ExtJS 4: Models with Associations and Stores

由 筅森魡賤 提交于 2019-11-27 18:09:09
Introduction I'm facing an application design problem with the Ext.data.Model class in ExtJS. I will try to develop my ideas to a very common online store scenario here, so you can follow me. I would really appreciate any comments on my thoughts and conclusions! Models Let's suppose you want to map the fact that " Every customer can order multiple products " to ExtJS. From the bare words one can identify these three models involved: Customer , Order , and Product . The Order in this case is what connects Customer s and Product s. Associations I found that ExtJS actually allows you to specify

how to handle session expire basing redis?

由 别来无恙 提交于 2019-11-27 17:24:52
I want to implement a session store based on Redis. I would like to put session data into Redis. But I don't know how to handle session-expire. I can loop through all the redis keys (sessionid) and evaluate the last access time and max idle time, thus I need to load all the keys into the client, and there may be 1000m session keys and may lead to very poor I/O performances. I want to let Redis manage the expire, but there are no listener or callback when the key expire, so it is impossible to trigger HttpSessionListener. Any advice? Didier Spezia So you need your application to be notified

Need to store a 2d list but not using array

由 不羁的心 提交于 2019-11-27 16:32:47
Consider that I have a txt file containing data of the following format: "Home" "A1" "Car" "A2" "Home" "B1" "Home" "A1" "Car" "A2" "Man" "B1" How I can store this kind of data and also in sorted format, without duplicate data? But The first and third element must not be deleted as they are different with 2nd parameter (repetition of second parameter is allowed but not both 1st and 2nd). Please suggest any better collection from Java suitable. Also please give an example as I am new to Java. Best option in Java is a Map<String, String> . As is so urgent, take a look by yourself in the MAP API

How to store an object in a cookie?

由 混江龙づ霸主 提交于 2019-11-27 14:47:17
问题 While this is possible in C#: (User is a L2S class in this instance) User user = // function to get user Session["User"] = user; why this is not possible? User user = // function to get user HttpCookie cookie = new HttpCookie(); cookie.Value = user; and how can it be done? I don't want to store the id of the user within the cookie and then do some validation. Btw, if possible, is it secure to store an object within a cookie rather than only the ID ? 回答1: A cookie is just string data; the only

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . I need a fast, reliable and memory-efficient key--value database for Linux. My keys are about 128 bytes, and the maximum value size can be 128K or 256K. The database subsystem shouldn't use more than about 1 MB of RAM. The total database size is 20G (!), but only a small random fraction of the data is accessed

Compile lua code, store bytecode then load and execute it

由 二次信任 提交于 2019-11-27 05:11:04
问题 I'm trying to compile a lua script that calls some exported functions, save the resulting bytecode to a file and then load this bytecode and execute it, but I haven't found any example on how to do this. Is there any example available on how to do this? How can I do this? Edit: I'm using Lua + Luabind (C++) 回答1: This is all very simple. First, you load the Lua script without executing it. It does not matter if you have connected the Lua state with your exported functions; all you're doing is

Search for a string or part of string in PHP

由 守給你的承諾、 提交于 2019-11-27 04:44:59
问题 I am doing a very small online store application in PHP. So I have an array of maps in PHP. I want to search for a string (a product) in the array. I looked at array_search in PHP and it seems that it only looks for exact match. Do you guys know a better way to do this functionality? Since this is a very small part of what I am actually doing, I was hoping that there was something built in. Any ideas? Thanks! EDIT: The array contains "products" in this format: [6] => SimpleXMLElement Object (

问题 I originally posted this on the Sencha forums here but didn't get any responses (other than my own answer, which I will post soon), so I am going to repost it here and see if I get anymore help. I've been racking my brain on how to filter a TreeStore in 4.0.7. I've tried the following: The model Ext.define('model', { extend: 'Ext.data.Model', fields: [ {name: 'text', type: 'string'}, {name: 'leaf', type: 'bool'}, {name: 'expanded', type: 'bool'}, {name: 'id', type: 'string'} ], hasMany:
