  • Validating only selected fields using ASP.NET MVC 2 and Data Annotations

    - by thinknow
    I'm using Data Annotations with ASP.NET MVC 2 as demonstrated in this post: http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx Everything works fine when creating / updating an entity where all required property values are specified in the form and valid. However, what if I only want to update some of the fields? For example, let's say I have an Account entity with 20 fields, but I only want to update Username and Password? ModelState.IsValid validates against all the properties, regardless of whether they are referenced in the submitted form. How can I get it to validate only the fields that are referenced in the form?

  • Anyone use Distributed VCS in a corporate environment?

    - by Eddie Parker
    I'm curious to hear about people's experiences with distributed version control in a corporate environment. Specifically: Was it difficult to gain adoption? Now that it's in place, is it well liked? What 'model' are you using (hub & spoke? Something else?) Allowing you use hub & spoke, are there any discipline problems with pushing to a central server? I'd like to hear if anyone has non-programmers working within this environment, preferably artists and the like to whom VCS can be a bit daunting. Did it work out for them?

  • Optimizing a large iteration of PHP objects (EAV-based)

    - by Aron Rotteveel
    I am currently working on a project that utilizes the EAV model. This turns out to work quite well, but like many others I am now stumbling upon some performance issues. The data set in this particular case consists of aproximately 2500 entities, each with aprox. 150 attributes. Each entity and each attribute is represented by a PHP-object. Since most parts of the application only iterate through a filtered set of entities, we have not had very large issues yet. Now, however, I am working on an algorithm that requires iteration over the entire dataset, which causes a major impact on performance. This information is perhaps not very much to work with, but since this is an architectural problem, I am hoping for a architectural pattern to help me on the way as well. Each entity, including it's attributes takes up aprox. 500KB of memory.

  • How can I set MAXLENGTH on input fields automatically?

    - by Gary McGill
    I'm using ASP.NET MVC RC2. I have a set of classes that were auto-generated "Linq-to-SQL Classes", where each class models a table in my database. I have some default "edit" views that use the neat-o Html.TextBoxFor helper extension to render HTML input fields for the columns in a table. However, I notice that there is no MAXLENGTH attribute specified in the generated HTML. A quick google shows that you can add explicit attributes using TextBoxFor etc. but that would mean that I need to hard-code the values (and I need to remember to do it for every input). This seems pretty poor, considering that everything was automatically generated directly from the DB, so the size of the columns is known. (Although, to be fair, the web-side stuff has to work with any model objects, not just with Linq-to-SQL objects). Is there any nice way of getting this to do the right thing?

  • Using key().id() on GAE Datastore and reverse geocoding

    - by Ivan Slaughter
    I have 6000 data of district, subdistrict. I need to represent this on dependent dropdown. The datamodel is for example; class Location(db.Model): location_name = db.StringProperty() location_parent = db.IntegerProperty() location_parent is reference to key() or id()? Still cannot decide which one is good. When i use key() as reference then using JSON to create jquery dependent drop down. My page loading/query and rendering time the dropdown is quite slow? Can i use key().id() as drop down option value to lighten up the page load? Any better solution for this parent/child reference for the drop down? For example: for the district record/entities the location-parent is null, for sub district record location_name will contain reference to parent district record. Other issue is to reverse geocoding the location to store or display geoPoint (lat,long)? Is google MAP API always find the exact lat,long of specific region boundaries or any error checking for the result?

  • Imagemagick - File Naming

    - by Josh Crowder
    I am using the convert command to convert a pdf to multiple pngs, I need the naming conventions to be slide-##.png at the moment they come out like slide-1.png but because there is 20+ slides when I loop through them to add them into the model the order comes up wrong, so it looks like slide-1.png slide-10.png slide-11.png and so on, how can I force convert to use double numbers like 01 02 03 and so forth or is there a better way to loop through them, this is the code I have at the moment def convert_keynote_to_slides system('convert -size 640x300 ' + keynote.queued_for_write[:original].path + ' ~/rails/arcticfox/public/system/keynotes/slides/'+File.basename( self.keynote_file_name )+'0%d.png') slide_basename = File.basename( self.keynote_file_name ) files = Dir.entries('/Users/joshcrowder/rails/arcticfox/public/system/keynotes/slides') for file in files #puts file if file.include?(slide_basename +'-') self.slides.build("slide" => "#{file}") if file.include?(slide_basename) end end

  • Django models avoid duplicates

    - by Hulk
    In models, class Getdata(models.Model): title = models.CharField(max_length=255) state = models.CharField(max_length=2, choices=STATE, default="0") name = models.ForeignKey(School) created_by = models.ForeignKey(profile) def __unicode__(self): return self.id() In templates <form> <input type="submit" save the data/> </form> If the user clicks on the save button and the above data is saved in the table how to avoid the duplicates,i.e, if the user again clicks on the same submit button there should not be another entry for the same values.Or is it some this that has to be handeled in views Thanks..

  • ASP.NET MVC2 - using LINQ-generated class

    - by ile
    There are few things not clear to me about ASP.NET MV2. In database I have table Contacts with several fields, and there is an additional field XmlFields of which type is xml. In that field are stored additional description fields. There are 4 classes: Contact class which corresponds to Contact table and is defined by default when creating LINQ classes ContactListView class which inherits Contact class and has some additional properties ContactXmlView class that contains fields from XmlFields field ContactDetailsView class which merges ContactListView and ContactXmlView into one class and this one is used to display data in view pages ContactListView class has re-defined some properties from Contact class (so that I can add [Required] filter used for validation) - but I get warning message: 'ObjectTest.Models.Contacts.ContactListView.FirstName' hides inherited member 'SA.Model.Contact.FirstName'. Use the new keyword if hiding was intended. ContactDetailsView class is also used in a form when creating new contact and adding it to database. I am not sure if this is correct way, and the warning message confuses me a bit. Any advise about this? Thanks, Ile

  • Fat ASP.NET MVC Controllers

    - by Mosh
    Hello, I have been reading about "Fat Controllers" but most of the articles out there focus on pulling the service/repository layer logic out of the controller. However, I have run into a different situation and am wondering if anyone has any ideas for improvement. I have a controller with too many actions and am wondering how I can break this down into many controllers with fewer actions. All these actions are responsible for inserting/updating/removing objects that all belong to the same aggregate. So I'm not quiet keen in having a seperate controller for each class that belongs to this aggregate... To give you more details, this controller is used in a tabbed page. Each tab represents a portion of the data for editing and all the domain model objects used here belong to the same aggregate. Any advice? Cheers, Mosh

  • Why eGet() in EMF returns Object rather than EObject?

    - by Gabriel Šcerbák
    I am working on some code using the EMF framework in Java, but it is really hard to use, e.g. I cannot implement OCL-like query API on top of EMF which would be type-safe. One of the reasons is that eGet() for a EStructuralFeature return just an Object, not EObject. So anything I would write must use much of null checking, type checking and type casting which is unsafe, not performant and cannot be generalized in a reusable way. Why doesn't EMF generate dummy implementations with EObject wrappers for arbitrary Object value? Implementing the EObject and hence the EClass interfaces even with simple throw UnsupportedOperationException is really a pain (the APIs are too big). The same holds for the eContainer() method which makes navigatinng the model upwards painful.

  • Working in consulting company

    - by MichaelT
    I working for some numbers of years in an medium size ecomerce company where we developing and maintaining large distributed ecomerce system that is a core of company business. I thinking to switch job and one of the offers is in consulting company, the model of work there is different you suppose to work for couple of months at different clients of this company developing different project, this mode of working is very different for me and I don't sure if I will like it. From the positive side I will get experience in a lot of different projects in very different problem domains and with a lot of different technologies. From the negative side, I will always be an outsider in all this companies, placed in some far away corner I probably will have little emotional connection to projects I suppose to work on. Do you have some personal experience working in both of this types of companies that you could share ?

  • Faking a dynamic schema in Core Data?

    - by Gouldsc
    From reading the Apple Docs on Core Data, I've learned that you should not use Core Data when you need a dynamic schema. If I wanted to provide the user the ability to create their own properties, in a core data model would it work if I created some "dummy" attributes like "custom decimal 1", "custom decimal 2", "custom text 1", "custom text 2" etc that the user could name and use for their own purposes? Obviously this won't work for relationships, but for simple properties it seems like a reasonable workaround. Will creating a bunch of dummy attributes on my entities that go unused by most users noticeably decrease performance for them? Have any of you tried something like this? Thanks!

  • struts 2 bean is not created

    - by Dewfy
    Hello colleagues! At first some precondition to my question, I'm using struts2 + tiles2 + toplink. NO spring at all. The simplest scenario - is to display list of entities on the page. To optimize resolving JPA's EntityManager I would like to create helper (JPAResourceBean) that implements lazy load of entity manager. For this purposes I'm going to use struts2's bean declaration: <bean name="myfactory" class="my.model.JPAResourceBean" scope="session" optional="false"/> Why bean is not instantiated neither in session? (I'm using s:property just for debug) ... <s:property value="#session.myfactory" default="buka.1"/> ... nor in plain bean list: ... <s:property value="#myfactory" default="buka.2"/> ... May be the second part of question is - how to resolve this bean from java code?

  • C# MVC: User Password Reset Controller: Issues with email addresses as usernames

    - by 109221793
    Hi guys, I have written the code below for resetting users passwords (am using the aspnet membership api) in an C# MVC application, and tested successfully on a sample tutorial application (MVC Music Store). Skip to the end if you wish to read problem description first. InactiveUsers View (Partial View) <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.Web.Security.MembershipUserCollection>" %> <table class="normal" style="width: 100%; background-color: White;"> <tr> <th>User Name</th> <th>Last Activity date</th> <th>Locked Out</th> </tr> <%foreach (MembershipUser user in Model){ %> <tr> <td><%: Html.RouteLink(user.UserName, "AdminPassword", new { username = user.UserName }) %></td> <td><%: user.LastActivityDate %></td> <td><%: user.IsLockedOut %></td> </tr> <% }%> </table> InactiveUsers Controller public ActionResult InactiveUsers() { var users = Membership.GetAllUsers(); return View(users); } changeUserPassword GET and POST Controllers public ActionResult changeUserPassword(string username) { ViewData["username"] = username; return View(); } [HttpPost] public ActionResult changeUserPassword(ChangePasswordModel model, FormCollection values) { string username = values["username"]; string password = values["password"]; string confirmPassword = values["confirmPassword"]; MembershipUser mu = Membership.GetUser(username); if (password == confirmPassword) { if (mu.ChangePassword(mu.ResetPassword(), password)) { return RedirectToAction("Index", "ControlPanel"); } else { ModelState.AddModelError("", "The current password does not meet requirements"); } } return View(); } I also modified the Global.asax.cs file to cater for my route in the InactiveUsers partial: // Added in 10/01/11 RouteTable.Routes.MapRoute( "AdminPassword", // routename "ControlPanel/changeUserPassword/{username}", new { controller = "ControlPanel", action = "changeUserPassword", username = UrlParameter.Optional } ); // END Now, when I tested on the MVC Music Store, all of my usernames were just words, e.g. Administrator, User, etc. However now I am applying this code to a situation in my workplace and it's not working out quite as planned. The usernames used in my workplace are actually email addresses and I think this is what is causing the problem. When I click on the RouteLink in the partial InactiveUsers view, it should bring me to the reset password page with a url that looks like this: http://localhost:83/ControlPanel/changeUserPassword/[email protected], HOWEVER, what happens when I click on the RouteLink is an error is thrown to say that the view changeUserPassword cannot be found, and the URL looks like this: http://localhost:83/ControlPanel/changeUserPassword/example1%40gmail.com - See how the '@' symbol gets messed up? I've also debugged through the code, and in my GET changeUserPassword, the username is populating correctly: [email protected], so I'm thinking it's just the URL that's messing it up? If I type in the URL manually, the changeUserPassword view displays, however the password reset function does not work. An 'Object reference not set to an instance of an object' exception is thrown at the if (mu.ChangePassword(mu.ResetPassword(), password)) line. I think if I could solve the first issue (URL '@' symbol problem) it might help me along with my second issue. Any help would be appreciated :) Stack Trace - as requested Source Error: An unhandled exception was generated during the execution of the current web request.

  • Are there any serialization frameworks for java

    - by Grofit
    I know there is simple, which seems to be a decent enough XML serializer and i know there is Jaxb which seems to do the job as well. However im after something a bit more generic, so I could serialize my model to Xml, Json, Binary etc. So the models are just dumb objects that just get thrown into some sort of serialization factory and then the relevant output is spat out... I dont see any reason why you couldn't do this with reflection, so for a REALLY simple solution get the relevent public properties, cut off the get or set and make that the element name... i.e getPersonName() would become <PersonName>xxxx</PersonName> or PersonName:XXXXX

  • Dealing with XML in ASP.NET MVC

    - by Matt W
    I have a block of XML in a database which is easy enough to pull out using ASP.NET MVC, however I would like to access and modify the XML in an way more consistent with class instances. Is there a way to get the MVC (or any other model) to generate a data access (or perhaps Entity) class set from the DB-stored XML? If the above is rather obtuse, the question could be summarised as; What method would you use to best access and modify XML stored in a database from an ASP.NET MVC application? Thanks, Matt.

  • Django : json serialize a queryset which uses defer() or only()

    - by PlanetUnknown
    Now I've been using json serializer and it works great. I had to modify my queries where I started using the only() & defer() filters, like so - retObj = OBJModel.objects.defer("create_dt").filter(loged_in_dt__gte=dtStart) After I've done the above, suddenly the json serializer is returning empty fields - {"pk": 19047, "model": "OBJModel_deferred_create_dt", "fields": {}} If I remove the defer(), the serializer gives all the data correctly. import json from django.utils import simplejson from django.core import serializers json_serializer = serializers.get_serializer("json")() retObj = OBJModel.objects.defer("create_dt").filter(loged_in_dt__gte=dtStart) json_serializer.serialize(retObj, ensure_ascii=False) I've scratched my head on this for a while now. Any insight would be great. NOTE : I am using django 1.1

  • Is there a way to undo Mocha stubbing of any_instance in Test::Unit

    - by Craig Walker
    Much like this question, I too am using Ryan Bates's nifty_scaffold. It has the desirable aspect of using Mocha's any_instance method to force an "invalid" state in model objects buried behind the controller. Unlike the question I linked to, I'm not using RSpec, but Test::Unit. That means that the two RSpec-centric solutions there won't work for me. Is there a general (ie: works with Test::Unit) way to remove the any_instance stubbing? I believe that it's causing a bug in my tests, and I'd like to verify that.

  • Using a edit template without using Html.EditorFor()

    - by Mark Nijhof
    I have a date time picker combination in a edit template that can be used like Html.EditorFor(x = x.ETA) but now I want to use the same template somewhere where I don't have a model that contains a DateTime property. So I tried Html.Editor("DateWithTime", "Arrival") which uses the correct template, but doesn't assign a value to ViewData.ModelMetadata.PropertyName which is something that my template relies on. It sets the id of the textbox which is obviously important. Is there a way to render the template and assign a id value to the ViewData.ModelMetadata.PropertyName so I can re-use the logic in the template instead of having to copy it?

  • Rails equivalent of respond_to |format| with a straight render

    - by brad
    I'm working with ActiveResource a lot so my service models are only using XML. Thus, I have no need for a respond_to block, I literally just render :xml => @model I can't however figure out how to render a 404 header using this. I've had to resort to respond_to, which I think adds a few unnecessary method calls. Here's what I'm using: respond_to do |format| if (record_found) render :xml => @some_record else format.xml{ head :not_found } end end but I just want something like render :xml => head :not_found which doesn't work. Can anyone tell me the proper syntax?

  • Visio 2010 Reverse Engineer Oracle

    - by digitall
    I have used Visio 2007 in the past to reverse engineer Oracle databases to get a flow scheme. I believe all Office 2007 products were x86 as well which is where I suspect my issue currently lies. I have since upgraded to Visio 2010 x64 and when I go to reverse engineer something from Oracle it shows up under Installed Visio Drivers but I can't seem to create a data source using it. My assumption here is it is because Oracle doesn't play nicely with x64 and with Visio being compiled as x64 I don't even get the option to use it. Has anyone done this with Visio 2010 x64 and Oracle yet? Or are there other tools you would recommend to reverse engineer and get a model such as the one generated by Visio?

  • How can I keep a WPF Image from blocking if the ImageSource references an unreachable Url?

    - by Corey O'Brien
    I'm writing a WPF application and trying to bind an image to my view model with the following XAML: <Image Source="{Binding Author.IconUrl, IsAsync=True}" /> The problem is that the image URLs are defined by users and can often refer to images hosted on intranet web servers. When the WPF application is run remotely, it locks up while trying to resolve the images that are now unreachable. I thought the "IsAsync" binding property would cause the load to happen in the background, but it appears that the DNS resolution may still happen in the main thread? What can I do to keep my app from locking, even if the images are unreachable? Thanks, Corey

  • Populating an association with children in factory_girl

    - by Craig Walker
    I have a model Foo that has_many 'Bar'. I have a factory_girl factory for each of these objects. The factory for Bar has an association to Foo; it will instantiate a Foo when it creates the Bar. I'd like a Factory that creates a Foo that contains a Bar. Ideally this Bar would be created through the :bar factory, and respect the build strategy (create/build) used to create the Foo. I know I could just call the :bar factory and then grab the Foo reference from the new Bar. I'd like to avoid this; in my test case, the important object is Foo; calling the Bar factory seems a bit circuitous. Also, I can see the need for a Foo with multiple Bars. Is this possible in factory_girl? How do you define this relationship in the parent?
