Renaming parameters in nested resources - ruby-on-rails-4

Question

In Rails 4.2.6, I am creating nested resources like this
routes.rb:
resources :analysis, param: :project_id do
resources :configuration
end
resources :decision, param: :project_id do
resources :configuration
end
It works fine when I am in the analysis or decision controller. However, when I am in the configuration controller, I receive the param :analysis_project_id or :decision_project_id. How can I change this so I still receive :project_id?
I don't want to customize my configuration controller to be aware that it is nested in different resources.

Answer 1

just this, you need not to send params over here, It will take automatically with corresponding to your action.
resources :analysis do
resources :configuration
end
if you need routes like these
analysis_configuration_index GET /analysis/:analysis_id/configuration(.:format) configuration#index
POST /analysis/:analysis_id/configuration(.:format) configuration#create
new_analysis_configuration GET /analysis/:analysis_id/configuration/new(.:format) configuration#new
edit_analysis_configuration GET /analysis/:analysis_id/configuration/:id/edit(.:format) configuration#edit
analysis_configuration GET /analysis/:analysis_id/configuration/:id(.:format) configuration#show
PATCH /analysis/:analysis_id/configuration/:id(.:format) configuration#update
PUT /analysis/:analysis_id/configuration/:id(.:format) configuration#update
DELETE /analysis/:analysis_id/configuration/:id(.:format) configuration#destroy
analysis_index GET /analysis(.:format) analysis#index
POST /analysis(.:format) analysis#create
new_analysis GET /analysis/new(.:format) analysis#new
edit_analysis GET /analysis/:id/edit(.:format) analysis#edit
analysis GET /analysis/:id(.:format) analysis#show
PATCH /analysis/:id(.:format) analysis#update
PUT /analysis/:id(.:format) analysis#update
DELETE /analysis/:id(.:format) analysis#destroy

To get the specific param in nested resources
resources :analysis, param: :project_id do
member do
resources :configurations
end
end
resources :decision, param: :project_id do
member do
resources :configurations
end
end
Expected routes
configurations GET /analysis/:project_id/configurations(.:format) configurations#index
POST /analysis/:project_id/configurations(.:format) configurations#create
new_configuration GET /analysis/:project_id/configurations/new(.:format) configurations#new
edit_configuration GET /analysis/:project_id/configurations/:id/edit(.:format) configurations#edit
