POASP.NET MVC URL generation for links choosing wrong route with HTTP method constraints
text
Body
copied!<p>I have the following routes specified - MyHttpMethodConstraint is one that checks the HTTP Method overriden by form a variable.</p> <pre><code>routes.MapRoute("Retrieve", "{controller}/{id}/{action}", new { action = "retrieve" }, new { action = "create|retrieve|update|delete", httpMethod = new MyHttpMethodConstraint("GET", "HEAD"), id = new GuidRouteConstraint() }); routes.MapRoute("Update", "{controller}/{id}", new { action = "update" }, new { action = "update", httpMethod = new MyHttpMethodConstraint("PUT"), id = new GuidRouteConstraint() }); routes.MapRoute("Delete", "{controller}/{id}", new { action = "destroy" }, new { action = "delete", httpMethod = new MyHttpMethodConstraint("DELETE"), id = new GuidRouteConstraint() }); routes.MapRoute("Create", "{controller}", new { action = "create" }, new { action = "create", httpMethod = new MyHttpMethodConstraint("POST") }); </code></pre> <p>Everthing is routed correctly incoming to the Actions, however URL generation for Url.ActionLink's do not work as I hoped (using the routes that are constrained to HTTP GET methods) but instead finding the ones that are constrained to POST/PUT/DELETE and thus the wrong URLs. I have tried re-ordering the routes but this does not help. I expect that that URL-generation ignores the constraints.</p> <p>Is there a workaround, apart from building my own ActionLink method? </p> <p><strong>EDIT</strong></p> <p>There is also a default route at the bottom of the list:</p> <pre><code>routes.MapRoute("Default", "{controller}/{action}", new { controller = "home", action = "index" }); </code></pre>
