Question

Why would this work?

<%= link_to "New Item", new_site_care_path, {:class => "button_bottom"} %>

And this (the only change is from link_to to button_to)…

<%= button_to "New Item", :url => new_site_care_path, {:class => "button_bottom"} %>

…produces:

No route matches "/site_cares/new"

UPDATE – ROUTE INFO –
route file:

resources :site_cares, :except => :show

rake routes:

new_site_care GET /site_cares/new(.:format) {:action=>"new", :controller=>"site_cares"}

Answer 1

I think that button_to uses post by default, my ROR route skills are a bit rusty but I think the route you’ve shown uses GET.

There’s further info in this question – Button_to in Ruby on Rails bad route
