ruby on rails - How to eager load with a condition -

-

i have classic post has_many relationship on comments. want fetch of approved posts related comments have been approved. have approved scope in place each not sure how enable on comments.

this have far returns comments approved postings. best way without having specify condition on has_many limit use of association other queries.

post.approved.includes(:comments)

your example used in documentation. should use association:

class post < activerecord::base   has_many :approved_comments, :class_name => 'comment', :conditions => ['approved = ?', true] end  post.includes(:approved_comments)

ember.js - EmberJS Model find not up-to-date with underlying store -

-
for simple overview screen have developed route sets controller app.location.find(). app.locationsindexroute = ember.route.extend({ setupcontroller: function(controller) { controller.set('content', app.location.find()); }, rendertemplate: function() { this.render('locations.index',{into:'application'}); } }); i naively assumed go store , fetch me records, giving me up-to-date view of records. apparently not.... when external process starts removing records database, app.location.find() keeps on returning these deleted records.
