Rails category (or filter) links in same controller?
ruby-on-rails,ruby,hyperlink,model,controller
belongs_to is defined in ActiveRecord::Associations, which is part of ActiveRecord. You are manually including ActiveModel::Model which doesn't offer any association-related capabilities. Includes the required interface for an object to interact with ActionPack, using different ActiveModel modules. It includes model name introspections, conversions, translations and validations. Besides that, it allows you...
php function to check when an uploaded image has been in the directory for longer than a day
php,file-upload,controller,cron,unlink
Looks like you have inconsistent directory names. Try this: public function delete_gallery_images() { $dirName = '../public/images/gallery_images/files/'; $dir = opendir($dirName); if ($dir) { // Read directory contents while (false !== ($file = readdir($dir))) { if($file != "." && $file != "..") { // Check the create time of each file (older...
Silex can't find Controller Class
Sigh, it was a capitalization issue. My macbook has a case insensitive filesystem and my linux VPS has a case sensitive filesystem so when deploying to Linux I had to capitalize the directories in my project so that Silex could correctly resolve the controllers.
AngularJS - controller doesn't get data from service when using $http
angularjs,http,service,controller,is-empty
You have to learn about promises: http://chariotsolutions.com/blog/post/angularjs-corner-using-promises-q-handle-asynchronous-calls/ In the service you should return directly the promise of the call to the $http-Service: this.getTrips = function() { return $http.get('trips.json').then(function (response) { trips = response.data; return trips; }); }; In the controller you have then to call the then-method to access the...

Resolve promise in service without callback in controller
angularjs,callback,controller,promise,angular-promise
My best practice with regards to services requesting data and returning promises is: return a promise (in DataService, return deferred.promise) in the controller, call DataService.getData(3).then(, ) So I would not pass a callback to a service function that uses a promise. The more difficult question is what should the service...

Accessing child functions/properties with arranged content in Ember.js
javascript,ember.js,controller
I would move the imageUrl property to the model: App.Post = DS.Model.extend({ ... imageName: DS.attr('string'), imageUrl: Ember.computed('id', 'imageName', function() { var id = this.get('id'); var postImageRoot = "images/posts/" + id + "/"; var imageName = this.get('imageName'); return postImageRoot + imageName; }) }); http://emberjs.jsbin.com/nohazilegi/1/...
Call rendering from another controller
ruby-on-rails,ruby,controller,render
You need to explicitly build the output that you need in the all controller action, rather than trying to join the outputs of other actions. Two approaches: Retrieve the items you want with two database calls, join them together into one big set of list items, then render the list...
