I'm a new rails developer making an application where I have a user profile like: localhost:3000/posts routing to localhost:3000/Charles where Charles is the username.
So the code I'm using to do this looks like:
routes.rb
match "/:username" => "posts#index"
and then in my controller:
#user = User.find_by_username params[:username]
#search = Post.search do |query|
query.fulltext params[:search]
query.with(:user, #user.id)
end
this works great just for the post index, but I'd like to have posts/18 (for example) be routed to /username/posts/18.
So basically, I'm asking if there's a way to do something like this:
match "/:username" => "posts#index" do
resources :posts
end
Thanks for all help!
This
scope '/:username' do
resources :posts
end
produces what you want:
posts GET /:username/posts(.:format) posts#index
POST /:username/posts(.:format) posts#create
new_post GET /:username/posts/new(.:format) posts#new
edit_post GET /:username/posts/:id/edit(.:format) posts#edit
post GET /:username/posts/:id(.:format) posts#show
PATCH /:username/posts/:id(.:format) posts#update
PUT /:username/posts/:id(.:format) posts#update
DELETE /:username/posts/:id(.:format) posts#destroy
Try
scope ':username' do
resources :posts
end
bundle exec rake routes
posts GET /:username/posts(.:format) posts#index
POST /:username/posts(.:format) posts#create
new_post GET /:username/posts/new(.:format) posts#new
edit_post GET /:username/posts/:id/edit(.:format) posts#edit
post GET /:username/posts/:id(.:format) posts#show
PUT /:username/posts/:id(.:format) posts#update
DELETE /:username/posts/:id(.:format) posts#destroy
match "/:username/posts/:id" => "posts#show"
But that won't really help when you need to edits and such. So, try:
scope "/:username" do
resources :posts
end
That failing:
scope "/:username" do
get '' => "posts#index"
get 'posts/:id' => "posts#show"
end
Hopefully the first will work. Haven't tried it myself so forgive me, but I'm pretty sure that, in general, scope is what you want.

I'm totally new on Ruby, I need to create route get which will write dynamically text = "About Us"
about.html.erb code:
<h1><%= #title %></h1>
index.html.erb code:
<h1>Index</h1>
Routes code:
Rails.application.routes.draw do
root 'posts#index'
get 'about' => 'pages#about'
end
In the folder controllers I have defined pages_controller.rb and posts_controller.rb,pages with simple function about and posts with function index
In the folder views/pages I have about.html.erb and views/posts index.html.erb
The problem is when I run it, it writes message only from index and not from about.html.erb
Rake routes message:
$ rake routes
Prefix Verb URI Pattern Controller#Action
root GET / posts#index
about GET /about(.:format) pages#about
posts GET /posts(.:format) posts#index
POST /posts(.:format) posts#create
new_post GET /posts/new(.:format) posts#new
edit_post GET /posts/:id/edit(.:format) posts#edit
post GET /posts/:id(.:format) posts#show
PATCH /posts/:id(.:format) posts#update
PUT /posts/:id(.:format) posts#update
DELETE /posts/:id(.:format) posts#destroy
Since you want to call the about action and you named it about in your routes.rb file, you have to point your browser to:
localhost:3000/about
You also have to set your #title variable to something in the pages#about action.
I have two controllers offers and posts.
In routes.rb I've got the following...
resources :offers
get "/posts" => "posts#index"
post "/posts" => "posts#create"
get "/posts/new" => "posts#new"
get "/posts/:id/edit" => "posts#edit"
get "/posts/:id" => "posts#show"
put "/posts/:id" => "posts#update"
patch "/posts/:id" => "posts#update"
delete "/posts/:id" => "posts#destroy"
It was my understanding that these two ways of doing the routing are identical in their operation. Or put another way resources :offers is a just shortcut for writing out each route.
My problem however is when I do a rake routes I get...
Prefix Verb URI Pattern Controller#Action
offers GET /offers(.:format) offers#index
POST /offers(.:format) offers#create
new_offer GET /offers/new(.:format) offers#new
edit_offer GET /offers/:id/edit(.:format) offers#edit
offer GET /offers/:id(.:format) offers#show
PATCH /offers/:id(.:format) offers#update
PUT /offers/:id(.:format) offers#update
DELETE /offers/:id(.:format) offers#destroy
posts GET /posts(.:format) posts#index
POST /posts(.:format) posts#create
posts_new GET /posts/new(.:format) posts#new
GET /posts/:id/edit(.:format) posts#edit
GET /posts/:id(.:format) posts#show
PUT /posts/:id(.:format) posts#update
PATCH /posts/:id(.:format) posts#update
DELETE /posts/:id(.:format) posts#destroy
The 'shorthand' offers routes have a four prefixes assigned to them, whereas the longhand posts routes have only two.
So my questions are:
Why don't all the routes get given prefixes when written out longhand?
Is there any way of assigning a prefix to a route when writing them out longhand?
You can assign a prefix to a route when writing them out longhand by doing:
root 'pages#index', as: :home, where :home is your prefix.

Generating Paths and URLs from Code
I have created a new action in Posts controller, However, it seems that I can not access it.
the action name is 'kill' , so when I type in my browser, localhost:3000/posts/kill
I get the following error : Couldn't find Pad with id=kill
Extracted source (around line #18
def show
#post_selected = Post.find(params[:id])
#posts = Post.all
end
In my routes.rb
resources :posts
match ':controller(:action(/:id))', :via => [:get, :post]
match "/pads/modifier" => "pads#modifier", :via => [:get]
and when I type rake routes , this is what i get
Prefix Verb URI Pattern Controller#Ac
posts GET /posts(.:format) posts#index
POST /posts(.:format) posts#create
new_post GET /posts/new(.:format) posts#new
edit_post GET /posts/:id/edit(.:format) posts#edit
post GET /posts/:id(.:format) posts#show
PATCH /posts/:id(.:format) posts#update
PUT /posts/:id(.:format) posts#update
DELETE /posts/:id(.:format) posts#destroy
root GET / posts#welcome
GET|POST /:controller(:action(/:id))(.:format) :controller#:
posts_modifier GET /posts/modifier(.:format) posts#modifier
How do I generate a path to get my newly created action 'kill'?
=========================================================
Update #1 : Solved,
In addition to the answer below, I could make it happen with the following code
resources :posts, controller: 'posts' do
get 'posts/:action', to: 'posts#:action'
end
===========================================================
get 'posts/kill', to: 'posts#kill'
undefined method `post_comments_path' for #<#<Class:0x4e6ec28>:0x4e6e3d0>
I am getting this error while I am going to create a comment associated with the posts.
<%= form_for([#post, #post.comments.build]) do |f| %>
Above is the section of the form where i am getting the error..
My code in comments controller:
def create
#post = Post.find (params[:post_id])
#comment = #post.comments.create(params[:comments].permit(:commenter, :body))
redirect_to post_path(#post)
end
Please point out where I am wrong. I am a newbie to ruby on rails.
my routes.rb:
Blog::Application.routes.draw do
resources :posts
resources :comments
root to:"welcome#index"
get "welcome/index"
my rake routes:
posts GET /posts(.:format) posts#index
POST /posts(.:format) posts#create
new_post GET /posts/new(.:format) posts#new
edit_post GET /posts/:id/edit(.:format) posts#edit
post GET /posts/:id(.:format) posts#show
PATCH /posts/:id(.:format) posts#update
PUT /posts/:id(.:format) posts#update
DELETE /posts/:id(.:format) posts#destroy
comments GET /comments(.:format) comments#index
POST /comments(.:format) comments#create
new_comment GET /comments/new(.:format) comments#new
edit_comment GET /comments/:id/edit(.:format) comments#edit
comment GET /comments/:id(.:format) comments#show
PATCH /comments/:id(.:format) comments#update
PUT /comments/:id(.:format) comments#update
DELETE /comments/:id(.:format) comments#destroy
root GET / welcome#index
welcome_index GET /welcome/index(.:format) welcome#index
My edited routes.rb ::
Blog::Application.routes.draw do
resources :post do
resources :comments
end
root to:"welcome#index"
get "welcome/index"
end
You try to use nested resources, but you didn't define it in routes.rb. You should have:
resources :posts do
resources :comments
end
And this should work.
I'am working on sixrevision.com tutorial “How to Create a Blog from Scratch Using Ruby on Rails” . I try to convert It from rails 2.x to 3.x. When I run localhost:3000 I get this:
Routing Error
uninitialized constant PostController
Try running rake routes for more information on available routes.
Rake Routes shows me this:
posts GET /posts(.:format) posts#index {:has_many=>:comments}
POST /posts(.:format) posts#create {:has_many=>:comments}
new_post GET /posts/new(.:format) posts#new {:has_many=>:comments}
edit_post GET /posts/:id/edit(.:format) posts#edit {:has_many=>:comments}
post GET /posts/:id(.:format) posts#show {:has_many=>:comments}
PUT /posts/:id(.:format) posts#update {:has_many=>:comments}
DELETE /posts/:id(.:format) posts#destroy {:has_many=>:comments}
/:controller/:action/:id(.:format) :controller#:action
/:controller/:action/:id.:format :controller#:action
root / post#index
My routes.rb file:
Myblog::Application.routes.draw do
resources :posts, :has_many => :comments
match ':controller/:action/:id'
match ':controller/:action/:id.:format'
root :to => "post#index"
end
Anybody got any idea? Thanks for intrest & help!
In routes.rb file:
resources :posts do
resources :comments
end
In your routes.rb you should have:
root :to => 'posts#index'
because you do not have (probably) PostController but PostsController
