  • Adding multiple data importers support to web applications

    - by DigiMortal
    I’m building web application for customer and there is requirement that users must be able to import data in different formats. Today we will support XLSX and ODF as import formats and some other formats are waiting. I wanted to be able to add new importers on the fly so I don’t have to deploy web application again when I add new importer or change some existing one. In this posting I will show you how to build generic importers support to your web application. Importer interface All importers we use must have something in common so we can easily detect them. To keep things simple I will use interface here. public interface IMyImporter {     string[] SupportedFileExtensions { get; }     ImportResult Import(Stream fileStream, string fileExtension); } Our interface has the following members: SupportedFileExtensions – string array of file extensions that importer supports. This property helps us find out what import formats are available and which importer to use with given format. Import – method that does the actual importing work. Besides file we give in as stream we also give file extension so importer can decide how to handle the file. It is enough to get started. When building real importers I am sure you will switch over to abstract base class. Importer class Here is sample importer that imports data from Excel and Word documents. Importer class with no implementation details looks like this: public class MyOpenXmlImporter : IMyImporter {     public string[] SupportedFileExtensions     {         get { return new[] { "xlsx", "docx" }; }     }     public ImportResult Import(Stream fileStream, string extension)     {         // ...     } } Finding supported import formats in web application Now we have importers created and it’s time to add them to web application. Usually we have one page or ASP.NET MVC controller where we need importers. To this page or controller we add the following method that uses reflection to find all classes that implement our IMyImporter interface. private static string[] GetImporterFileExtensions() {     var types = from a in AppDomain.CurrentDomain.GetAssemblies()                 from t in a.GetTypes()                 where t.GetInterfaces().Contains(typeof(IMyImporter))                 select t;       var extensions = new Collection<string>();     foreach (var type in types)     {         var instance = (IMyImporter)type.InvokeMember(null,                        BindingFlags.CreateInstance, null, null, null);           foreach (var extension in instance.SupportedFileExtensions)         {             if (extensions.Contains(extension))                 continue;               extensions.Add(extension);         }     }       return extensions.ToArray(); } This code doesn’t look nice and is far from optimal but it works for us now. It is possible to improve performance of web application if we cache extensions and their corresponding types to some static dictionary. We have to fill it only once because our application is restarted when something changes in bin folder. Finding importer by extension When user uploads file we need to detect the extension of file and find the importer that supports given extension. We add another method to our page or controller that uses reflection to return us importer instance or null if extension is not supported. private static IMyImporter GetImporterForExtension(string extensionToFind) {     var types = from a in AppDomain.CurrentDomain.GetAssemblies()                 from t in a.GetTypes()                 where t.GetInterfaces().Contains(typeof(IMyImporter))                 select t;     foreach (var type in types)     {         var instance = (IMyImporter)type.InvokeMember(null,                        BindingFlags.CreateInstance, null, null, null);           if (instance.SupportedFileExtensions.Contains(extensionToFind))         {             return instance;         }     }       return null; } Here is example ASP.NET MVC controller action that accepts uploaded file, finds importer that can handle file and imports data. Again, this is sample code I kept minimal to better illustrate how things work. public ActionResult Import(MyImporterModel model) {     var file = Request.Files[0];     var extension = Path.GetExtension(file.FileName).ToLower();     var importer = GetImporterForExtension(extension.Substring(1));     var result = importer.Import(file.InputStream, extension);     if (result.Errors.Count > 0)     {         foreach (var error in result.Errors)             ModelState.AddModelError("file", error);           return Import();     }     return RedirectToAction("Index"); } Conclusion That’s it. Using couple of ugly methods and one simple interface we were able to add importers support to our web application. Example code here is not perfect but it works. It is possible to cache mappings between file extensions and importer types to some static variable because changing of these mappings means that something is changed in bin folder of web application and web application is restarted in this case anyway.

  • Looking for a package allowing user-entered profiles

    - by Mark
    Title was a little hard to work, but take this as an example. User goes to site, creates account, and then has his/her own profile to edit. Let's say the profile includes height, weight, sex, eye color, etc.. I've really only used wordpress before, but I'm sure something else would cater to this better. The entire site is focused around a person having their own profile page with the info they supply. Thanks!

  • how does private sales ecommerce site work on their SEO?

    - by 142857
    In a private sales ecommerce site, users need to sign up/in before they can access the pages of website. So, even if a user tries to directly navigate to a product page, he is redirected to sign in. I am wondering then how does these sites manage their SEO, as it would imply google too can't crawl these pages, or do they completely ignore the SEO benefit of allowing google to crawl the product and catalogue pages?

  • SEO and JavaScript since Google admits JS parsing

    - by schlingel
    We're planning on building a HTML snapshot creation service to provide the Google crawlers with static HTML of our JS driven single page application. Is this still necessary and/or encouraged since Google openly admits it is parsing JS now? How should I tackle this evaluation? Are there tools to provide data on when it's needed to provide snapshots and when google has sufficent parsing? Is it better because it would be much faster in comparison to the JS incremental rendering?

  • Why the Indian link builders or SEO companies can make so many high quality links at the same time? [closed]

    - by chiba
    There are a lot of Indian SEO companies or link builders that offer a lot of high quality link. Some of them for example offer links just from "co.uk" or "French site" with high page ranks. I have heard that even the SEO companies from other countries outsource link building to India. Do they have special connections for building links ? or Do they exchange the information between another Indian companies and have a big database of the sites where they can link?

  • Avoid pagination pages from appearing higher than real content in SERPS

    - by WordPress Developer
    I have a gallery-type website that has about 20k of pages and naturally it uses pagination. However, sometimes /page/2 appears higher in search results than /post/201339 for example. I'd like to give emphasis to the actual content (posts, videos, whatever the site is about) and not on pages that merely list this content in a paginated matter. What is the best way to avoid this issue? Maybe a NOINDEX,FOLLOW meta tag on the paginated pages?

Most things look intimidating, but I'm sure I could somewhere on some problem if I actually attacked it.

  • How to configure Google sitemap links in Wordpress? (without editing its HTML or PHP source code)

    - by Alexander Farber
    I run a Wordpress 3.7.1–de_DE site, but don't have much experience with it yet. When my site comes up in a Google search, there are 2 Google sitemap links displayed underneath: One of them points to a non-existent webpage /imprint though and I had to add a page at that URL to workaround this (and I want the URL actually be /impressum anyway since the site is in German and has German URLs).

    - by euDennis
    I'm with some problems with my internet with oscillations in connection, causing some sites to get "Not Found" page sometimes. This isn't all the time, just some random times daily. My question is. There is any tool to monitor these basic information (ping, upload and download) daily to make an report and check the oscillations? Because, if someone from internet provider come at my house, probably it won't see the oscillations. Thanks, bye

  • What can I do with urllib?

    - by Aerovistae
    I grasp that it can fetch internet resources, but I'm not really fully appreciating what that means. I was doing the challenges at pythonchallenge.com, and I got past the one that requires urllib to fetch the page and read the source, but I don't see how this is useful quite yet. And examples are kind of lacking in diversity. What else can it do, or how can I use this to my advantage? (Besides building a web browser...)

  • Utility Queries–Structure of Tables with Identity Column

    I have been doing a presentation on sequences of late (last planned version of that presentation was last week, but should be able to get the gist of things from the slides and the code posted here on my presentation page), and as part of that, I started writing some queries to interrogate the structure of tables. I started with tables using an identity column for some purpose because they are considerably easier to do than sequences, specifically because the limitations of identity columns make...(read more)
