问题
I am running a development server and I'm trying to load some static pages and files (images, css and javasripts) in my rails application for testing. (In general, I'm new in rails. The Rails installation has been done on Linux subsystem in Windows 10).
Although I have placed the files in assets/images, assets/javascripts and assets/stylesheets I couldn't manage to read these files in my test apprication when server runs. I receive the following errors almost for all files I have added:
ActionController::RoutingError (No route matches [GET] "/assets/javascripts/jquery.min.js"):
ActionController::RoutingError (No route matches [GET] "/assets/javascripts/bootstrap.min.js"):
ActionController::RoutingError (No route matches [GET] "/assets/javascripts/jqBootstrapValidation.js"):
and for images
ActionController::RoutingError (No route matches [GET] "/assets/images/portfolio/dreams-preview.png"):
The same applies for some css files also (not all).
I tried several ideas I found here in order to solve this but I had no luck. I tried to setup:
config.serve_static_files = true
in development.rb and
rake assets:precompile
Obviously, these files are not visible by rails application but I still don't understand what I have to do to make them visible. Can you please help me on this?
回答1:
You need to include these files in application.js manully or just write //= require_tree . to load all js
Similarly, you have to work for css. Add *= require_tree . in application.css.

Finally, in order to resolve this error and transfer my static pages to Rails I had to modify my homepage.html.erb as follows:
Stylesheet links:
<%= stylesheet_link_tag "bootstrap.min.css" %>
the following also works:
<link href="assets/bootstrap.min.css" rel="stylesheet">
Javascript include:
<%= javascript_include_tag "bootstrap.min.js" %>
In general, I found that no precompilation is necessary. I tested and it works with or without precompilation. The following also works:
<script src="assets/bootstrap.min.js"></script>
Tag for images:
<%= image_tag("portfolio/dreams-preview.png", class: "img-responsive img-centered") %>
Rails use by default the normal path for images (assets/images). The full path should not be used. Unless the path for images is different, use only the path deeper than assets/images, if exists.
No changes were made in application.html.erb but precompilation for javascripts and stylesheets is necessary in assets.rb:
Rails.application.config.assets.precompile += ['agency.min.js', 'agency.min.css', ...]
Eventually the site works, although some conflicts in the execution of javascripts might be appear.

I was actually getting these kind of errors too. Mine looked like this:
F, [2018-06-16T17:46:02.121588 #6963] FATAL -- :
ActionController::RoutingError (No route matches [GET] "/assets/theme/bootstrap.min.css"):
[2018-06-18T12:55:20.169664 #18951] FATAL -- :
ActionController::RoutingError (No route matches [GET] "/assets/theme/main.css"):
And I never added any reference to these files in my application. So I did not immediately realize why these specific css files were being requested. Well, it happens that after my application received a 404 error or 500 error, it would load the corresponding 404.html or 500.html in the public directory. Those directories did reference these css files:
<head>
<title>PAGE NOT FOUND (404)</title>
<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1, maximum-scale=1">
<link rel="stylesheet" href="/assets/theme/bootstrap.min.css">
<link rel="stylesheet" href="/assets/theme/main.css">
</head>
So remove the references here and errors will go away.
