I'm just starting with Devise and Rails3. I have the Authenetication down and working and understand the basics. As of now in my Home Controller that represents my Home/Front Page i have two links one that links to Register => sign_up and one that changes depending on login/logout => sign_in/sign_out. However i dont want to redirect my user to login page. Instead i want to display my login form on my front page. So i have seperated the devise/session/new template int to a view and a _form.html.erb partial. And now in my home view i render the login form as so: <% if user_signed_in? %> Welcome:

In a partial file of my application I have the following code snippet for displaying user navigation(through Devise):- <ul class="nav pull-right"> <% if user_signed_in? %> <li> <%= current_user.email do %> <i class=" icon-user icon-black"></i> <% end %> </li> <li> <%= link_to "Your Links", profiles_index_path do %> <i class=" icon-user icon-black"></i> <% end %> </li> <li> <%= link_to "Sign out", destroy_user_session_path, :method => 'delete' do %> <i class=" icon-user icon-black"></i> <% end %> </li> <% else %> <li> <%= link_to "Login", new_user_session_path do %> <i class=" icon-lock"></i> <

I'm using Rails 3.2.6 with strong parameters gem. So, I' have a controller with the typical update action: # PUT /api/resources/:id def update @resource.update_attributes! permited_params respond_with_json @resource, action: :show end Then, I have the permited_params method def permited_params params.permit(:attr1, :attr2, :attr3) end The problem is that :attr3 is a multidimensional array like this: [[1, 2], [2, 5, 7]] Following the documentation, I need to specify :attr3 as an array. But... params.permit(:attr1, :attr2, :attr3 => []) #inspecting permited_params: {"attr1"=>"blah", "attr2"=>

I had got a task to select search the students those name start with param value and city in the selected value.How can i set in ruby on rails? i did like this but this is not working controller def list studentcount=Student.count() puts studentcount @studentname = Student.where("name name1 AND city = :cityId1", {:name1 => params[:name], :cityId1 => params[:cityId]}) puts 'studentname' puts @studentname.inspect @students = Student.limit(params[:jtPageSize]).offset(params[:jtStartIndex]).order(params[:jtSorting]) @jtable = {'Result' => 'OK','Records' => @students.map(&:attributes),

I have "documents" (activerecords) with an attribute called deviations. The attribute has values like "Bin X" "Bin $" "Bin q" "Bin %" etc. I am trying to use tire/elasticsearch to search the attribute. I am using the whitespace analyzer to index the deviation attribute. Here is my code for creating the indexes: settings :analysis => { :filter => { :ngram_filter => { :type => "nGram", :min_gram => 2, :max_gram => 255 }, :deviation_filter => { :type => "word_delimiter", :type_table => ['$ => ALPHA'] } }, :analyzer => { :ngram_analyzer => { :type => "custom", :tokenizer => "standard", :filter =>

I'm trying to log requests for my REST API application. I'm using rails notifications for this , like here http://railscasts.com/episodes/249-notifications-in-rails-3 I can't understand how to solve one problem with rails notifications. my initializer code ActiveSupport::Notifications.subscribe "process_action.action_controller" do |name, start, finish, id, payload| p name p start p finish p id p payload end Controller respond section class PostsController < ApplicationController # GET /posts # GET /posts.json respond_to :json, :html .... end Controller create action def create @post = Post

I'm using rails 3.2.6 and I need to create a database VIEW. As usual I created a migration and I tried to achieve the goal using the execute method. Unfortunately the migration generates a table, not a view. Why? Many thanks in advance, Mauro UPDATE: I would like to have something as follows: class CreateMyView < ActiveRecord::Migration def self.up execute <<-SQL CREATE VIEW my_view AS SELECT ... SQL end def self.down execute <<-SQL DROP VIEW my_view SQL end end Unfortunately this migration creates a table... UPDATE: the previous code works! I was executing rake db:reset instead of rake db
