Rails Routes Wrong Prefix - ruby-on-rails

I'm getting a strange error when renaming the resourcce "like" to "love"
In routes.rb I've changed:
resources :likes
resources :recipes do
member do
get :likes
end
end
to
resources :loves
resources :recipes do
member do
get :loves
end
end
and rake:routes says
loves GET /loves(.:format) loves#index
POST /loves(.:format) loves#create
new_lofe GET /loves/new(.:format) loves#new
edit_lofe GET /loves/:id/edit(.:format) loves#edit
lofe GET /loves/:id(.:format) loves#show
PATCH /loves/:id(.:format) loves#update
PUT /loves/:id(.:format) loves#update
DELETE /loves/:id(.:format) loves#destroy
loves_recipe GET /recipes/:id/loves(.:format) recipes#loves
recipes GET /recipes(.:format) recipes#index
POST /recipes(.:format) recipes#create
new_recipe GET /recipes/new(.:format) recipes#new
edit_recipe GET /recipes/:id/edit(.:format) recipes#edit
recipe GET /recipes/:id(.:format) recipes#show
PATCH /recipes/:id(.:format) recipes#update
PUT /recipes/:id(.:format) recipes#update
DELETE /recipes/:id(.:format) recipes#destroy
and ofcourse i get an error
uninitialized constant User::Lofe
but where comes the prefix "Lofe"? looks a bit strange for me

This is due to the active support pluralization features in rails.
To solve your issue:
in config/initializers/inflections.rb add the following:
ActiveSupport::Inflector.inflections do |inflect|
inflect.uncountable %w(Loves)
end
After running $ rake:routes I get:
Prefix Verb URI Pattern Controller#Action
loves_index GET /loves(.:format) loves#index
POST /loves(.:format) loves#create
new_loves GET /loves/new(.:format) loves#new
edit_loves GET /loves/:id/edit(.:format) loves#edit
loves GET /loves/:id(.:format) loves#show
PATCH /loves/:id(.:format) loves#update
PUT /loves/:id(.:format) loves#update
DELETE /loves/:id(.:format) loves#destroy

Rails: routes generated by hand have different prefix from those created with resources

I want to create rails routes by hand rather than using the automatic resource :tasks (it's just an exercise, I'll go back to the using resources :tasks once I understand this).
I /think/ that I have the right syntax, but the prefixes (path_helpers) generated when I write the routes by hand are wrong. Why, and what am I not doing properly?
Here is my code:
Rails.application.routes.draw do
root to: 'tasks#index'
get 'tasks', to: 'tasks#index'
get 'tasks/:id', to: 'tasks#show'
get 'tasks/new', to: 'tasks#new'
post 'tasks', to: 'tasks#create'
get 'tasks/:id/edit', to: 'tasks#edit'
patch 'tasks/:id', to: 'tasks#update'
delete 'tasks/:id', to: 'tasks#destroy'
end
Here are the routes & prefixes it creates when I call rails routes in my terminal:
Prefix Verb URI Pattern Controller#Action
root GET / tasks#index
tasks GET /tasks(.:format) tasks#index
GET /tasks/:id(.:format) tasks#show
tasks_new GET /tasks/new(.:format) tasks#new
POST /tasks(.:format) tasks#create
GET /tasks/:id/edit(.:format) tasks#edit
PATCH /tasks/:id(.:format) tasks#update
DELETE /tasks/:id(.:format) tasks#destroy
Here is what I get when I use resource :tasks
Prefix Verb URI Pattern Controller#Action
tasks GET /tasks(.:format) tasks#index
POST /tasks(.:format) tasks#create
new_task GET /tasks/new(.:format) tasks#new
edit_task GET /tasks/:id/edit(.:format) tasks#edit
task GET /tasks/:id(.:format) tasks#show
PATCH /tasks/:id(.:format) tasks#update
PUT /tasks/:id(.:format) tasks#update
DELETE /tasks/:id(.:format) tasks#destroy
EDIT:
To answer a few of the answers: I know that I can use 'as' to name the prefixes, but I think that I shouldn't have to in this case.
From what I understand, 'as' is only used in case you want to change the standard prefix to a personalized one, or if you think your routes might change in the future and you don't want to risk to mess with with your helpers. I should still get correct prefixes without using 'as'.
Here though, the prefix tasks_new with the get method is both linked to the tasks#new and tasks#edit methods, which I don't think is right.
Rails will let you name the routes. For example:
get 'tasks/new', to: 'tasks#new', as: :new_task
Use as for naming the route.
Write the code as following:
Rails.application.routes.draw do
root 'tasks#index'
get 'tasks' => 'tasks#index', as: 'task_list'
get 'tasks/:id' => 'tasks#show', as: 'display_task'
get 'tasks/new' => 'tasks#new', as: 'task_new'
post 'tasks' => 'tasks#create', as: 'task_create
get 'tasks/:id/edit' => 'tasks#edit', as: 'task_edit'
patch 'tasks/:id', to: 'tasks#update'
delete 'tasks/:id', to: 'tasks#destroy'
end

I don't understand this error and how to resolve it.
I already read all posts about this error but can't find the solution..
Finally the solution was to with draw theses lines from routes.rb :
if defined?(DashboardManifest)
namespace :admin do
DashboardManifest::DASHBOARDS.each do |dashboard_resource|
resources dashboard_resource
end
root controller: DashboardManifest::ROOT_DASHBOARD, action: :index
end
end

Restful url not picking up id

I am having troubles with routes. I have defined routes like this:
resource :demo
resource :subjects
resource :pages
resource :sections
when i do
rake routes
it doesn't show right urls. it shows something like
Prefix Verb URI Pattern Controller#Action
root GET / demo#index
demo POST /demo(.:format) demos#create
new_demo GET /demo/new(.:format) demos#new
edit_demo GET /demo/edit(.:format) demos#edit
GET /demo(.:format) demos#show
PATCH /demo(.:format) demos#update
PUT /demo(.:format) demos#update
DELETE /demo(.:format) demos#destroy
subjects POST /subjects(.:format) subjects#create
new_subjects GET /subjects/new(.:format) subjects#new
edit_subjects GET /subjects/edit(.:format) subjects#edit
GET /subjects(.:format) subjects#show
PATCH /subjects(.:format) subjects#update
PUT /subjects(.:format) subjects#update
DELETE /subjects(.:format) subjects#destroy
pages POST /pages(.:format) pages#create
new_pages GET /pages/new(.:format) pages#new
edit_pages GET /pages/edit(.:format) pages#edit
GET /pages(.:format) pages#show
PATCH /pages(.:format) pages#update
PUT /pages(.:format) pages#update
DELETE /pages(.:format) pages#destroy
sections POST /sections(.:format) sections#create
new_sections GET /sections/new(.:format) sections#new
edit_sections GET /sections/edit(.:format) sections#edit
GET /sections(.:format) sections#show
PATCH /sections(.:format) sections#update
PUT /sections(.:format) sections#update
DELETE /sections(.:format) sections#destroy
GET /:controller(/:action(/:id(.:format))) :controller#:action
none of the urls has :id in them. what i might be doing wrong? It still sends id to controller but i am having hard time calling index and show methods as both of them are mapped to -----#show
This is because you are using singular resource, e.g. resource :foo. When you use singular resource, you don't get the :id. In order to get the :id in the parameter, you should change the resources declarations to plural resources:
resources :demoes
resources :subjects
resources :pages
resources :sections

How to re-name routes?

I have nested routes on my site for Sections and Pages.
resources :sections do
resources :pages
end
This is a sample URL:
sitename.com/sections/5/pages/22
I don't like the name 'sections', and would prefer 'chapters'.
sitename.com/chapters/5/pages/22
I assume re-naming the model would be to complicated, so how can I just re-name the route easily?
Pass your desired URL segment name as the value to the path argument:
resources :sections, :path => :chapters do
resources :pages
end
This results the the following routes:
section_pages GET /chapters/:section_id/pages(.:format) pages#index
POST /chapters/:section_id/pages(.:format) pages#create
new_section_page GET /chapters/:section_id/pages/new(.:format) pages#new
edit_section_page GET /chapters/:section_id/pages/:id/edit(.:format) pages#edit
section_page GET /chapters/:section_id/pages/:id(.:format) pages#show
PUT /chapters/:section_id/pages/:id(.:format) pages#update
DELETE /chapters/:section_id/pages/:id(.:format) pages#destroy
sections GET /chapters(.:format) sections#index
POST /chapters(.:format) sections#create
new_section GET /chapters/new(.:format) sections#new
edit_section GET /chapters/:id/edit(.:format) sections#edit
section GET /chapters/:id(.:format) sections#show
PUT /chapters/:id(.:format) sections#update
DELETE /chapters/:id(.:format) sections#destroy

Nested routes work but others don't

Struggling with routing in Rails!
This works: http://127.0.0.1:3000/locations/1/statistics but http://127.0.0.1:3000/locations/ does not work.
My routes look like this:
resources :locations do
resources :statistics
end
I can get only http://127.0.0.1:3000/locations/ working if I just do
resources locations
but then the nested routes don't work!
How can I get both working?
Many thanks.
EDIT rake routes:
location_statistics GET /locations/:location_id/statistics(.:format) statistics#index
POST /locations/:location_id/statistics(.:format) statistics#create
new_location_statistic GET /locations/:location_id/statistics/new(.:format) statistics#new
edit_location_statistic GET /locations/:location_id/statistics/:id/edit(.:format) statistics#edit
location_statistic GET /locations/:location_id/statistics/:id(.:format) statistics#show
PUT /locations/:location_id/statistics/:id(.:format) statistics#update
DELETE /locations/:location_id/statistics/:id(.:format) statistics#destroy
locations GET /locations(.:format) locations#index
POST /locations(.:format) locations#create
new_location GET /locations/new(.:format) locations#new
edit_location GET /locations/:id/edit(.:format) locations#edit
location GET /locations/:id(.:format) locations#show
PUT /locations/:id(.:format) locations#update
DELETE /locations/:id(.:format) locations#destroy
home_index GET /home/index(.:format) home#index
about /about(.:format) home#about
contact /contact(.:format) home#contact
root / home#index
EDIT 2 routes file
match '/about/' => 'home#about'
match '/contact/' => 'home#contact'
resources :locations do
resources :statistics
end
get "home/index"
EDIT 3
My actual error:
Routing Error
No route matches {:controller=>"statistics", :location_id=>nil}
when I go to http://127.0.0.1:3000/locations/
You should either use
=link_to "Locations", locations_path
or
# get sure #location is not nil
=link_to "Location Statistics", location_statistics_path(#location)
