  • Groovy MetaClass - Add category methods to appropriate metaClasses

    - by noah
    I have several categories that I use in my Grails plugin. e.g., class Foo { static foo(ClassA a,Object someArg) { ... } static bar(ClassB b,Object... someArgs) { ... } } I'm looking for the best way to add these methods to the meta-classes so that I don't have to use the category classes and can just invoke them as instance methods. e.g., aInstance.foo(someArg) bInstance.bar(someArgs) Is there a Groovy/Grails class or method that will help me do this or am I stuck iterating through the methods and adding them all myself?

  • Convert string to JSON using Python

    - by Luiz Fernando
    Hi, I'm a little bit confused with JSON in Python. To me, it seems like a dictionary, and for that reason I'm trying to do that: json = """{ "glossary": { "title": "example glossary", "GlossDiv": { "title": "S", "GlossList": { "GlossEntry": { "ID": "SGML", "SortAs": "SGML", "GlossTerm": "Standard Generalized Markup Language", "Acronym": "SGML", "Abbrev": "ISO 8879:1986", "GlossDef": { "para": "A meta-markup language, used to create markup languages such as DocBook.", "GlossSeeAlso": ["GML", "XML"] }, "GlossSee": "markup" } } } } } """ But when I do print dict(json), it gives an error. How can I transform this string into a structure and then call json["title"] to obtain "example glossary"? Thanks.

  • How to select saxon TransformerFactory in Java

    - by pAkY88
    In my web application I need to use Saxon TransformerFactory to use XSLT 2.0 but I can't use setProperty method because I haven't this right on the web server and there is a Security Manager. So i have read that it's possible to do this: Use the Services API (as detailed in the JAR specification), if available, to determine the classname. The Services API will look for a classname in the file META-INF/services/javax.xml.transform.TransformerFactory in jars available to the runtime. I found this file in WEB-INF/lib/saxon9.jar but when I istantiate a TransformerFactory is always selected default factory and not saxon factory. How can I select Saxon Transformer Factory? Thanks

  • Does MS PnP Unity Scan for Assemblies Like StructureMap?

    - by rasx
    In Using StructureMap 2.5 to scan all assemblies in a folder, we can see that StructureMap uses AssembliesFromPath() to explicitly look for types to resolve. What is the equivalent of this in Microsoft Unity? Because Unity is such a generic term, searching for documents about this online is not that easy. Update: Unity has something called an Assembly Matching Rule but its description does not communicate to me that it scans folders.

  • Django model manager didn't work with related object when I do aggregated query

    - by Satoru.Logic
    Hi, all. I'm having trouble doing an aggregation query on a many-to-many related field. Let's begin with my models: class SortedTagManager(models.Manager): use_for_related_fields = True def get_query_set(self): orig_query_set = super(SortedTagManager, self).get_query_set() # FIXME `used` is wrongly counted return orig_query_set.distinct().annotate( used=models.Count('users')).order_by('-used') class Tag(models.Model): content = models.CharField(max_length=32, unique=True) creator = models.ForeignKey(User, related_name='tags_i_created') users = models.ManyToManyField(User, through='TaggedNote', related_name='tags_i_used') objects_sorted_by_used = SortedTagManager() class TaggedNote(models.Model): """Association table of both (Tag , Note) and (Tag, User)""" note = models.ForeignKey(Note) # Note is what's tagged in my app tag = models.ForeignKey(Tag) tagged_by = models.ForeignKey(User) class Meta: unique_together = (('note', 'tag'),) However, the value of the aggregated field used is only correct when the model is queried directly: for t in Tag.objects.all(): print t.used # this works correctly for t in user.tags_i_used.all(): print t.used #prints n^2 when it should give n Would you please tell me what's wrong with it? Thanks in advance.

  • Django blog reply system

    - by dana
    hello, i'm trying to build a mini reply system, based on the user's posts on a mini blog. Every post has a link named reply. if one presses reply, the reply form appears, and one edits the reply, and submits the form.The problem is that i don't know how to take the id of the post i want to reply to. In the view, if i use as a parameter one number (as an id of the blog post),it inserts the reply to the database. But how can i do it by not hardcoding? The view is: def save_reply(request): if request.method == 'POST': form = ReplyForm(request.POST) if form.is_valid(): new_obj = form.save(commit=False) new_obj.creator = request.user new_post = New(1) #it works only hardcoded new_obj.reply_to = new_post new_obj.save() return HttpResponseRedirect('.') else: form = ReplyForm() return render_to_response('replies/replies.html', { 'form': form, }, context_instance=RequestContext(request)) i have in forms.py: class ReplyForm(ModelForm): class Meta: model = Reply fields = ['reply'] and in models: class Reply(models.Model): reply_to = models.ForeignKey(New) creator = models.ForeignKey(User) reply = models.CharField(max_length=140,blank=False) objects = NewManager() mentioning that New is the micro blog class thanks

  • C#: BackgroundWorker cloning resources?

    - by Dav
    The problem I've been struggling with this partiular problem for two days now and just run out of ideas. A little... background: we have a WinForms app that needs to access a database, construct a list of related in-memory objects from that data, and then display on a DataGridView. Important point is that we first populate an app-wide cache (List), and then create a mirror of the cache local to the form on which the DGV lives (using List constructor param). Because fetching the data takes a good few seconds (DB sits on a LAN server) to load, we decided to use a BackgroundWorker, and only refresh the DGV once the data is loaded. However, it seems that doing the loading via a BGW results in some memory leak... or an error on my part. When loaded using a blocking method call, the app consumes about 30MB of RAM; with a BGW this jumps to 80MB! While it may not seem as much anyway, our clients are not too happy about it. Relevant code Form private void MyForm_Load(object sender, EventArgs e) { MyRepository.Instance.FinishedEvent += RefreshCache; } private void RefreshCache(object sender, EventArgs e) { dgvProducts.DataSource = new List<MyDataObj>(MyRepository.Products); } Repository private static List<MyDataObj> Products { get; set; } public event EventHandler ProductsLoaded; public void GetProductsSync() { List<MyDataObj> p; using (MyL2SDb db = new MyL2SDb(MyConfig.ConnectionString)) { p = db.PRODUCTS .Select(p => new MyDataObj {Id = p.ID, Description = p.DESCR}) .ToList(); } Products = p; // tell the form to refresh UI if (ProductsLoaded != null) ProductsLoaded(this, null); } public void GetProductsAsync() { using (BackgroundWorker myWorker = new BackgroundWorker()) { myWorker.DoWork += delegate { List<MyDataObj> p; using (MyL2SDb db = new MyL2SDb(MyConfig.ConnectionString)) { p = db.PRODUCTS .Select(p => new MyDataObj {Id = p.ID, Description = p.DESCR}) .ToList(); } Products = p; }; // tell the form to refresh UI when finished myWorker.RunWorkerCompleted += GetProductsCompleted; myWorker.RunWorkerAsync(); } } private void GetProductsCompleted(object sender, RunWorkerCompletedEventArgs e) { if (ProductsLoaded != null) ProductsLoaded(this, null); } End! GetProductsSync or GetProductsAsync are called on the main thread, not shown above. Could it be that the GarbageCollector just gets lost with two threads? Or is it the task manager that shows incorrect values? Will be greateful for any responses, suggestions, criticism.

  • Reasons to start a new project in COBOL

    - by luvieere
    Are there any feasible reasons to start a new project in COBOL? What benefits of this language one would find convincing enough to start a new project in it? I'm thinking more about viewing the language in terms of Behavior Driven Development, something related to the steps involved in using a framework such as Cucumber, only that behavior description and step definition would be integrated into one unit by using tha language's features.

  • Attachment_fu error

    - by cswebgrl
    Hello, I am getting an error while trying to upload images on an Ubuntu machine that's running Rails 2.3.4, Ruby 1.8.6 using attachment_fu with image science. FreeImage exception for type ???: IPTC: Invalid key 'Tag 0x025C' The error seems to point to this line in the image_science_processor in the attachment_fu plugin: def with_image(file, &block) ::ImageScience.with_image file, &block end My initial thoughts are that it has something to do with meta tags and the images and maybe free image. I don't actually see this error on my dev machine - Mac Snow Leopard, Rails 2.3.5, Ruby 1.8.7. Before I start messing versions on the production boxes, has anyone else encountered this issue and have an idea to fix it? THANKS!!!!

  • Special characters in PHP / MySQL

    - by Jonathan
    Hi, I have in the database words that include special character (in Spanish mostly, like tildes). In the database everything is saved and shown correctly with PHPmyAdmin, but when I get the data (using PHP) and display it in a browser, I get a weird character, like a "?" with a square... I need a general fix so I don't need to escape each character every time, and also I would be able to insert special Spanish characters from a PHP form into the database... The HTML is correct: <meta http-equiv="content-type" content="text/html; charset=utf-8" /> All tables and databas are set to utf8_spanish The character I get: ? Any suggestions??? Thanks!!!

  • Practical Uses of Fractals in Programming

    - by Sami
    Fractals have always been a bit of a mystery for me. What practical uses (beyond rendering to beautiful images) are there for fractals in the various programming problem domains? And please, don't just list areas that use them. I'm interested in specific algorithms and how fractals are used with those algorithms to solve something in practice. Please at least give a short description of the algorithm.

  • Embedded AXIS2: Serving a custom WSDL

    - by Maik
    I am using a console app that starts several axis instances without using a packages archive. Like this: AxisService axisService2 = AxisService.createService( new Myclass.getClass().getName(), axisConfigurationContext.getAxisConfiguration()); axisService2.addParameter(new Parameter("useOriginalwsdl", "true")); axisConfigurationContext.getAxisConfiguration().addService(axisService2); Now, I need to serve a custom WSDL. I tried adding a META-INF folder to the bin-root, and in various other places, but with no success. How do I specify in this case the location of a custom WSDL? Thanks!

  • ASP.NET CustomValidator trying to match to System.EventHandler?

    - by annakata
    I have markup so: <asp:TextBox runat="server" ID="Accountname" /> <asp:CustomValidator runat="server" ControlToValidate="Accountname" OnServerValidate="Accountname_CheckUnique" meta:resourcekey="ACCOUNTNAME_UNAVAILABLE" /> Codebehind so: protected void Accountname_CheckUnique(object source, ServerValidateEventArgs arguments) { arguments.IsValid = Foo(); } Which was working just fine, and then without changing anything on the page ASP now insists: No overload for 'Accountname_CheckUnique' matches delegate 'System.EventHandler' Well no, and nor should it according to MSDN. It's late and I'm tired, anybody know how to fix this or point out the glaring flaw in my comprehension?

  • IE8 won't load JavaScript file in "Compatibility View."

    - by Don Jones
    Here's my JS insert: <script type="text/javascript" src="include/profile.js"></script> In IE8 with "Compatibility View," the file never loads. The first line in the file is a simple alert() call, so that I know it loaded. Change the browser to Standards View, and it loads fine. Also, if I add: <meta http-equiv="X-UA-Compatible" content="IE=100" > It forces to Standards View and it loads fine. Any idea why this would be the case? I've not been able to test against IE7, but I know the JS file also does not load in IE6. Right now the tag is in the section of the file.

  • Accessing the feed/entry/id field of an ATOM 1.0 feed with the ROME library

    - by PartlyCloudy
    Hi, I feel a bit stupid asking this question, but I don't know how I can access the ID field of an entry when using ROME to parse an Atom feed. ROME provides it's own meta level of feeds/items, i.e. SyndFeed and SyndEntry. Being an abstraction over RSS and ATOM they only contain elements both formats support. Thus, there is no method to get an ID of an entry. There also exist low level packages for the distinct formats, and the Atom package contains com.sun.syndication.feed.atom.Entry, which provides getId(). However, I don't know how can I convert my SyndEntry into an Entry. I have not found a way to convert it. The (outdated) tutorials show a conversion, but that's only for output though. So how can I easily access the ID field? Thanks in advance.

  • Spring Roo from WSDL?

    - by Tom O'Brien
    Hi folks, Spring Roo + GWT is very exciting but I'd like to use an existing Web Service as a backend so I was wondering if there is any way to configure Roo to use a WSDL as the starting point rather than the entity description (and have it wire in the Jax-WS calls to the service). Thanks!

  • Automatic database schema generation and migration with Perl

    - by pistacchio
    In Ror or Django or web2py you can "describe" a database (as a set of classes that remaps to tables) and the framework (having being provided with a connection string to the desired database) generates the tables, fields, relations and in the case of RoR and web2py it also keeps it up-to-date (eg, removing a class drops the table, adding a property to the class triggers an "alter table add" etc). Is there any Perl module that does the same? Eg, it takes the YAML/XML/JSON description of a database as input and modifies/generates the database schema accordingly?
