Question

I have a rails app . I have created a sessionscontroller and want to redirect to users page ‘/users’ once the user signs in. But the redirect doesnt seem to be happening.

class SessionsController < ApplicationController

  def create
     user = User.find_or_create_by_fbid(params[:user][:fbid]) #...Success
     user.update_attributes(params[:user])  #....Sucess
     sign_in(user)  # ....This occurs successfully 
     redirect_to users_path # .... Redirect doesnt occur on the browser side 
  end

end

The sign_in method is defined inside the Application Controller

class ApplicationController < ActionController::Base

  def sign_in(user)
    session[:fbid] = user.fbid
    @current_user = user
  end

end

Server Logs below . The redirect actually seems to be happening on the server side . But I do not see any change on the client side. The browser doesnt change page.

The UsersController

class UsersController < ApplicationController

  def index

    @users = User.all

    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render :xml => @users }
    end
  end

  end

Original Ajax Post –

$.post("/sessions",{user:{name:profile.name, email:profile.email,fbid:profile.id}}); 

The redirect occurs successfully if I use a javascript redirect statement inside the $post() as a callback function .

$.post("/sessions",{user:{name:profile.name, email:profile.email,fbid:profile.id}},function( data ) {
          window.location="/users";
      }
    );

You need to handle the response’s redirection in an ajax query. Normally the browser handles, but it won’t with ajax.

From this SO question (edited slightly for your case)

var params = {user:{name:profile.name, email:profile.email,fbid:profile.id}};
$.ajax({
type: "POST",
url: "/sessions",
data: params,
dataType: "json",
success: function(data, textStatus) {
    if (data.redirect) {
        // data.redirect contains the string URL to redirect to
        window.location.href = data.redirect;
    }
    else {
        // data.form contains the HTML for the replacement form
        $("#login_form").replaceWith(data.form);
    }
}

});
