This change removes reflection from validator providers, and instead
relies on cached metadata in in the modelmetadata.
In general this means that our MVPs don't need to cache anything, they
just look at the metadata and create what they need.
In the case of data-annotations, we update the model details provider to
add validation attributes to the modelmetadata. This would allow someone
to replace the DataAnnotationsValidatorProvider, but still use the
metadata in these attributes.
The change to the IModelValidatorProvider api (to use a context) is
intended to minimize allocations. Currently each validator provider needs
to return a list so you end up with N+1 lists (N validators + a final list
to compine them all). This change will let us just create the final list
(and a small context object). This is a very very high traffic API so it
seemed worth doing.
There's also some general massaging of namespaces and file locations.
- #1865
- change `MutableObjectModelBinder` to ignore exact match in value providers
- had an incorrect assumption: don't want exact model name to match since
this binder supports only complex objects
- also ignored `BinderModelName`, value provider filtering, et cetera
- reduces over-binding e.g. `[Required]` validation within missing properties
also add more tests of #2129 scenarios
- #2129
- do not propagate results with `!IsModelSet`, allowing empty prefix fallback
- adjust `ComplexModelDtoModelBinder` to at least fake-bind all properties
- default values not consistently picked up otherwise
nit: correct 2 test names in `KeyValuePairModelBinderTest`
Separates the MMP into two phases:
1). Creation of the ModelMetadata, discovery of properties and attributes
(reflection) is part of the MMP
2). Lookup of details based on attributes is now part of another phase,
and has its results cached.
Users can now implements and register an IFooMetadataProvider to customize
a single aspect of metadata (see how data annotations does it).
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.
See #1695 for a detailed explanation. This change builds support into the
system for the case that a model binder returns true without setting a
value for the Model.
In this case, validation will be skipped if it's a top-level object.
Note that explicitly setting null will still run validation.
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.
-Checks for ModelType before processing.
-Ignores quotes in ByteArrayModelBinder.
-Unit,functional Tests.
-ModelStateError is set when Covert.FromBase64String(value) throws.
There are several portions of model validation that attempt to avoid
revalidating if a field has been validated. However the behavior of
ModelStateDictionary makes it difficult to distinguish between an
unvalidated field and a field without validation errors. This change
resolves this issue by letting the caller distinguish between the two
cases.
- add missing `[NotNull]` attributes
- remove now-unneeded usings for ...ModelBinding.Internal namespace
Also get ModelBinding test project working under CoreCLR
- create separate k10 and net45 folders under test in VS
- add `[InternalsVisibleTo]` to make `TypeExtensions` visible to test assembly
- correct tests' `CultureInfo` use to compile under CoreCLR
- ifdef out CoreCLR tests depending on Moq, ReadOnly, ...
- remove a couple of tests expecting TypeConverter to work
