POHow can I return an object from a method executed with RedirectToAction?
text
Body
copied!<p>I have a controller with Get, Save and Create actions. These actions take as a parameter an item type. This is just a string specifying what type of item we are processing.</p> <p>There is a child controller for each of these item types, and each of these child controllers implement the child controller interface (IChildController) which has the Get, Save and Create methods.</p> <p>Each child controller is named based on its type (ItemTypeController). When I'm getting an item from my parent controller, I can do it like this:</p> <pre><code>Get(string itemType, int id) { return RedirectToAction("Get", itemType, new { id }); } </code></pre> <p>The Get method in the child controllers has an ActionResult return type (returns a Partival View) so this works without problem.</p> <p>However, when I'm saving an item, all children are created and then returned to the parent object and stored within it so that a save can be performed on the parent only (and NHibernate will take care of cascading records).</p> <p>How can I return objects from these methods without instantiating all the child controllers first. For example, I'd like to be able to call Save(itemType, item)</p> <pre><code>Save(string itemType, Item item) { return RedirectToAction("Save", itemType, new { item }); } </code></pre> <p>and then we will find the appropriate child controller (itemTypeController), execute the method Save(item), and then return the item (item) back to the parent controller.</p> <pre><code>Save(Parent parent) { IRepository<Parent> _parent; var item = new Parent(); item.Id = parent.Id; item.Children = parent.Children.AddAll(parent.Children.Select(Save(parent.ChildType)); // save each child and add it to the parent's child collection return _parent.Save(item); } Save(Child child) { IRepository<Child> _child; var item = new Child(); item.Id = child.Id; return _child.Save(item); } </code></pre> <p>What is the best solution to achieve this? Thanks in advance for any help.</p> <p><strong>EDIT</strong> </p> <p>How would I go about converting complex objects into ViewModels. For example, a Parent object that contains children of type Child.</p> <p>In the ParentTypeController we have:</p> <pre><code>ParentViewModel ToViewModel(Parent parent) { var model = new ParentViewModel(); model.Id = parent.Id; model.Children = parent.Children.Select(ToViewModel); //Use the ToViewModel method in the ChildTypeController return model; } </code></pre> <p>ChildTypeController:</p> <pre><code>ChildViewModel ToViewModel(Child child) { var model = new ChildViewModel(); model.Id = child.Id; return model; } </code></pre>
