[Rails] Re: what is mean of Deployment?

[Mohamed Aslam]

All most all developers develop application in their local computer.
This is called as development environment. Once your development
completed, you need to move the application to a production server
where other people can use your website. Moving the application from
development environment to production servers called deployment.

Hope you understand.

[Rails] rubygems fail - require hpricot!

[Anush J.]

Hi guys,
I wanted to fetch some info from webpage and use it in my db. I read
hpricot is one way to do it. But the problem is I'm unable to use it
with my app. For some reason after successfully installing hpricot it
fails when I try to use it in the rails console.

I've been trying to fix this for the last four-five days. I'm stumped !
I tried re-installing everything and still cant go past the error. Can
some one please help me, I really appreciate it !

I have put down all the info below, I'm running mac os - snow leopard. I
see the same problem on centOS 5.5 too :(

[Rails] rspec-2.6.0.rc2 is released!

[David Chelimsky]

We're releasing rspec-2.6.0.rc2 as a release candidate as there are some 
internal changes that we'd like to see put through their paces before doing a 
final release. Note that the changes I speak of are internal. There are no new 
deprecations in this release, nor any backward-incompatible changes.

There are, however, some new features that we're really excited about. Please 
do check it out and please do report any issues to the appropriate github issue 
tracker:

* [rspec-core](http://github.com/rspec/rspec-core/issues)
* [rspec-expectations](http://github.com/rspec/rspec-expectations/issues)
* [rspec-mocks](http://github.com/rspec/rspec-mocks/issues)
* [rspec-rails](http://github.com/rspec/rspec-rails/issues)

### rspec-core-2.6.0.rc2

[full changelog](http://github.com/rspec/rspec-core/compare/v2.5.1...v2.6.1.rc2)

* Enhancements
  * `shared_context` (Damian Nurzynski)
  * extend groups matching specific metadata with:
  * method definitions
  * subject declarations
  * let/let! declarations
  * etc (anything you can do in a group)
  * `its([:key])` works for any subject with #[]. (Peter Jaros)
  * `treat_symbols_as_metadata_keys_with_true_values` (Myron Marston)
  * Print a deprecation warning when you configure RSpec after defining
an example.  All configuration should happen before any examples are
defined. (Myron Marston)
  * Pass the exit status of a DRb run to the invoking process. This causes
specs run via DRb to not just return true or false. (Ilkka Laukkanen)
  * Refactoring of ConfigurationOptions#parse_options (Rodrigo Rosenfeld Rosas)
  * Report excluded filters in runner output (tip from andyl)

* Bug fixes
  * Don't stumble over an exception without a message (Hans Hasselberg)
  * Remove non-ascii characters from comments that were choking rcov (Geoffrey
Byers)
  * Fixed backtrace so it doesn't include lines from before the autorun at_exit
hook (Myron Marston)
  * Include RSpec::Matchers when first example group is defined, rather
than just before running the examples.  This works around an obscure
bug in ruby 1.9 that can cause infinite recursion. (Myron Marston)
  * Don't send example_group_[started|finished] to formatters for empty groups.
  * Get specs passing on jruby (Sidu Ponnappa)
  * Fix bug where mixing nested groups and outer-level examples gave
unpredictable :line_number behavior (Artur Małecki)
  * Regexp.escape the argument to --example (tip from Elliot Winkler)
  * Correctly pass/fail pending block with message expectations

### rspec-expectations-2.6.0.rc2

[full 
changelog](http://github.com/rspec/rspec-expectations/compare/v2.5.0...v2.6.1.rc2)

* Enhancments
  * `change` matcher accepts Regexps (Robert Davis)
  * better descriptions for have_xxx matchers (Magnus Bergmark)

* Bug fixes
  * Removed non-ascii characters that were choking rcov (Geoffrey Byers)
  * change matcher dups arrays and hashes so their before/after states can be
compared correctly.
  * Fix the order of inclusion of RSpec::Matchers in
Test::Unit::TestCase and MiniTest::Unit::TestCase to prevent a
SystemStackError (Myron Marston)


### rspec-mocks-2.6.0.rc2

[full 
changelog](http://github.com/rspec/rspec-mocks/compare/v2.5.0...v2.6.1.rc2)

* Enhancements
  * Add support for any_instance.stub and any_instance.should_receive (Sidu
Ponnappa and Andy Lindeman)

* Bug fixes
  * fix bug in which multiple chains with shared messages ending in hashes
failed to return the correct value

### rspec-rails-2.6.0.rc2

[full 
changelog](http://github.com/rspec/rspec-rails/compare/v2.5.0...v2.6.1.rc2)

* Enhancments
  * rails 3 shortcuts for routing specs (Joe Fiorini)
  * support nested resources in generators (Tim McEwan)
  * require 'rspec/rails/mocks' to use `mock_model` without requiring the whole
rails framework

* Bug fixes
  * fix typo in "rake spec:statsetup" (Curtis Schofield)
  * expose named routes in anonymous controller specs (Andy Lindeman)
  * error when generating namespaced scaffold resources (Andy Lindeman)

[Rails] Re: Problem with resque; parent process doesn't die

[Nilesh]

What if I explicitly exit process(using Process.exit(0)) in FooJob#perform 
after line Bar.add_jobs?

[Rails] Problem with resque; parent process doesn't die

[Nilesh]

 

I am facing problem in resque process. I have following implementation:

/config/resque_schedule.yml

add_jobs_to_queue:
  cron: "15 * * * *"
  class: FooJob
  description: "Find results from class Bar and put on queue"

/app/jobs/foo_job.rb

class FooJob
  @queue = :normal

  def self.perform
Bar.add_jobs
  end
end

app/models/bar.rb

class Bar
  def self.add_jobs
students = find :all
students.each { |student| student.enqueue(:asap) }
  end
end

Here FooJob(queue: normal) is executed using resque scheduler. The 
performmethod in FooJob calls method 
add_jobs from class Bar. In this method, results are found, and put one by 
one on queue asap. So FooJob becomes parent process, and execution of 
'student' becomes child process. So there should be 2 running processes in 
the system when this executes. When execution overs, both processes should 
die automatically. My problem is, the parent process doesn't die though 
child process has finished execution.

'ps aux | grep resque' shows following result on my machine:

root 7205  0.0  0.7 228012 122920 ? Ss Apr13 0:21 resque-1.13.0: Forked 12933 
at 1302843615

Here it states that process 7205 has forked process 12933, but I don't see 
process 12933 running in the system(means it has finished execution)

What should be problem with parent process doesn't die? What is solution on 
this?

Thanks in advance.

This totally fixed the problem and my app is now properly doing Solr
full text searches of my jobs model. Thank you for the assistance.

Just in case it helps; if you have a current_user helper, you don't need to
assign anything to @user in a controller at all. You can just use
current_user in your view. :-)

Aha! I've figured it out.

In case anyone else is wondering, I have a current_user defined in

current_user!

[Rails] Re: calling methods from one object in another?

[Nathan Domier]

I wanted to pass it the id of the logged in user.  I have some things 
that I want to show up for some users and not for others.  I wanted to 
use @user.admin? for this, which works fine on the users pages. 
however, since I can't get the @user assignment to work for pages this 
isn't working either :(

Also by default if you'd created the app as a MySQL app in the first place:
  encoding: utf8
  reconnect: false
  socket: /var/run/mysqld/mysqld.sock

HTH.

[Rails] Rails 3 render erb text

[Andrew Miehs]

Hi all,

I have a file called configure.text.erb in views// directory.

Why does 
render 'configure.text.erb' 
actually work?

How does render know that this is plain text? Does it assume this due to the 
text.erb ending?

How does this actually all plumb together?

And would be the difference in the between using the following two to generate 
html in a controller?
Am I correct in assuming that the first one will only generate html if asked 
for, the other will generate it all the time?
Does something in format.html call "render" ?

respond_to do |format|
  format.html # configure.html.erb
end

and using 

render 'configure.html.erb' 

Rails does a whole lot of great things, but at the moment the magic is 
overwhelming me.
Trying to work out how all this is connected is really confusing.


Thanks for any light you can shed on this.


Best regards,


Andrew

[Rails] handling validation

[Matt Harrison]

Hi list,

I've started migrating to rails 3 and right now I'm getting to grips with the
different methods for handling validation error message.

I've found this on asciiguides which seems good, the first code examples which 
move
the error display handling to a partial:

http://asciicasts.com/episodes/211-validations-in-rails-3

Which works perfectly for the new and create actions, however on the edit and 
update
actions it gives me the following, referring to the first line of the partial:

undefined local variable or method `target' for 
#<#:0xb645683c>

The only difference between the new/create and the edit/update actions is the 
formers
uses @model.save and the latter @model.update_attributes.

If I take out the refence to the partial, replacing the model name back in, 
everything
works fine but really isn't DRY.

I can post full code examples if necessary.

Thanks

Matt

[Rails] Problem with new action 'validate'

[Jose tomas R.]

I've created a new action in my invitations controller named
validate and validation

controller/invitations_controller.rb

def validate
end

def validation
  @invitation = Invitation.find(params(:key))

  if @invitation != nil
  redirect_to new_client_path, :notice => 'Codigo Aceptado'
  else
  flash.now[:alert] = 'Ingrese un codigo valido'
  render :action => 'validate'
  end
   end

_validation_form.html.erb

<%= form_tag invitations_validate_path do %>
  
<%= label_tag :key %>
<%= text_field_tag :key %>
  
  
<%= submit_tag 'validate', :action => 'validation' %>
  
<% end %>

So when I enter a valid key I get redirected to create a user, but this
isn't working. the submit isnt doing anything, the :action => validation
is not working

config/routes.rb

resources :invitations do
  collection do
get :validate
get :validation
  end
end

I assume you mean <%= in the second case. The way that erb generates
ruby code from a template means that comments aren't supported - the
comment inside the <% tag ends up commenting other bits of the code
generated by erb.
The only form of comments that are safe is <%#

What's invalid about it? I assume you get some sort of error
message... can you post that to enlighten us, please?

Personally, though, I find I get problems with Ruby parsing if I
comment in ERB tags after code, instead I tend to do this if I
desperately want to comment in a view:
<% code here %><%# comment here %>

[Rails] Adding composite index to pre-existent table

[Federico]

Hello everybody,
I'm a newbie in RoR.
In order to create a table I've created a migration with the 'rails
generate model...' command.
Now I would like to add a composite index over two columns of this
table with another, new, migration.
Is it possible?
I've read the documentation about the add_index transformation but I
can't create the new migration from command line.
I think I can edit the 'create table' migration file, but I would like
to have a different migration (generated by 'rails' command).

Thanks in advance for your help,

Federico

[Rails] Assigning admin invalidates the user

[non useless]

I am experiencing an issue as I am following the tutorial and
currently at the end of chapter 10. When I use toggle in the rails
console to flip the admin property of a user from false to true (I'm
trying to create an Admin user), I am successful in doing so, however
that user becomes invalid, when I try to log in to the application
with this user's credential I am getting an error that the credentials
are incorrect (even though they are) ... just from checking the logs
and the looking at the terminal, it seems the authenticity token is
either missing or incorrect... any ideas what I am doing wrong here? I
tried following the tutorial as close as possible, I doubt I missed
something, but its obviously possible..

Thank you and best regards!

[Rails] Integrating the fb_graph or koala gem with devise+mongoid+omniauth in rails 3

[Andy S]

I need Facebook API integration in my rails application, but I can't
figure out how to store the Facebook access token from Omniauth so
that it can be reused later by a Facebook API gem. The Facebook API
gems I am considering is fb_graph or koala (don't really care which),
but I am open to other solutions if there are better alternatives.

A question on Stackoverflow provides a solution which the questioner
(and I) were not able to get to work:
  
http://stackoverflow.com/questions/4010915/does-omniauth-provide-simple-hooks-to-the-facebook-graph-api

The base code I want to integrate fb_graph or koala into comes from
the official devise example page:
  https://github.com/plataformatec/devise/wiki/Example-Applications
The base I am using integrates devise+mongoid+omniauth:
   https://github.com/fertapric/rails3-mongoid-devise-omniauth.git

Any tips on how to integrate fb_graph or koala (or any other facebook
API connection) with this devise+mongoid+omniauth base would be
greatly appreciated.

Best,
Andy

[Rails] newbie: to_json only/except + association confusion

[der_tom]

hi,

i want to return to_json with 'only' and also filtered.so i tried
various ways, but none of them are really good:

A)#OK , but filter missing
  format.json  { render :json => @project.to_json(:only =>
[:title ], :include=> { :tasks => {:only=>[:id,:title] } }  )  }

B)#Not OK > filter does not work,
  format.json  { render :json => @project.to_json(:only =>
[:title ], :include=> { :tasks => {:only=>[:id,:title] },, :conditions
=> ['tasks.is_enabled = ?', 1] }  )  }

C) #Not OK > works, but cant use only/except
  format.json  { render :json => @project.to_json(:only =>
[:title ], :method=> get_enabled_tasks  )  }

def get_enabled_tasks
  tasks.where("is_enabled = ?", 1)


D)#OK, but json output not nice
  format.json  { render :json => @project.to_json(:only =>
[:title ], :method=> get_enabled_tasks  )  }

def get_enabled_tasks
  ActiveRecord::Base.connection.execute(sql)
>>
"project":{"title":"testprojecttitle","get_enabled_tasks":
[["tasktitle","user1","1.1.2011"]]}}



>> so, how can i get filtered associations in a to_json call so that i actually 
>> get goodlookin json?


thx

If you're running Rails 3, you're better off using "mysql2" as the  
adapter and you have to make sure you include the mysql2 gem in your  
Gemfile too. Also, you might want to use a more secure password for  
MySQL on your production server ;-)

[Rails] Re: Error: uninitialized constant MysqlCompat::MysqlRes

[Tianchen J.]

After wrestling with this problem for several days I finally got it
nailed. 2 things that I have done that made it work:

   1. sudo env ARCHFLAGS="-arch x86_64" gem install --no-rdoc --no-ri
mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
   2. export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH"


I'm on Snow Leopard, and have only 1 MySQL (x86_64) 5.5, and 1 ruby
(prepackaged with Snow Leopard) installed.

[Rails] Basic crud pages for STI models

[Perry Smith]

If you have a model that is using single table inheritance, the simple
new, create, edit, and update methods and views might not do what you
want them to do.  I have an ActiveRecord::Base with just a name and a
type so I can define a Team (type) of "account" and a Dept of Education.
But suppose I misspell Education and I want to edit it.  What happens is
the edit method finds the record and makes it into a Dept (type or
class).  This confuses the form_for(@name) into producing URLs for Dept
which in my case isn't want I wanted.  I wanted to edit the entry as a
name.  (In my case, I don't have URLs and controllers for Team or Dept,
etc.)

The solution was to us becomes(klass) so the edit method becomes:

  def edit
@name = Name.find(params[:id]).becomes(Name)
  end

I did that same thing after all of the calls to find **in this case**.
There are probably 99% of the time that you want find to change the
instance into the proper class but if you don't, this is a simple way to
cast it back to the parent class.

As far as the above is concerned, map.root tells the route for the root i.e.
localhost:3000 in development or www.domain.com in production.

   I added the  *map.root :controller => "home"* at the bottom of
router.rb file and it worked.so i could accessed now "localhost:3000/
home/index

 Please  explain how it (*map.root :controller => "home"*)  is
working (means which part calls to which).

Re: [Rails] Re: what is mean of Deployment?

[Chris Kottom]

In a strict operational sense, the term means installation and
configuration/activation of software on any environment under management, so
it could be meant as production, staging, integration testing, etc.  In the
Rails world where development and testing are most often virtual
environments coexisting on the developer's workstation, this will only be
the production environment for most cases.

Also verify that you are _actually_ using Rails 2.3.8.  Very basic check, I
know, but routing syntax is different in Rails 3, and I don't believe older

It is generally not only that as the machine that will be running the
app in production is generally not the same one used for development.
So deployment is the whole operation of getting it up and running on
the production machine, which is often a public webserver rather than
a desktop machine so the software environment is often significantly
different.

I vaguely remember a ticket on the rails bug tracker about this. I
don't remember what the resolution was.

[Rails] Ruby On Rails 3 and Webrick

[kdwill]

Hi,

Thanks for taking a look at this.

I started a beginner's tutorial on RoR through lynda.com. I followed
the instructions to the letter. Everything was working so far until I
got to accessing Webrick. When I typed in "rails server" to begin
work, I got this error message below.

I'm using a

 - iMac
 - Ruby 1.87
 - Gem 1.7.2

I have been exposed to very little Rails and looking to learn how to
fix this. Your help would be greatly appreciated.

Thanks in advance for your attention and help if possible.

Your show action will usually be supplied with a :id parameter (since
show usually means show me this particular user) via the url (eg /
users/123) or query parameters.
On the other hand it sounds like when you link to your home action in
the pages controller you're not supplying an id parameter, and so
params[:id] is nil, so User.find(params[:id]) can't work.
Which user did you want to show?
