When using a subdomain and trying to view anything related to current_user. user is sent to a new session page, the page shows the session is created and gives the option to logout. I can use no subdomain and it works fine.
Set it in your environment.rb (or environments/*.rb if you'll use different domains for each environment):
ActionController::CgiRequest::DEFAULT_SESSION_OPTIONS.update( :session_domain => '.domain.com')
FYI... as of Rails 2.3, this setting has changed. The rails 2.3+ version looks like:
ActionController::Base.session_options[:domain] = '.domain.com'
Just in case anyone else lands here from Google and gets confused like I did.
#jkrall - to add to that, the whole options hash moved to :key, :secret, and :domain vs :session_key, :session_domain, etc.

I'm building a API and want the show page for a user to be found by 'uid' instead of the record ID
I have this in my controller
def show
respond_with User.find_by_uid(params[:uid])
end
When I go to localhost/api/v1/users/8888888 Its returns "Null"
Finding by ID seems to work fine, am I doing something wrong here?
I tried put this in the rails console and it worked
User.find_by_uid("8888888")
I'm new to rails
Thanks
have you tried visiting:
localhost/api/v1/users?uid= 8888888 instead of the url you are using currently, except you are handling that correctly rails would have no knowledge of the uid param alternatively you could add this to your config/routes.rb file
get 'users/:uid', to: 'users#show'
With the hope that your controller is called UsersController then you can call localhost/api/v1/users/8888888 in your browser and it should behave as expected
Rather than just giving you the answer, I'll provide a tip on debugging Ruby applications (including Rails).
Get the pry gem and the pry-debugger gem and include them in your Rails application (there's plenty of posts around Google on how to include pry and pry-debugger in Rails).
put 'binding.pry' (without the quotes) at the beginning of your show method. In the console where your server runs, when show gets executed, execution will halt/pause at binding.pry. Type the following in the pry console to see what is available in the rails params hash.
pry> params
(this will print out the contents of params)
I would start my troubleshooting here, and post the contents of params and any relevant server logging here if you still can't figure it out.

I don't have enough rep to comment, yet. Only really been on this site and using it a day or two.
I just deployed one of my apps to heroku. This app uses :
A default "myapp.herokuapp.com" address,
And I got a domain configured so that the app can be reached through "www.myapp.com".
And I noticed today the following issue : my application links are based on "http://myapp.herokuapp.com" domain (hence I get "http://myapp.herokuapp.com/page" URLs) even when I access the app using my domain name (I would then expect to get "www.myapp.com/page" URLs).
I tried to edit my production.rb and set the default_url_options :
# Base domain for url generation
config.action_controller.default_url_options = { :host => "www.myapp.com" }
But it doesn't change a thing. Also tried to change this in application.rb, just in case, but nothing happens either.
Any clue ?
Thanks a lot for your help guys !
Edit : This used to work as expected before today when I did the database migration to the new Heroku postgres thing. Don't know if this can have any impact.
If you're using _path methods for your urls, this is generating a relative path which is always based on the url you visit. If you're using controller/fragment caching, you should probably use _url instead in your views. You might also want to consider setting config.action_controller.perform_caching to false in your production.rb if all your pages have some controller logic.
See this page for more info on how caching works in Rails.
I had a similar problem. It was caused by the following line of code which was pointing to heroku.com and getting redirected to herokuapp.com
config.action_mailer.default_url_options = { :host => 'my-staging-domain.heroku.com' }
I mention it because it's the action_mailer.default_url_options yet clearly it affects the default url options outside of the scope of the mailer if you haven't explicitly set up the action_controller.default_url_options
how can I get the subdomain value in rails, is there a built-in way to do this?
e.g.
test123.example.com
I want the test123 part of the url.
Rails 3.0 has this capability built-in, you can access the subdomain from request.subdomain.
You can also route based on the subdomain:
class SupportSubdomain
def self.matches?(request)
request.subdomain == "support"
end
end
Basecamp::Application.routes do
constraints(SupportSubdomain) do
match "/foo/bar", :to => "foo#bar"
end
end
If you're using 2.3, you'll need to use a plugin such as subdomain-fu.
Use the following method inside your controller
request.subdomains
This Returns an array of subdomains
account_location is also a good plugin. After using it, you can find the account based on different subdomains. And you can find out subdomain from url just by writing request.subdomains(0).first in your code.
In case you are working with a string, and assuming it can be a true URI, you can do this to extract the subdomain.
require 'uri'
uri = URI.parse('http://test123.example.com')
uri.host.split('.').first
=> "test123"
https://stackoverflow.com/a/13243810/3407381
Simple in your controller just do the following
unless request.subdomains.any?
#No domains available redirect
redirect_to subdomain: 'www'
end
You can use the SubdomainFu plugin. This plugin gives you a method current_subdomain which returns the current_subdomain of your app.
You can also have a look at this Railscast
UPDATE
You can also use request.subdomains this will give you an array of subdomains.
For anyone looking to get the subdomains on localhost using WEBrick:
Put config.action_dispatch.tld_length = 0 into config/environments/development.rb and everything should work.
Link to SO post here:
Can I make Rails / WEBrick recognize entries in /etc/hosts as subdomains (instead of domains)?
Link to Github post:
https://github.com/rails/rails/issues/12438
current domain with subdomains:
"#{request.subdomain}.#{request.domain}"
# or
"#{request.subdomains.join(".")}.#{request.domain}"
A bit late to the party but here's what I used in older versions of rails.
subdomain = request.subdomains.join('.')
It should be backwards compatible in newer versions
I have an application with Rails 2.3.5. And Im trying to use AS latest version, I have used it previously but cant make it work here.
I have my ingredient_categories Controller, where i put
class Administration::IngredientCategoriesController < ApplicationController
layout "default"
active_scaffold :ingredient_categories
end
I have this set up on routes to be :active_scaffold=>true
I have a model also called ingredient_category, and in the views folder (inside administration/ingredient_categories, and /ingredient_categories) i have nothing as it is usual.
And Im getting over and over again:
Template is missing
Missing template ingredient_categories/list.html in view path themes/aqueouslight:app/views
I had an error before asking me for a list.erb, which I created and put
'ingredient_categories', :label => 'Categorias' %>
And now this error of the list.thml...
Cant make it work! dont know whhy really... whould be SO simple and its burning my head now..
Thanks!
Make sure you have the render_component plugin installed, as it was deprecated from rails 2.3.x and is used by active scaffold
This may not be the cause of your particular problem but you will have trouble with it if you combine AS+Rails2.3.x
I hope it helps
I'm messing around with rails 2.3 templates and want to be able to use the app name as a variable inside my template, so when I use...
rails appname -m path/to/template.rb
...I want to be able to access appname inside template.rb. Anyone know how to do this?
Thanks
I was looking for an answer to this question. unfortunately the answer above (#root) doesn't seem to work in Rails 3.
Here's the variables you can access in Rails 3 app templates (even easier):
#app_name
#app_path
Thanks for the answers. Mike Woodhouse, you were so close. Turns out, all you need to do to access the appname from inside your rails template is...
#root.split('/').last
The #root variable is the first thing created when initializing templates and is available inside your rails templates. RAILS_ROOT does not work.
In Rails 3, use the app_name attribute.
See the documentation for the Rails::Generators::AppGenerator.
I ran into a similar problem, none of the variables listed above were available to me in Rails 4. I found that #name was available while running
rails plugin new engines/dummy -m my_template.rb
There are other useful variables available from within the template. You can see for yourself and play around by utilizing pry. Inside my template I added
require 'pry'; binding.pry
and then ran ls to show a list of available instance variables
ls -i
instance variables:
#_initializer #app_path #behavior #destination_stack #extra_entries #name #output_buffer #shell
#_invocations #args #builder #dummy_path #gem_filter #options #rails_template #source_paths
#after_bundle_callbacks #author #camelized #email #in_group #original_name #shebang
There's probably a more straightforward way, but this seems to work:
RAILS_ROOT.split('/').last
EDIT: Bleah - this got voted down once, and the voter was right. If I'd read the question more carefully, I'd have noticed the 2.3 and template.rb elements. Apologies.
I suspect that RAILS_ROOT won't have been created at the point that you need the app name. Looking at ruby\lib\ruby\gems\1.8\gems\rails-2.2.2\bin\rails, however, almost the first thing that happens is this:
app_path = ARGV.first
It's used at the end of the script to allow a chdir and freeze to be done if needed - I didn't know I could insta-freeze at creation, so I learned something new at least. ARGV then gets used here:
Rails::Generator::Scripts::Generate.new.run(ARGV, :generator => 'app')
which quickly gets us to the place where ARGV is really handled:
rails-2.3.1\lib\rails_generator\scripts.rb
where I see
Rails::Generator::Base.instance(options[:generator], args, options).command(options[:command]).invoke!
Somewhere below here is probably where the templating gets handled. I'm afraid I'm at a very early stage with 2.3 and templating is an area that I haven't looked at yet.
Does that help any better than my first effort?
RAILS_ROOT will give you the absolute path to your root directory. Your app name will be the portion of the string after the final '/' which you can grab in any number of ways.
EDIT: Not quite enough to get the job done. Mike and Dan iron it out below.
I believe the preferred way now is to call Rails.root and no longer RAILS_ROOT. Apparently someone on planet rails has an aversion to uppercase or some similar important reason. As of 2.3.5 they both appear to work.
I was getting error
`template': undefined local variable or method `app_name'
ruby 1.9.2p290, rails 3.2.11, thor 0.18.0, Windows
but with rails 2.3 generator:
class DynanavGenerator < Rails::Generators::Base
(can't be sure whether this error happened under rails 3.0.9 or earlier)
changed class definition to be:
class DynanavGenerator < Rails::Generators::NamedBase
which then gave:
No value provided for required arguments 'name'
I then added a 'name' ("something" below):
rails generate dynanav something --force
which gave the original error, so I then added:
def app_name
#name.titleize
end
to the class and all was well.
As of Rails 4 (maybe earlier versions?), use Rails.application.class to get the application name. For example, if your app is named Fizzbuzz, here are a few ways you might access it:
rails(development)> Rails.application.class
=> Fizzbuzz::Application
rails(development)> Rails.application.class.name
=> "Fizzbuzz::Application"
rails(development)> Rails.application.class.parent
=> Fizzbuzz
rails(development)> Rails.application.class.parent.to_s
=> "Fizzbuzz"
