  • NerdDinner form validation DataAnnotations ERROR in MVC2 when a form field is left blank.

    - by Edward Burns
    Platform: Windows 7 Ultimate IDE: Visual Studio 2010 Ultimate Web Environment: ASP.NET MVC 2 Database: SQL Server 2008 R2 Express Data Access: Entity Framework 4 Form Validation: DataAnnotations Sample App: NerdDinner from Wrox Pro ASP.NET MVC 2 Book: Wrox Professional MVC 2 Problem with Chapter 1 - Section: "Integrating Validation and Business Rule Logic with Model Classes" (pages 33 to 35) ERROR Synopsis: NerdDinner form validation ERROR with DataAnnotations and db nulls. DataAnnotations in sample code does not work when the database fields are set to not allow nulls. ERROR occurs with the code from the book and with the sample code downloaded from codeplex. Help! I'm really frustrated by this!! I can't believe something so simple just doesn't work??? Steps to reproduce ERROR: Set Database fields to not allow NULLs (See Picture) Set NerdDinnerEntityModel Dinner class fields' Nullable property to false (See Picture) Add DataAnnotations for Dinner_Validation class (CODE A) Create Dinner repository class (CODE B) Add CREATE action to DinnerController (CODE C) This is blank form before posting (See Picture) This null ERROR occurs when posting a blank form which should be intercepted by the Dinner_Validation class DataAnnotations. Note ERROR message says that "This property cannot be set to a null value. WTH??? (See Picture) The next ERROR occurs during the edit process. Here is the Edit controller action (CODE D) This is the "Edit" form with intentionally wrong input to test Dinner Validation DataAnnotations (See Picture) The ERROR occurs again when posting the edit form with blank form fields. The post request should be intercepted by the Dinner_Validation class DataAnnotations. Same null entry error. WTH??? (See Picture) See screen shots at: http://www.intermedia4web.com/temp/nerdDinner/StackOverflowNerdDinnerQuestionshort.png CODE A: [MetadataType(typeof(Dinner_Validation))] public partial class Dinner { } [Bind(Include = "Title, EventDate, Description, Address, Country, ContactPhone, Latitude, Longitude")] public class Dinner_Validation { [Required(ErrorMessage = "Title is required")] [StringLength(50, ErrorMessage = "Title may not be longer than 50 characters")] public string Title { get; set; } [Required(ErrorMessage = "Description is required")] [StringLength(265, ErrorMessage = "Description must be 256 characters or less")] public string Description { get; set; } [Required(ErrorMessage="Event date is required")] public DateTime EventDate { get; set; } [Required(ErrorMessage = "Address is required")] public string Address { get; set; } [Required(ErrorMessage = "Country is required")] public string Country { get; set; } [Required(ErrorMessage = "Contact phone is required")] public string ContactPhone { get; set; } [Required(ErrorMessage = "Latitude is required")] public double Latitude { get; set; } [Required(ErrorMessage = "Longitude is required")] public double Longitude { get; set; } } CODE B: public class DinnerRepository { private NerdDinnerEntities _NerdDinnerEntity = new NerdDinnerEntities(); // Query Method public IQueryable<Dinner> FindAllDinners() { return _NerdDinnerEntity.Dinners; } // Query Method public IQueryable<Dinner> FindUpcomingDinners() { return from dinner in _NerdDinnerEntity.Dinners where dinner.EventDate > DateTime.Now orderby dinner.EventDate select dinner; } // Query Method public Dinner GetDinner(int id) { return _NerdDinnerEntity.Dinners.FirstOrDefault(d => d.DinnerID == id); } // Insert Method public void Add(Dinner dinner) { _NerdDinnerEntity.Dinners.AddObject(dinner); } // Delete Method public void Delete(Dinner dinner) { foreach (var rsvp in dinner.RSVPs) { _NerdDinnerEntity.RSVPs.DeleteObject(rsvp); } _NerdDinnerEntity.Dinners.DeleteObject(dinner); } // Persistence Method public void Save() { _NerdDinnerEntity.SaveChanges(); } } CODE C: // ************************************** // GET: /Dinners/Create/ // ************************************** public ActionResult Create() { Dinner dinner = new Dinner() { EventDate = DateTime.Now.AddDays(7) }; return View(dinner); } // ************************************** // POST: /Dinners/Create/ // ************************************** [HttpPost] public ActionResult Create(Dinner dinner) { if (ModelState.IsValid) { dinner.HostedBy = "The Code Dude"; _dinnerRepository.Add(dinner); _dinnerRepository.Save(); return RedirectToAction("Details", new { id = dinner.DinnerID }); } else { return View(dinner); } } CODE D: // ************************************** // GET: /Dinners/Edit/{id} // ************************************** public ActionResult Edit(int id) { Dinner dinner = _dinnerRepository.GetDinner(id); return View(dinner); } // ************************************** // POST: /Dinners/Edit/{id} // ************************************** [HttpPost] public ActionResult Edit(int id, FormCollection formValues) { Dinner dinner = _dinnerRepository.GetDinner(id); if (TryUpdateModel(dinner)){ _dinnerRepository.Save(); return RedirectToAction("Details", new { id=dinner.DinnerID }); } return View(dinner); } I have sent Wrox and one of the authors a request for help but have not heard back from anyone. Readers of the book cannot even continue to finish the rest of chapter 1 because of these errors. Even if I download the latest build from Codeplex, it still has the same errors. Can someone please help me and tell me what needs to be fixed? Thanks - Ed.

  • Does the DataAnnotations.DisplayAttribute.Order property not work with ASP.NET MVC 2?

    - by Zack Peterson
    I set values for the Order property of the Display attribute in my model metadata. [MetadataType(typeof(OccasionMetadata))] public partial class Occasion { private class OccasionMetadata { [ScaffoldColumn(false)] public object Id { get; set; } [Required] [DisplayName("Title")] [Display(Order = 0)] public object Designation { get; set; } [Required] [DataType(DataType.MultilineText)] [Display(Order = 3)] public object Summary { get; set; } [Required] [DataType(DataType.DateTime)] [Display(Order = 1)] public object Start { get; set; } [Required] [DataType(DataType.DateTime)] [Display(Order = 2)] public object Finish { get; set; } } } I present my models in strongly-typed views using the DisplayForModel and EditorForModel methods. <%= Html.DisplayForModel() %> and <%= Html.EditorForModel() %> But, ASP.NET MVC 2 displays the fields out of order! What might I have wrong?

  • How to handle User "confirmation" with Watir/Cucumber?

    - by Matt Darby
    I'm new to Watir and I've having a little trouble getting logged in in my tests. I use authlogic as my authentication method of choice. When a User registers, they are sent an email with a confirmation link. Clicking this link confirms their account and they can then login. The issue I'm having is how do I confirm the User when using Watir? I have so far: Given /I sign up/ do BROWSER.goto("http://localhost:3000/register") BROWSER.text_field(:id, "user_email").set("[email protected]") BROWSER.text_field(:id, "user_name").set("Foo Bar) BROWSER.text_field(:id, "user_password").set("foo bar") BROWSER.text_field(:id, "user_password_confirmation").set("foo bar") BROWSER.button(:id, "user_submit").click end Given /I am logged in via Watir/ do BROWSER.goto("http://localhost:3000/login") BROWSER.text_field(:id, "user_session_email").set("[email protected]) BROWSER.text_field(:id, "user_session_password").set("foo bar") BROWSER.button(:id, "user_session_submit").click end This correctly populates the fields and the User is saved. Now I try to confirm the User like so: Given /I am confirmed/ do User.last.confirmed! end Unfortunately this doesn't work. What am I missing?

  • How do I implement a remove by index method for a singly linked list in Java?

    - by Lars Flyger
    Hi, I'm a student in a programming class, and I need some help with this code I've written. So far I've written an entire linked list class (seen below), yet for some reason the "removeByIndex" method won't work. I can't seem to figure out why, the logic seems sound to me. Is there some problem I don't know about? public class List<T> { //private sub-class Link private class Link { private T value; private Link next; //constructors of Link: public Link (T val) { this.value = val; this.next = null; } public Link (T val, Link next) { this.value = val; this.next = next; } @SuppressWarnings("unused") public T getValue() { return value; } } private static final Exception NoSuchElementException = null;

  • Passing multiple codeblocks as arguments

    - by doctororange
    I have a method which takes a code block. def opportunity @opportunities += 1 if yield @performances +=1 end end and I call it like this: opportunity { @some_array.empty? } But how do I pass it more than one code block so that I could use yield twice, something like this: def opportunity if yield_1 @opportunities += 1 end if yield_2 @performances +=1 end end and: opportunity {@some_other_array.empty?} { @some_array.empty? } I am aware that this example could be done without yield, but it's just to illustrate. Thanks.

  • make an http post from server using user credentials - integrated security

    - by opensas
    I'm trying to make a post, from an asp classic server side page, using the user credentials... I'm using msxml2.ServerXMLHTTP to programatically make the post I've tried with several configurations in the IIS 5.1 site, but there's no way I can make IIS run with a specified account... I made a little asp page that runs whoami to verify what account the iis process i using... with IIS 5.1, using integrated security the process uses: my_machine\IWAM_my_machine I disable integrated security, and leave a domain account as anonymous access, and I get the same (¿?) to test the user I do the following private function whoami() dim shell, cmd set shell = createObject("wscript.shell") set cmd = shell.exec( server.mapPath( "whoami.exe" ) ) whoami = cmd.stdOut.readAll() set shell = nothing: set cmd = nothing end function is it because I'm issuing a shell command? I'd like to make http post calls, to another site that works with integrated security... So I need some way to pass the credentials, or at least to run with a specified account, and then configure the remote site to thrust that account... I thought that just setting the site to work with integrated security would be enough... How can I achieve such a thing? ps: with IIS6,happens the same but if I change the pool canfiguration I get the following info from whoami NT AUTHORITY\NETWORK SERVICE NT AUTHORITY\LOCAL SERVICE NT AUTHORITY\SYSTEM if I set a domain account, I get a "service unavailable" message... edit: found this http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/275269ee-1b9f-4869-8d72-c9006b5bd659.mspx?mfr=true it says what I supossed, "If an authenticated user makes a request, the thread token is based on the authenticated account of the user", but somehow I doesn't seem to work like that... what could I possibly be missing? edit: well the whoami thing is obviously fooling me, I tried with the following function private function whoami_db( serverName, dbName ) dim conn, data set conn = server.createObject("adodb.connection") conn.open "Provider=SQLOLEDB.1;Integrated Security=SSPI;" & _ "Initial Catalog=" & dbName & ";Data Source=" & serverName set data = conn.execute( "select suser_sname() as user_name" ) whoami_db = data("user_name") data.close: conn.close set data = nothing: set conn = nothing end function and everything seemed to be working fine... but how can I make msxml2.ServerXMLHTTP work with the user credentials???

  • JSON, Ajax login and signup form problem, critique

    - by user552828
    Here is my problem; indexdeneme2.php has two forms Sign up and Login form, and there is validation.js and login.js which are handling the AJAX and JSON response, there are validate.php and login.php which are my scripts for validating and login. When you sign up, it sends the data to validate.php perfectly and validate.php response with JSON perfectly, validate.js must show the error in #error div. validation.js works perfectly if it is working alone. I use same kind of script for login form. Login.php also works perfectly it responses with JSON and login.js shows the errors are appear in #errorlogin div. But this works when login.js works alone. When I try to work login.js and validate.js together, it is not working. validate.php and login.php works perfectly but login.js and validation.js are not working together. They can't handle the responses coming from php scripts. It is not showing the errors in #errorlogin and #error div. They intercept each other I guess. By the way if you can critique my login.php and validate.php I will be really appreciated. Thank you all. this is indexdeneme2.php <?php include('functions.php')?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html;

  • Boiler plate code replacement - is there anything bad about this code?

    - by Benjol
    I've recently created these two (unrelated) methods to replace lots of boiler-plate code in my winforms application. As far as I can tell, they work ok, but I need some reassurance/advice on whether there are some problems I might be missing. (from memory) static class SafeInvoker { //Utility to avoid boiler-plate InvokeRequired code //Usage: SafeInvoker.Invoke(myCtrl, () => myCtrl.Enabled = false); public static void Invoke(Control ctrl, Action cmd) { if (ctrl.InvokeRequired) ctrl.BeginInvoke(new MethodInvoker(cmd)); else cmd(); } //Replaces OnMyEventRaised boiler-plate code //Usage: SafeInvoker.RaiseEvent(this, MyEventRaised) public static void RaiseEvent(object sender, EventHandler evnt) { var handler = evnt; if (handler != null) handler(sender, EventArgs.Empty); } } EDIT: See related question here UPDATE Following on from deadlock problems (related in this question), I have switched from Invoke to BeginInvoke (see an explanation here). Another Update Regarding the second snippet, I am increasingly inclined to use the 'empty delegate' pattern, which fixes this problem 'at source' by declaring the event directly with an empty handler, like so: event EventHandler MyEventRaised = delegate {};

  • Regex to detect a proper permalink?

    - by Fedor
    These permalinks above are rerouted to my page: page.php?permalink=events/foo page.php?permalink=events/foo/ page.php?permalink=ru/events/foo page.php?permalink=ru/events/foo/ The events is dynamic, it could be specials or packages. My dilemma is basically; I need to detect an empty link in order so I can feed a robots no index meta tag in the case of: page.php?permalink=events page.php?permalink=events/ page.php?permalink=ru/events/ page.php?permalink=ru/events I can't use a simple pattern such as [a-zA-Z]+\/?(.+)/ since it won't work on the i18n permalinks. What regex could I use which would detect this, using $_GET['permalink'] as the reference to the permalinks? And avoid false positives? Update: Empty link means there's no fragment after the "events/" part. These are empty: page.php?permalink=events page.php?permalink=events/ page.php?permalink=ru/events/ page.php?permalink=ru/events

  • How do I avoid an infinite loop when overriding a virtual property?

    - by cbsch
    Is it possible to ignore set and get when I'm assigning to or retrieving a value? In specific, I'm inheriting from a class that has a property declared like this: virtual public Int32 Value { get; set; } What I'd like to do is to override it and do something useful in those set and get's. The problem appears when I override it, I also have to manually assign, or return the value from the property. If I do something like this: override public Int32 Value { get { return this.Value; } set { this.Value = value; // do something useful } Then I'm creating an infinite loop. Is there a way to set or get the value without invoking the code in set and get, or do I have to make a separate name for the actual variable?

  • agent-based simulation: performance issue: Python vs NetLogo & Repast

    - by max
    I'm replicating a small piece of Sugarscape agent simulation model in Python 3. I found the performance of my code is ~3 times slower than that of NetLogo. Is it likely the problem with my code, or can it be the inherent limitation of Python? Obviously, this is just a fragment of the code, but that's where Python spends two-thirds of the run-time. I hope if I wrote something really inefficient it might show up in this fragment: UP = (0, -1) RIGHT = (1, 0) DOWN = (0, 1) LEFT = (-1, 0) all_directions = [UP, DOWN, RIGHT, LEFT] # point is just a tuple (x, y) def look_around(self): max_sugar_point = self.point max_sugar = self.world.sugar_map[self.point].level min_range = 0 random.shuffle(self.all_directions) for r in range(1, self.vision+1): for d in self.all_directions: p = ((self.point[0] + r * d[0]) % self.world.surface.length, (self.point[1] + r * d[1]) % self.world.surface.height) if self.world.occupied(p): # checks if p is in a lookup table (dict) continue if self.world.sugar_map[p].level > max_sugar: max_sugar = self.world.sugar_map[p].level max_sugar_point = p if max_sugar_point is not self.point: self.move(max_sugar_point) Roughly equivalent code in NetLogo (this fragment does a bit more than the Python function above): ; -- The SugarScape growth and motion procedures. -- to M ; Motion rule (page 25) locals [ps p v d] set ps (patches at-points neighborhood) with [count turtles-here = 0] if (count ps > 0) [ set v psugar-of max-one-of ps [psugar] ; v is max sugar w/in vision set ps ps with [psugar = v] ; ps is legal sites w/ v sugar set d distance min-one-of ps [distance myself] ; d is min dist from me to ps agents set p random-one-of ps with [distance myself = d] ; p is one of the min dist patches if (psugar >= v and includeMyPatch?) [set p patch-here] setxy pxcor-of p pycor-of p ; jump to p set sugar sugar + psugar-of p ; consume its sugar ask p [setpsugar 0] ; .. setting its sugar to 0 ] set sugar sugar - metabolism ; eat sugar (metabolism) set age age + 1 end On my computer, the Python code takes 15.5 sec to run 1000 steps; on the same laptop, the NetLogo simulation running in Java inside the browser finishes 1000 steps in less than 6 sec. EDIT: Just checked Repast, using Java implementation. And it's also about the same as NetLogo at 5.4 sec. Recent comparisons between Java and Python suggest no advantage to Java, so I guess it's just my code that's to blame? EDIT: I understand MASON is supposed to be even faster than Repast, and yet it still runs Java in the end.

  • Have VB.Net 2010 ErrorProvider Fire on Tabbing Out of BindingSource TextBox on a WinForm

    - by OneSource
    I have a TextBox control on a Windows Form that uses a DataSource custom object as its BindingSource. I have associated an ErrorProvider with the BindingSource like so: Dim dobExample As New DOExample ExampleBS.DataSource = dobExample epExample.DataSource = ExampleBS The ErrorProvider fires if I type a blank space in the TextBox and then press Tab to move to the next control, which is correct. But it doesn't fire if I just press Tab without entering anything. I want the ErrorProvider to show the Error, even if the TextBox is empty and not just validate when there is text in the TextBox. How do I accomplish this? As an additional bit of info, when I execute the following statement: epDOContact.GetError(TextBox) an empty string is returned even though the TextBox is empty when it is required to be present.

  • What is the relationship between WebProxy & IWebProxy with respect to WebClient?

    - by Streamline
    I am creating an app (.NET 2.0) that uses WebClient to connect (downloaddata, etc) to/from a http web service. I am adding a form now to handle allowing proxy information to either be stored or set to use the defaults. I am a little confused about some things. First, some of the methods & properties available in either WebProxy or IWebProxy are not in both. What is the difference here with respect to setting up how WebClient will be have when it is called? Secondly, do I have to tell WebClient to use the proxy information if I set it using either WebProxy or IWebProxy class elsewhere? Or is it automatically inherited? Thirdly, when giving the option for the user to use the default proxy (whatever is set in IE) and using the default credentials (I assume also whatever is set in IE) are these two mutually exclusive? Or you only use default credentials when you have also used default proxy? This gets me to the whole difference between WebProxy and IWebProxy. WebRequest.DefaultProxy is a IWebPRoxy class but UseDefaultCredentials is not a method on the IWebProxy class, rather it is only on WebProxy and in turn, How to set the proxy to the WebRequest.DefautlProxy if they are two different classes? Here is my current method to read the stored form settings by the user - but I am not sure if this is correct, not enough, overkill, or just wrong because of the mix of WebProxy and IWebProxy: private WebProxy _proxyInfo = new WebProxy(); private WebProxy SetProxyInfo() { if (UseProxy) { if (UseIEProxy) { // is doing this enough to set this as default for WebClient? IWebProxy iProxy = WebRequest.DefaultWebProxy; if (UseIEProxyCredentials) { _proxyInfo.UseDefaultCredentials = true; } else { // is doing this enough to set this as default credentials for WebClient? WebRequest.DefaultWebProxy.Credentials = new NetworkCredential(ProxyUsername, ProxyPassword); } } else { // is doing this enough to set this as default for WebClient? WebRequest.DefaultWebProxy = new WebProxy(ProxyAddress, ParseLib.StringToInt(ProxyPort)); if (UseIEProxyCredentials) { _proxyInfo.UseDefaultCredentials = true; } else { WebRequest.DefaultWebProxy.Credentials = new NetworkCredential(ProxyUsername, ProxyPassword); } } } // Do I need to WebClient to absorb this returned proxy info if I didn't set or use defaults? return _proxyInfo; } Is there any reason to not just scrap storing app specific proxy information and only allow the app the ability to use the default proxy information & credentials for the logged in user? Will this ever not be enough if using HTTP? Part 2 Question: How can I test that the WebClient instance is using the proxy information or not?

    I'm trying to replace text that I got back in the ReportViewer using jQuery. My div, wrapped in the table cell, display "empty" as text - which I plan on replacing with my own formatted text on the client side. I can use jQuery just fine to set a class on the div (which is inside a td element). Example: jQuery('div:contains("empty")').addClass('replacetext'); But for some reason I cannot do this: jQuery('div:contains("empty")').replaceWith('<div>Hello World</div>'); I tried this out on some other elements on the page and jQuery does work... but it seems like this issue is ReportViewer (I'm using 2008) specific.

  • .NET Regular Expression to split multiple words or phrases

    - by Cj Anderson
    I'm using the code below to take a string and split it up into an array. It will take: Disney Land and make it two separate elements. If the string contains "Disney Land" then it is one element in the array. Works great, however it adds some empty elements to the array each time. So I just iterate over the elements and remove them if they are empty. Is there a tweak to the code below that will prevent those empty elements from occurring? Private m_Reg As Regex m_Reg = New Regex("([^""^\s]+)\s*|""([^""]+)""\s*") Dim rezsplit = m_Reg.Split(criteria)

  • Idiomatic usage of filter, map, build-list and local functions in Racket/Scheme?

    - by Greenhorn
    I'm working through Exercise 21.2.3 of HtDP on my own and was wondering if this is idiomatic usage of the various functions. This is what I have so far: (define-struct ir (name price)) (define list-of-toys (list (make-ir 'doll 10) (make-ir 'robot 15) (make-ir 'ty 21) (make-ir 'cube 9))) ;; helper function (define (price< p toy) (cond [(< (ir-price toy) p) toy] [else empty])) (define (eliminate-exp ua lot) (cond [(empty? lot) empty] [else (filter ir? (map price< (build-list (length lot) (local ((define (f x) ua)) f)) lot))])) To my novice eyes, that seems pretty ugly because I have to define a local function to get build-list to work, since map requires two lists of equal length. Can this be improved for readability? Thank you.

    can you help me convert following T-SQL funcntion into Oracle. The function converts a string like service|nvretail;language|de;yyyy|2011; to a table. The main problem I have is the usage of the temp table. I could not find any equivalent to it in Oracle.

  • Unidirectional One-to-Many Associations in Entity Framework 4?

    Does EF 4 support unidirectional one-to-many associations, as in: public class Parent { public int Id { get; set; } public string Something { get; set; } public List<Child> AllMyChildren { get; set; } } public class Child { public int Id { get; set; } public string Anotherthing { get; set; } // I don't want a back-reference to the Parent! // public int ParentId { get; set; } } When I try to compile my project with an association between Parent and Child where End2 Navigation is blank (because I unchecked the End2 Navigation Property checkbox in the Add Association dialog), I get Error 2027: No mapping specified for the following EntitySet/AssociationSet - Child.
