I have an app with subdomains for various people that all share the same domain (i.e. www.liz.domain.com, www.anthony.domain.com, etc.). I need to create links from one subdomain to the main domain and back, but can't figure out how to make it work. My routes stand like this:
Rails.application.routes.draw do
constraints subdomain: 'liz' do
scope module: 'liz', as: 'liz' do
get 'home/index'
root 'home#index'
resources :inquiries
get 'services/hire'
get 'services/dev'
get 'services/design'
get 'services/branding'
get 'services/portfolio'
end
end
constraints subdomain: 'anthony' do
scope module: 'anthony', as: 'anthony' do
get 'home/index'
root 'home#index'
end
end
get 'home/index'
root 'home#index'
end
And when I rake routes it turns out like this:
Prefix Verb URI Pattern Controller#Action
liz_home_index GET /home/index(.:format) liz/home#index {:subdomain=>"liz"}
liz_root GET / liz/home#index {:subdomain=>"liz"}
liz_inquiries GET /inquiries(.:format) liz/inquiries#index {:subdomain=>"liz"}
POST /inquiries(.:format) liz/inquiries#create {:subdomain=>"liz"}
new_liz_inquiry GET /inquiries/new(.:format) liz/inquiries#new {:subdomain=>"liz"}
edit_liz_inquiry GET /inquiries/:id/edit(.:format) liz/inquiries#edit {:subdomain=>"liz"}
liz_inquiry GET /inquiries/:id(.:format) liz/inquiries#show {:subdomain=>"liz"}
PATCH /inquiries/:id(.:format) liz/inquiries#update {:subdomain=>"liz"}
PUT /inquiries/:id(.:format) liz/inquiries#update {:subdomain=>"liz"}
DELETE /inquiries/:id(.:format) liz/inquiries#destroy {:subdomain=>"liz"}
liz_services_hire GET /services/hire(.:format) liz/services#hire {:subdomain=>"liz"}
liz_services_dev GET /services/dev(.:format) liz/services#dev {:subdomain=>"liz"}
liz_services_design GET /services/design(.:format) liz/services#design {:subdomain=>"liz"}
liz_services_branding GET /services/branding(.:format) liz/services#branding {:subdomain=>"liz"}
liz_services_portfolio GET /services/portfolio(.:format) liz/services#portfolio {:subdomain=>"liz"}
anthony_home_index GET /home/index(.:format) anthony/home#index {:subdomain=>"anthony"}
anthony_root GET / anthony/home#index {:subdomain=>"anthony"}
home_index GET /home/index(.:format) home#index
root GET / home#index
I've tried using a <%= link_to "Liz's Page", liz_root_path(subdomain: 'liz') %> or <%= link_to "Liz's Page", liz_root_path %> from the main domain (without a subdomain), but neither links to the subdomain.
Similarly, I've tried <%= link_to "Main Page", root_path %> from a page inside a subdomain and it just links to the subdomain's home, not the site root.
Can anyone straighten me out on how to link back and forth between subdomains/main domains?
I eventually changed these from path to url to solve the problem.
This way <%= link_to "Liz's Page", liz_root_path(subdomain: 'liz') %> became <%= link_to "Liz's Page", liz_root_url(subdomain: 'liz') %> and worked fine.

I am beginner to ror, I am trying dynamic page in my application, while I click the about link in my application I got a routing error(as said in title). Here is my routes.rb file
Rails.application.routes.draw do
devise_for :users
resources :userdetails do
collection {post :import}
end
# For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
root to: "userdetails#index"
get 'about', to:'userdetails#about'
devise_scope :users do
get 'sign_in', to: 'devise/sessions#new'
get 'sign_out', to: 'devise/sessions#destroy'
end
end
here is index.html.erb file:
<div class="topnav">
Home
News
Contact
<a href="about_path" data-method = "get" >About Us</a>
...
</div>
Please help me identify my mistake.....
your routes says: -
get '/about', to: 'userdetails#about', as: :user_about
so according to this
About Us
Instead of this you can use rails view helper which fill convert this to html anchor tag: -
<%= link_to 'About Us', user_about_path%>
As you are beginner so you should go though this rails Routing for better clarification.
Note: - by default link is GET type http verb so you don't need to mention data-method = "get"
and you can see all your routes at console by running command rake routes
When you run rails routes or rake routes it will generate like this
about GET /about(.:format) userdetails#about
That means your path is about_path then you can call out like this
About Us
or like this HTML
About Us
or like this .erb
<%= link_to 'About Us', about_path %>
While your routes like exist
get 'about', to:'userdetails#about'
Here you have defined method get that's why this is unnecessary to HTML call out data-method = "get".
Hope it will work
I am working an an Rails app. The problem I am have is when I cycle between my about and contact pages. I always get the error
No route matches [GET] "/pages/pages/about"
or
No route matches [GET] "/pages/pages/contact"
I'm trying to change the routes my nav bar partial the tag href to "/about" but the same error occur. it ask me to use the command rake routes and it shows
$ rake routes
restaurants GET /restaurants(.:format) restaurants#index
POST /restaurants(.:format) restaurants#create
new_restaurant GET /restaurants/new(.:format) restaurants#new
edit_restaurant GET /restaurants/:id/edit(.:format) restaurants#edit
restaurant GET /restaurants/:id(.:format) restaurants#show
PUT /restaurants/:id(.:format) restaurants#update
DELETE /restaurants/:id(.:format) restaurants#destroy
pages_about GET /pages/about(.:format) pages#about
root / restaurants#index
pages_contact GET /pages/contact(.:format) pages#contact"
can some one please help me!!
Your about and contact are under the url /pages/about and /pages/contact but the URL you are accessing is /pages/pages/about which doesn't exist.
You can see in the rake routes, the possible urls in the system.
you need to have the link in your web app as
<%= link_to 'About', pages_about_path %>
<%= link_to 'Contact', pages_contact_path %>
in your routes you can do something like
#config/routes.rb
ClientCruiser::Application.routes.draw do
....
match "contact" => "pages#contact", :as => :contact, via: :all
match "about" => "pages#about", :as => :about, via: :all
....
root :to => 'pages#index'
end
The output of this
contact /contact(.:format) pages#contact
about /about(.:format) pages#about
root GET / pages#index
the way you would make the call would be
<%= link_to about_path, "About", class: '' %>
<%= link_to contact_path, "Contact", class: '' %>
I'm a beginner in ruby on rails and was following an online tutorial. I got lost immediately on routes. Every time I try to go to my url 'pages/help' an error is displaying in the browser "The action 'show' could not be found for PagesController". I have a ruby partitions named _header that contains these codes:
<header>
<%= link_to logo, root_path %>
<ul class="nav nav-tabs">
<li class="active">
<%= link_to "Home |", root_path %>
</li>
<li><%= link_to "Help |", pages_help_path %></li>
<li><%= link_to "Sign In", '#'%></li>
</ul>
</header>
And when I try to click the "Help" link the error occurs.
My routes.rb contains just these codes:
BakeShop::Application.routes.draw do
resources :pages
root :to => 'pages#home'
#match '/help', :to => 'pages#help'
get "pages/help"
end
and i have a PagesController with only these codes:
class PagesController < ApplicationController
def home
end
def help
end
end
and when I run 'rake routes' the lists contained are:
pages GET /pages(.:format) pages#index
POST /pages(.:format) pages#create
new_page GET /pages/new(.:format) pages#new
edit_page GET /pages/:id/edit(.:format) pages#edit
page GET /pages/:id(.:format) pages#show
PATCH /pages/:id(.:format) pages#update
PUT /pages/:id(.:format) pages#update
DELETE /pages/:id(.:format) pages#destroy
root GET / pages#home
pages_help GET /pages/help(.:format) pages#help
And I certainly have home.html.erb and help.html.erb created in my views folder. And the twist is that when I create a 'show.html.erb' in my views folder and create an action in my pages controller named 'show', the error disappears and links to .
So what I'm saying is, can anyone explain this? Why is rails looking for 'show' action, and not 'help' action, that I didn't define
One thing to understand about routes in Rails is that the order of routes specified is very important. In your config/routes.rb file you have routes specified in the following order:
resources :pages
root :to => 'pages#home'
get "pages/help"
So, what this does is, matches the routes defined with resources :pages first. As you can see in the output of rake routes, Rails generated the following routes for that specific line i.e. resources :pages:
pages GET /pages(.:format) pages#index
POST /pages(.:format) pages#create
new_page GET /pages/new(.:format) pages#new
edit_page GET /pages/:id/edit(.:format) pages#edit
page GET /pages/:id(.:format) pages#show
PATCH /pages/:id(.:format) pages#update
PUT /pages/:id(.:format) pages#update
DELETE /pages/:id(.:format) pages#destroy
Also note that pages_help GET /pages/help(.:format) pages#help is at the bottom of that list. So what is happening is when you navigate to /pages/help, Rails finds the first GET request that matches that pattern, in this case:
page GET /pages/:id(.:format) pages#show
And since you don't have the show action defined, it's throwing that error "The action 'show' could not be found for PagesController".
So, to solve you specific problem without the show action and show.html.erb, you can rearrange the config/routes.rb as follows:
BakeShop::Application.routes.draw do
get "pages/help" # Move this line before resources :pages
resources :pages
root :to => 'pages#home'
end
Moving get "pages/help" will ensure that for your url /pages/help this route will match and your help.html.erb will be rendered.
Update:
How it matched pages/show?
# In the comments below where .format is used think of various extensions just as html, js, json, xml etc but not required.
pages GET /pages(.:format) pages#index
# Matches /pages, /pages.format
new_page GET /pages/new(.:format) pages#new
# Matches /pages/new, /pages/new.format
edit_page GET /pages/:id/edit(.:format) pages#edit
# Matches /pages/1/edit, /pages/1/edit.format or pages/anything/edit.format. Note that the edit in the end is required here,the only variable here is id and format
page GET /pages/:id(.:format) pages#show
# Matches /pages/1, /pages/anything, /pages/1.format, /pages/anything.format. In the question /pages/help matches.
You have to enable the default root in your routes.rb.
Update routes.rb:-
BakeShop::Application.routes.draw do
resources :pages
root :to => 'pages#home'
#match '/help', :to => 'pages#help'
get "pages/help" #this is not required
match ':controller(/:action(/:id(.:format)))'
end
The problem here is that the route for the show action (page_path) and the route for your pages_help_path conflict. If you simply move the line get "pages/help" before the line resources :pages it will work as you intend.
Routes.rb:
BakeShop::Application.routes.draw do
get "pages/help"
resources :pages
root :to => 'pages#home'
end
I have a basic homepage with a link that I would like to go to businesses/index.html.erb
<%= link_to("Go to businesses index page", {:controller=>"businesses", :action =>"index"}) %>
When I click on this link I get a routing error:
No route matches {:action=>"show", :controller=>"businesses"}
My routes.rb file looks like:
RailsProject::Application.routes.draw do
get "welcome/index"
root :to => 'welcome#index'
get "businesses/index"
resources :businesses
end
and rake routes gets me:
welcome_index GET /welcome/index(.:format) welcome#index
businesses GET /businesses(.:format) businesses#index
POST /businesses(.:format) businesses#create
new_business GET /businesses/new(.:format) businesses#new
edit_business GET /businesses/:id/edit(.:format) businesses#edit
business GET /businesses/:id(.:format) businesses#show
PUT /businesses/:id(.:format) businesses#update
DELETE /businesses/:id(.:format) businesses#destroy
root / welcome#index
businesses_index GET /businesses/index(.:format) businesses#index
I am using rails version 3.2
The problem was that in my businesses/index there was a line reading
<%= link_to 'show', business_path %>
that should have been
<%= link_to 'show', business_path(business) %>
This one is a two-parter. Initially I had just one controller:
$ rails generate controller home index
...and I made that my root.
Recently, though, I wanted to get the database involved. So I made a scaffold called Daily and switched the root to dailies#index instead of home#index.
That worked just fine. Everything seems to be working fine.
...only problem is that I want to use home#index for something else... but now I have no way to link to it.
This is my routes.rb file:
LiquidAdmin::Application.routes.draw do
resources :dailies
devise_for :users
get '/auth/:provider/callback', to: 'sessions#create'
get "home/bandwall"
get "home/index" :to => "home#index"
# get "dailies/index"
root :to => "dailies#index"
and these are my routes:
home_index GET /home/index(.:format) home#index
I've tried.
<% link_to "Home", home_path %>
<% link_to "Home", home_index %>
<% link_to "Home", home/index %>
Nothing will get me back to that file... even though it was working just fine when it was the root.
Now all of this could've been avoided if "Plan A" had worked...
Plan A was just to make this Daily scaffold and do something like:
<% #dailies.each do |daily| %>
This worked as a link from the Daily index... but not as a link from home#index. Which is why I switched the root. I was getting annoyed and it was easier.
So my questions: 1. How do I link to the old home#index? 2. How should I have queried the dailies tables from home#index?
Assuming you have a Daily model.
routes.rb
resources :dailies
get "home/index"
Running rake routes:
dailies GET /dailies(.:format) dailies#index
POST /dailies(.:format) dailies#create
new_daily GET /dailies/new(.:format) dailies#new
edit_daily GET /dailies/:id/edit(.:format) dailies#edit
daily GET /dailies/:id(.:format) dailies#show
PUT /dailies/:id(.:format) dailies#update
DELETE /dailies/:id(.:format) dailies#destroy
home_index GET /home/index(.:format) home#index
app/controllers/dailies_controller.rb
class DailiesController
def index
#dailies = Daily.all
end
end
app/views/dailies/index.html.erb
<%= link_to "Home", home_index_path %>
<% #dailies.each do |daily| %>
<%= link_to 'A daily', daily_path(daily) %>
<% end %>
