On A c# mvc website, I created a controller with the name NotFound, and then created a default route to an index action on the controller. When I debugged the program it went to the correct controller action but did not display anything in the view. Does any one know why?
did you do:
return View("some view name");
in the action method?
what does the some view name.aspx contain?

I am new to CodeIgniter 4.
I have one controller named Pages and helps to display website pages normally. Then I have another controller named Admin which is suppose to load the admin view with its own header and footer files.
While Pages controller works fine, the Admin controller keeps saying 404-file not found admin.
I think I have a problem with my current Route settings below. Please help.
$routes->setDefaultController('Pages');
$routes->setDefaultMethod('default');
// Route Definitions
$routes->get('/', 'Pages::index');
$routes->get('(:any)', 'Pages::default/$1');
try ajusting your code like this.
$routes->setDefaultController('Pages');
$routes->setDefaultMethod('default');
// Route Definitions
$routes->resource('pages');
$routes->get('/', 'Pages::index');
$routes->get('(:any)', 'Pages::default/$1');
What can be used to get the URL of the page which is in this path of the project <website>/Pages/Account/Logout.cshtml
This is using view model razor pages and not mvc controller/action
When I use Url.Action("/Account/Logout", new { logoutId = ogoutId }); it says cannot resolve action /Account/Logout
In Razor Pages, you could use #Url.Page.
Logout
Or use asp-page directly,see more usage here.
<a asp-page="/Account/Logout" asp-route-logoutId ="1">Logout</a>
This might be a very silly question because I'm new to PHP frameworks. But I have got the concept of MVC framework. But this routing thing is very confusing me.
I created a controller and view for dashboard and set it as default. Then I wanted to check if the user is logged in then send him to the login page if it's not.
So, what I did in the routes is this:
$route['default_controller'] = 'dashboard/index';
$route['login'] = 'login';
But even if I add a thousand more controllers and routes, it still goes to the default i.e the dashboard. This was supposed to work http://localhost/codeigniter/login. I'm very sure I haven't put a redirect-to-dashboard code in the login page.
at first it's important to understand to routing in codeigniter.
The key for understanding is $route['url/path'] = controller/method (or "public function")
So. In your case, you routing to Login controller and index method (or index function...this it interpretation of codeigniter )
If you want to check if is user logged or not, you may try to check for examle session variable inside of called functon. But it depends on your application. But I think that is not good idea to check it in routes.php
Hope it helps you.
The default controller in routes, will be the controller that opens your index or first page.
If your first page is in controller "pages", then that is your default controller. Do not use it for your secure dashboard pages
Your first page should be the index method in the controller. It should look like this
$route['default_controller'] = "pages";
Where pages is your first page controller
I have a subsite within my main site for site Administration. The site is physically stored in the form
~/Views/Administration/ViewName/Index
With controllers inside
~/Controllers/Admin/ControllerName
I am getting an exception trying to visit the page.
The view 'index' or its master was not found or no view engine
supports the searched locations. The following locations were
searched: ~/Views/ViewName/index.aspx ~/Views/ViewName/index.ascx
~/Views/Shared/index.aspx ~/Views/Shared/index.ascx
~/Views/ViewName/index.cshtml ~/Views/ViewName/index.vbhtml
~/Views/Shared/index.cshtml ~/Views/Shared/index.vbhtml
I added a route
routes.MapRoute(
"Administration", // Route name
"Administration/{controller}/{action}/{id}", // URL with parameters
new { controller = "Administration", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
Going directly to the page manually
http://localhost:999/Administration/BaseItem/index
Does not result in exception, but I get no content. This leads me to believe it is not finding the View. What am I doing wrong?
I think the issue is that I have told the route engine how to route to the Controller, but I have not told the system how to route to the View. Where do I tell the system where the views are?
The problem is not with the routes, but with the design. The view engine cannot find your view, because it cannot find the correct path, since the default view engines are not designed to search for a subsite.
Instead of creating a subsite, make Administration an Area in your project. In AdministrationAreaRegistration.cs, you will set a route similar to the route you added. Place your views in the Views folder inside the Administration folder (inside the Area folder), and everything will work properly.
How can I create a login partial view in MVC 2.0?
I want to include this in several masterpages in my site since I can't use the login control in MVC.
What code do I put in the controller which will accept the username and password?
The default MVC project creates one for you. Just install MVC and create a MVC project. It will have a Master page, with a login partial view already created.
