Throw a meaningful exception if the attribute to copy does not exists
in the attributes of the TagHelperContext rather than:
`System.InvalidOperationException : Sequence contains no matching
element`.
Added test too.
This change adds more information to ModelAttributes, so that metadata
providers can look at the attributes on the property and type separately
if so desired
This change introduces a new property to ModelMetadata called
IsBindingRequired, which specifies whether or not a model value must be
present on the wire during model binding.
[DataMember(IsRequired = true)] is currently the only thing that will set
this property.
Updated tests and documentation for clarity on the difference in meaning
between MM.IsRequired and MM.IsBindingRequired. Moved setting for
IsRequired to ValidationMetadata which is a better fit.
Also added functional tests for [BindingBehavior] and [DataMember] in
model binding because they were totally missing.
The fix splits client validation and model validation into two separate hierarchies.
Introduced ClientModelValidatorProvider in MvcOptions, which can be iterated to produce IClientModelValidators.
As a result of this, HtmlGenerator code can be free of ActionBindingContext and directly consumes options.
This also means that we do not modify the client validations during resource filters.
- Also modified existing tests to account for aspnet/Razor#332 which fixed models formatting after newline.
- Updated tests for inject to understand new formatting parsing.
aspnet/Razor#332
- Added unit tests to validate that the properties were rendered correctly.
- Modified functional tests to utilize PreElement and PostElement.
aspnet/Razor#341
- #2261
- include `short`, `ushort`, `float`, `double`
- correct typo in `<input/>` tag helper; ignored calculated format
- only one test for `<input/>`'s calculated format 😦
- fill some `Editor*()` and `<input/>` tag helper test gaps
nit: clean up some trailing whitespace
This change caches the actual model metadata instances. Some profiling
showed we didn't go far enough, we were allocating a lot of ModelMetadata
+ ModelPropertyCollection instances.
- set correct `MarkAsHtmlEncodedMethodName` value in `MvcRazorHost`
- handle `HtmlString` values in `TagHelperOutput.Attributes` in `RazorPage`
- special-case double-quotes in `HtmlString` values
- add `static WriteTo()` method for use in tag helpers
- handle non-`string` `output.Attributes` values in tag helpers
- make `TagHelperContentWrapperTextWriter` a `public` class
- provide a `TagHelperContent.Append(object, ...)` extension method
- add `LinkTagHelper.Href` and `ScriptTagHelper.Src` properties
- avoid Razor HTML-encoding these attribute values before their use
- add `JavaScriptEncoder` properties in `LinkTagHelper` and `ScriptTagHelper`
- allow encoding testing without unit testing the default encoder
- handle MVC and Razor changes for this bug in existing tests
- add functional tests of encodings
- add test encoders to TestCommon project
nits:
- correct `InputTagHelper` to pass `type=""` through unchanged
- set correct `TagHelperContentTypeName` value in `MvcRazorHost`
- remove unnecessary `FormTagHelper.Method` and `OptionTagHelper.Selected` properties
- remove complex ternaries and `ShouldAddFileVersion()` methods
- add a few debug assertions
- fix some odd wrapping
- remove or `#if`-out unused `using`s
- remove trailing whitespace
Adding Equals and GetHashCode implementations - the lack of these results
in a lot of boxing.
Removing dead code, not possible to create a model metadata for a
parameter anymore.
- This solves tooling trying to resolve ChunkInheritanceUtility bits for chunks: Aka can't inherit `@using`, `@inject` etc. from _GlobalImport.cshtml
- Added test to validate paths are normalized for DecorateCodeBuilder.
#2271
- remove useless `configuration` variables and `Configuration` instances
- remove "Review" code comment
- unintentionally included in commit 4b5dd19
- reduce repeated code in `TestHelper` for functional tests
- `CreateServer()` methods had duplicate code, an ambiguous match, and an odd order
- rename `GetTestConfiguration()` to `UseCultureReplacer()` in functional tests
- add `IHtmlGenerator.GetCurrentValues()` method
- bring together bits of `GenerateSelect()` and `UpdateSelectListItemsWithDefaultValue()`
- get rid of ugly `out` parameter
- also allows `<option/>` tag helpers to run before `<select/>` helper generation
- match `null` values and `SelectListItem`s with empty values
- match `enum` names correctly
- add doc comments for `IHtmlGenerator.GenerateSelect()` methods
The DataAnnotationsMetadataProvider was setting the bool? IsRequired, all of the
time instead of only setting it to true when we found a RequiredAttribute.
So we never actually executed the fallback logic here. Found
this while working on removing some reflection code from the validator,
and wanted to split it out because it's simple.
- Tooling passes in rooted paths when asking for a RazorParser for a file. This was problematic when resolving inherited code trees and ultimately this commit tests that.
#2213
- #438 part 1/2 and #2027 part 1/3
slight oddity in the XML docs
- unfortunately Roslyn seems to ignore `TypeInfo` being a subclass of `Type`
nit: use correct `warningsAsErrors` datatype in test project.json
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`
- use named parameters more often
- add more comments about returned `ModelBindingResult`
- clean up `ModelBindingResult` doc comments
- cleanup `using`s
Nits:
- cleanup trailing whitespace
- change `retVal` -> `result` in `KeyValuePairModelBinderTest`
- Updated some naming bits that were outdated (referring to ViewStart).
- Added a TagHelperDirective merging mechanic to ensure user file descriptors and inherited descriptors come together correctly.
#2110
These model binders don't have any per-request state so there is no need
for them to be type activated. In one case the model binder actually does
its own caching which is being defeated by the fact that we register it as
type activated.
More changes to come in this area.
- Any Action<ITagHelper, ViewContext> can be registered in DI to allow setting of tag helper properties after any [Activate] properties are set but before their bound from the source document and the tag helper is executed
- Removed previous tag helper options as initializers is the way to do this now
- #1689
- #2162
- see issues aspnet/DependencyInjection#193 and #1612
- use `TryAdd()` in `MvcServices` for the `IAssemblyProvider`
Move `ApplicationBasePath` handling into `RazorPreCompileModule`
- restores view precompilation in functional tests of sample sites
- if we need this, others will as well
- override `IApplicationEnvironment` but get folder from `ProjectContext`
- also remove remaining `IServiceProvider` implementations in this code
test fixes:
- simplify `IApplicationEnvironment` override
- move override logic into `TestHelper.CreateServer()` methods
- remove `LoggerFactory` setup
- does not seem to require special-casing
- remove unused `ITestConfigurationProvider` / `TestConfigurationProvider`
- remove `TestAssemblyProvider` classes
- no longer required
- remove `ReplaceCallContextServiceLocationService` test helper
- change MVC sample to fully-qualify config.json path
- avoids `ReplaceCallContextServiceLocationService` need in `MvcSampleTests`
- no longer required for other tests
nit: remove unused `_serviceProvider` and constructor overload in `RazorPreCompiler`
- compiler given `ApplicationName`, not `ApplicationBasePath`
- @pranavkm wrote the tests prior to 64ddbe0160
nit: rewrap long line introduced in prior commit
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).
- #1468
- Always use `ModelExplorer` in `<select/>`, `DropDownListFor()` and `ListBoxFor()` cases
- allows evaluation of more-complex expressions
- Use `ViewData.Model` in `DropDownList()` and `ListBox()` template cases
- `ViewData` was previously ignored in these cases
nit: change `ViewDataDictionary.Eval()` to return `Model` if `expression` is `null` or empty
- now `throw` on `null` or empty `expression` name in `ViewDataEvaluator.Eval()`
- simplifies some of the higher-level code
- no change to `selectList` fallback; `Model` incorrect for that case
- no change to `GenerateRadioButton()`; would change behaviour unrelated to #1468
- this helper uses incorrect `ViewData` lookup text, see #1487
- see commit 9d5364c
- never correct to pass a `Func<object>` to `GetExplorerForExpression()`
- `<label/>` tests succeeded because that tag helper doesn't use expression result
- `<select/>` tests succeeded because that tag helper gets result from `ViewData`
- does not use `ModelExplorer` due to #1468
nit: update variable names `metadata` -> `modelExplorer`
This change provides caching for the results of searching for view
components and discovering their names.
In our ViewComponent perf test, selecting the component type was about 25%
of the execution of MVC (due to uncached reflection). This change brings
that down to about 1%.
This is a small change to remove uncached reflection. There are some other
code paths where use of view components results in a hotspot. Leaving
those issues to be tracked as part of a larger design issue.
- #944
- name `string` expression name and `Expression<Func<TModel, TResult>>`
parameters "expression"
- single special case is `GenerateIdFromName(string fullName)` since every
other expression name is relative to the current
`ViewData,TemplateInfo.HtmlFieldPrefix` value
- applied from `IHtmlHelper` and `IHtmlGenerator` on up
- name `IHtmlHelper` and `IHtmlHelper<TModel>` parameters "htmlHelper"
- rename `TProperty` and `TValue` type parameters to `TResult`
nits:
- clean up abbreviated names in `CachedExpressionCompiler`
- change `ObjectToDictionary()`'s parameter name to `value`
- use `nameof` more to make renaming (and refactoring) easier in the future
- rewrap parameters and arguments to avoid long lines and orphans
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.
- add `CachedDataAnnotationsMetadataAttributes.UIHint`
- set `ModelMetadata.TemplateHint` using `UIHintAttribute` or `HiddenInputAttribute`
- add doc comments for `TemplateHint`-related properties and methods
- add unit tests and use these attributes in functional tests
nits:
- cache and seal `CachedModelMetadata.IsCollectionType`
- correct doc comments for `ModelMetadata.RealModelType`
- add doc comments for `IsCollectionType`-related properties and methods
- add doc comments for `IsComplexType`-related properties and methods
- move `CachedModelMetadata.IsComplexType` right below `IsCollectionType`
- same for related fields and methods
- #524
- add tests of `DropDownList` and `ListBox` HTML helpers
- extend tests of `<select/>` tag helper
- add scenario to a functional test
New `HtmlHelperSelectTest` does not cover everything. In future (see #453):
- use non-`null` `optionLabel` and `htmlAttributes` arguments
- confirm value sources and their priorities
- mock an `IHtmlGenerator` and confirm how it is called
- mock an `IHtmlHelper` and confirm how extension methods call that
- correct typo in 3303286288
- really seal `CachedModelMetadata.Properties`
- make a couple of test methods `public` (!!)
- add Microsoft.AspNet.PageExecutionInstrumentation to Mvc.sln
- remove `<RootNamespace/>`, `<ProjectExtensions/>`, etc. from .kproj files
services
* Added WithControllersFromServiceProvider that replaces the default
controller activator with a service based one.
* Move activation to DefaultControllerFactory
* Modify [Activate] behavior so that it no longer activates services. Use
[FromService] attribute to hydrate services
Fixes#1707
Attribute route link generation will now have a slight preference for
entries that can use ambient values (vs ignoring an ambient value). This
means that areas will be more 'sticky' with regard to link generation
without the need to specify a better Order.
- #1516
- `allowMultiple == true` when model has a collection type
- ignore any `multiple` attribute in Razor source when generating element
- simplify tests too: fewer error cases
Note Razor author could allow browser user to submit values model binding
will likely ignore: Could mix a `multiple` attribute with a non-collection
`asp-for` expression.
This change makes the attribute route capable of responding to updates in
the action descriptor collection.
The change moves the actual route implementation to InnerAttributeRoute.
AttributeRoute now wraps an InnerAttributeRoute - when processing a route,
AttributeRoute will now check with action descriptor collection if its
InnerAttributeRoute is still 'current' and rebuild it if necessary.
- change `AdditionalValues` type to `IDictionary<object, object>`
- copy `ModelMetadata.AdditionalValues` in `AssociatedMetadataProvider` sub-classes
nits:
- add XML comments
- correct indentation in `CachedModelMetadata`
- #1758
- provide the property bag in `ModelMetadata`; seal it in `CachedModelMetadata`
- add unit tests
- include use of `AdditionalValues` in model binding functional test
nits:
- expose `AdditionalValues` as an `IDictionary` though MVC 5 uses `Dictionary`
- seal `ModelMetadata.Properties` collection as well
- cover a few properties previously missed in `CachedDataAnnotationsModelMetadataTest`
- correct two `ModelMetadataTest` method names
The modelmetadataprovider does significant reflection caching, which shows
up as a hotspot. It's only of our most commonly used services, so not only
do a TON of instances get created, they are very heavy-weight because of
the two ConcurrentDictionary instances they have.
This is a major refactor of how IBinderMetadata interacts with model
binders and value providers. We're doing this to support better
extensibility for metadata in ApiExplorer.
You'll notice a bunch of deleted code in DefaultApiDescriptionProvider
that maps metadata marker interfaces to a fixed list of Api sources. This
is replaced now with IBindingSourceMetadata - which also replaces the
hierarchy of marker interfaces. Now user code can create an arbitrary
binding source and have a consistent API for model-binders,
value-providers and full-visibility in ApiExplorer as
well.
Additonally, there's some error checking in place that better enforces the
constraints we already have in the system. IE you can't create a 'greedy'
model binder that uses value-provider data.
Two additional enhancements are planned for followup PRs:
1. Add a BindingSource property to model-metadata. This will remove some
duplication, but I want to delay it because it would touch another 10 or
so files.
2. Add an extensibility interface for our 'special' model binders like the
file binder so these can show up in ApiExplorer as well.
expire files in razor file cache.
Add a functional test to ensure the compiler cache does not get
initialized until the first request to a View.
Fixes#1708
1. Creates a filter called FormatFilter. This will look at the format parameter if present
in the route data or query data and sets the content type in ObjectResult
2. It adds new options called FormatterOptions, that contains the map of format to content tyepe
3. A method in MVC options to add the formatter mapping
