I've created custom routes to route to News model
resources :news, only: [:index] do
collection do
get 'page/:page', action: :index
end
end
get "news/:id(/p/:p)", to: 'news#show', as: 'news'
generate url like this
http://localhost:3000/news/4/page/2 index.html.erb is right
and show.html.erb
<%= link_to 'news', news_path(#news, '2')%>
I hope generate url http://localhost:3000/news/4/p/2
but generate http://localhost:3000/news/4?p=2
I think you've got a route conflict, change this:
get "news/:id(/p/:p)", to: 'news#show', as: 'news'
to this:
get "news/:id(/p/:p)", to: 'news#show', as: 'news_page'
and the use this link:
<%= link_to 'News', news_page_path(#news, '2')%>

I want to add link to friends list but i get routing error
No route matches {:action=>"friend_list", :controller=>"users_controller"}
users_controller
def friend_list
#frnds = User.find_friends(current_user)
end
routes
devise_for :users
resources :users do
member do
get :follow
get :unfollow
get :show
end
match 'users/:id/friend_list' => 'users#friend_list', via: [:get]
link
<li><%= link_to "Friends", :controller => :users_controller, :action => :friend_list%></li>
end
match 'users/:id/friend_list' => 'users#friend_list', via: [:get]
root 'home#front'
instead of member block use collection block like this
resources :users do
collection do
get "follow"
get "unfollow"
get "show"
end
end
member block will append :id in routing while collection block will allow you add custom routes in resource routes
in link_to use this
<%=link_to "Friends", controller: "users", action: "friend_list"%>
I've created a controller Pages and some actions for simple pages (contact us, for instance), then I went to routes.rb and created a route to allow users to go directly to /contactus, instead of /pages/contactus.
How can I point link_to to the action, but still getting the right route url?
get :contact_us, to: 'pages#contact_us'
or
get :contact_us, controller: :pages, action: :contact_us
this will generate path contact_us_path or url contact_us_url
HEARE MORE ABOUT ROUTES IN RAILS
#config/routes.rb
resources :pages, path: "", only: [] do #-> has to be above everything in routes file
collection do
get :contact_us #-> url.com/contact_us
get :about #-> url.com/about
end
end
root ...
You'd link to it as follows:
<%= link_to "Contact", pages_contact_us_path %>
You can do this:
get '/contactus', to: 'pages#contactus'
Your link can be:
<%= link_to "Contact Us", contactus_path %>
For more information, see: http://guides.rubyonrails.org/routing.html#connecting-urls-to-code
This is the syntax for a simple route using the contactus action in the pages controller:
get '/contactus' => 'pages#contactus'
or if you want a simpler name for your path:
get '/contactus' => 'pages#contactus', as: :contact
I have this in my routes.rb:
resources :profiles, :only => :show
I'm building a link like this: <%= link_to( "profile", profile_path(13)) %> and it's giving me a url of /profile?id=13 - I want it to give me /profiles/13 (as that one works).
What am I doing wrong?
Rake routes result for this resource:
GET /profiles/:id(.:format) profiles#show
Here is my link_to
<%= link_to sub_category.name, controller: :posts, action: :product, id: "#{sub_category.slug}-#{sub_category.id}" %>
Which is pointing to the url
http://localhost:3000/posts/product/fifith-category-s-sub-category-2
I need the url as follows
http://localhost:3000/fifith-category-s-sub-category-2
How can i do it.
my route.rb
resources :posts
match ':controller(/:action(/:id))(.:format)', via: [:get,:post]
what #MarekLipka suggests is correct but defining your routes like this will take up all the single level namespace in your app i.e. "/anything" will route by default to posts#product.
I recommended using some form of identifier to figure out which routes should go to posts#product. What will work for you depends on why you want to do this. Couple of options are:
Use a short namespace:
scope '/pp' do
get ':id', to: 'posts#product
end
# "/pp/:id" routes to 'posts/product'
# pp is a random short name I picked, it could be anything
# link
<%= link_to sub_category.name, "pp/#{sub_category.slug}-#{sub_category.id}" %>
Use a constraint:
get ':id', to: 'posts#product`, constraints: { :id => /sub\-category/ }
# only id's with 'sub-cateogry' route to 'posts/product'
# link (assuming that sub_category.slug has 'sub-category' words in it)
<%= link_to sub_category.name, "#{sub_category.slug}-#{sub_category.id}" %>
If you want path /:id match your posts#product, you should have something like this in your routes:
resources :posts
match ':id', to: 'posts#product`, via: :get
match ':controller(/:action(/:id))(.:format)', via: [:get, :post]
I'm trying to post to my registration controller using a link_to link.
I have <%= link_to "Register for Period", registration_path(period_id: period.id), :method => :post %>
Which generates a link like: http://localhost:3000/registrations/6?period_id=25 where the 6 is the event_id. I need to save the period_id and the user_id to the registration database.
I get the following error in the browser: No route matches [POST] "/registrations/6"
What am I doing wrong?
routes:
Mavens::Application.routes.draw do
devise_for :users
resources :events
resources :periods
resources :products
resources :cart_rows
resources :product_requests
resources :inqueries
resources :registrations
match '/profile', to: 'static_pages#profile'
root :to => 'static_pages#home'
get "static_pages/home"
get "static_pages/about"
end
If you put in your routes.rb:
resources :registrations do
member do
post :save_period
end
end
And in your link:
<%= link_to "Register for period",
save_period_registration_path(id: #registration.id, period_id: period.id), :method => :post %>
You will have a route that matches your resquest.
When you only have a resources :registrations rule on your routes.rb, only the default restful routes are created, and there is no POST to a single resource created by default.
I believe you will have to read something about the CSRF token, because if you have a protect_from_forgery on your application_controller, probably this POST request from a single link would not work.
Your routes.rb is missing the required path. It IS a standard path, so adding 'resources :registrations' would work.
If more complex, post your routes.rb and we can tell what to add.
