Change mentions of `app/views/shared` in the guides to be
`app/views/application` instead. View partials rely on the same
[Template Inheritance][] as their template counterparts, so the guides
should encourage end-users to benefit from that inheritance.
> This makes `app/views/application/` a great place for your shared
> partials, which can then be rendered in your ERB as such:
>
```html+erb
<%# app/views/admin/products/index.html.erb %>
<%= render @products || "empty_list" %>
<%# app/views/application/_empty_list.html.erb %>
There are no items in this list <em>yet</em>.
```
To enforce that template resolution, this commit also replaces
references to `shared/` with `application/` in the Rails test suite.
[Template Inheritance]: https://guides.rubyonrails.org/layouts_and_rendering.html#template-inheritance
In #33418, documentation from `ActionView::Helpers::RenderingHelper#render`
was copied to `ActionController::Renderer#render` with the intention of
documenting `ActionController::Rendering#render`. Since then, further
documentation has been added to `ActionController::Renderer#render`, and
`ActionController::Renderer#render` has been mistaken for
`ActionController::Rendering#render` (for example, in #46045).
This commit adds documentation to `ActionController::Rendering#render`
(which was previously `:nodoc:` because it is a simple override of
`AbstractController::Rendering#render`), and updates related
documentation to point to `ActionController::Rendering#render`.
The way the guide is written now, it's not clear if the first counter value will be `0` or `1`, so I made it explicit that it's `0`.

If the media attribute is omitted, the default for web browsers is "all", meaning that by default links apply to all media.
Before:
```ruby
> stylesheet_link_tag "style"
=> <link href="/assets/style.css" media="screen" rel="stylesheet" />
```
After:
```ruby
> stylesheet_link_tag "style"
=> <link href="/assets/style.css" rel="stylesheet" />
```
The current behavior is not going to change for existing applications.
For newly built applications, the media attribute is not going to be added by default. Which can be configured using the following:
```
Rails.application.config.action_view.stylesheet_media_default = false
```
This links the first mention of each method to its API documentation,
similar to a Wikipedia article. Some subsequent mentions are also
linked, when it suits the surrounding text.
In https://github.com/rails/rails/pull/37919, support
for rendering objects that respond_to render_in in
controllers was added. However, the implementation
did not support layouts.
This change updates the implementation from #37919
to more closely match the rest of the
ActionView::Template classes, enabling the use of layouts.

Not having the comma changes the meaning of the word - from "any way" with no comma, to "but actually" with a comma. It is the latter meaning the guides are intending.
Convert examples to use `form_with` instead of `form_for` or `form_tag`,
which have been soft-deprecated. Also rename form variable in examples
from `f` to `form`, as exemplified by 8ff7ca5d11.
Most of this section was written from the time that render file: was the
default, before CVE-2016-0752.
This updates the guide to the Rails 6 `render file:` behaviour, moves it
to a more appropriate part of the file.
[ci skip]
Most of these examples no longer work. The ability to render an absolute
path was removed as part of CVE-2016-0752. In Rails 6 we changed `render
file:` to only take exact paths and always to render them as raw files.
Rendering a template with its extensions _is_ supported, but I don't
think should be recommended.
This also removes `render file:` from an example where it isn't
relevant.
[ci skip]
[ci skip] A regular expression was used to find a lot of missing Oxford
commas and add them. The regular expression was as follows.
", ([a-zA-Z0-9.\`:'\"]+ ){1,6}(or|and) "
- Remove mention about `ActionView::TemplateHandlers` since this
module was removed by c1304098cca8a9247a9ad1461a1a343354650843.
Change word `subclasses` to `nested classes`.
See c7408a0e40545558872efb4129fe4bf097c9ce2f
- Remove useless sentence "Beginning with Rails 2, the standard extensions
are `.erb` for ERB (HTML with embedded Ruby), and `.builder` for Builder (XML generator)."
While the code example was not unsafe, it
encourages the use of confusingly unsafe APIs
(specifically `html_safe`). We have a safe
alternative and we should encourage people to use
it under all circumstances.
* The example code on this page are similar to ones generated
by scaffold generator, but some points are different.
* Of course, it is no reason to be as same as scaffolding codes.
But this is the guide for beginners, I thought it's better
to be almost same as scaffolding codes.
