I am thinking of implementing a generic Controller in ASP.NET MVC.
PlatformObjectController<T>
where T is a (generated) platform object.
Is this possible? Is there experience / documentation?
One related question for example is how the resulting URLs are.
yes it is, you just can't use it directly but you can inherit it and use the childs
here is one that I use:
public class Cruder<TEntity, TInput> : Controller
where TInput : new()
where TEntity : new()
{
protected readonly IRepo<TEntity> repo;
private readonly IBuilder<TEntity, TInput> builder;
public Cruder(IRepo<TEntity> repo, IBuilder<TEntity, TInput> builder)
{
this.repo = repo;
this.builder = builder;
}
public virtual ActionResult Index(int? page)
{
return View(repo.GetPageable(page ?? 1, 5));
}
public ActionResult Create()
{
return View(builder.BuildInput(new TEntity()));
}
[HttpPost]
public ActionResult Create(TInput o)
{
if (!ModelState.IsValid)
return View(o);
repo.Insert(builder.BuilEntity(o));
return RedirectToAction("index");
}
}
and usages:
public class FieldController : Cruder<Field,FieldInput>
{
public FieldController(IRepo<Field> repo, IBuilder<Field, FieldInput> builder)
: base(repo, builder)
{
}
}
public class MeasureController : Cruder<Measure, MeasureInput>
{
public MeasureController(IRepo<Measure> repo, IBuilder<Measure, MeasureInput> builder) : base(repo, builder)
{
}
}
public class DistrictController : Cruder<District, DistrictInput>
{
public DistrictController(IRepo<District> repo, IBuilder<District, DistrictInput> builder) : base(repo, builder)
{
}
}
public class PerfecterController : Cruder<Perfecter, PerfecterInput>
{
public PerfecterController(IRepo<Perfecter> repo, IBuilder<Perfecter, PerfecterInput> builder) : base(repo, builder)
{
}
}
