Question

Very new to ruby on rails and trying to get my first ajax call working. It is making the ajax call, but it always calls the #index action and seems to ignore the URL parameter. Here’s the code:

class UserController < ApplicationController
def flag
    logger.debug "in flag user"
    respond_to do |format|
      format.js { render :layout=>false }
    end
  end
end

In my routes.db:

resources :users do
    member do
      post 'flag'
      get 'flag'
    end
  end

And then in my view I create the link like this:

<%= link_to "Flag User", :url => flag_user_path(user.id), :method => :get, :remote => true %>

the HTML source is:

<a href="/users?method=get&amp;url=%2Fusers%2F1%2Fflag" data-remote="true">Flag User</a>

rake routes produces this:

flag_user  POST   /users/:id/flag(.:format)   users#flag
           GET    /users/:id/flag(.:format)   users#flag

Whenever I click on the link, the user#index method always gets executed. How do I get the user#flag method to execute?

The issue was the :url symbol. I changed:

<%= link_to "Flag User", :url => flag_user_path(user.id), :method => :get, :remote => true %>

to:

<%= link_to "Flag User", flag_user_path(user.id), :method => :get, :remote => true %>

and everything works was expected. I was incorrectly using it like link_to_remote which requires the :url symbol. Thanks everyone for their input.
