#BetterRate RoR wrapper of Raty plugin

Fork of RatyRate Stars Rating Gem

It focues on view part and reduces queries. Idea is to have functionality like

• order by
• imdb of user with eager load
• lots of eager load
• imdb rating of rateable object itself with eager loading

Setup

Gemfile

gem 'betterrate', :github => 'VarunBatraIT/BetterRate'

Terminal

rails g betterrate user
rake db:migrate

Include js files

//= require jquery.raty
//= require betterrate

Assuming that you have Movie model and User model

  #movie.rb
  betterrate_rateable "Action", "Story" # "Action and Story are two dimensions"

Note that dimensions can't have spaces since it creates functions dynamically, due to sorting, I can't handle it everywhere. Please make sure you do your homework :).

  #user.rb
  betterrate_rater

#View

Movie  : <%= rating_for @movie, "Action" %>
Story : <%= rating_for @movie, "Story" %>

#Other Helpers

Shows overall avg
<%= imdb_style_rating_for(@movie, user)  %>
Shows stars of rater per dimensions
<%= rating_for_user @movie, current_user, "Story" %>
<%= rating_for_user @movie, current_user, "Story", {:disable_after_rate => true} %>
View Only User rating, user can't edit it
<%= rating_for_user(@movie, current_user, "Story" , {:disable_after_rate => true, :readonly => true} %>

#in case you user eager load

imdb_style_rating_for(@movie, current_user, options = {:avg => 5}) #passes user rating if not passed, it will query
imdb_style_rating(@movie, options = {:avg => 5}) #passes movie overall avg rating if not passed, it will query

#Rating Sort considering Overall Avg

Movie.betterrate_order() #DESC
Movie.betterrate_order('DESC')
Movie.betterrate_order('ASC')
#Example Output
Movie.betterrate_order('DESC').map(&:id) [4, 1, 5, 6, 7]
Movie.betterrate_order('ASC').map(&:id) [1, 5, 6, 7, 4]
Movie.betterrate_order.map(&:id) [4, 1, 5, 6, 7]

#Get Overall Avg

Movie.betterrate_order('DESC').first.rate_overall_average
Movie.betterrate_order('DESC').eager_load(:rate_overall_average)

#Example Output
Movie.betterrate_order('DESC').first.rate_overall_average.avg #4.5

#Rate Average with Dimensions

Movie.betterrate_order('DESC').eager_load(:rate_average)
Movie.betterrate_order('DESC').first.rate_average
#Example Output
Movie.betterrate_order('DESC').first.rate_average.first.dimension #Action
Movie.betterrate_order('DESC').first.rate_average.first.avg #5.0

#Get rater average

 Movie.betterrate_order('DESC').first.rater_average
 Movie.betterrate_order('DESC').first.rater_average.first
