I have a ruby on rails application which I am building using bootstrap which looks great when running locally:
I commit my code to master branch on git and then push to my heroku master. When I visit my heroku URL I get this page :
https://whats-on-today.herokuapp.com/
Not so great. I can see there are some 404 errors:
HTTP 404 - GET https://whats-on-today.herokuapp.com/assets/application-96ded6f70c682e6f9f3a1ae3eb283ae0.js

HTTP 404 - GET https://whats-on-today.herokuapp.com/assets/application-2b56caae7bd0b485593c1fca2397cc26.css
I have no idea what these css files are and why they exist. My application layout code looks like this :

Can anybody explain why the code when deployed to heroku looks like this :
Use a gem for rails 4 on production
gem 'rails_serve_static_assets', group: :production
or use a rails_12factor gem (This gem adds two other gems rails_serve_static_assets and rails_stdout_logging)
gem 'rails_12factor', group: :production

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:

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 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.

The above code is working for all the links except the links in categories.How can I dynamically give active class to links generated from the categories in nav bar.

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 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 am following the tutorial for devise and cancan integration for rails.

</div>
<% end %>
<% end %>
</div>
Do you shure that you correctly include bootstrap javascript files?
In application.js should be that line:
//= require bootstrap
Change this
<a class="close" data-dismiss="alert" href="">x</a>
to this
<a class="close" data-dismiss="alert" href="#">x</a>
Now, the page will no longer redirect to root url.
[edit]
an empty href="" in <a> tag reloads the page. so, you can change it to the following:
href="#" adds an extra entry to the browser history (which is annoying when e.g. back-buttoning).
href="javascript:;" does not seem to have any problems (other than looking messy and meaningless)
