, id:
"navbar-right" %>
</li>
</ul>
</div>
<!-- /.navbar-collapse -->
</div>
</nav>
<%= yield %>
</body>
</html>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav navbar-right">
<li>
<%= link_to "About", about_path, id: "navbar-right" %>
</li>
</ul>
</div>
The navbar-right class should be added to the ul instead of the div.
The toggle will show up if you make you screen smaller.
I am trying to dry up my code and decided to use a partial for my page title and pass a local variable into it. It works, but I want to know if I am conforming to the Rails best practice.
partials/_page-header.html.erb
<section class="hero is-primary">
<div class="hero-body">
<div class="container">
<h1 class="title">
<%= title %>
</h1>
<h2 class="subtitle">
Hero subtitle
</h2>
</div>
</div>
</section>
static_pages/home.html.erb
I would add this to the top of all my views
<% provide(:title, 'Home') %>
...
application.html.rb
<!doctype html>
<html lang="en">
<head>
<%= render 'partials/head' %>
<%= render 'partials/head-scripts' %>
<%= render 'layouts/shim' %>
</head>
<body>
<%= render 'partials/nav' %>
<%= render 'partials/page-header', title: yield(:title) %>
<section class="section">
<div class="container">
<div class="content">
<%= yield %>
</div>
</div>
</section>
<%= render 'partials/footer' %>
<%= render 'partials/footer-scripts' %>
</body>
</html>
I am currently using Twitter bootstrap for front end of website. I'm writing the code for navbar in application.html.erb file. I'm not able to give active class to some of the links. Here is my application.html.erb file.

As a Rails newbie, I am running into an issue in which I am struggling to figure out.
Im rendering a header universally across the four pages of my application which consists of home, about, (signup and signin which are administered through devise).
The header is fine across the home and about pages, however in the devise pages the logo image specifically arrives broken yet all of the other elements appear in tact. Any help would be appreciated.

That's the problem with how you set the path to your logo. Making it absolute or better use image_tag.
<img src="/assets/nippon.svg" ...
Notice, I've added / (forward slash) before assets.
A better way of doing it would be:
<%= image_tag('nippon.svg', alt: "Nippon Beauty", class: "navbar-brand-icon") %>
I'm using the bootstrap-sass gem and for some reason in the navbar I'm using the active class for one of the li's below, however it doesn't appear pressed down.
application.html.erb:
<!DOCTYPE html>
<html>
<head>
<title><%= yield(:title) %></title>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
<body id="<%= params[:controller].parameterize %>_controller">
<div class="container">
<div class="row">
<div class="span12">
<div class="navbar">
<div class="navbar-inner">
<%= link_to 'evoALL', root_path,
html_options = {:class => 'brand'} %>
<% navArr = ["Dashboard", "Help People",
"Get Help", "Contact Us"] %>
<% flash.each do |key, value| %>
<p class="lead"><%= value %></p>
<% end %>
<ul class="nav">
<% navArr.each do |value| %>
<li>
<a
<% if (yield(:navActive)==value) %>
class="active"
<% end %>
href="#">
<%=value%>
</a>
</li>
<% end %>
</ul>
</div>
</div>
</div>
</div>
<%= yield %>
<div class="container">
<div id="footer"><!-- footer start -->
<div class="row-fluid">
<div class="span12">
<p class="pull-right">
© <%= Date.today.year %>
</p>
</div>
</div>
</div><!-- footer end -->
</div>
</div> <!-- close container div -->
</body>
</html>
index.html.erb for the view file of the index method of the main controller that gets routed to for the root of the application:
<%= provide(:title, 'evoALL') %>
<%= provide(:navActive, 'Get Help') %>
<div class="container">
<div class="row">
<div class="span12">
<p>Needs Home Page</p>
</div>
</div>
</div>
I was applying the active class to the a tag instead of the li tag.
The correct solution would be to replace this:
<% navArr.each do |value| %>
<ul>
<li>
<a
<% if (yield(:navActive)==value) %>
class="active"
<% end %>
href="#">
<%=value%>
</a>
</li>
</ul>
<% end %>
with this:
<ul class="nav">
<% navArr.each do |value| %>
<li
<% if (yield(:navActive)==value) %>
class="active"
<% end %>>
<a href="#">
<%=value%>
</a>
</li>
<% end %>
</ul>
