- #1485, #1487
- handle `TemplateInfo.HtmlFieldPrefix` in `ViewDataEvaluator.Eval()`
- attempt lookup in the `ViewDataDictionary` using full name then evaluate
relative `expression` against `viewData.Model`
- handle `null` or empty `expression` special case in this method (remove `throw`s)
- always pass relative `expression` name into `Eval()`
- remove `null` or empty `expression` handling from higher-level code
- in a couple of cases, special-case returned `ViewDataInfo`
- #2662
- remove incorrect guard from `DefaultHtmlGenerator.GenerateRadioButtion()`
- add doc comments for the core methods that have changed
- enable unit tests skipped due to one of above bugs
- fix one (yeah, just one) other test with incorrect expectations
- remove functional test comments about the above bugs and update expectations
nits:
- move some comments describing `ViewDataEvaluator` methods above the methods
- #2664
- use new property to correctly determine `isTargetEnum` in `GetCurrentValues()`
- avoid `ArgumentNullException` in all cases where raw values are `enum` but target is not
- stop skipping tests blocked by #2664, exposing a couple more #1487 issues
- use new property instead of private `GetElementType()` methods where possible
- cleans up some duplicate code
- also remove redundant use of `IsCollectionType` and `ElementMetadata`
nits:
- move properties above methods in `ModelMetadata`
- avoid accidentally-incorrect "Remove Unnecessary Usings"
- test additional cases _close_ to these bugs as well
for #1485
- show odd `@Html.CheckBox()`, `@Html.Hidden()` behaviour in unit tests
- show odd `@Html.TextBox()` behaviour in functional tests (templates)
for #1487
- show odd `@Html.Value()` behaviour in unit tests
- show odd `@Html.RadioButton()`, `@Html.TextArea()` behaviour in functional tests
- show lack of validation attributes for `@Html.RadioButton()`, `<select>` tag helper
for #2662
- show odd `@Html.RadioButton(string.Empty)` behaviour in functional tests
for #2664
- show failures with `@Html.ListBox()` in unit tests
nits:
- test `IHtmlHelper` methods, not extensions
- use `ViewData`, not `ViewBag` in `HtmlGeneration_FormController`
- name test methods a bit more consistently
- rename `HtmlHelperValueExtensionsTest` to `HtmlHelperValueTest`
This is the first step is some more refactorings to come in the future
with the goal of making MVC less monolythic. This makes the core of MVC
more reusable and more in line with the design of other vNext platform
components.
With this change, Mvc.Core contains just the minimal guts needed to build
a working app.
- Action Discovery
- Action Invoker
- Filters
- ObjectResult
- Model Metadata
- Model Binding
- Formatters
- Validation System
And yes, we are aware of the irony of 'minimal MVC' not including the view
system. The idea is that this is the kernel of an MVC app, and anything
real is layered on top.
The most noticable impact of this change is that MvcOptions has been blown
apart into more managable chunks. See the various ConfigureMvc*** methods.
The new Mvc.Extensions package is a placeholder while we evaluate and tune
the new definitions. Expect more changes as features are move to their own
packages, and in some case their own repositories.
For now there is no experience to bootstrap an Mvc.Core app. That's coming
next.
