I have an application which uses an engine (included by Gemfile gem my_engine, path=> '../my_engine'). It works nice with rails server. I decided to move it to nginx with passenger, but I get an error.
Sprockets::Helpers::RailsHelper::AssetPaths::AssetNotPrecompiledError
auth_engine.css isn't precompiled
Extracted source (around line #1):
1: <%= stylesheet_link_tag "auth_engine" %>
2:
3: <div class="form">
4: <% flash.each do |key, value| %>
auth_engine.css is located in my_engine/app/assets/stylesheets
How to fix this?
It looks like you're just linking to that one stylesheet separately instead of just letting rails roll into application.css. In that case, you should just move it to the public/assets/stylesheets folder to use it without compiling it.

I have an app that supposed to generate PDFs with a gem called wicked_pdf. When I try to invoke it, I get an error. The logs give a hint of the problem:
ActionView::Template::Error (The asset "qr-code.js" is not present in the asset pipeline.
):
1: <%= javascript_pack_tag 'qrcode' %>
2: <%= wicked_pdf_javascript_include_tag "qr-code" %>
3:
4: <%=wicked_pdf_stylesheet_link_tag 'pdf' %>
5: <p id="notice"><%= notice %></p>
app/views/health_cards/show.pdf.erb:2
app/controllers/health_cards_controller.rb:21:in `block (2 levels) in show'
app/controllers/health_cards_controller.rb:12:in `show'
app/controllers/application_controller.rb:31:in `handle_fhir_errors'
However, I noticed that there is a file the application's javascript directory at:
./app/javascript/packs/qrcode.js
so I changed the include statement at line 2 above from qr-code to qrcode but it doesn't make a difference. Given the parent directory is called "packs", it looks like it could be doing some fancy caching somewhere. How can I rebuild my assets and/or fix the issue?
Everything is working perfectly locally but when I tried to put the app live I've got this error:
Showing /home/rails/app/views/layouts/application.html.erb where line #9 raised:
end of file reached
(in /home/rails/app/assets/stylesheets/global.css.scss)
this is line 9
<%= stylesheet_link_tag "application" %>
when I remove this line I get errors for javascript:
<%= javascript_include_tag "vendor/modernizr" %>
What is the issue and how can it be fixed?
Also not sure about the "end of file reached global.css.scss?"
below is this:
app/views/layouts/application.html.erb:9:in `_app_views_layouts_application_html_erb__92412405316489023_40891780'
app/controllers/site_controller.rb:42:in `index'
On line 42 is the word "render"
def index
render
end
Many thanks
It should have something to do with precompile. Try cleaning the asset precompile temp folder.
If that doesn't solve it, pl post the stack trace.
As a bit of pre-text, I am used to Rails 2 but started building a sample app to get used to Rails 4 and I am having a nightmare with Sprockets and the asset pipeline even after reading the official guide and every question I can find on SO.
My css and js are included like so in my main view file:
<head>
...
<%= stylesheet_link_tag "application", media: "all" %>
<%= stylesheet_link_tag "style-responsive", media: "all" %>
<%= stylesheet_link_tag params[:controller], :media => "all" if stylesheet_exists?(params[:controller]) %>
<!-- HTML5 shim and Respond.js IE8 support of HTML5 elements and media queries -->
<!--[if lt IE 9]>
<%= javascript_include_tag 'html5shiv' %>
<%= javascript_include_tag 'respond.min' %>
<![endif]-->
...
</head>
....
<%= javascript_include_tag "jquery-1.10.2.min" %>
<%= javascript_include_tag "jquery-ui-1.9.2.custom.min" %>
<%= javascript_include_tag "jquery-migrate-1.2.1.min" %>
<%= javascript_include_tag "bootstrap.min" %>
<%= javascript_include_tag "modernizr.min" %>
<%= javascript_include_tag params[:controller] if javascript_exists?(params[:controller]) %>
stylesheet_exists? and javascript_exists? are helper functions as I only want to include certain files when they are needed as opposed to the rest which are needed on every page.
The first error is:
Asset filtered out and will not be served: add `Rails.application.config.assets.precompile += %w( style-responsive.css )` to `config/initializers/assets.rb` and restart your server
If I then add that to assets.rb and restart, it moves on and the issue is repeated for every stylesheet_link_tag and javascript_include_tag in my view.
I could live with that even if it doesn't seem right but this comes crashing down when the interpreter gets to
<%= javascript_include_tag params[:controller] %>
Would I then need to also include every js file that I create for each controller? This seems wrong that I would have to constantly update the file whenever I create a new asset file.
In my application.css.erb I only have
*= require_self.
but I do have the old fashioned CSS #import for some stylesheets:
#import url(http://fonts.googleapis.com/css?family=Open+Sans:400,300,300italic,400italic,600,600italic,700,700italic,800,800italic);
#import url('bootstrap.min.css');
#import url('bootstrap-reset.css');
#import url('jquery-ui-1.10.3.css');
#import url('<%= asset_path 'css/font-awesome.min.css' %>');
#import url('custom-ico-fonts.css');
but all of these seem to work fine and don't need to be mentioned in assets.rb.
I have no requires set in application.js.
TLDR I think I am using Sprockets and the Asset Pipeline incorrectly, could someone please point out what it is I'm doing wrong and point me in the right direction?
I read about some similar issues to do with the sprocket-rails gem version 2.2.3 but I have 2.2.4 installed which is meant to have fixed any problems that existed in the previous version.
Rails 4.2.1
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-linux]
sprockets (3.0.1, 2.12.3)
sprockets-rails (2.2.4)
Sprockets wants to compact everything into a single file and minify it, so typically the pattern is to include all your javascript/stylesheets in the application manifests. There are plenty of good reasons for this pattern.
Since it appears you have removed the = require_tree . lines, this is not happening automatically and thus Rails wants to know about each individual file you plan to include separately via the assets.precompile configuration option. If requiring the entire directory is too aggressive, break your assets into subfolders and be more explicit about what you want to include.
Sprockets is relatively brittle and fighting against it is an uphill battle. So in both cases (JS/CSS), you should include it all and use selectors that are smart enough to scope page-specific styles or JS to that page.
That said, sometimes we cannot avoid having certain assets omitted from global inclusion. If you need to exclude a specific file from your manifest use a stub directive and include it separately with the HTML tag helpers.
Also note that you can have additional manifests (other files that include = require ... directives of their own) ... so long as you add those to the assets.precompile list.
The combination of stub and require directives and additional manifests should give you enough flexibility to organize your assets to your liking and make adding additional assets frictionless.
Firstly I'm still busy learning RoR so my understanding is limited. I created a new simple project and generated my first scaffold named 'Person'. When I start up my WEBrick server I go to localhost:3000/people I get the following runtime error:
ExecJS::RuntimeError in People#index
Showing C:/Users/Dean/Desktop/guestbook/app/views/layouts/application.html.erb where line #6 raised:
(in C:/Users/Dean/Desktop/guestbook/app/assets/javascripts/people.js.coffee)
Extracted source (around line #6):
3: <head>
4: <title>Guestbook</title>
5: <%= stylesheet_link_tag "application", :media => "all" %>
6: <%= javascript_include_tag "application" %>
7: <%= csrf_meta_tags %>
8: </head>
9: <body>
If any more clarification is needed please let me know and I'll gladly update my question.
I'm no expert but it looks like it's something to do with.. the coffeescript gem? I'm really just spitballin' here... Thanks in advance!
people.js.coffee:
# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://jashkenas.github.com/coffee-script/
ExecJS::RuntimeErrors are typically caused by syntax errors in your coffeescript. Check your people.js.coffee file around line 6 and make sure it is syntactically correct. If you are relatively unfamiliar with coffeescript, http://js2coffee.org/ converts between JS and coffee and might be helpful. .js.coffee files will only accept coffeescript.
I have just installed a base installation of rails and have edited the main page to view some basic html and a link to create a new blog post via ruby in the corresponding 'erb' file. I am trying to add some additional ruby commands on this same page via <%= %> tags.
<h1>Hello, Rails!</h1> <%= link_to "My Blog", posts_path %>
<p>
<%= require 'rubygems' %>
<%= require 'simplegeo' %>
<%= SimpleGeo::Client.set_credentials('token', 'secret') %>
<%= a = SimpleGeo::Client.get_context(coordinates,coordinates); a %>
</p>
When I load this page , I get the following error: no such file to load -- simplegeo
Can someone point me in the right direction? Many thanks!
In Rails 3, you need to add this gem to your "Gemfile" .. follow this: http://gembundler.com/rails3.html
Remove this completely.. Never do this in your views
<%= require 'rubygems' %>
<%= require 'simplegeo' %>
Once you restart your rails server, if you added "simplegeo" to your gemfile, it'll be auto-required.
Move this to your controller to start
SimpleGeo::Client.set_credentials('token', 'secret')
#simple_geo_client = SimpleGeo::Client.get_context(coordinates,coordinates)
Then in your view, you can access any variable that starts with #
To get started in Rails, check out http://railsforzombies.org/
In rails 3.x, you use Bundler to specify gems. No need to require, especially in views.
Correct way is:
Open Gemfile
Set/List required gems inside using format:
source :rubygems
gem "simplegeo"
gem "some_other_gem"
Run bundle install (or just bundle) command in console.
now restart your server and gems are auto required.
Check out Rails guide on how to start.
Most probably you did not install Simplegeo gem properly, or did not attach it correctly in you IDE.
