Newbie to rails here, so bear with me.
New app on Rails 4 with ruby 2.0, I installed Devise and followed the instructions(default root, etc). Devise readme on github says it should be compatible with rails4 but
db:migrate failed unless I commented out attr_accessible line in User.rb
After commenting that out, I get "ActiveModel::ForbiddenAttributesError in Devise::RegistrationsController#create" error in trying to create a user.
I see some stack overflow questions like this, but a lot of the answers jump straight into some complex talk. I get I need to specify permitted attributes for mass assignment, but how? And where? And which attributes need to be permitted, all of them? Only those that I expect to be changed/created at the same time?
Judging by the error would I create a registrations_controller.rb that inherits from Devise::registrationsController ? What do I specify in that?
Any step by step, newbie friendly answers are much appreciated. I've exhausted myself trying different code from answers here and various sites from google searches.
Welcome to stackoverflow!
The problem is that the functinality of attr_accessible changed in rails 4.0
2 possibilities to get it running
1 Update Devise that it can handle Rails 4.0
Add this line to your application's Gemfile:
gem 'devise', '3.0.0.rc'
And then execute:
$ bundle
2 Add the old functionality of attr_accessible again to rails 4.0
Try to use attr_accessible and dont comment this out.
Add this line to your application's Gemfile:
gem 'protected_attributes'
And then execute:
$ bundle
Adding below gems and doing a bundle install worked for me
source 'https://rubygems.org'
gem 'rails', '4.0.2'
gem 'bootstrap-sass', '2.3.2.0'
gem 'devise', '3.0.0.rc'
gem 'protected_attributes'
gem 'sqlite3'

I have upgraded my application from Rails 2.3.5 to Rails 3.1.3. I had acts_as_commentable_with_threading and awesome_nested_set as plugins. Now I have added in GemFile for Rails 3.1.3 as below
gem 'awesome_nested_set'
gem 'acts_as_commentable_with_threading'
I have code in the model as below
class Post < ActiveRecord::Base
acts_as_commentable
end
The migration for acts_as_commentable_with_threading is already applied in the database.
I have statement in the view as
<%= pluralize(post.root_comments.size, "comment") %> on this post
When I try to load that view I get error at that line as
uninitialized constant Post::Comment
What can be the problem. Please help me.
Thanks in advance!
You might have forgot to run the generator and the migration afterwards:
rails generate acts_as_commentable_with_threading_migration
or
rails generate acts_as_commentable_upgrade_migration
and after:
bin/rake db:migrate
It's first steps of github repo instructions
I am trying to use geokit but I get the following message:
undefined method `acts_as_mappable'
I have tried the following solutions but nothing has worked so far:
Rails 3.1.0, geokit, with error acts_as_mappable
I am using rails 3.0.1 and ruby 1.9.2
I have followed the instructions here https://github.com/jlecour/geokit-rails3 but its not working
This is my model:
class Event < ActiveRecord::Base
acts_as_mappable :default_units => :kms,
:default_formula => :flat
end
and I have this in my gemfile
gem 'geokit-rails3'
I also have the folder vendor, inside I have a geokit-rails3 folder with the files, one of them named acts_as_mappable. I have tried adding require 'geokit-rails3' in the top of my model but it says no file to load.
I tried both, installing it as a plugin:
rails plugin install git://github.com/jlecour/geokit-rails3.git
and also by doing gem install (and it is shown when I list all the gems installed)
Any help is greatly appreciated.
The problem was solved by reinstalling rails with:
sudo apt-get install rails rails-doc rails-ruby1.8
I am trying to use the gem gchartrb to create some graphs/charts in my RoR application.
I have looked into several tutorial and all say the same thing, that I have to add
require 'google_chart'
But I am getting the message:
no such file to load -- google_chart
I have the require inside my controller, I have confirmed that the gem is installed.
I am using Rails 3.
Also, I have tried adding config.gem 'gchartrb', :lib => 'google_chart' in my environment.rb as suggested here but nothing changed
Thanks for your help
EDIT:
I have also tried with the gem googlecharts, what I have in my Gemfile is:
gem "googlecharts", :require => "gchart"
but I get no such file to load -- gchart when I try to load the view.
I am not sure, it is required now or not. But it worked for me in Rails 3 as well. I am using Rails 3.0.10. I added below 2 lines and it worked for me.
1) gem 'gchartrb' in Gemfile
2) require 'google_chart' in config/boot.rb
Hope it helps!
config.gem is for rails 2.3.X.
For rails 3, you will need to add the gem to your Gemfile and run gem bundle
You may also need to check that the google_charts gem actually supports Rails 3...
Given that the latest code update seems to have been in 2008 - that might not actually be likely. :(
You can try it anyway and see...
I have a Rails 3 app that I am turning into a Rails engine / gem.
This engine has some gem dependencies that I have put inside it's .gemspec file.
I have created a new 'parent' Rails 3 app, and I would like to add my engine gem to the Gemfile and have the gem's dependencies automatically 'loaded', but this does not work for me! bundle install installs the gem dependencies fine, but when I start the server, the app crashes because they are not loaded.
For example, my engine's gemspec contains these lines:
s.add_runtime_dependency(%q<rails>, ["= 3.0.7"])
s.add_runtime_dependency(%q<acts_as_commentable>, [">= 3.0.1"])
s.add_runtime_dependency(%q<haml>, [">= 3.1.1"])
.. and the parent Rails 3 application has these lines in its Gemfile:
source 'http://rubygems.org'
gem 'my_engine', :path => "~/src/gems/my_engine"
But I get the following error:
undefined local variable or method `acts_as_commentable'
from /home/user/src/gems/my_engine/app/models/account.rb:66:in `<class:Account>'
But if I add gem 'acts_as_commentable', '>= 3.0.1' to the Gemfile of the parent Rails 3 app, then the gem is loaded and the error disappears.
I am using Rails 3.0.8.
Does anyone have any suggestions? Do I need to change something about the way my engine is loading?
During main Rails app boot, Bundler will only require dependencies directly listed in the Gemfile but not any sub-dependencies. It's your library's/Engine's responsibility to require its dependencies when it itself gets required. You can do so using initializers in your Railtie.
class MyRailtie < Rails::Railtie
initializer "require stuff" do
require "stuff"
end
end
In our Rails Engine we used a small trick to require dependencies automatically. Unfortunately you can't specify whether or not they should load in the .gemspec, which would allow for greater control.
Gem.loaded_specs["our_rails_engine"].dependencies.each do |d|
begin
require d.name
rescue LoadError => le
# Put exceptions here.
raise le if d.name !~ /factory_girl_rails/
end
end
I'm looking at Spree (the superhero of Rails Engines!), and they do this in spree_core-0.60.1/lib/spree_core.rb:
require "rails/all"
require 'state_machine'
require 'paperclip'
require 'stringex'
require 'will_paginate'
require 'nested_set'
require 'acts_as_list'
require 'resource_controller'
require 'active_merchant'
require "meta_search"
require "find_by_param"
So the answer is that within your gem, you have to require all of it's gem dependencies one by one. Well, that's how I will do it for now. But please comment if this ever changes in the future.
Seems it don't work, i create a host project and a sub-project with rails 3 engine.
Added the gem to engine's gemspec
s.add_dependency 'simple_form'
then added the require to engine_name.rb like below
require 'simple_form'
But if delete the line [gem 'simple_form'] in host project's Gemfile, it will show undefined immediatly
Hi
I know this question have been asked before but the answers there isn't working for me.
I still get the, when redirecting back to my site.
/auth/failure?message=invalid_response
I have ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.6.0] installed, using rails 3.0.7 and the required gems installed. I read on another thread that you should have pure_json added to the gemfile to make it work. But that didn't help me either.
I'm clueless... Thanks in advance
authenticationscontroller
def index
#authentications = current_user.authentications if current_user
end
def create
#render :text => request.env["omniauth.auth"].to_yaml
auth = request.env["omniauth.auth"]
current_user.authentications.find_or_create_by_provider_and_uid(auth['provider'], auth['uid'])
flash[:notice] = "Authentication successful."
redirect_to authentications_url
end
I was able to get this to work by specifying the following in my Gemfile
gem 'omniauth', '0.2.0'
Version 0.2.6 wouldn't work for me. I also updated by .rvmrc to rvm use 1.9.2#rails3. Oh, also make sure you're logged in - do note that in your code above you are assuming that current_user exists. See Ryan's Railscast part two for allowing user creation via Omniauth.
I've got a demo working here, but do note I'm doing authentication from scratch rather than using Devise.
