For Rails you can create your own generators[1].
For other Ruby projects, I guess it depends on how you create your
files. If you're using some sort of IDE, it will depend on that,
otherwise, you;ll have to add it yourself.

Hope it helps.

Correct - ruby 1.9 added a json-ish alternative syntax for hash

[Rails] Why does this work?

[Jonathan Telfer]

I've been working through the Depot application to get back into Rails
after a few years doing other things. While I was looking at some
functional tests earlier I started thinking about this:

put :update, id: @user.to_param, user: @input_attributes

why doesn't the "id: @..." part throw an exception? id: isn't a
symbol. Is this some sort of alternative method of declaring a hash?
Is it a method call?

It works, which is great, but I'd love to know why.

[Zach S.]

I also ran into the same error after following the instructions when
following the instructions in Ruby on Rails Tutorial: Learn Rails by
Example http://ruby.railstutorial.org/chapters/beginning#top by
Michael Hartl.

The problem is that Heroku doesn't support the SQLite.

The solution is to convert your database to either MongoDB or
PostgreSQL.  The instructions can be found at

Re: [Rails] Ruby adoption statistics

[Kevin Bedell]

Specifically to address Ruby being a dying language:


I find ohloh.net to be a great source of information on topics like this.

  http://www.ohloh.net/p/ruby

  Ruby:

 Source tree:
 http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/

  - Is approaching 1 million lines of code and growing.
  - Has had 46 developers commit code over the last year: "This is one of
the largest open-source teams in the world, and is in the top 2% of all
project teams on Ohloh."
   - Is the main language for many other innovative new applications and
libraries including rails, rubygems, rake, rspec, cucumber, redmine,
capistrano, haml, and many others. (See
http://www.ohloh.net/p?sort=users&q=language%3Aruby )

Anyway, this is just a quick scrape of some stats. There's much more if you
dig around there and other places.

Re: [Rails] Ruby adoption statistics

Hi Andrew,

> Do you know where I can find articles/statistics on Ruby adoption

It's going to be difficult to get good data.  The biggest reason,
IMHO, is that companies that do adopt RoR are going to be doing so for
the productivity.  If it works, they're not going to talk about it.
That's what 'strategic advantages' are all about.  Keep your mouth
shut and hope your competitors don't figure it out.

If you're convinced that you need hard data then I'd recommend looking
for secondary indicators: growth of hosting providers is one.  How
many are there today vs. 2 years ago.  Do they say anything about
customer base?  What about financial condition?  There are tertiary
indicators as well.  Of those hosting providers, how many moved into
new digs this year?  They moving up?  Or scaling back?  I doubt very
seriously that the leg-work will pay off (see below for why) but it
would be an interesting exercise.  If you do undertake it, I'm sure
you'll be able to find a publisher who'll pay you a small amount (way
out of proportion if you do the per-hour calculation, so don't ;-) )
to publish it.

> and how I can convince my co-worker(s) that Ruby is the way to go?

You probably can't 'convince' them.  The choice isn't so much rational
as it is personal preference.  There are, IME, two ends to the
programmer-preference spectrum:  Java and Rails.

The spectrum is most easily characterized by the individual's
tolerance for delay in the gratification / feedback loop.  I liken the
Java end to the guys who build the huge, elaborate domino knock-down
displays.  Please understand that I am not criticizing at all; simply
making an observation on human nature.  The domino guys get a big dose
of gratification when the dominoes all fall.  But it's not about the
dominoes falling.  It's about the validation that all the setup steps
were done perfectly.  It's the validation that counts.  If the
dominoes all fell because the ground shook, there'd be no joy.

So if I were you (embarked on organizational change) I'd ignore the
developers who've already expressed a preference for Java.  Focus on
the ones that may be more attracted to a rapid-feedback model.
Introduce them gently; perhaps via your local ruby brigade.  Get them
around some folks who are clearly having more fun than them.  In any
event, they'll get some free pizza ;-)

Good luck and best regards,
Bill

[Rails] Ruby adoption statistics

[Andrew]

Hello,

I work for a company that uses PHP. In my free time I write Ruby apps. My 
manager recently "discovered" Heroku (which I had been using for a while) 
which spawned a discussion about eventually switching languages to start 
doing Ruby development (which would be awesome for me). However, my 
co-worker mentioned that he thinks if we are switching, we should switch to 
Java because Ruby is a dying language.

I just about fell out of my seat. *Dying* language? Far from it! Every 
company I know is deploying Ruby applications!

However, I don't have any stats to support this. I only have my experience 
and love of the language to base my opinions on. Do you know where I can 
find articles/statistics on Ruby adoption and how I can convince my 
co-worker(s) that Ruby is the way to go?

Thanks,
Andrew

Re: [Rails] Errors while installing sqlite3 for Rails

[Ruby Student]

Leonardo,

Yes, the executable are on my path. However, you suggested to type *node*,
which was the only one I had not installed.
I downloaded and built *node* and now I am past that issue.

However, NOW I have other issues. This is like pulling teeth. If I did not
want to learn Rails so badly, I would drop this altogether.

This is what I am getting now:

That's not Rails specific. You need to setup your Apache server to use SSL.
I'm not an Apache expert, but I think you have to:
- Enable mod_ssl
- Setup the port SSL will listen to (The default might be commented on
your conf file)
- Define your virtualhost for that port.

If your server already has SSL configured, you only need to define your vhost.

Hope it helps.

However, it looks like Rails is still looking for more dependencies, which I
already installed, except that I hit one which I can't see how to address
it.
The execjs wants a javascript runtime. I installed at least three suggested
ones:

ExecJS supports these runtimes:

   - therubyracer  - Google V8
   embedded within Ruby
   - therubyrhino  - Mozilla Rhino
   embedded within JRuby
   - Johnson  - Mozilla SpiderMonkey
   embedded within Ruby
   - Mustang  - Mustang V8 embedded
   within Ruby
   - Node.js 


 and I am still having the same error messages, which I am posting below.

I am truly sorry to bother you but I hit a wall. Also, I am not sure why
Rails does not load everything it needs. It already loads a large number of
pre-reqs.

Thank you

[Rails] Recommended SOAP library

[Leonardo Mateo]

Hi guys,
I have to deal with SOAP web services.
I've been googleing around a bit, and I can see 3 major topics: Savon,
 'soap/wsdlDriver and SOAP4R.

All points that Savon is the one, but I just wanted to be sure.
Does anyone have any tip on this?

Thanks a lot in advance.

Re: [Rails] Re: API request with email in address path possible?

[Martin Wawrusch]

It might be possible to pass it as part of the uri, but you do not want to
do that because it would create a second url representing the same resource.
Basically, you want to have one url per resource to make the API easy to
use, and for things that are actually queries it is better to use
parameters.

Here is a simple example to illustrate the problem by adding voting to the
user resource:

/users/1/votes
/users/email/mar...@wawrusch.com/votes

Which one is the correct one? Software developers would guess the first one,
but machines would be clueless. And you would have to implement both routes
to be consistent, then you would have to document it, and then you would
hate programming :)

Re: [Rails] API request with email in address path possible?

[Martin Wawrusch]

Interesting question. First of all I think you need to change this a bit
into

/api/users/1 as the canonical url

and perhaps add a route like /api/users/search?email=youremail
which redirects to the canonical url.

[Rails] [ANN] Rails 3.1.1 has been released!

[Santiago Pastorino]

Hi everyone,

Rails 3.1.1 has been released.

## CHANGES

*ActionMailer*

* No changes


*ActionPack*

* stylesheet_link_tag('/stylesheets/application') and similar helpers doesn't
throw Sprockets::FileOutsidePaths exception anymore [Santiago Pastorino]

* Ensure default_asset_host_protocol is respected, closes #2980. [José Valim]

  Changing rake db:schema:dump to run :environment as well as :load_config,
  as running :load_config alone will lead to the dumper being run without
  including extensions such as those included in foreigner and
  spatial_adapter.

  This reverses a change made here:
  
https://github.com/rails/rails/commit/5df72a238e9fcb18daf6ab6e6dc9051c9106d7bb#L0L324

  I'm assuming here that :load_config needs to be invoked
  separately from :environment, as it is elsewhere in the
  file for db operations, if not the alternative is to go
  back to "task :dump => :environment do".

  [Ben Woosley]

* Update to rack-cache 1.1.

  Versions prior to 1.1 delete the If-Modified-Since and If-Not-Modified
  headers when config.action_controller.perform_caching is true. This has two
  problems:
* unexpected inconsistent behaviour between development &
  production environments
* breaks applications that use of these headers

  [Brendan Ribera]

* Ensure that enhancements to assets:precompile task are only run once
[Sam Pohlenz]

* TestCase should respect the view_assigns API instead of pulling variables on
its own. [José Valim]

* javascript_path and stylesheet_path now refer to /assets if asset pipelining
is on. [Santiago Pastorino]

* button_to support form option. Now you're able to pass for example
'data-type' => 'json'. [ihower]

* image_path and image_tag should use /assets if asset pipelining is turned
on. Closes #3126 [Santiago Pastorino and christos]

* Avoid use of existing precompiled assets during rake assets:precompile run.
Closes #3119 [Guillermo Iguaran]

* Copy assets to nondigested filenames too [Santiago Pastorino]

* Give precedence to `config.digest = false` over the existence of
manifest.yml asset digests [christos]

* escape options for the stylesheet_link_tag method [Alexey Vakhov]

* Re-launch assets:precompile task using (Rake.)ruby instead of Kernel.exec so
it works on Windows [cablegram]

* env var passed to process shouldn't be modified in process method. [Santiago
Pastorino]

* `rake assets:precompile` loads the application but does not initialize
it.

  To the app developer, this means configuration add in
config/initializers/* will not be executed.

  Plugins developers need to special case their initializers that are
  meant to be run in the assets group by adding :group => :assets. [José Valim]

* Sprockets uses config.assets.prefix for asset_path [asee]

* FileStore key_file_path properly limit filenames to 255 characters.
[phuibonhoa]

* Fix Hash#to_query edge case with html_safe strings. [brainopia]

* Allow asset tag helper methods to accept :digest => false option in
order to completely avoid the digest generation.
Useful for linking assets from static html files or from emails when the user
could probably look at an older html email with an older asset.
[Santiago Pastorino]

* Don't mount Sprockets server at config.assets.prefix if
config.assets.compile is false. [Mark J. Titorenko]

* Set relative url root in assets when controller isn't available for
Sprockets (eg. Sass files using asset_path). Fixes #2435 [Guillermo
Iguaran]

* Fix basic auth credential generation to not make newlines. GH #2882

* Fixed the behavior of asset pipeline when config.assets.digest and
config.assets.compile are false and requested asset isn't precompiled.
  Before the requested asset were compiled anyway ignoring that the
config.assets.compile flag is false. [Guillermo Iguaran]

* CookieJar is now Enumerable. Fixes #2795

* Fixed AssetNotPrecompiled error raised when rake assets:precompile
is compiling certain .erb files. See GH #2763 #2765 #2805 [Guillermo
Iguaran]

* Manifest is correctly placed in assets path when default assets
prefix is changed. Fixes #2776 [Guillermo Iguaran]

* Fixed stylesheet_link_tag and javascript_include_tag to respect
additional options passed by the users when debug is on. [Guillermo
Iguaran]

* Fix ActiveRecord#exists? when passsed a nil value

* Fix assert_select_email to work on multipart and non-multipart
emails as the method stopped working correctly in Rails 3.x due to
changes in the new mail gem.


*ActiveModel*

* Remove hard dependency on bcrypt-ruby to avoid make ActiveModel
dependent on a binary library.
  You must add the gem explicitly to your Gemfile if you want use
ActiveModel::SecurePassword:

  gem 'bcrypt-ruby', '~> 3.0.0'

  See GH #2687. [Guillermo Iguaran]


*ActiveRecord*

* Add deprecation for the preload_associations method. Fixes #3022.

  [Jon Leighton]

* Don't require a DB connection when loading a model that uses
set_primary_key. GH #2807.

  [Jon Leighton]

* Fix using select() with a habtm associati

[Rails] API request with email in address path possible?

[Heinz Strunk]

Hey,

I'm currently implementing a API for a website which is supposed to
support following requests:
/api/users/id/1
/api/users/email/t...@example.org
...

Of course the email address with its dot causes an error because if the
.org which is interpreted as file format.

How can I pass an email address like that?

Thanks for the help,
Hans

One can only forget things one has learned in the past. I'll stick to
postgres-pr for now, it is recommended in several places on the web
and so far seems to work without trouble.

[Rails] Re: Postgresql adapter not working

[Luís de Sousa]

Hi Peter,

That not exactly the same issue, I'd say an authoritative install
guide for Ubuntu is definitely needed, especially since a direct
install from the repositories won't work.

I used this guide which got Rails and Ruby to work on Ubuntu 10.10 64-
bit:

http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/

Though it installed the pg adapter instead of the postgres-pr gem.

Yeah - they are $0 to get started, then you pay to increase
bandwidth/throughput. I am not sure how it goes if you start getting a lot
of volume in terms of how the cost of heroku compares to others, but for the
sheer ease and slickness of easy deployments, creating multiple environments
(such as staging vs production), automated backups available (at least for
pg), and so much more, unless someone has a specific reason not to use them,
heroku is amazing. I hope their model is the general wave of the future, at
least for us who would rather create functionality than configure boxes.

First off, it's a bit odd to be making those calls to restclient where
you're making them - they'll happen when the class gets loaded, which
isn't really under your control.

Secondly you don't seem to be using ruby's interpolation properly -
API_URL isn't getting replaced by the value of that constant

Lastly, @ is a special character in a url (since it marks the
separation between the end of the password and the rest of the url),
so you'll need to escape the literal @ in your username (I'd be
surprised if there wasn't a way in rest client to just supply a
username and password rather than have to do that mangling yourself)

Is that supposed to be an answer to one of the questions previously
asked?  You have given no indication of which one, nor have you
answered some other questions.

Please reply again to whichever post you are replying and insert your
message inline at appropriate points in the previous post so that we
can see what you are replying to.

[Rails] 403 Error Dont know whats wrong.

[Kaushalya K.]

Hi,

I am quite new to ruby and am programming an application to send sms
using rest_client gem. I so far have code on one of my modules which
tries to send an sms to a number. It gives the 403 error -

RestClient::Forbidden in SMSController#index

403 Forbidden
Rails.root: /Users/user1/Desktop/rails_projects/sms_app

My code in the module looks as follows - before adding this code i had a
simple enter number and enter message text boxes with the usual
edit/add/delete options.

require 'rubygems'
require 'rest_client'

class SMS < ActiveRecord::Base

  API_URL = 'http://services..com/SMS'
  API_KEY = '0'
  RestClient.post 'API_URL/TXT//07996750812/wakeup/API_KEY',
:number => '079945460812', :nested => { :message => 'working   from
inside' }
RestClient.get 'https://y...@gmail.com:password@API_URL'
end

My user name is in the form of an email. let me what you think the
problem would be. thanks :)
