Delayed_job(2.1.4) + Rails(3.0.10) undefined method `delay' - ruby-on-rails-3

I upgrading a rails application to rails(3.0.10) and update the gem delayed_job. I updated my migration for the table delayed_job but unfortunatly the method ".delay" doesn't work.
NoMethodError: undefined method `delay' for #<User:0x10394d140>
I didn't find a solution for that. I did : "bundle install", I restarted the server, tried to instal as plugin...
Do you have any ideas?
Thanks.
UPDATE :
I fixed the problem but created a file config/initializer/delayed_job.rb with
require 'delayed_job'
Delayed::Worker.backend = :active_record

Sometimes gems just refuse to install properly. I think what you should do is (assuming you have git installed, otherwise go here https://github.com/tobi/delayed_job and download delayed_job as a zip file)
git clone https://github.com/tobi/delayed_job.git
take what he has in his lib folder and put it in yours. wherever you need to use his methods then do
require 'delayed_job'
in the top of those files
I checked this tutorial, it shows a way to setup in rails 3
http://www.dixis.com/?p=335
it suggests using this in your gemfile
gem "delayed_job", :git => 'git://github.com/collectiveidea/delayed_job.git'
(if it doesn't work with this either, then try the same thing that i did, but replace
git clone https://github.com/tobi/delayed_job.git
with
git clone https://github.com/collectiveidea/delayed_job.git
tell me if anything works

rvm using /after_cd_bunlder vs --binstubs. How are these different?

How are the outcome of these two methods different? Why use one over the other? I believe they both end up enabling you to issue 'rake' or 'rspec' without the preceeding 'bundle exec". My guess - with method 1 you only have to do this once, and then on ALL new rails project for the rvm ruby version will automatically have the desired feature ( as explained above)?
Method 1:
rvm get head && rvm reload
chmod +x $rvm_path/hooks/after_cd_bundler
bundle install --binstubs
OR
Method 2:
bundle install --binstubs
If found this documentation, but it did not help me understand which method to use. I looked on http://rvm.io and found intergration/bundler and /workflow/hooks.
The is code for after_cd_bundler (but I cannot post anymore links due to stackoverflow.com limitations on me)
This are not two different methods, this is one method and it is described in more detail here: http://robots.thoughtbot.com/post/15346721484/use-bundlers-binstubs
If you are using RVM then you do not need any of this, using --binstubs requires adding to PATH - which is big security risk if used from project directory, RVM comes with rubygems-bundler gem preinstalled which does the automatic loading of bundler (no need for bundle exec), you can find more details about the gem here: https://github.com/mpapis/rubygems-bundler#readme

Rails 3.2.11 performance testing issue: Don't know how to build task 'test:benchmark'

I'm following this railscast on performance testing, but I'm immediately running into an issue.
My app is rails 3.2.11, so according to the railscast it should include performance testing, but I don't have a folder called 'test' at all. When I run 'rails generate performance_test homepage' nothing happens or is generated. So I created one manually (to exactly match the railscast source code), but when I run rake test:benchmark I get the error
Don't know how to build task 'test:benchmark'
If I add the 'rails-perftest' gem to my gemfile and run bundle, then again try to generate a performance_test nothing happens, and when I then run rake test:benchmark, it throws a different error of
uninitialized constant Rails::SubTestTask
I've been sure to include the following dependencies in my gem file:
gem 'ruby-prof', group: :test
gem 'test-unit', group: :test
Could anyone help advise me what I'm doing wrong? Thanks!
I am not 100% certain on this, but I am guessing that you might not have your application.rb file configured accordingly. Also check your Gemfile.lock file and run the command bundle install because it could also be something funky going on with your Gems and dependencies.

How to set sinatra-authentication to use erb instead of haml?

I'm trying to set up the sinatra-authentication gem in a simple sinatra app, and running into an issue where sinatra can't find the correct views. I understand that sinatra-authentication uses haml by default, but I'm using erb in this app.
This in mind, I found in the sinatra-authenticaiton docs that there is a setting which allows you to change the template engine, by adding the following to your app file:
configure do
set :template_engine, :erb # for example
end
I've added this to my app.rb file, and sinatra is still looking for the signup.haml when I try to hit the /signup route in my app.
A couple of notes:
I've included the gem in my Gemfile, and successfuly run a bundle install on my app.
source 'https://rubygems.org'
gem 'sinatra'
gem 'data_mapper'
gem 'pg'
gem 'dm-postgres-adapter'
gem 'sinatra-authentication'
I saw something in the documentation that suggested that I may need to specify the location of my view files, so I added the following to my configuration block.
set :sinatra_authentication_view_path, Pathname(__FILE__).dirname.expand_path + "views/"
**I think I've required the gem accurately in my app file by adding
require "sinatra-authentication"
use Rack::Session::Cookie, :secret => 'mys3cr3tk3y'
This gist is a current representation of my app.rb file in the root of my sinatra app. https://gist.github.com/rriggin/5378641#file-gistfile1-txt
Here is a screenshot of the error sinatra throws: http://cl.ly/image/0y041t0K3u3O
When I run the app locally, a 'dm-users' table is created in my local db as expected.
Is there another configuration setting that I'm missing in order to get sinatra-authentication to properly look for the erb templates rather than haml files. Any help would be greatly appreciated.
Thanks
The specs don't test that the template_engine setting works, and looking at the way the setting is called, I believe it's not correct, i.e.
send settings.template_engine, get_view_as_string("index.#{settings.template_engine}"), :layout => use_layout?
might better work as:
send app.settings.template_engine, get_view_as_string("index.#{app.settings.template_engine}"), :layout => use_layout?
that's what I reckon. If you fork the project, change the line and add it to your Gemfile and it works then consider writing a quick spec for it and you'll have improved the mainline of that project as well as fixed your problem.

Global access to Rake DSL methods is deprecated

I am working through the Ruby on Rails 3 tutorial book and typed the following on the command line:
rake db:migrate
which produced the following warning.
WARNING: Global access to Rake DSL methods is deprecated. Please Include
... Rake::DSL into classes and modules which use the Rake DSL methods.
WARNING: DSL method DemoApp::Application#task called at /Users/imac/.rvm/gems/ruby-1.9.2-p180#rails3tutorial/gems/railties-3.0.7/lib/rails/application.rb:215:in `initialize_tasks'
I am not sure what to do about it or how to work with it. I don't know any other command for Rake.
How can I fix this problem?
Adding include Rake::DSL to the Rakefile before the applications load_tasks were called also worked for me.
So in the above user's case before the DemoApp::Application.load_tasks in the Rakefile.
I found this in Stack Overflow question Ruby on Rails and Rake problems: uninitialized constant Rake::DSL. It refers to a #DHH tweet.
Put the following in your Gemfile
gem "rake", "0.8.7"
You may see something like
rake aborted!
You have already activated Rake 0.9.1 ...
I still had a copy of Rake 0.9.1 in my directory so I deleted it.
You can "delete" Rake 0.9.1 by running the following command:
gem uninstall rake -v=0.9.1
If you have multiple versions of the gem installed, you'll be prompted to pick a version.
After 0.9.1 was cleaned out, I ran
bundle update rake
and was finally able to create my database files. I was using rake db:create, but it should work for rake db:migrate as well.
I hope it helps.
I was having the same problem on Windows with the installer. Ruby 1.9.2 and Rails 3.0.9.
Here is what I did:
bundle update rake
bundle show rake
After doing that I was running rake 0.9.2.
Then I updated the Rakefile in application root folder as follows:
require File.expand_path('../config/application', __FILE__)
require 'rake'
# If you named your application something other than SampleApp, change that below
module ::SampleApp
class Application
include Rake::DSL
end
end
module ::RakeFileUtils
extend Rake::FileUtilsExt
end
SampleApp::Application.load_tasks
As noted in the comment, make sure the name of your app is correct in the two appropriate lines above.
If you are seeing this on later versions of Rails (like 3.+) you may also want to verify that your environment is clean by using RVM http://beginrescueend.com/ and creating a specific ruby & gemset for your projects.
Use an .rvmrc file on a per-project basis, this will guarantee you aren't getting older system gems into your projects. Which has bitten me before.
This prevents having to monkey around with generated Rakefiles & such.
bundle exec rake db:migrate will solve your ruby version issues

Heroku app crashes, logs say "No such file to load -- nokogiri (LoadError)"

I had a working app, added Nokogiri, to parse some xml, runs fine locally.
My Gemfile includes: gem 'nokogiri'
I ran bundle install and verified my Gemfile.lock includes DEPENDENCIES ... nokogiri
In my controller class I added (didnt thinkI had to but got an error locally if I didnt):
class MydealController < ApplicationController
require 'rubygems'
require 'open-uri'
require 'nokogiri'
when I use my browser to get the url in MydealController that uses nokogiri doc = Nokogiri::XML(getresult) Heroku crashes.
heroku logs shows this error No such file to load -- nokogiri (LoadError)
Looking at what happens when I git push heroku I do not see nokogiri on the list of many many gems that get installed. Heroku says the push was fine, but nokogiri is not listed and I get the aforementioned error...
It seems that when using Windows Gemfile.lock will contain version of nokogiri gem specific for windows, solution is to remove Gemfile.lock and push to heroku.
More info on this subject here
Your mission should you choose to accept it.
Ensure:
nokogiri is in Gemfile.lock
Gemfile.lock is committed to git
you push the commit that has nokogiri in Gemfile.lock to Heroku
Good luck! This message will self destruct in 10 seconds...
Just had the same problem -- you have to run bundle install to get it added to the Gemfile.lock which heroku looks at to find uninstalled dependencies.
This might help to understand the reason:
http://devcenter.heroku.com/articles/ps
Indeed removing Gemfile.lock might help. All other compiled gem will cause isseu. Best way is to ask Heroku's support.
Only found this article:
http://ganeshprasadsr.blogspot.com/2010/10/installing-nokogiri-for-rails-3-app-on.html
Try to remove require 'nokogiri' from controller.
It works for me.
