I am trying to update my asset directories within my scss config.rb file. I need to access compass mixins such as height: image-height($image); For this to work, my images path has to be relative to my project’s image directory, defined in your config.rb file. However, I cannot get this to work. I have used the compass url_helpers but nothing seems to be changing. No matter how I update the assets in my config.rb, the following is returned when declaring an image variable in my scss..."No such file or directory # rb_sysopen - /private/var/www/websites/gc/app/sites/all/themes/merge/scss/../images/../search-b-image.jpg" Where is this ../images/.. coming from if its not in my config.rb? Any help is much appreciated.
config.rb file is:
http_path = "/"
css_dir = "compiled_css"
sass_dir = "scss"
images_dir = "img"
javascripts_dir = "js"
environment = :development
relative_assets = true
output_style = :expanded
output_style = :compressed
preferred_syntax = :scss

I am new in ruby on rails and I want to read data from a JSON file from a specified directory, but I constantly get an error in chap3(File name)
Errno::ENOENT in TopController#chap3. No such file or directory # rb_sysopen - links.json.
In the console, I get a message
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
How I can fix that?
Code:
require "json"
class TopController < ApplicationController
def index
#message = "おはようございます！"
end
def chap3
data = File.read('links.json')
datahash = JSON.parse(data)
puts datahash.keys
end
def getName
render plain: "名前は、#{params[:name]}"
end
def database
#members = Member.all
end
end
JSON file:
{ "data": [
{"link1": "http://localhost:3000/chap3/a.html"},
{"link2": "http://localhost:3000/chap3/b.html"},
{"link3": "http://localhost:3000/chap3/c.html"},
{"link4": "http://localhost:3000/chap3/d.html"},
{"link5": "http://localhost:3000/chap3/e.html"},
{"link6": "http://localhost:3000/chap3/f.html"},
{"link7": "http://localhost:3000/chap3/g.html"}]}
I would change these two lines
data = File.read('links.json')
datahash = JSON.parse(data)
in the controller to
datahash = Rails.root.join('app/controllers/links.json').read
Note: I would consider moving this kind of configuration file into the /config folder and creating a simple Ruby class to handle it. Additionally, you might want to consider paths instead of URLs with a host because localhost:3000 might work in the development environment but in production, you will need to return non-localhost URLs anyway.
Rails use the content of file in the controller
#data = File.read("#{Rails.root}/app/controllers/links.json")
We are using gradle.plugin.org.detoeuf:swagger-codegen-plugin.
We want to change the content of the build.gradle file in the output directory.
We added the gradle.build file to the .swagger-codegen-ignore but BOTH .swagger-codegen-ignore file and gradle.build file are re-created every time we call the swagger task.
Our swagger section looks like this
swagger {
inputSpec = "${project.projectDir}/swagger/backoffice-service-api-swagger.json"
outputDir = file("${project.projectDir}/../backoffice-service-api-client/")
lang = 'java'
additionalProperties = [
'invokerPackage' : 'com.aaa.bbb.backoffice.service',
'modelPackage' : 'com.aaa.bbb.backoffice.service.model',
'apiPackage' : 'com.aaa.bbb.backoffice.service.api',
'dateLibrary' : 'joda',
'groupId' : 'com.aaa.bbb',
'artifactId' : 'backoffice-service-api-client',
'artifactVersion' : '1.0.0',
'hideGenerationTimestamp': 'true',
'dateLibrary' : 'java8'
]
systemProperties = ["apiTests" : "false"]
}
.swagger-codegen-ignore file looks like this -
# Swagger Codegen Ignore
# Generated by swagger-codegen https://github.com/swagger-api/swagger-codegen
# Use this file to prevent files from being overwritten by the generator.
# The patterns follow closely to .gitignore or .dockerignore.
# As an example, the C# client generator defines ApiClient.cs.
# You can make changes and tell Swagger Codgen to ignore just this file by uncommenting the following line:
#ApiClient.cs
# You can match any string of characters against a directory, file or extension with a single asterisk (*):
#foo/*/qux
# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
#foo/**/qux
# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
# You can also negate patterns with an exclamation (!).
# For example, you can ignore all files in a docs folder with the file extension .md:
#docs/*.md
# Then explicitly reverse the ignore rule for a single file:
#!docs/README.md
build.gradle
You can add ignoreFileOverride option in additionalProperties as below. The files provided in ignoreFileOverride option do not exists in project, then swagger-codegen will generate them and if files exist in project then swagger-codegen will ignore them.
swagger {
inputSpec = "${project.projectDir}/swagger/backoffice-service-api-swagger.json"
outputDir = file("${project.projectDir}/../backoffice-service-api-client/")
lang = 'java'
additionalProperties = [
'invokerPackage' : 'com.aaa.bbb.backoffice.service',
'modelPackage' : 'com.aaa.bbb.backoffice.service.model',
'apiPackage' : 'com.aaa.bbb.backoffice.service.api',
'dateLibrary' : 'joda',
'groupId' : 'com.aaa.bbb',
'artifactId' : 'backoffice-service-api-client',
'artifactVersion' : '1.0.0',
'hideGenerationTimestamp': 'true',
'dateLibrary' : 'java8',
'ignoreFileOverride' : '.swagger-codegen-ignore,build.gradle'
]
systemProperties = ["apiTests" : "false"]
}
Is there a way to do 'hot code reloading' with a Rails application in the development environment?
For example: I'm working on a Rails application, I add a few lines of css in a stylesheet, I look at the browser to see the modified styling. As of right now I have to refresh the page with cmd-r or by clicking the refresh button.
Is there a way to get the page to reload automatically when changes are made?
This works nicely in the Phoenix web framework (and I'm sure Phoenix isn't the only framework in this feature). How could a feature like this be enabled in Ruby on Rails?
I am using this setup reloads all assets, js, css, ruby files
in Gemfile
group :development, :test do
gem 'guard-livereload', '~> 2.5', require: false
end
group :development do
gem 'listen'
gem 'guard'
gem 'guard-zeus'
gem 'rack-livereload'
end
insert this in your development.rb
config.middleware.insert_after ActionDispatch::Static, Rack::LiveReload
i have this in my guard file
# A sample Guardfile
# More info at https://github.com/guard/guard#readme
## Uncomment and set this to only include directories you want to watch
# directories %w(app lib config test spec features) \
# .select{|d| Dir.exists?(d) ? d : UI.warning("Directory #{d} does not exist")}
## Note: if you are using the `directories` clause above and you are not
## watching the project directory ('.'), then you will want to move
## the Guardfile to a watched dir and symlink it back, e.g.
#
# $ mkdir config
# $ mv Guardfile config/
# $ ln -s config/Guardfile .
#
# and, you'll have to watch "config/Guardfile" instead of "Guardfile"
guard 'livereload' do

I am using zeus instead of spring on this setup.
Run guard
Open localhost:3000 and you are good to go.
This should resolve your question, and have blazing reload times better than browserify.
I commented out guard looking at test directories if you want you can uncomment those lines if your are doing TDD.
CSS hot swapping and auto-reload when HTML/JS changes can be achieved with guard in combination with livereload: https://github.com/guard/guard-livereload
This gem would auto reload when you make changes to js elements(Not css or ruby files).
https://github.com/rmosolgo/react-rails-hot-loader
Never seen css hot code reloading in rails platform.
I'm trying to create an app with Rails 4 that should be usable without internet connection.
I've heard about html5 application cache and the rack-offline gem which is the approach I took.
Now, it seems that it's not working properly on Rails 4 since the /application.manifest only shows:
CACHE MANIFEST
# dd1ba6bba9339ef83f9c1225c70289dd6326d3caae01b0d52b502381030dc78f
404.html
422.html
500.html
NETWORK:

Also, I'm using assets precompile so the application.js, application.css and the image files has a fingerprint in their names, something like application-e8cc2fba8275c884c.js.
I made my own solution in a generate_appcahe_manifest.rake file and put it in /lib/tasks folder.
task :generate_appcache_file => ['deploy:precompile_assets', 'html5_manifest']
desc "Create html5 manifest.appcache"
task :html5_manifest => :environment do
puts 'Creating appcache manifest file...'
File.open("public/manifest.appcache", "w") do |f|
f.write("CACHE MANIFEST\n")
f.write("# Version #{Time.now.to_i}\n\n")
f.write("CACHE:\n")
assets = Dir.glob(File.join(Rails.root, 'public/assets/**/*'))
assets.each do |asset|
if File.extname(asset) != '.gz' && File.extname(asset) != '' && File.extname(asset) != '.json'
filename_path = /#{Rails.root.to_s}\/public\/(assets\/.*)/.match(File.absolute_path(asset))[1].to_s
# f.write("assets/#{File.basename(asset)}\n")
f.write(filename_path.concat("\n"))
end
end
f.write("\nNETWORK:\n")
f.write("*\n")
f.write("http://*\n")
f.write("https://*\n")
end
puts 'Done.'
end
namespace :deploy do
task :precompile_assets do
require 'fileutils'
if File.directory?("#{Rails.root.to_s}/public/assets")
FileUtils.rm_r "#{Rails.root.to_s}/public/assets"
end
puts 'Precompiling assets...'
puts `RAILS_ENV=production bundle exec rake assets:precompile`
puts 'Done.'
end
end
So when I run rake generate_appcache_file on the terminal, I got a /public/manifest.appcache file with the compiled assets like this:
CACHE MANIFEST
# Version 1409045103
CACHE:
assets/app/backgrounds/strips-05561384267a3286ab382c852f1e8b0d.jpg
assets/app/backgrounds/team-12e0fc5f670794c4eba3db117fba6746.jpg
assets/app-a7de6b02d1d39b783fe4e7ab7906ec95.css
assets/app-ae958853aa13f9011e35121cbe5b3cfe.js
NETWORK:
*
http://*
https://*
Finally, I call that file on my /app/views/layouts/app.html.erb file:
<!DOCTYPE html>
<html lang="en" manifest="/manifest.appcache">
More info about offline application cache that helps me a lot can be found here.
I have a whole lot of html files that live in one folder. I need to convert these to markdown I found a couple gems out there that does this great one by one.
my question is...
How can I loop though each file in the folder and run the command to convert these to md on a separate folder.
UPDATE
#!/usr/bin/ruby
root = 'C:/Doc'
inDir = File.join(root, '/input')
outDir = File.join(root, '/output')
extension = nil
fileName = nil
Dir.foreach(inDir) do |file|
# Dir.foreach will always show current and parent directories
if file == '.' or item == '..' then
next
end
# makes sure the current iteration is not a sub directory
if not File.directory?(file) then
extension = File.extname(file)
fileName = File.basename(file, extension)
end
# strips off the last string if it contains a period
if fileName[fileName.length - 1] == "." then
fileName = fileName[0..-1]
end
# this is where I got stuck
reverse_markdown File.join(inDir, fileName, '.html') > File.join(outDir, fileName, '.md')
Dir.glob(directory) {|f| ... } will loop through all files inside a directory. For example using the Redcarpet library you could do something like this:
require 'redcarpet'
markdown = Redcarpet::Markdown.new(Redcarpet::Render::HTML, :autolink => true)
Dir.glob('*.md') do |in_filename|
out_filename = File.join(File.dirname(in_filename), "#{File.basename(in_filename,'.*')}.html")
File.open(in_filename, 'r') do |in_file|
File.open(out_filename, 'w') do |out_file|
out_file.write markdown.render(in_file.read)
end
end
end
