store

I need to store a recursive tree structure. A linked list. So all the objects are the same. Each has a pointer to a parent object and each has an array of child objects. Can I store such a structure in Mongo. i.e. A Mongo collection of parent objects, each object holds within it a Mongo collection of child objects. $a = $MyCollection->findOne(**some conditions)->Childs->find(...) You cant store collections in collections. But you can store ids that reference objects in other collections. You would have to resolve the id to the document or element and then if that element stores more ids you

My application makes use of the RijndaelManaged class to encrypt data. As a part of this encryption, I use a SecureString object loaded with a password which get's get converted to a byte array and loaded into the RajindaelManaged object's Key at runtime. The question I have is the storage of this SecureString. A user entered password can be entered at run-time, and that can be "securely" loaded into a SecureString object, but if no user entered password is given, then I need to default to something. So ultimately the quesiton comes down to: If I have to have some known string or byte array to

I'm doing a fairly complex emberjs application, and tying it to a backend of APIs. The API calls are not usually tied to any particular model, but may return objects of various types in different sections of the response, e.g. a call to Events API would return events, but also return media assets and individuals involved in those events. I've just started with the project, and I'd like to get some expert guidance on how best to separate concerns to have a clean maintainable code base. The way I am approaching this is: Models : essentially handle records with their fields, and other computed

In extjs3.x I used the stores baseParams config property to specify parameters used to load the store. This property no longer exists in extjs 4. What should I do instead of this? Also in extjs3 I was able to specify wether the stores proxy was a GET or a POST method by using the proxy method config property. What should I do instead of this? My ExtJs 3 code -> var store = new Ext.data.JsonStore({ root: 'Data', baseParams: { StartDate: '', EndDate: ''' },//baseParams proxy: new Ext.data.HttpProxy({ url: 'Time/Timesheet', method: 'POST' })//proxy });//new Ext.data.JsonStore You need to use the

I've been learning Redux and a part I'm unclear of is, how do I make a determination between using react state vs redux store and then dispatching actions. from my reading so far it looks like I could use React state in place of Redux store and still get things done. I understand the separation of concerns with using Redux store and just having 1 container component and the rest of it as stateless component but how do I make the determination of when to use React state Vs redux store is not very clear to me. Can someone please help? Thanks! If the state doesn't need to be shared with other

I have been working on an iOS app for some time, all of a sudden I am getting the following crash every time I run the app in the iOS 5.1 Simulator. The App does not use Core Data and I am not sure what brought this about. I have deleted the app from the simulator, done Clean, and a rebuild but nothing seems to help. Unable to load persistent store at URL 'file://localhost/Users/jcottrell/Library/Application%20Support/iPhone%20Simulator/5.1/Library/Keyboard/UserDictionary.sqlite' ({ metadata = { NSPersistenceFrameworkVersion = 407; NSStoreModelVersionHashes = { UserDictionaryEntry = <f0c9025b

I'm using ember to display data received from my golang server. The data are in JSON form. so I opened a websocket and tried to push the message received in the store but i got this error: Uncaught TypeError: undefined is not a function this is my app.js: App = Ember.Application.create({ LOG_TRANSITIONS: true }) /******************************* Post Template **************************************/ //Define a route for the template "post" App.Router.map(function() { this.route("post", { path: "/post" }); }); //Post Model App.Post = DS.Model.extend({ name: DS.attr('string' ), number: DS.attr(
