  • MVC best practice when adding functions to controller?

    - by Patrick
    Hi I'm writing a function in my controller; this is supposed to take in a form, process it, register the user in DB, send a confirmation email etc etc. to avoid this function to be too cluttered, I was thinking of calling some sub-functions (eg: function registration() { //process form.. _insertInDb($formdata) _send_mail($address); //load confirmation view.. } function _send_mail($to) { //code here } function _insertInDb($formdata) { //other code here... } I'm not sure whether writing all the functions in the controller would be best practice -maybe I should insert all 'supporting' function (eg send_mail and insertInDb in this example) in another file and then import them? This would probably make the controller much more readable.. what's your view?

  • ASP.NET MVC & Windsor.Castle: working with HttpContext-dependent services

    - by Igor Brejc
    I have several dependency injection services which are dependent on stuff like HTTP context. Right now I'm configuring them as singletons the Windsor container in the Application_Start handler, which is obviously a problem for such services. What is the best way to handle this? I'm considering making them transient and then releasing them after each HTTP request. But what is the best way/place to inject the HTTP context into them? Controller factory or somewhere else?

  • Does ASP.Net MVC require you to use master pages?

    - by stocherilac
    My group is working on a new web application and is considering using MVC. However, there are members who would rather include pages than use master pages. Is this possible to do in ASP.NET MVC? In the small amount of time that I've poked around with MVC I have not yet been able to figure out how one might accomplish that.

  • Rendering Views as String with Spring MVC and Apache Tiles

    - by lynxforest
    I am trying to reuse some of my tiles in a controller which is returning a json response to the client. I would like to return a json response similar to the following format: { 'success': <true or false>, 'response': <the contents of an apache tile> } In my controller I would like to perform logic similar to this pseudocode: boolean valid = validator.validate(modelObj) String response = "" if(valid){ response = successView.render() // im looking for a way to actually accomplish // this, where the successView is the apache tiles view. // I would also need to pass a model map to the view somehow. }else{ response = errorView.render() } writeJsonResponse(httpResponse, /* a Map whose json representation looks like the one I described above. */)

  • Two parameters in asp.net mvc route

    - by olst
    Hi. This is a modification to a question I've asked before on this forum. My controller action: public ActionResult SearchResults(string searchTerm, int page)... My view: <%= Html.PageLinks((int)ViewData["CurrentPage"], (int)ViewData["TotalPages"], i => Url.Action("SearchResults", new { page = i }))%>... The route entries: routes.MapRoute( null, "SearchResults", new { controller = "Search", action = "SearchResults", page = 1 } // Defaults ); routes.MapRoute( "Search", "SearchResults/Page{page}", new { controller = "Search", action = "SearchResults" }, new { page = @"\d+" } ); My goal is to have paging links for the search results. The problem is that when I click any page in the paging links, it gives me the search results of an empty serach term. How can I pass the search term parameter which is a string in addition to the page number parameter ? What should I put in the routing ?

  • Stepping through ASP.NET MVC in Action (2009) - and stuck on nunit issue

    - by Jen
    I seem to have missed something - in this step through it talks through downloading nunit and changing the original MSTest reference to NUnit. Which seems fine until it talks about running the test with UnitRun from JetBrains. I would have thought I could run nUnit to be able to run the test - but I load my project in the nUnit gui and I get "This assembly was not built with any known testing framework". This after running the Nunit-2.5.3.9346.msi. Or am I supposed to be able to run tests from within visual studio 2008? After some research I find this: http://www.jetbrains.com/unitrun/ (ie. it seems to be saying this is no longer supported and I'm thinking JetBrains Resharper may cost money?). I'm a little rusty on my NUnit experience. So how do I go ahead and run my test? Is the error message I'm getting considered abnormal? I've added a reference in my MvcApplication.Tests project to the nunit.framework. Is this the wrong reference to add? Thanks :)

  • ASP.NET MVC Inserting object and related object into 2 tables

    - by ile
    I have two tables: Users and UserOwners. Table UserOwners contains list of users that certain user created (list of child-users) - or to be more precise, it contains UserOwnerID and UserID fields. So, now I want to create a new user... in Controller I have something like this: var userOwner = accountRepository.GetUser(User.Identity.Name); var userOwnerID = userOwner.UserID; UserReference userReference = new UserReference(); userReference.UserOwnerID = userOwnerID; if (ModelState.IsValid) { try { //accountRepository.Add(user); //accountRepository.Save(); return View(); } catch { return View(); } } What is the easiest way to add new user to a table Users and matching UserOwner to UserOwners table. Is it suppose to be something like this? public void Add(User user) { db.Users.InsertOnSubmit(user); db.UserReferences.InsertOnSubmit(user.UserReference); } ...or I will have to pass two objects and after adding user I must read it's ID and than assign it to userReference object and add that object to DB? If so, how to read ID of the last object added? Thanks, Ile

  • ASP.NET MVC - how to make users confirm the delete

    - by H4mm3rHead
    He, I have this page where i have checkboxes next to every item in a table, and want to allow the user to select some of them and press my delete button. I just cant come up with the jquery for making the confirm window and submitting only if 'yes' is pushed - this is my page <%Html.BeginForm(); %> <%List<ShopLandCore.Model.SLGroup> groups = (List<ShopLandCore.Model.SLGroup>)Model; %> <%Html.RenderPartial("AdminWorkHeader"); %> <table width="100%" id="ListTable" cellpadding="0" cellspacing="0"> <tr> <td colspan="5" class="heading"> <input type="submit" name="closeall" value="Close selected" /> <input type="submit" name="deleteall" value="Delete selected" /> </td> </tr> <tr> <th width="20px"> </th> <th> Name </th> <th> Description </th> <th width="150px"> Created </th> <th width="150px"> Closed </th> </tr> <%foreach (ShopLandCore.Model.SLGroup g in groups) { %> <tr> <td> <%=Html.CheckBox(g.Id.ToString()) %> </td> <td> <%=g.Name %> </td> <td> <%=g.Description %> </td> <td> <%=g.Created %> </td> <td> <%=g.Closed %> </td> </tr> <%} %> </table> <%Html.EndForm(); %> Please note that its only for the delete that it should confirm, and not necessarily for the close button.

  • ASP.NET MVC Inheriting from ProfileBase

    - by Glen
    I have 2 related issues. I inherited from ProfileBase and I have a couple of properites as such public SomeType PropertyName { get { return (SomeType)base["PropertyName"]; } set { base["PropertyName"] = value; Save(); } } I also have a User class (UserId, UserName, Profile, LastActivityDate) that has 2 additional properties out of the profile that I retrieve in my View to show a list of Users (i.e. @Model.Profile.PropertyName). However, everytime I access a property (from my View) it seems to update the LastActivityDate in the aspnet_Users table because when I show the LastActivityDate as well as the profile properties on my screen the LastActivtyDate is out of sync with the database. Also there is a LastActivityDate property available in my profile which unfortunately is not available and is in fact set to null and throws an exception when accessing it saying the property UserName is null. So the static Create method provided by ProfileBase seems to retrieve the correct profile properties but does not set the base's UserName property even though you pass in a UserName parameter to the Create method. Is this a internal bug? I was kind of hoping if by accessing the property because the LastActivityDate is updated then I could store that value to update my LastActivityDate in my User class before it is rendered to the page. The only way I can think of doing it is: public SomeType PropertyName { get { SomeType result = (SomeType)base["PropertyName"]; OnLastActivityDateChanged(); return result; } set { base["PropertyName"] = value; } } then in my User class: ... public MyProfile() { Profile.LastActivityDateChanged += Profile_LastActivityDateChanged(); } ~MyProfile() { Profile.LastActivityDateChanged -= Profile_LastActivityDateChanged(); } ... void Profile_LastActivityDateChanged(object sender, EventArgs e) { //Run a query to get the latest LastActivityDate this.LastActivityDate = ... } It seems I have to make 1 call to retrieve the full list to my aspnet_Users table then another call for each row just to get the latest activity date. ARGGGGHHH!!! Am I going about this the wrong way! I put an ajax refresh hyperlink next to each User row and when I click it, immediately after loading the page, the value changes. Therefore my suspision is valid that calling a property via the inherited profilebase class updates the value. Is there a workaround? It is a bit miss leading when my page says User Smith has no activity for 4 days then I click my ajax refresh link (or refresh the whole page for that matter) and now it says Smith was active but it was just me meally showing the page that indirectly caused an activity read event.

  • Spring MVC 3.1 How to access HttpSession in Custom Authentication Provider (which implements AuthenticationProvider)

    - by user1506231
    My application calls a web service during the Authentication process (as shown in code below). How can I save some information in HttpSession during this process? This information like customer-account-number will be used in various other places in the application after the user is logged in. Is it possible to pass HttpSession parameter to the MyServiceManager's static login method? public class MyAuthenticationManager implements AuthenticationProvider { @Override public boolean supports(Class<? extends Object> authentication) { return authentication.equals(UsernamePasswordAuthenticationToken.class); } @Override public Authentication authenticate(Authentication authentication) { //MyServiceManager.login - makes a call to web service if(MyServiceManager.login(authentication.getName(), authentication.getCredentials().toString(), XXX_HTTP_SESSION_XXX)) { List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority> (); authorities.add(new GrantedAuthorityImpl("ROLE_USER")); authorities.add(new GrantedAuthorityImpl("ROLE_SUPERVISOR")); return new UsernamePasswordAuthenticationToken(authentication.getName(), authentication.getCredentials(),authorities); } else { return null; } } }
