- use new `ModelMetadata.HtmlEncode` property in HTML helpers
- specifically in default HTML display and editor object templates (e.g.
`@Html.DisplayFor()`) when value is non-`null` and the template is invoked
with template depth greater than 1
- similar to MVC 5.2 commit [2b12791aee4f](https://aspnetwebstack.codeplex.com/SourceControl/changeset/2b12791aee4ffc56c7928b623bb45ee425813021)
nits:
- remove dupe `null` check in `DefaultDisplayTemplates.ObjectTemplate()`
- move backing fields initialized with constants together in `ModelMetadata`
The change here is to always use the provided formatter, instead of using
it as a fallback. This is much less surprising for users.
There are some other subtle changes here and cleanup of the tests, as well
as documentation additions.
The primary change is that we still want to run 'select' on a formatter
even if it's the only one. This allows us to choose a content type based
on the accept header.
In the case of a user-provided formatter, we'll try to honor the best
possible combination of Accept and specified ContentTypes (specified
ContentTypes win if there's a conflict). If nothing works, we'll still run
the user-provided formatter and let it decide what to do.
In the case of the default (formatters from options) we do conneg, and if
there's a conflict, fall back to a global (from services)
JsonOutputFormatter - we let it decide what to do.
This should leave us with a defined and tested behavior for all cases.
This is the routing part of the fix. MVC will be updated as well
(attribute routing).
As the graph of routers is traversed, routers add themselves to the
current 'path', which unwinds on a failed path.
This mechanism is opt-in. Whoever adds something needs to remove it as
part of cleanup. If a router in the tree doesn't interact with the
.Routers property, then there are no consequences for those that do.
Additionally, fixing #116 as part of the same change. This means that we
create a nested 'RouteData' and then restore it on the way out. This is
simpler than just dealing with the .Routers property in isolation.
- ensure `ViewDataDictionary` constructors are not passed a `null` or
`Mock.Of<IModelMetadataProvider>()` instance
- `ViewDataDictionary` constructors always use the `IModelMetadataProvider`
- `viewData.ModelMetadata` now never `null`
- `ViewDataDictionary<int>.Model` no longer throws if read before it's written
- `ViewDataDictionary.ModelMetadata` now copied to new instances in fewer cases
- e.g. don't use unusual `object` datatype with customized `ModelMetadata`
- `null` checks can generally be removed but in one case needed to
special-case metadata for `object`
nit: remove duplicate empty `string` check in
`ExpressionMetadataProvider.FromStringExpression()`
- ensure correct `ViewData.ModelState` value in a `RazorPage` instance
- let view components inherit `ViewData.Model` from surrounding context
- do not create an isolated `ViewDataDictionary<TModel>` in one HTML helper
- allows previous `ViewDataDictionary<TModel>` constructor to be `internal`
- also add comments for that constructor
- change two `ViewDataDictionary` copy constructor calls to avoid uselessly
copying `Model` and related information from source
- `ViewDataDictionary<TModel>` constructors now pass `typeof(TModel)` to base
`protected` constructors
- move type compatibility checks into base `ViewDataDictionary`
- remove `ViewDataDictionary<TModel>.ModelMetadata` override
- don't retrieve `ModelMetadata` twice in a single constructor invocation
- remove newly-unused `protected` properties and use `private` fields in copy
constructors
Address longstanding problems found (see #1466)
- avoid reusing `ModelMetadata` after `Model` value changes
- reset `ModelMetadata` backing field in `Model` setter
- `Model` and `ModelMetadata.Model` could previously get out of sync
- carry `ModelMetadata` forward from an outer scope only if `Model` matches
- previously two scopes could have different `Model` values but share their
`ModelMetadata` (and `ModelMetadata.Model`)
- related to previous item but didn't require `Model` setting; switching
to a property of the same type as containing `Model` was enough
- avoid NRE if `ViewDataDictionary<int>.Model` is read before it's written
- problem affected all non-`Nullable` value types
- `ViewDataDictionary.ModelMetadata` setter should throw if value is `null`
nits:
- add and reword doc and code comments
- `ViewDataDictionary<TModel>` constructors should only inherit base's
parameter descriptions; have more information in the derived class
- make a few `ViewDataDictionary` properties get-only
- clean up `using` statements in `ViewDataDictionary<TModel>`
- make two constructors `internal`
This change adds the concept of a full-name to viewcomponents. View
components can be invoked using either the short name or long name. If the
provided string contains a '.' character, then it will be compared against
full names, otherwise it will be matched against short names only.
The short name is used for view lookups.
If the name is explicitly set via ViewComponent attribute, then the full
name is the name provided. The short name is the portion of the name after
the last '.'. If there are no dots, then the short name and full name are
the same.
If the name is not set explicitly, then it is inferred from the Type and
namespace name. The short name is the Type name, minus the 'ViewComponent'
suffix (if present). The full name is the namespace of the defining class,
plus the short name.
- Added utility methods to construct valid SyntaxTreeNodes that represent the @removetaghelper directive.
- Added parse level unit tests to validate the @removetaghelper generates an accurate SyntaxTreeNode.
- Added parse level unit tests to validate the @removetaghelper throws with bad formats.
- Added TagHelperRegistration unit tests to validate the AddOrRemoveTagHelperCodeGenerators are understood and affect the descriptors found.
- Added Designtime mapping tests to validate correct source mappings are made to ensure proper coloring and lack-of C# intellisense.
- Added end-to-end tests to validate @removetaghelper can essentially disable TagHelpers on a page.
