No Route Matches

I’m programming a web system for a rental of movies and put the resource
for rent a movie, but the routes don’t maches and the rails gives me
that message of error. My code and the error gived by rails are in
pictures. Thank you for the attention and for the help.

It is better to copy/paste information rather than linking to images.
That way we can insert comments inline in the text. Only post
information that is relevant to the problem of course.

Even more significantly you have not posted the contents of routes.rb
or shown us the output from
rake routes

Sorry Colin, I’ll try to explain in a better way. In my system I have a
variable called ‘movie’ and this ‘movie’ have a boolean attribute
‘rented’ that describes if this ‘movie’ was rented or not. I’ve created
a scaffold to this variable and int this scaffold I put a new link to
modify this attribute in this way:

Please remember to quote the previous message and insert your reply at
appropriate points.

You can have the root of your site routed with “root”

automatically):

get ‘sold’

resources :products do

resources :posts, concerns: :toggleable

No route matches {:action=>“rent”, :id=>1, :controller=>“movies”}

You have asked for action rent on the movies controller but you have
not provided a route for that.

I suggest you work right through a good tutorial such as
railstutorial.org (which is free to use online) which will show you
the basics of rails.

If you have a look at the Rails Guide on Routing then it will show you
how to do it, but best to work through the tutorial first.

Sorry Colin, I’ll try to explain in a better way. In my system I have a

The priority is based upon order of creation: first created ->

highest priority.

See how all your routes lay out with “rake routes”.

You can have the root of your site routed with “root”

root ‘welcome#index’

Example of regular route:

get ‘products/:id’ => ‘catalog#view’

Example of named route that can be invoked with purchase_url(id:

product.id)

get ‘products/:id/purchase’ => ‘catalog#purchase’, as: :purchase

Example resource route (maps HTTP verbs to controller actions

automatically):

resources :products

Example resource route with options:

resources :products do

member do

get ‘short’

post ‘toggle’

end

collection do

get ‘sold’

end

end

Example resource route with sub-resources:

resources :products do

resources :comments, :sales

resource :seller

end

Example resource route with more complex sub-resources:

resources :products do

resources :comments

resources :sales do

get ‘recent’, on: :collection

end

end

Example resource route with concerns:

concern :toggleable do

post ‘toggle’

end

resources :posts, concerns: :toggleable

resources :photos, concerns: :toggleable

Example resource route within a namespace:

namespace :admin do

# Directs /admin/products/* to Admin::ProductsController

# (app/controllers/admin/products_controller.rb)

resources :products

end

end
