  • AutoMapper and flattening nested arrays

    - by Bryan Slatner
    I'm trying to use AutoMapper to flatten multiple levels of arrays. Consider the following source classes: class X { public string A { get; set; } public Y[] B { get; set; } } class Y { public string C { get; set; } public Z[] D { get; set; } } class Z { public string E { get; set; } public string F { get; set; } } And the following destination: class Destination { public string A { get; set; } public string C { get; set; } public string E { get; set; } public string F { get; set; } } What I'd like to be able to do is get a List from one or more X, e.g.: Mapper.Map<IEnumerable<X>, IEnumerable<Destination>>(arrayOfX); I'm unable to figure out what sort of mapping configuration to use to achieve this. MapFrom seems like the way to go for 1:1 compositions, but doesn't seem to be able to handle the array (or other enumerable) unless I use AutoMapper's destination naming convention. Any insights on how to achieve this?

  • Facebook graph api resources!

    - by kielie
    Hi guys, I am creating a little flash game for the facebook platform, but I am finding it very difficult to get any decent documentation on the graph api, so if anyone has a decent resource for a beginner to go and learn the basics, I would appreciate it very much, as I am struggling to grasp the concept. Thanx!

  • Rails model relations depending on count of nested relations

    - by Lowgain
    I am putting together a messaging system for a rails app I am working on. I am building it in a similar fashion to facebook's system, so messages are grouped into threads, etc. My related models are: MsgThread - main container of a thread Message - each message/reply in thread Recipience - ties to user to define which users should subscribe to this thread Read - determines whether or not a user has read a specific message My relationships look like class User < ActiveRecord::Base #stuff... has_many :msg_threads, :foreign_key => 'originator_id' #threads the user has started has_many :recipiences has_many :subscribed_threads, :through => :recipiences, :source => :msg_thread #threads the user is subscribed to end class MsgThread < ActiveRecord::Base has_many :messages has_many :recipiences belongs_to :originator, :class_name => "User", :foreign_key => "originator_id" end class Recipience < ActiveRecord::Base belongs_to :user belongs_to :msg_thread end class Message < ActiveRecord::Base belongs_to :msg_thread belongs_to :author, :class_name => "User", :foreign_key => "author_id" end class Read < ActiveRecord::Base belongs_to :user belongs_to :message end I'd like to create a new selector in the user sort of like: has_many :updated_threads, :through => :recipiencies, :source => :msg_thread, :conditions => {THREAD CONTAINS MESSAGES WHICH ARE UNREAD (have no 'read' models tying a user to a message)} I was thinking of either writing a long condition with multiple joins, or possibly writing giving the model an updated_threads method to return this, but I'd like to see if there is an easier way first. Any ideas? Also, if there is something fundamentally wrong with my structure for this functionality let me know! Thanks!!

  • Silverlight MEF Embedded Resources

    - by Fastidious
    I have two different Silverlight UserControls imported with MEF from two different xaps. The UserControls are simply an Image on a Canvas. Both UserControls have the image marked as 'Resource'. The images are different but their names are the same (key point). I'm not quite sure what's going on behind the scenes of the MEF import but both images seem to end up in the same AppDomain. After the composition when I stick the UserControls on a Canvas, each is an instance of the class it should be, but they both show the same image. Obviously if the image file names are unique across all xaps I import I have no problem but I don't like that solution. Is there a better one?

  • Maven String Replace of Text Web Resources

    - by Jaco van Niekerk
    I have a Maven web application with text files in src/main/webapp/textfilesdir As I understand it, during the package phase this textfilesdir directory will be copied into the target/project-1.0-SNAPSHOT directory, which is then zipped up into a target/project-1.0-SNAPSHOT.war Problem Now, I need to do a string replacement on the contents of the text files in target/project-1.0-SNAPSHOT/textfilesdir. This must then be done after the textfilesdir is copied into target/project-1.0-SNAPSHOT, but prior to the target/project-1.0-SNAPSHOT.war file being created. I believe this is all done during the package phase. How can a plugin (potentially maven-antrun-plugin), plug into the package phase to do this. The text files don't contain properties, like ${property-name} to filter on. String replacement is likely the only option. Options Modify the text files after the copy into target/project-1.0-SNAPSHOT directory, yet prior to the WAR creation. After packaging, extract the text files from WAR, modify them, and add them back into the WAR. I'm thinking there is another option here I'm missing. Thoughts anyone?

  • nested foreach in PHP problem

    - by Neuquino
    I'm having problems to iterate twice on the same array: <? $indice=0 ?> <?php foreach ($comisiones as $comision1):?> <tr> <td><?php echo ++$indice ?></td> <td><?php echo tag('select',array('name'=>'comision_'.$indice),true)?> <?php foreach ($comisiones as $comision2):?> <option value="<?php echo $comision2->getId()?>"> <?php echo $comision2->getNombre()." - ".$comision2->getDescripcion()?> </option> <?php endforeach?> </select> </td> </tr> <?php endforeach?> The above code prints: And I'm expecting to see something like this (labels of the combos in the images are not the same, but I think the idea is clear): Thanks in advance

  • Zend Framework - applying order by on a nested query

    - by Gublooo
    Hey guys This might be a very simple thing. Check out the normal sql query below (select * from shopping order by shopping_id desc limit 5) order by RAND() This query runs successfully in mysql - not sure if this is the right way of doing it - but it works. It gets the last 5 ids from shopping table and randomly orders them everytime I want to achieve this in Zend. I'm not sure how to execute the first part and then apply the RAND clause to the results - what I have below does not do that. $select = $this-select() -from(array('sh'='shopping')) -order('shopping_id desc') -limit(5) -order('RAND()');

  • compareTo and nested Enums

    - by echox
    Hi, in "A Programmers Guide to Java SCJP Certification" I found an example which I can't follow. This the given enum: enum Scale3 { GOOD(Grade.C), BETTER(Grade.B), BEST(Grade.A); enum Grade {A, B, C} private Grade grade; Scale3(Grade grade) { this.grade = grade; } public Grade getGrade() { return grade; } } This is the given expression: Scale3.GOOD.getGrade().compareTo(Scale3.Grade.A) > 0; I don't understand why this expression will be true? The return value will be 2. compareTo() will return a value 0 if the given object is "less" than the object. Scale3.Grade.A is the "biggest" element of Grades, its ordinal number is 0. Scale3.GOOD is the "biggest" element of Scale3, its ordinal number is also 0. The constructor of Scale3 is called with Scale3.Grade.C, which ordinal number is 2. So the given expression is equal to the following code: Scale3.Grade.C.compareTo(Scale3.Grade.A) > 0; A is "bigger" than C, so shouldn't be the result < 0?

  • Resources for widget creation

    - by Kenji Crosland
    My rails app is about to go live and I'm trying to figure out how to create a widget based on data on the site. My Javascript is not too hot--limited to the O'reilly head first book on JS. I can read simple Javascript okay but when it comes to writing it I'm a little lost. That said, I hope to roll out a widget, maybe a wordpress plugin too soon after my app is launched. Does anyone know of any rails plugins, javascript templates, tutorials or books that can get me going? I did ask a similar question before here: But my limited knowledge of JS kept me from implementing the suggested answer properly.

  • How to extract nested tar.gz files easily?

    - by StarCub
    Hi, I need to extract tar.gz a file. It's about 950mb. It has another 23 tar.gz files in it. Each of those 23 tar.gz files has one tar file in them. My questions is how I can easily extract all of them? Is there a commandline tool that I can use? The structure is like the following: foo.tar.gz +---bar1.tar.gz ¦ +---foobar1.tar +---bar2.tar.gz ¦ +---foobar2.tar +---bar3.tar.gz ¦ +---foobar3.tar +---bar4.tar.gz ¦ +---foobar4.tar +---bar5.tar.gz ¦ +---foobar5.tar +---bar6.tar.gz ¦ +---foobar6.tar | .......... | .......... | .......... | 23 of them Thanks in advance.

  • Resources for getting started with Lucene.Net?

    - by Matt Dotson
    I'm building a simple site that allows users to post text content and I want to add it to a search index as it gets posted, so my site search is up to date. From what I can tell Lucene.NET is a good full text search framework. I've found very few examples of how to use it though. Can anyone post some good references for learning about Lucene?

  • Sorting nested hash in ruby

    - by Rabbott
    Provided the following ruby hash: { cat: { 1: 2, 2: 10, 3: 11, 4: 1 }, wings: { 1: 3, 2: 5, 3: 7, 4: 7 }, grimace: { 1: 4, 2: 5, 3: 5, 4: 1 }, stubborn: { 1: 5, 2: 3, 3: 7, 4: 5 } } How can I sort the hash by the sum of 'leaf' excluding "4", for instance the value to compare for "cat" would be (2 + 10 + 11) = 23, the value for "wings" would be (3 + 5 + 7) = 15 so if I was comparing just those two they would be in the correct order, highest sum on top. It is safe to assume that it will ALWAYS be {1: value, 2: value, 3: value, 4: value} as those are keys for constants I have defined. It is also safe to assume that I will only ever want to exclude the key "4", and always use the keys "1", "2", and "3"

  • Return nested alias for linq expression

    - by Schotime
    I have the following Linq Expression var tooDeep = shoppers .Where(x => x.Cart.CartSuppliers.First().Name == "Supplier1") .ToList(); I need to turn the name part into the following string. x.Cart.CartSuppliers.Name As part of this I turned the Expression into a string and then split on the . and removed the First() argument. However, when I get to CartSuppliers this returns a Suppliers[] array. Is there a way to get the single type from this. eg. I need to get a Supplier back. Thanks

  • Getting text values of li (even nested) in JQuery

    - by Tahir Akram
    Hi; <ul> <li class="item-i">AI</li> <li class="item-ii">AII <ul class="level-2"> <li class="item-a">A</li> <li class="item-b">B</li> <li class="item-c">C</li> </ul> </li> <li class="item-iii">III</li> </ul> How can I get values AI AII A B C III? What I tried so far is following: $(document).ready(function() { $('li').each(function(index) { alert($(this).text()); }); }); But it does not gave me required results. When it reaches "item-ii" it gave all result. I want item one by one.

  • Maven copy project output into other project resources

    - by Thomas
    There are two projects: 1) applet project that outputs jar file 2) web app project that should host the jar file. After (1) finished building, the applet jar file should be copied into the webapp folder of (2). The purpose is that (2) will host the applet (1) on the Internet. A lot of examples explain how to use another project as a library dependency. Other examples, show how to use ant plugin to copy files. I am unsure on how to properly set this up, so that 'mvn install' on the parent project will do the copying at the right time.

  • UICollectionViewController nested in a normal UIViewController

    - by patrickS
    I have added a UICollectionView into a normal ViewController (MainViewController), and than created a UICollectionViewController Subclass (CollectionViewController) in the ViewController and connected the UICollectionView outlet with the CollectionViewController object _collectionViewController = [[CollectionViewController alloc] initWithCollectionViewLayout:_collectionView.collectionViewLayout]; _collectionView.dataSource = _collectionViewController; _collectionView.delegate = _collectionViewController; In the CollectionViewController I have setup an simple NSArray object and I show this one. This works as expected. But If I try to access the collectionview from the CollectionViewController via self.collectionview I am not able to access this one. I dont know what I have to do, to also connect the collectionview. I have build a sample ios-app it is available at: https://github.com/patricks/uicollectionview-problem The method - (void)outputSelectedCell in the UICollectionViewController always shows, that there is nothing selected… I hope you understand the problem.

  • Load WPF styles (static resources) from an external assembly

    - by Shimmy
    I have a few WPF applications and I want all my styles to be in a shared assembly instead of declaring them in each application separately. I am looking for a way so I don't have to change all my Style="{StaticResource BlahBlah}" in the existing applications; I just want to add the reference to this style assembly, and delete it from the current application, so it's taken from the assembly. Is there any way?

  • Nested asynchronous calls do not seem to execute as expected

    - by Kristof Van Landschoot
    While trying out jQuery, I have a question that is probably a newbie mistake, but I cannot seem to find the solution. This is the code: $.get("index.html", function() { var i = 0; for (; i < 3; i++) { var lDiv = document.createElement('div'); lDiv.id = 'body-' + i; document.getElementById('body').appendChild(lDiv); $.get('index.html', function(data) { lDiv.innerHTML = "<p>Hello World " + i + "</p>"; }); } }); The output seems to be <div id='body-0'></div> <div id='body-1'></div> <div id='body-2'> <p>Hello World 3</p> </div> I expected the lDiv.innerHTML= code to be executed for each i, but apparently it is only executed for the last i? What am I overlooking?
