  • backbone model validation error

    - by koko
    I got a validation based on backbone fundamentals by addyosmani, but when i try it on my view i can't get the error that the model generated.TIA model.js validate: function(attrs) { var errors = this.errors = {}; if (!attrs.box) errors.box= 'box value is required'; //console.log(errors.box); if (!_.isEmpty(errors)) return errors; } view.js validate: function(model) { console.log("error text--" + model.errors[this.input] || ''); },

  • How can I edit an entity in MVC4 with EF5 which has a unique constraint?

    - by Yoeri
    [HttpPost] public ActionResult Edit(Car car) { if (ModelState.IsValid) { db.Entry(car).State = EntityState.Modified; db.SaveChanges(); return RedirectToAction("Index"); } return View(car); } This is a controller method scaffolded by MCV 4 My "car" entity has a unique field: LicensePlate. I have custom validation on my Entity: Validation: public partial class Car { partial void ValidateObject(ref List<ValidationResult> validationResults) { using (var db = new GarageIncEntities()) { if (db.Cars.Any(c => c.LicensePlate.Equals(this.LicensePlate))) { validationResults.Add( new ValidationResult("This licenseplate already exists.", new string[]{"LicensePlate"})); } } } } should it be usefull, my car entity: public partial class Car:IValidatableObject { public int Id { get; set; } public string Color { get; set; } public int Weight { get; set; } public decimal Price { get; set; } public string LicensePlate { get; set; } public System.DateTime DateOfSale { get; set; } public int Type_Id { get; set; } public int Fuel_Id { get; set; } public virtual CarType Type { get; set; } public virtual Fuel Fuel { get; set; } public IEnumerable<ValidationResult> Validate(ValidationContext validationContext) { var result = new List<ValidationResult>(); ValidateObject(ref result); return result; } partial void ValidateObject(ref List<ValidationResult> validationResults); } QUESTION: Everytime I edit a car, it raises an error: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details. The error is the one raised by my validation, saying it can't edit because there is already a car with that license plate. If anyone could point me in the right direction to fix this, that would be great! I searched but couldn't find anything, so even related posts are welcome!

  • Intellisense for Javascript - not correct in Visual Studio 2010

    - by Finglas
    var obj = document.getElementById("header"); Given the above code snippet, I should be able to wire event handlers. For example, I can wire onMouseDown to the mouse down event, the issue is that Visual Studio does not display this in the Intellisense. I've tried this on both a standalone Javascript file, as well as an MVC project to no luck. Is there anything I'm doing wrong - or is there a way to resolve this?

  • Name for build option (for "make install") specifying where to install web application

    - by Jakub Narebski
    I want to provide 'install' target for Makefile for web application. I'd like to be able to install it, for example like described below: $ make install \ xxxdir=/var/www/cgi-bin (similarly to how one would use 'bindir' for ordinary programs, and 'mandir' / 'infodir' for documentation). Is there any standard (similar to autotools 'bindir', 'sharedir', etc.) for the name of 'xxxdir' variable in above example? How do you think should such build configuration variable be named?

  • ActionScript-3 calling addEventListener more than once

    - by mydiscogr
    I've a little problem, I don't really understand if I can use addEventListener more than one time on the same object (and same callback function) if this case can I have a problem of overflow, or simple flex is so smart to not add again in the same stack same function for examples: var t:CServiceObj = _rModel.userGetBoardJoined(); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk);

  • Mootools 1.2.4 delegation not working in IE8...?

    - by michael
    Hey there everybody-- So I have a listbox next to a form. When the user clicks an option in the select box, I make a request for the related data, returned in a JSON object, which gets put into the form elements. When the form is saved, the request goes thru and the listbox is rebuilt with the updated data. Since it's being rebuilt I'm trying to use delegation on the listbox's parent div for the onchange code. The trouble I'm having is with IE8 (big shock) not firing the delegated event. I have the following HTML: <div id="listwrapper" class="span-10 append-1 last"> <select id="list" name="list" size="20"> <option value="86">Adrian Franklin</option> <option value="16">Adrian McCorvey</option> <option value="196">Virginia Thomas</option> </select> </div> and the following script to go with it: window.addEvent('domready', function() { var jsonreq = new Request.JSON(); $('listwrapper').addEvent('change:relay(select)', function(e) { alert('this doesn't fire in IE8'); e.stop(); var status= $('statuswrapper').empty().addClass('ajax-loading'); jsonreq.options.url = 'de_getformdata.php'; jsonreq.options.method = 'post'; jsonreq.options.data = {'getlist':'<?php echo $getlist ?>','pkey':$('list').value}; jsonreq.onSuccess = function(rObj, rTxt) { status.removeClass('ajax-loading'); for (key in rObj) { status.set('html','You are currently editing '+rObj['cname']); if ($chk($(key))) $(key).value = rObj[key]; } $('lalsoaccomp-yes').set('checked',(($('naccompkey').value > 0)?'true':'false')); $('lalsoaccomp-no').set('checked',(($('naccompkey').value > 0)?'false':'true')); } jsonreq.send(); }); }); (I took out a bit of unrelated stuff). So this all works as expected in firefox, but IE8 refuses to fire the delegated change event on the select element. If I attach the change function directly to the select, then it works just fine. Am I missing something? Does IE8 just not like the :relay? Sidenote: I'm very new to mootools and javascripting, etc, so if there's something that can be improved code-wise, please let me know too.. Thanks!

  • JQuery Tabs: How to get a list of the tab titles

    - by user340254
    As the title suggest, my question is what is the best way to get or build a list of the titles for the set of tabs. I was thinking I would have to build the list in a for loop, but there does not appear to be any 'name' or 'title' property where you could do something like this: var $tabs = $('contentContainer').tabs(); $tabs.tabs( 'title', index );

  • LinQ: Add list to a list

    - by JohannesBoersma
    I have the following code: var columnNames = (from autoExport in dataContext.AutoExports where autoExport.AutoExportTemplate != null && ContainsColumn(autoExport.AutoExportTemplate, realName) select GetDbColumnNames(autoExport.AutoExportTemplate, realName)).ToList(); Where the function GetDbColumns() returns an List<string>. So columNames is of the type List<List<string>>. Is it possible to create a List<string>, so each element of the list of GetDbColumns is added to the result of the LinQ query?

  • Intermittent "Specified cast is invalid" with StructureMap injected data context

    - by FreshCode
    I am intermittently getting an System.InvalidCastException: Specified cast is not valid. error in my repository layer when performing an abstracted SELECT query mapped with LINQ. The error can't be caused by a mismatched database schema since it works intermittently and it's on my local dev machine. Could it be because StructureMap is caching the data context between page requests? If so, how do I tell StructureMap v2.6.1 to inject a new data context argument into my repository for each request? Update: I found this question which correlates my hunch that something was being re-used. Looks like I need to call Dispose on my injected data context. Not sure how I'm going to do this to all my repositories without copypasting a lot of code. Edit: These errors are popping up all over the place whenever I refresh my local machine too quickly. Doesn't look like it's happening on my remote deployment box, but I can't be sure. I changed all my repositories' StructureMap life cycles to HttpContextScoped() and the error persists. Code: public ActionResult Index() { // error happens here, which queries my page repository var page = _branchService.GetPage("welcome"); if (page != null) ViewData["Welcome"] = page.Body; ... } Repository: GetPage boils down to a filtered query mapping in my page repository. public IQueryable<Page> GetPages() { var pages = from p in _db.Pages let categories = GetPageCategories(p.PageId) let revisions = GetRevisions(p.PageId) select new Page { ID = p.PageId, UserID = p.UserId, Slug = p.Slug, Title = p.Title, Description = p.Description, Body = p.Text, Date = p.Date, IsPublished = p.IsPublished, Categories = new LazyList<Category>(categories), Revisions = new LazyList<PageRevision>(revisions) }; return pages; } where _db is an injected data context as an argument, stored in a private variable which I reuse for SELECT queries. Error: Specified cast is not valid. Exception Details: System.InvalidCastException: Specified cast is not valid.

  • JQuery removed background from iframe

    - by Webnet
    I'm trying to remove the background image on a page that's being loaded via an iframe within a lightbox effect. I have verified that body is the correct element within the iframe that's being selected, but I can't get the background image to go away. Am I missing something obvious? var body = jQuery('#fancybox-frame').contents().find('body'); body.css({ 'background': '', 'background-image': '', 'background-color': '#fff' });
