Custom routes with id attribute

I'm confused as to how to sort out routes for my show action. At the moment if I select on a particular guidelines to 'show' it, the url says

/guidelines/1

where 1 is the guideline id

I'd like it to say

/title

(where this is the title of the guideline that is being shown). I'm confused how to manage this in my routes. At the moment my routes has

get 'guideline/:id', to: 'guidelines#show', as: :seeguideline

but this just shows guideline/1 as I mentioned so I realise I'm doing something wrong

My view links to this with

<%= link_to guideline.title, seeguideline_path(id: guideline.id) %>

show action in guidelines_controller.rb is

def show
    @guideline = Guideline.where(title: params[:title]).first
    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @guideline }

    end
  end

routes are

ActiveAdmin.routes(self)

  devise_for :admin_user, ActiveAdmin::Devise.config


  get "guidelines/topic"
  get "guidelines/topichospital"
  get "guidelines/topicspecialty"
  get "guidelines/favourite"


  devise_for :users

  devise_scope :user do
    get 'signup', to: 'devise/registrations#new', as: :register
    get 'login', to: 'devise/sessions#new', as: :login
    get 'logout', to: 'devise/sessions#destroy', as: :logout
    get 'edit', to: 'devise/registrations#edit', as: :edit
    put 'users' => 'devise/registrations#update', :as => 'user_registration'
    get 'about', to: 'about#about', as: :about
  end

  resources :guidelines
  get 'guidelines', to: 'guidelines#index', as: :guidelines
  get 'favourites', to: "favourites#show", as: :favourites
  get 'topics', to: 'guidelines#list', as: :topics
  get 'hospitals', to: 'guidelines#listhospital', as: :hospitals
  get 'specialties', to: 'guidelines#listspecialty', as: :specialties



  root :to => 'guidelines#index'
  get '/:id', to: 'profiles#show', as: :myprofile
  get '/:title', to: 'guidelines#show', as: :seeguideline

if you want to match urls like '/url', you need to place this at the bottom of your routes file so it takes the least priority (ie it doesnt match '/projects' if you have a projects controller). in theory this is done via

match '/:title' => 'guidelines#show', as: :seeguideline

then in your controller

def show
  @guideline = Guideline.where(title: params[:title]).first
end

then in your views, you can use

seeguideline_path(@guideline.title)

but you also have to take care of invalid characters in the title to be used in the url.
