  • mvc action name in url

    - by Paul
    UPDATE: My model going into the save method is PartialViewModel, which in the save method, is pushed into the index's ContactViewModel and sent back. This wasn't clear. I am playing around with MVC3, and have a contact controller with a SaveDetails action. The index cshtml has a partial with a form whose action is pointing to this controller. When I submit the form not having completed it fully, thereby firing the validation, the url now contains the SaveDetails action name (http://localhost:7401/Contact/SaveDetails). The form code is: @using (Html.BeginForm("SaveDetails", "Contact")) { ... } The controller action looks like this: public ActionResult SaveDetails(Models.PartialsViewModel pvm) { return View("Index", new ContactViewModel{ PartialsViewModel = pvm } ); } What am I doing wrong?

  • LinqToSql: How can I create a projection to adhere to DRY?

    - by mhutter
    Just wondering if there is a way to take some of the repitition out of a LINQ to SQL projected type. Example: Table: Address Fields: AddressID, HouseNumber, Street, City, State, Zip, +20 more Class MyAddress: AddressID, HouseNumber, Street (Only 3 fields) LINQ: from a in db.Addresses select new MyAddress { AddressID = a.AddressID, HouseNumber = a.HouseNumber, Street = a.Street } The above query works perfectly, and I understand why something like this will return all 20+ fields in each row: from a in db.Addresses select new MyAddress(a); class MyAddress { public MyAddress(Address a) { this.AddressID = a.AddressID, this.HouseNumber = a.HouseNumber, this.Street = a.Street } } Which leads me to my Question: Is it possible to implement some kind of helper function or extension method to "map" from the LINQ model to MyAddress yet only return the necessary fields in the query result rather than all of the fields?

  • problem with dropdownlist in mvc application

    - by czuroski
    Hello, I am trying to work with an HTML.DropDownList in MVC and am not getting the expected return values. Here is my implementation for the selectList to bind to the drop down - IEnumerable<status> stat = _provider.GetAllStatuses(); Statuses = new SelectList(stat.ToList(), "id", "name", i.status.id); And here is my view - <%= Html.DropDownList("Status",Model.Statuses) %> I am getting an error when trying to run updatemodel in my controller. I then tried to individually set each object. It turns out that I am not getting a single int from the formvalue as I would expect to. Instead, I am getting a value like "5,10,2,3". I think this is coming from how I set up my selectlist, but I'm not exactly sure. Can anyone see an error in the way I am setting up this dd? Thanks for any help, and let me know if I can clarify anything.

  • CakePHP repeats same queries

    - by Rytis
    I have a model structure: Category hasMany Product hasMany Stockitem belongsTo Warehouse, Manufacturer. I fetch data with this code, using containable to be able to filter deeper in the associated models: $this->Category->find('all', array( 'conditions' => array('Category.id' => $category_id), 'contain' => array( 'Product' => array( 'Stockitem' => array( 'conditions' => array('Stockitem.warehouse_id' => $warehouse_id), 'Warehouse', 'Manufacturer', ) ) ), ) ); Data structure is returned just fine, however, I get multiple repeating queries like, sometimes hundreds of such queries in a row, based on dataset. SELECT `Warehouse`.`id`, `Warehouse`.`title` FROM `beta_warehouses` AS `Warehouse` WHERE `Warehouse`.`id` = 2 Basically, when building data structure Cake is fetching data from mysql over and over again, for each row. We have datasets of several thousand rows, and I have a feeling that it's going to impact performance. Is it possible to make it cache results and not repeat same queries?

  • Hibernate and Child Objects (add versus clear)

    - by tyndall
    Lets say I have domain model with Automobile and Wheels. Wheels is a List of Wheels Wheels has a many-to-one relationship to Automobile. If I get an object back from Hibernate and it has 4 wheels. I take that object remove the 4 wheels and add 4. And then Save. If I ask Hibernate for the object again and it returns an auto with 8 wheels... what are we doing wrong? I don't have access to the source for a few days but want to give our Java devs a push in the right direction. Thanks.

  • std::string constructor corrupts pointer

    - by computergeek6
    I have an Entity class, which contains 3 pointers: m_rigidBody, m_entity, and m_parent. Somewhere in Entity::setModel(std::string model), it's crashing. Apparently, this is caused by bad data in m_entity. The weird thing is that I nulled it in the constructor and haven't touched it since then. I debugged it and put a watchpoint on it, and it comes up that the m_entity member is being changed in the constructor for std::string that's being called while converting a const char* into an std::string for the setModel call. I'm running on a Mac, if that helps (I think I remember some problem with std::string on the Mac). Any ideas about what's going on?

  • Timespan not accepting day in MVC3

    - by middelpat
    I have a MVC3 application in which i want to set a timespan to for example 2 days and 5 hours. when i enter 02:05:00:00 it gives me the following exception: System.OverflowException: SqlDbType.Time overflow. Value '2.05:00:00' is out of range. Must be between 00:00:00.0000000 and 23:59:59.9999999. When i enter 05:00:00 it correctly saves 5 hours into the database. according to MSDN timespan has a property for days. How do i correctly set the days? Model: public class ProductionTimeVM { [Required] public TimeSpan DefaultTime { get; set; } } In my view i just use: @Html.TextBoxFor(x => x.DefaultTime) For my controller: public ActionResult SaveProductionTime(ProductionTimeVM vm) { ProductionTime productionTime = new ProductionTime(); productionTime.Default = vm.DefaultTime; //some more code } Any idea's?

  • Parsing HTML "Visually"

    - by Midhat
    OKay I am at loss how to name this question. I have some HTML files, probably written by lord Lucifier himself, that I need to parse. It consists of many segments like this, among other html tags <p>HeadingNumber</p> <p style="text-indent:number;margin-top:neg_num ">Heading Text</p> <p>Body</p> Notice that the heading number and text are in seperate p tags, aligned in a horizontal line by css. the css may be whatever Lucifier fancies, a mixture of indents, paddings, margins and positions. However that line is a single object in my business model and should be kept as such. So How do I detect whether two p elements are visually in a single line and process them accordingly. I believe the HTML files are well formed if it helps.

  • Why do most Database developers hate Agile

    - by Calm Storm
    To me "Agile" methodology is a common-sense oriented approach and one that should likely be adopted for most software projects. I find that while a lot of Middle Tier Developers and Front End developers find it a very sensible project delivery model, plenty of Database developers (and good ones) seem to be totally against it. They are very keen on knowing the biggest picture and designing a database solution that will cater to that. They do not seem to like "Vertical striping" of a functionality. They would rather see the complete design document/feature document instead of concentrating on small user stories. Sarcasm aside, can someone realistically provide some insight as to why this mentality is prevalent? Especially DB devs? What would be a convincing argument against that?

  • Rails 4 json return on API

    - by El - Key
    I'm creating an API on my application. I currently overrided the as_json method in my model in order to be able to get attached files as well as logo from Paperclip : def as_json( options = {} ) super.merge(logo_small: self.logo.url(:small), logo_large: self.logo.url(:large), taxe: self.taxe, attachments: self.attachments) end Then within my controller, I'm doing : def index @products = current_user.products respond_with @products end def show respond_with @product end The problem is that on the index, I don't want get all the attachments. I only need it on the show method. So I tried it : def index @products = current_user.products respond_with @products, except: [:attachments] end But unfortunately it's not working. How can I do to not send :attachments? Thanks

  • HTML input text box vs CakePHP Automagic Form Elements

    - by kwokwai
    Hi all, I was manually creating a simple form with one input text box field like this: <form action="/user/add" method="post"> <input type="text" name="data[user_id]" value="1"> But when I call $this->model->save($this->data) in the Controller, nothing was saved to the Table. Only when I used this and the data in the field was written to the database successfully: $form->create(null, array('url' => '/user/add')); echo $form->input('user_id', array('label' => 'User ID', 'value' => '1'));

  • CakePHP hasAndBelongsToMany (HABTM) Delete Joining Record

    - by Jason McCreary
    I have a HABTM relationship between Users and Locations. Both Models have the appropriate $hasAndBelongsToMany variable set. When I managing User Locations, I want to delete the association between the User and Location, but not the Location. Clearly this Location could belong to other users. I would expect the following code to delete just the join table record provided the HABTM associations, but it deleted both records. $this->Weather->deleteAll(array('Weather.id' => $this->data['weather_ids'], false); However, I am new to CakePHP, so I am sure I am missing something. I have tried setting cascade to false and changing the Model order with User, User-Weather, Weather-User. No luck. Thanks in advance for any help.

  • If Nvidia Shield can stream a game via wifi, why can I not do the same via ethernet to any other PC?

    - by Enigma
    I think it absurd that a wireless game streaming solution is the *first to hit the market when a 1000mbps+ Ethernet connection would accomplish the same feat with roughly 6x the available bandwidth. I can only assume that there must be some reason behind this or a limitation preventing this, but what? 150mbps wifi is in no way superior to a 1000mbps LAN connection aside from well wireless mobility. Not only that but I have a secondary laptop and desktop which should by hardware comparison completely outperform anything the Tegra in the Nvidia Shield can do. Is this all just a marketing scheme to force people to buy the shield for the streaming benefit? Chief among these is that NVIDIA’s Shield handheld game console will be getting a microconsole-like mode, dubbed “Shield Console Mode”, that will allow the handheld to be converted into a more traditional TV-connected console. In console mode Shield can be controlled with a Bluetooth controller, and in accordance with the higher resolution of TVs will accept 1080p game streaming from a suitably equipped PC, versus 720p in handheld mode. With that said 1080p streaming will require additional bandwidth, and while 720p can be done over WiFi NVIDIA will be requiring a hardline GigE connection for 1080p streaming (note that Shield doesn’t have Ethernet, so this is presumably being done over USB). Streaming aside, in console mode Shield will also support its traditional local gaming/application functionality. - http://www.anandtech.com/show/7435/nvidia-consolidates-game-streaming-tech-under-gamestream-brand-announces-shield-console-mode ^ This is not acceptable for me for a number of reasons not to mention the ridiculousness of having a little screen+controller unit sitting there while using a secondary controller and screen instead. That kind of redundant absurdity exemplifies how wrong of a solution that is. They need a second product for this solution without the screen or controller for it to make sense... at which point your just buying a little computer that does what most other larger computers do better. All that is required, by my understanding, is the ability to decode H.264 video compression and transmit control/feedback so by any logical comparison, one (Nvidia especially) should have no difficulty in creating an application for PC's (win32/64 environment) that does the exact same thing their android app does. I have 2 video cards capable of streaming (encoding) H.264 so by right they must be capable of decoding it I would think. I haven't found anything stating plans to allow non-shield owners to do this. Can a third party create this software or does it hinge on some limitation that only Nvidia can overcome? (*) - perhaps this isn't the first but afaik it is the first complete package.

  • CakePHP hasOne ineffeciency?

    - by Andre
    I was looking at examples on the CakePHP website, in particular hasOne used in linking models. http://book.cakephp.org/view/78/Associations-Linking-Models-Together My question is this, is CakePHP using two queries to build the array structure of data returned in a model that uses hasOne linkage? Taken from CakePHP: //Sample results from a $this-User-find() call. Array ( [User] => Array ( [id] => 121 [name] => Gwoo the Kungwoo [created] => 2007-05-01 10:31:01 ) [Profile] => Array ( [id] => 12 [user_id] => 121 [skill] => Baking Cakes [created] => 2007-05-01 10:31:01 ) ) Hope this all makes sense.

  • Help with porting thread functionality: Win32 --> .Net

    - by JimDaniel
    Hi, I am responsible for porting a class from legacy Win32 code to .Net and I have come across a threading model that I'm not sure how best to implement in .Net. Basically the Win32 has one worker thread, which calls WaitForMultipleObjects() and executes the particular piece of code when a particular object has been triggered. This has a sort of first-come-first-serve effect that I need to emulate in my own code. But I'm not sure how best to do this in .Net. Does anyone have any idea? I see that there is no equivalent of WaitForMultipleObjects() in .Net, only the ThreadPool class, which seems to provide most of what I need, but I'm not sure if it's the best, since I only have four objects total to wait and execute code for. Thanks, Daniel

  • How to make an application scriptable in Linux

    - by arx
    I've written an application in C++ that takes a complex binary file format and translates it into human-readable text. Having edited the text you can recompile it back into the binary file format. This would be more useful if the application's internal object model was scriptable. On Windows I'd expose the objects using COM or .Net but I want this to work on Linux. I could embed a scripting language but that's a fair bit of work, and limits users to the scripting language I choose. Ideally, I'm looking for some way of exposing a scriptable DOM from my application that is: Widely support in scripting languages (without writing language-specific wrappers) Cross-platform (but Linux support is most important) In-process (but this isn't essential)

  • Multiple calculations on the same set of data: ruby or database?

    - by Pierre
    Hi, I have a model Transaction for which I need to display the results of many calculations on many fields for a subset of transactions. I've seen 2 ways to do it, but am not sure which is the best. I'm after the one that will have the least impact in terms of performance when data set grows and number of concurrent users increases. data[:total_before] = Transaction.where(xxx).sum(:amount_before) data[:total_after] = Transaction.where(xxx).sum(:amount_after) ... or transactions = Transaction.where(xxx) data[:total_before]= transactions.inject(0) {|s, e| s + e.amount_before } data[:total_after]= transactions.inject(0) {|s, e| s + e.amount_after } ... Which one should I choose? (or is there a 3rd, better way?) Thanks, P.

  • Linq to NHibernate - How to return a parent object with only certain child objects included

    - by vakman
    Given a simplified model like the following: public class Enquiry { public virtual DateTime Created { get; set; } public virtual Sender Sender { get; set; } } public class Sender { public virtual IList<Enquiry> Enquiries { get; set; } } How can you construct a Linq to Nhibernate query such that it gives you back a list of senders and their enquiries where the enquiries meet some criteria. I have tried something like this: return session.Linq<Enquiry>() .Where(enquiry => enquiry.Created < DateTime.Now) .Select(enquiry => enquiry.Sender) In this case I get an InvalidCastException saying you can't cast type Sender to type Enquiry. Any pointers on how I can do this without using HQL?

  • Newbie question attribute from associated table not showing up in index view

    - by Lauren
    Hi I know this is something simple I am doing wrong. I have three tables, installation, neighborhood, schools Installation: has_many :schools has_many :neighborhoods Neighborhood: has_many :installations has_many :schools Schools: belongs_to :installations belongs_to :neighborhoods I can't figure out how to show the name of the neighborhood the school is located in on the index view. I can get it to show on the show view once I have the school id. But on the index view I can't figure out what to put in the controller that will allow me to access the neighborhood name from the neighborhood_id that is in the School model. I am sure this is so easy and I am screwing up something stupid. HELP!

  • Why does the android emulator camera stop unexpectedly?

    - by user490074
    I am using Android 2.2 (API Level 8). The camera is enabled in the manifest. When I try the camera icon provided by the emulator model, it runs for a few seconds showing a gray box moving around a black and white checkerboard, then dies with the error message: Sorry! The application Camera (process com.android.camera) has stopped unexpectedly. Please try again. Trying again, of course, doesn't help. I am using the provided emulator camera to compare behavior with a camera application I am working on. Why does the android emulator camera stop unexpectedly?

  • Exposing entities via a nHibernate implementation RIA Services with querystring queries

    - by illdev
    I once read a blog post and cannot find it anymore. drat! It was about a guy who setup a wcf service (I guess RIA, but could have been something else) exposing the model via IQueryable to the querystring. Sou you could say http://host/articles/123/ratings and you'd get a list (soap or json) of serialized Rating entities (the properties which had some attribute attached) which pertained to an article with id 123. All this with nHibernate / nh linq in the back and in surprisingly few lines of code. Anyone knows what I am talking about? Experiences, suggestions?

  • Proper way to reload a python module from the console

    - by ensnare
    I'm debugging from the python console and would like to reload a module every time I make a change so I don't have to exit the console and re-enter it. I'm doing: >>> from project.model.user import * >>> reload(user) but I receive: >>>NameError: name 'user' is not defined What is the proper way to reload the entire user class? Is there a better way to do this, perhaps auto-updating while debugging? Thanks.

  • Eager loading in EF1.0

    - by Dave Swersky
    I have a many-to-many relationship: Application - Applications_Servers - Server This is set up in my Entity Data Model and all is well. My problem is that I'd like to eager-load the whole graph of Applications so that I have an IEnumerable<Applications>, each Application member populated with the Servers collection associated by the many-to-many relationship. Normally this wouldn't be a problem, but according to my research there must be a navigation property between Application and Server. This is not the case for me because my Applications_Servers join table has more in it than just the two keys. Therefore, there is no navigation property directly between Application and Server, and this doesn't work: var apps = (from a in context.Application.Include("Server") select a).ToList(); I get an error saying there is no navigation property on Application called "Server", and that's correct, there is none. How do I write the query to eager-load my Applications with their Servers in this case?

  • URIs vs Hidden Forms

    - by NateDogg
    I'm working in the Codeigniter framework, and want to send requests to my controller/model that have several variables involved. Is there a difference between passing those variables via a hidden form (i.e. using "post") as opposed to passing them through URIs (e.g. 'travel/$month/$day/')? What about security concerns? e.g. URIs: http://www.example.com/travel/$month/$day/ Hidden Form: form_hidden('month',$month); form_hidden('day',$day);
