I am reading the documentation for it but still can't quite figure out how to set it up.
So far I created a jsroutes.rb file and gem in the Gemfile and declaring it in application.js file.
But now how to use it? What to do with jsroutes.rb file? Can someone show me how to use this?

JS routes adds named routes to your javascript. you know how in view you can write new_blog_comment_path(#blog) and it automatically gives you /blogs/:blog_id/comments/new path? JS routes allows you to do same. So assuming you have blog and nested comments route, then you can use js-routes in your js: you can write Routes.new_blog_comment_path(blog_id_or_blog_json) and it will automatically generates string which is the path for that route.

I have added into application.rb string
config.paths['app/views'] << 'app/views/cabinet'
and created a view 'app/views/cabinet/index.html.slim'.
But when I go to route localhost:3000/manager/pages (It uses layout manager if it make sence), Rails gives the error
Manager::PagesController#index is missing a template for this request format and variant.
What I'm doing wrong?
I am not sure what you are trying to do by overriding the mapping for the location of app/views but it doesn't sound like a good idea to me.
Without knowing more about your code I would suggest you remove that config line from application.rb and simply use:
render 'cabinet/index'
from PagesController#index action.
Just wanted to know, what does this line mean in the routes.rb file:
AppName::Application.routes.draw do
Please explain. I am new to Rails.
Have a read through this page.
Basically, within the block passed to Application.routes.draw (which is just a call to a method defined in ActionDispatch::Routing module within the Rails core framework), you define all the URLs/Paths that you want your Rails application to respond to.
You can see all these route definitions, by running:
rake routes
in your terminal.
It is the main routes file which defines the root and other paths for the link.
It is used as suppose you want to change your index page from default ruby on rails to your index page you make changes to file and add
root to: "controllername#index"
This file is also used to add the model to the application
resources: "model_name"
Apart from this you can also define links in your rails application
get 'courses/index'
So going from courses controller to view of the index.
i'm using devise for authenticate the users in my rails app, i've exported the views by using the comand
rails generate devise:views
i see that the files have a 'blank style' so how i can do for apply to them a mine custom file css?
Add gem in your Gemfile
gem "twitter-bootstrap-rails"
visit link for reference
https://github.com/seyhunak/twitter-bootstrap-rails
http://getbootstrap.com
You can find the generated devise view files in app/views/devise.
Just add needed html elements/css classes the same way you would to other view files.
Keep in mind that this will use your default(application.html.erb) layout.
Probably not the best way, but it works and it's not too messy:
devise uses the global application.scss styles by default.
So I just create a login.scss, signup.scss, etc. in my route assets/stylesheets directory and the add #import "login.scss" at the end of application.scss.
Just make sure these page are imported after whatever global styles you want to make sure they inherit.
Note:
As my application expands I usually end up abstracting everything into distinct stylesheets so my application.scss ends up being a list of imports anyway.
I'm sure there are better ways to do this, but this was the "I'm just a designer and need this to work without overcomplicating things" way,
Installation
Add this line to your application's Gemfile:
gem 'devise-bootstrap-views'
And then execute:
$ bundle
Add some minor css fix to your rails asset pipeline manifest
SASS
*= require devise_bootstrap_views
LESS
*= require devise_bootstrap_views_less
rails g devise:views:bootstrap_templates

Is there a method like "full_url" such that #comment.full_url or full_url_for(#comment) returns "http://www.host.com/comments/id" where www.host.com is the default host domain and id is #comment.id. Or, if not, what would be an elegant way to generate this url string?
I'm pretty new at Rails, most of the methods I've learned insert the tag and other markup.
url_for is not helping because I can't do something like the following:
url_for(#comment, {:only_path => false})
I've spent way too much time trying to figure this out. It came down to either hacking or asking for the right way on SO. Here I am.
If you are setting up your routes correctly in your config/routes.rb file then you should have access to named routes in your controller and in your views. Which should mean that all you should need to do is:
comment_path(#comment)
Or for the full url
comment_url(#comment)
To see a list of all of the routes from the command line, you can type rake routes from the project root. Welcome to rails! Here is a good resource for rails 3 routing: http://guides.rubyonrails.org/routing.html
some additional resources via Railscasts:
http://railscasts.com/episodes/231-routing-walkthrough
http://railscasts.com/episodes/232-routing-walkthrough-part-2
My goal is to generate a directory of static html, javascript, and image files within my Rails (3) app, driven by ERB templates. For example, as a developer I might want to generate/update these files:
#{Rails.root}/public/products/baseball.html
#{Rails.root}/public/products/football.js
..from the following template files:
#{Rails.root}/product_templates/baseball.html.erb
#{Rails.root}/product_templates/football.js.erb
Ideally the templates would have access to my app's Rails environment (including URL helpers, view helpers, partials, etc.).
What's the latest and greatest way to accomplish this?
I experimented with a custom Rails generator, but found that I needed to write custom logic for skipping non-ERB files, substituting file names, etc. There must be a better way.
I'm not sure what you are trying to do exactly, that may help provide better answers, but here is some useful information:
You can call into erb directly, some information on that is here, which have probably already been doing:
http://www.ruby-doc.org/stdlib/libdoc/erb/rdoc/classes/ERB.html
For the list of template files an easy Dir.glob should be able to help find the specific files easily and loop through them:
http://ruby-doc.org/core/classes/Dir.html#M000629
The tricky part I wouldn't know how to advise you on is getting access to the helpers and other things Rails provides. The helpers that you write are just modules, so you could mix those in, something similar might be possible with the built-in rails helpers.
This is interesting and related but doesn't directly answer your question, since its uses the Liquid templating engine instead of ERB, but otherwise, it does some of the static site generation you are talking about:
https://github.com/mojombo/jekyll
This is how I accomplished something similar. It accepts source and destination directories, wipes out the destination, then processes the source directory, either ERB-processing files and placing them in the destination or simply copying them (in the case of on-ERB files). It would need to be modified to handle recursively processing a directory.
I invoke it from a rake task like so:
DirectoryGenerator.new.generate(Rails.root.join('src'), Rails.root.join('public', 'dest'))
class DirectoryGenerator
include Rails.application.routes.url_helpers
include ActionView::Helpers::TagHelper
default_url_options[:host] = 'www.example.com'
def generate(source, destination)
FileUtils.rmtree(destination)
FileUtils.mkdir_p(destination)
Dir.glob(File.join(source, '*')).each do |path|
pathname = Pathname.new(path)
if pathname.extname == '.erb'
File.open(destination.join(pathname.basename.sub(/\.erb$/, '')), 'w') do |file|
file.puts(ERB.new(File.read(path)).result(binding))
end
else
FileUtils.cp(pathname, File.join(destination, pathname.basename))
end
end
end
end
Have you looked into Rails templates?
http://m.onkey.org/rails-templates for instance..
Not sure what you are getting at exactly.. are you trying to generate client sites by providing a few parameters.. that the end goal?
