POMVC2 sending collections from the view a controller via json
text
Body
copied!<p>I've been looking on forums for 2 days now and can't find a good answer so I'll just post it.</p> <p>I appear to be having a problem posting JSON back to the controller to save. The JSON should map to model view but it keeps getting default(constructor)values rather then the values from the POST.</p> <p>We have a series of JS widgets that contain a data field with json in them. We do all our data manipulation in these widget objects on the client side. When a user wants to save we grab the data we need from the widgets involved and we put it into another JSON object that matches a ViewModel and POST that back to the server.</p> <p>For example:</p> <pre><code> $("#Save").click(function () { if (itemDetails.preparedForSubmit() && itemConnections.preparedForSubmit()) { itemComposite.data.Details = itemDetails.data; itemComposite.data.Connections= itemConnections.data; $.post(MYURL, itemComposite.data); } else { alert("failed to save"); } }); </code></pre> <p>The preparedForSubmit() method simple does stuff like any validation checks or last minute formatting you might need to do client side.</p> <p>The itemDetails widgets data matches a ViewModel.</p> <p>The itemConnections widgets data matches a collection of ViewModels.</p> <p>The Controller looks like this:</p> <pre><code> [HttpPost] virtual public JsonResult SaveItemDetailsComposite(ItemComposite inItemData) { if (ModelState.IsValid) { try { _Mapper.Save(itemComposite.Details , itemComposite.Connections); return Json(true); } catch (Exception ex) { _log.Error("Exception " + ex.InnerException.Message); throw; } } return Json(SiteMasterUtilities.CreateValidationErrorResponse(ModelState)); } </code></pre> <p>The ItemComposite Class is a simple View Model that contains a single itemDetails object and a collection of itemConnections. When it returns data to here it is just getting the default data as if it got a new ItemComposite rather than converting the POST data.</p> <p>in Firebug I see the data is posted. Although it looks weird not automatically formatted in firebug.</p>
