  • Reading option values in select

    - by user281180
    I have select values as follows: <select id="SelectBox" multiple="multiple"> <% foreach (var item in Model.Name) { %> <option value="<%= item.Value %>"><%=item.Text%></option> <% } %> </select> I have a function in jquery that will have to read both the text and value. I need to have the values in array so that I can display them in a table with a column Id and another column text. My problem is that Im not able to retrieve each and every value separately. Im having the text in one line, test1test2test3. function read() { $("#SelectBox").each(function() { var value = $(this).val(); var text = $(this).text(); alert(value);alert(text); }); }

  • Custom array class with assotiated objects

    - by FancyDancy
    I have a simple structure, it's just an array of model's objects. For example, it's a users with books. @books = Book.find(:all, :include = :users) I need to check, does user have a book? I have written a helper method: def has_book?(user_id) @books.select{|b| b.user_id == user_id}.any? end Then, i need to get only books from selected library def in_library(n) @books.select{|b| b.library == n} end I have tried to make custom Array class: class BooksList < Array def initialize(books) self << books end # its my custom methods def has_book?(user_id) self.select{|b| b.user_id == user_id}.any? end def in_library(n) self.select{|b| b.library == n} end end It works, but i have only one problem. I can't access Book's assotiated object (user). So i can't write: @books = BookList.new(Book.find(:all, :include => :users)) @books.first.user.id # it says undefined method `user' for #<Array:0x104b43e08>

  • How to organize a ASP.NET MVC solution (DDD)

    - by vandalo
    Hello everyone. I am trying to start a new project (asp.net MVC) and I would like to apply some DDD rules I've learned in these last few months. I don't know how to organize my solution though. I would like to use Nhibernate but I don't want to use Fluent Nhibernate cause it must be something like an experiment. I've seen some examples where people keep everything in the same project. Some others tend to create a different project for everything. Do you think I should differentiate the model and the repository or put it in the same project? If someone has some links to articles etc it would be appreciated. thanks Alberto

  • WPF ComboBox SelectedItem - change to previous value

    - by Taylor
    Hello, I have a ComboBox that has the SelectedItem bound to the ViewModel. <ComboBox SelectedItem="{Binding SelItem, Mode=TwoWay}" ItemsSource="{Binding MyItems}"> When the user selects a new Item in the View ComboBox, I want to display a prompt and verify that they want to make the change. In the SetItem Property setter in the View Model, I display a Dialog to confirm the selection. When they say yes, it works fine. My problem is, when the user clicks on "No" I am not sure who to get the ComboBox to revert back to the previous value. The Property in the ViewModel has the correct older value, however in the View the ComboBox displays the newly Selected Value. I want the user to select an item, confirm they want to go ahead with it, and if they decide not to, I want the ComboBox to revert back to the previous item. How can I accomplish this? Thanks!

  • Alternatives to NServiceBus that doesn't use MSMQ

    - by G33kKahuna
    I think the title sums it all .... We have a .NET 2.0 system trying to implement a distributed pub/ sub model. I came across NServiceBus, RhinoBus and MassTransit. Unfortunately, these are MSMQ based. I am tasked to figure out pub/ sub alternatives that uses a different messaging alternatives ... the only reason for seeking MSMQ alternatives is to overcome the message size restriction. Since our enterprise app messages can potentially get truncated due to per message restriction... any guidance is much appreciated

  • Using Yii framework, what would be a right way to process an attribute before displaying it using CH

    - by Karolis
    Say I have this line of code in the view. <?php echo CHtml::activeTextField($model,'start_time'); ?> start_time is a UNIX timestamp. When just displaying it in a view I can apply functions like date() on it. Where should I apply the formatting when I'm displaying it in a form, by using the above line of code? (This case of timestamps/dates might be special, but I'm also interested in how would one go about if it wasn't a date and I just want to work with "value in database" < "different representations of the value in different views. Thanks =)

  • HMM for perspective estimation in document image, can't understand the algorithm

    - by maximus
    Hello! Here is a paper, it is about estimating the perspective of binary image containing text and some noise or non text objects. PDF document The algorithm uses the Hidden Markov Model: actually two conditions T - text B - backgrouond (i.e. noise) It is hard to understand the algorithm itself. The question is that I've read about Hidden Markov Models and I know that it uses probabilities that must be known. But in this algorithm I can't understand, if they use HMM, how do they get those probabilities (probability of changing the state from S1 to another state for example S2)? I didn't find anything about training there also in that paper. So, if somebody understands it, please tell me. Also is it possible to use HMM without knowing the state change probabilities?

  • django authentication .htaccess static

    - by Uszy Wieloryba
    In my app users can upload files for other users. To make the uploaded files accesible only for the addresse I need some kind of static files authentication system. My idea, is to create the apache hosted directory for each user and to limit access to this derectory using .htaccess. This means that each time new django user is created, I need to create a directory and the appropriate .htaccess file in it. I know I should do it using post_save signals on User model but I don't know how to create the .htaccess in the user's directory from python level. Can you help me with that? Or perhaps you have better solution to my problem?

  • OpenGL Color Interpolation across vertices

    - by gutsblow
    Right now, I have more than 25 vertices that form a model. I want to interpolate color linearly between the first and last vertex. The Problem is when I write the following code glColor3f(1.0,0.0,0.0); vertex3f(1.0,1.0,1.0); vertex3f(0.9,1.0,1.0); . .`<more vertices>; glColor3f(0.0,0.0,1.0); vertex3f(0.0,0.0,0.0); All the vertices except that last one are red. Now I am wondering if there is a way to interpolate color across these vertices without me having to manually interpolate color natively (like how opengl does it automatically) at each vertex since, I will be having a lot more number of colors at various vertices. Any help would be extremely appreciated. Thank you!

  • Unable to save to wincache from cakePHP shell

    - by Phillaf
    I'm trying to retrieve the weather from wunderground.com through their API, and store it in wincache. For testing purposes I made this function in the News model: public function updateWeather(){ $results = file_get_contents('http://api.wunderground.com/api/**api_key**/conditions/q/CA/Montreal.json'); $results = json_decode($results); return Cache::write('weather', $results); } It works fine when I call this from the controller. However, I can't figure why that same function doesn't work when called from the console. I made this shell in order to eventually add this to windows task scheduler. class WeatherShell extends AppShell { public $uses = array('News'); public function main() { $this->News->updateWeather(); } } When running this, I see that $results is correctly populated. I get 'true' from Cache::write(), however, I get 'false' when trying to read. What subtlety am I missing?

  • How would I best address this object type heirachy? Some kind of enum heirarchy?

    - by FerretallicA
    I'm curious as to any solutions out there for addressing object heirarchies in an ORM approach (in this instance, using Entity Framework 4). I'm working through some docs on EF4 and trying to apply it to a simple inventory tracking program. The possible types for inventory to fall into are as follows: INVENTORY ITEM TYPES: Hardware PC Desktop Server Laptop Accessory Input (keyboards, scanners etc) Output (monitors, printers etc) Storage (USB sticks, tape drives etc) Communication (network cards, routers etc) Software What recommendations are there for handling enums in a situation like this? Are enums even the solution? I don't really want to have a ridiculously normalised database for such a relatively simple experiment (eg tables for InventoryType, InventorySubtype, InventoryTypeToSubtype etc). I don't really want to over-complicate my data model with each subtype being inherited even though no additional properties or methods are included (except PC types which would ideally have associated accessories and software but that's probably out of scope here). It feels like there should be a really simple, elegant solution to this but I can't put my finger on it. Any assistance or input appreciated!

  • Implementing website messaging services

    - by Alex
    There's a website which currently has only web interfaces for all the users. However, new requirement has emerged which says that there is a need in providing an alternative interface for a certain group of website users who want to regularly receive pushed notifications(messages) that would inform them about new events(news) in their field of interest. What sort of interface would it be?Is it all about using a MOM(message-oriented middleware) like JMS and deploying it withing an application server on a website using publish/subscribe model?Is it the correct way how to meet these sort of requirements?And if it's not a web-based interface,would kind of interface would it be then for the users? Thanks

  • Bidirectional one-to-many associations with indexed collections in NHibernate

    - by Jørn Schou-Rode
    Last summer, I asked a question regarding how to add new object to an IList mapped as a one-to-many with NHibernate. One of the answers let me to this paragraph in the documentation: Please note that NHibernate does not support bidirectional one-to-many associations with an indexed collection (list, map or array) as the "many" end, you have to use a set or bag mapping. While I am pretty sure I understand what this paragraph says, I have no idea why or how to work around this limitation. As I am now again working with a model that seems to require a "bidirectional one-to-many association with an index collection", I figured the time was right for follow-up questions: Why does NHibernate have this limitation on associations? It is my impression that the guys behind NHibernate are quite clever, so I assume there is a pretty good reason. What are the common workarounds for this shortcoming? Making the collection a non-indexed bag and adding an explicit Position property to the child class? Any better solutions?

  • WSDL for other protocols different than SOAP?

    - by SDReyes
    From wikipedia: The Web Services Description Language (WSDL, pronounced 'wiz-d?l') is an XML-based language that provides a model for describing Web services. But in most cases, I found that WSDL is used in conjunction with SOAP. but as far as I know, if the WSDL is a language to describe web services. there should be possible to describe another kind of web services different from SOAP. is this possible? any examples? Thanks!

  • insertNewObjectForEntityForName: inManagedObjectContext: returning NSNumber bug?

    - by beinstein
    I'm relatively well versed in CoreData and have been using it for several years with little or no difficulty. All of a sudden I'm now dumbfounded by an error. For the life of me, I can't figure out why insertNewObjectForEntityForName:inManagedObjectContext: is all of a sudden returning some sort of strange instance of NSNumber. GDB says the returned object is of the correct custom subclass of NSManagedObject, but when I go to print a description of the NSManagedObject itself, I get the following error: *** -[NSCFNumber objectID]: unrecognized selector sent to instance 0x3f26f50 What's even stranger, is that I'm able to set some relationships and attributes using setValue:forKey: and all is good. But when I try to set once specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 Has anyone ever encountered anything like this before? I've tried clean all targets, restarting everything, even changing the model to the relationship in question is a to-one instead of a to-many. Nothing makes any difference.

  • paperclip callbacks or simple processor?

    - by holden
    I wanted to run the callback after_post_process but it doesn't seem to work in Rails 3.0.1 using Paperclip 2.3.8. It gives an error: undefined method `_post_process_callbacks' for #<Class:0x102d55ea0> I want to call the Panda API after the file has been uploaded. I would have created my own processor for this, but as Panda handles the processing, and it can upload the files as well, and queue itself for an undetermined duration I thought a callback would do fine. But the callbacks don't seem to work in Rails3. after_post_process :panda_create def panda_create video = Panda::Video.create(:source_url => mp3.url.gsub(/[?]\d*/,''), :profiles => "f4475446032025d7216226ad8987f8e9", :path_format => "blah/1234") end I tried require and include for paperclip in my model but it didn't seem to matter. Anyideas?

  • What is the autoload class names structure, for the root "library" dir in a Zend Framework 1.10.2 pr

    - by Doron
    I have a project I created with Zend Framework 1.10.2. I usually use the application/models directory for new model files I create, and the auto loading is fine, so for example - My_Model_SampleClass is located application/models/SampleClass.php. However, I have just created a custom Exception class, and it does not fit in the models directory inside the application dir (at least the way I see it, I could be logically wrong), so I've created it in the root "library" dir, but I can't seem to find the correct class name + file name to use, so auto loading will be done correctly. BTW, I use a namespace for all custom classes I use, let's assume it's "My".

  • Localization as an afterthought-- screwed?

    - by David
    So I signed on with a startup web development company as a subcontractor. They are putting together a large, complex user/product management system for a company that needs to support multiple levels of hierarchial localization. I signed a 3 month contract, and upon looking at their code, wish I hadn't. They opted to write their own MVC framework (I guess the client company didn't want to use a prewritten one) and it's extremely poorly written. There's SQL scattered throughout almost every model view and controller (and there's no parameter-based find methods, it's all SQL) and they haven't even THOUGHT about localization yet-- something that will have an affect on nearly EVERY query. The due date is 4 months away, and I honestly think we'd make good progress by scrapping the whole thing and going with CakePHP. Have any of you been in a similar situation, and what did you do? PS: This is written in PHP/MySQL.

  • Django file uploads - Just can't work it out

    - by phoebebright
    OK I give up - after 5 solid hours trying to get a django form to upload a file, I've checked out all the links in stackoverflow and googled and googled. Why is it so hard, I just want it to work like the admin file upload? So I get that I need code like: if submitForm.is_valid(): handle_uploaded_file(request.FILES['attachment']) obj = submitForm.save() and I can see my file in request.FILES['attachment'] (yes I have enctype set) but what am I supposed to do in handle_uploaded_file? The examples all have a fixed file name but obviously I want to upload the file to the directory I defined in the model, but I can't see where I can find that. def handle_uploaded_file(f): destination = open('fyi.xml', 'wb+') for chunk in f.chunks(): destination.write(chunk) destination.close() Bet I'm going to feel really stupid when someone points out the obvious!

  • Extending Django-tagging, adding extra field to each tag?

    - by victorhooi
    heya, We're coding together a Django app to handle reviews of newspaper articles. Each newspaper article model will an arbitrary number of tags associated with it. Also, each tag will have an optional ranking (0 to 10). I was thinking of using django-tagging to do this (http://code.google.com/p/django-tagging/), but I'm not sure of the best way to add the ranking to the system. Should I extend django-tagging somehow? (Not sure if this is possible, without changing django-tagging's actual code?). Or is there a better way of achieving this? Cheers, Victor

  • Why is there a limit of max 20 parameters to a clojure function

    - by GuyC
    Hi, there seems to be a limit to the number of parameters a clojure function can take. When defining a function with more than 20 parameters I receive the following: Obviously this can be avoided, but I was hitting this limit porting the execution model of an existing DSL to clojure, and I have constructs in my DSL like the following, which by macro expansion can be mapped to functions quite easily except for this limit: (defAlias nn1 ((element ?e1) (element ?e2)) number "@doc features of the elements are calculated for entry into the first neural network, the result is the score computed by the latter" (nn1-recall (nn1-feature00 ?e1 ?e2) (nn1-feature01 ?e1 ?e2) ... (nn1-feature89 ?e1 ?e2))) which is a DSL statement to call a neural network with 90 input nodes. Can work around it of course, but was wondering where the limit comes from. Thanks.

  • Get Hardware Information for HWs that is not installed

    - by Isaac
    I am pretty sure how to retrieve hardware information with WMI classes. but WMIs have a big limitation: They Just can get information for installed hardwares. I need to retrieve information about CPU (model,speed,etc..),Video Card, Sound Card, USB Ports, etc. I found a really good software (HWiNFO) that can do this even the drivers for hardware parts is not installed. It seems that HWiNFO uses a internal database to give a name for each hardware part. So is there any free library/DLL/component that can do this in Windows XP or higher Note: Although HWiNFO SDK seems good, it's not free. So it doesn't exist! ;) I need a free library.
