Hi there
The most popular approach to using NH with asp.net is session per request model. So, in one request I load some data, present them to the user and close the session. In the next request the user wants to modify the data, eg. modify the order of items in a listbox that correspond to some ordered entities collection. On the server side, I receive the list of object ID's, and their new ordering numbers. The question is: how to persist this update back to the db? Do I have to reload entities based on their IDs, change ordering and update them? It seems like a huge waste - I don't need any information from db, I have everything right here: IDs and the new ordering, I don't need the rest of their fields. On the other hand I could use Session Per Conversation pattern along with saving entities in the session. But this time I create unnecessary memory overhead, since I'm keeping in session data, that I already have on a webform. It breaks the "stateless" part of http, where usually statless means also scalable. So I'd rather use the first route, but is there any way to do it without handcrafting the update with CreateSqlQuery? Is there any way to use some dummy object (like entity without not null constraints) to pass to nhibernate only fields that should be updated, along with object id? thanks a lot HP --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "nhusers" group.
