I'm trying to use this command in Terminal: rails generate layout simple --force and when I do I get this error: Could not find generator layout. So I attempted to try to be more specific in my gemfile, and added the specific, newest version number to the file (gem 'rails_layout', ~> '1.0.5'), and still get the same error. I did a little searching and found this similar question: zurb_foundation layout generation in rails and the answer seems to say that Foundation now includes the layout generator in it's own gem? Or am I reading that wrong? Anyway, I did a gem uninstall rails_layout and then tried the original command again. Still, no go. Same, original error of not being able to find the layout generator. I'm on Rails 4.0.2 and Ruby 2.0.0 Does anyone have any suggestions? Thank you!
You're reading the book Learn Ruby on Rails. But you're reading an out-of-date version of the book. The latest version of the book is v1.19. You'll see the correct syntax for use of the rails_layout gem is:
$ rails generate layout:install simple --force
If you check the README for the rails_layout gem you'll see the correct commands:
https://github.com/RailsApps/rails_layout
The rails_layout gem gives you an easy way to set up application layout, flash messages, and navigation partials. If you don't use the generator command, you can copy the example code from the book to get what you need (the generator command gives you a shortcut). Later in the book, you'll learn how to install Foundation and set up the application layout, flash messages, and navigation partials for Foundation. You could follow the instructions on the Foundation website but again, the rails_layout gem gives you a shortcut.
In summary: Make sure you have the newest version of the book.

I am trying to understand some of the higher level functioning of Rails, using the Rails console. I run controller.class.superclass.superclass which gives ActionController::Base, controller.class.superclass.superclass.superclass which gives ActionController::Metal and controller.class.superclass.superclass.superclass.superclass gives AbstractController::Base.
I have found these in the API documentation.
http://api.rubyonrails.org/classes/AbstractController/Base.html
http://api.rubyonrails.org/classes/ActionController/Metal.html
[can only post two links]
I can add to these simply by declaring the classes again in the console, but is there a way to find the original Ruby code for these and to inspect and edit it in its original file(s)? Just in case I need to know the full contents of these for future.
You can also do:
bundle show <gem>
and that will show you where the gem is on your system. Editing in those files is not advised unless you know how to re-install gems.
You can see the Rails source code on Github:
https://github.com/rails/rails/tree/master/actionpack/lib/action_controller
I'm following Vic Ramon's tutorial. I tried to use the latest version of Rails and Ember-source and I get the following error when visiting home page:
After clicking on link next to error I get this:
How can I fix that?
I ran the following commands:
rails g ember:bootstrap -n App --javascript-engine coffee
rails g ember:install
I removed turbolinks. I also created home controller and an empty view for home#index. Root is set to home#index. Also created following view file:
// app/assets/javascripts/templates/application.js.emblem
h1 Hello World

Ember gems im using:
Using emblem-source 0.3.18
Using ember-data-source 1.0.0.beta.14.1
Using ember-rails 0.16.1
Using emblem-rails 0.2.2
This could be due to some version incompatibilities between your versions of ember-related gems, as there were quite substantial changes in recent versions of ember (e.g. introduction of HTMLBars, etc.)
Your best bet is to clone the original repo and then try to upgrade individual gems and check if it still works after each upgrade. This way you will be able to identify the troubling gem.
I have verified that the original repo code indeed works with the versions of gems in its current Gemfile.lock.
If you are starting a new Rails + Ember app, ember-cli-rails is probably the way to go, giving you the best of both worlds.
Emblem was the culprit. Replacing .emblem with .handlebars fixed the problem. I tried the tip from emblem-rails git page and icluded
gem "emblem-source", github: "machty/emblem.js"
but that didn't change anything.
I also followed this tutorial (alongside a few others) and I encountered several issues alongside the way ranging from handling templates to setting up the JSON API. I don't see your entire source code so I cannot pinpoint the exact problem. However, it seems that we have similar projects, so you can compare your code to my blog project source code and see what is causing these issues. Comparing to Ramon's tutorial, my blog has implemented everything until chapter 15.
https://github.com/Deovandski/Fakktion/tree/Ember-Rails
If you are a beginner like myself, then I recommend avoiding CoffeeScript and Emblem and sticking to Javascript as much as possible for the first months because you will find more resources and examples. Also, let me know if you need assistance in setting up the project as I used .gitignore to hide things like secrets.yml
I'm using the ruby 2.1.2p95 version, and I'm running into some problems following directions to this tutorial (http://tutorials.jumpstartlab.com/projects/blogger.html) on creating a blog.
I followed exactly what the tutorial said, up until the step "Setting up the router." Once I open config/router.rb, the first line in my document is "Rails.application.routes.draw do," not "Blogger::Application.routes.draw do."
The reason I'm asking is in the tutorial on Jump Start Lab, after I continued to the "Creating Template Step," I received a different error message from "Template missing...". I got "Unknown actions...", and eventually, I couldn't view the index page.
I also looked at another tutorial on Youtube (https://www.youtube.com/watch?v=-GQmC-8k09c), and I got the same problem, where the config/router.rb's first line remains the same.
Do you know why this is happening?
Am I supposed to manually change the first line from "Rails.application..." to "[Name of app]::Application.routes.draw do"?
I try with Rails 4.0.4, and it's Blogger::Application.routes.draw do but with rails 4.1.4 it's Rails.application.routes.draw do. I didn't see any news about new router api, so it should be same.
But if you wanna follow tutorial then you can make:
gem uninstall rails
and remove rails 4.1.* then install rails 4.0 with command
gem install rails -v 4.0.8
I am facing an issue in my application with tiny mce.
All the gem version & ruby version is OK on my system, but it is giving me error
= undefined method `uses_tiny_mce'
Here i installed the tiny_mce gem. COnfigured it correctely, but still there is an issue.
Please help.
Did you include
config.gem 'tiny_mce'
in config/environment.rb?
I have used this gem in the past too, but have stopped using it. I figured it complicated the setup and deployment of my Rails apps. Since then I have just used the TinyMCE editor by itself. Since it is 100% javascript, it does not touch any Ruby code which keeps things better organized.
I was not using this as a plugin.
I have followed the steps given in the,
http://enginey.googlecode.com/svn/trunk/vendor/plugins/tiny_mce/README.rdoc
Steps :
script/plugin install git://github.com/kete/tiny_mce.git
rake tiny_mce:install
my issue got resolved.
I have assigned to use jasperserver reports in a rails application.
There is a plugin for jasperserver to use in Ruby application.
https://github.com/gunark/jasperserver-client
I want to know whether this plugin can use in my rails 3 version of application.
I've checked in railsplugin.org .But it shows "no result found".
I'l be please if u people gave me any help link.
According to the wiki, the author recommends you install it as a gem & not as a plugin. They go on to give an example of how to use the gem in a rails project on this wiki page.
I haven't used this, but your compatibility issues probably won't be with rails. Maybe the ruby version or soap4r version - but there don't seem to be any rails dependencies here.
You maybe use this simple ruby script for this => http://www.redrails.com.br/2013/03/07/ruby-client-para-rest-api-do-jasper-report-server/
