In particular, the fact that ApplicationController is the only
one inheriting from AC::API is not a default. You could say at
most that generators generate them that way, but the creation
of controllers is something which is out of our control because
programmers write controllers by hand.
Instead, we can say that normally, conventionally, as in the
majority of Rails apps, that is the actually the case.

- skip calling helper_method if it's not there: if we don't have helpers, we needn't define one.
- tests that an api controller can include and use ActionController::Cookies

* Introduce `Response#strong_etag=` and `#weak_etag=` and analogous options
for `fresh_when` and `stale?`. `Response#etag=` sets a weak ETag.
Strong ETags are desirable when you're serving byte-for-byte identical
responses that support Range requests, like PDFs or videos (typically
done by reproxying the response from a backend storage service).
Also desirable when fronted by some CDNs that support strong ETags
only, like Akamai.
* No longer strips quotes (`"`) from ETag values before comparing them.
Quotes are significant, part of the ETag. A quoted ETag and an unquoted
one are not the same entity.
* Support `If-None-Match: *`. Rarely useful for GET requests; meant
to provide some optimistic concurrency control for PUT requests.

purpose?" heuristics
Narrows the "are you in a browser, viewing the page?" check to exclude
non-GET requests. Allows content-less APIs to use implicit responses
without having to set a fake request format.
This will need further attention. If you forget to redirect from a POST
to a GET, you'll get a 204 No Content response that browsers will
typically treat as… do nothing. It'll seem like the form just didn't
work and knowing where to start debugging is non-obvious.
On the flip side, redirecting from POST and others is the default, done
everywhere, so it's less likely to be removed or otherwise missed.
Alternatives are to do more explicit browser sniffing.

There was some subtle breakage caused by #18774, when we removed
`#original_exception` in favor of `#cause`. However, `#cause` is
automatically set by Ruby when raising an exception from a rescue block.
With this change, we will use whichever handler has the highest priority
(whichever call to `rescue_from` came last). In cases where the outer
has lower precidence than the cause, but the outer is what should be
handled, cause will need to be explicitly unset.
Fixes #23925

Default rendering behavior if respond_to collector doesn't have a block.
|
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | | |
When a `respond_to` collector doesn't have a response, then a
`:no_content` response should be rendered. This brings the default
rendering behavior introduced by
https://github.com/rails/rails/issues/19036 to controller methods
employing `respond_to`
|
| | | | |
|
| | | |
| | | |
| | | |
| | | |
| | | |
| | | | |
This method will only be added when used with Ruby 2.3.0 or greater.
This method has the same behavior as `Hash#dig`, except it will convert
hashes to `ActionController::Parameters`, similar to `#[]` and `#fetch`.

When trying to make a request and the request doesn't have a suitable template, the new error messages are really helpful but there's a small (and I mean, VERY small) typo that has been bugging me for the last few days. This adds the space and restores order to the universe. :heart:

This reverts commit 45a75a3fcc96b22954caf69be2df4e302b134d7a.
HWIAs are better than silently deeply-stringified hashes... but that's a
reaction to a shortcoming of one particular session store: we should not
break the basic behaviour of other, more featureful, session stores in
the process.

1. Conceptually revert #20276
The feature was implemented for the `responders` gem. In the end,
they did not need that feature, and have found a better fix (see
plataformatec/responders#131).
`ImplicitRender` is the place where Rails specifies our default
policies for the case where the user did not explicitly tell us
what to render, essentially describing a set of heuristics. If
the gem (or the user) knows exactly what they want, they could
just perform the correct `render` to avoid falling through to
here, as `responders` did (the user called `respond_with`).
Reverting the patch allows us to avoid exploding the complexity
and defining “the fallback for a fallback” policies.
2. `respond_to` and templates are considered exhaustive enumerations
If the user specified a list of formats/variants in a `respond_to`
block, anything that is not explicitly included should result
in an `UnknownFormat` error (which is then caught upstream to
mean “406 Not Acceptable” by default). This is already how it
works before this commit.
Same goes for templates – if the user defined a set of templates
(usually in the file system), that set is now considered exhaustive,
which means that “missing” templates are considered `UnknownFormat`
errors (406).
3. To keep API endpoints simple, the implicit render behavior for
actions with no templates defined at all (regardless of formats,
locales, variants, etc) are defaulted to “204 No Content”. This
is a strictly narrower version of the feature landed in #19036 and
#19377.
4. To avoid confusion when interacting in the browser, these actions
will raise an `UnknownFormat` error for “interactive” requests
instead. (The precise definition of “interactive” requests might
change – the spirit here is to give helpful messages and avoid
confusions.)

Use `each_byte` instead of `bytes` to speed up string xor operation and

While iterating an AC::Parameters object, the object will mutate itself
and stick AC::Parameters objects where there used to be hashes:
https://github.com/rails/rails/blob/f57092ad728fa1de06c4f5fd9d09dcc2c4738fd9/actionpack/lib/action_controller/metal/strong_parameters.rb#L632
If you use `permit` after this iteration, the `fields_for_style` method
wouldn't return true because the child objects are now AC::Parameters
objects rather than Hashes.
