• grunt angularjs doesn't process video files

  - by Daly

  I've set up my grunt file to copy, minify, uglify, revved and all that. It works fine with all media I use, except that recently I added a video to an html file, but it's not being copied to /dist, nor is the html being updated with the versioned file (that is not being copied nor revved). Not sure what I'm missing. Here is the html fragment: <div class="col-xs-4"> <div class="row flowplayer"> <video autoplay> <source type="video/mp4" src="/videos/wedding_planners_bride_smallweb.mp4"> </video> </div> </div> What do I need to add to my gruntfile.js file to process /videos the same way /images are just working out of the box? Thanks

• HQL updates and domain objects

  - by CaptainAwesomePants

  I have what may be a pretty elementary Hibernate question. Do HQL (and/or Criteria) update queries cause updates to live domain objects? And do they automatically flush now-invalid domain objects from the first-level cache? Example: Player playerReference1 = session.get(Player.class,1); session.createQuery("update players set gold = 100").executeUpdate(); //Question #1 -- does playerReference1.getGold() now return 100? Player playerReference2 = session.get(Player.class,1); //Question #2 -- does playerReference2.getGold() return 100, or is it the same exact object? Should I make a practice of evicting all objects that are affected by an HQL update if there's a chance some code will need it later?

• Is it possible to use AutoMapper to wrap methods?

  - by Woj

  I have two classes: public class TestClass1 { public int TestInt { get; set; } public void TestMethod() { // Do something } } public class TestClass2 { public int TestInt { get; set; } public void TestMethod() { // Do something } } I want to create interface that I can use for both classes. The easiest solution is to implement the interface on TestClass1 and TestClass2 but I don;t have access to the implementation of these classes (external dll). I was wondering if I can create new interface and use AutoMapper to map TestClass1 and TestClass2 to ITestInterface: public interface ITestInterface { int TestInt { get; set; } void TestMethod(); }

• JQuery - is at least one checkbox checked

  - by Laramie

  I am in the process of learning JQuery thanks mostly to the positive reference here on Stack Overflow. I need a function that checks all the checkboxes in an element which have the same CSS class. It should returns true if at least one of them is checked. There are also other boxes in the element that are irrelevant to the check. The CSS class is unnecessary and only in place to create a way to identify the checkboxes in the group. It feels like bad practice, so any recommendations about other ways to identify them are welcome.

• Displaying list of objects as single column in a bound gridview (Winforms)?

  - by Carrie Nelson

  I have a gridview that is bound to a datasource on a Windows Form (VB.NET). The grid displays a list of "certifications", and each "certification" can be associated with many languages. So in the grid, I'd like to display "languages" as a column, and display a comma delimited list of the language names for each "certification". In the "certification" class, one of the properties is a list of "language" objects, and each "language" has an ID (guid), name (string), and value (integer). So in the datasource, I have the list of "languages", but I can't figure out how to display them in a column on the grid. The gridview won't let me add the language list property as a column. So is the ONLY way to add a new property on the "certification" class, which returns a string that contains the comma delimited list, and show THAT on the grid? Or is there a way to display that list of "languages"?

  I have the following model setup. from django.db import models from django.contrib.auth.models import User class SomeManager(models.Manager): def friends(self): # return friends bla bla bla class Relationship(models.Model): """(Relationship description)""" from_user = models.ForeignKey(User, related_name='from_user') to_user = models.ForeignKey(User, related_name='to_user') has_requested_friendship = models.BooleanField(default=True) is_friend = models.BooleanField(default=False) objects = SomeManager() relationships = models.ManyToManyField(User, through=Relationship, symmetrical=False) relationships.contribute_to_class(User, 'relationships') Here i take the User object and use contribute_to_class to add 'relationships' to the User object. The relationship show up, but if call User.relationships.friends it should run the friends() method, but its failing. Any ideas how i would do this? Thanks

• Activity gets killed while executing the camera intent

  - by BlackRider

  In my app I call the system camera to take a picture, and then handle the result in onActivityResult. You know, the usual. It used to work, but now my calling activity gets killed while I'm taking the picture. Specifically, onDestroy() is called on my activity right after I press the camera shutter. The photo does get taken & saved (I've checked that the file gets written on the SD card). After I accept the photo, instead of returning to the calling activity and invoking onActivityResult, the previous activity in the activity stack gets called. I see no exceptions in the logcat. My custom exception handler doesn't get called. If it matters, my app also includes a service that listens to GPS updates, but I unregister all the receivers in onPause(). Here's the call stack for MyCallingActivity.onDestroy(): Thread [<1> main] (Suspended (breakpoint at line 303 in NewPlaceDetailsActivity)) NewPlaceDetailsActivity.onDestroy() line: 303 ActivityThread.performDestroyActivity(IBinder, boolean, int, boolean) line: 2663 ActivityThread.handleDestroyActivity(IBinder, boolean, int, boolean) line: 2694 ActivityThread.access$2100(ActivityThread, IBinder, boolean, int, boolean) line: 117 BinderProxy(ActivityThread$H).handleMessage(Message) line: 968 ActivityThread$H(Handler).dispatchMessage(Message) line: 99 Looper.loop() line: 130 ActivityThread.main(String[]) line: 3687 Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method] Method.invoke(Object, Object...) line: 507 ZygoteInit$MethodAndArgsCaller.run() line: 842 ZygoteInit.main(String[]) line: 600 NativeStart.main(String[]) line: not available [native method] This is how I start the camera activity, in case you're wondering: protected void startCamera() { createPhotoDirsIfNeeded(); String fileName = "temp.jpg"; ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, fileName); m_capturedImageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); m_photoFileName = APP_PHOTO_PATH + "/" + DateFormat.format(DATE_FORMAT, Calendar.getInstance().getTime()) + ".jpg"; File picFile = new File(m_photoFileName); if(picFile.exists()) { picFile.delete(); } // start the camera activity Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(picFile)); startActivityForResult(intent, IntentHelper.REQUEST_TAKE_PHOTO); } How can I find out why does my activity get killed, AND removed from the stack instead of being created again?

• django related_name for field clashes.

  - by Absolute0

  I am getting a field clash in my models: class Visit(models.Model): user = models.ForeignKey(User) visitor = models.ForeignKey(User) Error: One or more models did not validate: profiles.visit: Accessor for field 'user' clashes with related field 'User.visit_set'. Add a related_name argument to the definition for 'user'. profiles.visit: Accessor for field 'visitor' clashes with related field 'User.visit_set'. Add a related_name argument to the definition for 'visitor'. what would be a sensible 'related_field' to use on visitor field? This model basically represents the visits that take place to a particular user's profile. Also should I replace any of the ForeignKey's with a ManyToManyField? The logic is a bit confusing. Edit: This seems to fix it, but I am unsure if its what I want. :) class Visit(models.Model): user = models.ForeignKey(User) visitor = models.ForeignKey(User, related_name='visitors')

• Can running object be garbage collected?

  - by Kugel

  I have a simple class: public class Runner { public void RunAndForget(RunDelegate method) { ThreadPool.QueueUserWorkItem(new WaitCallback(Run), method); } private void Run(object o) { ((RunDelegate )o).Invoke(); } } And if I use this like so: private void RunSomethingASync() { Runner runner = new Runner(); runner.FireAndForget(new RunDelegate(Something)); } Is there any danger using it like this? My C++ guts tell me that runner object should be destroyed after RunSomethingASync is finished. Am I right? What happens then to the method running on different thread? Or perhaps it is other way around and runner will not be collected? That would be a problem considering I may call RunSomethingASync() many times.

• Methodology for a Rails app

  - by Aaron Vegh

  I'm undertaking a rather large conversion from a legacy database-driven Windows app to a Rails app. Because of the large number of forms and database tables involved, I want to make sure I've got the right methodology before getting too far. My chief concern is minimizing the amount of code I have to write. There are many models that interact together, and I want to make sure I'm using them correctly. Here's a simplified set of models: class Patient < ActiveRecord::Base has_many :PatientAddresses has_many :PatientFileStatuses end class PatientAddress < ActiveRecord::Base belongs_to :Patient end class PatientFileStatus < ActiveRecord::Base belongs_to :Patient end The controller determines if there's a Patient selected; everything else is based on that. In the view, I will be needing data from each of these models. But it seems like I have to write an instance variable in my controller for every attribute that I want to use. So I start writing code like this: @patient = Patient.find(session[:patient]) @patient_addresses = @patient.PatientAddresses @patient_file_statuses = @patient.PatientFileStatuses @enrollment_received_when = @patient_file_statuses[0].EnrollmentReceivedWhen @consent_received = @patient_file_statuses[0].ConsentReceived @consent_received_when = @patient_file_statuses[0].ConsentReceivedWhen The first three lines grab the Patient model and its relations. The next three lines are examples of my providing values to the view from one of those relations. The view has a combination of text fields and select fields to show the data above. For example: <%= select("patientfilestatus", "ConsentReceived", {"val1"="val1", "val2"="val2", "Written"="Written"}, :include_blank=true )% <%= calendar_date_select_tag "patient_file_statuses[EnrollmentReceivedWhen]", @enrollment_complete_when, :popup=:force % (BTW, the select tag isn't really working; I think I have to use collection_select?) My questions are: Do I have to manually declare the value of every instance variable in the controller, or can/should I do it within the view? What is the proper technique for displaying a select tag for data that's not the primary model? When I go to save changes to this form, will I have to manually pick out the attributes for each model and save them individually? Or is there a way to name the fields such that ActiveRecord does the right thing? Thanks in advance, Aaron.

• Why is there no parameter contra-variance for overriding?

  - by Oak

  C++ and Java support return-type covariance when overriding methods. Neither, however, support contra-variance in parameter types - instead, it translates to overloading (Java) or hiding (C++). Why is that? It seems to me that there is no harm in allowing that. I can find one reason for it in Java - since it has the "choose-the-most-specific-version" mechanism for overloading anyway - but can't think of any reason for C++. Example (Java): class A { public void f(String s) {...} } class B extends A { public void f(Object o) {...} // Why doesn't this override A.f? }

• Decoding mysql_real_escape_string() for outputting HTML

  - by Peter

  I'm trying to protect myself from sql injection and am using: mysql_real_escape_string($string); When posting HTML it looks something like this: <span class="\&quot;className\&quot;"> <p class="\&quot;pClass\&quot;" id="\&quot;pId\&quot;"></p> </span> I'm not sure how many other variations real_escape_string adds so don't want to just replace a few and miss others... How do I "decode" this back into correctly formatted HTML, with something like: html_entity_decode(stripslashes($string));

• PHP Type Hinting: array supported, object NOT?

  - by Marius Burz

  Am I missing something or there really is no support for generic object type hinting in PHP 5.x? I find it really strange that hinting arrays is supported while hinting objects is not, at least not out of the box. I'd like to have something like this: function foo(object $o) Just as we have: function foo(array $o) Example of possible use: methods of an objects collection class. Workaround: using an interface "Object" implemented by all classes or extending all classes from a generic class "Object" and writing something like this: function foo(Object $o) Well, that just ain't cute. Edit: somebody suggested in a deleted post using stdClass. It doesn't work: Catchable fatal error: Argument 1 passed to c::add() must be an instance of stdClass, instance of b given

• Should I skip authorization, with CanCan, of an action that instantiates a resource?

  - by irkenInvader

  I am writing a web app to pick random lists of cards from larger, complete sets of cards. I have a Card model and a CardSet model. Both models have a full RESTful set of 7 actions (:index, :new, :show, etc). The CardSetsController has an extra action for creating random sets: :random. # app/models/card_set.rb class CardSet < ActiveRecord::Base belongs_to :creator, :class_name => "User" has_many :memberships has_many :cards, :through => :memberships # app/models/card.rb class Card < ActiveRecord::Base belongs_to :creator, :class_name => "User" has_many :memberships has_many :card_sets, :through => :memberships I have added Devise for authentication and CanCan for authorizations. I have users with an 'editor' role. Editors are allowed to create new CardSets. Guest users (Users who have not logged in) can only use the :index and :show actions. These authorizations are working as designed. Editors can currently use both the :random and the :new actions without any problems. Guest users, as expected, cannot. # app/controllers/card_sets_controller.rb class CardSetsController < ApplicationController before_filter :authenticate_user!, :except => [:show, :index] load_and_authorize_resource I want to allow guest users to use the :random action, but not the :new action. In other words, they can see new random sets, but not save them. The "Save" button on the :random action's view is hidden (as designed) from the guest users. The problem is, the first thing the :random action does is build a new instance of the CardSet model to fill out the view. When cancan tries to load_and_authorize_resource a new CardSet, it throws a CanCan::AccessDenied exception. Therefore, the view never loads and the guest user is served a "You need to sign in or sign up before continuing" message. # app/controllers/card_sets_controllers.rb def random @card_set = CardSet.new( :name => "New Set of 10", :set_type => "Set of 10" ) I realize that I can tell load_and_authorize_resource to skip the :random action by passing :except => :random to the call, but that just feels "wrong" for some reason. What's the "right" way to do this? Should I create the new random set without instantiating a new CardSet? Should I go ahead and add the exception?

• Disallow private constructor invocation in friend function

• Was delegates static by default?

How is it possible?

• Accessing Session and IPrinciple data in a Master View in Asp.Net MCV

  - by bplus

  I currently have a abstract controller class that I all my controllers inherit from. In my master page I want to be able to access some data that will be in Session and also the currently user (IPrinciple). I read that I could use the contructor of by abstract base controller class, that is I could do something like public BaseController() { ViewData["SomeData"] = Session["SomeData"]; ViewData["UserName"] = this.User.Identity.Name; } I could then access ViewData["UserName"] etc from my master page. My problem is that both Session and User are null at this point. Does anybody know of a different approach? Thanks in advance.

• ASP.NET MVC: How can I explain an invalid type violation to an end-user with Html.ValidationSummary?

  - by Terminal Frost

  Serious n00b warning here; please take mercy! So I finished the Nerd Dinner MVC Tutorial and I'm now in the process of converting a VB.NET application to ASP.NET MVC using the Nerd Dinner program as a sort of rough template. I am using the "IsValid / GetRuleViolations()" pattern to identify invalid user input or values that violate business rules. I am using LINQ to SQL and am taking advantage of the "OnValidate()" hook that allows me to run the validation and throw an application exception upon trying to save changes to the database via the CustomerRepository class. Anyway, everything works well, except that by the time the form values reach my validation method invalid types have already been converted to a default or existing value. (I have a "StreetNumber" property that is an integer, though I imagine this would be a problem for DateTime or any other non-strings as well.) Now, I am guessing that the UpdateModel() method throws an exception and then alters the value because the Html.ValidationMessage is displayed next to the StreetNumber field but my validation method never sees the original input. There are two problems with this: While the Html.ValidationMessage does signal that something is wrong, there is no corresponding entry in the Html.ValidationSummary. If I could even get the exception message to show up there indicating an invalid cast or something that would be better than nothing. My validation method which resides in my Customer partial class never sees the original user input so I do not know if the problem is a missing entry or an invalid type. I can't figure out how I can keep my validation logic nice and neat in one place and still get access to the form values. I could of course write some logic in the View that processes the user input, however that seems like the exact opposite of what I should be doing with MVC. Do I need a new validation pattern or is there some way to pass the original form values to my model class for processing? CustomerController Code // POST: /Customers/Edit/[id] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(int id, FormCollection formValues) { Customer customer = customerRepository.GetCustomer(id); try { UpdateModel(customer); customerRepository.Save(); return RedirectToAction("Details", new { id = customer.AccountID }); } catch { foreach (var issue in customer.GetRuleViolations()) ModelState.AddModelError(issue.PropertyName, issue.ErrorMessage); } return View(customer); }

• VB.NET For Each steps into loop body for an IEnumerable collection! How? Why?

  - by Paul Sasik

  This is weird. I have a class that inherits from IEnumrable whose Count property is reporting 0 (zero) elements but the For Each loop steps into the loop body and tries to use the variable where it should just be moving on. My code: On Error Resume Next Dim d As Foo For Each d In fooCollection ' use d and throws an exception Next d Weirder still, every time d is accessed i get an exception thrown in the output window: A first chance exception of type 'System.NullReferenceException' but i'm not stopping on the exception (not in a try/catch block). Is "On Error Resume Next" causing this weirdness? Weirdness found: Per Rowland's and JohnH's comments i checked the Foo class: The GetEnumerator method inside of Foo didn't actually return anything! It had an empty body. That coupled with the On Error Resume Next before the loop caused the havoc! Wow this was ugly. Thanks for the clues guys!
