What is a good way to store large temporary “session” data in a web application

与世无争的帅哥 提交于 2019-12-06 11:01:03
My company has a 3rd party web service we are designing a front end for. The "objects" used by this web service are very large (and variable depending on the number of sub-entities created). The web service does not expose methods to commit/load sub-entities, only the full object hierarchy. The UI itself is split into many sub screens, and master/detail views to be able to efficiently/easily edit the large amount of data. The issue is where to store all the data you aren't currently looking at. Doing the web service commit takes up to 30 seconds for large records, so it is not feasible to use

Remembering a jQuery draggable tool palette position between page refreshes

試著忘記壹切 提交于 2019-12-06 05:49:26
I have a tool palette which shows up when an admin user is logged in to a site. The palette is draggable (via jQueryUI.draggable) and I would like it to remember the position between pages/refreshes... Is there a standard way of doing this, or a plug-in I should be using, or do I need to roll my own (via cookies or something)? Alex Gyoshev Cookies are a fine option - you can use the functions by PPK like this: $('#palette') .css({ top: readCookie("palletteY")*1, left: readCookie("palletteX")*1 }) .draggable({ stop: function (event, ui) { createCookie("palletteX", ui.position.left, 100);

AngularJs ui-router $location or $state?

微笑、不失礼 提交于 2019-12-06 05:38:46
How can I transform this: $location.path('/app/home/' + id).search({x:y}); to this: $state.go('/app/home/' + id).search({x:y}); I tried, but I actually can't get enough information how to achieve that... Radim Köhler There is nice documentation (while deprecated, still really clear) : $state.go(to [, toParams] [, options]) Let's say that the state definitions are looking like this: .state('app', { // parent app url: '/app', ... }) .state('app.home', { url: '/home/:x', // the param named x ... Then you will do $state.go('app.home', {x:y}); This Q&A could help as well: Angular ui-router - how to

Best way to load an application like it was in its previous state when it was terminated

主宰稳场 提交于 2019-12-06 04:51:04
I would like to learn the best practices in reloading the application state, such that when my app is started, it should automatically load the "correct" view/subview when it is opened again. In my particular case, my app has a bunch of view controllers, each taking care of a UITableView. I would like for my app to "jump" to the correct node within my table view hierarchy when it is opened again. Building on what Marc said, assuming you've got a base view controller, and then one or more levels of 'drill-down', load all your view controllers up to the 'current' one using [navigationController

SCTP 库的简述和代码 (3)

Transition methods in state design pattern

帅比萌擦擦* 提交于 2019-12-06 03:40:27
问题 I have a state machine with many states A--B--C--D--E . I have many transitions from C for example to A if some condition is verified. For every state I have a class extending abstract class State and I have a manager that delegates every transition method to state method. The question is "could states call directly manager transition methods?". I have seen on Internet only examples in which there is a main class that knows exactly how many times transition happens (i.e. insertQuarter() ,

How can I prohibit State change from Proposed to Active in TFS Requirement work-item based on value of another field?

£可爱£侵袭症+ 提交于 2019-12-06 03:25:28
I've added department approvals to the standard CMMI-Template Requirement work-item. I'd like to limit the System.State field such that it can only be changed from Proposed to Active when all department approvals are set to "Yes". I've tried the following change to Requirement.xml <FIELD name="State" refname="System.State" type="String" reportable="dimension"> <WHEN field="Approval.Marketing" value="No"> <READONLY /> </WHEN> <WHEN field="Approval.Quality" value="No"> <READONLY /> </WHEN> <WHEN field="Approval.RD" value="No"> <READONLY /> </WHEN> <WHEN field="Approval.System" value="No">

Why does React throw an error when setState method used in a class constructor?

只谈情不闲聊 提交于 2019-12-06 02:50:37
I know that an error is thrown when setting state for a component not yet mounted. Which explains the error I get from using setState function as oppose to explicitly and directly setting the state. import React, {Component} from 'react'; class SearchBar extends Component { constructor(props) { super(props); this.state = {term: ''}; // -> seems to be the agreed means to set initial state // this.setState({term: ''}); // -> generates an error } render() { return ( <div> <input onChange={event => this.setState({term: event.target.value})}/> Value of the input: {this.state.term} </div> ); } } The

Passing compile-time state between nested macros in Clojure

ぐ巨炮叔叔 提交于 2019-12-06 02:49:21
问题 I'm trying to write a macro that can be used both in a global and nested way, like so: ;;; global: (do-stuff 1) ;;; nested, within a "with-context" block: (with-context {:foo :bar} (do-stuff 2) (do-stuff 3)) When used in the nested way, do-stuff should have access to {:foo :bar} set by with-context . I've been able to implement it like this: (def ^:dynamic *ctx* nil) (defmacro with-context [ctx & body] `(binding [*ctx* ~ctx] (do ~@body))) (defmacro do-stuff [v] `(if *ctx* (println "within
