"No route matches [POST]" when changing link_to to button_to

Question

I have this piece of code:

<%= link_to "New User", new_user_path, :class => "button"  %><br />

which works fine, but when I change it to,

<%= button_to "New User", new_user_path, :class => "button"  %><br />

I get this error

No route matches [POST] "/users/new"

Any help at all will be appreciated.

Answer 1

Jesus Rodriguez is right about POST and GET, but if you really need the button you can simply override the default method:

<%= button_to "New User", new_user_path, :class => "button", :method => :get  %>

Answer 2

The "link_to" is looking for a /users/new using GET.

The "button_to" is looking for a /users/new using POST

If you create the routes for a controller using:

resources :user

By default, /users/new is a GET and not POST so, the second line doesn't find any route.

If you are thinking to change that action to POST I think that you should forget about it.
