  • XVal validation framework

    - by csetzkorn
    Hi, I started using this validation framework: http://blog.stevensanderson.com/2009/01/10/xval-a-validation-framework-for-aspnet-mvc/ Steve mentions that the DataAnnotationsValidationRunner implementation is slightly naive. Why is this and are there better implementations? I am also looking for a good example that uses this framework to validate database dependent business rules. Any pointers would be very much appreciated. Thanks. Christian

  • MVC Partial View Postback - Jquery validation lost

    - by user415394
    I have a partial view which uses Jquery Valiation. This works OK when initially loaded, however after I do a ajax postback and return the partial view from the server with an error showing, the jquery validation seems to be lost. In that, if I delete a required field and hit save the partial view gets submitted, when I would expect it to show an error message and not get submitted. Does Jquery validation need to be initialised somehow for the form in the partial view?

  • When does validation happen in Core Data?

    - by dontWatchMyProfile
    From the docs: If you make changes to managed objects associated with a given context, those changes remain local to that context until you commit the changes by sending the context a save: message. At that point—provided that there are no validation errors—the changes are committed to the store. So does that essentially mean, that validation happens automatically as soon as I call -save?

  • How to raise a validation event from a key press

    - by flavour404
    Hi, I want to raise the: private void txtbox_startdate_Validating(object sender, System.ComponentModel.CancelEventArgs e) {} Function from a key leave event. The leave event looks like: private void txtbox_startdate_Leave(object sender, EventArgs e) {} The trouble is of course if I try and call it in this manner: txtbox_startdate_Validating(sender, e) An error is raised because in this case 'e' is an EventArgs whereas the validation function wants a System.ComponentModel.CancelEventArgs and so, how do I convert EventArgs to a System.ComponentModel.CancelEventArgs or create one so that I can call my validation function? Thanks, R.

    - by GibboK
    I'm using ASp.Net MVC and EF 4.3.1. Using POCO t4 template I'm able to create the POCO classes for my model but not validation. At the moment I'm using Partial Classes with MetaData for adding the annotation (leaving intact the POCO auto generated). My question: Could you point me out a tutorial, or show me an example of code or a link to a T4 template the also include automatic VALIDATION for my POCO? THanks

  • How can I highlight empty fields in ASP.NET MVC 2 before model binding has occurred?

    - by Richard Poole
    I'm trying to highlight certain form fields (let's call them important fields) when they're empty. In essence, they should behave a bit like required fields, but they should be highlighted if they are empty when the user first GETs the form, before POST & model validation has occurred. The user can also ignore the warnings and submit the form when these fields are empty (i.e. empty important fields won't cause ModelState.IsValid to be false). Ideally it needs to work server-side (empty important fields are highlighted with warning message on GET) and client-side (highlighted if empty when losing focus). I've thought of a few ways of doing this, but I'm hoping some bright spark can come up with a nice elegant solution... Just use a CSS class to flag important fields Update every view/template to render important fields with an important CSS class. Write some jQuery to highlight empty important fields when the DOM is ready and hook their blur events so highlights & warning messages can be shown/hidden as appropriate. Pros: Quick and easy. Cons: Unnecessary duplication of importance flags and warning messages across views & templates. Clients with JavaScript disabled will never see highlights/warnings. Custom data annotation and client-side validator Create classes similar to RequiredAttribute, RequiredAttributeAdapter and ModelClientValidationRequiredRule, and register the adapter with DataAnnotationsModelValidatorProvider.RegisterAdapter. Create a client-side validator like this that responds to the blur event. Pros: Data annotation follows DRY principle (Html.ValidationMessageFor<T> picks up field importance and warning message from attribute, no duplication). Cons: Must call TryValidateModel from GET actions to ensure empty fields are decorated. Not technically validation (client- & server-side rules don't match) so it's at the mercy of framework changes. Clients with JavaScript disabled will never see highlights/warnings. Clone the entire validation framework It strikes me that I'm trying to achieve exactly the same thing as validation but with warnings rather than errors. It needs to run before model binding (and therefore validation) has occurred. Perhaps it's worth designing a similar framework with annotations like Required, RegularExpression, StringLength, etc. that somehow cause Html.TextBoxFor<T> etc. to render the warning CSS class and Html.ValidationMessageFor<T> to emit the warning message and JSON needed to enable client-side blur checks. Pros: Sounds like something MVC 2 could do with out of the box. Cons: Way too much effort for my current requirement! I'm swaying towards option 1. Can anyone think of a better solution?

  • jQuery validation: how to customize trigger and response

    - by user302307
    I am new with jQuery. I have a servlet based application which render an HTML form. This form is submitted via a function and the submit button IS NOT submit button in HTML. It's a regular button that calls a javascript function to do the submission. When running the submission function, the servlet also run a function called doCheck() which is in javascript. This doCheck() function can be defined per page basis. if doCheck returns false, then the servlet will stop the submission; else it will submit the form. I want to use jQuery validation to fit the servlet application. Is there a way to customize jQuery validation to be triggered manually (ie. only when doCheck() is executed) but at the same time provides continuous check on the UI (ie. if one type invalid number in date field, it will gives the appropriate msg when onblur event happen)? Is there a way to make jQuery validation return true or false? Thank you.

  • Validation without ServiceLocator

    - by Dmitriy Nagirnyak
    Hi, I am getting back again and again to it thinking about the best way to perform validation on POCO objects that need access to some context (ISession in NH, IRepository for example). The only option I still can see is to use S*ervice Locator*, so my validation would look like: public User : ICanValidate { public User() {} // We need this constructor (so no context known) public virtual string Username { get; set; } public IEnumerable<ValidationError> Validate() { if (ServiceLocator.GetService<IUserRepository>().FindUserByUsername(Username) != null) yield return new ValidationError("Username", "User already exists.") } } I already use Inversion Of control and Dependency Injection and really don't like the ServiceLocator due to number of facts: Harder to maintain implicit dependencies. Harder to test the code. Potential threading issues. Explicit dependency only on the ServiceLocator. The code becomes harder to understand. Need to register the ServiceLocator interfaces during the testing. But on the other side, with plain POCO objects, I do not see any other way of performing the validation like above without ServiceLocator and only using IoC/DI. So the question would be: is there any way to use DI/IoC for the situation described above? Thanks, Dmitriy.

  • Custom Validation Attribute with Custom Model Binder in MVC 2

    - by griegs
    I apologise for the amount of code I have included. I've tried to keep it to a minimum. I'm trying to have a Custom Validator Attribute on my model as well as a Custom Model binder. The Attribute and the Binder work great seperately but if I have both, then the Validation Attribute no longer works. Here is my code snipped for readability. If I leave out the code in global.asax the custom validation fires but not if I have the custom binder enabled. Validation Attribute; public class IsPhoneNumberAttribute : ValidationAttribute { public override bool IsValid(object value) { //do some checking on 'value' here return true; } } Useage of the attribute in my model; [Required(ErrorMessage = "Please provide a contact number")] [IsPhoneNumberAttribute(ErrorMessage = "Not a valid phone number")] public string Phone { get; set; } Custom Model Binder; public class CustomContactUsBinder : DefaultModelBinder { protected override void OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext) { ContactFormViewModel contactFormViewModel = bindingContext.Model as ContactFormViewModel; if (!String.IsNullOrEmpty(contactFormViewModel.Phone)) if (contactFormViewModel.Phone.Length > 10) bindingContext.ModelState.AddModelError("Phone", "Phone is too long."); } } Global asax; System.Web.Mvc.ModelBinders.Binders[typeof(ContactFormViewModel)] = new CustomContactUsBinder();

  • Django server side AJAX validation

    - by MMRUser
    Hi, Recently I'm trying to implement a simple Django application that include one server side AJAX validation, it's a simple form input field (username). I have used a pre-built in line AJAX validation library which uses jQuery. So the code goes like this HTML snippet <form id="simpleform" method="post" action="/done/"> Username:<input value="" class="validate[required,custom[noSpecialCaracters],length[0,20],ajax[ajaxUser]]" type="text" name="user" id="user" /> <input class="submit" type="submit" value="Validate"/> </form> The server side code snippet (embedded in to a php script) /* RECEIVE VALUE */ $validateValue=$_POST['validateValue']; $validateId=$_POST['validateId']; $validateError=$_POST['validateError']; /* RETURN VALUE */ $arrayToJs = array(); $arrayToJs[0] = $validateId; $arrayToJs[1] = $validateError; if($validateValue =="testname"){ // validate?? $arrayToJs[2] = "true"; // RETURN TRUE echo '{"jsonValidateReturn":'.json_encode($arrayToJs).'}'; // RETURN ARRAY WITH success }else{ for($x=0;$x<1000000;$x++){ if($x == 990000){ $arrayToJs[2] = "false"; echo '{"jsonValidateReturn":'.json_encode($arrayToJs).'}'; // RETURN ARRAY WITH ERROR } } } So my question is that how do I get this in to Python code (in order to use in Django environment) how do I get the user name from the input field in to the back end,I think the server side script snippet already does it but I want to know how to use this in my Pyhon code,and this is my first time using jQuery and I do need to use this same exact validation library. Your valuable corporation is needed. Thanks.

  • jQuery Validation error...

    - by Povylas
    Hi, I have been struggling with this jQuery Validation Plugin. Here is the code: <script type="text/javascript"> $(function() { var validator = $('#signup').validate({ errorElement: 'span', rules: { username: { required: true, minlenght: 6 //remote: "check-username.php" }, password: { required: true, minlength: 5 }, confirm_password: { required: true, minlength: 5, equalTo: "#password" }, email: { required: true, email: true }, agree: "required" }, messages: { username: { required: "Please enter a username", minlength: "Your username must consist of at least 6 characters" //remote: "Somenoe have already chosen nick like this." }, password: { required: "Please provide a password", minlength: "Your password must be at least 5 characters long" }, confirm_password: { required: "Please provide a password", minlength: "Your password must be at least 5 characters long", equalTo: "Please enter the same password as above" }, email: "Please enter a valid email address", agree: "Please accept our policy" } }); var root = $("#wizard").scrollable({size: 1, clickable: false}); // some variables that we need var api = root.scrollable(); $("#data").click(function() { validator.form(); }); // validation logic is done inside the onBeforeSeek callback api.onBeforeSeek(function(event, i) { if($("#signup").valid() == false){ return false; }else{ return true; } $("#status li").removeClass("active").eq(i).addClass("active"); }); //if tab is pressed on the next button seek to next page root.find("button.next").keydown(function(e) { if (e.keyCode == 9) { // seeks to next tab by executing our validation routine api.next(); e.preventDefault(); } }); $('button.fin').click(function(){ parent.$.fn.fancybox.close() }); }); </script> And here is the error: $.validator.methods[method] is undefined http://www.vvv.vhost.lt/js/jquery-validate/jquery.validate.min.js Line 15 I am completely confused... Maybe some kind of handler is needed? I would be grateful for any kind of answer.
