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 try to fill twice id in url, but when i send params twice id just one id fill the url id.
My route :
namespace :admin do
resources :stores
get "/:id/new_items"=> 'stores#new_items', as: :store_new_items
post "/:id/create_items"=> 'stores#create_items', as: :store_create_items
get "/:id/show_items/:id"=> 'stores#show_items', as: :store_show_items
get "/:id/items/:id/new_items_sub" => 'stores#new_items_sub', as: :store_new_items_sub
post "/:id/items/:id/create_items_sub" => 'stores#create_items_sub', as: :store_create_items_sub
get "/:id/items/:id/show_items_sub/:id" => 'stores#show_items_sub', as: :store_show_items_sub
end
my view :
<%= link_to "add new items", admin_store_new_items_sub_path(#store.id, #items.id), :class=> "btn" %>
i hope my url like this :
http://localhost:3000/admin/#{store.id}/items/#{items.id}/new_items_sub
but i get same id like this :
http://localhost:3000/admin/#{store.id}/items/#{store.id}/new_items_sub
please tell me when i'm wrong? thanks
you have to create neseted routes for that .have a look at
http://guides.rubyonrails.org/routing.html#nested-resources
for example
resources :publishers do
resources :magazines do
resources :photos
end
end
will accept routes /publishers/1/magazines/2/photos/3
Your params should be unique, so you can't pass more than one different :id params. Instead. you can do something like:
get '/:store_id/show_items/:id', as: :store_show_items
and in view:
<%= link_to 'show items', store_show_items_path(#store.id, #item.id) %>
Also, you should read more about Resources and Nested Resources in Rails, there's probably no need to complicate your life by creating each route independently.
You could refactor this to use nested routes like this (you may have to change controller method names):
namespace :admin do
resources :stores do
resources :items, :only => [:new, :create, :show] do
resources :subs, :only => [:new, :create, :show]
end
end
end
This would give you a few url helpers like this: new_store_item_sub_path(#store.id, #item.id) for the new action and store_item_sub_path(#store.id, #item.id, #sub.id) for the show action.
Run rake routes to see what helpers and routes you have access to.
Have a look here to find out more about nested routes.
Your code can be DRYed up significantly. Hopefully this works; might need some tweaking:
namespace :admin do
resources :stores do
member do
get :new_items, as: :store_new_items
post :create_items, as: :store_create_items
end
get "show_items/:id"=> 'stores#show_items', as: :store_show_items
resources :items do
get :new_items_stub => 'stores#new_items_sub', as: :store_new_items_sub
post :create_items_stub => 'stores#create_items_sub', as: :store_create_items_sub
get "show_items_sub/:id" => 'stores#show_items_sub', as: :store_show_items_sub
end
end
end

Nested Resources
The crux of your issue is that you're trying to pass the :id param twice
Fortunately, Rails has a solution to this, in the form of Nested Resources. These work by taking the "parent" id and prepending a singular prefix, such as :store_id, allowing you to use the :id param for another set of methods
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 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.
