  • Alternatives to RPX?

    - by keruilin
    I'm looking into integrating with some external APIs that will improve website sign-in experience. RPX seems to be highly functional. The one issue that I have with it is that you can't link accounts unless you purchase the premium. With that said... Are there currently any viable alternatives to RPX? Strengths/weaknesses?

  • 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!

  • Zend Server experiences

    - by Luke
    The other day I was looking into Zend Server and I was wondering why I would use this? OK, they say it's all tested and mission critical and Enterprise ready etc. But to me that's just the marketing department talking. Is anyone out there using this product and if so can you share your experiences with it and maybe you could also elaborate on the reason on why you choose this product for your application(s). Did you find any real benefits to using Zend server?

  • How do you unit test a unit test?

    - by FlySwat
    I was watching Rob Connerys webcasts on the MVCStoreFront App, and I noticed he was unit testing even the most mundane things, things like: public Decimal DiscountPrice { get { return this.Price - this.Discount; } } Would have a test like: [TestMethod] public void Test_DiscountPrice { Product p = new Product(); p.Price = 100; p.Discount = 20; Assert.IsEqual(p.DiscountPrice,80); } While, I am all for unit testing, I sometimes wonder if this form of test first development is really beneficial, for example, in a real process, you have 3-4 layers above your code (Business Request, Requirements Document, Architecture Document), where the actual defined business rule (Discount Price is Price - Discount) could be misdefined. If that's the situation, your unit test means nothing to you. Additionally, your unit test is another point of failure: [TestMethod] public void Test_DiscountPrice { Product p = new Product(); p.Price = 100; p.Discount = 20; Assert.IsEqual(p.DiscountPrice,90); } Now the test is flawed. Obviously in a simple test, it's no big deal, but say we were testing a complicated business rule. What do we gain here? Fast forward two years into the application's life, when maintenance developers are maintaining it. Now the business changes its rule, and the test breaks again, some rookie developer then fixes the test incorrectly...we now have another point of failure. All I see is more possible points of failure, with no real beneficial return, if the discount price is wrong, the test team will still find the issue, how did unit testing save any work? What am I missing here? Please teach me to love TDD, as I'm having a hard time accepting it as useful so far. I want too, because I want to stay progressive, but it just doesn't make sense to me. EDIT: A couple people keep mentioned that testing helps enforce the spec. It has been my experience that the spec has been wrong as well, more often than not, but maybe I'm doomed to work in an organization where the specs are written by people who shouldn't be writing specs.

    I have a object (product), with a property of type 'array' e.g. product.tags = {"tag1","tag2","tag9"} I have an array of input tags to filter on. ... but this is not quite working: List<string> filterTags = new List<string>() { "tag1", "tag3" }; var matches = from p in products where p.Tags.Contains(filterTags) select p; Any recommendations? Thanks.

  • Information on Rojiani's Numerical methods C textbook

    - by yCalleecharan
    Hi, having taken a look at a few textbooks that discuss numerical methods and C programming, I was gladly surprised when browsing through "programming in C with numerical methods for engineers" by Rojiani. I understand of course it's important that one need to have a solid background in numerical methods prior to try implementing them on a computer. I would like to know if someone here has been using this book and if possible point out strengths and weaknesses of this textbook. Thanks a lot...

  • Multilanguage website sitemap

    - by Alex
    My site is i18n based on the following structure: mydomain.com/en mydomain.com/en/product/blue-widgets mydomain.com/fr mydomain.com/fr/product/blue-widgets The site is internationalised not localised, therefore i don't want to GEO target specific locals just target "french" or "english" speaking users. When submitting a sitemap to the search engines should i send one sitemap with links to all the different language versions or have one separate sitemap for each language. Is that even possible?

  • How can I show a "selection highlighting"-rectangle around a column of a Silverlight Grid?

    - by carlmon
    I have a feature matrix implemented with Silverlight's Grid where users need to select a product. How can I indicate selection with a rectangle around the whole selected column? It is easy to put a CheckBox at the bottom of each product's column, but that is too dull. I would have preffered to use SL Toolkit's DataGrid (with built-in row selection), but it cannot be orientated vertically for a feature matrix... Thanks, Carl

  • Applying Domain Model on top of Linq2Sql entities

    - by Thomas
    I am trying to practice the model first approach and I am putting together a domain model. My requirement is pretty simple: UserSession can have multiple ShoppingCartItems. I should start off by saying that I am going to apply the domain model interfaces to Linq2Sql generated entities (using partial classes). My requirement translates into three database tables (UserSession, Product, ShoppingCartItem where ProductId and UserSessionId are foreign keys in the ShoppingCartItem table). Linq2Sql generates these entities for me. I know I shouldn't even be dealing with the database at this point but I think it is important to mention. The aggregate root is UserSession as a ShoppingCartItem can not exist without a UserSession but I am unclear on the rest. What about Product? It is defiently an entity but should it be associated to ShoppingCartItem? Here are a few suggestion (they might all be incorrect implementations): public interface IUserSession { public Guid Id { get; set; } public IList<IShoppingCartItem> ShoppingCartItems{ get; set; } } public interface IShoppingCartItem { public Guid UserSessionId { get; set; } public int ProductId { get; set; } } Another one would be: public interface IUserSession { public Guid Id { get; set; } public IList<IShoppingCartItem> ShoppingCartItems{ get; set; } } public interface IShoppingCartItem { public Guid UserSessionId { get; set; } public IProduct Product { get; set; } } A third one is: public interface IUserSession { public Guid Id { get; set; } public IList<IShoppingCartItemColletion> ShoppingCartItems{ get; set; } } public interface IShoppingCartItemColletion { public IUserSession UserSession { get; set; } public IProduct Product { get; set; } } public interface IProduct { public int ProductId { get; set; } } I have a feeling my mind is too tightly coupled with database models and tables which is making this hard to grasp. Anyone care to decouple?

  • Trying to manually recreate a simple generate/scaffolding script

    - by montooner
    I'm trying to understand Rails from the ground up. I want to learn how to manually create basic show-all/show-single/CRUD functionality in the framework. I currently am working on the display-all functionality, but am stopped by an error when I try to request all items in the Products db Here are the steps I've taken so far: script/generate controller Products script/generate model Products rake db:migrate modified products_controller.rb to add: def index() { @products = Product.all} (error: uninitialized constant ProductsController::Product) ideally, dump all orders in the view What's the fix?

  • Evaluating points in time by months, but without referencing years in Rails

    - by MikeH
    FYI, There is some overlap in the initial description of this question with a question I asked yesterday, but the question is different. My app has users who have seasonal products. When a user selects a product, we allow him to also select the product's season. We accomplish this by letting him select a start date and an end date for each product. We're using date_select to generate two sets of drop-downs: one for the start date and one for the end date. Including years doesn't make sense for our model. So we're using the option: discard_year => true When you use discard_year => true, Rails sets a year in the database, it just doesn't appear in the views. Rails sets all the years to either 0001 or 0002 in our app. Yes, we could make it 2009 and 2010 or any other pair. But the point is that we want the months and days to function independent of a particular year. If we used 2009 and 2010, then those dates would be wrong next year because we don't expect these records to be updated every year. My problem is that we need to dynamically evaluate the availability of products based on their relationship to the current month. For example, assume it's March 15. Regardless of the year, I need a method that can tell me that a product available from October to January is not available right now. If we were using actual years, this would be pretty easy. For example, in the products model, I can do this: def is_available? (season_start.past? && season_end.future?) end I can also evaluate a start_date and an end_date against current_date However, in setup I've described above where we have arbitrary years that only make sense relative to each other, these methods don't work. For example, is_available? would return false for all my products because their end date is in the year 0001 or 0002. What I need is a method just like the ones I used as examples above, except that they evaluate against current_month instead of current_date, and past? and future months instead of years. I have no idea how to do this or whether Rails has any built in functionality that could help. I've gone through all the date and time methods/helpers in the API docs, but I'm not seeing anything equivalent to what I'm describing. Thanks.

  • Does Microsoft still sell FAST ESP?

    - by Kunal Sen
    I wanted some information about FAST ESP search engine. After failing to get any response from the email query system on Microsoft site I called their ore-sales phone number. The person there told me the only way they sell FAST ESP is as a bundled product with SharePoint. That really does not make any sense and contradicts all the PDF documents they have about FAST ESP on their site. Does anyone know who to contact at Microsoft to discuss this product?

  • add text to the choice_label of ChoiceField in Django

    The ChoiceField creates a select html element and the options show the choice_label which is the _unicode_ of each model object. How can I change the text of the choice_label without modifying _unicode_ ? I have a Product model and I want to show in the options text the product name + price + link to edit. I've searched in fields.py and widgets.py but couldn't find what needed to be changed. Thanks
