Delete links stopped working data-method='delete' but goes to show page

问题:

I just noticed that all the various delete links in my application now just go to show pages. This application began as rails 2.3.8, it is now rails 3.2.17

Examples of the rails code:

Controllers,

def destroy   @group = Group.find(params[:id])   @group.destroy       respond_to do |format|     format.html { redirect_to(groups_url) }     format.xml  { head :ok }   end end  

And,

def destroy   @link = Link.find(params[:id])   @link.destroy   respond_to do |format|     format.html { redirect_to(links_url) }   end  end  

Which generates:

HTML,

<a rel="nofollow" data-method="delete" data-confirm="Sure?" href="/groups/35"> x </a> 

And,

<a rel="nofollow" data-method="delete" data-confirm="Sure?" href="/links/8"> x </a> 

I noticed that I had,

= javascript_include_tag "application" 

In my application layout template and I tried updating that to be,

= javascript_include_tag :defaults 

But it didn't help with this issue, still going to show page and not deleting and worse, doing this stopped all my other javascript from working! Such as leaving user on the search field automatically, the date-picker calendar, etc.

My application.js file has:

//= require jquery-1.7.2.min //= require jquery-ui-1.8.22.custom.min //= require default_on_first_input_field //= require row_shading //= require long_or_short_details //= require sortable_hook //= require date-picker //= require_self 

回答1:

The answer was that I needed to add just this line:

//= require jquery_ujs 

to my js manifest. This fixed it. My manifest now look like:

// Place your application-specific JavaScript functions and classes here // This file is automatically included by javascript_include_tag :defaults // //= require jquery-1.7.2.min //= require jquery-ui-1.8.22.custom.min //= require jquery_ujs //= require default_on_first_input_field //= require row_shading //= require long_or_short_details //= require sortable_hook //= require date-picker //= require_self
