Django Override Admin change_form.html Template - display associated model in template

Deadly 提交于 2019-11-29 07:17:07
问题 I have a situation where I've overrided the admin_change.html template for a given model. I've created a file such as: /myproject/templates/admin/myapp/mymodel/change_form.html Then, in the overrided change_form.html template, where I am editing an existing object instance, I want to have access to that model instance variable so I can display more information about it. {% extends "admin/change_form.html" %} {% block after_field_sets %}{{ block.super }} Print my model here: {{ mymodel }}

How to extend a typedef parameter in JSDOC?

梦想与她 提交于 2019-11-29 06:45:14
问题 Assuming you have the following code inside a ES6 class (documentation): /** * @typedef Test~options * @type {object.<string>} * @property {array} elements - An array containing elements * @property {number} length - The array length */ /** * @param {Test~options} opt - Option object */ test(opt){ } Now I would like to document another function, let's name it test2 . This function takes exactly the same options object, but needs another property parent . How to document this without

jQuery plugin - update settings after initialization

谁说我不能喝 提交于 2019-11-29 04:49:10
I have a jQuery plugin, and I want to be able to change options on the fly, like this example: $('.element').pwstabs('options','effect',scale) or something simular to it. I tried adding update: function , tried adding Plugin.prototype.update , but still cant figure out how to do that :) Here's the structure of the plugin: ;(function ($, window, document, undefined) { var pluginName = "pwstabs", defaults = { effect: 'scaleout', defaultTab: 1, containerWidth: '100%', tabsPosition: 'horizontal', horizontalPosition: 'top', verticalPosition: 'left', responsive: false, theme: '', rtl: false,

How extend Windows 8 Explorer Ribbon with custom controls?

北城以北 提交于 2019-11-29 04:26:34
As example, I want make simple resizer, where you can select image in explorer and set new dimensions. It is not possible to modify the Windows Explorer 8 ribbon. However, add-ins will not be able to plug into the ribbon UI. This was a difficult engineering choice for us and we expect that many of you will read this and suggest we add the capability--of course if we could get it right this time around we would have done that. A big part of this blog is sharing these choices--tradeoffs--between new features and adding everything we can dream up and finishing. We also think the customization we

Adding the same context menu to multiple activities

I'm trying to figure out how to include common pieces of code in multiple activities. More specifically, I have a context menu that I would like to include in several activities. I saw this, but just don't understand how to extend to multiple activities. http://developer.android.com/guide/topics/ui/menus.html I have this set up as Menu.java public class Menu extends Activity{ // bottom menus public static final int Menu1 = 1; public static final int Menu2 = 2; public static final int Menu3 = 3; public static final int Menu4 = 4; public static final int Menu5 = 5; public static final int Menu6

Is it possible to extend enum in Java 8?

邮差的信 提交于 2019-11-28 18:53:57
Just playing and came up with a sweet way to add functionality to enum s in Java Enum toString() method with this . Some further tinkering allowed me to nearly also add a tidy (i.e. not throwing an exception) reverse look-up but there's a problem. It's reporting: error: valueOf(String) in X cannot implement valueOf(String) in HasValue public enum X implements PoliteEnum, ReverseLookup { overriding method is static Is there a way? The aim here is to silently add (via an interface implementation with a default method like I added politeName in the linked answer) a lookup method that does the

Extending a java ArrayList

℡╲_俬逩灬. 提交于 2019-11-28 18:52:47
I'd like to extend ArrayList to add a few methods for a specific class whose instances would be held by the extended ArrayList. A simplified illustrative code sample is below. This seems sensible to me, but I'm very new to Java and I see other questions which discourage extending ArrayList, for example Extending ArrayList and Creating new methods . I don't know enough Java to understand the objections. In my prior attempt, I ending up creating a number of methods in ThingContainer that were essentially pass-throughs to ArrayList, so extending seemed easier. Is there a better way to do what I'm

deep extend (like jQuery's) for nodeJS

狂风中的少年 提交于 2019-11-28 18:34:25
I am struggling with deep copies of objects in nodeJS. my own extend is crap. underscore's extend is flat. there are rather simple extend variants here on stackexchange, but none are even close to jQuery.extend(true, {}, obj, obj, obj) .. (most are actually terrible and screw up the benefits of asnyc code.) hence, my question: is there a good deep copy for NodeJS? Has anybody ported jQuery's ? You want jQuery's, so just use it: function extend() { var options, name, src, copy, copyIsArray, clone, target = arguments[0] || {}, i = 1, length = arguments.length, deep = false, toString = Object
