Généralement, lorsque vous vous retrouvez à lutter contre un cadre de pratiques standard, il est temps de reconsidérer votre approche. Dans ce cas, le comportement de ModelState. Par exemple, lorsque vous ne voulez pas l'état du modèle après un POST, envisagez une redirection vers le fichier get.
[HttpPost]
public ActionResult Edit(MyCmsPage page, string submitButton)
{
if (ModelState.IsValid) {
SomeRepository.SaveChanges(page);
return RedirectToAction("GenerateSeoTitle",new { page.Id });
}
return View(page);
}
public ActionResult GenerateSeoTitle(int id) {
var page = SomeRepository.Find(id);
page.GenerateSeoTitle();
return View("Edit",page);
}
MODIFIÉ pour répondre au commentaire sur la culture:
Voici ce que j'utilise pour gérer une application MVC multiculturelle. Tout d'abord, les sous-classes du gestionnaire d'itinéraire:
public class SingleCultureMvcRouteHandler : MvcRouteHandler {
protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
{
var culture = requestContext.RouteData.Values["culture"].ToString();
if (string.IsNullOrWhiteSpace(culture))
{
culture = "en";
}
var ci = new CultureInfo(culture);
Thread.CurrentThread.CurrentUICulture = ci;
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(ci.Name);
return base.GetHttpHandler(requestContext);
}
}
public class MultiCultureMvcRouteHandler : MvcRouteHandler
{
protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
{
var culture = requestContext.RouteData.Values["culture"].ToString();
if (string.IsNullOrWhiteSpace(culture))
{
culture = "en";
}
var ci = new CultureInfo(culture);
Thread.CurrentThread.CurrentUICulture = ci;
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(ci.Name);
return base.GetHttpHandler(requestContext);
}
}
public class CultureConstraint : IRouteConstraint
{
private string[] _values;
public CultureConstraint(params string[] values)
{
this._values = values;
}
public bool Match(HttpContextBase httpContext,Route route,string parameterName,
RouteValueDictionary values, RouteDirection routeDirection)
{
// Get the value called "parameterName" from the
// RouteValueDictionary called "value"
string value = values[parameterName].ToString();
// Return true is the list of allowed values contains
// this value.
return _values.Contains(value);
}
}
public enum Culture
{
es = 2,
en = 1
}
Et voici comment je câbler les itinéraires. Après avoir créé les routes, j'ajoute mon sous-agent (example.com/subagent1, example.com/subagent2, etc.) puis le code de culture. Si vous n'avez besoin que de la culture, supprimez simplement le sous-agent des gestionnaires de routes et des routes.
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("Content/{*pathInfo}");
routes.IgnoreRoute("Cache/{*pathInfo}");
routes.IgnoreRoute("Scripts/{pathInfo}.js");
routes.IgnoreRoute("favicon.ico");
routes.IgnoreRoute("apple-touch-icon.png");
routes.IgnoreRoute("apple-touch-icon-precomposed.png");

foreach (System.Web.Routing.Route r in routes)
{
if (r.RouteHandler is MultiCultureMvcRouteHandler)
{
r.Url = "{subagent}/{culture}/" + r.Url;
//Adding default culture
if (r.Defaults == null)
{
r.Defaults = new RouteValueDictionary();
}
r.Defaults.Add("culture", Culture.en.ToString());
//Adding constraint for culture param
if (r.Constraints == null)
{
r.Constraints = new RouteValueDictionary();
}
r.Constraints.Add("culture", new CultureConstraint(Culture.en.ToString(), Culture.es.ToString()));
