    <p>Okay, I've been struggling with this for a while now.</p> <p>I have a standard MVC2 project and use EF4 to access data objects. Many of my data objects (and therefore database tables) have two common fields: UpdateUserAccountID and UpdateDate.</p> <p>In each of my controllers, I am currently setting this fields manually within each controller on the Edit action:</p> <pre><code> // POST: /Modes/Edit/2 [HttpPost] public ActionResult Edit(int id, FormCollection formValues) { Mode mode = _repository.GetMode(id); //Set update flags mode.UpdateUserAccountID = _userRepository.GetUserID(User.Identity.Name); mode.UpdateDate = DateTime.Now; try { UpdateModel(mode); _repository.Save(); return RedirectToAction("Details", new { id = mode.ModeID }); } catch { return View(mode); } } </code></pre> <p>Problem is, I want to update these two fields in a central place, regardless of the type of the controller. I am using Repository/IRepository pattern for my data objects. I also have set up a BaseController as I thought I could pass in my 'mode' object in the example above to a generic function in a base controller to set these two fields. But, I couldn't figure that out and the generic function has no awareness of these specific fields.</p> <p>Should I be creating a base class for my repositories instead? I can't envisage how that would work within the MVC framework. In webforms, I would just have had an interface that all my models implement with the common fields but i can't seem to fit it in to an MVC approach.</p> <p>Any help as to the approach to take would be great.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
