This is what I have on my application.html.erb file.
<head>
<title>Software & Cia.</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.0/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolineks-track': 'reload' %>
<%= csrf_meta_tags %>
</head>
If I delete the application stylesheet_link_tag, bootstrap works just fine, but I want to add my own styling to some parts. Sorry for the noobish question, but tried to find a solution and can't get it working.
My application.scss is
#import "bootstrap-sprockets";
#import "boostrap";
My application.js is
//= require jquery
//= require jquery_ujs
//= require bootstrap-sprockets
//= require turbolinks
//= require_tree . here
If you want to use Bootstrap in rails, it's a good way to use the bootstrap gem (same for jquery)
gem 'turbolinks', '~> 5'
gem 'bootstrap', '~> 4.1.1'
gem 'jquery-rails'
This way you keep your application <head> clean:
<head>
<title>Software & Cia.</title>
<%= csrf_meta_tags %>
<%= csp_meta_tag %>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>
</head>
Now your assets/stylesheets folder can be organize like that:
stylesheets
|_ custom_folder
| |_ custom1.scss
| |_ custom2.scss
|
|_ application.scss
|_ another_custom.scss
And you import all these files, bootstrap included, in your application.scss:
#import "bootstrap";
#import "custom_folder/custom1";
#import "custom_folder/custom2";
#import "another_custom";
If you have multiple files inside a custom folder, you can even
create an index.scss where you import all your files and just import
"custom_folder/index" in application.scss
If you override some boostrap variables in a file, import this one before bootstrap

In my production environment, I noticed Turbolinks was not caching assets between pages. When I come on the first page of my application, my javascript bundle gets loaded, so as my CSS. When I then get to another page with a link, I can see in the chrome devtools, network tab, that they are reloaded (HTTP code 200).
application.html.erb
<html>
<head>
<title>My title</title>
<meta name="description" content="My description">
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta name="robots" content="index, follow">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<%= csrf_meta_tags %>
<%= action_cable_meta_tag %>
</head>
<body class="<%= body_user_class %> <%= controller.controller_name %>">
// Stuff
</body>
</html>
application.js
//= require turbolinks
//= require jquery
//= require jquery.slick
//= require jquery-ui/sortable
//= require rails-ujs
//= require_tree ./components
The fingerprint of the assets remains the same between the first and the second page, so I don't think the issue comes from there.
I can understand why my bootstrap asset is reloaded, as it is referenced as a classical resource without using rails. But why are my application's js and css reloaded?
In your application JavaScript bundle, you have the following:
document.addEventListener("turbolinks:before-visit", function(e) {
e.preventDefault(),
window.location = e.data.url
})
This cancels the default Turbolinks behaviour. If you remove this event listener, it should work as expected.
Using the polymer-rails gem with Rails 4.2 I am able to use the predefined polymer elements such as the paper element set and the iron element set.
However when I make my own elements they are not rendered.
E.g. I created an element with this command
rails g polymer:component testing
and I left it untouched
/app/assets/components/testing/testing.html looks like this:
<dom-module id="testing">
<link rel="stylesheet" href="testing.css" />
<template>
<h2>Testing</h2>
</template>
<script src="testing.js"></script>
</dom-module>
/app/assets/components/testing/testing.js looks like this:
Polymer({
is: "testing"
});
/app/assets/components/application.html.erb has this:
//= require polymer/polymer
//= require paper-styles/paper-styles
//= require iron-icons/iron-icons
//= require paper-tooltip/paper-tooltip
//= require easy-paper-tabs/easy-paper-tabs
//= require testing/testing
the <head> of /app/views/layouts/application.html.erb is this:
<head>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1.0"/>
<title><%= full_title(yield(:title)) %></title>
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= javascript_include_tag "https://www.google.com/jsapi", "chartkick" %>
<%= csrf_meta_tags %>
<%= favicon_link_tag %>
<%= html_import_tag 'application', 'data-turbolinks-track' => true %>
</head>
When I put the tag <testing></testing> into a view I expect to see the h2 heading "Testing", but I don't. Instead nothing is rendered there. When I inspect the page I just see the empty tag <testing></testing>.
What am I missing?
I've tried putting the <testing></testing> tag into different views
I've tried replacing <%= html_import_tag 'application', 'data-turbolinks-track' => true %> with <%= html_import_tag 'application' %> in /app/views/layouts/application.html.erb
I've tried putting the custom component into /vendor/assets/components/testing/ instead of /app/assets/components/testing/
For each thing I tried I restarted the server.
I noticed the console logged an error that said
Failed to execute 'registerElement' on 'Document': Registration failed for type 'testing'. The type name is invalid.
so I googled it and found that the web-components spec bizarrely requires all user-created elements to have a hyphen in their name! There's not much documentation about this - it's like secret knowledge.
Putting a hyphen in the name of the element fixes my problem.
So im trying to install gem foundation-rails and it keeps giving me an error:
console error:
Browser error
Solution worked:
removing //= require foundation from appliaton.js fixed the problem but i dont think this is the right solution. any suggestions that worked for you guys? thank you.
Application.css
*= require_tree .
*= require_self
*= require foundation_and_overrides
Application.js
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title><%= content_for?(:title) ? yield(:title) : "Untitled" %></title>
<%= stylesheet_link_tag "application" %>
<%= javascript_include_tag "application", 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
</head>
I think you have to include the gem 'execjs' and gem 'therubyracer' in your gem file . Add gem 'execjs' and gem 'therubyracer' to the gemfile and bundle install.
I am new to rails and implementing a demo app. I have this code in my 'app/view/layout/applicatio.html.erb' file:
<%= stylesheet_link_tag "scaffold" %>
but when I run it and debug in my browser I see this path expands to:
<link href="/assets/scaffold.css" media="screen" rel="stylesheet" type="text/css">
I am not able to understand that from where this assets folder is coming into picture? this is also causing the problem in the loading of my stylesheets.
Read this stuff here.
http://guides.rubyonrails.org/asset_pipeline.html
In application.html.erb
<%= stylesheet_link_tag "application", :media => "all" %>
in the applications.css
*= require_tree .
This row means all .css file in app/assets/stylesheets will be included.
Im just looking for a little clarity to better my understanding of the Rails asset pipeline. I have placed my stylesheets and javascripts within app/assets/javascripts and app/assets/stylesheets. Now i am trying to get these views to render on my page but so far nothing is showing.. I wanted to see if someone could confirm if the following looks correct
In my layouts/application i have
<%= stylesheet_link_tag "fullcalendar" %>
<%= stylesheet_link_tag "application" %>
<%= javascript_include_tag "jquery.js" %>
<%= javascript_include_tag "jquery.rest.js" %>
<%= javascript_include_tag "rails.js" %>
<%= javascript_include_tag "application.js" %>
<!-- these are needed for the calendar. -->
<%= javascript_include_tag "jquery-ui-1.8.11.custom.min.js" %>
<%= javascript_include_tag "fullcalendar.js" %>
<%= javascript_include_tag "calendar.js" %>
And my index.html.erb looks like
<html>
<head>
<link href="/stylesheets/fullcalendar.css" media="screen" rel="stylesheet" type="text/css" />
<script type='text/javascript' src='/javascripts/jquery.js'></script>
<script type='text/javascript' src='/javascripts/fullcalendar.js'></script>
<script type='text/javascript' src='/javascripts/calendar.js'></script>
<script type='text/javascript' src='/javascripts/jquery-ui-1.8.9.custom.min.js'></script>
<script type='text/javascript' src='/javascripts/jquery.rest.js'></script>
Am I missing something or just being a real novice ( All constructive criticism welcome)
in Your layouts/application you just need this:
<%= javascript_include_tag "application" %>
<%= stylesheet_link_tag "application", media: "all" %>
and in app/assets/stylesheets/application.css
you just need:
*=require_self
*=require_tree .
and in app/assets/javascripts/application.js
//= require jquery
//= require jquery_ujs
//= require_tree .
And there's o need to include all the files
You'll have some problems in production if you include js files, to avoid it, you should add such files, ex: "fullcalendar.js" in config/production.rb, config.assets.precompile += %W(fullcalendar.js), and then run rake asset:precompile
You can see a quick overview in Ryan Bates Video: #279 Understanding the Asset Pipeline.
For more info go to the RailsGuide: Asset Pipeline.
Both helped me a lot.
