I'm a real beginner of rails.
Can I get multiple routes from one controller + many actions?
For example,
resources :something
get "something#index", "something#show", "something#update"...etc.
I'm just curious if there is a command to get route name from the actions.
For example, in a controller named "pledges",
class PledgesController < ApplicationController
def home
end
def abc
end
def defg
end
def hijk
end
end
Can any commands get "pledges#home", "pledges#abc", "pledges#defg","pledges#hijk" ?
To add custom, "non-RESTful" routes to a resource, you could do the following:
resources :pledges do
collection do
get :foo
end
member do
put :bar
end
end
collection-defined routes will produce results against Pledge as a whole – think the index route.
member-defined routes will produce results against an instance of Pledge – think the show route.
This would produce the following routes for you:
foo_pledges GET /pledges/foo(.:format pledges#foo
bar_pledge PUT /pledges/:id/bar(.:format) pledges#bar
pledges GET /pledges(.:format) pledges#index
POST /pledges(.:format) pledges#create
new_pledge GET /pledges/new(.:format) pledges#new
edit_pledge GET /pledges/:id/edit(.:format) pledges#edit
pledge GET /pledges/:id(.:format) pledges#show
PATCH /pledges/:id(.:format) pledges#update
PUT /pledges/:id(.:format) pledges#update
DELETE /pledges/:id(.:format) pledges#destroy
You will have to define all of the custom actions, if there are not restful (but I would highly recommend that you follow the rest conventions). For example:
get 'pledges' => 'abc'
post 'pledges' => 'defg'
put 'pledges' => 'hijk

I have a reports controller with several actions, one for each kind of report.
I was planning to have them route like this:
/reports/:report_type
I'd like the report_type string fragment to be used as the controller name so that I can have a single route to handle all of them, something like this:
get 'reports/:rpt_type' => "reports#:rpt_type"
...that would resolve to this, as an example:
get 'reports/song_performers' => 'reports#song_performers'
Is this possible, and if so, how?
Yes, it is. You could handle this in the controller, rather than the routes.rb file:
# reports_controller.rb
def show
send(params[:rpt_type])
end
private
def song_performers
# do stuff
end
def other_type
# do other stuff
end
# in routes.rb
get 'reports/:rpt_type', to: 'reports#show'
I have some problems with routing custom controller actions
Routes:
resources :clans do
get 'leave' =>'clan#leave_clan'
get 'dismiss' =>'clan#dismiss_clan'
get 'kick_from_clan/:user_id' =>'clan#kick'
get 'invite/:user_id' =>'clan#invite'
get 'join' =>'clan#join'
end
namespace :admin do
resources :clans
resources :users
end
I know i have clans both in admin namespace and also without but that is how i need it, actions are completely different in them.
And I use a generated route as clan_join_path(clan).
This action results in the next error:
uninitialized constant ClanController
Directory structure:
/app
/controller
/admin
/ClansController.rb
/ClansController.rb
EDIT:
Also invite and kick routes are not generated as expected.
*no path* GET /clans/:clan_id/kick_from_clan/:user_id(.:format) clan#kick
*no path* GET /clans/:clan_id/invite/:user_id(.:format) clan#invite
Any suggestion to the edit part?
You're defining a resource called clans and I presume you have a controller also called ClansController (note the puralization). If you don't have this controller, you'll be wanting to create it.
You probably therefore need to pluralize your routes:
resources :clans do
get 'leave' =>'clans#leave_clan'
get 'dismiss' =>'clans#dismiss_clan'
get 'kick_from_clan/:user_id' =>'clans#kick'
get 'invite/:user_id' =>'clans#invite'
get 'join' =>'clans#join'
end
Also make sure your controller is named clans_controller.rb (pluralized).
You can use member do ... end to properly route based on type of action
resources :clans do
member do
get :leave
get :dismiss
#etc
end
end
This will define the routes as clans/:id/leave clans/:id/dismiss
Check if your clans_controller.rb is intentionally not plural.
resources :clans do
get 'leave' =>'clans#leave_clan'
get 'dismiss' =>'clans#dismiss_clan'
get 'kick_from_clan/:user_id' =>'clans#kick'
get 'invite/:user_id' =>'clans#invite'
get 'join' =>'clans#join'
end
app/controllers/clans_controller.rb
class ClansController < ApplicationController
end
I am using rails 4.1 with Casein CMS: https://github.com/russellquinn/casein
I have setup a Post Model, view and controllers within casein, but I would like to access the Posts outside of casein, possibly under another route called blog
I have tried and tried reworking my routes and controllers, and have an array of errors to list. Someone here might know just the trick to get this working, and was hoping some could help me, or at least explain to me what should be happening or what I might be doing wrong.
What Casein adds to the routes is this:
#Casein routes
namespace :casein do
resources :posts
end
And I'd like to match the index and show actions to => /blog. How might I write this correctly in my routes.rb.
My controller, I have basically extracted the actions from the Casein's PostsController, and along with including the Casein Module have tried to simple list all the posts.
Here is what my blogs_controller's index action looks like:
class BlogsController < ApplicationController
module Casein
def index
#casein_page_title = 'Posts'
#posts = Post.order(sort_order(:title)).paginate :page => params[:page]
end
end
end
By the end I'd also like to take blogs to blog, but I think can take it from there, but if anyone has any suggestions, that would be much appreciated.
You might be asking for this, but your question is not very clear.
If you want to have the following routes and use the same controller for each.
Prefix Verb URI Pattern Controller#Action
casein_posts GET /casein/posts(.:format) casein/posts#index
POST /casein/posts(.:format) casein/posts#create
new_casein_post GET /casein/posts/new(.:format) casein/posts#new
edit_casein_post GET /casein/posts/:id/edit(.:format) casein/posts#edit
casein_post GET /casein/posts/:id(.:format) casein/posts#show
PATCH /casein/posts/:id(.:format) casein/posts#update
PUT /casein/posts/:id(.:format) casein/posts#update
DELETE /casein/posts/:id(.:format) casein/posts#destroy
blog GET /blog(.:format) casein/posts#index
GET /blog/:id(.:format) casein/posts#show
then your config/routes.rb file should contain
namespace :casein do
resources :posts
end
get '/blog', to: 'casein/posts#index'
get '/blog/:id', to: 'casein/posts#show'
And you need your controller to be app/controllers/casein/posts_controller.rb
But I'd really strongly encourage you to use 2 different controllers, and a concern for the shared methods
I'm having a bit of a problem with route namespaces that I've not encountered before. This is actually a part of some gem development I'm doing - but i've reworked the problem to fit with a more generic rails situation.
Basically, I have a namespaced route, but I want it to direct to a generic (top-level) controller.
My controller is PublishController, which handles publishing of many different types of Models - which all conform to the same interface, but can be under different namespaces. My routes look like this:
# config/routes.rb
namespace :manage do
resources :projects do
get 'publish' => 'publish#create'
get 'unpublish' => 'publish#destroy'
end
end
The problem is that this creates the following routes:
manage_project_publish GET /manage/projects/:project_id/publish(.:format) {:controller=>"manage/publish", :action=>"create"}
manage_project_unpublish GET /manage/projects/:project_id/unpublish(.:format) {:controller=>"manage/publish", :action=>"destroy"}
Which is the routes I want, just not mapping to the correct controller. I've tried everything I can think of try and allow for the controller not to carry the namespace, but I'm stumped.
I know that I could do the following:
get 'manage/features/:feature_id/publish' => "publish#create", :as => "manage_project_publish"
which produces:
manage_project_publish GET /manage/projects/:project_id/publish(.:format) {:controller=>"publish", :action=>"create"}
but ideally, I'd prefer to use the nested declaration (for readability) - if it's even possible; which I'm starting to think it isn't.
resource takes an optional hash where you can specify the controller so
resource :projects do
would be written as
resource :projects, :controller=>:publish do
Use scope rather than namespace when you want a scoped route but not a controller within a module of the same name.
If I understand you correct, you want this:
scope :manage do
resources :projects, :only => [] do
get 'publish' => 'publish#create'
get 'unpublish' => 'publish#destroy'
end
end
to poduce these routes:
project_publish GET /projects/:project_id/publish(.:format) {:action=>"create", :controller=>"publish"}
project_unpublish GET /projects/:project_id/unpublish(.:format) {:action=>"destroy", :controller=>"publish"}
Am I understanding your need correctly? If so, this is what Ryan is explaining.
I think what you want is this:
namespace :manage, module: nil do
resources :projects do
get 'publish' => 'publish#create'
get 'unpublish' => 'publish#destroy'
end
end
This does create the named routes as you wish(manage_projects...) but still call the controller ::Publish
It's a bit late but for anyone still struggling with this, you can add a leading slash to the controller name to pull it out of any existing namespace.
concern :lockable do
resource :locks, only: [] do
post "lock" => "/locks#create"
post "unlock" => "/locks#destroy"
end
end
Now if you include that concern anywhere (either namespaced or not) you will always hit the LocksController.
I have the following in my routes.rb
map.resources :novels do |novel|
novel.resources :chapters
end
With the above defined route, I can access the chapters by using xxxxx.com/novels/:id/chapters/:id.
But this is not what I want, the Chapter model has another field called number (which corresponds to chapter number). I want to access each chapter through an URL which is something like
xxxx.com/novels/:novel_id/chapters/:chapter_number. How can I accomplish this without explicitly defining a named route?
Right now I'm doing this by using the following named route defined ABOVE map.resources :novels
map.chapter_no 'novels/:novel_id/chapters/:chapter_no', :controller => 'chapters', :action => 'show'
Thanks.
:id can be almost anything you want. So, leave the routing config untouched and change your action from
class ChaptersControllers
def show
#chapter = Chapter.find(params[:id])
end
end
to (assuming the field you want to search for is called :chapter_no)
class ChaptersControllers
def show
#chapter = Chapter.find_by_chapter_no!(params[:id])
end
end
Also note:
I'm using the bang! finder version (find_by_chapter_no! instead of find_by_chapter_no) to simulate the default find behavior
The field you are searching should have a database index for better performances
