Plugin caching issue

Hello,

I am developing a plugin for nopCommerce 3.1.

I use the ICacheManager to cache some models in my controller but the problem is that nothing is actually cached.

I tried to debug the CacheExtensions to see if something is added, and I see that my key and model are added to the cache collection.

The problem is that at the next request it seems that nothing is cached.

I am also sending a snippet of the code:

public ActionResult PublicInfo()
{
....
string cacheKey ="My-cache-key{0}-{1}";
var cachedModel = _cacheManagerr.Get(cacheKey,100, () =>
                                                                  {
                                                                     return new MySampleMode(){
                                                                            Products = products;
                                                                      }
....

}


}

I believe you need to explicitly register for the cache manager in DependencyRegistrar, since there's a few implementation of cache managers in nopCommerce. Try searching for the following in Nop.Web.Framework.DependencyRegistrar, and do the same in the DependencyRegistrar of your plugin. :)

builder.RegisterType<AclService>().As<IAclService>()
                .WithParameter(ResolvedParameter.ForNamed<ICacheManager>("nop_cache_static"))
                .InstancePerHttpRequest();

Thank you so much for the reply.

There is no specific cache plugin. But you can cache your plugin viewmodel per httprequest, to do that you have to use  IStaticCacheManager by giving a unique cachekey name like

//It is better to use a more unique and specific key depending on your requirement.

var myPluginCacheByProductId_KEY=string.Format("Nop.myplugin.cache-{0}", productid);
var myPluginCacheByProductId_PATTERN_KEY = "Nop.myplugin.cache";
var cacheManager = EngineContext.Current.Resolve<IStaticCacheManager>();
return cacheManager.Get(myPluginCacheByProductId_KEY, () =>
            {
                //Do your stuff and return your viewmodel
               return yourviewmodel;
            });

There is a lot example of using static and memory cache in the source code. Just keep in mind that for httprequest you have to use IStaticCacheManager, others are the same whatever it is plugin or source code. Also, consider that, you may need to clear the cache depending on some interaction. Then you have to use

 _cacheManager.RemoveByPattern(myPluginCacheByProductId_PATTERN_KEY);
