When I 'rails server' the localhost:3000 works in my browser (chrome). Here's the term:
tom#toms-ubuntu:~/rails_projects/routesapp$ rails s
=> Booting WEBrick
=> Rails 3.2.16 application starting in development on http://localhost:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

[2016-01-12 10:56:27] INFO WEBrick::HTTPServer#start: pid=4751 port=3000
But for localhost:3000/page/home the browser displays:
NoMethodError in Page#home

I generated the html files shown in the routes.rb file below; the html files are located in app/views/page
Routesapp::Application.routes.draw do
get 'page/home'
get 'page/about'
get 'page/contact'
Any ideas, comments, suggestions will be much appreciated. This is new to me. Thanks
Since you're a beginner, let me explain.
Your pages are showing; you've got an error:
undefined method `[]' for nil:NilClass
This is a standard Ruby error - it means undeclared variable.
Since Ruby is Object Orientated, it assigns "nil" values to the NilClass -- meaning that you end up with strange errors.
--
Normally, with debugging, you'll be able to reference the line number, and see what the issue is.
Because you've not included your view, I can only suggest that you try removing the following lines as a test:
5: <%= stylesheet_link_tag "application", :media => "all" %>
6: <%= javascript_include_tag "application" %>
If these work to resolve the issue, you'll have to either populate app/assets/javascripts/application.js or app/assets/stylesheets/application.css, or use something like nodeJS which works to resolve errors like this.
You'll also be better using the following for your routes:
#config/routes.rb
resources :pages, path: "page", only: [] do
%w(home about contact).each do |page|
get page
end
end
Buddy take "application" on line #5 and #6 and change that "application" word to "defaults"

Firstly I'm still busy learning RoR so my understanding is limited. I created a new simple project and generated my first scaffold named 'Person'. When I start up my WEBrick server I go to localhost:3000/people I get the following runtime error:
ExecJS::RuntimeError in People#index
Showing C:/Users/Dean/Desktop/guestbook/app/views/layouts/application.html.erb where line #6 raised:
(in C:/Users/Dean/Desktop/guestbook/app/assets/javascripts/people.js.coffee)
Extracted source (around line #6):

6: <%= javascript_include_tag "application" %>
7: <%= csrf_meta_tags %>
8: </head>
9: <body>
If any more clarification is needed please let me know and I'll gladly update my question.
I'm no expert but it looks like it's something to do with.. the coffeescript gem? I'm really just spitballin' here... Thanks in advance!
people.js.coffee:
# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://jashkenas.github.com/coffee-script/
ExecJS::RuntimeErrors are typically caused by syntax errors in your coffeescript. Check your people.js.coffee file around line 6 and make sure it is syntactically correct. If you are relatively unfamiliar with coffeescript, http://js2coffee.org/ converts between JS and coffee and might be helpful. .js.coffee files will only accept coffeescript.
I'm at 5.1.2 of the railstutorial, I have just installed Bootstrap-sass (I've double checked, the gem is there). http://ruby.railstutorial.org/chapters/filling-in-the-layout#top
I added this file:
app/assets/stylesheets/custom.css.scss
And when I give it this content:
#import "bootstrap";
My http://localhost:3000/static_pages/home does not work anymore. It gives the following error:

Any help would be much appreciated, thanks!
Your gems is in E: while your app is in C:\
When trying to #import, Assets module will search several places including gem path. But it can't recognize the disk within the path. That's why your #import fails.
Suggestion: Put your app and gems in same disk.
Side note: Don't use Windows for Rails development at all.
I just installed passenger and I believe I got it working, but now my rails application seems to be unable to load cached assets. When attempting to load a page I get this message:
ActionView::Template::Error (No such file or directory - /home/glawson/vidStream/tmp/cache/assets/sprockets%2Ff1663d34d4b6003379113df98f1433a520130421-27670-18ux0pw.lock):
2: <html>
3: <head>
4: <title>VidStream</title>
5: <%= stylesheet_link_tag "application", :media => "all" %>
6: <%= javascript_include_tag "application" %>
7: <%= csrf_meta_tags %>
8:
app/views/layouts/application.html.erb:5:in `_app_views_layouts_application_html_erb___4187138815701226714_20468720'
This happens when I try to run my webapp with passenger or in development with rails server. I'm a little fuzzy on what the error even means other than it can't find a file that it's looking for.
In production mode you need to precompile the asset directory using
RAILS_ENV=production rake assets:precompile
Then only it will work. Because by default for prod asset precompile is enabled.
I successfully deployed my rails app to my VPS, but when I try to look at my server from browser, I get a 500 error ("We're sorry, but something's wrong"). The app is working fine locally, so I think the problem lies in not my code but somewhere else.
Here's the log from /current/log/production.log
ActionView::Template::Error (jquery.js isn't precompiled):
4: <title>Songhomme</title>
5: <%= stylesheet_link_tag "application", :media => "all" %>
6: <%= javascript_include_tag "application" %>
7: <%= javascript_include_tag 'jquery' %>
8: <%= csrf_meta_tags %>
9: </head>
10: <body>
app/views/layouts/application.html.erb:7:in `_app_views_layouts_application_html_erb___2525571063257357898_28769560'
I also got the following error:
ActionView::Template::Error (/home/deployer/apps/songhomme/releases/20121204091428/app/views/posts/_posts.erb:27: syntax error, unexpected ',', expecting ')'
...ppend= ( link_to (t.name + " ", '/tags/' + t.id.to_s) );#out...
The code is working fine locally, so I'm not sure what's wrong with the second part of code. For the first part of code, does running rake assets:precompile before I push to my repo solve the problem?
I appreciate your help.
Try declaring your js includes in the manifest file application.js , not by javascript_include_tag. Since Rails version 3 this is the proper way . So , in your application.js :
//= require jquery
//= require jquery_ujs
I am facing a problem when i fetched the rails project from github.
When i cloned the repository and try to run the code from a remote system, i got the following errors.
["ok","(function() {\n\n\n\n}).call(this);\n"]

I am currently using rails 3.2.0 in windows environment.
I have created only a simple rails project with user scaffold in order to test it.
Its working fine while i worked with that in my local system before moving to github.
Thanks,
Mani
It's quite strange, I might recommend that you delete everything in the user.js.coffee and save it and try again. It looks that there's some wrong returns in there.
