rake assets:precompile issue with JS and stylesheets files with similar name

Hi, 


I've got following two files with same names under javascripts and stylesheets directories as:
- app/assets/javascripts/test_vendor.js
- app/assets/stylesheets/test_vendor.scss

Essentially a JS and an stylesheet files with same name.

--------------------------------------------------------------

I want these files to be precompiled and served from public directory.
Thus I updated:
config.assets.precompile += %w(test_vendor.js test_vendor.scss)

----------------------------------------------------------------

I am running following task to pre-compile my assets in development:
"rake assets:precompile RAILS_ENV=development RAILS_GROUPS=assets --trace"

It generates assets/ folder inside my public directoy.
But I see only test_vendor.js and test_vendor.js.gz inside it
test_vendor.css is missing.

Please let me know, how to avoid/fix this issue.

Regards
Farukh D M

Skip index in array.each_with_index loop

Can anyone help me on how to skip index in ARRAY.each_with_index loop?

Please look at below case:

In a ARRAY.each_with_index loop, I would like increase the index by 10
whenever a condition is met.

arr is array of numbers from 0 to 50
arr.each_with_index do |x,i|
  if i % 10 == 0
    puts "#{x} at #{i}"
    i = i+10  //index increased by 10
  end
end

The output should be:
10 at 10
30 at 30
50 at 50

Thanks
Ajit

problem of respond_with working on nested resources

hi all:

    when using namespace or nested resources in routes.rb,such as "namespace :admin { resources :books }, we can use [:admin, <at> book] way to generate path. It works fine in form_for , but when I use it with respond_with in controller, I get problems. 
    The problem is when I put following code in controller:
      
        def create
          <at> book=Book.find(params[:id])
          <at> book.save
        respond_with[:admin, <at> book]
       end 

    if there are some problems and the <at> book is not saved, the function should render new action, hence we can get error messages, but now it render index action. and the log file said it got a error 302. if I replace 'respond_with [ :admin, <at> book]' with 'respond_with <at> book,:location=>admin_book_path( <at> book)", it works fine. 
    should we not use "[:admin, <at> book]" way with respond_with?

thanks

Is command line Rails also so slow on Linuxes as it is on Windows?

There is a lot of questions on Stackoverflow about how Rails is slow in
command line on Windows machines. I use Windows and know that it is
true. All Rake tasks, all rails commands are very slow. Especially
testing is slow. I can't test my code as I want because of it.

But some people in their answers say that command line Rails is slow
only on Windows. On Linuxes it is ok. But before I switch to some Linux
(Ubuntu maybe) I'd like to ask if it is true that Rails on Linux is
fast.

If you have an experience of using Rails on both platforms (Windows and
Ubuntu, or some other Linux) please tell me, is it really faster/much
faster or the same/almost the same?

Creating nested hash from nested active record results

Hello,
  I'm trying to find a very abstract and "one size fits all" for
converting nested active record results to nested hashes.   It's easy,
to do one level deep as such:

[code]
results_to_hash = Hash[ found_categories.map{ |c| [c.id, c.title]}]
[/code]

But, when I try to add another collection to the mix, it completely
borks and the results_to_hash only returns an empty hash IE:

[code]
results_to_hash = Hash[ found_categories.map{ |c| [c.id, c.title,
c.categories]}]
[/code]

Ultimately, I'd like it to be smart enough to detect if a model object
contains a collection (IE: object.class.reflect_on_all_associations),
and automatically convert those to hashes.

Any ideas?

Thanks,
Eric

better rails source code documentation?

I'm new to both ruby and rails, coming from lots of experience with other languages and frameworks, and I'm struck by how poor the rails source code documentation is. For example, I'm looking at activerecord-3.2.13/lib/active_record/connection_adapters/abstract/quoting.rb, which contains


      # Quotes the column value to help prevent
      # {SQL injection attacks}[http://en.wikipedia.org/wiki/SQL_injection].
      def quote(value, column = nil)

I understand that it's debatable whether or not an end-user should directly use this, but my googling finds that many end users do in fact use it ...

How should I go about finding the answer to questions like "What is the 'column' argument? When might I want to use it?". I.e., I hoped the comments near the method definition would help ... is there a Ruby Way to answer these kinds of questions?

Assuming my complaint about the lack of documentation is legitimate, what's being done to correct it? How can I help?

How to develop an authentication/authorization plugin that I can use for multiple projects

I am a newbie for RoR but I liked it so far. For the current project I
already developed an authenticaion page where the user will be
authenticated before and after login. I know that I will be doing more
projects on RoR in the coming weeks as well and I don't want to copy
paste my codes to enable authentication in my projects. How can I create
an authentication system where I can use it in multiple projects. Are
there any plugins already been developed?

 You should also consider that, the authentication system also be on
call (it should be listening everytime the user goes from one page to
another page by checking if s/he is authorized and also the session
haven't expired yet and so on.). That means I still need the
authentication/authorization system to be there even after login. And
how do I integrate it with other ruby projects I will be working on.  I
hope it makes sense.

The database where users will be authorized might be the same or
different based on the projects.

Thank you
