Rails-link_to和button_to

Question

In my Rails 3.2.3 application I'm using Ajax and jQuery. There is a link on a page and I want to replace it with a button. The code below is working perfect

<%= link_to "More", {:controller => "home", :action => "test_method", :page=>@current_page }, :remote => true,:id => 'lnk_more' %>

But this one doesn't

<%= button_to "More", {:controller => "home", :action => "test_method", :page=>@current_page }, :remote => true,:id => 'lnk_more' %>

The result html for a link and for a button is here

#link
<a href="/home/test_method?page=1" data-remote="true" id="lnk_more" disabled="disabled">More </a>


#button
<form action="/home/test_method?page=1" class="button_to" data-remote="true" method="post"><div><input id="lnk_more" type="submit" value="More "><input name="authenticity_token" type="hidden" value="hFCuBR+88FYKEvNTZok+QRhxf6fHA+ucC6i2yc9hBEk="></div></form>

What have I done wrong?

Answer 1

<%= button_to "More", 
     { :controller => :home, :action=> :test_method, :page => @current_page}, 
     { :remote => true, :id => 'lnk_more' } 
 %>

will give an id to the input

<input id="lnk_more" type="submit" value="More">

Answer 2

You must change the method :method=>:get , since by default it is set to post . And your routes are probably not routing it correctly

<%= button_to "More", {:controller => "home", :action => "test_method", :page=>@current_page }, :method=>:get, :remote => true,:id => 'lnk_more' %>

According to the documentation the remote option should be part of options . See http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-button_to
