Since I used scaffolding to create my Deposit model,
resources :deposits
generates a bunch of routes. i want to be able to delete some of those routes for particular models. For example I do not want a "deposts/23/edit" route. I know I can do a redirect in the controller or do a
match "deposits/:id/edit", :to => "deposit#new"
which just shows the new deposit page but does not change the url on the browser.
is there a way to completely remove a certain action through declaring something in the rails routes.rb file. so that particular actions are just not accessible.
I reccomend looking over the Ruby on Rails Guide for Routing it discuses important core concepts and presents you with some good information on how routes are wired the way they are.
If you still wish to remove the edit route you will find a useful part of the guide here the code you need is listed below:
resources :deposits, :except => :edit
resources :deposits, :only => { :create, :new }
resources :deposits, :except => :edit

My app has a Company model and User models, I've been working on the path/url structure and have managed to get it working how I wish using nested resources as shown in the code below.
I've used FriendlyID to added company_names and usernames to the models which all works fine.
The path now look how I want they to look:www.mydomain.com/company_name/username
routes.rb
resources :companies, :path => '/', only: [:show] do
# constraints has been added for usernames that include a '.'
resources :users, :path => '/', only: [:show], :constraints => { :id => /.*/ }
end
PROBLEM: I still need the ability to add a new company record but it will no longer work. I understand this is due to changing the routes but I don't understand how to remedy this as it keeps viewing
www.mydomain.com/companies/new as an unknown user with the username 'new'.
I'd be grateful if anyone can point me in the right direction or give me a hard with this.
You have set only: [:show], which it means only show method is allowed.
To create a company, need to add :new and :create.
Something like this only: [:new, :create, :show]
Note:
Always after adding or changing smth in routes file, make sure to use rake routes, Rails 5 supports rails routes also.
You can see available routes!
I have a big feature called 'press releases'.
Client wants URL to say /updates rather than /press_releases.
Basic CRUD.
Is it possible to change the URL without renaming everything?
For example, when I say resources_path - is it possible to make it generate link /updates ?
Routes look like this:
resources :press_releases, except: :new do
collection do
post 'sort'
end
end
You can use a combination of options to do this.
The controller option allows you to specify a controller to use for the routes, and the as option allows you to rename the helpers.
So, something like this should work:
resources :updates, controller: 'press_releases', as: 'press_releases', except: :new do
collection do
post 'sort'
end
end
Sure,
resources :press_releases, :path => "/updates", except: :new do
collection do
post 'sort'
end
end
I am creating a website with a blog module. A blog post can either be a draft or published.
A published post can no longer be edited, and a draft cannot be viewed (only edit)
I currently have a resource defined as
resources :posts, :path => "blog" do
collection do
get 'drafts'
end
end
I can access the drafts list using blog/drafts, creating new ones posts using blog/new, and editing drafts through blog/:id/edit.
However, I'd like new drafts to be created using blog/drafts/new and edited using blog/drafts/:id
I need to define the new, create, edit and update routes to use this new scheme. The new and create routes seem quite simple. However I do not know how to handle the edit route in order to remove the action name part.
Also, while looking at the default routes definition, I found in actionpack-3.2.9/lib/action_dispatch/routing/mapper.rb the following :
member do
get :edit if parent_resource.actions.include?(:edit)
get :show if parent_resource.actions.include?(:show)
[...]
end
I do not understand how rails differentiates the :edit and the :show routes, and map the urls accordingly.
Thanks
You can use the following routes. Keep in mind that it requires different file hierarchy, rake routes should be your friend in this.
namespace :blog do
resources :drafts, :controller => :posts, only: [:new, :edit]
resources :posts, only: :show
end
I have a controller SubscriptionsController with only actions new and create. How would I redirect to new if say someone tries to visit GET /subscriptions which would normally trigger the index action?
config/routes.rb
resource :subscriptions, :only => [:new, :create]
Using rails3 you can do it from a route, something like:
match "/subscriptions", :to => redirect("/subscriptions/new")
Edit:
From the comments it was made clear you want to capture more than that, using a wild card you can make it more generic. You may need to combine this form with the previous to deal with the non-slash form (or try the below form without a slash, I havent tried that). Also make sure to put these "catch all" routes below your other ones since routes are matched from top to bottom.
match "/subscriptions/*other", :to => redirect("/subscriptions/new")
My homecontroller has:
def about()
end
And I have a rspec test that does GET 'about' and it fails saying that there is no route that matches.
doesn't this map all actions in the controller:
resources :home
or do I have to explicitly state each action in the home controller?
resources :home sets up the default RESTful routes - index, show, new, create, edit, update, and destroy. Any additional routes have to be specified. It looks like you're adding a simple collection route, so you'd specify it like this:
resources :home
collection do
get 'about'
end
end
This will give your the route '/home/about'. I assume this is Rails 3. If you're in Rails 2.x, do it like so:
map.resources :home, :collection => {:about => :get}
And from the command line, you can always see what routes you have available with this command:
rake routes
I hope this helps!
EDIT: If you want a default route, you can add this:
match ':controller(/:action(/:id))'
This is a default route that will match any generic requests.
FULL ARTICLE: Routing in Rails 3 is its own beast. There have been a lot of questions about it lately, so I've created a very detailed article with code samples to help others:
Routing in Ruby on Rails 3
I created a companion Rails 3 app that can be downloaded to play around with, as well:
https://github.com/kconrails/rails3_routing
If you have any questions, please hit up my site and ask. Thanks!
resources will give you the 7 CRUD methods for a controller, if you want additional actions, you need to do something like the following:
resources :homes do
collection do
match "about" => "homes#about", :as => "about"
end
end
Then you'll also have an additional about_homes_path/url helper available.
