Using BetterCMS 2.0.6.192 directly from NuGet. Brand new c# project.
I've been through the setup multiple times but cannot get a Server Widget to call custom Controller/View code.
I am attempting to create a custom server widget. I have the Phonebook.cshtml in the View/Widgets folder and registered as as Widget on a page in the site. This widget view will render with some simple html but when I try to Post or render a partial view I get an error "No route in the route table matches the supplied values".
Within the Phonebook.cshtml widget I have added
#{ Html.RenderAction("Index", "Phonebook", new {Area = ""}); }
but the partial view is not found. The error message, seen on the page with the widget is,
"Error rendering view "~/Views/Widgets/Phonebook.cshtml": No route in the route table matches the supplied values.".
I have a PhonebookController in the /Controllers folder in the /Views folder I have an Index.cshtml. While debugging the Index view is never fired.
I have also tried adding
#{ Html.RenderAction("Index", "Phonebook", new { Area = "Phonebook" }); }
to the /Views/Widgets/Phonebook.cshtml. I have /Areas/Phonebook/Controllers/PhonebookController.cs and /Areas/Phonebook/Views/Index the Index action is never fired.
I think it might have to do with routing. In the PhonebookAreaRegistration.cs file I have
context.MapRoute( "Phonebook_default", "Phonebook/{controller}/{action}/{id}", new { action = "Index", id = UrlParameter.Optional } );
In the /App_Start/RouteConfig.cs I have commented out the default routing as instructed in the docs.
Help.
This is a cross posted in Better CMS forum, not sure how much traffic that forum gets anymore. http://www.bettercms.com/support/widgets-and-modules/struggling-with-server-widget/
Rookie mistake. Forgot to register Routes in Global.asax.cs file.
Old Code- Does not work:
protected void Application_Start()
{
cmsHost = CmsContext.RegisterHost();
cmsHost.OnApplicationStart(this);
}
New Code- Works:
protected void Application_Start()
{
cmsHost = CmsContext.RegisterHost();
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
cmsHost.OnApplicationStart(this);
}

I am new in MVC 4 web development and i am creating a control panel. I have developed a Add user page and submit information in database successfully.
But after submit when i press back button it will show previous form.
i am using redirection the page to same page after submit form.
here is the code to redirect
public ActionResult AdminPanel(RegisterUserModel user)
{
if (ModelState.IsValid) // Check the model state for any validation errors
{
if (user.AddUserToDB(user.username, user.password, user.fullName,user.contactNo,user.COAId)) // Calls the Login class checkUser() for existence of the user in the database.
{
TempData["SuccessMessage"] = "User Added Sucessfully!";
ModelState.Clear();
return Redirect("AdminPanel");
}
else
{
ViewBag.SuccessMessage = "User Not Added";
return View();
}
}
SelectList clientsList = GetClinetList();
ViewBag.clientsList = clientsList;
return View(); // Return the same view with validation errors.
}
I have tried many examples but issue not resolved yet so kindly give my suggesstions
If you don't want the user to be able to see the previous content when clicking back, then you must indicate that content should not be cached by the browser and must revalidate with the origin server
A summary of this behaviour is here - http://blog.55minutes.com/2011/10/how-to-defeat-the-browser-back-button-cache/
You could create a nocache attribute, like this one - https://stackoverflow.com/a/10011896/1538039, and apply it to your controller methods.
I have a simple controller action that creates a Guest record and renders a template.
// First bind the form to our Guest:
$form->bind( $_POST, $guest );
// Validate and save, or show error messages
if( $form->isValid($_POST, $guest) ) {
if( $guest->save($_POST) ) {
$this->view->setMainView( 'confirm' );
}
}
This works fine before I add any mailer stuff. However, when I add an event handler inside the Guest model which happens to render a template, the controller renders a WHITE SCREEN OF DEATH instead of my confirm template.
In Guest model:
public function afterCreate() {
return GuestMailer::sendEmailConfirmation( $this );
}
In GuestMailer class:
public static function sendEmailConfirmation( $guest ) {
// create/configure $email message
$view = $guest->getDI()->get('simpleView');
$view->render( // Works without this call...
'confirmation_email',
array( 'guest' => $guest )
);
$content = $view->getContent();
$email->content( $content );
return $email->send();
}
Note that when I remove the above call to render(), the confirm template is rendered successfully.
I thought components in Phalcon were supposed to be highly decoupled? Why is rendering a completely different template causing my controller's view to get messed up? How can I avoid this?
I think this problem is caused by a peculiar configuration of the templating service, in a normal workflow it doesn't causes issues, they appears when you need to render "manually" a template as in your case, you can refer to this PhalconPHP forum discussion linked, in particular the answer refered by the link anchor:
http://forum.phalconphp.com/discussion/109/manually-render-separate-file-template-#C12015
i have two controllers outside the areas and a few areas for my application
my Layout page contains a partial view rendering code:
#Html.Action(actionName: "LoginBar", controllerName: "Login")
and it is registered in RouteConfig
routes.MapRoute(
name: "LoginBar",
url: "loginbar",
defaults: new
{
controller = "Login",
action = "LoginBar"
});
when i browsing page in HomeController: /home it works well
when i'm trying to browse pages inside areas: /contentedit/articles the exception throws on a line #Html.Action:
InvalidOperationException: No route in the route table matches the supplied values.
any ideas why this exception throws and what code modifications I need?
Inside #Html.Action(actionName: "LoginBar", controllerName: "Login") you can give area as object route like this way :
#Html.Action("LoginBar","Login",new { area = "//your area name//" })
I'm using MVC4 with Entity Framework and like many people I'm new to MVC and trying to get my head around the design patterns.
I have a partial view that displays a list of sessions followed by actionlinks allowing the authenticated member to book into the sessions.
Note: for clarity, I've chopped out most of the code, if a member is booked into a session, it displays "Booked" instead of the action link.
#using OnlineBookings.Website.Models
#{ DateTime currentDate = DateTime.MinValue.Date; }
<form method="post" action="~/Controllers/BookSessionController.cs">
#foreach (SessionsWithBookingInformation s in Model)
{
<p>#s.StartTime.ToString("t")
#s.Description
#Html.ActionLink(
"Book",
"BookSession",
new { sessionId = s.SessionId }
)
</p>
}
</form>
This then displays as part of a larger view:
The actionlinks pass the guid of the session to be booked through to the following function in my controller, which retrieves the memberId from the cookie and uses Entity Framework to create a booking for that member and session.
public ActionResult BookSession(Guid sessionId)
{
using (var db = new OnlineBookingsEntities())
{
// see if the member id is stored in a cookie
if (Request.Cookies["memberId"] != null)
{
var memberId = new Guid(Request.Cookies["memberId"].Value);
db.Bookings.Add(new Booking
{
BookingId = Guid.NewGuid(),
MemberId = memberId,
SessionId = sessionId,
BookingTime = DateTime.Now
});
db.SaveChanges();
}
}
// this refreshes the entire page
/// is there a better way to just replace the actionlink they clicked on?
return RedirectToAction("Index", "Home");
}
All this is working nicely and bookings are being effectively recorded.
But, I'm trying to figure is if the return from the BookSession function can just update the actionlink text.
Ideally, on success, I want to replace the ActionLink in my partial view with the word "Booked" and on failure I want to replace it with the failure condition like "Session full".
Or I could just update my partial view, because that will do the same thing.
Am I missing something simple here? Or, am I barking up entirely the wrong tree?
Your question is great and really well explained, but it's also a little vague since it's a bit of a "What should I do?" question. Here are a few options that might help you develop a solution.
Redisplay the same view. Return whichever view the user was on for them to submit the link. This will look like a simple refresh.
return View();
Submit the request via AJAX and update via a partial view. Put an id tag on a span or similar HTML element with an individual booking's details inside. Submit the request with AJAX, perhaps via #Ajax.ActionLink, and have your action return a partial view.
return PartialView("_OnlineBookingPartial", model);
Once your partial view is returned, update the specific booking with the data returned.
Use AJAX again, but return JSON. Another way might be that you use AJAX again but instead you return JSON and do something with it. You could, for example, return text in which you would replace Book with; i.e. "Session full" or "Booked!".
return new JsonResult
{
Data = "Booked!"
}
Personally, I'd probably use AJAX to update with a non-AJAX (non-Javascript) fallback.
You can do this by using #Ajax.ActionLink and checking if the request is AJAX or not inside your controller action.
if (Request.IsAjaxRequest) {
return PartialView("_OnlineBookingPartial", model);
}
return View();
This means that if the browser has Javascript enabled and supports AJAX, it will be used and the whole process will be seamless and instant for the user. If Javascript is disabled, the page will simply refresh.
I like the way MVC4 manage the new logon screen: it is possible to have a modal dialog showed.
I tried to reproduce the same behavior in the same solution for another view. But it doesn't work because Request.QueryString["content"] is null. I don't know why. In fact, there is an action method called ContextDependentView (generated by the MVC template) where the trick occurred. Here it is:
private ActionResult ContextDependentView()
{
string actionName = ControllerContext.RouteData.GetRequiredString("action");
if (Request.QueryString["content"] != null)
{
ViewBag.FormAction = "Json" + actionName;
return PartialView();
}
else
{
ViewBag.FormAction = actionName;
return View();
}
}
If the value of Request.QueryString["content"] is not null then we display a partial view (modal jQuery) otherwise it is a classic view.
Can someone help me understand why this is not working?
PS: another thread already exists but without any solution.
The login and register links are bound to a click handler in AjaxLogin.js which then adds content=1 in loadAndShowDialog
