rails routing aliases - ruby-on-rails

I have a model called Spaces which has different types of places... such as Bars, Restaurants, etc. It has the same columns, same, model, controller, etc. no fancy STI, I just have one field called Space_type which I would like to determine an aliased route.
Instead of domain.com/spaces/12345 it would be /bars/12345 or /clubs/12345
Currently I have:
resources :spaces do
collection do
get :update_availables
get :update_search
get :autocomplete
end
member do
post :publish
post :scrape
end
resources :photos do
collection do
put :sort
end
end
resources :reviews
end
Also, Is there a way I can do this so that anytime I use the space_url it can figure out which one to use?

The routes are not a way to interact with your model directly. So, as long as you write a standard route, you can make things work. For instance, to make /bars/12345 and /clubs/12345 for your spaces_controller (or whatever the name of the controller is) , you can create routes like :
scope :path => '/bars', :controller => :spaces do
get '/:id' => :show_bars, :as => 'bar'
end
scope :path => '/clubs', :controller => :spaces do
get '/:id' => :show_clubs, :as => 'clubs'
end

# routes.rb
match "/:space_type/:id", :to => "spaces#show", :as => :space_type
# linking
link_to "My space", space_type_path(#space.space_type, #space.id)
which will generate this urls: /bars/123, /clubs/1 ... any space_type you have
And it looks like STI wold do this job little cleaner ;)
UPD
Also you can add constraints to prevent some collisions:
match "/:space_type/:id", :to => "spaces#show", :as => :space_type, :constraints => { :space_type => /bars|clubs|hotels/ }
And yes - it is good idea to put this rout in the bottom of all other routes
You can also wrap it as a helper (and rewrite your default space_url):
module SpacesHelper
def mod_space_url(space, *attrs)
# I don't know if you need to pluralize your space_type: space.space_type.pluralize
space_type_url(space.space_type, space.id, attrs)
end
end

how to make dynamic nested routes on rails?

I'll explain when open www.domain.com/:id should be check the :id is a page then use
get ':id' => 'pages#show'
else if :id is a Category use
get ':category' => 'categories#show'
sorry for my english
get ':page' => 'pages#show'
resources :categories, :path => '/' do
resources :posts, :path => '/'
end
constraints for routes is way to go, but I would suggest a bit different solution for your problem.
Consider creating custom Constraint objects, which will query the database in order to check if Post or Category exists:
app/lib/post_constraint.rb
class PostConstraint
def matches?(request)
Post.exists?(request[:id])
end
end
app/lib/category_constraint.rb
class CategoryConstraint
def matches?(request)
Category.exists?(request[:id])
end
end
In your app/config/routes.rb
get ":id" => "posts#show", constraints: PostConstraint.new
get ":id" => "categories#show", constraints: CategoryConstraint.new
You have to be aware of the fact, that id is very poor candidate for such comparison, because the Post is checked in first place, and if there is record matching, the "posts#show" will be accessed, and CategoryConstraint wot be even bothered.
For more, check the documentation.
You should consider adding a slug for both models to easier serve exactly what user expects to see. For this purpose, try gem friendly_id.
Hope that helps! Good luck!
why dont you write something like this:
routes.rb
get '/:category_id/:post_id', to: 'categories#post'
and in your categories_controller.rb
def post
#params[:category_id] and params[:post_id] will contain the params from the url
end
Couple of solutions
If your post id and category id follow a pattern you can add constraints to your routes
1)
get ':post_id' => 'posts#show', :constraints => { :id => /[A-Z]\d{5}/}
get ':category_id' => 'categories#show', :constraints => { :id => /[1-9]\d{5}/ }
2)
Add a custom method where both post_id/category_id routes point, in that check if the id is a post id or category id and based on that render the page

Can't figure out how Rails route helper should look

I am working on an assignment which includes adding a feature to Typo.
rake routes shows:
admin_content /admin/content {:controller=>"admin/content", :action=>"index"}
/admin/content(/:action(/:id)) {:action=>nil, :id=>nil, :controller=>"admin/content"}
I need to create a route helper which matches the following RESTful route: /admin/content/edit/:id and an example of url is /admin/content/edit/1
But I can't figure out how to do it. I tried something like admin_content_path(edit,some_article) but it didn't work. (some_article is just an article object)
In routes.rb file:
# some other code
# Admin/XController
%w{advanced cache categories comments content profiles feedback general pages
resources sidebar textfilters themes trackbacks users settings tags redirects seo post_types }.each do |i|
match "/admin/#{i}", :to => "admin/#{i}#index", :format => false
match "/admin/#{i}(/:action(/:id))", :to => "admin/#{i}", :action => nil, :id => nil, :format => false
end
#some other code
Thanks a lot for your help!
If you are using RESTful routes, why not use the Rails default routes?
So your routes.rb would look like
namespace :admin do
resources :content
resources :advanced
resources :categories
resources :comments
...
<etc>
end
This does assume all your controllers are in the folder admin (but from your comment this seems to be the case.
If you do that, you can just use the standard route-helper: edit_admin_content_path.
If you want to do it manually, you should try adding a name to your route. E.g. as follows:
match "/admin/#{i}/:action(/:id)" => "admin/#{i}", :as => "admin_#{i}_with_action"
and then you should do something like
admin_content_with_action(:action => 'edit', :id => whatevvvva)
As a side-note: I really do not like the meta-programming in your config/routes.rb, if for whatever you really find that the default resources are not a right fit, I would advise to use methods instead (as explained here)
So for example in your config/routes.rb you would write:
def add_my_resource(resource_name)
match "/#{resource_name}", :to => "#{resource_name}#index", :format => false
match "/#{resource_name}(/:action(/:id))", :to => "#{resource_name}", :as => 'admin_#{resource_name}_with_action", :action => nil, :id => nil, :format => false
end
namespace :admin do
add_my_resource :content
add_my_resource :advanced
add_my_resource :categories
...
end
which imho is much more readable.
But my advice, unless you really-really need to avoid it, would be to use the standard resources since you do not seem to add anything special.
HTH.

Mapping action in rails

In my routs.rb I have the following lines
CyberTrackRails3::Application.routes.draw do
scope "(:locale)", :locale => /en|de|nl/ do
resources :transfusion do
get 'detail', :on => :collection
end
end
end
Next line
url_for( :controller => :transfusion, :action => :detail,
:id => bloodselection[:id]
gets mapped to /nl/transfusion/detail?id=162106
How do I map it to /nl/transfusion/162106 so that controller understands it as id being 162106?
That happens because you are setting the detail action on collection, to follow your url structure, it needs to be defined on member.
ie,
CyberTrackRails3::Application.routes.draw do
scope "(:locale)", :locale => /en|de|nl/ do
resources :transfusion do
get 'detail', :on => :member
end
end
end
The Rails routing engine pluralizes collections by default, so if you want the defaults to work out of the box, you should use the plural, transfusions
Then instead of url_for, you could use transfusion_path to get /nl/transfusions/12345
If you insist on using the singular form in the URL, you can override the path segment as
resources :transfusions, path: "transfusion" do …
which would let you get /nl/transfusion/12345 instead.

Rails 3: making a catch-all route easier to read and amend

I'm trying to write a catch-all route in Rails 3, but I want to reserve some terms in it. I'm specifically following the example put forth in this post, in the answer by David Burrows: Dynamic routes with Rails 3
The syntax I am using is the following:
match '*path' => 'router#routing', :constraints => lambda{|req| (req.env["REQUEST_PATH"] =~ /(users|my-stuff)/).nil? }
Now, that syntax works just fine - if a user visits a page with "user" or "my-stuff" in the path, it falls through the catch-all and goes to a specific place. If the user goes to any other URL, it goes to my routing logic.
My question is more about readability - is there a way I can match the route against something other than a regex? Is there a way to provide an array of terms to match against? Also, is there a way to match specific segments of the route, as opposed to the entire thing?
Obviously Rails has built-in routing, but this project has a requirement that for certain routes, the controller not be present in the URL. Hence, the catch-all.
Thanks for any help
Here's the updated routes file per the answer below:
class RouteConstraint
RESERVED_ROUTES = ['users', 'my-stuff']
def matches?(request)
!RESERVED_ROUTES.map {|r| request.path.include?(r)}.empty?
end
end
App::Application.routes.draw do
resources :categories
resources :sites
match '*path' => 'router#routing', :constraints => RouteConstraint.new
devise_for :users, :path_names =>{ :sign_in => 'login', :sign_out => 'logout', :registration => 'register' }
root :to => "router#routing"
end
You can use a class to specify the constraints if you want something cleaner once you have multiple routes to try:
class MyConstraint
BYPASSED_ROUTES = ['users', 'my-stuff']
def matches?(request)
BYPASSED_ROUTES.map {|r| request.path.include?(r)} .empty?
end
end
TwitterClone::Application.routes.draw do
match "*path" => "router#routing", :constraints => MyConstraint.new
end
This example is adapted from the rails routing guide.
It's taking a lambda; you can use whatever criteria you want.

Rails 3 routing - what's best practice?

I'm trying out Rails, and I've stumbled across an issue with my routing.
I have a controller named "Account" (singular), which should handle various settings for the currently logged in user.
class AccountController < ApplicationController
def index
end
def settings
end
def email_settings
end
end
How would I set-up the routes for this in a proper manner? At the moment I have:
match 'account(/:action)', :to => 'account', :as => 'account'
This however does not automagically produce methods like account_settings_path but only account_path
Is there any better practice of doing this? Remember the Account controller doesn't represent a controller for an ActiveModel.
If this is in fact the best practice, how would I generate links in my views for the actions? url_to :controller => :account, :action => :email_settings ?
Thanks!
To get named URLs to use in your views, you need to specify each route to be named in routes.rb.
match 'account', :to => 'account#index'
match 'account/settings', :to => 'account#settings'
match 'account/email_settings', :to => 'account#email_settings'
Or
scope :account, :path => 'account', :name_prefix => :account do
match '', :to => :index, :as => :index
match 'settings', :to => :settings
match 'email_settings', :to => :email_settings
end
Either works the same, it's just a matter of choice. But I do think the first method is the cleanest even if it isn't as DRY.
You could also define it as a collection on the resource:
resources :login do
collection { get :reminder, :test }
end
Of course, this also defines the default CRUD actions as well. I'm currently only using two of those for my not-an-actual-model controller, but I don't think/expect there will be any problem with the extra routes.
