This also fixes#1503.
Currently all model binders except mutable object binder are independent of validation code. The mutable object binder which needs to do some validation ( for scenarios involving [BindRequired] and [BindNever]).
We would be going with an approach where required validaiton happens in input formatters and model binders.
This is needed as validation for value types can best be done at creation time.
Followup PRs:
Introduce support for skipping validation (and not binding) for a particular property/type etc.
This change makes ApiDescription and ApiParameterDescription aware of all
of the new features we built into model binding for enhanced DTO support
(uber-binding).
The main change is that instead of sticking just to the declared
parameters on the action itself, we now traverse model metadata and break
the parameters down based on their logical data source.
This means that a model like the below will yield 3 parameters:
public class ProductChangeCommandDTO
{
public int Id { get; set; }
[FromBody]
public ProductDetails Changes { get; set; }
[FromQuery]
public string AdminComments { get; set; }
[FromServices]
public IProductRepository Repository { get; set; }
}
The 'Repository' will be hidden, as it's not related to user input.
Additionally, we treat different sources differently. In the
above example, 'Changes' is from the body and will be treated as a
leaf-node.
However if you use nested DTOs that are bound from the query string (using
[FromQuery]) or similar, we'll recursively explore to find as much
structure as possible.
This information is combined with data from the route template to give a
much more complete picture than we ever could in the past for parameters,
especially when DTO/Command pattern is used.
This is a new filter stage that surrounds the existing model binding,
action, and result parts of the pipeline. Resource Filters run after
Authorization Filters.
The other major change is to support one of the primary scenarios for
Resource Filters. We want a filter to be able to modify the inputs the
model binding (formatters, model binders, value providers, etc) -- this
means that those changes need to be held on a context object and preserved
so that they can be used in the controller.
So, IActionBindingContextProvider is removed - the ActionBindingContext
will be created by the invoker. For now it will be part of the action
context.
- StyleCop working again (handles C# 6.0 additions) though only locally for me
- disable some new rules:
- ConstFieldNamesMustBeginWithUpperCaseLetter
- InstanceReadonlyElementsMustAppearBeforeInstanceNonReadonlyElements
- StaticReadonlyElementsMustAppearBeforeStaticNonReadonlyElements
- StaticReadonlyFieldsMustBeginWithUpperCaseLetter
- PrefixCallsCorrectly
- correct remaining violations
- lots of long lines for example
- use more `var`; some manual updates since StyleCop doesn't check seemingly-unused blocks
nit: remove new trailing whitespace (was paranoid about adding it w/ fixes)
- #EngineeringDay
- VS does not yet format auto-properties nicely; reverted what it did
Also revert changes under
- test/Microsoft.AspNet.Mvc.Razor.Host.Test/TestFiles
- #EngineeringDay
- Total replaced: 660 Matching files: 270 in *.cs
- Total replaced: 250 Matching files: 32 in all other files
- Total replaced: 22 Matching files: 8 in a few stragglers
Did not change files under following directories
- test\Microsoft.AspNet.Mvc.Razor.Host.Test\TestFiles\Output
- test\Microsoft.AspNet.Mvc.FunctionalTests\compiler\resources
- test\WebSites\TagHelpersWebSite
(Razor generates trailing whitespace in a case or two)
This allows model binding to once again be independent of routing. Sending
RouteContext into model binding was an odd choice from a layering
point-of-view.
* Modify ReflectedActionInvoker to model bind parameters
* Introduce IBodyReader for reading request bodies
* Introduce types for per-action-context specific binders, value providers
and body readers
