  • Using multiple databases within one application (ASP.NET MVC, LINQ to SQL)

    - by Alex
    I have a web application made for several groups of people not connected with each other. Instead of using one database for all of them, I'm thinking about making separate databases. This will improve the speed of the queries and make me free from checking to what group the user belongs. But since I'm working with LINQ to SQL, my classes are explicitly connected with the databases, so I will have to make separate DataContexts for all of the databases. So how can I solve this problem? Or should I just not bother and use one database only?

  • 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. */)

  • 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?

  • 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.

  • 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?

The image is stored in /Content/img folder... What am I doing wrong?

  • How to Return A File and a strongly Typed data at the same time?

    - by chobo2
    Hi I am using asp.net mvc 1.0 and I want to return a XML file but I also want to return a strongly typed data back so I can update some fields. Like the XML file will contain users who failed to be inserted into the database. So I want that to appear as a dialog save box what asp.net mvc return file() would do. However I also want to return on the page like values like how many users failed to be added, how many users where added, etc. So I want to use scafolding with the class file I want to pass it along. If this was a view I could pass it along as an object model but I don't see a parameter for that in File(). I also don't want to save the xml file onto the harddrive I want to do it through memory. So have a link that would display on the page to download the file and show the the data I want would not be desired.

  • 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 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

  • Sending data back to Controller Spring-MVC

    - by Umesh Awasthi
    I am not sure if this is a complex problem but as a starting person this seems a bit complex to me. I have an object based on which i need to show some values on the UI and let user select some of them, i need to send data back to another controller when user click on the submit button.Here is the structure of my data object public class PrsData{ private Map<String, List<PrsCDData>> prsCDData; } public class PrsCDData{ private Map<String, Collection<ConfiguredDesignData>> configuredDesignData; } public ConfiguredDesignData{ // simple fields } I have set the object in model before showing the view like model.addAttribute("prsData", productData.getPrData()); In the form i have following settings <form:form method="post" commandName="prsData" action="${addProductToCartAction}" > <form:hidden path="prsCDData['${prsCDDataMap.key}'] [${status.index}].configuredDesignData['${configuredDesignDataMap.key}'] [${configuredDesignDataStatus.index}].code"/> <form:hidden path="prsCDData['${prsCDDataMap.key}'] [${status.index}].configuredDesignData['${configuredDesignDataMap.key}'] [${configuredDesignDataStatus.index}].description"/> </form:form> This is what i have at AddProductToCartController public String addToCart(@RequestParam("productCodePost") final String code, @ModelAttribute("prsData") final PrsData prsData, final Model model, @RequestParam(value = "qty", required = false, defaultValue = "1") final long qty) On submitting the form i am getting following exception org.springframework.beans.NullValueInNestedPathException: Invalid property 'prsCDData[Forced][0]' of bean class [com.product.data.PrsData]: Cannot access indexed value of property referenced in indexed property path 'prsCDData[Forced][0]': returned null It seems like its trying to access the values on this controller while i am trying to send value to that controller and trying to create same object with selected values Can any one tell me where i am doing wrong and what i need to take care of

  • 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 ?

    How do I implement AOP with an annotated Controller?

Am I missing something?

  • 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; } } }

  • Issue with storing items in session in MVC

    - by Sundeep
    I have a customer page on which user can enter multiple locations for customer. I am using telerik ajax grid to display locations, and when a new location is added, I am adding it to session and returning back to the grid. Finally, when user submits, customer and all locations using customerid as reference key gets inserted. I am clearing the session, when user enters create/edit page and on successful commit or any exception occurs. Problem is when user adds the locations for one user and then opens another tab, to create another user then all locations get cleared for previous user. Coz of session, this issue is occuring. Something of viewstate would be page specific. But for ajax grid actions, viewdata/viewbag is not working. Any thoughts on how to implement this. Thanks in advance.

  • ASP.NET MVC 3 NOT showing appropriate view, action called using jquery

    - by TunAntun
    I have a small problem. My action is : public ViewResult SearchForRooms(int HotelDDL) { List<Room> roomsInHotel = bl.ReturnRoomsPerHotel(HotelDDL); return View(roomsInHotel); } Here is the jquery that is calling the action: <script type="text/javascript" language="javascript"> $(document).ready(function () { $("#HotelDDL").change(function () { var text = $("#HotelDDL option:selected").text(); var value = $("#HotelDDL option:selected").val(); alert("Selected text=" + text + " Selected value= " + value); $.post("/Home/SearchForRooms", { HotelDDL: $("#HotelDDL option:selected").val() }); }); }); </script> And finally, here is the View that should be called: @model IEnumerable<RoomReservation.Entities.Entities.Room> @{ ViewBag.Title = "Search"; } <h2>Result</h2> <table> <tr> <th> City </th> <th> Hotel </th> <th> Room label </th> <th> Number of beds </th> <th> Price per night </th> <th></th> </tr> @foreach (var item in Model) { <tr> <td> @Html.DisplayFor(modelitem=>item.Hotel.City.Name) </td> <td> @Html.DisplayFor(modelItem => item.Hotel.Name) </td> <td> @Html.DisplayFor(modelItem => item.Name) </td> <td> @Html.DisplayFor(modelItem => item.NumberOfBeds) </td> <td> @Html.DisplayFor(modelItem => item.PricePerNight) </td> </tr> } </table> Everthing is working ok (databse return all rooms correctly) except final view rendering. I have tried Phil's tool but it doesn't give me any suspicious hints: RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes); So, why is it not showing after jscript send it's post method to SearchForRooms()? Thank you P.S. If you need any other piece of code please just say so.

  • Unique visitor counting in ASP.NET MVC

    - by Max
    I'd like to do visitor tracking similar to how stackoverflow does it.. By reading through numerous posts, I've figured out some details already: Count only 1 IP hit per 15 minutes (if anonymous) Count only 1 unique user-Login (per day?) Now that leaves the question of the real implementation.. Should I log the two factors live into a table (and increase count) | IP | timestamp | pageurl | Or do the counting AFTERWARDS (e.g. using IIS log files - which don't include the user, right? I know there're some similar posts outside, but NONE really has a great solution in my opinion yet..

  • ASP.NET MVC routing and paths is js files

    - by HiveHicks
    Hello, we're facing a problem now. We have a pretty big page with a loooong inline script, which does all the work. We now want to obfuscate it and use it as a separate .js file. But the problem is that we have paths which are generated by Url helper (Url.Content()). So what is the best way to separate js file from the page and not using hard-coded path strings?

  • Passing contextual info to Views in ASP.NET MVC

    - by Andrey
    I wonder - what is the best way to supply contextual (i.e. not related to any particular view, but to all views at the same time) info to a view (or to master page)? Consider the following scenario. Suppose we have an app that supports multiple UI languages. User can switch them via UI's widgets (something like tabs at the top of the page). Each language is rendered as a separate tab. Tab for the current language should not be rendered. To address these requirements I'm planning to have a javascript piece that will hide current's language tab on the client. To do this, I need current's language tab Id on the client. So, I need some way of passing the Id to master page (for it to be 'fused' into the js script). The best thing I can think of is that all my ViewModels should inherit some ViewModeBase that has a field to hold current language tab Id. Then, whatever View I'm rendering, this Id will always be available for the master page's hiding script. However, I'm concerned that this ViewModelBase can potentially grow in an uncontrolled fashion as number of such pieces of contextual info (like current language) will grow.. Any ideas?
