I'm trying to upgrade to rails 4 beta 1, but I've a bit of a problem.
This is, in short, how my application controller looks like.
class ApplicationController < ApplicationController
caches_action :method
end
caches_action is moved out to it's own gem in Rails 4, so including the gem should fix the problem.
gem "actionpack-action_caching", github: "rails/actionpack-action_caching"
But when I run my requests specs or visit the application in a browser I get this error.
app/controllers/application_controller.rb:3:in `<class:ApplicationController>': undefined method `caches_action' for ApplicationController:Class (NoMethodError)
Why is that?
Rails 4.0.0.beta1
Ruby 2.0.0
Rspec 2.13.1
As the caching is not a part of core anymore, you need to explicitly require it in top of every file you use it in:
require 'actionpack/action_caching'
The problem is in Rails 4, they have extracted cache part into separate gems
if you are getting error for action caching then you need to add below gem
gem 'actionpack-action_caching'
for page caching have to add
gem 'actionpack-page_caching'
I also played around then I figure out that, have not added gem to do the same.
hope that will works. Thank you.
Iam using rails as an API rails new AppName --api
I got it working by adding
include ActionController::Caching
in class ApplicationController < ActionController::API

Cant figure out what I'm doing wrong.
Using hidemyass gem for proxy.
Using github example code.
class HomeController < ApplicationController
require 'hidemyass'
def index
HideMyAss.options[:max_concurrency] = 3
response = HideMyAss.get("www.google.com", timeout: 2)
end
end
Whey I try to use them in my rails controller, I get the Uninitialized constant error.
uninitialized constant HomeController::HideMyAss
Tried looking at the source to figure out with no luck. Maybe it's the problem with my code. Gemfile is good and tried looking at all the things causing the problem.
There is no need to write require 'hidemyass'
You just need to add gem 'hidemyass' to Gemfile and do bundle install. Check installation with gem list hidemyass command. I have successfully checked it and used github example. It works fine and smoothly.
I am attempting to use the songkickr gem in a rails app. I have installed the gem using the
gem install songkickr
The next step of the instruction is to:
require 'songkickr'
remote = Songkickr::Remote.new API_KEY
Where do I do this? In what file?
The github page for the gem is https://github.com/jrmehle/songkickr
and my github for this is on https://github.com/jeremybelcher/travel
Sorry for the beginner question, trying to lean al this. Any help is very much appreciated.
In your gemfile at your application root you need to add the line
gem 'songkickr'
Then run
bundle
There are several places where you can put ruby code in a Ruby on Rails app and you should just choose one of them, depending which makes the most sense for you application. For a start, how about you just try putting that code in one of your controllers?
In your Gemfile, add:
gem 'songkickr'
Then run the following command: bundle
At the top of the controller put:
require 'songkickr'
API_KEY = "" # edit this line
Then in some action you can do this to test it out:
remote = Songkickr::Remote.new API_KEY
Later you might decide to make the "remote" object persist between requests and then you would need to do something more complicated.
Add require 'songkickr' to your application controller
Example:
class ApplicationController < ActionController::Base
protect_from_forgery
require 'songkickr'
end
I am trying to prepend views to the rails view array e.g.
prepend_view_path("#{Rails.root}/app/views/custom/blah")
This works fine, however in my test suite I keep seeing
DEPRECATION WARNING: process_view_paths is deprecated and will be removed from Rails 3.2.
After a bit of research I see mention of ActionView::PathSet, but cannot find any help searching google or in the Rails API documentation. I need to know how to use this new way of prepending paths in rails 3.2
I would really like to get rid of this warning. Any thoughts?
If it is dynamic (set on a per-request basis):
class ApplicationController < ActionController::Base
before_filter :set_view_path
def set_view_path
prepend_view_path "#{Rails.root}/app/views/custom/blah"
end
end
I think it went to AbstractController::ViewPaths, but still available from controller - should be without deprecation.
If you prepend static fixed path:
# config/application.rb
config.paths.app.views.unshift("#{Rails.root}/app/views/custom/blah")
I'm quite a beginner with Ruby On Rails and I need to implement client part of JSON API in order to use some external service.
I found a gem called jsonrpc and it looks perfect for me.
I've added it to my Gemfile as:
gem 'jsonrpc'
gem 'json'
and ran bundle
My code looks like this:
class SearchController < ApplicationController
def index
d = JsonRpcClient.new 'http://remote.bronni.ru/Dictionaries.ashx'
#countries = d.getCountries
end
But when I try to access it as http://localhost:3000/search, Rails says:
NameError in SearchesController#index
uninitialized constant SearchController::JsonRpcClient
I only have little experience with Rails so I'm asking you guys to help me out.
I really need to get this to work ASAP.
Thank you all in advance! I really appreciate your help!
UPDATE
I've tryed to get ActiveResource to work but I can't get how it build URL's. The remote service is not a Ruby XML app. (http://remote.bronni.ru/Dictionaries.ashx) And I need to use getCountries method so the URL should be http://remote.bronni.ru/Dictionaries.ashx/getCountries
I've gotten my application to work (i.e. sign_in and sign_up) with Authlogic and I'm now trying to add support for OAuth through the Authlogic_OAuth gem. I've gotten all of the basics set up (I think) and I've added a "Login with Twitter" button to my landing page. The problem is that when I click the button I get this error:
uninitialized constant UserSession::OAuth
with the application trace:
app/models/user_session.rb:17:in `oauth_consumer'
app/controllers/user_sessions_controller.rb:23:in `create'
The function that is failing is in my user_session model:
# authlogic_oauth hacks
# Twitter example
def self.oauth_consumer
OAuth::Consumer.new("TOKEN", "SECRET",
{ :site => "http://twitter.com",
:authorize_url => "http://twitter.com/oauth/authenticate"})
end
I'm pretty new to rails and ruby so I don't quite understand where this namespace collision is coming from or how to solve it. Any help would be greatly appreciated.
OK, I figured it out. The problem is that OAuth::Consumer is not defined withing authlogic_oauth. It's actually defined in the oauth gem. so I updated my Gemfile to:
gem 'authlogic', '2.1.6'
# set up oauth capabilities. Note: :lib is replaced with :require in rails 3
gem 'authlogic-oauth', '1.0.8', :require => 'authlogic_oauth'
gem 'oauth', '0.4.4'
then run:
bundle install
and, don't forget to restart the rails server so that it reloads the gems from the Gemfile.
Try to change OAuth to ::OAuth. The colons mean that you want to access OAuth from outside your class. It was searching from your class.
