    <p>I've got a URL routing issue in my application. I've tried to tackle the issue, but haven't really made any headway.</p> <p>So, I'm making the following AJAX request client-side:</p> <pre><code>$.ajax({ type: 'GET', url: programState.getBaseUrl() + 'Playlist/GetPlaylistsByUserId', dataType: 'json', data: { userId: user.get('id') }, success: function (data) { console.log("JSON data:", data); }, error: function(error) { console.error(error); } }); </code></pre> <p>Here's the network:</p> <p><img src="https://i.stack.imgur.com/IKlWe.png" alt="enter image description here"></p> <p>Here's the server error:</p> <p><img src="https://i.stack.imgur.com/Xm4NU.png" alt="enter image description here"></p> <p>Here's the Controller's methods for GET and GetPlaylistsByUserId:</p> <pre><code>[HttpGet] public ActionResult Get(Guid id) { Playlist playlist = PlaylistDao.GetById(id); return new JsonDataContractActionResult(playlist); } [HttpGet, ActionName("GetPlaylistsByUserId")] public ActionResult GetPlaylistsByUserId(Guid userId) { IList&lt;Playlist&gt; playlists = PlaylistDao.GetByUserId(userId); return new JsonDataContractActionResult(playlists); } </code></pre> <p>and finally, here are my routes:</p> <pre><code>routes.MapRoute( "getPlaylistsByUserId", "{controller}/{userId}", new { controller = "Playlist", action = "GetPlaylistsByUserId" }, new { httpMethod = new HttpMethodConstraint("GET") } ); routes.MapRoute( "post-Playlist", "{controller}", new { controller = "Playlist", action = "create" }, new { httpMethod = new HttpMethodConstraint("POST") } ); routes.MapRoute( "get-Playlist", "{controller}/{action}/{id}", new { controller = "Playlist", action = "get" }, new { httpMethod = new HttpMethodConstraint("GET") } ); routes.MapRoute( "put-Playlist", "{controller}", new { controller = "Playlist", action = "update" }, new { httpMethod = new HttpMethodConstraint("PUT") } ); routes.MapRoute( "delete-Playlist", "{controller}/{id}", new { controller = "Playlist", action = "delete" }, new { httpMethod = new HttpMethodConstraint("DELETE") } ); routes.MapRoute( "Default", "{controller}/{action}/{id}", new {controller = "Home", action = "Index", id = UrlParameter.Optional} ); </code></pre> <p>As best as I can tell -- I am getting my URL routed to my 'Get' action, but I am intended it to be routed to the 'GetPlaylistsByUserId' action. I believe this to be happening because the server error states that it is looking for a paramater 'id' for method 'Get.'</p> <p>I'm not sure why any of this would be happening, though, as I seem to quite clearly have my other action mapped...?</p>

    1. COTry your original code but with a nullable Guid? as the parameter. See if it gets through to the correct Action handler and then check for userid.HasValue

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
