Nesting “get” request under a “get” with lambda in Rails routes












0














I have a get request which looks like this and works fine:



get ':slug', :to => "countries#show", 
:constraints => lambda { |r|
Country.find_by_slug(r.params[:slug]).present? }, as: :country


This makes urls like site.com/japan work fine.



Although the structure does not look nice, I am using it because there's a lot of legacy routes that are opening under root URL.



Anyway,



I need to nest additional resources under cities:



resources :places, only: :show


To enable urls such as: site.com/japan/tv-tower



I tried going with something like:



constraints lambda { |request| 
Country.find_by_slug(request.params[:slug]).present? } do
resources places, only: :show
end


But it doesn't work.

  • I think the issue is that the expression ':slug' only matches when there is no slash.

I'm assuming the result is not to have japan/places/tv-tower -- which is what you get if you don't set the path and the reason you aren't getting a valid route now.



I would forget about the :slug and just use resources for countries, even if it's only show, this will make sure you still have a valid route name and route for just the country with no place listed.



resources :countries, only: [:show], path: '', :constraints => proc { |req| Country.find_by_slug(req.params[:country_id].nil? ? req.params[:id] : req.params[:country_id])  } do
resources :places, path: ''
end


That will leave you with routes that look like:



       country_places GET    /:country_id(.:format)           places#index
POST /:country_id(.:format) places#create
new_country_place GET /:country_id/new(.:format) places#new
edit_country_place GET /:country_id/:id/edit(.:format) places#edit
country_place GET /:country_id/:id(.:format) places#show
PATCH /:country_id/:id(.:format) places#update
PUT /:country_id/:id(.:format) places#update
DELETE /:country_id/:id(.:format) places#destroy
country GET /:id(.:format) countries#show
