user_stories/show 

<%= link_to "Add new task",{:controller => ':tasks', :action => :new},:user_story_id: = >@user_story.id, remote: true %>

tasks/new.js.erb

$('#new_task_link').hide().after('<%= j render :partial => "form" %>');

Nest your tasks resources under your user_stories resources in config/routes.rb:

resources :user_stories do
  resources: tasks
end

Your link then becomes:

<%= link_to "Add new task", user_story_tasks_path(@user_story.id) %>

In the TasksController, you'll now have access to :user_story_id in the params.

A Rails Cast covers this. It's a bit outdated (map is no longer necessary in config/routes.rb), but the fundamental concept is still the same.
