I'm in trouble with routes in Rails. I've been trying to get a path like: home/blog/title-article but the closes I get is: home/blog/posts/title-article
I've tried with namespace, scope and one by one with get 'blog' => 'posts#blablabla', but I get errors like UrlGenerationError or NameError every time I change the paths. I've read the official guide and some answers in this forum, but I'm getting more confused hehe
In my last try I generated a controller Blog and a scaffold Post. The output of rake routes is: http://i.stack.imgur.com/gdfPc.png
routes.rb
Rails.application.routes.draw do
scope :blog do
resources :posts
end
get 'blog' => 'blog#index'
root 'pages#index'
...
Thank you!
Now my routes are like: http://i.stack.imgur.com/cKsFG.png
Thank you!
Not sure its what you expect but try:
resources :posts, path: 'blog'
Feels weird though.
Btw, I guess you have the errors due to url helpers.
use rake routes to check the existing routes and the related url helpers.

I'm currently using friendly_id and I'm trying to get route to not include the resource name.
Normally, the URL is www.website.com/projects/25.
With friendly_id it's www.website.com/projects/fun-project. This is what I currently have.
And I'd finally like it to be www.website.com/fun-project.
I found this question about this but the solution wasn't working for me for one case.
//routes.rb
root 'static#index'
...
resources :projects, path: ''
When doing resources :projects, path: '', the projects#show works correctly, but I cannot use projects#index as I was before.
In my navigation, the projects_path that used to link to www.website.com/projects now just links to www.website.com.
Do I need to do something else for this case?
Thanks.
You can use simply get for this purpose in the following way:
get '/:project_id' => 'projects#show'
What I understand so far, you want the following URL to your projects resources.
www.website.com/fun-project
here 'fun-project' is the friendly id of your project.
In order to achieve this you can add the following line to your route:
get '/:id' => 'projects#show'
And should work!
My site used to have a mobile view here:
https://www.example.com/m/home
We have deprecated the mobile views and now I need a simple way to trim the /m/ off the URL so that the request proceeds to the correct page.
Example:
https://www.example.com/m/about => https://www.example.com/about
https://www.example.com/m/user/:id => https://www.example.com/user/:id
I'm hoping to solve this in the Rails routing without having to introduce a new controller action or meddle with nginx. I have 100+ routes. Thanks in advance.
Rails version: 4.2
There is a redirection module (also documented in the guide).
Something like :
get '/m/about', to: redirect('/about')
get '/m/user/:id', to: redirect('/user/%{id}')
Which you can combine with route globbing for a generic solution :
get '/m/*path', to: redirect('/%{path}')
How about just refactor your routes a bit:
Eg: Previous routes.rb
resources :users
# ...
Now, it becomes:
['m', ''].each do |sc|
scope sc do
resources :users
# ...
end
end
I'm new to Rails, and I'm setting up models/controllers for Course and some other models.
When I visit the /courses/show URL in my browser I get the following error:
Couldn't find Course with 'id'=
Screenshot here.
Here's the relevant line from my rake routes and routes.rb:
rake routes
courses_show GET /courses/show(.:format) courses#show
config/routes.rb
get 'courses/show'
You have specified the four routes without any :id parameter, I don't know why you would expect them to have an :id parameter.
I'd recommend that you read the Rails guide on routing and also read the comments in the generated config/routes.rb, in that file you'll see comments like this:
# Example of regular route:
# get 'products/:id' => 'catalog#view'
So, extrapolating that to your example you might end up with:
get 'courses/:id' => 'courses#show'
The example that follows that one shows how to add a named route helper using the :as option:
get 'courses/:id' => 'courses#show', as: :courses_show
Something you'll also see when you read the guide or the comments is that you can use the resources helper to create standard restful routes.
I am about to migrate my rails 3 application to rails 4.
There are some additional routes on my ressources that make some problems.
I get an error message for this lines in my route file:
resources :teams do
...
get 'apply' => 'teams#apply_membership', as: :apply_membership
post 'apply' => 'teams#apply_membership_save', as: :apply_membership
...
This is the generated error message
You may have defined two routes with the same name using the `:as` option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with `resources` as explained here:
http://guides.rubyonrails.org/routing.html#restricting-the-routes-created
In rails3 it was possible to define a get and a post route using the same alias and routing them to different controler methods.
Can I do this in rails4, too?
And if yes, how does it have to look like in my route file?
You can not take two route name with same name. but you have done it. so please change,
get 'apply' => 'teams#apply_membership', as: :apply_membership
post 'apply' => 'teams#apply_membership_save', as: :update_membership
Take a look here for rails routings. http://guides.rubyonrails.org/routing.html
I'm trying to use the path from the following route, here is what it's like in rake routes
chapter GET /chapters/:id(.:format) {:action=>"show", :controller=>"chapters"}
chapter_path creates a link to /chapters/x which is correct but I get the routing error when trying to access it.
No route matches {:controller=>"chapters"}`
this is my routes (I am using shallow routing to create a books_chapters and book_chapters_new paths.
resources :books do
resources :chapters, :shallow => true
end
when I test the route with rake routes, I get books_chapters, books_chapters_new, chapters and books, so I don't know what's wrong.
when i remove :shallow => true, i can access /books/1/chapters/6 but I just want it to be /chapters/6
this is what my terminal looks like
so /chapters/id and /chapters/id/edit should be working fine.
I've restarted the server with touch tmp/restart.txt and ran rails s to see if the routes worked there too and rake routes is giving me acceptable routes, but they don't work for me.
Are you supplying the parameter for the path helper, something like
chapter_path(#chapter)
I couldn't figure out how to get :shallow routes to work, and there isn't an example on how to use :shallow in the rails guide so, instead I have to just use nested routes like so
resources :books do
resources :chapters
end
now this means the something like chapters_url or chapters_path won't work.
So I have to do something like this everywhere
book_chapter_url(#chapter.book, #chapter)
or
edit_book_chapter_path(#chapter.book, #chapter)
It works but there's a bit of code smell because I use #chapter twice and the whole url should be able to resolve just through the chapter id instead.
