Ok, so I had this working just fine before making a few controller additions and the relocation of some code. I feel like I am missing something really simple here but have spent hours trying to figure out what is going on. Here is the situation.
class Question < ActiveRecord::Base
has_many :sites
end
and
class Sites < ActiveRecord::Base
belongs_to :questions
end
I am trying to display my Sites in order of the sum of the 'like'
column in the Sites Table. From my previous StackOverflow question I had this working when the partial was being called in the /views/sites/index.html.erb
file. I then moved the partial to being called in the /views/questions/show.html.erb file
and it successfully displays the Sites but fails to order them as it did when being called from the Sites view.
I am calling the partial from the /views/questions/show.html.erb file as follows:
<%= render :partial => @question.sites %>
and here is the SitesController#index code
class Si开发者_运维百科tesController < ApplicationController
def index
@sites = @question.sites.all(:select => "sites.*, SUM(likes.like) as like_total",
:joins => "LEFT JOIN likes AS likes ON likes.site_id = sites.id",
:group => "sites.id",
:order => "like_total DESC")
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @sites }
end
end
I think it should be
@sites = @question.sites.all(:select => "sites.*, SUM(likes.like) as like_total",
:joins => "LEFT JOIN likes AS likes ON likes.site_id = sites.id",
:group => "sites.id",
:order => "SUM(likes.like) DESC")
Ah...turns out that I had move the @sites controller code from the SitesController to the QuestionsController Show action. I then had to change my partial in the /views/questions/show.html.erb page from
<%= render :partial => @question.sites %>
to
<%= render :partial => @sites %>
