• PHP Sort a multidimensional array by element containing date

  - by user270797

  I have an array such as: Array ( [0] => Array ( [id] => 2 [type] => comment [text] => hey [datetime] => 2010-05-15 11:29:45 ) [1] => Array ( [id] => 3 [type] => status [text] => oi [datetime] => 2010-05-26 15:59:53 ) [2] => Array ( [id] => 4 [type] => status [text] => yeww [datetime] => 2010-05-26 16:04:24 ) ) Can anyone suggest a way to sort/order this based on the datetime element?

• Mapping child objects in fluent nhibernate to a read-only view

  - by grenade

  Given that I am implementing a read-only UI, how do I create a ClassMap for Shop: public class Shop { public int Id { get; set; } public City City { get; set; } } public class City { public string Name { get; set; } public string CountryCode { get; set; } } The DB interface for Shops is a View containing 3 columns (ShopId, CityName, CountryCode). I was hoping to do something like this: public sealed class ShopMap : ClassMap<Shop> { public ShopMap() { Table("Shop"); Id(x => x.Id, "ShopId"); Map(x => x.City.Name, "CityName"); Map(x => x.City.CountryCode, "CountryCode"); } } Will fluent auto-instantiate Shop.City?

• How to sort list items for Date field value (Apex, Salesforce)

  With Salesforce's Apex, is there any way to sort list items, for Date field value.

• EF2: Is there a way to add an Entity to EntityCollection without having to load related Entity?

  - by mutex

  I can set an EntityReference on an entity without having to load the relevent entity as follows: this.CategoryReference.EntityKey = new EntityKey("MyEntities.CategorySet", "Id", 12); So I can set the Category for the entity I'm dealing with to whatever category has id 12 without having to hit the database. But is there a way to do this or something similar on an EntityCollection? So if I now have multiple categories instead of just one, I want to now do something like the following, though it doesn't work: // stand-in category var categoryStandIn = new Category { EntityKey = new EntityKey("MyEntities.CategorySet", "Id", 12) } this.Categories.Add(categoryStandIn);

• Why is the this-pointer needed to access inherited attributes?

  - by Shadow

  Hi, assume the following class is given: class Base{ public: Base() {} Base( const Base& b) : base_attr(b.base_attr) {} void someBaseFunction() { .... } protected: SomeType base_attr; }; When I want a class to inherit from this one and include a new attribute for the derived class, I would write: class Derived: public Base { public: Derived() {} Derived( const Derived& d ) : derived_attr(d.derived_attr) { this->base_attr = d.base_attr; } void SomeDerivedFunction() { .... } private: SomeOtherType derived_attr; }; This works for me (let's ignore eventually missing semicolons or such please). However, when I remove the "this-" in the copy constructor of the derived class, the compiler complains that "'base_attr' was not declared in this scope". I thought that, when inheriting from a class, the protected attributes would then also be accessible directly. I did not know that the "this-" pointer was needed. I am now confused if it is actually correct what I am doing there, especially the copy-constructor of the Derived-class. Because each Derived object is supposed to have a base_attr and a derived_attr and they obviously need to be initialized/set correctly. And because Derived is inheriting from Base, I don't want to explicitly include an attribute named "base_attr" in the Derived-class. IMHO doing so would generally destroy the idea behind inheritance, as everything would have to be defined again. EDIT Thank you all for the quick answers. I completely forgot the fact that the classes actually are templates. Please, see the new examples below, which are actually compiling when including "this-" and are failing when omiting "this-" in the copy-constructor of the Derived-class: Base-class: #include <iostream> template<class T> class Base{ public: Base() : base_attr(0) {} Base( const Base& b) : base_attr(b.base_attr) {} void baseIncrement() { ++base_attr; } void printAttr() { std::cout << "Base Attribute: " << base_attr << std::endl; } protected: T base_attr; }; Derived-class: #include "base.hpp" template< class T > class Derived: public Base<T>{ public: Derived() : derived_attr(1) {} Derived( const Derived& d) : derived_attr(d.derived_attr) { this->base_attr = d.base_attr; } void derivedIncrement() { ++derived_attr; } protected: T derived_attr; }; and for completeness also the main function: #include "derived.hpp" int main() { Derived<int> d; d.printAttr(); d.baseIncrement(); d.printAttr(); Derived<int> d2(d); d2.printAttr(); return 0; }; I am using g++-4.3.4. Although I understood now that it seems to come from the fact that I use template-class definitions, I did not quite understand what is causing the problem when using templates and why it works when not using templates. Could someone please further clarify this?

• Error in MySQL Workbench Forward Engineered Stored Procedures

  - by colithium

  I am using MySQL Workbench (5.1.18 OSS rev 4456) to forward engineer a SQL CREATE script. For every stored procedure, the automatic process outputs something like: DELIMITER // USE DB_Name// DB_Name// DROP procedure IF EXISTS `DB_Name`.`SP_Name` // USE DB_Name// DB_Name// CREATE PROCEDURE `DB_Name`.`SP_Name` (id INT) BEGIN SELECT * FROM Table_Name WHERE Id = id; END// The two lines that are simply the database name followed by the delimiter are errors and are reported as such when running the script. As long as they are ignored, it looks like everything gets created just fine. But why would it add those lines? I am creating the database in the WAMP environment which uses MySQL 5.1.36

• Why is django admin not accepting Nullable foreign keys?

  - by p.g.l.hall

  Here is a simplified version of one of my models: class ImportRule(models.Model): feed = models.ForeignKey(Feed) name = models.CharField(max_length=255) feed_provider_category = models.ForeignKey(FeedProviderCategory, null=True) target_subcategories = models.ManyToManyField(Subcategory) This class manages a rule for importing a list of items from a feed into the database. The admin system won't let me add an ImportRule without selecting a feed_provider_category despite it being declared in the model as nullable. The database (SQLite at the moment) even checks out ok: >>> .schema ... CREATE TABLE "someapp_importrule" ( "id" integer NOT NULL PRIMARY KEY, "feed_id" integer NOT NULL REFERENCES "someapp_feed" ("id"), "name" varchar(255) NOT NULL, "feed_provider_category_id" integer REFERENCES "someapp_feedprovidercategory" ("id"), ); ... I can create the object in the python shell easily enough: f = Feed.objects.get(pk=1) i = ImportRule(name='test', feed=f) i.save() ...but the admin system won't let me edit it, of course. How can I get the admin to let me edit/create objects without specifying that foreign key?

• HTML/CSS Div placing

  - by Andreas Carlbom

  Yo. There's a tendency in placing divs to follow each other vertically, but what i'm trying to accomplish right now is to is basically to place a number of divs (two) inside a parent div like so: <div id='parent'><div id='onediv'></div> <div id='anotherone'></div> </div> And i'd like to place 'anotherone' just to the right of 'onediv'. Sadly, float:right is pretty much ruining the layout with the divs popping out of their parent divs and whatnot. Any suggestions are welcome. Edit: It might be worth noting that the parent div and 'anotherone' has no height elements at all, with 'onediv' planned to be thought as the "height support" div, allowing the contents of 'anotherone' to make the parent div larger at will.

• Creating/populating Javascript custom object

  I've created an ashx page which is going to serve me an XML document full of basic user information. I'm not sure which is the best way to go about creating and populating my custom javascript object. I've seen them created in two ways: function User() { this.Id; this.FirstName; this.LastName; this.Title; } and var User2 = { Id: null, FirstName: null, LastName: null, Title: null } I could populate each of these by doing something like: //first object User.Id = 1 //second object User2.FirstName = 'John' Is one method of creating the object better than the other?

• Ado.Net Entity produces "namespace cannot be found"

  - by Dave

  I've seen several possible solutions to this, but none have worked for me. After adding a ADO.NET Entity Data Model to my .Net Forms C# web project, I am unable to use it. Perhaps I made a mistake adding it? The name of the file added is QcFormData.edmx. In my code, perhaps I'm instantiating it incorrectly? I tried adding the line: QcFormDataContainer db = new QcFormDataContainer(); It appears in Intellisense, but when compiling I get the error : Error 13 The type or namespace name 'QcFormDataContainer' could not be found (are you missing a using directive or an assembly reference?) I've followed the suggestions that I found online that did not help: 1) made sure there is "using System.Data.Entity" 2) made sure the dll exists. 3) made sure the reference exists. 4) one post said use using System.Web.Data.Entity; but I do not see that available.

• In Rails, how can a record belong_to a single user, but also have multiple "secondary" users?

  - by Kuro

  In my app, I have a User model and a Project model. A user has_many assignments and each project belongs_to a user. But along with each project having an owner, the user who created it, I would like the owner be able to share it with others (so that the project gets shown on the other users' account along with their own). I imagine having to use has_many :through, and setting up a projects_users table with a user_id and a project_id. And I guess this would be the end result? Project.first.user # The creator of the project => #<User id: 1, name: 'andrew', etc...> Project.first.users # The users that the creator chose to share it with => [#<User id: 2 ...>, #<User id: 3 ...>] How would I go about doing this? Thanks!
