  • Storing entity in XML, using MVVM to read/write in WPF Application

    - by Christian
    Say I've a class (model) called Instance with Properties DatbaseHostname, AccessManagerHostname, DatabaseUsername and DatabasePassword public class Instance { private string _DatabaseHostname; public string DatabaseHostname { get { return _DatabaseHostname; } set { _DatabaseHostname = value; } } private string _AccessManagerHostname; public string AccessManagerHostname { get { return _AccessManagerHostname; } set { _AccessManagerHostname = value; } } private string _DatabaseUsername; public string DatabaseUsername { get { return _DatabaseUsername; } set { _DatabaseUsername = value; } } private string _DatabasePassword; public string DatabasePassword { get { return _DatabasePassword; } set { _DatabasePassword = value; } } } I'm looking for a sample code to read/write this Model to XML (preferably linq2XML) = storing 1:n instances in XML. i can manage the the view and ViewModel part myself, although it would be nice if someone had a sample of that part too..

  • How does Entity Framework 4.0 determine which parameters are required for the factory method of an e

    - by Scott Davies
    Hi, I am working with Entity Framework 4.0 (VS 2010 Beta 2, NOT RC). I can model the EDM and produce the required database. When I ask VS to generate the code for the model, it generates the expected .designer.cs file. When I look at the factory methods for each entity that the designer has generated, I've noticed that it doesn't include all of the properties of the entity. Is it correct to say that the factory method only includes properties that cannot be null ? This appears to be the case, but I'm not entirely sure. Thanks, Scott

  • LINQ InsertOnSubmit Required Fields needed for debugging

    - by Derek Hunziker
    Hi All, I've been using the ADO.NET Strogly-Typed DataSet model for about 2 years now for handling CRUD and stored procedure executions. This past year I built my first MVC app and I really enjoyed the ease and flexibility of LINQ. Perhaps the biggest selling point for me was that with LINQ I didn't have to create "Insert" stored procedures that would return the SCOPE_IDENTITY anymore (The auto-generated insert statements in the DataSet model were not capable of this without modification). Currently, I'm using LINQ with ASP.NET 3.5 WebForms. My inserts are looking like this: ProductsDataContext dc = new ProductsDataContext(); product p = new product { Title = "New Product", Price = 59.99, Archived = false }; dc.products.InsertOnSubmit(p); dc.SubmitChanges(); int productId = p.Id; So, this product example is pretty basic, right, and in the future, I'll probably be adding more fields to the database such as "InStock", "Quantity", etc... The way I understand it, I will need to add those fields to the database table and then delete and re-add the tables to the LINQ to SQL Class design view in order to refresh the DataContext. Does that sound right? The problem is that any new fields that are non-null are NOT caught by the ASP.NET build processes. For example, if I added a non-null field of "Quantity" to the database, the code above would still build. In the DataSet model, the stored procedure method would accept a certain amount of parameters and would warn me that my Insert would fail if I didn't include a quantity value. The same goes for LINQ stored procedure methods, however, to my knowledge, LINQ doesn't offer a way to auto generate the insert statements and that means I'm back to where I started. The bottom line is if I used insert statements like the one above and I add a non-null field to my database, it would break my app in about 10-20 places and there would be no way for me to detect it. Is my only option to do a solution-side search for the keyword "products.InsertOnSubmit" and make sure the new field is getting assigned? Is there a better way? Thanks!

  • What is a good pattern for binding a collection of objects coming from WCF, in Silverlight?

    - by Krishna
    Hi there, I've got a question about a Silverlight WCF Databinding pattern: There are many examples about how to bind data using {Binding} expressions in XAML, how to make async calls to a WCF service, set the DataContext property of a element in the UI, how to use ObservableCollections and INotifyPropertyChanged, INotifyCollectionChanged and so on. Background: I'm using the MVVM pattern, and have a Silverlight ItemsControl, whose ItemsSource is set to an ObservableCollection property on my ViewModel object. My view is of course the XAML which has the {Binding}. Say the model object is called 'Metric'. My ViewModel periodically makes calls to a WCF service that returns ObservableCollection. MetricInfo is the data transfer object (DTO). My question is two-fold: Is there any way to avoid copying each property of MetricInfo to the model class - Metric? When the WCF calls completes, is there any way to make sure I sync the items which are in both my local ObservableCollection and the result of the WCF call - without having to first clear out all the items in the local collection and then add all the ones from the WCF call result? thanks, Krishna

  • Django + Postgres: How to specify sequence for a field

    - by Giovanni Di Milia
    I have this model in django: class JournalsGeneral(models.Model): jid = models.AutoField(primary_key=True) code = models.CharField("Code", max_length=50) name = models.CharField("Name", max_length=2000) url = models.URLField("Journal Web Site", max_length=2000, blank=True) online = models.BooleanField("Online?") active = models.BooleanField("Active?") class Meta: db_table = u'journals_general' verbose_name = "Journal General" ordering = ['code'] def __unicode__(self): return self.name My problem is that in the DB (Postgres) the name of the sequence connected to jid is not journals_general_jid_seq as expected by Django but it has a different name. Is there a way to specify which sequence Django has to use for an AutoField? In the documentation I read I was not able to find an answer.

  • Merge entries in CakePHP

    - by Andrea
    Let's say I have a Model, for example User, and I want to merge two instances of this Model, say merge User2 into User1. Explicitly this is what I mean: If a field is already filled in User1, it should remain the same If a field is missing in User1 but is present in User2, it should be copied If SomeModel BelongsTo User, every instance of SomeModel pointing to User2 should be modified to point to User1 Same if SomeModel HasAndBelongsToMany User If SomeModel HasMany User, and SomeModel1 Has User2 but no other instance Has User1, it should be modified so that SomeModel1 has User1 instead If SomeModel HasMany User, SomeModel1 Has User1 and SomeModel2 Has User2... well, I'm not sure here, I guess the only solution is to discard SomeModel2, since User1 can BelongTo only one SomeModel. Finally User2 should be removed. Is there a way to automate this? Maybe a Behaviour? If not, I may consider creating it, since I will need it a lot.

  • Eclipse Helios on OS X Snow Leopard crashes frequently when editing certain PHP files

    - by William
    I use Eclipse Helios (Eclipse Platform: 3.6.0.I20100608-0911, Eclipse IDE for PHP Developers: 1.3.0.20100617-0520) all the time on OS X (Snow Leopard), and it seems I only run into trouble whenever I'm editing a PHP file that's part of the WordPress blogging framework. When I move my cursor to a variable or function name, that often triggers the beach ball of death. I suspect Eclipse is trying to look up that variable/function and for some reason that causes an endless loop. Sometimes it's not just variables or functions. Just today I was trying to replace all occurrences of a quoted string. Every time I clicked "Replace All", the program would freeze immediately after the string was replaced and the text cursor was moved to the replaced position. I think the moving of the text cursor is important, because I got the same result when I searched for the string (thus moving the cursor), but NOT when I searched for a nonexistent string. I tried disabling everything in my preferences related to marked occurrences, hovering, code assistance, etc. Nothing helps. I use Eclipse for all my projects, and I find that it's only WordPress projects where this happens. Here's my eclipse.ini file: -startup ../../../plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library ../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx_1.1.0.v20100503 -product org.eclipse.epp.package.php.product --launcher.defaultAction openFile -showsplash org.eclipse.platform --launcher.XXMaxPermSize 512m --launcher.defaultAction openFile -vmargs -Dosgi.requiredJavaVersion=1.5 -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -XX:PermSize=128m -XX:MaxPermSize=128m -XX:MaxGCPauseMillis=10 -XX:MaxHeapFreeRatio=70 -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:CompileThreshold=5 -Xms128m -Xmx512m -Xss2m -Xdock:icon=../Resources/Eclipse.icns -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -framework ../../../plugins/org.eclipse.osgi.services_3.2.100.v20100503.jar I have 4GB of RAM, so I don't know if the problem is I'm underutilizing my resources.

This value will be overwritten using the values from the preferences I did some experimenting with the particular script that's giving me trouble. It's a hybrid of HTML and PHP, so Eclipse has to do both HTML and PHP validation. I wondered if the HTML validation had something to do with it, so I created a new file, copied the contents over, and messed with the doctype element. I found that if I replaced the well-formed XHTML 1.0 Strict doctype element with a generic doctype (as such: <!DOCTYPE html>), then I did not crash the program just by moving the cursor around. I set all HTML validation rules to "Ignore", but it still didn't solve my problems. For now, I'm just going to echo the doctype using PHP instead of entering it literally. That seems to prevent crashes. I notice that when I move the cursor around the document, Eclipse displays the "xpath" to my current location at the bottom of the screen. Sometimes there's a delay while it figures out my current path. Perhaps when it's validating against the Strict doctype, it has problems quickly calculating the xpath as I move the cursor around? Maybe it has a stack overflow that causes it to crash.

  • Select a subset of foreign key elements in inlineformset_factory in Django

    - by Enis Afgan
    Hello, I have a model with two foreign keys: class Model1(models.Model): model_a = models.ForeignKey(ModelA) model_b = models.ForeignKey(ModelB) value = models.IntegerField() Then, I create an inline formset class, like so: an_inline_formset = inlineformset_factory(ModelA, Model1, fk_name="model_a") and then instantiate it, like so: a_formset = an_inline_formset(request.POST, instance=model_A_object) Once this formset gets rendered in a template/page, there is ChoiceField associated with the model_b field. The problem I'm having is that the elements in the resulting drop down menu include all of the elements found in ModelB table. I need to select a subset of those based on some criteria from ModelB. At the same time, I need to keep the reference to the instance of model_A_object when instantiating inlineformset_factory and, therefore, I can't just use this example. Any suggestions?

  • Linq : problem with primary key

    - by Nickson
    I get the following error message The table/view 'TABLE1' does not have a primary key defined and no valid primary key could be inferred. This table/view has been excluded. To use the entity you will need to review your schema, add the correct keys and uncomment it when I try to add a view to an Entity Data Model. For testing, I have created a very simple view and I still get the error. below is the view definition SELECT DISTINCT TOP (100) PERCENT MIN(id) AS Expr4, MIN(EmpNo) AS Expr1, MIN(Name) AS Expr2, MIN(Category) AS Expr3 FROM dbo.MYView1 GROUP BY id does any one know of a simple work around. I have looked at this thread http://stackoverflow.com/questions/745341/can-ms-sql-views-have-primary-and-foriegn-keys but in my scenario, what is recommended is not applicable. If I could only have the view added to the Model.

  • Ruby on Rails: strange voting increment behavior

    - by Justin Meltzer
    So I have an up and a downvote button that inserts a vote with a value of 1 or -1 into the database. This works correctly. Then, I display the total vote count for that element by summing up its votes' values. However, this isn't working correctly, because the vote sum display is acting really strange: The first vote on a video doesn't seem to increment it at all. Then the second vote does. If I go from an upvote to a downvote, it increments up once, and then the next downvote is down. This is difficult to explain, but maybe you can figure out what is wrong with my code. I have this function in my Video model (the element that is voted on, it has_many video_votes): def vote_sum read_attribute(:vote_sum) || video_votes.sum(:value) end I also have this in my VideoVote model: after_create :update_vote_sum private def update_vote_sum video.update_attributes(:vote_sum => video.vote_sum + value) end What am I doing wrong?

  • Where do I subclass SC.Record?

    - by Jake
    I'm using SproutCore and going through the Todos tutorial on http://wiki.sproutcore.com/Todos+06-Building+with+Rails. SproutCore and Rails use different names for the primary key on a model (Sproutcore = 'guid', Rails = 'id'). The tutorial gives directions to Adjust Rails JSON output, but in my app that I'm planning on building, I cannot do this because sproutcore is only one of a couple interfaces used to interact with the Rails app. As an alternate option, the tutorial gives the following directions: Option 2: Set primaryKey in your Sproutcore model class You can subclass SC.Record and set the primaryKey of your sublcass to "id". Your Todo- Object then needs to extend from e.g. App.Rails.Record. App.Rails.Record = SC.Record.extend({ primaryKey : "id" // Extend your records from App.Rails.Record instead of SC.Record. }); Where should I subclass SC.Record (i.e. in what file) such that it is properly read and included?

  • Pylons 1.0 AttributeError: 'module' object has no attribute 'metadata'

  • Do Scala and Erlang use green threads?

    - by CHAPa
    I've been reading a lot about how Scala and Erlang does lightweight threads and their concurrency model (actors). However, I have my doubts. Do Scala and Erlang use an approach similar to the old thread model used by Java (green threads) ? For example, suppose that there is a machine with 2 cores, so the Scala/Erlang environment will fork one thread per processor? The other threads will be scheduled by user-space (Scala VM / Erlang VM ) environment. Is this correct? Under the hood, how does this really work?

  • Error Handling without Exceptions

    - by James
    While searching SO for approaches to error handling related to business rule validation , all I encounter are examples of structured exception handling. MSDN and many other reputable development resources are very clear that exceptions are not to be used to handle routine error cases. They are only to be used for exceptional circumstances and unexpected errors that may occur from improper use by the programmer (but not the user.) In many cases, user errors such as fields that are left blank are common, and things which our program should expect, and therefore are not exceptional and not candidates for use of exceptions. QUOTE: Remember that the use of the term exception in programming has to do with the thinking that an exception should represent an exceptional condition. Exceptional conditions, by their very nature, do not normally occur; so your code should not throw exceptions as part of its everyday operations. Do not throw exceptions to signal commonly occurring events. Consider using alternate methods to communicate to a caller the occurrence of those events and leave the exception throwing for when something truly out of the ordinary happens. For example, proper use: private void DoSomething(string requiredParameter) { if (requiredParameter == null) throw new ArgumentExpcetion("requiredParameter cannot be null"); // Remainder of method body... } Improper use: // Renames item to a name supplied by the user. Name must begin with an "F". public void RenameItem(string newName) { // Items must have names that begin with "F" if (!newName.StartsWith("F")) throw new RenameException("New name must begin with /"F/""); // Remainder of method body... } In the above case, according to best practices, it would have been better to pass the error up to the UI without involving/requiring .NET's exception handling mechanisms. Using the same example above, suppose one were to need to enforce a set of naming rules against items. What approach would be best? Having the method return a enumerated result? RenameResult.Success, RenameResult.TooShort, RenameResult.TooLong, RenameResult.InvalidCharacters, etc. Using an event in a controller class to report to the UI class? The UI calls the controller's RenameItem method, and then handles an AfterRename event that the controller raises and that has rename status as part of the event args? The controlling class directly references and calls a method from the UI class that handles the error, e.g. ReportError(string text). Something else... ? Essentially, I want to know how to perform complex validation in classes that may not be the Form class itself, and pass the errors back to the Form class for display -- but I do not want to involve exception handling where it should not be used (even though it seems much easier!) Based on responses to the question, I feel that I'll have to state the problem in terms that are more concrete: UI = User Interface, BLL = Business Logic Layer (in this case, just a different class) User enters value within UI. UI reports value to BLL. BLL performs routine validation of the value. BLL discovers rule violation. BLL returns rule violation to UI. UI recieves return from BLL and reports error to user. Since it is routine for a user to enter invalid values, exceptions should not be used. What is the right way to do this without exceptions?

  • Multiple .obj Models in THREE.js and detecting clicked objects

    - by ZedBee
    I have been following along this example to load .obj Model using three.js. Since I needed more than one model to load so I tried this loader.addEventListener( 'load', function ( event ) { var object = event.content; object.position.y = - 80; scene.add( object ); }); loader.load( 'obj/model1.obj' ); loader.load( 'obj/model2.obj' ); First: I don't know whether this is the right approach or not since I searched but didn't find any tutorial loading more than one .obj models. Second: I want to be able to click different models on the screen. I tried this which doest not seem to work for me. Any suggestions on this?

  • Datamodel for a MVC learning project

    - by Dofs
    Hi, I am trying to learn Microsoft MVC 2, and have in that case found a small project I wanted to deploy it on. My idea was to simulate a restaurant where you can order a table. Basics: A user can only reserve a full table, so I don't have the trouble of merging people on different tables. A person can order a table for a certain amount of hours. My question was how I could make the data model the smartest way. I thought of just having a my database like this: Table { Id, TableName } Reservations { Id TableId ReservedFrom ReservedTo UserId } User { UserId UserName ... } By doing it this way I would have to program a lot of the logic in e.g. the business layer, to support which tables are occupied at what time, instead of having the data model handle it. Therefore do you guys have a better way to do this?

  • Multi choice form field in Django

    - by Dingo
    Hi! I'am developing application on app-engine-path. I would like to make form with multichoice (acceptably languages for user). Code look like this: Language settings: settings.LANGUAGES = ((u"cs", u"Ceština"), (u"en", u"English")) Form model: class UserForm(forms.ModelForm): first_name = forms.CharField(max_length=100) last_name = forms.CharField(max_length=100) languages = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, choices=settings.LANGUAGES) The form is rendered o.k. (all languages have checkbox. IDs, NAMEs is ok.) But if I save some languages for user, those languages don't check checkboxes. User model look like this class User(User): #... languages = db.StringListProperty() #... and view: def edit_profile(request): user = request.user if request.method == 'POST': form = UserForm(request.POST) if form.is_valid(): # ... else: form = UserForm(instance=user) data = {"user":user, "form": form} return render_to_response(request, 'user_profile/user_profile.html', data)

  • ValueError with multi-table inheritance in Django Admin

    - by jorde
    I created two new classes which inherit model Entry: class Entry(models.Model): LANGUAGE_CHOICES = settings.LANGUAGES language = models.CharField(max_length=2, verbose_name=_('Comment language'), choices=LANGUAGE_CHOICES) user = models.ForeignKey(User) country = models.ForeignKey(Country, null=True, blank=True) created = models.DateTimeField(auto_now=True) class Comment(Entry): comment = models.CharField(max_length=2000, blank=True, verbose_name=_('Comment in English')) class Discount(Entry): discount = models.CharField(max_length=2000, blank=True, verbose_name=_('Comment in English')) coupon = models.CharField(max_length=2000, blank=True, verbose_name=_('Coupon code if needed')) After adding these new models to admin via admin.site.register I'm getting ValueError when trying to create a comment or a discount via admin. Adding entries works fine. Error msg: ValueError at /admin/reviews/discount/add/ Cannot assign "''": "Discount.discount" must be a "Discount" instance. Request Method: GET Request URL: http://127.0.0.1:8000/admin/reviews/discount/add/ Exception Type: ValueError Exception Value: Cannot assign "''": "Discount.discount" must be a "Discount" instance.
