Am trying to implement pagination in ruby on rails.So I reference solution found here link by mmrobins .
I have tried will_paginate options and its working fine.
Now am trying to implement the second options which ajax pagination by following railcasts pagination with ajax. here is the source link
My Issues with Ajax Pagination:
I have configured all the steps as required but when I restart my server,it shows error undefine local variable or method config for main:Object (NameError)
I believe this error was caused by setting the following code at config/environment.rb
config.gem "mislav-will_paginate", :lib => "will_paginate", :source => "http://gems.github.com"
any idea on ow to resolve the issue. Am running ruby on rails version
Here is the screenshot of how I save that line of code above at config/environment.rb
Wrap your configuration code under 'Rails.application.configure do .. end' in development.rb
Rails.application.configure do
# your code here
config.gem "mislav-will_paginate", :lib => "will_paginate", :source => "http://gems.github.com"
end
The following is my problem I have Rspec installed started a project in it every-time I want to test something have to require_relative it now this wasn't a problem until I wanted to finally test my controllers and cant seem to get the functions get , post constantly getting undefined function error.
If I put my controller like this
RSpec.describe ApplicationController, :type => :controller do
end
I am receiving uninitialized constant ApplicationController (NameError) if i require relative the application controller like this require_relative '../../app/controllers/application_controller' I get uninitialized constant ActionController (NameError) .
Can't seem to catch where the problem might be here is my Gemfile also
gem "rspec-rails", :group => [:test, :development]
gem "rspec", :group => [:test, :development]
group :test do
gem "capybara"
gem "factory_girl_rails"
end
I have been browsing the internet for 2 hours now viewd at least 10 other stackoverflow questions tried everything but nothing seems to be working ...
Everywhere I check they say that I should only need to add require 'spec_helper' and it should work but its not.
I can copy my rails_helper file also if needed but its the standard what came with it when I ran rails generate rspec:install .
Your help is much appreciated I really need to fix this because I am running out of time.
As of rspec-rails 3 the auto generated spec_helper.rb is split into two parts: spec_helper.rb and rails_helper.rb
The idea is that you can have specs that don't need rails loaded (and so are fast to load) as well as specs that do need rails loaded
For ones that do need rails loaded, like your controller spec you need to do
require 'rails_helper'
At the top, instead of requiring spec_helper.
When running script commands like script/console I get the error message:
no such file to load -- thinking-sphinx
In my evironment.rb file I have:
config.gem 'thinking-sphinx', :version => '1.3.18', :require_as => 'thinking_sphinx'
In my rake file:
require 'thinking_sphinx/tasks'
I have following versions:
gem 1.3.7
ruby 1.8.7
Rails 2.3.8
My rake commands like rake ts:rebuild work fine!
Is there a way to get rid of the annoying error message?
Tnx!!!
ps: I also use RVM
It looks like Rails is trying to require the gem as "thinking-sphinx" rather than as "thinking_sphinx". You need to use :lib to specify the require path rather than :require_as IIRC.
config.gem 'thinking-sphinx', :version => '1.3.18', :lib => 'thinking_sphinx'
I just updated all my gems and I'm finding that I'm getting errors when trying to run Test::Unit tests. I'm getting the error copied below. That comes from creating new, empty Rails project, scaffolding a simple model, and running rake test.
Tried Googling "uninitialized constant" and TestResultFailureSupport. The only thing I found was this bug report from 2007.
I'm using OS X.
These are the gems that I updated right before the tests stopped working:
$ sudo gem outdated
Password:
RedCloth (4.2.1 < 4.2.2)
RubyInline (3.8.1 < 3.8.2)
ZenTest (4.1.1 < 4.1.3)
bluecloth (2.0.4 < 2.0.5)
capistrano (2.5.5 < 2.5.8)
haml (2.0.9 < 2.2.1)
hoe (2.2.0 < 2.3.2)
json (1.1.6 < 1.1.7)
mocha (0.9.5 < 0.9.7)
rest-client (1.0.2 < 1.0.3)
thoughtbot-factory_girl (1.2.1 < 1.2.2)
thoughtbot-shoulda (2.10.1 < 2.10.2)
Has anyone else seen this issue? Any troubleshooting suggestions?
UPDATE
On a hunch I downgraded ZenTest from 4.1.3 back to 4.1.1 and now everything works again.
Still curious to know if anyone else has seen this or has any interesting comments or insights.

This can happen if modules are declared in a single statement when the parent module they are nested inside has not yet been loaded. I haven't looked at the code in those gems, but my hunch is that's what is happening. Chuck's solution would suggest that. calling gem 'test-unit' first will load the parent module, so the setup of zen test ends up working ok.
e.g.
module Foo::Bar
def do_stuff
# insert awesomeness here...
end
end
Will result in an error if the parent Foo module hasn't already been defined (e.g. by another gem)
A safer way to declare this is
module Foo
module Bar
def do_stuff
# insert awesomeness here...
end
end
end
May be a bug in Zentest that needs patching.
This apparently comes from using Test::Unit 2.0 with the old Test::Unit. According to Kouhei Sutou on RubyForge, it can be fixed by calling gem 'test-unit' before you require 'test/unit'.
As this link suggests http://floehopper.lighthouseapp.com/projects/22289-mocha/tickets/50
it may happen due to preliminary initialization of mocha lib.
To prevent it from happeing it is advisable to add line
config.gem 'test-unit', :lib => 'test/unit'
to config/environment.rb
Here is the recipe for test_unit 2.0.7 on Rails 2.3.5:
In config/environments/test.rb:
config.gem 'test-unit', :version => '2.0.7', :lib => false
In test_helper.rb,
add require 'test/unit',
immediately after require 'test_help'
So it looks like this:
require 'test_help'
require 'test/unit'
If you receive this error:
%': one hash required (ArgumentError),
upgrade gem i18n to v0.3.6.
I was getting this without mocha or shoulda installed.
This post suggests it's due to an incompatibility in test-unit >= 2.0, which I installed as a dependency for the systools gems. Downgrading to 1.2.3 worked for me, a simple require might also.
Same issue with me too.
Nothing above mentioned worked for me except downgrading test-unit back to 1.2.3
I'm missing the coloring of the test-unit 2.x
Found the (ugly) solution:
gem 'unit/test'
must be called inside the tests too, not only in the Rakefile.
I ran into this today on Mac OS X 10.6. My solution is as follows:
config.gem 'test-unit', :lib => 'test/unit', :version => '1.2.3'
config.gem 'autotest'
config.gem 'cucumber'
config.gem 'cucumber-rails', :lib => false
config.gem 'ffaker', :lib => 'faker'
config.gem 'rspec', :lib => false, :version => '>= 1.2.0'
config.gem 'rspec-rails', :lib => false, :version => '>= 1.2.0'
config.gem 'selenium-client', :lib => 'selenium'
config.gem "thoughtbot-factory_girl", :lib => 'factory_girl', :source => "http://gems.github.com"
config.gem 'thoughtbot-shoulda', :lib => 'shoulda'
config.gem 'webrat'
config.gem 'ZenTest', :lib => 'zentest'
As with aronchick's comment, for me (OS X 10.6) solution was
sudo gem uninstall test-unit
all versions.
You get auto_test to work again with something like
RUBY="ruby -I.:lib:test -rubygems -e 'gem \"test-unit\"'" autotest
I am not a nuby to rails but I am still learning and hopefully always will be :-).
Rails 2.3 production environment using Ruby Enterprise Edition and passenger can produce a totally misleading useless error during startup (/var/log/passenger.log). Something like:
Exception NameError in PhusionPassenger::Rack::ApplicationSpawner (uninitialized constant XXX)
If you run script/console on the production server, you may see:
Loading production environment (Rails 2.3.4)
/home/ubuntu/MyApp/shared/bundle/ruby/1.8/gems/activesupport-2.3.4/lib/active_support/dependencies.rb:105:in const_missing:NameError: uninitialized constant XXX
This is happening to me in this instance only in production environment, not staging, not development. After a full day of research and experiments, I have concluded that in the production environment, REE or something must pre-load classes and the pre-loader apparently does not like to see classes being re-opened before they are created (an educated guess).
In app/models/calendar.rb:
Class Calendar < ActiveRecord::Base
# This defines the class
End
In app/models/event.rb
Class Event < ActiveRecord::Base
# This desined the class
End
Class Calendar
# This is supposed to 're-open' the Calendar class
has_many :events
end
The above generic sample code snippet can cause startup issue. I am not sure of the order that pre-loading classes takes place but I suspect that may be the issue. I moved the ‘has_many :events’ into the class definition in app/modeles/calendar.rb and my app now starts without error.
So, a good rule to follow is to put your Active Record Associations (has_many, belongs_to) inside the defining class (where the class is created).
If you add the following line to your environment.rb, or your config/environments/test.rb this should fix the issue
config.gem "test-unit", :lib => "test/unit", :version => ">=2.0.9", :env => "test"
I Believe you will need to add it before the mocha line if you use mocha.
I have a very simple controller:
require 'net/ssh'
class MyController < ApplicationController
def foo
render :text => 'bar'
end
end
But when I request http://server:3000/my/foo I get:
MissingSourceFile in MyController#foo
no such file to load -- net/ssh
The gem is installed
> gem list net-ssh
*** LOCAL GEMS ***
net-ssh (2.0.11)
Also, I tried require 'net/ssh' in IRB, and it works.
MyController works fine on Windows, but fail on Ubuntu.
What can be wrong?
In a project I am working on we have used the config/environment.rb file to hold the gem require stuff. So
Rails::Initializer.run do |config|
# ...
config.gem 'net-ssh'
config.gem 'daemons'
config.gem 'slave'
config.gem 'vpim'
config.gem 'json'
# ...
end
I think you will require 'net-ssh' rather than 'net/ssh'. However we did run into a problem where have a hyphen in the name of the gem led to failures. Then we had to do
config.gem 'Ruby-IRC', :lib => 'IRC'
so that version maybe required for you. So that would be
config.gem 'net-ssh', :lib => 'net/ssh'
in case of rails 3.0
this solution if OK.
add this in the yourapp/Gemfile,
gem 'net-ssh
This may help:
Rails Gem Dependencies and Plugin Errors
This is also worth watching:
Railscasts: Gem Dependencies
In my case, since it's a stand alone ruby app, I only needed to require rubygems.
You can also use Dr Nic's ''gemsonrails'' and load vendored gems as plugins, check:
http://gemsonrails.rubyforge.org
I think, the original problem was that I used normal user instead of root:
$ gem install net-ssh
WARNING: Installing to ~/.gem since /usr/lib/ruby/gems/1.8 and
/usr/bin aren't both writable.
WARNING: You don't have /home/alex/.gem/ruby/1.8/bin in your PATH,
gem executables will not run.
So, I guess, rails could not find this gem.
