I have a problem with routing in my app, but i do not understand why. I hope someone can explain me why this is so.
thank you very much for help.
<%= link_to 'Show', restaurant_path(restaurant), :id => 'button_show_restaurant', :class => 'btn btn-success' %>
<%= button_to 'Show', restaurant_path(restaurant), :id => 'button_show_restaurant', :class => 'btn btn-success' %>
The link_to code routes correctly to the needed restaurant, but the button_to produces the following:
No route matches [POST] "/de/restaurants/526fe01e65617271ea000000"

By default, button_to does a post while link_to does a get. So you want this
<%= button_to 'Show', restaurant_path(restaurant), :id => 'button_show_restaurant', :class => 'btn btn-success', :method => :get %>
