Including attributes in custom Rails routes -

i hope title not misleading, don't know better title problem i'm working on:

i have doctor belongs location , specialty. i'd route show action of doc controller this:

/dentist/berlin/7

i defined routes this:

get ':specialty/:location/:id', to: 'docs#show' 

and in views create following url link show action of doc controller:

<%= link_to doc.name, "#{doc.specialty.name}/#{doc.location.name}/#{doc.id}" %> 

is solution problem? if not, there cleaner way construct urls possibly using resources? heck name problem?

thank your in advance.

for references, should have @ this page (especially the end of section 2.6)

if single route, it's okay did. if want have more 1 route (like /dentist/berlin/7, /dentist/berlin/7/make_appointment, etc.) might want structure bit more routes take advantage of rails resources.

for example, instead of

get ':specialty/:location/:id', to: 'doctors#show' ':specialty/:location/:id/appointment', to: 'doctors#new_appointment' post ':specialty/:location/:id/appointment', to: 'doctors#post_appointment' 

you have (the code equivalent, see explanation below)

resources :doctors, path: '/:specialty/:location', only: [:show]   member     'new_appointment'      post 'create_appointment'   end end 

explanation

• resources generate restful routes (index, show, edit, new, create, destroy) specified controller (doctors_controller assume)
• the 'only' means don't want add restful routes, ones specified

• then want add member actions, ie. actions can executed on particular item of collection. can chose different syntaxes

  resources :doctors   member      # here have prefix /:id action applies particular item   end end # or resources :doctors   'new_appointement', on: :member end 

• by default, controller action same path name give, can override it

  member   'appointment', action: 'new_appointment'   post 'appointment', action: 'post_appointment' end 

rails has wonderful helpers when comes routing !
