I'm trying to define a route in routes.rb and I can't do anything from this Ruby on Rails routing guide that will let this error pass.
No route matches {:controller=>"devise/home"}
Here's my routes.rb source.
SchoolCMS::Application.routes.draw do
root :to => "home#index"
devise_for :teachers, :admin
resources :home, :only => :index
resources :admin, :only => :index
resources :events do
resources :event
end
resources :posts do
resources :comments
end
end
Just to be safe I would remove devise_for :teachers, :admin and split it so that it is
devise_for :teachers
devise_for :admin
I'm not sure you can specify multiple devises the way you use it, see if this fixes your error.
Also try to use path helpers were possible so instead of doing <%= link_to 'Home', :controller => 'home' %> make it <%= link_to 'Home', homes_path %> but make sure you define your home as resource :home, :only => :show since it's a singular resource.

I'm trying call a demo method in my controller. So, in my _form.html.erb I have:
<%= link_to 'Demo', "/admin/clinics/"+#clinic.id.to_s+"/demo" %>
In my routes.rb:
match "/admin" => "admin#index", :as => :admin
namespace :admin do
resources :admin_users
resources :health_plan_tables
resources :health_aid_tables
resources :clients
resources :clinics
resources :specialties
resources :qualifications
resources :profissionals
resources :addresses
resources :documents
resources :banners
root :to => 'banners#index'
get 'logout' => 'devise/sessions#destroy'
get 'clinics/:id/demo', to: 'admin/clinics#demo', as: 'demo'
end
My clinics_controller.rb is inside the folder controllers/admin, and I just have:
def demo
print "hello"
end
So, when I click on link, error message appears Uninitialized constant Admin::Admin.
Any ideia how to fix it?
Since you are already defining your demo route inside a namespace there is no need to specify admin/clinics#demo, just clinics#demo will be necessary:
namespace :admin do
resources :admin_users
resources :health_plan_tables
resources :health_aid_tables
resources :clients
resources :clinics
resources :specialties
resources :qualifications
resources :profissionals
resources :addresses
resources :documents
resources :banners
root :to => 'banners#index'
get 'logout' => 'devise/sessions#destroy'
get 'clinics/:id/demo', to: 'clinics#demo', as: 'demo'
end
According to the error log you're looking for a controller namespaced under admin/admin/clinics (it says that in the controller part of the params).
Change the bottom route to not include admin (it's already namespaced and you're effectively namespacing it twice):
get 'clinics/:id/demo', to: 'clinics#demo', as: 'demo'
This will route to the correct controller, admin/clinics, instead of admin/admin/clinics
I'm trying to implement semi-static pages as per this railscast
At first I named my class 'About', but that threw the following error:
Invalid route name, already in use: 'page' (ArgumentError)
You may have defined two routes with the same name using the :as option, or you may be overriding a route already defined by a resource with the same naming.
After some googleing, it seemed like it was conflicted with active_admin for some reason, so I rename the table to 'Page' and I've carefully renamed all the appropriate files, classes and methods etc. from 'About' to 'Page'
This is my Page model:
class Page < ActiveRecord::Base
validates_uniqueness_of :url
def to_param
url
end
end
And these are my routes:
get 'signup', to: 'users#new', as: 'signup'
get 'login', to: 'sessions#new', as: 'login'
get 'logout', to: 'sessions#destroy', as: 'logout'
devise_for :admin_users, ActiveAdmin::Devise.config
ActiveAdmin.routes(self)
resources :users
resources :sessions
resources :password_resets
resources :posts do
resources :comments
resources :votes, only: [:new, :create]
resources :flags, only: [:new, :create]
end
resources :comments do
resources :comments
resources :votes, only: [:new, :create]
resources :flags, only: [:new, :create]
end
resources :newsletters
resources :pages, except: :show
resources :subscribers, only: [:index, :new, :create]
# resources :prelaunch
# get 'about', to: 'prelaunch#about'
root to: 'posts#index'
get ':id', to: 'pages#show', as: :page
I'm still getting the same error as described above.
The only way I can get it to half-work is by dropping the 'as: :page' bit, which stops the conflict, and hardcoding the url I want to point to into the code e.g.
<%= link_to page.name, "localhost:3000/#{page.url}" %>
which is far from ideal.
I can't find any help in Routing from the Outside In.
Could anyone help?
Here's the fix:
#config/routes.rb
resources :pages, except: :show
(remove get ':id', to: 'pages#show', as: :page)
This will create the standard RESTful routes, which will create a routing structure except the show action

How to create app-wide slug routing for Rails app?
If you want to have /about etc, you'll have to generate them specifically:
#config/routes.rb
if Page.all.any?
Page.all.each do |page|
get page, to: "pages#show", id: page.id
end
end
This can also be handled with friendly_id
Have you considered using a gem that "does the work for you"? I've been using the https://github.com/thoughtbot/high_voltage gem to take care of static pages for me, without any hassle. It takes care of both routing and controller, only leaving the creation of the pages in a dedicated view/pages folder. Linking to a static page is as simple as creating a link to page_path(:name_of_the_page)
Ok, after a lot of hacking around and a helpful pointer from Rich Peck, I've got a working solution.
Routes:
resources :pages, except: :show
if Page.all.any?
Page.all.each do |page|
get "#{page.url}", to: "pages#show", as: "#{page.url}", id: page.id
end
end
Controller:
def show
#page = Page.find(params[:id])
end
Note, I've used the friendly_id gem as suggested.
To dynamically generate links:
Application controller:
def about_us
#pages = Page.all
end
helper_method :about_us
Pages helper:
def about_link(page)
link_to page.name, "/#{page.url}"
end
NB: - you need to include the / otherwise it will try to prepend the name of the controller for the page you're on (I'm not sure why).
My footer:
<% about_us.each do | page | %>
<%= about_link(page) %>
<% end %>
UPDATE:
I've had a lot of trouble deploying my app to Heroku, and I believe it's because of the pages routes.
I've now changed to a much simpler solution:
resources :pages, path: ""
and the problem's have gone away.
I have some serius problem, I created multiple language selection that works great, but the link is changing all the time.
From http://localhost:3000/en/products when I click such link
<%= link_to image_tag('en.png',:alt => 'description', :title => (I18n.t 'english') ), params.merge(:locale => :en) %>
To something like this after some time I am navigating inside app and clicking different links
http://localhost:3000/manufacturer_products?locale=en&manufacturer=Christophel
I believe that the problem is inside the routes.rb file.
This is my routes file.
root :to => 'home#index'
devise_for :admin_users, ActiveAdmin::Devise.config
ActiveAdmin.routes(self)
get "about_us/index"
namespace :products do
resources :categories do
resources :products
end
resources :products, only: :index
end
namespace :products do
resources :manufacturs do
resources :products
end
resources :products, only: :index
end
get "about/index"
match ":locale/products/search" => "products#search"
match "/contacts", to: "contacts#index"
match "/products", to: "products#index"
match "/home", to: "home#index"
match "/about_us", to: "about_us#index"
match "/news", to: "news#index"
match "/manufacturer_products", to: "manufacturer_products#index"
match '/:locale' => 'home#index'
scope "(:locale)", :locale => /en|lv|ru/ do
resources :products, :manufacturers, :categories, :news, :ActiveAdmin, :manufacturer_products
end
I understand that I have to somehow merge namespace:products route with locale route, but I have no idea to start with, If somebody could give me a tip or smth :)
Thanks
I think your routes are not a problem.
params.merge(:locale => :lv) has the function of joining 2 hashes, so you should just use something like
params[:locale] || :en
I found solution, the thing was that in routes file I didn't have right order of the routes.
This route that handles routing with locales I had at the end off file. So it didn't work.
scope "(:locale)", :locale => /en|lv|ru/ do
resources :products, :manufacturers, :categories, :news, :ActiveAdmin, :manufacturer_products, :about_us, :contacts
end
I moved this code to begining of the file and now it works perfectly. :)
I'm new to testing, and I'm having some difficulties trying to run a functional test.
I've a messages_controller, and a user_controller here.
in the routes, I've defined that the users resources has_many message resources.
Now I'm trying to run a simple test in the messages controller:
def test_index
get :index, { :user_id => 1 }
assert_template 'index'
end
But get a routing error from rails, that he cant find a route to messages. I don't want to include a route to messages only because of the tests. How can I tell the test that he must access from the /users/messages url?
the full routes.rb:
ActionController::Routing::Routes.draw do |map|
map.login 'login', :controller => :user_sessions, :action => :new
map.logout 'logout', :controller => :user_sessions, :action => :destroy
map.signin 'signin', :controller => :users, :action => :new
map.connect 'search/:action/:word', :controller => :search
map.connect 'search/:word', :controller => :search, :action => :index
map.resources :forums do |forums|
forums.resources :forum_posts, :collection => {:preview => :post }, :as => :posts do |post|
post.resources :forum_posts, :as => :reply
post.resources :reports
end
end
map.resources :newsitems, :as => :news do |news|
news.resources :comments do |comment|
comment.resources :reports
end
end
map.resource :user_sessions
map.resources :users,
:as => :profiles,
:controller => :profiles,
:has_many => [ :messages ]
map.resource :profiles
map.resource :me,
:controller => :me,
:has_many => [ :messages ]
map.resources :comments, :has_many => [ :reports ]
map.resources :forum_posts, :has_many => [ :reports ]
map.resources :reports
map.home '/', :controller => :home
map.root :controller => :home
map.namespace :admin do |admin|
admin.namespace :forum do |forum|
forum.resources :categories
forum.resources :posts
forum.resources :forums
forum.root :controller => :home
end
admin.resources :notices
admin.resources :users
admin.workflow 'workflow/:action', :controller => :workflow
admin.resources :newsitems
admin.resources :reports
admin.resources :comments
admin.root :controller => :home
end
map.connect ':controller/:action/:id'
map.connect ':controller/:action/:id.:format'
end
UPDATE
I've noticed that every functional test get a routing error. Even the simpliests ones like newsitem. I've no idea why.
I recreated your scenario in a blank rails app with the routing code and and test you specified, and it worked without a problem, as it should. I'll paste my controller code here since that's the only part you left out:
class MessagesController < ApplicationController
def index
#messages = User.find(params[:user_id]).messages
end
end
If yours is doing basically the same thing, then a routing issue could be caused by a conflict in your routing file, which is what I suspect might be the case. Can you post it? FYI, I wrote an article on testing your routes, and that would be a very good idea because it would catch routing errors early, before they interfere with controllers.
Anyway, if you can post your routes I can take a look.
UPDATE: After looking at your routes, there are a couple conflicts. You can have messages as a sub-resource of more than one other resource, but in your messages controller you're going to have to account for the possibility of either a params[:me_id] or params[:profile_id]. It looks like they're both really the user model underneath, so it can be as simple as:
#user = User.find(params[:me_id] || params[:profile_id])
and you'll probably want to abstract that out into a method you call with before_filter.
The other issue is that you have two overlapping profiles routes, and I'm not sure why. I don't think it's a routing error in the test, because tests bypass the routing engine anyway. I think it's an error in the index view, because it probably contains links to messages with improperly formatted urls. If you have a link to a message, for instance, and you have a #profile object, then you'll need to call them like this:
<%= link_to message.name, profile_message_path(#profile, #message) %>
However, if you're using non-nested paths like message_path(#message), it will fail because there are no non-nested message routes.
It was a problem in my "journey" gem. They made routes more stricter in journey 1.0.4 which only show up on "test" environment. It is good for "developement" and "production".
** Ensure you are using exactly the same parameters as declared in routes **
Either add:
get :index, :locale => "en"
or in your Gemfile update:
gem 'journey', '1.0.3'
The second solution is a workaround for time being. Ideally you should be testing your routes will all exact params. Journey 1.0.4 is a lot stricter
This is an excerpt from my config/routes.rb file:
resources :accounts do |account|
account.resource :profile, :except => [:new, :create, :destroy]
account.resources :posts,
:collection => { :fragment => :get },
:has_many => [:comments, :likes]
# even more code
end
I would like that each nested resource to be loaded from from the account namespace such as Account::PostsController instead of PostsController.
Using resources :accounts, :namespace => 'account' tries to load AccountPostsController.
Trying to nest the structure doesn't really work all that well:
map.namespace :account do |account|
..
end
The previous code will load the files from the locations I want, however it does add the namespace to the url and the generated paths so I'll have methods such as account_account_posts_url and similar paths.
Another alternative is to use something like:
account.resource :profile, :controller => 'account/profile'
I really don't like this as it involves both code duplication and forces me to remove some of the rails magic helpers.
Any thoughts and suggestions?
Changing my routes.rb and running rake routes I came up with the following:
map.resources :accounts do |accounts|
accounts.namespace :account do |account|
account.resource :profile, :except => [:new, :create, :destroy]
end
end
This gets you what you want. The correct url and pointing to account/... controller.
See Rails Routing for more detailed info and options on what can be done with Rails Routes.
So what's specifically wrong with namespacing? I think this is what you're trying to do:
map.namespace :account do |account|
account.resource :profile
end
This will try to load the controller at app/controllers/account/profiles_controller.rb and will generate routes such as account_profile_path.
Updated based on comment:
map.resources :accounts do |account|
account.resource :profile
end
Will give you /accounts/22/profile.
