阅读更多关于 Doctrine - Add default time stamp to entity like NOW()

问题 Following the Doctrine guidelines I understand how to set a default value for an Entity, but what if I wanted a date/time stamp? http://docs.doctrine-project.org/projects/doctrine-orm/en/2.1/reference/faq.html My problem is my database has a default of NOW() on a field but when I use Doctrine to insert a record the values are null or blank but the rest of the insert happened. Also since Doctrine says to declare the default as a const, this also creates a problem. Suggestions? 回答1: Ok I found

Sf2 : using a service inside an entity

阅读更多关于 Sf2 : using a service inside an entity

问题 i know this has been asked over and over again, i read the topics, but it's always focused on specific cases and i generally try to understand why its not best practise to use a service inside an entity. Given a very simple service : Class Age { private $date1; private $date2; private $format; const ym = "%y years and %m month" const ... // some DateTime()->diff() methods, checking, formating the entry formats, returning different period formats for eg. } and a simple entity : Class People {

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 3 years ago . I really need to see some honest, thoughtful debate on the merits of the currently accepted enterprise application design paradigm. I am not convinced that entity objects should exist. By entity objects I mean the typical things we tend to build for our applications, like

What is the difference between “LINQ to Entities”, “LINQ to SQL” and “LINQ to Dataset”

阅读更多关于 What is the difference between “LINQ to Entities”, “LINQ to SQL” and “LINQ to Dataset”

问题 I've been working for quite a while now with LINQ. However, it remains a bit of a mystery what the real differences are between the mentioned flavours of LINQ. The successful answer will contain a short differentiation between them. What is the main goal of each flavor, what is the benefit, and is there a performance impact... P.S. I know that there are a lot of information sources out there, but I'm looking for a kind of a "cheat sheet" which instructs a newbie where to head for a specific

Get array/list of entities from Doctrine

阅读更多关于 Get array/list of entities from Doctrine

问题 This is probably pretty simple, but I can't find a way to do this. Is there any way to get a list of class names of the entities that Doctrine manages? Something like: $entities = $doctrine->em->getEntities(); where $entities is an array with something like array('User', 'Address', 'PhoneNumber') etc... 回答1: I know this question is old, but in case someone still needs to do it (tested in Doctrine 2.4.0): $classes = array(); $metas = $entityManager->getMetadataFactory()->getAllMetadata();

Unescaping XML entities using XmlReader in .NET?

阅读更多关于 Unescaping XML entities using XmlReader in .NET?

问题 I'm trying to unescape XML entities in a string in .NET (C#), but I don't seem to get it to work correctly. For example, if I have the string AT&T , it should be translated to AT&T . One way is to use HttpUtility.HtmlDecode(), but that's for HTML. So I have two questions about this: Is it safe to use HttpUtility.HtmlDecode() for decoding XML entities? How do I use XmlReader (or something similar) to do this? I have tried the following, but that always returns an empty string: static string
