  • App Engine: how would you... snapshotting entities

    - by Andrew B.
    Let's say you have two kinds, Message and Contact, related by a db.ListProperty of keys on Message. A user creates a message, adds some contacts as recipients, and emails the message. Later, the user deletes one of the contact entities that was a recipient of the message. Our application should delete the appropriate Contact entity, but we want to preserve the original recipient list for the message that was sent for the user's records. In essence, we want a snapshot of the message entity at the time it was sent. If we naively delete the contact entity, though, we lose snapshot integrity; if not, we are left with an invalid key. How would you handle this situation, either in controller logic or model changes? class User(db.Model): email = db.EmailProperty(required=True) class Contact(db.Model): email = db.EmailProperty(required=True) user = db.ReferenceProperty(User, collection_name='contacts') class Message(db.Model): recipients = db.ListProperty(db.Key) # contacts sender = db.ReferenceProperty(User, collection_name='messages') body = db.TextProperty() is_emailed = db.BooleanProperty(default=False)

  • NHibernateUnitOfWork + ASP.Net MVC

    - by Felipe
    Hi Guys, hows it going? I'm in my first time with DDD, so I'm begginer! So, let's take it's very simple :D I developed an application using asp.net mvc 2 , ddd and nhibernate. I have a domain model in a class library, my repositories in another class library, and an asp.net mvc 2 application. My Repository base class, I have a construct that I inject and dependency (my unique ISessionFactory object started in global.asax), the code is: public class Repository<T> : IRepository<T> where T : Entidade { protected ISessionFactory SessionFactory { get; private set; } protected ISession Session { get { return SessionFactory.GetCurrentSession(); } } protected Repository(ISessionFactory sessionFactory) { SessionFactory = sessionFactory; } public void Save(T entity) { Session.SaveOrUpdate(entity); } public void Delete(T entity) { Session.Delete(entity); } public T Get(long key) { return Session.Get<T>(key); } public IList<T> FindAll() { return Session.CreateCriteria(typeof(T)).SetCacheable(true).List<T>(); } } And After I have the spefic repositories, like this: public class DocumentRepository : Repository<Domain.Document>, IDocumentRepository { // constructor public DocumentRepository (ISessionFactory sessionFactory) : base(sessionFactory) { } public IList<Domain.Document> GetByType(int idType) { var result = Session.CreateQuery("from Document d where d.Type.Id = :IdType") .SetParameter("IdType", idType) .List<Domain.Document>(); return result; } } there is not control of transaction in this code, and it's working fine, but, I would like to make something to control this repositories in my controller of asp.net mvc, something simple, like this: using (var tx = /* what can I put here ? */) { try { _repositoryA.Save(objA); _repositoryB.Save(objB); _repositotyC.Delete(objC); /* ... others tasks ... */ tx.Commit(); } catch { tx.RollBack(); } } I've heared about NHibernateUnitOfWork, but i don't know :(, How Can I configure NHibernateUnitOfWork to work with my repositories ? Should I change the my simple repository ? Sugestions are welcome! So, thanks if somebody read to here! If can help me, I appretiate! PS: Sorry for my english! bye =D

  • 2 column div layout: right column fixed width, left fluid, height relative to eachother

    - by Henrik
    I want a layout with two columns, two divs, where the left one has fluid width and the right one has fixed width. So far so good - see jsfiddle below - however, the height of the right column must be in relation to the height of the left column. So that if I have some content in the fluid column and would resize the browser window, thereby increasing or decreasing the height of the left column, the right one should follow and getting the same height. What I got so far: http://jsfiddle.net/henrikandersson/vnUdc/2/ Edit: Resolved, see comment below

  • jQuery UI Themes

    - by Theopile
    So I downloaded a jQuery UI Theme and link it, but it looks nothing like the them on the site. The buttons are huge and so is the text. <link rel="stylesheet" type="text/css" href="/css/trontastic/jquery-ui-1.8.2.custom.css"> $('#Delete').dialog({ modal: true, autoOpen: false, title: "Delete?", buttons: { "Yes": function(){ $(this).dialog('close'); $('li#'+$id).remove(); $('.nav').sortUpdate(); }, "No":function(){ $(this).dialog('close'); } }, draggable: false, resizable: false }); Am I missing something or is there addition css that I have to handcode?

  • problem in `delete-directory` with enabled `delete-by-removing-to-trash`

    - by Andreo
    There is a strange behavior of delete-directory function with enabled flag delete-by-removing-to-trash. It deletes files one by one instead of applying move-file-to-trash to the directory. As a result emacs deletes big directories slowly and there are many files in the trash after deleting, so it is impossible to restore the directory. Example: Directory structure: ddd/ ccc/ 1.txt There are three files in the trash after deleting ddd: trash/ ddd/ ccc/ 1.txt instead of one: trash/ ddd/ It is very slow, because emacs traverse directory recursively. I can't restore deleted directory. What i need is exactly the same behavior as of move-file-to-trash. But it should be transparent (i.e. 'D x' in dired mode). How to solve the problem? As a temporary solution i see the making advice function for `delete-directory'.

  • changing order of items in tkinter listbox

    - by user1104854
    Is there an easier way to change the order of items in a tkinter listbox than deleting the values for specific key, then re-entering new info? For example, I want to be able to re-arrange items in a listbox. If I want to swap the position of two, this is what I've done. It works, but I just want to see if there's a quicker way to do this. def moveup(self,selection): value1 = int(selection[0]) - 1 #value to be moved down one position value2 = selection #value to be moved up one position nameAbove = self.fileListSorted.get(value1) #name to be moved down nameBelow = self.fileListSorted.get(value2) #name to be moved up self.fileListSorted.delete(value1,value1) self.fileListSorted.insert(value1,nameBelow) self.fileListSorted.delete(value2,value2) self.fileListSorted.insert(value2,nameAbove)

  • Is It Safe to Cast Away volatile?

    - by Yan Cheng CHEOK
    Most of the time, I am doing this way. class a { public: ~ a() { i = 100; // OK delete (int *)j; // Compiler happy. But, is it safe? // Error : delete j; } private: volatile int i; volatile int *j; }; int main() { a aa; } However, I saw an article here: https://www.securecoding.cert.org/confluence/display/seccode/EXP32-C.+Do+not+access+a+volatile+object+through+a+non-volatile+reference Casting away volatile allows access to an object through a non-volatile reference. This can result in undefined and perhaps unintended program behavior. So, what will be the workaround for my above code example?

  • How can I clear the Android app cache?

    - by Srao
    I am writing a app which can programatically clear application cache of all the third party apps installed on the device. Following is the code snippet for Android 2.2 public static void trimCache(Context myAppctx) { Context context = myAppctx.createPackageContext("com.thirdparty.game", Context.CONTEXT_INCLUDE_CO|Context.CONTEXT_IGNORE_SECURITY); File cachDir = context.getCacheDir(); Log.v("Trim", "dir " + cachDir.getPath()); if (cachDir!= null && cachDir.isDirectory()) { Log.v("Trim", "can read " + cachDir.canRead()); String[] fileNames = cachDir.list(); //Iterate for the fileName and delete } } My manifest has following permissions: android.permission.CLEAR_APP_CACHE android.permission.DELETE_CACHE_FILES Now the problem is that the name of the cache directory is printed but the list of files cachDir.list() always returns null. I am not able to delete the cache directory since the file list is always null. Is there any other way to clear the application cache?

  • appending text to all files that starts with a string

    - by learner135
    How do I append a string to all the files in a directory that starts with a particular string? I tried, cat mysig >> F* But instead of appending contents of mysig to all files starting with F, it creates a file named "F*". Obviously wildcard doesn't seem to work. Any alternatives? Thanks in advance. Edit: Also how do I delete this newly created file "F*" safely?. Using rm F* would delete all the files starting with F which I wouldn't want.

  • iPhone application build fails with "dyld: Library not loaded: /System/[...]" error? Why?

    - by Andrew J. Brehm
    For my own reasons and not for the app store I am referencing the Apple private framework Apple80211 in an iPhone app. I got the framework from an earlier version of the iPhone SDK. I added the "existing framework", verified that that absolute path to the framework is /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk/System/Library/PrivateFrameworks/Apple80211.framework and tried to build the app. But the build (to device) fails with the error dyld: Library not loaded: /System/Library/PrivateFrameworks/Apple80211.framework/Apple80211 Referenced from: /var/mobile/Applications/3691587D-87AF-44EA-A505-F73D17F39B3B/iWire2.app/iWire2 Reason: image not found I cannot figure out why Xcode would look for the library in a /System path (instead of using the path given in the frameworks list) or how to change that behaviour. I tried the tricks I found here and elsewhere for similar (and identical) sitiations: Delete the myusername.* files in the xcodeproj bundle Delete the build directory Clean all targets Start new project Result is always the same. How can I add this (or a) framework to an iPhone project AND get Xcode to at least look at the library located where I point to rather than a location in /System?

  • User oriented regex library for java

    Hello, I'm looking for a library that could perform "easy" pattern matching, a kind of pattern that can be exposed via GUI to users. It should define a simple matching syntax like * matches any char and alike. In other words, I want to do glob (globbing) like sun's implemented logic http://openjdk.java.net/projects/nio/javadoc/java/nio/file/PathMatcher.html but without relation to the file system. Ideas?

  • MySQL - Find entries that refer to a specified index.

    - by Conor H
    Hi, So I have a booking system where I have a 'lesson_type' table with 'lesson_type_id' as PK. I have a constraint in place here so I can't delete a lesson_type if there are bookings made for that lesson_type. I would like to be able to determine if this lesson_type_id is being referred to by any entries in the bookings table (or any other table for that matter) so I can notify the user gracefully. i.e. not have a mysql error be thrown when they try and delete a record. What kind of query would I use for this? Thanks.

  • MySQL Query still executing after a day..?

    - by Matt Jarvis
    Hi - I'm trying to isolate duplicates in a 500MB database and have tried two ways to do it. One creating a new table and grouping: CREATE TABLE test_table as SELECT * FROM items WHERE 1 GROUP BY title; But it's been running for an hour and in MySQL Admin it says the status is Locked. The other way I tried was to delete duplicates with this: DELETE bad_rows.* from items as bad_rows inner join ( select post_title, MIN(id) as min_id from items group by title having count(*) 1 ) as good_rows on good_rows.post_title = bad_rows.post_title; ..and this has been running for 24hours now, Admin telling me it's Sending data... Do you think either or these queries are actually still running? How can I find out if it's hung? (with Apple OS X 10.5.7)

    I am trying to get a Redmine plugin designed for Rails 2 to work with Rails 3. https://github.com/dalyons/redmine-todos-scrum-plugin I've pretty much fixed most parts, but having no success whatsoever in getting the routes to work. The original routes for Rails 2 are as follows: map.resources :todos, :name_prefix => 'project_', :path_prefix => '/projects/:project_id', :member => {:toggle_complete => :post }, :collection => {:sort => :post} map.resources :todos, :name_prefix => 'user_', :path_prefix => '/users/:user_id', :controller => :mytodos, :member => {:toggle_complete => :post }, :collection => {:sort => :post} map.my_todos 'my/todos', :controller => :mytodos, :action => :index map.connect 'projects/:project_id/todos/show/:id', :controller => "todos", :action => "show" rake routes outputs the following: sort_project_todos POST /projects/:project_id/todos/sort(.:format) {:controller=>"todos", :action=>"sort"} project_todos GET /projects/:project_id/todos(.:format) {:controller=>"todos", :action=>"index"} POST /projects/:project_id/todos(.:format) {:controller=>"todos", :action=>"create"} new_project_todo GET /projects/:project_id/todos/new(.:format) {:controller=>"todos", :action=>"new"} toggle_complete_project_todo POST /projects/:project_id/todos/:id/toggle_complete(.:format) {:controller=>"todos", :action=>"toggle_complete"} edit_project_todo GET /projects/:project_id/todos/:id/edit(.:format) {:controller=>"todos", :action=>"edit"} project_todo GET /projects/:project_id/todos/:id(.:format) {:controller=>"todos", :action=>"show"} PUT /projects/:project_id/todos/:id(.:format) {:controller=>"todos", :action=>"update"} DELETE /projects/:project_id/todos/:id(.:format) {:controller=>"todos", :action=>"destroy"} sort_user_todos POST /users/:user_id/todos/sort(.:format) {:controller=>"mytodos", :action=>"sort"} user_todos GET /users/:user_id/todos(.:format) {:controller=>"mytodos", :action=>"index"} POST /users/:user_id/todos(.:format) {:controller=>"mytodos", :action=>"create"} new_user_todo GET /users/:user_id/todos/new(.:format) {:controller=>"mytodos", :action=>"new"} toggle_complete_user_todo POST /users/:user_id/todos/:id/toggle_complete(.:format) {:controller=>"mytodos", :action=>"toggle_complete"} edit_user_todo GET /users/:user_id/todos/:id/edit(.:format) {:controller=>"mytodos", :action=>"edit"} user_todo GET /users/:user_id/todos/:id(.:format) {:controller=>"mytodos", :action=>"show"} PUT /users/:user_id/todos/:id(.:format) {:controller=>"mytodos", :action=>"update"} DELETE /users/:user_id/todos/:id(.:format) {:controller=>"mytodos", :action=>"destroy"} my_todos /my/todos {:controller=>"mytodos", :action=>"index"} /projects/:project_id/todos/show/:id {:controller=>"todos", :action=>"show"} The nearest I have got for Rails 3 is follows: scope '/projects/:project_id', :name_prefix => 'project_' do resources :todos, :controller => 'todos' do member do post :toggle_complete end collection do post :sort end end end scope '/users/:user_id', :name_prefix => 'user_' do resources :todos, :controller => 'mytodos' do member do post :toggle_complete end collection do post :sort end end end match 'my/todos' => 'mytodos#index', :as => :my_todos match 'projects/:project_id/todos/show/:id' => 'todos#show' rake routes outputs the following: toggle_complete_todo POST /projects/:project_id/todos/:id/toggle_complete(.:format) todos#toggle_complete {:name_prefix=>"project_"} sort_todos POST /projects/:project_id/todos/sort(.:format) todos#sort {:name_prefix=>"project_"} todos GET /projects/:project_id/todos(.:format) todos#index {:name_prefix=>"project_"} POST /projects/:project_id/todos(.:format) todos#create {:name_prefix=>"project_"} new_todo GET /projects/:project_id/todos/new(.:format) todos#new {:name_prefix=>"project_"} edit_todo GET /projects/:project_id/todos/:id/edit(.:format) todos#edit {:name_prefix=>"project_"} todo GET /projects/:project_id/todos/:id(.:format) todos#show {:name_prefix=>"project_"} PUT /projects/:project_id/todos/:id(.:format) todos#update {:name_prefix=>"project_"} DELETE /projects/:project_id/todos/:id(.:format) todos#destroy {:name_prefix=>"project_"} POST /users/:user_id/todos/:id/toggle_complete(.:format) mytodos#toggle_complete {:name_prefix=>"user_"} POST /users/:user_id/todos/sort(.:format) mytodos#sort {:name_prefix=>"user_"} GET /users/:user_id/todos(.:format) mytodos#index {:name_prefix=>"user_"} POST /users/:user_id/todos(.:format) mytodos#create {:name_prefix=>"user_"} GET /users/:user_id/todos/new(.:format) mytodos#new {:name_prefix=>"user_"} GET /users/:user_id/todos/:id/edit(.:format) mytodos#edit {:name_prefix=>"user_"} GET /users/:user_id/todos/:id(.:format) mytodos#show {:name_prefix=>"user_"} PUT /users/:user_id/todos/:id(.:format) mytodos#update {:name_prefix=>"user_"} DELETE /users/:user_id/todos/:id(.:format) mytodos#destroy {:name_prefix=>"user_"} my_todos /my/todos(.:format) mytodos#index /projects/:project_id/todos/show/:id(.:format) todos#show I am guessing that I am not using :name_prefix correctly, resulting in duplicate paths which are then omitted. Any help would be greatly appreciated.

  • How does C++ free the memory when a constructor throws an exception and a custom new is used

    - by Joshua
    I see the following constructs: new X will free the memory if X constructor throws. operator new() can be overloaded. The canonical definition of an operator new overload is void *operator new(heap h) and the corrisponding operator delete. The most common operator new overload is pacement new, which is void *operator new(void *p) { return p; } You almost always cannot call delete on the pointer given to placement new. This leads to a single question. How is memory cleaned up when X constructor throws and an overloaded new is used?
