由 情到浓时终转凉″ 提交于 2019-12-03 12:54:32
i need to extend an entity, with the same characteristics without using abstract classes. can i code something like below? @Entity @Table(name="ABC") @SequenceGenerator(sequenceName="SEQ_ABC",name="idGenerator",allocationSize=1) public class Abc { .. // define members } @Entity @Table(name="EX_ABC") public class ExAbc extends Abs { .. // define extras.. } thx in advance Yes, this one works without any problems. However you should have a look at the inheritance annotation. What's the problem: You have a table "Abc" which contains field1,filed2; Then you have ExAbc which contains the fields of

Make DateTime::createFromFormat() return child class instead of parent

由 旧巷老猫 提交于 2019-12-03 11:33:21
I'm extending DateTime do add some useful methods and constants. When using new to create a new object everything is fine but when using the static method createFromFormat it always returns the original DateTime object and of course none of the child methods are available. I am using the following code to circumvent this issue. Is this the best approach? namespace NoiseLabs\DateTime; class DateTime extends \DateTime { static public function createFromFormat($format, $time) { $ext_dt = new self(); $ext_dt->setTimestamp(parent::createFromFormat($format, time)->getTimestamp()); return $ext_dt; }

Add properties to stdClass object from another object

由 纵饮孤独 提交于 2019-12-03 11:20:13
I would like to be able to do the following: $obj = new stdClass; $obj->status = "success"; $obj2 = new stdClass; $obj2->message = "OK"; How can I extend $obj so that it contains the properties of $obj2, eg: $obj->status //"success" $obj->message // "OK" I know I could use an array, add all properties to the array and then cast that back to object, but is there a more elegant way, something like this: extend($obj, $obj2); //adds all properties from $obj2 to $obj Thanks! This is more along the lines of they way that you didn't want to do it.... $extended = (object) array_merge((array)$obj,

Extend ES6 plugin to jQuery prototype

由 三世轮回 提交于 2019-12-03 07:32:24
问题 I would like ask some help because i can't convert my classic jQuery (v2) plugin in ES6 with module and class. In ECMAScript 5, we can attach jQuery plugin into jQuery prototype like this : app.js - jQuery loaded via HTML <script> tag $.fn.myPlugin = function() {}; $('div').myPlugin(); And it works :) . In ES6, I would write something like this: myPlugin.es6 : import $ from 'jquery'; export default class myPlugin extends $ { // Could i use constructor() method ??? } app.es6 : import $ from

Putting separate python packages into same namespace?

问题 I'm developing a python framework that would have "addons" written as separate packages. I.e.: import myframework from myframework.addons import foo, bar Now, what I'm trying to arrange is so that these addons can be distributed separately from core framework and injected into myframework.addons namespace. Currently my best solution to this is the following. An add-on would be deployed (most likely into {python_version}/site-packages/ like so: fooext/ fooext/__init__.py fooext/myframework/

django template: Is extended template able to change css in parent page?

由 不羁岁月 提交于 2019-12-03 03:48:48
I have two django template pages, one of them is "base.html", with basic html tags setup as a base template. Now I have a page "child.html" that extends it, with something like {% extends "base.html" %} in it. Now I have to change <body> background color for this particular page, so in the css of "child.html" I wrote: body { background-color: #000000; /* some other css here */ } But the body doesn't seem to respond to any changes. I think I must have missed something. Please help, thanks. Edit: In "child.html", I simply have <link rel="stylesheet" type="text/css" href="/site-media/css/template

Django中模板编码引发extend的问题

由 Deadly 提交于 2019-12-02 18:47:42
用django1.5的模板继承的时候遇到一个很诡异的问题: 用{% extend %}继承父模板后，在chrome中查看源码， <head> 中的内容诡异的到 <body> 标签中了，各种排查都不行。 最后发现是模板文件格式为dos的，换行符\r\n，用dos2unix转一下就OK了，这个是个坑啊，记一下。 来源： oschina 链接： https://my.oschina.net/u/266979/blog/165696

Type error when trying to extend a list in Python

由 落花浮王杯 提交于 2019-12-02 17:26:45
问题 I need to understand why : years = range(2010,2016) years.append(0) is possible, returning : [2010,2011,2012,2013,2014,2015,0] and years = range(2010,2016).append(0) or years = [0].extend(range(2010,2016)) doesn't work ? I understand that it is a type error from the message I got. But I'd like to have a bit more explanations behind that. 回答1: You are storing the result of the list.append() or list.extend() method; both alter the list in place and return None . They do not return the list
