Index View/Path not Listed in Rake Routes

When you run rake routes, it lists the routes or paths of the following actions/views:

index
new
create
show
edit
update (PUT request)
update (PATCH request)
destroy

But in some cases, you may not be able to find the index route. This is a typing mistake. Go to your routes.rb file and there will me something like this:

resource :model

OR

resource :models

You need to change you this line to make it a plural resource so that the rake could list index route. For this, use this line instead:

resources :models
