ruby on rails - Is there a way to set the controller action for resources defined with only: or except:? -

i have nested nested resources:

resources :assessments     member         'result'     end     resources :respondents, only: [:new, :create]       collection         post "invite", to: :invite_all         "invite", to: :new_invite       end     end   end 

for line resources :respondents, only: [:new, :create] possible set action new , crate actions? can use to: set action single resource. i'd avoid writing match statements if can , keep things resourceful.

what motivates me ask i'd able specify action nested resource rather have route child resource's action. example:

if define

resources :assessments     resources :respondents end 

the path /assessments/:id/respondents/new route respondents#new. problem forces me add logic new action determine if route contains assessment id or not , render correct view. i'd able send nested resource different action. there "rails way" this?

why not not nest resources this:

resources :assessments   member     'result'   end end  resources :respondents, only: [:new, :create]   collection     post "invite", to: :invite_all     "invite", to: :new_invite   end end 

or keep nesting other actions (e.g. index) define new , create actions separately.

resources :assessments   member     'result'   end   resources :respondents end  resources :respondents, only: [:new], path_names: { new: 'make' }   collection     post :generate     post "invite", to: :invite_all     "invite", to: :new_invite   end end 

this create these routes:

         result_assessment    /assessments/:id/result(.:format)                          assessments#result     assessment_respondents    /assessments/:assessment_id/respondents(.:format)          respondents#index                            post   /assessments/:assessment_id/respondents(.:format)          respondents#create  new_assessment_respondent    /assessments/:assessment_id/respondents/new(.:format)      respondents#new edit_assessment_respondent    /assessments/:assessment_id/respondents/:id/edit(.:format) respondents#edit      assessment_respondent    /assessments/:assessment_id/respondents/:id(.:format)      respondents#show                            patch  /assessments/:assessment_id/respondents/:id(.:format)      respondents#update                            put    /assessments/:assessment_id/respondents/:id(.:format)      respondents#update                            delete /assessments/:assessment_id/respondents/:id(.:format)      respondents#destroy                assessments    /assessments(.:format)                                     assessments#index                            post   /assessments(.:format)                                     assessments#create             new_assessment    /assessments/new(.:format)                                 assessments#new            edit_assessment    /assessments/:id/edit(.:format)                            assessments#edit                 assessment    /assessments/:id(.:format)                                 assessments#show                            patch  /assessments/:id(.:format)                                 assessments#update                            put    /assessments/:id(.:format)                                 assessments#update                            delete /assessments/:id(.:format)                                 assessments#destroy       generate_respondents post   /respondents/generate(.:format)                            respondents#generate         invite_respondents post   /respondents/invite(.:format)                              respondents#invite_all                               /respondents/invite(.:format)                              respondents#new_invite             new_respondent    /respondents/make(.:format)                                respondents#new 

this way new , create outside of of nested assessments.

i created these routes real quick locally , generated when running rake routes.
